Description

Technical Field

[0001] The present invention relates to the field of vehicle seats, and in particular to a foldable seat for a new energy logistics vehicle. Background Art

[0002] In the field of new energy logistics vehicles, the comfort and functionality of vehicle seats have a significant impact on the driver's driving experience and work efficiency. Traditional logistics vehicle seats mostly adopt a fixed structure, and the shape and angle of the lumbar support part cannot be adjusted according to the human body shape and driving needs. During long-distance driving, the driver's waist is very likely to suffer from fatigue, soreness and other problems due to lack of effective support, and even cause lumbar spine diseases. In addition, traditional seats cannot eliminate the gap between the waist and the bottom of the seat, resulting in incomplete support, further reducing comfort. At the same time, logistics vehicle drivers have high work intensity and limited rest time. After the seat is laid flat, the lumbar support part of the chair back is often still relatively protruding, which will press against the user's waist, making it difficult to meet the driver's needs for temporary rest during transportation. Therefore, we propose a folding new energy logistics vehicle seat to solve the above-mentioned problems. Summary of the Invention

[0007] Preferably, the release assembly further comprises an electric push rod 1, which is rotatably connected to the lower rear portion of the back support plate, and one end of the electric push rod 1 away from the back support plate is rotatably connected to the end of the shell.

[0008] Preferably, the rear portions of both sides of the lumbar support plate are fixedly connected with connecting springs, and the ends of the connecting springs away from the lumbar support plate are rotatably connected to both sides of the front portion of the chair back frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention improves driving comfort through a dynamic lumbar support structure. In actual use, a servo motor drives the fixed shaft to rotate, and the gear plate and the gear column engage to drive the adjustment plate to rotate in the slide groove. The lumbar support plate is pushed out by the gradually curved side of the adjustment plate, so that the lumbar support plate is bent to form an arc that conforms to the human waist curve. At the same time, the electric push rod pushes the push plate to fine-tune the position of the adjustment plate, realizing dynamic adjustment of the lumbar support curvature and strength, effectively alleviating fatigue from long-distance driving.

[0017] 2. The present invention eliminates the lumbar support gap by releasing the assembly. The stepping motor drives the active bevel gear to rotate, and the rotating shaft is rotated through the driven bevel gear. The threaded section drives the adjusting rod to move along the limit rod, and the connecting rod drives the support frame to lift the bottom of the lumbar support plate to eliminate the gap between the waist and the bottom of the seat. The limit rod ensures the linear movement of the adjusting rod, ensures the support accuracy and stability, and enhances the lumbar fit integrity. At the same time, it cooperates with the adjustment disk to synchronously adjust the curvature curve of the upper and lower parts of the lumbar support plate, so that it can better fit the human body.

[0018] 3. The present invention cooperates with the release component to provide dynamic support during driving. During rest, the servo motor drives the straight side of the adjustment disk to fit the slide groove to eliminate the curvature of the lumbar support plate. The stepper motor folds the support frame to make the bottom of the lumbar support plate lose support. At the same time, the electric push rod contracts and drives the lumbar support plate to swing backward. Combined with the elastic support of the connecting spring, the lumbar support plate and the chair back are integrated into a lying plane to meet the short-distance rest needs of logistics vehicles. At the same time, the connecting springs on both sides of the lumbar support plate are rotatably connected to the chair back frame to provide elastic buffering during the adjustment process to avoid rigid vibration; the gear plate and the gear column engage with the pawl to prevent slipping, and the bevel gear transmission ensures efficient power transmission of the release component and guarantees the structural stability of the components when they work together.

[0019] 4. The present invention controls the linkage of the servo motor, stepper motor and electric push rod through the vehicle-mounted system, and can complete the lumbar support curvature, protrusion adjustment and seat flatness without manual adjustment, adapting to the one-button operation requirements in driving scenarios and improving ease of use. At the same time, through the folding and flattening function of the release component and the adjustment component, the seat back is converted into a flat surface, creating a temporary rest space in the cab of the logistics vehicle. Combined with the chassis sliding structure, it can realize the combination of space utilization and functional practicality, meeting the multi-scenario usage needs of logistics drivers.

[0033] Furthermore, during specific implementation, if the user feels that there is a gap between the bottom of the lumbar support plate 105 and the bottom of the seat, the stepper motor 109 can be further started, and the stepper motor 109 can drive the active bevel gear 123 to rotate, and the active bevel gear 123 drives the driven bevel gear 124 to rotate the rotating shaft 114, and the threaded sections 115 on both sides of the rotating shaft 114 can drive the adjustment rod 116 to move outward along the limit rod 122, and the connecting rod 117 can drive the support frame 112 to swing, and the support frame 112 can lift the bottom of the lumbar support plate 105 to eliminate the gap.

In this process, the connecting spring 106 provides elastic support to ensure structural stability, providing the driver with a comfortable rest space.

[0036] Working principle:

[0037] When the driver of a new energy logistics vehicle feels waist fatigue during long-distance driving, the seat adjustment function can be activated through the vehicle system. The protruding curvature of the lumbar support plate 105 can be adjusted through the adjustment component to support the user's waist. First, the servo motor starts to run, driving the fixed shaft 125 to rotate, and the gear plate 126 and the gear column 127 are engaged and transmitted, driving the adjustment disks 110 at both ends of the rotating rod 128 to rotate in the slide grooves 120 of the horizontal and vertical bars 113. The arc-shaped side of the adjustment disk 110 gradually pushes out the lumbar support plate 107, so that the lumbar support plate 105 is bent to form a shape that meets the user's waist. The curvature of the waist curve of the body can be adjusted, and the electric push rod 108 can push the waist support plate 107 to yaw and fine-tune the position and angle of the waist support plate 107 and the waist support plate 105, thereby greatly enhancing the support strength and comfort of the vehicle seat for the waist. At the same time, the electric push rod 2 130 can push the push plate 129 to fine-tune the position of the adjustment disk 110 and increase the adjustment range of the adjustment disk 110 and enhance the support strength when needed. If the user feels that there is a gap between the bottom of the waist support plate 105 and the bottom of the seat, the stepper motor 109 can be further started to adjust the waist support plate 107 and the waist support plate 105. The stepper motor 109 can drive the active bevel gear 123 to rotate, and the active bevel gear 123 drives the driven bevel gear 124 to rotate the shaft 114. The threaded sections 115 on both sides of the shaft 114 can drive the adjusting rod 116 to move outward along the limit rod 122, and the connecting rod 117 can drive the support frame 112 to swing. The support frame 112 lifts the bottom of the waist support plate 105 to eliminate the gap. When the driver needs to take a short break during the long-distance logistics process, the user can start the release component through the vehicle system to release the The vehicle seat is switched to "rest mode". After the vehicle seat is laid flat, the servo motor drives the adjustment plate 110 to fit the straight side of the slide groove 120 to eliminate the curvature of the lumbar support plate 105. The stepper motor 109 drives the support frame 112 to swing and fold so that the bottom of the lumbar support plate 105 loses support. At the same time, the electric push rod 108 contracts and drives the lumbar support plate 107 to swing backward, finally integrating the lumbar support plate 105 with the seat back into a lying plane. During this process, the connecting spring 106 provides elastic support to ensure structural stability, providing the driver with a comfortable rest space.
