Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a rotary drive component and a vehicle. Background Art

[0002] Vehicles are usually equipped with cameras to capture images to achieve various functions such as in-vehicle monitoring, driving recording, and face recognition. In the existing technology, most cameras are fixed, with a fixed shooting angle, and can only capture fixed positions, which is inconvenient to use. Utility Model Content

[0003] The purpose of the utility model is to provide a rotary drive assembly and a vehicle, aiming to solve the problem of inconvenience in using a camera.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] In a first aspect of the present application, a rotary drive assembly is provided, comprising a rotary drive member, a transmission assembly, and a driven member. The transmission assembly is connected to a rotary output end of the rotary drive member. The driven member is connected to the transmission assembly. The rotary drive member is configured to drive the transmission assembly to rotate the driven member. The rotary axis of the rotary output end is offset from the rotary axis of the driven member.

[0006] Through the above arrangement, when it is necessary to rotate the driven part or adjust the position of the driven part, the rotating driving part can be started to rotate the rotating output end and output power, thereby driving the transmission component to move. The transmission component transmits the power to the driven part to drive the driven part to rotate and adjust the position of the driven part.

[0007] In this way, the user can rotate the driven member as needed, thereby adjusting the position of the driven member to a desired position, thereby facilitating the use of the driven member.

[0008] In addition, since the rotating shaft of the rotating output end and the rotating shaft of the driven part are staggered, when installing the rotary drive assembly, the positions of the rotary drive part and the transmission assembly can be adjusted as needed so that the spatial setting of the rotary drive assembly meets the requirements of installing the rotary drive assembly on the vehicle, thereby further facilitating the use of the rotary drive assembly.

[0009] In some embodiments, the transmission assembly includes a first worm, a first worm wheel, and a transmission mechanism. The first worm is connected to the rotational output end, and the rotational axis of the first worm is coaxially arranged with the rotational axis of the rotational output end. The first worm wheel meshes with the first worm. The input end of the transmission mechanism is connected to the first worm wheel, and the output end of the transmission mechanism is connected to the driven member.

[0010] With this arrangement, during the rotation of the driven member, the power output by the rotary drive member is transmitted via the first worm gear to the first worm wheel, and then via the transmission mechanism to the driven member, thereby driving the driven member to rotate. This reduces the rotational speed of the driven member and increases the output torque of the transmission mechanism to drive the driven member, compared to a case where the output shaft of the rotary drive member is directly connected to the transmission mechanism. This allows the driven member to rotate more smoothly, thereby ensuring the stability of the overall structure of the rotary drive assembly.

[0011] In some embodiments, the transmission mechanism includes a first rod and a second rod. One end of the first rod is connected to the first worm gear. One end of the second rod is rotationally connected to an opposite end of the first rod. The opposite end of the second rod is rotationally connected to a driven member, and the second rod is offset relative to the rotation axis of the driven member.

[0012] Through the above-mentioned arrangement, since the rotating axis of the rotating output end is staggered with the rotating axis of the driven part, and the second rod body is staggered with the rotating axis of the driven part relative to the rotating axis of the driven part, the rotating axes of the first worm gear and the driven part, the driven part, the first rod body and the second rod body can form a structure similar to a hinge four-bar linkage. Specifically, the rotating axis of the first worm gear and the driven part is similar to the fixed rod in the hinge four-bar linkage, and the driven part, the first rod body and the second rod body are respectively similar to the three rotating rods in the hinge four-bar linkage. In this way, when the driven part needs to be rotated, the rotating driving part can be started, so that the rotating driving part drives the first worm gear to rotate through the first worm gear, and the first worm gear can drive the first rod body to rotate, and then drive the second rod body and the driven part to rotate, thereby driving the driven part to rotate and adjusting the position of the driven part.

[0013] In some embodiments, the transmission mechanism includes a rack connected to the driven member and meshing with the first worm gear.

[0014] Through the above arrangement, since the first worm gear is engaged with the rack, after the rotary driving member is started, the first worm gear will rotate to drive the rack and the driven member to rotate around the rotation axis of the driven member, thereby driving the driven member to rotate and realize the adjustment of the position of the driven member.

[0015] In some embodiments, the transmission mechanism includes a screw, a sliding block, a sliding plate, a limiter and a third rod. The screw is connected to the first worm gear, and the rotation axis of the screw is coaxially arranged with the rotation axis of the first worm gear. The sliding block is provided with a mounting channel, the mounting channel is provided with a thread, the screw is passed through the mounting channel, and is screwed to the thread. The sliding plate is connected to one side of the sliding block in the circumferential direction of the mounting channel. The limiter is relatively fixed to the driven part, and the limiter is used to limit the circumferential movement of the sliding plate along the mounting channel. One end of the third rod is rotationally connected to the sliding block, and the other end of the third rod is rotationally connected to the driven part. The third rod is staggered relative to the rotation axis of the driven part.

