Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, and in particular to an electric vehicle frame that facilitates battery mounting. Background Technology

[0002] Electric vehicles, also known as electric-driven vehicles, are divided into AC electric vehicles and DC electric vehicles. Generally speaking, electric vehicles use batteries as their energy source and convert electrical energy into mechanical energy through components such as controllers and motors. The speed of a vehicle is changed by controlling the amount of current. The frame of an electric vehicle is the core part that supports its movement, and the choice of battery is also very important. A good battery can greatly reduce the user's later use and maintenance costs. The battery is usually installed inside a battery box on the frame.

[0003] Currently, when installing batteries for electric vehicles, multiple bolts and screwdrivers are typically used to secure the battery to the bracket inside the battery box, which then uses a protective cover to protect and secure the battery. When there are many customers in the electric vehicle repair shop, replacing the battery takes a long time, which increases the fatigue of the repair personnel. Utility Model Content

[0004] To address the aforementioned issues of using multiple bolts and screwdrivers to secure the battery in the battery box with a bracket, and using a protective cover to protect and secure the battery in electric vehicles, which can lead to lengthy battery replacement times and increased fatigue for repair personnel when there are many customers in the electric vehicle repair shop, this invention provides an electric vehicle frame that facilitates battery securing.

[0005] This utility model provides an electric vehicle frame that facilitates battery mounting, employing the following technical solution: An electric vehicle frame for convenient battery fixing includes a frame body, a placement cavity is formed on the lower side of the top surface of the frame body, a fixing frame is slidably disposed inside the placement cavity, a fixing cover is slidably disposed on the upper side of the inner wall of the placement cavity, a cross groove is formed at the bottom of the fixing cover, and a limiting component for fixing the battery is slidably disposed inside the cross groove. Two circular grooves are opened on both the front and rear sides of the inner wall of the fixed frame. Springs are fixedly installed inside each of the four circular grooves. Two springs are arranged in pairs, and clamping plates for clamping the side of the battery are fixedly installed at one end of each pair.

[0006] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, the limiting component includes a T-shaped plate, which is slidably disposed inside the vertical groove of the cross groove. A first compression spring is fixedly disposed on the top of the vertical plate of the T-shaped plate, and the top end of the first compression spring is fixedly connected to the upper side of the inner wall of the vertical groove of the cross groove. A cross limiting plate is fixedly disposed on the bottom of the vertical plate of the T-shaped plate, and the length of the cross limiting plate is equal to the length of the inner wall of the cross groove. The bottom of the cross limiting plate contacts the top of the clamping plate.

[0007] The above technical solution facilitates the compression of the first compression spring when the fixed cover moves the cross-shaped limiting plate downward and contacts the battery. The pressure from the fixed cover and the contact with the battery compress the first compression spring, thereby clamping the upper side of the battery through the stress generated by the deformation of the first compression spring.

[0008] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, long grooves are fixedly provided on both the front and rear sides of the bottom of the fixing cover, a movable strip is slidably provided on the side of the inner wall of the long groove, a second compression spring is fixedly provided on the side of the movable strip, one end of the second compression spring is fixedly connected to the side of the inner wall of the long groove, and two rectangular grooves that cooperate with the movable strip are opened on the lower side of the top surface of the frame body.

[0009] The above technical solution allows the two moving bars to move simultaneously toward the center through the two long slots, compressing the second compression spring and causing the insert block to move into the interior of the fixed slot.

[0010] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, an insert block is fixedly provided on the side of the movable strip near the second compression spring, and a rectangular frame is fixedly provided on the side of the clamping plate near the spring. One side of the rectangular frame extends to the outside of the fixed frame. Fixing grooves are provided inside both rectangular frames. Movable grooves that cooperate with the rectangular frames are provided on the front and rear sides of the inner wall of the placement cavity. The side of the movable strip slides with the side of the inner wall of the rectangular frame, and the side of the insert block slides with the side of the inner wall of the fixing groove.

[0011] The above technical solution facilitates the fixing of the cover to the upper side of the fixing frame after the insert block moves into the fixing slot.

[0012] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, the side of the clamping plate is slidably connected to the side of the inner wall of the fixing frame, and silicone sheets are fixedly provided on the opposite side of the two clamping plates and the bottom of the cross limiting plate.

[0013] The above technical solution enables the silicone sheet to have excellent insulation properties, while also buffering the impact of vibration on the internal battery of the electric vehicle during movement.

[0014] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, hexagonal socket head cap screws are rotatably provided on both the front and rear sides of the frame body, and the ends of the hexagonal socket head cap screws abut against the sides of the moving strip.

[0015] The above technical solution allows the two moving strips to be moved towards the center using hexagonal socket head cap screws, while simultaneously fixing the fixing frame and fixing cover to the vehicle frame body.

[0016] Optionally, in the above-mentioned electric vehicle frame for convenient battery fixing, the shape of the inner wall of the long groove and the shape of the inner wall of the moving strip are both T-shaped.

[0017] The above technical solution enables the T-shaped moving strip to move horizontally and stably inside the T-shaped long groove on the inner wall, without moving out of the long groove.

