Description

Technical Field

[0001] This utility model relates to the field of vehicle bodies, and in particular to a vehicle body component and a vehicle. Background Technology

[0002] Vehicle body limiters are usually located between the rear pillar of the vehicle body assembly and the rear panel of the vehicle body to support and connect the rear panel of the vehicle body. Due to manufacturing tolerances in the vehicle body assembly and vehicle body limiters, the lengths of the limiters on both sides may be inconsistent after assembly, resulting in uneven force distribution. Utility Model Content

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a vehicle body assembly. According to this invention, the vehicle body assembly moves the adjusting component relative to the fixed part, changing the contact position between the limiting component and the terminal, driving the limiter to move, thereby achieving the extension and retraction of the limiter. This balances the forces on the limiters on both sides of the vehicle body, improving the stability of the vehicle body assembly and thus enhancing vehicle safety.

[0004] This utility model also proposes a vehicle including the above-mentioned vehicle body assembly.

[0005] The vehicle body assembly according to this utility model includes a vehicle body, a lid, a limiter, a fixing part, and an adjusting component. The vehicle body has a first wall and a second wall. The lid is rotatably disposed on the edge of the vehicle body. The limiter and the fixing part are configured to be at least two sets correspondingly disposed on the first wall and the second wall. One end of the limiter is connected to one of the vehicle body and the lid, and the fixing part is connected to the other of the vehicle body and the lid. The adjusting component is disposed on at least one of the fixing parts, and the adjusting component is movable relative to the fixing part. The adjusting component is provided with a limiting component. One end of the limiter is provided with a terminal for cooperating with the adjusting component. The terminal is adapted to abut against the limiting component to limit the extreme position of the terminal. The adjusting component moves relative to the fixing part to adjust the extension and retraction of the limiter.

[0006] According to this utility model, the vehicle body assembly has an adjusting component mounted on at least one fixed part. The adjusting component is movable relative to the fixed part to control the extension and retraction of a limiter. Specifically, the adjusting component has a limiter, and one end of the limiter has a terminal. During assembly, the limiter can abut against the terminal to limit the terminal's extreme position. When it is necessary to adjust the length of the limiter, i.e., control its extension and retraction, the adjusting component can be moved to cause relative displacement or rotation between the adjusting component and the fixed part, changing the abutment position between the limiter and the terminal, thereby changing the terminal's position, for example, moving it away from or closer to the fixed part. After operation, the limiter will move, realizing the extension and retraction of the limiter. This enables the adjustment component to control the extension and retraction of the limiter. When the box assembly and the limiter assembly have inconsistent forces due to manufacturing tolerances, i.e., one limiter is in a taut state and the other is in a slack state, the position of the adjustment component corresponding to the limiter in the taut state can be adjusted to extend the length of that limiter, thereby balancing the forces on the two limiters. This ensures that the box cover remains horizontal when open, avoiding problems such as box cover tilting or abnormal noise caused by uneven force, and improving the stability and reliability of the box assembly.

[0007] According to one embodiment of the present invention, a mating hole is formed on the terminal, the adjusting member is received in the mating hole, and a protruding limiting member is formed on the outer peripheral wall of the adjusting member; the hole wall of the mating hole is adapted to abut against the limiting member.

[0008] According to one embodiment of the present invention, the adjusting member is rotatably disposed on the fixed part to rotate relative to the fixed part, and the adjusting member can selectively rotate in the circumferential direction to adjust the position of the limiting member.

[0009] According to one embodiment of the present invention, the adjusting component is sleeved on the outer periphery of the fixing part, and the limiting component is constructed as a protrusion protruding from the outer peripheral wall of the adjusting component.

[0010] According to one embodiment of the present invention, the limiting component is symmetrically disposed on the outer periphery of the adjusting component.

[0011] According to one embodiment of the present invention, the limiting component and the adjusting component are integrally configured as a cam.

[0012] According to one embodiment of the present invention, the fixing part is constructed as a column passing through the adjusting member.

[0013] According to one embodiment of the present invention, the vehicle body assembly further includes: a reset member, the reset member being sleeved on the outer periphery of the fixed part, one end of the reset member being connected to the fixed part, and the other end of the reset member being connected to the adjustment component.

[0014] According to one embodiment of the present invention, the reset member is constructed as a torsion spring sleeved on the outer periphery of the fixed part, and the torsion spring is used to drive the adjusting member to rotate toward the initial position.

