Description

Technical Field

[0001] The present invention relates to the field of solid-state battery packs, and in particular to a quick-install solid-state battery pack used for gardening equipment. Background Art

[0002] Gardening equipment specifically includes lawn mowers, leaf blowers and hedge shears. Compared with traditional fuel tools, gardening equipment using battery packs has the characteristics of low noise, zero emissions and simple operation. Among them, the solid-state battery pack is a battery assembly structure, in which solid-state batteries are used as battery cells. Unlike traditional liquid batteries, solid-state batteries use solid electrolytes instead of liquid electrolytes. When the existing solid-state battery pack is used on an electric lawn mower, it has the characteristics of small size and easy to carry, so it is widely loved by people.

[0003] The Chinese patent with announcement number CN218648051 U provides a battery pack and a lawn mower. By lowering the height of the battery pack and changing the installation position of the battery pack, the center of gravity of the whole vehicle is greatly lowered, the chassis of the whole vehicle is more stable, and the adaptability to the same space is better. At the same time, the battery pack can be installed under the base, which effectively reduces the size of the chassis, makes the structure more compact, and thus reduces the weight of the whole vehicle.

[0004] To summarize, since the above structure is working outdoors for a long time, in order to make the device suitable for working in rainy weather and to ensure the waterproof function of the battery pack itself, it is usually installed in a sealed manner as a whole. As a result, the heat dissipation effect of the battery module in the battery pack during operation of the device is poor, which affects the overall service life of the battery pack for a long time. At the same time, the lawn mower will shake violently during the mobile work, causing the battery module inside the battery pack to collide with the inner wall of the battery pack, which will cause damage to the battery cells in the battery module. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a quick-install solid-state battery pack for use in gardening equipment to solve the technical problems that the heat dissipation effect of the battery pack is poor during actual use, and the jitter frequency during operation will affect the service life of the battery cells in the battery module.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a quick-install solid-state battery pack for gardening equipment, comprising an outer shell and a cover plate, the outer shell is provided with a heat dissipation frame, and an inner shell is symmetrically provided on both sides of the heat dissipation frame, an elastic airbag is provided at the bottom of the inner shell, and buffer airbags cooperating with the elastic airbags are symmetrically provided on both sides of the inner shell, a bottom plate is slidably provided on the top of the elastic airbag in the inner shell, a limiting plate is symmetrically provided on the top of the bottom plate, and an arc-shaped guide column is elastically provided on one side of the limiting plate, a special-shaped groove cooperating with the arc-shaped guide column is provided in the outer shell at the position of the arc-shaped guide column, a first through hole and a second through hole are respectively provided on the cover plate and the heat dissipation frame, and one end of the second through hole passes through the bottom of the inner shell and is connected to a heat dissipation fin tube.

[0007] By adopting the above technical scheme, the positioning of the battery module is completed with the cooperation of the arc guide column and the special-shaped groove, and the elastic airbag is deformed and discharged into the buffer airbags on both sides during the sliding of the bottom plate, so that the buffer airbag wraps the battery module. When working in rainy weather, rainwater will be discharged into the heat dissipation fin tube at the bottom along the first through hole and the second through hole, effectively preventing the erosion of the battery module by rainwater, and taking away the heat generated by the battery module during operation through the action of the heat dissipation fin tube.

[0008] The present invention is further configured such that a slide groove is provided on the bottom plate at the arc-shaped guide column, and a sliding block cooperating with the limit plate is slidably provided in the slide groove.

[0009] By adopting the above technical solution, the arc guide column and the special-shaped groove cooperate with each other, so that the arc guide column drives the slider to slide to one side, and the slider drives the limit plate to slide to one side under the action of the slide groove, ensuring sliding in the horizontal direction and preventing the limit plate from tilting.

[0010] The present invention is further configured such that a driving block is slidably arranged in a slide groove on the bottom plate, a support rod is hinged on the top of the driving block, and a top plate is hinged on the other end of the support rod.

[0011] By adopting the above technical solution, when the battery module is placed on the top of the base plate, the buffer airbag will wrap the battery module. In order to ensure the overall heat dissipation of the battery module, the support will lift up the top plate as a whole, so that the battery module is suspended on the base plate. Since the bottom area of ​​the top plate is smaller than the bottom area of ​​the battery module, the heat dissipation of the battery module itself will not be affected when the buffer airbag wraps the battery module.

