[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are set forth in order to provide a comprehensive understanding of the present application. However, it will be apparent to those skilled in the art that the present application can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the well-known structures and technologies are not shown in order to avoid unnecessary ambiguity in the present application; and, for clarity, the sizes of some structures may be exaggerated. In addition, the features, structures, or characteristics described below may be combined in any suitable manner in one or more embodiments.

[0035] The directional words appearing in the following description refer to the directions shown in the figures and do not limit the vehicle chassis structure and vehicle of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] In order to better understand this application, Figures 1 to 7 The bumper device and the vehicle according to the embodiment of the application are described in detail.

[0037] Currently, traditional bumpers on vehicles cannot sensitively control vehicle braking after facing a single-sided collision, causing the collision to cause continuous damage to the occupants and the vehicle itself.

[0038] Here, a single-side impact refers to an impact on both sides of the bumper in the extension direction.

[0039] Based on this, an embodiment of the present application provides a bumper device, which is beneficial to improving the sensitivity of triggering vehicle braking under various impact positions. The bumper device can be produced and sold separately as an independent component. At the same time, it can also be used in vehicles and as a component of the vehicle, which can help improve the safety of the vehicle.

[0040] The bumper device provided in the embodiment of the present application can be a front bumper, a rear bumper, or a side bumper on the side of the vehicle, and the present application does not limit this.

[0041] Please also refer to Figures 1 to 4 The embodiment of the present application proposes a bumper device for a vehicle, comprising a bumper body 10, a buffer device, a connecting assembly, and a control assembly 40. The buffer device is arranged on one side of the bumper body 10 along a first direction X. The buffer device includes a pair of buffer members 21, and the pair of buffer members 21 are spaced apart along a second direction Y intersecting the first direction X. The connecting assembly is connected between the bumper body 10 and the buffer device. The connecting assembly includes a pair of connecting members 31 spaced apart along the second direction Y, one of the connecting members 31 being rotatably connected to one of the buffer members 21, and the other connecting member 31 being rotatably connected and movably connected to the other buffer member 21 along the second direction Y. The control assembly 40 is arranged on a side of the connecting assembly away from the bumper body 10 along the first direction X, and is configured to control vehicle braking. The buffer member 21 is movable along the first direction X. When the buffer member 21 moves to a preset position, the control assembly 40 is triggered to control vehicle braking.

[0042] The bumper device and vehicle proposed in the embodiments of the present application include a bumper body 10, a buffer device, a connecting assembly and a control assembly 40. The connecting assembly is connected between the bumper body 10 and the buffer device, and includes connecting members 31 arranged in pairs and spaced apart along the second direction Y. The buffer device includes buffer members 21 arranged in pairs and spaced apart along the second direction Y. By rotating one of the connecting members 31 to connect to one of the buffer members 21, and rotating the other connecting member 31 to connect to the other buffer member 21 movably along the second direction Y, when the bumper body 10 is impacted at any side position in the second direction Y, the bumper body 10 can be deflected to cause the buffer member 21 to move along the first direction X. When any of the relatively arranged buffer members 21 moves to a preset position, the control assembly 40 can be triggered to control vehicle braking, which helps to improve the sensitivity of triggering vehicle braking under various impact positions.

[0043] Among them, the first direction X can be the length direction of the vehicle, that is, the driving direction of the vehicle, the second direction Y can be the width direction of the vehicle, that is, the direction horizontally and perpendicular to the driving direction of the vehicle, and the third direction Z can be the height direction of the vehicle.

[0044] The bumper body 10 is used to withstand the impact suffered by the vehicle. Optionally, the bumper body 10 can be configured as a plate-like structure, or the bumper body 10 can be configured as a combination of plate-like structures.

[0045] Optionally, the bumper body 10 can be made of aluminum alloy material, which can provide good protection while meeting the lightweight design requirements, preventing the heavier structure from accidentally touching the control component 40 due to inertia during vehicle operation to brake the vehicle, and can also reduce abnormal noise generated during vehicle operation. In addition, aluminum alloy material has better corrosion resistance and can be suitable for various operating environments.

[0046] The buffer member 21 may be configured as a rod-shaped structure, a cylindrical structure, an axis structure, etc., which are extended along the first direction X.

[0047] Optionally, one of the connecting members 31 is rotatably connected to one of the buffer members 21 with the third direction Z as the axis, and another connecting member 31 is also rotatably connected to another of the buffer members 21 with the third direction Z as the axis, and this connecting member 31 can also be movably connected to this buffer member 21 along the second direction Y, so that when the bumper body 10 is hit at any side position in the second direction Y, the bumper body 10 can swing to drive the buffer member 21 to move along the first direction X.

