DETAILED DESCRIPTION

[0038] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0040] With the improvement of people's living standards, cars are used more and more frequently in people's daily lives and have gradually become one of the important means of transportation for people. At the same time, as people's requirements for cars are getting higher and higher, the automobile industry is developing rapidly. Automobile manufacturers not only need to consider the high-end performance of the car itself, but also need to pay attention to the safety of the car.

[0041] The embodiment of the present application provides a vehicle, which may include an engine and a chassis. It is understandable that the vehicle may be an electric vehicle, a hybrid vehicle, a solar vehicle, etc., and the specific type of the vehicle is not specifically limited here.

[0042] Among them, the engine is the power device of the vehicle, which can provide power for the vehicle to move on the ground.

[0043] The chassis can be used to install the engine and other components and assemblies of the vehicle to form the overall shape of the vehicle, and receive the power of the engine to make the vehicle move and ensure normal driving.

[0044] The vehicle may also include a battery that provides electrical energy to the vehicle's electrical systems and maintains the vehicle's power supply.

[0045] In the related art, a double-layer tray is generally used to limit the position of the battery of the car. The battery of the car is placed in the middle of the double-layer tray, and the battery is limited by the clamping of the double-layer tray. However, during use, the double-layer tray cannot effectively limit the battery, and the battery is prone to loosening and displacement.

[0046] During the driving process of the vehicle, the battery may become loose and shifted, which may easily cause damage such as battery casing rupture and electrolyte leakage. Not only will the battery life be affected, but the electrolyte is corrosive, posing a threat to surrounding parts and even causing fire and electrical failure, increasing the safety risks of people in the vehicle.

[0047] Based on this, the embodiment of the present application provides a battery tray structure. For ease of understanding, the C-pillar reinforcement structure provided by the embodiment of the present application is specifically introduced below in conjunction with the accompanying drawings.

[0048] Figure 1 is a schematic structural diagram of a battery tray structure 100 according to an exemplary embodiment. Figure 1 As shown, the battery tray structure 100 may include a bottom plate 1 and a limiting assembly 2. The bottom plate 1 has a bearing surface 11, and the bearing surface 11 may be used to bear and support the battery.

[0049] Along the first direction, both sides of the bottom plate 1 are respectively formed with first flanges 12 bent toward the side where the bearing surface 11 is located. Along the second direction, one side of the bottom plate 1 is formed with a second flange 13 bent toward the side where the bearing surface 11 is located. In this way, the first flanges 12 formed on both sides of the bottom plate 1 can limit the battery in the first direction.

[0050] The limiting assembly 2 is located on the side where the bearing surface 11 is located, and is detachably connected to the bottom plate 1. Figure 1 and Figure 2 , Figure 2It is a top view of a battery tray structure 100 according to an exemplary embodiment, in which a portion of the limiting assembly 2 is arranged opposite to the bearing surface 11 and spaced apart, and forms a first limiting groove 3 with the bottom plate 1, which opens toward the second flange 13. The bottom plate 1 and the limiting assembly 2 are detachably connected, which is convenient for users to clean and maintain, and convenient for users to take and place batteries.

[0051] In the battery tray structure 100 of the present application, the first flanges 12 formed on both sides of the bottom plate 1 can limit the battery in the first direction, the second flange 13 formed on one side of the bottom plate 1 and the limiting assembly 2 can limit the battery in the second direction, and the first limiting groove 3 can limit the battery in the up and down directions. The battery tray structure 100 has good stability in limiting, and the battery can be limited in different directions, and the battery is not easy to loosen or shift.

[0052] In some embodiments, see Figure 1 and Figure 3 , Figure 3 1 is a schematic diagram of a battery tray structure 100 according to an exemplary embodiment, wherein the limiting assembly 2 may include a first limiting member 21 and a second limiting member 22. A portion of the first limiting member 21 is opposite to and spaced from the bearing surface 11. The second limiting member 22 passes through the first limiting member 21 and is threadedly connected to the bottom plate 1.

[0053] It can be understood that the second limiting member 22 is threadedly connected to the bottom plate 1 , the second limiting member 22 is connected to the first limiting member 21 , and the first limiting member 21 is connected to the bottom plate 1 .

[0054] The second limiting member 22 and the bottom plate 1 can be installed and removed via the threaded connection, which facilitates maintenance, replacement and assembly of the battery tray structure 100 .

