[0048] The present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] The present utility model relates to a multi-channel battery test fixture, which can be used to test multiple batteries simultaneously. The limiting mechanisms 3 are arranged at intervals at the bottom of the frame 1, and a plurality of battery channels for installing batteries can be formed. The limiting mechanisms 3 can slide horizontally to clamp and fix batteries of different specifications. The pressing mechanism 2 can be connected to the electrodes of the batteries through the probe assembly 21 at the top of the frame 1 to test the batteries; a plurality of battery channels are centrally arranged to test multiple batteries simultaneously; the limiting mechanisms 3 can flexibly adjust their spacing to measure batteries of different specifications, solving the problems of low working efficiency and low integration degree in the background technology, and having great popularization value.

[0050] A multi-channel battery test fixture, specifically, as Figures 1 to 7As shown, it includes a frame 1, a pressing mechanism 2 and a limiting mechanism 3. The frame 1 is a hollow structure. Inside the frame 1, there are multiple battery channels for installing batteries. The hollow structure can be used to install batteries, the pressing mechanism 2 and the limiting mechanism 3. The pressing mechanism 2 is arranged at the top of the frame 1, and multiple probe assemblies 21 are provided on the pressing mechanism 2. Preferably, the probe assembly 21 is an elastic telescopic probe assembly 21. Two probe assemblies 21 are in a group and are respectively connected to two electrodes of the battery. The limiting mechanism 3 is slidably arranged on the inner wall of the bottom of the frame 1 in the transverse direction. Multiple limiting mechanisms 3 are arranged at intervals in the transverse direction. The gap between adjacent limiting mechanisms 3 can be used as a battery channel for installing batteries. Multiple limiting mechanisms 3 are arranged at intervals to form multiple battery channels. The limiting mechanism 3 can move laterally flexibly to clamp and fix the battery, with high flexibility, and can realize simultaneous installation and testing of multiple batteries.

[0051] In a certain embodiment, the limiting mechanism 3 is described as follows Figures 2 to 4 As shown, a transverse first sliding groove 111 is provided on the bottom wall of the bottom of the frame 1. The limiting mechanism 3 includes a limiting plate 31 and an adjusting mechanism provided on the limiting plate 31. The limiting plate 31 can slide along the first sliding groove 111. The adjusting mechanism is used to cooperate with the first sliding groove 111 to adjust the sliding and fixing of the limiting plate 31 on the first sliding groove 111. Under the control of the adjusting mechanism, adjacent two limiting plates 31 can move to clamp and fix the battery placed between the two limiting plates 31, and the battery clamp is laterally limited and fixed on the frame 1 by fixing adjacent two limiting plates 31 through the adjusting mechanism.

[0052] Based on the fact that the limiting mechanism 3 includes a limiting plate 31 and an adjusting mechanism, as Figures 2 to 4 shown, in a certain embodiment, the adjusting mechanism includes a limiting slider 32 and an adjusting rod 33 provided on one side of the first sliding groove 111. An adjusting hole 311 is provided on the limiting plate 31. One end of the adjusting rod 33 passes through the adjusting hole 311 and is threadedly connected to the limiting slider 32 through the first sliding groove 111, and the other end is provided with a limiting block. The adjusting rod 33 is preferably a wing bolt, which is convenient for manual adjustment. The structure of this adjusting mechanism is simple and easy to use. Align the adjusting hole 311 of the limiting plate 31 with the first sliding groove 111, and after passing the adjusting rod 33 through the adjusting hole 311 and the first sliding groove 111 in sequence and then bolting the limiting slider 32, the limiting plate 31 can be fastened on the frame 1. Loosening the adjusting rod 33 can make the limiting plate 31 slide laterally.

[0053] Based on the fact that the limiting mechanism 3 includes a limiting plate 31 and an adjusting mechanism, as Figures 2 to 4As shown in the figure, the limit slider 32 includes a limit protrusion inserted into the first chute 111 and slidable along the first chute 111. The limit slider 32 is located on one side of the first chute 111 and is vertically limited by the first chute 111. Preferably, the first chute 111 is a T-shaped chute, and the limit slider 32 is a T-shaped structure adapted to the first chute 111. Both the first chute 111 and the limit slider 32 are inverted T-shaped structures. When the rotation adjusting rod 33 is bolted to the limit slider 32, the inverted T-shaped limit slider 32 is limited by the first chute 111 and cannot rotate, which is beneficial to tightening and loosening the adjusting rod 33, and avoids the limit slider 32 rotating when the adjusting rod 33 is rotated and the limit plate 31 cannot be fastened to the bottom of the frame 1; in addition, it can also make the bottom surface of the frame 1 flat.

