Description

Technical Field

[0001] This invention relates to the field of new energy vehicle battery manufacturing, and more specifically to a new energy vehicle battery. Background Technology

[0002] With the continuous development of society and economy, and the constant progress and innovation of science and technology, new energy vehicles have emerged. These vehicles can operate solely on electricity without the need for petroleum resources, offering advantages such as environmental protection and energy conservation. However, relying on batteries inevitably leads to the problem of generating a large amount of heat during battery discharge. Although current new energy vehicles have cooling devices, most are simply structures of heat sinks and fans with limited cooling effectiveness and relatively wasteful of energy. Furthermore, dust easily accumulates on the batteries. Additionally, the significant vibrations generated when driving on uneven roads can easily damage the batteries and reduce their lifespan. Therefore, it is necessary to design a new energy vehicle battery to solve these problems. Summary of the Invention

[0003] This invention provides a new energy vehicle battery, the purpose of which is to provide heat dissipation during the operation of the new energy vehicle battery and to quickly retract in an emergency to protect the battery.

[0004] The above objectives are achieved through the following technical solutions:

[0005] A new energy vehicle battery includes a housing and two cover plates. Two rotating shafts I and two rotating shafts II are fixedly connected to the front side of the housing. A connecting rod I is rotatably connected to each of the two rotating shafts I, and a connecting rod II is rotatably connected to each of the two rotating shafts II. Rotating shafts III and IV are fixedly connected to each of the two cover plates. The other end of the connecting rod I is rotatably connected to the corresponding rotating shaft III, and the other end of the connecting rod II is rotatably connected to the corresponding rotating shaft IV.

[0006] The front side of the housing is rotatably connected to two gears, which mesh with each other; each of the two rotating shafts I is rotatably connected to a half gear, which meshes with the corresponding gear; and each of the two half gears is fixedly connected to the corresponding connecting rod I.

[0007] Two rotating shafts VI are fixed to the front side of the movable frame, and a connecting rod III is rotatably connected between the corresponding rotating shaft III and rotating shaft VI.

[0008] The cover plate has an opening on its inner side, and multiple heat sinks are rotatably connected to the opening. Each heat sink is fixed to the cover plate with a torsion spring, which causes the heat sink to rotate to an angle perpendicular to the cover plate.

[0009] The inner side of the movable frame is fixedly connected to guardrail I; baffles II are fixedly connected to the front and rear sides of the movable frame, and guardrails II are fixedly connected to baffles II; guardrails III are fixedly connected to the left and right sides of the movable frame.

[0010] Handles are fixed to the left and right sides of the movable frame, respectively.

[0011] The front and rear sides of the box are respectively fixed with baffle I; the bottom of the box is fixed with a bottom plate.

[0012] The box has a vertically penetrating cavity, and a battery rack and a push plate are slidably connected inside the cavity; batteries are fixedly connected to the battery rack.

[0013] Two scissor linkage mechanisms are installed between the base plate and the push plate; the fixed ends of two telescopic rods are fixedly connected to the base plate, and the movable ends of the telescopic rods are fixedly connected to the corresponding scissor linkage mechanisms. The telescopic rods can drive the scissor linkage mechanisms to extend upward or retract downward.

[0014] The front and rear sides of the box are respectively fixed with baffles I, and the four corners of the bottom plate are respectively fixed with sliding grooves. Each of the four sliding grooves is slidably connected with a sliding rod, and the four sliding rods are fixed below the baffles II.

[0015] The beneficial effects of the new energy vehicle battery of the present invention are as follows:

[0016] Compared to existing new energy vehicle batteries, this invention, through a linkage and gear structure, enables the opening and closing of two covers and the raising and lowering of the internal battery, thereby achieving the functions of heat dissipation and protection for the battery: when the two covers are open, the internal battery rises, and the heat sink opens, accelerating the cooling of the internal components of the invention and the battery itself; when the two covers are closed, the battery descends back into the housing, thus protecting the battery.

Detailed Implementation

[0031] refer to Figure 1-6 The diagram shows an embodiment of the structural installation of connecting rod I 103 and connecting rod II 105 in this invention.

