Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to a lead-acid battery cover and handle, which is used in lead-acid batteries. Background Technology

[0002] The diversification of vehicle models in the domestic market, along with the upgrades in the configurations of new energy vehicles and traditional fuel vehicles, has led to more refined requirements for the functions of automotive components. Previously, the primary function of lead-acid batteries in automobiles was to provide electrical energy. However, with the booming development of the automotive industry, automakers have placed more demands on the 12V low-voltage power supplies used in automobiles. For example: 1. In the fully automated assembly workshops of automakers, the components must be level during the process of robotic arms handling battery parts to prevent damage during placement. 2. During assembly into the vehicle, the components must fit tightly to prevent noise from the parts during vehicle operation, which could affect the customer's driving experience.

[0003] Based on this need, this utility model designs a new type of lead-acid battery cover and handle. The design of the cover and handle can solve the problem of the battery not swaying horizontally when lifted with a single handle. In addition, the battery cover and handle adopt a tight fit structure, which can be suspended in any direction. The tight fit prevents swaying and solves the problem of loose parts making noise. Utility Model Content

[0004] This utility model provides a large cover and handle for a lead-acid battery. The design of the cover and handle can solve the problem of the battery not swaying horizontally when lifted with a single handle. In addition, the battery cover and handle adopt a tight fit structure, which can be suspended in any direction. The tight fit prevents swaying and solves the problem of loose parts making noise.

[0005] The technical solution of this utility model is: a lead-acid battery cover and handle, comprising a cover and a handle, characterized in that: cylindrical mating posts and handle limiting steps are symmetrically provided on one side of the upper center of the two long sides of the cover; cylindrical mating holes that mate with the two cylindrical mating posts and handle positioning slopes that mate with the handle limiting steps are provided on both sides of the handle; the cylindrical mating posts and cylindrical mating holes are fitted with an interference fit; the handle positioning slope is at the maximum opening angle of the handle when it contacts and is positioned with the handle limiting steps.

[0006] In the technical solution of this utility model, when the handle positioning slope and the handle limiting step are in contact and positioned, the top of the handle is located in the direction of the vertical center line of the two long sides of the cover.

[0007] In the technical solution of this utility model, the maximum opening angle of the handle is less than 90°.

[0008] The maximum opening angle of the handle in the technical solution of this utility model is 50°.

[0009] In the technical solution of this utility model, the two long sides of the cover are provided with side grooves that cooperate with the side of the handle; the top of the two long sides of the cover is provided with a crossbar groove that cooperates with the top crossbar of the handle.

[0010] In the technical solution of this utility model, the handle limiting step is located at the bottom corner of the side groove, which is close to the cylindrical mating column.

[0011] In the technical solution of this utility model, the handle positioning slope is located on the upper part of the handle side opposite to the handle top rod; the lower part of the handle side opposite to the handle top rod is arc-shaped.

[0012] The technical solution of this utility model describes that the lower part of the handle side, which is close to the handle top rod, is provided with a weight-reducing groove.

[0013] The advantages of this utility model are: 1. The angle of the handle and the step in the battery cover is increased from 30° to 50°, thus ensuring that the handle can only rotate to the center of the battery, which can ensure that the battery is level and does not wobble; 2. The cylindrical fitting hole in the battery handle and the positioning slope of the cover are fitted together, and the interference fit during rotation can ensure that the handle can be suspended in any direction.

[0014] This utility model is mainly used in the cover of lead-acid batteries. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3 As shown, one embodiment of the lead-acid battery cover and handle of this utility model consists of a cover and a handle.

[0021] The cover is the same as that of an existing lead-acid battery. The difference is that the upper center of each of the two long sides of the cover has symmetrical cylindrical mating posts 1-1 and handle limiting steps 1-2. The two long sides of the cover have side grooves that mate with the sides of the handle, and the top of each long side of the cover has a horizontal bar groove that mates with the top crossbar of the handle. The handle limiting step 1-2 is located at the bottom corner of the side groove, close to the cylindrical mating post 1-1.

[0022] The handle is a standard lead-acid battery handle, with cylindrical mating holes 2-1 on both sides that mate with the two cylindrical mating posts 1-1. The difference lies in the handle positioning slopes 2-2 on both sides, which mate with the handle limiting steps 1-2. These positioning slopes 2-2 are located on the upper part of the handle side opposite to the handle top rod, while the lower part of the handle side opposite to the handle top rod is arc-shaped. A weight-reducing groove is provided on the lower part of the handle side near the handle top rod. The handle positioning slopes 2-2 and the handle limiting steps 1-2 are in contact at the maximum opening angle of the handle. When the handle positioning slopes 2-2 and the handle limiting steps 1-2 are in contact, the top of the handle is located along the vertical center line of the two long sides of the battery cover. The maximum opening angle of the handle is 50°. Points 3 and 4 represent the cylindrical mating holes of the battery handle and the positioning slopes of the battery cover when the handle is rotated to its maximum position with the battery at the center, horizontal and stable.

[0023] The cylindrical mating post 1-1 and the cylindrical mating hole 2-1 are fitted with an interference fit, ensuring that the handle can only rotate to the maximum center of the battery, thus ensuring that the battery remains level and does not wobble. The handle positioning ramp 2-2 and the handle limiting step 1-2 are fitted with an interference fit during rotation, ensuring that the handle can be suspended in any direction.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
