Description

Technical Field

[0001] This utility model relates to the field of driver's cab technology, specifically to a fully sealed off-road vehicle body driver's cab structure. Background Technology

[0002] Off-road vehicles, designed specifically for off-road scenarios, are renowned for their powerful terrain adaptability, making them particularly suitable for complex road conditions such as rugged mountains and muddy wilderness. Their core characteristics include a robust frame provided by a non-load-bearing body structure, powerful power distribution from a four-wheel drive system, a high-ground-clearance chassis combined with high-grip off-road tires for enhanced passability, and a high-mounted exhaust pipe ensuring wading performance, all of which together form the hardware foundation for coping with harsh environments.

[0003] However, in terms of door sealing design, existing technologies generally employ a scheme where sealing strips and body strips work together. Because off-road vehicles operate under extreme conditions such as bumpy rides, dust, and water wading, the sealing strips are prone to displacement or deformation under the combined effects of repeated vibration, sudden temperature changes, and mud and sand erosion, leading to gaps between the sealing surfaces. This sealing failure allows rainwater to seep in and sand and dust to enter the passenger compartment, affecting the vehicle's user experience and durability. Therefore, there is an urgent need to optimize and upgrade the existing sealing structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fully sealed off-road vehicle cab structure, solving the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A fully sealed off-road vehicle body cab structure includes an off-road vehicle body, on which a cab door is installed;

[0007] A silicone strip is fitted to the inner wall of the driver's cab door. The silicone strip is used to seal the gaps in the door after it is inflated. A cavity is opened inside the silicone strip.

[0008] An inflation mechanism is installed inside the driver's cab door. The inflation mechanism is used to inflate the cavity of the silicone strip, causing the silicone strip to expand.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the inflation mechanism includes a squeezing component, an air storage component, a resetting component, and an air supply component. The squeezing component is used to squeeze the gas in the air storage component to supply air after contacting the vehicle body. The air storage component is used to store and supply air. The resetting component is used to reset the squeezing component. The air supply component is used to supply air to the cavity of the silicone strip.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] By refining the inflation mechanism into a compression component, an air storage component, a reset component, and an air supply component, the compression component provides inflation power, the air storage component ensures gas reserves, the reset component ensures the reusability of the mechanism, and the air supply component delivers gas. These multiple components enhance the stability and reliability of the inflation process, thereby ensuring that the silicone strip can expand stably to achieve a seal. Even under the complex working conditions of bumpy off-road driving, it can maintain a good sealing state.

[0013] Furthermore, the gas storage assembly includes a gas storage pipe, which is installed inside the driver's cab door.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] As the core component of air storage, the air storage pipe needs to be installed in the empty space inside the cab door for use. The air storage pipe can store a certain amount of gas. When the extrusion component is working, it can supply air to the cavity of the silicone strip, so that the silicone strip can start to expand when the door is closed, improve the sealing reaction speed, and prevent external dust and mud from entering the cab.

[0016] Furthermore, the extrusion assembly includes an extrusion block, on which a silicone pad is fitted and mounted, and a connecting rod is mounted on the extrusion block via a screw. A piston is mounted on the end of the connecting rod opposite to the extrusion block, and the piston is slidably sleeved inside the gas storage pipe.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] When the extrusion block contacts the car body, the silicone pad on its surface cushions the impact through its elastic deformation. This not only reduces hard wear between the extrusion block and the car body, extending their service life, but also reduces collision noise when the door closes, improving the driving experience. The extrusion block is connected to a connecting rod via a screw. The extension length of the extrusion block can be adjusted by rotating the screw, thereby adjusting the extrusion force according to the actual gap between the door and the car body, ensuring that the piston can generate appropriate pressure on the gas in the gas reservoir. The piston fits tightly against the inner wall of the gas reservoir, and when sliding, it can efficiently extrude the gas in the gas reservoir, stably converting the mechanical energy of closing the door into gas pressure, providing sufficient and stable power for inflating the silicone strip.

