Description

Technical Field

[0001] This utility model belongs to the field of battery charging and discharging detection technology, specifically relating to battery charging and discharging devices. Background Technology

[0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable, achieving recharging through a reversible chemical reaction. It typically refers to lead-acid batteries, a type of secondary battery. Its working principle is as follows: during charging, external electrical energy is used to regenerate the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output, such as in commonly used mobile phone batteries.

[0003] During battery maintenance, charge and discharge tests are required. The common method is to connect the two electrodes of the battery with wires for charging. However, when testing multiple batteries, workers need to move and arrange them neatly on the ground or test platform. Most test platforms on the market are fixed structures, and the size and spacing of their placement slots or support frames are not adjustable. Fixed test platforms lack sufficient flexibility when dealing with batteries of different specifications. When the platform area is large, it is necessary to move the batteries back and forth for placement and stacking, which is cumbersome. Summary of the Invention

[0004] The purpose of this invention is to provide a battery charging and discharging device to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A battery charging and discharging device includes two support blocks, with a plurality of rollers rotatably connected between the two support blocks for placing the battery, and a first support leg and a second support leg respectively connected below the two support blocks. An adjustment component is slidably connected to the first support leg and the second support leg, and the adjustment component is used to move and adjust the placement space of the roller; A clamping assembly is disposed on one side of the adjusting assembly, and the adjusting assembly is used to mutually restrict the second support leg.

[0006] Preferably, the system also includes a reinforcing column, through which the two support blocks are respectively welded to the inner sides of the first support leg and the second support leg. The reinforcing column is used to raise the welding height of the support blocks.

[0007] Preferably, the adjustable distance assembly includes a first mounting post, a second mounting post, and a crossbeam. The first mounting post and the second mounting post are welded together via the crossbeam. The bottom opposite surfaces of the first mounting post and the second mounting post are connected to sliders, which are slidably connected to the first support leg and the second support leg.

[0008] Preferably, both ends of the first support leg and the second support leg are connected to mounting blocks, and a sliding rod is connected between the two mounting blocks, with the slider and the sliding rod being slidably assembled.

[0009] Preferably, both the first mounting post and the second mounting post are equipped with height-adjustable side wing components, which are used to close the two sides of the roller to prevent the battery from falling off the roller.

[0010] Preferably, the side wing component includes an L-plate and a positioning groove. The positioning groove is vertically arranged from above the first mounting post and the second mounting post. One end of the L-plate is provided with a U-shaped groove that matches the shape of the first mounting post and the second mounting post. A threaded sleeve that fits the shape of the positioning groove is detachably connected in the U-shaped groove. An adjusting screw is rotatably connected in the positioning groove, and the threaded sleeve is threaded onto the adjusting screw.

[0011] Preferably, the clamping assembly includes a clamping block, a U-shaped handle, and an extension rod. The bottom end of the U-shaped handle is connected to the clamping block, and the extension rod is disposed near the top end of the U-shaped handle. Both the U-shaped handle and the extension rod are slidably inserted into the second mounting post for connection.

[0012] Preferably, the first limiting block and the second limiting block are made of magnetic material.

[0013] Preferably, the side of the second support leg is provided with external teeth, and the side of the locking block facing the second support leg is provided with a tooth-like structure that meshes with the external teeth.

[0014] Preferably, the support block is welded backward at an angle via a reinforcing column.

[0015] The technical solution of this utility model has the following beneficial effects: 2. When the battery is placed on the roller surface, the longitudinal area of ​​the battery placement can be adjusted by moving the pitch adjustment component; then, combined with the clamping component, the position of the pitch adjustment component is restricted. That is, when the pitch adjustment component slides to any position, the clamping component can lock the current position of the pitch adjustment component to prevent the pitch adjustment component from sliding; an adjustable range test platform can be provided for battery charging and discharging testing.

