Technical Field
[0001] The invention relates to the technical field of automobile accessories, and in particular to a front electric seat posture adjustment tool. Background Art
[0002] Cars have become an indispensable means of transportation in people's production and life. Logistics and home travel are inseparable from cars. At present, my country's car ownership ranks first, the number of private cars is increasing day by day, and the market share of new energy vehicles is soaring. As a new type of transportation, electric vehicles are energy-saving and environmentally friendly, reduce exhaust emissions, have low maintenance and repair costs, and are quiet and comfortable in the car. They play a more diverse role in home life. Thanks to the advantages of large batteries, the application of electricity in cars is more diverse, such as watching movies in the car, outdoor picnics, self-driving travel, electric adjustment seats, zero-gravity seats, etc., which are gradually popularized in new car-making forces.
[0003] Among them, electric adjustment seats are equipped in models manufactured by many car manufacturers, and are also divided into high and low grades. From entry-level to flagship models, different levels of electric adjustment seat modes are set respectively, and a boss button is set on the highest-configuration flagship model, that is, the passengers in the rear seats can use the boss button to adjust the displacement and backrest angle of the front seats forward and backward to expand the legroom and field of vision in the rear row, while the second-highest configuration and below models are not equipped with this function. However, in actual life travel, the legroom of the rear passengers is still affected by the rearward movement of the front driver or co-driver seat, and the rear riding experience is poor. A typical example is: when an online car-hailing vehicle is carrying passengers, the legroom in the back row is too small, and the driver is expected to adjust the front passenger seat forward. However, the front passenger seat can only be adjusted from the manual control button on the passenger seat. Currently, there are few adjustment solutions that support voice control, and boss seats are only available in high-end models. Even if the driver has adjusted the passenger seat forward in advance, when sharing a ride on the online car-hailing vehicle, the passenger will still sit on the passenger seat, and the seat will still be adjusted backward. The driver has to frequently manually adjust the passenger seat forward and backward, which is extremely inconvenient.
[0004] Based on the above reasons, there are still many vehicles in the society that have non-adjustable front electric seats in the rear row, and the solution of modifying the electric seats with wired or wireless remote control will damage the seat electronic control circuit, causing the vehicle's electronic control to be tampered with, directly affecting the vehicle's overall warranty and lifetime three-electric warranty. Therefore, there are very few cases in the market where private car owners choose to modify the electric adjustment seats. They can only buy special models at a high price. The second-top, mid-range and low-end models cannot use the function of adjusting the front seats from the rear row. Summary of the invention
[0005] The purpose of the present invention is to enable rear passengers to adjust the front electric seats, move the seats forward or backward, and adjust the backrest angle to obtain more leg room and sight space in the rear row. We have designed and proposed a front electric seat posture adjustment tool to greatly improve the riding space for rear passengers, reduce the sense of space oppression, and expand the field of vision.
[0006] The technical solutions adopted to solve the above problems are:
[0007] A front row electric seat posture adjustment tool comprises a pressing transmission mechanism for driving a backrest button to rotate forward or reversely by manually transmitting a pressing force from a rear row passenger, and a pushing transmission mechanism for driving a seat cushion button to move forward or backward by manually transmitting a pushing force from a rear row passenger.
[0008] The pressing transmission mechanism and the pushing transmission mechanism each independently adopt a mechanical arm to cooperate with the backrest knob mounted on the backrest button and the seat cushion push button mounted on the seat cushion button, and respectively provide pressing force and push-pull force to the backrest knob and the seat cushion push button, that is, the pressing transmission mechanism includes a first mechanical arm and the backrest knob, and the backrest knob and the backrest button are driven to rotate synchronously by rotating the first mechanical arm, and the pushing transmission mechanism includes a second mechanical arm and the seat cushion push button, and the seat cushion push button and the seat cushion button are driven to push and pull synchronously by pushing and pulling the second mechanical arm.
[0009] The backrest knob is provided with a pressing transmission component for shortening the rotation radius of the backrest knob.
