Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, in particular to a vehicle battery fixing structure. Background Art
[0002] The vehicle battery plays a vital role in vehicle operation. Its main functions include the following aspects:
[0003] Starting the engine: As the initial energy source of the vehicle, the battery provides the necessary electrical energy for starting the engine, ensuring that the vehicle can start smoothly.

[0049] See also Figure 1 The present embodiment provides a vehicle battery fixing structure, the vehicle comprises a vehicle body 1, the vehicle body 1 is provided with a rear wheel cover 11, the vehicle body 1 is provided with a rear wheel cover rear side space 12 at the rear side of the rear wheel cover 11, and the vehicle battery fixing structure comprises:
[0050] The fixing assembly 2 disassembles the battery 3 in the space 12 at the rear side of the rear wheel housing.
[0051] The rear wheel cover 11 refers to a sheet metal or plastic part installed on the outside of the rear wheel of the vehicle. The rear side space 12 of the rear wheel cover refers to the space inside the vehicle body that faces the rear of the vehicle. This space is usually behind the rear wheel cover 11, that is, the gap between the side of the vehicle body and the chassis, and the surface is relatively flat. In some vehicle designs, this space may not be fully utilized, and the vehicle battery fixing structure mentioned in the claims of this patent utilizes this space.
[0052] Different from the prior art, the above technical solution provides a vehicle battery fixing structure, which reasonably utilizes the space 12 behind the rear wheel cover without changing the original vehicle layout, reduces the impact on other important structural areas, and reduces the encroachment of the battery 3 on the vehicle layout space requirement. By placing the battery 3 on the rear side of the rear wheel cover 11 through the fixing component 2, with the help of the physical blocking effect of the rear wheel cover 11, it effectively prevents the battery 3 from flying out uncontrollably during a vehicle collision, thereby improving the vehicle safety.
[0053] See also Figures 2 to 5 In this embodiment, the fixing component 2 includes:
[0054] A lower fixing assembly 22, which is connected to the vehicle body 1 and is located in the rear space 12 of the rear wheel housing; and
[0055] An upper fixing assembly 21, which is detachably connected to the lower fixing assembly 22 and is located above the lower fixing assembly 22;
[0056] A limiting space for accommodating the battery 3 is formed between the upper fixing assembly 21 and the lower fixing assembly 22, so as to ensure that the battery 3 is effectively fixed in the up and down directions after installation.
[0057] The design of the upper and lower double-layer fixing components provides a more stable and safe solution for fixing the battery 3. The detachable connection design between the upper fixing component 21 and the lower fixing component 22 simplifies the installation, disassembly and maintenance process of the battery 3 and significantly improves the maintenance efficiency.
[0058] See also Figure 4 and Figure 5In this embodiment, the limiting space includes an upper limiting groove 223 and a lower limiting groove 214. The upper fixing component 21 is provided with an upper limiting groove 223 for accommodating the upper part of the battery 3, and the upper limiting groove 223 is used to prevent the battery 3 from moving. The lower fixing component 22 is provided with a lower limiting groove 214 for accommodating the lower part of the battery 3, and the lower limiting groove 214 is used to prevent the battery 3 from moving. When the battery 3 is placed in the rear side space 12 of the rear wheel housing, the lower part of the battery 3 will be embedded in the lower limiting groove 214, thereby preventing the battery 3 from moving in the horizontal direction (a certain installation tolerance is allowed), and the upper part of the battery 3 will be embedded in the upper limiting groove 223, thereby preventing the battery 3 from moving upward and in the horizontal direction (a certain installation tolerance is allowed). The design of the upper limiting groove 223 and the lower limiting groove 214 ensures that the six degrees of freedom of the battery 3 in the three-dimensional space are all limited, that is, the three directions of front and back, left and right, and up and down are all effectively constrained, thereby achieving the purpose of fixing the battery 3.
[0059] See also Figure 2 and Figure 4 In this embodiment, the lower fixing assembly 22 includes a tray 211, a bracket 212 and a connecting piece 213. The tray 211 is connected to the vehicle body 1 and is located in the space 12 behind the rear wheel housing. The tray 211 is provided with a lower limit groove 214 for accommodating the battery 3. The lower part of the bracket 212 is connected to the tray 211. There are two brackets 212, which are located on the left and right sides of the battery 3. Each bracket 212 is connected to a connecting piece 213, that is, one bracket 212 corresponds to one connecting piece 213, and the connecting piece 213 is detachably connected to the upper fixing assembly 21. The left and right end structures of the pressure plate 222 at the contact point with the battery 3 sink, which plays a role in limiting the movement in the horizontal left and right directions.
[0060] Preferably, the tray 211 is welded to the vehicle body 1 , and the lower portion of the bracket 212 is welded to the tray 211 .
