Description

Technical Field

[0001] This application relates to the technical field of vehicle engineering, specifically to a vehicle body and a vehicle. Background Technology

[0002] In the prior art, the front compartment has a cabin body and a cover that opens and closes relative to the cabin body. When the cover and cabin body are in the closed state, a limiting part is provided on the cover to limit the opening and closing angle of the cover and cabin body. However, with this design, when the cover and cabin body are in the open state, the limiting part will also be exposed outside the cabin body as the cover flips over, which makes the limiting part easy to fall off and easy to be observed, affecting the perception quality. Therefore, a design is needed to hide the limiting part and reduce its risk of falling off. Utility Model Content

[0013] This application also provides a vehicle including the aforementioned body.

[0014] The vehicle body and vehicle proposed in this application have the following advantages: The body includes a cabin component and a hinge component. The cabin component includes a cabin and a cover that opens and closes relative to the cabin. The hinge component is located on the cabin and cover support, and achieves relative opening and closing of the cabin and cover through its own rotational structure. The hinge component includes a rotating arm, a linkage assembly, a fixed plate, and a first limiting part. The fixed plate includes a first plate and a second plate arranged at an angle. The rotating arm is connected to the cover. The linkage assembly is rotatably connected to the rotating arm and the first plate respectively. The second plate is connected to the cabin.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] In the prior art, the front compartment has a cabin body and a cover that opens and closes relative to the cabin body. When the cover and cabin body are in the closed state, a limiting part is provided on the cover to limit the opening and closing angle of the cover and cabin body. However, with this design, when the cover and cabin body are in the open state, the limiting part will also be exposed outside the cabin body as the cover flips over, which makes the limiting part easy to fall off and easy to be observed, affecting the perception quality. Therefore, a design is needed to hide the limiting part and reduce its risk of falling off.

[0027] To solve the above technical problems, refer to Figure 1 As shown, this application provides a vehicle body, including a cabin component 100 and a hinge component 200. The cabin component 100 includes a cabin 110 and a cover 120 that opens and closes relative to the cabin 110. The hinge component 200 is provided on a bracket 250 of the cabin 110 and the cover 120, and realizes the relative opening and closing of the cabin 110 and the cover 120 through its own rotation structure.

[0028] In some implementations, refer to Figure 1 and Figure 2 As shown, the hinge component 200 includes a rotating arm 210, a connecting rod assembly 220, a fixing plate 230, and a first limiting part 240. The fixing plate 230 includes a first plate 231 and a second plate 232 arranged at an angle. The rotating arm 210 is connected to the cover 120. The connecting rod assembly 220 is rotatably connected to the rotating arm 210 and the first plate 231 respectively. The second plate 232 is connected to the cabin 110. The first limiting part 240 is connected to the side of the second plate 232 facing the cover 120. The first limiting part 240 is configured to abut against the cover 120 when the cover 120 and the cabin 110 are in a closed state. The fixing plate 230 adopts a structure in which the first plate 231 and the second plate 232 are set at an angle, which can better adapt to the installation space between the cabin 110 and the cover 120, making the layout of the hinge component 200 more compact and reasonable. After the rotating arm 210 is connected to the cover 120, the cover 120 can be opened and closed smoothly through the rotational cooperation of the connecting rod assembly 220 and the first plate 231. The connection between the second plate 232 and the cabin 110 provides a stable support foundation for the entire hinge component 200. By setting the first limiting part 240 on the side of the second plate 232 facing the cover 120, when the cover 120 and the cabin 110 are in the closed state, the first limiting part 240 can directly abut against the cover 120 to achieve the limiting function. When the cover 120 is opened, since the first limiting part 240 is connected to the second plate 232 on the side of the cabin 110 and does not flip with the cover 120, the problem of the limiting structure being exposed outside the cabin 110 is effectively avoided, the risk of falling off is reduced, and the overall perception quality of the vehicle is improved.

