Description

Technical Field

[0001] This utility model relates to the field of electrical product testing technology, and in particular to an electrical product temperature rise testing device. Background Technology

[0002] When a battery is overcharged, over-discharged, short-circuited, or charged and discharged at high rates, the internal chemical reaction intensifies, causing the temperature to rise sharply. Temperature rise detection can be used to detect and determine the temperature conditions under which different types of batteries will react violently.

[0003] The prior art, as disclosed in Chinese Patent Publication No. CN219871589U, is a battery temperature detection device, relating to the field of battery testing technology. It includes an outer casing with an inner casing fixed inside. An inner cover plate is provided on the top of the inner casing, and bolts are inserted into each of the four corners of the inner cover plate. One end of each bolt passes through the inner cover plate and is threaded to the top four corners of the inner casing. Temperature detectors are provided at both ends of the inner casing. This application utilizes a heating rod to generate heat after operation. This heat can propagate within the outer casing, creating a heated space within the casing formed by the inner casing and the inner cover plate. The temperature detectors determine the temperature value within this heated space, matching it to the temperature value in hot weather. This simulates the working environment of a battery installed inside a vehicle shell under hot temperatures. The temperature detectors within the inner casing detect the internal temperature value, ensuring the accuracy and authenticity of the temperature detection data during battery power transmission.

[0004] In practical operation, considering that the battery is fixed inside the box, and the battery cannot be rotated, it is easy to cause inconsistent chemical reaction rates inside the battery, which affects the measurement of key parameters such as internal resistance and capacity, resulting in poor practicality. Summary of the Invention

[0005] The purpose of this invention is to solve the shortcomings of the existing technology, such as the battery being fixed and unable to be rotated, resulting in uneven heating, and to propose an electrical product temperature rise testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design an electrical product temperature rise testing device, including a housing, inside which a plurality of drive rollers and a plurality of movable rollers are rotatably connected, the drive rollers and the movable rollers are arranged alternately, and a battery is placed between two adjacent drive rollers and movable rollers; Among them, a plurality of drive rollers rotate synchronously through a drive assembly, a plurality of movable rollers are slidably connected to the housing, and an adjustment assembly is connected between the plurality of movable rollers, the adjustment assembly being used to adjust the distance between the movable rollers and the drive rollers on the adjacent side; The adjustment assembly includes a drive rod, and an anti-accidental contact structure is provided between the drive rod and the housing.

[0007] Furthermore, the side of the housing is provided with an installation cavity and a sealing cover for closing the installation cavity, wherein the inner wall of the installation cavity is provided with a groove between two adjacent drive rollers, and the end of the movable roller is slidably connected in the groove.

[0008] Furthermore, the adjustment assembly also includes a connecting rod and a cross plate. The middle part of the connecting rod is rotatably connected to the inner wall of the mounting cavity via a shaft, and the two ends of the connecting rod are rotatably connected to the end of the movable roller shaft and the bottom of the cross plate, respectively.

[0009] Furthermore, a rack is fixedly connected to the top of the horizontal plate, and the rack meshes with a gear for transmission. One end of the drive rod passes through the sealing cover and is fixedly connected to the gear. A shaft seal is provided between the shaft end of the drive rod and the sealing cover.

[0010] Furthermore, the anti-accidental touch structure includes a pair of latching members, which are sleeved around the end of the drive rod, and the pair of latching members are also locked to each other by the interlocking of the latching grooves and protrusions on opposite sides.

[0011] Furthermore, one of the snap-fit ​​components is fixedly connected to the end face of the sealing cover and rotatably connected to the drive rod, while the other snap-fit ​​component is slidably connected to the drive rod through a limiting part; The drive rod has a handwheel and a compression spring fixedly connected to its end. The two ends of the compression spring abut against the handwheel and the snap-fit ​​member on the adjacent side, respectively.

[0012] The present invention provides an electrical product temperature rise testing device with the following advantages: The present invention uses an adjusting component to drive several movable rollers to move synchronously, thereby adjusting the distance between the movable rollers and the adjacent drive roller. This allows the drive rollers and movable rollers to support circular batteries of different diameters within a certain range, and also drives the batteries to rotate, ensuring that the batteries are not heated unevenly on one side during the heating process. Furthermore, the adjusting component has an anti-accidental contact structure between the drive rod and the sealing cover. By unlocking or fixing the locking components, a pair of locking components can be separated or joined, preventing accidental contact of the drive rod from causing changes in the position of the movable rollers and thus avoiding affecting the normal heating of the battery.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 An electrical product temperature rise testing device includes a housing 1, inside which a plurality of drive rollers 2 and a plurality of movable rollers 3 are rotatably connected, the drive rollers 2 and the movable rollers 3 are staggered, and a battery is placed between two adjacent drive rollers 2 and movable rollers 3. Among them, several drive rollers 2 rotate synchronously through drive assembly 4, several movable rollers 3 are slidably connected to the housing 1, and each of the movable rollers 3 is connected to an adjustment assembly 5, which is used to adjust the distance between the movable roller 3 and the drive roller 2 on the adjacent side; The adjustment component 5 includes a drive rod 51, and an anti-accidental contact structure 6 is provided between the drive rod 51 and the housing 1.

