Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery charging, and in particular relates to a charging device for a lead-acid battery in an adaptive current charging mode. Background Art

[0002] To ensure the service life and usage time of lead-acid batteries, lead-acid batteries have strict requirements on the size of their charging current and the level of their voltage. Different charging states are required under different battery voltages or capacities, or large current constant current charging is required, or constant voltage trickle charging is required, etc. Too high or too low voltage, current or wrong charging method can easily cause the lead-acid battery to be damaged or not fully charged, seriously affecting its actual use.

[0003] Chinese invention CN117498501A discloses an adaptive charging protection system for lead-acid batteries. The constant current charger adjusts the constant current according to the corresponding charging voltage and enters the first charging stage. The constant voltage charger adjusts the corresponding constant voltage according to the second terminal voltage and enters the second charging stage. The charging feedback device is used to detect whether the lead-acid battery body generates gassing. If gassing occurs, the lead-acid battery body is switched from the first charging stage to the second charging stage, so that the lead-acid battery reaches the optimal charging state and prolongs the service life of the lead-acid battery.

[0004] However, the charging connector in the prior art is clamped on the positive charging interface or the negative charging interface through the connecting buckle, which makes it very inconvenient for the connecting buckle to clamp the battery pole, resulting in poor overall convenience of use. Summary of the invention

[0005] The purpose of the present invention is to provide a charging device with an adaptive current charging method for lead-acid batteries. By pressing a pressing column and using a driving block to drive a clamping block to move toward a side away from a wiring block, it is convenient to insert a battery pole between the clamping block and the wiring block, thereby solving the problem of inconvenient clamping of the existing pole and poor overall convenience of use.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] As a preferred technical solution of the present invention, an arc-shaped notch adapted to the battery pole is opened on the side of the wiring block.

[0009] As a preferred technical solution of the present invention, an arc-shaped clamping opening corresponding to the position of the arc-shaped notch is opened on the side of the clamping block.

[0010] As a preferred technical solution of the present invention, the driving block has a driving surface inclined relative to the length direction of the pressing column, and the follower structure has an inclined surface matching the driving surface, which is used to achieve synchronous movement of the clamping block when the driving block moves through the cooperation between the driving surface and the inclined surface.

[0011] As a preferred technical solution of the present invention, there are two driving surfaces, which are arranged in a V-shaped surface structure. The follower structure has two inclined surfaces, which respectively cooperate with the two driving surfaces. Pressing columns are connected on both sides of the driving block, so that pressing any pressing column can drive the clamping block to move.

[0012] As a preferred technical solution of the present invention, the driving block has a driving surface that is inclined relative to the length direction of the pressing column, and the follower structure is a follower that matches the driving surface.

[0013] As a preferred technical solution of the present invention, both of the pressing columns are sleeved with a compression spring, and one end of the compression spring is against the inner wall of the shell, so that when the pressing column is pressed, the compression spring sleeved on the other pressing column is compressed.

[0014] As a preferred technical solution of the present invention, a push switch is provided on the top wall of the installation cavity, so that when the push switch is triggered by the compression of the battery pole, the charging device energizes the wiring block.

[0015] As a preferred technical solution of the present invention, the clamping block is made of insulating material.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0033] Embodiment 1

[0034] See also Figures 1 to 4 As shown, the present invention is a charging device for a lead-acid battery with an adaptive current charging method. The charging device is configured in the prior art and includes two charging connectors 1. The charging connector 1 includes a shell 101. The lower end of the shell 101 has an installation cavity 102, and the interior has a closed electrical installation cavity. The installation cavity 102 is connected to a clamping assembly 2, and is slidably connected to a driving block 3.

[0035] like Figures 5 to 7 As shown, the clamping assembly 2 includes a wiring block 201 fixedly connected to the housing 101, and the upper end of the wiring block 201 is inserted into the electrical installation cavity. Two flat-head guide pillars 202 are fixedly connected to one side of the wiring block 201, and a clamping block 203 is movably inserted through the two flat-head guide pillars 202. The material of the clamping block 203 is an insulating material, such as a ceramic material or a rubber material.