[0015] The vehicle according to this utility model is briefly described below.

[0016] The vehicle according to this utility model includes the vehicle body assembly in the above embodiments. Since the vehicle according to this utility model is equipped with the vehicle in the above embodiments, the vehicle body assembly can change the relative position of the limiter and the fixing part by moving the adjustment component, thereby realizing the adjustment of the limiter, ensuring that the limiters on both sides of the vehicle body can be subjected to balanced force, improving the stability of the vehicle body assembly, and thus improving the stability and safety of the vehicle.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] Vehicle body limiters are usually located between the rear pillar of the vehicle body assembly and the rear panel of the vehicle body to support and connect the rear panel of the vehicle body. Due to manufacturing tolerances in the vehicle body assembly and vehicle body limiters, the lengths of the limiters on both sides may be inconsistent after assembly, resulting in uneven force distribution.

[0022] The following is for reference. Figures 1-3 This invention describes a vehicle body assembly according to an embodiment of the present invention.

[0023] The vehicle body assembly 1 according to this utility model includes a vehicle body 11, a cover 12, a limiter 13, a fixing part 14, and an adjusting component 15. The vehicle body 11 has a first wall 111 and a second wall 112. The cover 12 is rotatably disposed on the edge of the vehicle body 11. The limiter 13 and the fixing part 14 are configured to be at least two sets correspondingly disposed on the first wall 111 and the second wall 112. One end of the limiter 13 is connected to one of the vehicle body 11 and the cover 12, and the fixing part 14 is connected to the other of the vehicle body 11 and the cover 12. The adjusting component 15 is disposed on at least one of the fixing parts 14. The adjusting component 15 is movable relative to the fixing part 14, and a limiting component 151 is provided on the adjusting component 15. One end of the limiter 13 is provided with a terminal 131 for cooperating with the adjusting component 15. The terminal 131 is adapted to abut against the limiting component 151 to limit the extreme position of the terminal 131. The adjusting component 15 moves relative to the fixing part 14 to adjust the extension and retraction of the limiter 13.

[0024] The vehicle body assembly 1 according to this utility model includes a vehicle body 11 and a cover 12. The vehicle body 11 has a first wall 111 and a second wall 112 spaced apart from each other in the vehicle width direction. The cover 12 is rotatably disposed on the edge of the vehicle body 11 and can be selectively opened or closed to facilitate the storage and retrieval of goods. Each of the first wall 111 and the second wall 112 is provided with a limiter 13 and a fixing part 14 connected to each other. Specifically, one of the fixing part 14 and the limiter 13 can be disposed on the corresponding first wall 111 or second wall 112, and the other of the fixing part 14 and the limiter 13 is connected to the cover 12. In actual assembly, the choice can be made according to the requirements. For example, the fixing part 14 can be disposed on the first wall 111 or the second wall 112, or the limiter 13 can be disposed on the first wall 111 or the second wall 112. In this utility model, the fixing part 14 is preferably disposed on the first wall 111 and the second wall 112, one end of the limiter 13 is connected to the fixing part 14, and the other end of the limiter 13 is connected to the box cover 12.

[0025] In addition, the vehicle body assembly 1 is provided with an adjustment component 15, which is disposed on at least one fixed part 14 and can move relative to the fixed part 14 to control the extension and retraction of the limiter 13. Specifically, the adjustment component 15 is provided with a limit component 151, and one end of the limiter 13 is provided with a terminal 131. During assembly, the limit component 151 can abut against the terminal 131 to limit the extreme position of the terminal 131. When it is necessary to adjust the length of the limiter 13, that is, to control the extension and retraction of the limiter 13, the adjustment component 15 can be moved to cause relative displacement or relative rotation between the adjustment component 15 and the fixed part 14, thereby changing the abutment position between the limit component 151 and the terminal 131, and thus changing the position of the terminal 131, for example, moving it away from the fixed part 14. When the terminal 131 moves near the fixed part 14, it will drive the limiter 13 to move, realizing the extension and retraction of the limiter 13. This enables the adjustment component 15 to control the extension and retraction of the limiter 13. When the cover 12 is opened due to manufacturing tolerances, the two limiters 13 are subjected to inconsistent forces, i.e., one limiter 13 is in a taut state and the other limiter 13 is in a slack state. The length of the limiter 13 can be extended by adjusting the position of the adjustment component 15 corresponding to the limiter 13 in the taut state, thereby balancing the forces on the two limiters 13. This ensures that the cover 12 can remain horizontal when open, avoiding problems such as tilting or abnormal noise caused by uneven force, and improving the stability and reliability of the use of the vehicle body assembly 1.

