Description

Technical Field

[0001] The present invention relates to the technical field related to automobile battery shock absorption, and in particular to a shock absorption device for a new energy vehicle battery pack. Background Art

[0002] New energy vehicles (NEVs) use unconventional fuels as their power source (or use conventional fuels with new onboard power units), integrating advanced technologies in vehicle power control and drive to create vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles, pure electric vehicles, fuel cell electric vehicles, and other new energy vehicles.

[0003] As an important component of new energy batteries, automotive batteries must be protected from damage. When electric vehicles are driving dynamically, the uneven road surface will cause the vehicle to vibrate and impact. These vibrations and impacts will be transmitted to the battery pack through the vehicle chassis. If the buffer structure is improperly designed or the material selection is unreasonable, the battery pack may be damaged.

[0004] The patent document "A battery box shock absorber for new energy vehicles" with Chinese application number CN202022087253.0 discloses a battery box shock absorber for new energy vehicles, which is provided with a spring, a shock-absorbing pad, a first shock-absorbing pad, a second shock-absorbing pad and a sponge pad. When using the battery box shock absorber for new energy vehicles, through the arrangement of the spring, the shock-absorbing pad, the first shock-absorbing pad, the second shock-absorbing pad and the sponge pad, the dual shock-absorbing effect of the spring and the shock-absorbing pad enhances the shock-absorbing effect of the device. At the same time, the first shock-absorbing pad and the second shock-absorbing pad can protect the left and right sides of the battery box, and the sponge pad can protect the upper side of the battery box when the fixed frame drives the battery box to move up and down, so that the shock-absorbing effect of the device is more comprehensive, so that the battery box can be more comprehensively protected. However, the above patent still has the following shortcomings. Although the shock-absorbing box body and several springs and shock-absorbing pads can achieve a shock-absorbing effect and reduce the impact of vibration on the battery box when the car is driving, the added shock-absorbing related equipment will affect the heat dissipation of the battery pack. The battery pack cannot dissipate heat in time during use, which will also bring safety hazards. Therefore, it is necessary to design a shock-absorbing device for the battery pack of new energy vehicles. Summary of the Invention

[0019] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0020] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0021] like Figure 1-7 As shown, a shock absorbing device for a new energy vehicle battery pack includes: a square hollow mounting shell 1, a battery shell 2 whose top and bottom respectively slide in contact with the top and bottom of the inner side of the mounting shell 1, and a plurality of shock absorbing components respectively arranged on the corresponding inner side walls of the mounting shell 1 and in sliding contact with the corresponding outer side walls of the battery shell 2; Each outer side wall of the battery shell 2 is arranged parallel to the corresponding inner side wall of the mounting shell 1. The shock absorbing assembly includes a horizontal piston cylinder 3 that is detachably assembled on the inner side wall of the mounting shell 1 through a mounting mechanism, a piston 4 that is slidably assembled in the piston cylinder 3, and an elastic damping mechanism that is fixedly connected to the piston 4 and slides through the end of the piston cylinder 3 to fit in and slide with the outer wall of the battery shell 2. The portion of the piston cylinder 3 away from the battery shell 2 is provided with a pair of connection ports, one of which is connected to a one-way air intake mechanism, and the other connection port is connected to the interior of the battery shell 2 through a one-way exhaust mechanism. The battery shell 2 is provided with a plurality of heat dissipation holes 5.

