Description

Technical Field

[0001] The present invention relates to the technical field of vehicle braking, and in particular to an actuator housing assembly and a parking actuator. Background Art

[0002] The parking actuators currently on the market are designed with multiple interface orientations in mind to meet the needs of different customer vehicle models. Specifically, the interface orientations of the parking actuators are mainly divided into three types: straight, curved downward, and curved upward. These interface designs with different orientations are designed to ensure that the parking actuators can be smoothly installed in the corresponding positions of various vehicle models and effectively perform their functions, such as realizing the parking lock and release of the vehicle. Manufacturers usually independently develop parking actuators with different interface orientations, that is, produce three MGUs (motor generator units) with different interfaces. This diversified design enables the parking actuator to better adapt to different vehicle models and peripheral parts arrangements.

[0003] However, this diversified design under the existing technology also brings significant problems. Since molds need to be developed separately for parking actuators with three different interfaces, the number of molds developed has increased significantly. Each parking actuator with each interface requires at least one set of independent molds to ensure its production accuracy and quality, which directly leads to a significant increase in manufacturing costs. At the same time, the development cycle of the mold is relatively long, and each link from design to manufacturing to testing requires a lot of time and resources. Therefore, the development of MGUs with three different interfaces not only increases manufacturing costs, but also extends the development cycle of the entire product. In summary, the main problems brought about by the diversification of existing parking actuator interfaces are high manufacturing costs and long development cycles. Summary of the invention

Unless otherwise specified, "plurality" means two or more.

[0051] In this embodiment, in the prior art of the actuator housing assembly, in order to meet the installation requirements of the parking actuator in different orientations, it is usually necessary to develop a corresponding mold for each orientation, which leads to a significant increase in manufacturing costs and an extension of the development cycle. Specifically, the interface orientations of the parking actuator are diverse, such as straight, curved downward, and curved upward, and each orientation requires a specific housing structure to adapt. The traditional approach is to design and manufacture independent molds for each orientation, which not only increases the number and cost of mold development, but also lengthens the development cycle of the entire product due to the complexity of the mold design and manufacturing process. Therefore, in the design and manufacturing process of the actuator housing assembly, how to reduce the number of mold development, reduce manufacturing costs, and shorten the development cycle has become a technical problem that needs to be solved urgently. To this end, this embodiment discloses an actuator housing assembly.

[0052] like Figure 1 As shown, the actuator housing assembly includes: a drive housing unit 10, a first housing unit 20, a second housing unit 30, and a third housing unit 40.

Through such a structural design, the actuator housing assembly can be in the first state, the first channel is perpendicular to the second channel, the first channel is parallel to the third channel, and the two larger openings can be blocked, thereby improving the airtightness of the space where the wire harness exists, and further improving the protection effect of the wire harness. At the same time, through the detachable connection between the first housing unit 20, the second housing unit 30, and the third housing unit 40, in combination with the first avoidance opening 33 and the second avoidance opening 34, other state changes except the first state can be realized, thereby reducing the number of development molds, reducing manufacturing costs, and shortening the development cycle.

[0053] In other embodiments, the first clamping portion 22 , the second clamping portion 32 and the third clamping portion 42 may be made of magnetic materials or adhesive materials, such as magnets, adhesives, etc.

[0055] In this embodiment, if Figure 4 As shown, the actuator housing assembly also has a third state; the third state includes: the first channel, the second channel and the third channel are parallel in sequence; the first housing 21 is engaged with the second engaging portion 32; the second housing 31 is engaged with the third engaging portion 42; the first housing 21 blocks the first avoidance opening 33; the third housing 41 blocks the second avoidance opening 34. This state design makes the actuator housing assembly more versatile and can be switched between the first state, the second state and the third state, further reducing the cost of developing molds.

[0056] In this embodiment, if Figure 5 , Figure 6 As shown, the first housing unit 20 further includes a first limiting portion 25; when the actuator housing assembly is in the third state, the first limiting portion 25 can limit the second clamping portion 32 from being separated from the first housing 21; Figure 1 , Fig.10 As shown, the second housing unit 30 further includes a second limiting portion 35, a third limiting portion 36 and a fourth limiting portion 37; one side of the second housing 31 is the flip inner side, and the other side is the flip outer side; the flip inner side is arranged opposite to the flip outer side; the first avoidance opening 33 and the second avoidance opening 34 are both located on the flip inner side; the third limiting portion 36 and the fourth limiting portion 37 are located on the flip outer side; the third limiting portion 36 is arranged opposite to the first avoidance opening 33; the fourth limiting portion 37 is arranged opposite to the second avoidance opening 34; in the first state and the second state of the actuator housing assembly, the second limiting portion 35 can limit the third clamping portion 42 from being separated from the second housing 31, and the third limiting portion 36 can limit the first clamping portion 22 from being separated from the second housing 31; in the third state of the actuator housing assembly, the fourth limiting portion 37 can limit the fourth clamping portion 43 from being separated from the second housing 31. Such a design can improve the clamping stability between the first housing unit 20, the second housing unit 30, and the third housing unit 40, and ensure that the actuator housing assembly can operate stably in different states.