[0016] Through the above setting, after starting the rotary drive member, the first worm gear will rotate to drive the screw to rotate. Since the limit member can limit the circumferential movement of the sliding plate along the installation channel, the sliding plate is connected to the sliding block, and the screw is threadedly connected to the thread, the sliding block will move axially along the installation channel under the action of the screw and the limit member.

[0017] In this case, the third rod body, the sliding block and the driven part can form a structure similar to a crank slider mechanism. Specifically, the sliding block is similar to the slider in the crank slider mechanism, the third rod body is similar to the connecting rod in the crank slider mechanism, and the driven part is similar to the crank in the crank slider mechanism.

[0018] In this way, when the driven part needs to be rotated, the rotating driving part can be started, so that the rotating driving part drives the first worm wheel to rotate through the first worm, and the first worm wheel can drive the sliding block to slide through the screw, thereby driving the third rod body and the driven part to rotate, thereby driving the driven part to rotate and realizing the adjustment of the position of the driven part.

[0019] In some embodiments, the transmission assembly further includes a second worm and a second worm wheel. The second worm's rotation axis is coaxial with the rotation axis of the first worm wheel, and the second worm is connected to the first worm wheel. The second worm wheel meshes with the second worm. The input end of the transmission mechanism is connected to the second worm wheel.

[0020] With this arrangement, during the rotation of the driven member, the power output from the first worm gear is transmitted via the second worm to the second worm wheel, and then via the transmission mechanism to the driven member, thereby driving the driven member to rotate. Thus, the arrangement of the second worm and the second worm wheel further reduces the rotational speed of the driven member and further increases the output torque of the transmission mechanism driving the driven member to rotate. This enables the driven member to rotate more smoothly, thereby further ensuring the stability of the overall structure of the rotary drive assembly.

[0021] In some embodiments, the transmission assembly further comprises a protective member, the protective member abuts against the first worm gear, and the input end of the transmission mechanism is connected to the protective member. When the first worm gear rotates, the friction force between the protective member and the first worm gear is static friction.

[0022] In some embodiments, the transmission assembly further comprises a housing, the housing having a receiving cavity and a first opening communicating with the receiving cavity, the driven member being disposed in the first opening and rotatably connected to the housing, and the driven member being rotatable relative to the housing to extend out of or into the receiving cavity.

[0023] With the above arrangement, when the driven member is needed, the rotating driving member can be activated to rotate the driven member and extend it out of the accommodating cavity, thereby satisfying the user's need to use the driven member. When the driven member is not needed, the rotating driving member can be activated to rotate the driven member and extend it into the accommodating cavity, thereby protecting the driven member.

[0024] In some embodiments, the transmission assembly further comprises a bracket disposed within the accommodating cavity and connected to the housing. The bracket is provided with a first mounting slot and a second mounting slot, wherein a second opening is directly provided between the first mounting slot and the second mounting slot, and the first mounting slot and the second mounting slot are connected via the second opening. A first worm is disposed within the first mounting slot and partially extends through the second opening. A first worm wheel is disposed within the second mounting slot and engages with the portion of the first worm wheel extending through the second opening.

[0025] With the above arrangement, since the bracket is connected to the housing, the first worm is inserted into the first mounting slot, and the first worm wheel is disposed in the second mounting slot, the bracket can secure the first worm wheel and the first worm within the housing cavity, thereby achieving installation of the first worm wheel and the first worm. Furthermore, the provision of the second opening ensures normal meshing of the first worm and the first worm wheel, thereby ensuring normal function of the transmission assembly.

[0026] In a second aspect of the present application, a vehicle is provided, comprising a vehicle body and the above-mentioned rotary drive assembly, wherein the rotary drive assembly is arranged on the vehicle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0052] Vehicles are usually equipped with cameras to capture images to achieve various functions such as in-vehicle monitoring, driving recording, and face recognition. In the existing technology, most cameras are fixed, with a fixed shooting angle, and can only capture fixed positions, which is inconvenient to use.

[0053] Based on this, the present application provides a vehicle, such as Figure 1 As shown, Figure 1 FIG1 is a schematic diagram of the external structure of a vehicle 100 , which includes a vehicle body 10 and a rotary drive assembly 20 . The rotary drive assembly 20 is connected to the vehicle body 10 .

[0054] Illustratively, the vehicle 100 includes one rotary drive assembly 20 , and may also include a plurality of rotary drive assemblies 20 .

[0055] Specifically, if Figure 2 、 Figure 3 As shown, Figure 2 for Figure 1An exploded schematic diagram of the rotary drive assembly 20, Figure 3 for Figure 2 Schematic diagram of the explosion of the transmission assembly 2, the rotary drive assembly 20 includes a rotary drive member 1, a transmission assembly 2 and a driven member 3. The transmission assembly 2 is connected to the rotary output end of the rotary drive member 1. The driven member 3 is connected to the transmission assembly 2.

