Description

The present invention relates to a motor and a motor brake device having a concavo-convex structure, and more particularly to a motor and a motor brake device that can be quickly and simultaneously fixed and positioned at the time of assembly.

In view of driving safety, many vehicles are currently equipped with an anti-lock braking system (Anti-lock Braking System). The anti-lock braking system has the ability to control the braking movement of the wheels, and by adjusting the braking force in the event of an emergency while driving or when the road surface environment is not good, the tire's braking force can be adjusted. It is possible to avoid the loss of control of the vehicle due to locking or slipping.

In general, an anti-lock braking system is a vehicle under various conditions by adjusting the braking force by combining or coordinating software (for example, an arithmetic program), hardware (for example, a control device) and a transmission mechanism. It is possible to enhance the maneuverability of. Currently, in anti-lock braking systems, it is the mainstream to use a hydraulic device as a transmission mechanism. However, the hydraulic system for an anti-lock braking system usually has a plurality of parts / members, requires a large number of steps at the time of assembly, and has a high demand for sealing performance. Therefore, welding is a general means of adhesion and sealing.

However, although welding makes it easy to construct complicated joint surfaces of parts and members, it lacks seismic resistance and high temperature resistance. On the other hand, in a hydraulic system equipped with a motor or a pump, vibration and hot air are generated during operation, and therefore, after a long period of time, the sealing performance of the parts / members in the hydraulic system may gradually weaken. In particular, when sudden braking is applied in an emergency during operation, the vibration and high temperature generated in the hydraulic system during high-speed operation cause direct tearing and separation of welded parts and members, resulting in an anti-lock braking system. There is a risk of loss of function.

On the other hand, the motor must withstand a large force as the main power source for driving the hydraulic system. In particular, since stress and vibration are generated during operation, it is necessary to arrange them closely in the hydraulic system. In the well-known assembly and fixing method, the motor is mainly mounted in the base and then tightened with screws or welded to fix the motor in the hydraulic system. However, tightening with screws requires time and labor because the screw holes need to be aligned. Welding is also difficult to control quality and affects both manufacturing cost and product quality.

Therefore, in order to eliminate the defects of the prior art, the motor and the motor brake device having the uneven structure in the embodiment of the present invention have unevenness on the motor of the motor brake device so that they can be easily coupled to the main body of the motor brake device. The structure is provided, and the motor is sealed in the main body by a crimping method. As a result, it becomes possible to avoid assembling and sealing by welding for the motor of the motor brake device, and the assembling time is reduced. In addition, the uneven structure of the motor has a high coefficient of friction in the coupling region and can be used simultaneously for positioning the motor and regulating the direction and rotational displacement of the motor. This prevents the rotation or displacement of the motor during operation, and thus the influence on other parts / members.

Based on at least one of the above objectives, the embodiments of the present invention provide a motor having a concavo-convex structure. The motor includes a motor assembly, a housing with an arcuate outer surface, and a concavo-convex structure provided on the arcuate outer surface of the housing. The motor assembly is provided inside the housing. The arcuate outer surface is divided into a first region and a second region. The concavo-convex structure is located in the first region and is installed on the arcuate outer surface so as to surround it. The uneven structure is composed of a micro three-dimensional structure.

Optionally, the first region has a higher coefficient of friction than the second region. The first region is a rough surface and the second region is a smooth surface.

Optionally, the first region is a long region that surrounds the arcuate outer surface. In the micro three-dimensional structure, an irregular pattern is formed in the first region to form an uneven structure. The area of the first region is smaller than the area of the second region, and the first region is close to the bottom of the housing.

Optionally, the first region is a long region that surrounds the arcuate outer surface. In the micro-three-dimensional structure, a regular pattern is formed in the first region to form a concavo-convex structure. The area of the first region is smaller than the area of the second region, and the first region is close to the bottom of the housing.

Optionally, the concavo-convex structure is integrally molded into the housing. Alternatively, the concave-convex structure is installed so as to adhere to the arcuate outer surface of the housing. For example, the concave-convex structure is formed on the arc-shaped outer surface of the housing by processing.

Optionally, the plurality of micro-three-dimensional structures constitutes a particular character or pattern. That is, the plurality of micro-three-dimensional structures are represented by specific characters or patterns.

Based on at least one of the above objectives, embodiments of the present invention provide a body having a first mounting groove and a motor brake device comprising the above motor. The motor is fixedly installed in the first installation groove.

Optionally, the motor brake device further includes a braking assembly. The braking assembly is fixed in the body and is ubiquitously connected to the motor.