[0026] It should be noted that in this utility model, the length of the limiter 13 can be understood as the distance between the position where the limiting part and the cover 12 are connected and the fixing part 14. The extension and retraction of the limiter 13 can be the extension and retraction of the limiter 13 itself, or it can be the movement of the limiter 13 relative to the fixing part 14. For example, the movement of the limiter 13 away from the fixing part 14 is the extension of the limiter 13, and the movement of the limiter 13 closer to the fixing part 14 is the shortening of the limiter 13.

[0027] The vehicle body assembly 1 of this utility model features an adjustable component 15 that is movable relative to the fixed part 14. The movement of the adjustable component 15 adjusts the extension and retraction of the limiter 13, achieving adjustable length of the limiter 13. When the lengths of the left and right limiters 13 are inconsistent, this adjustment function can be used to bring the left and right limiters 13 to a suitable length, effectively solving the problem of inconsistent left and right lengths after assembly caused by manufacturing tolerances. This ensures the accuracy and stability of the vehicle body assembly 1 assembly, enhances the adaptability of the vehicle body assembly 1 to different manufacturing tolerances, and reduces assembly difficulties and subsequent failure rates caused by tolerance issues. In practical applications, users can flexibly adjust the position of the adjustable component 15 according to the actual usage of the vehicle body assembly 1 to achieve optimal limiting effect and force balance. The structure is simple, the operation is convenient, and adjustments can be completed without complex tools or professional knowledge, greatly improving the user experience.

[0028] According to one embodiment of the present invention, a mating hole 132 is formed on the terminal 131, the adjusting member 15 is received in the mating hole 132, and a protruding limiting member 151 is formed on the outer peripheral wall of the adjusting member 15; the hole wall of the mating hole 132 is adapted to abut against the limiting member 151.

[0029] A mating hole 132 is provided on the terminal 131, and the adjusting component 15 is received in the mating hole 132, so that the relative position between the terminal 131 and the adjusting component 15 is more precise and fixed. The wall of the mating hole 132 abuts against the protruding limiting component 151 on the outer peripheral wall of the adjusting component 15, forming a stable mechanical connection and limiting relationship. During the assembly and use of the car body assembly 1, it can effectively prevent unnecessary shaking or displacement of the limiter 13, greatly improve the overall assembly stability of the car body assembly 1, and ensure that the limiter 13 can accurately play its supporting and connecting role.

[0030] When the adjusting component 15 is received within the mating hole 132 of the terminal 131, a protruding limiting component 151 is formed on the outer peripheral wall of the adjusting component 15, and the hole wall of the mating hole 132 is adapted to abut against the limiting component 151. Therefore, during the movement (including translation, rotation, etc.) of the adjusting component 15 relative to the fixed part 14, the limiting component 151 will slide along at least a portion of the hole wall of the mating hole 132, thereby ensuring the stability and directionality of the adjusting component 15 during movement. When it is necessary to adjust the length of the limiter 13, simply move the adjusting component 15 to slide within the mating hole 132 to change the abutment position between the limiting component 151 and the terminal 131, thereby realizing the adjustment of the length of the limiter 13. This is convenient and quick, greatly improving the practicality and maintainability of the vehicle body assembly 1.

[0031] According to one embodiment of the present invention, the adjusting component 15 is rotatably disposed on the fixed part 14 and rotates relative to the fixed part 14. The adjusting component 15 can selectively rotate in the circumferential direction to adjust the position of the limiting component 151. By rotatably disposing the adjusting component 15 on the fixed part 14, the adjusting component 15 can rotate circumferentially around the fixed part 14. In practical applications, the user can change the position of the limiting component 151 by rotating the adjusting component 15 according to the specific situation of the vehicle body assembly 1, thereby achieving precise adjustment of the length of the limiter 13. For example, when it is found that the limiter 13 on one side is too long or too short, simply rotate the corresponding adjusting component 15 to move the limiting component 151 to the appropriate position, so that the limiter 13 reaches the required length, and the limiters 13 on both sides of the vehicle body 11 are balanced by force, ensuring the stability and reliability of the vehicle body assembly 1.

