Description

Technical Field

[0001] This utility model belongs to the field of battery testing technology, specifically relating to a pressure-fitting adapter module and a battery charging and discharging testing device. Background Technology

[0002] Battery charge / discharge testing equipment uses probes to press against the battery to monitor the electrical activity during the charging and discharging process. Specifically, during testing, it is necessary to ensure that the positive and negative probes are stably connected to the positive and negative terminals of the battery, respectively, and that a certain distance is maintained between the positive and negative probes to avoid short circuits.

[0003] When conducting charge / discharge testing on small batteries such as wearable batteries, the small battery size results in a small contact area between the battery and the probes, leading to a small distance between the positive and negative probes. This poses a risk of short circuits between the positive and negative electrodes and requires high positioning accuracy from the probes. Furthermore, to accommodate the small contact area, the positive and negative probes must be mounted on the same probe module, making it impossible to construct separate positive or negative probe modules. This results in poor compatibility, meaning the system is only compatible with batteries of a specific size. Utility Model Content

[0004] The purpose of this invention is to provide a pressing adapter module and a battery charging and discharging testing device to solve the problems in the existing battery charging and discharging testing devices when testing small batteries, such as the small distance between the positive and negative probes, the risk of short circuit, the high requirements for probe positioning accuracy, and the poor compatibility of the positive and negative probes sharing the same probe module.

[0005] To achieve the above objectives, the first aspect of this utility model provides a pressing adapter module, including a plurality of adapter units corresponding one-to-one with a battery. Each adapter unit includes two conductive adapters spaced apart. The conductive adapters include a first contact end for contacting the battery and a second contact end for contacting a probe. The distance between a pair of first contact ends is less than the distance between a pair of second contact ends.

[0006] In one or more embodiments, the conductive adapter includes a first extension and a second extension, an angle being formed between the first extension and the second extension, a first contact end being disposed at the end of the first extension, and a second contact end being disposed on the surface of the second extension.

[0011] In one or more embodiments, the second extension is fitted to the adapter plate.

[0012] In one or more embodiments, the first extension section extends along the thickness direction of the adapter plate, and the second extension section extends along the length direction of the adapter plate.

[0013] In one or more embodiments, the end face of the first contact end is provided with a plurality of grooves and / or protrusions.

[0014] In one or more embodiments, the end face of the first contact end is a sawtooth surface with equal tooth pitch.

[0016] To achieve the above objectives, a second aspect of this utility model provides a battery charge / discharge testing device, comprising:

[0022] In one or more embodiments, the pressing adapter module further includes an adapter plate embedded in the upper recess of the tray.

[0023] The advantages of this application, which differ from existing technologies, are:

[0024] The pressing adapter module of this application provides a larger contact area for the probes by setting a conductive adapter, which can significantly improve the probe spacing, avoid the problem of probe short circuit, and at the same time help improve the connection stability between the probe and the battery, reduce the requirements for probe positioning accuracy, and allow a pair of probes to be set on different probe modules, making it easy to adjust the spacing to adapt to different batteries and improve compatibility.

[0038] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0039] Please see Figure 1 , Figure 1 This is a schematic diagram showing the connection between the probe and the battery in existing battery charging and discharging equipment. For example... Figure 1 As shown, during battery charge / discharge testing, the probes 401 for the positive and negative terminals must be pressed into contact with the terminals 200 and the casing 201 of the battery 20, respectively, and a certain distance must be maintained between the probes 401 for the positive and negative terminals to avoid short circuits. However, when testing small batteries such as wearable batteries, the small diameter of the battery 20 results in a small contact area between the battery 20 and the probes 401. Achieving contact between the probes 401 for the positive and negative terminals and the battery 20 within this small area will inevitably reduce the spacing between the probes 401, posing a risk of short circuit between the positive and negative terminals, and also requiring high positioning accuracy for the probes 401.

[0040] In particular, because the spacing between the positive and negative probes 401 is small, the positive and negative probes 401 need to share the same probe module 410, which makes the spacing between them non-adjustable and leads to poor compatibility.

[0041] To address the aforementioned issues, the applicant has developed a pressing adapter module that effectively increases the spacing between the positive and negative electrode probes, avoids the risk of short circuits, ensures a stable connection between the probes and the battery, and enhances the compatibility of testing equipment.

[0042] Specifically, please refer to Figure 2 , Figure 2 This is a schematic diagram of one embodiment of the pressing adapter module of this application.

[0043] like Figure 2As shown, the pressing adapter module 30 includes multiple adapter units 300. Each adapter unit 300 corresponds to a battery and a pair of probes. Each adapter unit 300 includes two conductive adapters 301 spaced apart. The conductive adapters 301 include a first contact end 3011 for contacting the battery and a second contact end 3012 for contacting the probes. The distance d1 between the pair of first contact ends 3011 is smaller than the distance d2 between the pair of second contact ends 3012.

