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

[0003] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a folding new energy logistics vehicle seat.

[0006] Preferably, the release assembly includes a stepper motor, which is installed at the lower rear side of the lumbar support plate. A driving end of the stepper motor is fixedly connected with a driving bevel gear on its outer periphery. A driven bevel gear is meshed and connected to the front of the driving bevel gear. A rotating shaft is fixedly connected to the middle of the driven bevel gear. Threaded sections are provided at both ends of the outer periphery of the rotating shaft. Adjusting rods are threadedly connected to both sides of the outer periphery of the rotating shaft through the threaded sections. Fixing rings evenly distributed are fixedly connected to the outer peripheries of the adjusting rods. Connecting rods are rotatably connected to the front and rear sides of the fixing rings. Support frames are rotatably connected to the ends of the connecting rods far away from the fixing rings. Connecting rods are rotatably connected to the ends of the support frames far away from the connecting rods.

[0007] Preferably, the release assembly further includes an electric push rod I, which is rotatably connected to the lower rear side of the back support plate. An end of the electric push rod I far away from the back support plate is rotatably connected to the end of the housing.

[0008] Preferably, connecting springs are fixedly connected to the rear parts of both sides of the lumbar support plate. Ends of the connecting springs far away from the lumbar support plate are rotatably connected to both sides of the front part of the chair back frame.

[0009] Preferably, one side of each adjusting disc is set to be flat, and the other side of each adjusting disc is set to be a gradually changing arc.

[0010] Preferably, the push plates are fitted into the middle of one side of the outer periphery of the adjusting discs, and the adjusting discs are arranged inside the sliding grooves.

[0014] Preferably, connecting plates are installed at the rear ends of the rear connecting rods, and the connecting plates are all arranged inside the vehicle seat.

[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. During actual use, a servo motor drives a fixed shaft to rotate. Through the meshing of a toothed disc and a toothed column, the adjusting disc is driven to rotate in the sliding groove. The gradually changing arc side of the adjusting disc is used to push out the lumbar support plate, so that the lumbar support plate bends to form a radian conforming to the human lumbar curve. At the same time, an electric push rod II is used to push the push plate to finely adjust the position of the adjusting disc, realizing the dynamic adjustment of the lumbar support curvature and strength, and effectively relieving the fatigue of long-distance driving.

[0017] 2. The present invention eliminates the lumbar support gap through the release component. The stepping motor drives the rotation of the driving bevel gear, which causes the rotating shaft to rotate through the driven bevel gear. The threaded section is used to drive the adjusting rod to move along the limiting rod, and the support frame is driven by the connecting rod to lift the bottom of the lumbar support plate, eliminating the gap between the waist and the seat bottom. The limiting rod ensures the linear movement of the adjusting rod, guarantees the support accuracy and stability, enhances the integrity of the lumbar fit, and can synchronously adjust the arc curves of the upper and lower parts of the lumbar support plate in cooperation with the adjusting disc, so that it can better fit the human body.

[0018] 3. When driving, the adjusting component and the release component of the present invention cooperate to provide dynamic support. When resting, the servo motor drives the flat side of the adjusting disc to fit the sliding groove to eliminate the curvature of the lumbar support plate, and the stepping motor folds the support frame so that the bottom of the lumbar support plate loses support. At the same time, the first electric push rod contracts to drive the lumbar support plate to swing backward. Combined with the elastic support of the connecting spring, the lumbar support plate and the backrest are integrated into a lying plane, meeting the short-distance rest needs of the logistics vehicle. At the same time, the connecting springs on both sides of the lumbar support plate are rotatably connected to the backrest frame, providing elastic buffering during the adjustment process to avoid rigid vibration; the gear disc meshes with the gear column and cooperates with the pawl to prevent slipping, and the bevel gear transmission ensures the efficient transmission of power of the release component, ensuring the structural stability when each component cooperates.

