Description

Technical Field

[0001] The utility model relates to the field of electronic equipment, and more specifically, to an anti-detachment battery end cover. Background Art

[0002] The battery end cap is an important component of the battery, usually located at the end of the battery, used to close the battery and protect its internal structure from the influence of the external environment. It plays the role of sealing and protecting the internal materials of the battery and connecting the battery with the external circuit. In daily life, people will install two batteries into the battery compartment when installing the battery. Some battery compartments are arranged in a long strip shape, so people will contact the positive pole of one battery with the end cap on the negative pole of the other battery during installation. Since the end cap on the negative pole of the existing battery is often not set with a limit, when the battery compartment is hit, the contact position of the two batteries is easy to detach from the battery compartment, thereby causing the battery to fall.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a battery end cover that prevents separation.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-detachment battery end cover, including an end cover body, the end cover body is provided with a limit block for fixing to a spring in a battery compartment, the limit block is provided with a limit groove for accommodating the embedding of a positive electrode of the battery, the vertical cross-sections of the limit block and the limit groove are both semicircular and the center of the limit block and the limit groove is the same.

[0006] The utility model is further configured as follows: a plurality of thread grooves are provided on the inner wall of the limiting groove.

[0007] The utility model is further configured as follows: a positioning block is provided on the end cover body, and a space for accommodating the embedding of the positive electrode convex point of the battery is formed between the positioning block and the limiting block.

[0008] The utility model is further configured as follows: the horizontal cross section of the positioning block is configured in an inferior arc shape.

[0009] The utility model is further configured as follows: the outer diameter of the positioning block is smaller than the outer diameter of the limiting block, and the outer diameter of the limiting block is equal to the diameter of the end cover body.

[0010] The utility model is further configured as follows: the limit block and the limit groove are both provided with rounded corners.

[0011] The utility model is further configured as follows: the end cover body is made of metal zinc.

[0012] In summary, the utility model has the following beneficial effects: by setting a limit block and the limit block can be fixed with a spring, when people install the batteries, they can first contact the end cover body of one of the batteries with the spring, and then rotate the battery so that the limit block is located under the spring. At this time, the spring has a limiting effect on the limit block, and then people install another battery into the battery compartment, first contact the limit block with the convex point on the positive pole of the battery, and then press the battery into the battery compartment, and rotate the battery installed later so that the limit block on the later installed battery is located under the convex point of the positive pole of the first installed battery. When the battery compartment is collided, the battery close to the spring side is limited by the spring, and the battery away from the spring side is limited by the positive pole convex point of the other battery, so that the two batteries can be stably installed in the battery compartment, thereby preventing the connection between the two batteries from detaching from the battery compartment, thereby preventing the batteries from falling off.

[0016] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] Example:

[0018] An anti-detachment battery end cover, such as Figure 1 and Figure 2 As shown, it includes an end cover body 1. Specifically, the end cover body 1 is made of metal zinc. Metal zinc has good electrical conductivity, which ensures good contact between the end cover body 1 and the battery, reduces resistance and energy loss, and improves the working efficiency of the battery. At the same time, metal zinc has excellent corrosion resistance. This is because zinc will form a dense basic zinc carbonate oxide film in a humid environment. This oxide film can effectively prevent further oxidation of the internal zinc metal. This characteristic enables the battery end cover to maintain its stability and durability under various environmental conditions, thereby extending the service life of the battery.

[0019] like Figure 1 and Figure 2As shown, a limit block 2 for fixing with a spring in the battery compartment is provided on the end cover body 1, and a limit groove 3 for accommodating the positive electrode of the battery is provided on the limit block 2. The vertical cross-sections of the limit block 2 and the limit groove 3 are both semicircular and the center of the limit block 2 and the limit groove 3 is the same. Specifically, a plurality of thread grooves 4 are provided on the inner wall of the limit groove 3. The design of the thread groove 4 can increase the contact area between the limit groove 3 and the spring, thereby ensuring the stability and safety of the battery. By providing the limit block 2 and fixing the limit block 2 with the spring, when installing the battery, people can first contact the end cover body 1 of one of the batteries with the spring, and then rotate the battery so that The limit block 2 is located below the spring. At this time, the spring has a limiting effect on the limit block 2. Then people install another battery into the battery compartment, first make the limit block 2 contact with the convex point on the positive electrode of the battery, and then press the battery into the battery compartment, rotate the battery installed later, so that the limit block 2 on the later installed battery is located below the convex point of the positive electrode of the first installed battery. When the battery compartment is collided, the battery close to the spring side is limited by the spring, and the battery far from the spring side is limited by the convex point of the positive electrode of the other battery, so that the two batteries can be stably installed in the battery compartment, thereby preventing the connection between the two batteries from detaching from the battery compartment, thereby preventing the batteries from falling.

[0020] Further, such as Figure 1 and Figure 2 As shown, a positioning block 5 is provided on the end cover body 1 and the horizontal cross-section of the positioning block 5 is in an inferior arc shape. A space for accommodating the embedding of the positive protrusion of the battery is formed between the positioning block 5 and the limiting block 2. The inferior arc-shaped positioning block 5 can match the protrusion on the positive electrode of the battery to form a tight fit. When the battery is installed in the battery compartment, the positive protrusion will naturally embed into the space formed between the positioning block 5 and the limiting block 2, thereby realizing accurate positioning and fixation of the battery. This design can ensure that the battery will not shake or move after installation, improve the stability and reliability of the battery installation, and effectively prevent the battery from falling off from the battery compartment.

[0021] Specifically, Figure 1 and Figure 2As shown, the outer diameter of the positioning block 5 is smaller than the outer diameter of the limit block 2, and the outer diameter of the limit block 2 is equal to the diameter of the end cover body 1. Since the outer diameter of the positioning block 5 is smaller than the outer diameter of the limit block 2, this design allows the positioning block 5 to fit more compactly around the positive electrode protrusion of the battery, while ensuring that the limit block 2 has sufficient size to provide stable support and fixation, and the outer diameter of the limit block 2 is equal to the diameter of the end cover body 1, which means that the limit block 2 and the end cover body 1 form a whole, which enhances the strength and stability of the overall structure, so that the battery end cover can better withstand pressure when subjected to external force, reducing the risk of deformation or damage, and the limit block 2 and the limit groove 3 are both provided with rounded corners, and the rounded corner design plays a role in lubrication and guidance at the contact point between the limit block 2 and the limit groove 3, making the battery smoother during installation and removal, and reducing the possibility of jamming or scratching.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