[0029] In some implementations, refer to Figure 2As shown, the linkage assembly 220 includes a first link 221 and a second link 222. The first link 221 and the second link 222 are spaced apart on the first plate 231, and their sides are rotatably connected to the first plate 231 and the rotating arm 210, respectively. The first link 221 and the second link 222 of the linkage assembly 220 can improve the connection strength of the hinge component 200. The spaced first link 221 and the second link 222 can simultaneously support the cover 120 and the cabin 110 during the relative opening and closing process, thereby improving the support strength of the cabin component 100. The rotatable connection of the first link 221 and the second link 222 to the first plate 231 and the rotating arm 210, respectively, makes the movement trajectory of the cover 120 more stable during opening and closing, avoiding jamming or shaking. Specifically, when the cover 120 is opened relative to the cabin 110, the rotating arm 210 drives the first link 221 and the second link 222 to rotate around the connection point with the first plate 231, respectively. The synergistic effect of the two links can effectively disperse the weight of the cover 120 and the impact force during the movement, thereby extending the service life of the hinge component 200.

[0030] In some implementations, refer to Figure 2 and Figure 3 As shown, the hinge component 200 also includes a bracket 250, which is connected to the second plate 232 and extends toward the cover 120. The first limiting portion 240 is connected to the bracket 250. The bracket 250 provides a stable mounting base for the first limiting portion 240, increasing its stability during vehicle movement or frequent opening and closing of the cover 120. When the cover 120 is closed to a specific position, the first limiting portion 240 abuts against the cover 120, preventing the cover 120 from affecting the vehicle's sealing or operational safety due to over- or under-closure.

[0031] In some embodiments, a accommodating cavity is formed inside the housing 110 to accommodate at least one of a generator, engine, reducer, and various components. A fixing plate 230 is connected to the cavity wall and extends towards the cover 120. The cavity wall and the fixing plate 230 are fixedly connected by bolts or welding, reducing the risk of the fixing plate 230 loosening or falling off under long-term load and vibration conditions, thus providing reliable protection for the components inside the housing 110. Simultaneously, the first limiting part 240 may be configured as a buffer pad, flexible pad, etc., which can effectively absorb the collision force between the cover 120 and the fixing plate 230 when the cover 120 is closed, reducing noise generation and preventing wear caused by direct friction between metal parts.

[0032] In some implementations, refer to Figure 3As shown, the bracket 250 includes a connecting portion 251 and a mounting portion 252 arranged at an angle. The connecting portion 251 is connected to the second plate 232, and the mounting portion 252 extends toward the cover 120. A first limiting portion 240 is connected to the mounting portion 252. The connecting portion 251 and the second plate 232 can be fixedly connected by bolts or welding. The extension length of the mounting portion 252 can be adaptively adjusted according to the closing stroke of the cover 120 so that the first limiting portion 240 can abut against the cover 120 when the cover 120 is closed to a preset position. In addition, the angle between the connecting portion 251 and the mounting portion 252 can be designed to be different specifications such as 90 degrees and 120 degrees to adapt to the internal space layout of different vehicle body compartments 110, improving the versatility of the bracket 250. The first limiting portion 240 and the mounting portion 252 can be connected by threaded connection or adhesive coating process. Specifically, the mounting part 252 can have threads or grooves formed on the side facing the cover 120. The first limiting part 240 is fixed to the mounting part 252 by threaded connection or snap-fit. This design facilitates the replacement and maintenance of the first limiting part 240. When the first limiting part 240 ages or is damaged due to long-term use, it is not necessary to replace the entire bracket 250, effectively reducing maintenance costs. The first limiting part 240 and the mounting part 252 form a flexible structure on the outside of the mounting part 252 through a rubber coating process. This design can increase the structural stability of the mounting part 252 and the first limiting part 240 and prevent the first limiting part 240 from falling off during use. At the same time, in order to facilitate maintenance and replacement of the connecting part 251 and the second plate 232, a threaded connection can be used to achieve a fixed connection. When the first limiting part 240 is damaged, the bracket 250 can be disassembled to replace the bracket 250 and the first limiting part 240.

