[0004] Although the technical solution in the above patent document realizes the stable loading of the battery in the battery box and its heat dissipation and shock absorption effects, it still has the following defects: during actual use, since the battery realizes stable loading by relying on the expansion of the inner fixing frame in the expansion hole, with the use of the product, the expansion hole and the inner fixing frame are worn, and it is difficult to ensure a perfect fit for the battery, so that the battery will inevitably shake again after being assembled in the battery box, affecting the service life of the battery; the shock absorption effect of the product is single, and it can only realize shock absorption processing in the vertical direction, and it is difficult to ensure the safety of shock absorption and buffering when the product is jolted; in the prior art, the product realizes the heat dissipation effect of the product through the cooperation of a heat dissipation fan and heat dissipation holes, but the open design adopted by the heat dissipation hole structure easily allows external impurities and mosquitoes to enter the inside of the battery box when the product is in a non-use state, thereby damaging its internal structure.

[0029] By arranging a heat dissipation mechanism inside the battery box and cooperating with the heat dissipation holes opened on the battery box, efficient heat dissipation of its interior is achieved. Moreover, a blocking mechanism is configured on the inner wall of the battery box, which combines with the heat dissipation mechanism. Then, when the heat dissipation mechanism operates, the blocking mechanism opens synchronously to ensure the heat dissipation effect of the interior of the battery box. Additionally, a cleaning component is provided on the blocking mechanism, and with the operation of the heat dissipation mechanism, synchronous cleaning of the heat dissipation holes at the air outlet position is achieved, avoiding the problem of blockage of the air outlet caused by the adhesion of impurities. When the heat dissipation mechanism stops operating, the blocking mechanism automatically resets to block the heat dissipation holes opened on the battery box, thereby preventing foreign impurities and mosquitoes from entering the interior of the battery box and damaging its internal structure.

Among them, the battery main body is composed of a plurality of battery cells 5 linearly distributed horizontally. The plurality of battery cells 5 are connected in series through aluminum bars to form an integral whole. The battery box 1 is composed of an outer shell 11 and a top cover 12.

[0043] The outer shell 11 includes a box body 111. Grooves are provided on the outer walls around the box body 111, and a plurality of heat dissipation holes for heat dissipation are equidistantly arranged in the grooves. A rib plate 112 located on the inner wall of the corresponding groove is integrally arranged between two adjacent heat dissipation holes, and the rib plate 112 is used to strengthen the side wall strength of the box body 111. The heat dissipation holes at the left and right sides of the box body 111 serve as air inlets, and filter meshes for filtering air flow are arranged in the heat dissipation holes at this position, while the heat dissipation holes at the front and rear sides serve as air outlets.

[0044] The top cover 12 includes a cover plate 121 located above the outer shell 11. A sponge pad 122 is installed on the inner wall of the top of the cover plate 121, and the cover plate 121 and the box body 111 are fixedly connected by bolts. The connection method between the sponge pad 122 and the cover plate 121 is diverse, and in this embodiment, it is loaded by an adhesive method.

[0045] Inside the housing 11, a bearing mechanism 2 for loading the battery body is provided. Below the bearing mechanism 2, a longitudinal buffer member for buffering and shock absorption and a heat dissipation mechanism 8 for heat dissipation are provided. And a blocking mechanism 7 is movably connected to the inner wall of the housing 11, and a battery management system 9 is provided below the blocking mechanism 7.

An insertion interface is provided on the cover plate 121, and the insertion interface is connected to the battery management system 9 through a wire.

[0046] Please refer to Figures 3 - 7 , in the embodiment of the present invention, the bearing mechanism 2 includes a carrier plate 21, and rectangular through grooves are symmetrically formed on the left and right sides of the carrier plate 21. A plurality of rectangular notches for the cores 5 to pass through are linearly formed horizontally between the two rectangular through grooves. The setting of the rectangular notches facilitates the loading of the cores 5, and has a certain constraining and guiding effect on the loaded cores 5. Inside each rectangular through groove, a guiding rod 22 is provided, and a sliding plate 23 and a buffer spring group are sleeved on the guiding rod 22. A tray 24 for supporting the cores 5 is commonly connected to the bottom outer walls of the two sliding plates 23.

