[0002] A high-pressure cleaner is a machine that uses a power device to make a high-pressure plunger pump generate high-pressure water to wash the surface of an object. It can remove and wash away dirt to achieve the purpose of cleaning the surface of an object. Currently, the lithium-ion cleaning machine in the industry basically uses a battery pack installed in the cleaning machine, and the battery pack supplies power to the power device.

[0003] At present, the China Patent Network discloses a power supply system and a cleaning machine for a cleaning machine [Authorization Announcement No.: CN216334044U], including a battery pack packaging box detachably mounted on a bracket, a spring and a terminal plug are installed at the bottom of the battery pack accommodating chamber, and the terminal plug supplies power to the device body through the battery pack assembly, and a battery pack limiting mechanism is provided on one side of the top of the battery pack accommodating chamber. The battery pack limiting mechanism is used to fix the battery pack. The battery pack limiting mechanism includes a mounting seat, a limiting member and a spring member. The mounting seat is mounted on one side of the top of the battery pack accommodating chamber. The limiting member is rotatably connected to the mounting seat through a rotating shaft. The spring member is sleeved on the rotating shaft and is located between the limiting member and the rotating shaft. The spring is used to provide pressure to the limiting member to form a limit between it and the battery pack to fix the battery pack. A terminal interface is provided at the bottom of the battery pack for connecting the terminal plug. When the battery pack is inserted into the battery pack accommodating cavity, the spring is compressed until the terminal plug is inserted into the terminal interface. The battery pack is fixedly installed under the cooperation of the battery pack limiting mechanism and the limiting structure. When the battery pack needs to be removed or replaced, the limiting part is pressed to disengage from the limiting structure, and the battery pack loses its limiting effect. Under the elastic force of the spring, the battery pack is ejected for easy removal or replacement.

[0004] The battery pack limiting mechanism in the above patent has the following defects: a battery pack limiting mechanism is separately arranged in each battery accommodating cavity, multiple battery pack limiting mechanisms occupy a large space, and each battery pack limiting mechanism must be installed separately, which makes the assembly more complicated and the manufacturing cost is high.

Similarly, the right clamping piece is clamped with the battery pack in the right battery compartment, so that the battery pack in the right battery compartment will not fall out of the right battery compartment. When the battery pack in the left battery compartment needs to be taken out, the trigger is swung to the left, and the trigger drives the left clamping piece to move to the right to overcome the force of the spring. At this time, the right clamping piece does not move, so that the left clamping piece and the battery pack are released from the clamping relationship, thereby facilitating the removal of the battery pack in the left battery compartment; when the battery pack in the right battery compartment needs to be taken out, the trigger is swung to the right, and the trigger drives the right clamping piece to move to the right to overcome the force of the spring. At this time, the left clamping piece does not move, so that the right clamping piece and the battery pack are released from the clamping relationship, thereby facilitating the removal of the battery pack in the right battery compartment. The battery pack clamping structure is arranged at a position between the two battery compartments, so that one battery pack clamping assembly can be clamped with the battery packs in the two battery compartments at the same time, and one trigger can respectively control the left clamping piece and the right clamping piece to release the clamping relationship with the battery pack. Compared with the prior art in which one battery compartment is equipped with one battery pack clamping assembly, the number of battery pack clamping assemblies is reduced, so that the space occupied by the battery pack clamping assembly is smaller, the machine volume is smaller, and it is convenient to transport, which improves the convenience of assembling the battery pack clamping assembly on the battery box and reduces the manufacturing cost.

Through the arrangement of this structure, the left clamping member and the right clamping member are respectively clamped with the battery pack in the corresponding battery compartment under the action of the spring, the left end of the sliding part 2 abuts against the right end of the guide groove 1, and the left end of the sliding part 2 abuts against the right end of the guide groove 1, so that when the trigger swings to the left to drive the left clamping member to move to the right, the right clamping member does not move, and when the trigger swings to the right to drive the right clamping member to move to the left, the left clamping member does not move.

[0010] In the above-mentioned battery pack clamping structure of a lithium battery cleaning machine, positioning holes are provided on one side surface of the left clamping piece and one side surface of the right clamping piece, and one end of the spring is located in the positioning hole of the left clamping piece and the other end is located in the positioning hole of the right clamping piece. Through the arrangement of this structure, the arrangement of the two positioning holes facilitates the installation and positioning of the two ends of the spring.

[0011] In the above-mentioned battery pack clamping structure of a lithium battery cleaning machine, the left clamping member and the right clamping member are arranged opposite to each other, and the springs are at least two, and all the springs are arranged at intervals along the length direction of the left clamping member. Through the arrangement of this structure, the left clamping member and the right clamping member are subjected to relatively uniform force at various positions, which facilitates the movement and reset of the left clamping member and the right clamping member.

[0012] In the above-mentioned battery pack clamping structure of a lithium battery cleaning machine, the upper surface of the left clamping member has a left limit plate, the upper surface of the right clamping member has a right limit plate, the lower end of the trigger has a left driving plate located on the left side of the left limit plate, and the lower end of the trigger has a right driving plate located on the right side of the right limit plate.