Optionally, the hardness of the body is less than the hardness of the motor housing. The arcuate outer surface of the motor housing is firmly in close contact with the inner wall of the first installation groove of the main body.

Optionally, the motor brake device is an anti-lock brake device and the braking assembly is a drainage pump.

To put it simply, the motor and the motor brake device having the uneven structure provided in the embodiment of the present invention use the uneven structure of the motor itself to simplify the combination relationship with the main body of the motor brake device. As a result, the assembly process can be reduced and sealing by welding can be avoided. Therefore, it has strengths in various markets (for example, vehicle makers, motorcycle makers, ABS makers, etc.) in which there is a need for motor brake devices such as anti-lock brake devices.

In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail below through the following specific examples and in combination with the accompanying drawings.

The embodiments of the present invention provide a motor braking device including a main body, a motor and a braking assembly. The body has a plurality of communicating installation grooves for installing the motor and the braking assembly, respectively. The motor has an uneven structure that can be coupled to the installation groove in the main body. Also, the braking assembly is communicably connected to the motor through an communicating installation groove. Since both the motor and the braking assembly have a combined structure that engages with the installation groove of the main body, the connection between each component / member in the motor braking device and the main body becomes more solid after assembly. It is also possible to simplify the assembly process.

First, refer to FIG. FIG. 1 is a schematic view of a motor brake device according to an embodiment of the present invention. As shown in FIG. 1, the motor brake device 1 (for example, an anti-lock brake device, but not limited to this) in the embodiment of the present invention is basically composed of an electronic component E and a mechanical component M. , The whole appearance is almost hexahedron. Of these, since the length of the electronic component E is slightly longer than that of the mechanical component M, the upper half of the side surface of the motor brake device 1 protrudes from the lower half (or the lower half has a notch). ing). FIG. 2 is a schematic view of the case where the electronic component E is removed from the motor brake device according to the embodiment of the present invention. As shown in the figure, the mechanical component M includes a main body 10, a motor 20, and a braking assembly 40 (for example, an oil drainage pump, but not limited to this).

Subsequently, reference is made to FIG. FIG. 3 is an exploded view of the motor brake device according to the embodiment of the present invention. As shown in the figure, the electronic component E of the motor brake device 1 in the embodiment of the present invention can be an electronic control unit 100. The electronic control unit 100 is electrically connected to the motor 20 to control the operation of the motor 20. In one embodiment, the electronic control unit 100 is a microcontroller and the motor 20 is a servomotor. However, in the present invention, the types of the electronic control unit 100 and the motor 20 are not limited to these. Further, the connection relationship between the electronic control unit 100 and the motor 20 is not limited, and it is sufficient that these operations can be controlled. The electronic control unit 100 includes an upper cover 110, a control panel 120, and a unit main body 130. The upper cover 110, the control panel 120, and the unit main body 130 form a substantially rectangular parallelepiped after being laminated and combined. A space is provided in the unit main body 130, and it is possible to cover and accommodate the motor 20 protruding from the main body 10 after being mounted on the main body 10 after assembly.

As shown in FIG. 3, the appearance of the main body 10 is substantially hexahedron, and the upper surface 1011 is provided with a first installation groove 11 for assembling the motor 20. Further, the first side surface 1012 of the main body 10 is provided with a second installation groove 13 for assembling the braking assembly 40. The motor 20 is assembled in the first installation groove 11 in a direction in which the axis is perpendicular to the upper surface 1011 of the main body 10. The braking assembly 40 is assembled in the second installation groove 13 in a direction in which the axis is parallel to the upper surface 1011 and perpendicular to the first side surface 1012. Therefore, the axis of the motor 20 and the axis of the braking assembly 40 are orthogonal to each other on the direction line. By arranging in this way, the space inside the main body 10 can be used to the maximum while maintaining the functions of each part / member, and the volume of the entire motor brake device is reduced.

In addition, refer to FIG. FIG. 4 is a cross-sectional view of the motor brake device according to the embodiment of the present invention. As shown in the figure, the mechanical component M further includes a rotating assembly 80 and a bearing 90 assembled in the third installation groove 17 of the main body 10. The first installation groove 11 and the second installation groove 13 communicate with each other via the third installation groove 17. That is, the third installation groove 17 is located between the first installation groove 11 and the second installation groove 13. The rotation assembly 80 is connected to the braking assembly 40 provided in the second installation groove 13 and the motor 20 provided in the first installation groove 11. The motor 20 drives the rotating assembly 80 to operate the braking assembly 40. The bearing 90 is arranged between the rotating assembly 80 and the motor 20. A part of the bearing 90 is located in the first installation groove 11. In one embodiment, the rotating assembly 80 is an eccentric ring and the bearing 90 is a ball bearing. Moreover, the bearing 90 is provided in the third installation groove 17 by a tightening method. The outer surface of the portion of the bearing 90 located in the third installation groove 17 is firmly in close contact with the inner wall of the third installation groove 17. However, the present invention does not limit the type and arrangement method of the assembly to this.