[0056] The rotary drive member 1 is used to drive the transmission assembly 2 to move, thereby driving the driven member 3 to rotate. The rotary shaft of the rotary output end and the rotary shaft of the driven member 3 are staggered.

[0057] It should be noted that the staggered setting of the rotation axis of the rotation output end and the rotation axis of the driven part 3 means that the rotation axis of the rotation output end and the rotation axis of the driven part 3 do not intersect or colinear, that is, the rotation axis of the rotation output end and the rotation axis of the driven part 3 are located on different planes.

[0058] It can be understood that the rotation axis of the rotation output end and the rotation axis of the driven member 3 may be parallel or non-parallel.

[0059] It can be understood that the rotation axis of the rotation output end and the rotation axis of the driven member 3 are relatively fixed.

[0060] Illustratively, the rotary drive member 1 may include an electric motor, a hydraulic motor, and the like.

[0061] Through the above arrangement, when it is necessary to rotate the driven part 3 or adjust the position of the driven part 3, the rotary driving part 1 can be started to rotate the rotary output end and output power, thereby driving the transmission component 2 to move. The transmission component 2 transmits the power to the driven part 3 to drive the driven part 3 to rotate and adjust the position of the driven part 3.

[0062] In this way, the user can rotate the driven member 3 as needed, thereby adjusting the position of the driven member 3 to a desired position, thereby facilitating the use of the driven member 3 .

[0063] In addition, since the rotating shaft of the rotating output end is staggered with the rotating shaft of the driven part 3, when installing the rotating drive component 20, the positions of the rotating drive component 1 and the transmission component 2 can be adjusted as needed so that the spatial setting of the rotating drive component 20 meets the requirements of installing the rotating drive component 20 on the vehicle 100, thereby further facilitating the use of the rotating drive component 20.

[0064] Exemplarily, the driven component 3 may be a camera 31 , which may be installed at the rear of the vehicle to capture a reversing image, or may be installed inside the vehicle to capture a driving record of the vehicle 100 or monitor the interior of the vehicle 100 .

[0065] By setting the rotating driving member 1 and the transmission assembly 2, the shooting angle of the camera 31 can be adjusted, so that the camera 31 can shoot the position that needs to be shot, meeting the user's usage requirements for the camera 31.

[0066] For example, the driven member 3 may be a control panel mounted on the center console of the vehicle 100. By rotating the driving member 1 and the transmission assembly 2, the position of the control panel can be adjusted, thereby facilitating user operations on the control panel and making it easier for the user to use the vehicle 100.

[0067] In order to ensure the stability of the driven part 3 during rotation, in some embodiments, the transmission assembly 2 includes a gear reducer, the output shaft of the rotating driving part 1 is connected to the input shaft of the gear reducer, and the output shaft of the gear reducer is connected to the driven part 3.

[0068] In some embodiments, as Figure 2 、 Figure 4 As shown, Figure 4 for Figure 2 FIG2 is a schematic diagram of an assembled state of the rotary drive assembly 20 in FIG2 . The rotary drive assembly 20 further includes a housing 4 having a receiving cavity 41. The driven member 3 is disposed in the receiving cavity 41 and is rotatably connected to the housing 4. The driven member 3 can rotate relative to the housing 4 to extend into or out of the receiving cavity 41.

[0069] It should be noted that the driven member 3 and the housing 4 can be rotatably connected together by a hinge, or a fixed shaft can pass through the driven member 3 and the housing 4 to achieve the rotatable connection between the driven member 3 and the housing 4. The subsequent rotatable connection includes various connection methods such as hinges and fixed-axis rotatable connections.

[0070] With the above arrangement, the rotary driving member 1 can be activated when the driven member 3 is needed, causing the driven member 3 to rotate and extend out of the accommodating cavity 41, thereby satisfying the user's need to use the driven member 3. Furthermore, when the driven member 3 is not needed, the rotary driving member 1 can be activated, causing the driven member 3 to rotate and extend into the accommodating cavity 41, thereby protecting the driven member 3.

[0071] In some embodiments, as Figure 2 、 Figure 3 As shown, the transmission assembly 2 includes a first worm 21 , a first worm wheel 22 and a transmission mechanism 23 .

[0072] The first worm 21 is connected to the rotation output end, and the rotation axis of the first worm 21 is coaxially arranged with the rotation axis of the rotation output end. The first worm wheel 22 is meshed with the first worm 21 .

[0073] An input end of the transmission mechanism 23 is connected to the first worm gear 22 , and an output end of the transmission mechanism 23 is connected to the driven member 3 .