[0055] It should be noted that the second limiting member 22 and the base plate 1 may also have other connection methods, such as pin connection, snap connection, etc., which are not limited in the present application and can be selected according to actual conditions.

[0056] In some embodiments, Figure 1 As shown, the battery tray structure 100 also includes a first reinforcing rib 4, which is arranged on the first limiting member 21 and connected to the first limiting member 21. The first reinforcing rib 4 can increase the strength of the first limiting member 21 and further increase the stability of the battery tray structure 100.

[0057] In some embodiments, participating Figure 1The battery tray structure 100 may further include a third stopper 23. Along the second direction, the third stopper 23 is located on a side of the first stopper 21 away from the second flange 13 and is connected to the bottom plate 1. The third stopper 23 is connected to the bottom plate 1 to increase the connection strength between the bottom plate 1 and the stopper assembly 2.

[0058] The third limiting member 23 can also abut against the first limiting member 21. In this way, the first limiting member 21 can be limited to shake forward and backward and rotate, the friction generated by the first limiting member 21 when limiting the displacement of the battery can be reduced, the service life of the first limiting member 21 can be extended, and the structural strength of the battery tray structure 100 can be increased.

[0059] In some embodiments, Figure 1 As shown, the third limiting member 23 may include a connecting portion 231 and a limiting portion 232. The connecting portion 231 is connected to the bottom plate 1.

[0060] One end of the limiting portion 232 is connected to the connecting portion 231, and the other end of the limiting portion 232 extends in a direction away from the bottom plate 1, and the limiting portion 232 abuts against the first limiting member 21. In this way, since the other end of the limiting portion 232 extends in a direction away from the bottom plate 1, the limiting portion 232 can more conveniently abut against the first limiting member 21.

[0061] It should be noted that the connection portion 231 and the base plate 1 can be connected in different ways, which is not limited in the present application and can be selected according to actual conditions.

[0062] Exemplarily, the connection part 231 is welded to the bottom plate 1. The welding strength is high, which improves the connection strength between the connection part 231 and the bottom plate 1, so that the first limiter 21 can be better limited to shake and rotate forward and backward, reduce the friction generated by the first limiter 21 when limiting the displacement of the battery, and extend the service life of the first limiter 21, thereby increasing the structural strength of the battery tray structure 100.

[0063] Exemplarily, the connection portion 231 is riveted to the base plate 1 .

[0064] Exemplarily, the connection portion 231 is connected to the base plate 1 by pins.

[0065] In some embodiments, Figure 1 As shown, a recessed portion 2321 is formed on the surface of the limiting portion 232 away from the first limiting member 21 , and a protrusion is formed on the bottom wall of the limiting portion 232 on the surface of the limiting portion 232 close to the first limiting member 21 , and the protrusion abuts against the first limiting member 21 .

[0066] In this way, the protrusions can be in contact with the first stopper 21 to limit the forward and backward shaking and rotation of the first stopper 21, reduce the friction generated by the first stopper 21 when limiting the displacement of the battery, extend the service life of the first stopper 21, and thus increase the structural strength of the battery tray structure 100. At the same time, the protrusions can serve as a reinforcement structure to improve the structural strength of the stopper 232.

[0067] It should be noted that the third limiting member 23 may also have other composition forms, which are not limited in the present application and may be selected according to actual conditions.

[0068] In some embodiments, see Figure 1 and Figure 4 , Figure 4 for Figure 2 In the cross-sectional view at AA, the first stopper 21 includes a first connecting plate 211 and a second connecting plate 212. The first connecting plate 211 is arranged opposite to the third stopper 23 and abuts against the third stopper 23. One end of the second connecting plate 212 is connected to the first connecting plate 211, and the second connecting plate 212 is arranged opposite to the bearing surface 11 and spaced apart. The second stopper 22 passes through the second connecting plate 212 and is threadedly connected to the bottom plate 1.

[0069] The first connecting plate 211 and the second flange 13 can limit the battery in the second direction, and the second connecting plate 212 and the bearing surface 11 can limit the battery in the up and down directions. The second limiting member 22 penetrates the second connecting plate 212 and is connected to the bottom plate 1, and the third limiting member 23 is connected to the bottom plate 1 and abuts against the first limiting member 21, which can limit the first limiting member 21 from shaking forward and backward and rotating, reduce the friction generated by the first limiting member 21 when limiting the displacement of the battery, and improve the stability of the battery tray assembly.