[0016] 3. Pushing the battery causes the roller to rotate, which greatly improves the ease of operation. When repeatedly placing multiple sets of batteries, pushing the first battery can easily adjust the position of the batteries behind it, eliminating the need for staff to walk back and forth to move the batteries and stack them in designated locations.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. Example 1:

[0028] refer to Figure 1 A battery charging and discharging device includes two support blocks 103, and a plurality of rollers 104 are rotatably connected between the two support blocks 103. The rollers 104 are used for placing the battery 40. A first support leg 10 and a second support leg 101 are respectively connected below the two support blocks 103. In the above scheme, when the battery 40 is being charged and discharged, the battery 40 can be neatly placed on the surface of the roller 104, and the roller 104 can be rotated by pushing the battery 40, which greatly improves the convenience of operation. When multiple sets of batteries 40 are repeatedly placed, the position of the rear batteries 40 can be easily adjusted by pushing the front battery 40. The front ends of the first support leg 10 and the second support leg 101 are longer than the support block 103, while the rear ends are flush. The first support leg 10 and the second support leg 101 are used to support the ground and perform the load-bearing function.

[0029] Note: For ease of drafting, the lengths of rollers 104 and support blocks 103 are not limited. The specific lengths of rollers 104 and support blocks 103 are determined based on actual usage and the testing scale of the batteries 40. The longer the roller 104, the more batteries 40 can be accommodated laterally; the longer the support block 103, the more batteries 40 can be placed in the longitudinal X direction. Furthermore, a longer roller 104 means a larger distance between the two support blocks 103 and a greater number of rollers 104. In actual production, the load-bearing deformation of rollers 104 needs to be considered to avoid deformation and bending of rollers 104 due to an excessive number of batteries 40 placed on them.

[0030] refer to Figures 1-6 The adjusting component 20 is slidably connected to the first support leg 10 and the second support leg 101. The adjusting component 20 is used to move and adjust the placement space of the roller 104. The clamping component 30 is disposed on one side of the adjusting component 20, and the adjusting component 20 is used to mutually restrict the second support leg 101.

[0031] In the above scheme, when the battery 40 is placed on the roller 104, the longitudinal placement area of ​​the battery 40 can be adjusted by moving the pitch adjustment component 20. (Refer to...) Figure 1 In detail, when the pitch adjustment component 20 moves in the X direction, the distance that could originally accommodate two or more batteries 40 can be reduced to the distance that accommodates one battery 40. Similarly, when it moves in the opposite X direction, it can accommodate x groups of batteries 40 (x represents the number) in the same longitudinal direction. The stacking of x groups of batteries 40, combined with the rollers 104, allows for rapid arrangement and placement without the need for staff to walk back and forth to move the batteries 40 to the designated location. In this arrangement, the last battery 40 in the same column of the stacked batteries 40 rests against the pitch adjustment component 20 to stabilize the position of the battery 40.

[0032] Then, the holding component 30 restricts the position of the adjusting component 20. That is, when the adjusting component 20 slides to any position, the holding component 30 can hold the adjusting component 20 in its current position to prevent the adjusting component 20 from sliding. Based on the above solutions, an adjustable-range test platform can be provided for the charge and discharge testing of batteries.

[0033] It should be noted that this product is suitable for testing rectangular batteries 40.

[0034] refer to Figure 5 It also includes a reinforcing column 102. Two support blocks 103 are welded to the inner sides of the first support leg 10 and the second support leg 101 respectively through the reinforcing column 102. The reinforcing column 102 is used to raise the welding height of the support block 103.

[0035] In the above scheme, the height of the reinforcing column 102 determines the welding height of the support block 103. Since the first support leg 10 and the second support leg 101 are supported on the ground, the installation height of the support block 103 is extended by the reinforcing column 102, which makes it easier for workers to place the battery 40 on the surface of the roller 104 without having to bend over to move the battery 40. At the same time, there is a gap between the battery 40 and the ground, so the heat dissipation effect at the bottom can be improved during the charging and discharging test of the battery 40, avoiding the safety problem caused by the accumulation of heat at the bottom of the battery 40.

[0036] refer to Figure 1 , Figure 3 and Figure 7 The adjustable distance assembly 20 includes a first mounting post 201, a second mounting post 202, and a crossbeam 203. The first mounting post 201 and the second mounting post 202 are welded together through the crossbeam 203. The bottom opposite surfaces of the first mounting post 201 and the second mounting post 202 are connected to a slider 209, which is slidably connected to the first support leg 10 and the second support leg 101.

