Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and more particularly to a lithium battery device for a sweeper with a protection function. Background Art

[0002] The sweeper uses the movement of the gear to drive the garbage to complete the cleaning work. Pure suction sweepers generally require a lot of power. At present, they basically use electric motors to complete the power supply. Pure suction sweepers have a simple structure but are large in size, suitable for cleaning large areas.

[0003] However, in the existing technology, lithium batteries used in sweepers are often equipped with a quick-release structure to facilitate maintenance and battery replacement during daily use to ensure the working time of the sweeper. However, after the traditional quick-release structure is fastened, both removal and insertion require the handle to be released and manually unlocked and locked step by step. Unlocking and locking cannot be performed simultaneously, resulting in inconvenient operation of the quick-release structure. In view of this, we propose a lithium battery device for sweepers with a protective function. Utility Model Content

[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a lithium battery device for sweeping vehicles with a protective function, so as to solve the technical problem that the lithium batteries currently used in sweeping vehicles are often provided with a quick-release structure on the lithium battery device when in use. However, after the traditional quick-release structure is fastened, it is necessary to leave the handle and manually unlock and lock it step by step to take it out and put it in, and it is impossible to unlock and lock it synchronously, which leads to the inconvenience of operating the quick-release structure.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a lithium battery device for a sweeping vehicle with a protective function, comprising a housing provided in a battery compartment on a main body of the sweeping vehicle;

[0006] A groove is provided at the center of one end of the shell, and a guide groove connected to the groove is provided in the center of one end of each side of the sweeper body, a locking assembly is provided in the groove and the two guide grooves, and locking grooves for inserting the locking assembly are provided on both sides of the battery compartment;

[0007] The locking assembly includes a rotating seat rotatably arranged in the groove, a handle groove is provided on the side of the rotating seat away from the shell, a shaft is fixedly installed at the center of one side of the rotating seat, and the shaft is rotatably arranged in the groove, and the rotating seat is provided with two arc-shaped pushing grooves in a circular array on the side facing the sweeper body, and the two arc-shaped pushing grooves are movably provided with locking plates slidably arranged in the corresponding guide grooves;

[0008] A pushing arc surface is provided on one side of the arc-shaped pushing groove, and a squeezed arc surface is provided on one end of the locking plate facing the shaft and fitting the pushing arc surface. One end of the locking plate passes through the guide groove and is inserted into the locking groove.

[0009] The utility model provides a locking assembly on the shell. When maintenance and battery replacement are required, the shell is lifted by gripping the handle groove, thereby placing the lithium battery device in the battery compartment. The handle groove is then gripped and rotated to rotate the rotating seat. The two locking plates are pushed out of the two guide grooves respectively through the two arc-shaped pushing grooves, so that the locking plates slide out of the guide grooves and insert into the locking grooves in the battery compartment, completing the locking of the lithium battery device. Locking and unlocking can be achieved by twisting the rotating seat provided with the handle groove. Unlocking and locking can be performed simultaneously, effectively solving the problem of inconvenient operation of the quick-release structure.

[0010] Preferably, an arc-shaped guide groove is provided on one side of the arc-shaped pushing groove, and a guide column is constructed at one end of the locking plate and is slidably arranged in the arc-shaped guide groove.

[0011] Preferably, a plurality of battery packs are equidistantly arranged in the shell, and an end cover is detachably mounted on one end of the shell away from the locking assembly.

[0012] Preferably, two fixing ears A are symmetrically configured on both sides of the shell, and a fixing ear B is centrally configured on both sides of the shell.

[0013] Preferably, two mounting slots A for the corresponding fixing ears A to be inserted are symmetrically provided on both sides of the end cover, and the fixing ears A are provided with fixing bolts A fixed in the end cover.

[0014] Preferably, mounting grooves B for the corresponding fixing ears B to be inserted into are centrally provided on both sides of the end cover, and fixing bolts B fixed in the end cover are provided in the fixing ears B.

[0015] Preferably, two guide grooves A are symmetrically provided on both sides of the shell, and two guide grooves B are symmetrically provided on both sides of the end cover, the guide grooves B are connected to the guide grooves A, and two guide keys are symmetrically constructed on both sides of the battery compartment, and the guide keys are slidably arranged in the corresponding guide grooves A and guide grooves B.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The utility model provides a locking assembly on the shell. When maintenance and battery replacement are required, the shell is lifted by gripping the handle groove to place the lithium battery device in the battery compartment. The handle groove is then gripped and rotated to rotate the rotating seat. The two locking plates are pushed out of the two guide grooves respectively through the two arc-shaped pushing grooves, so that the locking plates slide out of the guide grooves and insert into the locking grooves in the battery compartment, completing the locking of the lithium battery device. Locking and unlocking can be achieved by twisting the rotating seat with the handle groove. Unlocking and locking can be performed simultaneously, effectively solving the problem of inconvenient operation of the quick-release structure.

[0018] 2. The present invention also has several guide grooves A and guide grooves B opened on the shell and the end cover. After the lithium battery device is inserted into the battery compartment, the four guide keys on both sides slide in the corresponding guide grooves A and guide grooves B respectively, thereby ensuring the stability of the lithium battery after it is inserted and further improving the stability of the lithium battery layout.

The cam 302 is fixedly mounted on the side of the cam 301 and the cam 302 is rotatably mounted on the side of the cam 301. The cam 302 is fixedly mounted on the side of the cam 301 and the cam 302 is rotatably mounted on the side of the cam 301. The cam 302 is fixedly mounted on the side of the cam 301 and the cam 302 is rotatably mounted on the side of the cam 301. The cam 302 is fixedly mounted on the side of the cam 301 and the cam 302 is rotatably mounted on the side of the cam 301. Two arc-shaped pushing grooves 303 are formed in a circular array on the side of the cam 301 facing the cam 301. The two arc-shaped pushing grooves 303 are movably provided with locking plates 304 slidingly arranged in the corresponding guide grooves 7.
