Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat with a lying-flat function. Background Art

[0002] Cars are a common means of transportation. With the rapid development of automobile technology, new energy vehicles are also developing very rapidly. Car seats are important parts in car use. According to the shape, they can be divided into split seats and long seats; according to the function, they can be divided into fixed, removable, and adjustable types; according to the number of passengers, they can be divided into single, double, and multi-person seats. According to the performance of the seat, from the earliest fixed seats, it has developed to multi-functional power adjustment seats, including air cushion seats, electric seats, stereo seats, spirit recovery seats, and electronic adjustment seats. According to the material, it can be divided into leather seats and velvet seats. There are also some seats for special users, such as child seats and racing seats.

[0003] The seats arranged in a row behind the driver's seat have a function where the backrest and cushion can be folded through a mechanical structure. This is generally done to connect the passenger compartment and the trunk to obtain a larger cargo space. Contemporary cars are generally composed of an engine compartment, a passenger compartment, and a trunk luggage compartment. The backrest of the rear seat is the partition between the passenger compartment and the trunk. This partition is opened by folding the seat back forward to fit the seat cushion, completing the connection between the passenger compartment and the trunk, thereby expanding the usable space of the trunk and enabling the trunk to carry larger or more objects. The rear seats generally have storage requirements, and the backrests often need to be laid forward to increase the storage space in the car. However, the rotation center of the backrest of this structure is often relatively high, and the backrest with the rotation center high will have a back-up phenomenon during the process of lying backward, resulting in poor comfort. Utility Model Content

[0004] The purpose of the utility model is to provide a seat with a lying-flat function, aiming to optimize the seat adjustment structure, lift the seat cushion when the backrest is lying backward, so as to cause the rotation center of the backrest to drop relatively, solve the problem of the backrest, and at the same time let the top point drop to support the waist and improve comfort.

[0005] To achieve the above-mentioned purpose, the utility model provides a seat with a lying-flat function, including a cushion device and an auxiliary device;

[0006] The auxiliary device includes a backrest assembly, a rear mounting bracket, a driving gear, a driven gear and a driving assembly. The backrest assembly is arranged on one side of the cushion device, and the rear mounting bracket is arranged on both sides of the cushion device. The driving gear is located on one side of the backrest assembly. The driven gear is rotatably connected to the rear mounting bracket and the cushion device respectively, and is meshed with the driving gear and is located on one side of the rear mounting bracket. The driving assembly is arranged on one side of the backrest assembly.

[0007] Wherein, the auxiliary device also includes a front mounting bracket, which is detachably connected to the seat cushion device and is located on both sides in front of the seat cushion device.

[0008] Wherein, the driving assembly includes an adjusting motor and a spline shaft, the adjusting motor is fixedly connected to the backrest assembly and is located on the side of the backrest assembly close to the driving gear; the spline shaft cooperates with the adjusting motor and the driving gear respectively and is located on one side of the driving gear.

[0009] Wherein, a steel wire mesh is arranged on the seat cushion device.

[0010] Wherein, a headrest component is arranged on the backrest assembly.

[0011] The utility model provides a seat with a lying flat function, wherein the driving gear has a partial notch. When the backrest is adjusted forward, the notch corresponds to the driven gear, so that the backrest can be smoothly laid flat forward, thereby not driving the seat cushion. When the backrest is adjusted backward, the non-notch portion of the driving gear meshes with the driven gear. Driven by the driven gear, the seat cushion can be lifted around the front rotation point, and the seat cushion device and the driven gear can also slide relatively along the notch of the driven gear. Through the above movement, when the backrest is adjusted backward, the seat cushion is lifted, thereby achieving a lying flat posture. The driving component realizes the rotation of the driving gear, thereby realizing the optimization of the seat adjustment structure. The seat cushion is lifted during the process of the backrest lying backward to cause the rotation center of the backrest to relatively descend, thereby solving the problem of the backrest, and at the same time allowing the top point to descend so that the waist is supported, thereby improving comfort.

[0022] The backrest assembly 102 is arranged on one side of the cushion device 101, the rear mounting bracket 103 is arranged on both sides of the cushion device 101, the driving gear 104 is located on one side of the backrest assembly 102, the driven gear 105 is rotatably connected with the rear mounting bracket 103 and the cushion device 101 respectively, and meshes with the driving gear 104, and is located on one side of the rear mounting bracket 103, and the driving assembly is arranged on one side of the backrest assembly 102. The backrest assembly 102 is used for cushion setting, the rear mounting bracket 103 can be fixed to the frame by bolts, the driving gear 104 has a partial notch, when the backrest is adjusted forward, the notch corresponds to the driven gear 105, so that the backrest can be smoothly laid forward, so as not to drive the cushion, when the backrest is adjusted backward, the non-notch part of the driving gear 104 meshes with the driven gear 105, driven by the driven gear 105, the cushion can be lifted around the front rotation point, and the cushion device 102 is provided with a plurality of driving gears 104, and the driving gear 105 is provided with a plurality of driving gears 105, and the driving gear 105 ...5, and the driving gear 105 is provided with a plurality of driving gears 105, and the driving gear 10 01 and the driven gear 105 will also slide relatively along the groove of the driven gear 105. Through the above movement, the seat cushion can be lifted when the backrest is adjusted backward, so as to achieve a lying posture. The driven gear 105 is provided with an inclined slide groove, which slides with the seat cushion device 101 through a sliding pin and realizes rotation. The driven gear 105 is also riveted to the rear mounting bracket 103. The driving assembly is arranged on one side of the backrest assembly 102, and is used to drive the driving gear 104 to rotate.

[0023] Secondly, the front mounting bracket 106 is detachably connected to the seat cushion device 101 and is located on both sides in front of the seat cushion device 101. The front mounting bracket 106 is riveted to the front side of the seat cushion device 101, symmetrically arranged, and can be fixed to the vehicle frame by bolts.