[0061] See also Figure 2 and Figure 4 In this embodiment, the bracket 212 is provided with a lifting ear 215, and the connecting member 213 is a hook, one end of the hook is a hook portion, the hook portion is hooked into the lifting ear 215, and the other end of the hook is detachably connected to the upper fixing component 21. The bracket 212 and the upper fixing component 21 are adjustablely connected by the cooperation of the lifting ear 215 and the hook. The cooperation between the lifting ear 215 and the hook enables the entire structure to have a certain degree of flexibility while retaining a certain degree of rigidity. The detachable connection design of the hook and the upper fixing component 21 embodies the characteristics of modularization and quick disassembly and assembly, which is conducive to improving the efficiency of maintenance and replacement.
[0062] See also Figure 4In this embodiment, the bracket 212 is provided with a plurality of lifting ears 215 in the vertical direction. The plurality of lifting ears 215 can be hung at the most suitable height according to the actual height distribution of the battery 3, so as to achieve a more balanced stress state. During installation, fine adjustment can be made according to the specific position and posture of the battery 3 to ensure the stability of the battery 3 after installation, which is conducive to the normal use and maintenance of the battery.
[0063] See also Figure 2 and Figure 4 In this embodiment, the other end of the hook is provided with a thread (processing nominal diameter M6 or M8, adjusted based on demand), the upper fixing assembly 21 includes a nut 221 and a pressure plate 222, the nut 221 is threadedly connected to the other end of the hook, the pressure plate 222 is provided with a slot for the other end of the hook to pass through, and the pressure plate 222 contacts the upper part of the battery 3 and is used to press down the upper part of the battery 3. The nut 221 and the hook are engaged with each other through the thread to achieve a tight connection. The relative position between the hook and the pressure plate 222 is adjusted and fixed by tightening the nut 221, thereby applying a stable downward pressure to the battery 3. The pressure plate 222 is designed to contact and press the upper part of the battery 3, and can evenly transmit pressure to ensure that the battery 3 will not move upward due to vibration and other reasons. At the same time, it is also conducive to maintaining good contact between the battery 3 and the circuit to prevent loose connection.
[0064] In some embodiments, the detachable connection between the connector and the pressure plate may be a snap-fit connection.
[0065] See also Figure 2 and Figure 4 In this embodiment, the pressing plate 222 is provided with an upper limit groove 223 for accommodating the battery 3. The upper limit groove 223 of the pressing plate 222 is used to fix the battery 3 by pressing down, and further restricts the lateral and longitudinal movement of the battery 3 by physical limiting. This groove design can ensure that the battery 3 is in a preset precise position after installation, and prevent the battery 3 from sliding or deflecting on the upper part due to vibration and other reasons during the driving of the vehicle.
[0066] See also Figure 2 and Figure 4 In this embodiment, the pressure plate 222 is bent to form an upper limit groove 223, and the side walls of the limit groove limit the upper part of the battery 3. The pressure plate 222 is arranged along the width direction of the vehicle, and the side walls of the limit groove are left and right side walls, which can prevent the battery 3 from moving along the width of the vehicle ( Figure 3 Of course, in some embodiments, the upper limit slot 223 can prevent the battery 3 from moving along the length (left and right) of the vehicle. Figure 3 Movement in the forward and backward directions.
[0067] See also Figure 4 and Figure 5 In this embodiment, the upper surface of the tray 211 protrudes upward with a profile step, and the four side walls of the profile step form a lower limit groove 214. A gap that satisfies the installation tolerance is reserved between the limit groove and the battery 3 to play a limiting role. When the battery 3 is placed, its lower part will be embedded in the groove surrounded by four sides formed by the profile step protruding from the upper surface of the tray 211, thereby achieving accurate limit and support for the bottom of the battery 3.
[0068] In some embodiments, the fixing component may be a fixing cover, which fixes the battery in the space behind the rear wheel housing, and the fixing cover and the vehicle body may be detachable by means of threaded connection, snap-on connection, etc.
[0069] In this embodiment, the vehicle is an electric vehicle. An electric vehicle, also known as an electric drive vehicle, is a means of transportation that uses electric energy as the main driving force. Its working principle is to store electric energy through a battery, and then control the current to flow to the motor through a controller, thereby converting the electric energy into mechanical energy to drive the vehicle. In some embodiments, the vehicle is a fuel vehicle or a hybrid vehicle.
[0070] This application has the following beneficial effects:
[0071] (1) The battery 3 is placed behind the wheel arch, which frees up space in the engine compartment of the vehicle, making the layout of the front compartment more reasonable and expandable. At the same time, the vertical space of the spare tire slot is basically not occupied here, reducing the encroachment of the battery 3 on the space requirements of the vehicle layout and architecture expansion, and making the vehicle integration effect more obvious. The layout space of the front compartment and the rear floor luggage box area is optimized, and the vehicle design is more flexible and reasonable.
[0072] (2) The battery 3 is placed at the rear of the wheel arch. Even if the actual collision force is large and exceeds the upper limit of the simulation, it can be blocked by the structure of the wheel arch directly in front, thus avoiding the safety problem of the battery 3 flying out uncontrollably after the collision.
[0073] (3) Reduce structural weight and costs based on previous solutions.
[0074] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
