For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Reference below Figure 1-Figure 4 An electric limit stop assembly 100 according to an embodiment of the present invention is described.

[0036] An electric limiter assembly 100 according to an embodiment of the utility model.

[0037] like Figure 1 As shown, the electric limiter assembly 100 includes an electric limiter body 1 and a support rod 20 .

[0038] The support rod 20 includes an input section (not shown) and an output section 22 . The input section is connected inside the electric limiter body 1 , and the output section 22 is located outside the electric limiter body 1 .

[0039] It is worth mentioning that the electric limiter body 1 has a transmission mechanism, the input section of the strut 20 is connected to the transmission mechanism in the electric limiter body 1, and the output section 22 of the strut 20 is connected to the vehicle door. The strut 20 obtains power to achieve axial movement, thereby driving the opening and closing of the vehicle door.

[0040] When the support rod 20 is in the extended state, most of it is located outside the electric limiter body 1. If the protection effect of the support rod 20 is not good, the part outside the electric limiter body 1 is easy to get into water or other impurities. When the support rod 20 is in the retracted state, water or other impurities are brought into the electric limiter body 1, affecting the use of the electric limiter body 1 and reducing its service life. In particular, in some schemes, the support rod 20 itself also needs transmission cooperation. For example, in some schemes, the transmission mechanism includes a nut, and the power part of the electric limiter assembly 100 is a motor, which is driven by the transmission mechanism to rotate. The support rod 20 is also a lead screw, which cooperates with the nut. When the motor drives the nut to rotate, it drives the lead screw to move axially, thereby realizing the telescopic movement of the support rod 20. The support rod 20 is provided with a transmission thread. When there is no protection, the transmission thread is easy to be stained and rusted. When there is no protection, it is easy to affect the surface quality of the transmission thread. When the transmission is coordinated, the transmission surface gap is not stable, which is easy to generate a lot of noise.

[0041] To solve the above problems, the electric limiter assembly 100 of the present application further includes a sealing sleeve 30. Figure 1-Figure 3As shown, the sealing sleeve 30 is sleeved on the outside of the support rod 20, and the sealing sleeve 30 includes a first end 31 and a second end 32. The first end 31 is connected to the electric limiter body 1, and the second end 32 is sealed and connected to the output section 22 of the support rod 20. The length of the sealing sleeve 30 is telescopically adjustable.

[0042] The sealing sleeve 30 isolates the portion of the support rod 20 located outside the electric limiter body 1 from the external environment, thereby protecting the exposed portion of the support rod 20 .

[0043] like Figure 1 As shown, the sealing sleeve 30 is connected to the electric limiter body 1 through the first end 31, and the second end 32 is connected to the output section 22 of the support rod 20, and the length of the sealing sleeve 30 is telescopically adjustable. When the support rod 20 moves axially, the sealing sleeve 30 will expand and contract accordingly, and always remain sleeved on the outer periphery of the support rod 20. In this way, the sealing sleeve 30 can provide physical protection for the leaking part of the support rod 20, enhance the waterproof and dustproof capabilities of the electric limiter assembly 100, and also play a role in isolating noise, which helps to achieve noise reduction. At the same time, the setting of the sealing sleeve 30 also helps to extend the service life of the electric limiter assembly 100. The protective effect of the sealing sleeve 30 reduces the direct damage to the internal structure of the electric limiter assembly 100 caused by external factors, and reduces the risk of wear and aging of the electric limiter assembly 100.

[0044] like Figure 2 As shown, the second end 32 of the sealing sleeve 30 is sealedly connected to the output section 22 of the support rod 20, so that the sealing sleeve 30 can maintain a tight sealing effect, thereby ensuring that the interior of the sealing sleeve 30 always maintains a dry and clean environment.

[0045] It is understandable that in actual use of the electric limiter assembly 100, the output section 22 of the support rod 20 is connected to the vehicle door, and the electric limiter body 1 is located inside the vehicle body. In rainy weather, the vehicle door is easily exposed to external water sources, so the support rod 20 between the electric limiter body 1 and the vehicle door is covered with a sealing sleeve 30 to block external sewage and prevent the sewage from contaminating the electric limiter body 1.

[0046] In some embodiments, both ends of the sealing sleeve 30 and the support rod 20 are sealed and connected, and the cavity between the sealing sleeve 30 and the support rod 20 constitutes a closed cavity, thereby improving the sealing and waterproof properties.

[0047] In other embodiments, Figure 2As shown, an air cavity 33 is formed between the sealing sleeve 30 and the support rod 20, and the air cavity 33 can be connected to the outside and is ventilated. It is known that when the door is opened, the support rod 20 will extend from the electric limiter body 1, causing the volume of the air cavity 33 between the sealing sleeve 30 and the support rod 20 to increase. As the volume of the air cavity 33 increases, the volume of the gas in the air cavity 33 also increases accordingly, and the pressure of the gas will decrease accordingly. The sealing sleeve 30 is deformed by the pressure difference between the inside and the outside.

