Description

Technical Field

[0001] This application relates to the field of cleaning machine technology, and more particularly to a cleaning device. Background Technology

[0002] A floor scrubber is a machine used to clean floors. It can replace manual mopping and clean floors efficiently. A floor scrubber typically consists of a chassis for cleaning the floor and a body that is hinged to the chassis.

[0003] In related technologies, a connecting component is added to the floor scrubber, rotatably connected to the chassis, and the machine body is rotatably connected to the connecting component. This gives the machine body two degrees of rotational freedom. The machine body can switch between standing and non-standing positions relative to the chassis via one degree of rotational freedom, and between returning and non-returning positions relative to the connecting component via the other degree of rotational freedom, thereby improving the flexibility of the floor scrubber. However, when storing the floor scrubber, the high rotational flexibility of the machine body relative to the connecting component makes it difficult to keep the machine body upright, causing it to easily tip over, rotate, or tilt, making the machine body prone to damage. Summary of the Invention

[0004] The purpose of this application is to provide a cleaning device that solves the technical problem that cleaning equipment is not easy to fix when the machine body does not need to rotate.

[0005] To achieve the above objectives, the technical solution adopted in this application embodiment is: a cleaning device, including a chassis, an adapter, a locking mechanism, and a body.

[0006] The chassis is used to clean the surface to be cleaned; the adapter is rotatably mounted on the chassis about a first direction; the locking mechanism is disposed within the adapter, and the locking mechanism includes a drive assembly and a locking tongue; the body is provided with a limiting structure, and the body is rotatably mounted on the adapter about a second direction, the first direction and the second direction intersect, the axial direction of the body intersects the second direction, and the body is configured to have a locked state and an unlocked state in response to its angle with the surface to be cleaned; wherein, when the body is in the locked state, the locking tongue is driven by the drive assembly to insert into the limiting structure; when the body is in the unlocked state, the locking tongue is driven by the drive assembly to disengage from the limiting structure.

[0007] The beneficial effects of the cleaning device provided in this application are as follows: when the machine body is in the locked state, the locking tongue is driven by the drive component to insert into the limiting structure; the relative position of the machine body and the adapter can be fixed to prevent the machine body from rotating relative to the adapter in a second direction, thereby reducing the risk of the machine body tipping over or being damaged; and when the machine body is in the unlocked state, the locking tongue is driven by the drive component to disengage from the limiting structure, without affecting the normal operation of the cleaning equipment.

[0008] In some embodiments, the drive assembly includes a push group and a first elastic member. When the body is in a locked state, the first elastic member or the push group drives the latch to insert into the limiting structure; when the body is in an unlocked state, the first elastic member drives the latch to disengage from the limiting structure.

[0009] In some embodiments, when the body is in a locked state, the first elastic element is in a compressed state; when the body is in an unlocked state, the first elastic element is in a free state.

[0010] In some embodiments, the push assembly includes a first drive member and a second drive member, both of which are slidably disposed within the adapter. The second drive member can push the first drive member to slide, and the first drive member is connected to the locking tongue.

[0011] When the body is in the locked state, one end of the second drive member abuts against the limiting surface on the chassis, and the other end abuts against the first drive member, and the locking tongue presses against the first elastic member; when the body is in the unlocked state, one end of the second drive member disengages from the limiting surface, and the other end of the second drive member abuts against the first drive member.

[0012] In some embodiments, the first driving member is provided with a driving ramp, and the second driving member abuts against the driving ramp; and / or, the second driving member is provided with a driving ramp, and the first driving member abuts against the driving ramp;

[0013] The driving inclined surface includes a first end and a second end that are disposed opposite to each other. The first end is closer to the locking tongue than the second end, and the first end is closer to the limiting surface than the second end.

[0014] In some embodiments, the push assembly further includes a second elastic member, one end of which is connected to the first drive member, and the other end of which is connected to the locking tongue.

[0015] In some embodiments, the push assembly includes a first connector and a rotating member, the rotating member being rotatably disposed on the adapter, and the rotating member including a third end and a fourth end located on both sides of its rotation axis, the third end abutting against the locking tongue, and the first connector being connected to the fourth end and the chassis respectively.

[0016] When the body is in the locked state, the first connector drives the rotating member to rotate, causing the third end to push the locking tongue into the limiting structure, and the locking tongue presses against the first elastic member; when the body is in the unlocked state, the first elastic member drives the locking tongue to disengage from the limiting structure.

