Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a seat and a vehicle. Background Art

[0002] Cars are one of the important means of transportation. Due to their convenience, high speed and flexible transportation capabilities, they are widely used in diverse scenarios such as urban commuting, long-distance travel and cargo transportation.

[0003] Seats are an important part of a car, providing comfortable support for the driver and passengers and protecting the safety of the occupants in an emergency. In the event of a collision, seats can help disperse the impact force and keep passengers in a preset safety zone.

[0004] For vehicles with multiple rows of seats, due to the limited space in the cabin, in some cases, passengers sitting in the back row need to adjust the front row seats first before they can get in and out. However, the existing seat position adjustment operation is complicated, which is not convenient for the back row passengers to get in and out quickly. Utility Model Content

[0005] The embodiments of the utility model provide a seat and a vehicle, which are used to solve the problem of complicated operation when adjusting the position of the existing seat.

[0006] In order to achieve the above object, the embodiment of the utility model adopts the following technical solution:

[0007] On the one hand, an embodiment of the present application provides a seat, which includes a mounting assembly, a seat cushion frame, a backrest frame, a driving member, a first locking mechanism, a second locking mechanism, a linkage assembly and a first pulling member. The seat cushion frame is rotatably connected to the mounting assembly. The backrest frame is rotatably connected to the seat cushion frame. The driving member is mounted on the backrest frame and is used to rotate with the backrest frame relative to the seat cushion frame. The first locking mechanism is used to put the seat cushion frame and the mounting assembly in a locked state or an unlocked state. The second locking mechanism is used to put the seat cushion frame and the backrest frame in a locked state or an unlocked state. The linkage assembly is movably linked to the seat cushion frame and connected to the first locking mechanism. The first pulling member is connected to the linkage assembly and connected to the second locking mechanism. The first pulling member is used to unlock the second locking mechanism and is also used to pull the linkage assembly so that the driving member abuts against the linkage assembly during rotation, driving the linkage assembly to move so as to unlock the first locking mechanism.

[0008] The seat provided in the embodiment of the present application can unlock the second locking mechanism by pulling the first pulling member, so that the backrest frame and the seat cushion frame are in an unlocked state, and the backrest frame can rotate relative to the seat cushion frame. During the rotation of the backrest frame relative to the seat cushion frame, the driving member rotates with the backrest frame relative to the seat cushion frame. Pulling the first pulling member can also cause the driving member to come into contact with the linkage assembly during the rotation process, driving the linkage assembly to move, thereby unlocking the first locking mechanism. Unlocking the first locking mechanism causes the seat cushion frame and the mounting assembly to be in an unlocked state, and the seat cushion frame can rotate relative to the mounting assembly.

[0009] Thus, the seat provided in the embodiment of the present application can realize the rotation of the backrest frame relative to the seat cushion frame, and the rotation of the seat cushion frame relative to the mounting assembly by pulling the first pulling member. When adjusting the seat, the user only needs to pull the first pulling member to realize the angle adjustment between the backrest frame, the seat cushion frame and the mounting assembly, thereby simplifying the operation steps, reducing the time required for unlocking and adjusting respectively, improving the convenience of user use and the efficiency of adjustment, and thus facilitating the rapid entry and exit of passengers. In some embodiments, the linkage assembly includes a first linkage member and a second linkage member. The first linkage member is rotatably connected to the seat cushion frame.

Among them, the first pulling member is connected to the second linkage member, and is used to drive the second linkage member to slide relative to the first linkage member, so that the driving member abuts and contacts during the rotation process, and then drives the first linkage member to rotate, so that the first locking mechanism is unlocked.

[0010] In some embodiments, the first linkage member is formed with a first sliding groove. The second linkage member includes an abutting portion and a connecting portion connected to each other. The abutting portion is slidably connected in the first sliding groove, and the connecting portion is connected to the first pulling member.

[0011] In some embodiments, the seat cushion frame has two seat cushion side walls arranged opposite to each other, and the seat cushion side walls are formed with a second sliding groove. The driving member is located on one side of the seat cushion side wall, and the linkage assembly is located on the side of the seat cushion side wall away from the driving member. The abutment portion is inserted into the second sliding groove.

[0012] In some embodiments, during the movement of the driving member against the abutting portion, the angle between the tangential direction of the rotation of the driving member and the tangential direction of the rotation of the abutting portion is less than or equal to 45°.

[0013] In some embodiments, the seat further comprises a second pulling member, a third pulling member and a transmission member. One end of the second pulling member is connected to the linkage assembly. One end of the third pulling member is connected to the first locking mechanism. The transmission member is rotatably connected to the cushion frame. The other end of the second pulling member and the other end of the third pulling member are respectively connected to the two ends of the transmission member. The distance between the other end of the second pulling member and the rotation axis of the transmission member is smaller than the distance between the other end of the third pulling member and the rotation axis of the transmission member.

