[0025] See also Figure 3-Figure 7 In the embodiment of the present invention, the bearing mechanism 2 includes a carrier plate 21, and rectangular through grooves are symmetrically provided on the carrier plate 21.

[0026] The slide plate 23 is slidably connected to the rectangular through slot, and the buffer spring group is composed of two buffer springs, which are respectively located at the front and rear sides of the slide plate 23. The arrangement of the buffer spring group enables the tray 24 to perform lateral buffering and shock absorption protection on the battery body loaded thereon, thereby improving the anti-collision effect on the battery body.

[0027] The longitudinal buffer component is composed of a shock absorber body 3 and a secondary shock absorbing mechanism 4. There are four shock absorber bodies 3, which are respectively arranged at the four corners of the bottom of the carrier plate 21. The arrangement of the four shock absorber bodies 3 at the four corners of the carrier plate 21 ensures the uniformity of the buffering and shock absorption after the carrier plate 21 is subjected to force. The secondary shock absorbing mechanism 4 is located directly below the tray 24 and is used for the longitudinal secondary shock absorption of the tray 24. The shock absorber body 3 performs the overall preliminary shock absorption on the carrier mechanism 2, while the secondary shock absorbing mechanism 4 realizes the secondary shock absorption of the carrier mechanism 2 by supporting the tray 24.

[0028] The bottoms of the multiple battery cells 5 pass through the corresponding rectangular notches and are located on the tray 24. The multiple battery cells 5 are locked with the carrier 2 by the clamping member 6. After the multiple battery cells 5 are arranged on the carrier 2 in an orderly manner, the battery cells 5 are first connected in series by the aluminum bar, and then the battery body is fixed on the tray 24 by the clamping member 6.

The bottom of the U-shaped buckle plate 61 is fixedly connected to the corresponding slide plate 23 by bolts.

[0030] The bottom ends of the multiple shock absorber bodies 3 are fixedly connected to the bottom inner wall of the box body 111 by screws.

[0031] An extrusion spring on a round rod 42 is sleeved between the two carriers, and a plurality of round rollers 45 for supporting the tray 24 are distributed linearly between the front and rear integration plates 43. After receiving force, the round rollers 45 transmit the force to the support rod 44 through the integration plate 43, and then the support rod 44 drives the carrier to move, thereby stretching the extrusion spring, thereby achieving a buffering and shock absorbing effect.

[0032] The base 41 is provided with a strip guide groove, in which a plurality of sliders are slidably connected, and the tops of the plurality of sliders are respectively fixedly connected to corresponding carriers. The configuration of the strip guide groove and the slider guides the movement of each carrier.

[0033] See also Figure 3 and Figure 8-Figure 11 In the embodiment of the present invention, the blocking mechanism 7 includes a short blocking component 71 and a long blocking component 72 movably connected to the inner wall of the shell 11, and the short blocking component 71 and the long blocking component 72 are connected by a pull rod group 73.

[0034] The inner walls of the box body 111 are provided with receiving grooves for receiving the short blocking components 71 and the long blocking components 72. There are two short blocking components 71, which are respectively located in the receiving grooves on the left and right sides. There are also two long blocking components 72, which are respectively located in the receiving grooves on the front and rear sides.

[0035] The short blocking component 71 and the long blocking component 72 are used to block and adjust the heat dissipation holes opened on the side wall of the box body 111 .

[0036] The short blocking assembly 71 includes a short blocking plate 711 movably connected to the corresponding receiving groove. A plurality of vents corresponding to the corresponding heat dissipation holes are linearly opened on the short blocking plate 711. The vents arranged therein are used as air inlets. Two wing plates 712 are fixedly connected to the side wall of the short blocking plate 711, and a spring telescopic rod 713 is installed on the rear side of the wing plate 712. A support plate is provided at the rear end of the spring telescopic rod 713, and the side wall of the support plate is fixedly connected to the corresponding inner wall of the box body 111. Among them, the two wing plates 712 are symmetrically distributed up and down. The symmetrically arranged spring telescopic rods 713 can ensure the stability of the resetting movement of the short blocking plate 711.

[0037] A fixing arm 714 is also fixedly connected to the side wall of the short blocking plate 711, and a contact plate is fixedly connected to the bottom end of the fixing arm 714. A friction pad is provided at the bottom of the contact plate to increase friction.

[0038] The long blocking assembly 72 includes a long blocking plate 721 movably connected to the corresponding receiving groove. The long blocking plate 721 is also linearly provided with a plurality of vents corresponding to the corresponding heat dissipation holes, and the vents therein are used as air outlets. The long blocking plate 721 is movably connected with a cleaning member 722 for cleaning the vents.

