Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to a novel magnetic stopper for an automobile tailgate. Background Art

[0002] At present, traditional automobile tailgate limiters mostly use mechanical limiters, which have the problems of complex assembly, difficult parts replacement, high cost and insufficient buffering performance, resulting in short product life, high noise and affecting user experience. An existing automobile tailgate limiter assembly (publication number: CN107816268) has the following disadvantages and needs further improvement.

[0003] Traditional equipment lacks magnetic adjustability. Since the mechanical limiter uses fixed metal parts and mechanical connections, its limit function depends on physical contact and fixed position, and cannot be adjusted according to actual needs. This fixed limit method is very inconvenient during assembly and replacement of accessories, and cannot flexibly adapt to changes in different models or usage requirements. Once installed, if the limit position needs to be adjusted or accessories need to be replaced, the entire device needs to be disassembled, which is time-consuming and labor-intensive, increasing the complexity and cost of production and maintenance. In addition, the magnetic force cannot be adjusted, and the limit effect of the traditional mechanical limiter is relatively rigid, which is prone to component wear due to long-term use, thereby affecting the limit effect and service life. Therefore, a magnetic limiter with magnetic adjustability design is urgently needed. Traditional equipment uses rigid metal parts, which will directly bear the impact force when the tailgate is closed, and lacks an effective buffer design. This design causes the tailgate to easily generate a large impact force and noise when closing, affecting the user experience, and also causing damage to the body and the limiter itself. In the case of frequent opening and closing of the tailgate, the impact force will aggravate the wear of the components, shorten the service life of the limiter, and increase the frequency of repair and replacement. The rigid design of traditional mechanical limiters cannot effectively absorb and alleviate the impact force when closing, which easily leads to violent collision noises between metal parts, which not only causes noise interference to users, but also affects the riding comfort in the car. The lack of buffer structure design makes traditional mechanical limiters incapable of dealing with impact and noise problems, and it is difficult to meet users' needs for a quiet and smooth use experience. Therefore, a magnetic limiter with a buffer structure design is urgently needed. Utility Model Content

[0004] The main purpose of the utility model is to provide a novel automobile tailgate magnetic limiter, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: there is a new type of automobile tailgate magnetic limiter, an active magnetic limiter is installed above the main body, a driven magnetic limiter is installed below the main body, a magnetic contact point is installed on the top of the active magnetic limiter, a magnet anti-detachment cover is installed on the top of the active magnetic limiter, a sheath is installed on the outside of the active magnetic limiter, a limiter body is installed inside the active magnetic limiter, a magnet is installed inside the active magnetic limiter, a magnetic auxiliary block is installed on the top of the driven magnetic limiter, a protective rubber sleeve is installed outside the driven magnetic limiter, a bolt is installed at the bottom of the driven magnetic limiter, and a connecting seat is installed inside the driven magnetic limiter.

[0006] Preferably, the exterior of the main body adopts a rounded corner design.

[0007] Preferably, there are four magnetic contact points formed at the top of the active magnetic limiter.

[0008] Compared with the prior art, the utility model has the following beneficial effects:

[0009] In the assembly production stage of the utility model, the magnetic force adjustability enables the factory to flexibly adjust the magnetic force strength according to the specific needs of different models or different customers, without the need to produce different limiters for each demand. The production process is simplified and the production cost is reduced. In addition, in actual use, if it is necessary to replace accessories or adjust the limit position, the user only needs to simply adjust the magnetic force without disassembling the entire device. It saves time and energy, and also reduces the damage and wear of the equipment that may be caused by frequent disassembly and assembly. In long-term use, the magnetic force adjustability also helps to maintain the functionality and reliability of the limiter, because the user can adjust the magnetic force according to the actual use situation to avoid the failure of the limiter or damage to the components due to insufficient or excessive magnetic force. The utility model can effectively absorb and disperse these impact forces, reducing the noise and vibration when the door is closed. It improves the comfort of the user during use, and avoids unnecessary noise interference when used in a quiet environment or at night. The buffer structure also effectively protects the vehicle body and the limiter body, avoiding damage and wear caused by frequent impacts, thereby extending the service life of the equipment and reducing the frequency of repair and replacement. For vehicles that frequently use the tailgate, such as logistics vehicles and commercial vehicles, it greatly reduces equipment maintenance costs and vehicle downtime.

