The EZE seat is an electrically operated, fully liftable, easy-entry car seat. It uses an electric mechanism to move the seat forward and flip it up, thereby creating more spacious entry and exit space for rear passengers.

[0003] The existing middle row seats cannot simultaneously achieve diverse seat configuration adjustments such as longitudinal sliding, backrest folding, and overall flipping, thus failing to meet the usage needs of diverse scenarios. Summary of the Invention

[0004] Therefore, this utility model provides an electric EZE seat frame and a car seat, which can realize various form changes such as longitudinal (horizontal) sliding, backrest reclining and overall flipping, and can meet the usage needs of diverse scenarios.

[0005] To solve the above-mentioned technical problems, this utility model provides an electric EZE seat frame, comprising: Front vehicle body mounting bracket; An electric slide rail assembly includes a horizontal slide rail and a flip bracket connected to the front end of the horizontal slide rail and rotatably connected to the front vehicle mounting bracket. The seat cushion frame is slidably connected to the horizontal slide rail; A horizontal drive device is disposed between the seat cushion frame and the horizontal slide rail, for driving the seat cushion frame to slide along the horizontal slide rail; The backrest frame is rotatably connected to one end of the seat cushion frame; The first electric angle adjuster assembly is disposed between the backrest frame and the seat cushion frame and is used to drive the backrest frame to rotate. The second electric angle adjuster assembly is mounted on the front vehicle mounting bracket and is used to drive the electric slide rail assembly to rotate.

[0006] In one embodiment of this utility model, the rear end of the seat cushion frame extends upward in a horizontal direction with two mounting arms, and the lower end of the backrest frame is rotatably connected between the two mounting arms.

[0008] In one embodiment of this utility model, the horizontal drive device includes a horizontal motor arranged within the seat cushion frame and a transmission assembly disposed between the drive end of the horizontal motor and the horizontal slide rail.

[0009] In one embodiment of this utility model, the first electric angle adjuster assembly includes a backrest motor and a first synchronizing rod connected to the backrest motor. The first synchronizing rod is connected between the mounting arm and the lower end of the backrest frame.

[0010] In one embodiment of this utility model, the second electric angle adjuster assembly includes an EZE flip motor and a second synchronizing rod connected to the drive end of the EZE flip motor. The second synchronizing rod is connected between the front vehicle mounting bracket and the flip bracket.

[0011] In one embodiment of this utility model, it further includes a vehicle body floor lock, a floor lock assembly, a cable motor, and a pull cable. The floor lock assembly is connected to a horizontal slide rail, and the drive end of the cable motor is connected to the floor lock assembly through the pull cable.

[0032] Reference Figure 1 As shown, an electric EZE seat frame (for automobile seats) includes: Front vehicle body mounting bracket 1; The electric slide rail assembly 2 includes a horizontal slide rail 21 and a flip bracket 22 connected to the front end of the horizontal slide rail 21 and rotatably connected to the front vehicle mounting bracket 1. The seat frame 3 is slidably connected to the horizontal slide rail 21; A horizontal drive device 4 is disposed between the seat cushion frame 3 and the horizontal slide rail 21, and is used to drive the seat cushion frame 3 to slide along the horizontal slide rail 21. The backrest frame 5 is rotatably connected to one end of the seat cushion frame 3; The first electric angle adjuster assembly 6 is disposed between the backrest frame 5 and the seat cushion frame 3, and is used to drive the backrest frame 5 to rotate. The second electric angle adjuster assembly 7 is mounted on the front vehicle mounting bracket 1 and is used to drive the electric slide rail assembly 2 to rotate.

[0033] It should be noted that the front vehicle mounting bracket 1 provides a stable mounting support surface. This structure connects the tilting bracket 22 to the overall seat, forming a reliable rotation fulcrum, which facilitates the rotation of the electric slide rail assembly 2 during tilting motion.

[0034] In one embodiment, the rear end of the seat cushion frame 3 extends upward in a horizontal direction with two mounting arms 31, and the lower end of the backrest frame 5 is rotatably connected between the two mounting arms 31.

[0035] In one embodiment, the horizontal slide rail 21 is provided with two parallel lines, and the front ends of the two horizontal slide rails 21 are connected to the upper end of the flipping bracket 22.

