Description
Technical Field
[0001] This utility model relates to the field of electric regulator technology, specifically a waterproof and dustproof electric regulator. Background Technology
[0002] With the continuous development of automotive technology, the performance requirements for automotive comfort and safety are increasing. Various electric adjustment devices are used inside automobiles, such as electric adjusters for seats, windows, rearview mirrors, and headlights. These electric adjusters need to operate reliably under various complex environmental conditions. During vehicle operation, vehicles may encounter harsh environments such as rain, dust, and mud, thus placing higher demands on the waterproof and dustproof performance of electric adjusters. However, common electric adjusters often lack good sealing at their connecting points, allowing water and dust to enter the internal components during driving. This can lead to problems such as motor short circuits, damage to electronic components, and wear on the transmission mechanism, affecting the normal operation of the electric adjuster and reducing its reliability and lifespan. To reduce the frequency of failures, lower maintenance costs, and improve the overall quality and reliability of automobiles, the development of electric adjusters with waterproof and dustproof functions is imperative. Summary of the Invention
[0003] The purpose of this utility model is to provide a waterproof and dustproof electric regulator to solve the problem mentioned in the background art that the moving parts of the electric regulator are prone to water and dust ingress, leading to accelerated wear and short circuit damage.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and dustproof electric regulator, comprising a housing, a motor inserted into the outer surface of the housing, a top cover inserted into the outer surface of the housing, and a plug-in control board installed through the outer surface of the top cover, the plug-in control board being embedded in the inner side of the top cover, the plug-in control board being plugged into the motor, a mounting rod slidably mounted on the side of the housing away from the motor, the outer surface of the mounting rod being in contact with the outer surface of the housing, a sealing cover inserted into the outer surface of the housing, the outer surface of the sealing cover being penetrated by the mounting rod, and the outer surface of the mounting rod and the sealing cover being in sliding frictional connection.
[0005] Preferably, the outer surface of the top cover is evenly provided with holes, and the connection between the top cover and the outer shell is a protruding design. The side surface of the outer shell is evenly provided with hooks, and the hooks engage with the top cover. A sealing gasket is provided between the top cover and the outer shell, and the sealing gasket is respectively attached to the outer surface of the top cover and the outer shell. Fixing buckles are fixedly provided on both outer surfaces of the outer shell, and the fixing buckles engage with the outer shell of the headlight.
[0006] By adopting the above technical solution, the protruding design of the outer shell can effectively reduce the chance of rainwater flowing into the interior of the outer shell, allowing the outer shell and the top cover to be separated from each other. The hooks and the top cover can be connected and fixed to each other. At the same time, the concave design of the hooks makes it difficult for the top cover and the outer shell to detach. The setting of the sealing gasket can eliminate the gap between the outer shell and the top cover, improve the sealing performance of the outer shell and the top cover, and reduce the chance of water and dust entering the interior of the outer shell and causing damage.
[0007] Preferably, a first gear is fixedly installed at the output end of the motor, and the first gear does not fit against the outer surface of the housing. A first hook is fixedly installed inside the housing, and a second hook is fixedly installed inside the top cover. The second hook and the first hook are concentrically designed. A second gear is engaged on the outer surface of the second hook, and the diameter of the second gear is smaller than the diameter of the first gear. The first gear and the second gear mesh with each other, and the shaft of the second gear engages with the second hook.
[0008] By adopting the above technical solution, the engagement of the first hook and the second hook with the second gear can make the second gear more stable and secure when rotating, and can improve the connection strength of the top cover. At the same time, the diameter difference between the first gear and the second gear can also reduce the rotation speed of the second gear, allowing the installation rod to be more precise after it extends.
[0009] Preferably, a worm gear is rotatably mounted inside the housing, and a rotatable meshing mechanism is provided between the worm gear and the second gear.
[0010] By adopting the above technical solution, the headlight position will not shift due to vehicle movement and bumps after the mounting rod is moved by rotating the meshing mechanism.
[0011] Preferably, the rotating meshing mechanism includes a worm gear, which is fixedly mounted on the outer surface of the second gear, and the second gear and the worm gear are concentrically designed, with the worm wheel meshing with the worm gear.
[0012] By adopting the above technical solution, the rotation of the worm gear drives the meshing worm wheel to rotate together, which further reduces the rotation speed of the worm wheel, allowing the mounting rod to move out more slowly. The self-locking property of the worm wheel and worm gear locks the position of the mounting rod.
