Description

Technical Field

[0001] This invention relates to the field of vehicle seating, and in particular to a seat, a vehicle comfort system, and a vehicle. Background Technology

[0002] Most vehicle seats currently in use are equipped with airbags and shock absorption devices to improve safety and ride comfort. Higher-end seats, in addition to having electric adjustment, heating, ventilation and massage functions, also have the function of shock absorption in the longitudinal, lateral and vertical directions.

[0003] Although current seats have good vibration damping in the longitudinal, lateral, and vertical directions, they can still generate centrifugal force when a vehicle is cornering, especially when cornering at high speed. This centrifugal force can be quite large, and even with a seatbelt, the occupants may still tilt or move in the direction of the centrifugal force. In severe cases, the excessive centrifugal force may even cause injury to the occupants and endanger their personal safety. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a seat, body comfort system and vehicle that overcomes or at least partially solves the above problems.

[0005] In a first aspect, a seat is provided, the seat comprising: a seat panel and a seat base;

[0006] The bottom of the seat panel is fixed with multiple seat brackets, and each seat bracket is equipped with a pulley at the bottom.

[0007] The seat base has a certain curvature, and the concave surface is provided with multiple transverse sliding tracks;

[0008] Multiple pulleys are slidably connected to the multiple transverse slide rails;

[0009] The central pulley is slidably connected to the central slide of the multiple transverse slides, and the central pulley is the pulley at the bottom of the central seat bracket corresponding to the center position of the seat plate;

[0010] The central slide rail has a partial recess corresponding to the center position of the bottom of the seat plate, forming a recessed area. The radius of the cross-sectional circle corresponding to the arc of the recessed area is smaller than the radius of the cross-sectional circle corresponding to the arc of the central slide rail.

[0011] The central pulley is positioned within the recessed area under preset conditions;

[0012] The top of the central seat support is fixedly connected to the center position of the bottom of the seat plate via an elastic device.

[0013] Optionally, under non-preset conditions, the plurality of pulleys slide along their respective transverse slides toward the centrifugal force direction, wherein the central pulley leaves the recessed portion and slides along the central slide toward the centrifugal force direction;

[0014] When the multiple pulleys slide towards the centrifugal force direction, they cause the seat plate to make a small circular motion along the center of the cross-sectional circle corresponding to the arc of the transverse slide.

[0015] When the seat base performs the small circular motion of the seat plate, it applies a lateral force to the seat plate that is opposite to the direction of the centrifugal force.

[0016] Optionally, the slide includes any of the following types of slides:

[0017] Angular slides, I-shaped slides, trapezoidal slides, and cylindrical slides.

[0018] Optionally, the resilient device includes any of the following:

[0019] Metal springs, rubber springs, ceramic springs, carbon nanotube springs.

[0020] Optionally, the preset condition is: the centrifugal force on the seat is not greater than the force required to keep the central pulley in the recessed area;

[0021] The non-preset condition is: the centrifugal force on the seat is greater than the force that keeps the central pulley in the recessed area.

[0022] Optionally, the seat further includes: a lateral damping device;

[0023] The lateral damping device includes: a lateral spring, a lateral damper, and a lateral stop;

[0024] The lateral spring, the lateral damper, and the lateral stop are installed between the mounting plates on both sides of the upper part of the seat base and the mounting plates on both sides of the seat plate.

[0025] Optionally, the force that keeps the central pulley in the recessed portion refers to the sum of the forces generated by the transverse spring, the transverse damper, and the preload generated by the elastic device.

[0026] Optionally, the seat further includes: a vertical shock absorption device;

[0027] The vertical damping device includes: a vertical spring, a vertical damper, and a vertical stop;

[0028] The vertical spring, the vertical damper, and the vertical stop are installed between the vehicle floor and the seat base frame.

[0029] In a second aspect, a vehicle comfort system is provided, the vehicle comfort system including a seat as described in any of the first aspects.

[0030] Thirdly, a vehicle is provided that includes a seat as described in any of the first aspects.

[0031] The embodiments of this application have the following advantages:

[0032] In this invention, the seat includes a seat panel and a seat base. The bottom of the seat panel and the seat base are connected by multiple seat brackets, pulleys, and slide rails. Each seat bracket has a pulley at its bottom, and the concave surface of the seat base has multiple transverse slide rails. The pulleys are slidably connected to the transverse slide rails. Since the person sits on the seat panel, and the seat panel and seat base can slide, this lays the foundation for attenuating or even offsetting the effects of centrifugal force on the person.

[0033] The central pulley is slidably connected to the central slide rail, which has a recessed area. Under preset conditions, the central pulley is located within the recessed area. The top of the central seat support is fixedly connected to the center position of the bottom of the seat board via an elastic device.