[0033] In some implementations, refer to Figure 2 As shown, the first limiting part 240 and the connecting rod assembly 220 are spaced apart in a direction that forms an angle with the first plate 231, and the distance between the first limiting part 240 and the connecting rod assembly 220 is between 0 and 0.5 mm; or, the first limiting part 240 and the connecting rod assembly 220 are interference-fitted in a direction that forms an angle with the first plate 231, and the interference distance between the first limiting part 240 and the connecting rod assembly 220 is between 0 and 0.5 mm.

[0034] In some specific implementations, refer to Figure 2As shown, the first limiting part 240 and the first connecting rod 221 are spaced apart in a direction forming an angle with the first plate 231, with the distance between the first limiting part 240 and the first connecting rod 221 being between 0 and 0.5 mm. During the frequent opening and closing of the cover 120 relative to the cabin 110, this design reduces friction between the first limiting part 240 and the first connecting rod 221. Since the first limiting part 240 is often made of flexible material, while the first connecting rod 221 is often made of metal, and the hardness of the first connecting rod 221 is much greater than that of the first limiting part 240, this design also increases the service life of the first limiting part 240. Specifically, the distance between the first limiting part 240 and the first connecting rod 221 can be set to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm, depending on the actual situation.

[0035] In another specific embodiment, refer to Figure 2 As shown, the first limiting part 240 and the first connecting rod 221 are interference-fitted in a direction forming an angle with the first plate 231, and the interference distance between the first limiting part 240 and the first connecting rod 221 is between 0 and 0.5 mm. During the closing process of the cover 120 relative to the cabin 110, the first connecting rod 221 is located between the second plate 232 and the first limiting part 240. The interference fit between the first limiting part 240 and the first connecting rod 221 allows them to abut against the first connecting rod 221. In the direction from the first plate 231 to the first limiting part 240, this prevents the first connecting rod 221 from shaking and reduces vehicle noise. Specifically, the interference distance between the first limiting part 240 and the first connecting rod 221 can be set to 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm, depending on the actual situation.

[0036] In some implementations, refer to Figure 2As shown, the first link 221 is located on the side of the first plate 231 away from the front of the vehicle body, and the middle of the first link 221 has a first blocking part 2211; the second plate 232 has a second blocking part 2321, and the first blocking part 2211 is configured to abut against the second blocking part 2321 when the cover 120 and the cabin 110 are closed. During vehicle operation, the front of the vehicle is the front of the vehicle, and the first link 221 is located on the side of the first plate 231 away from the front of the vehicle body, that is, the first link 221 is located on the side of the first plate 231 closer to the driver's cabin. When the cover 120 gradually approaches the cabin 110 and finally closes, as the rotating arm 210 rotates, the first link 221 will rotate around its connection point with the first plate 231. At this time, the first blocking part 2211 in the middle of the first link 221 will also move accordingly until it abuts against the second blocking part 2321 on the second plate 232. This abutting fit further enhances the limiting effect on the connecting rod assembly 220 when the cover 120 is closed, maintaining the relative position of the cover 120 and the cabin 110, preventing excessive movement of the cover 120, and increasing the tightness between the cover 120 and the cabin 110 after closure. The first blocking part 2211 and the second blocking part 2321 can be provided with flexible blocking parts. When the cover 120 and the cabin 110 are closed, the first blocking part 2211 and the second blocking part 2321 abut against each other, which can reduce engagement noise.

