[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0028] The leg rests and reclining mechanisms of traditional vehicle seats are extremely costly, and the welcome function is dull and uninteresting (the seat only translates and cannot change its posture), making it increasingly insufficient in meeting the growing personalized needs. At the same time, as the automotive market becomes more diverse, the demand for multi-functional seats in cars has increased sharply. Functions such as seat leg rests and seat welcome, which were previously only available on luxury models, are gradually spreading to ordinary models. However, the existing leg rest modules and reclining modules are all independent modules, requiring a large number of components, having a relatively complex structure, and a high manufacturing cost. Therefore, it is necessary to make improvements.

[0029] For example, an automotive seat leg rest mechanism and an automotive seat including the same. The automotive seat leg rest mechanism includes: a leg rest cover plate assembly slidably mounted on a leg rest cover plate bracket; one end portions of a four-bar mechanism are respectively connected to two side edges of the leg rest cover plate bracket, and one end portions of an HDM and a lead screw assembly are respectively connected to two ends of a horizontal motor assembly. The other end portions of the HDM and the lead screw assembly are fixedly attached to the other end portions of the corresponding four-bar mechanism; a lead screw motor assembly is mounted at the bottom of the leg rest cover plate bracket. A sliding member is sleeved on the lead screw of the lead screw motor assembly and passes through an opening groove on the leg rest cover plate bracket and is fixed to the bottom of the leg rest cover plate assembly. By driving the sliding member to move through the lead screw motor assembly, the leg rest cover plate assembly is driven to extend and retract along the leg rest cover plate bracket.

[0030] Although the above automotive seat leg rest mechanism uses two sets of independent mechanisms to achieve the flipping and telescoping functions of the leg rest, and uses a four-bar mechanism to replace fixed-axis rotation to achieve a larger rotation angle, the above automotive seat leg rest mechanism is an independent module, requiring a large number of components during production and manufacturing, and having a high manufacturing cost, resulting in a relatively low versatility of the above automotive seat leg rest mechanism. Therefore, it is necessary to make improvements.

[0031] Another example is that an automotive seat lifting mechanism includes two sets of link assemblies arranged opposite to each other. A synchronous drive rod is connected between the two sets of link assemblies. A drive handle is provided on the synchronous drive rod, and the drive handle is connected to a power device; the link assembly includes an upper link and a lower link. The lower end of the upper link is fixedly sleeved on the synchronous drive rod, and the upper end of the lower link is movably sleeved on the synchronous drive rod; the power device includes a lead screw motor. The housing of the lead screw motor is hinged to a support through an ear, the lead screw of the lead screw motor is hinged to the drive handle, and the support is fixed on the seat frame.

[0032] In the above automotive seat lifting mechanism, when the lead screw of the lead screw motor extends and retracts, it pushes and pulls the drive handle, causing the synchronous drive rod to swing. The upper links fixedly connected to both ends of the synchronous drive rod rotate, and the lower links hinged to the upper links also rotate. The change in the angle between the upper and lower links causes a change in the overall height of the upper and lower links, thereby achieving the purpose of lifting the automotive seat.

[0033] The above-mentioned vehicle seat lifting mechanism also has a relatively complex structure, requires a large number of components during production and manufacturing, and has a high manufacturing cost. As a result, the versatility of the above-mentioned vehicle seat leg rest mechanism is relatively low. Therefore, it is necessary to make improvements.

[0034] The embodiment of the present application provides a vehicle seat structure, which can solve the problems of a large number of components and high costs required by the leg rest module and the forward tilt module in the related art, so that the vehicle seat can be mutually transformed between the welcome mode, the leg rest deployment mode, and the forward tilt mode. It can not only meet people's personalized needs, but also the vehicle seat of the present invention has high structural stability, requires fewer components, and has a lower manufacturing cost.

