Description

Technical Field

[0001] This utility model relates to the technical field of automotive hinge limiters, and in particular to an integrated automotive hinge limiter. Background Technology

[0002] Automotive hinge limiters are mechanical devices installed at the door hinges, mainly used to control the door opening angle and maintain the stability of the door in a specific position. Their core functions include limiting the maximum door opening to prevent collisions, providing multiple hovering positions for easy passenger entry and exit, and achieving smooth door opening and closing through a damping structure. Common types include torsion bar type, cable type, and gear type. They must have high strength, wear resistance, and corrosion resistance to ensure long-term reliability.

[0003] Chinese patent CN211619793U discloses a height limiter for an integrated switch. This patent includes an upper cover structure, a working mechanism, and a sealing strip. The upper cover structure is installed inside the working mechanism, and a sealing strip is provided between the upper cover structure and the working mechanism. Galvanized screws and gear grooves are installed inside the base, with the upper end of the galvanized screws connected to fixing screw holes, making the height limiter easier to install and remove. This height limiter uses a wiring sleeve and a warning light installed on one outer wall of the base, and a height infrared sensor installed on the inner wall of the base. The height infrared sensor is electrically connected to the warning light, allowing the machine to measure and transmit signals of the height reached in a timely manner. If the height does not match the limit, a warning light will be activated to alert the operator, preventing machine malfunctions that could affect work efficiency or even endanger the operator's life due to untimely height limiting.

[0004] In existing technologies, automotive door limiters primarily use torsion bar dampers installed on both sides of the door panel to achieve a limiting effect. However, torsion bar dampers can only achieve limiting at specific locations, i.e., gear position limiting. This limiting method restricts the door to specific locations and cannot achieve stepless positioning, thus requiring improvement. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an integrated automotive hinge limiter.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated automotive hinge limiter includes a first mounting plate and further includes:

[0008] The damping limiting assembly includes a tripod mounted on the back of the first mounting plate, a sleeve fixed in the middle of the tripod, a damping inner liner fixed in the middle of the sleeve, a piston slidably mounted inside the damping inner liner, and a rubber strip connected to one side of the piston.

[0009] A further technical solution involves providing abrasive particles on the inner wall of the damping liner and using hard rubber material for the rubber strips.

[0010] A further technical solution involves providing screw holes and a first bolt around the perimeter of the first mounting plate.

[0011] A further technical solution involves a protective cover on one side of the first mounting plate, with a rubber strip slidably positioned inside the protective cover, and lubricating grease provided inside the protective cover.

[0012] Further technical solutions also include:

[0013] The auxiliary installation component includes a second mounting plate that is aligned and mounted on the car door panel, a second protective cover that is provided on one side of the second mounting plate, and a rubber strip that is inserted and installed inside the second protective cover.

[0014] A further technical solution involves setting a limiting ball at the end of the rubber strip.

[0015] A further technical solution involves providing screw holes around the perimeter of the second mounting plate, with a second bolt installed inside the screw holes.

[0016] Compared with the prior art, this utility model provides an integrated automotive hinge limiter, which has the following advantages:

[0017] This invention utilizes a damping limiting component and an auxiliary installation component. The limiting part of this component is a rubber strip structure that is movably installed inside the protective cover and the second protective cover. The rubber strip pulls the piston to move inside the damping liner, thereby achieving the effect of damped opening and closing of the door panel. Moreover, regardless of where the door is parked, the piston can remain at any position under the action of the damping liner, thus allowing the door to remain at any position as well, increasing the stopping effect of the limiter.

[0024] Example 1: Refer to Figure 1 - Figure 4 An integrated automotive hinge limiter includes a first mounting plate 1, which is mounted on one side of the vehicle body, and further includes:

[0025] The damping limiting assembly 2 includes a tripod 4 mounted on the back of the first mounting plate 1. The tripod 4 is used to fix a sleeve 5 in the middle. The sleeve 5 is fixed in the middle of the tripod 4, and a damping inner liner 6 installed inside the sleeve 5 is used to achieve the damping movement of the piston 7. The damping inner liner 6 is fixed in the middle of the sleeve 5, and the piston 7 is slidably mounted inside the damping inner liner 6. A rubber strip 8 is connected to one side of the piston 7 and is used to output the damping movement of the piston 7 to the door panel.

[0026] The integrated automotive hinge limiter described above has a damping inner liner 6 with abrasive particles on its inner wall, which form the basic structure for the damping movement of the piston 7. The rubber strip 8 is made of hard rubber material to prevent easy damage during pulling.

[0027] The integrated automotive hinge limiter has screw holes and a first bolt 10 around the periphery of the first mounting plate 1, and the first bolt 10 fixes the first mounting plate 1 to the vehicle frame.

[0028] The integrated automotive hinge limiter described above includes a protective cover 9 on one side of the first mounting plate 1. The protective cover 9 serves as a limiting and protective component for the rubber strip 8. The rubber strip 8 is slidably disposed inside the protective cover 9, and the interior of the protective cover 9 is provided with grease. The grease enhances the lubrication and protection effect of the rubber strip 8 within the protective cover 9.

[0029] The integrated automotive hinge limiter further includes:

[0030] The auxiliary installation component 3 includes a second mounting plate 12 aligned and mounted on the vehicle door panel. The second mounting plate 12 is an alignment and mounting component of the first mounting plate 1. A second protective cover 13 is provided on one side of the second mounting plate 12, and the function of the second protective cover 13 is to protect the cover 9. The rubber strip 8 is inserted and installed inside the second protective cover 13.

[0031] The integrated automotive hinge limiter has a limit ball 11 at the end of the rubber strip 8. The function of the limit ball 11 is to prevent the rubber strip 8 from detaching from the second mounting plate 12 during the pulling process.

[0032] The integrated automotive hinge limiter described above includes a second mounting plate 12 with screw holes around its periphery. A second bolt 15 installed inside the screw holes is used to fix the second mounting plate 12 to the car door. The second bolt 15 is installed inside the screw holes.

[0033] Working principle:

[0034] In the actual design process of this utility model, to avoid the following defects existing in the prior art: "In the prior art, automobile limiters are mainly installed on both sides of the door panel using a torsion bar limiting method to achieve the limiting effect. However, the torsion bar damper can only achieve limiting at specific locations, that is, gear limiting. This limiting method means that the door can only be positioned at specific locations and cannot achieve stepless positioning, so it needs to be improved." Therefore, a damping limiting component 2 and an auxiliary installation component 3 are specifically proposed.

[0035] Damping limit component 2:

[0036] This component mounts a sliding piston 7 to the end of a rubber strip 8. During the opening and closing of the car door, the rubber strip 8 pulls the piston 7 to reciprocate within the damping liner 6. The abrasive particles on the inner wall of the damping liner 6 dampen the piston 7's movement. The outer sleeve 5 is a component of the concealed damping liner 6, and the surrounding triangular bracket 4 secures the inner sleeve 5. The opening and closing of the car door causes the piston 7 to slide within the damping liner 6. The damping effect of the damping liner 6 prevents the car door from wobbling when open. Furthermore, the protective cover 9 and the second protective cover 13 are where the rubber strip 8 is slidably mounted, primarily serving to protect and lubricate it.

[0037] Auxiliary installation component 3:

[0038] This component is a part of the damping limiting assembly 2 that is installed in alignment to achieve the complete pulling effect of the rubber strip 8. Its structure includes a second mounting plate 12, a second protective cover 13, and a second bolt 15; the rubber strip 8 passes through the inside of the second protective cover 13 and a limiting ball 11 is installed at the bottom to prevent the rubber strip 8 from falling out of the device during the pulling process.
