Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a multi-hole battery mounting structure. Background Technology

[0002] Multi-hole batteries are rechargeable batteries with multiple independent terminals on the top cover, and multiple terminals leading out from each cell, with each terminal and terminal sealed individually. Relying on multiple terminals to shunt current at multiple points, they have low internal resistance and low heat generation under high current, and are often used in high-power applications such as forklifts and AGVs.

[0003] The multi-hole battery installation cabinet is a steel frame box with layered insulating brackets inside. The battery is placed in a limited position with the terminal posts facing upwards and reserved for wiring space. The cabinet has reserved copper busbar wiring positions and heat dissipation gaps.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] This invention provides, for example Figures 1 to 7 The multi-hole battery mounting structure shown includes a vertical mounting cabinet 1. The vertical mounting cabinet 1 is made of cold-rolled steel, which has high structural strength and is treated with insulating spray coating to meet the dustproof and leakage prevention requirements of multi-hole batteries.

[0023] The front of the vertical mounting cabinet 1 has a through opening for pulling out and placing batteries on the tray 5. Inside the cabinet, multiple parallel trays 5 are slidably assembled in rows. The trays 5 are made of rigid insulating engineering plastic and can directly support and place multi-hole batteries. The trays are positioned by limiting the position of the multi-hole batteries and provide space for wiring and heat dissipation at the top.

[0024] The vertical mounting cabinet 1 has multiple guide rails 6 fixedly installed in pairs on its inner wall. The guide rails 6 are made of silent steel. The pairs of guide rails 6 are matched one-to-one with the layered trays 5. The opening on the front side of the cabinet is located between the two pairs of guide rails 6 in each pair. The sliding limit of a single tray 5 is between the corresponding two guide rails 6. Relying on the guide rails 6 to constrain the tray 5, it can only slide smoothly in the back-and-forth direction, avoiding the problem of tray 5 tilting or jamming under load.

[0025] Each shelf 5 on the side wall of the vertical mounting cabinet 1 is equipped with an independently configured power unit. A small geared motor 4 is used as the drive source, and the motor 4 is bolted to the outer wall of the vertical mounting cabinet 1. A rack 13 is fixed to the bottom surface of the shelf 5 along the sliding direction. A gear 14 is fixedly sleeved on the output shaft of the motor 4. The gear 14 meshes with the rack 13 for transmission. The forward and reverse rotation of the motor 4 drives the rack 13, along with the shelf 5, to automatically pull out or retract along the guide rail 6, realizing the automated extraction, inspection, and storage of multi-hole batteries. Each shelf 5 is equipped with an independent drive structure, allowing for single-layer independent discharge without interfering with batteries in other compartments. It should be noted that each motor 4 is equipped with a brake device.

[0026] Each tray 5 has a pivot shaft horizontally mounted through its front end in the left-right direction, and each pivot shaft is rotatably connected to the tray 5 it is attached to. Each pivot shaft has a hinged door 2 that can be flipped to seal and open. The door 2 is made of flame-retardant insulating material. When the door 2 is flipped above the tray 5, it closes the opening of the vertical mounting cabinet 1. When the door 2 is flipped below the tray 5, it works with the lower tray 5 to provide load-bearing support for the tray 5 it is attached to.

[0027] A torsion spring is fitted on the outer wall of the pivot. The two ends of the torsion spring are respectively limited and fixed between the cabinet door 2 and the support plate 5. Under normal conditions, the spring force drives the cabinet door 2 to keep it closed upward and block the cabinet opening, so as to prevent dust and debris from entering the cabinet and hitting the exposed pole of the multi-hole.

[0028] Each tray 5 and its matching cabinet door 2 are equipped with a linkage component.

[0029] Specifically, the linkage component includes a flexible and wear-resistant tape 12, a fixing block 9 fixed to the side of the support plate 5, the support plate 5 and the fixing block 9 being made of an integral stamped sheet metal part, a support rod fixed to the fixing block 9 along the sliding direction of the support plate 5, the support rod facing rearward and having an axially sliding slider 7 passing through its exterior, and a spring 10 fitted on the outside of the support rod, the two ends of the spring 10 being fixed to the fixing block 9 and the slider 7 respectively.

[0030] A limiting block 11 is fixed on the inner wall of the vertical mounting cabinet 1, and a through hole is provided on the limiting block 11 for the winding belt 12 to slide through. One end of the winding belt 12 is wound and fixed on the pivot where the cabinet door 2 is located, and the other end passes through the through hole of the limiting block 11 and is fixed to the slider 7.