[0044] Understandably, since the spacing between a pair of second contact ends 3012 is greater than the spacing between a pair of first contact ends 3011, the spacing between a pair of probes can be effectively increased by setting the conductive adapter 301, thereby avoiding the risk of short circuit.

[0045] In order to install the conductive adapter 301, the pressing adapter module 30 in this embodiment also includes an adapter plate 302, and multiple adapter units 300 can be arranged sequentially and at intervals on the adapter plate 302.

[0046] The structure and working principle of the conductive adapter 301 are described in detail below, taking into account the structure of the battery charging and discharging equipment. Please refer to [link / reference needed]. Figures 3 to 5 , Figure 3 This is a cross-sectional structural schematic diagram of one embodiment of the battery charging and discharging device of this application. Figure 4 yes Figure 3 A magnified view of part A in the diagram. Figure 5 This is a schematic diagram of one embodiment of the conductive adapter of this application.

[0047] like Figure 3 As shown, the battery charging and discharging device includes a tray 10, and the tray 10 has an internal accommodating space 100 for accommodating a plurality of batteries 20 arranged in sequence.

[0048] The pressing adapter module 30 can be arranged above the tray 10. In particular, the adapter plate 302 can be positioned in the recessed area on the upper part of the tray 10 to limit the position of the adapter plate 302, improve the positional accuracy and stability of the adapter plate 302, and use the tray 10 to achieve precise positioning of the pressing adapter module 30 and the battery 20, reducing the multi-level positioning tolerances existing in traditional testing.

[0049] A probe module 40 is arranged above the pressing adapter module 30. The probe module 40 includes probe units 400 that correspond one-to-one with the adapter unit 300. Each probe unit 400 includes two probes 401 that correspond one-to-one with the conductive adapter 301. The probes 401 are used to connect with the corresponding conductive adapter 301.

[0050] Understandably, through the switching action of the two conductive adapters 301, the two probes 401 can be connected to the same battery 20 to achieve charge and discharge detection.

[0051] The structure of the conductive adapter 301 is described in detail below, such as Figure 4 and Figure 5 As shown, the conductive adapter 301 includes a first extension 3013 and a second extension 3014 connected in sequence, wherein a first contact end 3011 is disposed at the end of the first extension 3013 and a second contact end 3012 is disposed on the surface of the second extension 3014.

[0052] Specifically, the first extension segment 3013 extends along the thickness direction y of the adapter plate 302, and the second extension segment 3014 extends along the length direction x of the adapter plate 302.

[0053] The probe 401 has a probe end 4011 at its end for contacting the corresponding second contact surface 30121.

[0054] Understandably, the first extension segment 3013 extends along the x-direction and is arranged to contact the battery 20, while the second extension segment 3014 extends along the y-direction. The probe 401 contacts the second contact end 3012 on the surface of the second extension segment 3014 to achieve conductivity with the battery 20. The pair of probes 401 can be electrically connected to the terminal post 200 and the housing 201 of the battery 20 respectively through two conductive adapters 301. Therefore, the spacing between the pair of probes 401 can be effectively increased, effectively avoiding the problem of short circuit of the probes 401.

[0055] Specifically, in this embodiment, the conductive adapter 301 is disposed through the adapter plate 302, the first contact end 3011 is arranged below the adapter plate 302 and contacts the battery 20, and the second extension 3014 is located above the adapter plate 302 so that it can contact the probe 401.

[0056] In this embodiment, the second extension segment 3014 extends along the length direction x of the adapter plate 302, which can maximize the spacing between the probes 401 in a limited space; at the same time, in order to improve the stability when the conductive adapter 301 contacts the probes 401, the second extension segment 3014 is fitted to the adapter plate 302.

[0057] Understandably, during testing, probe 401 can press the second extension 3014 against the surface of adapter plate 302 to ensure connection stability. In other embodiments, the second extension 3014 may not extend horizontally; for example, it may extend in a direction inclined relative to the horizontal, which can also achieve the purpose of increasing the spacing between probes 401.

[0058] Furthermore, in this embodiment, the second extension segment 3014 is fixedly disposed with the adapter plate 302. The second extension segment 3014 has an opening, and is fixed to the adapter plate 302 as a whole by bolts passing through the opening, thereby further improving the fixing stability of the conductive adapter 301. In other embodiments, the second extension segment 3014 can also be fixed to the adapter plate 302 as a whole by a fixing method, such as adhesive bonding, or the second extension segment 3014 may not be fixed to the adapter plate 302, all of which can effectively achieve the purpose of increasing the spacing of the probes 401.