[0017] In some embodiments, such as Figure 2 As shown, the drive assembly 4 includes gears, racks and motors. The gears are fixedly connected to the end of the drive roller 2 and the end of the motor shaft. A rack is sleeved between several gears through a tensioning wheel.

[0018] It is worth mentioning that the surface of the drive roller 2 is provided with anti-slip texture, while the surface of the movable roller 3 is smooth. The circular battery is engaged between the drive roller 2 and the movable roller 3. Under the action of the anti-slip texture and with the support of the movable roller 3, the battery is driven to rotate. The way in which the drive roller 2 and the movable roller 3 drive the battery to rotate can be referred to the structure of the sausage roasting machine in the prior art. Of course, multiple heating units and temperature sensing units are installed inside the housing 1. Both the heating units and the temperature sensing units are connected to the control terminal. The specific connection method is existing technology and will not be described in detail here.

[0019] Furthermore, the side of the housing 1 is provided with a mounting cavity 11 and a sealing cover 12 for closing the mounting cavity 11. The inner wall of the mounting cavity 11 is provided with a groove 13 between two adjacent drive rollers 2, and the end of the movable roller 3 is slidably connected in the groove 13.

[0020] Furthermore, the adjustment assembly 5 also includes a connecting rod 52 and a horizontal plate 53. The middle part of the connecting rod 52 is rotatably connected to the inner wall of the mounting cavity 11 via a shaft, and the two ends of the connecting rod 52 are rotatably connected to the shaft end of the movable roller 3 and the bottom of the horizontal plate 53, respectively.

[0021] More specifically, a rack 54 is fixedly connected to the top of the horizontal plate 53, and the rack 54 meshes with the gear 55 for transmission. One end of the drive rod 51 passes through the sealing cover 12 and is fixedly connected to the gear 55. A shaft seal is provided between the shaft end of the drive rod 51 and the sealing cover 12.

[0022] In this embodiment, as Figure 3 As shown, the middle part of the connecting rod 52 is rotatably connected to the inner wall of the mounting cavity 11. When the handwheel drives the drive rod 51 to rotate, the gear 55 rotates synchronously. Under the drive of the gear 55, the rack 54 drives the horizontal plate 53 to move laterally. During the lateral movement, the connecting rod 52 drives several movable rollers 3 to slide in the opposite direction of the movement of the horizontal plate 53. Specifically, because the drive roller 2 and the movable roller 3 are staggered, the movable roller 3 can adjust the distance between itself and the adjacent drive roller 2 by sliding. The bottom half of the battery is placed between the drive roller 2 and the movable roller 3 to prevent the center of gravity from being unstable and causing the rotation to shift.

[0023] More specifically, friction between the movable roller 3 and the chute 13 can be reduced by a slider. Also, the sealing cover 12 and the mounting cavity 11 can be sealed by a sealing gasket to prevent a large amount of hot air from leaking out.

[0024] In general, the anti-accidental touch structure 6 includes a pair of latching members 61, which are sleeved around the end of the drive rod 51, and the pair of latching members 61 are also locked to each other by the interlocking of the latching grooves and protrusions on opposite sides.

[0025] Finally, one of the snap-fit ​​pieces 61 is fixedly connected to the end face of the sealing cover 12 and rotatably connected to the drive rod 51, while the other snap-fit ​​piece 61 is slidably connected to the drive rod 51 through the limiting part 62. The drive rod 51 is fixedly connected to a handwheel and a compression spring 63. The two ends of the compression spring 63 abut against the handwheel and the snap-fit ​​member 61 on the adjacent side, respectively.

[0026] In this embodiment, as Figure 5 As shown, one of the latching parts 61 moves toward the other latching part 61 under the action of the compression spring 63. Because a limiting part 62 is provided between the slidable latching part 61 and the drive rod 51, the pair of latching parts 61 can be locked by the interlocking of the latching grooves and protrusions at opposite ends. Specifically, the limiting part 62 is a limiting key and a limiting groove. The limiting key is fixedly connected to the end of the drive rod 51. The slidable snap-fit ​​part 61 is provided with a limiting groove on the inner wall of the shaft hole. The limiting groove is slidably connected to the limiting key. More specifically, by pulling the slidable latch 61 outward, the pair of latches 61 can be separated to rotate the drive rod 51.

[0027] Working method: During operation, the distance between the drive roller 2 and the movable roller 3 is adjusted within a certain range according to the size of the round battery; Pull the locking piece 61 to make it slide. When a pair of locking pieces 61 separate, the drive rod 51 can be rotated. The drive rod 51 drives the gear 55 to rotate synchronously. Under the drive of the gear 55, the rack 54 drives the horizontal plate 53 to move laterally. During the lateral movement, the connecting rod 52 drives several movable rollers 3 to slide in the opposite direction of the movement of the horizontal plate 53, so as to adjust the distance between the drive roller 2 and the movable roller 3. Then, the locking member 61 is reset under the action of the compression spring 63, and a pair of locking members 61 engage and lock each other, which can prevent the drive rod 51 from rotating. Finally, the battery is placed between the drive roller 2 and the movable roller 3. The drive roller 2 drives the battery to rotate and heat through the surface protective texture and the supporting effect of the movable roller 3.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