[0037] In the above scheme, the crossbeam 203 is used to support the battery 40, that is, the last battery 40 in the same longitudinal column is supported on the crossbeam 203; the height of the first mounting post 201 and the second mounting post 202 are not limited by length, and need to be adjusted according to the height of the battery 40 being tested. It should be noted that during the drafting process, Figure 7 The crossbeam 203 in the middle is more than Figure 1 and Figure 3 The number of crossbeams 203 is large because when the height of the first mounting post 201 and the second mounting post 202 is relatively high, additional crossbeams 203 are required so that the crossbeams 203 can block the battery 40; and the height of the first mounting post 201 and the second mounting post 202 is as follows. Figure 1 In this state, the crossbeam 203 is welded to the top of the first mounting post 201 and the second mounting post 202, and can be used to block the battery 40, so there is no need to add an additional crossbeam 203.

[0038] refer to Figure 3 The first support leg 10 and the second support leg 101 are both connected to mounting blocks 106, and a slide rod 107 is connected between the two mounting blocks 106. The slider 209 is slidably assembled with the slide rod 107.

[0039] In the above scheme, by means of the cooperation between the slide bar 107 and the slider 209, the crossbeam 203 can be pulled to freely slide and adjust the position of the first mounting post 201 and the second mounting post 202 at the same time. The sliding range of the first mounting post 201 and the second mounting post 202 is limited by the length of the slide bar 107.

[0040] refer to Figure 1 , Figure 4 and Figure 6 Both the first mounting post 201 and the second mounting post 202 are equipped with height-adjustable side wing components. The side wing components are used to close the two sides of the roller 104 to prevent the battery 40 from falling off the roller 104.

[0041] In the above scheme, the side wing components are positioned to block in the lateral direction, thereby... Figure 1 In this configuration, the battery 40 can be placed close to the side wing components, which block the left and right directions, while the crossbeam 203 blocks the rear of the battery 40, further preventing the battery 40 from slipping off the roller 104.

[0042] Preferred Solution Reference Figure 4The side wing component includes an L-plate 205 and a positioning groove 204. The positioning grooves 204 are vertically arranged from above the first mounting post 201 and the second mounting post 202. One end of the L-plate 205 is provided with a U-shaped groove 206 that matches the shape of the first mounting post 201 and the second mounting post 202. A threaded sleeve 207 that matches the shape of the positioning groove 204 is detachably connected in the U-shaped groove 206. An adjusting screw 208 is rotatably connected in the positioning groove 204. The threaded sleeve 207 is threadedly engaged with the adjusting screw 208.

[0043] In the above scheme, the short side of the L-plate 205 has a U-shaped groove 206, which can fit well with the first mounting post 201 and the second mounting post 202, facilitating installation. With the use of the adjusting screw 208, rotating the adjusting screw 208 can raise or lower the threaded sleeve 207, that is, adjust the height position of the L-plate 205. The purpose of adjusting the height of the L-plate 205 is to ensure that the L-plate 205 can contact the side of the battery 40, and adjust the appropriate height according to the usage needs. There are three posts evenly spaced at the top of the adjusting screw 208, which can be used as handles to facilitate the operator to rotate the adjusting screw 208. It should be noted that the adjusting screws 208 on the first mounting post 201 and the second mounting post 202 are independently set. There are several usage scenarios. First, when the battery 40 does not cover the entire lateral direction of the rollers 104, meaning that the battery 40 is only in contact with one of the L-plates 205, it is not necessary to adjust the other adjusting screw 208. Second, when the battery 40 covers the entire lateral direction of the rollers 104, meaning that the battery 40 is in contact with both L-plates 205, it is necessary to rotate and adjust both adjusting screws 208 simultaneously. Adjusting both adjusting screws 208 does not mean that the L-plates 205 on both sides are parallel. A roughly appropriate height is sufficient. It does not need to be so precise. It is only necessary to ensure that the L-plates 205 can contact the side of the battery 40. It should also be noted that, as mentioned above, when the height of the first mounting column 201 and the second mounting column 202 is relatively long, two crossbeams 203 will be set, one near the top and one near the bottom. Therefore, the L-plate 205 needs to be set between the two crossbeams 203 to ensure sufficient travel for height adjustment.