[0037] In some implementations, refer to Figure 2As shown, the rotating arm 210 and the first connecting rod 221 are rotatably configured to form a first rotating part 310, and the first plate 231 and the first connecting rod 221 are rotatably configured to form a second rotating part 320. The second rotating part 320 is located on the side closer to the front of the vehicle body relative to the first rotating part 310. The rotating arm 210 and the second connecting rod 222 are rotatably configured to form a third rotating part 330, and the first plate 231 and the second connecting rod 222 are rotatably configured to form a fourth rotating part 340. The fourth rotating part 340 is located on the side closer to the front of the vehicle body relative to the third rotating part 330. By arranging the first rotating part 310, the second rotating part 320, the third rotating part 330, and the fourth rotating part 340 in the above positional relationship, the force on the connecting rod assembly 220 is more balanced when the rotating arm 210 drives the cover 120 to open or close. When the cover 120 is opened, the second rotating part 320 and the fourth rotating part 340, located closer to the front of the vehicle body, can guide the rotation trajectory of the connecting rod earlier, while the first rotating part 310 and the third rotating part 330, located further away from the front, move in coordination. This layout effectively reduces motion interference between the rotating parts and improves the overall rotational smoothness of the hinge component 200. Simultaneously, the positional distribution of the rotating parts also creates a more reasonable lever arm structure at the connection point between the rotating arm 210 and the connecting rod assembly 220. This reduces the torque borne by a single rotating part when supporting the weight of the cover 120, thereby reducing wear on components and extending the service life of the hinge component 200. Furthermore, this structural design facilitates a compact layout of the hinge component 200 within the limited installation space of the compartment 110, avoiding spatial conflicts with other components inside the compartment 110 and improving the space utilization of the vehicle's front compartment.

[0038] In some implementations, refer to Figure 2As shown, the rotating arm 210 has a second limiting part 211 in the direction away from the head of the vehicle body from the first rotating part 310; when the cover 120 and the cabin 110 are in the open state, the second limiting part 211 in the circumferential direction of the first rotating part 310 is spaced apart from the first connecting rod 221; when the cover 120 and the cabin 110 are in the closed state, the second limiting part 211 in the circumferential direction of the first rotating part 310 abuts against the first connecting rod 221. This design allows the second limiting part 211 to abut against the first connecting rod 221 when the cover 120 is closed, forming a double limiting structure with the first blocking part 2211 and the second blocking part 2321, increasing the limiting fault tolerance space of the hinge assembly. That is, even if one limiting structure fails, the limiting function of the hinge assembly can still be maintained by the other limiting structure, reducing the risk that the hinge assembly will become unusable due to the failure of a single limiting structure. Furthermore, the rotating arm 210 includes a long arm portion connected to the cover 120. The long arm portion is located on the side of the first rotating part 310 near the head of the vehicle body. The length of the second limiting part 211 is less than the length of the long arm portion. During the opening and closing of the cover 120, the operating radius of the second limiting part 211 is much smaller than the operating radius of the long arm portion, thereby adapting to the spatial layout of the cabin 110. The second limiting part 211 is provided with a hook structure. When the cover 120 and the cabin 110 are closed, the second limiting part 211 hooks onto the second connecting rod 222 in the lateral direction of the vehicle, which can reduce the risk of the hinge assembly swaying in the lateral direction of the vehicle during vehicle use.

[0039] In some implementations, refer to Figure 2As shown, the fixing plate 230 also includes a third plate 233. The second plate 232 is connected to the third plate 233 on the side opposite to the first plate 231. The third plate 233 extends away from the first plate 231 and is connected to the cabin 110. The third plate 233 further enhances the stability of the connection between the fixing plate 230 and the cabin 110. By increasing the connection area with the cabin 110, the mounting base of the hinge component 200 on the cabin 110 is more secure. When the internal components of the cabin 110 vibrate during operation or when the vehicle encounters bumpy road conditions, the third plate 233 can distribute the stress borne by the fixing plate 230, preventing stress concentration from causing deformation or damage at the connection 251 between the second plate 232 and the cabin 110. Specifically, the third plate 233 can be fixed to the inner wall of the cabin 110 or a pre-set mounting bracket 250 by means of bolts, welding, or riveting. Its extension direction can be adjusted according to the internal spatial structure of the cabin 110, for example, extending along the depth or width direction of the cabin 110, to maximize space utilization and improve connection strength. Furthermore, the third plate 233 can also provide some support and reinforcement to the second plate 232, preventing bending deformation of the second plate 232 when the first limiting part 240 abuts against the cover 120 or the connecting rod assembly 220, thereby ensuring the overall structural stability and service life of the hinge component 200.