[0036] The electric sliding rail assembly 2 consists of two parallel horizontal sliding rails 21 and a flip bracket 22 located at the front end. This structure has both forward and backward sliding and overall flipping freedom. The horizontal sliding rails 21 ensure smooth displacement of the seat along the longitudinal direction of the vehicle body, while the rotatable connection between the flip bracket 22 and the front vehicle body mounting bracket 1 allows the seat to be raised and flipped forward as a whole, which helps to simplify the layout, reduce the installation height, improve the utilization of interior space and the convenience of passenger entry and exit.

[0037] In one embodiment, refer to Figure 2 As shown, the horizontal drive device 4 includes a horizontal motor 41 arranged in the seat frame 3 and a transmission assembly 42 (transmission rod, transmission gear, lead screw assembly, etc.) disposed between the drive end of the horizontal motor 41 and the horizontal slide rail 21.

[0038] The seat frame 3 is slidably mounted on the horizontal slide rail 21, capable of bearing the weight of the occupant and achieving smooth forward and backward movement. The frame incorporates reinforcing ribs and a mounting arm 31 structure, which improves bending stiffness and facilitates the integrated arrangement of the horizontal motor 41, transmission components 42, etc. This design enhances the structural strength of the frame, ensuring the seat's stability and reliability during sliding and tilting, reducing vibration and noise, and improving riding comfort.

[0039] In one embodiment, refer to Figure 2 As shown, the first electric angle adjuster assembly 6 includes a backrest motor 61 and a first synchronizing rod 62 connected to the backrest motor 61. The first synchronizing rod 62 is connected between the mounting arm 31 and the lower end of the backrest frame 5.

[0040] In one embodiment, refer to Figure 2 As shown, the second electric angle adjuster assembly 7 includes an EZE flip motor 71 and a second synchronizing rod 72 connected to the drive end of the EZE flip motor 71. The second synchronizing rod 72 is connected between the front body mounting bracket 1 and the flip bracket 22.

[0041] It should be noted that the detailed structures of the horizontal drive device 4, the first electric angle adjuster assembly 6, and the second electric angle adjuster assembly 7 are existing mature technologies and will not be described in detail here.

[0042] The backrest frame 5 is rotatably connected to the seat cushion frame 3 at one end, and the backrest angle can be electrically adjusted under the drive of the first electric angle adjuster assembly 6. This structure can realize the switching of multiple postures such as sitting, semi-reclining and flat, to meet the different riding needs of passengers. At the same time, it keeps in sync with the seat cushion frame 3 when the seat is flipped up, so as to avoid interference or misalignment.

[0043] In one embodiment, refer to Figure 4 , Figure 5 As shown, it also includes a vehicle body lock 81, a lock assembly 82, a cable motor 83, and a pull cable 84. The lock assembly 82 is connected to the horizontal slide rail 21. The drive end of the cable motor 83 is connected to the lock assembly 82 through the pull cable 84. The lock assembly 82 can cooperate with the vehicle body lock 81 to lock or unlock.

[0044] Specifically, the vehicle body floor lock 81 includes a floor lock mounting plate 811, a receiving groove 812 disposed on the floor lock mounting plate 811, and a locking rod 813 connected to the upper end of the receiving groove 812; The ground lock assembly 82 includes a mounting bracket 821 connected to the horizontal slide rail 21, a locking bracket 822 connected to the mounting bracket 821, and a locking hook assembly 85 installed in the locking bracket 822. The locking hook assembly 85 includes a rotating arm 851, a tension spring 852, a locking hook arm 853, and a locking hook 854, and the locking bracket 822 is provided with a locking groove 8221; One end of the locking arm 853 is rotatably connected to the locking bracket 822 and the other end is connected to the locking hook 854; One end of the rotating arm 851 is rotatably connected to the locking bracket 822; the other end of the rotating arm 851 is connected to the pull line 84 via a horizontal steel wire rope 855. The two ends of the tension spring 852 are respectively connected to one end of the locking hook arm 853 and the rotating arm 851; The locking hook 854 can close or open the locking groove 8221 when the locking hook arm 853 rotates, and the tension spring 852 can provide the force to rotate the locking hook arm 853 and close the locking groove 8221 with the locking hook 854. When the electric slide rail assembly 2 is flipped, the cable motor 83 can drive the horizontal steel wire rope 855 through the pull wire 84 to open the locking groove 8221. When the electric slide rail assembly 2 is reset, the locking hook 854 and the locking rod 813 can open the locking groove 8221 when they collide, and the locking rod 813 enters the locking groove 8221, while the locking hook 854 is accommodated in the accommodating groove 812.