[0044] refer to Figures 1-3 The holding assembly 30 includes a locking block 301, a U-shaped handle 302, and an extension rod 303. The bottom end of the U-shaped handle 302 is connected to the locking block 301, and the extension rod 303 is positioned near the top end of the U-shaped handle 302. Both the U-shaped handle 302 and the extension rod 303 are slidably inserted into the second mounting post 202 for connection. Both the U-shaped handle 302 and the extension rod 303 are provided with a first limiting block 304 and a second limiting block 305.

[0045] In the above scheme, both the U-shaped handle 302 and the extension rod 303 are slidably inserted into the second mounting post 202 for connection, thereby positioning the U-shaped handle 302 on the second mounting post 202. The first limiting block 304 and the second limiting block 305 limit the maximum distance of the U-shaped handle 302 to slide in the left and right directions. When the U-shaped handle 302 is pulled outward, the second limiting block 305 will contact the surface of the second mounting post 202, which is the maximum displacement distance of the U-shaped handle 302, and the locking block 301 will move away from the surface of the second support leg 101. When the U-shaped handle 302 is pushed inward, the first limiting block 304 will also contact the surface of the second mounting post 202, which is the maximum displacement distance of the U-shaped handle 302, and the locking block 301 will contact the surface of the second support leg 101.

[0046] Preferred Solution Reference Figure 3 The first limiting block 304 and the second limiting block 305 are made of magnetic material.

[0047] In a preferred embodiment, the first mounting post 201 and the second mounting post 202 are made of metal that can be magnetically attracted. The magnetic material can be attracted to the surface of the second mounting post 202, thus fixing the position of the U-shaped handle 302. It should be noted that the positions of the first limiting block 304 and the second limiting block 305 are a certain distance apart, so there will be no problem that when one limiting block is attracted, the other limiting block will be attracted by the magnetic force. Moreover, the opposite surfaces of the first limiting block 304 and the second limiting block 305 are installed in the direction of the like poles repulsion principle, that is, the south poles correspond to each other or the north poles correspond to each other.

[0048] refer to Figure 3 The side of the locking block 301 facing the second support leg 101 has a gap that engages with the second support leg 101. The side of the second support leg 101 is provided with external teeth 105, and the gap on the locking block 301 is set as a tooth shape that engages with the external teeth 105.

[0049] The toothed structure interlocks with each other, which can limit the displacement of the adjusting component 20, that is, the sliding of the first mounting post 201 and the second mounting post 202. When it is necessary to move the adjusting component 20, the U-shaped handle 302 needs to be pulled to disengage the outer teeth 105 from the locking block 301. Example 2:

[0050] refer to Figure 8 In the middle, the support block 103 is welded backward at an angle through the reinforcing column 102. The inclined support block 103 allows the battery 40 placed on the roller 104 to automatically slide towards the crossbeam 203, improving the ease of operation; the tilt angle should not be too large to avoid the battery 40 sliding with excessive inertia and causing a collision. Figure 8 The dashed line in the middle represents a horizontal line.

[0051] It should be noted that because the batteries 40 are tilted backward, the stacking of multiple batteries 40 will generate pressure on the crossbeam 203. The material quality of the crossbeam 203 needs to be able to withstand the weight of the batteries 40. It needs to be a material with both hardness and rigidity, specifically steel or other metal alloys.

[0052] The specific implementation process of this embodiment is as follows: The batteries 40 are neatly arranged on the surface of the rollers 104 for charge and discharge testing; Pulling the crossbeam 203 allows the first mounting post 201 and the second mounting post 202 to slide and adjust their positions simultaneously. Rotating the adjusting screw 208 allows the threaded sleeve 207 to rise or fall, thus adjusting the height of the L-plate 205 so that it can contact the side of the battery 40.

[0053] Pulling the U-shaped handle 302 outward will cause the second limiting block 305 to contact the surface of the second mounting post 202, which is the maximum displacement distance of the U-shaped handle 302. The locking block 301 will move away from the surface of the second support leg 101, thereby allowing the first mounting post 201 and the second mounting post 202 to move. Pushing the U-shaped handle 302 inward will cause the first limiting block 304 to contact the surface of the second mounting post 202, which is the maximum displacement distance of the U-shaped handle 302. The locking block 301 will contact the surface of the second support leg 101, at which point the first mounting post 201 and the second mounting post 202 cannot be moved.