[0035] As Figure 1 shown, the vehicle seat structure of the present invention includes: a seat assembly 1, a leg rest bracket 5, and a lower slide rail 2; wherein, one end of the leg rest bracket 5 is rotatably connected to the front end of the seat assembly 1, and the leg rest bracket 5 is configured to slide along the lower slide rail 2 through its other end, so that the inclination angle of the seat surface 13 of the seat assembly 1 relative to the plane where the lower slide rail is located is changed.

[0036] For example, the seat surface can be a flat surface or a curved surface. When the seat surface is a curved surface, the inclination angle of the seat surface relative to the plane where the lower slide rail is located can be the inclination angle of the tangent plane at any point on the seat surface and the plane where the lower slide rail is located.

[0037] In the above technical solution, the seat surface 13 is arranged on the cushion assembly 12. When the other end (the end far from the seat assembly 1) of the leg rest bracket 5 slides along the lower slide rail 2, one end (the end connected to the seat assembly 1) of the leg rest bracket 5 will swing up and down in the vertical plane, so that the inclination angle α of the seat surface 13 relative to the plane where the lower slide rail is located is changed. As Figures 1 to 4 shown, in this way, the present invention can make the vehicle seat mutually transform between the normal mode ( Figure 1 ), the welcome mode ( Figure 2 ), the leg rest deployment mode ( Figure 3 ), and the forward tilt mode ( Figure 4 ). It can not only meet people's personalized needs, but also the structure of the present invention has high stability, requires fewer components, and has a lower manufacturing cost.

[0038] The present invention further includes a first slide rail assembly 4. The other end of the leg rest bracket 5 is rotatably connected to the first slide rail assembly 4, and the first slide rail assembly 4 is configured to slide along the lower slide rail, so as to drive the leg rest bracket 5 to slide along the lower slide rail. In this way, under the action of the first slide rail assembly 4, the leg rest bracket 5 can change the inclination angle of the seat surface 13 of the seat assembly 1 relative to the plane where the lower slide rail is located.

[0039] During actual operation, the upper end of the first slide rail assembly 4 is rotatably connected to one end of the leg bracket 5, and the front end of the seat assembly 1 is rotatably connected to the other end of the leg bracket 5. The lower end of the first slide rail assembly 4 is slidably disposed on the lower slide rail 2.

[0040] Preferably, a power driving component (such as the first driving mechanism 6) is connected to the first slide rail assembly 4. The first driving mechanism 6 is connected to the lower slide rail 2 to drive the first slide rail assembly 4 to slide on the lower slide rail 2.

[0041] In the above technical solution, the above-mentioned rotatable connection can be a hinge connection. The seat assembly 1 includes a seat cushion assembly 12 and a backrest assembly 11. The seat cushion assembly 12 is for the driver to sit on, and the backrest assembly 11 is for the driver to rely on when sitting. The first driving mechanism 6 is mainly used to drive the first slide rail assembly 4 to slide (slide back and forth) on the lower slide rail 2, and the second driving mechanism 9 is also mainly used to drive the first slide rail assembly 4 to slide (slide back and forth) on the lower slide rail 2. The lower slide rail 2 is for the first slide rail assembly 4 and the second slide rail assembly 7 to slide back and forth, so as to drive the seat assembly 1 to slide back and forth, and further realize the adjustment of the position of the seat assembly 1.

[0042] The present invention can enable the vehicle seat to be converted between a normal mode, a welcome mode, a leg rest deployment mode, and a forward tilt mode, which can not only meet people's personalized needs, but also has high structural stability, fewer required components, and lower manufacturing costs for the vehicle seat of the present invention.

[0043] The leg bracket 5 includes: a bracket seat 51, and the bracket seat 51 is installed at the front end of the seat assembly 1; a swing seat 52, one end of the swing seat 52 is hinged to the first slide rail assembly 4, and the other end is hinged to the bracket seat 51. In this way, one end of the leg bracket 5 can be hinged to the first slide rail assembly 4, and the other end can be hinged to the seat assembly 1. When the first slide rail assembly 4 slides on the lower slide rail 2, the leg bracket 5 can be in an extended or retracted state. In this way, the present invention realizes the arrangement of the leg rest deployment mode.