[0034] The elastic device at the top of the central seat support, combined with other parts of the seat, allows the central pulley to move away from or remain in the recessed area based on the magnitude of the centrifugal force. If the central pulley moves away from the recessed area, it indicates a large centrifugal force, which can affect the comfort of the occupants and even endanger their safety. All pulleys slide on the track in the direction of the centrifugal force, thereby causing the seat plate (effectively moving the occupants) to make a small circular motion along the transverse track. The seat base can then apply a transverse force to the seat plate in the opposite direction of the centrifugal force, thus attenuating or even counteracting the adverse effects of centrifugal force on the occupants and reducing the probability of personal injury. The seat of this invention has high practicality. Attached Figure Description

[0039] Figure 4 This is an exemplary schematic diagram of a seat sliding in an embodiment of the present invention. Detailed Implementation

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention, and are only some, not all, embodiments of the present invention, and are not intended to limit the present invention.

[0041] The seat of this invention includes: a seat panel and a seat base frame; the seat panel is the part of the seat that supports the occupants of the vehicle, and the seat base frame is generally fixedly installed on the vehicle body floor, providing support for the entire seat. Multiple seat supports are fixed to the bottom of the seat panel, and each seat support has a pulley at its bottom; the seat base frame has a certain curvature and multiple transverse tracks on its concave surface; the multiple pulleys and multiple transverse tracks are slidably connected, allowing the seat panel and seat base frame to slide against each other, laying the foundation for attenuating or even offsetting the effects of centrifugal force on the occupants.

[0042] The seat support corresponding to the center position of the seat panel is defined as the central seat support. The pulley at the bottom of the central seat support is called the central pulley. The central pulley is slidably connected to the central slide rail among multiple transverse slide rails. It can be understood that the central slide rail refers to the transverse slide rail connected to the central pulley. The projection of this slide rail on the bottom of the seat panel passes laterally through the center position of the seat panel, rather than being defined by the center position of multiple transverse slide rails.

[0043] A recessed section on the central slide rail, corresponding to the center of the seat base, forms a concave area. The radius of the cross-sectional circle corresponding to the arc of this recessed area is smaller than the radius of the cross-sectional circle corresponding to the arc of the central slide rail. The purpose of this recessed area is to ensure that the central pulley is positioned within the recessed area under predetermined conditions. Additionally, the top of the central seat support is fixedly connected to the center of the seat base bottom via an elastic device. The other seat supports are rigidly fixed to the seat base bottom. The reason for the elastic connection of the central seat support will be explained below and will not be repeated here.

[0044] To more clearly illustrate the seat of the present invention, refer to... Figure 1 This diagram illustrates a three-dimensional model of the seat as described in an embodiment of the present invention, including all vibration damping devices present in the seat. It is understood that other known parts of the seat, such as the seat back, seat cushion, and adjustment devices, can also be applied to this seat, but for the sake of simplicity, not all are shown. (See reference...) Figure 2 The diagram shows a three-dimensional model of the seat rear view according to an embodiment of the present invention. Figure 3The diagram shows a three-dimensional model of the pulley and slide rail in an embodiment of the present invention.

[0045] Figure 1 It includes: seat plate 1, seat base frame 2, seat bracket 3, pulley 4, lateral slide rail 5, recessed part 6, lateral spring 7, lateral shock absorber 8, lateral stop 9, vertical spring 10, vertical shock absorber 11, vertical stop 12, and vehicle body floor plate 13. Figure 1 The example shows five seat supports 3 and three transverse slides 5. The actual number of seat supports 3 can be determined according to actual needs, as long as the seat board and the person sitting on the seat board are stable. The number of casters 4 is consistent with the number of seat supports 3. The number of transverse slides 5 is determined according to the distribution of the seat supports, for example... Figure 1 Except for the central seat bracket 301, the other seat brackets shown are located at the four corners of the seat plate. Therefore, three lateral sliding rails 5 are needed to connect all the pulleys 4.

[0046] In this embodiment of the invention, the slide 5 includes any of the following types of slides: angle slide, I-shaped slide, trapezoidal slide, and cylindrical slide.

[0047] Elastic devices include any of the following: metal springs, rubber springs, ceramic springs, and carbon nanotube springs.

[0048] like Figure 3 As shown, the pulley in the recessed part 6 is the central pulley 401, which is slidably connected to the central slide rail 501.

[0049] The top of the central support 301 is fixedly connected to the center position of the bottom of the seat plate 1 via an elastic device, such as... Figure 2 As shown, Figure 2 Specifically, spring 302 is used as an example to represent the elastic device. There is a mounting plate 201 on each side of the upper part of the seat base 2, and a mounting plate 101 on each side of the seat panel. The function of mounting plates 101 and 201 is to install and fix the lateral damping device. The lateral damping device includes: a lateral spring 7, a lateral damper 8, and a lateral stop 9, installed between mounting plates 101 and 201. The lateral spring 7 and lateral damper 8 in the lateral damping device are used to dampen the lateral vibration of the seat, and the lateral stop 9 is used to prevent excessive lateral displacement of the seat.