Refer to FIGS. 5 and 6 which are schematic views before and after assembly of the motor and sectional views after assembly in the embodiment of the present invention. The motor 20 has a columnar shape and has a housing 21. Further, a motor assembly 25 (including a general motor circuit, a stator, a rotor, etc., the type of the motor assembly does not limit the present invention) is provided in the housing 21. The outer surface of the housing 21 is divided into a first region 211 and a second region 212. The concave-convex structure 22 is provided in the first region 211. The concave-convex structure 22 is composed of a plurality of micro-three-dimensional structures and surrounds the outer surface of the housing 21. The concave-convex structure 22 installed in the housing 21 so as to surround the housing 21 utilizes the distribution of the micro-three-dimensional structure to increase the coefficient of friction in the first region. As a result, when the motor 20 is joined to the main body 10, the motor 20 is fixedly installed in the first installation groove 11 by utilizing the uneven structure 22. Further, rotation and movement in the first installation groove 11 during operation of the motor 20 are prevented.

Therefore, the coefficient of friction of the first region 211 is higher than the coefficient of friction of the second region 212. That is, relatively, the first region 211 is a rough surface and the second region 212 is a smooth surface.

In one embodiment, the concave-convex structure 22 of the motor 20 is a micro-three-dimensional structure formed in the first region 211 on the outer surface of the housing 21 by direct processing using a tool. For example, a micro-three-dimensional structure is formed by engraving, etching, brush finishing, or the like. Therefore, the concave-convex structure 22 and the housing 21 of the motor 20 have the same material. However, the present invention does not limit the material and forming method of the concave-convex structure 22 to this, and may be integrally molded with the housing 21, or may be separately formed and / or added to the housing 21 by another processing method. .. Furthermore, the micro-three-dimensional structure is not limited to the design for the purpose of fixing, and a specific character or pattern may be shown as a model number display of the product supply source or the motor. In other embodiments, the concave-convex structure 22 may adhere the micro-three-dimensional structure to the outer surface of the housing 21 by sandblasting or film bonding. Further, the material of the sandblast and the material of the film may be the same as or different from the material of the housing.

Specifically, the housing 21 of the motor 20 has an arcuate outer surface, and the first region 211 is a long region surrounding the housing 21. Further, the plurality of micro-three-dimensional structures of the concave-convex structure 22 are spread over the entire first region 211. In this embodiment, the first region 211 is close to the bottom of the housing 21 so as to be easily coupled to the first installation groove 11 of the main body 10. Moreover, the first region 211 occupies only a small part of the outer surface of the housing 21, and is smaller than the area of the second region 212. The concave-convex structure 22 has a plurality of micro-three-dimensional structures arranged continuously or intermittently, and can show an arrangement pattern in a plan view. As the pattern, as shown in FIGS. 7A to 7D, a regular type or an irregular type can be used. The pattern of FIG. 7A is a regularly continuous mesh-like pattern having an acute angle. The pattern of FIG. 7B is a regular and intermittent wavy pattern and does not have an acute angle. Further, FIG. 7C is an irregular and intermittent convex point / convex grain pattern, and FIG. 7D is an irregular and continuous fold pattern. The present invention does not limit the shape and type of the concave-convex structure 22 to this, but preferably a pattern having no directionality. The plurality of micro-three-dimensional structures of the uneven structure 22 may be uniformly spread in the first region 211 or may be unevenly distributed in the first region 211.

In addition, the first installation groove 11 of the main body 10 also has an arc-shaped inner wall so as to easily accommodate the motor 20. Further, the circumference or diameter of the inner wall of the first installation groove 11 is substantially equal to the circumference or diameter of the outer surface of the housing 21 in the motor 20. By doing so, the outer surface of the housing 21 of the motor 20 can be firmly brought into close contact with the inner wall of the first installation groove 11 of the main body 10. Due to the high coefficient of friction of the concave-convex structure 22 located in the first region 211, the outer surface of the housing 21 of the motor 20 does not move with respect to the inner wall of the first installation groove 11. In this embodiment, the main body 10 can position the motor 20 only by accommodating the lower half of the motor 20. However, the present invention does not limit the size of the accommodation space of the main body to this.