[0074] Through the above arrangement, during the rotation of the driven member 3, the power output by the rotary driving member 1 will be transmitted to the first worm wheel 22 through the first worm 21, and then transmitted to the driven member 3 through the transmission mechanism 23, thereby driving the driven member 3 to rotate.

[0075] In this way, compared with the output shaft of the rotating driving member 1 being directly connected to the transmission mechanism 23, the rotational speed of the driven member 3 can be reduced, and the output torque of the transmission mechanism 23 driving the driven member 3 to rotate can be increased, so that the driven member 3 can rotate more smoothly, thereby ensuring the stability of the overall structure of the rotating driving assembly 20.

[0076] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 As shown, the rotary drive assembly 20 further includes a bracket 5, which is disposed in the accommodating cavity 41 and connected to the housing 4. The bracket 5 is provided with a first mounting slot 51 and a second mounting slot 52. A second opening 53 is directly provided between the first mounting slot 51 and the second mounting slot 52, and the first mounting slot 51 and the second mounting slot 52 are in communication through the second opening 53.

[0077] The first worm 21 is disposed in the first mounting slot 51 and partially passes through the second opening 53 . The first worm wheel 22 is disposed in the second mounting slot 52 and meshes with the portion of the first worm 21 passing through the second opening 53 .

[0078] Through the above arrangement, since the bracket 5 is connected to the outer shell 4, and the first worm 21 is inserted into the first mounting groove 51, and the first worm wheel 22 is arranged in the second mounting groove 52, the first worm wheel 22 and the first worm 21 can be fixed in the accommodating cavity 41 of the outer shell 4 through the bracket 5, thereby realizing the installation of the first worm wheel 22 and the first worm 21.

[0079] Furthermore, the provision of the second opening 53 can ensure normal engagement between the first worm 21 and the first worm wheel 22 , thereby ensuring normal function of the transmission assembly 2 .

[0080] In some examples, such as Figure 3 As shown, the bracket 5 further includes a first end plate 54 and a second end plate 55. The rotary drive member 1 is disposed in the first mounting slot 51. The first end plate 54 is connected to the opening of the first mounting slot 51 to confine the rotary drive member 1 and the first worm 21 within the first mounting slot 51, thereby enabling installation of the first worm 21 and the rotary drive member 1. The second end plate 55 is connected to the opening of the second mounting slot 52 to confine the first worm gear 22 within the second mounting slot 52, thereby enabling installation of the first worm gear 22.

[0081] On this basis, in some embodiments, such as Figure 3As shown, the transmission assembly 2 further includes a second worm 24 and a second worm wheel 25 .

[0082] The rotation axis of the second worm 24 is coaxial with the rotation axis of the first worm wheel 22, and the second worm 24 is connected to the first worm wheel 22. The second worm wheel 25 is meshed with the second worm 24. The input end of the transmission mechanism 23 is connected to the second worm wheel 25.

[0083] Through the above arrangement, during the rotation of the driven member 3, the power output from the first worm gear 22 will be transmitted to the second worm gear 25 through the second worm 24, and then transmitted to the driven member 3 through the transmission mechanism 23, thereby driving the driven member 3 to rotate.

[0084] In this way, by setting the second worm 24 and the second worm wheel 25, the rotational speed of the driven part 3 can be further reduced, and the output torque of the transmission mechanism 23 to drive the driven part 3 to rotate can be further improved, so that the driven part 3 can rotate more smoothly, thereby further ensuring the stability of the overall structure of the rotation drive assembly 20.

[0085] In some examples, such as Figure 3 As shown, the bracket 5 is provided with a third mounting groove 56, the second worm 24 is provided in the third mounting groove 56, a third opening is provided between the third mounting groove 56 and the second mounting groove 52, the second worm 24 partially passes through the third opening, and the second worm wheel 25 is engaged with the part of the second worm 24 passing through the third opening.

[0086] In some examples, the angle between the axial direction of the first worm 21 and the axis of the first worm wheel 22 is 90°, and the angle between the axial direction of the second worm 24 and the axial direction of the second worm wheel 25 is 90°.

[0087] In this way, by setting the first worm 21, the first worm wheel 22, the second worm 24 and the second worm wheel 25, the transmission direction of the power output of the rotary drive member 1 can be changed, so that the structure of the transmission component 2 can be made more compact, thereby further reducing the space required by the transmission component 2, so as to facilitate the spatial setting of the rotary drive component 20.

[0088] It can be understood that when the driven component 3 is disposed inside the vehicle 100 , the structure of the transmission assembly 2 is more compact and the utilization rate of the interior space of the vehicle 100 can be improved.

[0089] In some examples, the transmission assembly 2 may further include a third worm and a third worm wheel. The rotation axis of the third worm is coaxial with the rotation axis of the second worm wheel 25, and the third worm is connected to the second worm wheel 25. The third worm wheel meshes with the third worm. The input end of the transmission mechanism 23 is connected to the third worm wheel.

