[0086] As described in the background technology, the hammer and / or cutting member of the emergency device in the related art is normally exposed, which is easy to cause accidental injury and poses a safety hazard. The inventor has found that the reason for this problem is that the hammer and / or cutting member of the emergency device in the related art is set on the telescopic member, and the hammer or cutting member is selected as the working member according to the use requirements. However, the above-mentioned cutting member and / or hammer are exposed to the outside under normal conditions and in use, which is easy to cause accidental injury, so there is a safety hazard.

[0087] In response to the above technical problems, the embodiment of the present application provides an emergency device, by providing a receiving cavity in the gripping member, when the telescopic member is in the retracted state, the working member (hammering member or cutting member) can be stored in the receiving cavity to avoid being exposed outside the receiving cavity. With such a configuration, when the working member is in a normal state (i.e., the hammering member or cutting member is not in use, i.e., when the working member is in a non-emergency state), it can be stored in the receiving cavity, i.e., stored in the receiving cavity, which can avoid accidental injury and thus reduce safety hazards.

[0088] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0089] To facilitate the description of the embodiments of the present application, the coordinate system in the accompanying drawings is first described, wherein the Z-axis direction is the first direction, which may be the telescopic direction of the telescopic member, the X-axis direction is the second direction, which may be the axial extension direction of the hammer member (or the second direction may be the extension direction of the functional body when the functional body is in the first position), and the Y-axis direction is the third direction (the Y-axis direction may be the first axis extension direction of the functional body rotating around the telescopic member). By way of example, the X-axis, Y-axis, and Z-axis constitute an orthogonal coordinate system or a non-orthogonal coordinate system. Preferably, the X-axis, Y-axis, and Z-axis constitute an orthogonal coordinate system, and the third direction is perpendicular to the first direction and the second direction.

[0090] like Figures 1 to 3As shown, the emergency device provided in the embodiment of the present application includes a telescopic member 100, a gripping member 400 and an action member, wherein the action member includes a hammering member 200 and / or a cutting member 720, and the action member is arranged on the telescopic member 100, and the action member can be selectively installed on the telescopic member 100 according to user needs. The telescopic member 100 is connected to the gripping member 400. Exemplarily, the telescopic member 100 includes a telescopic rod 110, and along a first direction, the telescopic rod 110 includes a first end and a second end arranged oppositely, wherein the action member can be arranged at the first end of the telescopic rod 110, and the second end of the telescopic rod 110 is connected to the gripping member 400, that is, the gripping member 400 is arranged at the second end of the telescopic rod 110.

[0091] For example, if the telescopic member 100 is provided with a hammer 200, the emergency device can be used as a life-saving hammer, and the hammer 200 can be used to break glass or the like, including but not limited to vehicle glass, house glass, and other glass that hinders escape. The end of the hammer 200 is conical or pyramidal, so that the hammer 200 can break glass, etc.

[0092] Alternatively, the telescopic member 100 is provided with a cutting member 720, and the cutting member 720 has a cutting blade 721, and the emergency device is used as a cutter, and the cutting blade 721 can be used to cut a belt-like object, which can be a vehicle seat belt or the like; alternatively, the telescopic member 100 is provided with a hammer member 200 and a cutting member 720, and the emergency device can be used as a life-saving hammer or a cutter, and the embodiments of the present application are not limited to this.

[0093] The telescopic member 100 can be retracted to adjust its length, and then adjust the distance between the action member and the holding member 400 along the first direction, so that the user can use the emergency device in different situations. For example, the elongated telescopic member 100 can make the distance between the holding member 400 and the hammering member 200 longer. When the holding member 400 moves at the same angular velocity, the longer the distance between the holding member 400 and the hammering member 200, the faster the linear velocity of the hammering member 200, so that the hammering effect of the hammering member 200 is better. For another example, when the emergency device is used in a small space, the retractable telescopic member 100 makes the distance between the holding member 400 and the hammering member 200 shorter, which is convenient for using the emergency device in the small space. For another example, the elongated telescopic member 100 can make the distance between the holding member 400 and the cutting member 720 longer, and cut a strip with a long distance.

[0094] For example, Figure 4As shown, the telescopic rod 110 includes at least two telescopic sections 111 that are connected in sequence, and the telescopic rod 110 includes a first telescopic section 111a and a second telescopic section 111b, wherein the first telescopic section 111a may be a first telescopic section, and the second telescopic section 111b may be a tail telescopic section, and when the telescopic rod 110 is in an extended state, the first telescopic section is located at the first end of the entire telescopic rod 110, and the tail telescopic section is located at the second end of the entire telescopic rod 110, and when the telescopic rod 110 is in a retracted state, the first telescopic section can be retracted into the tail telescopic section. For example, the hammering member 200 and / or the cutting member 720 are installed on the first telescopic section, and the gripping member 400 is installed on the tail telescopic section.

[0095] The grip 400 is used to provide a gripping position for the user to grasp. The grip 400 has a housing 401. The grip 400 is configured to have a shell that is at least partially hollow. The first wall 421 of the grip 400 surrounds the housing 401, and the housing 401 is located at the end of the grip 400. The telescopic member 100 is inserted into the housing 401, and part of the telescopic member 100 is arranged in the grip 400, that is, the housing 401 can accommodate part of the telescopic member 100. In this way, the emergency device can be miniaturized.

[0096] like Figures 5 to 10 As shown, when the telescopic member 100 is in a retracted state, the telescopic member 100 can be located in the gripping member 400, and the action member is accommodated in the accommodating chamber 401. For example, the rear telescopic section can be arranged in the gripping member 400 and connected to the gripping member 400. When the emergency state is in a normal state, the telescopic member 100 can be in a retracted state, and the front telescopic section is retracted to the rear telescopic member, that is, the entire telescopic member 100 can be stored in the gripping member 400. At this time, the action member arranged on the front telescopic member can be accommodated in the accommodating chamber 401 to prevent the action member (cutting member 720 and / or hammer member 200) from being exposed.

[0097] Compared with the solution in the related art in which the hammering member 200 and the cutting member 720 of the emergency device are normally exposed and have potential safety hazards, the emergency device provided in the embodiment of the present application can be accommodated in the accommodating cavity 401 when the working member is in a normal state (the hammering member 200 or the cutting member 720 is in an unused state), that is, it is stored in the accommodating cavity, which can avoid accidental injuries and thus reduce potential safety hazards.

[0098] like Fig.11 and Fig.12 As shown, the holding piece 400 provided in the embodiment of the present application includes a first sleeve 420, the telescopic piece 100 is inserted into the first sleeve 420, the first sleeve 420 includes the above-mentioned first wall body 421, the first wall body 421 surrounds the accommodating cavity 401, and the telescopic piece 100 is inserted into the accommodating cavity 401, and part of the telescopic piece 100 is located in the holding piece 400.

[0099] It is understandable that the gripping member 400 includes a first gripping portion 901, and the first gripping portion 901 is configured for a user to grip. For example, when the emergency device is used as a window breaker, the user grips the first gripping portion 901, and the telescopic member 100 is in an extended state, thereby increasing the torque of the hammering member 200, thereby increasing the hammering effect.

[0100] Furthermore, the above-mentioned first sleeve 420 can be configured so that the first gripping portion 901 is located in the first sleeve 420 ; on this basis, the gripping piece 400 provided in the embodiment of the present application also includes a first main body 410 , and the first main body 410 can be configured so that the first gripping portion 901 is located in the first main body 410 .

[0101] For example, the first gripping portion 901 is located at the first sleeve 420, or the first gripping portion 901 is located at the first body 410, or the first gripping portion 901 is located at the first sleeve 420 and the first body 410. When the first gripping portion 901 provided in the embodiment of the present application is located at the first sleeve 420 and the first body 410, the gripping area of ​​the gripping member 400 can be increased.

[0102] Furthermore, the first body 410 includes at least three legs 411 in a folded state, and when the at least three legs 411 are opened, they can be supported on a support surface to support the telescopic member 100, that is, to support the emergency device. When the at least three legs 411 are folded, each leg 411 is folded to form the first body 410, and the first body 410 and the first sleeve 420 form a first columnar structure, and the first gripping portion 901 is located in the first columnar structure.

[0103] In one embodiment, the first sleeve 420 is fixed relative to the telescopic member 100 and does not slide relative to it. For example, the first body 410 includes three legs 411, the length direction of each leg 411 extends along the first direction, the first end of the leg 411 is rotatably connected to the first sleeve 420, the second end of the leg 411 can be a free end, and a rotational force is applied to the leg 411, so that it can rotate relative to the first sleeve 420 to achieve the opening or closing of each leg 411.

[0104] When each support leg 411 is in an open state, the second end of each support leg 411 is located on the same plane and can be supported on a support surface, which can support the telescopic member 100; when each support leg 411 is in a folded state, the first main body 410 and the first sleeve 420 form a first columnar structure.

[0105] like Fig.13 and Fig.14 As shown, in another embodiment, the first sleeve 420 provided in the embodiment of the present application can be slidably installed on the telescopic member 100, and when the first sleeve 420 slides relative to the telescopic member 100 along the first direction, each support leg 411 can be opened or retracted.

[0106] Specifically, a connecting rod 510 is respectively arranged between the telescopic member 100 and each supporting leg 411, that is, the number of the connecting rods 510 is consistent with the number of the supporting legs 411, and each connecting rod 510 corresponds to a supporting leg 411; wherein one end of the connecting rod 510 is rotatably connected to the telescopic member 100, and the other end of the connecting rod 510 is rotatably connected to the supporting leg 411, one end of each supporting leg 411 is rotatably connected to the first sleeve 420, and when the first sleeve 420 slides relative to the telescopic member 100, the other end of the supporting leg 411 is opened or retracted relative to the telescopic member 100.

[0107] For example, one end of the connecting rod 510 is connected to the second end of the telescopic member 100, and the other end of the connecting rod 510 can be connected to the middle position of the support leg 411. When the first sleeve 420 slides relative to the telescopic member 100 along the first direction, the connecting rod 510 can be opened or retracted, thereby realizing the opening or retraction of each support leg 411.

[0108] Exemplarily, in the embodiment of the present application, the first sleeve 420 is provided with a sliding cavity 403, the telescopic member 100 is adapted to the sliding cavity 403, and the telescopic member 100 is slidably sleeved in the sliding cavity 403. More specifically, the inner wall of the sliding cavity 403 is convexly provided with a first protrusion 422, and the outer peripheral surface of the telescopic member 100 is provided with a first groove adapted to the first protrusion 422 (or, the telescopic member 100 is convexly provided with the first protrusion 422, and the inner wall of the sliding cavity 403 is provided with the first groove), the first protrusion 422 can be embedded in the first groove so that the first sleeve 420 is circumferentially fixed relative to the telescopic member 100, and when the first sleeve 420 slides along the telescopic member 100, the first protrusion 422 slides in the first groove.

[0109] like Figures 15 to 17 As shown, a first rotating portion 511 is provided at one end of the connecting rod 510, a second rotating portion 512 is provided at the other end, the support foot 411 is provided with a third rotating portion, and the telescopic member 100 is provided with a fourth rotating portion 104, wherein the first rotating portion 511 is rotationally matched with the third rotating portion, and the second rotating portion 512 is rotationally matched with the fourth rotating portion 104.

[0110] For example, the first rotating part 511 is a rotating protrusion and the third rotating part is a rotating groove, or the first rotating part 511 is a rotating groove and the third rotating part is a rotating protrusion; the second rotating part 512 is a rotating protrusion and the fourth rotating part 104 is a rotating groove, or the second rotating part 512 is a rotating groove and the fourth rotating part 104 is a rotating protrusion. This embodiment does not impose any restrictions on this, so that the connecting rod 510 can be rotatably connected to the telescopic member 100 and the support leg 411 respectively.

[0111] The end of the support leg 411 close to the first sleeve 420 is provided with a fifth rotating portion 411a, and the first sleeve 420 is provided with a sixth rotating portion 404, and the fifth rotating portion 411a is rotatably matched with the sixth rotating portion 404. The fifth rotating portion 411a is a rotating protrusion, and the sixth rotating portion 404 is a rotating groove, or the fifth rotating portion 411a is a rotating groove, and the sixth rotating portion 404 is a rotating protrusion, and the embodiment of the present application is not limited to this, so that the support leg 411 and the first sleeve 420 can be rotatably connected.

[0112] like Figures 18 to 27 As shown, the emergency device provided in the embodiment of the present application is a multifunctional emergency device, which is not limited to the above-mentioned cutter or life-saving hammer, and also includes a functional body 300, which can be set according to user needs. For example, the functional body 300 can be used as an emergency light (emergency lighting or emergency indicator light), or a life-saving signal transmitting device, or as a counterweight to enhance the hammering effect of the life-saving hammer, etc., and this embodiment does not limit this.

[0113] The embodiment of the present application is described by taking the functional body 300 as an emergency light as an example, that is, the functional body 300 includes a light-emitting component 330, the functional body 300 includes a retractable portion 300a and a non-retractable portion 300b, and the light-emitting component 330 is arranged in the non-retractable portion 300b.

[0114] Further, the functional body 300 is rotatably connected to the telescopic member 100, specifically, the functional body 300 is rotatably connected to the first end of the telescopic member 100. In this way, the telescopic member 100 can be extended to adjust the distance between the functional body 300 and the gripping member 400 along the first direction, and the irradiation angle of the emergency light can be adjusted.

[0115] Since the functional body 300 can rotate relative to the telescopic member 100, when the functional body 300 is in different positions relative to the telescopic member 100, the relative positions of the functional body 300 and the hammer 200 or the cutter are also different. Therefore, this embodiment is only described when the functional body 300 is in the first position and the second position.

[0116] In the embodiment of the present application, the functional body 300 is configured as a regular columnar structure or a rotary structure, which has a third central axis, and the length direction of the functional body 300 extends along the third central axis (preferably, the functional body 300 is a cylindrical structure); the telescopic member 100 is configured as a regular rod-shaped structure, which has a first central axis 102a, and the first central axis 102a is consistent with the first direction.

[0117] Exemplarily, when the functional body 300 rotates to the first position, the angle between the third center axis and the first center axis 102a is greater than or equal to 75° and less than or equal to 90°; the angle between the third center axis and the first center axis 102a can be 75°, 80°, 85°, 90°, etc. Preferably, when the functional body 300 is in the first position, the functional body 300 is perpendicular to the telescopic member 100, that is, the third center axis is perpendicular to the first center axis 102a.

[0118] When the functional body 300 rotates to the second position, the angle between the first center axis 102a and the third center axis is 0 to 15°, etc.; for example, the angle between the first center axis 102a and the third center axis is 0°, 5°, 10°, 15°, etc. Preferably, when the functional body 300 is in the second position, the extension direction of the functional body 300 and the telescopic member 100 is consistent, that is, the third center axis is collinear with the first center axis 102a.

[0119] Furthermore, in the embodiment of the present application, the emergency device integrates a functional body 300 and a hammering member 200. The hammering member 200 has a sharp hammering portion 220 to facilitate the hammering member 200 to hammer glass, etc. The hammering portion 220 is conical or pyramidal and has a second central axis. The hammering member 200 can be a rotating body around the second central axis.

