DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1-Figure 3 , which is the first embodiment of the present invention, and provides a car battery protection device, which includes a fixing unit 1, which is used to be fixed to the chassis of the vehicle to protect the exposed part of the car battery, a buffer unit 2 arranged on the fixing unit 1, which is used to receive external impact and prevent the car battery from being directly impacted, a movable unit 3 arranged on the fixing unit 1, which is used to cooperate with the buffer unit 2 to decompose the impact force when impacted to avoid impact on the car battery, and a buffer spring 4 arranged on the fixing unit 1, which is used to cooperate with the movement of the buffer unit 2 to compress or release before and after the impact, so as to protect the car battery without hindering the normal driving of the car; The fixing unit 1 includes a fixing plate 11, which is used to be fixed on the automobile chassis. The fixing plate 11 is provided with a mounting hole for fixed connection with the automobile chassis, a battery protection component 12 arranged on the fixing plate 11, which is used to wrap the part of the automobile battery exposed from the chassis to prevent sand, gravel and dust from damaging the automobile battery during driving, a front abutment plate 13 arranged on the fixing plate 11, and a rear abutment plate 14 arranged on the fixing plate 11. The front abutment plate 13 and the rear abutment plate 14 cooperate to limit the moving distance of the buffer unit 2.

[0028] The buffer unit 2 includes a movable plate 21 slidably arranged on the fixed plate 11, which is used to drive the buffer unit 2 to move as a whole when impacted, a stopper 22 arranged on the movable plate 21, which is used to receive the impact, and a support block 23 arranged on the movable plate 21, which is used to keep the movable unit 3 stable in the retracted state, and cooperate with the rear abutment plate 14 to squeeze the buffer spring 4 when the buffer unit 2 moves, and when the impact disappears, cooperate with the release of the buffer spring 4 to drive the buffer unit 2 to return to its original position as a whole; One end of the buffer spring 4 is fixedly connected to the support block 23 .

[0029] In summary, first align the battery protection assembly 12 with the car battery so that the fixing plate 11 fits with the car chassis. At this time, fix the fixing plate 11 on the car chassis to complete the installation of the device. When the vehicle passes over a pothole ramp, causing the car chassis to sink, the block 22 is impacted first. At this time, the block 22 is impacted and drives the buffer unit 2 to move backward as a whole. At this time, the support block 23 cooperates with the rear abutment plate 14 to compress the buffer spring 4, and the block 22 moves to drive the movable unit 3 to open. At this time, a part of the impact force received by the block 22 is directly applied to the ground by the movable unit 3, producing an upward effect, which is directly transmitted to the car chassis through the fixing plate 11, driving the car chassis to rise, so that the block 22 leaves the impact object, and cooperates with the car to drive away quickly. At this time, the impact force on the block 22 disappears, and the buffer spring 4 is released, driving the buffer unit 2 to return to its original position as a whole. At this time, the buffer unit 2 moves and drives the movable unit 3 to be retracted, and the device returns to its initial state.

[0030] Example 2, reference Figure 1-Figure 7 , which is the second embodiment of the present invention, and is different from the previous embodiment in that: the automobile battery is prevented from being directly impacted. Compared with the first embodiment, further, a reinforcing plate 111 is provided on the fixed plate 11, which is used to strengthen the connection strength between the fixed plate 11 and the battery protection assembly 12, a sliding groove 112 is provided on the reinforcing plate 111, which is used to adjust the state of the movable unit 3 when the movable plate 21 slides, a through groove 113 is provided on the reinforcing plate 111, which is used to cooperate with the rotation of the movable unit 3 to facilitate the opening and retraction of the movable unit 3, and a sliding groove 114 is provided on the reinforcing plate 111, which is used for the movable plate 21 to slide back and forth on the reinforcing plate 111.

[0031] The battery protection assembly 12 includes a protection cover 121 disposed on the fixing plate 11, which is used to fit the exposed part of the vehicle battery, an outer plate 122 disposed at the bottom of the protection cover 121, which is used to receive the impact from the bottom upward, and a connecting spring 123 disposed between the protection cover 121 and the outer plate 122, which is used to absorb the impact force to achieve a buffering effect; A buffer material is filled between the protective cover 121 and the outer plate 122 to further absorb the impact force, reduce the impact on the protective cover 121, and protect the battery.

[0032] Among them, a slider 211 is provided on the movable plate 21 to cooperate with the slide groove 114. The slider 211 cooperates with the slide groove 114 so that the movable plate 21 can move back and forth on the reinforcing plate 111. A push block 212 is provided on the movable plate 21 to adjust the state of the movable unit 3 in cooperation with the movement of the movable plate 21 and control the opening or retraction of the movable unit 3. An arc surface 213 is provided on the push block 212. Through the setting of the arc surface 213, it is easier to decompose the horizontal force generated when the movable plate 21 moves, reduce the maximum static friction between the push block 212 and the movable unit 3, thereby achieving the purpose of making it easier to adjust the movable unit 3.

[0033] The stopper 22 is provided with a pushing surface 221 and an extruding surface 222, and both the pushing surface 221 and the extruding surface 222 are of inclined design, and the pushing surface 221 and the extruding surface 222 are in the same inclination direction, and the inclination direction is both higher on the left and lower on the right. In this way, when the extruding surface 222 is impacted in the horizontal direction, the horizontal force is decomposed into two directions, horizontal and vertical, through the extruding surface 222, and the horizontal force drives the movable plate 21 to move to the right, and the vertical force is transmitted to the chassis through the fixed plate 11, so that the car has a tendency to move upward, and the scratching of the chassis of the car is reduced. The stopper 22 moves through the pushing surface 221 to decompose the horizontal force into two directions, horizontal and vertical, and generate an upward force on the movable unit 3, making it easier to open the movable unit 3. When the pushing surface 221 contacts the movable unit 3, the push block 212 moves into the sliding groove 112 along with the movable plate 21. The bottom height of the stopper 22 is flush with the bottom height of the outer plate 122 .

