Description

Technical Field

[0001] The utility model relates to the field of motors, in particular to a motor casing which saves installation space. Background Art

[0002] As we all know, the motor housing is the outer shell of the motor, which is usually used to accommodate the internal components of the motor and also plays a role of protection and support. It is usually made of metal materials, such as cast iron, aluminum alloy or steel.

[0003] Most existing speed sensors are installed on the rear cover of the casing, perpendicular to the motor axis, which wastes space on the rear cover of the casing. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies of the prior art, the utility model provides a motor housing which saves installation space.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a motor housing that saves installation space, including a housing body and a speed sensor, wherein the speed sensor is installed outside the housing body, and the speed sensor is installed parallel to the motor shaft.

[0008] Furthermore, the utility model has the following improvements: two clamping plates are symmetrically arranged on the outer wall of the casing body, a base is arranged between the two clamping plates, the speed sensor is located above the base, a bottom block is fixedly arranged at one end of the base, a screw is rotatably arranged on the outer wall of the casing body, the screw passes through the bottom block, and the screw is threadedly connected to the bottom block, a cavity is arranged on the top of the clamping plate, a spring is arranged inside the cavity, and a limit block for limiting the speed sensor is arranged at one end of the spring.

[0009] In order to facilitate the assembly of the speed sensor, the improvement of the utility model is that the limit block is a trapezoidal structure.

[0010] In order to facilitate the operation of the screw rod, the utility model has the following improvements: a toggle block is provided at the top end of the screw rod.

[0011] Furthermore, the present invention is improved in that the clamping plate, the limiting block, the base and the screw are all made of metal.

[0012] In order to make the speed sensor more firmly installed, the utility model has the following improvements: an anti-skid pad is provided at the upper end of the base.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a motor housing that saves installation space and has the following beneficial effects:

[0015] The motor housing saves installation space, the speed sensor is fixed on the outer wall of the housing body, the speed sensor can be positioned by the clamping plate, and the speed sensor can be limited by the limit block, so that the speed sensor can be installed on the outer wall of the housing body more firmly, and the speed sensor is installed on the outer wall of the housing body parallel to the motor axis, which can save space on the rear cover;

[0016] When the speed sensor needs to be disassembled, the screw is rotated. Through the action of the threaded structure, the bottom block can rise along the screw, so that the base can drive the speed sensor to rise between the two clamping plates. When the rising force is greater than the elastic force of the spring, the limit block can compress the spring, so that the speed sensor can be disengaged between the two clamping plates, making it easier to assemble the speed sensor.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] See also Figure 1 , a motor housing that saves installation space, comprising a housing body 1 and a speed sensor 2, wherein the speed sensor 2 is installed outside the housing body 1;

[0026] The speed sensor 2 is installed on the outer wall of the casing body 1 in parallel with the motor axis, which can save space on the rear cover.

[0027] Embodiment 2

[0028] See also Figure 1-5 , two clamping plates 3 are symmetrically arranged on the outer wall of the casing body 1, a base 4 is arranged between the two clamping plates 3, the speed sensor 2 is located above the base 4, a bottom block 7 is fixedly arranged at one end of the base 4, a screw 5 is rotatably arranged on the outer wall of the casing body 1, the screw 5 passes through the bottom block 7, and the screw 5 is threadedly connected with the bottom block 7, a cavity 9 is arranged on the top of the clamping plate 3, a spring 10 is arranged inside the cavity 9, and a limit block 8 for limiting the speed sensor 2 is arranged at one end of the spring 10. In this structure, the speed sensor 2 is fixed on the outer wall of the casing body 1, the speed sensor 2 can be positioned by the clamping plate 3, and the speed sensor 2 can be limited by the limit block 8. At this time, the spring 10 is in a normal state, which can make the speed sensor 2 more firmly installed on the outer wall of the casing body 1;

[0029] When the speed sensor 2 needs to be disassembled, the screw 5 is rotated. Through the action of the threaded structure, the bottom block 7 can rise along the screw 5, so that the base 4 can drive the speed sensor 2 to rise between the two clamping plates 3. When the rising force is greater than the elastic force of the spring 10, the limit block 8 can compress the spring 10, so that the speed sensor 2 can be disengaged between the two clamping plates 3, making it convenient to assemble the speed sensor 2.

[0030] In this structure, the limit block 8 is a trapezoidal structure, and the limit block 8 with a trapezoidal structure can facilitate the assembly of the speed sensor 2.

[0031] The lack of a force point on the screw rod 5 will make the screw rod 5 difficult to operate. A toggle block 6 is provided at the top of the screw rod 5. The toggle block 6 can provide a force point on the screw rod 5, making the screw rod 5 easy to operate.

[0032] Furthermore, the clamping plate 3, the limiting block 8, the base 4 and the screw 5 are all made of metal.

[0033] In this structure, an anti-skid pad is provided at the upper end of the base 4. The anti-skid pad can increase the friction between the speed sensor 2 and the base 4, so that the speed sensor 2 can be installed more firmly.

[0034] In the description of this article, it should be noted that relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
