Description

Technical Field

[0001] The present invention relates to the technical field of vehicle battery boxes, and more particularly, to a shock-absorbing frame system for a battery box and a vehicle. Background Art

[0002] During the driving process of a vehicle, vibrations are inevitably generated. In an electric vehicle, a battery box frame is used to protect the battery box. When the battery box frame is loaded onto the vehicle, due to the complex road conditions during driving, in order to reduce the vibrations of the battery box, a shock-absorbing system needs to be assembled between the frame and the vehicle mounting beam.

[0003] The existing shock-absorbing systems generally use dampers for connection. However, due to the relatively single shock-absorbing direction of the damper, the connection between the frame and the mounting beam is prone to cracking due to hard connection, posing a safety hazard. If multiple dampers are set to absorb shocks in multiple directions, the cost is relatively high and the occupied installation space is also large. Summary of the Invention

[0030] In this embodiment, during the driving process of the vehicle, it is necessary to protect the battery box body loaded on the vehicle through the frame assembly 01 and reduce the vibration of the frame assembly 01. However, the commonly used dampers are costly and have a single shock absorption direction. For this reason, this embodiment discloses a battery box shock absorption frame system. As Figure 1 shown, the battery box shock absorption frame system includes a frame assembly 01 and a shock absorption assembly 02.

[0031] As Figure 1 shown, the frame assembly 01 includes a battery box receiving frame 11, a bottom bracket 12, a bottom support beam 13 and a support beam 14. The battery box receiving frame 11 is detachably connected to the bottom bracket 12. The bottom bracket 12 is detachably connected to the bottom support beam 13. Thus, the battery box receiving frame 11 is carried by the bottom bracket 12 and the bottom support beam 13, which is convenient for installation on the vehicle. As Figure 2As shown, the first side of the support beam 14 is detachably connected to the bottom support beam 13. A support shaft 15 is fixedly connected to the second side of the support beam 14. Thus, the frame assembly 01 can be loaded onto the vehicle through the support shaft 15 and the support beam 14. The axis of the support shaft 15 is parallel to the orientation of the second side of the support beam 14. The first side and the second side of the support beam 14 are two mutually perpendicular sides. The first side can be one side in the height direction of the support beam 14, and the second side can be one side in the width direction of the support beam 14.

[0032] As Figure 2 shown, the shock absorption assembly 02 includes an elastic pad 21, a connecting piece 22, an elastic ring 23, and a fixing ring 24. The bottom support beam 13, the elastic pad 21, and the connecting piece 22 are arranged and attached in sequence along a direction parallel to the axis of the support shaft 15. The bottom support beam 13, the elastic pad 21, and the connecting piece 22 are detachably connected to each other. Thus, the elastic pad 21 provides a shock absorption effect for the frame assembly 01 in the axial direction of the support shaft 15, reducing the vibration generated by the frame assembly 01 during vehicle driving. The elastic ring 23 is sleeved on the support shaft 15. The connecting piece 22 is detachably connected to the fixing ring 24. The fixing ring 24 is sleeved on the outside of the elastic ring 23. The connecting piece 22 is detachably connected to the support beam 14. The elastic pad 21 and the elastic ring 23 can be arranged at intervals and on the opposite sides of the connecting piece 22 respectively, so that the connecting piece 22 presses the elastic pad 21 to prevent the elastic pad 21 from falling off, while the elastic ring 23 needs to be replaced more frequently. By arranging it on the side of the connecting piece 22 away from the support beam 14, it is convenient for installation or disassembly and replacement. Through the above arrangement, shock absorption in the circumferential direction of the support shaft 15 can be achieved through the elastic ring 23. Through the connection and conduction of the connecting piece 22, the frame assembly 01 can obtain a certain degree of shock absorption in different directions during vehicle driving, effectively protecting the battery box body. Furthermore, through a simple structural arrangement, while reducing the cost of the shock absorption assembly 02, the shock absorption effect on the frame assembly 01 is achieved.