[0050] The seat of the present invention further includes: a vertical damping device, which includes: a vertical spring 10, a vertical damper 11, and a vertical stop 12. Figure 1It can be seen that the vertical spring 10, the vertical damper 11, and the vertical stop 12 are installed between the vehicle floor 13 and the seat base 2. Similar to the function of the lateral device, the vertical spring 10 and the vertical damper 11 in the lateral damping device are used to dampen the vertical vibration of the seat, and the vibration stop 12 is used to prevent the seat from having excessive vertical displacement.

[0051] In the seat of this invention, the central pulley 401 is positioned within the recessed portion 6 under preset conditions. The preset conditions refer to the following: the centrifugal force acting on the seat is not greater than the force required to maintain the central pulley within the recessed portion; the non-preset conditions refer to the following: the centrifugal force acting on the seat is greater than the force required to maintain the central pulley within the recessed portion. The force required to maintain the central pulley within the recessed portion refers to the sum of the forces generated by the transverse spring 7, the transverse damper 8, and the preload generated by the elastic device 201.

[0052] The principle behind the seat attenuation and even offsetting of the adverse effects caused by centrifugal force, thereby reducing the probability of personal injury, is as follows: When the centrifugal force is not greater than the sum of the force generated by the transverse spring 7, the transverse damper 8, and the pre-pressure generated by the elastic device 201, it indicates that the centrifugal force is small and has little impact on the passenger's comfort, let alone endangering their safety. At this time, the central pulley 401 is located in the recessed part 6, and the seat attenuates the transverse and vertical vibrations through the transverse damping device and the vertical damping device, but the seat will not slide.

[0053] When the centrifugal force exceeds the sum of the forces generated by the transverse spring 7, the transverse damper 8, and the preload generated by the elastic device 201, it indicates a large centrifugal force, which significantly impacts passenger comfort and may even endanger passenger safety. In this case, the central pulley 401 will disengage from the recessed area 6, and all pulleys 4 will slide along their respective tracks 5 towards the direction of the centrifugal force. As all pulleys 4 slide towards the direction of the centrifugal force, they will cause the seat plate 1 to make a small circular motion along the center of the cross-section corresponding to the arc of the track 5. (Refer to...) Figure 4 The sliding diagram shown is as follows. Figure 4 For the sake of simplicity, the horizontal device is not shown.

[0054] When the seat plate 1 makes a small circular motion along the center of the cross-section corresponding to the arc of the slide rail 5, the force applied by the seat base frame 2 to the seat plate 1 becomes a lateral force opposite to the centrifugal force. Simultaneously, it can convert some of the lateral vibration energy into gravitational potential energy, improving the subjective experience of the occupants. This lateral force can attenuate or even counteract the unbalanced centrifugal acceleration experienced by the seat 1 and the occupants, thereby attenuating or even counteracting the adverse effects caused by centrifugal force and reducing the probability of personal injury. At the same time, the seat can still attenuate lateral and vertical vibrations through lateral and vertical vibration damping devices. The seat as a whole achieves vibration damping for lateral, vertical, and centrifugal forces, demonstrating high practicality.

[0055] Based on the above-described seats, embodiments of the present invention also provide a vehicle comfort system, the vehicle comfort system including any of the seats described above.

[0056] Based on the above-described seats, embodiments of the present invention also provide a vehicle, the vehicle including any of the seats described above.

[0057] Through the above embodiments, in the seat of the present invention, when the centrifugal force is greater than the sum of the forces generated by the lateral spring, the lateral damper, and the preload generated by the elastic device, indicating a large centrifugal force, the central pulley will disengage from the recessed area, and all pulleys will slide along their respective tracks towards the direction of the centrifugal force. As all pulleys slide towards the direction of the centrifugal force, they will cause the seat plate to make a small circular motion along the center of the cross-section corresponding to the arc of the track. At this time, the force applied by the seat base frame to the seat plate will have a lateral force opposite to the direction of the centrifugal force. Simultaneously, some lateral vibration energy can be converted into gravitational potential energy, improving the subjective experience of the person. This lateral force can attenuate or even offset the unbalanced centrifugal acceleration experienced by the seat and the person, thereby attenuating or even offsetting the adverse effects caused by centrifugal force and reducing the probability of personal injury. At the same time, the seat can still attenuate lateral and vertical vibrations through the lateral and vertical damping devices. The seat as a whole achieves vibration reduction for lateral, vertical, and centrifugal forces, and has high practicality.
