Description

Technical Field

[0001] The utility model relates to the technical field of sealing and waterproof structures, in particular to a sealing and waterproof structure of an electronic parking brake assembly. Background Art

[0002] Currently in the market, most electronic parking brake assemblies are directly connected to the parking wire rope assembly, and half of them have no waterproof structure. For example, in the Chinese patent with patent number CN116001763A, the electronic parking brake assembly has no other waterproof structure, and its assembly is directly connected to the parking wire rope assembly without a waterproof structure. If water enters the parking wire rope assembly, it will cause the electronic parking brake assembly to fail and the entire mechanism cannot continue to work. There is also the Chinese patent with patent number CN201911230013.7, and in this patent, the electronic parking brake assembly is connected to the parking wire rope assembly to complete the parking and release functions of the entire vehicle. There is no waterproof structure design, and the entire mechanism will fail after water enters. Therefore, this type of assembly in the existing technology is prone to water ingress, causing the entire device to fail and be damaged. Therefore, to address this problem, there is a need for an improved sealing and waterproof structure of the electronic parking brake assembly. Utility Model Content

[0003] The purpose of the present utility model is to provide a sealing and waterproof structure of an electronic parking brake assembly to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a sealing and waterproof structure of an electronic parking brake assembly, comprising an electronic parking brake assembly, a protective cover being provided on one side of the electronic parking brake assembly, a pull rod being provided inside the protective cover, a parking wire rope assembly being fixedly provided at one end of the pull rod, an O-ring being provided between the electronic parking brake assembly and the protective cover, and an X-ring being fixedly provided between one side of the inner side of the protective cover and the pull rod.

[0005] Preferably, the pull rod is movably sleeved inside the X-shaped ring, and a movable seal is provided between the pull rod and the X-shaped ring. When in use, the pull rod needs to undergo a left-right translation relative movement relative to the X-shaped ring.

[0006] Preferably, a shaft sleeve is fixedly provided inside the protective sleeve, and the pull rod is movably sleeved inside the shaft sleeve, so that the stability of the pull rod when it moves left and right can be ensured by the shaft sleeve.

[0007] Preferably, the transmission part of the electronic parking brake assembly is fixedly connected to the pull rod; when the driver issues a parking command, the transmission part of the electronic parking brake assembly can drive the pull rod to move, thereby driving the parking wire rope assembly to move through the pull rod, thereby finally completing the parking operation.

[0008] Preferably, the O-ring and X-ring are both made of rubber material. The O-ring and X-ring made of rubber material can ensure a sealing effect when squeezed, and also have a sufficient service life to ensure a long-term sealing and waterproof effect of the device.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. This utility model uses an O-ring and an X-ring structure to form two sealing points. Sealing point 1 uses an O-ring for static sealing and sealing point 2 for dynamic sealing. The entire structure is enclosed within a protective cover, ensuring it can withstand certain impacts and provides a certain degree of protection. This has the advantages of high dust and water resistance, thereby extending the service life of the entire parking structure.

[0011] 2. This utility model incorporates a waterproof structure between the electronic parking brake assembly and the parking cable assembly. An internal pull rod connects the two systems for parking and releasing. During installation, the X-ring is inserted into the protective sleeve, the shaft sleeve is pressed into the protective sleeve, and the pull rod passes through the protective sleeve to connect the electronic parking brake assembly and the parking cable assembly. This overall device has a simple structure and a reliable layout. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-2The utility model provides a technical solution: a sealing and waterproof structure of an electronic parking brake assembly 1, comprising an electronic parking brake assembly 1, a protective cover 2 being provided on one side of the electronic parking brake assembly 1, a pull rod 5 being provided inside the protective cover 2, a parking wire rope assembly 6 being fixedly provided at one end of the pull rod 5, an O-ring 101 being provided between the electronic parking brake assembly 1 and the protective cover 2, and an X-ring 4 being fixedly provided between one side of the inner side of the protective cover 2 and the pull rod 5.

[0017] The pull rod 5 is movably sleeved inside the X-shaped ring 4, and a movable seal is provided between the pull rod 5 and the X-shaped ring 4. When in use, the pull rod 5 needs to move left and right relative to the X-shaped ring 4;

[0018] The protective sleeve 2 is fixedly provided with a shaft sleeve 3, and the pull rod is movably sleeved inside the shaft sleeve 3. The shaft sleeve 3 can ensure the stability of the pull rod 5 when it moves left and right;

[0019] The transmission part of the electronic parking brake assembly 1 is fixedly connected to the pull rod 5. When the driver issues a parking command, the transmission part of the electronic parking brake assembly 1 can drive the pull rod 5 to move, and the pull rod 5 can drive the parking wire rope assembly 6 to move, thereby finally completing the parking operation.

[0020] The O-ring 101 and the X-ring 4 are both made of rubber material. The O-ring 101 and the X-ring 4 made of rubber material can ensure a sealing effect when squeezed, and also have a sufficient service life to ensure a long-term sealing and waterproof effect of the device.

[0021] In the present application, after the waterproof structure is connected to the electronic parking brake assembly 1, the pull rod 5 of the transmission part is arranged inside the protective cover 2, and then a double seal is arranged between the pull rod 5 and the protective cover 2 to form two sealing points, which are respectively sealed by an O-ring 101 and an X-ring 4. The sealing point 1 is statically sealed and waterproof by the O-ring 101, and the sealing point 2 is dynamically sealed and waterproof by the X-ring 4. The operating structure and the sealing structure are inside the protective cover 2 to ensure that they can withstand a certain impact and have certain protective performance. When the electronic parking brake assembly is in operation, it drives the pull rod 5 to run axially, and the pull rod 5 pulls the parking wire rope assembly 6 to perform parking action. The waterproof structure can ensure that there is no risk of water ingress after the electronic parking brake assembly is connected to the parking wire rope assembly.

[0022] Here's how it works:

[0023] When the driver parks the car, the electronic parking brake assembly 1 operates, driving the pull rod 5 in the waterproof structure to move linearly. The pull rod 5 is connected to the parking wire rope assembly 6, driving the parking wire rope assembly 6 to move linearly, completing the parking and release actions.