[0017] In some embodiments, the first connector includes a first pull cord, which is connected to the fourth end and the chassis respectively. When the body is in a locked state, the distance between the connection point of the first pull cord and the fourth end and the connection point of the first pull cord and the chassis is equal to the length of the first pull cord. When the body is in an unlocked state, the distance between the connection point of the first pull cord and the fourth end and the connection point of the first pull cord and the chassis is less than the length of the first pull cord.

[0018] In some embodiments, the body has a stop surface. When the body is in a locked state, the first connecting member can drive the rotating member to rotate until the fourth end is away from the stop surface. When the body is in an unlocked state, under the drive of the first elastic member, the rotating member can rotate until the fourth end abuts against the stop surface.

[0019] In some embodiments, the adapter is provided with a receiving cavity and a first through hole communicating with the receiving cavity, and the locking tongue and the first elastic member are both received in the receiving cavity; when the body is in a locked state, the limiting structure is aligned with the first through hole, and the locking tongue passes through the first through hole and is inserted into the limiting structure.

[0020] In some embodiments, the latch includes an insertion portion and a stop portion. In the radial direction of the first through hole, the stop portion protrudes from the insertion portion. The first elastic member is sleeved on the insertion portion, and one end of the first elastic member abuts against the stop portion, while the other end of the first elastic member abuts against the inner wall of the receiving cavity.

[0021] In some embodiments, when the body is in the locked state, the first elastic element is in the unloaded state, and when the body is in the unlocked state, the first elastic element is in the compressed state.

[0022] In some embodiments, the adapter has a first chamber, a second chamber, a second through hole communicating with the first chamber, and a third through hole communicating with the second chamber; the push assembly includes a third drive member, a third elastic member, and a second connector, wherein the third drive member and the third elastic member are both housed in the second chamber, the latch and the first elastic member are both housed in the first chamber, and the second connector is connected to the third drive member and the latch respectively;

[0023] When the body is in the locked state, a portion of the third driving member passes through the third through hole and abuts against the limiting surface on the chassis, and a portion of the third driving member is housed in the second chamber. The first elastic member drives the locking tongue to pass through the second through hole and insert into the limiting structure. When the body is in the unlocked state, the third driving member disengages from the limiting surface, and the third elastic member drives the third driving member to disengage the locking tongue from the limiting structure, and the locking tongue presses against the first elastic member.

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0056] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0058] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0059] A floor scrubber is a machine used to clean floors. It can replace manual mopping and clean floors efficiently. A floor scrubber typically consists of a chassis for cleaning the floor and a body that is hinged to the chassis.

[0060] In related technologies, a connecting component is added to the floor scrubber, rotatably connected to the chassis, and the machine body is rotatably connected to the connecting component. This gives the machine body two degrees of rotational freedom. The machine body can switch between standing and non-standing positions relative to the chassis via one degree of rotational freedom, and between returning and non-returning positions relative to the connecting component via the other degree of rotational freedom, thereby improving the flexibility of the floor scrubber. However, when storing the floor scrubber, the high rotational flexibility of the machine body relative to the connecting component makes it difficult to keep the machine body upright, causing it to easily tip over, rotate, or tilt, making the machine body prone to damage.

[0061] In view of the above problems, this application provides a cleaning device to solve the technical problem that the cleaning device is not easy to fix when the machine body does not need to rotate.

[0062] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0063] Please refer to Figures 1 to 10 This application provides a cleaning device, including a chassis 1, an adapter 2, a locking mechanism 3, and a body 4.

[0064] The chassis 1 is used to clean the surface to be cleaned; the adapter 2 is rotatably mounted on the chassis 1 about a first direction; the locking mechanism 3 is located inside the adapter 2, and the locking mechanism 3 includes a drive assembly 31 and a locking tongue 32; the body 4 is provided with a limiting structure 41, and the body 4 is rotatably mounted on the adapter 2 about a second direction, the first direction and the second direction intersect, the axis of the body intersects the second direction, and the body 4 is configured to have a locked state and an unlocked state in response to its angle with the surface to be cleaned; wherein, when the body 4 is in the locked state, the locking tongue 32 is driven by the drive assembly 31 to insert into the limiting structure 41 (e.g., ...). Figures 1 to 6 (as shown); when the body 4 is in the unlocked state, the locking tongue 32 is driven by the drive component 31 to disengage from the limiting structure 41 (as shown). Figures 7 to 9 (As shown).