[0014] In some embodiments, the mounting assembly includes a first slide rail and a second slide rail. The second slide rail is slidably connected to the first slide rail. The seat cushion frame is rotationally connected to the second slide rail, and the rotation axis of the seat cushion frame is perpendicular to the sliding direction of the second slide rail. The seat cushion frame has a normal state and an inclined state relative to the second slide rail. The seat also includes a limit assembly and a retaining mechanism. The limit assembly is connected to the first slide rail. The retaining mechanism is connected to the seat cushion frame and the second slide rail. Among them, the retaining mechanism is used to keep the seat cushion frame in an inclined state. And during the movement relative to the first slide rail, the retaining mechanism is also used to contact the limit assembly to restore the seat cushion frame to a normal state.

[0015] In some embodiments, the holding mechanism includes a holding component and a return component. The holding component is movably connected to the seat cushion frame and the second slide rail, and is used to move synchronously with the rotation of the seat cushion frame. The holding component has a first limit portion. The return component is movably connected to the second slide rail, and the sliding component has a second limit portion. Wherein, when the seat cushion frame is in a tilted state and moves relative to the first slide rail, the return component contacts and moves relative to the limit component, and the second limit portion abuts against the first limit portion, driving the holding component to move, so that the seat cushion frame returns to a normal state.

[0016] In some embodiments, the retaining assembly includes a first retaining member, a second retaining member and a third retaining member. One end of the first retaining member is connected to the seat cushion frame, and the other end is rotatably connected to the second slide rail, and the rotation axis is parallel to the rotation axis of the seat cushion frame.

DETAILED DESCRIPTION

[0040] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0041] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0042] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0045] The embodiment of the present application provides a vehicle, which may include an engine, a chassis, and a body. It is understandable that the vehicle may be a fuel vehicle, an electric vehicle, a hybrid vehicle, a gas vehicle, a methanol vehicle, a solar vehicle, etc., and the type of vehicle is not specifically limited here.

[0046] Among them, the engine is the power unit of the car, which can provide power for the vehicle to move on the ground.

[0047] The chassis can be used to install the engine and other vehicle components to form the overall shape of the vehicle, and receive power from the engine to make the vehicle move and ensure normal driving.

[0048] The vehicle body can be installed on the chassis, and a cabin is formed inside the vehicle body, which can accommodate drivers, passengers and cargo.

[0049] The vehicle provided in the embodiment of the present application may also include a seat, which is arranged inside the vehicle cabin and can provide comfortable support for the driver and passengers and protect the safety of the passengers in an emergency. When a collision occurs, the seat can help disperse the impact force and keep the passengers in a preset safe area.

[0050] In vehicles with multiple rows of seats such as Multi-Purpose Vehicles (MPV) or Sport Utility Vehicles (SUV), due to the limitation of cabin space, in some cases, such as when encountering an emergency and needing to escape, rear passengers need to first adjust the seats of the second row passengers to make room before they can get out.

[0051] Therefore, car seats are generally designed with an Easy Entry (EZE) function, which refers to the convenient entry function of the front seats, which allows the front seats to tilt forward or slide significantly through simple operations, so that rear passengers can enter and exit the vehicle more easily.

[0052] In the related art, a seat includes a mounting assembly, a seat cushion frame and a backrest frame. The seat cushion frame is rotatably connected to the mounting assembly, and the backrest frame is rotatably connected to the seat cushion frame. The seat cushion frame and the mounting assembly, and the backrest frame and the seat cushion frame can be in a locked state or an unlocked state to achieve adjustment and fixation between the above components.

[0053] When adjusting the seat, the user can first adjust the backrest frame relative to the seat cushion frame, and then adjust the seat cushion frame relative to the mounting assembly. However, adjusting the backrest frame and the seat cushion frame separately is complicated, and the user needs a long time to adjust the seat.

[0054] Based on this, the embodiment of the present application provides a seat, such as Figure 1 As shown, Figure 1 The present invention provides a structural schematic diagram of a seat 100 provided in an embodiment of the present invention. The seat 100 may include a mounting assembly 1, a seat cushion frame 2, and a backrest frame 3. The mounting assembly 1 may be installed in a vehicle cabin to stably and safely mount the seat 100 on the vehicle. It is understood that the mounting position of the mounting assembly 1 in the vehicle cabin may be set as required.

[0055] The backrest frame 3 provides support for the back of the driver and passenger, and improves the stability of the seat 100 under load conditions. The backrest frame 3 and the seat cushion frame 2 form the core framework of the seat 100.

