Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a heavy-duty truck floating seat adjustment mechanism. Background Technology

[0002] In the heavy truck transportation industry, drivers often need to maintain a fixed sitting posture for long periods of time while driving. The comfort and support of the seat directly affect the driver's driving performance and physical health.

[0003] Most heavy-duty truck seats on the market currently use traditional sponge pads as the core cushioning structure. While this structure can provide basic support, its cushioning and shock absorption performance is limited. Especially when heavy-duty trucks are driving on bumpy roads, it cannot effectively alleviate the impact of road bumps on the driver's body. Long-term use can easily lead to fatigue and soreness in the driver's waist, back, and neck, and even cause chronic strain problems. It is difficult to meet the comfort needs of long-term driving scenarios. In order to improve the shock absorption effect, some heavy-duty truck seats will install additional shock-absorbing damping components at the bottom. However, this design not only increases the overall structural complexity and manufacturing cost of the seat, but also occupies more installation space at the bottom of the seat, which limits the lightweight and compact design of the seat.

[0004] To address the shortcomings of the aforementioned technologies, we propose a heavy-duty truck suspended seat adjustment mechanism. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heavy-duty truck suspension seat adjustment mechanism.

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

[0007] A heavy-duty truck suspended seat adjustment mechanism includes a suspended seat support mechanism and an airbag buffer adjustment mechanism. The airbag buffer adjustment mechanism includes an airbag pad and a silent air pump. A lumbar support airbag, a back support airbag, and a neck support airbag are sequentially fixedly connected to the airbag pad. A first air pipe and a second air pipe are connected to the silent air pump. An inflation / deflation air pipe is connected to the side of the first air pipe. The inflation / deflation air pipe is connected to the lumbar support airbag, the back support airbag, and the neck support airbag, respectively. An electromagnetic control air valve is provided between the inflation / deflation air pipe and the airbag pad, the lumbar support airbag, the back support airbag, and the neck support airbag. An air pressure sensor is provided inside the airbag pad, the lumbar support airbag, the back support airbag, and the neck support airbag.

[0008] Furthermore, the suspended seat support mechanism includes a support plate and a back plate, a weighing plate is fixedly installed at the bottom of the support plate, and a structural plate is fixedly installed at the bottom of the weighing plate.

[0009] By adopting the above technical solution, the weighing pan can detect the total weight on its upper side, the seat adjustment controller can receive its weight information, and then subtract the structural weight to obtain the driver's weight. Subsequently, the air pressure inside the basic airbag cushion is automatically adjusted according to the weight to complete the basic support adaptive adjustment of the entire airbag buffer adjustment mechanism. The driver can then make further adjustments according to their own needs.

[0010] Furthermore, a seat adjustment controller is fixedly installed on the side of the back panel, and an electrical interface is provided on the side of the seat adjustment controller.

[0011] Furthermore, the airbag cushion is L-shaped, and the back of the airbag cushion is fixedly bonded to the support plate and the back plate respectively.

[0012] By adopting the above technical solution, the electrical interface provides a connection channel with the vehicle's infotainment system, and the entire seat adjustment process is controlled by the heavy truck's infotainment system, improving operational convenience.

[0013] Furthermore, a dust cover is fitted over the second tracheal tube port.

[0014] Furthermore, protective edges are symmetrically fixedly connected to both sides of the airbag cushion.

[0015] By adopting the above technical solution, the dust cover prevents dust from entering the silent air pump, thus providing protection for the silent air pump.

[0016] Furthermore, a neck-protecting notch is provided in the middle of the neck support airbag.

[0017] Furthermore, a bearing seat is fixedly installed on the right side of the support plate, a self-locking servo motor is fixedly installed on the side of the bearing seat, a rotating shaft is rotatably installed in the middle of the bearing seat, the output end of the self-locking servo motor is fixedly connected to the rotating shaft, and the bottom of the back plate is fixedly connected to the rotating shaft.

[0018] By adopting the above technical solution, the self-locking servo motor can drive the rotating shaft to rotate when it starts, thereby adjusting the tilt angle of the back panel and the entire seat back tilt angle. The tilt angle adjustment range is relatively high. The self-locking servo motor has self-locking performance and can restrict the rotational freedom of the rotating shaft after adjustment.

[0019] Furthermore, a limiting gear disc is fixedly installed at the other end of the rotating shaft. A structural cover is provided on the outer side of the limiting gear disc. The structural cover is screwed onto the side wall of the shaft seat. An electric push rod is fixedly installed on the side wall of the structural cover. The output end of the electric push rod slides through into the interior of the structural cover, and a limiting engagement tooth is fixedly installed on the output end of the electric push rod.

[0020] Furthermore, the structural disk is provided with a number of screw mounting holes evenly distributed on it.