[0065] The chassis 1 supports cleaning components (such as a cleaning cloth) at its bottom. The chassis 1 is connected to the main body 4 via an adapter 2. The adapter 2 is rotatably connected to the chassis 1, allowing the adapter 2 and the main body 4 to be in an upright position relative to the chassis 1 (e.g., ...). Figure 1 As shown), tilt state (as shown) Figure 7 (as shown) and lying flat (as shown) Figure 10 (As shown) allows for flexible switching. Furthermore, since the adapter 2 and the fuselage 4 are rotatably connected, the fuselage 4 can also rotate relative to the adapter 2 in the aforementioned upright, tilted, and lying-down states. Further reference... Figure 1 This indicates that when the adapter 2 is in an upright position, the fuselage 4 is also in an upright position. Figure 5 , Figure 13 The illustration shows that when the adapter 2 is in an upright position, the body 4 rotates relative to the adapter 2 and is tilted. It can be understood that the body 4 is configured to have locked and unlocked states in response to its angle with the surface to be cleaned: when the body 4 is tilted relative to the surface to be cleaned (the adapter 2 and the body 4 as a whole are tilted or lying flat relative to the chassis 1), the body 4 is in the unlocked state, and the body 4 can rotate relative to the adapter 2. The cleaning components on the chassis 1 can twist left and right relative to the body 4 to improve flexibility. When the body 2 is upright relative to the surface to be cleaned (the adapter 2 and the body 4 as a whole are upright relative to the chassis 1), the body 4 is in the locked state, and the cleaning components on the chassis 1 will no longer twist left and right relative to the body 4.

[0066] The surface to be cleaned can be the floor, countertop, or desktop.

[0067] Please refer to Figure 12In some embodiments, the adapter 2 includes a first connecting part 29 and a second connecting part 210. The first connecting part 29 is rotatably disposed on the chassis 1, and the second connecting part 210 is rotatably disposed through the body 4, or the second connecting part 210 is rotatably sleeved on the body 4. The first connecting part 29 has a first fitting slope, the orientation of which is parallel to a second direction. The body 4 has a second fitting slope, the orientation of which is parallel to a second direction.

[0068] For ease of description, the first direction X is defined as parallel to the axis of rotation of the adapter 2 relative to the chassis 1. Generally, the first direction X is parallel to the surface to be cleaned. The second direction Y is defined as parallel to the axis of rotation of the adapter 2 and the body 4 relative to each other (the axial direction of the second connecting part 210). The second direction Y is not perpendicular to the first direction X and the included angle is fixed. When the adapter 2 rotates relative to the chassis 1, the axial direction of the second connecting part 210, i.e., the second direction, will change. The outer wall of the body 4 is generally columnar. The axial direction corresponding to the outer wall of the body 4 (referred to as the "axial direction of the body 4") is defined as the axial direction L. The second direction Y is not parallel to the axial direction L. As the body 4 rotates relative to the adapter 2, the direction of the axial direction L changes, and the included angle between the second direction Y and the axial direction L changes. When both the adapter 2 and the body 4 are in an upright state relative to the base 1, the axial direction L is parallel to the direction of gravity and perpendicular to the first direction X. When the adapter 2 is upright relative to the base 1 and the fuselage 4 is tilted relative to the base 1, the axis of the adapter 2 is parallel to the direction of gravity, while the axis L of the fuselage 4 is not parallel to the direction of gravity. Therefore, it can be understood that when the fuselage 4 and the adapter 2 are not fixed, the fuselage 4 is prone to rotate relative to the adapter 2 to a state where the axis L is not parallel to the direction of gravity, thus causing it to tilt or fall over.

[0069] The cleaning device provided in this embodiment is designed so that the main body 4 can stand stably when the cleaning device is not in operation. In this embodiment, a locking mechanism 3 is provided in the adapter 2 and a limiting structure 41 is provided in the main body 4. When the main body 4 is in the locked state, the locking tongue 32 is driven by the driving component 31 to insert into the limiting structure 41. This can fix the relative position of the main body 4 and the adapter 2 to prevent the main body 4 from rotating relative to the adapter 2 in the second direction, thereby reducing the risk of the main body 4 tipping over or being damaged. When the main body 4 is in the unlocked state, the locking tongue 32 is driven by the driving component 31 to disengage from the limiting structure 41, without affecting the normal operation of the cleaning device.

