Description

Technical Field

[0001] The present application relates to the technical field of electric vehicles, and in particular to a battery compartment for an electric vehicle. Background Art

[0002] Existing electric vehicle batteries are usually directly installed at the foot pedal position of the frame. The foot pedal covers the battery box and is fixed to the frame. Since the foot pedal and the frame are often made of the same metal material, the foot pedal is prone to produce abnormal noise due to vibration when in use.

[0003] In this regard, China's patent application number CN202120367993.1 discloses an electric vehicle battery compartment. This solution mainly uses a plastic battery box, which can separate the pedals and the frame, reducing the vibration and noise caused by the rigid contact between the two. At the same time, the battery box protects the battery.

[0004] However, in the process of implementing the technical solutions in the embodiments of the present application, the inventors of the present application discovered that the above technology has at least the following technical problems:

[0005] 1. The battery box fits tightly with the pedal. When the pedal vibrates, the battery box will vibrate along with it. The battery box and the pedal form a cavity, which will amplify the noise.

[0006] 2. The battery does not have shock absorption. During daily driving, the vibration of the battery will affect the reliability of the positive and negative pole connections. Utility Model Content

[0007] In order to make up for the above deficiencies, the present application provides an electric vehicle battery compartment, which aims to improve the problems mentioned in the above background technology.

[0008] An embodiment of the present application provides a battery compartment for an electric vehicle, comprising a compartment body, a pedal, and an elastic frame, wherein the two ends of the elastic frame are fixedly connected to the compartment body and the connecting plastic part respectively, a connecting plastic part is provided on one end of the elastic frame close to the vehicle frame, and the pedal is buckled on the connecting plastic part.

[0009] In a specific embodiment, the elastic frame includes a C-shaped frame and an elastic body. The C-shaped frame is clamped on the electric vehicle frame. The upper end of the elastic body is fixedly connected to the C-shaped frame. The C-shaped frame, the elastic body and the frame are bolted.

[0010] In the above implementation process, the C-shaped frame is clamped on the vehicle frame, and the C-shaped frame, the elastic body and the vehicle frame are strung together and fixed by bolts, which is convenient for assembly.

[0011] In a specific embodiment, the elastic body is a quadrilateral structure, the two sides of the elastic body are arranged in an arc shape, and the waist of the elastic body is tightened with an elastic ring.

[0012] In the above implementation process, when the battery compartment is subjected to vertical vibration, the curved edges on both sides form an elastic buffer. When the impact force is too strong, the curved edges become straight, achieving a rigid connection and playing a limiting role. The curved edges will also pull the elastic ring during deformation. The elastic ring is made of rubber and can consume elastic potential energy.

[0013] In a specific embodiment, the elastic frame further includes a bracket, and the bracket is fixedly connected to the lower end of the elastic body and the warehouse body.

[0014] In the above implementation process, the bracket is used to connect and fix the lower end of the elastic body to the warehouse body. The lower end of the elastic body can be bolted or welded to the warehouse body.

[0015] In a specific embodiment, the connecting plastic part is connected to the C-shaped frame by bolts.

[0016] In the above implementation process, after the four elastic frames are installed on the frame, the connecting plastic parts are fixed to the C-shaped frame by screws to connect the pedals, thereby avoiding the rigid connection between the pedals and the frame and reducing vibration.

[0017] In a specific embodiment, the edges of the connecting plastic part and the bin body are provided with mutually staggered fenders.

[0018] In the above implementation process, the staggered mudguards form an S-shaped channel, and the mud and water on the ground need to pass through the S-shaped channel to enter the warehouse body, thereby achieving a waterproof effect inside the warehouse body and ensuring that the warehouse body can float within a certain range.

[0019] In a specific embodiment, the mouth of the bin body is provided with a detachable pressure strip.

[0020] In a specific embodiment, the pressure strip and the bottom of the bin body are both provided with cushioning pads.

[0021] In the above implementation process, the pressure strip is fixed to the opening of the bin body by screws. The pressure strip can press the battery tightly in the bin body, and the buffer pad is used to alleviate the collision between the battery and the bin body, further reducing noise.

[0022] Compared with the prior art, the beneficial effects of the present application are: connecting plastic parts are used to avoid connection between the pedals and the frame, reducing vibration transmission, and elastic frames are used to achieve elastic connection between the compartment body and the frame, thereby reducing battery vibration and improving wiring reliability. The pedals are not directly connected to the compartment body, reducing the situation where the compartment body is affected by pedal vibration and the vibration noise is amplified.