[0033] In this embodiment, as Figure 2 、 Figure 3 shown, at least three groups of shock absorption assemblies 02 are arranged along the length direction of the support beam 14. The length direction of the support beam 14 is perpendicular to the orientations of the first side and the second side of the support beam 14 respectively. Three support shafts 15 are fixed on the support beam 14. The support shafts 15 correspond to the shock absorption assemblies 02 one by one. By arranging at least three groups of shock absorption assemblies 02, at least two groups of shock absorption assemblies 02 are located near both sides of the battery box accommodation frame 11. Since the length direction of the support beam 14 is the same as the driving direction of the vehicle, such an arrangement can enable the shock absorption assembly 02 to adapt to working conditions such as sudden braking or acceleration of the vehicle, enhance the shock absorption effect, and prevent the frame assembly 01 from shaking too much and affecting vehicle driving.

[0034] In this embodiment, as Figure 3As shown, the shock-absorbing components 02 are arranged in the first group, the second group, and the third group in sequence along the length direction of the support beam 14. In the shock-absorbing components 02 of the first group and the third group, as Figure 4 shown, the thickness of the elastic ring 23 at both ends along the length direction of the support beam 14 is less than the thickness of the elastic ring 23 at both ends along the height direction of the support beam 14. The first group and the third group of shock-absorbing components 02 are respectively disposed adjacent to both sides of the battery box accommodation frame 11. During the driving of the vehicle, acceleration or braking causes the frame component 01 near the end of the support beam 14 to have a tendency to tilt in the driving direction. For example, in the braking state, when the first group of shock-absorbing components 02 is close to the front of the vehicle, the first group of shock-absorbing components 02 has a tendency to press down, and when the third group of shock-absorbing components 02 is close to the rear of the vehicle, the first group of shock-absorbing components 02 has a tendency to rise. Therefore, the force borne by the elastic ring 23 along the height direction of the support beam 14 is relatively large (pressing down or pulling up). By setting the thickness of the vertical two ends of the elastic ring 23, that is, the upper and lower regions, to be thicker and the thickness of the horizontal two ends, that is, the left and right regions, to be thinner, the service life of the elastic ring 23 can be extended and the shock-absorbing effect can be ensured.

[0035] In this embodiment, as Figure 3 , Figure 4 shown, in the shock-absorbing components 02 of the first group and the third group, the thickness of the elastic ring 23 on the side close to the bottom bracket 12 is greater than the thickness of the elastic ring 23 on the side away from the bottom bracket 12. That is, in the state where the battery box shock-absorbing frame system is installed on the vehicle, the thickness of the top of the elastic ring 23 is greater than the thickness of the bottom end, and the thickness of the top and the bottom end of the elastic ring 23 are both greater than the thickness of the two horizontal ends. Further, under the gravity of the frame component 01, the force received above the elastic ring 23 is relatively greater than the force received below it. Through the above settings, the shock-absorbing effect and the anti-fatigue effect of the elastic ring 23 can be enhanced.

[0036] In this embodiment, as Figure 3 , Figure 5 shown, in the shock-absorbing components 02 of the second group, the thickness of the elastic ring 23 is evenly distributed in the circumferential direction. Since the second group of shock-absorbing components 02 is arranged in the middle area of the support beam 14 and is directly below the battery box accommodation frame 11, the force it bears due to the tilting vibration of the battery box accommodation frame 11 during vehicle driving is relatively small. Through the above settings, the second group of shock-absorbing components 02 can provide stronger support force, so that the support beam 14 is firmly and stably connected to the bottom support beam 13, and the vibration is transmitted to the shock-absorbing components 02 of the first group and the third group as much as possible. At the same time, in some other embodiments, the hardness of the elastic ring 23 of the second group of shock-absorbing components 02 is greater than the hardness of the elastic ring 23 of the first group or the third group of shock-absorbing components 02. Thus, it is ensured that the middle part of the shock-absorbing component 02 provides stable support force, and at the same time, as the fulcrum of the lever, the elastic force at the top of the elastic ring 23 in the shock-absorbing components 02 of the first group and the third group is maximized.

