Description

Technical Field

[0001] This utility model relates to the field of battery measurement, and in particular to a battery holder for testing cylindrical batteries. Background Technology

[0002] Batteries are indispensable in people's lives, and cylindrical batteries are among the most common. Before being sold, it is essential to test the electrical parameters of cylindrical batteries, providing crucial considerations for safety assessment, performance verification, quality control, and compliance with standards. One existing measurement method involves assembling the cylindrical battery in a battery holder and then taking out corresponding electrodes to measure voltage and internal resistance. However, in practical use, the method of detaching the battery holder from the cylindrical battery is rather simplistic. A battery slot is created in the battery holder, with electrode plates formed at both ends. The battery is then assembled in the slot. Because the slot covers a large area of ​​the battery, disassembly is inconvenient, often requiring tools to pry it open. Furthermore, the excessive enclosure of the cylindrical battery by the slot hinders heat dissipation during testing, leading to inaccurate internal resistance measurements. Therefore, a more structurally sound battery holder is urgently needed to solve these technical problems. Utility Model Content

[0003] In view of the fact that the battery slot structure of the existing battery holder is not very reasonable, which makes the disassembly of the cylindrical battery more complicated and is not conducive to the heat dissipation of the cylindrical battery, this utility model provides a solution.

[0004] To achieve the above objectives, this utility model provides a battery holder for testing cylindrical batteries, comprising a main body, the top surface of which is provided with a battery groove for mounting a cylindrical battery, and two opposite inner end faces of the battery groove are respectively provided with a first conductive element and a second conductive element, the first conductive element and the second conductive element being used to make elastic contact with the cylindrical battery; the two outer walls of the main body are also provided with notches communicating with the battery groove.

[0005] As an improvement of this application, when the cylindrical battery is assembled, there is a gap between the two opposing inner walls of the battery slot and the cylindrical battery.

[0006] As an improvement of this application, the bottom surface of the battery slot is an arc surface, and arc-shaped strips are provided on both opposite sides of the bottom surface of the slot.

[0007] As an improvement to this application, the bottom surface of the groove is also provided with an elongated hole.

[0008] As an improvement of this application, the bottom surface of the main body is further provided with raised feet, the raised feet being the installation spacing formed by the bottom surface of the main body.

[0009] As an improvement of this application, the profile of the main body forming the notch is arc-shaped.

[0010] As an improvement of this application, the notch extends to both ends of the main body, and the distance from the arc center to the bottom surface of the main body accounts for 1 / 3 to 4 / 5 of the height of the end face of the main body.

[0011] As an improvement of this application, the two opposite end faces of the battery slot are provided with insertion slots for corresponding assembly of the first conductive element and the second conductive element.

[0012] As an improvement of this application, the first conductive member and the second conductive member are further provided with hook portions on their opposite sides, and the inner wall of the insertion groove is provided with a snap groove for the hook portions to engage.

[0013] As an improvement of this application, the first conductive element and the second conductive element are metal springs and / or metal shrapnel.

[0014] The beneficial effects of this utility model are as follows: Compared with the prior art, the battery holder for testing cylindrical batteries provided by this utility model includes a main body. The top surface of the main body is provided with a battery groove for installing cylindrical batteries. The two opposite inner end faces of the battery groove are respectively provided with a first conductive element and a second conductive element, which are used to make elastic contact with the cylindrical battery. The two outer walls of the main body are also provided with notches that communicate with the battery groove. First, the battery is initially positioned by the battery groove. Then, the two ends of the cylindrical battery are elastically squeezed and fixed by the first conductive element and the second conductive element, so that the cylindrical battery can be stably fixed in the battery groove and achieve electrical contact. Furthermore, notches are provided on both sides of the battery groove to expose the cylindrical surface of the cylindrical battery in the assembled state, thereby facilitating technicians to grasp and remove the battery, and realizing the quick removal and installation of the battery.

[0022] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0023] In the following description, specific examples are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0024] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0025] To address the aforementioned technical problems, this application provides a battery holder for testing cylindrical batteries. Please refer to the appendix. Figure 1 To be continued Figure 4 The device includes a main body 1, the top surface of which is provided with a battery slot 2 for mounting a cylindrical battery. The two opposite inner end faces of the battery slot 2 are respectively provided with a first conductive element 3 and a second conductive element 4, which are used to make elastic contact with the cylindrical battery. The two outer walls of the main body 1 are also provided with notches 5 that communicate with the battery slot 2.