[0013] Preferably, a limiting post is fixedly installed on one outer surface of the top cover, and the limiting post is inserted into the mounting rod, the mounting rod is engaged with the limiting post, the limiting post and the mounting rod are slidably connected, and the mounting rod and the worm gear are threadedly connected.
[0014] By adopting the above technical solution, the limiting post can effectively restrict the mounting rod, preventing it from rotating along with the worm gear, thus allowing the mounting rod to be smoothly removed from the worm gear.
[0015] Preferably, a sealing plug is fitted onto the outer surface of the housing near the second gear. The outer surface of the second gear has a tightening hole, which is concentric with the second gear. The second gear and the sealing plug are concentric, and the outer surface of the sealing plug does not fit against the outer surface of the second gear.
[0016] By adopting the above technical solution, the sealing plug can block the outer shell, preventing external dust and water from entering the interior of the outer shell. When manual adjustment is required, simply open the sealing plug to expose the screw hole so that the tool can be inserted and rotated. This allows the rotating and adjusting parts to not pass through the outer shell, reducing the gap between the outer shell and external moving parts, and reducing the chance of water and dust entering the outer shell.
[0017] Compared with the prior art, the beneficial effects of this utility model are: the waterproof and dustproof electric regulator:
[0018] 1. When in use, the sealing cover fits tightly against the smooth outer surface of the mounting rod, effectively sealing the gap between the mounting rod and the housing. When the worm gear rotates and drives the mounting rod to move up and down, external dust and water will not be brought into the housing, reducing the occurrence of short circuits, accelerated wear and damage to the electric regulator caused by water and dust entering the housing.
[0019] 2. The second gear can be fixed by engaging the first hook with the second gear. At the same time, when the top cover and the outer shell are inserted together, the connection strength between the outer shell and the top cover can be strengthened by engaging the second hook with the second gear, which improves the stability after the outer shell and the top cover are inserted together. The sealing gasket can also eliminate the gap between the outer shell and the top cover, so that the worm gear is fixed while strengthening the connection strength between the outer shell and the top cover.
[0020] 3. When the electric adjuster is activated, the motor will drive the first gear to rotate, causing the second gear meshing with the first gear to rotate as well. The difference in diameter between the second and first gears allows the worm gear to rotate slowly. When manual adjustment of the headlight position is required, simply remove the sealing plug on one side of the housing to expose the tightening hole, then insert the tool and rotate it. The worm gear drives the meshing worm wheel to rotate, allowing the mounting rod to move up and down and push the headlight to change its angle. The self-locking property of the worm wheel and worm gear maintains the position of the mounting rod, and the sealing plug improves the sealing of the housing, preventing the mounting rod from changing its angle and thus the headlight angle from changing when the vehicle is moving.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-6 This utility model provides a technical solution: a waterproof and dustproof electric regulator, including a housing 1, a motor 3 inserted into the outer surface of the housing 1, a top cover 2 inserted into the outer surface of the housing 1, and a plug-in control board 4 inserted through the outer surface of the top cover 2, and the plug-in control board 4 is embedded in the inner side of the top cover 2. The plug-in control board 4 is plugged into the motor 3. A mounting rod 13 is slidably installed on the side of the housing 1 away from the motor 3, and the outer surface of the mounting rod 13 is in contact with the outer surface of the housing 1. A sealing cover 16 is inserted into the outer surface of the housing 1, and the outer surface of the sealing cover 16 is penetrated by the mounting rod 13. The outer surface of the mounting rod 13 and the sealing cover 16 are in sliding friction connection.
[0030] The electric adjuster can be snapped into place on the inner surface of the headlight by the fixing buckle 15. When the motor 3 is running, the mounting rod 13 will move up and down, allowing the mounting rod 13 to extend or retract from the housing 1. This allows the headlight angle connected to the mounting rod 13 to be adjusted. The smooth design of the outer surface of the mounting rod 13 reduces the gap between the mounting rod 13 and the housing 1. At the same time, the sealing cover 16 installed on the outer surface of the housing 1 can further eliminate the gap, preventing dust and water from entering the interior of the housing 1 and causing increased wear and short circuits, thus improving the service life of the electric adjuster.