[0120] The second central axis intersects the first central axis 102a, and the angle between the first central axis 102a and the second central axis is less than or equal to 90° and greater than or equal to 75°. For example, the angle between the first central axis 102a and the second central axis can be 90°, 85°, 80°, 75°, etc. Preferably, the hammer 200 is perpendicular to the telescopic rod 110, that is, the second central axis is perpendicular to the first central axis 102a.

[0121] In the embodiment of the present application, when the functional body 300 rotates to the first position, the functional body 300 and the hammer member 200 are respectively located on opposite sides of the telescopic member 100 , that is, along the second direction, the functional body 300 and the hammer member 200 are respectively located on both sides of the telescopic member 100 .

[0122] For example, the second center axis and the third center axis can be parallel, or the third center axis of the functional body 300 can be coaxial with the second center axis of the hammer 200. Such an arrangement can prevent the functional body 300 from hindering the hammer 200 from hammering, and when the hammer 200 hammers the glass, the functional body 300 can also provide hammering energy for the hammer 200, so that the hammering effect of the emergency device is better.

[0123] In the embodiment of the present application, when the functional body 300 rotates to the second position and the telescopic member 100 is in the retracted state, the retractable portion 300a can be accommodated in the accommodating cavity, and the non-accommodating portion 300b is located outside the accommodating cavity 401, that is, when the telescopic member 100 is in the retracted state, the light-emitting component 330 is still outside the accommodating cavity 401. Such a configuration can facilitate the storage of the above-mentioned functional components and the like in the accommodating cavity 401, and the light-emitting component 330 can emit light when the emergency device is in the retracted state, the handheld state, and the supporting state.

[0124] like Figure 28 to Figure 32 As shown, in the embodiment of the present application, the telescopic member 100 includes a telescopic rod 110 and a first connecting head 120. The first connecting head 120 is installed on the telescopic rod 110. The first connecting head 120 has a plug-in column 123. The first end of the telescopic rod 110 is provided with a plug-in hole 105. The first connecting head 120 is plugged into the plug-in hole 105 through the plug-in column 123, thereby realizing the first connecting head 120 being plugged into the first end of the telescopic rod 110.

[0125] The first connector 120 is used for rotationally connecting with the functional body 300. Accordingly, the functional body 300 is also provided with a second connector 312, and the second connector 312 is used for rotationally connecting with the first connector 120, so as to realize the rotational connection of the functional body 300 to the telescopic member 100.

[0126] The first connector 120 is used to install the action member, for example, the hammer member 200 is installed on the first connector 120. There is a rotation damping between the first connector 120 and the second connector 312 to lock the functional body 300 in a certain position, for example, the functional body 300 can be locked in the first position or the second position.

[0127] Exemplarily, the first connecting head 120 has a plurality of first connecting parts 121 arranged at intervals, the second connecting head 312 has a plurality of second connecting parts 312a arranged at intervals, the plurality of first connecting parts 121 and the plurality of second connecting parts 312a are arranged alternately, the first fastener 610 passes through the first connecting parts 121 and the second connecting parts 312a, and the first fastener 610 provides rotational damping between adjacent first connecting parts 121 and second connecting parts 312a.

[0128] For example, the number of first connection parts 121 is N, the number of second connection parts 312a is N-1, there is a first rotation cavity between two adjacent first connection parts 121, and each second connection part 312a is located between two adjacent first connection parts 121, that is, each second connection part 312a is located in the corresponding first rotation cavity.

[0129] The first fastener 610 is a threaded member, the head of the first fastener 610 is abutted against the first connecting portion 121 located on the first side of the first connecting head 120, and the threaded portion of the first fastener 610 is threadedly connected to the first connecting portion 121 located on the second side of the first connecting head 120, wherein the first side and the second side respectively refer to the opposite sides of the first connecting head 120 along the third direction.

[0130] The head of the first fastener 610 is provided with an adjustment portion, which may be a groove or a protrusion. The shape of the adjustment portion facilitates the user to adjust the tightness of the fastener using a screwdriver, thereby adjusting the friction damping force between the first connection portion 121 and the second connection portion 312a.

[0131] For example, a first gasket 620 and / or a damping ring are provided between at least one group of adjacent first connecting parts 121 and second connecting parts 312a, wherein the first gasket 620 can be made of a material with good wear resistance, such as metal, or engineering plastic, and the engineering plastic can be sintered steel; the damping ring can be made of a flexible material to enhance the rotational damping between the first connecting part 121 and the second connecting part 312a.

[0132] Furthermore, the second connector 312 is located in the retractable portion 300a of the functional body 300. When the functional body 300 is rotated to the second position and the telescopic member 100 is in a retracted state, the retractable portion 300a is accommodated in the accommodating cavity 401. Then, the first connector 120, the second connector 312, and the active member disposed on the first connector 120 are also accommodated in the accommodating cavity 401. In this state, the non-accommodating portion 300b is located outside the accommodating cavity 401, and the non-accommodating portion 300b and the gripping member 400 form a second columnar structure.

[0133] In order to facilitate the rotation of the functional body 300 to the first position so that the accommodating part can be accommodated in the accommodating cavity 401, the emergency device in the embodiment of the present application has a first opening 402 connected to the accommodating cavity 401. The first opening 402 can be an annular opening, and the first opening 402 cooperates with the outer peripheral surface of the accommodating part 300a so that the accommodating part 300a is embedded in the accommodating cavity 401.

[0134] Furthermore, a first step is provided at the transition between the storage portion and the non-storage portion 300 b , and when the storage portion is stored in the accommodating cavity 401 , the first step abuts against the end surface of the first opening 402 to limit the functional body 300 .

[0135] For example, the storage part and the non-storage part 300b have radial cross-sections of different sizes, and the radial size of the non-storage part 300b is larger than the radial size of the storage part to form a first step. When the retractable part 300a is accommodated in the accommodating cavity 401, the first step abuts against the end face of the first opening 402 to complete the positioning of the functional body 300 and the accommodating cavity 401.

[0136] like Figure 33 to Figure 36 See Fig. 20 The light-emitting component 330 provided in the embodiment of the present application includes a first light-emitting subcomponent 331 and a second light-emitting subcomponent 332 arranged in the non-storage portion 300b, and the non-storage portion 300b includes a side portion and two ends, wherein the first light-emitting subcomponent 331 is arranged on the side portion of the non-storage portion 300b, and the second light-emitting subcomponent 332 is arranged at the end of the non-storage portion 300b away from the telescopic member 100.

[0137] It should be noted that the lampshade of the first light-emitting subassembly 331 is made of a material that diffuses light, and the lampshade of the second light-emitting subassembly 332 is transparent, so that light does not diffuse after passing through the lampshade of the second light-emitting subassembly 332 .

[0138] Furthermore, the functional body 300 includes a movable part 321, a main shell 310, and a control circuit board 350 and a power supply 340 arranged in the main shell 310. The emergency light has a built-in power supply 340, and the power supply 340 can provide a certain counterweight for the emergency light. For example, when the functional body 300 is an emergency light, the weight of the functional body 300 is about 60g. Such a setting can increase the momentum of the hammer part 200 when hammering, thereby improving the hammering effect.

[0139] The power supply 340 is electrically connected to the light emitting assembly 330 and is used to supply power to the light emitting assembly 330. The movable member 321 is movably arranged in the retractable portion 300a, and the operation of the movable member 321 can control the on-off between the power supply 340 and the light emitting assembly 330. For example, the movable member 321 is slidably mounted on the fifth mounting surface of the retractable portion 300a, and the fifth mounting surface is convexly provided with a second connector 312, which can selectively slide to a third position and a fourth position. When the movable member 321 slides to the third position, the light emitting assembly 330 and the power supply 340 are electrically connected, and when the movable member 321 slides to the fourth position, the light emitting assembly 330 and the power supply 340 are disconnected.

[0140] The movable member 321 of the embodiment of the present application is movably disposed in the retractable portion 300a, and the movable member 321 is configured so that when the functional body 300 is rotated to the second position and the telescopic member 100 is in a retracted state, the movable member 321 is accommodated in the accommodating cavity 401. This arrangement can avoid accidental touch to turn on the emergency light, or effectively protect the movable member 321.

[0141] Correspondingly, the functional body 300 also includes a first switch 351, which is arranged on the control circuit board 350 and is located in the main shell 310. The first switch 351 is electrically connected to the power supply 340, and the first switch 351 is configured to control the on-off between the power supply 340 and the light-emitting component 330; the movable part 321 is adapted to the first switch 351, and operating the movable part 321 can activate the first switch 351 to control the on-off between the power supply 340 and the light-emitting component 330.

[0142] Exemplarily, the first switch 351 is electrically connected to the power supply 340, and the first switch 351 is electrically connected to the light emitting component 330. When the movable member 321 slides to the third position, the first switch 351 is in a closed state, and the light emitting component 330 is electrically connected to the power supply 340; when the movable member 321 slides to the fourth position, the first switch 351 is in an open state, and the light emitting component 330 is disconnected from the power supply 340 component.

[0143] For example, in one embodiment, the first switch 351 can be an automatically closed switch. When the movable member 321 slides to the third position, the first switch 351 automatically resets to the closed state; when the movable member 321 slides to the fourth position, the movable member 321 triggers the first switch 351 to put it in the open state.

[0144] Alternatively, in another embodiment, the first switch 351 may be an automatically disconnected switch. When the movable member 321 slides to the third position, the movable member 321 triggers the first switch 351 to be in a closed state. When the movable member 321 slides to the fourth position, the first switch 351 automatically resets to an open state.

[0145] Alternatively, in another embodiment, when the movable member 321 slides to the third position, the movable member 321 triggers the first switch 351 to put it in a closed state, and when the movable member 321 slides to the fourth position, the movable member 321 triggers the first switch 351 to put it in an open state.

[0147] Exemplarily, the first light-emitting subassembly 331 is disposed on the side of the main housing 310 and located in the non-storage portion 300b of the functional body 300. The first button 322 is disposed in the non-storage portion 300b of the main housing 310 and is used to control the light-emitting state of the first light-emitting subassembly 331.

[0148] Correspondingly, the control circuit board 350 is provided with a second switch 352, and the second switch 352 is electrically connected to the power supply 340 and the first light-emitting component 330 respectively, and the second switch 352 is adapted to the first button 322. Operating the first button 322 can activate the second switch 352, and pressing the first button 322 can trigger the second switch 352 so that the control circuit board 350350 sends a corresponding control signal to the first light-emitting subcomponent 331 to turn off or start the first light-emitting subcomponent 331.

[0149] For example, the first light-emitting subassembly 331 can emit an illuminating light or a flashing warning light source, and pressing the first button 322 can cause the first light-emitting subassembly 331 to emit a flashing warning light, or cause the first light-emitting subassembly 331 to emit an illuminating light, or cause the first light-emitting subassembly 331 to turn off. It should be understood that the main housing 310 is respectively provided with mounting ports for mounting the first button 322 and the first light-emitting subassembly 330, and the first light-emitting subassembly 331 and the first button 322 can be respectively snapped into the corresponding mounting ports.

[0150] On the basis of the above embodiments, the embodiments of the present application also provide a third switch 353 and a second button 323 for controlling the second light-emitting sub-component 332, the power supply 340 is used to supply power to the second light-emitting sub-component 332, the third switch 353 is electrically connected to the power supply 340, and the third switch 353 is used to control the light-emitting state of the second light-emitting sub-component 332; the second button 323 is arranged in the non-storage part 300b, the second button 323 is adapted to the third switch 353, and operating the second button 323 can activate the third switch 353 to control the light-emitting state of the second light-emitting sub-component 332.

[0151] Exemplarily, the second light-emitting subassembly 332 is disposed at the end of the main housing 310 and is located in the non-storage portion 300b of the functional body 300; the first light-emitting subassembly 331 and the second light-emitting subassembly 332 are arranged along the extension direction of the functional body 300. The second button 323 is disposed in the non-storage portion 300b of the main housing 310, and the second button 323 is used to control the light-emitting state of the second light-emitting subassembly 332, wherein the second button 323 and the first button 322 are close to each other and spaced apart, and such an arrangement can facilitate the control of the first light-emitting subassembly 331 and the second light-emitting subassembly 332.

[0152] Correspondingly, the control circuit board 350 is provided with a third switch 353, and the third switch 353 is electrically connected to the power supply 340 and the second light-emitting subassembly 330 respectively. The power supply 340 is used to supply power to the second light-emitting subassembly 330, and the third switch 353 is used to control the light-emitting state of the second light-emitting subassembly 330. The second button 323 is arranged in the non-storage part 300b, and the third switch 353 is adapted to the second button 323. Operating the second button 323 can activate the third switch 353 to control the light-emitting state of the second light-emitting subassembly 330. Specifically, pressing the second button 323 can trigger the third switch 353 so that the control circuit board 350350 sends a corresponding control signal to the second light-emitting subassembly 332 to turn off or start the second light-emitting subassembly 332.

[0153] For example, the second light-emitting subassembly 332 can emit an illuminating light, and pressing the second button 323 can cause the second light-emitting subassembly 332 to emit an illuminating light, or turn off the second light-emitting subassembly 332. It should be understood that the main housing 310 is respectively provided with mounting openings for mounting the second button 323 and the second light-emitting subassembly 330, and the second light-emitting subassembly 332 and the second button 323 can be respectively snapped into the corresponding mounting openings.

[0156] See also Figure 25 to Figure 27In the embodiment of the present application, the emergency device includes a functional body 300, a cutting piece 720 and a blocking piece 730. The cutting piece 720 and the blocking piece 730 are both arranged at the first end of the telescopic piece 100. The blocking piece 730 can be located on one side of the cutting piece 720 and can shield the cutting blade 721 of the cutting piece 720 to prevent the user from accidentally touching the cutting blade 721 and causing accidental injury, thereby reducing safety hazards.

[0157] Furthermore, when the telescopic member 100 is in the retracted state and the functional body 300 is in the second position, the retaining member 730 and the cutting member 720 are both accommodated in the accommodating cavity 401. Such an arrangement can reduce the volume of the emergency device and achieve miniaturization.

[0158] In the embodiment of the present application, the functional body 300 and the telescopic member 100 are rotatably connected through the first connector 120 and the second connector 312. The first connector 120 is inserted into the telescopic rod 110, and the second connector 312 is arranged in the storable part 300a of the functional body 300. The cutting member 720 is installed on the first connector 120, and the retaining member 730 is detachably installed on one side of the first connector 120, and a first gap 702 is formed between the retaining member 730 and the first connector 120. When the telescopic member 100 is in the contracted state, the first connector 120 and the second connector 312 are accommodated in the accommodating cavity 401.

[0159] The cutting piece 720 can be detachably mounted on the first connecting head 120, and the cutting blade 721 is located in the first gap 702, and the cutting blade 721 of the cutting piece 720 is set toward the blocking piece 730, and a cutting space is formed between the cutting blade 721 and the blocking piece 730. The emergency device has a second opening 704 connected to the cutting space. The strip to be cut can enter the cutting space through the second opening 704 and be cut by the cutting blade 721. For example, the strip can be a vehicle seat belt or the like.