[0048] Optionally, one of the connecting members 31 may be configured as a bearing structure, and one of the buffer members 21 may be configured as a connecting shaft structure having at least a portion rotatably engaged with the bearing structure, so as to achieve a rotational connection between the two.

[0049] Optionally, one of the connecting members 31 may be configured as a turbine structure, and one of the buffer members 21 may be configured as a worm structure at least partially rotating and moving with the turbine structure to achieve a rotational and moving connection between the two.

[0050] The buffer 21 can trigger the control component 40 to control vehicle braking. Optionally, the buffer 21 and the control component 40 can be set to a contact trigger structure, that is, when the buffer 21 moves along the first direction X to contact the control component 40, the control component 40 is triggered to control vehicle braking. Of course, the buffer 21 and the control component 40 can also be set to a non-contact trigger structure, that is, when the buffer 21 moves along the first direction X to a preset position, it can trigger the control component 40 to control vehicle braking through a magnetic induction signal or a light sensing signal.

[0051] Optionally, the control component is connected to the vehicle's control system signal to control vehicle braking.

[0052] Among them, the preset position can be set according to different triggering methods or the user's different sensitivity requirements for controlling vehicle braking, and this application does not limit this.

[0053] Optionally, the control assembly 40 may be disposed between the buffer devices that are disposed in pairs, thereby reducing the space occupied by the bumper device and improving the compactness of the structure.

[0054] The bumper device provided in the embodiment of the present application is capable of deflecting the bumper body 10 regardless of which side of the bumper body 10 is impacted in the second direction Y. For example, when the bumper body 10 is impacted on one side in the second direction Y, the bumper body 10 rotates clockwise or counterclockwise under the action of the buffer device and the connecting assembly to deflect. Specifically, the length dimension between the impacted side of the bumper body 10 and the control assembly 40 in the first direction X is smaller than the length dimension between the other side of the bumper body 10 and the control assembly 40 in the first direction X. The bumper body 10 pushes the buffer member 21 to move in the first direction X. The buffer member 21 closer to the impacted side of the bumper body 10 moves faster to a preset position, triggering the control assembly 40 to control vehicle braking. However, when the bumper body 10 is impacted in the middle of the bumper body 10 in the second direction Y, the bumper body 10 does not deflect to push the buffer member 21 in the first direction X. This allows the control assembly to be quickly triggered to control vehicle braking regardless of the impact on any part of the bumper body 10, thereby improving sensitivity.

[0055] like Figure 3 As shown, when the bumper body 10 is hit on the left side in the figure, the bumper body 10 deflects and the buffer member 21 on the left side moves faster along the first direction X to trigger the control component 40 to control vehicle braking.

[0056] Therefore, the bumper device provided in the embodiment of the present application can quickly trigger vehicle braking no matter which position of the bumper body 10 is hit, which is conducive to improving the sensitivity of triggering vehicle braking and avoiding continuous damage to people, facilities and the vehicle itself caused by the collision.

[0057] See also Figures 1 to 6According to one aspect of an embodiment of the present application, in the third direction Z, each connecting member 31 has a through first circular hole 31a, one of the buffer members 21 has a through second circular hole 21a on the side close to the bumper body 10 along the first direction X, and another buffer member 21 has a through oval hole 21b on the side close to the bumper body 10 along the first direction X, the projection of one first circular hole 31a overlaps with the projection of the second circular hole 21a, and the projection of the other first circular hole 31a overlaps with the projection of the oval hole 21b, and the first direction X, the second direction Y and the third direction Z intersect.

[0058] This arrangement helps ensure the effectiveness of the bumper body 10 being able to deflect after the bumper device is impacted, and is convenient for processing and assembly, thereby reducing costs.

[0059] A connecting member 31 is arranged corresponding to a buffer member 21, and the connecting member 31 and the buffer member 21 are overlapped in the third direction Z, so that the projection of one of the first circular holes 31a overlaps with the projection of the second circular hole 21a, and the projection of the other first circular hole 31a overlaps with the projection of the oval hole 21b.

[0060] Optionally, each connecting member 31 is respectively connected and fixed to a buffer member 21 by a pin shaft. It can be understood that a pin shaft is set through the first circular hole 31a and the second circular hole 21a to connect one of the connecting members 31 and one of the buffer members 21, so that this connecting member 31 can be rotatably connected to this buffer member 21, and a pin shaft is set through the first circular hole 31a and the oval hole 21b to connect another connecting member 31 and another buffer member 21, so that this connecting member 31 can be rotatably connected and can be movably connected to this buffer member 21 along the second direction Y.