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

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0029] As Figures 1-7 shown, a folding new energy logistics vehicle seat includes a vehicle seat. An underframe 102 is installed at the bottom of the vehicle seat. The underframe 102 is used to slide the vehicle seat for front and rear adjustment. The vehicle seat includes a backrest and a seat. The backrest and the seat can rotate relative to each other. The backrest rotation adjustment mechanism and the sliding structure of the underframe 102 of the vehicle seat both adopt existing technologies and will not be described in detail. A support skeleton is arranged inside the vehicle seat. The support skeleton includes a seat frame 101. The upper part of the rear side of the seat frame 101 is rotatably connected to a backrest frame 103. A back support plate 104 is installed on the upper part inside the backrest frame 103. An adjustment component and a release component are installed on the lower part of the front side of the back support plate 104. When a new energy logistics vehicle driver feels waist fatigue during long-distance driving, the seat adjustment function can be started through the vehicle-mounted system. The protruding curvature of the lumbar support plate 105 can be adjusted through the adjustment component to support the user's waist.

[0030] The adjustment assembly includes a lumbar support plate 105. The top of the lumbar support plate 105 is fixedly connected to the lower part of the front side of the backrest plate 104. A lumbar brace plate 107 is rotatably connected to the bottom of the backrest plate 104. Evenly distributed horizontal and vertical bars 113 are installed on the upper part of the side of the lumbar support plate 105 close to the lumbar brace plate 107. Chute 120s are provided on both sides of the middle of the horizontal and vertical bars 113. A housing 119 is fixedly connected to the middle of the rear side of the lumbar brace plate 107. A servo motor is installed inside the housing 119. The driving end of the servo motor is fixedly connected to a fixed shaft 125. A tooth column 127 is meshed and connected to one side of the front part of the fixed shaft 125. A pawl is provided on the side of the tooth column 127 away from the tooth disc 126. The pawl is installed at the rear end of the lumbar brace plate 107. A rotating rod 128 is fixedly connected to the middle of the tooth column 127. Adjusting discs 110 are fixedly connected to both ends of the outer circumference of the rotating rod 128. Partition plates 131 are fixedly connected to the inside of the adjusting discs 110. Electric push rods II 130 are fixedly connected to the middle of the wall bodies of the partition plates 131. The telescopic ends of the electric push rods II 130 are fixedly connected to push plates 129. The push plates 129 are all fitted into the middle of one side of the outer circumference of the adjusting discs 110. One side of each adjusting disc 110 is set to be in a flat state, and the other side of each adjusting disc 110 is set to be a gradually changing arc. The adjusting discs 110 are all arranged inside the chute 120s.

[0031] Furthermore, in specific implementation, first, the servo motor starts to operate, driving the fixed shaft 125 to rotate. Through the meshing transmission between the tooth disc 126 and the tooth column 127, the adjusting discs 110 at both ends of the rotating rod 128 are driven to rotate inside the chute 120s of the horizontal and vertical bars 113. The arc side of the adjusting disc 110 gradually pushes out the lumbar brace plate 107, causing the lumbar support plate 105 to bend to form an arc that conforms to the curve of the human waist. At the same time, the electric push rod I 108 can push the lumbar brace plate 107 to perform a yaw to finely adjust the position and angle between the lumbar brace plate 107 and the lumbar support plate 105, thereby greatly enhancing the support strength and comfort of the vehicle seat for the waist. At the same time, when needed, the electric push rod II 130 can push the push plate 129 to finely adjust the position of the adjusting disc 110, increase the adjustment range of the adjusting disc 110, and enhance the support strength.

[0032] Among them, the release component includes a stepping motor 109. The stepping motor 109 is installed at the lower rear side of the lumbar support plate 107. A driving end of the stepping motor 109 is fixedly connected with a driving bevel gear 123 on the outer periphery. A driven bevel gear 124 is meshed and connected to the front of the driving bevel gear 123. A rotating shaft 114 is fixedly connected to the middle of the driven bevel gear 124. The rotating shaft 114 is arranged on the front side of the lumbar support plate 107. Threaded sections 115 are provided at both ends of the outer periphery of the rotating shaft 114. Adjusting rods 116 are threadedly connected to both sides of the outer periphery of the rotating shaft 114 through the threaded sections 115. Limiting rods 122 are slidably connected to the inner walls of the adjusting rods 116. Ends of the limiting rods 122 are fixedly connected to the front wall of the lumbar support plate 107. Fixing rings 118 evenly distributed are fixedly connected to the outer peripheries of the adjusting rods 116. Connecting rods 117 are rotatably connected to the front and rear sides of the fixing rings 118. One ends of the connecting rods 117 far from the fixing rings 118 are rotatably connected to support frames 112. One ends of the support frames 112 far from the connecting rods 117 are rotatably connected to connecting rods 121. The front connecting rods 121 are all installed at the lower rear side of the lumbar support plate 105. Rear ends of the rear connecting rods 121 are all installed with connecting plates 111. The connecting plates 111 are all arranged inside the vehicle seat.

