Description

Technical Field

[0001] The utility model relates to the technical fields of battery adaptation and electrical connection, and in particular to a battery conversion cylinder based on a metal elastic sheet structure. Background Art

[0002] A battery converter is a device that allows different models of batteries to be compatible with each other.

[0003] For example: when the required model of battery is difficult to find or expensive in the market, the battery converter allows the use of more common and cheaper batteries for replacement. Some devices can be compatible with multiple battery models. The battery converter enables users to switch between different models of batteries, improving the flexibility of battery use.

[0004] However, in the prior art, the installation and fixation of the battery conversion structure usually rely on glue and spring structures.

[0005] This traditional method has the following problems:

[0006] 1. Complicated installation and cumbersome operation: The traditional conversion structure requires the use of glue to fix between the battery and the conversion cylinder, and an additional spring structure is needed to ensure the stability of the battery. This method not only increases the installation steps, but also easily causes problems such as uneven application of glue or improper installation of the spring during the actual operation process, resulting in insecure installation or unsatisfactory effects.

[0007] 2. High cost: The use of glue and springs not only increases the cost of production materials, but also increases the time and labor costs during the assembly process. Especially the use of glue also requires maintaining certain environmental conditions during the production process to ensure the stable performance of the glue, thereby further increasing the production cost.

[0008] 3. Poor heat dissipation performance: Since the traditional conversion structure does not consider heat dissipation channels in the design, the heat generated by the battery during operation cannot be effectively dissipated, resulting in an increase in the battery temperature, affecting its performance and service life. In some high-power application scenarios, the heat dissipation problem is particularly prominent, which may cause the battery to overheat and even pose safety hazards.

[0009] 4. Unstable electrical connection: Due to the inherent characteristics of glue and springs, loosening or poor contact is likely to occur during the fixation and contact of the battery, especially in the case of long-term use or being subjected to vibration and impact, this problem is more obvious, seriously affecting the electrical connection stability and overall performance of the battery.

[0010] To solve the above problems, the following improvement methods are usually adopted in the industry:

[0011] 1. Improve the formula and application method of the glue: Use high-performance glue and automated glue application equipment to improve the stability and reliability of installation. However, this method still cannot completely solve the problems of complex installation process and poor heat dissipation performance.

[0012] 2. Introduce a new spring structure: Optimize the spring design to improve the stability of battery fixation and the reliability of electrical connection. However, in practical applications, it is found that the spring structure still has problems such as high cost, easy wear, and performance degradation after long-term use.

[0013] 3. Add heat dissipation materials or heat sinks: Add heat dissipation materials or heat sinks in the conversion structure to improve the heat dissipation effect of the battery. However, this will increase the weight and volume of the product, affecting its portability and ease of use.

[0014] Therefore, how to simplify the installation process, reduce costs, and improve heat dissipation performance and the stability of electrical connection has become the technical problems to be solved by this utility model. Content of the Utility Model

[0015] The technical problem solved by this utility model is to provide a battery conversion cylinder based on a metal elastic sheet structure to solve the problems of complex installation, high cost, poor heat dissipation performance, and unstable electrical connection in the above-mentioned background technology, aiming at the defects existing in the above-mentioned prior art.

[0018] The metal elastic sheet includes a cover and a conductive sheet fixedly connected to the cover. The conductive sheet is fixedly connected to one side of the cover, and there is an included angle of 15 degrees to 40 degrees between the conductive sheet and the cover.

[0019] The top of the conversion cylinder body has a clamping hole, and two vertical cutting holes penetrating the front side and the rear side of the conversion cylinder body are arranged at a position near the top of the side of the conversion cylinder body. The vertical cutting holes are communicated with the clamping hole.

[0020] The metal elastic sheet includes a bent deformation state when it is inserted into the conversion cylinder body and a natural opening state after it enters the conversion cylinder body. When the metal elastic sheet is in the bent deformation state, the metal elastic sheet is inserted into the vertical cutting hole and enters the clamping hole. When the metal elastic sheet is in the natural opening state, after entering the clamping hole, the bent deformation state of the metal elastic sheet is released and it returns to the natural opening state to be clamped and connected with the top of the conversion cylinder body.

[0021] As a further solution of the utility model, the cover includes an outer end surface, the outer end surface of the cover has a raised portion and an annular plane portion arranged around the raised portion, the maximum diameter of the annular plane portion is larger than the diameter of the card hole, the middle part of the raised portion has a circular plane, and the diameter of the circular plane is smaller than the diameter of the card hole.

