Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a waterproof and sealed improved automotive limiter. Background Technology

[0002] Door limiters are crucial components in automobiles, ensuring stable opening and closing of doors and limiting their opening angle. During daily use, door limiters are frequently exposed to various environmental factors, especially during rainy weather or vehicle washing, when they are easily exposed to water. Current door limiter technologies have several shortcomings in waterproofing and sealing. In common limiter structures, water can easily enter the limiter through installation gaps and gaps between moving parts. Once water enters, it corrodes internal metal components such as springs, sliders, and shafts, reducing the limiter's lifespan and affecting its normal limiting function. Furthermore, water mixing with the internal lubricating grease can disrupt lubrication, causing problems such as jamming and abnormal noises during operation, severely impacting the user experience. Therefore, developing a door limiter with excellent waterproof sealing performance, a reasonable structure, and controllable cost is of significant practical importance.

[0003] A Chinese patent with announcement number CN110924772B discloses an automobile door limiter. The key technical point of the solution is: by designing the limiting planes of the upper and lower limiting protrusions of the limiting arm, the upper and lower compression springs of the limiter work in different states during operation, causing the springs to fail and weaken at different times. Through the elastic force of the spring that fails slowly, the adjustment mechanism, through the compression of the second rack by the compression block, increases the pre-compression of the upper and lower compression springs, thereby reducing the degree of decrease in torque resistance after the limiter has been working for a long time.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: in narrow parking spaces, the car door may scrape against adjacent vehicles or walls due to excessive opening angle; in strong winds, the car door may be blown by the wind and hit obstacles, resulting in door deformation or damage to the limiter and the entry of dust, sand, rainwater and other impurities into the door hinge, causing jamming and abnormal noise; therefore, a waterproof and sealed improved car limiter is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art, such as car doors scraping against adjacent vehicles or walls due to excessive opening angle, and in strong winds, car doors may be blown by the wind and hit obstacles, resulting in door deformation or damage to the limiter, and the entry of dust, sand, rainwater and other impurities into the door hinges, causing jamming and abnormal noise. Therefore, a waterproof and sealed improved car limiter is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a waterproof and sealed improved automotive limiter, comprising a fixed plate, an adjusting device on one side of the fixed plate, the adjusting device comprising two clamping plates, both clamping plates being fixedly connected to one side of the fixed plate, a round rod being fixedly connected to the side of the two clamping plates that are close to each other, a limit plate being rotatably connected to the arc surface of the round rod, a plurality of grooves being formed on the surface of the limit plate, a hollow plate being slidably connected to the surface of the limit plate, a setting rod being slidably connected to the surface of the grooves, two L-shaped brackets being fixedly connected to one side of the hollow plate, the arc surface of the setting rod being aligned with the L-shaped brackets. The frame is slidably connected. A first spring is fixedly connected to the inner surface of the L-shaped frame. The other end of the first spring is fixedly connected to the arc surface of the setting rod. A protective device is provided on the surface of the limiting plate. The protective device includes a protective cover. The protective cover is slidably connected to the surface of the limiting plate. A circular hole is opened on the surface of the protective cover.

A second spring is fixedly connected to one side of the connecting plate. The other end of the second spring is fixedly connected to the inner surface of the setting groove.

[0007] The aforementioned components achieve the following effects: By setting up an adjustment device, the opening angle of the car door can be adjusted, preventing the car door from scraping against adjacent vehicles or walls due to excessive opening angle in narrow parking spaces. In some scenarios, temporary adjustments to the opening angle are required, and the lack of an adjustment function would limit the flexibility of the car door's use. This enhances the usability of the device. By setting up a protective device, the internal structure of the car door hinge is protected, preventing dust, sand, rainwater, and other impurities from entering the vicinity of the door hinge, which could cause the door to jam or make abnormal noises. The design holes in the protective structure enhance the sealing performance.

[0008] Preferably, four drive plates are fixedly connected to one side of the hollow plate, and two side plates are fixedly connected to the side where two drive plates are close to each other.

