Description

Technical Field

[0001] This utility model relates to the field of electronic parking brake technology, and in particular to a box cover structure and an electronic parking brake actuator having the same. Background Technology

[0002] The electronic parking brake actuator includes a motor and a transmission mechanism. Traditional mechanisms reduce the motor's output speed while increasing the output torque transmitted to the brake caliper to achieve the parking function. Currently, the connector for the existing electronic parking brake actuator, which interlocks with the client's connector, is located on the actuator's housing. The motor within the actuator is typically connected via lead wires or resistance welding to the motor terminals using conductive terminals. However, due to limitations imposed by the client's environment, the connector's location is not fixed, preventing different projects from sharing the same housing mold. This necessitates the development of new housing molds, leading to higher costs. Furthermore, the use of lead wires or resistance welding for the electronic parking brake actuator results in low assembly efficiency and a risk of connection loosening due to long-term vibration during vehicle operation.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Figure 1 This diagram shows a structural schematic of an electronic parking brake actuator provided in an embodiment of the present invention. Figure 2 This diagram shows a cross-sectional view of an electronic parking brake actuator provided in an embodiment of the present invention.

[0027] Reference Figure 1 and Figure 2 The electronic parking brake actuator of this utility model embodiment includes a housing 10, a motor 30 and a transmission mechanism (not shown) assembled in the housing 10, and a housing cover structure 20. The housing 10 includes a motor 30 receiving cavity for accommodating the motor 30 and a gear cavity for accommodating the transmission mechanism. The housing cover structure 20 covers the housing 10 and seals the housing 10.

[0028] The cover structure 20 includes a cover body 21 and a connector 22 disposed on the cover body 21. The connector 22 is used for electrical connection with the client. The connector 22 includes a connector housing (not shown) and connector terminals (not shown) located within the connector housing. The connector 22 can be configured according to the client's installation requirements, such as being positioned above the cover body 21 or on the side of the cover body 21. The orientation of the connector 22's insertion interface can also be designed according to requirements. The cover structure 20 also includes a peripheral side extending downward around the periphery of the cover body 21. The peripheral side and the mounting surface of the housing 10 are stepped. The mounting surface of the housing 10 has a stepped structure that matches the stepped surface, thus achieving a sealed assembly between the cover structure 20 and the housing 10.

[0029] Furthermore, the cover structure 20 also includes a first conductive terminal 23 and a second conductive terminal 24, which are used to connect the motor 30 and the connector 22 for current conduction. Specifically, the first conductive terminal 23 includes a first conductive body 231, a first connecting end 232 and a second connecting end 233 located at both ends of the first conductive body 231, and the second conductive terminal 24 includes a second conductive body 241, a third connecting end 242 and a fourth connecting end 243 located at both ends of the second conductive body 241.

[0030] The first conductive body 231 and the second conductive body 241 are disposed inside the cover body 21. The first connecting end 232 and the third connecting end 242 are electrically connected to the connector terminal, respectively. The second connecting end 233 and the fourth connecting end 243 extend from the bottom of the cover body 21 and are electrically connected to the motor 30. The first conductive terminal 23 and the second conductive terminal 24 are integrally formed from conductive material.

[0031] The distance between the first connecting end 232 and the third connecting end 242 is smaller than the distance between the second connecting end 233 and the fourth connecting end 243. Through the structural design of the first conductive terminal 23 and the second conductive terminal 24, one end of each terminal can be connected to the connector 22, and the other end can be electrically connected to the motor 30.

[0032] In one embodiment, the second connecting end 233 and the fourth connecting end 243 have a fork-shaped structure. In this embodiment, in the opposite direction of the second connecting end 233 and the fourth connecting end 243, the two clamping terminals of the second connecting end 233 are arranged opposite each other, and the two clamping terminals of the fourth connecting end 243 are also arranged opposite each other. Furthermore, limiting protrusions are provided at the free ends of the oppositely arranged clamping terminals, thereby further improving the reliability of the insertion.

[0033] In this embodiment, when the cover structure 20 is assembled to the housing 10, the second connecting end 233 and the fourth connecting end 243 are respectively inserted into the electrical connection part 31 of the motor 30, which is a metal sheet structure. This embodiment achieves electrical connection through direct insertion during assembly, eliminating the need for additional leads or welding, thus improving the assembly efficiency of the cover and housing 10. By adapting the connector 22 on the cover, it can meet the installation requirements of different clients, thereby ensuring the housing of the electronic parking brake actuator meets the requirements of versatility and saving mold costs. Of course, in other embodiments, the second connecting end 233 and the fourth connecting end 243 can also be configured as an elastic clamping shape, connecting directly to the electrical connection part of the motor 30 through insertion.

[0034] In this embodiment of the invention, the second connecting end 233 and the fourth connecting end 243 are respectively disposed on opposite sides of the cover body 21, and the second end and the fourth end correspond to the upper part of the motor 30 receiving cavity. The first conductive body 231 is bent outward relative to the first connecting end 232, and the second connecting end 233 is bent downward relative to the first conductive body 231. The second conductive body 241 is bent outward relative to the second connecting end 233, and the fourth connecting end 243 is bent downward relative to the second conductive body 241. This arrangement makes the first conductive body 231 and the second conductive body 241 form a V-shape. Specifically, the first conductive body 231 and the second conductive body 241 are arranged according to the structure of the top surface of the cover body 21. For example, if the top surface of the cover body 21 is a slope, then the first conductive body 231 and the second conductive body 241 are inclined along the slope. The first conductive body 231 and the second conductive body 241 are injection molded into the cover body 21.

[0035] Furthermore, the first connecting end 232 is connected to one of the connector terminals by plug-in connection or integral molding, and the third connecting end 242 is connected to another connector terminal by plug-in connection or integral molding. The specific design method can be adjusted according to the application environment or design requirements, and is not specifically limited here.

[0036] The cover structure and electronic parking brake actuator provided by this utility model, by placing conductive terminals inside the cover and adapting them for electrical connection with connectors and motors, and by adjusting the position of the connectors to meet the installation requirements of different clients, makes the housing of the electronic parking brake actuator universal and improves the assembly efficiency of the electronic parking brake actuator. Furthermore, the end of the conductive terminal is set as a fork-shaped structure, so that during cover installation, the conductive terminal is simultaneously connected to the electrical connection part of the motor through a plug-in method, ensuring assembly reliability while improving assembly efficiency.

[0037] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