[0033] Further, in 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 stepping motor 109 can be further started. The driving bevel gear 123 can be driven to rotate by the stepping motor 109. The driving bevel gear 123 drives the driven bevel gear 124 to rotate the rotating shaft 114. The adjusting rods 116 can be driven to move outward along the limiting rods 122 through the threaded sections 115 on both sides of the rotating shaft 114. The support frames 112 can be driven to swing by the connecting rods 117. The bottom of the lumbar support plate 105 is lifted by the support frames 112 to eliminate the gap. When the driver needs to take a short rest during long-distance logistics work, the user can start the release component through the vehicle-mounted system to switch the vehicle seat to the "rest mode".

[0034] Among them, the release component further includes an electric push rod 108. The electric push rod 108 is rotatably connected to the lower rear side of the backrest support plate 104. One end of the electric push rod 108 far from the backrest support plate 104 is rotatably connected to the end of the housing 119. Connecting springs 106 are fixedly connected to the rear sides of both sides of the lumbar support plate 107. One ends of the connecting springs 106 far from the lumbar support plate 107 are rotatably connected to both sides of the front of the backrest frame 103.

[0035] Furthermore, in specific implementation, after the vehicle seat is laid flat, the servo motor drives the flat side of the adjustment disc 110 to fit the chute 120 to eliminate the curvature of the lumbar support plate 105. The stepping motor 109 drives the support frame 112 to swing and fold, causing the bottom of the lumbar support plate 105 to lose support. At the same time, the first electric push rod 108 contracts to drive 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 the structural stability and provide a comfortable rest space for the driver.

[0036] Working principle:

[0037] When the driver of a new energy logistics vehicle feels lumbar fatigue during long-distance driving, the seat adjustment function can be activated through the vehicle-mounted 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 operate, driving the fixed shaft 125 to rotate. Through the meshing transmission of the gear disc 126 and the gear column 127, the adjustment discs 110 at both ends of the rotating rod 128 rotate in the chute 120 of the horizontal straight bar 113. The arc side of the adjustment disc 110 gradually pushes out the lumbar support plate 107, causing the lumbar support plate 105 to bend into a curvature that conforms to the human lumbar curve. At the same time, the first electric push rod 108 can push the lumbar support plate 107 to swing to finely adjust the position and angle of the lumbar support plate 107 and the lumbar support plate 105, thereby greatly enhancing the support strength and comfort of the vehicle seat for the waist. At the same time, when needed, the second electric push rod 130 can push the push plate 129 to finely adjust the position of the adjustment disc 110, increase the adjustment range of the adjustment disc 110, and enhance the support strength. 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 stepping motor 109 can be further activated. The stepping motor 109 can drive the driving bevel gear 123 to rotate. The driving bevel gear 123 drives the driven bevel gear 124 to rotate the rotating shaft 114. The threaded sections 115 on both sides of the rotating shaft 114 can drive the adjusting rod 116 to move outward along the limiting rod 122. The connecting rod 117 can drive the support frame 112 to swing, and the support frame 112 jacks up the bottom of the lumbar support plate 105 to eliminate the gap. When the driver needs to take a short rest during long-distance logistics work, the user can activate the release component through the vehicle-mounted system to switch the vehicle seat to the "rest mode". After the vehicle seat is laid flat, the servo motor drives the flat side of the adjustment disc 110 to fit the chute 120 to eliminate the curvature of the lumbar support plate 105. The stepping motor 109 drives the support frame 112 to swing and fold, causing the bottom of the lumbar support plate 105 to lose support. At the same time, the first electric push rod 108 contracts to drive 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 the structural stability and provide a comfortable rest space for the driver.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present invention.