[0054] Based on the limit mechanism 3 including the limit plate 31 and the adjusting mechanism, as Figure 2 or Figure 4 shown in the figure, a plurality of parallel first chutes 111 are provided at the bottom of the frame 1, and a plurality of adjusting holes 311 corresponding to the first chutes 111 are provided on the limit plate 31; a plurality of adjusting mechanisms fasten the limit plate 31 to the bottom of the frame 1 corresponding to the adjusting holes 311; preferably, two first chutes 111 are provided, and adjusting holes 311 are provided at both ends of the limit plate 31. Two adjusting mechanisms fasten both ends of the limit plate 31 to the frame 1 through the two adjusting holes 311 and the first chutes 111 respectively. Through the plurality of first chutes 111 and the corresponding limit plate 31 and adjusting mechanisms, the offset of the limit plate 31 during the sliding process can be avoided. The plurality of adjusting mechanisms passing through the adjusting holes 311 and the first chutes 111 can play a guiding role, enabling the limit plate 31 to slide horizontally, thereby accurately fixing the orientation of the battery and avoiding the two electrodes of the battery not being able to completely align with the contact probe assembly 21.

[0055] In some embodiments, as Figure 1 、 Figure 2 、 Figure 4 and Figure 6 shown in the figure, multiple groups of probe assemblies 21 are longitudinally slidably arranged on the pressing mechanism 2, which can solve the problem that the positions of the electrodes of different specifications of batteries are different. The limit structure can horizontally move to adjust the position of the battery, and the longitudinal sliding of the probe assemblies 21 can make them align with the electrodes of different specifications of batteries to achieve contact, with higher versatility.

[0056] In some embodiments, as Figures 1 to 2 、 Figures 5 to 6As shown, the pressing mechanism 2 includes a fixed beam 22 and a telescopic device 23. The fixed beam 22 is fixedly connected to the top of the frame 1. The telescopic device 23 is fixed on the fixed beam 22 and can be telescopically extended vertically. The probe assembly 21 is arranged at the telescopic end of the telescopic device 23, and the probe assembly 21 moves and contacts the electrode of the battery when the telescopic device 23 extends and retracts vertically. Preferably, a universal quick clamp is used as the telescopic device 23. An installation hole 222 is provided on the fixed beam 22, and the telescopic end of the universal quick clamp passes through the installation hole 222 and is fixedly connected to the fixed beam 22.

[0057] As Figures 4 to 6 shown, based on the pressing mechanism 2 including the fixed beam 22 and the telescopic device 23, the pressing mechanism 2 further includes a mounting plate 24. The mounting plate 24 is fixedly connected to the telescopic end of the telescopic device 23. A longitudinal second sliding groove 241 is provided on the mounting plate 24, and the probe assembly 21 is arranged in the second sliding groove 241 and can slide longitudinally. Two probe assemblies 21 in a group can share one second sliding groove 241, or two second sliding grooves 241 can be provided to slidably mount the two probe assemblies 21 respectively.

[0058] Based on the mounting plate 24 being provided with the second sliding groove 241, as Figure 6 shown, a first guiding groove 242 parallel to it is provided on one side of the second sliding groove 241. The probe assembly 21 is fixedly provided with a guiding sliding plate 211, and a first guiding sliding column 2112 is provided on the guiding sliding plate 211. The first guiding sliding column 2112 is located in the first guiding groove 242 and can slide axially along the first guiding groove 242, which is used to guide the longitudinal sliding of the probe assembly 21 and prevent it from deviating during sliding and being unable to contact the battery electrode. Preferably, the first guiding groove 242 is provided on both sides of the second sliding groove 241. The first guiding sliding columns 2112 are correspondingly provided on the guiding sliding plate 211 for the two first guiding grooves 242, and the probe assembly 21 is arranged between the two first guiding grooves 242. The stability of the longitudinal sliding of the probe assembly 21 can be further improved through the two first guiding grooves 242.

