Description

Technical Field

[0001] This technical solution relates to the field of battery connection technology, specifically to a quick-release battery latch structure for power tools. It is suitable for battery components of different shapes, such as prisms and rings. It achieves a stable connection through the cooperation of the latch and the groove, and also features convenient disassembly and high safety. Background Technology

[0002] Existing power tool battery latch structures have the following problems:

[0003] Traditional clips are prone to loosening due to vibration or external force, posing a risk of battery detachment; some structures lack clear feedback after the battery is installed, which can easily lead to misoperation. Summary of the Invention

[0004] The purpose of this application is to provide a battery latch structure that can solve the problem of latches easily becoming loose due to vibration or external force.

[0005] This application provides a battery locking structure, characterized in that it includes: a tool body, on which a housing is provided; a battery assembly is inserted into the housing. The housing and the battery assembly are fixedly connected.

[0006] The battery assembly has a buckle and a protrusion; the housing has a first groove and a second groove. The first groove engages with the buckle on the battery assembly, and the second groove contains a locking element that engages with the protrusion on the battery assembly. The battery assembly has a prism structure, and the buckle and protrusion on the battery assembly are not on the same side.

[0007] The locking element can deform within the second groove. The locking element is a spring clip, and its material is spring steel.

[0008] Compared to conventional battery assembly and casing connections that rely solely on clips and a first groove, this technical solution incorporates a locking element within a second groove that connects to a protrusion, with the clip and protrusion positioned on opposite sides. This mitigates the risk of battery detachment caused by traditional clips loosening due to vibration or external force. Furthermore, the connection is more secure and reliable.

[0017] Example

[0018] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0019] The following description, in conjunction with the accompanying drawings, details a battery latch structure provided in this application through specific embodiments and application scenarios.

[0020] refer to Figure 1-6 This application provides a battery locking structure, characterized in that it includes: a tool body 100, which is a power tool such as an electric drill, electric hammer, electric saw, angle grinder, marble cutter, stone cutter, electric reciprocating saw, electric grinder, sander, polisher, angle grinder, electric polisher, electric wrench, electric screwdriver, concrete vibrator, electric pick, electric chainsaw, electric pruning shears, electric sprayer, etc., that requires the use of this battery locking structure; a housing 110 is provided on the tool body 100; the housing 110 is provided with soft rubber anti-slip, and the housing 110 is in the form of a left and right clasping shape, such as... Figure 3 As shown, Figure 3 Only half of the housing 110 is shown, which is composed of two nearly identical halves that embrace each other.

[0021] The housing 110 has a region for accommodating the battery assembly 200. Within this region, the battery assembly 200 is fixedly connected to the housing 110, such that the power output portion of the battery assembly 200 is in contact with the power input portion inside the tool body 100. The battery assembly 200 outputs power energy to the tool body 100. The tool body 100 contains a motor, a control circuit board, and a reducer. When the tool body 100 receives power energy, the motor inside the tool body 100 can be controlled to rotate by the switching element on the control circuit board. The reducer outputs the mechanical rotation, and the tool body 100 achieves its actual purpose, such as drilling, grinding, or cutting, through external actuators.

[0022] The battery assembly 200 is provided with a buckle 211 and a protrusion 201; the housing 110 is provided with a first groove 111 and a second groove 112, wherein the housing 110 should include at least one first groove 111 and one second groove 112. Preferably, an even number of symmetrical first grooves 111 and an even number of symmetrical second grooves 112 are provided on the housing 110; this will provide better circumferential fixation for the columnar battery assembly 200 and reduce the gap between the battery assembly 200 and the tool body 100 due to vibration. The first groove 111 engages with the buckle 211 on the battery assembly 200, and the second groove 112 is provided with a locking member 300, which engages with the protrusion 201 on the battery assembly 200.

[0023] like Figure 3-5 As shown, the battery assembly 200 has a prism structure, and the buckle 211 and the protrusion 201 on the battery assembly 200 have different surfaces. The different surfaces of the buckle 211 and the protrusion 201 can make the connection between the battery assembly 200 and the housing 110 uniformly stressed in the circumferential direction, and the connection is tight.

[0024] like Figure 6 As shown, the locking member 300 can deform within the second groove 112. The locking member 300 is preferably a spring sheet, and the material of the spring sheet is spring steel. Spring steel has good elasticity. When the battery assembly 200 is inserted into the housing 100, the protrusion 201 applies pressure to the locking member 300, causing the locking member 300 to deform. Then, after the locking member 300 springs back to its initial state, it locks the protrusion 201 within the housing 110.

[0025] The battery assembly 200 has a circular ring structure; if the battery assembly 200 has a cylindrical structure, then the side of the battery assembly 200 is an annular curved surface, and the buckle 211 and the protrusion 201 are located on this annular curved surface. The buckle 211 and the protrusion 201 should be evenly distributed on the annular surface of the battery assembly 200. This ensures that the connection between the battery assembly 200 and the housing 110 is evenly stressed circumferentially and securely connected.

[0026] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