[0026] It is easy to understand that the user first positions the battery in the battery slot 2, and then uses the first conductive component 3 and the second conductive component 4 to elastically squeeze and fix the two ends of the cylindrical battery, so that the cylindrical battery can be stably fixed in the battery slot 2 and achieve electrical contact. Furthermore, notches 5 are provided on both sides of the battery slot 2 to expose the cylindrical surface of the assembled battery, which makes it easier for technicians to grasp and remove the battery, thus enabling the battery to be quickly removed and installed.

[0027] As can be seen, the cylindrical battery is fixed by the elastic effect of the first conductive element 3 and the second conductive element 4, and the cylindrical battery is reduced by the corresponding notches 5 on both sides of the battery slot 2. The user can apply force to the cylindrical surface of the cylindrical battery when taking it out, making it easier to remove the cylindrical battery. The notches 5 expose the cylindrical surface of the cylindrical battery, achieving more efficient heat dissipation.

[0028] In the specific design, when the cylindrical battery is assembled, there is a gap between the two opposing inner walls of the battery slot 2 and the cylindrical battery. It is easy to understand that with this width design, the cylindrical battery has less contact with the inner wall of the battery slot 2, and it is less likely to get stuck when it is removed.

[0029] In this embodiment, the bottom surface of the battery slot 2 is curved, and arc-shaped strips 21 are provided on both opposite sides of the bottom surface. Setting the bottom surface of the slot as curved can better fit the structural shape of the cylindrical battery and achieve more stable placement. The arc-shaped strips 21 combined with the notch allow technicians to have more space to remove the battery, further facilitating the user's removal operation. At the same time, the arc-shaped strips 21 and the notch also increase the exposed area of ​​the cylindrical battery, resulting in better heat dissipation. As an improvement of this embodiment, the profile of the main body 1 forming the notch is arc-shaped, which effectively increases the exposed area of ​​the cylindrical battery during operation and further improves the heat dissipation effect.

[0030] To further enhance heat dissipation performance, in this embodiment, the bottom surface of the slot is also provided with elongated holes 22.

[0031] In this embodiment, the bottom surface of the main body 1 is also provided with a raised foot 11, and the raised foot 11 forms an installation distance with the bottom surface of the main body 1. It is easy to understand that the raised foot 11 enables the main body 1 to be suspended on the plane, and the installation distance can be connected with the elongated hole 22, so as to further enhance the heat dissipation performance.

[0032] In this embodiment, the notch extends to both ends of the main body 1, and the distance from the arc center to the bottom surface of the main body 1 accounts for 1 / 3-4 / 5 of the height of the end face of the main body 1. Under this size design, it has the three characteristics of cylindrical battery installation stability, quick removal and heat dissipation.

[0033] In this embodiment, the two opposite end faces of the battery slot 2 are provided with insertion slots 23 for corresponding assembly of the first conductive component 3 and the second conductive component 4. By setting the insertion slots 23 to connect with the first conductive component 3 and the second conductive component 4, the assembly of the components is facilitated. In a further embodiment, the opposite side of the first conductive component 3 and the second conductive component 4 is also provided with a hook portion 6. The inner wall of the insertion slot 23 is provided with a latching groove for the hook portion 6 to engage. The latching groove and the hook portion 6 can significantly improve the installation firmness of the first conductive component 3, the second conductive component 4 and the main body 1, so that when the cylindrical battery is pulled out, the first conductive component 3 or the second conductive component 4 will follow. In a specific embodiment, the first conductive component 3 and the second conductive component 4 are made of conductive metal, conductive silicone, etc. In a preferred embodiment, the first conductive component 3 and the second conductive component 4 are metal springs and / or metal springs, which have stable processes, low costs, and are easy to replace.

[0034] The advantages of this utility model are:

[0035] 1. When the cylindrical battery is assembled, there is a gap between the two opposite inner walls of the battery compartment and the cylindrical battery; it is easy to understand that with this width design, the cylindrical battery has less contact with the inner wall of the battery compartment, and it is less likely to get stuck when it is removed.

[0036] 2. The notch extends to both ends of the main body, and the distance from the center of the arc to the bottom surface of the main body accounts for 1 / 3-4 / 5 of the height of the end face of the main body. Under this size design, it has the three characteristics of cylindrical battery installation stability, quick removal and heat dissipation.

[0037] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
