Description

Technical Field

[0001] This utility model belongs to the field of driver's seat technology, specifically relating to a heavy truck driver's seat that is easy to install. Background Technology

[0002] The driver's seat in a heavy-duty truck cab is a core driver support device adapted to the long-distance and complex operating conditions of heavy-duty trucks. It is not simply an enlarged version of a regular passenger car seat, but a functional configuration with "anti-fatigue and strong protection" as its core. It is designed for the 8-12 hours of driving required by heavy-duty truck drivers per day, making the support system particularly crucial. The lumbar support is multi-directionally adjustable to conform to the lumbar curve and relieve pressure on the lower back; the backrest angle and seat cushion length can also be adjusted as needed to avoid soreness caused by the legs being unsupported.

[0003] However, the existing seat installation structure has obvious shortcomings in terms of adjustment convenience and hole matching; its adjustment mechanism lacks synchronous reverse design, and is mostly single-sided independent adjustment or single screw unidirectional drive, which leads to asynchronous adjustment of the spacing of the fixed parts on both sides, which is prone to millimeter-level deviation. Repeated manual calibration is required to get close to the target size, making the adjustment process cumbersome and inefficient. Utility Model Content

Detailed Implementation

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1-5 This utility model provides an easy-to-install heavy-duty truck driver's seat, including a seat body 1. A support frame 2 is fixedly connected to the bottom of the seat body 1, and the support frame 2 supports the seat body 1. A fixing rod 3 is installed at the bottom of the support frame 2 via an adjustment assembly. The adjustment assembly includes an adjustment groove 301 formed at the bottom of the support frame 2. A double-acting screw 302 is rotatably connected inside the adjustment groove 301. The two ends of the double-acting screw 302 are provided with a pair of threads in opposite directions. An adjustment slider 303 is slidably connected inside the adjustment groove 301 in a linear array. A pair of adjustment sliders 303 are symmetrically installed. A limiting groove 304 is symmetrically distributed at the bottom of the support frame 2 on both sides of the adjustment groove 301. The fixing rod 3 is slidably connected to the limiting groove 304. Inside the groove 304, the cross-sections of the fixed rod 3 and the limiting slide groove 304 are both T-shaped. The adjusting slide groove 301 is connected to the limiting slide groove 304 through the connecting groove 305 opened on the side wall. The adjusting slider 303 is fixedly connected to the fixed rod 3 through the connecting block on the side. By adjusting the movement of the slider 303, the fixed rod 3 moves synchronously. The rear end of the support frame 2 is rotatably connected to a knob 306 for the operator to rotate the double-acting screw 302. The fixed rod 3 has an installation hole 4 inside for installing fixing bolts, so that the device can be stably installed on the heavy truck. The adjusting slider 303 is threadedly connected to the double-acting screw 302 through the threaded hole 307 opened inside. The knob 306 passes through the rear end of the support frame 2 and is fixedly connected to one end of the double-acting screw 302.

[0018] The adjustment assembly is configured such that when knob 306 is rotated, it drives the bidirectional lead screw 302 to rotate within the adjustment groove 301. Since the adjusting slider 303 is threadedly connected to the bidirectional lead screw 302 via an internal threaded hole 307, the rotation of the bidirectional lead screw 302 causes the adjusting slider 303 to slide in opposite directions or away from each other along the adjustment groove 301. The adjusting slider 303 is fixedly connected to the fixed rod 3 via a side connecting block and a connecting groove 305, thereby driving the fixed rod 3 to slide synchronously within the T-shaped limiting groove 304, thus achieving adjustment of the spacing between the fixed rods 3. In this invention, the reverse thread design of the bidirectional lead screw 302 enables the adjusting slider 303 to move synchronously in the opposite direction, ensuring precise and efficient adjustment of the spacing of the fixing rods 3. The T-shaped fixing rod 3 cooperates with the limiting slide groove 304, enhancing the stability of the sliding process and preventing the fixing rod 3 from falling off or shifting. The knob 306 is easy for staff to operate manually, allowing adjustment of the spacing of the fixing rods 3 without the need for professional tools. It is compatible with different mounting hole positions on the heavy truck, significantly improving installation convenience. The mounting hole 4 provides a foundation for bolt fixing, ensuring the structural stability of the seat after installation.

