Description

Technical Field

[0001] This utility model belongs to the technical field of door limiters, specifically a door limiter disassembly and assembly structure. Background Technology

[0002] The main function of a door limiter is to restrict the degree to which a car door can be opened. On the one hand, it can limit the maximum opening angle of the door to prevent it from opening too wide. On the other hand, it can keep the door open when needed, such as when the car is parked on a slope or when it is windy, so that the door will not close automatically.

[0003] A search revealed that patent CN222615068U discloses a car door limiter, including a main limiter arm. A limiter box is fitted onto one end of the main limiter arm. The limiter box has mounting grooves at both ends, with a compression spring fixedly installed inside each groove. A slider is fixed to one end of the compression spring, and the slider is pressed against the main limiter arm by the spring's tension. A limiter groove matching the slider is formed at the other end of the main limiter arm. A fixing groove inside the limiter box is formed on one side of the mounting groove, with a locking solenoid valve fixed inside one of the fixing grooves. A locking groove corresponding to the telescopic valve needle of the locking solenoid valve is formed at one end of the main limiter arm. This car door limiter has an electromagnetic locking function and is suitable for vehicle-controlled door anti-collision systems. It provides a solution for abnormally opened car doors, optimizes anti-collision control, and effectively solves the problems of vehicle damage and personal safety caused by abnormally opened car doors.

[0004] Based on the existing technology described above, when the door limiter's stop block or limit box is damaged due to long-term use, it is usually necessary to remove the limiter from the inside of the door before the components can be disassembled and replaced. This makes replacing the limiter quite troublesome, and since most components are fixed as a single piece, maintenance efficiency is reduced. Therefore, we provide a door limiter disassembly and assembly structure to solve these problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, through the coordinated arrangement of an mounting plate, two limit boxes, connecting parts, and a positioning mechanism, allows for quick installation by first fitting the mounting plate onto the surface of the limit arm, and then sliding the two limit boxes relative to each other on the left side of the mounting plate. If a limit box is damaged and needs replacement, only the corresponding limit box needs to be disassembled individually; the entire assembly is not required. During installation, the limit box is quickly fixed by sliding the side plate into the limit plate until the L-shaped insert is inserted into the positioning hole. When the limit box needs to be disassembled, simply pull the two corresponding L-shaped inserts outwards to release the L-shaped inserts from the side plate, and the limit box is pushed out by the elastic force of the second compression spring.

When the stop block is damaged and needs to be replaced, simply pull the two sliding plates outward to easily remove it from the left end of the limiting arm. Then, simply insert the new stop block into the left end of the limiting arm to complete the assembly. The operation process requires no other auxiliary tools, which is more conducive to personnel's subsequent maintenance operations. Attached Figure Description

[0024] 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.

[0025] Example 1, such as Figures 1-8 As shown, this embodiment proposes a door limiter disassembly and assembly structure, including a limit arm 1, a mounting plate 3 sleeved on the surface of the limit arm 1, a stop block 2 sleeved on the left end of the limit arm 1, and two opposing positioning grooves 11 formed on the left end of the limit arm 1. Two opposing snap-fit ​​mechanisms are provided inside the stop block 2, and the stop block 2 snaps into the corresponding positioning grooves 11 through the snap-fit ​​mechanisms. With the above structure, the stop block 2 can be easily and quickly disassembled and assembled on the limit arm 1 using the snap-fit ​​mechanisms, which facilitates subsequent replacement of components and simplifies the operation. Two opposing limit boxes 5 are detachably connected to the left side of the mounting plate 3; the limit boxes 5 are existing mature technology. The device contains an arc-shaped protrusion and an elastic element. The specific principle will not be detailed here. Connectors 4 are fixed to both ends of the right side of the mounting plate 3. The left side of the mounting plate 3 is provided with a positioning mechanism for fixing two limit boxes 5. With the above structure, the two limit boxes 5 can be assembled and fixed on the left side of the mounting plate 3. When one of the limit boxes 5 is damaged and needs to be disassembled and replaced, it can be removed normally by simply releasing the corresponding positioning mechanism from fixing the limit box 5. The operation is more flexible and convenient, without the need to disassemble it as a whole from the limit arm 1. The mechanics, parts and equipment in this device all adopt conventional models in the existing technology, which will not be detailed here.

[0026] Example 2: The solution in Example 1 will be further described below with reference to its specific working method. See the description below for details:

[0027] like Figure 1 , Figure 2 , Figure 4 and Figure 8As shown, the locking mechanism includes a mounting cavity 16, which is formed within the stop block 2. A locking block 15 and a sliding plate 10 are slidably disposed within the mounting cavity 16. One end of the sliding plate 10 extends to the outside of the stop block 2. The locking block 15 and the sliding plate 10 are connected. One end of the locking block 15 protrudes to the outside of the stop block 2 and engages with the positioning groove 11. Several third compression springs 17 are fixedly connected to the locking block 15, and one end of each third compression spring 17 is connected to the inner wall of the mounting cavity 16. With this structure, the stop block 2 can be quickly and easily engaged with the limiting position. The left end of arm 1 is assembled and fixed by simply inserting the stop block 2 directly into the left end of the limiting arm 1. During this process, the locking block 15 will automatically extend into the mounting cavity 16 until it is in the positioning groove 11. Then, under the elastic force of the third compression spring 17, it will automatically insert into the positioning groove 11, thus preventing the stop block 2 from detaching from the left end of the limiting arm 1. Only by having personnel pull the two sliding plates 10 to pull the two locking blocks 15 out of the two positioning grooves 11 at the same time can the stop block 2 be removed normally. The operation is more convenient and facilitates the replacement of subsequent parts.

