Description

Technical Field

[0001] This utility model relates to a fast charging interface structure for lithium batteries, belonging to the field of lithium battery technology. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. A lithium battery fast charging interface is an access port for charging electric vehicles or batteries, used to transmit power to the lithium battery via wires.

[0003] Chinese Patent Publication No. (CN 213071484 U) discloses a fast charging interface for lithium batteries, including a main body and a guide rail. The main body has a sliding groove on its outer side, and an outer cover is installed on the outer side of the sliding groove. The outer cover and the sliding groove are movably connected. The guide rail is located at the front end of the main body, and a baffle is installed on the inner side of the guide rail. The baffle is movably connected to the guide rail. A hinge is installed below the main body, and a support plate is connected to the outer side of the hinge. The main body and the hinge are connected by screws, and the hinge and the support plate are also connected by screws. A spring is fixed inside the main body, and a top rod is connected to the top of the spring. The main body and the spring are fixedly connected, while the spring and the top rod are movably connected. This invention has a simple structure and is easy to use. It effectively solves the problem that without a protective structure to support the connection, the interface is prone to excessive wear after prolonged use. It also facilitates operation by workers. Existing charging devices are typically plugged directly into the charging slot for charging. However, prolonged plugging and unplugging can cause the connection to loosen, resulting in charging failure and affecting normal use.

[0004] To address this, a fast charging interface structure for lithium batteries is proposed. Utility Model Content

[0005] In view of this, the present invention provides a fast charging interface structure for lithium batteries to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model is implemented as follows: a lithium battery fast charging interface structure, comprising: A connecting assembly includes a protective shell, a charging slot, a fixing block, a moving rod, and a connecting rod. The rear side of the charging slot is fixedly connected to the front side of the protective shell. The inner side of the fixing block is fixedly connected to the outer side of the charging slot.

Detailed Implementation

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] Example 1 like Figure 1-3As shown, this utility model embodiment provides a lithium battery fast charging interface structure, including: a connecting assembly, which includes a protective shell 101, a charging slot 102, a fixing block 103, a moving rod 104, and a connecting rod 105. The rear side of the charging slot 102 is fixedly connected to the front side of the protective shell 101, the inner side of the fixing block 103 is fixedly connected to the outer side of the charging slot 102, the inner side of the moving rod 104 extends into the interior of the fixing block 103, the outer side of the moving rod 104 extends into the outer side of the fixing block 103, and the outer side of the connecting rod 105 extends into the interior of the fixing block 103. The inner side of the connecting rod 105 is fixedly connected to the inner side of the moving rod 104 and extends through the interior of the fixing block 103. Two protective shells 101 are provided, and the two protective shells 101 are fixedly connected to the left and right sides of the charging slot 102 respectively. The inner side of the connecting rod 105 is curved and is movably connected to the interior of the connecting block 202. A tension spring 106 is sleeved on the surface of the connecting rod 105. The inner side of the tension spring 106 is fixedly connected to the outer side of the charging slot 102, and the outer side of the tension spring 106 is fixedly connected to the inner side of the connecting rod 105.

[0022] During charging connection, the pull force of the tension spring 106 causes the moving rod 104 to move the connecting rod 105 inward simultaneously, thus fixing the connection. Since the inner side of the connecting rod 105 is curved, the inner side of the connecting rod 105 is squeezed during plug-in installation, making it easier for workers to fix it and improving the stability of the connection during charging connection.

[0023] Example 2 like Figure 4-6 As shown, in one embodiment, the fixing assembly includes a movable door 201, a connecting block 202, a mating block 203, a fixing rod 204, and a compression spring 205. The front side of the movable door 201 is movably connected to the rear side of the protective shell 101 via a pivot. The left side of the connecting block 202 is fixedly connected to the right side of the movable door 201. The left side of the mating block 203 is fixedly connected to the left side of the protective shell 101. A cavity 208 is formed inside the mating block 203. The front side of the fixing rod 204 extends through the cavity 208 to the front side of the mating block 203. The rear side of the fixing rod 204 is movably connected to the front side of the mating block 203. The bottom of the compression spring 205 is fixedly connected to the top of the fixing rod 204, and the top of the compression spring 205 is fixedly connected to the inside of the cavity 208. The inside of the fixing block 103 is fixedly connected to the sliding rod 107. The connecting rod 105 is sleeved on the surface of the sliding rod 107. The surface of the connecting block 202 is provided with an insertion groove 206. The rear side of the fixing rod 204 is movably connected to the inside of the insertion groove 206. The inside of the mating block 203 is provided with a limiting groove 207. The left side of the fixing rod 204 is movably connected to the inside of the limiting groove 207.

[0024] When installing the battery, the fixed rod 204 is pulled to open the movable door 201. After assembly, the spring force of the compression spring 205 pushes the fixed rod 204 into the interior of the connecting block 202 to fix the movable door 201. By setting the limiting groove 207, the fixed rod 204 moves according to the movement trajectory provided by the limiting groove 207 when it moves.

[0025] When this utility model is in operation: pulling the fixing rod 204 upward causes the fixing rod 204 to move upward along the movement trajectory provided by the limiting groove 207. While the fixing rod 204 moves upward, it compresses the compression spring 205. At this time, the battery can be installed. When docking for charging, it can be directly plugged in. During the insertion process, the connecting rod 105 is squeezed, and the tension spring 106 is stretched. The return force of the tension spring 106 ensures a good fixing effect and prevents the connection from becoming loose during charging.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
