[0031] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0032] Reference below Figure 1-Figure 6 A battery 50 fixing structure according to an embodiment of the present invention is described, and the present invention also provides a vehicle.

[0033] Reference Figure 1-6 As shown, the battery 50 fixing structure of the embodiment of the utility model includes: a vehicle body longitudinal beam 10 and a mounting bracket 20.

[0034] The mounting bracket 20 includes: a tray 21 and a support member 22. The lower end of the battery 50 is fixed to the tray 21. One end of the support member 22 is connected to the tray 21 and the other end is connected to the vehicle body longitudinal beam 10. The mounting bracket 20 is used to support the battery 50 and fix the battery 50 on the vehicle body longitudinal beam 10. The battery 50 is placed above the tray 21 and fixedly connected to the tray 21. One end of the support member 22 is fixed to the bottom of the tray 21 and the other end is fixedly connected to the vehicle body longitudinal beam 10. In this way, the battery 50 can be fixed to the vehicle body longitudinal beam 10 through the mounting bracket 20. When the tray 21 or the support member 22 in the mounting bracket 20 is damaged, the tray 21 and the support member 22 can be disassembled and replaced, and the maintenance speed is fast.

[0035] Furthermore, the battery 50 can be fixed to the right front longitudinal beam of the vehicle body through the mounting bracket 20, the tray 21 is fixed to the longitudinal beam 10 of the vehicle body in the up and down directions, and the support member 22 is fixed to the longitudinal beam 10 of the vehicle body in the front and rear directions. The mounting bracket 20 is fixed in two directions at the same time. When the vehicle body vibrates, the mounting bracket 20 is not easy to loosen at the same time, thereby improving the stability of the battery 50 and facilitating the stable power supply of the battery 50.

[0036] Among them, in the left-right direction, the contact area of ​​the tray 21 and the vehicle body longitudinal beam 10 is larger than the area where the tray 21 does not contact the vehicle body longitudinal beam 10. In this way, the contact area of ​​the tray 21 and the vehicle body longitudinal beam 10 is larger, the force-bearing area is larger, and the battery 50 is fixed on the vehicle body longitudinal beam 10 more stably, ensuring the stable power supply of the battery 50 and improving the quality of the whole vehicle.

[0037] Therefore, by providing an installation bracket 20 that is easy to disassemble and assemble, the maintenance speed of the installation bracket 20 can be improved, and the installation bracket 20 can be fixed in two directions to increase the contact area between the tray 21 and the vehicle body longitudinal beam 10. When the vehicle body vibrates, the installation bracket 20 is not easy to loosen at the same time, which can improve the stability of the battery 50 and is beneficial to the stable power supply of the battery 50.

[0038] Reference Figure 1-6 As shown, the support member 22 includes: a support portion 221, a first connection portion 222 and a second connection portion 223. The support portion 221 is arranged between the first connection portion 222 and the second connection portion 223. The first connection portion 222 is fixedly connected to the tray 21, and the second connection portion 223 is connected to the side of the vehicle body longitudinal beam 10. Specifically, the support member 22 is composed of three parts. The first connection portion 222, the support portion 221 and the second connection portion 223 are bent to form a support structure for supporting the tray 21. The first connection portion 222 is fixedly connected to the tray 21, and the second connection portion 223 is fixedly connected to the side of the vehicle body longitudinal beam 10. The mounting bracket 20 can be replaced by disassembling the second connection portion 223.

[0039] Reference Figure 1-6As shown, the support portion 221 is tilted, and the angle between the support portion 221 and the horizontal plane is α, and α satisfies the relationship: 40°≤α≤50°. That is. After the three parts of the support member 22 are bent relative to each other, the angle formed by the support portion 221 and the horizontal plane is not less than 40° and not greater than 50°. The support portion 221 within this range can better support the tray 21. If the angle is too small, the support portion 221 approaches horizontality, and the tray 21 is supported only by the second connecting portion 223. The supporting force is insufficient, and the battery 50 is easy to shake. If the angle is too large, the support portion 221 approaches verticality, and the area that can support the tray 21 is small, and the supporting effect is poor.

[0040] Furthermore, the angle between the first connection portion 222 and the horizontal direction is smaller than the angle between the support portion and the horizontal plane. Preferably, the angle between the first connection portion 222 and the horizontal direction is zero, so that the first connection portion 222 remains horizontal with the tray 21, the force-bearing area is maximized, and greater support can be provided for the tray 21, and the position of the battery 50 is more stable.

[0041] The angle between the second connection portion 223 and the horizontal direction is greater than the angle between the support portion 221 and the horizontal plane. In this way, the second connection portion 223 approaches the vertical direction and can better fit with the side of the vehicle body longitudinal beam 10, thereby improving the stability of the second connection portion 223 and the vehicle body longitudinal beam 10.