[0056] The backrest frame 3 can be rotatably connected to the seat cushion frame 2. In this way, the passenger can adjust the angle of the backrest frame 3 according to personal needs and driving conditions. The rotatable backrest frame 3 can also improve the adaptability of the interior space of the vehicle, increase the utilization rate of the interior space of the vehicle, and facilitate the passengers to enter and exit the vehicle and sit down smoothly.

[0057] The seat cushion frame 2 is rotatably connected to the mounting assembly 1. In this way, the seat cushion frame 2 can rotate relative to the mounting assembly 1, thereby improving the utilization of the space in the vehicle and facilitating the cleaning and maintenance of the seat cushion frame 2. In an emergency, if a quick evacuation from the vehicle is required, the rotatable seat cushion frame 2 design helps to speed up the evacuation.

[0058] In order to make the seat cushion frame 2 and the mounting assembly 1 in a relatively locked and unlocked state, as shown in FIG. Figure 1 As shown, the seat 100 may further include a first locking mechanism 4. The first locking mechanism 4 is used to place the seat cushion frame 2 and the mounting assembly 1 in a locked state or an unlocked state.

[0059] It is understandable that when the seat cushion frame 2 and the mounting assembly 1 are in a locked state, the seat cushion frame 2 and the mounting assembly 1 are relatively fixed, and the seat cushion frame 2 cannot rotate relative to the mounting assembly 1. When the seat cushion frame 2 and the mounting assembly 1 are in an unlocked state, the seat cushion frame 2 can rotate relative to the mounting assembly 1.

[0060] Similarly, in order to enable the backrest frame 3 and the seat cushion frame 2 to be in a relatively locked or unlocked state, the seat 100 may further include a second locking mechanism 5. The second locking mechanism 5 is used to enable the backrest frame 3 and the seat cushion frame 2 to be in a locked state or an unlocked state.

[0061] Likewise, it can be understood that when the backrest frame 3 and the seat cushion frame 2 are in a locked state, the backrest frame 3 and the seat cushion frame 2 are relatively fixed, and the backrest frame 3 cannot rotate relative to the seat cushion frame 2. When the backrest frame 3 and the seat cushion frame 2 are in an unlocked state, the backrest frame 3 can rotate relative to the seat cushion frame 2.

[0062] When the first locking mechanism 4 and the second locking mechanism 5 are in the unlocked state, as shown in FIG. Figure 2 and Figure 3 As shown, Figure 2 is a schematic diagram of the structure of the seat 100 when it is in a normal state, Figure 3 The structure diagram of the seat 100 when the seat 100 is in a forward tilted state as a whole. The seat 100 can be Figure 2 The state shown changes to Figure 3 The status shown makes it convenient for rear passengers to enter and exit.

[0063] In order to facilitate the adjustment of the seat 100, Figure 4 As shown, Figure 4 This is one of the partial enlarged views of a seat 100 provided in an embodiment of the present application, and the seat 100 may further include a driving member 6, a linkage assembly 7, and a first pulling member 8. The driving member 6 is mounted on the backrest frame 3, and the driving member 6 is used to rotate with the backrest frame 3 relative to the seat cushion frame 2.

[0064] The linkage assembly 7 is movably connected to the seat cushion frame 2 and is connected to the first locking mechanism 4 ( Figure 1 The first locking mechanism 4 can be unlocked by the movement of the linkage assembly 7, so that the seat cushion frame 2 and the mounting assembly 1 are in an unlocked state, and the seat cushion frame 2 can rotate relative to the seat cushion frame 2.

[0065] The first pulling member 8 is connected to the linkage assembly 7 and to the second locking mechanism 5. The first pulling member 8 can unlock the second locking mechanism 5. The first pulling member 8 is also used to pull the linkage assembly 7, so that the driving member 6 abuts against the linkage assembly 7 during the rotation process, driving the linkage assembly 7 to move, so that the first locking mechanism 4 is unlocked.

[0066] The seat 100 provided in the embodiment of the present application can unlock the second locking mechanism 5 by pulling the first pulling member 8, so that the backrest frame 3 and the seat cushion frame 2 are in an unlocked state, and the backrest frame 3 can rotate relative to the seat cushion frame 2. During the rotation of the backrest frame 3 relative to the seat cushion frame 2, the driving member 6 rotates with the backrest frame 3 relative to the seat cushion frame 2. Pulling the first pulling member 8 can also make the driving member 6 abut against the linkage assembly 7 during the rotation process, driving the linkage assembly 7 to move, thereby unlocking the first locking mechanism 4. The unlocking of the first locking mechanism 4 puts the seat cushion frame 2 and the mounting assembly 1 in an unlocked state, and the seat cushion frame 2 can rotate relative to the mounting assembly 1.