[0090] In some examples, such as Figure 1、 Figure 3 As shown, the rotary drive assembly 20 further includes a third end plate, which is connected to the opening of the third mounting slot 56 .

[0091] In some embodiments, as Figure 2 As shown, the transmission mechanism 23 includes a first rod 231 and a second rod 232 .

[0092] One end of the first rod 231 is connected to the first worm gear 22. One end of the second rod 232 is rotationally connected to the opposite end of the first rod 231. The opposite end of the second rod 232 is rotationally connected to the driven member 3, and the second rod 232 is offset from the rotation axis of the driven member 3.

[0093] For example, the rotation axis of the second rod 232 relative to the driven member 3, the rotation axis of the driven member 3, the rotation axis of the first rod 231 relative to the second rod 232, and the rotation axis of the first worm gear 22 may be arranged parallel to or non-parallel to each other.

[0094] Through the above arrangement, since the rotation axis of the rotation output end is staggered with the rotation axis of the driven part 3, the second rod body 232 is staggered with the rotation axis of the driven part 3 relative to the rotation axis of the driven part 3, so the rotation axis of the first worm gear 22 and the driven part 3, the driven part 3, the first rod body 231 and the second rod body 232 can form a structure similar to a hinged four-bar linkage mechanism.

[0095] Specifically, the first worm gear 22 and the rotating shaft of the driven member 3 are similar to the fixed rod in the hinge four-bar linkage mechanism, and the driven member 3, the first rod body 231 and the second rod body 232 are respectively similar to the three rotating rods in the hinge four-bar linkage mechanism.

[0096] In this way, when the driven part 3 needs to be rotated, the rotating driving part 1 can be started, so that the rotating driving part 1 drives the first worm gear 22 to rotate through the first worm 21, and the first worm gear 22 can drive the first rod body 231 to rotate, and then drive the second rod body 232 and the driven part 3 to rotate, thereby driving the driven part 3 to rotate and realizing the adjustment of the position of the driven part 3.

[0097] In some examples, when the transmission assembly 2 includes the second worm gear 25 and the second worm 24 , one end of the first rod body 231 is connected to the second worm gear 25 .

[0098] For example, one end of the first rod 231 and the second worm gear 25 may be connected together by screwing, welding, clamping, or the like.

[0099] For example, Figure 2 、 Figure 5 As shown, Figure 5 for Figure 2 Schematic diagram of the connection structure between the first rod body 231 and the connecting rod 26, the transmission assembly 2 also includes a connecting rod 26, the second worm gear 25 is connected to the connecting rod 26, and the connecting rod 26 is provided with a spline groove 261 on the side close to the first rod body 231. A spline shaft 2311 is provided at one end of the first rod body 231, and the spline shaft 2311 extends into the spline groove 261 and is engaged with the spline groove 261.

[0100] In some examples, such as Figure 2 As shown, the driven part 3 includes a camera 31, the transmission assembly 2 is arranged on the back of the camera 31, and along a direction perpendicular to the arrangement direction of the camera 31 and the transmission assembly 2, the second rod body 232 relative to the rotation axis of the driven part 3 and the rotation axis of the driven part 3 are respectively located on opposite sides of the camera 31, and the first opening is located on the side of the rotation axis of the driven part 3 that is away from the rotation axis of the second rod body 232 relative to the driven part 3.

[0101] In this way, after starting the rotary drive member 1, Figure 4 、 Figure 6 As shown, Figure 6 FIG3 is a schematic diagram of the external structure of the camera 31 when it is in a flipped state. The second rod 232 can push the camera 31 so that the camera 31 rotates around the rotation axis of the driven member 3, thereby extending out of the accommodating cavity 41. Figure 2 、 Figure 4 、 Figure 7 As shown, Figure 7 3 is a schematic diagram of the external structure of the camera 31 when it is in a retracted state. The second rod 232 can pull the camera 31 so that the camera 31 rotates around the rotation axis of the driven component 3 and extends into the accommodating cavity 41.

[0102] It should be noted that the back of the camera 31 refers to the side of the camera 31 opposite to the shooting direction of the camera 31.

[0103] In some embodiments, as Figure 8 、 Figure 9 As shown, Figure 8 is another exploded schematic diagram of the rotary drive assembly 20, Figure 9 FIG2 is a schematic diagram of another assembled state of the rotary drive assembly 20 , in which the transmission mechanism 23 includes a rack 233 . The rack 233 is connected to the driven member 3 and meshes with the first worm gear 22 .

[0104] It can be understood that the rack 233 is an arc-shaped rack 233 .

[0105] For example, the rack 233 may be bent in a direction toward the first worm gear 22 , or may be bent in a direction away from the first worm gear 22 .