[0028] like Figure 2 and Figure 8 As shown, a slot 12 is provided at the left end of the limiting arm 1. A first pressing plate 13 is slidably disposed in the slot 12. A first compression spring 14 is fixedly connected to the inner wall of the first pressing plate 13, and one end of the first compression spring 14 is connected to the inner wall of the slot 12. The surface of the first pressing plate 13 is in pressing contact with the inner wall of the stop block 2. With the above structure, when the stop block 2 is sleeved on the left end of the limiting arm 1, it will squeeze the first pressing plate 13 to move in the slot 12 and compress the first compression spring 14 until the stop block 2 is completely engaged at the left end of the limiting arm 1. Then, the elastic force of the first compression spring 14 ensures the secure engagement of the stop block 2 at the left end of the limiting arm 1 and prevents it from shifting arbitrarily.

[0029] like Figure 1 , Figures 5 to 7As shown, the positioning mechanism includes two limiting plates 6, which are fixedly connected to the left side of the mounting plate 3. Side plates 9 are fixedly connected to both sides of the two limiting boxes 5, and the side plates 9 slide within their respective limiting plates 6. Limiting mechanisms for restricting the displacement of the side plates 9 are provided at both ends of the two limiting plates 6. Two pressing mechanisms for ejecting the corresponding side plates 9 are provided within each of the two limiting plates 6. With this structure, the limiting boxes 5 can be quickly installed and removed from the mounting plate 3, facilitating subsequent disassembly and replacement. Furthermore, if one of the two limiting boxes 5 is damaged and needs replacement, [further details are needed]. It can be removed and replaced individually without dismantling the whole unit. In specific operation, simply slide the limiting box 5 along the left side of the mounting plate 3 between the two limiting plates 6, so that the two side plates 9 slide into the two limiting plates 6 respectively. Finally, the limiting mechanism limits the side plates 9 to prevent the limiting box 5 from sliding at will. When it is necessary to remove the limiting box 5 from the mounting plate 3, simply release the limiting mechanism from the side plates 9 and use the squeezing mechanism to lift the side plates 9, thereby quickly removing the limiting box 5 from the mounting plate 3 without the need for other auxiliary tools, which is more conducive to the later maintenance operations of personnel.

[0030] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the limiting mechanism includes an L-shaped insert 7 and a positioning hole 21. The L-shaped insert 7 is disposed through the surface of the limiting plate 6, and the positioning hole 21 is opened on the surface of the side plate 9. One end of the L-shaped insert 7 is engaged with the side plate 9. A guide rod 8 is disposed through the surface of the L-shaped insert 7, and one end of the guide rod 8 is fixed to the surface of the limiting plate 6. A spring 18 is sleeved on the surface of the guide rod 8, and both ends of the spring 18 are fixed to the surface of the L-shaped insert 7 and the surface of the limiting plate 6, respectively. With the above structure, when the side plate 9 is inserted into the limiting plate 6, it will move one end of the L-shaped insert 7 outward until the positioning hole 21 is aligned with one end of the L-shaped insert 7. Then, the elastic force of the spring 18 will pull one end of the L-shaped insert 7 into the positioning hole 21, thereby limiting the displacement of the side plate 9. When it is necessary to release the restriction on the side plate 9, simply pull the L-shaped insert 7 outward.

[0031] like Figure 5 and Figure 6As shown, the compression mechanism includes a second compression spring 19, which is fixedly connected to the inner wall of the limiting plate 6. One end of the second compression spring 19 is fixedly connected to a second compression plate 20, and the second compression plate 20 is slidably disposed within the limiting plate 6. The second compression plate 20 is in compression contact with one end of the side plate 9. With the above structure, when the side plate 9 is slidably inserted into the limiting plate 6, one end of the side plate 9 will first compress the second compression plate 20 to move, causing the second compression spring 19 to be in a compressed state. After the limiting box 5 is fixed, the second compression plate 20 will be used to compress the side plate 9 under the elastic force of the second compression spring 19, thereby ensuring the stability of the side plate 9 within the limiting plate 6 and ensuring the stability of the limiting box 5 during use.

[0032] The working principle and usage process of this utility model are as follows: When assembling the limiter, firstly, the mounting plate 3 is placed on the surface of the limit arm 1. Then, the two limit boxes 5 are slid relative to each other on the left side of the mounting plate 3, and are slidably inserted into the limit plate 6 through the side plate 9 until the L-shaped insert 7 is inserted into the positioning hole 21, which can quickly fix the limit box 5. After being fixed, the limit box 5 will press the second compression plate 20 through the side plate 9, so that the second compression spring 19 is in a compressed state to ensure the stability of the limit box 5. Then, the stop block 2 is directly placed on the left end of the limit arm 1. During this process, the locking block 15 will automatically extend into the mounting cavity 16 until it is in the positioning groove 11. Then, under the elastic force of the third compression spring 17, it will automatically insert into the positioning groove 11, which can prevent the stop block 2 from detaching from the left end of the limit arm 1. The personnel assemble the mounting plate 3 to the inside of the car door using the connector 4. The right end of the limiting arm 1 is connected to the car body by rivets. When the limiting box 5 is damaged and needs to be replaced during use, it is not necessary to remove it completely. Simply pull the two corresponding L-shaped rods 7 to move them outward, so that the L-shaped rods 7 release the restriction on the side plate 9. Under the elastic force of the second compression spring 19, the limiting box 5 is pushed out. Then, the personnel can directly remove the damaged limiting box 5 and install the new one. When the stop block 2 is damaged and needs to be replaced, simply pull the two sliding plates 10 to move them outward, and it can be easily removed from the left end of the limiting arm 1. Then, the new stop block 2 can be directly inserted into the left end of the limiting arm 1 to complete the assembly. The operation does not require any other auxiliary tools, which is more conducive to the personnel's later maintenance operations.