[0044] The bracket seat 51 includes: a first support 53, and the first support 53 is installed at the front end of the seat assembly 1; at least two first hinge plates 54, one end of the first hinge plates 54 is installed on the first support 53, and the other end is provided with a first hinge hole for cooperating with the swing seat 52. In this way, a bolt or a rotating pin can be inserted into the first hinge hole, and the leg bracket 5 can be hinged to the seat assembly 1 through the above-mentioned bracket seat 51.

[0045] The swing seat 52 includes: a swing plate 55, there are at least two swing plates 55 which respectively correspond to the positions of the first hinge plate 54, one end of the swing plate 55 is hinged to the first hinge plate 54, and the other end is hinged to the first slide rail assembly 4; a connecting rod 56, and a plurality of connecting rods 56 are connected between the two swing plates 55. Bolts or rotating pins can be inserted at both ends of the swing seat 52. In this way, the leg bracket 5 can be rotatably connected to the seat assembly 1 and the first slide rail assembly 4 respectively through the swing seat 52.

[0046] The first slide rail assembly 4 includes: a first slide rail 41, there are at least two first slide rails 41 which are respectively arranged on the two lower slide rails 2, and the first slide rail 41 is hinged to the leg bracket 5 through a first connecting member 43; a first slide rail seat 41, the first slide rail seat 41 is installed between the two first slide rails 41, and the first driving mechanism 6 is installed on the first slide rail seat 41.

[0047] During actual work, the first slide rail assembly 4 can also be called the front upper slide rail assembly. The first slide rail 41 is sleeved on the lower slide rail 2 and can slide on the lower slide rail 2. When the first driving mechanism 6 works, it drives the first slide rail seat 41 to slide along the parallel direction of the lower slide rail 2, so as to drive the first slide rail 41 to slide on the lower slide rail 2 through the first slide rail seat 41. In this way, the layout of the first slide rail assembly 4 is realized in the present invention.

[0048] During actual work, the first connecting member 43 includes: a first connecting plate, the first connecting plate is installed on the first slide rail 41, and a first hinge hole for mating connection with the seat assembly 1 or the leg bracket 5 is provided on the first connecting plate.

[0049] In the above technical solution, the first connecting plate is integrally in a plate-like structure, and the length of the first connecting plate is very long. As long as the above first connecting plate has sufficient structural strength to enable the rotatable connection between the first slide rail assembly 4 and the seat assembly 1.

[0050] The first driving mechanism 6 includes: a first driving motor 61, the first driving motor is installed on the first slide rail seat 41, and the output end of the first driving motor is connected with a first driving shaft 63; a first gear box 62, the input end of the first gear box 62 is connected with the first driving shaft 63, and the output end of the first gear box 62 is connected with the lead screw 3.

[0051] In the above technical solution, the first gear box 62 can be arranged on the first slide rail 41, so that the structure of the first slide rail assembly 4 is more compact and occupies less space of the seat assembly 1.

[0052] Preferably, there are two first drive shafts 63. Both ends of the drive motor are connected to the first drive shafts 63, and each first drive shaft 63 is connected to a first gearbox 62 disposed on the first slide rail 41. In this way, the structural stability of the present invention at the first slide rail assembly 4 is higher, and the first drive mechanism 6 can drive the first slide rail 41 to slide on the lower slide rail 2 more stably and efficiently, thereby making the structural stability of the present invention higher.

[0053] Furthermore, the two first drive shafts 63 can be a short flexible shaft and a long flexible shaft respectively. A sleeve is provided on the long flexible shaft, and clamping plates are provided at both ends of the sleeve and arranged on the first slide rail seat 41. In this way, the present invention can not only more conveniently install the two first drive shafts 63 on the first slide rail seat 41, but also has higher structural stability of the first slide rail assembly 4.