[0047] The sliding plate 23 is slidably connected to the rectangular through groove, and the buffer spring group is composed of two buffer springs, which are respectively located on the front and rear sides of the sliding plate 23. The setting of the buffer spring group enables the tray 24 to perform lateral buffer and shock absorption protection on the battery body loaded thereon, improving the anti-collision effect on the battery body.

[0048] The longitudinal buffer member is composed of a shock absorber main body 3 and a secondary shock absorption mechanism 4. Among them, there are four shock absorber main bodies 3, which are respectively arranged at the four corners of the bottom of the carrier plate 21. The setting of the four shock absorber main bodies 3 at the four corners of the carrier plate 21 ensures the uniformity of buffer and shock absorption when the carrier plate 21 is stressed. The secondary shock absorption mechanism 4 is located directly below the tray 24 and is used for performing longitudinal secondary shock absorption on the tray 24. The shock absorber main body 3 performs overall preliminary shock absorption on the bearing mechanism 2, and the secondary shock absorption mechanism 4 performs secondary shock absorption on the bearing mechanism 2 by supporting the tray 24.

[0049] The bottoms of the plurality of cores 5 respectively pass through the corresponding rectangular notches and are located on the tray 24. The plurality of cores 5 and the bearing mechanism 2 are limited and locked through a pressing member 6. Then, after a plurality of cores 5 are arranged on the bearing mechanism 2 in an orderly manner, the cores 5 are first connected in series through an aluminum row, and then the battery body is limited and fixed on the tray 24 in a manner of pressing and fixing with the pressing member 6.

[0050] The clamping member 6 includes a U-shaped buckle plate 61 pressed onto the battery cell 5. A plurality of partitions 62 are distributed laterally and linearly on the top inner wall of the U-shaped buckle plate 61, and the partitions 62 are used to fill the top gap between two adjacent battery cells 5. The bottom of the U-shaped buckle plate 61 is fixedly connected to the corresponding slide plate 23 by bolts. The setting of each partition 62 is used to further ensure the stability of the assembly of each battery cell 5.

[0051] 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. The secondary shock absorbing mechanism 4 includes a base 41 symmetrically arranged on the bottom inner wall of the box body 111. The base 41 is symmetrically provided with vertical plates, and a round rod 42 is arranged between the two vertical plates. An integration plate 43 is arranged just above the round rod 42, and notches are symmetrically opened on the integration plate 43. Two carriers are sleeved on the round rod 42, and a support rod 44 is movably connected to the carrier through a pin shaft, and the top of the support rod 44 is movably connected to the corresponding notch through a connecting pin.

[0052] 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.

[0053] 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.

[0054] See also Figure 3 and Figures 8 - 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.

[0055] 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.

[0056] 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 .

[0057] The short plugging component 71 includes a short plugging plate 711 movably connected to the corresponding receiving groove. A plurality of ventilation openings corresponding to the respective heat dissipation holes are linearly formed on the short plugging plate 711. The ventilation openings provided at this location are used as air inlets. Two wing plates 712 are fixedly connected to the side wall of the short plugging plate 711, and a spring telescopic rod 713 is installed at 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 reset movement of the short plugging plate 711.

[0058] A fixed arm 714 is also fixedly connected to the side wall of the short plugging plate 711, and a contact plate is fixedly connected to the bottom end of the fixed arm 714. A friction pad is provided at the bottom of the contact plate to increase the friction force.

[0059] The long plugging component 72 includes a long plugging plate 721 movably connected to the corresponding receiving groove. A plurality of ventilation openings corresponding to the respective heat dissipation holes are also linearly formed on the long plugging plate 721, and the ventilation openings at this location are used as air outlets. A cleaning member 722 for cleaning the ventilation openings is movably connected to the long plugging plate 721.

