[0039] The embodiment of the application provides a pull-out structure, which can slide the probe assembly on the mounting bracket, facilitates the later maintenance of the adjustable probe module by maintenance personnel, reduces the configuration of the maintenance personnel, reduces the maintenance cost, and further reduces the production cost of the battery production test equipment by using the profile to constitute the guide rail.

[0040] The technical solutions of the application will be further described below with reference to the embodiments and the drawings.

[0041] Please refer to Figure 1 , Figure 1 The mounting bracket 200 and the overall structure of the pull-out structure 100 disclosed in the embodiment of the application are shown in the schematic diagram. The embodiment of the application discloses a pull-out structure 100 applied to a battery production test equipment, which comprises a plurality of guide rails 1, a sliding bracket 2 and a plurality of sliding blocks 3. The plurality of guide rails 1 are arranged on the mounting bracket 200, the plurality of guide rails 1 extend along a first horizontal direction a, the plurality of guide rails 1 are arranged in sequence and spaced apart along a second horizontal direction b, and the side surfaces of the adjacent two guide rails 1 close to each other form a sliding groove 11. The guide rail 1 is made of a profile, and the sliding groove 11 is integrally formed with the profile. The sliding bracket 2 is arranged between the adjacent two guide rails 1, and the sliding bracket 2 is used to be connected with the probe assembly. The plurality of sliding blocks 3 are arranged on the two side surfaces of the sliding bracket 2 along the second horizontal direction b, and the plurality of sliding blocks 3 are respectively in sliding cooperation with the sliding grooves 11 on the two sides of the sliding bracket 2.

[0042] Specifically, the formation and capacity equipment plays a key role in lithium battery production, not only activates the chemical properties of the battery, but also ensures the consistency and performance of the battery through accurate testing and sorting. The battery production testing equipment can be one of the formation and capacity equipment, DCIR (Direct Current Internal Resistance) equipment or OCV (Open Circuit Voltage) equipment, which can include a mounting bracket 200 and a probe assembly. The mounting bracket 200 is the entire frame of the formation and capacity equipment. In the embodiments of the present application, the probe assembly is arranged on the sliding bracket 2, and the sliding bracket 2 can realize relative sliding with the mounting bracket 200 through the guide rail 1, so as to facilitate the installation, debugging, maintenance and replacement of the probe assembly, and improve the maintenance efficiency and convenience of the equipment.

[0043] In combination Figure 4 , Figure 4 The schematic diagram of the cooperation structure of two guide rails 1 and one sliding bracket 2 disclosed in the embodiments of the present application is shown. The number of guide rails 1 can be two, and the two guide rails 1 are arranged at intervals along the second horizontal direction b and extend along the first horizontal direction a. The sliding bracket 2 can be clamped in the middle, and the opposite two sides of the sliding bracket 2 along the second horizontal direction b are connected with the sliding blocks 3 of the guide rails 1 respectively. The sliding bracket 2 is connected with the guide rails 1 through the sliding blocks 3. Through this arrangement, the sliding bracket 2 can have bearing capacity on both sides along the second horizontal direction b, so that the sliding of the sliding bracket 2 is more stable.

[0044] The sliding bracket 2 can be a welded frame, and the probe assembly and other components can be installed on the sliding bracket 2 to provide support and fixation for the probe assembly.

[0045] The guide rail 1 can be composed of a profile. The guide rail 1 is composed of a profile, and then cooperates with the sliding block 3 to form a sliding structure. Compared with directly using a drawer slide assembly for sliding connection, the profile has lower cost and is more convenient to process, so that the sliding structure formed by the cooperation of the profile and the sliding block 3 can effectively reduce the cost.

[0046] The sliding groove 11 is integrally formed with the profile, which can fully utilize the characteristics of the profile. The sliding groove 11 can be a groove provided with the profile during forming. Not only can the whole pull-out structure 100 be more simple to process and manufacture, but also the sliding groove 11 has a smoother surface, so that the sliding block 3 can slide more smoothly in the sliding groove 11.

