Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an auxiliary vehicle loading and shifting device. Background Technology

[0002] In today's society, the daily travel needs of people with mobility impairments are becoming increasingly prominent. Cars, with their advantages of high mobility and convenient parking, have become one of the means of transportation for this group. However, people with mobility impairments have unique physical characteristics, generally experiencing muscle weakness and decreased balance. These characteristics make ensuring their safety when getting in and out of vehicles a critical requirement.

[0003] In related technologies, the protection for people with mobility impairments getting on and off vehicles is usually improved in the seat body, which typically includes a rotating mechanism and a moving mechanism. The rotating mechanism rotates the seat body towards the outside of the door through a vertical rotation axis, and the moving mechanism moves the seat body laterally to the outside of the vehicle through a transverse guide rail. By rotating the seat body towards the outside of the door and moving it laterally, the distance for getting on and off the vehicle is shortened, which significantly facilitates people with mobility impairments getting on and off the vehicle. The rotating mechanism uses a torque transmission system of drive motor, gearbox and transmission rod to ensure steering stability, and the moving mechanism achieves smooth displacement through a double guide rail assembly and lead screw transmission.

[0004] However, the above process requires the simultaneous coordination of the rotating mechanism and the moving mechanism. Since the rotating mechanism includes a drive motor, gearbox, and transmission rod, and the moving mechanism includes a double guide rail assembly and a lead screw, the structure is highly complex and requires a lot of space under the seat body and around the vehicle. Due to the limited interior space of some compact cars, it is difficult to apply this technology to compact cars. Utility Model Content

[0005] To address the aforementioned problems, this application provides an auxiliary vehicle shifter.

[0006] The auxiliary vehicle shifter provided in this application adopts the following technical solution:

[0007] An auxiliary vehicle transfer device, installed inside a vehicle, includes a support base and a base frame. The base frame is fixed between the seat body and the door. A flipping assembly is provided between the support base and the base frame. The flipping assembly is rotatably connected to the base frame. The flipping assembly is located at one end of the base frame and flips along the axis of the connection between the flipping assembly and the base frame. The support base is rotatably connected to the flipping assembly and rotates along the connection between the support base and the flipping assembly.

[0008] By adopting the above technical solution, when the shifter is idle, because the base frame is fixed between the seat body and the door, and because the flipping component is rotatably connected to the base frame, the flipping component can be flipped to a vertical state, further driving the carrier seat to flip to a vertical state. Furthermore, the carrier seat is rotatably connected to the flipping component, allowing it to rotate to a state parallel to the base frame in the vertical direction, and be stored in the gap between the seat body and the vehicle body, occupying less interior space and adapting to the cramped interior layout of compact cars. When assisting people with mobility issues to get in and out of the vehicle, the flipping component first moves along the axis of the connection between the flipping component and the base frame... The direction of the front of the vehicle is flipped, which simultaneously drives the carrier seat to flip forward to the door position and expose it. Then, the carrier seat flips outward along the connection between the carrier seat and the flipping component, making the carrier seat horizontal. This creates a smooth transition support surface for people with mobility impairments from the seat body to the door, allowing them to move safely along the horizontal carrier seat. At the same time, the overall structure is simple and low in complexity, which reduces production and maintenance costs. Due to its simple structure and small space occupation, it can stably adapt to the space constraints of compact cars, fully meeting the safety and convenience needs of people with mobility impairments to get in and out of compact cars.

[0009] Preferably, the flipping assembly includes a flipping seat, which is rotatably connected to the base frame, and the flipping seat flips along the horizontal axis at the connection between the flipping seat and the base frame.

[0010] By adopting the above technical solution, when not in use, the flip seat can remain vertical along with the carrier seat. It is fixed to the installation position between the seat body and the door by the base frame, and the carrier seat is stored in the gap between the seat body and the car body. It adapts to the space layout constraints of compact cars. When it is necessary to assist people with mobility difficulties to get in and out of the car, the flip seat can flip forward stably towards the front of the car, and at the same time drive the associated carrier seat to flip forward to be exposed to the door position. Moreover, the core action of the entire flip structure is achieved only by the rotation of the flip seat and the base frame. This simplifies the overall structure, reduces complexity and cost, and can accurately meet the needs of people with mobility difficulties to move safely, fully adapting to the usage scenarios of compact cars.