[0039] The cleaning member 722 includes a slide groove group provided on the side wall of the long blocking plate 721, and a horizontal plate slidably connected to the long blocking plate 721 in the slide groove group. A guide rail 7221 is integrally provided on the outer wall of the horizontal plate, and a plurality of sliding sleeves are slidably connected to the guide rail 7221. A plurality of cleaning plates 7222 for cleaning the corresponding vents are linearly distributed on the inner wall of the guide rail 7221. The cleaning plate 7222 is composed of a plate body and a brush, and the plate body is fixedly connected to the horizontal plate, and the brush is close to the vent. After the vent and the corresponding heat dissipation hole overlap, the brush located there will extend into the corresponding heat dissipation hole.

[0040] The pull rod group 73 includes two, which are diagonally distributed. Then the short plugging components 71 at the two sides respectively drive a long plugging component 72 to move. Each pull rod group 73 is composed of two pull rods, wherein both ends of the pull rods are connected with ear plates through movable pins, and the side walls of the ear plates are fixedly connected to the corresponding short plugging plates 711 and the long plugging plates 721, and the two pull rods are symmetrically distributed up and down. The setting of the two pull rods ensures the stability of the traction movement between the short plugging plate 711 and the long plugging plate 721.

[0041] The heat dissipation mechanism 8 is composed of a dual-axis motor 81 and a transmission member. There are two transmission members, which are respectively arranged on both sides of the dual-axis motor 81.

[0042] The double-axis motor 81 is arranged on the bottom inner wall of the box body 111. The transmission member comprises a reciprocating screw 82 mounted on the output end of the double-axis motor 81, and one end of the reciprocating screw 82 away from the double-axis motor 81 is rotatably connected to the corresponding inner wall of the box body 111 through a bearing.

[0043] The top of each reciprocating screw rod 82 is rotatably connected to a rotating shaft located on the corresponding inner wall of the box body 111 through a bearing. A fan blade member 83 is installed at the end of the rotating shaft. The fan blade member 83 will form a blasting effect during the rotation process, thereby performing air cooling on the structure inside the box body 111. The two sides of the fan blade member 83 are arranged to form convection wind during air cooling and heat dissipation, further improving the heat dissipation effect.

[0044] The reciprocating screw 82 and the rotating shaft are linked by a toothed chain 84. The toothed chain 84 is composed of two gears and a chain. The two gears are respectively mounted on the upper and lower corresponding reciprocating screws 82 and the rotating shaft, and the two gears are connected by a chain. Then, when the reciprocating screw 82 moves, the corresponding rotating shaft is synchronously driven to move. The side of the toothed chain 84 is provided with a friction wheel 85 located on the reciprocating screw 82, and the friction wheel 85 is in friction contact with the contact plate.

[0045] Each reciprocating screw rod 82 is threadedly connected with a moving seat, and the moving seat is slidably connected to the bottom inner wall of the box body 111. This ensures that the moving seat can perform linear displacement adjustment when the reciprocating screw rod 82 rotates.

[0046] The front and rear sides of the moving seat are movably connected to the adjusting rod 86 through the mounting pin, and the end of the adjusting rod 86 away from the moving seat is movably connected to the sliding seat through the pin shaft. The sliding seat is slidably connected to the bottom inner wall of the box body 111. When the moving seat moves, the adjusting rod 86 realizes the displacement of each corresponding sliding seat.

[0047] The top pin of the sliding seat is movably connected to a push rod 87, and the top of the push rod 87 is movably connected to a U-shaped seat through a pin, and the side walls of multiple U-shaped seats are respectively fixedly connected to the corresponding sliding sleeves. The displacement of the sliding seat is realized by the push rod 87 to realize the movement of each sliding sleeve, thereby realizing the lifting movement of the cleaning member 722 and achieving its cleaning effect. The sliding setting of the sliding sleeve on the guide rail 7221 ensures that after the displacement adjustment of the long plugging component 72, the push rod 87 can still realize the adjustment of the cleaning member 722.

[0048] The working principle of the present invention is: when the product is in use, the battery management system 9 turns on the dual-axis motor 81 in the heat dissipation mechanism 8, so that the reciprocating screw 82 connected thereto rotates. When the reciprocating screw 82 rotates, it drives the friction wheel 85 arranged thereon to move synchronously, and under the transmission action of the toothed chain member 84, the corresponding rotating shaft rotates synchronously. When the rotating shaft rotates, the fan blade member 83 arranged thereon moves synchronously, thereby achieving a blasting effect.