[0021] By adopting the above technical solution, after the tilt angle adjustment is completed, the electric push rod starts to push the limiting engagement teeth on its output end to mesh with the limiting gear plate at the end of the rotating shaft, thereby completing the limitation of the free rotation end of the other end of the rotating shaft. This forms a double limiting mechanism with the self-locking servo motor, which improves the structural stability after the tilt angle adjustment is completed.

[0022] Compared with related technologies, the heavy-duty truck suspension seat adjustment mechanism proposed in this utility model has the following beneficial effects:

[0023] This utility model describes a heavy-duty truck suspended seat adjustment mechanism. Compared to traditional sponge pad designs, the airbag cushioning adjustment mechanism improves comfort by providing beneficial cushioning and shock absorption, eliminating the need for reinstalling shock-absorbing dampers at the bottom of the seat. The mechanism includes four independent airbag spaces: an airbag cushion, a lumbar support airbag, a back support airbag, and a neck support airbag. The airbag cushion provides support and shock absorption, enhancing comfort. The lumbar support airbag, back support airbag, and neck support airbag support areas prone to driver fatigue, further improving comfort. Each airbag space is independently designed, and its firmness can be independently controlled by a silent air pump through inflation and deflation, allowing adjustment according to the driver's needs. The entire seat structure is lightweight and highly adaptable. Attached Figure Description

[0031] 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.

[0032] Reference Figures 1-6 A heavy-duty truck suspension seat adjustment mechanism includes a suspension seat support mechanism 1 and an airbag buffer adjustment mechanism 2. The airbag buffer adjustment mechanism 2 includes an airbag pad 21 and a silent air pump 27. A lumbar support airbag 23, a back support airbag 24, and a neck support airbag 25 are sequentially fixedly connected to the airbag pad 21. A first air pipe 28 and a second air pipe 29 are connected to the silent air pump 27. An inflation / deflation air pipe 211 is connected to the side of the first air pipe 28. The inflation / deflation air pipe 211 is connected to the airbag pad 21, the lumbar support airbag 23, the back support airbag 24, and the neck support airbag 25, respectively. An electromagnetic control air valve is provided between the inflation / deflation air pipe 211 and the airbag pad 21, the lumbar support airbag 23, the back support airbag 24, and the neck support airbag 25. An air pressure sensor is provided inside the airbag pad 21, the lumbar support airbag 23, the back support airbag 24, and the neck support airbag 25.

[0033] Through the above structure, the silent air pump 27 can deliver gas to the inflation / deflation air passage 211 through the first air pipe 28. Each electromagnetically controlled air valve can independently control the air passage between the inflation / deflation air passage 211 and the airbag cushion 21, lumbar support airbag 23, back support airbag 24, and neck support airbag 25, so as to realize the individual inflation / deflation of each airbag. At the same time, the air pressure sensor inside each airbag can monitor the air pressure value of the corresponding airbag in real time and feed the data back to the seat adjustment controller 13 so as to accurately control the softness and hardness of each airbag and meet the driver's personalized needs for support comfort in different parts. It should be noted that a face mask needs to be installed on the outside of the entire airbag cushioning adjustment mechanism 2. The face mask can wrap the entire airbag cushioning adjustment mechanism 2 inside, and is made of skin-friendly material. It can be customized according to the driver's usage needs.

[0034] In this embodiment, the suspended seat support mechanism 1 includes a support plate 11 and a back plate 12. A weighing plate 15 is fixedly installed at the bottom of the support plate 11, and a structural plate 16 is fixedly installed at the bottom of the weighing plate 15. Several screw mounting holes are evenly distributed on the structural plate 16.

[0035] Through the above structure, the weighing pan 15 can detect the total weight of the upper side of the support plate 11 (including the airbag buffer adjustment mechanism 2 and the driver) in real time, and transmit the weight data to the seat adjustment controller 13; the seat adjustment controller 13 can automatically calculate the driver's actual weight according to the preset structural weight parameters (weight of components such as support plate 11 and back plate 12), and then adjust the initial air pressure of the airbag cushion 21 based on the weight data to achieve adaptive matching of the basic support; the screw mounting holes on the structural plate 16 make it convenient to fix the entire suspended seat support mechanism 1 to a designated position in the cab of the heavy truck by bolts, ensuring the stability of the installation.

[0036] In this embodiment, a bearing seat 17 is fixedly installed on the right side of the support plate 11, a self-locking servo motor 18 is fixedly installed on the side of the bearing seat 17, a rotating shaft 19 is rotatably installed in the middle of the bearing seat 17, the output end of the self-locking servo motor 18 is fixedly connected to the rotating shaft 19, and the bottom of the back plate 12 is fixedly connected to the rotating shaft 19.