[0010] The pressing transmission mechanism and the pushing transmission mechanism use a mechanical arm to cooperate with the backrest knob mounted on the backrest button and the seat cushion push button mounted on the seat cushion button, and provide pressing force and push-pull force to the backrest knob and the seat cushion push button respectively. That is, the pressing transmission mechanism includes a third mechanical arm, a pressing transmission assembly, and a backrest knob. The pressing transmission assembly is driven to rotate by rotating the third mechanical arm, and the backrest knob and the backrest button are driven to rotate synchronously. The pushing transmission mechanism includes a third mechanical arm, a pushing transmission assembly, and a seat cushion push button. The pushing transmission assembly is driven to slide linearly by pushing and pulling the third mechanical arm, and the seat cushion push button and the seat cushion button are driven to push and pull synchronously.
[0011] Furthermore, a lever fulcrum is provided in the middle of the mechanical arm, and the mechanical arm can slide and rotate around the lever fulcrum.
[0012] The pressing transmission assembly includes a rotating arm and a hinge pin. One end of the rotating arm is fixedly connected to the backrest knob, and the other end is provided with a long waist-shaped hole parallel to the push-pull direction of the seat cushion button. The long waist-shaped hole is movably hinged to the front end of the third mechanical arm through the hinge pin. As the front end of the third mechanical arm is pressed up and down, and the hinge pin slides in the long waist-shaped hole, the rotating arm rotates around the rotating axis of the backrest button as the axis.
[0013] The push transmission assembly includes a fourth mechanical arm and an articulated seat. One end of the fourth mechanical arm is movably hinged to the third mechanical arm through a hinge pin, and the other end is connected to the articulated seat through a movable pin. The articulated seat is fixedly connected to the seat cushion push button.
[0014] Furthermore, a movable gap is provided at the movable hinge between the fourth mechanical arm and the articulated seat to prevent spatial interference after the fourth mechanical arm rotates, and the size of the movable gap is smaller than the distance that the hinge pin axis in the long waist-shaped hole is pushed forward or pulled backward.
[0015] Furthermore, the forward or backward displacement dimension of the hinge pin in the long waist-shaped hole is greater than the dimension required by the seat cushion button to control the forward or backward displacement of the seat cushion.
[0016] Furthermore, the first mechanical arm, the second mechanical arm and the third mechanical arm are positioned on the side of the seat through a limiting leather cover.
[0017] The beneficial effects of the present invention are:
[0018] 1. The front electric seat posture adjustment tool can adjust the angle of the front seat backrest upward or downward through one or two mechanical arms, and adjust the displacement of the front seat cushion forward or backward. Passengers do not need to go to the front row to manually adjust the electric seat button, and the adjustment can be achieved, which is convenient and practical;
[0019] 2. The posture adjustment tool is attached to the side of the front seat and can be provided with a protective shell, which has better concealment, improves the appearance, and does not affect the riding experience of the front seat passengers;
[0020] 3. A pull ring is set at the rear end of the mechanical arm, which is convenient for rear passengers to hold with one hand, and there is no sharp end, which does not affect the driving safety of the vehicle and the life safety of the passengers. The mechanical arm can also be attached to the side of the seat through a limited leather cover to prevent abnormal noise in the car;
[0021] 4. All mechanical arms can be set up to avoid the electric adjustment buttons, which will not affect the actual use of the original electric adjustment buttons by the front passengers;
[0022] 5. It is very friendly to vehicles on the market. By installing this tool, the front seats can be adjusted by mechanical transmission, instead of changing the electronic control of the vehicle through the circuit to achieve remote adjustment of the front seats, without affecting the owner's lifetime three-electric warranty and vehicle warranty rights;
[0023] 6. This tool is low-cost and has powerful functions. It can allow mid- and low-end models to enjoy the driving experience of high-end flagship models, and allow rear passengers to adjust the front electric seats at will to obtain more legroom and sight space in the back row.

DETAILED DESCRIPTION
[0036] The technical solution of the present invention will be clearly and completely described below in the form of embodiments in conjunction with the accompanying drawings.
[0037] Example 1 :
[0038] See also Figures 1 to 3 This embodiment proposes a front electric seat posture adjustment tool, including a pressing transmission mechanism that drives the backrest button 16 to rotate forward or reversely through the pressing force manually transmitted by the rear passengers, and a pushing transmission mechanism that drives the seat cushion button 18 to move forward or backward through the pushing force manually transmitted by the rear passengers.