[0036] The flat-head guide column 202 is sleeved with a spring 204, one end of the spring 204 abuts against the clamping block 203, and the other end abuts against the head of the end of the flat-head guide column 202, thereby pushing the clamping block 203 toward the wiring block 201, and using the clamping block 203 and the wiring block 201 to clamp the battery pole 401.

[0037] The side of the junction block 201 is provided with an arc-shaped notch 205 adapted to the battery pole 401. The side of the clamping block 203 is provided with an arc-shaped clamping opening 206 corresponding to the position of the arc-shaped notch 205, so that the arc-shaped notch 205 and the arc-shaped clamping opening 206 are adapted to the circumferential surface of the battery pole 401 to improve the clamping stability.

[0038] like Figure 8 As shown, the driving block 3 is provided with a straight slot, and a screw passes through the straight slot and is connected to the bottom wall of the installation cavity 102, so that the driving block 3 can slide along the length direction of the straight slot, and the driving block 3 is also made of insulating material. The driving block 3 is connected to a pressing column 301 that passes through the side wall of the housing 101, and the pressing column 301 extends to the outside of the housing 101, so that pressing the pressing column 301 can cause the driving block 3 inside the housing 101 to move.

[0039] The clamping block 203 is provided with a follower structure, which cooperates with the driving block 3 and is used to drive the clamping block 203 to move toward the side away from the wiring block 201 by pressing the pressing column 301. When charging is required, the pressing column 301 is pressed to increase the distance between the clamping block 203 and the wiring block 201, so that the battery pole 401 is inserted between the clamping block 203 and the wiring block 201. The pressing column 301 is released, and the clamping block 203 and the wiring block 201 clamp the battery pole 401 under the action of the spring 204, thereby greatly improving the overall convenience of use.

[0040] Among them, Figures 6 to 8 As shown, the driving block 3 has a driving surface 302 which is inclined relative to the length direction of the pressing column 301, and the follower structure has an inclined surface 303 which cooperates with the driving surface 302, forming a wedge block structure, which is used to cooperate with the inclined surface 303 through the driving surface 302 to achieve synchronous movement of the clamping block 203 when the driving block 3 moves.

[0041] At the same time, there are two driving surfaces 302, which are arranged in a V-shaped surface structure, and the follower structure has two symmetrically arranged inclined surfaces 303, which respectively cooperate with the two driving surfaces 302. Both sides of the driving block 3 are connected with pressing columns 301, so that pressing any pressing column 301 can drive the clamping block 203 to move, so that the charging connector 1 is more flexible and convenient when connected to the battery pole 401, further improving the convenience of use.

[0042] Embodiment 2

[0043] like Fig. 9As shown, the driving block 3 has a driving surface 302 which is inclined relative to the length direction of the pressing column 301, and the follower structure is a follower 304 which cooperates with the driving surface 302. Compared with the first embodiment, the follower 304 cooperates with the driving block 3, and the sliding cooperation is changed to rolling cooperation, thereby improving the convenience of moving the driving block 3 by pressing the pressing column 301. In this embodiment, there are also two driving surfaces 302 of the driving block 3, so that pressing any one of the pressing columns 301 can drive the clamping block 203 to move.

[0044] At the same time, both pressing columns 301 are sleeved with compression springs 305, and one end of the compression spring 305 is against the inner wall of the shell 101, and the other end is against the inner wall of the shell 101. When the pressing column 301 is pressed, the compression spring 305 sleeved on the other pressing column 301 is squeezed by the driving block 3 and compressed. When the pressing column 301 is released, the driving block 3 can be quickly reset under the action of the compression spring 305, thereby ensuring the reliability of use.

[0045] Embodiment 3

[0046] like Figure 2 As shown, based on Example 1 or Example 2, a push switch 103 is provided on the top wall of the installation cavity 102, and the push switch 103 is connected to the control circuit in the charging head 1. During charging, when the clamping block 203 and the terminal block 201 clamp the battery pole 401, the upper end of the battery pole 401 pushes the push switch 103, so that when the push switch 103 is squeezed and triggered by the battery pole 401, the charging device energizes the terminal block 201. After the charging head 1 is unplugged, the terminal block 201 is powered off, thereby avoiding leakage and effectively improving the overall safety of use.