[0011] Preferably, the flipping assembly further includes a rotating shaft, one end of which is fixedly connected to the support base, and the other end of which is rotatably connected to the flipping base.

[0012] By adopting the above technical solution, the fixed connection between the support seat and the rotating shaft ensures that when the user rotates the support seat, the force can be directly transmitted to the rotating shaft. The rotational connection between the rotating shaft and the flip seat provides flexible movement space for this transmission, allowing the support seat to rotate smoothly around the rotating shaft. Whether adjusting from a vertical storage state to a horizontal use state or reversing to reset, it can maintain a stable trajectory. When a transitional support surface for assisting getting in and out of the vehicle needs to be built, the user can rotate the support seat to drive the rotating shaft to rotate smoothly within the flip seat, flipping the support seat from a vertical storage state to a horizontal use state. This ensures that the support seat can be stably positioned to accommodate human movement, providing smooth support for the user to move from the seat body to the outside of the car door. At the same time, this structure of fixed connection and rotational cooperation reduces the complexity of setup and production and maintenance costs, and also reduces the space occupied by components in the vehicle, adapting to the narrow interior layout of compact cars.

[0013] Preferably, the flipping assembly further includes a limiting block, which is sleeved on the end of the rotating shaft away from the support seat. The bottom of the flipping seat is provided with a limiting groove, which matches the outer contour of the limiting block.

[0014] By adopting the above technical solution, when the shifter is needed, pressing the support seat causes the limiting block, which is sleeved on the end of the rotating shaft away from the support seat, to disengage from the limiting groove at the bottom of the flip seat. At this time, the constraint between the limiting block and the limiting groove is released, the rotating shaft can rotate freely, and the support seat can smoothly flip around the rotating shaft to a horizontal state suitable for getting on and off the vehicle. This provides a smooth transition support surface for people with mobility difficulties from the seat body to the outside of the door. After the shifter is used, pressing the support seat again and rotating it causes the support seat to rotate and be stored away. When the pressure on the support seat is stopped, the limiting block can be inserted into the limiting groove to ensure the support seat remains stably in the retracted state. The insertion and engagement of the limiting block and the limiting groove prevents the support seat from rotating unexpectedly due to vehicle vibration or accidental contact. At the same time, the vertically retracted support seat is located in the gap between the seat body and the vehicle body. The limiting block and the limiting groove achieve their functions through simple socketing and insertion, reducing the complexity of the setup and production and maintenance costs, while also making it easy to control the switching between the rotation and limiting states of the support seat.

[0015] Preferably, the surface of the rotating shaft is provided with an elastic element, one end of which abuts against the bearing seat, and the other end of which abuts against the flip seat.

[0016] By adopting the above technical solution, when the shifter is needed, the carrier seat is pressed. During this process, the elastic element undergoes elastic deformation and stores elastic potential energy as the carrier seat is pressed. When the carrier seat rotates to the predetermined angle for assisting with getting on and off the vehicle, the pressing of the carrier seat is stopped, allowing the elastic element to release its potential energy and complete the reset. The abutting forces at both ends with the carrier seat and the flipping seat respectively form a stable support. This support force can effectively limit the carrier seat from being subjected to external forces, reduce the situation where the rotating shaft slides down along the flipping seat, and thus reduce the situation where the carrier seat accidentally flips due to sliding down. This ensures that the carrier seat is always stably maintained in the predetermined position, providing reliable support for people with mobility difficulties to move safely along the carrier seat.

[0017] Preferably, a fixing block is provided at the bottom of the support base, and a clearance groove is provided on the lower surface of the fixing block.

[0018] By adopting the above technical solution, when the shifter is used, the carrier seat flips to a horizontal position suitable for getting on and off the vehicle. The clearance groove on the lower surface of the fixing block can form a plug-in fit with the base frame, realizing the rapid positioning of the carrier seat and the base frame. At the same time, with the constraint effect after plugging in, the swaying and displacement of the carrier seat in the horizontal direction, as well as the risk of tilting caused by external forces, are effectively limited, ensuring that the carrier seat always maintains a stable horizontal support posture. This structure can achieve a stable effect simply by plugging in the clearance groove with the base frame. It is suitable for the space and cost requirements of compact cars, and can also provide a reliable support foundation for people with mobility difficulties to move from the seat body to the outside of the door along the carrier seat, reducing safety hazards caused by the instability of the carrier seat.