[0047] The number of the sliding blocks 3 is determined according to the number of the guide rails 1, at least one sliding block 3 is arranged in each guide rail 1, the main body of the sliding block 3 slides in the guide rail 1, and the side of the sliding block 3 close to the sliding support 2 is connected with the sliding support 2, so that the sliding support 2 can be connected with the guide rail 1 through the cooperation of the sliding block 3 and the sliding groove 11, and the probe assembly arranged on the sliding support 2 can be conveniently installed, debugged, maintained and replaced by pulling the sliding support 2, and the maintenance efficiency and convenience of the equipment are improved.

[0048] The sliding block 3 can correspond to and be matched with the sliding groove 11 in shape and size, and the sliding block 3 is slidably arranged in the sliding groove 11 and can smoothly slide along the sliding groove 11.

[0049] The sliding block 3 can be made of a non-metal material, so that the manufacturing cost of the sliding block 3 and the entire pull-out structure 100 can be further reduced.

[0050] According to the pull-out structure 100, the probe assembly can be arranged on the sliding support 2, the sliding support 2 is connected with the sliding block 3, the sliding block 3 is slidably arranged in the sliding groove 11 of the guide rail 1, the guide rail 1 is installed on the mounting support 200, the sliding support 2 can slide relative to the guide rail 1 through the sliding cooperation of the sliding block 3 and the sliding groove 11, the relative sliding between the probe assembly and the mounting support 200 is realized, the later maintenance of the adjustable probe module by the maintenance personnel is facilitated, the configuration of the maintenance personnel is reduced, the maintenance cost is reduced, the guide rail 1 is formed by the profile material, compared with the drawer slide rail assembly directly used in the prior art, the profile material not only has low cost but also is convenient to process, the manufacturing cost of the pull-out structure 100 can be reduced, the machining steps of the guide rail 1 can be reduced through the integral forming of the sliding groove 11 and the profile material, the cost can be further reduced, and the machining production efficiency is increased.

[0051] In combination Figure 2 And Figure 3 , Figure 3 The cross-section cooperation structure of the guide rail 1 and the sliding block 3 is shown in the drawings. In some embodiments, the groove bottom 111 of the sliding groove 11 is a concave cylindrical surface, the lower side edge of the sliding groove 11 close to the slot opening 112 has a first flat portion 113;

[0052] The side of the sliding block 3 away from the sliding support 2 is formed with a convex cylindrical surface, the convex cylindrical surface cooperates with the concave cylindrical surface, and the lower side edge of the sliding block 3 has a second flat portion 31 matched with the first flat portion 113.

[0053] Specifically, the concave cylindrical surface of the sliding groove 11 cooperates with the convex cylindrical surface of the sliding block 3. This curved surface cooperation mode can make the sliding block 3 stably slide along a certain trajectory in the sliding groove 11. Compared with the sliding mode of planar contact, the curved surface cooperation can better adapt to the stress change in the sliding process, reduce the sliding block 3 shaking or jamming phenomenon caused by uneven stress, and thus improve the stability of the entire device during operation. Moreover, the contact area of the concave cylindrical surface and the convex cylindrical surface is relatively small. In the sliding process, the contact stress is relatively concentrated, but at the same time, the friction area between the sliding block 3 and the sliding groove 11 is reduced. Smaller friction area means that under the same sliding conditions, the friction force is relatively small, thereby reducing the wear rate of the sliding block 3 and the sliding groove 11 and prolonging the service life of the device. During assembly, the convex cylindrical surface and the concave cylindrical surface can be preliminarily positioned, and then the first flat portion 113 and the second flat portion 31 are used for accurate adjustment, so that the sliding block 3 can be more conveniently and accurately installed to the specified position. Moreover, in the subsequent use process, if it is necessary to adjust the position of the sliding block 3 or the cooperation gap of the device, the relative movement of the sliding block 3 and the sliding groove 11 or the fine adjustment of the flat portion can be used to achieve the adjustment, which is relatively simple and convenient to operate.