[0060] The cleaning member 722 includes a chute group formed on the side wall of the long plugging plate 721, and a cross plate slidably connected to the long plugging plate 721 in the chute group. A guide rail 7221 is integrally provided on the outer wall of the cross 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 ventilation openings 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. The plate body is fixedly connected to the cross plate, and the brush is close to the ventilation opening. After the ventilation opening coincides with the corresponding heat dissipation hole, the brush located there will extend into the corresponding heat dissipation hole.

[0061] There are two sets of pull rods 73, which are distributed diagonally. Furthermore, the short plugging components 71 at both sides respectively drive a long plugging component 72 to move. Each set of pull rods 73 is composed of two pull rods. Among them, both ends of the pull rod are connected with ear plates through movable pins, and the side walls of the ear plates are fixedly connected to the corresponding short plugging plate 711 and long plugging plate 721. The two pull rods are symmetrically distributed up and down. The arrangement of the two pull rods ensures the stability of the traction movement between the short plugging plate 711 and the long plugging plate 721.

[0062] The heat dissipation mechanism 8 is composed of a double-shaft motor 81 and transmission components. Among them, there are two transmission components, which are respectively arranged on both sides of the double-shaft motor 81.

[0063] The biaxial motor 81 is arranged on the bottom inner wall of the box body 111. The transmission member includes a reciprocating lead screw 82 installed on the output end of the biaxial motor 81, and one end of the reciprocating lead screw 82 far away from the biaxial motor 81 is rotatably connected to the corresponding inner wall of the box body 111 through a bearing.

[0064] Above each reciprocating lead screw 82, there is a rotating shaft rotatably connected to 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 blowing effect during rotation, thereby performing air cooling treatment on the internal structure of the box body 111. Convection air is formed on both sides of the fan blade member 83 during air cooling and heat dissipation, further improving the heat dissipation effect.

[0065] The reciprocating lead screw 82 and the rotating shaft are linked through a toothed chain member 84. The toothed chain member 84 is composed of two gears and a chain. The two gears are respectively mounted on the reciprocating lead screw 82 and the rotating shaft corresponding up and down, and the two gears are connected by a chain. Thus, when the reciprocating lead screw 82 moves, it synchronously drives the corresponding rotating shaft to move. A friction wheel 85 located on the reciprocating lead screw 82 is provided on the side of the toothed chain member 84, and the friction wheel 85 is in frictional contact with the contact plate.

[0066] A moving seat is threadedly connected to each reciprocating lead screw 82, and the moving seat is slidably connected to the bottom inner wall of the box body 111. Thus, it is ensured that the moving seat makes a linear displacement adjustment when the reciprocating lead screw 82 rotates.

[0067] Adjusting rods 86 are movably connected to the front and rear sides of the moving seat through mounting pins. One end of the adjusting rod 86 far away from the moving seat is movably connected to a sliding seat through a pin shaft. The sliding seat is slidably connected to the bottom inner wall of the box body 111. When the moving seat displaces, the corresponding sliding seats perform displacement activities through the adjusting rods 86.

[0068] A push rod 87 is movably connected to the top of the sliding seat through a pin shaft. The top end of the push rod 87 is movably connected to a U-shaped seat through a plug pin. The side walls of multiple U-shaped seats are respectively fixedly connected to the corresponding sliding sleeves. The displacement of the sliding seat realizes the activities of each sliding sleeve through the push rod 87, 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 long plugging component 72 makes a displacement adjustment, the push rod 87 can still adjust the cleaning member 722.

[0069] The working principle of the present invention is as follows: When the product is in use, the battery management system 9 turns on the dual-axis motor 81 in the heat dissipation mechanism 8, causing the reciprocating lead screw 82 connected thereto to perform a rotational motion. When the reciprocating lead screw 82 rotates, the friction wheel 85 provided thereon moves synchronously, and under the driving action of the tooth chain member 84, the corresponding rotating shaft rotates synchronously. When the rotating shaft rotates, the fan blade member 83 provided thereon moves synchronously, thereby achieving a blowing effect.

[0070] Since each friction wheel 85 is in contact with the contact plate of the fixed arm 714 on the short plugging component 71 in the blocking mechanism 7. Thus, when each reciprocating lead screw 82 drives the corresponding friction wheel 85 to rotate, the friction wheel 85 drives the contact plate it contacts to move during the movement. Through the fixed arm 714, the corresponding short plugging plate 711 is displaced.