The elastic frame 30 has two ends fixedly connected to the compartment body 10 and a connecting plastic component 40, respectively. The connecting plastic component 40 is provided on the end of the elastic frame 30 close to the vehicle frame, and the pedal 20 is snapped onto the connecting plastic component 40. The connecting plastic component 40 is used to prevent the pedal 20 from being connected to the vehicle frame, thereby reducing vibration transmission. The elastic frame 30 is used to achieve an elastic connection between the compartment body 10 and the vehicle frame, thereby reducing battery vibration and improving wiring reliability. The pedal 20 is not directly connected to the compartment body 10, thereby reducing the situation where the compartment body 10 is vibrated by the pedal 20 and the vibration noise is amplified.

[0032] See also Figure 1-Figure 5The elastic frame 30 includes a C-shaped frame 31 and an elastic body 32. The C-shaped frame 31 is clamped to the electric vehicle frame.

[0033] See also Figure 1-Figure 5 The elastic body 32 is a quadrilateral with two curved sides. A spring ring 33 is tightened around the waist of the body 32. When the battery compartment is subjected to vertical vibration, the curved sides form an elastic buffer. When the impact force is too strong, the curved sides straighten, achieving a rigid connection and acting as a limiter. The deformation of the curved sides also pulls on the spring ring 33, which is made of rubber and can dissipate elastic potential energy.

[0034] See also Figure 1-Figure 5 The elastic frame 30 also includes a bracket 34, which is fixedly connected to the lower end of the elastic body 32 and the warehouse body 10. The bracket 34 is used to connect and fix the lower end of the elastic body 32 to the warehouse body 10. The lower end of the elastic body 32 can be bolted or welded to the warehouse body 10.

[0035] See also Figure 1-Figure 5 , the connecting plastic part 40 is bolted to the C-shaped frame 31. After the four elastic frames 30 are installed on the frame, the connecting plastic part 40 is fixed to the C-shaped frame 31 by screws to connect the pedal 20, avoiding the rigid connection between the pedal 20 and the frame and reducing vibration.

[0036] See also Figure 1-Figure 5 The edges connecting the plastic part 40 and the silo body 10 are provided with staggered fenders 50. The staggered fenders 50 form an S-shaped channel, through which muddy water on the ground needs to pass before entering the silo body 10, thereby achieving a waterproof effect in the silo body 10 and ensuring that the silo body 10 can float within a certain range.

[0037] See also Figure 1-Figure 5 The opening of the storage body 10 is provided with a removable pressure strip 60. A cushion 70 is provided on both the pressure strip 60 and the bottom of the storage body 10. The pressure strip 60 is fixed to the opening of the storage body 10 with screws. The pressure strip 60 can press the battery tightly into the storage body 10, and the cushion 70 can mitigate the impact between the battery and the storage body 10, further reducing noise.

[0038] The working principle of the electric vehicle battery compartment is as follows: the C-shaped frame 31 is stuck on the frame, and the C-shaped frame 31, the elastic body 32 and the frame are strung together and fixed with bolts. After the four elastic frames 30 are installed on the frame, the connecting plastic part 40 is fixed to the C-shaped frame 31 by screws to connect the pedal 20 to avoid the rigid connection between the pedal 20 and the frame and reduce vibration. The compartment body 10 is placed from top to bottom into the connecting plastic part 40, and the compartment body 10 is fixedly connected with the bracket 34 with screws. The battery is placed in the compartment body 10, and the pressure strip 60 can press the battery tightly in the compartment body 10. The buffer pad 70 is used to alleviate the collision between the battery and the compartment body 10, further reducing noise. Finally, the pedal 20 is buckled on the connecting plastic part 40. When the electric vehicle is driving, it will produce The vertical vibration will cause the mud and water on the ground to splash. When the battery compartment is subjected to vertical vibration, the curved edges on both sides form an elastic buffer, and the staggered mudguards 50 form an S-shaped channel. The mud and water on the ground need to pass through the S-shaped channel to enter the compartment body 10, thereby achieving a waterproof effect in the compartment body 10, and also ensuring that the compartment body 10 can float within a certain range. In summary, the connecting plastic part 40 is used to avoid the connection between the pedal 20 and the frame, thereby reducing vibration transmission, and the elastic frame 30 is used to realize the elastic connection between the compartment body 10 and the frame, thereby reducing the vibration of the battery and improving the reliability of the wiring. The pedal 20 is not directly connected to the compartment body 10, which reduces the situation where the compartment body 10 is vibrated by the pedal 20 and the vibration noise is amplified.