[0040] In some implementations, refer to Figure 1 As shown, a telescopic member 400 is provided between the cover 120 and the cabin 110 to support the cover 120 and the cabin 110 when they are opened and closed relative to each other. The telescopic member 400 can be an elastic support element such as a gas spring, hydraulic rod, or damper, with one end connected to the cabin 110 and the other end connected to the cover 120. When the cover 120 is open, the telescopic member 400 provides upward support force, helping the user to easily lift the cover 120, especially in scenarios where the cover 120 is heavy or needs to be opened frequently, effectively reducing the intensity of operation; while during the closing process of the cover 120, the telescopic member 400 slows down the falling speed of the cover 120 through its own damping effect, avoiding violent collision between the cover 120 and the cabin 110, reducing noise and component damage. The telescopic component 400 can also work in conjunction with the linkage assembly 220 of the hinge component 200. When the cover 120 is open, the supporting force of the telescopic component 400 and the limiting structure of the linkage assembly 220 work together to ensure that the cover 120 can be stably held at that angle position. This facilitates the user's inspection or operation of the internal components of the compartment 110 without the need for additional support tools, thus improving ease of use. For gas spring type telescopic components 400, a pressure adjustment device can be installed inside. According to the weight requirements of the cover 120 of different vehicle models, the supporting force can be changed by adjusting the gas pressure, enhancing the versatility and adaptability of the telescopic component 400.

[0041] In some implementations, refer to Figure 1 As shown, the vehicle's lateral direction, which is perpendicular to the vehicle's direction of travel, includes two hinge assemblies positioned on opposite sides of the cover 120. This design ensures more even force distribution on the cover 120 during opening and closing, preventing tilting of the cover 120 or premature damage to the hinge components 200 due to excessive force on one side. The two hinge assemblies can work together through a synchronous motion mechanism, ensuring consistent opening angles and movement trajectories on both sides of the cover 120, further improving the smoothness of opening and closing. Simultaneously, the dual-sided arrangement allows the other hinge assembly to temporarily assume some support and limiting functions in the event of a failure in one hinge assembly, providing dual protection for vehicle safety. During installation, the lateral spacing between the two hinge assemblies can be designed according to the width of the cover 120 to ensure a reasonable distribution of support points, effectively distributing the weight load of the cover 120 and extending the overall lifespan of the hinge system.

[0042] In this application, the hinge component 200 includes a rotating arm 210, a connecting rod assembly 220, a fixing plate 230, a first limiting part 240, and a bracket 250. The fixing plate 230 includes a first plate 231 and a second plate 232 arranged at an angle. The rotating arm 210 is connected to the cover 120. The connecting rod assembly 220 is rotatably connected to the rotating arm 210 and the first plate 231, respectively. The second plate 232 is connected to the cabin 110. The first limiting part 240 is connected to the side of the second plate 232 facing the cover 120. The first limiting part 240 is configured to abut against the cover 120 when the cover 120 and the cabin 110 are in a closed state. The bracket 250 includes a connecting part 251 and a mounting part 252 arranged at an angle. The connecting part 251 is connected to the second plate 232. The mounting part 252 extends toward the cover 120. The first limiting part 240 is connected to the mounting part 252. The fixing plate 230 adopts a structure in which the first plate 231 and the second plate 232 are set at an angle, which can better adapt to the installation space between the cabin 110 and the cover 120, making the layout of the hinge component 200 more compact and reasonable. After the rotating arm 210 is connected to the cover 120, the cover 120 can be opened and closed smoothly through the rotational cooperation of the connecting rod assembly 220 and the first plate 231. The connection between the second plate 232 and the cabin 110 provides a stable support foundation for the entire hinge component 200. By positioning the first limiting part 240 on the side of the second plate 232 facing the cover 120, when the cover 120 and the cabin 110 are closed, the first limiting part 240 can directly abut against the cover 120 to achieve the limiting function. During the opening of the cover 120, since the first limiting part 240 is connected to the second plate 232 on the side of the cabin 110 and does not flip with the cover 120, the problem of the limiting structure being exposed outside the cabin 110 is effectively avoided, reducing the risk of detachment and improving the overall perceived quality of the vehicle. The bracket 250 provides a stable mounting base for the first limiting part 240, increasing its stability during vehicle movement or frequent opening and closing of the cover 120.