[0019] Furthermore, the reset assembly includes a second guide rod and a reset spring. Both the second guide rod and the reset spring are installed inside the gas storage pipe. A first guide rod is slidably sleeved inside the second guide rod. Both the first guide rod and the reset spring are connected to the piston. The reset spring is sleeved on the second guide rod and the first guide rod.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] When the car door is opened and the compression assembly is no longer under pressure, the return spring, with its own elastic restoring force, pushes the piston back to its initial position. This, in turn, drives the compression block to reset via the connecting rod, thus resetting the mechanism. This improves ease of use and ensures the inflation mechanism functions properly the next time the door is closed. It also allows the silicone strip to reset itself elastically when not in use, preventing accidental activation and damage when the door is opened due to its larger expanded size. The first guide rod slides within the second guide rod, providing guidance and constraint for the piston's reciprocating motion. This effectively prevents the piston from shifting or tilting during movement, ensuring the smoothness of the compression and reset process and reducing frictional wear between the piston and the inner wall of the air reservoir. Simultaneously, the return spring is sleeved on both the second and first guide rods. These two guide rods limit the spring's movement, preventing it from bending or twisting during expansion and contraction, extending its lifespan and ensuring the long-term reliability of the reset function.

[0022] Furthermore, the gas supply assembly includes a connecting pipe, which is installed on the side end face of the gas storage pipe, and the end of the connecting pipe facing away from the gas storage pipe is installed in the cavity of the silicone strip.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] The connecting pipe directly connects the air storage pipe to the cavity of the silicone strip, which can deliver the gas in the air storage pipe to the cavity of the silicone strip, ensuring that the silicone strip expands to the required size in a short time and matches the sealing strip of the car body to achieve instant sealing of the door gaps.

[0025] This utility model provides a fully sealed off-road vehicle cab structure. It has the following advantages:

[0026] When the door is closed, the compression component triggers the air storage component to supply air. The silicone strip expands rapidly and fits tightly against the body sealing strip, filling the gap between the door and the body. Even when the off-road vehicle is traveling on rough roads and undergoes bumps and deformation, it can still maintain a stable sealing effect, effectively preventing external dust, mud, sand and other debris from entering the cab, creating a clean interior environment for the driver and passengers. This also prevents the sealing strip from shifting or deforming under the combined effects of repeated vibration, sudden temperature changes and mud and sand erosion, which could cause gaps between the sealing surfaces.

[0035] 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.

[0036] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows: Example

[0037] A fully sealed off-road vehicle body cab structure includes an off-road vehicle body 1, on which a cab door 2 is installed;

[0038] A silicone strip 3 is fitted to the inner wall of the driver's cab door 2. The silicone strip 3 is used to seal the gaps in the door after inflation. A cavity is opened inside the silicone strip 3.

[0039] An inflation mechanism 4 is installed inside the cab door 2. The inflation mechanism 4 is used to inflate the cavity of the silicone strip 3, causing the silicone strip 3 to expand.

[0040] The inflation mechanism 4 includes a compression component, an air storage component, a reset component, and an air supply component. The compression component is used to squeeze the gas in the air storage component after contacting the vehicle body to supply air. The air storage component is used to store and supply air. The reset component is used to reset the compression component. The air supply component is used to supply air to the cavity of the silicone strip 3. By refining the inflation mechanism 4 into a compression component, an air storage component, a reset component, and an air supply component, the compression component provides inflation power, the air storage component ensures gas reserves, the reset component ensures the reusability of the mechanism, and the air supply component delivers gas. The multiple components improve the stability and reliability of the inflation process, thereby ensuring that the silicone strip 3 can expand stably to achieve a seal. Even under the complex working conditions of bumpy off-road driving, it can maintain a good sealing state.

[0041] The air storage component includes an air storage pipe 406, which is installed inside the cab door 2. As the core component for air storage, the air storage pipe 406 needs to be installed in the empty space inside the cab door 2 for use. The air storage pipe 406 can store a certain amount of gas. When the compression component is working, it can supply air to the cavity of the silicone strip 3, so that the silicone strip 3 can start to expand when the door is closed, thereby improving the sealing reaction speed and preventing external dust and mud from entering the cab.

