Description

Technical Field

[0001] This invention belongs to the field of rainproof and heat dissipation technology for battery swapping cabinets for two-wheeled vehicles, and particularly relates to an autonomously adjustable rainproof and heat dissipation system. Background Technology

[0002] Battery swapping cabinets generate heat during operation, especially the power supply used to charge the batteries, which produces a significant amount of heat. Timely heat dissipation is crucial for safe operation. Current battery swapping cabinets primarily use air cooling, specifically ventilation holes on the side walls of the cabinet. However, to accommodate rain protection, these holes are often poorly located and small, resulting in ineffective heat dissipation. While some designs incorporate variable-size ventilation holes, the effective heat dissipation area decreases during rainy weather, significantly impacting the cooling performance and efficiency of air cooling. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an autonomously adjustable rainproof heat dissipation system that can autonomously switch between external circulation heat dissipation mode, internal circulation heat dissipation mode and internal and external dual circulation heat dissipation mode according to sunny and rainy weather, which greatly improves the rainproof heat dissipation performance and efficiency of the battery swapping cabinet.

[0004] Technical solution: To achieve the above objectives, the present invention provides an autonomously adjustable rainproof and heat dissipation system, including a battery swapping cabinet; the battery swapping cabinet has an air intake grille and heat dissipation louvers, and a wind box located inside the cabinet and a rainwater collector located outside the cabinet are arranged at positions corresponding to the heat dissipation louvers; the air outlet of the wind box faces the heat dissipation louvers, and the wind box has an air duct connected to an air valve.

[0005] It includes a first rack and pinion transmission mechanism and a second rack and pinion transmission mechanism; the rainwater collector is oscillating up and down and is installed at the window of the heat dissipation louver. The swing shaft of the rainwater collector is connected to the louver shaft of the heat dissipation louver through the first rack and pinion transmission mechanism, and the swing shaft of the rainwater collector is connected to the valve plug shaft of the air valve through the second rack and pinion transmission mechanism.

[0006] When the rainwater collector swings downwards due to the weight of the collected rainwater overcoming the elastic force, the first rack and pinion drive the louvers of the heat dissipation louvers to gradually fall down and close, and the second rack and pinion drive the valve plug of the air valve to gradually rotate and open; when the rainwater collector swings upwards due to the elastic force overcoming the weight of the rainwater, the first rack and pinion drive the louvers of the heat dissipation louvers to gradually fall up and open, and the second rack and pinion drive the valve plug of the air valve to gradually rotate and close.

[0007] Furthermore, the heat dissipation of this self-regulating rainproof heat dissipation system includes switchable external circulation heat dissipation mode, internal circulation heat dissipation mode, and internal and external dual circulation heat dissipation mode.

[0008] When the louvers are fully open, the air valve is closed, and the air box provides wind driving force so that outside air enters the battery swapping cabinet from the air intake grille and is discharged from the heat dissipation louvers, realizing the air-cooled external circulation heat dissipation mode.

[0009] When the louvers are fully closed, the air valve opens and provides air driving force through the air box, so that outside air enters from the air intake grille and is discharged from the air duct of the air box and circulates in the battery swapping cabinet. The flowing air comes into contact with the louvers that are attached to the rainwater collector and exchanges heat with the rainwater in the rainwater collector to realize the water-cooled internal circulation heat dissipation mode.

[0010] When the louvers are in a semi-open state, between fully open and fully closed, the air valve is partially open. The air box provides air driving force, allowing outside air to enter the battery swapping cabinet from the air intake grille. Part of the air enters and is discharged to the outside through the semi-open louvers, while the other part is discharged through the air duct and circulates inside the battery swapping cabinet, realizing a dual-circulation heat dissipation mode that combines air cooling and water cooling.

[0011] Furthermore, the rainwater collector is connected to the louver mounting bracket of the heat dissipation louver via a swing shaft; the first rack and pinion transmission mechanism includes a first rack, a first guide rod, a first driving gear, and a first driven gear; the first rack is vertically and movably mounted relative to the louver mounting bracket via the first guide rod, the first driving gear is fixedly mounted on the swing shaft of the rainwater collector, the first driven gear is fixedly mounted on the louver shaft of the louver, and the first driving gear and the first driven gear are engaged by the first rack and pinion gear transmission.

[0012] Furthermore, the second rack and pinion transmission mechanism includes a second rack, a second guide rod, a second driving gear, and a second driven gear. The second rack is vertically and movably installed relative to the cabinet of the battery swapping unit via the second guide rod. The second driving gear is coaxially and fixedly installed on the swing shaft of the rainwater collector with the first driving gear. The valve plug of the air valve is installed on the pipe end of the air pipe via the valve plug shaft. The second driven gear is rotatably mounted on the valve plug shaft and fixedly connected to the valve plug. The second rack has a two-tooth segment structure with upper and lower teeth. The upper tooth segment meshes with the second driving gear, and the lower tooth segment meshes with the second driven gear, so that the second driving gear and the second driven gear are engaged by the two-tooth segment structure of the second rack.