[0070] It should be noted that when the fuselage 4 is in the locked state, the limiting structure 41 on the fuselage 4 is aligned with the locking tongue 32, allowing the locking tongue 32 to be inserted into the limiting structure 41. The locking process of the fuselage 4 is as follows: the adapter 2 rotates around the first direction, making the axis of the fuselage 4 parallel to the direction of gravity; if the limiting structure 41 on the fuselage 4 is aligned with the locking tongue 32, the locking tongue 32 will be driven by the drive component 31 to insert into the limiting structure 41; if the limiting structure 41 on the fuselage 4 is not aligned with the locking tongue 32, the fuselage 4 rotates around the second direction until the limiting structure 41 is aligned with the locking tongue 32, allowing the locking tongue 32 to be inserted into the limiting structure 41. At this time, the fuselage 4 can no longer rotate relative to the adapter 2.

[0071] The actions in the above process (such as the adapter 2 rotating around the first direction and the body 4 rotating around the second direction) can be completed manually by the user or automatically by the control system in the cleaning device.

[0072] In the cleaning device of the present application embodiment, the limiting structure 41 is a slot formed on the body 4.

[0073] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the fuselage 4 is provided with multiple limiting structures 41, which are spaced apart around the second direction. When the fuselage 4 rotates relative to the adapter 2, the locking tongue 32 can align with different limiting structures 41, allowing the locking tongue 32 to engage with different limiting structures 41, thus giving the fuselage 4 multiple locking states. Furthermore, in different locking states, the tilt direction and / or tilt angle of the fuselage 4 relative to the direction of gravity are different.

[0074] It should be noted that in the locked state, fuselage 4 is in an upright position, and the axis L of fuselage 4 is parallel to the vertical direction (e.g., Figure 1 (as shown), or the axial direction of the fuselage 4 is tilted relative to the vertical direction (e.g. Figure 5 As shown), the tilt of the body 4 is determined by the angle of rotation of the adapter 2 around the first direction. In the unlocked state, the latch 32 disengages from the limiting structure 41, and the body 4 can rotate relative to the adapter 2. At this time, the axial direction L of the body 4 is tilted relative to the vertical direction (as shown). Figure 7 and Figure 10 As shown), the degree of tilt of the fuselage 4 is determined by the angle of rotation of the adapter 2 around the first direction and the angle of rotation of the fuselage 4 around the second direction.

[0075] In some embodiments, the drive component 31 includes a push group 312 and a first elastic member 311. When the body 4 is in a locked state, the first elastic member 311 or the push group 312 drives the locking tongue 32 to insert into the limiting structure 41. When the body 4 is in an unlocked state, the first elastic member 311 drives the locking tongue 32 to disengage from the limiting structure 41.

[0076] exist Figures 1 to 10 In the embodiments shown, and Figures 11 to 16 In the embodiment shown, when the body 4 is in the locked state, the first elastic element 311 is in the compressed state; when the body 4 is in the unlocked state, the first elastic element 311 is in the unloaded state.

[0077] When the body 4 is in the locked state, the push assembly 312 pushes the latch 32 into the limiting structure 41, the latch 32 presses against the first elastic member 311, and the elastic force generated by the first elastic member 311 is applied to the latch 32. When the body 4 is in the unlocked state, the first elastic member 311 returns to its natural state. During the process of the first elastic member 311 returning to its natural state, the elastic force generated by the first elastic member 311 can drive the latch 32 to move out of the limiting structure 41. With the above settings, the structure of the drive assembly 31 can be simplified.

[0078] Please refer to Figure 2 and Figure 3 In some embodiments, the push assembly 312 includes a first drive member 3121 and a second drive member 3122. Both the first drive member 3121 and the second drive member 3122 are slidably disposed in the adapter 2. The second drive member 3122 can push the first drive member 3121 to slide. The first drive member 3121 is connected to the locking tongue 32.

[0079] When the body 4 is in the locked state, the adapter 2 rotates relative to the chassis 1, causing the second drive member 3122 to move until one end of the second drive member 3122 abuts against the limiting surface 11 on the chassis 1, and the other end abuts against the first drive member 3121. This causes the second drive member 3122 to push the first drive member 3121 to move, and the first drive member 3121 to push the locking tongue 32, causing the locking tongue 32 to insert into the limiting structure 41, and the locking tongue 32 to compress the first elastic member 311; Reference Figure 9 When the body 4 is in the unlocked state, the adapter 2 rotates relative to the chassis 1, causing the second drive member 3122 to move until one end of the second drive member 3122 is disengaged from the limiting surface 11, and the other end of the second drive member 3122 abuts against the first drive member 3121. The first elastic member 311 drives the locking tongue 32 to disengage from the limiting structure 41, so that the locking tongue 32 pushes the first drive member 3121, and the first drive member 3121 pushes the second drive member 3122 to move.