[0019] Preferably, the base frame is provided with a limiting member, and the flipping seat rotates to a vertical state and abuts against the limiting member.

[0020] By adopting the above technical solution, when the shifter is finished and the carrier needs to be reset to the vertical storage state, the flip seat will drive the carrier to rotate synchronously towards the gap between the seat body and the vehicle body. When the flip seat rotates to a predetermined angle close to the vertical storage, it will abut against the limiting component on the base frame, restricting the flip seat from continuing to rotate. This effectively reduces the situation where the carrier seat over-flips due to inertia or external force, ensuring that the flip seat can drive the carrier seat to stay in the vertical storage position. At the same time, the limiting component achieves the limiting function through simple mechanical abutment, which is suitable for the space requirements of compact cars, reduces the collision damage between the carrier seat and the vehicle interior components caused by over-flipping, and ensures that the vertically stored carrier seat is stably in the gap.

[0021] Preferably, the edge of the support seat is rounded.

[0022] By adopting the above technical solution, when people with mobility impairments move from the seat body to the door outside along the support seat, their bodies are likely to come into contact with the edge of the support seat. The rounded transition design can avoid the harsh friction or bumps caused by right-angled edges, and reduce the local pressure on the skin. In compact cars with limited interior space, the edge of the support seat is likely to come into contact with vehicle parts such as door trim and the side of the seat body during storage or use. The rounded transition design can reduce the deformation or wear of the support seat edge due to collisions.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When not in use, the base frame is fixed between the seat body and the door. The flipping component can be flipped to a vertical position and drive the carrier seat to flip synchronously. The rotating connection between the carrier seat and the flipping component allows the carrier seat to rotate to be vertical and parallel to the base frame, and finally stored in the gap between the seat body and the car body, greatly reducing the space occupied in the car and adapting to the narrow layout of compact cars. When in use, the flipping component first flips towards the front of the car along the axis of the connection with the base frame, driving the carrier seat forward to the door position and fully exposed. Then the carrier seat flips outward towards the door along the connection with the flipping component to a horizontal position, providing a smooth transition support surface for people with mobility difficulties from the seat to the outside of the door, ensuring safe movement. At the same time, the overall structure is simple and low in complexity, which reduces production and maintenance costs. The compact and stable structure is adapted to the space limitations of compact cars, fully meeting the safety and convenience needs of people with mobility difficulties to get on and off the car.

[0025] 2. When in use, pressing the support seat will disengage the limiting block from the limiting groove, releasing the fit constraint and allowing the rotating shaft to smoothly rotate the support seat to a horizontal state, providing a stable transition support surface for people with mobility difficulties. When storing, press and rotate the support seat to the stored state again. After releasing, the limiting block and the limiting groove will form an interlocking fit, which can effectively limit the support seat from accidental rotation due to vehicle vibration or accidental touch, keeping the support seat stably in a vertical stored state and located in the gap between the seat and the body. At the same time, the above structure reduces the design complexity and production and maintenance costs, and can control the state switching of the support seat, adapting to the space and usage requirements of compact cars.

[0026] 3. When the shifter is used, during the pressing of the carrier seat, the elastic element undergoes elastic deformation and stores elastic potential energy. After the carrier seat rotates to the predetermined angle for assisting in getting on and off the vehicle, the pressing stops, and the elastic element releases its potential energy to complete the reset. Stable support is formed by the contact force between the two ends and the carrier seat and the flipping seat respectively. This support force can effectively limit the carrier seat from sliding down the rotating axis along the flipping seat due to external forces, thereby reducing the possibility of the carrier seat accidentally flipping due to sliding down. This ensures that the carrier seat is always stably maintained in the predetermined position, providing reliable support for people with mobility difficulties to move safely along the carrier seat. At the same time, it continues the design features of the shifter, which is simple in structure and adaptable to compact trolleys. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses an auxiliary vehicle transfer device. (Refer to...) Figure 1An auxiliary vehicle transfer device is installed inside a vehicle and includes a support seat 1 and a base frame 2. The base frame 2 is fixed between the seat body and the door. A flipping component 3 is provided between the support seat 1 and the base frame 2. The flipping component 3 is rotatably connected to the base frame 2 and is located at one end of the base frame 2. The flipping component 3 flips along the axis of the connection between the flipping component 3 and the base frame 2. The support seat 1 is rotatably connected to the flipping component 3 and rotates along the axis of the connection between the support seat 1 and the flipping component 3.