[0012] The present invention is further configured such that a groove is provided on the bottom plate for the top plate to be inserted into.

[0013] By adopting the above technical solution, under normal conditions, the top plate is flush with the floor, which makes it easy for workers to position the battery module through the top plate, further improving the overall practicality of the device.

[0014] The present invention is further configured such that one end of the heat dissipating fin tube passes through the shell and is connected to a drain pipe, and a wedge-shaped block is arranged inside the heat dissipating fin tube and is inclined in the opposite direction to the water flow direction.

[0015] By adopting the above technical solution, rainwater flowing through the heat dissipating fin tubes will be discharged to the outer shell through the drain pipe. In this process, the fluidity of rainwater in the heat dissipating fin tubes is guaranteed, so that the heat generated by the battery module can be cooled. In addition, the wedge-shaped blocks in the heat dissipating fin tubes are convenient for blocking part of the water flow, ensuring that the water source is retained in the heat dissipating fin tubes for a long time, and further improving the overall heat dissipation effect of the device in cooperation with air cooling in the subsequent process.

[0016] The present invention is further configured such that the second through hole is located in the heat dissipation frame and is inclined.

[0017] By adopting the above technical solution, it is convenient for outside air to flow into the heat dissipation fin tube through the second through hole when the lawn mower moves, thereby extending the service life of the entire device.

[0018] The present invention is further configured such that a heat insulating sheet is provided on the inner side of the buffer airbag.

[0019] By adopting the above technical solution, the thermal insulation sheet effectively prevents direct contact between the buffer airbag and the battery module, and further protects the buffer airbag itself to prevent damage to the buffer airbag itself due to long-term contact.

[0020] The present invention is further configured such that the cover plate is concavely configured, and the first through hole is located at the concave portion of the cover plate.

[0021] By adopting the above technical solution, the concave setting makes it easier for rainwater to flow to the concave part of the cover in rainy weather, effectively preventing rainwater from accumulating on the top of the cover, and further reducing the erosion of rainwater on the internal battery module.

[0022] The present invention is further configured such that the contact surface between the special-shaped groove and the arc-shaped guide pillar is configured to be smooth.

[0023] By adopting the above technical solution, the sliding friction between the special-shaped groove and the arc-shaped guide column is reduced during the sliding of the arc-shaped guide column, ensuring that the arc-shaped guide column can slide stably through the special-shaped groove, thereby improving the overall stability of the device.

[0024] The present invention is further configured such that a rough surface is provided on the top of the bottom plate.

[0025] By adopting the above technical solution, the rough surface increases the sliding friction between the bottom plate and the bottom of the battery module, preventing slight vibrations during operation, which may cause the battery module to shift in position, and further improves the limiting effect on the battery module.

[0026] In summary, the present invention mainly has the following beneficial effects: 1. The present invention drives the bottom plate to slide downward under the action of the battery module's own gravity. During this process, the arc-shaped guide column will slide downward with the bottom plate, thereby driving the limit plate to move to one side of the battery module in cooperation with the special-shaped groove, thereby completing the limit work of the battery module and realizing the rapid assembly of the battery module. In addition, during the sliding process of the bottom plate, the elastic airbag at the bottom will deform, and the excess gas inside will be discharged into the buffer airbags on both sides, so that the buffer airbag wraps the battery module. During the working process, the buffer airbag greatly reduces the vibration impact force on the battery module, thereby completing the effective protection of the battery core; 2. The present invention provides a first through hole and a second through hole on the cover plate and the heat dissipation frame respectively. After assembly, the first through hole matches the second through hole. When working in rainy weather, rainwater will be discharged into the heat dissipation fin tube at the bottom along the first through hole and the second through hole, thereby preventing rainwater from accumulating on the top of the shell, effectively preventing rainwater from corroding the battery module, and taking away the heat generated by the battery module during the working process through the heat dissipation fin tube, thereby improving the overall heat dissipation effect of the device. At the same time, the second through hole itself is inclined, which is convenient for outside air to be poured into the second through hole during the movement of the lawn mower, thereby extending the overall service life of the device; 3. The present invention provides a top plate slidingly on the bottom plate. When the battery module is placed on the top of the bottom plate, the buffer airbag will wrap the battery module. At this time, the support will lift up the top plate as a whole, so that the battery module is suspended on the bottom plate. Since the bottom area of ​​the top plate is smaller than the bottom area of ​​the battery module, the heat dissipation of the battery module itself will not be affected when the buffer airbag wraps the battery module.