[0022] As a further solution of the utility model, the conductive sheet and the cover are an integrated structure.

[0023] As a further solution of the utility model, on the cover, there is a bevel transition between the annular plane part and the circular plane.

[0024] As a further solution of the present invention, the conversion cylinder body is made of plastic material.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] 1. Convenient and quick installation method: The utility model uses a vertical cut-in hole designed on the side of the conversion cylinder body, so that the metal spring can be inserted along the vertical cut-in hole in a bent and deformed state, and after insertion, the metal spring can be restored to a straight position by its elasticity, so as to easily achieve a snap-in connection. This design simplifies the installation process and improves user experience and operating efficiency.

[0027] 2. No glue and spring structure, reducing costs: The utility model avoids the metal springs and glue used in the traditional conversion structure, and adopts an integrated metal shrapnel and cover structure, which not only reduces the production materials and process steps, but also reduces the production and maintenance costs.

[0028] 3. Enhanced heat dissipation performance: Through the transparent design of the vertical cut-in hole and the card hole, the heat dissipation channel of the conversion cylinder is effectively increased, and the heat dissipation effect of the battery during operation is improved. This is of great significance to improving the service life and safety of the battery.

[0029] 4. Stable and reliable electrical connection: The utility model uses the angle deformation between the metal spring and the cover to hold the battery, ensuring that the battery has a stable contact after installation. The 15-40 degree angle design between the conductive sheet and the cover makes the battery contact more stable and reliable, thereby improving the stability and performance of the electrical connection.

[0043] Embodiment 1:

[0044] This embodiment provides a battery conversion cylinder based on a metal elastic sheet structure. Through the vertical cutting holes 8 designed on the side of the conversion cylinder body 1, the metal elastic sheet 3 can be inserted along the vertical cutting holes 8 in the bent deformation state and restored to a flat position by the elasticity of the metal elastic sheet 3 after insertion, so as to easily achieve the clamping connection. The specific implementation method is as follows:

[0045] First, a conversion cylinder body 1 is provided, which is made of plastic material and has a bottom open end 2 and a metal spring connection end at the top for clamping a metal spring 3. The top of the conversion cylinder body 1 has a clamping hole 7, and the side near the top is provided with two vertical cut-in holes 8 that penetrate the front and rear sides of the conversion cylinder body 1, and the vertical cut-in holes 8 are connected to the clamping hole 7.

[0046] The metal spring 3 includes a cover 4 and a conductive sheet 5 fixedly connected to the cover 4. The conductive sheet 5 is fixedly connected to one side of the cover 4, and an angle 6 of 15 to 40 degrees is formed between the conductive sheet 5 and the cover 4. During the installation process, the user bends the metal spring 3 into a deformed state, and inserts it into the conversion cylinder body 1 along the vertical cut-in hole 8 until the metal spring 3 enters the clamping hole 7. When the metal spring 3 enters the clamping hole 7, the deformation state of the spring is released, and it is restored to a straight state by its own elasticity, so that it is clamped and connected with the top of the conversion cylinder body 1 to complete the installation.

[0047] In actual operation, this design significantly simplifies the installation process. No glue or spring is needed, and a stable connection can be achieved by simply inserting the metal spring 3 into the conversion cylinder body 1. At the same time, since the use of glue and spring is avoided, not only the production materials and process steps are reduced, but also the production and maintenance costs are reduced.

[0048] The transparent design of the vertical cut-in hole 8 and the clamp hole 7 effectively increases the heat dissipation channel of the conversion cylinder, improving the heat dissipation effect of the battery during operation. In high-power application scenarios, the heat generated by the battery can be quickly dissipated through these channels, thereby reducing the battery temperature, extending the battery life, and improving the safety of the device.

[0049] In addition, the utility model uses the angle deformation between the metal spring 3 and the cover 4 to hold the battery, ensuring that the battery has a stable contact after installation. The 15-degree to 40-degree angle 6 between the conductive sheet 5 and the cover 4 makes the battery contact more firm and reliable, thereby improving the stability and performance of the electrical connection. In practical applications, even if the device is subjected to vibration and impact, the battery can still maintain a stable electrical connection without loosening or poor contact, thereby ensuring the normal operation of the device.

Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0051] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