[0160] For example, when the above-mentioned emergency device is used as a cutter, the emergency device also includes a second gripping portion 902, and the second gripping portion 902 can be configured as at least part of the telescopic rod 110 (that is, the second gripping portion 902 is located on the telescopic rod 110), and the second gripping portion 902 is close to the first end of the telescopic rod 110; or the second gripping portion 902 is configured with at least part of the gripping member 400 (that is, the second gripping portion 902 is located on the gripping member 400), which is not limited in this embodiment.

[0161] When the user holds the second grip 902 to cut the vehicle seat belt along the extension direction parallel to the telescopic member 100, the distance from the second grip 902 to the cutting member 720 remains unchanged, which may refer to that the second grip 902 is fixed relative to the cutting member 720, and the distance from the second grip 902 to the cutting member 720 remains constant; it may also refer to that the distance from the second grip 902 to the cutting member 720 can be changed, and when the cutting member 720 is used for cutting, the distance between the cutting member 720 and the second grip 902 is maximum or minimum, so that the distance from the second grip 902 to the cutting member 720 remains unchanged when the cutting member 720 is cutting.

[0162] Furthermore, the first connector 120 has a first installation cavity 701 communicating with the first gap 702, and the first installation cavity 701 is used to install a cutting member 720, and the cutting member 720 includes a first side and a second side arranged opposite to each other, wherein the first side of the cutting member 720 is arranged in cooperation with the first installation cavity 701, and the first side of the cutting member 720 is embedded in the first installation cavity 701. The second side of the cutting member 720 is configured as a cutting blade 721. The retaining member 730 abuts against the cutting member 720 to prevent the cutting member 720 from falling out of the first installation cavity 701.

[0163] In one embodiment, the cutting member 720 is detachably mounted on the retaining member 730, and the cutting blade 721 of the cutting member 720 is disposed toward the first connector 120, and a cutting space is formed between the cutting blade 721 and the first connector 120. In this solution, the retaining member 730 needs to have a certain thickness so that the first installation cavity 701 can be formed on the retaining member 730, which results in a larger volume of the retaining member 730, which is not conducive to miniaturization of the emergency device.

[0164] Preferably, the cutting member 720 is mounted on the first connector 120, and the cutting edge 721 of the cutting member 720 is disposed toward the retaining member 730. For example, the first connector 120 includes a third mounting surface and a fourth mounting surface that are disposed opposite to each other along the third direction, wherein the third mounting surface and the fourth mounting surface are used to mount the cutting member 720. The embodiment of the present application is described by taking the cutting member 720 being mounted on the third mounting surface as an example.

[0165] The retaining member 730 is detachably mounted on the third mounting surface, and the retaining member 730 is located on a side of the cutting member 720 away from the first connector 120, and a first gap 702 is formed between the retaining member 730 and the third mounting surface. The cutting member 720 is detachably mounted on the first connector 120, and the cutting blade 721 is located in the first gap 702. The third mounting surface is provided with a first mounting cavity 701, and the opening of the first mounting cavity 701 faces the first gap 702, so that the first side of the cutting member 720 is embedded in the first mounting cavity 701.

[0166] like Fig.37As shown, the retaining member 730 has a first retaining portion 731, and the first connector 120 has a second retaining portion 703, and the second retaining portion 703 is located on the third mounting surface. The first retaining portion 731 is retained by the second retaining portion 703 so that the retaining member 730 is circumferentially fixed relative to the first connector 120, the first retaining portion 731 is a protrusion, and the second retaining portion 703 is a groove, or the first retaining portion 731 is a groove, and the second retaining portion 703 is a protrusion.

[0167] Furthermore, a second groove 705d is provided on the side of the retaining member 730 facing the third mounting surface, and the second groove 705d is used to limit the cutting member 720. At least part of the cutting edge 721 of the cutting member 720 is embedded in the second groove 705d to prevent the cutting member 720 from escaping from the first gap 702.

[0168] The cutting blade 721 is arranged toward the retaining member 730, and a cutting space is formed therebetween. The emergency device has a second opening 704 connected to the cutting space, and the strip to be cut can enter the cutting space through the second opening 704 and be cut by the cutting blade 721. The cutting blade 721 is arranged obliquely along the third direction, wherein one end of the cutting blade 721 is arranged close to the third mounting surface, and the other end of the cutting blade 721 is arranged close to the wall surface where the second groove 705d is located (this wall surface is the inner surface of the retaining member 730 facing the third mounting surface), and the inclination angle of the cutting blade 721 is less than or equal to 45°. When the safety belt moves from the second opening 704 to the bottom wall of the first gap 702, it is convenient for the cutting blade 721 to cut the safety belt when it moves horizontally.

[0169] Furthermore, the opening direction of the second opening 704 is downward along the first direction, and the width of the second opening 704 is less than or equal to 6 mm to prevent human fingers and the like from accidentally entering the cutting space, thereby avoiding accidental injuries and reducing safety hazards.

[0170] Furthermore, along the third direction, the cutting member 720 has a first projection relative to the third mounting surface, and along the third direction, the blocking member 730 has a second projection relative to the third mounting surface, and the second projection covers the first projection, that is, the blocking member 730 can completely block the cutting member 720 in the third direction, and can also completely block the cutting member 720 in the second direction, wherein the second direction can be the thickness direction of the cutting member 720, that is, it is ensured that the cutting member 720 does not protrude from the blocking member 730 in the second direction. Such a configuration can prevent the user from causing accidental injury by the cutting member 720.

[0171] Furthermore, the emergency device provided in the embodiment of the present application integrates a cutting piece 720, a hammering piece 200 and a functional body 300, that is, the working piece includes a cutting piece 720 and a hammering piece 200. The hammering piece 200 and the cutting piece 720 are both arranged on the first connector 120 of the telescopic member 100, and when the functional body 300 rotates to the first position, the hammering piece 200 and the functional body 300 are respectively located on opposite sides of the first connector 120. When the functional body 300 rotates to the second position and the telescopic member 100 is in a contracted state, the retractable portion 300a of the functional body 300 is accommodated in the accommodating chamber 401, and the hammering piece 200, the cutting piece 720 and the first connector 120, the second connector 312 are all accommodated in the accommodating chamber 401.

[0172] The first connecting head 120 includes a first mounting surface and a second mounting surface which are relatively arranged along the second direction, wherein the first mounting surface is used to install the hammer member 200, and the second mounting surface is configured as a limiting surface. When the functional body 300 rotates to the first position, the telescopic member 100 abuts against the functional body 300, that is, the second mounting surface can abut against the storable part 300a, and the functional body 300 has a fifth mounting surface. The second connecting head 312 is protruding from the fifth mounting surface, that is, the second mounting surface abuts against the fifth mounting surface of the functional body 300 to limit the functional body 300. In other words, when the functional body 300 rotates to the first position, the telescopic member 100 abuts against the storable part 300a to limit the functional body 300.

[0173] When the second mounting surface in the embodiment of the present application abuts against the fifth mounting surface of the functional body 300, the functional body 300 is in the first position, for example, the third center axis of the functional body 300 is perpendicular to the first center axis 102a of the telescopic rod 110. With such a configuration, the functional body 300 can be quickly rotated to the first position so that the hammer 200 and the functional body 300 are on opposite sides of the telescopic rod 110, and the hammer 200 can then be used to quickly break the window.

[0174] Furthermore, the first connector 120 provided in the embodiment of the present application is provided with a first mounting protrusion 122 , the first mounting protrusion 122 is located on the first mounting surface, and at least a portion of the first mounting protrusion 122 is provided protruding from the first mounting surface.

[0175] For example, along the third direction, the end of the first mounting protrusion 122 is a gradually narrowing structure, which can be a truncated cone structure. The hammering member 200 includes a mounting body 210 and a hammering portion 220, the hammering portion 220 is located at one end of the mounting body 210, the hammering portion 220 has a certain taper, the angle between the cone surface generatrix and its second central axis is about 40°, and the ratio of the axial dimension of the hammering portion 220 to the axial dimension of the entire hammering member 200 is about 0.76; such a configuration can improve the hammering effect of the hammering portion.

[0176] Furthermore, in the embodiment of the present application, there is a first contact plane and a first center plane, the first center axis and the second center axis are both in the first center plane, the first center axis is the center axis of the telescopic member, the second center axis is the center axis of the hammer member, the first center axis is perpendicular to the second center axis, the first contact plane is perpendicular to the first center plane, the first contact plane contacts the hammering part 220, and the user lifts the first gripping part so that the first contact plane contacts the functional body. At this time, the angle between the first center axis and the first contact plane is 30° to 60° (or: the angle between the second center axis and the first contact plane is 60° to 30°); such a setting can avoid interference between the functional body and the hammering component when the hammering part is used to break the window, thereby improving the hammering effect.

[0177] Furthermore, the emergency device also has a first contact plane and a second center plane, the second center axis and the first axis define the second center plane, the functional body 300 is installed on the telescopic member 100 by rotating around the first axis, the second center axis is perpendicular to the first axis, the first contact plane is perpendicular to the second center plane, the first contact plane contacts the hammer part 220, the first contact plane can contact the first side of the first connector, the retaining member is installed on the second side of the first connector, and the first contact plane can contact the retaining member. When the first contact plane is perpendicular to the second center plane, the first contact plane contacts the hammer part, and the first contact plane contacts the first side of the first connector, the angle between the second center axis and the first contact plane is 45°-75°; when the first contact plane is perpendicular to the second center plane, the first contact plane contacts the hammer part, and the first contact plane contacts the retaining member, the angle between the second center axis and the first contact plane is 45°-75°; such a setting can avoid interference between the functional body and the hammer part when the hammer part is used to break the window, thereby improving the hammering effect.

[0178] In the embodiment of the present application, the installation body 210 is adapted to the second installation cavity 103, the installation body 210 is fixed in the second installation cavity 103, and at least part of the hammering portion 220 is exposed outside the second installation cavity 103. For example, the installation body 210 and the second installation cavity 103 are interference fit, the installation body 210 is inserted into the second installation cavity 103, and another example is that the installation body 210 is bonded into the second installation cavity 103.

[0179] On the basis of the above-mentioned embodiment, the emergency device provided in the embodiment of the present application further includes a protective cover 630, which can be put on the hammer member 200, and the protective cover 630 is flexibly connected to the telescopic member 100. With such a configuration, when the hammer member 200 is not in use, it is prevented from accidentally injuring a person by the hammer member 200, and the protective cover 630 is flexibly connected to the first connector 120, which not only facilitates the removal of the protective cover 630 from the hammer member 200, but also prevents the protective cover 630 from being separated from the telescopic member 100 and thus lost.

[0180] For example, the emergency device also includes a flexible connector 640, which is used to achieve a flexible connection between the protective cover 630 and the first connector 120. One end of the flexible connector 640 is connected to the protective cover 630, and the other end is connected to the first connector 120. The flexible connector 640 and the protective cover 630 are both made of polymer materials such as plastic. The flexible connector 640 is integrally connected to the protective cover 630, and the flexible connector 640 is detachably connected to the first connector 120.

[0181] The flexible connector 640 includes a flexible portion and a hoop 641 connected to the flexible portion. One end of the flexible portion is connected to the hoop 641, and the other end is connected to the protective sleeve 630. The hoop 641 is clamped on the first connector 120. The first connector 120 is provided with a second mounting protrusion 124, and the second mounting protrusion 124 is provided with a hoop groove 106. The hoop 641 is clamped in the hoop groove 106.

[0182] like Fig.38 and Fig.39 As shown, in another embodiment, the emergency device provided in the embodiment of the present application can be a life-saving hammer, which includes a hammering piece 200 and the above-mentioned functional body 300, wherein the hammering piece 200 and the functional body 300 are arranged at the first end of the telescopic piece 100, the telescopic piece 100 includes a telescopic rod 110 and a first connecting head 120, the first connecting head 120 is inserted into the end of the telescopic rod 110, and the functional body 300 is provided with a second connecting head 312, and is rotatably connected to the telescopic rod 110 through the second connecting head 312.

[0183] Furthermore, in this embodiment, the hammer member 200 can be integrated on the functional body 300. For example, the functional body 300 includes a retractable portion 300a and a non-retractable portion 300b. The hammer member 200 can be arranged in the retractable portion 300a and, together with the second connecting head 312, on the fifth mounting surface of the retractable portion 300a.

[0184] When the functional body 300 is in the first position, the hammering member 200 extends in the second direction and protrudes from the functional body 300, so as to ensure that the hammering member 200 can hammer the glass to break the window. When the functional body 300 rotates to the second position and the telescopic member 100 is in a retracted state, the hammering member 200 can be accommodated in the accommodating cavity 401, and the hammering member 200 extends in the first direction. Such a configuration can prevent the user from accidentally touching the hammering member 200 and causing accidental injury, thereby reducing safety hazards.

[0185] like Figure 40 to Figure 42 As shown, in another embodiment, the emergency device provided in the embodiment of the present application can be a life-saving hammer and / or a cutter, which includes a hammering member 200, a cutting member 720 and a functional body 300, wherein the hammering member 200, the cutting member 720 and the functional body 300 are arranged at the first end of the telescopic member 100, the telescopic member 100 includes a telescopic rod 110 and a first connecting head 120, the first connecting head 120 is inserted into the end of the telescopic rod 110, and the functional body 300 is provided with a second connecting head 312, and is rotatably connected to the telescopic rod 110 through the second connecting head 312.

[0186] Furthermore, in this embodiment, the hammering member 200 and the cutting member 720 can be integrated on the functional body 300. For example, the functional body 300 includes a retractable portion 300a and a non-retractable portion 300b. The hammering member 200 and the cutting member 720 can be arranged in the non-retractable portion 300b and located at the end of the non-retractable portion 300b away from the telescopic member 100, and along the second direction, the hammering member 200 and the cutting member 720 are relatively arranged on both sides of the functional body 300.

[0187] When the functional body 300 is in the second position, the emergency device is in use and can be used to break windows or cut seat belts.

[0188] Reference Figure 1-Figure 37 ,or Figure 38-Figure 39 ,or Figure 40-Figure 42 An embodiment of the present application proposes an emergency device for breaking glass by hammering, including a telescopic member 100 and a hammering member 200, wherein the hammering member 200 is installed on the telescopic member 100, and the emergency device has a first gripping portion 901 for a user to hold, and the telescopic member 100 can be extended to adjust the distance between the first gripping portion 901 and the hammering member 200; the hammering member 200 is installed on the telescopic member 100.

[0189] The emergency device has a telescopic member 100, which can adjust the distance between the first gripping portion 901 and the hammering member 200 by extension and retraction, so as to facilitate the use of the emergency device in different situations. For example, extending the telescopic member 100 can make the distance between the first gripping portion 901 and the hammering member 200 longer, so that the movement speed of the hammering member 200 is faster, thereby making the hammering effect of the hammering member 200 better. For another example, when the emergency device is used in a narrow space, the telescopic member 100 can be retracted to shorten the distance between the first gripping portion 901 and the hammering member 200, so as to facilitate the use of the emergency device in the narrow space.