DETAILED DESCRIPTION

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] Embodiment 1 A quick-install solid-state battery pack for gardening equipment, such as Figure 1-Figure 7 As shown, it includes an outer shell 1, a cover plate 2, a battery module, a heat dissipation mechanism, a sealing mechanism and a limiting mechanism. A heat dissipation frame 4 is provided on the outer shell 1, and an inner shell 5 is symmetrically provided on both sides of the heat dissipation frame 4, wherein an elastic air bag 11 is provided at the bottom of the inner shell 5, and a bottom plate 10 is slidably provided on the top of the elastic air bag 11 in the inner shell 5. When assembling, the staff places the battery module to be installed on the top of the bottom plate 10, and the bottom plate 10 slides downward under the action of the gravity of the battery module itself. Since a limiting plate 8 is symmetrically provided on the top of the bottom plate 10, and an arc-shaped guide column 19 is elastically provided on one side of the limiting plate 8, and a special-shaped groove 13 matched with the arc-shaped guide column 19 is provided in the outer shell 1, during the process of the bottom plate 10 sliding down, the arc-shaped guide column 19 will follow the bottom plate 10 to move in the special-shaped groove 13, thereby driving the limiting plate 8 to move to one side of the battery module, thereby completing the limiting work of the battery module, and realizing the rapid assembly of the battery module; In addition, buffer airbags 9 cooperating with the elastic airbags 11 are symmetrically arranged on both sides of the inner shell 5, wherein the buffer airbags 9 and the elastic airbags 11 are connected through a valve. When the bottom plate 10 is driven downward by the action of the battery module, the elastic airbag 11 at the bottom will be squeezed, so that the elastic airbag 11 is deformed, and the excess gas inside is discharged into the buffer airbag 9 through the valve. At this time, the air intake of the buffer airbag 9 is expanded, and the battery module is wrapped as a whole. During the working process, the buffer airbag 9 greatly reduces the vibration impact force on the battery module, thereby completing the effective protection of the battery cell, and the inner side of the buffer airbag 9 is provided with a heat insulation sheet, which effectively prevents the direct contact between the buffer airbag 9 and the battery module, and further protects the buffer airbag 9 itself, and prevents the buffer airbag 9 itself from being damaged due to long-term contact; After the battery module is quickly installed, the cover plate 2 is limited to the top of the shell 1 by the action of the bolt assembly. Since the cover plate 2 and the heat dissipation frame 4 are respectively provided with a first through hole 3 and a second through hole 6, and the first through hole 3 and the second through hole 6 after assembly are matched, when working in rainy weather, since the cover plate 2 is concavely set, and the first through hole 3 is located at the concave part of the cover plate 2, the concave setting is convenient for rainwater to flow to the concave part of the cover plate 2 in rainy weather, effectively preventing rainwater from accumulating on the top of the cover plate, further reducing the erosion of the internal battery module by rainwater, and then the rainwater flows through the first through hole 3 to the second through hole 6 on the heat dissipation frame 4, wherein one end of the second through hole 6 penetrates to the bottom of the inner shell 5 and is connected to a heat dissipation fin tube 12, and the heat generated by the battery module during operation is taken away by the action of the heat dissipation fin tube 12, thereby improving the overall heat dissipation effect of the device and extending the overall service life of the device.

[0032] See also Figure 5 A slide groove 14 is provided on the bottom plate 10 at the arc guide column 19, and a slider cooperating with the limit plate 8 is slidably arranged in the slide groove 14. Under the cooperation of the arc guide column 19 and the special-shaped groove 13, the arc guide column 19 will drive the slider to slide to one side, so that the slider will drive the limit plate 8 to slide to one side under the action of the slide groove, ensuring sliding in the horizontal direction to prevent the limit plate 8 from tilting.