[0054] The first flat portion 113 of the sliding groove 11 near the lower side edge of the slot 112 cooperates with the second flat portion 31 of the lower side edge of the sliding block 3. This planar cooperation mode can further limit the position of the sliding block 3 in the sliding groove 11. When the sliding block 3 slides to a certain position, the cooperation of the first flat portion 113 and the second flat portion 31 can prevent the sliding block 3 from being pulled out of the sliding groove 11.

[0055] In combination Figure 2 and Figure 3 In some embodiments, the sliding groove 11 near the upper side edge of the slot 112 has a third flat portion 114, and the upper side edge of the sliding block 3 has a fourth flat portion 32 cooperating with the third flat portion 114.

[0056] Specifically, by cooperating the first flat part 113 with the second flat part 31, and then cooperating the third flat part 114 with the fourth flat part 32, the slider 3 can be subjected to more uniform support force in the sliding groove 11. When the slider 3 is subjected to external force, the upper and lower flat parts can jointly bear and disperse the external force, avoiding the slider 3 from tilting or shaking due to uneven force, thereby enhancing the stability of the slider 3 in the sliding groove 11. This is of great significance to improve the reliability of the device when running at high speed or subjected to greater impact force, and can effectively reduce the failure or damage caused by the instability of the slider 3. Moreover, the slider 3 can also be limited from coming out, and the cooperation of the third flat part 114 and the fourth flat part 32 can restrict the position of the slider 3 in the sliding groove 11, preventing the slider 3 from coming out of the slot opening 112 of the sliding groove 11 due to external force or inertia during sliding. Especially at the slot opening 112 of the sliding groove 11, this cooperation structure can effectively block the slider 3 from sliding out of the sliding groove 11 upward, improving the safety and reliability of the device, avoiding the sliding support 2 from falling due to the slider 3 coming out, and damaging the probe assembly and other equipment.

[0057] In combination Figure 5 , Figure 5 The three guide rails 1 and the two sliding supports 2 disclosed in the embodiments of the present application are shown in the schematic view of the cooperation structure. In some embodiments, the guide rail 1 includes a first surface and a second surface oppositely arranged along the second horizontal direction b, and both the first surface and the second surface are provided with a sliding groove 11.

[0058] Specifically, the sliding groove 11 is arranged on both the first surface and the second surface of the guide rail 1, so that one guide rail 1 can slide the slider 3 on the first surface and the second surface respectively. When multiple sliding supports 2 are needed, adjacent two sliding supports 2 can share one guide rail 1 to save space. For example, when there are two sliding supports 2, the two sliding supports 2 can be arranged in sequence along the second horizontal direction b with a certain interval, and then one side of one sliding support 2 is slidably arranged in the sliding groove 11 on the first surface of the guide rail 1, and one side of the other sliding support 2 is slidably arranged in the sliding groove 11 on the second surface of the guide rail 1, so that one guide rail 1 can provide sliding grooves 11 for two sliding supports 2 on both sides. Compared with arranging two guide rails 1 for each sliding support 2 and arranging four guide rails 1 when there are two sliding supports 2, the embodiments of the present application can achieve the sliding connection of the sliding supports 2 by arranging three guide rails 1 when there are two sliding supports 2, which not only saves materials and reduces costs, but also makes the gap between the sliding supports 2 smaller and the overall pull-out structure 100 more compact, reducing the occupied space.

[0059] In combination Figure 2 , Figure 2A schematic view of the cooperation structure of the guide rail 1 and the sliding block 3 disclosed in the embodiments of the present application. In some embodiments, the number of sliding grooves 11 on the first surface and the second surface is multiple, the multiple sliding grooves 11 are arranged in the vertical direction, and at least one sliding block 3 is arranged in each sliding groove 11.

[0060] Specifically, the number of sliding grooves 11 can be two, the two sliding grooves 11 are parallel to each other and arranged in the vertical direction, and the arrangement of the multiple sliding grooves 11 can disperse the gravity of the sliding support 2, improve the load capacity of the sliding support 2, and effectively improve the service life of the pull-out structure 100.