[0059] In this embodiment, the first extension segment 3013 extends along the thickness direction y of the adapter plate 302. In other embodiments, the first extension segment 3013 may not extend vertically. For example, it may extend in a direction that is inclined relative to the vertical in a direction away from the other conductive adapter plate 302, which can also achieve the effect of this embodiment.

[0060] In addition, in this embodiment, the first extension segment 3013 and the second extension segment 3014 are directly connected as one unit to form an L-shaped conductive adapter 301; in other embodiments, the first extension segment 3013 may not be directly connected to the second extension segment 3014. For example, other extension segments may be provided between the first extension segment 3013 and the second extension segment 3014, such as chamfered connection segments, rounded corner connection segments, etc., all of which can achieve the effect of this embodiment.

[0061] To optimize the layout of probe 401 and improve detection accuracy, in this embodiment, the two conductive adapters 301 of the same adapter unit 300 are symmetrically arranged with respect to the center line of battery 20. In other embodiments, the two conductive adapters 301 can also be arranged asymmetrically. For example, the length of the second extension 3014 of one conductive adapter 301 can be greater than that of the other conductive adapter 301, etc., as long as stable contact between the conductive adapter 301 and battery 20 and probe 401 can be achieved.

[0062] In this embodiment, there is sufficient spacing between the two probes 401 of the same probe unit 400. Therefore, each probe unit 400 includes two independent probe modules 410. The two probes 401 can be disposed on the two probe modules 410 respectively, so as to control the spacing of the probes 401 by adjusting the spacing of the probe modules 410, so as to adapt to the detection of different models of batteries 20 and improve compatibility.

[0063] Of course, in other embodiments, the two probes 401 can also be arranged on the same probe module 410, which can also improve the effect of avoiding short circuits of probes 401.

[0064] The conductive adapter 301 in this application can be customized based on the battery type 20, making it easy to replace and helping to improve the compatibility of the testing equipment.

[0065] In this embodiment, the conductive adapter 301 can be a one-piece molded copper strip. In other embodiments, the conductive adapter 301 can also be made of any other conductive material, all of which can achieve the effect of this embodiment. Preferably, the conductive adapter 301 can be made of an elastic material to increase the pressing force between the conductive adapter 301 and the battery 20 and improve contact stability.

[0066] To facilitate testing operations, the battery charge / discharge testing device in this embodiment further includes a pressing drive module (not shown in the figure). The pressing drive module is arranged above the probe module 40 and is used to drive the probe module 40 to move up and down, thereby controlling the contact and separation between the probe 401 and the second contact surface 30121. In other embodiments, a module for controlling the moving up and down of the pressing adapter module 30 may also be provided to facilitate the connection between the battery 20 and the conductive adapter 301.

[0067] In the above embodiments, the end face of the first contact end 3011 of the conductive adapter 301 is a plane, and the first contact end 3011 is pressed against the battery 20 through the plane; in other embodiments, in order to improve the connection stability between the conductive adapter 301 and the battery 20, the end face of the first contact end 3011 may not be a plane. For example, please refer to [link to relevant documentation]. Figure 6 , Figure 6 This is a schematic diagram of another embodiment of the conductive adapter of this application.

[0068] like Figure 6 As shown, in this embodiment, the end face of the first contact end 3011 is a sawtooth surface with equal tooth pitch. The conductive adapter 301 is connected to the battery 20 through the sawtooth, which can increase the pressure at the sawtooth under the same pressure and further improve the connection stability.

[0069] It is understood that in other embodiments, the first contact surface 30113 may not be a sawtooth surface with equal tooth pitch. For example, it may be a sawtooth surface with unequal tooth pitch, or it may be an uneven surface with one or more grooves and / or protruding teeth. All of these can achieve the effect of this embodiment.

[0070] Based on the battery charging and discharging devices of the above embodiments, the arrangement of the conductive adapter 301 provides a larger contact area for the probes 401, which can significantly improve the spacing between the probes 401, avoid the problem of short circuit of the probes 401, and at the same time help improve the connection stability between the probes 401 and the battery 20, reduce the requirements for the positioning accuracy of the probes 401, and make it possible for a pair of probes 401 to be set on different probe modules 410, so as to facilitate the adjustment of the spacing to adapt to different batteries 20 and improve compatibility.

[0071] In addition, the battery charging and discharging equipment can limit the position of the adapter plate 302 through the opening of the tray 10, thereby improving the positional accuracy and stability of the adapter plate 302. The tray 10 is used to achieve precise positioning of the pressing adapter module 30 and the battery 20, reducing the multi-level positioning tolerances that exist in traditional testing.