[0033] See also Figure 3One end of the heat dissipating fin tube 12 passes through the shell 1 and is connected to a drain pipe 7, and a wedge-shaped block is arranged in the heat dissipating fin tube 12 in an opposite direction to the water flow direction. Rainwater flowing through the heat dissipating fin tube 12 will be discharged to the shell 1 through the drain pipe 7. In this process, the fluidity of rainwater in the heat dissipating fin tube 12 is guaranteed, so that the heat generated by the battery module can be cooled, and the wedge-shaped block in the heat dissipating fin tube 12 is convenient for blocking part of the water flow, so as to ensure that the water source is retained in the heat dissipating fin tube 12 for a long time, and further improve the overall heat dissipation effect of the device in cooperation with air cooling in the subsequent process.

[0034] See also Figure 1 The second through hole 6 is located in the heat dissipation frame 4 and is tilted in the direction of movement of the lawn mower. In rainy weather, rainwater will flow into the heat dissipation fin tube 12 along the first through hole 3 and the second through hole 6. In normal weather, when the lawn mower is working, part of the outside air will flow into the heat dissipation fin tube 12 through the second through hole 6 during its own movement. In this process, the outside air will cooperate with the residual water source in the heat dissipation fin tube 12 to further improve the heat dissipation of the battery module, thereby extending the overall service life of the device.

[0035] Embodiment 2 like Figure 8 and Fig. 9 The quick-install solid-state battery pack shown is used for garden equipment. Its overall structure is similar to that of Example 1, wherein a driving block 18 is slidably arranged in the slide groove 14 on the bottom plate 10. When the battery module is placed on the top of the bottom plate 10, the buffer airbag 9 will wrap the battery module. At this time, the arc guide column 19 will drive the limit plate 8 to slide to one side under the action of the special-shaped groove 13. In this process, in order to ensure the overall heat dissipation of the battery module, the limit plate 8 will push the bottom driving block 18 to move to one side. Since a support rod 17 is hinged at the top of the driving block 18, and a top plate 15 is hinged at the other end of the support rod 17, the support rod 17 will lift the top plate 15 as a whole, thereby making the battery module located on the bottom plate 10 in a suspended setting. Since the bottom area of ​​the top plate 15 is smaller than the bottom area of ​​the battery module, the heat dissipation of the battery module itself will not be affected when the buffer airbag 9 wraps the battery module.

[0036] See also Fig. 9A groove 16 for the top plate to be inserted into is provided on the bottom plate 10. Under normal conditions, the top plate 15 is located flush with the bottom plate 10. When the staff places the battery module on the bottom plate 10, it is ensured that the battery module itself will not tilt, which is convenient for the staff to position the battery module through the top plate 15 and ensure that the top plate 15 is in the middle of the battery module. In the subsequent process of lifting the top plate 15, the battery module is prevented from tilting, thereby further improving the overall practicality of the device.

[0037] The working principle of the present invention is as follows: when in use, the battery module to be installed is placed on the top of the bottom plate 10, and then the bottom plate 10 slides downward under the action of the gravity of the battery module itself. During this process, the arc guide column 19 on one side of the bottom plate 10 will follow and move downward. Since one end of the arc guide column 19 is in the special-shaped groove 13 in the outer shell 1, the limit plate 8 will be pushed to slide to one side during the downward movement of the arc guide column 19, thereby achieving the limiting work of the battery module on the bottom plate 10, thereby accelerating the overall installation efficiency, and the bottom plate 10 will also squeeze the elastic airbag 11 at the bottom, so that the elastic airbag 11 itself is deformed, and the gas is discharged into the buffer airbags 9 on both sides of the inner shell 5. At this time, the buffer airbags 9 complete the wrapping work of the battery module; Subsequently, the staff installs the cover plate 2 on the top of the outer shell 1 through the action of the bolt assembly. Since the first through hole 3 and the second through hole 6 are respectively provided on the cover plate 2 and the heat dissipation frame 4, when the lawn mower is working in rainy weather, rainwater will flow along the first through hole 3 and the second through hole 6 to the heat dissipation fin tube 12 at the bottom of the inner shell 5, and the flowing rainwater will take away the heat generated by the battery module during operation, thereby improving the overall heat dissipation effect of the device.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the present invention.