[0018] In summary, this utility model has at least one of the following beneficial effects: by placing the fixing frame into the placement cavity and moving the rectangular frame into the moving slot to limit the fixing frame, after the battery is placed into the fixing frame, the fixing cover is moved to the upper side of the placement cavity, and the moving strip is inserted into the rectangular slot. Then, the internal hex bolts are moved to abut against the side of the moving strip, so that the two inserts are moved into the fixing slot, thereby fixing the battery on the electric vehicle, thus reducing the fatigue of maintenance personnel.

[0019] When the hex bolts move out of the frame body, the resistance to the moving strips is released, allowing the two moving strips to move out of the fixing slot via the second compression spring. Then, the fixing cover moves upward via the first compression spring, causing the fixing cover to move out of the placement cavity and rectangular slot via the cross limit plate, thereby releasing the battery from the fixing frame. The battery can then be removed from the fixing frame for quick inspection and repair. Attached Figure Description

The length of the cross limiting plate 903 is equal to the length of the inner wall of the cross groove 5. The bottom of the cross limiting plate 903 contacts the top of the clamping plate 8. When the fixing cover 4 moves the cross limiting plate 903 down to contact the battery, the first compression spring 902 is compressed by the downward pressure of the fixing cover 4 and the contact with the battery. The stress generated by the deformation of the first compression spring 902 clamps the upper side of the battery.

[0025] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 Both the front and rear sides of the bottom of the fixed cover 4 are fixedly provided with long grooves 401.

Two rectangular grooves 404 that cooperate with the moving strips 402 are opened on the lower side of the top surface of the frame body 1. The two moving strips 402 can move towards the middle at the same time through the two long grooves 401 and compress the second compression spring 403, so that the insert 405 moves into the interior of the fixed groove 802.

[0026] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A block 405 is fixedly installed on the side of the moving bar 402 near the second compression spring 403. A rectangular frame 801 is fixedly installed on the side of the clamping plate 8 near the spring 7. One side of the rectangular frame 801 extends to the outside of the fixed frame 3. Fixed grooves 802 are opened inside both rectangular frames 801. Moving grooves 201 that cooperate with the rectangular frames 801 are opened on the front and rear sides of the inner wall of the placement cavity 2. The side of the moving bar 402 slides with the side of the inner wall of the rectangular frame 801. The side of the block 405 slides with the side of the inner wall of the fixed groove 802. When the block 405 moves into the inside of the fixed groove 802, the fixed cover 4 can be fixed on the upper side of the fixed frame 3.

[0027] See the attached diagram in the instruction manual. Figure 5 , Figure 6 The side of the clamping plate 8 is slidably connected to the side of the inner wall of the fixed frame 3. The opposite side of the two clamping plates 8 and the bottom of the cross limit plate 903 are both fixedly provided with silicone sheets 904. The silicone sheets 904 have excellent insulation effect and can also buffer the impact of vibration on the internal battery of the electric vehicle when it moves.

[0028] See the attached diagram in the instruction manual. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Both the front and rear sides of the frame body 1 are rotatably equipped with hex bolts 101. The ends of the hex bolts 101 abut against the sides of the moving strips 402. The two moving strips 402 can be moved towards the middle by the hex bolts 101, and the fixing frame 3 and the fixing cover 4 can be fixed to the frame body 1.

[0029] See the attached diagram in the instruction manual. Figure 4 , Figure 5The inner wall of the long groove 401 and the inner wall of the moving strip 402 are both T-shaped. The T-shaped moving strip 402 can move horizontally and stably inside the long groove 401 with its inner wall in the T shape, and will not move out of the long groove 401.

[0030] Working principle: When using this convenient battery-fixing electric vehicle frame, to fix the battery, first, the fixing frame 3 is placed inside the placement cavity 2, and the two rectangular frames 801 are moved into the two moving slots 201 to limit the fixing frame 3. After the battery is placed inside the fixing frame 3, the fixing cover 4 is moved to the upper side of the inner wall of the placement cavity 2, and the two moving strips 402 are inserted into the two rectangular slots 404 and moved into the rectangular frames 801. Then, the fixing frame 3 is pressed downwards. The compression releases the cross-shaped limiting plate 903 and its bottom silicone sheet 904 from the upper side of the battery. At the same time, the cross-shaped limiting plate 903 is subjected to the downward pressure of the fixing cover 4 and the battery is limited, causing the first compression spring 902 to be compressed. The stress of the first compression spring 902 fixes the battery. Then, the two internal hex bolts 101 are moved to abut against the side of the moving strip 402, causing the two inserts 405 to move to contact the inside of the fixing groove 802. The battery can be quickly fixed to the upper side of the electric vehicle, thereby reducing the fatigue of maintenance personnel. By moving the hex bolt 101 out of the frame body 1, the resistance to the moving strip 402 is released, and the two moving strips 402 are reset to the front and rear sides by the rebound force of the second compression spring 403. The insert block 405 is moved out of the fixed groove 802. Then, the fixed cover 4 moves upward by the rebound force of the first compression spring 902, so that the fixed cover 4 can drive the cross limit plate 903 at its bottom to move out from the inner wall of the placement cavity 2 and the rectangular groove 404. This quickly releases the battery from the fixed frame 3, allowing the battery to be removed for quick inspection and maintenance.

[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