[0018] Example

[0019] See also Figure 1-4 , the utility model provides a technical solution:

[0020] A new type of automobile tailgate magnetic limiter, wherein an active magnetic limiter 2 is installed above the main body 1, a driven magnetic limiter 3 is installed below the main body 1, a magnetic contact point 4 is installed on the top of the active magnetic limiter 2, a magnet anti-drop cover 5 is installed on the top of the active magnetic limiter 2, a sheath 6 is installed on the outside of the active magnetic limiter 2, a limiter body 7 is installed inside the active magnetic limiter 2, a magnet 8 is installed inside the active magnetic limiter 2, a magnetic auxiliary block 9 is installed on the top of the driven magnetic limiter 3, a protective rubber sleeve 10 is installed outside the driven magnetic limiter 3, a bolt 11 is installed at the bottom of the driven magnetic limiter 3, and a connecting seat 12 is installed inside the driven magnetic limiter 3.

[0021] The following is a specific implementation of the utility model components:

[0022] 1. Subject:

[0023] The main body is the basic structure of the entire magnetic stopper, providing a mounting and support platform for other components. It is designed to have sufficient strength and rigidity to withstand the impact and vibration when the tailgate is closed. At the same time, the main body has good corrosion resistance to cope with long-term use under various environmental conditions. The structural design of the main body should be as simple as possible to facilitate large-scale production and assembly.

[0024] 2. Active magnetic limiter:

[0025] The active magnetic stopper is a magnetic device installed on the side of the vehicle body. It is mainly responsible for providing magnetic force to ensure that the tailgate can be firmly adsorbed and limited when closing. Through interaction with the driven magnetic stopper, the automatic alignment and limit function of the tailgate is realized. The magnetic strength of the active magnetic stopper can be adjusted to suit tailgates of different weights and types.

[0026] 3. Driven magnetic limiter:

[0027] The driven magnetic stopper is installed on one side of the tailgate, opposite to the active magnetic stopper. When the tailgate is closed, the driven magnetic stopper is attracted by the active magnetic stopper, thus achieving automatic closing and limiting of the tailgate. This component is made of high-strength magnetic material to ensure reliability and durability in long-term use.

[0028] 4.Magnetic contact point:

[0029] The magnetic contact point is the part of the magnetic stopper that directly contacts the tailgate. It is designed to achieve good magnetic force transmission and stable adsorption when the tailgate is closed. The surface of the magnetic contact point is treated to increase friction and wear resistance, thereby increasing service life.

[0030] 5.Magnet anti-drop cover:

[0031] The magnet anti-drop cover is used to protect the magnet from the external environment and prevent the magnet from falling off during use. It must be designed to fit the magnet tightly and have good sealing performance. The magnet anti-drop cover is made of corrosion-resistant materials to ensure long-term use under various environmental conditions.

[0032] 6. Sheath:

[0033] The cover is used to cover and protect the key parts of the limiter to prevent them from being damaged during use. The cover is made of flexible material with good wear resistance and impact resistance. It can effectively absorb and alleviate the impact force when the tailgate is closed, reducing the wear and noise of the parts.

[0034] 7. Limiter body:

[0035] The limiter body is the core of the entire magnetic limiter, providing a mounting platform and supporting structure for other components. Its design needs to take into account strength, rigidity and lightness to meet the needs of different models.

[0036] 8. Magnets:

[0037] The magnet is the key component of the magnetic stopper to achieve magnetic adsorption and limit functions. The magnetic strength and the choice of magnetic materials directly affect the working effect of the device. The magnet is precisely processed and debugged to ensure that it provides stable and reliable magnetic force during use.

[0038] 9. Magnetic auxiliary block:

[0039] The magnetic auxiliary block is used to enhance and adjust the magnetic effect of the magnetic stopper. It is designed to work closely with the magnet and magnetic contact points to achieve the best magnetic transmission and adsorption effect. The material selection and structural design of the magnetic auxiliary block play an important role in optimizing the performance of the entire device.

[0040] 10. Protective rubber sleeve:

[0041] The protective rubber sleeve is used to cover and protect the key components of the limiter to prevent them from being affected by the external environment during use. The protective rubber sleeve is made of flexible material and has good wear resistance and impact resistance. It can effectively extend the service life of the device and reduce the frequency of maintenance and replacement.