[0071] When the short plugging plate 711 undergoes a displacement movement, it compresses the corresponding spring telescopic rod 713. When the short plugging plate 711 moves to the maximum mileage, at this time, the friction wheel 85 still makes frictional contact with the corresponding contact plate, but since the short plugging plate 711 has moved to the maximum mileage, the short plugging plate 711 remains in a dynamic stationary state at this position, while the corresponding friction wheel 85 still rotates.

[0072] Since the short plugging plate 711 has moved to the maximum mileage, the ventilation openings formed thereon respectively coincide with the corresponding heat dissipation holes, thereby serving as air inlets, enabling the outside air to enter the interior of the housing 11 under the blowing action of the fan blade member 83. In this way, wind heat dissipation treatment is performed on the internal structure of the housing 11.

[0073] When each short plugging plate 711 is forced to move, it pulls the corresponding long plugging component 72 to perform a displacement movement through the corresponding pull rod group 73. When the long plugging component 72 is displaced following the movement of the short plugging plate 711, the long plugging plate 721 moves to the maximum mileage synchronously when the short plugging plate 711 moves to the maximum mileage. Thus, the ventilation openings formed on each long plugging plate 721 coincide with the corresponding heat dissipation holes on the housing 11, thereby serving as air outlets, facilitating the discharge of the air flowing into the housing 11 to the outside of the housing 11.

[0074] When the reciprocating lead screw 82 rotates, it causes the corresponding moving seats threadedly connected thereto to make reciprocating displacement adjustments. During the movement of the moving seats, the adjusting rods 86 movably assembled thereon move, thereby driving the sliding seats connected thereto to move. During the displacement adjustment of the sliding seats, the push rods 87 movably connected thereto are synchronously adjusted. When the push rods 87 are adjusted in movement, the multiple front push rods 87 and the multiple rear push rods 87 have the same movement direction, thereby realizing the lifting adjustment of the corresponding cleaning members 722 in each long plugging assembly 72. As the cleaning members 722 make reciprocating lifting adjustments, the ventilation openings and the corresponding heat dissipation holes on the corresponding long plugging plates 721 are brushed and cleaned.

[0075] When being jolted, at this time, the shock absorber body 3 in the longitudinal buffer member performs overall longitudinal shock absorption treatment on the bearing mechanism 2. After the bearing mechanism 2 is subjected to the initial longitudinal shock absorption, when it continues to move downward, the tray 24 in the bearing mechanism 2 contacts the round roller 45 in the secondary shock absorption mechanism 4 below it. The downward movement of the tray 24 squeezes the round roller 45, and then the round roller 45 transmits the force into the integration plate 43. Under the action of the support rods 44, each carrier moves, stretching and squeezing the spring, thereby realizing the longitudinal double shock absorption protection of the bearing mechanism 2.

[0076] When the bearing mechanism 2 performs longitudinal shock absorption protection, when the battery body on the bearing mechanism 2 moves up and down, the pressing member 6 for locking the battery body contacts the sponge pad 122 on the outer shell 11, further realizing the shock absorption effect on it.

[0077] At this time, when the battery body in the bearing mechanism 2 performs longitudinal shock absorption, it realizes the lateral adjustment of the battery body in the front-back direction on the carrier plate 21 of the bearing mechanism 2 through the cooperation of the tray 24, the sliding plate 23 and the pressing member 6, and cooperates with the guide rod 22 and the buffer spring group, thereby ensuring the lateral shock absorption of the battery body, and thus realizing the multi-directional shock absorption protection of it.

[0078] 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 wheels 85 of each short plugging assembly 71 in the blocking mechanism 7 stop moving, the corresponding short plugging plates 711 are reset under the reset action of their respective spring telescopic rods 713. At this time, each short plugging assembly 71 and long plugging assembly 72 in the blocking mechanism 7 block the corresponding heat dissipation holes opened on the box body 111 in the outer shell 11 again.

[0079] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