[0080] By adopting the above technical solution, the thrust exerted by the limiting surface 11 on the second driving member 3122 can be converted into the thrust exerted by the first driving member 3121 on the locking tongue 32. That is, when the body 4 is in the locked state, one end of the second driving member 3122 abuts against the limiting surface 11 on the chassis 1, and the other end abuts against the first driving member 3121, so that the second driving member 3122 can push the first driving member 3121 to slide, so that the first driving member 3121 pushes the locking tongue 32 to overcome the resistance of the first elastic member 311 and insert it into the limiting structure 41.

[0081] It should be noted that in the above embodiments, the sliding direction of the first driving member 3121 is parallel to the extending direction of the limiting structure 41. For example, in Figure 2 and Figure 3 In the illustrated embodiment, the extending direction of the limiting structure 41 is parallel to the second direction, and therefore the sliding direction of the first driving member 3121 is parallel to the second direction. The sliding direction of the second driving member 3122 can be set according to the direction in which the second driving member 3122 is positioned relative to the limiting surface 11 on the chassis 1, and the sliding direction of the second driving member 3122 is parallel to the direction in which the second driving member 3122 is positioned relative to the limiting surface 11. For example, in Figure 1 and Figure 2 In the embodiment shown, the direction in which the second driving member 3122 is positioned opposite the limiting surface 11 is parallel to the first direction, and the sliding direction of the second driving member 3122 is parallel to the first direction.

[0082] In some embodiments, the sliding direction of the first driving member 3121 intersects the sliding direction of the second driving member 3122, thereby converting the thrust applied by the limiting surface 11 to the second driving member 3122 into the thrust applied by the first driving member 3121 to the locking tongue 32, and also changing the direction of the force. For example, Figures 1 to 3 In the illustrated embodiment, the thrust applied by the limiting surface 11 to the second driving member 3122 is parallel to the first direction, the sliding direction of the second driving member 3122 is parallel to the first direction, the sliding direction of the first driving member 3121 is parallel to the extension direction of the limiting structure 41, and the thrust applied by the first driving member 3121 to the locking tongue 32 is parallel to the extension direction of the limiting structure 41. Furthermore, the intersecting sliding directions of the first driving member 3121 and the second driving member 3122 further reduces the movement space of the pushing assembly 312, thereby reducing the volume of the driving component 31.

[0083] Please refer to Figure 3 and Figure 4In some embodiments, the first driving member 3121 is provided with a driving ramp 31221, and the second driving member 3122 abuts against the driving ramp 31221; and / or, the second driving member 3122 is provided with a driving ramp 31221, and the first driving member 3121 abuts against the driving ramp 31221. The driving ramp 31221 includes a first end 31222 and a second end 31223 disposed opposite to each other. The first end 31222 is closer to the locking tongue 32 than the second end 31223, and the first end 31222 is closer to the limiting surface 11 than the second end 31223.

[0084] By adopting the above technical solution, the second driving member 3122 abuts against the driving inclined surface 31221 and / or the first driving member 3121 abuts against the driving inclined surface 31221. When the second driving member 3122 pushes the first driving member 3121 to slide, the sliding directions of the first driving member 3121 and the second driving member 3122 are arranged to cross each other.

[0085] Please refer to Figure 3 In some embodiments, the push assembly 312 further includes a second elastic member 3123, one end of which is connected to the first drive member 3121, and the other end of which is connected to the locking tongue 32.

[0086] In the above embodiment, the second elastic element 3123 acts as a buffer. During the locking process of the body 4, the first driving element 3121 compresses the second elastic element 3123, causing the thrust exerted by the second elastic element 3123 on the locking tongue 32 to increase slowly, so that the locking tongue 32 can move slowly and stably insert into the limiting structure 41. During the unlocking process of the body 4, the first elastic element 311 drives the locking tongue 32 to move, and the locking tongue 32 compresses the second elastic element 3123, causing the thrust exerted by the second elastic element 3123 on the first driving element 3121 to increase slowly, so that the first driving element 3121 and the second driving element 3122 can move slowly. By setting the second elastic element 3123, the stability of the locking mechanism 3 can be enhanced, thereby reducing the risk of damage to the locking mechanism 3 and extending the service life of the locking mechanism 3.