[0037] With the above structure, when the seat backrest tilt angle needs to be adjusted, the seat adjustment controller 13 can control the self-locking servo motor 18 to start. The output end of the self-locking servo motor 18 drives the rotating shaft 19 to rotate within the bearing seat 17. The bottom of the back panel 12 is fixedly connected to the rotating shaft 19. Therefore, when the rotating shaft 19 rotates, it will synchronously drive the back panel 12 to rotate around the axis of the rotating shaft 19, thereby realizing the adjustment of the backrest tilt angle. Moreover, the self-locking servo motor 18 has a self-locking function. After the tilt angle is adjusted to the correct position, it can lock the rotational freedom of the rotating shaft 19 to prevent the back panel 12 from shifting due to vibration or other factors during use, thus ensuring the stability of the tilt angle.

[0038] In this embodiment, a limiting gear 110 is fixedly installed at the other end of the rotating shaft 19. A structural cover 111 is provided on the outer side of the limiting gear 110. The structural cover 111 is screwed onto the side wall of the shaft seat 17. An electric push rod 112 is fixedly installed on the side wall of the structural cover 111. The output end of the electric push rod 112 slides through into the interior of the structural cover 111, and a limiting engagement tooth 113 is fixedly installed on the output end of the electric push rod 112.

[0039] With the above structure, after the self-locking servo motor 18 completes the tilt adjustment of the back panel 12 and self-locks, the seat adjustment controller 13 can further control the electric push rod 112 to start. The output end of the electric push rod 112 pushes the limiting engagement tooth 113 to move towards the limiting gear plate 110 until the limiting engagement tooth 113 and the teeth of the limiting gear plate 110 mesh with each other. At this time, the limiting gear plate 110 is fixedly connected to the rotating shaft 19, and the limiting engagement tooth 113 is fixed on the bearing seat 17 through the structural cover 111, thereby forming a mechanical limit on the other end of the rotating shaft 19. This forms a double limiting mechanism with the self-locking function of the self-locking servo motor 18, which greatly improves the structural stability after the tilt adjustment and avoids the rotating shaft 19 from loosening due to the bumps of the heavy truck driving.

[0040] In this embodiment, a seat adjustment controller 13 is fixedly installed on the side of the back panel 12, and an electrical interface 14 is provided on the side of the seat adjustment controller 13.

[0041] With the above structure, the seat adjustment controller 13 can serve as the control core of the entire adjustment mechanism, receiving data transmitted from components such as the weighing pan 15 and the air pressure sensor, and controlling the actions of actuators such as the silent air pump 27, the electromagnetic control air valve, the self-locking servo motor 18, and the electric push rod 112 according to the preset program or the driver's operation instructions (such as adjustment requirements input through the vehicle system). The electrical interface 14 enables the seat adjustment controller 13 to be electrically connected to the heavy truck system, allowing it to obtain power from the vehicle system and enabling the driver to adjust the seat through convenient operation methods such as the vehicle screen or steering wheel buttons, without the need for an additional independent control panel, thus improving ease of use.

[0042] In this embodiment, the airbag cushion 21 is L-shaped, and the back of the airbag cushion 21 is fixedly bonded to the support plate 11 and the back plate 12 respectively. A dust cover 210 is fitted at the port of the second air tube 29.

[0043] With the above structure, the L-shaped airbag cushion 21 can be precisely adapted to the shape of the support plate 11 (seat surface) and the back plate 12 (backrest), and a stable installation can be achieved through fixed bonding, ensuring that the airbag cushion 21 will not shift when supporting the driver's body; the second air pipe 29 serves as the air intake channel of the silent air pump 27, and the dust cover 210 at its port can effectively block dust and impurities in the air from entering the silent air pump 27, avoiding dust accumulation that could cause wear or blockage of the internal components of the air pump, and extending the service life of the silent air pump 27.

[0044] In this embodiment, protective edges 22 are symmetrically fixedly connected to both sides of the airbag cushion 21.

[0045] With the above structure, the side guards 22 on both sides of the airbag cushion 21 can provide a certain wrapping and restraining effect on the sides of the driver's body when the driver is riding, preventing the driver's body from sliding to the sides when the heavy truck is turning or driving on bumpy roads, thus improving the stability and safety of the ride; at the same time, the side guards 22 can also protect the sides of the airbag cushion 21, reducing friction wear between the airbag cushion 21 and other components such as the seat frame.

[0046] In this embodiment, a neck-protecting notch 26 is provided in the middle of the neck support airbag 25.

[0047] With the above structure, the neck support recess 26 in the middle of the neck support airbag 25 can fit the physiological curve of the driver's neck, so that when the neck support airbag 25 is inflated, it can more accurately support the driver's neck and avoid the neck being suspended or the support point shifting. This design can effectively distribute neck pressure, relieve neck muscle fatigue caused by long-term driving, and further improve the comfort and ergonomic fit of the seat.

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.