[0013] Furthermore, the top of the rainwater collector is densely covered with water inlet holes that connect to its internal water collection chamber. Rainwater enters the water collection chamber of the rainwater collector through the water inlet holes to achieve rainwater collection. The side of the rainwater collector is provided with a drain hole near the bottom, through which the rainwater in the water collection chamber is discharged.

[0014] The water inlet has a greater water inflow rate than the drain outlet has a greater water outflow rate, so that the collected rainwater is temporarily stored in the water collection chamber and the gravity of the rainwater provides the power for the rainwater collector to swing downwards.

[0015] Furthermore, the number and diameter of the water inlet holes are both greater than the number and diameter of the drain holes.

[0016] Furthermore, the top of the rainwater collector is provided with a protrusion at the tail end, forming a baffle perpendicular to the top surface of the rainwater collector.

[0017] Furthermore, a perforated opening is provided between the baffle and the distribution area of ​​the water inlet hole to guide the water collection cavity of the rainwater collector, and the perforated opening extends along the length of the baffle.

[0018] Furthermore, the elastic force on the rainwater collector is provided by the torsion springs of each louver, or by the elastic connection of the elastic element suspended on the battery swapping cabinet; the initial posture of the rainwater collector is a basic horizontal posture that is elastically supported by the torsion springs or elastically pulled by the elastic element.

[0019] Furthermore, it includes a dustproof mesh cover corresponding to the bellows, the dustproof mesh cover being placed over the bellows.

[0020] Beneficial effects: This invention can automatically switch between external circulation heat dissipation mode, internal circulation heat dissipation mode, and internal and external dual circulation heat dissipation mode according to sunny and rainy weather, which greatly improves the rainproof heat dissipation performance and efficiency of the battery swapping cabinet; in rainy weather, the heat dissipation mode can be adjusted according to the amount of rainfall to achieve autonomous selection, which optimizes the rainproof function and enhances the heat dissipation performance, ensuring the operational safety of the battery swapping cabinet.

[0026] The invention will now be further described with reference to the accompanying drawings.

[0027] As attached Figure 1 Appendix Figure 4 and attached Figure 5 As shown, a self-adjusting rainproof and heat dissipation system includes a battery swapping cabinet 1; the battery swapping cabinet 1 has an air intake grille 2 and heat dissipation louvers 3, and a wind box 4 located inside the cabinet and a rainwater collector 5 located outside the cabinet are arranged at positions corresponding to the heat dissipation louvers 3; the air outlet of the wind box 4 faces the heat dissipation louvers 3, and the wind box 4 has an air duct 7 connecting to an air valve 6; it includes a first rack and pinion transmission mechanism 8 and a second rack and pinion transmission mechanism 9; the rainwater collector 5 is oscillating up and down at the window of the heat dissipation louvers 3, and the oscillation shaft 50 of the rainwater collector 5 is connected to the louver shaft 30 of the heat dissipation louvers 3 by the first rack and pinion transmission mechanism 8, and the rainwater... The swing shaft 50 of the collector 5 is driven to the valve plug shaft 60 of the air valve 6 via the second rack and pinion transmission mechanism 9. When the rainwater collector 5 swings downwards due to the weight of the collected rainwater overcoming the elastic force, the louvers 31 of the heat dissipation louvers 3 are driven to gradually fall down and close via the first rack and pinion transmission mechanism 8, and the valve plug 61 of the air valve 6 is driven to gradually rotate and open via the second rack and pinion transmission mechanism 9. When the rainwater collector 5 swings upwards due to the elastic force overcoming the weight of the rainwater, the louvers 31 of the heat dissipation louvers 3 are driven to gradually fall up and open via the first rack and pinion transmission mechanism 8, and the valve plug 61 of the air valve 6 is driven to gradually rotate and close via the second rack and pinion transmission mechanism 9. The heat dissipation of this self-adjusting rainproof heat dissipation system includes switchable external circulation heat dissipation mode, internal circulation heat dissipation mode, and internal and external dual circulation heat dissipation mode. This invention can autonomously switch between external circulation heat dissipation mode, internal circulation heat dissipation mode, and internal and external dual circulation heat dissipation mode according to sunny and rainy weather, greatly improving the rainproof heat dissipation performance and efficiency of the battery swapping cabinet.

[0028] When the louver 31 is fully open, the air valve 6 is closed, and the wind drive force is provided by the air box 4, so that the outside air enters the battery swapping cabinet 1 from the air intake grille 2 and is discharged from the heat dissipation louver 3, realizing the air-cooled external circulation heat dissipation mode. This mode is the heat dissipation mode that is activated in rainless (sunny) weather, and the heat dissipation effect is the best.

[0029] When the louvers 31 are fully closed, the air valve 6 opens, providing air driving force through the air box 4, allowing outside air to enter through the air intake grille 2 and exit through the air duct 7 of the air box 4, circulating within the battery swapping cabinet 1. The flowing air comes into contact with the louvers 31 that are attached to the rainwater collector 5, exchanging heat with the rainwater in the rainwater collector 5 to achieve a water-cooled internal circulation heat dissipation mode. This mode is activated during heavy rain, maximizing rain protection while ensuring heat dissipation, thus guaranteeing the normal operation of the battery swapping cabinet.

