[0020] In this embodiment, the battery box body loaded on the vehicle needs to be protected by the frame assembly 01 during driving to reduce the vibration of the frame assembly 01. However, the commonly used dampers are expensive and have a single damping direction. Therefore, this embodiment discloses a battery box damping frame system. Figure 1 As shown, the battery box shock-absorbing frame system includes a frame component 01 and a shock-absorbing component 02.
[0021] like Figure 1 As 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 supported by the bottom bracket 12 and the bottom support beam 13, so that it is easy to install on the vehicle. Figure 2As shown, the first side of the support beam 14 is detachably connected to the bottom support beam 13. The second side of the support beam 14 is fixedly connected with a support shaft 15. 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 second side of the support beam 14. The first side and the second side of the support beam 14 are two sides perpendicular to each other. The first side can be a side in the height direction of the support beam 14, and the second side can be a side in the width direction of the support beam 14.
[0022] like Figure 2 As shown, the shock absorbing assembly 02 includes an elastic pad 21, a connector 22, an elastic ring 23, and a fixed ring 24. The bottom support beam 13, the elastic pad 21, and the connector 22 are arranged and fitted 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 connector 22 are detachably connected. Thus, the elastic pad 21 provides a shock absorbing effect along the axial direction of the support shaft 15 for the frame assembly 01, reducing the vibration generated by the frame assembly 01 when the vehicle is driving. The elastic ring 23 is sleeved on the support shaft 15. The connector 22 is detachably connected to the fixed ring 24. The fixed ring 24 is sleeved on the outside of the elastic ring 23. The connector 22 is detachably connected to the support beam 14. The elastic pad 21 and the elastic ring 23 can be spaced and respectively arranged on the two opposite sides of the connecting member 22, so that the connecting member 22 presses the elastic pad 21 to prevent the elastic pad 21 from falling off, and the elastic ring 23 is replaced more frequently and is arranged on the side of the connecting member 22 away from the support beam 14, which can be easily installed or disassembled for replacement. Through the above arrangement, the elastic ring 23 can achieve shock absorption along the circumference of the support shaft 15, and the connection conduction of the connecting member 22 can make the frame assembly 01 get a certain amount of shock absorption in different directions when the vehicle is driving, effectively protecting the battery box body. Furthermore, through a simple structural setting, the cost of investing in the shock absorption assembly 02 is reduced while achieving the shock absorption effect on the frame assembly 01.
[0023] In this embodiment, if Figure 2 , Figure 3 As shown, there are at least three groups of shock-absorbing assemblies 02 arranged along the length direction of the support beam 14. The length direction of the support beam 14 is perpendicular to the first side direction and the second side direction of the support beam 14, respectively. Three support shafts 15 are fixed on the support beam 14. The support shafts 15 correspond one by one to the shock-absorbing assemblies 02. By setting at least three groups of shock-absorbing assemblies 02, at least two groups of shock-absorbing assemblies 02 are located near both sides of the battery box accommodating frame 11. Since the length direction of the support beam 14 is the same as the driving direction of the vehicle, such a setting can make the shock-absorbing assembly 02 adapt to working conditions such as sudden braking or acceleration of the vehicle, enhance the shock-absorbing effect, and avoid excessive shaking of the frame assembly 01 affecting the driving of the vehicle.
[0024] In this embodiment, if Figure 3As shown, the first, second, and third groups of the shock absorbing components 02 are sequentially arranged along the length direction of the support beam 14. In the first and third groups of the shock absorbing components 02, as shown in FIG. Figure 4 As shown, the thickness of the two ends of the elastic ring 23 along the length direction of the support beam 14 is less than the thickness of the two ends of the elastic ring 23 along the height direction of the support beam 14. The first and third groups of shock absorbing components 02 are respectively arranged adjacent to the two sides of the battery box accommodating frame 11. During the driving process of the vehicle, acceleration or braking causes the frame component 01 near the end of the support beam 14 to have a tendency to tip over 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 elastic ring 23 is subjected to a large force (pressing down or pulling up) in the height direction of the support beam 14. By setting the thickness of the two ends of the elastic ring 23 in the vertical direction, that is, the upper and lower regions, to be thicker, and the thickness of the two ends in the horizontal direction, that is, the left and right regions, to be thinner, the service life of the elastic ring 23 can be extended to ensure the shock absorbing effect.
[0025] In this embodiment, if Figure 3 , Figure 4 As shown, in the first and third groups of shock absorbing components 02, 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, when 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, and the thickness of the top and bottom ends of the elastic ring 23 are greater than the thickness of the two horizontal ends. Furthermore, under the action of gravity of the frame assembly 01, the force on the top of the elastic ring 23 is greater than the force on the bottom. Through the above arrangement, the shock absorbing effect and anti-fatigue effect of the elastic ring 23 can be enhanced.
[0026] In this embodiment, if Figure 3 , Figure 5 As shown, in the second group of shock absorbing components 02, 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 located directly below the battery box containing frame 11, the force of the battery box containing frame 11 tilting vibration it bears when the vehicle is driving is relatively small. Through the above arrangement, the second group of shock absorbing components 02 can provide a stronger supporting force, so that the support beam 14 and the bottom support beam 13 are connected and tightened stably, so that 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 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. Thereby ensuring that the middle part of the shock absorbing component 02 provides a stable supporting force, and at the same time as a 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.
[0027] 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.
[0028] 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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] In this embodiment, this embodiment discloses a vehicle, which includes a battery box shock absorbing frame system of any one of the above embodiments. The vehicle may also include a battery box body and a frame. The battery box body is placed in the internal chamber of the battery box accommodating frame 11 of the battery box shock absorbing frame system. It is convenient to protect the battery box body and avoid the battery box body from being damaged by bumps.
[0033] The support beam 14 of the battery box shock absorbing frame system is detachably connected to the frame. The battery box shock absorbing frame system is located above the frame. The elastic pad 21 is vertically arranged. The support shaft 15 is horizontally arranged, and the support shaft 15 is parallel to the length direction of the frame, that is, the support shaft 15 is parallel to the driving direction. Therefore, the shock absorbing component 02 can be used to reduce the shock of the frame component 01, thereby reducing the vibration of the battery box body caused by driving actions such as acceleration or braking when the vehicle is traveling in any direction.
[0034] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