[0019] Specifically, such as Figure 4 and Figure 5 As shown, a storage block 5 is fixedly connected to the top of the fixing rod 3. A protective cover 6 is installed inside the storage block 5 through a sliding component to protect the mounting hole 4 and the bolts inside, preventing the mounting hole 4 from being blocked or the bolts from rusting, thus improving the convenience of installing and removing the seat. A sealing block 7 is fixedly connected to the top of the fixing rod 3 and at the front end of the storage block 5 to seal the opening of the protective cover 6, preventing dust and other impurities from entering the mounting hole 4.

[0020] The protective cover 6 and the sealing block 7 of this utility model effectively protect the mounting hole 4 and the internal bolts, preventing the mounting hole 4 from being blocked or the bolts from being corroded, ensuring the normal use of the bolts and mounting hole 4 during subsequent disassembly and assembly, and improving the ease of disassembly and assembly; the storage block 5 has a storage function for the protective cover 6, so that the protective cover 6 can be hidden when not in use, without occupying extra space and keeping the structure neat.

[0021] Specifically, such as Figure 4 and Figure 5 As shown, the sliding assembly includes a storage groove 501 opened at the front end of the storage block 5, and a protective cover 6 slidably connected inside the storage groove 501. A helical spring 502 is fixedly connected inside the storage groove 501 to facilitate the reset and movement of the protective cover 6. The other end of the helical spring 502 is fixedly connected to the protective cover 6. The protective cover 6 is U-shaped, and the opening of the protective cover 6 is adapted to the sealing block 7. A second limiting groove 503 is opened on the side wall of the storage groove 501, and a limiting block adapted to the second limiting groove 503 is provided on the side of the protective cover 6 to limit the movement of the protective cover 6.

[0022] In this utility model, the sliding component is designed such that the protective cover 6 is slidably connected to the storage groove 501 at the front end of the storage block 5. One end of the spiral spring 502 in the storage groove 501 is fixed to the storage groove 501, and the other end is fixed to the protective cover 6. When the protective cover 6 is pulled open, the spiral spring 502 stretches and stores force. After being released, the spiral spring 502 resets and drives the protective cover 6 to automatically slide back to the closed position. The protective cover 6 is U-shaped, and its opening is adapted to the sealing block 7 to form a tight seal when closed. The limiting block on the side of the protective cover 6 cooperates with the limiting groove 503 on the side wall of the storage groove 501 to limit the sliding trajectory of the protective cover 6 and prevent it from falling out of the storage groove 501.

[0023] Specifically, such as Figure 5 As shown, a lever 601 is fixedly connected to the top of the protective cover 6, making it easy for workers to move the protective cover 6 before installing the bolts. The protective cover 6 is positioned directly above the mounting hole 4, improving the accuracy of the protection. The lever 601 makes opening the protective cover 6 easier and more convenient, requiring no additional tools. The design of the protective cover 6 being positioned directly above the mounting hole 4 ensures that it will not obstruct the mounting hole 4 after opening, avoiding interference with the installation operation and further enhancing the convenience of seat installation.

[0024] Working principle and usage process of this utility model: When using this utility model, the operator first places the seat body 1 in a suitable position on the heavy truck, and then rotates the knob 306 at the rear end of the support frame 2. The knob 306 drives the bidirectional lead screw 302 to rotate. Since the adjusting slider 303 is slidably connected in the adjusting groove 301 and is threadedly connected to the bidirectional lead screw 302 through the threaded hole 307 inside, the rotation of the bidirectional lead screw 302 will cause the adjusting slider 303 to slide in opposite directions or away from each other along the adjusting groove 301. The adjusting slider 303 is then fixedly connected to the fixing rod 3 through the connecting block on the side and the connecting groove 305, thereby driving the fixing rod 3 to slide synchronously in the limiting groove 304 to realize the adjustment of the spacing of the fixing rod 3. Subsequently, the fixing bolts are installed through the mounting hole 4 inside the fixing rod 3 to stably fix the seat on the heavy truck. Meanwhile, in the sliding assembly, when the operator moves the protective cover 6 by using the lever 601 fixed at the top of the protective cover 6, the protective cover 6 slides open along the receiving groove 501, exposing the mounting hole 4 directly below it for installing bolts. After releasing the lever 601, the coil spring 502 resets and drives the protective cover 6 back to the closed position. At this time, the opening of the "U"-shaped protective cover 6 matches the sealing block 7 fixed at the top of the fixing rod 3, sealing the opening of the protective cover 6 and preventing dust and other debris from entering the mounting hole 4, thus protecting the mounting hole 4 and the internal bolts.
