Description

Technical Field

[0001] This utility model relates to the field of automotive gear levers, specifically a dustproof and waterproof structure for automotive gear levers. Background Technology

[0002] The gear lever in a car is the control lever for the vehicle's transmission, used to switch gear combinations, thereby changing the vehicle's speed and power output. In traditional manual transmission vehicles, the gear lever is usually located on the right side of the driver's seat, and shifting gears is done by moving it forward, backward, left, or right, requiring the use of a clutch.

[0003] For example, authorization announcement number CN218454950U discloses a gear shift lever for automobiles, including a gear shift seat. The gear shift seat has an operating groove in its center, and a gear shift lever is movably mounted inside the operating groove. An extension seat is fixedly mounted on the left side of the bottom of the gear shift seat, and a mounting seat is fixedly mounted on the bottom of the inner side of the extension seat. A limit rod is fixedly mounted on the front of the mounting seat. This invention uses a magnetic ring to magnetically connect with the limit rod, preventing the gear shift lever from being moved forward (i.e., from "D" to other gears). To switch gears, the handle can be pulled upwards to apply an upward force to the limit block and compress the limit spring, causing the limit block to displace relative to the limit groove, releasing the lock between the magnetic ring and the limit rod. The gear shift lever can then be moved forward to complete the gear shift. This unintuitive and accidental design avoids accidental gear shifting, effectively improving driving safety and extending the service life of the transmission.

[0004] However, the above-mentioned technologies use an open structure between the gear shift seat and the gear lever, which makes it easy for dust in the air to enter the interior of the gear shift seat, and it is not waterproof. Therefore, the market urgently needs to develop a dustproof and waterproof structure for car gear levers to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof and waterproof structure for automobile gear levers, so as to solve the problem mentioned in the background art that the existing technology uses an open structure between the gear lever and the gear seat, which makes it easy for dust in the air to enter the interior of the gear seat, and at the same time, it does not have waterproof capabilities.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 This utility model provides an embodiment of a dustproof and waterproof structure for a car gear shift lever, including a gear shift lever 1. A plug-in post 102 is fixedly connected to the lower middle part of the gear shift lever 1. A leather protective cover 2 is connected to the lower end of the gear shift lever 1. A connecting post 3 is fixedly connected to the upper middle part of the interior of the leather protective cover 2. A partition plate 301 is fixedly provided in the middle part of the interior of the connecting post 3. A first slot 302 is provided between the upper end of the partition plate 301 and the upper end face of the connecting post 3. The upper end of the connecting post 3 is flush with the upper end face of the leather protective cover 2. Rectangular limiting strips 303 are fixedly connected to both sides of the interior of the first slot 302. Rectangular limiting grooves 104 are provided in the middle of the end faces of both sides of the plug-in post 102. The plug-in post 102 is inserted into the interior of the first slot 302 and the two rectangular limiting strips 303 slide into the two rectangular limiting grooves 104 respectively. The rectangular limiting strips 303 and the rectangular limiting grooves 104 cooperate to position the gear shift lever 1 when it is connected to the leather protective cover 2, preventing the gear shift lever 1 from rotating on the upper end of the leather protective cover 2.

[0025] Please see Figure 2 and Figure 3A second slot 304 is provided between the lower end of the partition plate 301 and the lower end face of the connecting post 3. A stop bar 4 is connected to the lower end of the connecting post 3. The upper end of the stop bar 4 is inserted into the second slot 304. A second threaded hole 401 is provided in the middle of the upper end face of the stop bar 4. A first threaded hole 101 is provided in the middle of the upper end face of the gear lever 1. A through hole 103 is provided at the lower end of the first threaded hole 101 and in the middle of the gear lever 1 and the insertion post 102. A bolt 5 is used to connect the gear lever 1 and the stop bar 4, passing through the first threaded hole 101, the through hole 103 and the middle of the partition plate 301. The gear lever 1 is inserted into the second threaded hole 401 and threadedly connected and fixed to the gear shift lever 4, thus fixing the gear lever 1 and the gear shift lever 4. A sealing ring 201 is provided between the lower end of the gear lever 1 and the upper end of the leather protective cover 2. When the gear lever 1 and the gear shift lever 4 are fixed together by bolts 5, the upper end of the gear shift lever 4 pushes up the partition plate 301, which in turn pushes up the connecting column 3 and the upper end of the leather protective cover 2, so that the leather protective cover 2 and the lower end of the gear lever 1 clamp the sealing ring 201, and fix the lower end of the leather protective cover 2 to the opening of the gear shift seat to achieve waterproof sealing.

[0026] Please see Figure 2 and Figure 5 A circular cover 6 is inserted into the upper end of the first threaded hole 101. An external threaded tube 601 is fixedly connected to the lower end of the circular cover 6. A screwdriver groove 602 is provided in the middle of the upper surface of the circular cover 6. The circular cover 6 and the gear lever 1 are fixedly connected by the external threaded tube 601 inserted into the first threaded hole 101. The circular cover 6 seals the first threaded hole 101. When disassembly is required, the circular cover 6 is moved by inserting a screwdriver head into the screwdriver groove 602, so that the circular cover 6 is disengaged from the first threaded hole 101. The bolt 5 can then be removed to separate the gear lever 1 from the gear shift lever 4.

[0027] Working principle: In use, first insert the upper end of the shift lever 4 into the second slot 304 of the connecting post 3, and simultaneously insert the insertion post 102 at the lower end of the shift lever 1 into the first slot 302, so that the rectangular limiting strip 303 and the rectangular limiting groove 104 engage to achieve radial positioning. Next, pass the bolt 5 through the first threaded hole 101, the through hole 103, and the through hole in the center of the partition plate 301 of the shift lever 1 in sequence, and finally screw it into the second threaded hole 401 of the shift lever 4 to tighten it. As the bolt 5 is tightened, the shift lever 4 will push the partition plate 301 upward, thereby driving the connecting post 3 and the leather protective cover 2 to move upward as a whole, so that the sealing ring 201 between the upper end of the leather protective cover 2 and the lower end of the shift lever 1 is pressed together to form a waterproof sealing layer. Finally, screw the circular cover 6 into the top of the first threaded hole 101 through the external threaded tube 601 to completely seal the installation hole. This structure, through its fully enclosed leather protective cover 2 and multiple sealing mechanisms, effectively prevents dust and moisture from entering the shifting mechanism. Simultaneously, the rectangular limiting structure ensures that the gear lever 1 will not rotate relative to it, and the concealed installation of the bolts 5 ensures both structural strength and a clean appearance. When disassembly and maintenance are required, simply unscrew the circular cover 6 with a screwdriver to expose the bolts 5 for disassembly.