[0032] Furthermore, the rotatable design of the adjusting component 15 relative to the fixed part 14 makes the adjustment process of the adjusting component 15 more intuitive and convenient. Users do not need complicated operations or professional knowledge; they can easily complete the adjustment of the limiter 13 simply by rotating it, greatly improving the user experience. At the same time, the rotatable connection between the adjusting component 15 and the fixed part 14 also makes the structure of the entire carriage assembly 1 more compact and stable, effectively preventing problems such as loosening or displacement of the adjusting component 15 due to vibration or external forces, further improving the service life and safety of the carriage assembly 1.

[0033] According to one embodiment of the present invention, the adjusting component 15 is sleeved on the outer periphery of the fixing part 14, and the limiting component 151 is constructed as a protrusion protruding from the outer peripheral wall of the adjusting component 15. Sleeving the adjusting component 15 on the outer periphery of the fixing part 14 not only makes the connection between the adjusting component 15 and the fixing part 14 more stable, allowing the adjusting component 15 to rotate around the fixing part 14 as a base point with more stable rotation, but also facilitates the installation and disassembly of the adjusting component 15, and the overall structure is more compact, occupying less space and facilitating arrangement. The limiting component 151, constructed as a protrusion protruding from the outer peripheral wall of the adjusting component 15, has a simple and effective structure, enabling it to accurately abut against the inner peripheral wall of the mating hole 132 when the adjusting component 15 rotates or moves, thereby achieving precise control of the length of the limiter 13.

[0034] In practical applications, when it is necessary to adjust the length of the limiter 13, the user only needs to rotate or move the adjusting component 15 to make the limiting component 151 protruding from the outer peripheral wall of the adjusting component 15 and the terminal 131 relatively displaced, changing the contact position between the limiter 13 and the terminal 131, thereby moving the limiter 13 as a whole toward the direction away from or toward the fixed part 14, thereby realizing the adjustment of the length of the limiter 13 and ensuring that the limiters 13 on both sides of the carriage 11 are evenly stressed. This adjustment method is convenient and quick, without the need for complicated tools or professional knowledge, greatly improving the user's ease of use.

[0035] The adjusting component 15 is fitted around the outer periphery of the fixing part 14, making full use of the space of the fixing part 14. This allows the vehicle body assembly 1 to maintain a compact structure while also enabling flexible adjustment of the length of the limiter 13. This not only improves the practicality and maintainability of the vehicle body assembly 1, but also reduces the manufacturing and maintenance costs of the vehicle body assembly 1, bringing tangible economic benefits to vehicle manufacturers and users.

[0036] According to one embodiment of this utility model, the limiting components 151 are symmetrically arranged on the outer periphery of the adjusting component 15. After the vehicle body assembly 1 is assembled, when subjected to external force, the limiting components 151 can evenly distribute the force in all directions. For example, when the vehicle encounters bumps or turns during driving, the vehicle body 11 will generate forces in different directions. The symmetrically distributed limiting components 151 can avoid local stress concentration caused by uneven force, thereby effectively preventing the adjusting component 15 or the limiting components 151 themselves from deforming or being damaged due to excessive force, thus improving the stability and reliability of the limiting function. Due to the symmetrical arrangement of the limiting components 151, the contact and collision between each limiting component 151 and the mating component will be more uniform and coordinated during the movement of the vehicle body 11 with the vehicle. When the vehicle starts, stops, or changes its direction of movement, the symmetrical limiting structure can effectively buffer and absorb vibration and impact energy, making the vehicle body 11 move more smoothly with the vehicle. For example, during emergency braking of the vehicle, the symmetrical limiting components 151 can evenly reduce the forward momentum of the carriage 11, preventing the carriage 11 from shaking or jumping violently, and improving the stability of the carriage assembly 1.

[0037] Furthermore, the symmetrically arranged limiting components 151 ensure that a uniform force is applied to the limiter 13 when the adjusting component 15 rotates or moves. For example, when the user rotates the adjusting component 15 to change the contact position between the limiting component 151 and the terminal 131, the symmetrical limiting components 151 can act on the terminal 131 simultaneously, keeping the limiter 13 stable during extension and retraction, preventing jamming or abnormal extension and retraction caused by excessive force on one side, thereby improving the accuracy and effectiveness of the length adjustment of the limiter 13.