[0037] In other embodiments, the first group of shock absorbing components 02 near the front of the vehicle and the second group of shock absorbing components 02 in the middle are spaced at a first distance, and the third group of shock absorbing components 02 near the rear of the vehicle and the second group of shock absorbing components 02 in the middle are spaced at a second distance, and the first distance is smaller than the second distance. Therefore, in the face of actual driving conditions, since the number of braking times is usually more rapid and frequent than acceleration, by reducing the first distance, the moment of inertia generated by the inertial motion of the end of the battery box near the front of the vehicle tilting downward with the middle shock absorbing component 02 as the fulcrum can be smaller, thereby reducing driving risks and improving safety.

[0038] In this embodiment, if Figure 2 As shown, two supporting beams 14 are arranged opposite to each other. Thus, the two supporting beams 14 are convenient to be loaded on the vehicle, and further the battery box receiving frame 11 is evenly stressed, and the two supporting beams 14 can provide stable supporting force.

[0039] In this embodiment, if Figure 2 As shown, the shock absorbing components 02 are distributed on two opposite sides of the two support beams 14, so that the distance between the shock absorbing components 02 arranged along the width direction of the vehicle can be increased, so that the battery box with a longer size in the width direction of the vehicle can be stably supported by shock absorption. In addition, in order to facilitate the installation or removal of the shock absorbing component 02, the connecting member 22 of the shock absorbing component 02 can be fixed to the support beam 14 by multiple bolts.

[0040] In this embodiment, if Figure 2 , Figure 3 As shown, the battery box shock absorbing frame system may further include a damping assembly 03. One end of the damping assembly 03 is detachably connected to the bottom support beam 13, and the other end is detachably connected to the battery box receiving frame 11. Two damping assemblies 03 are distributed on both sides of the battery box receiving frame 11 along the length direction of the support beam 14. Thus, the shock absorbing effect of the frame assembly 01 can be enhanced, and the tilting of the frame assembly 01 in the driving direction or the length direction of the frame assembly 01 when the vehicle is driving can be reduced.

[0041] In this embodiment, if Figure 1 As shown, the shock absorbing component 02 also includes a protective cover 25. The protective cover 25 is detachably connected to the connecting member 22. The protective cover 25 and the connecting member 22 surround and form a accommodating chamber. The elastic ring 23 and the fixing ring 24 are both arranged in the accommodating chamber. Through the protection of the dustproof cover, the shock absorbing component 02 can be prevented from foreign objects affecting the shock absorbing effect of the elastic ring 23 when it is loaded and used, and the dustproof cover can prevent the elastic ring 23 from falling off, pressing the end of the connecting member 22 close to the support beam 14, so that the connection between the shock absorbing component 02 and the frame component 01 is tighter.

[0042] In this embodiment, the present disclosure discloses a vehicle, which includes a shock-absorbing frame system for a battery box as described in any one of the above embodiments. The vehicle may further include a battery box body and a vehicle frame. The battery box body is placed in the inner cavity of the battery box accommodating frame 11 of the shock-absorbing frame system for the battery box, which is convenient for protecting the battery box body and avoiding damage to the battery box body due to collision.

[0043] The support beam 14 of the shock-absorbing frame system for the battery box is detachably connected to the vehicle frame. The shock-absorbing frame system for the battery box is located above the vehicle frame. The elastic pad 21 is arranged vertically. The support shaft 15 is arranged horizontally, and the support shaft 15 is parallel to the length direction of the vehicle frame, that is, the support shaft 15 is parallel to the driving direction. Thus, the frame assembly 01 can be shock-absorbed by the shock-absorbing assembly 02, and the vibration generated by the battery box body during vehicle driving in any direction due to driving actions such as acceleration or braking can be reduced.

[0044] Those of ordinary skill in the art can understand that the above embodiments are specific examples for implementing the present disclosure, and in practical applications, various changes can be made in form and details without departing from the scope of the present disclosure.