[0009] The effect achieved by the above components is to guide the movement trajectory of the setting rod in the left and right directions and ensure the sliding trajectory of the setting rod.

[0010] Preferably, the inner surfaces of the two setting rods are slidably connected to two insert rods, and both ends of the insert rods are fixedly connected to round blocks.

[0011] The effect achieved by the above components is that by setting the insertion rod, the vertical sliding trajectory of the two setting rods is positioned, ensuring the stability of the sliding trajectory of the setting rods.

[0012] Preferably, a positioning rod is slidably connected to the inner surface of the two plates, and the arc surface of the positioning rod is slidably connected to the limiting plate.

[0013] The effect achieved by the above components is that when the user needs to limit the door, the positioning rod is inserted into the inner surface of the limiting plate to ensure the stability of the door.

[0014] Preferably, a connecting plate is fixedly connected to the arc surface of the long rod, a second spring is fixedly connected to one side of the connecting plate, and the other end of the second spring is fixedly connected to the inner surface of the groove.

[0015] The effect achieved by the above components is that the elastic force of the second spring pushes the connecting plate to move, thereby automatically inserting the long rod into the inner surface of the round hole.

[0016] Preferably, a positioning plate is fixedly connected to the surface of the hollow board, and the positioning plate is slidably connected to the surface of the protective cover.

[0017] The effect achieved by the above components is that when the user assembles the protective cover, the surface of the protective cover abuts against the positioning plate, guiding the protective cover into the inner surface of the hollow plate.

[0018] In summary, the beneficial effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, the opening angle of the car door can be adjusted, avoiding the possibility that the car door may scratch adjacent vehicles or walls due to excessive opening angle in narrow parking spaces. In some scenarios, it is necessary to temporarily adjust the opening angle. Without the adjustment function, the flexibility of the car door would be limited. This device enhances the usability. By setting a protective device, the internal protection of the car door hinge is achieved, preventing dust, sand, rainwater and other impurities from entering near the car door hinge, which may cause the car door to jam or make abnormal noises.

[0021] Reference Figure 1 As shown, this utility model provides a technical solution: a waterproof and sealed improved car door limiter, including a fixed plate 1. An adjustment device 2 is provided on one side of the fixed plate 1. By setting the adjustment device 2, the opening angle of the car door can be adjusted, preventing the car door from scraping against adjacent vehicles or walls due to excessive opening angle in narrow parking spaces. In strong winds, the car door may be blown by the wind and hit obstacles, causing door deformation or damage to the limiter. In some scenarios, temporary adjustment of the opening angle is required; without adjustment, the flexibility of car door use would be limited. This invention enhances the usability of the device. The surface of the limiter plate 203 is provided with a protective device 3. By setting the protective device 3, the internal structure of the car door hinge is protected, preventing dust, sand, rainwater, and other impurities from entering near the door hinge. These impurities can increase friction in moving parts such as gears, racks, and pins, leading to surface wear, increased gaps, decreased positioning accuracy of the limiter, and phenomena such as door opening / closing jamming and abnormal noises. It may even cause parts to jam, affecting the normal opening and closing of the car door. The design holes of the protective structure enhance the sealing performance.

[0022] The specific settings and functions of its adjustment device 2 and protection device 3 will be described in detail below.