[0036] This explains that when the shifter is idle, since the base frame 2 is fixed between the seat body and the door, and the flip assembly 3 is rotatably connected to the base frame 2, the flip assembly 3 can be flipped to a vertical state, which further drives the carrier seat 1 to be flipped to a vertical state. The carrier seat 1 is rotatably connected to the flip assembly 3, which allows the carrier seat 1 to be rotated to a state parallel to the base frame 2 in the vertical direction, and stored in the gap between the seat body and the vehicle body, occupying less interior space and adapting to the narrow interior layout of compact cars.

[0037] Furthermore, when assisting people with mobility impairments to get on and off the vehicle, the tilting component 3 first tilts towards the front of the vehicle along the axis connecting the tilting component 3 and the base frame 2, simultaneously tilting the support seat 1 forward to the door position and exposing it. Then, the support seat 1 tilts outward towards the door along the connection between the support seat 1 and the tilting component 3, making the support seat 1 horizontal. This provides a smooth transition support surface for people with mobility impairments from the seat body to the door, allowing them to move safely along the horizontal support seat 1. At the same time, the overall structure is simple and low in complexity, which reduces production and maintenance costs. Due to its simple structure and small footprint, it can stably adapt to the space limitations of compact cars, fully meeting the safety and convenience needs of people with mobility impairments to get on and off compact cars.

[0038] Reference Figure 3 and Figure 4 Specifically, the chassis 2 includes a first frame 21, a second frame 22, and a connecting seat 23. The first frame 21 is a cylindrical tubular structure, and the second frame 22 is a multi-segmented bent tubular structure. The second frame 22 is formed by multiple bends and has multiple bends at different angles. The bends are connected by smooth bends. One end of the connecting seat 23 is fixedly connected to the second frame 22 in the horizontal direction, and the lower end of the connecting seat 23 is fixedly connected to the first frame 21. The lower ends of both the first frame 21 and the second frame 22 are fixedly connected to the vehicle body.

[0039] Reference Figure 2Furthermore, the flipping component 3 is disposed at the upper end of the connecting seat 23. The flipping component 3 is rotatably connected to the connecting seat 23. The flipping component 3 includes a flipping seat 31, which is rotatably connected to the connecting seat 23. A shaft 32 is disposed between the flipping seat 31 and the connecting seat 23. The shaft 32 is rotatably connected to the connecting seat 23, and both ends of the flipping seat 31 are fixedly connected to the shaft 32. The flipping seat 31 can flip along the axis of the shaft 32. At the same time, the connecting seat 23 is provided with a limiting member 231. There are two limiting members 231. In this embodiment, the limiting member 231 is set as a limiting post, or the limiting member 231 can also be set as a screw.

[0040] Furthermore, the flipping assembly 3 also includes a rotating shaft 33. One end of the rotating shaft 33 is fixedly connected to the support 1, and the other end is rotatably connected to the flipping base 31. Specifically, the support 1 is provided with a insertion groove 11, and the rotating shaft 33 is provided with an insertion part 331. The outlines of both the insertion groove 11 and the insertion part 331 are rectangular. The edges of the four sides of the insertion groove 11 are rounded, and the four sides of the insertion part 331 are chamfered. The insertion part 331 engages with the insertion groove 11. Through the guiding effect of the rounded corners and chamfers, the insertion part 331 can be inserted into the insertion groove 11 more smoothly and conveniently, reducing the assembly difficulty and effectively limiting the relative rotation of the support 1 and the rotating shaft 33 in the circumferential direction.

[0041] Reference Figure 5 Furthermore, the flipping assembly 3 also includes a limiting block 34, which is provided with an insertion interface 341. The end of the rotating shaft 33 away from the insertion part 331 is provided with a limiting part 332. The insertion interface 341 is sleeved on the limiting part 332 and snapped in place. The bottom of the flipping seat 31 is provided with a limiting groove 311, which matches the outer contour of the limiting block 34. At the same time, the contours of the limiting part 332 and the insertion interface 341 are both rectangular. The edges of the four sides of the insertion interface 341 are rounded, and the four sides of the limiting part 332 are chamfered. The limiting part 332 and the insertion interface 341 are snapped in place.