[0106] Through the above arrangement, since the first worm gear 22 is engaged with the rack 233, after the rotary driving member 1 is started, the first worm gear 22 will rotate to drive the rack 233 and the driven member 3 to rotate around the rotation axis of the driven member 3, thereby driving the driven member 3 to rotate and realizing the adjustment of the position of the driven member 3.

[0107] In some examples, when the transmission assembly 2 includes the second worm gear 25 and the second worm 24 , the rack 233 is engaged with the second worm gear 25 .

[0108] In some examples, such as Figure 8 、 Figure 10 As shown, Figure 10 This is a schematic diagram of the external structure in which the operating panel 32 is in an extended state. The driven member 3 includes the operating panel 32, a fourth rod 33, a fifth rod 34 and a mounting plate 35. One end of the fourth rod 33 is hinged to the housing 4, and one end of the fifth rod 34 is hinged to the housing 4. The rotation axis of the fourth rod 33 relative to the housing 4 is coaxially arranged with the rotation axis of the fifth rod 34 relative to the housing 4.

[0109] The other end of the fourth rod 33 and the other end of the fifth rod 34 are both connected to the mounting plate 35. The operation panel 32 is connected to the mounting plate 35. The rack 233 is located on a side of the operation panel 32 close to the mounting plate 35 and is connected to the mounting plate 35.

[0110] Through the above arrangement, after starting the rotary drive member 1, the first worm 21 can apply thrust to the rack 233, so that the rack 233, the operating panel 32, the mounting plate 35, the fourth rod 33 and the fifth rod 34 all rotate around the rotation axis of the fourth rod 33 relative to the housing 4, thereby realizing the rotation of the operating panel 32.

[0111] Specifically, if Figure 10 、 Figure 11 As shown, Figure 11 for Figure 10 Another external structural diagram of the operation panel 32 in the extended state, at this time the operation panel 32 is in the extended state, such as Figure 12 As shown, Figure 12 for Figure 10 Schematic diagram of the external structure of the operation panel 32 in the retracted state. At this time, the operation panel 32 is in the retracted state.

[0112] In order to prevent the gravity acting on the operating panel 32 itself from driving the rack 233 and the first worm gear 22 to rotate, in some examples, a damping plate is provided at the hinge between one end of the fourth rod 33 and the housing 4 to increase the resistance encountered by the fourth rod 33 when rotating relative to the housing 4, thereby preventing the gravity acting on the operating panel 32 itself from driving the rack 233 and the first worm gear 22 to rotate, thereby ensuring the overall stability of the rotation drive structure.

[0113] In some examples, a damping sheet is provided at a hinged joint between one end of the fifth rod 34 and the housing 4 .

[0114] In some embodiments, as Figure 13 、 Figure 14 As shown, Figure 13 for Figure 1 Another exploded schematic diagram of the rotary drive assembly 20, Figure 14 for Figure 2 Another exploded view of the transmission assembly 2 shows the transmission mechanism 23, which includes a screw 234 and a sliding block 235. The screw 234 is connected to the first worm gear 22, with its rotation axis coaxial with the rotation axis of the first worm gear 22. The sliding block 235 has a mounting channel with threads formed therein, through which the screw 234 extends and is threadedly engaged.

[0115] like Figure 14 、 Figure 15 As shown, Figure 15 Figure 2 is a schematic diagram of the external structure of the third rod 238. The transmission mechanism 23 also includes a sliding plate 236 and a stopper 237. The sliding plate 236 is connected to one side of the sliding block 235 in the circumferential direction of the installation channel. The stopper 237 is fixed relative to the driven component 3 and is used to limit the circumferential movement of the sliding plate 236 along the installation channel.

[0116] The transmission mechanism 23 also includes a third rod 238. One end of the third rod 238 is rotatably connected to the sliding block 235, and the other end of the third rod 238 is rotatably connected to the driven member 3. The third rod 238 is offset from the rotation axis of the driven member 3.

[0117] For example, the rotation axis of the third rod 238 relative to the driven member 3 , the rotation axis of the driven member 3 , and the rotation axis of the third rod 238 relative to the sliding block 235 may be arranged parallel to or non-parallel to each other.

[0118] Through the above-mentioned setting, after starting the rotary drive member 1, the first worm gear 22 will rotate to drive the screw 234 to rotate. Since the limit member 237 can limit the circumferential movement of the sliding plate 236 along the installation channel, the sliding plate 236 is connected to the sliding block 235, and the screw 234 is screwed to the thread. Therefore, the sliding block 235 will move axially along the installation channel under the action of the screw 234 and the limit member 237.

[0119] In this case, the third rod body 238, the sliding block 235 and the driven part 3 can form a structure similar to a crank slider mechanism. Specifically, the sliding block 235 is similar to the slider in the crank slider mechanism, the third rod body 238 is similar to the connecting rod in the crank slider mechanism, and the driven part 3 is similar to the crank in the crank slider mechanism.