[0038] According to one embodiment of this utility model, the limiting component 151 and the adjusting component 15 are integrally arranged and constructed as a cam. Designing the limiting component 151 and the adjusting component 15 as an integral unit and constructing them as a cam fully utilizes the characteristics of the cam structure. As a common mechanical transmission element, the cam has advantages such as simple structure and flexible and controllable motion law. Moreover, the cam structure has a certain degree of adjustability; by changing the rotation angle or position of the cam, the working position and limiting range of the limiting component 151 can be adjusted, enabling the vehicle body assembly 1 to adapt to different working scenarios and loading requirements, thus improving the versatility and flexibility of the vehicle body assembly 1. In the vehicle body assembly 1, the integrated cam-type limiting component 151 can precisely change its contact position with the terminal 131 as the adjusting component 15 rotates or moves. In actual operation, when it is necessary to adjust the length of the limiter 13, the user only needs to rotate or move the adjusting component 15. The cam-type limiting component 151 will abut against the inner wall of the mating hole 132 on the terminal 131 with its specific contour curve, making the adjustment of the length of the limiter 13 more precise and delicate, and able to meet the precise requirements of the length of the limiter 13 under different working conditions.

[0039] The integrated design enhances the connection strength between the limiting component 151 and the adjusting component 15, reducing stress concentration. During long-term use, the carriage assembly 1 continuously endures alternating loads, which can easily lead to the generation and propagation of fatigue cracks. The integrated cam-type limiting component 151 and adjusting component 15, due to their structural continuity, effectively disperse stress, reducing the likelihood of fatigue cracks and thus extending the service life of the carriage assembly 1, improving its reliability and safety. Simultaneously, the cam-type structure makes it easier to ensure the precision of the limiting component 151 during manufacturing, reducing manufacturing costs and facilitating large-scale production applications. This integrated cam-type limiting component 151 design provides an efficient, reliable, and economical solution for adjusting the limiter 13 of the carriage assembly 1.

[0040] According to one embodiment of the present invention, the fixing part 14 is constructed as a column passing through the adjusting member 15. Constructing the fixing part 14 as a column (e.g., a stud) passing through the adjusting member 15 provides a stable and reliable support structure for the entire vehicle body assembly 1. The column-shaped fixing part 14 has high strength and rigidity, capable of withstanding various forces generated during the assembly and use of the vehicle body assembly 1, ensuring that the fixing part 14 itself will not deform or be damaged when the adjusting member 15 moves or rotates relative to the fixing part 14, thereby guaranteeing the stability and accuracy of the limiter 13's adjustment function. The column design of the adjusting member 15 allows the adjusting member 15, fitted around the fixing part 14, to rotate flexibly around the column, simplifying the connection between the adjusting member 15 and the fixing part 14 and improving the smoothness of the adjustment process. In practical applications, users can easily rotate or move the adjusting member 15 to quickly adjust the length of the limiter 13 without worrying about loosening or jamming between the adjusting member 15 and the fixing part 14.

[0041] Furthermore, the column-shaped fixing part 14 also possesses good versatility and interchangeability. During the production of the carriage assembly 1, the standardized column fixing part 14 can be used in conjunction with adjustment parts 15 of different specifications and models, thereby reducing production costs and inventory pressure. Simultaneously, when the carriage assembly 1 is damaged or requires upgrading, users can easily replace the fixing part 14 or the adjustment part 15, improving the maintainability and upgradeability of the carriage assembly 1.

[0042] The column-shaped fixing part 14 also provides more flexibility in the overall layout of the carriage assembly 1. Since the column occupies little space and can easily pass through the adjusting part 15, the fixing part 14 and the adjusting part 15 can be reasonably arranged within the limited space of the carriage assembly 1, making the structure of the carriage assembly 1 more compact and optimized. This not only improves the space utilization of the carriage assembly 1, but also reduces vibration and noise problems caused by loose structure, further improving the performance and comfort of the carriage assembly 1.

[0043] According to one embodiment of this utility model, the vehicle body assembly 1 further includes a reset member, which is sleeved on the outer periphery of the fixing part 14, with one end of the reset member connected to the fixing part 14 and the other end connected to the adjusting part 15. The reset member adds a convenient automatic return function to the adjustment process of the limiter 13 of the vehicle body assembly 1. After the user operates the adjusting part 15 to change the length of the limiter 13, the reset member, by virtue of its own elastic properties, can automatically return the adjusting part 15 to its initial position or a preset position at an appropriate time (such as when the user releases the adjusting part 15 or when the vehicle body assembly 1 is subjected to a specific external force), thereby improving the convenience and automation of the vehicle body assembly 1. Specifically, when the vehicle body assembly 1 is in normal use, and the adjusting part 15 moves due to external force, causing a change in the length of the limiter 13, the reset member will elastically deform accordingly. Once the external force disappears or the reset condition is met, the reset member will release its stored elastic potential energy, pushing the adjusting part 15 to move in the opposite direction until it returns to its original state or a specific position. For example, when the vehicle encounters bumps during operation, causing the adjustment component 15 of the vehicle body assembly 1 to move unexpectedly, the reset component can quickly function to reset the adjustment component 15, ensuring that the length of the limiter 13 is restored to the appropriate value, thereby maintaining the stability and reliability of the vehicle body assembly 1.