[0070] In some embodiments, see Figure 1 The first stopper 21 may further include a third connecting plate 213. One end of the third connecting plate 213 is connected to one end of the second connecting plate 212 away from the first connecting plate 211, and the other end of the third connecting plate 213 extends in a direction away from the bearing surface 11.

[0071] The other end of the third connecting plate 213 extends in a direction away from the carrying surface 11 , and can play a guiding role, making it easier for users to place and take the battery.

[0072] In some embodiments, the third connecting plate 213 may be elastic, which makes it easier for users to place and take the battery.

[0073] In some embodiments, see Figure 1The end of the second flange 13 away from the bearing surface 11 is bent toward the side of the limiting assembly 2 to form a bending portion 131, and the bending portion 131 is opposite to the bearing surface 11 and is spaced apart. In this way, the bending portion 131 can limit the battery in the vertical direction together with the limiting assembly 2 and the bearing surface 11, further improving the stability of the battery tray structure 100.

[0074] In some embodiments, one end of the first flange 12 away from the bearing surface 11 is bent toward the other first flange 12 to form a curved portion, and the curved portion is opposite to and spaced from the bearing surface 11. In this way, the curved portion can limit the battery in the vertical direction together with the limiting assembly 2 and the bearing surface 11, further improving the stability of the battery tray structure 100.

[0075] For example, see Figure 1 A portion of the first flange 12 is formed with a grounding portion 121 at one end away from the bearing surface 11. Along the first direction, the grounding portion 121 is away from the other first flange 12. The grounding portion 121 is formed with a grounding hole 1211, which can be used to assemble the battery harness grounding. A good grounding connection can effectively transmit power and ensure the stability of the power system.

[0076] For example, a portion of the second flange 13 away from the end of the bearing surface 11 may also be formed with a grounding portion, and along the second direction, the grounding portion is away from the limit assembly 2, and the grounding portion may be formed with a grounding hole, which can be used to assemble the battery harness grounding. A good grounding connection can effectively transmit electricity and ensure the stability of the power system.

[0077] In some embodiments, see Figure 1 and Figure 5 , Figure 5 for Figure 2 Cross-sectional view at the middle BB. The bearing surface 11 of the bottom plate 1 is stamped with two second reinforcing ribs 111. The second reinforcing ribs 111 can disperse the force acting on the bottom plate 1 to a wider area, increase the force bearing area of ​​the bottom plate 1, and prevent local stress concentration. By stamping the reinforcing ribs, the bearing capacity of the bottom plate 1 can be improved without increasing the weight of the bottom plate 1, which can save costs and achieve lightweight design.

[0078] like Figure 3 As shown, the vehicle provided in the embodiment of the present application may further include a rear floor rear section 200 , which refers to the rear area of ​​the interior floor of the vehicle, and the battery tray structure 100 is connected to the rear floor rear section 200 .

[0079] It should be noted that the present application does not limit the connection method between the battery tray structure 100 and the rear section 200 of the rear floor, and the specific connection method can be selected according to actual conditions.

[0080] For example, the battery tray structure 100 and the rear floor rear section 200 may be spot-welded. Spot welding has low welding cost and reliable connection strength, which can ensure the stability of the connection between the battery tray structure 100 and the rear floor rear section 200.

[0081] Exemplarily, the battery tray structure 100 and the rear floor rear section 200 may also be connected by rivets.

[0082] In some embodiments, the battery tray structure 100 may further include a partition, and when at least two batteries are placed on the bottom plate 1, a partition is provided between two adjacent batteries. The partition can prevent the batteries from colliding with each other and protect the batteries.

[0083] For example, the partition may be made of rubber, which has an elastic buffering effect and can further prevent damage caused by collision between batteries. The partition may also be made of other elastic materials according to actual needs.

[0084] The battery fixing device of the generator set can also place one or more batteries on the bottom plate 1 according to actual needs. When one battery is placed on the bottom plate 1, there is no need to place a partition on the tray.

[0085] It should be noted that the present application does not limit the material of the battery tray structure 100, and the material can be selected according to actual conditions.

[0086] Exemplarily, the material of the battery tray structure 100 may be aluminum alloy, which has good mechanical properties, corrosion resistance, and high strength, and can ensure the stability of the support and limitation of the battery tray structure 100.

[0087] Exemplarily, the material of the battery tray structure 100 may be high-strength steel, which can provide sufficient strength to support the weight of the battery and ensure the stability of the support and limitation of the battery tray structure 100.

[0088] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