[0190] It can be understood that when the first gripping portion 901 moves at the same angular velocity, the longer the distance between the first gripping portion 901 and the hammer 200 is, the faster the linear velocity of the hammer 200 is.

[0191] It can be understood that the extension of the telescopic member 100 can enable the hammer member 200 to hammer glass or the like that is farther away.

[0192] For example, the glass may be vehicle glass, house glass, or the like that hinders escape.

[0193] For example, the emergency device can be applied to vehicle safety, for example, the emergency device is used to break the glass of a vehicle with a hammer, and the vehicle can be a car, a train, etc.

[0194] Obviously, the emergency device can be used to hammer out objects other than glass.

[0195] For example, the emergency device can be applied to indoor safety, for example, the emergency device is used to hammer out glass of a house.

[0196] It can be understood that the telescopic member 100 is telescopic so that it presents different lengths. When the emergency device is not in use, the length of the telescopic member 100 can be retracted to make the overall occupied volume of the emergency device smaller, so as to facilitate the storage of the emergency device.

[0197] For example, the telescopic member 100 includes at least two telescopic joints 111 which are sequentially socketed. The telescopic member 100 includes a front telescopic joint and a rear telescopic joint. When the telescopic rod 110 of the telescopic member 100 is in an extended state, the front telescopic joint and the rear telescopic joint are respectively located at two ends of the telescopic rod 110. When the telescopic rod 110 is in a retracted state, the front telescopic joint can be retracted to the rear telescopic joint.

[0198] For example, the hammer 200 has a sharp hammer portion 220 to facilitate the hammer 200 to break the glass. For example, the hammer portion 220 is cone-shaped, such as a cone or a pyramid.

[0199] For example, refer to Figure 1 and Fig.25The telescopic member 100 has a first central axis 102a, and the telescopic member 100 includes a plurality of telescopic joints 111 which are sequentially connected, and each telescopic joint 111 is a stretching body extending along the first central axis 102a. The first central axis 102a is the geometric central axis of each telescopic joint 1111, and the telescopic member 100 surrounds the first central axis 102a, and the telescopic member 100 telescopes along the first central axis 102a; the hammer member 200 is a rotating body around a second central axis, and the second central axis intersects with the first central axis 102a. The angle between the first central axis 102a and the second central axis can be less than or equal to 90° and greater than or equal to 75°. For example, the angle between the first central axis 102a and the second central axis can be 90°, 85°, 80°, or 75°.

[0200] For example, a first center plane 102 passes through a first center axis 102 a of the telescopic member 100 , and the first center plane 102 passes through a hammer portion of the hammer member 200 .

[0201] Illustratively, the hammer 200 has a bar having a first end and a second end, and the first center plane 102 passes through the first end and the second end of the hammer 200 .

[0202] For example, the hammer 200 includes a mounting body 210 and a hammer portion 220 . The hammer portion 220 is located at one end of the mounting body 210 , and the first center plane 102 passes through the mounting body 210 and the hammer portion 220 .

[0203] For example, the hammer member 200 is a body of revolution about a second central axis, and the second central axis of the hammer member 200 is located on the first central plane 102 .

[0204] Preferably, the hammering member 200 is located at or close to one end of the telescopic member 100 to facilitate the hammering of the emergency device.

[0205] For example, the hammer member 200 is directly mounted on the telescopic member 100 . For example, the telescopic member 100 includes a telescopic rod 110 and a first connector 120 . The first connector 120 is mounted on one end of the telescopic rod 110 . The hammer member 200 is directly mounted on the first connector 120 .

[0206] For example, refer to Figures 38 to 42 The hammer member 200 is indirectly installed on the telescopic member 100 via an intermediate member. For example, the emergency device also includes a functional body 300, the functional body 300 is installed on the telescopic member 100, the hammer member 200 is installed on the functional body 300, the functional body 300 can be an emergency light, and the functional body 300 can also be a clamp for clamping an electronic terminal, and the electronic terminal can be a mobile phone, a tablet, etc.

[0207] For example, refer to Figure 1 , Fig. 22 , Fig.23 The hammer member 200 is installed on the telescopic member 100, and the telescopic member 100 is provided with a second installation cavity 103. The hammer member 200 is installed in the second installation cavity 103. The hammer member 200 includes a mounting body 210 and a hammering part 220. The hammering part 220 is located at one end of the mounting body 210. The mounting body 210 is adapted to the second installation cavity 103. The mounting body 210 is fixed to the second installation cavity 103, for example, the mounting body 210 is interference fit with the second installation cavity 103, and for another example, the mounting body 210 is bonded to the second installation cavity 103.

[0208] Specifically, the telescopic member 100 is provided with a first mounting protrusion 122, and the second mounting cavity 103 is provided on the first mounting protrusion 122. The telescopic member 100 includes a telescopic rod 110 and a first connector 120, the hammer member 200 is installed on the first connector 120, the first connector 120 is provided with the second mounting cavity 103, and the first connector 120 is provided with a first mounting protrusion 122. More specifically, referring to Fig.32 The first connecting head 120 has a first connecting portion 121 , and the first connecting portion 121 is protruded with a first mounting protrusion 122 .

[0209] In other examples, the hammer member 200 is integrally connected to the telescopic member 100 .

[0210] It should be understood that the first gripping portion 901 may be any grippable portion of the emergency device.

[0211] For example, the first gripping portion 901 is located on the telescopic member 100, and the telescopic member 100 includes a telescopic rod 110, and the telescopic rod 110 has a plurality of telescopic sections 111 which are sequentially socketed. The first gripping portion 901 is located on the second telescopic section 111b of the telescopic rod 110, and the hammering member 200 is fixed relative to the first telescopic section 111a of the telescopic rod 110. The first telescopic section 111a and the second telescopic section 111b can be adjacent telescopic sections, the first telescopic section 111a and the second telescopic section 111b can be non-adjacent telescopic sections, the first telescopic section 111a can be retracted to the second telescopic section 111b (or, the second telescopic section 111b can be retracted to the first telescopic section 111a). For example, the first gripping portion 901 is located at the tail telescopic section, and the hammering member is fixed relative to the first telescopic section. The first telescopic section 111a is the first telescopic section, and the second telescopic section 111b is the tail telescopic section, or the first telescopic section 111a is the tail telescopic section, and the second telescopic section 111b is the first telescopic section.

[0212] For example, the hammer member 200 is indirectly mounted on the first telescopic section 111 a , for example, the hammer member 200 is mounted on the first connecting head 120 , and the first connecting head 120 is mounted on the first telescopic section 111 a ; for example, the hammer member 200 is directly mounted on the first telescopic section 111 a .

[0213] For other examples, see Figure 1 and Figure 2 The emergency device also includes a gripping member 400 for easy gripping by the user. The gripping member 400 is installed on the telescopic member 100. The first gripping portion 901 is located on the gripping member 400. For example, the hammering member 200 is installed on the first telescopic section, and the gripping member 400 is installed on the tail telescopic section.

[0214] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 ,or Figure 38-Figure 39 The emergency device has a receiving chamber 401 surrounded by a first wall 421, and the telescopic member 100 is sleeved in the receiving chamber 401. The telescopic member 100 can be retracted to allow the hammer member 200 to be received in the receiving chamber 401. The advantage of such a configuration is that when the emergency device is not in use, the hammer member 200 is received in the receiving chamber 401, so that the emergency device occupies a smaller volume when received; the hammer member 200 is received in the receiving chamber 401 to avoid injuries caused by accidental touch by personnel; when the emergency device is not in use, the hammer member 200 is received in the receiving chamber 401 to avoid the influence of the external environment on the hammer member 200, such as the wear of the hammer member 200 caused by external impact.

[0215] It should be understood that referring to Figure 8 or Fig.39 The emergency device is provided with a first opening 402 communicating with the accommodating chamber 401 , so that the hammer 200 enters the accommodating chamber 401 through the first opening 402 .

[0216] For example, the telescopic member 100 includes a telescopic rod 110, and the telescopic rod 110 has a plurality of telescopic sections 111 which are sequentially socketed. The hammer member 200 is fixed relative to the first telescopic section 111a of the telescopic rod 110. The first telescopic section 111a can be retracted to the second telescopic section 111b. The first telescopic section 111a and the second telescopic section 111b can be adjacent or non-adjacent telescopic sections. During the process of the first telescopic section 111a being retracted to the second telescopic section 111b, the first wall 421 remains stationary relative to the second telescopic section 111b. For example, the first telescopic section 111a is the head telescopic section, and the second telescopic section 111b is the tail telescopic section.

[0217] For example, the accommodating cavity 401 is disposed on the gripping member 400 . The gripping member 400 has a first wall 421 . The first wall 421 is a part of the gripping member 400 .

[0218] For example, the accommodating cavity 401 is disposed in the first sleeve 420 . The first sleeve 420 has a first wall 421 . The first sleeve 420 is installed on the telescopic member 100 . The first wall 421 is a part of the first sleeve 420 .

[0219] For example, the accommodating cavity 401 is a columnar cavity, such as a cylindrical cavity, a prismatic cavity, etc.

[0220] For example, the shape of the first opening 402 is adapted to the cross section of the accommodating cavity 401 .

[0221] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further comprises a gripping member 400, the gripping member 400 has a first gripping portion 901, the gripping member 400 is mounted on the telescopic member 100, and the accommodating cavity 401 is disposed on the gripping member 400. The advantage of such a configuration is that the gripping member 400 is convenient for the user to hold the emergency device on the one hand, and is also used to accommodate the hammering member 200 on the other hand, so that the structure of the emergency device is compact.

[0222] For example, the gripping member 400 surrounds the telescopic member 100. For example, the telescopic member 100 includes a telescopic rod 110, and the telescopic rod 110 includes at least two telescopic joints 111. The gripping member 400 is mounted on the second telescopic joint 111b of the telescopic rod 110. The hammering member 200 is fixed relative to the first telescopic joint 111a of the telescopic rod 110. The first telescopic joint 111a and the second telescopic joint 111b can be adjacent telescopic joints, the first telescopic joint 111a and the second telescopic joint 111b can be non-adjacent telescopic joints, and the first telescopic joint 111a can be retracted to the second telescopic joint 111b. Preferably, the gripping member 400 is mounted on the rear telescopic joint, and the hammering member 200 is fixed relative to the front telescopic joint. The first telescopic joint 111a is the front telescopic joint, and the second telescopic joint 111b is the rear telescopic joint. The front telescopic joint and the rear telescopic joint are respectively located at the two ends of the telescopic rod 110.

[0223] For example, the tail telescopic section is located in the gripping member, and retracting the telescopic rod 110 can make all the telescopic sections 111 located in the gripping member.

[0224] For example, the holding member 400 radially protrudes relative to the telescopic member 100 to facilitate the user to hold the emergency device.

[0225] For example, the holding member 400 is a fixed structure, and the holding member 400 is fixed to the telescopic member 100 , or the holding member 400 is movably installed on the telescopic member 100 .

[0226] For example, the gripping member 400 is a structure having a plurality of changeable states, and the gripping member 400 is movably mounted on the telescopic member 100 .

[0227] For example, the gripping member 400 is provided with a first opening 402 communicating with the accommodating chamber 401 , so that the hammering member 200 enters the accommodating chamber 401 through the first opening 402 .

[0228] It should be understood that the shape and size of the grip 400 are convenient for the user to hold. For example, the grip 400 is a first columnar structure, and the first columnar structure can be prism-shaped, cylindrical, etc. For example, the first columnar structure is coaxial with the first central axis 102a of the telescopic member 100.

[0229] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further includes a gripping member 400 , the gripping member 400 has a first gripping portion 901 , and the gripping member 400 is mounted on the telescopic member 100 .

[0230] For example, the gripping member 400 includes a first sleeve 420 and a first body 410, and the first gripping portion 901 is located in the first sleeve 420, or the first gripping portion 901 is located in the first body 410, or the first gripping portion 901 is located in the first sleeve 420 and the first body 410. The first sleeve 420 is installed on the telescopic member 100 or the first body 410.

[0231] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device also includes a functional body 300, which is installed on the telescopic member 100. The emergency device includes at least three legs 411, and the at least three legs 411 can be opened or retracted. When the at least three legs 411 are opened, they can be supported on a supporting surface to support the telescopic member 100. The telescopic member 100 can be retracted to adjust the distance between the supporting surface and the functional body 300; when the at least three legs 411 are retracted, the at least three legs 411 form a first body 410. The gripping member 400 includes the first body 410, and the telescopic member 100 can be retracted to adjust the distance between the first body 410 and the functional body 300.

[0232] It should be understood that the telescopic member 100 is used to support both the functional body 300 and the hammer member 200, making the structure of the emergency device more compact; the telescopic member 100 is used to adjust the distance between the hammer member 200 and the first gripping portion 901, and to adjust the distance between the support surface and the functional body 300, making the structure of the emergency device compact. The three legs 411 can be used to support the functional body 300, and can be used for gripping when folded, making the structure of the emergency device compact.

[0233] It should be understood that when the emergency device needs to be used, the telescopic member 100 can be retracted and at least three legs 411 can be folded together, so that the emergency device occupies a small volume when stored, which is convenient for storage of the emergency device.

[0234] It should be understood that the telescopic member 100 can be extended and retracted so that the functional body 300 has different heights relative to the supporting surface.

[0235] It should be understood that when the user holds the first body 410 , the telescopic member 100 is telescoped so that the user's hand and the functional body 300 have different distances.

[0236] It should be understood that the greater the degree to which the at least three legs 411 are opened, the more stable the support provided by the at least three legs 411 is.

[0237] It should be understood that at least three legs 411 support the functional body 300 on a support surface, thereby freeing the user's hands and facilitating the user to use both hands to handle an emergency, making the emergency device more convenient to use.

[0238] For example, the functional body 300 may be an emergency light or a fixture for holding an electronic terminal. The emergency light may be an emergency indicator light or an emergency lighting lamp. The electronic terminal may be a mobile phone or a tablet.

[0239] For example, the legs 411 are rotatable relative to the telescopic member 100 , so that at least three legs 411 can be opened or retracted, for example, the legs 411 are directly rotatably connected to the telescopic member 100 .

[0240] For example, the support leg 411 is directly rotatably mounted on the telescopic member 100 , or the support leg 411 is indirectly rotatably mounted on the telescopic member 100 .

[0241] For example, the support surface may be the ground, a tabletop, or the like.

[0242] For example, the number of the legs 411 is 3, 4, 5, etc.

[0243] For example, when at least three legs 411 are folded together, there is a gap between two adjacent legs 411 .

[0244] In other examples, when at least three legs 411 are folded, there is no gap between two adjacent legs 411, and the first body 410 formed by folding at least three legs 411 is a columnar structure, for example, the first body 410 is a columnar structure coaxial with the first central axis 102a of the telescopic member 100.

[0245] For example, when at least three legs 411 are folded together, the legs 411 are moved closer to each other.

[0246] For example, when at least three legs 411 are folded together, the legs 411 are moved closer to each other, and the legs 411 are folded relative to the telescopic member 100 .