[0054] During actual operation, the present invention further includes a second slide rail assembly 7. The upper end of the second slide rail assembly 7 is rotatably connected to the rear end of the seat assembly 1, and the lower end of the second slide rail assembly 7 is slidably arranged on the lower slide rail 2; a second drive mechanism 9, the second drive mechanism 9 is connected to the lower slide rail 2 to drive the second slide rail assembly 7 to slide on the lower slide rail 2. In this way, the present invention can not only make the vehicle seat convertible between the welcome mode, the leg rest deployment mode and the forward tilt mode, but also can integrally move the position of the seat assembly 1, thereby making the present invention more convenient to use.

[0055] The upper end of the second slide rail assembly 7 is hinged to the rear end of the seat assembly 1 through a cross tube assembly 8. The cross tube assembly 8 includes: a rear cross tube 81, both ends of the rear cross tube 81 are hinged to the seat assembly 1, and the middle part of the rear cross tube 81 is fixedly connected to the second slide rail assembly 7. In this way, the present invention realizes the arrangement of the cross tube assembly 8, and the upper end of the second slide rail assembly 7 can be rotatably connected to the rear end of the seat assembly 1 through the cross tube assembly 8. Preferably, limiting rotating shaft sleeves 82 can be sleeved at both ends of the rear cross tube 81, and the limiting rotating shaft sleeves 82 are installed on the seat cushion assembly 12. In this way, the structural stability of the cross tube assembly 8 is higher.

[0056] During actual operation, when the first slide rail assembly 4 and / or the second slide rail assembly 7 are in different positions on the lower slide rail 2, the leg support 5 correspondingly enables the vehicle seat to be convertible between the welcome mode, the leg rest deployment mode and the forward tilt mode: when the distance between the first slide rail assembly 4 and the second slide rail assembly 7 is relatively close, the leg support 5 is in a retracted state at this time, and the vehicle seat is in the welcome mode; when the distance between the first slide rail assembly 4 and the second slide rail assembly 7 is moderate, the leg support 5 is in an upright state at this time, and the vehicle seat is in the forward tilt mode; when the distance between the first slide rail assembly 4 and the second slide rail assembly 7 is relatively far, the leg support 5 is in a deployed state at this time, and the vehicle seat is in the leg rest deployment mode.

When the second driving mechanism 9 works, it drives the second slide rail seat 72 to slide along the parallel direction of the lower slide rail 2, so as to drive the second slide rail 71 to slide on the lower slide rail 2 through the second slide rail seat 72. In this way, the present invention realizes the layout of the second slide rail assembly 7.

[0059] During actual work, the second connecting member 74 includes: a second connecting plate, the second connecting plate is installed on the second slide rail 71, and a top support groove matching the rear cross tube 81 is provided on the second connecting plate. The top support groove is semicircular and is used to place the rear cross tube 81. In this way, the second slide rail assembly 7 realizes the connection with the cross tube assembly 8 through the above second connecting plate.

[0060] Preferably, the second connecting member may include strengthening members at the front and rear ends of the second slide rail 71 and a support member between the two strengthening members. The strengthening members and the support member are both plate-shaped structures, and the strengthening members and the support member are vertically connected to each other.

[0063] Preferably, there are two second driving shafts 93. Both ends of the driving motor are connected to the second driving shafts 93, and each second driving shaft 93 is connected to a second gearbox 92 arranged on the second slide rail 71. In this way, the structural stability of the present invention at the second slide rail assembly 7 is higher, and the second driving mechanism 9 can drive the second slide rail 71 to slide on the lower slide rail 2 more stably and efficiently, so that the structural stability of the present invention is higher.

[0064] Further, the two second drive shafts 93 can be a short flexible shaft and a long flexible shaft respectively. A sleeve is provided on the long flexible shaft, and clamping plates arranged on the second slide rail seat 72 are provided at both ends of the sleeve. In this way, the present invention can not only more conveniently install the two second drive shafts 93 on the second slide rail seat 72, but also the structural stability of the second slide rail assembly 7 is higher.

[0065] During actual work, in order to further strengthen the structural strength of the first slide rail assembly 4 and / or the second slide rail assembly 7, reinforcing ribs can be provided on the first slide rail seat 41 and / or the second slide rail seat 72, so as to improve the structural strength of the present invention.