[0042] Furthermore, an elastic element 35 is provided on the surface of the rotating shaft 33. The elastic element 35 is sleeved on the rotating shaft 33. One end of the elastic element 35 abuts against the bearing seat 1, and the other end abuts against the flip seat 31. In this embodiment, the elastic element 35 is set as a helical spring, which has good elasticity.

[0043] This explains that, in the idle state, since the first frame 21 and the connecting seat 23 are located between the seat body and the vehicle body, and the carrier seat 1 is rotatably connected to the connecting seat 23 through the flip seat 31, the flip seat 31 and the carrier seat 1 together maintain a vertical state and are stored in the gap between the seat body and the vehicle body. At this time, the flip seat 31 will abut against the limiting piece 231 on the base frame 2, restricting the flip seat 31 from continuing to rotate, effectively reducing the situation where the carrier seat 1 will over-flip due to inertia or external force, and ensuring that the flip seat 31 can drive the carrier seat 1 to stay in the vertical storage position.

[0044] Furthermore, when assisting a person with mobility impairment to get in and out of the vehicle, since the shaft 32 is rotatably connected within the connecting seat 23 and the flip seat 31 is fixedly connected to the shaft 32, the user first flips the flip seat 31 along the axis of the shaft 32 within the connecting seat 23 via the shaft 32, and the support seat 1 is rotatably connected to the flip seat 31 via the rotating shaft 33, further driving the support seat 1 to flip towards the front of the vehicle, so that the support seat 1 flips from the gap between the seat body and the vehicle body to the position where the support seat 1 is exposed to the door.

[0045] Furthermore, when the user presses the support seat 1, the limiting block 34 sleeved on the limiting part 332 disengages from the limiting groove 311 at the bottom of the flip seat 31. After the constraint is released, since the support seat 1 is fixedly connected to the rotating shaft 33, the user can flip the support seat 1 around the axis of the rotating shaft 33 toward the outside of the car door, so that the support seat 1 can be flipped to a horizontal use state, providing a smooth transition support for the user to move from the seat body to the outside of the car door.

[0046] Furthermore, during this process, since one end of the elastic element 35 abuts against the bearing seat 1 and the other end of the elastic element 35 abuts against the flip seat 31, the elastic element 35 undergoes elastic deformation and stores elastic potential energy as the bearing seat 1 is pressed. When the bearing seat 1 reaches the predetermined angle, the pressing of the bearing seat 1 is stopped, and the elastic element 35 releases its potential energy to reset the bearing seat 1. The limiting block 34 is built into the limiting groove 311. The abutment force between the elastic element 35, the flip seat 31, and the bearing seat 1 forms a stable support, effectively reducing the downward sliding of the rotating shaft 33 along the flip seat 31 caused by external force on the bearing seat 1.

[0047] Furthermore, when the limiting block 34 disengages from the limiting groove 311, the constraint between the limiting block 34 and the limiting groove 311 is released, and the rotating shaft 33 can rotate freely. The carrier seat 1 can then be flipped to a horizontal state suitable for getting on and off the vehicle. After the shifter is used, the carrier seat 1 is pressed again and rotated. When the carrier seat 1 is rotated until the limiting block 34 matches the contour position of the limiting groove 311 at the bottom of the flip seat 31, the limiting block 34 can form an insertion fit with the limiting groove 311, further ensuring that the carrier seat 1 is stably kept in a vertical state and reducing the risk of the carrier seat 1 rotating unexpectedly due to vehicle vibration or accidental contact.

[0048] Reference Figure 6 In addition, the support seat 1 is provided with a fixing block 12, and the fixing block 12 is provided with a clearance groove 121. When the support seat 1 is flipped to a horizontal position suitable for getting on and off the vehicle, part of the structure of the second base frame 2 is built into the clearance groove 121, realizing the quick positioning of the support seat 1 and the base frame 2. At the same time, with the constraint of the clearance groove 121 on the first base frame 2, the swaying and displacement of the support seat 1 in the horizontal direction and the risk of tilting caused by external forces are effectively limited, ensuring that the support seat 1 always maintains a stable horizontal support posture. This structure can achieve a stable effect simply by plugging the clearance groove 121 into the base frame 2, which is suitable for the space and cost requirements of compact cars, and can also provide a reliable support foundation for people with mobility difficulties to move from the seat body to the outside of the car door along the support seat 1, reducing the safety hazards caused by the instability of the support seat 1.