[0048] Therefore, according to some embodiments of the present invention, the electric limiter assembly 100, such as Figure 3 As shown, the electric limiter body 1 is provided with a vent hole 12 communicating with the air cavity 33. Of course, the position of the vent hole 12 is not limited to the electric limiter body 1, and can also be set at a position of the sealing sleeve 30 that is not easily exposed to the sewage environment. By providing the vent hole 12, air can be allowed to flow freely in the air cavity 33, thereby balancing the air pressure inside and outside the air cavity 33. When the support rod 20 is extended or retracted, the vent hole 12 allows external air to enter or exit the air cavity 33 to maintain the pressure balance inside and outside the air cavity 33.

[0049] Such a configuration not only helps to reduce the deformation of the sealing sleeve 30, but also improves the stability and reliability of the electric limiter assembly 100. By balancing the air pressure through the air vent 12, the stress of the sealing sleeve 30 caused by the pressure difference can be reduced, and the deformation can be reduced, thereby extending its service life. At the same time, such a configuration also avoids the friction or stagnation between the sealing sleeve 30 and the support rod 20 caused by the pressure difference, ensuring the smooth movement of the support rod 20.

[0050] According to the electric limiter assembly 100 of some embodiments of the present invention, the electric limiter body 1 includes a housing 10 and a transmission mechanism.

[0051] A matching hole 11 is provided at one end of the housing 10. Figure 3 As shown, the matching hole 11 is the main position for installing the input section of the support rod 20, ensuring a tight fit between the support rod 20 and the electric limiter body 1.

[0052] like Figure 3 As shown, the housing 10 is further provided with an air hole 12, and the inner cavity of the housing 10 is connected with the air cavity 33. The air hole 12 allows the gas in the air cavity 33 to exchange with the external environment, thereby maintaining the air pressure balance inside and outside the air cavity 33. During the movement of the support rod 20, the gas in the air cavity 33 can flow smoothly, avoiding unnecessary pressure or resistance caused by gas retention.

[0053] The transmission mechanism is located in the housing 10. The transmission mechanism is an important part of the electric limiter body 1. The transmission mechanism is responsible for controlling the movement of the support rod 20, thereby realizing the opening or closing function of the door.

[0054] The input section of the support rod 20 is installed in the housing 10 through the matching hole 11 and connected to the transmission mechanism. This arrangement ensures that the transmission mechanism can effectively convert kinetic energy into the movement of the support rod 20.

[0055] like Figure 4 As shown, the first end 31 of the sealing sleeve 30 is sealed and connected to the matching hole 11. The sealing performance between the support rod 20 and the electric limiter body 1 is further enhanced. The sealing of the sealing sleeve 30 and the matching hole 11 ensures that even under harsh environmental conditions, moisture, impurities, etc. cannot enter the interior of the electric limiter body 1, thereby ensuring its normal operation and long service life.

[0056] In some embodiments, Figure 3 As shown, the electric limiter assembly 100 further includes a waterproof and breathable membrane 40 covering the breathable hole 12 , which can ensure the air pressure balance and effectively prevent moisture and impurities from entering the electric limiter assembly 100 .

[0057] Optionally, the waterproof breathable membrane 40 has a microporous structure. It can allow gas molecules to pass through, but prevent the penetration of moisture and solid particles. When the movement of the support rod 20 causes the volume of the air cavity 33 to change, the waterproof breathable membrane 40 can respond quickly, so that the gas inside and outside the air cavity 33 is exchanged, thereby maintaining the air pressure balance. This balancing effect ensures the stable operation of the electric limiter assembly 100 and avoids performance degradation or damage caused by pressure difference. Since the waterproof breathable membrane 40 is not an improvement of the present application, the waterproof breathable membrane 40 in the prior art can be used, which will not be described in detail here.

[0058] In some embodiments of the present application, Figure 2 As shown, the electric limiter assembly 100 also includes a first adhesive layer 5. The first adhesive layer 5 is sealed and connected between the second end 32 of the sealing sleeve 30 and the output section 22 of the support rod 20. It ensures a tight fit and seamless connection between the two, thereby effectively preventing external moisture, impurities, etc. from entering the interior of the electric limiter assembly 100 through the connection gap. In addition, the use of the first adhesive layer 5 also enhances the connection strength between the support rod 20 and the sealing sleeve 30. It allows the support rod 20 to maintain a close fit with the sealing sleeve 30 during movement, reducing noise and wear caused by friction or vibration. Improve the reliability of the electric limiter assembly 100.