[0087] Please refer to Figure 11 and Figure 12 In some embodiments, the push assembly 312 includes a first connecting member 3124 and a rotating member 3125. The rotating member 3125 is rotatably mounted on the adapter 2, and the rotating member 3125 includes a third end 31251 and a fourth end 31252 located on both sides of its rotation axis. The third end 31251 abuts against the locking tongue 32, and the first connecting member 3124 is connected to the fourth end 31252 and the chassis 1, respectively. When the body 4 is in the locked state (e.g. Figure 11 and Figure 12 , Figure 13 and Figure 14The first connecting member 3124 drives the rotating member 3125 to rotate, causing the third end 31251 to push the locking tongue 32 into the limiting structure 41, and the locking tongue 32 presses the first elastic member 311; when the body 4 is in the unlocked state (e.g. Figure 15 and Figure 16 The first elastic element 311 drives the locking tongue 32 to disengage from the limiting structure 41.

[0088] In the above embodiment, when the body 4 is in the locked state, the first connecting member 3124 is tightened and drives the rotating member 3125 to rotate, so that the third end 31251 pushes the locking tongue 32 to overcome the resistance of the first elastic member 311 and insert into the limiting structure 41; when the body 4 is in the unlocked state, the first connecting member 3124 is relaxed, and the first elastic member 311 returns to its natural state and drives the locking tongue 32 to disengage from the limiting structure 41.

[0089] Please refer to Figure 11 , Figure 12 , Figure 15 and Figure 16 In some embodiments, the first connector 3124 includes a first pull rope, which is connected to the fourth end 31252 and the chassis 1 respectively. When the body 4 is in the locked state, the distance between the connection point of the first pull rope and the fourth end 31252 and the connection point of the first pull rope and the chassis 1 is equal to the length of the first pull rope, so that the first pull rope is taut and drives the rotating member 3125 to rotate. When the body 4 is in the unlocked state, the distance between the connection point of the first pull rope and the fourth end 31252 and the connection point of the first pull rope and the chassis 1 is less than the length of the first pull rope, so that the second pull rope is relaxed and the force exerted by the first pull rope on the rotating member 3125 disappears.

[0090] In other embodiments, the first connecting member 3124 includes a hinged first connecting rod and a second connecting rod. The end of the first connecting rod opposite to the second connecting rod is rotatably connected to a fourth end 31252, and the end of the second connecting rod opposite to the first connecting rod is rotatably connected to the chassis 1. When the body 4 is in the locked state, the distance between the hinge point of the first connecting rod and the fourth end 31252 and the hinge point of the second connecting rod and the chassis 1 is a first distance. When the body 4 is in the unlocked state, the distance between the hinge point of the first connecting rod and the fourth end 31252 and the hinge point of the second connecting rod and the chassis 1 is a second distance. The sum of the distance between the hinge point of the first connecting rod and the second connecting rod, the distance between the hinge point of the first connecting rod and the fourth end 31252, and the distance between the hinge point of the first connecting rod and the second connecting rod and the hinge point of the second connecting rod and the chassis 1 is a third distance. The second distance is less than the first distance, and the first distance is equal to the third distance. When the body 4 is in the locked state, the first connecting rod and the second connecting rod are parallel to each other, so that the first connecting member 3124 is taut, and the first connecting rod pulls the fourth end 31252, and the third end 31251 pushes the locking tongue 32 into the limiting structure 41. When the body 4 is in the unlocked state, the first connecting rod and the second connecting rod rotate relative to each other to cross, so that the first connecting member 3124 is relaxed, thereby reducing the pulling force of the first connecting rod on the fourth end 31252, so that the rotating member 3125 rotates under the drive of the first elastic member 311 until the fourth end 31252 abuts against the stop surface 42.

[0091] In some embodiments, the adapter 2 is provided with a receiving cavity 21 and a first through hole 22 communicating with the receiving cavity 21. The locking tongue 32 and the first elastic member 311 are both received in the receiving cavity 21. When the body 4 is in the locked state, the limiting structure 41 is aligned with the first through hole 22, and the locking tongue 32 passes through the first through hole 22 and is inserted into the limiting structure 41.

[0092] In the above embodiments, the accommodating cavity 21 and the first through hole 22 can define the position of the locking tongue 32 and guide the movement direction of the locking tongue 32.

