Description

Technical Field

[0001] This utility model belongs to the field of battery door technology, and in particular to a battery door telescopic rotating shaft structure. Background Technology

[0002] Existing lithium battery cleaning machines include a battery compartment and a lithium battery pack installed inside the battery compartment. The lithium battery cleaning machine has a battery door for sealing the entrance of the battery compartment. The battery door is rotatably connected to the housing of the lithium battery cleaning machine via a rotating shaft. A torsion spring is sleeved on the rotating shaft. Under the action of the torsion spring and when the battery door is not subjected to external force, the battery door is naturally pulled to a tightly closed state.

[0003] Currently, the China Patent Network discloses a battery door structure assembly [Authorization Announcement No.: CN203386826U]. The battery door is pivotally mounted to the body via a pivot mounting part of a rotating plate. The body also includes a pair of lugs corresponding to the pivot mounting part of the battery door as described above. The pair of lugs are provided with mounting holes so that the battery door can be pivotally mounted to the body by passing through the mounting holes and the pivot mounting part of the battery door.

[0004] The aforementioned battery door structure assembly has the following defects: After the rotating shaft is inserted from the outside into the mounting hole and the rotating shaft mounting part, if the rotating shaft is not positioned, after long-term use, the rotating shaft is prone to gradually protruding out of the mounting hole, which will affect the rotating connection structure between the battery door and the housing, making the stability of the rotating connection structure not high enough; when the battery door needs to be disassembled, the rotating shaft needs to be pulled out from the rotating shaft mounting part and the mounting hole, and the operation of pulling out the rotating shaft is also extremely inconvenient. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a battery door telescopic rotating shaft structure. The technical problem to be solved by this utility model is: how to solve the problems of insufficient stability and inconvenient disassembly of the existing battery door rotating shaft after installation.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A battery door telescopic rotating shaft structure includes a main housing, a battery door, and a rotating shaft. The battery door has rotating shaft mounting portions on both the left and right sides of its rear end. The rotating shaft mounting portion has blind holes along its axial direction on its outward-facing end face. Each blind hole contains a spring and a rotating shaft. One end of the rotating shaft abuts against the spring, and the other end extends out of the blind hole. The main housing has fixing seats on both the left and right sides of the rear end of the battery door. Each fixing seat has a shaft hole on its side facing the rotating shaft, with one end of the rotating shaft extending into the shaft hole. Each fixing seat also has a disassembly hole communicating with the shaft hole on its side away from the rotating shaft.

[0008] When assembling the battery door with the main unit housing, first move the rear end of the battery door to a position close to the two fixed seats. Then, use a tool to press against one end of the rotating shaft and squeeze the rotating shaft, causing it to move into the blind mounting hole against the force of the spring. Next, move the battery door further so that the rotating shaft mounting part gradually moves between the two fixed seats. Then, release the tool. Under the force of the spring, the rotating shaft tends to move outward. Initially, the end face of the rotating shaft rests against the side wall of the fixed seat. As the rotating shaft mounting part continues to move to the shaft hole position, one end of the rotating shaft extends into the shaft hole, completing the assembly of the battery door and the main unit housing. Under the force of the spring, the rotating shaft of this structure moves outward along the axial direction of the rotating shaft mounting part, so that one end of the rotating shaft extends into the shaft hole. Under the action of no external force, the rotating shaft will basically not disengage from the shaft hole, and the installation of the rotating shaft is relatively stable. This improves the stability of the installation of the battery door and the main body housing, and the assembly operation is also relatively simple. When disassembling the battery door, the tool is extended into the shaft hole through the disassembly hole and pressed against the end face of the rotating shaft. The tool presses the end face of the rotating shaft, causing the rotating shaft to overcome the force of the spring and move into the interior of the mounting blind hole until the rotating shaft disengages from the shaft hole. At this time, the battery door can be removed from the main body housing. The disassembly process of the battery door is also very convenient.

[0009] In the aforementioned battery door telescopic rotating shaft structure, the rotating shaft can be pressed and fully retracted into the mounting blind hole. This structure ensures that the battery door can be installed and removed smoothly.

[0010] In the aforementioned battery door telescopic rotating shaft structure, the axis of the disassembly hole is offset from the axis of the shaft hole. This structure ensures that the rotating shaft will not come out of the disassembly hole, while also allowing tools to easily extend through the disassembly hole into the shaft hole to move the rotating shaft.

[0011] In the aforementioned battery door telescopic rotating shaft structure, the fixing base and the main housing are integrally formed. The integral formation of the fixing base and the main housing provides high structural strength and makes it less prone to breakage.

[0012] In the aforementioned battery door telescopic rotating shaft structure, the side of the fixed base facing the rotating shaft has a guide ramp for guiding the rotating shaft into the shaft hole. The guide ramp design allows for easy movement of the rotating shaft into the mounting blind hole by gently pushing it, so that the end face of the rotating shaft rests against the guide ramp. Then, the battery door can be moved directly to move the rotating shaft along the guide ramp to the shaft hole position, further facilitating the assembly of the battery door and the main housing.