[0247] For example, the first body 410 itself can be held by a user, for example, the first body 410 is a columnar structure.

[0248] For example, the first body 410 can be held by a user after being combined with other parts of the emergency device. For example, the first body 410 can be held by a user after being combined with the first sleeve 420 .

[0249] By way of example, the first body 410 is a part of the grip 400 , or the first body 410 is the entire grip 400 .

[0250] For example, the telescopic member 100 includes a telescopic rod 110, which has a plurality of telescopic sections 111 that are sequentially connected, the functional body 300 is installed on the first telescopic section 111a, and the support leg 411 is installed on the second telescopic section 111b. For example, the first telescopic section 111a is the first telescopic section, and the second telescopic section 111b is the tail telescopic section.

[0251] For example, the functional body 300 is indirectly mounted on the first telescopic section 111 a , the functional body 300 is mounted on the first connecting head 120 , and the first connecting head 120 is mounted on the first telescopic section 111 a .

[0252] For example, the functional body 300 is close to or located at one end of the telescopic member 100 .

[0253] For example, the functional body 300 extends along a third straight line, and one end of the functional body 300 is mounted on the telescopic member 100 .

[0254] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device also includes at least three connecting rods 510, and the at least three connecting rods 510 correspond to at least three supporting legs 411 respectively. The emergency device also includes a first sleeve 420, and the first sleeve 420 is slidably mounted on the telescopic member 100. One end of each supporting leg 411 is rotatably mounted on the first sleeve 420. One end of the connecting rod 510 is rotatably mounted on the telescopic member 100, and the other end is rotatably mounted on the corresponding supporting leg 411. The first sleeve 420 slides relative to the telescopic member 100 to enable the at least three supporting legs 411 to be opened or retracted relative to the telescopic member 100.

[0255] It can be understood that the sliding of the first sleeve 420 can simultaneously open or close at least three legs 411, so that the emergency device can be quickly switched to different usage states.

[0256] It can be understood that the number of the connecting rods 510 is the same as the number of the supporting legs 411 .

[0257] By way of example, the first sleeve 420 , the telescopic member 100 , the support leg 411 , and the connecting rod 510 corresponding to the support leg 411 constitute a connecting rod slider mechanism.

[0258] For example, the telescopic member 100 includes a telescopic rod 110, the telescopic rod 110 has a plurality of telescopic sections 111 which are sequentially socketed, a first sleeve 420 is slidably mounted on a second telescopic section 111b, at least three legs 411 can be opened or retracted relative to the second telescopic section 111b, and the first sleeve 420 is always located at the second telescopic section 111b during the sliding process; preferably, the second telescopic section 111b is a tail telescopic section.

[0259] For example, refer to Figure 7When the supporting leg 411 is retracted into the telescopic member 100 , the connecting rod 510 is located between the supporting leg 411 and the telescopic member 100 .

[0260] For example, the support leg 411 is provided with a receiving groove, and when the support leg 411 is folded into the telescopic member 100 , the connecting rod 510 is received in the receiving groove of the support leg 411 .

[0261] For example, the telescopic member 100 is provided with a receiving groove, and when the supporting legs 411 are folded into the telescopic member 100 , the connecting rod 510 is received in the receiving groove of the telescopic member 100 .

[0262] For example, refer to Figure 8 , Fig.12 , Fig.17 Etc., the telescopic member 100 is sleeved on the first sleeve 420; specifically, the first sleeve 420 is provided with a sliding cavity 403, the telescopic member 100 is adapted to the sliding cavity 403, and the telescopic member 100 is slidably sleeved in the sliding cavity 403; more specifically, the first sleeve 420 is circumferentially fixed relative to the telescopic member 100, the inner wall of the sliding cavity 403 is convexly provided with a first protrusion 422, and the telescopic member 100 is provided with a first groove adapted to the first protrusion 422 (or, the telescopic member 100 is convexly provided with a first protrusion 422, and the inner wall of the sliding cavity 403 is provided with a first groove), the first protrusion 422 is in the first groove so that the first sleeve 420 is circumferentially fixed relative to the telescopic member 100, and when the first sleeve 420 slides along the telescopic member 100, the first protrusion 422 slides in the first groove.

[0263] For example, the first sleeve 420 is a columnar structure, and the first body 410 is a columnar structure. More preferably, the first sleeve 420 is adapted to the first body 410, and the first sleeve 420 and the first body 410 are integrally a first columnar structure.

[0264] For example, refer to Figures 12 to 17 Etc., a first rotating part 511 is provided at one end of the connecting rod 510, a second rotating part 512 is provided at the other end, a third rotating part is provided at the support foot 411, and a fourth rotating part 104 is provided at the telescopic member 100, wherein the first rotating part 511 is rotationally matched with the third rotating part, and the second rotating part 512 is rotationally matched with the fourth rotating part 104. For example, the first rotating part 511 is a rotary protrusion, and the third rotating part is a rotary groove, or the first rotating part 511 is a rotary groove, and the third rotating part is a rotary protrusion. For example, the second rotating part 512 is a rotary protrusion, and the fourth rotating part 104 is a rotary groove, or the second rotating part 512 is a rotary groove, and the fourth rotating part 104 is a rotary protrusion.

[0265] For example, the end of the support leg 411 close to the first sleeve 420 is provided with a fifth rotating portion 411a, the first sleeve 420 is provided with a sixth rotating portion 404, and the fifth rotating portion 411 is rotatably matched with the sixth rotating portion 404. The fifth rotating portion 411a is a rotary protrusion, and the sixth rotating portion 404 is a rotary groove, or the fifth rotating portion 411 is a rotary groove, and the sixth rotating portion 404 is a rotary protrusion.

[0266] In some other implementations, the emergency device does not include the connecting rod 510, one end of the support leg 411 is rotatably mounted on the first sleeve 420, the first sleeve 420 is fixedly mounted on the telescopic member 100, and the support leg 411 can be opened or retracted relative to the telescopic member 100, or one end of the support leg 411 is rotatably mounted on the telescopic member 100, and the support leg 411 can be opened or retracted relative to the telescopic member 100.

[0267] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The first sleeve 420 has a first wall 421 , and the first wall 421 surrounds and forms a receiving chamber 401 . The telescopic member 100 is sleeved in the receiving chamber 401 . When the telescopic member 100 contracts, the hammer member 200 can be received in the receiving chamber 401 .

[0268] It can be understood that the first sleeve 420 not only accommodates the hammer 200 but also allows the legs 411 to be opened or closed, so that the emergency device has a compact structure.

[0269] It should be understood that the first wall 421 of the accommodating cavity 401 is located in the first sleeve 420 , and the first wall 421 is the inner wall of the first sleeve 420 .

[0270] It should be understood that the accommodating chamber 401 includes a sliding chamber 403 , and the sliding chamber 403 is a part of the accommodating chamber 401 .

[0271] By way of example, a first opening 402 is provided at one end of the first sleeve 420 , and the first opening 402 is communicated with the accommodating cavity 401 .

[0272] For example, the telescopic member 100 includes a telescopic rod 110 , and the telescopic rod 110 includes at least two telescopic joints 111 . When the telescopic member 100 is in a retracted state, one end of the telescopic member 100 is located in the accommodating cavity 401 .

[0273] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The holding member 400 also includes a first sleeve 420, and the first sleeve 420 has a first wall body 421. The first wall body 421 surrounds and forms a receiving cavity 401. The receiving cavity 401 is formed by the first wall body 421. The telescopic member 100 is sleeved in the receiving cavity 401. The telescopic member 100 contracts to allow the hammer member 200 to be accommodated in the receiving cavity 401. The first sleeve 420 and the first main body 410 form a first columnar structure.

[0274] In other examples, the grip 400 does not include the first sleeve 420 .

[0275] It can be understood that the columnar structure can be a column or a nearly columnar structure.

[0276] For example, the first sleeve 420 and the first body 410 are both cylindrical, and the first columnar structure is cylindrical.

[0277] For example, the telescopic member 100 includes a telescopic rod 110, the telescopic rod 110 includes at least two telescopic joints 111, the first sleeve 420 is slidably installed on the second telescopic joint 111b, and at least three legs 411 are opened or retracted relative to the second telescopic joint 111b. When the at least three legs 411 are retracted in the second telescopic joint 111b, the first columnar structure surrounds the second telescopic joint 111b.

[0278] For example, when the telescopic member 100 is in a retracted state and at least three legs 411 are retracted in the telescopic member 100 , the telescopic member 100 is entirely located in the first columnar structure.

[0279] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 is rotatably installed on the telescopic member 100. The functional body 300 can be rotated to a first position relative to the telescopic member 100. When the functional body 300 is located at the first position relative to the telescopic member 100, the hammer member 200 and the functional body 300 are respectively located on opposite sides of the telescopic member 100. The telescopic member 100 can be telescoped to adjust the distance between the functional body 300 and the first gripping portion 901.

[0280] It can be understood that the hammering member 200 and the functional body 300 are located on opposite sides of the telescopic member 100 , so as to prevent the functional body 300 from hindering the hammering of the hammering member 200 .

[0281] It can be understood that the hammering member 200 and the functional body 300 are located on opposite sides of the telescopic member 100. When the hammering member 200 hammers the glass, the functional body 300 can also provide hammering energy for the hammering member 200, so that the hammering effect of the emergency device is better.

[0282] It can be understood that the functional body 300 is rotatably installed on the telescopic member 100 to facilitate adjustment of the use angle of the functional body 300. For example, when the functional body 300 is an emergency light, the functional body 300 can be rotated relative to the telescopic member 100 to adjust the illumination angle of the emergency light.

[0283] It should be understood that the first position may be a specific position point, or the first position may be a position range.

[0284] It should be understood that the functional body 300 can be maintained in the first position, for example, the functional body 300 is rotationally connected to the telescopic member 100 in a damped manner.

[0285] For example, the hammer member 200 is close to or located at one end of the telescopic member 100 , and the functional body 300 is located at or close to one end of the telescopic member 100 .

[0286] For example, the functional body 300 extends along a third straight line, and the telescopic member 100 extends along a first straight line (the telescopic member telescopes in a direction parallel to the first straight line). When the functional body 300 is in the first position of the telescopic member 100, the angle between the third straight line and the first straight line is greater than or equal to 75° and less than or equal to 90°. The angle between the third straight line and the first straight line is 75°, 80°, 85°, 90°, etc. For example, the functional body 300 is perpendicular to the telescopic member 100.

[0287] For example, the telescopic member 100 has a first central axis 102a, and the first straight line is parallel to the first central axis 102a.

[0288] For example, the non-storage portion 300 b of the functional body 300 is in a columnar structure. When the functional body 300 is in the first position of the telescopic member 100 , the axis of the non-storage portion 300 b intersects with the first central axis 102 a of the telescopic member 100 .

[0289] It can be understood that the axis of the non-storage portion 300b is parallel to the third straight line.

[0290] For example, the functional body 300 extends along a third straight line, and the telescopic member 100 extends along a first straight line. When the functional body 300 is in the second position of the telescopic member 100, the angle between the first straight line and the third straight line is 0 to 15°, etc., and the angle between the first straight line and the third straight line is 0°, 5°, 10°, 15°, etc., such as the functional body 300 is along the extension direction of the telescopic member 100.

[0291] For example, the non-storage portion 300b of the functional body 300 is a columnar structure, and when the functional body 300 is in the second position of the telescopic member 100, the axis of the non-storage portion 300b is coaxial with the first central axis 102a of the telescopic member 100. The axis of the non-storage portion 300b is the third central axis of the functional body 300.

[0292] It can be understood that the telescopic member 100 can be extended and retracted to adjust the distance between the user's hand and the functional body 300 . For example, the telescopic member 100 can be extended and retracted to adjust the height of the functional body 300 .

[0293] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37The telescopic member 100 includes a telescopic rod 110 and a first connecting head 120, the first connecting head 120 is installed at one end of the telescopic rod 110; the hammer member 200 is installed on the first connecting head 120, and the functional body 300 is rotatably installed on the first connecting head 120. When the functional body 300 is located at the first position relative to the telescopic member 100, the hammer member 200 and the functional body 300 are respectively located on opposite sides of the first connecting head 120.

[0294] It can be understood that the telescopic member 100 includes a telescopic rod 110 and a first connecting head 120, which facilitates the manufacture of the telescopic member 100 and the installation of the hammer member 200 and the functional body 300; for example, the telescopic rod 110 is made of a hollow metal pipe, and the first connecting head 120 is made of metal.

[0295] It can be understood that the hammer 200 and the functional body 300 are both arranged on the first connecting head 120, so that the structure of the emergency device is more compact.

[0296] For example, refer to Fig.29 The first connecting head 120 is fixedly installed on the first telescopic joint 111a. The first connecting head 120 has a plug-in column 123. The first telescopic joint 111a has a plug-in hole 105. The plug-in column 123 and the plug-in hole 105 are interference fit. The first telescopic joint 111a is the first telescopic joint.

[0297] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device has a receiving cavity 401 surrounded by a first wall 421 , and the telescopic member 100 is sleeved in the receiving cavity 401 . The telescopic member 100 contracts to allow the first connector 120 to be received in the receiving cavity 401 .

[0298] It can be understood that the first connector 120 is accommodated in the accommodation cavity 401, so that the emergency device has a compact structure when stored.

[0299] It can be understood that the first connector 120 can be accommodated in the accommodation cavity 401 through the first opening 402 .

[0300] It can be understood that the hammer 200 is accommodated in the accommodation cavity 401 through the first opening 402 .

[0301] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37The telescopic member 100 extends in a direction parallel to the first straight line, and has a first plane parallel to the first straight line. When the functional body is located at the first position relative to the telescopic member, the first plane is perpendicular to the third straight line. The orthographic projection of the hammering member 200 on the first plane is the first projection, and the orthographic projection of the functional body 300 on the first plane is the second projection, and the second projection includes the first projection. The advantage of such a setting is that the functional body 300 is facing the hammering member 200, so that the hammering effect of the emergency device is better.

[0302] It can be understood that the telescopic member 100 telescopes along a direction parallel to the first straight line.

[0303] For example, when the functional body 300 is in the first position of the telescopic member 100, the angle between the third straight line and the first straight line is greater than or equal to 75° and less than or equal to 90° (for example, the angle between the third straight line and the first straight line is 75°, 80°, 85°, 90°, etc.), and the first plane is perpendicular to the third straight line.

[0304] Preferably, when the functional body 300 is in the first position of the telescopic member 100 , the third straight line is perpendicular to the first straight line.

[0305] For example, the functional body 300 is rotatably installed on the telescopic member 100 around a first axis, and the angle between the first axis and the first straight line is greater than or equal to 75° and less than or equal to 90°. For example, the angle between the first axis and the first straight line is 75°, 80°, 85°, 90°, etc.

[0306] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 can be rotated to a second position relative to the telescopic member 100. The emergency device has a accommodating cavity 401 surrounded by a first wall 421, and the telescopic member 100 is sleeved in the accommodating cavity 401; the functional body 300 has a retractable portion 300a, and the retractable portion 300a is rotatably installed on the telescopic member 100. When the functional body 300 is in the second position relative to the telescopic member 100, the telescopic member 100 is contracted so that the retractable portion 300a can be accommodated in the accommodating cavity 401.