[0039] See also Figure 2 and Figure 3 The pressing transmission mechanism and the pushing transmission mechanism adopt the third mechanical arm 11 to cooperate with the backrest knob 25 mounted on the backrest button 16 and the seat cushion push button 26 mounted on the seat cushion button 18, and provide pressing force and push-pull force to the backrest knob 25 and the seat cushion push button 26 respectively, that is, the pressing transmission mechanism includes the third mechanical arm 11, the pressing transmission assembly, and the backrest knob 25. The pressing transmission assembly is driven to rotate by rotating the third mechanical arm 11, and the backrest knob 25 and the backrest button 16 are driven to rotate synchronously. The pushing transmission mechanism includes the third mechanical arm 11, the pushing transmission assembly, and the seat cushion push button 26. The pushing transmission assembly is driven to slide linearly by pushing and pulling the third mechanical arm 11, and the seat cushion push button 26 and the seat cushion button 18 are driven to push and pull synchronously.
[0040] A further embodiment is to refer to Figure 2 and Figure 3 The lever fulcrum 12 may or may not be provided in the middle of the mechanical arm. A rotating sleeve 13 is provided on the lever fulcrum 12. The center of the rotating sleeve 13 is slidably matched with the third mechanical arm 11. The rotating sleeve 13 can rotate and match with the lever fulcrum 12 from the middle.
[0041] See also Figure 3 and Figure 6 The pressing transmission assembly includes a rotating arm 22 and a hinge pin 15. One end of the rotating arm 22 is fixedly connected to the backrest knob 25, and an avoidance groove 27 is opened in the middle of the other end, and a long waist-shaped hole 28 is provided parallel to the push-pull direction of the cushion button 18, so as to ensure that the third mechanical arm 11 and the fourth mechanical arm 20 can slide linearly in the long waist-shaped hole 28. The long waist-shaped hole 28 is movably hinged with the front end of the third mechanical arm 11 through the hinge pin 15. As the front end of the third mechanical arm 11 is pressed up and down, and the hinge pin 15 slides in the long waist-shaped hole 28, the rotating arm 22 rotates with the rotating axis 21 of the backrest button 16 as the axis, driving the backrest knob 25 to rotate synchronously at a rotation angular velocity much greater than the third mechanical arm 11, thereby reducing the displacement of the third mechanical arm 11 swinging up and down, so that the rear passengers can press the pull ring 8 up and down slightly to realize the rotation control of the backrest button 16.
[0042] The push transmission assembly includes a fourth mechanical arm 20 and an articulated seat 17 . One end of the fourth mechanical arm 20 is movably hinged to the third mechanical arm 11 via an articulated pin 15 , and the other end is connected to the articulated seat 17 via a movable pin. The articulated seat 17 is fixedly connected to the seat push button 26 .
[0043] A further embodiment is to refer to Figure 2 The movable hinge between the fourth mechanical arm 20 and the hinge seat 17 is provided with an active gap 19 to prevent spatial interference after the fourth mechanical arm 20 rotates, and the size of the active gap 19 is smaller than the distance that the hinge pin 15 in the long waist-shaped hole 28 is pushed forward or pulled backward.
[0044] A further embodiment is to refer to Figure 2 and Figure 6 The forward or backward displacement size of the hinge pin 15 in the long waist-shaped hole 28 is larger than the size required for the seat button 18 to control the forward or backward displacement of the seat cushion 3, so that the push-pull action of the third mechanical arm 11 can complete the stroke required for the forward or backward control action of the seat button 18.
[0045] A further embodiment is to refer to Figure 2 and Figure 3 The third mechanical arm 11 is positioned on the side of the seat through the limiting leather cover 9 to prevent vibration and abnormal noise during driving of the vehicle.
[0046] A further embodiment is to refer to Fig.11 Reset springs are symmetrically arranged in the long waist-shaped hole and on both sides of the hinge pin to limit the degree of freedom of the third and fourth mechanical arms in the axial direction and prevent the two mechanical arms from shaking, vibrating, and making abnormal noises.