[0030] When the louver 31 is in a semi-open state, between fully open and fully closed, the air valve 6 is partially open, and the air box 4 provides air driving force, allowing outside air to enter the battery swapping cabinet 1 from the air intake grille 2. Part of the air entering is discharged to the outside through the semi-open louver 31, while the other part is discharged through the air duct 7 and circulates inside the battery swapping cabinet 1, realizing a dual-circulation heat dissipation mode that combines air cooling and water cooling. This mode is the heat dissipation mode that is activated in light rainy weather, ensuring both heat dissipation and rain protection, and improving the rain protection and safety of the battery swapping cabinet.

[0031] Therefore, this invention can autonomously select the heat dissipation mode according to the amount of rainfall during rainy weather, which optimizes the rainproof function and enhances the heat dissipation performance, thus ensuring the safe operation of the battery swapping cabinet.

[0032] The battery swapping cabinet 1 of the present invention is also equipped with an environmental sensor, including a humidity sensor and a temperature sensor, which are used to monitor the humidity and temperature of the internal environment of the battery swapping cabinet 1 in real time, so that the back-end staff can understand the status of the battery swapping cabinet 1.

[0033] As attached Figure 5 As shown, the rainwater collector 5 is connected to the louver mounting bracket 10 of the heat dissipation louver 3 via a swing shaft 50; the first rack and pinion transmission mechanism 8 includes a first rack 81, a first guide rod 82, a first driving gear 83, and a first driven gear 84; the first rack 81 is vertically and movably installed relative to the louver mounting bracket 10 via the first guide rod 82, the first driving gear 83 is fixedly mounted on the swing shaft 50 of the rainwater collector 5, and the first driven gear 84 is fixedly mounted on the louver shaft 30 of the louver 31, and the first driving gear 83 and the first driven gear 84 are engaged by the first rack 81.

[0034] As attached Figure 4 and attached Figure 5 As shown, the second rack and pinion transmission mechanism 9 includes a second rack 90, a second guide rod 92, a second driving gear 93, and a second driven gear 94. The second rack 90 is vertically and movably installed relative to the cabinet of the battery swapping cabinet 1 via the second guide rod 92. The second driving gear 93 is coaxially and fixedly installed on the swing shaft 50 of the rainwater collector 5 with the first driving gear 83. The valve plug 61 of the air valve 6 is installed on the pipe end of the air pipe 7 via the valve plug shaft 60. The second driven gear 94 is rotatably mounted on the valve plug shaft 60 and is fixedly connected to the valve plug 61. The second rack 90 has a two-tooth segment structure with upper and lower tooth segments. The upper tooth segment 90a meshes with the second driving gear 93, and the lower tooth segment 90b meshes with the second driven gear 94, so that the second driving gear 93 and the second driven gear 94 are engaged by the gear transmission of the second rack 90 with its two-tooth segment structure.

[0035] As attached Figure 2 As shown, the top of the rainwater collector 5 is densely covered with inlet holes 51 that connect to its internal water collection chamber. Rainwater enters the water collection chamber of the rainwater collector 5 through the inlet holes 51, thus collecting rainwater. Drainage holes 52 are provided on the side of the rainwater collector 5 near the bottom, through which rainwater in the water collection chamber is discharged. The water inflow rate of the inlet holes 51 is greater than the water outflow rate of the drain holes 52, allowing the collected rainwater to be temporarily stored in the water collection chamber. The gravity of the rainwater provides the power for the rainwater collector 5 to swing downwards. More specifically, the number and diameter of the inlet holes 51 are greater than the number and diameter of the drain holes 52 to ensure that the inflow rate is greater than the outflow rate, thus achieving the rainproof function.

[0036] To further facilitate the entry of rainwater into the water collection chamber, the top of the rainwater collector 5 is provided with a protrusion at the tail end, forming a baffle 53 perpendicular to the top surface of the rainwater collector 5. A hollow opening 54 is provided between the baffle 53 and the distribution area of ​​the water inlet 51 to guide the water collection chamber of the rainwater collector 5. The hollow opening 54 extends along the length of the baffle 53.

[0037] As attached Figure 1 As shown, the elastic force on the rainwater collector 5 is provided by the torsion springs of each louver 31, or by the elastic connection of the elastic element 20 suspended on the battery swapping cabinet 1; the initial posture of the rainwater collector 5 is a basic horizontal posture that is elastically supported by the torsion springs or elastically pulled by the elastic element 20. The elastic element 20 is preferably a spring or an elastic rope.

[0038] As attached Figure 3 As shown, a dustproof mesh cover 21 corresponding to the air box 4 is included. The dustproof mesh cover 21 covers the air box 4 and serves to prevent dust. The air box 4 consists of a box body and a fan installed at the air inlet of the box body. The air outlet of the box body faces the heat dissipation louvers 3, and the air duct 7 is connected to the box body.

[0039] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