[0031] The outer surface of the top cover 2 is evenly provided with holes, and the connection between the top cover 2 and the outer shell 1 is a protruding design. The side surface of the outer shell 1 is evenly provided with hooks 6, and the hooks 6 are engaged with the top cover 2. A sealing gasket 5 is provided between the top cover 2 and the outer shell 1, and the sealing gasket 5 is respectively attached to the outer surface of the top cover 2 and the outer surface of the outer shell 1. Fixing buckles 15 are fixedly provided on both outer surfaces of the outer shell 1, and the fixing buckles 15 are engaged with the outer shell of the headlight.
[0032] The sealing gasket 5 can eliminate the gap between the outer shell 1 and the top cover 2, improving the sealing performance of the electric regulator. The engagement of the top cover 2 through hole and the hook 6 can connect and fix the outer shell 1 and the top cover 2 to each other. Since the hook 6 is inside the top cover 2 after the engagement is completed, the top cover 2 and the outer shell 1 are not easy to open due to external force.
[0033] The output end of the motor 3 is fixedly mounted with a first gear 7, and the first gear 7 is not in contact with the outer surface of the housing 1. The inside of the housing 1 is fixedly mounted with a first hook 10, and the inside of the top cover 2 is fixedly mounted with a second hook 11. The second hook 11 and the first hook 10 are concentrically designed. The outer surface of the second hook 11 is engaged with a second gear 9, and the diameter of the second gear 9 is smaller than the diameter of the first gear 7. The first gear 7 and the second gear 9 mesh with each other, and the shaft of the second gear 9 engages with the second hook 11.
[0034] The first hook 10 facilitates the installation of the second gear 9. Simultaneously, the engagement of the second hook 11 with the second gear 9 ensures a more secure connection between the outer casing 1 and the top cover 2. This allows the motor 3 to rotate via the plug-in control board 4, enabling the first gear 7 to rotate and drive the meshing second gear 9 to rotate together. The difference in diameter between the second gear 9 and the first gear 7 reduces the rotational speed of the second gear 9, preventing damage due to excessive rotational speed.
[0035] A worm gear 12 is rotatably mounted inside the outer casing 1, and a rotational meshing mechanism is provided between the worm gear 12 and the second gear 9.
[0036] The rotation of the second gear 9 drives the worm 8 to rotate, causing the worm wheel 12, which meshes with the worm 8, to rotate together. Due to the characteristics of the worm wheel 12 and the worm 8, the rotation speed of the worm wheel 12 is further reduced.
[0037] The rotating meshing mechanism includes: a worm 8, which is fixedly mounted on the outer surface of the second gear 9, and the second gear 9 and the worm 8 are concentrically designed; and a worm wheel 12 meshes with the worm 8.
[0038] The self-locking property of the worm 8 and worm wheel 12 ensures that after the worm wheel 12 rotates and sends out the mounting rod 13, the position of the mounting rod 13 will not change due to vehicle movement or bumps.
[0039] A limiting post 14 is fixedly installed on one outer surface of the top cover 2, and the limiting post 14 is inserted into the mounting rod 13. The mounting rod 13 is engaged with the limiting post 14, and the limiting post 14 and the mounting rod 13 are slidably connected. The mounting rod 13 is threadedly connected to the worm gear 12.
[0040] By engaging the worm gear 12 with the limiting post 14, the worm gear 12 will not rotate along with the mounting rod 13 when it rotates, allowing the mounting rod 13 to move up and down along the direction of the limiting post 14.
[0041] A sealing plug 18 is fitted onto the outer surface of the outer casing 1 near the second gear 9. A tightening hole 17 is provided on the outer surface of the second gear 9. The tightening hole 17 and the second gear 9 are concentrically designed. The second gear 9 and the sealing plug 18 are concentrically designed. The outer surface of the sealing plug 18 does not fit against the outer surface of the second gear 9.
[0042] When the headlight position needs to be manually adjusted, simply remove the sealing plug 18 from one side of the housing 1 to expose one side of the second gear 9, allowing the tool to be inserted into the tightening hole 17. This allows the second gear 9 to be rotated by the tool, eliminating the need for the second gear 9 to penetrate the side surface of the housing 1. This eliminates the gap between the housing 1 and the second gear 9, reducing the chance of water and dust entering the electric regulator, which could lead to increased wear and damage.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