[0307] It can be understood that the retractable portion 300a can be retracted into the accommodating cavity 401, so that the emergency device has a compact structure in the retracted state.

[0308] It can be understood that the retractable portion 300 a is rotatably mounted on the telescopic member 100 so that the functional body 300 is rotatably mounted on the telescopic member 100 .

[0309] Illustratively, the outer periphery of the storable portion 300 a is adapted to fit with the first opening 402 .

[0310] For example, the second position may be a position point, or a position range.

[0311] For example, when the functional body 300 is in the second position of the telescopic member 100 , the retractable portion 300 a is a portion of the functional body 300 close to the telescopic member 100 .

[0312] By way of example, the storable portion 300 a may be a portion of the functional body 300 , or the storable portion 300 a may be the entirety of the functional body 300 .

[0313] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further comprises a functional body 300, which is mounted on the telescopic member 100. The functional body 300 has a retractable portion 300a, which is mounted on the telescopic member 100. The retractable portion 300a can be retracted into the accommodating cavity 401 by contracting the telescopic member 100. The telescopic member 100 can adjust the distance between the first gripping portion 901 and the functional body 300. The advantage of such a configuration is that the structure of the emergency device is more compact when it is stored, and the telescopic member 100 can adjust the distance between the first gripping portion 901 and the functional body 300 when it is used.

[0314] For example, the functional body 300 is fixedly mounted on the telescopic member 100 .

[0315] For example, the functional body 300 is rotatably mounted on the telescopic member 100 .

[0316] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 is rotatably mounted on the telescopic member 100, and the storable portion 300a is rotatably mounted on the telescopic member 100. The functional body 300 can be rotated to a second position relative to the telescopic member 100. When the functional body 300 is at the second position relative to the telescopic member 100, the telescopic member 100 is contracted so that the storable portion 300a can be accommodated in the accommodating cavity 401.

[0317] The advantage of the above arrangement is that the functional body 300 can be rotatably mounted on the telescopic member 100 to adjust the use angle of the functional body 300, and the retractable portion 300a can be retracted into the accommodating cavity 401, so that the emergency device has a more compact structure in the retracted state.

[0318] It should be understood that the retractable portion 300 a is rotatably mounted on the telescopic member 100 so that the functional body 300 is rotatably mounted on the telescopic member 100 .

[0319] In some other implementations, other parts of the functional body except the storable part 300 a are rotatably mounted on the telescopic member 100 .

[0320] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37The storable part 300a includes a second connecting head 312, which is rotatably connected to the telescopic member 100 so that the functional body 300 is rotatably installed on the telescopic member 100; the telescopic member 100 includes a telescopic rod 110 and a first connecting head 120, the first connecting head 120 is installed at one end of the telescopic rod 110, the second connecting head 312 is rotatably connected to the first connecting head 120, and when the storable part 300a is accommodated in the accommodating cavity 401, the first connecting head 120 is accommodated in the accommodating cavity 401.

[0321] It can be understood that both the first connector 120 and the second connector 312 can be accommodated in the accommodating cavity 401, so that the structure of the emergency device is more compact when in the storage state.

[0322] By way of example, the second connecting head 312 is connected to the first connecting head 120 in a damped rotational connection, and the emergency device further includes a first fastener 610, which passes through the first connecting head 120 and the second connecting head 312 so that the second connecting head 312 is connected to the first connecting head 120 in a damped rotational connection; by way of example, the first fastener 610 can be a threaded member, a rivet, etc.

[0323] For example, the first connecting head 120 has a plurality of first connecting parts 121 arranged at intervals, the second connecting head 312 has a plurality of second connecting parts 312a arranged at intervals, the plurality of first connecting parts 121 and the plurality of second connecting parts 312a are arranged alternately, the first fastener 610 passes through the first connecting parts 121 and the second connecting parts 312a, and the first fastener 610 provides rotational damping between adjacent first connecting parts 121 and second connecting parts 312a.

[0324] Specifically, the number of the first connection parts 121 is N, the number of the second connection parts 312a is N-1, a first rotation cavity is provided between two adjacent first connection parts 121, each second connection part 312a is located between two adjacent first connection parts 121, that is, each second connection part 312a is located in the corresponding first rotation cavity, the first fastener 610 is a threaded member, the head of the first fastener 610 abuts against the first connection part 121 located on the first side of the first connection head 120, and the threaded part of the first fastener 610 is threadedly connected with the first connection part 121 located on the second side of the first connection head 120, wherein the first side and the second side refer to the opposite sides of the first connection head 120, respectively. The head of the first fastener 610 is provided with an adjustment part, which can be a groove or a protrusion, and the shape of the adjustment part is convenient for the user to use a screwdriver to adjust the fastening degree of the fastener, thereby adjusting the friction damping force between the first connection part 121 and the second connection part 312a.

[0325] For example, at least one first gasket 620 is provided between the first connector and the second connector. The first gasket 620 can be made of a material with good wear resistance, such as metal or engineering plastic. The engineering plastic can be sintered steel. A first gasket 620 is provided between at least one set of adjacent first connecting portions 121 and second connecting portions 312a.

[0326] By way of example, the number of the first connection portions 121 is three, and the number of the second connection portions 312a is two.

[0327] Furthermore, the telescopic member 100 has a first central axis 102a, and a first central plane 102 passes through the first central axis 102a of the telescopic member 100. The first central plane 102 passes through the hammering portion 220 of the hammering member 200, wherein a first connecting portion 121 intersects with the first central plane 102, and the hammering member 200 is installed on the first connecting portion 121.

[0328] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device also includes a gripping member 400, the gripping member 400 has a first gripping portion 901, the gripping member 400 is installed on the telescopic member 100, the accommodating cavity 401 is provided in the gripping member 400, and the gripping member 400 presents a first columnar structure; the functional body 300 also includes a non-storage portion 300b connected to the storable portion 300a, when the storable portion 300a is accommodated in the accommodating cavity 401, the non-storage portion 300b is located outside the accommodating cavity 401, the telescopic member 100 is located in the gripping member 400, and the non-storage portion 300b and the gripping member 400 form a second columnar structure.

[0329] It can be understood that the holding piece 400 is convenient for the user to hold the emergency device, and is also used to store structures such as the hammer 200, so that the emergency device has a more compact structure when stored.

[0330] It can be understood that when the storable portion 300a is located in the accommodating cavity 401, the telescopic member 100 is located in the holding member 400, so that the emergency device has a compact structure when stored.

[0331] It can be understood that the non-storage portion 300b and the gripping member 400 integrally form a second columnar structure, so that the emergency device occupies a small volume and is easy to store.

[0332] For example, the gripping member 400 is a fixed structure fixed to the telescopic member 100 , and the accommodating cavity 401 is fixed relative to the telescopic member 100 .

[0333] For example, the gripping member 400 is a movable structure relative to the telescopic member 100 , and the accommodating cavity 401 is movable relative to the telescopic member 100 , for example, the accommodating cavity 401 is rotatable relative to the telescopic member 100 , or the accommodating cavity 401 slides relative to the telescopic member 100 .

[0334] For example, the first columnar structure may be a column or a nearly columnar structure, for example, the first columnar structure may be a prism, a cylinder, or the like.

[0335] For example, the second columnar structure may be a column or a nearly columnar structure, for example, the second columnar structure may be a prism, a cylinder, or the like.

[0336] For example, the cross-section of the storable portion 300a is larger than that of the non-storable portion, and the transition between the storable portion 300a and the non-storable portion 300b has a first step. When the storable portion 300a is stored in the accommodating cavity 401, the non-storable portion 300b abuts against the gripping piece 400, that is, the non-storage portion 300b abuts against the end wall of the first wall 421.

[0337] For example, the first columnar structure is coaxial with the first central axis 102 a of the telescopic member 100 .

[0338] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 When the storable portion 300a is stored in the accommodating cavity 401, the non-storable portion 300b abuts against the end wall of the first wall 421. The advantage of this arrangement is that when the non-storable portion 300b abuts against the end wall of the first wall 421, the storable portion 300a is just stored in the accommodating cavity 401, thereby facilitating the storage of the storable portion 300a.

[0339] For example, the accommodating cavity 401 is connected to the end of the grip 400 , and the end wall of the first wall 421 is located at the end of the grip 400 . When the accommodating portion 300a is accommodated in the accommodating cavity 401 , the non-accommodating portion 300b abuts against the end of the grip 400 .

[0340] For example, the accommodating cavity 401 is connected to the end of the first sleeve 420 , and the end wall of the first wall body 421 is located at the end of the first sleeve 420 . When the accommodating portion 300a is accommodated in the accommodating cavity 401 , the non-accommodating portion 300b abuts against the end of the first sleeve 420 .

[0341] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 further includes a non-storage portion 300b connected to the storable portion 300a. The functional body 300 is an emergency light. The functional body 300 has a light-emitting component 330, and the light-emitting component 330 is arranged in the non-storage portion 300b. The advantage of such a setting is that when the emergency device is in the storage state, the light-emitting component 330 of the emergency light can still emit light, so that the emergency device can still be used as an emergency indicator light or emergency lighting lamp in the storage state.

[0342] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 is an emergency light. The functional body 300 has a light-emitting component 330, a power supply 340 and a movable part 321. The movable part 321 is movably arranged in the retractable part 300a. The movable part 321 can be in a third position and a fourth position relative to the retractable part 321. When the movable part 321 is in the third position, the light-emitting component 330 and the power supply 340 are electrically connected. When the movable part 321 is in the fourth position, the light-emitting component 330 and the power supply 340 are disconnected.

[0343] It can be understood that when the storable part 300a is stored in the accommodating cavity 401, the movable part 321 is also stored in the accommodating cavity 401, thereby preventing external objects from touching the movable part 321 when the emergency device is in the stored state, or when the emergency device is stored for a long time, thereby preventing or reducing the influence of external fog and dust from entering the functional body 300 through the movable part 321.

[0344] For example, the functional body 300 has a main shell 310, and the movable member 321 is movably arranged on the main shell 310, for example, the movable member 321 is slidably or rotatably arranged on the main shell 310. It should be understood that a part of the main shell 310 is the retractable part 300a.

[0345] For example, the movable member 321 is slidably mounted on the retractable portion 300 a , or the movable member 321 is rotatably mounted on the retractable portion 300 a .

[0346] For example, the movable member 321 is located at a portion of the main housing 310 close to the telescopic member 100 , and the movable member 321 is located at a portion of the storable portion 300 a close to the telescopic member 100 .

[0347] By way of example, the movable member 321 is located on the surface of the main housing 310 .

[0348] For example, the third position may be a position point or a position range, and the fourth position may be a position point or a position range.

[0349] For example, the functional body 300 has a first switch 351, which is electrically connected to the power supply 340 and the light-emitting component 330; when the movable part 321 moves to the third position, the first switch 351 is in a closed state, and the light-emitting component 330 is electrically connected to the power supply component 340; when the movable part 321 moves to the fourth position, the first switch 351 is in an open state, and the light-emitting component 330 is electrically connected to the power supply component 340. For example, the first switch 351 is an automatically closed switch, and when the movable member 321 moves to the third position, the first switch 351 automatically resets to the closed state, and when the movable member 321 moves to the fourth position, the movable member 321 touches the first switch 351 to put it in an open state; or, the first switch 351 is an automatically opened switch, and when the movable member 321 moves to the third position, the movable member 321 touches the first switch 351 to put it in a closed state, and when the movable member 321 moves to the fourth position, the first switch 351 automatically resets to an open state; or, when the movable member 321 moves to the third position, the movable member 321 touches the first switch 351 to put it in a closed state, and when the movable member 321 moves to the fourth position, the movable member 321 touches the first switch 351 to put it in an open state.

[0350] For example, the emergency light can be an emergency indicator light or an emergency lighting light. The emergency indicator light emits warning, danger indication, direction indication and other indicator lights. For example, when a vehicle breaks down or a traffic accident occurs, the emergency light can emit a flashing warning light source to alert vehicles or pedestrians behind the road. The emergency light can emit illuminating light. For example, at night or when the light is dim during the day, the emergency lighting light is used for illumination.

[0351] Specifically, the light-emitting assembly 330 includes a first light-emitting subassembly 331 and a second light-emitting subassembly 332. The functional body 300 extends along the third straight line. The first light-emitting subassembly 331 is arranged at the side of the functional body 300, and the second light-emitting subassembly 332 is arranged at the end of the functional body 300. The emergency light is provided with a first button 322 and a second button 323. The first button 322 is installed on the main housing 310, and the second button 323 is installed on the main housing 310. The first button 322 is used to control the first light-emitting subassembly 331, and the second button 323 is used to control the second light-emitting subassembly 332. For example, the first light-emitting subassembly 331 can emit an illuminating light or a flashing warning light source. Pressing the first button 322 can cause the first light-emitting subassembly 331 to emit a flashing warning light, or cause the first light-emitting subassembly 331 to emit an illuminating light, or cause the first light-emitting subassembly 331 to turn off. For example, the second light emitting subassembly 332 emits an illuminating light, and pressing the second button 323 can cause the second light emitting subassembly 332 to emit an illuminating light, or turn off the second light emitting subassembly 332.

[0352] More specifically, the emergency light also includes a control circuit board 350, which is electrically connected to the first light-emitting sub-component 331, and the control circuit board 350 is electrically connected to the second light-emitting sub-component 332. Pressing the first button 322 can cause the control circuit board 350 to send a corresponding control signal to the first light-emitting sub-component 331, or pressing the first button 322 can cause the first light-emitting sub-component 331 to be extinguished or started, and pressing the second button 323 can cause the control circuit board 350 to extinguish or start the second light-emitting sub-component 332.

[0353] For example, the control circuit board 350 is provided with a second switch 352 and a third switch 353, and the second switch 352 and the third switch 353 correspond to the first button 322 and the second button 323 respectively. Pressing the first button 322 can trigger the second switch 352 so that the control circuit board 350 sends a corresponding control signal to the first light-emitting sub-component 331. Pressing the first button 322 can trigger the second switch 352 so that the first light-emitting sub-component 331 is turned off or started. Pressing the second button 323 can trigger the third switch 353 so that the first light-emitting sub-component 331 is turned off or started.

[0354] By way of example, the first switch 351 , the second switch 352 , and the third switch 353 are all mounted on the control circuit board 350 .

[0355] For example, the first light-emitting subassembly 331 is mounted on the side of the main housing 310, and the second light-emitting subassembly 332 is mounted on the end of the main housing 310. The first light-emitting subassembly 331 is clamped with the side of the main housing 310, and the second light-emitting subassembly 332 is clamped with the end of the main housing 310.

[0356] For example, the main shell 310 is also equipped with a charging interface 354 and an interface protection member 324. The interface protection member 324 is flexibly connected to the main shell 310. The charging interface 354 can be a USB, a lighning interface, etc. The interface protection member 324 is used to protect the charging interface 354 to prevent dust from entering the charging interface 354 when the emergency light is not charging.