[0061] Optionally, the connecting member 31 may be configured as a plate-shaped structure, and the buffer member 21 may also be configured as a plate-shaped structure, and the two may be spaced apart in the third direction Z or may be abutted in the third direction Z.

[0062] The oval-shaped hole 21 b is extended along the second direction Y, so that the connecting member 31 can be movably connected to the buffer member 21 having the oval-shaped hole 21 b along the second direction Y.

[0063] It can be understood that the first circular hole 31a cooperates with the second circular hole 21a to limit the movement of the bumper body 10 in the second direction Y, and the first circular hole 31a cooperates with the waist circular hole 21b to provide freedom to enable the bumper body 10 to swing, thereby triggering vehicle braking, which helps to reduce the risk of serious damage to the vehicle.

[0064] Please continue reading Figures 4 to 6According to one aspect of an embodiment of the present application, the connecting member 31 has a connecting groove 311 connected to the first circular hole 31a, and the buffer member 21 includes a connecting block 211 and a drive shaft 212 connected to each other. The connecting block 211 is arranged in the connecting groove 311 and connected to the connecting member 31, wherein one of the connecting blocks 211 has a second circular hole 21a, and the other connecting block 211 has a waist circular hole 21b.

[0065] Among them, the connecting block 211 refers to a structure with a certain volume or a certain thickness. By being set in this way, the connecting block 211 has a higher strength, preventing the connecting block 211 from tilting after the bumper body 10 is hit, causing the bumper body 10 to sink, thereby ensuring the reliability of the bumper device.

[0066] Optionally, the connecting block 211 and the drive shaft 212 can be provided as an integrally formed structure to improve processing efficiency. Of course, the connecting block 211 and the drive shaft 212 can also be provided separately and connected into a whole by a fixed connection method such as welding or gluing, which is conducive to reducing processing difficulty and improving usage flexibility.

[0067] Optionally, each connecting member 31 has a connecting groove 311 connected to the first circular hole 31 a , and in the second direction Y, the projection of each connecting member 31 is a C-shaped structure.

[0068] Optionally, the connecting member 31 can be manufactured by machining, which can prevent deformation or loosening during long-term use, thereby improving the service life of the connecting member 31 and thus improving the service life of the bumper device.

[0069] See also Figures 4 to 7 According to one aspect of an embodiment of the present application, the bumper device further includes a buffer assembly 50, each buffer member 21 is provided with a buffer assembly 50, the buffer assembly 50 includes a telescopic member 51 and a limiting member 52, the telescopic member 51 is provided on the periphery of the buffer member 21 on the side away from the bumper body 10 along the first direction X, and the limiting member 52 is connected to the periphery of the buffer member 21 on the side close to the bumper body 10 along the first direction X. In the first direction X, the projection of the limiting member 52 overlaps with the projection of the telescopic member 51.

[0070] By providing the buffer assembly 50 , a buffering and energy-absorbing effect is generated when the bumper body 10 is impacted, thereby preventing the bumper device from being damaged and improving the safety and reliability of the bumper device.

[0071] In the first direction X, the projection of the limiting member 52 overlaps with the projection of the telescopic member 51. That is, when the buffer member 21 moves along the first direction X, it will drive the limiting member 52 to move along the first direction X, thereby abutting and pushing the telescopic member 51 to contract to buffer the impact.

[0072] Optionally, the limiting member 52 is provided at the middle end of the buffer member 21 in the first direction X. When the bumper body 10 is impacted, the limiting member 52 can move along the first direction X with the buffer member 21 to apply pressure to the telescopic member 51 .

[0073] Exemplarily, the limiting member 52 is disposed at the middle end of the driving shaft 212 in the first direction X.

[0074] Optionally, the telescopic member 51 is sleeved on the outer periphery of the buffer member 21, and one end of the telescopic member 51 close to the bumper body 10 in the first direction X can be abutted against the limit member 52, and the other end can be fixed by other components. When the bumper body 10 is hit, the telescopic member 51 can be squeezed and deformed by the limit member 52 to buffer the impact.

[0075] Among them, the telescopic member 51 has a structure that can undergo elastic deformation and restore its shape, so that when the obstacle that hits the bumper body 10 is removed, the telescopic member 51 can give a thrust to the limit member 52 along the first direction X, thereby pushing the buffer member 21 and the bumper body 10 to move away from the control component 40 along the first direction X, so that it returns to its initial position.

[0076] like Figure 7 As shown, according to one aspect of an embodiment of the present application, the telescopic member 51 includes a spring 511 and a connecting tube 512. The connecting tube 512 is sleeved on the outer periphery of the buffer 21 and includes a tube body and a cover plate. The cover plate is connected to the side of the tube body away from the bumper body 10 along the first direction X. The limit member 52 and the spring 511 are respectively arranged between the tube body and the buffer 21. The spring 511 is connected to the cover plate. The buffer 21 can move along the first direction X relative to the connecting tube 512.