[0047] Example 2 :
[0048] See also Figure 4 and Figure 5 The present embodiment proposes a front electric seat posture adjustment tool, including a pressing transmission mechanism that drives the backrest button 16 to rotate forward or reversely through the manual transmission of pressing force by the rear passengers, and a pushing transmission mechanism that drives the cushion button 18 to move forward or backward through the manual transmission of pushing force by the rear passengers. The difference from the embodiment 1 is that the pressing transmission mechanism and the pushing transmission mechanism each use a separate mechanical arm to cooperate with the backrest knob 25 sleeved on the backrest button 16 and the seat cushion push button 26 sleeved on the seat cushion button 18, and provide pressing force and push-pull force to the backrest knob 25 and the seat cushion push button 26 respectively, that is, the pressing transmission mechanism includes a first mechanical arm 23 and the backrest knob 25, and the backrest knob 25 and the backrest button 16 are driven to rotate synchronously by rotating the first mechanical arm 23, and the pushing transmission mechanism includes a second mechanical arm 24 and the seat cushion push button 26, and the seat cushion push button 26 and the seat cushion button 18 are driven to push and pull synchronously by pushing and pulling the second mechanical arm 24.
[0049] Example 3 :
[0050] See also Figures 1 to 3 This embodiment proposes a front electric seat posture adjustment tool, including a pressing transmission mechanism that drives the backrest button 16 to rotate forward or reversely through the pressing force manually transmitted by the rear passengers, and a pushing transmission mechanism that drives the seat cushion button 18 to move forward or backward through the pushing force manually transmitted by the rear passengers. The difference from Example 1 is that the pressing transmission assembly includes a rotating arm 22 and a hinge pin 15, one end of the rotating arm 22 is fixedly connected to the backrest knob 25, and the middle part of the other end is provided with a long waist-shaped hole 28 parallel to the push-pull direction of the seat cushion button 18, the long waist-shaped hole 28 is movably hinged to the front end of the third mechanical arm 11 through the hinge pin 15, and the fourth mechanical arm 20 is provided with a Y-shaped hinge end 29, and the Y-shaped hinge end 29 is hinged to the hinge pin 15. As the front end of the third mechanical arm 11 is pressed up and down, and the hinge pin 15 slides in the long waist-shaped hole 28, the rotating arm 22 rotates with the rotating axis 21 of the backrest button 16 as the axis, driving the backrest knob 25 to rotate synchronously at a rotation angular velocity much greater than the third mechanical arm 11, thereby reducing the displacement of the third mechanical arm 11 swinging up and down, so that the rear passengers can press the pull ring 8 up and down slightly to achieve rotation control of the backrest button 16.
[0051] By analogy, the connection structure between the third robotic arm 11, the fourth robotic arm 20 and the rotating arm 22, as long as it is a structural principle that achieves the same transmission purpose of the present invention, should fall within the protection scope of this application.
[0052] Example 4:
[0053] See also Figures 1 to 3 This embodiment proposes a front row electric seat posture adjustment tool, including a pressing transmission mechanism that drives the backrest button 16 to rotate forward or reversely through the pressing force manually transmitted by the rear passenger, and a pushing transmission mechanism that drives the seat cushion button 18 to move forward or backward through the pushing force manually transmitted by the rear passenger. The difference from the embodiment 1 is: Fig. 9 and Fig.10 , the third mechanical arm 11, the fourth mechanical arm 20 and the rotating arm 22, under the premise of satisfying the transmission structure principle described in Example 1, avoid the contact position of each electric control button of the front electric seat by adjusting their own structure, so as to facilitate the front passenger to autonomously adjust the seat posture, including but not limited to the bending posture adjustment of the third mechanical arm 11, the bending posture adjustment of the rotating arm 22 and the bending posture adjustment of the fourth mechanical arm 20, but the movable pin, the hinge pin 15 and the initial posture of the third mechanical arm 11 remain collinear;
[0054] When the third mechanical arm 11 is pushed to move the seat forward, the hinge connecting the third mechanical arm 11 and the fourth mechanical arm 20 is at a dead point, that is, a very small force is decomposed in a direction perpendicular to the third mechanical arm 11 and the fourth mechanical arm 20, and the decomposed force is much smaller than the force of pressing the backrest button 16 to rotate it, and the remaining thrust can directly push the cushion button 18 forward;
[0055] When the third mechanical arm 11 is pulled to move the seat backward, the third mechanical arm 11 pulls the fourth mechanical arm 20, and the pulling force is fully applied to the seat cushion button 18, and the seat is pulled backward to move the seat backward.
[0056] The above describes in detail the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes, modifications, substitutions and variations can be made within the knowledge scope of ordinary technicians in the field without departing from the spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