[0032] Two rotating shafts I102 and two rotating shafts II104 are fixedly connected to the front side of the housing 101. A connecting rod I103 is rotatably connected to each of the two rotating shafts I102, and a connecting rod II105 is rotatably connected to each of the two rotating shafts II104. Two rotating shafts III202 and IV203 are fixedly connected to each of the two cover plates 201. The other end of the connecting rod I103 is rotatably connected to the corresponding rotating shaft III202, and the other end of the connecting rod II105 is rotatably connected to the corresponding rotating shaft IV203.

[0033] The rotating shafts I102 and II104 on the front side of the housing 101, and the rotating shafts III202 and IV203 on the cover plate 201, provide mounting positions for connecting rods I103 and II105, respectively. The rotation of a set of connecting rods I103 and II105 allows the cover plate 201 to rotate from above the housing 101 to the side of the housing 101. Compared to a single connecting rod driving the cover plate 201, a set of connecting rods I103 and II105 can stabilize the rotation trajectory of the cover plate 201. Simultaneously, two sets of connecting rods I103 and II105 are also installed on the rear side of the housing 101 to further prevent the cover plate 201 from shifting during rotation. The connecting rods I103 and II105 are staggered in the front-rear direction, ensuring that they do not interfere with each other during rotation.

[0034] refer to Figure 1-6 The diagram shows an embodiment of the structural installation of connecting rod I 103 and connecting rod II 105 in this invention.

[0035] Two gears 107 are rotatably connected to the front side of the housing 101, and the two gears 107 are meshed together; half gears 106 are rotatably connected to the two rotating shafts I 102, and the two half gears 106 are meshed with the corresponding gears 107 respectively; the two half gears 106 are fixedly connected to the corresponding connecting rods I 103 respectively.

[0036] By connecting the two half-gears 106 to the two gears 107 respectively, and by connecting the two gears 107 to each other, the two half-gears 106 can rotate synchronously and symmetrically. At the same time, the two half-gears 106 are fixedly connected to the corresponding connecting rods I 103 respectively, thereby enabling the connecting rods I 103 on both sides to rotate synchronously and symmetrically, thus enhancing the stability and synchronicity of the connecting rods I 103 driving the cover plates 201 on both sides to rotate.

[0037] refer to Figure 1-6 The diagram shows an embodiment of the structural installation of the movable frame 301 and the connecting rod Ⅲ303 in this invention.

[0038] Two rotating shafts VI 302 are fixedly connected to the front side of the movable frame 301, and a connecting rod Ⅲ 303 is rotatably connected between the corresponding rotating shaft Ⅲ 202 and rotating shaft VI 302.

[0039] The movable frame 301 is linked with the cover plates 201 on both sides by the connecting rod Ⅲ303: when the movable frame 301 moves upward, it can pull the connecting rod Ⅲ303 and thus pull the cover plates 201 on both sides to rotate outward and close to the left and right sides of the box body 101; when the movable frame 301 moves downward, it can push the connecting rod Ⅲ303 and thus push the cover plates 201 on both sides to rotate inward and close to the top of the box body 101.

[0040] refer to Figure 1-8 The diagram shows an embodiment of the outward-expanding structure of the heat sink 204 in this invention.

[0041] The cover plate 201 has an opening on its inner side, and a plurality of heat sinks 204 are rotatably connected in the opening. Each heat sink 204 is fixed to the cover plate 201 with a torsion spring, which causes the heat sink 204 to have a tendency to rotate to an angle perpendicular to the cover plate 201.

[0042] Multiple heat sinks 204 are installed on the inner side of each cover plate 201. By installing torsion springs, each heat sink 204 can be positioned perpendicular to the cover plate 201 when not restricted by external force. When the movable frame 301 moves upward and the two cover plates 201 are respectively pressed against the left and right sides of the box 101, the heat sinks 204 can rotate and unfold to increase the heat dissipation area and assist in heat dissipation inside the box 101. When the movable frame 301 moves downward and the two cover plates 201 rotate inward, the angle between the cover plate 201 and the movable frame 301 decreases, thereby pressing the heat sinks 204 to rotate back to the inner side of the cover plate 201, thus protecting the battery 402 that is stored inside the box 101.