[0022] In the above technical solution, when the battery shell 2 shakes during driving, when the battery shell 2 moves close to the inner side wall of the corresponding mounting shell 1, it will squeeze the corresponding elastic resistance mechanism, and the elastic damping mechanism can play a shock-absorbing role. Because the mounting shell 1 is square, when the battery shell 2 shakes, it will drive a pair of elastic damping mechanisms in the relative shock-absorbing assembly to extend and shorten respectively. The elastic damping mechanism can reduce the speed when extending and shortening, and play a double shock-absorbing role to prevent the battery pack in the battery shell 2 from being damaged by vibration; when the distance between the other side walls of the battery shell 2 and the corresponding side walls of the mounting shell 1 remains unchanged, the outer wall of the battery shell 2 will slide with the corresponding elastic damping mechanism; The pair of elastic damping mechanisms disposed in an opposing state exert completely opposite forces on the battery case 2. Therefore, the pair of elastic damping mechanisms are both in a semi-compressed state and can be further compressed or further extended. The elastic damping mechanisms themselves have the function of returning to their original position. Therefore, after the battery case 2 slides to compress and extend the corresponding pair of elastic damping mechanisms, they will also be damped when returning to their original position, reducing the speed of returning to their original position. The battery pack generates heat during use, which can be dissipated through the heat dissipation holes 5. When the elastic damping mechanism is compressed, the piston 4 is driven to slide in the piston cylinder 3 near the side wall of the mounting shell 1, thereby pushing the air in the piston cylinder 3 into the battery shell 2 through the one-way exhaust mechanism. The air entering the battery shell 2 will squeeze the original hot air out of the heat dissipation holes 5, thereby playing a role in cooling the battery pack inside the battery shell 2. When the elastic damping mechanism returns to its original position, the piston 4 slides in the piston cylinder 3 away from the corresponding side wall of the mounting shell 1, and air is added into the piston cylinder 3 through the one-way air intake mechanism, which can achieve shock absorption while also dissipating heat to the battery pack inside the battery shell 2.

[0023] In a preferred embodiment of the present invention, the elastic damping mechanism includes a damping telescopic rod 6 coaxially assembled inside the piston cylinder 3 and fixedly connected at both ends to the piston 4 and the end of the piston cylinder 3 away from the battery shell 2, a spring 7 sleeved on the damping telescopic rod 6 and with both ends respectively in conflict with the piston 4 and the end of the piston cylinder 3 away from the battery shell 2, a connecting rod 8 fixedly connected to the piston 4 and coaxially sliding through the end of the piston cylinder 3 close to the battery shell 2, and a support plate 9 fixedly connected to the connecting rod 8 and in sliding contact with the outer wall of the battery shell 2; A horizontal slide bar 29 is protruding from the support plate 9 , and a horizontal first slide groove 30 matching the slide bar 29 is recessed on the outer wall of the battery housing 2 .

[0024] In the above technical solution, the damping telescopic rod 6 is an existing mature technology, and its structure and working principle are not described in this article; When the distance between the mounting shell 1 and the battery shell 2 remains unchanged, the battery shell 2 will slide against the support plate 9, and the slide bar 29 will slide relative to the inner wall of the first slide groove 30; when the battery shell 2 pushes the elastic damping mechanism to compress, the connecting rod 8 pushes the piston 4 to slide near the inner wall of the mounting shell 1 in the piston cylinder 3, and at the same time pushes the damping telescopic rod 6 to compress, and the spring 7 is further compressed; when the elastic damping mechanism returns to its original position, the spring 7 will push the piston 4 to slide on the inner wall of the original mounting shell 1 in the piston cylinder 3, driving the damping telescopic rod 6 to restore its original length.

[0025] In a preferred embodiment of the present invention, the mounting housing 1 comprises a housing and a cover assembled on the top of the housing; A vertical mounting groove 10 with an open top is recessed on the inner side wall of the shell, and the end of the piston cylinder 3 away from the battery shell 2 is assembled at the bottom of the mounting groove 10. The mounting mechanism includes a mounting block 11 that can be detachably assembled in the mounting groove 10 and can be pressed on the piston cylinder 3.

[0026] In the above technical solution, when the wearing parts need to be replaced, the mounting block 11 is removed from the mounting groove 10, and then the connecting rod 8 is separated from the support plate 9, so that the part where the elastic damping mechanism is located can be disassembled and replaced, that is, the piston cylinder 3, the piston 4 and the elastic damping mechanism as a whole can be replaced.

[0027] In a preferred embodiment of the present invention, a clamping strip portion 12 is fixedly protruded on the outer wall of the piston cylinder 3, a first clamping groove matching the clamping strip portion 12 is recessed on the mounting block 11, a first clamping block portion 13 is protruded from the end of the clamping strip portion 12 away from the battery shell 2, and a second clamping groove matching the first clamping block portion 13 is recessed on the side wall of the first clamping groove.