[0049] Since each friction wheel 85 is in contact with the contact plate of the fixed arm 714 on the short blocking assembly 71 in the blocking mechanism 7, when each reciprocating screw 82 drives the corresponding friction wheel 85 to rotate, the friction wheel 85 drives the contact plate in contact with it to move during the movement, and the corresponding short blocking plate 711 is displaced by the fixed arm 714.

[0050] When the short blocking plate 711 is displaced, it compresses the corresponding spring telescopic rod 713. When the short blocking plate 711 moves to the maximum mileage, the friction wheel 85 is still in friction contact with the corresponding contact plate. However, since the short blocking plate 711 has moved to the maximum mileage, the short blocking plate 711 is in a dynamic stay state at this position, and the corresponding friction wheel 85 is still rotating.

[0051] Since the short blocking plate 711 moves to the maximum distance, the ventilation holes opened thereon respectively overlap with the corresponding heat dissipation holes, thereby acting as an air inlet, so that the outside air enters the interior of the housing 11 under the blowing action of the fan blade 83. In this way, the internal structure of the housing 11 is cooled by wind.

[0052] When each short blocking plate 711 is forced to move, it pulls the corresponding long blocking assembly 72 through the corresponding pull rod group 73 to perform displacement. When the long blocking assembly 72 moves with the movement of the short blocking plate 711, the long blocking plate 721 is simultaneously moved to the maximum mileage when the short blocking plate 711 moves to the maximum mileage. Then, the vents opened on each long blocking plate 721 coincide with the corresponding heat dissipation holes on the housing 11, thereby acting as an air outlet, facilitating the airflow entering the housing 11 to be discharged to the outside of the housing 11.

[0053] The reciprocating screw rod 82 will make the corresponding moving seat threaded thereon perform reciprocating displacement adjustment when rotating. The adjusting rod 86 movably assembled on the moving seat moves during the movement, thereby driving the sliding seat connected thereto to move, and the push rod 87 movably connected thereto is synchronously adjusted during the displacement adjustment process of the sliding seat. When each push rod 87 is adjusted in motion, the front multiple push rods 87 and the rear multiple push rods 87 are consistent in the direction of motion, thereby realizing the lifting and lowering adjustment of the corresponding cleaning member 722 in each long plugging assembly 72. As the cleaning member 722 is lifted and lowered reciprocatingly, the vents and the corresponding heat dissipation holes on the corresponding long plugging plate 721 are brushed and cleaned.

[0054] When the vehicle is bumped, the shock absorber body 3 in the longitudinal buffering component performs longitudinal shock absorption on the supporting mechanism 2 as a whole. After the supporting mechanism 2 is subjected to the initial longitudinal shock absorption, the tray 24 in the supporting mechanism 2 contacts the round roller 45 in the secondary shock absorbing mechanism 4 below it as it continues to move downward. The downward movement of the tray 24 squeezes the round roller 45, and the round roller 45 transmits the force to the integration plate 43. Under the action of the support rod 44, each carrier moves, stretching the squeezing spring, thereby realizing the longitudinal double shock absorption protection of the supporting mechanism 2.

[0055] When the supporting mechanism 2 performs longitudinal shock absorption protection, the pressing member 6 for locking the battery body located on the supporting mechanism 2 contacts the sponge pad 122 located on the shell 11 during the lifting movement of the battery body, thereby further achieving a buffering and shock absorption effect thereon.

[0056] At this time, when the battery body located in the supporting mechanism 2 is performing longitudinal buffering and shock absorption, the battery body is adjusted laterally in the front and rear directions on the carrier plate 21 of the supporting mechanism 2 through the cooperation of the tray 24, the slide plate 23 and the clamping piece 6, and cooperates with the guide rod 22 and the buffer spring group to ensure the lateral buffering and shock absorption of the battery body, thereby realizing multi-directional shock absorption protection for it.

[0057] When the product stops being used, the battery management system 9 turns off the dual-axis motor 81 in the heat dissipation mechanism 8. When the friction wheel 85 stops moving, the corresponding short blocking plates 711 of the blocking mechanism 7 are reset under the reset action of the respective spring telescopic rods 713. At this time, the short blocking components 71 and the long blocking components 72 in the blocking mechanism 7 once again block the corresponding heat dissipation holes opened on the box body 111 in the housing 11.

[0058] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