[0357] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device has a first opening 402 communicating with the accommodating cavity 401 , and the accommodating portion 300a is accommodated in the accommodating cavity 401 through the first opening 402 ; when the accommodating portion 300a is accommodated in the accommodating cavity 401 , the outer periphery of the accommodating portion 300a cooperates with the inner periphery of the first wall 421 .

[0358] The advantage of such a configuration is that, on the one hand, the retractable portion 300a can be retracted into the accommodating cavity 401 through the first opening 402, and on the other hand, after the retractable portion 300a is retracted into the accommodating cavity 401, the retractable portion 300a cooperates with the first wall 421, thereby reducing the shaking of the retractable portion 300a relative to the accommodating cavity 401. The shaking of the retractable portion 300a relative to the accommodating cavity 401 may be caused by the bending deformation of the telescopic member 100, or the rotation of the retractable portion 300a relative to the telescopic member 100, etc.

[0359] For example, the outer cross-sectional shape and size of the storable portion 300 a match the inner cross-sectional shape and size of the first wall 421 .

[0360] For example, the outer cross-sectional shape and size of the storable portion 300 a are adapted to the first opening 402 .

[0361] For example, the outer periphery of the retractable portion 300 a and the inner periphery of the first wall 421 may be matched in a clearance fit, an interference fit, a transition fit, or the like.

[0362] For example, the cross-section of the outer periphery of the storable portion 300 a is circular or polygonal, and the cross-section of the inner periphery of the first wall 421 is circular or polygonal.

[0363] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device has a receiving cavity 401 surrounded by a first wall 421, and the telescopic member 100 is sleeved in the receiving cavity 401. The emergency device also includes a cutting member 720 for cutting the vehicle seat belt. The cutting member 720 is installed on the telescopic member 100. The telescopic member 100 can be retracted to allow the cutting member 720 to be accommodated in the receiving cavity 401.

[0364] The advantage of such a configuration is that when the emergency device is not in use, the cutting member 720 can be accommodated in the accommodating cavity 401, thereby preventing the cutting member 720 from accidentally injuring someone.

[0365] It will be appreciated that the cutting member 720 may also be used to cut vehicle seat belts and the like.

[0366] For example, the telescopic member 100 has a plurality of telescopic sections 111 that are connected in sequence, the cutting member 720 is fixed relative to the first telescopic section 111a, and the cutting member 720 is directly or indirectly mounted on the first telescopic section 111a, and the first telescopic section 111a can be the first telescopic section. The cutting member 720 is indirectly mounted on the first telescopic section, referring to Figure 2 The cutting member 720 is mounted on the first connecting head 120, and the first connecting head 120 is mounted on the first telescopic section 111a. Figure 40-Figure 42The cutting piece 720 is installed on the functional body 300, the functional body 300 is installed on the first connecting head 120, and the first connecting head 120 is installed on the first telescopic section 111a.

[0367] For example, the cutting member 720 is indirectly mounted on the telescopic member, for example, referring to Figure 40-Figure 42 The cutting piece 720 is installed on the functional body 300 , and the functional body 300 is installed on the telescopic piece 100 .

[0368] It can be understood that the telescopic member 100 is telescopic, so that the cutting member 720 can be used to cut the vehicle safety belt at a long distance.

[0369] For example, the emergency device has a second grip 902, and the user grips the second grip 902 to make the cutting member 720 cut the safety belt, and the second grip 902 is located at the first telescopic section 111a, and the first telescopic section 111a can be a first telescopic section. Alternatively, the telescopic member 100 also has a second telescopic section 111b, and the second telescopic section 111b is an adjacent or non-adjacent telescopic section to the first telescopic section 111a. When the first telescopic section 111a is extended to the maximum distance relative to the second telescopic section 111b, the second grip 902 is located at the second telescopic section 111b, and the second telescopic section 111b can be a tail telescopic section.

[0370] For example, the emergency device has a gripping member 400 , which is mounted on the telescopic member 100 . When the distance between the gripping member 400 and the cutting member 720 is the largest, the gripping member 400 has a second gripping portion 902 .

[0371] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further includes a cutting piece 720 for cutting the vehicle safety belt. The emergency device includes a third body 710 , and the cutting piece 720 is detachably mounted on the third body 710 .

[0372] The advantage of the above arrangement is that the cutting member 720 can be detachably mounted on the third body 710, so that the cutting member 720 can be replaced in time when the cutting member 720 is worn or damaged.

[0373] By way of example, the third body 710 is the telescopic member 100 or a part of the telescopic member 100 . More specifically, the third body 710 is the first connector 120 or a part of the first connector 120 .

[0374] By way of example, the third body 710 is the first connection portion 121 of the first connection head 120 , and the first connection portion 121 is located outside the first connection head 120 .

[0375] For example, the third body 710 is the grip 400 or a part of the grip 400 , more specifically, the third body 710 is the support leg 411 or a part of the support leg 411 , or the third body 710 is the first sleeve 420 or a part of the first sleeve 420 .

[0376] For example, refer to Fig.41 , the third body 710 is the functional body 300 or a part of the functional body 300.

[0377] For example, the cutting member 720 is directly fastened to the third body 710 via a fastener, and the fastener is a threaded member.

[0378] For example, the cutting member 720 is clamped to the third body 710 .

[0379] For example, the cutting member 720 is magnetically connected to the third body 710 .

[0380] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device also includes a retaining member 730, which is detachably mounted on the third body 710; the third body 710 is provided with a first installation cavity 701, and the cutting member 720 is inserted into the first installation cavity 701, and the retaining member 730 retains the cutting member 720 to prevent the cutting member 720 from escaping from the first installation cavity 701; a first gap 702 is provided between the retaining member 730 and the third body 710, the first installation cavity 701 is connected to the first gap 702, the cutting member 720 has a cutting edge 721, and the cutting edge 721 is located in the first gap 702, and the vehicle safety belt can enter the first gap 702.

[0381] It can be understood that the retaining member 730 is used to retain the cutting member 720 on one hand, and to form a first gap 702 with the third body 710 on the other hand, so that the emergency device with the retaining member 730 has a compact structure.

[0382] It can be understood that the cutting blade 721 is located in the first gap 702, which reduces the possibility of the cutting blade 721 accidentally injuring people.

[0383] For example, the emergency device further includes a second fastener 740 , which fastens the retaining member 730 to the third body 710 . The second fastener 740 may be a threaded member or a riveted member.

[0384] For example, the first installation cavity 701 is adapted to the cutting member 720 , the cutting member 720 is a sheet-like structure, and the first installation cavity 701 is a sheet-like cavity.

[0385] For example, the second fastener 740 has a second fastening axis, and the second fastener 740 applies a fastening force along the second fastening axis to the retaining member 730, and the retaining member 730 is circumferentially fixed around the second fastening axis relative to the third body 710. For example, the retaining member 730 has a first clamping portion 731, and the third body 710 has a second clamping portion 703. The first clamping portion 731 is clamped on the second clamping portion 703 so that the retaining member 730 is circumferentially fixed around the second fastening axis relative to the third body 710. The first clamping portion 731 is a protrusion and the second clamping portion 703 is a groove, or the first clamping portion 731 is a groove and the second clamping portion 703 is a protrusion.

[0386] For example, when the second fastening member 740 is a threaded member, the second fastening member 740 may be fastened to the third body 710 by rotating the second fastening member 740 around the second fastening axis.

[0387] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The telescopic member 100 includes a third body 710. The emergency device has a accommodating cavity 401 surrounded by a first wall 421. The telescopic member 100 is sleeved in the accommodating cavity 401. The telescopic member 100 can be retracted to accommodate the cutting member 720 in the accommodating cavity 401. The emergency device also includes a functional body 300. The telescopic member 100 includes a telescopic rod 110 and a first connecting head 120. The first connecting head 120 is installed at one end of the telescopic rod 110. The functional body 300 is installed on the first connecting head 120. The first connecting head 120 includes a third body 710. The telescopic member 100 can adjust the distance between the functional body 300 and the first gripping portion 901 by retracting.

[0388] It can be understood that the cutting member 720 and the functional body 300 are both installed on the first connector 120, so that the structure of the emergency device is more compact.

[0389] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37, the cutting member 720 translates so that when the cutting blade 721 cuts the vehicle safety belt, the cutting blade 721 is always located between the first limiting plane and the second limiting plane, and the first limiting plane is parallel to the second limiting plane; the first limiting plane intersects with the third body 710, the first limiting plane intersects with the retaining member 730, the second limiting plane intersects with the third body 710, and the second limiting plane intersects with the retaining member 730; the emergency device has a second opening 704, the second opening 704 is connected to the first gap 702, and the vehicle safety belt can enter the first gap 702 through the second opening 704, the second opening 704 includes a first side opening 704a, a first end opening 704c and a second side opening 704b that are sequentially connected, the first side opening 704a is opposite to the second side opening 704b, the first limiting plane is located between the first side opening 704a and the second side opening 704b, the second limiting plane is located between the first side opening 704a and the second side opening 704b, the first limiting plane is The first end opening 704c intersects, and the second limiting plane intersects with the first end opening 704c; the third main body 710 has a first wall 705a, and the blocking member 730 has a second wall 705b. There is a first gap 702 between the first wall 705a and the second wall 705b. The first end of the cutting blade 721 is close to or connected to the first wall 705a, and the second end of the cutting blade 721 is close to or connected to the second wall 705b; the telescopic member 100 extends in a direction parallel to the first straight line, and the cutting blade 721 extends in a direction parallel to the second straight line. The angle between the first straight line and the second straight line is less than or equal to 45°; the emergency device has a second gripping portion 902 for the user to hold, and the second gripping portion 902 surrounds the telescopic member 100. When the user holds the second gripping portion 902 and cuts the vehicle safety belt along the extension direction parallel to the telescopic member 100, the distance from the second gripping portion 902 to the cutting member 720 remains unchanged; the width of the first end opening 704c is less than or equal to 6mm.

[0390] It should be understood that the cutting direction of the cutting edge 721 is parallel to the first defining plane or the second defining plane, or the cutting edge 721 has a small angle with the first defining plane or the second defining plane.

[0391] It can be understood that when the cutting member 720 translates to cut the vehicle seat belt, the cutting blade 721 is always located between the first defining plane and the second defining plane, the first defining plane intersects with the third body 710, the first defining plane intersects with the blocking member 730, the second defining plane intersects with the third body 710, and the second defining plane intersects with the blocking member 730, so that the emergency device is not easy to cut people when cutting the seat belt or the like.

[0392] It can be understood that the first limiting plane is located between the first side opening 704a and the second side opening 704b, and the second limiting plane is located between the first side opening 704a and the second side opening 704b; because the cutting blade 721 is located between the first limiting plane and the second limiting plane during cutting, it is not easy for a person's hands or other parts to contact the cutting blade 721 through the first side opening 704a and the second side opening 704b, thereby making it difficult for the emergency device to injure people when cutting a seat belt or the like.

[0393] It can be understood that the safety belt or the like enters the first gap 702 through the first end opening 704c, and the first side opening 704a and the second side opening 704b serve as escape spaces for the safety belt.

[0394] It can be understood that the first defined plane intersects with the first end opening 704c, and the second defined plane intersects with the first end opening 704c, so as to facilitate the safety belt to enter the first gap 702 through the first end opening 704c, so as to facilitate the cutting blade 721 to cut the safety belt.

[0395] It can be understood that the first end of the cutting blade 721 is close to or connected to the first wall 705a, and the second end of the cutting blade 721 is close to or connected to the second wall 705b, which facilitates the cutting blade 721 to cut the safety belt when it moves from the first end opening 704c to the bottom wall of the first gap 702.

[0396] It can be understood that the angle between the first straight line and the second straight line is less than or equal to 45°, and when the second gripping portion 902 is located at the telescopic member 100, it is convenient for the cutting blade 721 to cut the safety belt.

[0397] For example, the angle between the first straight line and the second straight line is greater than or equal to 15°.

[0398] For example, the angle between the first straight line and the second straight line may be 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc.

[0399] It can be understood that the width of the first end opening 704c is less than or equal to 6 mm, so that it is difficult for a person's finger to enter the first gap 702 from the first end opening 704c, thereby avoiding accidental injury by the cutting edge 721.

[0400] For example, the width of the first end opening 704c is 6 mm, 5 mm, 4 mm, 3 mm, etc.

[0401] For example, the first gap 702 has a bottom wall, which is connected to the first wall surface 705a and the second wall surface 705b. The bottom wall of the first gap 702 is opposite to the first end opening 704c, and the width of the first gap 702 gradually narrows from the first end opening 704c to the bottom wall of the first gap 702.

[0402] For example, the second grip portion 902 surrounds the telescopic member 100 , which may mean that the second grip portion 902 is located in the telescopic member 100 and surrounds the telescopic member 100 , or the second grip portion 902 is located in a middle member and surrounds the middle member, and the middle member surrounds the telescopic member 100 .

[0403] For example, when the user holds the second grip 902 to cut the vehicle seat belt along the extension direction parallel to the telescopic member 100, the distance from the second grip 902 to the cutting member 720 remains unchanged. This may refer to that the second grip 902 is fixed relative to the cutting member 720, and the distance from the second grip 902 to the cutting member 720 remains constant. It may also refer to that the distance from the second grip 902 to the cutting member 720 can be changed. When the cutting member 720 is used for cutting, the distance between the cutting member 720 and the second grip 902 is maximized or minimized, so that the distance from the second grip 902 to the cutting member 720 remains unchanged when the cutting member 720 is cutting.

[0404] For example, the cutting member 720 is fixed relative to the first telescopic section 111 a , and the second gripping portion 902 is located at the first telescopic section 111 a . When the second gripping portion 902 is gripped for cutting, the distance between the second gripping portion 902 and the cutting member 720 remains unchanged.

[0405] For example, the cutting piece 720 is fixed relative to the first telescopic section 111a, the second gripping portion 902 is located at the second telescopic section 111b, the second telescopic section 111b and the first telescopic section 111a are adjacent or non-adjacent telescopic sections, and when the cutting piece 720 is used for cutting, the second telescopic section 111b is extended to the maximum length relative to the first telescopic section 111a, so that when the second telescopic section 111b is gripped to cut the safety belt, the distance between the second gripping portion 902 and the cutting piece 720 remains unchanged.

[0406] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The cutting piece 720 is in the shape of a sheet, and the thickness of the first mounting cavity 701 is adapted to the cutting piece 720; the third main body 710 has a relatively parallel first side wall 706a and a second side wall 706b, the first side wall 706a is parallel to the insertion direction of the cutting piece 720, the cutting piece 720 has a relatively parallel first side edge 707a and a second side edge 707b, the first side edge 707a is parallel to the insertion direction of the cutting piece 720, the first side edge 707a is adjacent to the first side wall 706a, and the second side edge 707b is adjacent to the second side wall 706b; the first mounting cavity 701 also has a first abutting wall, the first abutting wall abuts against the cutting piece 720 to prevent the cutting blade 721 from retracting into the first mounting cavity 701; the blocking piece 730 has a first blocking wall 705c, the first blocking wall 705c abuts against the cutting piece 720 to prevent the cutting piece 720 from slipping out of the first mounting cavity 701.