[0059] Based on the pressing mechanism 2 including the fixed beam 22 and the telescopic device 23, in a certain embodiment, as Figures 1 to 2 and Figures 4 to 5 shown, the frame 1 includes a bottom plate 11 and vertical plates 12 fixed on both sides of the bottom plate 11. Both ends of the fixed beam 22 are respectively slidably arranged vertically on the two vertical plates 12, so that the fixed beam 22 is fixedly arranged at the top of the frame 1 with adjustable height, that is, the height of the pressing mechanism 2 is adjusted to adapt to testing batteries of different specifications, and the versatility of this battery testing fixture is improved.

[0060] Based on both ends of the fixed beam 22 being respectively slidably arranged vertically on the two vertical plates 12, as Figure 1 and Figure 4As shown, in an embodiment, the vertical plate 12 is provided with an adjusting and fixing component for cooperating with the fixed beam 22; the adjusting and fixing component includes a vertical fourth chute 121 provided on the vertical plate 12, a pressing willow stud 221 provided at the end of the fixed beam 22, and a bolting member that passes through the fourth chute 121 and is threadedly connected inside the pressing willow stud 221. In use, tightening the bolting member can fix the end of the fixed beam 22 on the vertical plate 12; when measuring batteries of different specifications, when the adjustable distance of the pressing mechanism 2 does not meet the requirements, the height of the fixed beam 22 can be adaptively adjusted so that the probe assembly 21 of the pressing mechanism 2 can contact the battery electrode.

[0061] In a preferred embodiment, the vertical movement of the mounting plate 24 is optimized, such as Figures 1 to 2 and Figure 4 As shown, the frame 1 includes a bottom plate 11 and vertical plates 12 fixed on both sides of the bottom plate 11; the end of the mounting plate 24 is provided with a guiding structure for cooperating with the vertical plates 12 to provide a guiding function when the mounting plate 24 moves vertically. Specifically, both ends of the mounting plate 24 are vertically slidably arranged on the two vertical plates 12 respectively. The guiding structure includes vertical second guiding grooves 122 arranged in parallel on the mounting plate 24 and second guiding sliding columns 243 arranged at the end of the mounting plate 24. The second guiding sliding columns 243 are located in the second guiding grooves 122 and can slide axially along the second guiding grooves 122. Preferably, the second guiding grooves 122 and the second guiding sliding columns 243 are correspondingly distributed at the four corners of the mounting plate 24. More preferably, there is a gap between the end face of the mounting plate 24 and the corresponding vertical plate 12 to prevent resistance and noise generated by friction between the mounting plate 24 and the vertical plate 12 during the sliding process. The second guiding sliding columns 243 and the second guiding grooves 122 can provide a guiding function for the vertical movement of the mounting plate 24, avoiding tilting or deviation during movement, which may cause the probe assembly 21 not to contact the battery electrode.

[0062] On the basis that a transverse first chute 111 is provided on the bottom of the frame 1, in an embodiment, such as Figure 1 and Figure 4 As shown, an insulating layer 4 is provided on the bottom wall of the inner cavity at the bottom of the frame 1, and the insulating layer 4 is provided with a third chute 41 corresponding to the first chute 111 and communicating with the first chute 111. In use, the limiting plate 31 is arranged on the insulating layer 4, and the adjusting mechanism fixes the limiting plate 31 on the insulating layer 4 in a horizontally slidable manner through the overlapping first chute 111 and third chute 41. The insulating layer 4 can improve the safety of the present invention and avoid potential safety hazards caused by contact between the battery and the frame 1.

[0063] During actual use, such as Figure 7As shown, place multiple batteries between the limiting plates 31, and try to position the batteries directly below the corresponding set of probe assemblies 21. Loosen the adjusting rods 33 of the limiting mechanisms 3 on both sides of the electrical measurement, slide the limiting plates 31 horizontally until they abut against the batteries, and then tighten the adjusting rods 33 to fasten the limiting plates 31 to the bottom plate 11, thereby fixing the batteries on the bottom plate 11. Slide the probe assemblies 21 longitudinally to position them above the battery electrodes, tighten the universal quick clamp to vertically move the probe assemblies 21 to contact the battery electrodes. During this process, the positions of the limiting plates 31 for fixing the batteries and the probe assemblies 21 can be adjusted as needed, so that the probe assemblies 21 move vertically downward to contact the battery electrodes, and then the battery tests can be carried out.