[0034] Among them, when the extrusion surface 222 is in a state of being impacted in the front direction, the extrusion surface 222 decomposes the horizontal force into horizontal and vertical component forces. The vertical component force drives the car chassis to move upward, helping the car to drive away quickly.

[0035] The rest of the structure is the same as that of Example 1.

[0036] In summary, when the automobile battery is subjected to a horizontal impact, the extrusion surface 222 is impacted and the horizontal force is decomposed into two directions, horizontal and vertical. The horizontal force drives the movable plate 21 to move to the right. At this time, the support block 23 cooperates with the rear abutment plate 14 to compress the buffer spring 4 to absorb the impact force. The vertical force is transmitted to the chassis through the fixed plate 11, so that the automobile has a tendency to move upward, slowing down the scratching of the automobile chassis and allowing the automobile to quickly leave the road section. At this time, the block 22 drives the push surface 221 to move and further decomposes the horizontal force into two directions, horizontal and vertical. When the push surface 221 contacts the movable unit 3, the push block 212 moves into the sliding groove 112 along with the movable plate 21. At this time, the push surface 221 generates an upward and rightward force on the movable unit 3, making it easier to open the movable unit 3 and further reducing the impact on the automobile battery. If the car battery is impacted upward from the bottom, the outer plate 122 is impacted and the suction is buffered by the connecting spring 123 and the internal filler, and the remaining force is directly transmitted to the car chassis through the protective cover 121 and the fixing plate 11 to prevent the car battery from being directly impacted.

[0037] Example 3, reference Figure 1-Figure 8, which is the second embodiment of the present invention, and is different from the previous embodiment in that: a part of the impact force is reacted to the ground to reduce the force on the device. Compared with embodiment 1, further, the movable unit 3 includes a connecting plate 31 arranged on the protective cover 121, which plays a role of connection and support, a movable wheel set 32 ​​arranged on the connecting plate 31, which is used to rotate when subjected to friction, a connecting shaft 33 arranged on the connecting plate 31 and connected to the protective cover 121 for the axis of rotation of the connecting plate 31, a pushing rod 34 arranged on the connecting plate 31, which is used to drive the connecting plate 31 to rotate around the connecting shaft 33 as the axis when squeezed by the pushing surface 221, and an abutting rod 35 arranged on the connecting plate 31, which is used to cooperate with the support block 23 to support the connecting plate 31. When the connecting plate 31 is in a retracted state, the abutting rod 35 abuts against the support block 23.

[0038] The push block 212 is in sliding contact with the connecting plate 31 . When the push block 212 moves into the sliding groove 112 , the push block 212 is located at the right side of the connecting shaft 33 .

[0039] The connecting plate 31 abuts against the bottom of the reinforcing plate 111 to cooperate with the supporting block 23 and the connecting shaft 33 to fix the state of the connecting plate 31 to prevent shaking and abnormal noise during driving.

[0040] Among them, when the block 22 is in a state of being impacted in the front direction, the extrusion surface 222 decomposes the horizontal force into horizontal and vertical forces, and the horizontal force continues to drive the pushing surface 221 to move. When the pushing surface 221 contacts the pushing rod 34, the horizontal force is again decomposed into horizontal and vertical forces, and the vertical force drives the pushing rod 34 to move upward, quickly deflecting the connecting plate 31, so that the movable wheel group 32 quickly contacts the road surface to reduce the impact force.

[0041] The distance from the connecting shaft 33 to the pushing rod 34 is much smaller than the distance to the abutting rod 35 , so that by moving a smaller distance to the pushing rod 34 , the abutting rod 35 can be moved a larger distance and quickly abut against the road surface.

[0042] The rest of the structure is the same as that of Example 2.

[0043] In summary, when the stopper 22 drives the support block 23 to move to the right through the movable plate 21, the slider 211 begins to enter the sliding groove 112, and the support block 23 begins to leave the abutment rod 35. When the pushing surface 221 contacts the pushing rod 34, the slider 211 completely enters the sliding groove 112, and the support block 23 completely leaves the abutment rod 35. At this time, under the action of the connecting shaft 33, the center of the connecting plate 31 is to the right, and the connecting plate 31 has a tendency to rotate to the right. At this time, the support block 23 cooperates with the rear abutment plate 14 to compress the buffer spring 4. At this time, the extrusion surface 222 pushes the pushing rod 34, driving the connecting plate 31 to rotate to the right, so that the movable wheel group 32 contacts the ground, generating a supporting force for the fixed plate 11, and assisting the car to quickly pass through the potholes. When the car leaves the bumpy road, the buffer spring 4 is released, and the buffer unit 2 is pushed to the left as a whole through the support block 23. At this time, the push block 212 generates a leftward thrust on the connecting plate 31 through the arc surface 213, driving the connecting plate 31 to rotate leftward with the connecting shaft 33 as the axis, and driving the abutment rod 35 to move upward. At this time, the abutment rod 35 moves to the top of the bottom of the support block 23 and abuts against the support block 23. At this time, the connecting plate 31 abuts against the reinforcing plate 111. At this time, under the action of the buffer spring 4, the stop block 22 abuts against the front abutment plate 13, and the device returns to its initial state.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