[0059] According to the electric limit assembly of some embodiments of the present application, at least one convex ring 23 is provided on the outer circumferential surface of the support rod 20, and the convex ring 23 is located in the output section 22, and there is an interference fit between the convex ring 23 and the sealing sleeve 30. The convex ring 23 increases the connection length between the support rod 20 and the sealing sleeve 30, improves the tightness of the connection between the support rod 20 and the sealing sleeve 30, and the interference fit effectively reduces the passage of gas and moisture into the interior of the electric limiter assembly 100, further enhancing its sealing performance.

[0060] In some embodiments, the sealing sleeve 30 includes a first circular ring, a second circular ring, and a third circular ring arranged in sequence on the inner circumference of the second end 32. The diameter of the second circular ring is smaller than the diameters of the first circular ring and the third circular ring. This makes the interior of the second end 32 have a structure that is small in the middle and large on both sides. The convex ring 23 is clamped in the position of the second circular ring to enhance the connection effect between the second end 32 and the support rod 20 to prevent it from coming out.

[0061] In some embodiments of the present application, the first ring is located on the sealing sleeve 30 away from the first end 31, and the diameter of the first ring gradually decreases from the outside to the inside, which not only meets the requirement that the second end 32 avoids the support rod 20 and connects with the outside, but also reduces the gap between the output section 22 of the support rod 20.

[0062] Optionally, a first adhesive layer 5 is provided between the protruding ring 23 and the sealing sleeve 30 , which can not only improve the protection effect but also help to improve the connection strength.

[0063] like Figure 4 As shown, according to the electric limiter assembly 100 of some embodiments of the present application, a junction box 6 is formed on the electric limiter body 1, and the electric limiter assembly 100 also includes a wiring harness 7. The output end of the wiring harness 7 is used for external power connection and communication, the input end of the wiring harness 7 is located in the junction box 6 and connected to the inside of the electric limiter body 1 through the junction box 6, and the junction box 6 is filled with a second adhesive layer, and the second adhesive layer covers the wiring harness 7 in the junction box 6.

[0064] The circuit connection of the electric limiter assembly 100 is managed and protected by the junction box 6 .

[0065] By pouring the second adhesive layer into the junction box 6, the second adhesive layer completely covers the wiring harness 7 in the junction box 6, thereby effectively preventing moisture, gas and other pollutants from entering the inside of the junction box 6 through gaps or holes. It is ensured that the electrical connection in the junction box 6 is always kept dry and clean, and the sealing performance and protection ability of the junction box 6 are improved.

[0066] In addition, the second adhesive layer also has good insulation performance, which can prevent risks such as short circuit and leakage, thereby providing a safer and more reliable use environment for the car owner. The electric limiter assembly 100 has IP67 waterproof and dustproof functions, allowing it to withstand a certain degree of environmental factors such as rain, dust, etc. without being damaged.

[0067] Alternatively, if Figure 4 As shown, the junction box 6 has a box opening 61 for conveniently installing and removing the wiring harness 7 and other connecting components.

[0068] like Figure 4 As shown, the electric limiter assembly 100 further includes a glue storage cover plate 62 detachably connected to the box opening 61. The glue storage cover plate 62 is connected to the box opening 61 to form a closed chamber to protect the wiring harness 7 and other internal components in the junction box 6, thereby ensuring the stability and reliability of the internal electrical connection.

[0069] The glue storage cover plate 62 also has a certain buffering effect, which can absorb external impact and vibration, and further protect the wiring harness 7 in the junction box 6 from damage.

[0070] In some embodiments, the glue storage cover 62 is screwed to the box opening 61 .

[0071] Optionally, the sealing sleeve 30 is a bellows. The bellows has excellent elasticity and scalability, and can better adapt to the expansion and contraction changes of the support rod 20. At the same time, as a universal tubular structure, the bellows has a variety of sizes suitable for electric limiter assemblies 100 of different specifications. Unified procurement can also reduce production costs.

[0072] Of course, the present application is not limited thereto, and the sealing sleeve 30 may also be made of an ordinary plastic tube, rubber tube, etc.

[0073] In some embodiments, Figure 4 As shown, the electric limiter assembly 100 includes a motor 8. The motor 8 is connected to the support rod 20 through a transmission mechanism to transfer kinetic energy to the support rod 20.

[0074] Optionally, the support rod 20 is a screw rod, which has a simple structure and high transmission efficiency.

[0075] In some embodiments, the electric limiter assembly 100 includes a hinge structure 9. The output section 22 of the support rod 20 is connected to the vehicle door through the hinge structure 9. The hinge structure 9 can adopt a known solution in the prior art. The hinge structure 9 itself is not the core point of the present application solution, so it will not be repeated here.