[0023] Reference Figure 2 and Figure 3As shown in this embodiment: the adjusting device 2 includes two clamping plates 201, both of which are fixedly connected to one side of the fixed plate 1. A round rod 202 is fixedly connected to the side of the two clamping plates 201 that is close to each other. A limiting plate 203 is rotatably connected to the arc surface of the round rod 202. Several grooves 204 are formed on the surface of the limiting plate 203. A hollow plate 205 is slidably connected to the surface of the limiting plate 203. A setting rod 206 is slidably connected to the surface of the grooves 204. Two L-shaped frames 207 are fixedly connected to one side of the hollow plate 205. The arc surface of the setting rod 206 is slidably connected to the L-shaped frame 207. A first spring 208 is fixedly connected to the inner surface of the L-shaped frame 207. The other end of the first spring 208 is fixedly connected to the arc surface of the setting rod 206. Four driving plates 210 are fixedly connected to one side of the hollow plate 205. Two side plates 209 are fixedly connected to the side of the two driving plates 210 that are close to each other. The guide rod 206 is positioned to ensure its sliding trajectory in the left and right directions. Two insert rods 211 are slidably connected to the inner surfaces of the two guide rods 206, with round blocks 212 fixedly connected to both ends of each insert rod 211. The insert rods 211 position the vertical sliding trajectory of the two guide rods 206, ensuring the stability of their sliding trajectory. Positioning rods 213 are slidably connected to the inner surfaces of the two clamping plates 201, with the arc surface of the positioning rods 213 slidably connected to the limiting plate 203. When the user needs to limit the movement of the door, the positioning rods 213 are inserted into the inner surface of the limiting plate 203 to ensure the stability of the door.

[0024] Reference Figure 4 and Figure 5 As shown, specifically, the protective device 3 includes a protective cover 31, which is slidably connected to the surface of the limiting plate 203. A circular hole 32 is formed on the surface of the protective cover 31. A mounting groove 33 is formed on the surface of the hollow plate 205. A long rod 34 is slidably inserted into the inner surface of the mounting groove 33, and a handle 35 is fixedly connected to the arc surface of the long rod 34. A connecting plate 36 is fixedly connected to the arc surface of the long rod 34. A second spring 37 is fixedly connected to one side of the connecting plate 36, and the other end of the second spring 37 is fixedly connected to the inner surface of the mounting groove 33. The elastic force of the second spring 37 pushes the connecting plate 36 to move, thereby automatically inserting the long rod 34 into the inner surface of the circular hole 32. A positioning plate 38 is fixedly connected to the surface of the hollow plate 205, and the positioning plate 38 is slidably connected to the surface of the protective cover 31. When the user assembles the protective cover 31, the surface of the protective cover 31 abuts against the positioning plate 38, guiding the protective cover 31 into the inner surface of the hollow plate 205.

[0025] Working principle: When the user needs to adjust the angle of the car door using the adjustment device 2, the car door is first pulled to move the hollow plate 205. The limiting plate 203 slides on the inner surface of the hollow plate 205. With the support of the clamping plate 201 and the fixing plate 1, the limiting plate 203 begins to rotate on the arc surface of the round rod 202. With the support of the drive plate 210 and the L-shaped frame 207, the setting rod 206 begins to slide on the surface of the side plate 209 and the L-shaped frame 207. The two setting rods 206 begin to slide on the insertion rod 211. The first spring 208 is compressed. The setting rods 206 begin to slide one by one on the arc surface of the groove 204. After adjusting to the appropriate groove 204, the first spring 208 rebounds and abuts the setting rod 206 against the groove 204. When it is necessary to position the limiting plate 203, the positioning rod 213 is inserted into the inner surface of the clamping plate 201 and the limiting plate 203 to form damping on the car door and slow down the movement of the car door.

[0026] When the user needs to use the protective device 3 to protect the parts on one side of the hollow plate 205, first pull the handle 35 to drive the long rod 34 to slide on the inner surface of the setting groove 33. The connecting plate 36 on the arc surface of the long rod 34 is compressed by the second spring 37 until the long rod 34 is fully inside the setting groove 33. The sliding protective cover 31 slides on the surface of the limiting plate 203 and the surface of the protective cover 31 is pressed against the surface of the positioning plate 38. Push the protective cover 31 again until the protective cover 31 reaches the lowest point. Release the handle 35, the second spring 37 rebounds, and the second spring 37 pushes the connecting plate 36. The connecting plate 36 drives the long rod 34 to slide on the inner surface of the setting groove 33 until the long rod 34 enters the inner surface of the round hole 32 and limits the protective cover 31.