Therefore, when assembling the motor 20 to the main body 10, it is only necessary to insert the motor 20 into the first installation groove 11 and then crimp the motor 20 and the main body 10 (preferably by tightening or interfering). The motor 20 can be fixed in the first installation groove 11. In one embodiment, the main body 10 is an aluminum cavity and its hardness is smaller than that of the housing 21 of the motor 20. However, in this embodiment, the hardness and material of the main body 10 and the housing 21 are not limited to this.

As shown in FIG. 6, the third installation groove 17 is located below the first installation groove 11 and has a diameter smaller than that of the first installation groove 11. The rotating shaft 23 of the motor 20 penetrates the rotating assembly 80 and the bearing 90 located in the third installation groove 17 to operate the rotating assembly 80. As described above, the bearing 90 is partially located in the third installation groove 17 and partly in the first installation groove 11. The bearing 90 of the portion located in the first installation groove 11 is substantially in contact with the lower surface of the motor 20 and is housed in the housing 21 of the motor 20. Specifically, the outer surface of the bearing 90 can be divided into an upper half portion and a lower half portion, and the upper half portion firmly adheres to the inner wall of the housing 21 of the motor 20 while the lower half portion is a third installation groove 17. Firmly adheres to the inner wall of the. The arrangement of the bearings 90 distributes the load applied to the rotating assembly 80 and the motor 20 when the motor brake device 1 is in operation. Further, the heat dissipation effect can be improved by the overall arrangement of the motor 20 and the main body 10.

Subsequently, the flow of assembling the motor brake device described in the embodiment of the present invention will be described. First, the bearing and the rotating assembly are assembled in the third installation groove of the main body provided with a plurality of communication grooves. The bearing and the rotating assembly are arranged in the third installation groove so that they overlap coaxially. Also, the bearings are located above the rotating assembly. The third installation groove is located below the first installation groove and communicates with the first installation groove and the second installation groove. Moreover, the bearing, the rotating assembly and the motor are interlocked in the structure and the transmission function. Therefore, in one embodiment, the bearing and the rotation assembly are first assembled to the motor, and then the bearing and the rotation assembly are mounted together with the motor into the installation groove of the main body. However, the present invention is not limited to this.

Subsequently, the motor is inserted into the first installation groove on the upper surface of the main body and crimped. As a result, the motor is fixed in the first installation groove of the main body by utilizing the uneven structure of the outer surface of the housing. Since the contour of the first installation groove is similar to the shape of the motor, the housing of the motor can be firmly attached to the inner wall of the first installation groove.

Then, the braking assembly is assembled in the second installation groove on the first side surface of the main body. Since the second installation groove communicates with the first installation groove, the braking assembly is mobilably connected to the motor. The transmissible connection means that the motor drives the rotating assembly during operation via a member arrangement (eg, but not limited to, bearings and rotating assembly) between the motor and the braking assembly. , Indirectly actuating the braking assembly.

Finally, the electronic control unit is assembled on the upper surface of the main body to cover the portion of the motor protruding from the upper surface of the main body. This completes the assembly of the motor brake device.

Summarizing the above, the technical effects of the motor and the motor brake device having the uneven structure described in the embodiment of the present invention are as follows, as compared with the prior art.

In the prior art, a plurality of parts / members of a motor brake device have been fixed and sealed by welding or tightening with screws. However, the quality of welding directly affects the sealing performance of parts and members. Moreover, since the welded contacts lack vibration resistance and high temperature resistance, there are safety concerns when the motor brake device is operated. Further, in the case of tightening with screws, the manufacturing time and cost increase. On the other hand, the motor brake device described in the embodiment of the present invention simplifies the combination relationship by utilizing the structure of the parts / members, and is desired by the crimping technique without using the welding or screw tightening method. Positioning and fixing can be achieved. As a result, the parts / members are not damaged or torn due to the vibration caused by the high-speed operation and the high temperature, and the assembly process to the main body can be reduced, so that the assembly efficiency is improved.

In the above, the present invention has been disclosed by preferred embodiments, but those skilled in the art should understand that the above embodiments are merely for explaining the present invention and are construed to limit the scope of the present invention. should not do. It should be noted that any modifications and substitutions equivalent to the above embodiments should be considered to be within the scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of claims for utility model registration.