[0057] In this embodiment, if Figure 6As shown, the first housing unit 20 further includes a first guide portion 26, which includes a first guide segment 261, a second guide segment 262, a third guide segment 263 and a transfer guide segment 264; the second guide segment 262 and the third guide segment 263 are respectively parallel to the first channel; the transfer guide segment 264 is perpendicular to the second guide segment 262; one end of the transfer guide segment 264 is connected to the second guide segment 262, and the other end is connected to the third guide segment 263; one end of the first guide segment 261 points to the first housing 21, and the other end is connected to the transfer guide segment 264; as shown in FIG. Figure 1 , Figure 7 As shown, the second housing unit 30 further includes a first sliding portion 38; the first sliding portion 38 can be detachably connected to the second housing 31; the first sliding portion 38 can be slidably connected to the first housing 21; the first sliding portion 38 slides along the first guide portion 26.

Through such a design, the first sliding portion 38 can slide along the first guide section 26 by utilizing the limiting guide of the first guide section 26 to achieve the switching of the three states without disassembly, thereby improving the efficiency of state conversion.

[0058] In other embodiments, one end of the first guide section 261 points to the first housing 21, and the other end can be divided into a first path and a second path. The first path is connected to the end of the second guide section 262 away from the drive housing unit 10, and the second path is connected to the end of the third guide section 263 away from the drive housing unit 10. This can reduce the distance that the first sliding portion 38 moves to the transfer guide section 264, and the switching of the three states can be achieved more quickly, further improving the efficiency of state conversion.

This design utilizes the limiting guiding function of the second guide portion 39 to allow the second sliding portion 44 to slide along the second guide portion 39, further realizing the switching of the three states and improving the efficiency of the state conversion.

[0060] In other embodiments, Figure 8 As shown, the fourth guide section 391 may include a first guide groove 3911 and a second guide groove 3912. The first guide groove 3911, the second guide groove 3912, and the fifth guide section 392 are connected in sequence. The first guide groove 3911 is parallel to the fifth guide section 392. Alternatively, one end of the fourth guide section 391 is connected to the fifth guide section 392, and the other end extends obliquely in a direction away from the fifth guide section 392 and close to the sixth guide section 393. Thus, the moving distance of the second sliding portion 44 during state change can be reduced, and the efficiency of state change can be improved.

[0061] In this embodiment, if Figure 5 As shown, the first housing unit 20 further includes a plug 27; the plug 27 can be detachably connected to the first housing 21; the plug 27 can block the first wire hole 23 or the second wire hole 24.

[0062] In this embodiment, if Fig.12 As shown, the first housing unit 20 includes a first tensioning portion 28; the first tensioning portion 28 can be fixedly connected to the first housing 21; the first tensioning portion 28 is located in the first housing 21; there is a first harness space between the first tensioning portion 28 and the inner wall of the first housing 21; the second housing unit 30 includes a second tensioning portion 45; the second tensioning portion 45 can be fixedly connected to the third housing 41; the second tensioning portion 45 is located in the third housing 41; there is a second harness space between the second tensioning portion 45 and the inner wall of the third housing 41; the first tensioning portion 28 and the second tensioning portion 45 are both elastic. Through such a design, the elastic tensioning effect of the first tensioning portion 28 and the second tensioning portion 45 is utilized, so that during the state switching process, the harness can be kept in a taut and orderly state in the first harness space and the second harness space, thereby improving the rationality of the harness combing and avoiding the harness from being knotted or entangled.

Such a design enables the two groups of first tensioning parts 28 to be staggered, and the two groups of second tensioning parts 45 to be staggered, so that they can press each other's wire harnesses during elastic deformation, prevent the wire harnesses from falling out of the first wire harness space or the second wire harness space, and further improve the stability and safety of the wire harnesses.

[0064] In this embodiment, a parking actuator is disclosed. Figure 1 , Fig.12 As shown, the parking actuator includes: an actuator housing assembly of any one of the above embodiments, a drive unit, and a wiring harness unit 50. The drive assembly is located in the drive housing unit 10 of the actuator housing assembly; one end of the wiring harness unit 50 is electrically connected to the drive unit, and the other end of the wiring harness unit 50 passes through the drive housing unit 10, the first housing 21 of the actuator housing assembly, the second housing 31, and the third housing 41 in sequence and then exits.