[0042] Reference Figure 1-6 As shown, the battery 50 fixing structure also includes: a pressing plate 30 and a connecting member 40. The pressing plate 30 is pressed on the upper end of the battery 50. One end of the connecting member 40 is connected to the tray 21 and the other end is connected to the pressing plate 30. The tray 21 and the pressing plate 30 are connected by the connecting member 40. The pressing plate 30, the connecting member 40 and the tray 21 are connected in sequence from top to bottom, so that the pressing plate 30 fits the battery 50, and the battery 50 is fixed on the tray 21 to prevent the battery 50 from moving up and down. In addition, the pressing plate 30 is provided with a mounting hole, and the pressing plate 30 and the connecting member 40 can be fixed by installing nuts.

[0043] Furthermore, two limiting steps are provided at one end of the pressure plate 30 facing the battery 50, and the two limiting steps are arranged at intervals in the front-to-back direction, and the limiting steps abut against the side of the battery 50 in the front-to-back direction. In this way, the position of the battery 50 in the front-to-back direction can be limited, and the battery 50 is prevented from moving when the vehicle vibrates, thereby improving the stability of the vehicle.

[0044] Reference Figure 1-6As shown, the tray 21 is provided with limiting flanges 211 on both sides in the front-to-back direction, the limiting flanges 211 abut against the side surfaces of the battery 50, and one end of the connector 40 is connected to the limiting flange 211. Specifically, a hook structure may be provided below the connector 40, and a through hole or a slot may be provided on the limiting flange 211. The lower end of the connector 40 is clamped on the limiting flange 211, so that the connector 40 and the tray 21 can be fixed. Furthermore, the limiting flanges 211 are provided on both sides in the front-to-back direction of the tray 21, and are used to limit the position of the battery 50 in the front-to-back direction, prevent the battery 50 from moving when the vehicle vibrates, and improve the stability of the vehicle.

[0045] Reference Figure 1-6 As shown, a first mounting hole 212 is provided on the tray 21, a second mounting hole is provided on the vehicle body longitudinal beam 10, and the fastener is fixedly connected to the second mounting hole after passing through the first mounting hole 212; and a third mounting hole 224 is provided on the support member 22, a fourth mounting hole is provided on the vehicle body longitudinal beam 10, and the fastener is fixedly connected to the fourth mounting hole after passing through the third mounting hole 224.

[0046] That is to say, the tray 21 and the vehicle body longitudinal beam 10 are connected by fasteners, and the support member 22 and the vehicle body longitudinal beam 10 are also connected by fasteners. When repairing and replacing the mounting bracket 20, it is only necessary to remove the fasteners, which has a fast repair speed and high positioning accuracy without damaging the vehicle body condition.

[0047] The fastener may be a bolt, and further, may be an anti-loosening bolt.

[0048] Furthermore, the first mounting hole 212, the second mounting hole, the third mounting hole 224 and the fourth mounting hole can be two or more, and the first mounting hole 212, the second mounting hole, the third mounting hole 224 and the fourth mounting hole are opened by laser cutting or metal punching, and the positioning accuracy is high.

[0049] Reference Figure 1-6 As shown, the tray 21 is provided with a fifth mounting hole 213, the support member 22 is provided with a sixth mounting hole 225, and the fastener passes through the fifth mounting hole 213 and is fixedly connected with the sixth mounting hole 225. That is, the first connection portion 222 of the support member 22 is fixed to the tray 21 by the fastener, wherein the fastener may be a bolt, and the bolt may be screwed with a back-welded nut or with a rivet nut. In addition, the connection method of the support member 22 and the tray 21 may also be riveting.

[0050] Alternatively, in some embodiments, the tray 21 and the support member 22 may be an integrally formed structure, so that the mounting bracket 20 has greater strength, reduces the assembly process, and improves production efficiency.

[0051] Alternatively, in other embodiments, the tray 21 and the support member 22 may be connected by welding.

[0052] Since the support member 22 and the tray 21 can be connected in a variety of ways, there is a large room for selection during production, which facilitates adjustment of the vehicle assembly process according to actual conditions during production.

[0053] Reference Figure 1-6 As shown, the tray 21 and / or the support member 22 are also provided with weight-reducing holes 23. The weight-reducing holes 23 can be used to effectively reduce the weight of the mounting bracket 20, reduce the use of materials, and reduce production costs.

[0054] The vehicle according to the second embodiment of the utility model includes a battery 50 fixing structure. By improving the battery 50 fixing structure and providing a mounting bracket 20 that can be quickly disassembled and assembled, the maintenance speed of the mounting bracket 20 can be improved, and the mounting bracket 20 is fixed in two directions to increase the contact area between the tray 21 and the vehicle body longitudinal beam 10. When the vehicle body vibrates, the mounting bracket 20 is not easy to loosen at the same time, which can improve the stability of the battery 50 and is conducive to the stable power supply of the battery 50. There are many ways to connect the support member 22 and the tray 21, and there is a large space for selection during production, which is convenient for adjusting the vehicle assembly process according to actual conditions during production.