[0043] refer to Figure 1-7 The diagram shows an embodiment of the structural installation of guardrail I 304, guardrail II 306 and guardrail III 307 in this invention.

[0044] The inner side of the movable frame 301 is fixedly connected to a guardrail I 304; the front and rear sides of the movable frame 301 are respectively fixedly connected to a baffle II 305, and a guardrail II 306 is fixedly connected to the baffle II 305; the left and right sides of the movable frame 301 are respectively fixedly connected to a guardrail III 307; at the same time, the left and right sides of the movable frame 301 are respectively fixedly connected to a handle 308.

[0045] Guardrails I 304, II 306, and III 307 are each equipped with multiple protective bars. When the movable frame 301 moves upward, causing the internal battery 402 to move upward, guardrails I 304, II 306, and III 307 have a large gap, which enhances ventilation and improves heat dissipation. When the movable frame 301 moves downward, causing the battery 402 to retract into the housing 101, guardrails I 304, II 306, and III 307 move to the outside of the housing 101, protecting the housing 101 and the internal battery 402. The handles 308 on both sides provide a handhold, and by simultaneously pushing and pulling the handles 308 on both sides, the movable frame 301 can be driven to move upward or downward.

[0046] refer to Figure 1-11 The diagram shows an embodiment of the structural installation of the battery holder 401 and the battery 402 in this invention.

[0047] Baffles I108 are fixedly connected to the front and rear sides of the housing 101 respectively; a bottom plate 501 is fixedly connected to the bottom of the housing 101; at the same time, a cavity that runs vertically through the housing 101 is provided inside the housing 101, and a battery rack 401 and a push plate 502 are slidably connected inside the cavity; a battery 402 is fixedly connected to the battery rack 401.

[0048] The baffles I 108 on the front and rear sides of the housing 101 can protect the connecting rods I 103, II 105, half gear 106, and III 303 on the inner side. The back of the baffle I 108 is provided with a groove that does not affect the rotation of the connecting rod I 103. The battery rack 401 is located outside the battery 402 and can fix and protect the battery 402 at the same time. The push plate 502 can push the battery rack 401 and the battery 402 upward, so that when the battery 402 is needed, it can be pushed out of the cavity inside the housing 101. At the same time, it pushes the movable frame 301 upward, so that a good environment for heat dissipation of the battery 402 is formed above the housing 101.

[0049] refer to Figure 1-13 The diagram shows an embodiment of the structural installation of the telescopic rod 504 driving the scissor linkage mechanism 503 to extend and retract in this invention.

[0050] Two scissor linkage mechanisms 503 are installed between the base plate 501 and the push plate 502; the fixed ends of two telescopic rods 504 are fixedly connected to the base plate 501, and the movable ends of the telescopic rods 504 are fixedly connected to the corresponding scissor linkage mechanism 503. The telescopic rods 504 can drive the scissor linkage mechanism 503 to extend upward or retract downward.

[0051] When the telescopic rod 504 retracts, it drives the scissor linkage mechanism 503 to extend upward, thereby driving the push plate 502 to move upward and pushing the battery 402 upward, thus achieving better heat dissipation. When the telescopic rod 504 extends, it drives the scissor linkage mechanism 503 to retract downward, thereby driving the push plate 502 to move downward, allowing the battery 402 to move downward and return to the inside of the housing 101, thus achieving a protection function.

[0052] refer to Figure 1-13 The diagram shows an embodiment of the structural installation of the slide groove 505 and slide rod 506 in this invention.

[0053] Slide grooves 505 are fixedly connected to the four corners of the base plate 501, and slide rods 506 are slidably connected in each of the four slide grooves 505. The four slide rods 506 are fixedly connected to the bottom of the baffle plate II 305.

[0054] The slide groove 505 can limit the movement trajectory of the slide bar 506, so that the slide bar 506 will not deviate during the up and down movement; at the same time, the four slide grooves 505 correspond to the four slide bars 506 respectively, which can stabilize the up and down movement of the movable frame 301.
