Description

Technical Field

[0001] The utility model relates to the technical field of direct current motors, in particular to a direct current motor substrate with a packaging structure. Background Art

[0002] A DC motor is a rotating motor that can convert DC electrical energy into mechanical energy (DC motor) or mechanical energy into DC electrical energy (DC generator). It is a motor that can realize the mutual conversion of DC electrical energy and mechanical energy. When it operates as a motor, it is a DC motor that converts electrical energy into mechanical energy; when it operates as a generator, it is a DC generator that converts mechanical energy into electricity.

[0003] The base plate is arranged in the tail cover at the rear of the motor. In the existing base plates, most of the base plates are directly bolted inside the tail cover or are directly integrally formed with the motor housing. Among the two, the bolt fixing often lacks a sealing structure and is not very convenient for disassembly and assembly. Although the integral molding solves the sealing problem, it cannot be disassembled. Therefore, after the motor is damaged, the outer shell needs to be cut open for recycling, which reduces its secondary utilization value. Utility Model Content

[0004] The purpose of the utility model is to overcome the defect that in the prior art, most of the substrates are directly bolted to the inside of the tail cover or are directly integrally formed with the shell of the motor. Among the two, the bolted fixing often lacks a sealing structure and is not very convenient to disassemble and assemble. Although the integral forming solves the sealing problem, it cannot be disassembled. Therefore, after the motor is damaged, the shell needs to be cut open for recycling, which reduces the value of its secondary utilization. A DC motor substrate with a packaging structure is provided. The substrate body adopts a detachable installation structure, that is, it is clamped in the tail cover through a locking mechanism and a step mouth. When damage occurs inside the motor, it can be directly disassembled and the internal structure can be replaced and repaired. Therefore, the motor maintenance cost using the substrate body is low, and when installing the substrate body, it only needs to press the control to press the spring pin to make it snap into the pin hole reserved on the inner wall of the motor tail cover, and the operation is convenient and quick.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0019] The following is combined with Figure 1 -Attached Figure 2 , further illustrating the specific implementation of the utility model of a DC motor substrate with a packaging structure, overcomes the existing technology that most substrates are directly bolted to the inside of the tail cover or directly integrated with the motor housing. The bolt fixation often lacks a sealing structure and is not very convenient to disassemble and assemble. Although the integrated molding solves the sealing problem, it cannot be disassembled. Therefore, after the motor is damaged, the outer shell needs to be cut open for recycling, which reduces the value of its secondary use. The substrate body adopts a detachable installation structure, that is, it is clamped in the tail cover through a locking mechanism and a step mouth. When damage occurs inside the motor, it can be directly disassembled and the internal structure can be replaced and repaired. Therefore, the motor maintenance cost using the substrate body is low, and when installing the substrate body, it only needs to press the control to press the elastic pin to make it snap into the pin hole reserved on the inner wall of the motor tail cover, which is convenient and quick to operate. The utility model of a DC motor substrate with a packaging structure is not limited to the description of the following embodiments.

[0020] Embodiment 1:

[0021] This embodiment provides a DC motor substrate with a packaging structure, such as Figure 1-2 As shown, it includes a substrate body 1, which is installed in the tail cover of the DC motor. A step opening 8 is opened at the edge of the substrate body 1, and a sealing ring 7 is embedded and installed in the step opening 8. The sealing ring 7 surrounds the substrate body 1 along the circumference of the step opening 8. Such a structural arrangement can ensure the sealing of the substrate body 1 after installation. A locking mechanism is also provided at the edge of the substrate body 1. The locking mechanism includes a spring pin 5 and an elastic component. The elastic component is installed at one end of the spring pin 5, so that the spring pin 5 can pop out of the edge of the substrate body 1 or shrink to the inside of the substrate body 1.

[0022] By adopting the above technical solution:

[0023] The device is installed in the tail cover of the DC motor when in use. The substrate body 1 adopts a detachable installation structure, that is, it is clamped in the tail cover through a locking mechanism and a step opening 8. When damage occurs inside the motor, it can be directly disassembled and the internal structure can be replaced and repaired. Therefore, the maintenance cost of the motor using the substrate body 1 is low. When installing the substrate body 1, it only needs to press and control the spring pin 5 to make it snap into the pin hole reserved on the inner wall of the motor tail cover. The operation is convenient and quick.

[0024] Example 2

[0025] On the basis of Example 1, in this embodiment, the sealing ring 7 is elastic, and the cross section of the sealing ring 7 is a semicircular structure. Such a structural setting can facilitate the installation of the substrate body 1, and the substrate body 1 can be directly pressed to snap into the corresponding position.

[0026] There are two sets of locking mechanisms, which are symmetrically arranged on the two side edges of the substrate body 1 , so that the locking effect of the substrate body 1 can be ensured.

[0027] A cavity 4 is provided at the edge of the substrate body 1, one end of the spring pin 5 is inserted into the cavity 4, and the elastic component is located between one end of the spring pin 5 and the inner wall of the cavity 4. Such a structural arrangement enables the spring pin 5 to be retracted into the cavity 5 when pressed, and the substrate body 1 can be disassembled at this time. Conversely, when the spring pin 5 pops out and is inserted into the pin hole reserved on the inner wall of the motor tail cover, the substrate body 1 is assembled and fixed, and the operation is convenient and quick.

[0028] The elastic member is a spring.

[0029] An inserting hole 3 is provided on the outer surface of the substrate body 1, and a pressing groove is provided on the elastic pin 5 along the vertical direction, and the upper opening of the pressing groove adopts a wedge-shaped structure.

[0030] A plurality of metal guide plates 6 are embedded on the surface of the substrate body 1 , and a post installation hole 9 is provided on each of the plurality of metal guide plates 6 for installing a terminal post.

[0031] By adopting the above technical solution:

[0032] When it is necessary to control the retraction of the spring pin 5, it is only necessary to insert an appropriate wedge-shaped head tool into the socket 3. When the tool is inserted into the pressing groove, the spring pin 5 can be compressed and contracted, thereby realizing the disassembly of the substrate body 1. The operation is convenient and quick. The outer end of the spring pin 5 is wedge-shaped, so when installing, it is only necessary to press the substrate body 1.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