[0093] Please refer to Figure 4 ,exist Figures 1 to 10In the illustrated embodiment, the accommodating cavity 21 includes a first cavity 211 and a second cavity 212 that are interconnected. The extending direction of the first cavity 211 is parallel to the sliding direction of the first driving member 3121, and the extending direction of the second cavity 212 is parallel to the sliding direction of the second driving member 3122. The first through hole 22 communicates with the first cavity 211, and the adapter 2 is also provided with a fourth through hole 27 communicating with the second cavity 212. The locking tongue 32, the first elastic member 311, the second elastic member 3123, and the first driving member 3121 are all housed in the first cavity 211. A portion of the second driving member 3122 is housed in the first cavity 211, and another portion of the second driving member 3122 is housed in the second cavity 212. The other portion of the second driving member 3122 can pass through the fourth through hole 27 to protrude from the accommodating cavity 21. The first cavity 211 can limit the position of the first driving member 3121 and guide the sliding direction of the first driving member 3121; the first cavity 211 and the fourth through hole 27 can limit the position of the second driving member 3122 and guide the sliding direction of the second driving member 3122.

[0094] Please refer to Figure 12 ,exist Figures 11 to 16 In the illustrated embodiment, the receiving cavity 21 is a cavity with one end open and the other end closed, and the first through hole 22 is opened at the closed end. The rotating member 3125 is disposed at the opening of the receiving cavity 21 so that the rotating member 3125 supports the locking tongue 32 and can prevent the locking tongue 32 from disengaging from the receiving cavity 21.

[0095] Please refer to Figure 12 In some embodiments, the body 4 has a stop surface 42. When the body 4 is in a locked state, the first connecting member 3124 can drive the rotating member 3125 to rotate to the fourth end 31252 away from the stop surface 42. When the body 4 is in an unlocked state, under the drive of the first elastic member 311, the rotating member 3125 can rotate to the fourth end 31252 to abut against the stop surface 42.

[0096] It should be noted that the receiving cavity 21 is a cavity with one end open and the other end closed, and the first through hole 22 is opened at the closed end. The third end 31251 of the rotating member 3125 is located at the opening of the receiving cavity 21, and the third end 31251 of the rotating member 3125 supports the locking tongue 32, which can prevent the locking tongue 32 from disengaging from the receiving cavity 21. If the body 4 is in the unlocked state, and the rotation angle of the rotating member 3125 is too large, the rotating member 3125 will rotate until the third end 31251 no longer contacts the locking tongue 32, causing the locking tongue 32 to lose support and disengage from the receiving cavity 21. The above embodiment can limit the final position of the rotating member 3125 during the unlocking process of the body 4 by setting the stop surface 42, and can limit the position of the rotating member 3125 to avoid the third end 31251 no longer supporting the locking tongue 32 due to the large rotation angle of the rotating member 3125.

[0097] Please refer to Figure 4 In some embodiments, the locking tongue 32 includes an insertion portion 321 and a stop portion 322. In the radial direction of the first through hole 22, the stop portion 322 protrudes from the insertion portion 321. A first elastic member 311 is sleeved on the insertion portion 321, and one end of the first elastic member 311 abuts against the stop portion 322, while the other end of the first elastic member 311 abuts against the inner wall of the receiving cavity 21.

[0098] In the above embodiment, when the body 4 is in the unlocked state, the first elastic member 311 is in its natural state. When the push assembly 312 pushes the stop 322 to move and the insertion part 321 is inserted into the limiting structure 41, the first elastic member 311 is squeezed by the stop 322 and the inner wall of the receiving cavity 21, causing the first elastic member 311 to generate elastic force and apply it to the stop 322. When the body 4 is in the unlocked state, the first elastic member 311 returns to its natural state. During the process of the first elastic member 311 returning to its natural state, the elastic force generated by the first elastic member 311 pushes the stop 322 to drive the latch 32 to move as a whole until the insertion part 321 disengages from the limiting structure 41.

[0099] exist Figures 17 to 25 In the embodiment shown, when the body 4 is in the locked state, the first elastic element 311 is in the natural state, and when the body 4 is in the unlocked state, the first elastic element 311 is in the compressed state.

[0100] When the body 4 is in the unlocked state, the push assembly 312 moves the latch 32 to the disengagement limit structure 41, and the latch 32 presses against the first elastic member 311, and the elastic force generated by the first elastic member 311 is also applied to the latch 32. When the body 4 is in the locked state, the first elastic member 311 returns to its natural state. During the process of the first elastic member 311 returning to its natural state, the elastic force generated by the first elastic member 311 can move the latch 32 to the insertion limit structure 41.