[0407] It can be understood that the thickness of the first installation cavity 701 is adapted to the cutting member 720 , thereby preventing the cutting member 720 from swinging in the thickness direction.

[0408] It can be understood that the first side wall 706a, the second side wall 706b, the first side edge 707a, and the second side edge 707b are all parallel to the insertion direction of the cutting piece 720, so that the cutting piece 720 is inserted into the first installation cavity 701, and the first side edge 707a is adjacent to the first side wall 706a, and the second side edge 707b is adjacent to the second side wall 706b, so that the cutting piece 720 is circumferentially fixed relative to the first installation cavity 701, thereby preventing the cutting piece 720 from rotating relative to the first installation cavity 701 when the cutting blade 721 cuts the safety belt.

[0409] For example, the first retaining wall 705c is located on the second wall surface 705b.

[0410] For example, the retaining member 730 defines a second groove 705d communicating with the second wall surface 705b, and the first retaining wall 705c is located in the second groove 705d.

[0411] For example, the first abutting wall and the first retaining wall 705 c are respectively located on two opposite sides of the cutting member 720 .

[0412] Illustratively, the first side wall 706 a is located in or partially located in the first mounting cavity 701 .

[0413] Illustratively, the second side wall 706 b is located in or partially located in the first mounting cavity 701 .

[0414] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device also includes a functional body 300, which is rotatably installed on the telescopic member 100. The functional body 300 can be rotated to a first position relative to the telescopic member 100. When the functional body 300 is located at the first position relative to the telescopic member 100, the hammer member 200 and the functional body 300 are respectively located on opposite sides of the telescopic member 100; the telescopic member 100 can be telescoped to adjust the distance between the functional body 300 and the first gripping portion 901.

[0415] For example, the functional body 300 can be maintained in the telescopic member 100 in the process of changing the direction of the functional body 300 relative to the rotation process of the telescopic member 100. For example, the functional body 300 can be maintained in the telescopic member 100 in the process of changing the direction of the functional body 300 by the hand strength of the user. For another example, the functional body 300 and the telescopic member 100 are directly or indirectly interference fit. For another example, in the process of the functional body 300 rotating relative to the telescopic member 100 to change the direction of use of the functional body 300, the functional body 300 can be locked in the telescopic member 100, for example, the functional body 300 is fastened to the telescopic member 100 by the first fastener 610, or the functional body 300 is held in the telescopic member 100 by a holding structure. In the process of the functional body 300 rotating relative to the telescopic member 100 to change the direction of use of the functional body 300, when the functional body 300 needs to be locked, the functional body 300 can be locked in the telescopic member by the fastener 610 or the holding structure. For another example, the functional body 300 is provided with damped rotation at the telescopic member 100. In the process that the functional body 300 rotates relative to the telescopic member 100 to change the use direction of the functional body 300, the functional body 300 can be damped and maintained at the telescopic member 100. For example, a damping ring is provided between the functional body 300 and the telescopic member 100, and the damping ring can be made of a flexible material. For another example, the telescopic member 100 directly or indirectly contacts the functional body 300 by friction, so that friction damping is generated between the telescopic member 100 and the functional body 300. The first fastener 610 can be used to generate friction between the telescopic member 100 and the functional body 300 (for example, the first fastener 610 applies a fastening force to the telescopic member and the functional body along the direction of the first axis 101. The first fastener 610 can be a threaded member, a riveted member, etc.

[0416] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further comprises a functional body 300 , which is rotatably mounted on the telescopic member 100 , and the functional body 300 can be retained on the telescopic member 100 ; the telescopic member 100 can be telescoped to adjust the distance between the functional body 300 and the first gripping portion 901 .

[0417] It can be understood that the functional body 300 is retained on the telescopic member 100 so that the functional body 300 is maintained at a position relative to the telescopic member 100 , for example, the functional body 300 is maintained at a first position or a second position relative to the telescopic member 100 .

[0418] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37The telescopic member 100 includes a telescopic rod 110, and the telescopic rod 110 includes at least three telescopic joints 111 which are sequentially sleeved; the at least three telescopic joints 111 include a front telescopic joint and a rear telescopic joint. When the telescopic rod 110 is in an extended state, the front telescopic joint and the rear telescopic joint are respectively located at two ends of the telescopic rod 110, and when the telescopic rod 110 is in a contracted state, the front telescopic joint can be contracted to the rear telescopic joint, and the hammer member 200 is installed on the front telescopic joint. The emergency device also includes a gripping member 400, and the gripping member 400 has a first gripping portion 901. The gripping member 400 is installed on the telescopic member 100, and the accommodating cavity 401 is provided on the gripping member 400. The gripping member 400 surrounds the rear telescopic joint, and the gripping member 400 is stationary relative to the rear telescopic joint when the telescopic member 100 is extended or retracted.

[0419] It can be understood that the hammering member 200 and the holding member 400 are respectively arranged at the front telescopic joint and the rear telescopic joint, so that the hammering member 200 has a larger range of adjustable distance relative to the holding member 400.

[0420] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 , the maximum length of the telescopic rod 110 is at least 3 times the shortest length of the telescopic rod 110. The advantage of such an arrangement is that the telescopic range of the telescopic rod 110 is larger.

[0421] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The emergency device further includes a protective cover 630, which can be placed on the hammer 200 and is flexibly connected to the telescopic member 100. The advantage of such a configuration is that when the hammer 200 is not in use, the hammer 200 is prevented from accidentally injuring a person; the protective cover 630 is flexibly connected to the telescopic member 100, which facilitates the removal of the protective cover 630 from the hammer 200 and prevents the protective cover 630 from being separated from the telescopic member 100 and thus lost.

[0422] For example, the protective cover 630 is flexibly connected to the first connecting head 120 of the telescopic member 100 .

[0423] For example, the emergency device also includes a flexible connector 640, which is used to achieve a flexible connection between the protective cover 630 and the first connector 120. One end of the flexible connector 640 is connected to the protective cover 630, and the other end is connected to the telescopic member 100. The flexible connector 640 and the protective cover 630 are both made of polymer materials such as plastic. The flexible connector 640 is integrally connected to the protective cover 630, and the flexible connector 640 is detachably connected to the telescopic member 100.

[0424] For example, the flexible connector 640 includes a flexible portion and a hoop 641 connected to the flexible portion. One end of the flexible portion is connected to the hoop 641 and the other end is connected to the protective cover 630 . The hoop 641 is clamped on the telescopic member 100 .

[0425] For example, the first connector 120 is provided with a second mounting protrusion 124 , the second mounting protrusion 124 is surrounded by a hoop groove 106 , and the hoop ring 641 is hooped in the hoop groove 106 .

[0426] For example, the first fastener 610 passes through the second mounting protrusion 124 , and the head of the first fastener 610 is received in the second mounting protrusion 124 .

[0427] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The functional body 300 is an emergency light, or the functional body is a fixture that carries an electronic terminal.

[0428] Reference Figure 43 to Figure 45 In some implementations of the embodiments of the present application, the emergency device also includes at least three legs 411 and a fourth body 430, the fourth body is installed on the telescopic member 100, each leg 411 is rotatably installed on the fourth body 430, at least three legs 411 can be opened or retracted relative to the fourth body 430, two adjacent legs 411 are arranged at intervals, and at least three legs 411 can be supported on a supporting surface when opened to support the telescopic member 100, and the telescopic member 100 can adjust the distance between the supporting surface and the functional body 300 by telescoping, the gripping member 400 includes at least the fourth body 430, the fourth body 430 is provided with a accommodating chamber 401, the telescopic member 100 is installed with a hammering member 200 and a cutting member 720, the telescopic member 100 can be contracted to cause the hammering member 200 and the cutting member 720 to be contracted in the accommodating chamber 401, and the telescopic member 100 can be contracted to cause one end of the telescopic member 100 to be accommodated in the accommodating chamber 401. When the functional body 300 is in the second position and the telescopic member 100 is in the contracted state, the functional body 300 abuts against the fourth body 430 .

[0429] Specifically, the fourth body 430 has a first wall 421, the first wall 421 surrounds and forms a receiving cavity 401, the emergency device has a first opening 402, and the telescopic member 100 is retracted so that the hammer member 200, the cutting member 720, and one end of the telescopic member 100 can be accommodated in the receiving cavity 401 through the first opening 402. When the functional body 300 is in the second position and the telescopic member 100 is in the retracted state, the functional body 300 abuts against the end wall of the first opening 402.

[0430] Specifically, when the functional body 300 is in the second position, at least three legs 411 are stored in the fourth body 430, and the telescopic member 100 is in a retracted state, the emergency device as a whole presents a strip-shaped structure.

[0431] For example, the fourth body 430 is installed on the rear telescopic joint of the telescopic member 100 , and when the telescopic member 100 is telescoped, the fourth body 430 is fixed relative to the rear telescopic joint.

[0432] For example, when the support leg 411 is in the open state, the supporting end of the support leg 411 can be rotated upward and folded into the fourth body 430 .

[0433] For example, the legs 411 are folded onto the surface of the fourth body 430 .

[0434] For example, the fourth body 430 is provided with a receiving groove 405, and the support leg 411 can be folded into the receiving groove 405 of the fourth body 430. After the support leg 411 is received in the receiving groove 405 of the fourth body 430, the support leg 411 protrudes from the outer surface of the fourth body 430, and the first gripping portion 901 is located on the fourth body 430 and the support leg 411; or, after the support leg 411 is received in the receiving groove 405 of the fourth body 430, the support leg 411 is recessed in the outer surface of the fourth body 430, and the first gripping portion 901 is located on the fourth body 430.

[0435] For example, the gripping member 400 includes a fourth body 430 and at least three legs 411 in a folded state, and the first gripping portion 901 is located on the fourth body 430 and the at least three legs 411 in a folded state.

[0436] For example, the support leg 411 is rotatably mounted on the fourth main body 430, and the support leg 411 can be maintained in a supporting state. For example, the fourth main body 430 is installed with a supporting member 440, and the main part of the supporting member 440 is built into the fourth main body 430. The supporting member 440 is rotatably mounted on the fourth main body 430. The supporting member 440 has at least three supporting portions 441, and the at least three supporting portions 441 respectively correspond to at least three support legs 411. The supporting member 440 is provided with at least three avoidance gaps 406, and the at least three avoidance gaps 406 respectively correspond to at least three support legs 411, and each avoidance gap 406 is located between two adjacent supporting portions 441. The supporting member 440 can be toggled by the user so that the supporting member 440 is in the fifth position or the sixth position relative to the fourth main body 430. Specifically, the supporting member 440 has a toggle portion 442, which protrudes from the outer surface of the fourth main body 430. Toggling the toggle portion 442 can make the supporting member 440 in different positions. The toggle portion 442 is connected to one of the supporting portions 441. When the supporting member 440 is in the fifth position, the support leg 411 can be rotated relative to the fourth main body 430, and the end of the support leg 411 away from the supporting end can pass through the avoidance gap 406. When the supporting member 440 is in the fifth position, at least three support legs 411 can be opened relative to the fourth main body 430, and the supporting member 440 is rotated to the sixth position, so that the support leg 411 is abutted against the corresponding supporting portion 441. Specifically, the top surface of the supporting portion 441 has a supporting surface 441a, and the supporting surface 441a is abutted against the end of the support leg away from the supporting end.

[0437] When the resisting member 440 is at the fifth position and the supporting leg 411 is received in the fourth body 430 , a portion of the supporting leg 411 is locked in the avoidance gap 406 , so that the resisting member 440 cannot be moved to the sixth position.

[0438] In some other implementations of the embodiments of the present application, the emergency device further includes at least three legs 411, each leg 411 is rotatably mounted on the telescopic member 100, the at least three legs 411 can be opened or retracted, and the at least three legs 411 can be supported on a support surface to support the telescopic member 100 when opened, and the telescopic member 100 can adjust the distance between the support surface and the functional body 300 by telescoping, and the first gripping portion 901 is located at the at least three legs 411 in the retracted state, or the first gripping portion 901 is located at the telescopic member 100. For example, when the at least three legs 411 are retracted, each leg 411 is retracted to the telescopic member 100, and there is no spacing between two adjacent legs 411, the first gripping portion 901 is located at the at least three legs 411 in the retracted state, or there is a spacing between two adjacent legs, and the first gripping portion 901 is located at the telescopic member 100 and at least three legs 411 in the retracted state. For another example, the telescopic member 100 may be provided with a receiving groove, and the support leg 411 may be received in the receiving groove, and at least three support legs 411 are received in the receiving groove of the telescopic member. When at least three support legs are received in the receiving groove of the telescopic member, the first gripping portion 901 is located on the telescopic member 100, or the first gripping portion 901 is located on the telescopic member 100 and at least three support legs 411.

[0439] For example, when the support leg 411 is in an open state relative to the telescopic member 100 , the supporting end of the support leg 411 can be rotated upward and retracted into the telescopic member 100 .

[0440] For example, when the support leg 411 is in an open state relative to the telescopic member 100 , the supporting end of the support leg 411 can be rotated downward to be retracted into the telescopic member 100 .

[0441] In some other implementations of the embodiments of the present application, the emergency device further includes at least three legs 411, each leg 411 is rotatably mounted on the telescopic member 100, the at least three legs 411 can be opened or retracted, and the at least three legs 411 can be supported on a support surface to support the telescopic member 100 when opened, and the telescopic member 100 can adjust the distance between the support surface and the functional body 300 by telescoping, and the legs 411 can rotate relative to the telescopic member 100 so that the at least three legs 411 can be retracted, and the at least three legs 411 in the retracted state are the first gripping portion 901. When the at least three legs 411 are retracted, two adjacent legs 411 are retracted to each other.

[0442] For example, when the supporting legs 411 are in an open state relative to the telescopic member 100 , the supporting ends of the supporting legs 411 rotate downward to allow at least three supporting legs to be retracted.

[0443] The present application also provides an emergency device, referring to Figure 1-Figure 37 , including a telescopic member 100 and a cutting member 720, the cutting member 720 is installed on the telescopic member 100, and the cutting member 720 is used to cut the vehicle seat belt; the emergency device has a accommodating cavity 401 surrounded by a first wall 421, the telescopic member 100 is sleeved in the accommodating cavity 401, and the cutting member 720 can be accommodated in the accommodating cavity 401 by contracting the telescopic member 100.

[0444] It can be understood that the emergency device has a accommodating cavity 401 surrounded by a first wall 421, and the telescopic member 100 is sleeved in the accommodating cavity 401. The emergency device also includes a cutting member 720 for cutting the vehicle seat belt. The cutting member 720 is installed on the telescopic member 100. The telescopic member 100 can be retracted to allow the cutting member 720 to be accommodated in the accommodating cavity 401. The advantage of this arrangement is that when the emergency device is not in use, the cutting member 720 is prevented from accidentally injuring people.

[0445] In some implementations of the embodiments of the present application, reference is made to Figure 1-Figure 37 The cutting member 720 is detachably mounted on the telescopic member 100.
