Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a disassembly and assembly tool for a range extender. Background Art

[0002] With the development of science and technology, many high-tech products such as electric cars and electric drones that use battery life have emerged. However, due to the capacity limitations of existing power batteries and short battery life, the driving range of products such as drones is short and can only be used within the range allowed by the battery. In this regard, the range extender uses the original mature engine technology to compensate for the above shortcomings. The range extender is an additional energy storage component installed to increase the battery life. When the battery power is low, the range extender will automatically turn on and provide power to the battery. The range extender currently on the market is composed of an engine and a motor, and the output shaft of the engine and the motor shaft are connected by a tapered hole and a tapered shaft. Although it can transmit torque and axial force well, it takes a lot of force in the later disassembly and maintenance process, and it is difficult to disassemble.

[0003] Prior art, patent number (CN202022480115.9) mentions a disassembly and assembly tool for a range extender, which solves the problem of inconvenient use of existing disassembly and assembly tools, including a rod shaft fixed on the engine output shaft, a driving member screwed on the rod shaft, and a fixing member for fixing the rear end cover of the motor. The fixing member is sleeved on the driving member, and when the driving member moves axially upward on the rod shaft, it can drive the fixing member to move axially upward. The rod shaft forms a support point on the engine output shaft. Through the cooperation between the driving member and the fixing member, the driving member lifts the fixing member upward by rotation to achieve disassembly. This disassembly and assembly tool has a simple structure and is very easy to operate.

[0004] In the prior art, the traditional tapered hole structure is replaced with a threaded connection, and fixing parts and driving parts are added, which effectively solves the problem that it takes a lot of force and is difficult to disassemble during the later disassembly and maintenance process. However, since the main force of the fixed limiting driving part is to generate a lifting force by rotating the rod shaft, the connection stability between the driving part and the rod shaft cannot be effectively guaranteed when the rotation force is insufficient or too slow, thereby posing a major safety hazard.

[0007] Among them, the disassembly and assembly limiting assembly also includes a mounting groove and a limiting plate, the mounting groove is detachably connected to the rotating shaft and is located on the lower outer surface of the rotating shaft, and the limiting plate is detachably connected to the driving block and is located above the driving block.

[0008] Among them, the disassembly and assembly limit assembly also includes a limit groove and a fixing ring, the limit groove is fixedly connected to the rotating shaft and is located on the upper outer surface of the rotating shaft, and the fixing ring is detachably connected to the driving block and is located on the outer surface of the driving block.

The above-mentioned solution solves the problem that the main force of the fixed limiting driving member is to generate a lifting force by rotating the rod shaft, thereby failing to effectively ensure the connection stability between the driving member and the rod shaft when the rotation force is insufficient or too slow, thereby posing a greater safety hazard. It can be understood that the above-mentioned solution can be used in the When the rotating shaft 101 does not rotate or cannot drive the lifting block to provide lifting force for the driving block 106, the fixing block 105 will fix the driving block 106 inside the lifting ring 103, and at the same time, the limiting plate 107 will cooperate with the limiting groove 108 to effectively prevent the driving block 106 from detaching from the rotating shaft 101, thereby retaining the original beneficial effects while actively and effectively solving the problem that the main force of the fixed limiting driving member is to generate lifting force by rotating the rod shaft, and therefore when the rotation force is insufficient or the rotation force is too slow, the connection stability between the driving member and the rod shaft cannot be effectively guaranteed, thereby posing a greater safety hazard.

[0022] According to the present specific embodiment, the lifting ring 103 is fixedly connected to the rotating shaft 101 and is located at the center of the outer surface of the rotating shaft 101.

[0024] Secondly, the limiting groove 108 is fixedly connected to the rotating shaft 101 and is located on the outer surface of the upper end of the rotating shaft 101. The fixing ring 109 is detachably connected to the driving block 106 and is located on the outer surface of the driving block 106.

The fixing groove 111 is a functional conceptual component that cooperates with bolts in daily life to install the fixing ring 109 on the motor rotor housing, thereby limiting the position of the rotating shaft 101.

[0026] When the utility model is used and the shaft 101 does not rotate or cannot drive the lifting block to provide lifting force for the driving block 106, the fixing block 105 will fix the driving block 106 inside the lifting ring 103, and the limiting plate 107 will cooperate with the limiting groove 108 to effectively prevent the driving block 106 from detaching from the shaft 101, thereby retaining the original beneficial effects while actively and effectively solving the problem that the main force of the fixed limiting driving member is to generate lifting force by rotating the rod shaft, and therefore the connection stability between the driving member and the rod shaft cannot be effectively guaranteed when the rotation force is insufficient or the rotation force is too slow, thereby posing a greater safety hazard.
