Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle door actuators. Specifically, this utility model relates to an actuator sealing and protection structure and an actuator assembly. Background Technology

[0002] Automobiles are a common means of transportation in people's lives today, playing an irreplaceable role in the development of modern society. As people's demands for convenience and comfort in automobiles continue to increase, the degree of electrification of vehicle body components is also increasing. Examples include electric doors, electric rearview mirrors, electric spoilers, and electric fuel tank caps. These electric body components all rely on motor-driven actuators to complete specific tasks. Because the motor and actuator are electrically driven, the requirements for the insulation and waterproofing performance of the entire vehicle are constantly increasing. In electric doors, since most doors involve rotational movement, the process of the actuator opening or closing the door is dynamic, with an arc-shaped trajectory. This necessitates a relatively large gap between the actuator housing and the connecting rod actuator components. Water and foreign objects can easily enter the actuator through these gaps, potentially damaging it. Figure 5 As shown, in the prior art, the linkage actuator is generally not protected, or is simply protected by foam, resulting in poor sealing, which affects the operation of the actuator and reduces its service life.

[0003] To address the aforementioned problems, patent document 218152592U discloses a housing sealing mechanism for an electric actuator, belonging to the field of electric actuator technology. It includes an actuator body, a fixed base mounted on the top of the actuator body, a rotating disk on one side of the actuator body, and a motor housing on the other side of the actuator body. A sealing and fixing mechanism is provided between the actuator body and the motor housing, and the sealing and fixing mechanism includes a first connecting plate. This invention, by setting up a sealing and fixing mechanism, a clamping and fixing mechanism, and a fastening assembly, clamps the first connecting plate and improves the fixing effect between the first and second connecting plates through a screw and a threaded sleeve, thereby improving the clamping degree between the first and second connecting plates and the sealing gasket. However, it cannot solve the aforementioned problems. Utility Model Content

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0025] Figure 1 This is a schematic diagram of the actuator sealing and protection structure in an embodiment of this utility model.

[0026] like Figure 1As shown, the actuator sealing and protection structure provided by this utility model includes a mounting bracket 10 and a sealing cover 20 disposed on the mounting bracket 10. The mounting bracket 10 is disposed on the vehicle body and is used to fix the sealing cover 20. The sealing cover 20 is disposed on the actuator 30, which can improve the sealing effect of the actuator 30. While improving the sealing performance, the sealing cover 20 can provide clearance space for the linkage actuator component inside the actuator 30, without interfering with the movement of the linkage actuator component. This makes the actuator sealing and protection structure provided by this utility model suitable for the scenario of opening or closing electric vehicle doors, thus improving the reliability of the structure.

[0027] like Figure 1 As shown, the mounting bracket 10 is provided with a mounting slot 11 that is adapted to the sealing cover 20. One end of the sealing cover 20 is locked in the mounting slot 11, thereby fixing the sealing cover 20 through the mounting bracket 10, preventing the sealing cover 20 from falling off during use, thereby improving the reliability of the structure and ensuring the sealing performance of the sealing cover 20.

[0028] Mounting bracket 10 is installed on the door 1. Mounting bracket 10 is also provided with arc-shaped grooves 12. The arc-shaped grooves 12 are evenly distributed on the edge of mounting bracket 10. The mounting bracket 10 can be locked onto the door sheet metal part through the arc-shaped grooves 12, thereby setting the mounting bracket 10 on the door 1, improving the stability of mounting bracket 10, further preventing the sealing cover 20 from falling off during use, thereby improving the reliability of the structure and ensuring the sealing performance of sealing cover 20.

[0029] The sealing cover 20 is tubular and made of rubber with high tear resistance, high aging resistance, and good high and low temperature resistance. One end of the sealing cover 20 is connected to the mounting slot 11 and fixed to the door 1, while the other end is connected to the vehicle body. The door 1 is folded and can be opened and closed on the vehicle body. The outer circumferential surface of the sealing cover 20 is provided with a pleated structure 21, which is evenly distributed on the sealing cover 20. The pleated structure 21 can realize the compression and stretching of the sealing cover 20. When the door is opened, the linkage actuator extends, and the sealing cover 20 is stretched as the door opens; when the door is closed, the linkage actuator retracts, and the sealing cover 20 is compressed as the door closes. The pleated structure 21 can effectively reduce the stress concentration of the sealing cover 20 under tension or compression, and greatly improve the fatigue life of the sealing cover 20.

[0030] This utility model also provides an actuator assembly, including an actuator sealing and protection structure and an actuator 30, which features long service life, reliable structure, and good sealing effect.

[0031] Figure 2 This is a schematic diagram of the actuator in an embodiment of this utility model; Figure 3 This is a schematic diagram of the actuator sealing and protection structure installed on the car door in an embodiment of this utility model.

[0032] like Figure 2 and Figure 3 As shown, the actuator 30 includes an actuator housing 31 and a connecting rod 32. The actuator housing 31 is mounted on the door 1. One end of the connecting rod 32 is movably inserted into the actuator housing 31, and the end of the connecting rod 32 away from the actuator housing 31 is connected to the vehicle body, thereby facilitating the motor to drive the actuator 30 to automatically open or close the door.

[0033] Figure 4 This is a schematic diagram of the actuator assembly installed on the vehicle body and door in an embodiment of this utility model.

[0034] The actuator housing 31 is provided with a second locking hole 33, and the mounting bracket 10 is provided with a first fastening hole 13 that matches the second locking hole 33. Screws are inserted into the first locking hole 13 and the second locking hole 33 to lock the mounting bracket 10 to the actuator housing 31. This allows one end of the sealing cover 20, which is engaged in the mounting slot 11, to be pressed against the actuator housing 31. The other end of the sealing cover 20 is connected to the vehicle body, forming a sealed cavity. This allows the end of the connecting rod 32, away from the actuator housing 31, to movably pass through the sealing cover 20 and the sealed cavity. When the door opens or closes, the connecting rod 32 extends and retracts within the sealing cover 20. Figure 4 As shown, this improves the sealing performance of actuator 30, effectively prevents water and impurities from entering the actuator, improves the reliability of the structure, and extends the service life of actuator 30.

[0035] The role and effect of the embodiments

[0036] The actuator sealing and protection structure provided by this utility model includes a mounting bracket 10 and a sealing cover 20 disposed on the mounting bracket 10. The mounting bracket 10 is disposed on the vehicle body and is used to fix the sealing cover 20. The sealing cover 20 is disposed on the actuator 30 and can improve the sealing effect of the actuator 30. While improving the sealing performance, the sealing cover 20 can provide clearance space for the linkage actuator component inside the actuator 30 and does not interfere with the movement of the linkage actuator component. This makes the actuator sealing and protection structure provided by this utility model suitable for the scenario of opening or closing electric vehicle doors, thus improving the reliability of the structure.

[0037] By screwing into the first locking hole 13 and the second locking hole 33, the mounting bracket 10 is locked and fixed to the actuator housing 31. This allows one end of the sealing cover 20, which is engaged in the mounting slot 11, to be pressed against the actuator housing 31. The other end of the sealing cover 20 is connected to the vehicle body, forming a sealed cavity. This allows the end of the connecting rod 32, away from the actuator housing 31, to movably pass through the sealing cover 20 and the sealed cavity. When the door opens or closes, the connecting rod 32 extends and retracts within the sealing cover 20. Figure 4As shown, this improves the sealing performance of actuator 30, effectively prevents water and impurities from entering the actuator, improves the reliability of the structure, and extends the service life of actuator 30.

[0038] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