[0101] Please refer to Figures 17 to 25 In some embodiments, the adapter 2 has a first chamber 23, a second chamber 24, a second through hole 25 communicating with the first chamber 23, and a third through hole 26 communicating with the second chamber 24; the push assembly 312 includes a third drive member 3126, a third elastic member 3127, and a second connector 3128. The third drive member 3126 and the third elastic member 3127 are both housed in the second chamber 24, the locking tongue 32 and the first elastic member 311 are both housed in the first chamber 23, and the second connector 3128 is connected to the third drive member 3126 and the locking tongue 32 respectively. When the fuselage 4 is in a locked state (e.g. Figure 18 and Figure 19 As shown, Figure 21 and Figure 22As shown), the adapter 2 rotates relative to the chassis 1, causing a portion of the end of the third drive member 3126 passing through the third through hole 26 to abut against the limiting surface 11 on the chassis 1. A portion of the third drive member 3126 is housed in the second chamber 24. The first elastic member 311 pushes the locking tongue 32 through the second through hole 25 and inserts it into the limiting structure 41. When the body 4 is in the unlocked state (e.g., ...), Figures 22 to 25 As shown), the adapter 2 rotates relative to the chassis 1, causing the third drive member 3126 to move until it disengages from the limiting surface 11. The third elastic member 3127 pushes the third drive member 3126, causing the third drive member 3126 to drive the second connector 3128 and the locking tongue 32 to move, and causing the locking tongue 32 to move until it disengages from the limiting structure 41 and presses against the first elastic member 311.

[0102] In the above embodiment, the second connector 3128 is connected to the third drive member 3126 and the locking tongue 32 respectively, which can maintain the distance between the third drive member 3126 and the locking tongue 32, so that the third drive member 3126 and the locking tongue 32 can move together.

[0103] For example, when the fuselage 4 is in the unlocked state (initial state), the third elastic element 3127 is compressed and applies a first force to the third driving element 3126, causing the third driving element 3126 to move away from the limiting structure 41. Meanwhile, the first elastic element 311 is compressed and applies a second force to the locking tongue 32, causing the locking tongue 32 to move closer to the limiting structure 41. Since the second connecting element 3128 is connected to both the third driving element 3126 and the locking tongue 32, it can apply tension to both, preventing them from moving away from each other. The first force is greater than the second force, allowing the locking tongue 32 to move into the first chamber 23 under the tension of the second connecting element 3128 to disengage from the limiting structure 41. During the locking process, the adapter 2 rotates relative to the chassis 1, causing the third drive member 3126 to abut against the limiting surface 11 and move into the second chamber 24. The third drive member 3126 further compresses the third elastic member 3127 to increase the first force. The movement of the third drive member 3126 into the second chamber 24 reduces the pulling force exerted by the second connector 3128 on the latch 32, allowing the latch 32 to be inserted into the limiting structure 41 under the action of the first elastic member 311. The second force decreases until the first elastic member 311 returns to its natural state (the second force...). (zero); During the unlocking process, the adapter 2 rotates relative to the chassis 1, causing the third drive member 3126 to disengage from the limiting surface 11. Under the push of the first force applied by the third elastic member 3127, the third drive member 3126 protrudes out of the second chamber 24 and moves away from the limiting structure 41. The protrusion of the third drive member 3126 out of the second chamber 24 can increase the pulling force of the second connector 3128 on the locking tongue 32, so that the locking tongue 32 moves into the first chamber 23 under the pulling force of the second connector 3128 to disengage from the limiting structure 41, and the locking tongue 32 squeezes the first elastic member 311.

[0104] In some embodiments, the second connector 3128 includes a second pull cord, a locking tongue 32 and a third drive member 3126 are respectively connected to the second pull cord, and the distance between the locking tongue 32 and the third drive member 3126 is equal to the length of the second pull cord. During the reciprocating movement of the third drive member 3126 and the locking tongue 32, the position of the second pull cord changes, and the shape of the second pull cord can be changed so that the second pull cord can adapt to the structure at different positions.

[0105] Please refer to Figure 20 In some embodiments, the adapter 2 is further provided with a communicating chamber 28 communicating with the first chamber 23 and the second chamber 24, and the second connector 3128 is housed in the communicating chamber 28.

[0106] The connecting chamber 28 can restrict the structure of the second connector 3128 and prevent the second connector 3128 from interfering with the operation of the adapter 2 or other components in the chassis 1.