[0120] In this way, when the driven part 3 needs to be rotated, the rotating driving part 1 can be started, so that the rotating driving part 1 drives the first worm gear 22 to rotate through the first worm 21, and the first worm gear 22 can drive the sliding block 235 to slide through the screw 234, thereby driving the third rod body 238 and the driven part 3 to rotate, thereby driving the driven part 3 to rotate and realizing the adjustment of the position of the driven part 3.

[0121] In some examples, such as Figure 13 、 Figure 15 As shown, the driven part 3 includes a camera 31, the transmission assembly 2 is arranged on the back of the camera 31, and the axial direction of the screw 234 is consistent with the arrangement direction of the camera 31 and the transmission assembly 2.

[0122] Along a direction perpendicular to the arrangement direction of the camera 31 and the transmission assembly 2, the third rod body 238 is located on opposite sides of the camera 31 relative to the rotation axis of the driven part 3 and the rotation axis of the driven part 3, respectively, and the first opening is located on the side of the rotation axis of the driven part 3 that is away from the rotation axis of the second rod body 232 relative to the driven part 3.

[0123] In this way, after starting the rotating drive member 1, the screw 234 can push the sliding block 235 to move toward or away from the camera 31, thereby driving the third rod body 238 to move toward or away from the camera 31, thereby pushing or pulling the camera 31, causing the camera 31 to rotate around the rotating axis of the driven member 3, and then extend out or extend into the accommodating cavity 41.

[0124] Based on the above, in some examples, the screw rod 234 is connected to the second worm gear 25 and partially extends out of the third mounting slot 56 , and the sliding block 235 is threadedly connected to the portion of the screw rod 234 extending out of the third mounting slot 56 .

[0125] The limiting member 237 includes an abutting plate 2371 , one end of the abutting plate 2371 is connected to the side wall of the third installation slot 56 , and the other end of the abutting plate 2371 is spaced apart from the side wall of the third installation slot 56 .

[0126] The sliding plate 236 has a first surface and a second surface adjacent to each other. The first surface contacts the abutting plate 2371 , and the second surface contacts the sidewall of the third mounting groove 56 . The sliding block 235 is connected to the second surface.

[0127] Through the above-mentioned arrangement, during the rotation of the screw 234, since the first surface contacts the abutment plate 2371 and the second surface contacts the side wall of the third mounting groove 56, when the sliding block 235 and the limit plate rotate along the circumference of the screw 234, they will be blocked by the abutment plate 2371 and the side wall of the third mounting groove 56. In this way, as the screw 234 continues to rotate, the sliding block 235 can only move along the axial direction of the screw 234, thereby pushing or pulling the driven part 3 to rotate through the third rod body 238.

[0128] In other examples, such as Figure 14 、 Figure 15 As shown, the screw 234 is connected to the second worm gear 25 and is located in the third mounting groove 56. The side wall of the third mounting groove 56 is provided with a fourth opening 57, the sliding block 235 is passed through the fourth opening 57, and the mounting channel is located in the third mounting groove 56.

[0129] The portion of the sliding block 235 extending into the third mounting slot 56 is screwed to the screw rod 234 , and the portion of the sliding block 235 extending out of the third mounting slot 56 is connected to the third rod 238 . Along the circumference of the screw rod 234 , both opposite sides of the fourth opening 57 are in contact with the sliding block 235 .

[0130] It can be understood that, in the above case, the limiting member 237 is a side wall of the third installation groove 56 .

[0131] Through the above-mentioned arrangement, during the rotation of the screw 234, the two opposite sides of the fourth opening 57 are in contact with the sliding block 235. Therefore, when the sliding block 235 and the limit plate rotate along the circumference of the screw 234, they will be blocked by the side wall of the third mounting groove 56. In this way, as the screw 234 continues to rotate, the sliding block 235 can only move along the axial direction of the screw 234, thereby pushing or pulling the driven part 3 to rotate through the third rod body 238.

[0132] In some examples, such as Figure 13 As shown, the side wall of the accommodating cavity 41 is provided with a limiting groove 42, and the direction of the opening of the limiting groove 42 is consistent with the axial direction of the rotating shaft of the driven member 3. Along the circumference of the rotating shaft of the driven member 3, the limiting groove 42 has a first side wall and a second side wall.

[0133] The driven member 3 is provided with a stopper 36, which partially extends into the stopper groove 42. As the driven member 3 rotates to extend out of the accommodating cavity 41, the stopper 36 moves toward the first side wall. As the driven member 3 rotates to extend into the accommodating cavity 41, the stopper 36 moves toward the second side wall.

[0134] For example, the number of the limiting grooves 42 may be one or more, and correspondingly, the number of the limiting blocks 36 may be one or more, with one limiting block 36 extending into one limiting groove 42 .