[0013] In the aforementioned battery door telescopic rotating shaft structure, the inward-facing end face of the rotating shaft mounting part has a protruding mounting post. A torsion spring is fitted onto the mounting post. The first torsion arm of the torsion spring abuts against the inner top surface of the battery door, and the second torsion arm of the torsion spring abuts against the outer surface of the main housing. The mounting post facilitates the assembly of the torsion spring, and the torsion spring allows the battery door to automatically reset and close after being opened.

[0014] Compared with the prior art, the battery door telescopic rotating shaft structure of this utility model has the following advantages: Under the action of the spring, the rotating shaft moves outward along the axial direction of the rotating shaft mounting part, so that one end of the rotating shaft extends into the shaft hole. Under the action of no external force, the rotating shaft will basically not disengage from the shaft hole, and the installation of the rotating shaft is relatively stable; it improves the stability of the installation of the battery door and the main body housing, and the assembly operation is also relatively simple; when disassembling the battery door, the tool extends into the shaft hole through the disassembly hole and presses against the end face of the rotating shaft. The tool squeezes the end face of the rotating shaft, causing the rotating shaft to overcome the action of the spring and move into the interior of the mounting blind hole until the rotating shaft disengages from the shaft hole. At this time, the battery door can be removed from the main body housing, and the disassembly process of the battery door is also very convenient. Attached Figure Description

Detailed Implementation

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figures 1 to 7 As shown, the battery door telescopic rotating shaft structure includes a main housing 1, a battery door 2, and a rotating shaft 3. The left and right sides of the rear end of the battery door 2 each have a rotating shaft mounting portion 20. A blind mounting hole 21 is formed along the axial direction on the outward-facing end face of the rotating shaft mounting portion 20. A spring 4 and a rotating shaft 3 are installed in each blind mounting hole 21. One end of the rotating shaft 3 abuts against the spring 4, and the other end extends out of the blind mounting hole 21. The rotating shaft 3 can be pressed and fully retracted into the blind mounting hole 21. The left and right sides of the main housing 1 at the rear end of the battery door 2 each have a fixing seat 5, which is integrally formed with the main housing 1. Each fixing seat 5 has a shaft hole 6 on the side facing the rotating shaft 3, with one end of the rotating shaft 3 extending into the shaft hole 6. Each fixing seat 5 has a disassembly hole 7 on the side away from the rotating shaft 3, communicating with the shaft hole 6. The axis of the disassembly hole 7 is offset from the axis of the shaft hole 6. The side of the fixing seat 5 facing the rotating shaft 3 has a guide slope 9 for guiding the rotating shaft 3 into the shaft hole 6. When assembling the battery door 2 with the main housing 1, first move the rear end of the battery door 2 to a position close to the two fixed seats 5. Then, use a tool to press against one end of the rotating shaft 3 and squeeze the rotating shaft 3, so that the rotating shaft 3 overcomes the force of the spring 4 and moves into the mounting blind hole 21. Then move the battery door 2 again so that the rotating shaft mounting part 20 gradually moves between the two fixed seats 5. Then release the tool. Under the force of the spring 4, the rotating shaft 3 has a tendency to move outward. At first, the end face of the rotating shaft 3 abuts against the guide slope 9. The rotating shaft 3 moves along the guide slope 9 until the rotating shaft 3 is inserted into the shaft hole 6, thus completing the assembly of the battery door 2 and the main housing 1. Under the force of the spring 4, the rotating shaft 3 of this structure moves outward along the axial direction of the rotating shaft mounting part 20, so that one end of the rotating shaft 3 extends into the shaft hole 6. Under the action of no external force, the rotating shaft 3 will basically not disengage from the shaft hole 6, and the installation of the rotating shaft 3 is relatively stable. This improves the stability of the installation of the battery door 2 and the main body housing 1, and the assembly operation is also relatively simple. When disassembling the battery door 2, the tool extends into the shaft hole 6 through the disassembly hole 7 and presses against the end face of the rotating shaft 3. The tool squeezes the end face of the rotating shaft 3, causing the rotating shaft 3 to overcome the force of the spring 4 and move into the interior of the mounting blind hole 21 until the rotating shaft 3 disengages from the shaft hole 6. At this time, the battery door 2 can be removed from the main body housing 1. The disassembly process of the battery door 2 is also very convenient.

[0025] like Figure 4As shown, the inward-facing end face of the rotating shaft mounting part 20 has a protruding mounting post 22. A torsion spring 8 is fitted onto the mounting post 22. The first torsion arm 80 of the torsion spring 8 abuts against the inner top surface of the battery door 2, and the second torsion arm 81 of the torsion spring 8 abuts against the outer surface of the main housing 1. The mounting post 22 facilitates the assembly of the torsion spring 8, and the torsion spring 8 enables the battery door 2 to automatically reset and close after being opened.

[0026] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