[0061] In combination Figure 3 In some embodiments, the sliding grooves 11 on the first surface and the sliding grooves 11 on the second surface are arranged staggered in the second horizontal direction b.

[0062] Specifically, the number of sliding grooves 11 arranged on each surface is at least two, and the arrangement of the multiple sliding grooves 11 can make the sliding connection of the sliding support 2 and the guide rail 1 more stable, disperse the gravity of the sliding support 2, improve the load capacity of the pull-out structure 100, make the sliding support 2 can carry more components, and improve the service life of the pull-out structure 100.

[0063] The sliding grooves 11 on the first surface and the second surface are staggered in the second horizontal direction b, which can effectively utilize the longitudinal space on the first surface and the second surface. When there are two sliding grooves 11 on the first surface and the second surface, the sliding groove 11 on the top of the first surface and the sliding groove 11 on the top of the second surface can be staggered, the sliding groove 11 on the top of the first surface can be inserted into the gap between the two sliding grooves 11 on the second surface, which can greatly save space, make the pull-out structure 100 more compact, and also reduce the height of the guide rail 1, reduce the required material of the guide rail 1, and save costs.

[0064] In combination Figure 2 In some embodiments, the guide rail 1 has a mounting hole 4 at both ends in the first horizontal direction a, the mounting hole 4 penetrates the guide rail 1 in the vertical direction, and the mounting hole 4 and the sliding groove 11 penetrate in the vertical direction.

[0065] The pull-out structure 100 further comprises a fastener, the fastener penetrates the mounting hole 4 and is used for being connected to the mounting bracket 200.

[0066] Specifically, the fastener can be a connecting bolt, the connecting bolt passes through the mounting hole 4 and is screwed on the mounting bracket 200, and then the guide rail 1 is mounted on the mounting bracket 200.

[0067] Wherein, since the mounting hole 4 is located at both ends of the guide rail 1 along the first horizontal direction a, the mounting hole 4 is through in the vertical direction with the sliding groove 11, when the connecting bolt passes through the mounting hole 4, the connecting bolt can pass through the sliding groove 11, the connecting bolt can block both ends of the sliding groove 11 along the first horizontal direction a, and the sliding block 3 can be prevented from sliding out of the sliding groove 11 from the first horizontal direction a, causing the sliding bracket 2 to be separated from the guide rail 1, so that the sliding bracket 2 falls and damages the sliding bracket 2 and the probe assembly arranged on the sliding bracket 2, and the sliding bracket 2 can be limited and protected.

[0068] In combination Figure 2 In some embodiments, the sliding block 3 is a long strip extending along the first horizontal direction a.

[0069] Specifically, the long strip-shaped sliding block 3 can make the sliding block 3 have more contact area with the sliding groove 11 and the sliding bracket 2, make the cooperation of the sliding block 3 and the sliding groove 11 more stable, and make the connection of the sliding block 3 and the sliding bracket 2 more stable, so that the sliding bracket 2 has higher bearing capacity and the service life of the pull-out structure 100 is improved.

[0070] In some embodiments, the material of the sliding block 3 is non-metal.

[0071] Specifically, the sliding block 3 can be made of non-metal materials such as engineering plastics, which can further reduce the production cost, reduce the weight, improve the corrosion resistance, avoid damage caused by corrosion, and improve the service life of the pull-out structure 100.

[0073] Specifically, a nut can be arranged in the accommodating portion 121, a screw is screwed on the nut, the screw passes through the connecting portion 122 and extends out of the slot of the mounting groove 12, and then the external component is mounted through the screw, wherein the mounting groove 12 penetrates through the two opposite end faces of the guide rail 1 along the first horizontal direction a, the nut can be conveniently taken in and out of the accommodating portion 121, the nut can be conveniently disassembled and assembled, and before the external component is mounted, the nut can be slid in the first horizontal direction in the accommodating portion 121 by sliding the nut, so as to adjust the specific position of the nut in the accommodating portion 121, so that the nut and the screw can adapt to the installation requirements of different positions and have better adaptability.