[0135] By setting the limiting groove 42 and the limiting block 36, the rotation angle of the driven part 3 can be limited. For example, in the process of the driven part 3 extending out of the accommodating cavity 41, as the driven part 3 continues to rotate, the limiting block 36 will gradually move toward the direction close to the first side wall until it contacts the first side wall. At this time, the first side wall will block the limiting block 36, thereby limiting the driven part 3 from continuing to rotate.

[0136] In this way, by setting the limit groove 42 and the limit block 36, the rotation range of the driven part 3 can be set to a more appropriate size to avoid the driven part 3 from rotating too much, thereby avoiding the driven part 3 from colliding with other objects, or the driven part 3 from colliding with the transmission mechanism 23 during rotation, etc., thereby protecting the driven part 3.

[0137] In some examples, such as Figure 8 、 Figure 16 As shown, Figure 16 for Figure 8 Schematic diagram of the exploded structure of the transmission assembly 2, the transmission assembly 2 also includes a protective member 27, the protective member 27 abuts against the first worm gear 22, and the input end of the transmission mechanism 23 is connected to the protective member 27.

[0138] When the first worm gear 22 rotates, the friction force between the protection member 27 and the first worm gear 22 is static friction force.

[0139] With the above arrangement, when the external force applied to the driven member 3 is too large, for example, when a user bumps into the driven member 3 , the driven member 3 rotates and drives the transmission mechanism 23 to move.

[0140] Since the protective member 27 is not connected to the first worm gear 22, the friction between the protective member 27 and the first worm gear 22 will gradually increase and exceed the maximum static friction between the protective member 27 and the first worm gear 22, and then be converted into a sliding friction of a fixed magnitude. At this time, the protective member 27 will rotate under the action of the transmission mechanism 23, while the first worm gear 22 can still remain stationary, or rotate slowly under the action of the sliding friction.

[0141] In this way, the provision of the protective member 27 can prevent the first worm gear 22 from rotating rapidly when the external force applied to the driven member 3 is too large, thereby protecting the rotary driving member 1 and preventing the rotary driving member 1 from being damaged.

[0142] It should be noted that the sliding friction force is slightly smaller than the maximum static friction force.

[0143] In some examples, when the transmission mechanism 23 includes a first rod 231 and a second rod 232, the protective member 27 is disposed within the accommodating cavity 41. The protective member 27 includes an elastic member and a friction plate. The friction plate contacts the first worm gear 22. One end of the elastic member is connected to one end of the first rod 231, and the other end of the elastic member is connected to the friction plate. The elastic member is elastically supported between the friction plate and the housing 4.

[0144] Illustratively, the elastic member may be a spring, an elastic plate, an elastic sheet, etc.

[0145] In this way, the elastic member can apply pressure to the friction plate, thereby pressing the friction plate onto the first worm gear 22. When the first worm gear 22 rotates, the elastic member can drive the friction plate to rotate, thereby driving the first rod body 231 and the driven member 3 to rotate.

[0146] When the driven member 3 is subjected to a large external force, the friction plate can rotate relative to the second worm gear 25 , thereby preventing the second worm gear 25 from rotating and damaging the rotary driving member 1 .

[0147] In some examples, when the transmission mechanism 23 includes a rack 233 , the protective member 27 further includes a gear, which is sleeved on the elastic member and meshes with the rack 233 .

[0148] In some examples, the rotary drive assembly 20 further includes a controller, which is electrically connected to the rotary drive member 1 . The controller is configured to control the start or shut down of the rotary drive member 1 according to instruction information issued by the user, thereby controlling the rotation angle of the driven member 3 .

[0149] For example, vehicle 100 is equipped with a rollover control button, and the controller is electrically connected to both the rollover control button and the retraction control button. When the user presses the rollover control button, the controller activates the rotary drive member 1, causing the driven member 3 to rotate and gradually extend out of the accommodating cavity 41. When the user releases the rollover control button, the controller deactivates the rotary drive member 1, and the driven member 3 stops rotating. This allows the rotation angle of the driven member 3 to be adjusted, and the user can release the rollover control button when the driven member 3 has rotated to a desired angle, allowing the driven member 3 to rotate to any desired angle.

[0150] Alternatively, the vehicle 100 is provided with a plurality of control buttons, and one control button corresponds to a fixed rotation angle of the driven member 3 , so that the user can control the driven member 3 to rotate to a plurality of different positions through the plurality of control buttons.

[0151] In some examples, the rotary drive member 1 includes a motor and a current sensor. The current sensor is used to detect the current flowing through the motor and is electrically connected to the motor and a controller. When the stop block 36 contacts the first side wall or the second side wall, the driven member 3 cannot rotate, causing the motor to stall. This increases the current flowing through the motor. Upon detecting excessive current through the current sensor, the controller stops the motor, thereby protecting the motor and preventing damage.

[0152] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