[0031] A clearance groove is provided on the side wall of the guide rail 6 to allow the fixed block 9 to move, and a moving groove 8 is provided on the inner wall of the vertical mounting cabinet 1 to connect with the clearance groove. The moving groove 8 is used to accommodate the slider 7, the fixed block 9, and the support rod to move back and forth synchronously with the tray 5. The limiting block 11 is located in the moving groove 8. When the tray 5 is pulled outward, the limiting block 11 abuts against the slider 7, the spring 10 is stretched, and the winding belt 12 is pulled to pull the rotating shaft to overcome the torsion spring force and drive the cabinet door 2 to flip downward to the bottom surface of the tray 5.

[0032] Two lugs are integrally formed at the end of the cabinet door 2 connecting to the pivot. The two lugs are fixedly connected to the pivot. Two notches are opened at the front end of the tray 5, which correspond one-to-one with the lugs and are adapted to allow the lugs to rotate and avoid each other. The bottom surface of the tray 5 has an inwardly sloping groove 15, which is used to avoid the cabinet door 2 from the lug structure when the cabinet door 2 is flipped down for storage. When the cabinet door 2 is flipped up and fits against the upper edge of the tray 5, it can block the compartment opening. At this time, it is in a limited fit with the top surface of the tray 5. A rubber support block 3 is fixed to the outer surface of each cabinet door 2. When the cabinet door 2 is flipped to the bottom of the tray 5, the support block 3 can abut against the surface of the cabinet door 2 located at the front end of the lower tray 5, forming an auxiliary load-bearing structure with the top support to share the load of the tray 5 after it is fully loaded with multi-hole batteries and improve the overall load-bearing stability.

[0033] Working principle: When the equipment is in standby mode, the tray 5 is completely stored inside the vertical mounting cabinet 1. Under the elastic force of the torsion spring at the pivot, the cabinet door 2 is located above the tray 5 and fits tightly against the upper surface of the tray 5, sealing the front opening of the vertical mounting cabinet 1, isolating dust and moisture, and protecting the exposed terminals of the multi-hole batteries placed inside. Under the pulling force of the spring 10, the winding belt 12 is tightened, the slider 7 and the limit block 11 separate from each other, and the entire linkage assembly is in a tensioned and ready state.

[0034] When it is necessary to install or repair multi-hole batteries, the power unit of the corresponding compartment is activated. The motor 4 drives the gear 14 to rotate. The gear 14 meshes with the rack 13 fixed on the bottom surface of the tray 5, driving the tray 5 to slide forward from the opening of the vertical mounting cabinet 1 along the paired guide rails 6. The fixing block 9 on the side of the tray 5 moves forward synchronously with the tray 5. The fixing block 9, support rod, and slider 7 slide forward along the moving groove 8 on the inner wall of the vertical mounting cabinet 1. The clearance groove opened in the guide rail 6 provides clearance space for the movement of the fixing block 9. As the tray 5 continues to extend outward, the limiting block 11 fixed to the inner wall of the vertical mounting cabinet 1 remains stationary and blocks the slider 7 from moving forward after it contacts the limiting block 11. The tray 5 continues to move forward, causing the spring 10 to be stretched. The slider 7 pulls the winding belt 12, which passes through the hole in the limiting block 11 and pulls the rotating shaft to rotate. The rotating shaft overcomes the preload of the torsion spring and drives the cabinet door 2 to flip downward. The cabinet door 2 uses the notch at the front end of the tray 5 and the inclined groove 15 at the bottom of the tray 5 to complete the rotation and avoidance, and finally flips to the lower side of the tray 5. At the same time, the support block 3 on the outside of the cabinet door 2 on the lower tray 5 corresponds to the position of the cabinet door 2 on the upper tray 5. The upper and lower cabinet doors 2 form an auxiliary support structure with the support block 3 to share the load after the tray 5 is loaded with multi-hole batteries and prevent the tray from deforming under heavy pressure. At this time, the upper tray 5 is completely open, and the operator can freely place multi-hole batteries and connect the terminal copper busbar lines.

[0035] After the battery installation and wiring are completed, the control motor 4 rotates in the reverse direction, driving the tray 5 to retract into the vertical mounting cabinet 1 via gear 14 and rack 13. During this process, spring 10 returns to its original position, the winding tape 12 loosens, and the return force of the torsion spring drives the rotating shaft to rotate in the reverse direction to rewind the tape 12. The cabinet door 2 flips up from below the tray 5 to reset. Then, the tray 5, fixing block 9, support rod, and slider 7 move synchronously. The slider 7 disengages from the limiting block 11, and the tray 5, through the rotating shaft, drives the cabinet door 2 to reseal the front opening of the vertical mounting cabinet 1. After the tray 5 is fully returned to its original position, the entire device returns to its initial closed and protective state.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