[0049] In addition, the edges of the support seat 1 are rounded. When people with mobility impairments move along the support seat 1 from the seat body to the door, their bodies are likely to come into contact with the edges of the support seat 1. The rounded transition can avoid the harsh friction or bumps caused by right-angled edges and reduce the local pressure on the skin. The interior space of compact cars is small. During storage or use, the edges of the support seat 1 are likely to come into contact with vehicle parts such as the door trim and the side of the seat body. The rounded transition can reduce the deformation or wear of the edges of the support seat 1 due to collisions.

[0050] The implementation principle of an auxiliary vehicle shifter according to an embodiment of this application is as follows:

[0051] First, the base frame 2 is used as the installation base. The base frame 2 consists of a cylindrical tubular first frame 21, a bent tubular second frame 22 with multiple smooth bends, and a connecting seat 23. The lower ends of the first frame 21 and the second frame 22 are fixed to the vehicle body. The horizontal end of the connecting seat 23 is connected to the second frame 22, and the lower end of the connecting seat 23 is connected to the first frame 21. The whole is fixed between the seat body and the door, providing stable installation support for the shifter, and adapting to the space layout of compact cars.

[0052] In the idle state, the flip assembly 3 and the connecting seat 23 are rotatably connected through the shaft 32. The flip seat 31 drives the carrier seat 1 to remain in a vertical state, and the carrier seat 1 is connected to the flip seat 31 through the rotating shaft 33. It can be rotated to be vertically parallel to the base frame 2 and finally stored together in the gap between the seat body and the vehicle body, reducing space occupation. At this time, the limiting part 332 of the rotating shaft 33 away from the insertion part 331 is locked with the limiting block 34. The limiting block 34 is inserted into the limiting groove 311. Combined with the pre-tightening force of the elastic element 35 sleeved on the surface of the rotating shaft 33, the carrier seat 1 and the flip seat 31 are respectively abutted, ensuring that the carrier seat 1 is stably stored.

[0053] In the assisted entry and exit mode, the operation consists of two steps: First, the user pushes the tilting seat 31 to tilt towards the front of the vehicle around the axis of the shaft 32, simultaneously tilting the support seat 1 from the gap to the door position. When the tilting seat 31 rotates to the predetermined angle, the support seat 1 is precisely exposed at the door. Second, the user presses the support seat 1, compressing the coil spring to create elastic deformation and store energy, simultaneously driving the rotating shaft 33 to move synchronously, causing the limiting block 34 to disengage from the limiting groove 311 and release its constraint. Then, the support seat 1 tilts outward around the axis of the rotating shaft 33 towards the door. When the support seat 1 is in a horizontal state, stop pressing. The elastic element 35 releases its potential energy to reset, causing the limiting block 34 to re-engage into the limiting groove 311. At the same time, the positioning groove 121 engages with the second frame 22. Under the dual action, the support seat 1 is restricted from sliding, swaying or shifting, ensuring that the support seat 1 maintains a stable horizontal support posture. This provides a smooth transition surface from the seat body to the outside of the car door for people with mobility impairments. In addition, the rounded edge design of the support seat 1 can reduce friction and bumps when the human body comes into contact with it, and also reduce collision damage with the interior parts of the vehicle.

[0054] In the retracted and reset state, the user presses the support seat 1 again, causing the limiting block 34 to disengage from the limiting groove 311, pushing the support seat 1 to rotate back to vertical around the rotating shaft 33, and then pushing the flip seat 31 to rotate back to the initial position around the shaft 32. The flip seat 31 abuts against the two limiting members 231 on the connecting seat 23, limiting the flip seat 31 from over-flipping. After releasing the support seat 1, the limiting block 34 and the limiting groove 311 are re-inserted, the elastic member 35 remains pre-tightened, and the flip seat 31 and the support seat 1 are retracted vertically into the gap, returning to the idle state, waiting for the next use.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