[0042] 11. Bolts:

[0043] Bolts are used to securely connect the stopper components to ensure that they can work stably and reliably during use. Bolts are designed to have sufficient strength and corrosion resistance to adapt to different use environments and conditions.

[0044] 12.Connection seat:

[0045] The connector is the basic structure for installing and fixing the magnetic stopper. It works closely with the vehicle body and tailgate to ensure that the stopper can work stably and reliably during use. The design of the connector needs to take into account strength, rigidity and lightness to meet the needs of different models.

[0046] The following is the specific technical logic implementation method of the innovative point of this utility model:

[0047] 1. Specific technical logic implementation of magnetic force adjustability:

[0048] The adjustability of magnetic force is mainly achieved by adjusting the arrangement or number of magnets. In the magnetic limiter, the magnet can be designed with an adjustable position or a replaceable modular magnet assembly. By designing multiple magnet mounting holes on the limiter body, users can install or adjust magnets in different holes as needed, thereby changing the position and strength of the magnetic force. In addition, magnet modules with different magnetic strengths can also be used, and users can select and replace magnet modules according to actual needs to adjust the overall magnetic force. In order to ensure the convenience and reliability of the adjustment process, the magnet mounting holes and modular design should have good fixing and positioning functions to prevent the magnet from shifting or loosening during use. This design not only makes the magnetic force adjustment process simple and easy, but also can adapt to the personalized needs of different models and users, and improves the applicability and flexibility of the limiter.

[0049] 2. Specific technical logic implementation of the buffer structure:

[0050] The buffer structure is mainly achieved by adding materials or components with shock absorption and buffering functions to the limiter. Buffer pads and buffer springs can be installed at the contact point between the limiter body and the door. These buffer materials are made of highly elastic and wear-resistant rubber or polymer materials, which can effectively absorb and disperse the impact force when the door is closed, reducing vibration and noise. In addition, buffer springs or dampers can be designed at the key connection parts of the limiter. These components can provide additional buffering and shock absorption effects when the door is closed, further reducing impact force and noise. In order to ensure the durability and reliability of the buffering effect, the buffering materials and components should have good weather resistance and aging resistance, and can be used for a long time under various environmental conditions without performance degradation. Through these designs, the buffer structure can significantly improve the comfort and durability of the limiter and reduce the maintenance and replacement frequency of the equipment.

[0051] The following is the workflow of this utility model:

[0052] 1. Installation phase:

[0053] a) First, fix the limiter body to the corresponding positions of the vehicle body and tailgate to ensure that it is firm and stable.

[0054] b) The active magnetic limiter and the driven magnetic limiter are installed at the predetermined positions of the vehicle body and the tailgate respectively, and preliminary alignment is achieved through the magnetic contact points.

[0055] c) Ensure that the magnet is installed in the magnet anti-drop cover and the magnetic auxiliary block, and is covered with a sheath and a protective rubber sleeve to increase its protection and durability.

[0056] d) Use bolts to firmly connect each component to the limiter body and the connecting seat to complete the overall installation.

[0057] 2. Adjustment stage:

[0058] a) According to the weight and usage requirements of the vehicle tailgate, adjust the magnet installation hole position or replace the modular magnet assembly to adjust the strength and position of the magnetic force.

[0059] b) Check and adjust the buffer structure to ensure that the buffer pad, buffer spring or damper is in the best working condition and can effectively absorb and disperse the impact force.

[0060] 3. Use phase:

[0061] a) When the tailgate is closed, the active magnetic stopper and the driven magnetic stopper are automatically aligned and adsorbed through the magnetic contact points to ensure that the tailgate closes smoothly.

[0062] b) The buffer structure absorbs and disperses the impact force during the door closing process, reduces vibration and noise, and protects the vehicle body and the limiter body.

[0063] c) The user can adjust the magnetic strength and buffer effect at any time according to actual usage to ensure that the limiter maintains the best working condition for a long time.

[0064] 4. Maintenance phase:

[0065] a) Regularly check the condition of the various components of the limiter, especially the wear of the magnet and buffer structure.

[0066] b) If worn or malfunctioning parts are found, the user can quickly restore the normal function of the limiter by simply adjusting or replacing modular components, avoiding disassembly of the entire device.

[0067] c) Keep the limiter clean to prevent dust and dirt from affecting its working performance and life.