[0077] By arranging the spring inside the connecting tube 512, corrosion caused by external impurities such as rainwater can be reduced. In addition, the spring 511 has a good energy absorption effect and can be reused repeatedly, which is beneficial to improving the service life, thereby improving the service life of the bumper device.

[0078] It is understandable that the connecting tube 512 can be fixed to a component on the vehicle so that it is fixed relative to the buffer member 21 to ensure that the spring 511 connected to the connecting tube 512 can be effectively compressed and released to extend.

[0079] See also Figure 1 and Figure 4According to one aspect of an embodiment of the present application, the bumper device also includes an adapter assembly 60, which includes an adapter 61 and an adapter frame 62 that are connected. The adapter 61 is connected between the two connecting cylinders 512, the control assembly 40 is connected to the connecting member 31, and the adapter frame 62 is configured to be connected to a component on the vehicle.

[0080] By providing the adapter assembly 60, positioning and installation are facilitated, and when the bumper device needs to be repaired or replaced, it is only necessary to separate the adapter 61 from the adapter frame 62, which is convenient for disassembly and assembly and helps reduce maintenance costs.

[0081] Other components in the bumper device can be connected to components on the vehicle through the adapter frame 62. Optionally, the adapter frame 62 is connected to the body of the vehicle and connected to the front of the vehicle so that the bumper device can better play a protective role.

[0082] Optionally, when the bumper device is severely impacted and its own structure is severely damaged, for example, when the buffer assembly 50 cannot absorb energy, the adapter 61 can be disassembled with corresponding parts, which is convenient for disassembly and assembly. During assembly, it is only necessary to assemble the adapter 61 to the adapter frame 62 without the need for assembly with components on the vehicle, which helps to reduce the difficulty of operation and help to reduce maintenance costs.

[0083] Optionally, the connecting member 31 and the connecting tube 512 are arranged to be connected by welding. Of course, they can also be detachably connected by fasteners such as bolts, screws, and studs.

[0084] After the vehicle is hit, when the bumper body 10 drives the buffer member 21 to move along the first direction X, the limiter 52 compresses the spring 511 to contract until the connecting block 211 abuts against the connecting tube 512 , at which point the bumper device reaches its collapse limit.

[0085] According to one aspect of an embodiment of the present application, the connecting member 31 has a strip-shaped hole 61a that passes through along the second direction Y, and the control component 40 is arranged in the strip-shaped hole 61a. The strip-shaped hole 61a extends along the first direction X so that the position of the control component 40 in the first direction X is adjustable.

[0086] By setting in this manner, the position of the control component 40 can be adjusted according to actual needs to adjust the sensitivity of the vehicle braking feedback, thereby helping to improve the flexibility and applicability of the bumper device.

[0087] The strip-shaped hole 61 a extends along the first direction X. The control component 40 can be fastened in the strip-shaped hole 61 a to be fixedly disposed with the connecting member 31 , so as to facilitate adjustment of the position of the control component 40 in the first direction X.

[0088] Please continue reading Figure 1 and Figure 4 According to one aspect of an embodiment of the present application, the control component 40 includes control members 41 spaced apart along the second direction Y, and the bumper device further includes a trigger member 70. Each buffer member 21 is provided with a trigger member 70 on a side away from the bumper body 10 along the first direction X. When the projection of the trigger member 70 in the second direction Y overlaps with the control member 41, the control component 40 is triggered to control vehicle braking.

[0089] This arrangement helps ensure that the bumper device can effectively control the vehicle's braking after a collision.

[0090] Each buffer member 21 is provided with a trigger member 70, and the control assembly 40 includes control members 41 spaced apart along the second direction Y, so that when the bumper body 10 is impacted, no matter which side of the bumper body 10 in the second direction Y moves more along the first direction X, the control member 41 can be triggered to brake the vehicle, thereby improving sensitivity.

[0091] Optionally, the trigger member 70 and the control member 41 are spaced apart in the second direction Y, and a photosensitive control method can be used to set the trigger mode of the control member 41. The sensitivity is high, and the trigger member 70 and the control member 41 can be prevented from being easily deformed or damaged after being set to a contact structure, thereby improving safety and reliability and extending service life.

[0092] Optionally, the trigger member 70 may be configured as a baffle and detachably connected to the buffer member 21 via fasteners such as bolts, screws, and studs.

[0093] According to one aspect of an embodiment of the present application, the bumper body 10 includes a bottom plate 11 and a side plate 12 connected to the bottom plate 11.