Through the arrangement of this structure, since the left end of the left clamping piece and the right end of the right clamping piece are both used for clamping with the battery pack, the arrangement of the reinforcing plate 1 and the reinforcing plate 2 improves the structural strength of the left end of the left clamping piece and the right end of the right clamping piece, making it difficult for the left end of the left clamping piece and the right end of the right clamping piece to break, thereby extending the service life of the left clamping piece and the right clamping piece.

[0015] Compared with the prior art, the battery pack clamping structure of the lithium battery cleaning machine of the utility model has the following advantages: the battery pack clamping structure is arranged at a position between the two battery compartments, so that one battery pack clamping assembly can be clamped with the battery packs in the two battery compartments at the same time, and one trigger can respectively control the left clamping member and the right clamping member to release the clamping relationship with the battery pack.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1 to Figure 7As shown, the battery pack locking structure of the lithium battery cleaning machine includes a battery box 1, the battery box 1 has a left battery compartment 2 and a right battery compartment 3, an isolation portion 4 is provided between the left battery compartment 2 and the right battery compartment 3, and a battery pack locking assembly 5 is arranged on the isolation portion 4, characterized in that the battery pack locking assembly 5 includes a left locking piece 6 arranged on the left battery compartment 2 side and a right locking piece arranged on the right battery compartment 3 side, a spring 9 is arranged between the left locking piece 6 and the right locking piece 7, the left locking piece 6 and the right locking piece 7 are both slidably arranged on the isolation portion 4, and the battery pack locking assembly 5 also includes a trigger 8 that can swing left and right, and the trigger 8 can drive the left locking piece 6 to move right relative to the right locking piece 7 or drive the right locking piece 7 to move left relative to the left locking piece 6. In this embodiment, the upper surface of the left clamping member 6 has a left limit plate 61, the upper surface of the right clamping member 7 has a right limit plate 71, the lower end of the trigger 8 has a left driving plate 80 located on the left side of the left limit plate 61, and the lower end of the trigger 8 has a right driving plate 81 located on the right side of the right limit plate 71. When a battery pack is installed in the battery compartment, the left clamping member 6 is clamped with the battery pack in the left battery compartment 2, so that the battery pack in the left battery compartment 2 will not fall out of the left battery compartment 2, and similarly, the right clamping member 7 is clamped with the battery pack in the right battery compartment 3, so that the battery pack in the right battery compartment 3 will not fall out of the right battery compartment 3. When the battery pack in the left battery compartment 2 needs to be taken out, the trigger 8 is swung to the left, and the trigger 8 drives the left locking member 6 to overcome the force of the spring 9 and move to the right. At this time, the right locking member 7 does not move, so that the left locking member 6 and the battery pack are released from the locking relationship, thereby facilitating the removal of the battery pack in the left battery compartment 2; when the battery pack in the right battery compartment 3 needs to be taken out, the trigger 8 is swung to the right, and the trigger 8 drives the right locking member 7 to overcome the force of the spring 9 and move to the right.

A pressing plate 11 is arranged in the mounting groove 42, and the lower end of the pressing plate 11 has a limiting surface 110 that is in contact with the left clamping member 6 and the right clamping member 7. The trigger 8 is arranged through the pressing plate 11, and a rotating shaft 12 is arranged in the pressing plate 11, and the middle part of the trigger 8 is sleeved on the rotating shaft 12. The setting of the pressing plate 11 limits the left clamping member 6 and the right clamping member 7 in the vertical direction to prevent the left clamping member 6 and the right clamping member 7 from falling out of the sliding groove 43; on the other hand, it provides an installation position for the trigger 8, so that the trigger 8 can swing left and right to drive the left clamping member 6 or the right clamping member 7.

[0028] like Figure 3 and Figure 4 As shown, a positioning hole 10 is provided on one side surface of the left clamping member 6 and one side surface of the right clamping member 7, one end of the spring 9 is located in the positioning hole 10 of the left clamping member 6, and the other end is located in the positioning hole 10 of the right clamping member 7. In this embodiment, the left clamping member 6 and the right clamping member 7 are arranged opposite to each other, there are at least two springs 9, and all the springs 9 are arranged at intervals along the length direction of the left clamping member 6.

[0029] like Figure 5 As shown, the upper surface of the left end of the left clamping member 6 and the upper surface of the right end of the right clamping member 7 both have a reinforcing plate 13, and a plurality of reinforcing plates 2 14 are arranged on the left and right sides of the reinforcing plate 1 13, and all reinforcing plates 2 14 on the left and right sides of the reinforcing plate 1 13 are arranged at intervals along the length direction of the left clamping member 6 or the right clamping member 7. Since the left end of the left clamping member 6 and the right end of the right clamping member 7 are both used for clamping with the battery pack, the arrangement of the reinforcing plate 1 13 and the reinforcing plate 2 14 improves the structural strength of the left end of the left clamping member 6 and the right end of the right clamping member 7, making it less likely for the left end of the left clamping member 6 and the right end of the right clamping member 7 to break, thereby extending the service life of the left clamping member 6 and the right clamping member 7.