[0045] Specifically, the floor lock assembly 82 is installed at the rear end of the horizontal slide rail 21.

[0046] By cooperating with the vehicle body lock 81 and the floor lock assembly 82 located at the rear end of the horizontal slide rail 21, automatic locking and unlocking can be achieved before and after the EZE flips over. Remote unlocking is completed by the cable motor 83 driving the pull cable 84 and the horizontal steel wire rope 855, without manual intervention. This structure ensures the stability and safety of the seat while the vehicle is in motion, preventing accidental displacement or loosening of the seat.

[0047] Furthermore, the locking hook assembly 85 adopts a mechanical self-resetting design. When the electric slide rail assembly 2 resets, the locking hook 854 automatically collides with the locking rod 813 to complete the locking. The tension spring 852 provides continuous locking force to ensure a secure lock. This solution can complete mechanical detection and position self-resetting without additional sensors, improving system reliability and lifespan, and ensuring the stable fixation of the entire structure in dynamic environments.

[0048] The working principle of this utility model is as follows: Reference Figures 6 to 8 As shown, when the EZE flip function is executed, firstly, the backrest motor 61 drives the first electric angle adjuster assembly 6, which drives the backrest frame 5 to flip forward relative to the seat cushion frame 3 around the first synchronous rod 62, so that the backrest frame 5 gradually flattens from the sitting position and forms a flattened state. Subsequently, the horizontal motor 41 drives the seat frame 3 to slide forward along the horizontal slide rail 21 via the internal transmission assembly 42, thereby moving the entire seat assembly forward. Next, the cable motor 83 drives the horizontal steel wire rope 855 through the pull wire 84, causing the ground lock assembly 82 to disengage from the steel wire of the vehicle ground lock 81, thereby unlocking the ground lock. Once the ground lock is completely released, the EZE flip motor 71 starts working, and its output drives the second synchronous rod 72 in the second electric angle adjuster assembly 7 to rotate, which in turn pushes the flip bracket 22 connected to it to rotate around the front body mounting bracket 1 at its front end, so that the electric slide rail assembly 2 and the seat cushion frame 3 it carries flip forward as a whole, realizing the EZE flip state.

[0049] When the EZE reset function is executed, the EZE flip motor 71 rotates in the opposite direction, driving the second synchronous rod 72 to rotate in the opposite direction, thereby driving the flip bracket 22 to drive the electric slide rail assembly 2 and the seat frame 3 to flip and reset backward around the front vehicle mounting bracket 1. During the reset process, the floor lock assembly 82 moves backward with the slide rail and comes into contact with the steel wire of the vehicle floor lock 81. The lock hook 854 opens the locking groove 8221 under the action of the locking rod 813. When the locking rod 813 enters the receiving groove 812, the tension spring 852 provides the reset force, so that the lock hook 854 closes the locking groove 8221 and completes the automatic locking. Subsequently, the horizontal motor 41 drives the seat cushion frame 3 to move backward along the horizontal slide rail 21 to the designed position. The backrest motor 61 then drives the first electric angle adjuster assembly 6, causing the backrest frame 5 to rotate backward from the flat state around the first synchronous rod 62 to the normal sitting angle, thus completing the entire EZE reset process.

[0050] The electric EZE seat frame achieves automated switching between sitting, reclining, and forward-folding modes through multi-motor coordinated control of the sliding rail translation, backrest tilting, and seat forward tilting. The linkage between the first and second electric angle adjusters, the horizontal drive device 4, and the floor lock system ensures the safety and reliability of the action sequence. The entire mechanism is compact and operates smoothly, significantly improving the convenience of rear passengers getting in and out of the vehicle and the flexible utilization efficiency of the interior space.

[0051] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