[0044] The reset component is sleeved on the outer periphery of the fixing part 14, with one end connected to the fixing part 14 and the other end connected to the adjusting component 15, so that the reset component can effectively transmit the elastic force to the adjusting component 15. Moreover, since the connection between the reset component and the fixing part 14 and the adjusting component 15 is tight and stable, it will not loosen or fall off due to frequent elastic deformation during long-term use, thus ensuring the durability and reliability of the reset function.

[0045] Furthermore, the reset component can also buffer and absorb the vibration and impact energy generated by the vehicle body assembly 1 during vehicle movement to a certain extent, reducing the direct effect of this energy on the adjusting component 15 and the limiter 13, thereby reducing wear and fatigue damage to the components and extending the service life of the vehicle body assembly 1. At the same time, the automatic return function of the reset component also allows the vehicle body assembly 1 to quickly return to its standard state after each use, preparing it for the next use and improving the efficiency and performance stability of the vehicle body assembly 1.

[0046] According to one embodiment of this utility model, the reset member is constructed as a torsion spring sleeved on the outer periphery of the fixed part 14. The torsion spring is used to drive the adjusting member 15 to rotate toward the initial position. By constructing the reset member as a torsion spring sleeved on the outer periphery of the fixed part 14, the torsion spring, after undergoing torsional deformation under external force, generates a torque to restore its original shape based on its internal elastic stress, thereby driving the adjusting member 15 to rotate toward the initial position. In practical applications, when the user operates the adjusting member 15 to rotate or move it to change the length of the limiter 13, the torsion spring will undergo torsional deformation and store elastic potential energy. Once the user releases the adjusting member 15 or the external force on the carriage assembly 1 changes, the torsion spring will release the stored elastic potential energy, generating a torque opposite to the rotation direction of the adjusting member 15, pushing the adjusting member 15 to rotate in the opposite direction until it returns to the initial position. This automatic return function greatly improves the convenience of using the carriage assembly 1, eliminating the need for the user to manually reset the adjusting member 15, saving operation time and effort.

[0047] The torsion spring is sleeved around the outer periphery of the fixing part 14, and the connection between the torsion spring and the fixing part 14 and the adjusting part 15 is tight and reliable. During long-term use, the torsion spring can maintain stable elastic performance and will not suffer from elastic decay or breakage due to frequent torsional deformation, thus ensuring the durability and reliability of the reset function. Moreover, the torsion spring has a relatively simple structure and low manufacturing cost, which is conducive to large-scale production and application, reducing the overall cost of the vehicle body assembly 1.

[0048] Furthermore, the torsion spring also acts as a buffer and shock absorber during the process of returning the adjusting component 15 to its original position. When the carriage assembly 1 is subjected to external impact or vibration, the torsion spring can absorb some of the energy through its elastic deformation, reducing the direct impact of this energy on the adjusting component 15 and the limiter 13, thereby reducing wear and fatigue damage to the components and extending the service life of the carriage assembly 1. At the same time, the automatic return function of the torsion spring also allows the carriage assembly 1 to quickly return to its standard state after each use, ensuring the accurate length of the limiter 13 and providing a reliable guarantee for the next use, thus improving the efficiency and performance stability of the carriage assembly 1.

[0049] The vehicle according to this utility model is briefly described below.

[0050] The vehicle according to this utility model includes the vehicle body assembly 1 in the above embodiments. Since the vehicle according to this utility model is equipped with the vehicle in the above embodiments, the vehicle body assembly 1 can change the relative position of the limiter 13 and the fixing part 14 by moving the adjusting component 15, thereby realizing the adjustment of the limiter 13, ensuring that the limiters 13 on both sides of the vehicle body 11 can be subjected to balanced force, improving the stability of the vehicle body assembly 1, and thus improving the stability and safety of the vehicle.