[0028] In the above technical solution, the mounting block 11 can fix one end of the piston cylinder 3 at the bottom of the mounting groove 10, the first clamping groove can prevent the piston cylinder 3 from rotating, and the protruding first clamping block portion 13 can prevent the piston cylinder 3 from slipping from the bottom of the mounting groove 10 and the mounting block 11, thereby improving the installation stability.

[0029] In a preferred embodiment of the present invention, two opposite side walls of the mounting groove 10 are each provided with a vertical third slot 14 with an open top, and the mounting block 11 is provided with a protruding second block portion 15 that can vertically slide and engage in the third slot 14; A fourth slot 16 is recessed on one of the side walls of the mounting slot 10 . The mounting mechanism further includes a positioning arm 17 that is slidably assembled on the mounting block 11 along its length and can pass through the mounting block 11 and insert into the fourth slot 16 .

[0030] In the above technical solution, the mounting block 11 is inserted into the mounting groove 10 in the vertical direction, and the corresponding second block portion 15 is slidably inserted into the third slot 14, restricting the mounting block 11 from sliding only in the vertical direction; the positioning arm 17 is then inserted into the corresponding fourth slot 16, restricting the movement of the mounting block 11 in the vertical direction, thereby fixing the mounting block 11.

[0031] In a preferred embodiment of the present invention, a vertical threaded hole 18 is provided on the top of the mounting block 11, and a horizontal second slide groove communicating with the threaded hole 18 is provided on the side wall of the mounting block 11, and the positioning arm 17 is slidably assembled in the second slide groove; The mounting mechanism further includes a first magnet 19 mounted in the fourth slot 16, a second magnet 20 mounted on the end of the positioning arm 17 close to the fourth slot 16 and repelling the first magnet 19, and a first bolt 21 threadedly mounted on the threaded hole 18. The end of the first bolt 21 is in a conical shape, and the end of the positioning arm 17 away from the second magnet 20 is in an oblique wedge shape that contacts the end of the first bolt 21 .

[0032] In the above technical solution, when assembling, the first bolt 21 is tightened, and the conical end of the first bolt 21 presses the oblique wedge-shaped end of the positioning clamp arm 17, pushing the end of the positioning clamp arm 17 away from the first bolt 21 and clamping it into the fourth clamping groove 16; During disassembly, the first bolt 21 is loosened, and the first magnet 19 and the second magnet 20 are arranged in a repulsive state. Therefore, the repulsive force between the two can push the positioning arm 17 out of the fourth slot 16, thereby removing the mounting block 11. The operation is simple and quick.

[0033] In a preferred embodiment of the present invention, the connecting rod 8 includes a first branch rod 22 fixedly connected to the piston 4 and sliding through the piston cylinder 3, and a second branch rod 24 connected to the first branch rod 22 in the same length direction by at least one second bolt 23, and the second branch rod 24 is fixedly connected to the support plate 9.

[0034] In the above technical solution, when disassembling the relevant parts of the elastic damping mechanism, the mounting block 11 is disassembled, and then the second bolt 23 is loosened and removed, so that the first branch rod 22 and the second branch rod 24 are separated, and the relevant parts of the elastic damping mechanism can be taken out upward and replaced, which is simple and convenient to operate; the buffer part can be disassembled and assembled, so that when the buffer part is damaged, the part used for buffering can be easily replaced.

[0035] In a preferred embodiment of the present invention, the one-way exhaust mechanism includes a hose 25 whose two ends are respectively connected to the corresponding connection ports and the interior of the battery shell 2 and a one-way exhaust valve 26 assembled on the hose 25.

[0036] In the above technical solution, since the battery shell 2 shakes in the mounting shell 1, the air in the piston cylinder 3 is input into the battery shell 2 through the hose 25. The one-way exhaust valve 26 is an existing mature technology and is a type of check valve.

[0037] In a preferred embodiment of the present invention, the one-way air intake mechanism includes an air intake pipe 27 mounted on the corresponding connection port and a one-way air intake valve 28 mounted on the air intake pipe 27 .

[0038] In the above technical solution, air can be added into the piston cylinder 3 through the one-way air intake valve 28 when the piston 4 slides away from the inner wall of the mounting shell 1. The one-way air intake valve 28 is an existing mature technology and is a type of check valve.

[0039] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0040] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction.