[0042] The extrusion assembly includes an extrusion block 401, on which a silicone pad 402 is fitted. A connecting rod 404 is mounted on the extrusion block 401 via a screw 403. A piston 405 is mounted on the end of the connecting rod 404 opposite to the extrusion block 401. The piston 405 is slidably sleeved within the air storage pipe 406. When the extrusion block 401 contacts the vehicle body, the silicone pad 402 on its surface can buffer the contact impact force through its own elastic deformation. This not only reduces the hard wear between the extrusion block 401 and the vehicle body, extending their service life, but also reduces collision noise when closing the door, improving the driving experience. The extrusion block 401 is connected to the connecting rod 404 via the screw 403. The extension length of the extrusion block 401 can be adjusted by rotating the screw 403, thereby adjusting the extrusion force according to the actual gap between the door and the vehicle body, ensuring that the piston 405 can generate appropriate pressure on the gas in the air storage pipe 406. The piston 405 fits tightly against the inner wall of the air storage pipe 406. When sliding, it can efficiently squeeze the gas in the air storage pipe 406, and stably convert the mechanical energy of closing the door into gas pressure, providing sufficient and stable power for inflating the silicone strip 3.

[0043] The reset assembly includes a second guide rod 408 and a reset spring 409. Both the second guide rod 408 and the reset spring 409 are installed inside the air storage pipe 406. A first guide rod 407 is slidably sleeved inside the second guide rod 408. Both the first guide rod 407 and the reset spring 409 are connected to the piston 405. The reset spring 409 is sleeved on the second guide rod 408 and the first guide rod 407. When the door is opened and the compression assembly is no longer under force, the reset spring 409 can push the piston 405 back to its initial position by its own elastic restoring force. Then, through the connecting rod 404, it drives the compression block 401 to reset, realizing the reset of the mechanism, improving the ease of use, ensuring that the inflation mechanism 4 can work normally when the door is closed next time, and allowing the silicone strip 3 to reset by its own elasticity when not in use, avoiding accidental contact and damage caused by its large volume after expansion when the door is opened. The first guide rod 407 slides within the second guide rod 408, providing guidance and constraint for the reciprocating motion of the piston 405. This effectively prevents the piston 405 from shifting or tilting during movement, ensuring the smoothness of the compression and reset process and reducing frictional wear between the piston 405 and the inner wall of the gas storage pipe 406. Simultaneously, the reset spring 409 is sleeved on the second guide rod 408 and the first guide rod 407. The two guide rods limit the spring's movement, preventing it from bending or twisting during extension and retraction, extending the service life of the reset spring 409, and ensuring the long-term reliability of the reset function.

[0044] The air supply assembly includes a connecting pipe 410, which is installed on the side end face of the air storage pipe 406. The end of the connecting pipe 410 facing away from the air storage pipe 406 is installed in the cavity of the silicone strip 3. The connecting pipe 410 directly connects the air storage pipe 406 and the cavity of the silicone strip 3, and can deliver the gas in the air storage pipe 406 to the cavity of the silicone strip 3, ensuring that the silicone strip 3 expands to the required size in a short time to match the sealing strip of the vehicle body, thereby achieving instant sealing of the door gaps.

[0045] Furthermore, the silicone strip 3 on the driver's cab door 2 needs to be installed around the door frame. This is not fully shown in the diagram, and personnel need to install the silicone strip 3 according to their needs.

[0046] Working principle:

[0047] When the cab door 2 is closed, the compression block 401 of the inflation mechanism 4 first comes into contact with the vehicle body;

[0048] The vehicle body exerts pressure on the extrusion block 401, and the extrusion block 401 drives the connecting rod 404 to move toward the air storage pipe 406 via the screw 403.

[0049] The connecting rod 404 pushes the piston 405 to slide inside the gas storage tube 406, compressing the gas stored inside the gas storage tube 406;

[0050] The compressed gas is delivered to the cavity of the silicone strip 3 through the connecting pipe 410 of the gas supply assembly;

[0051] The silicone strip 3 expands as gas is filled into the cavity, and fits tightly against the sealing strip of the car body to seal the gaps in the door.

[0052] When the cab door 2 is opened, the pressure of the vehicle body on the compression block 401 disappears;

[0053] The reset spring 409 of the reset assembly pushes the piston 405 to move away from the air outlet of the air storage pipe 406 by its own elastic restoring force.

[0054] Piston 405 drives the extrusion block 401 to reset via connecting rod 404 and screw 403;

[0055] Meanwhile, the silicone strip 3 contracts due to its own elasticity, and the gas in the cavity flows back to the air storage pipe 406 (or is discharged through its own elasticity), waiting to repeat the above process when the car door is closed next time.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