[0067] Therefore, the seat 100 provided in the embodiment of the present application can realize the rotation of the backrest frame 3 relative to the seat cushion frame 2, and the rotation of the seat cushion frame 2 relative to the mounting assembly 1 by pulling the first pulling member 8. When adjusting the seat 100, the user only needs to pull the first pulling member 8 to realize the angle adjustment between the backrest frame 3, the seat cushion frame 2 and the mounting assembly 1, thereby realizing a better EZE function, simplifying the operation steps, reducing the time required for unlocking and adjusting respectively, improving the convenience of user use and the efficiency of adjustment, and thus facilitating passengers to quickly enter and exit.

[0068] In some embodiments, Figure 5 As shown, Figure 5 The second partial enlarged view of a seat 100 provided in an embodiment of the present application, the linkage assembly 7 includes a first linkage member 71 and a second linkage member 72. The first linkage member 71 is rotatably connected to the seat cushion frame 2. Thus, the first linkage member 71 can rotate relative to the seat cushion frame 2. Exemplarily, the rotation axis of the first linkage member 71 is parallel to the rotation axis of the driving member 6.

[0069] The first linkage member 71 is also connected to the first locking mechanism 4 ( Figure 1 Thus, the first locking mechanism 4 can be driven to move by the rotation of the first linkage member 71, thereby unlocking the first locking mechanism 4.

[0070] The second linkage member 72 is slidably connected to the first linkage member 71. The first pulling member 8 is connected to the second linkage member 72, and is used to drive the second linkage member 72 to slide relative to the first linkage member 71, so that the driving member 6 abuts against the second linkage member 72 during the rotation process, thereby driving the first linkage member 71 to rotate, so that the first locking mechanism 4 is unlocked.

[0071] Thus, the user can drive the second linkage member 72 to slide relative to the first linkage member 71 through the first pulling member 8. When the backrest frame 3 rotates relative to the seat cushion frame 2, the driving member 6 rotates with the backrest frame 3, and the driving member 6 can abut against the second linkage member 72, so that the first linkage member 71 rotates, thereby unlocking the first locking mechanism 4.

[0072] Of course, the linkage component 7 may also be other components and connection methods, as long as the linkage can be achieved. This application does not limit this and can be selected according to specific circumstances.

[0073] For example, the first linkage member 71 in the linkage assembly 7 is slidably connected to the seat cushion frame 2 , and the first linkage member 71 is connected to the first locking mechanism 4 . The second linkage member 72 is slidably connected to the first linkage member 71 .

[0074] The first pulling member 8 is connected to the second linkage member 72, and is used to drive the second linkage member 72 to slide relative to the first linkage member 71, so that the driving member 6 abuts against the second linkage member 72 during rotation, thereby driving the first linkage member 71 to slide, so as to unlock the first locking mechanism 4.

[0075] In order to achieve the sliding connection between the first linkage member 71 and the second linkage member 72, in some embodiments, as Figure 6 As shown, Figure 6 The third partial enlarged view of a seat 100 provided in an embodiment of the present application, the first linkage member 71 is formed with a first sliding groove 711. The second linkage member 72 includes an abutting portion 721 and a connecting portion 722 connected to each other. The abutting portion 721 is slidably connected in the first sliding groove 711, and the connecting portion 722 is connected to the first pulling member 8.

[0076] like Figure 7 As shown, Figure 7 3 is a structural diagram of the abutting portion 721 being in an initial position. When the abutting portion 721 is in the initial position, the driving member 6 will not abut against the abutting portion 721 during the rotation process.

[0077] like Figure 8 As shown, Figure 8It is a structural schematic diagram showing that the abutting portion 721 is in a position where it can abut against the driving member 6. By pulling the first pulling member 8, the abutting portion 721 is driven to slide in the first sliding groove 711, and the abutting portion 721 slides to a position where it can abut against the driving member 6.

[0078] like Fig. 9 As shown, Fig. 9 6 drives the abutting portion 721 to move. The driving member 6 rotates to drive the abutting portion 721 to move, thereby driving the first linkage member 71 to rotate, so that the first locking mechanism 4 ( Figure 1 ) to unlock it.

[0079] The first sliding groove 711 is provided to constrain and guide the abutting portion 721, and the first sliding groove 711 provides a running track for the movement of the abutting portion 721, so as to ensure that the abutting portion 721 moves stably and accurately on the path preset by the first sliding groove 711. The risk of component displacement and misalignment due to accidents is reduced, and the stability of the overall structure of the seat 100 is enhanced.

[0080] By sliding the abutment portion 721 in the first sliding groove 711 , the abutment portion 721 can move relatively smoothly. The sliding design can effectively disperse the contact stress and reduce the direct contact and wear between the abutment portion 721 and the first sliding groove 711 .

[0081] For example, Figure 6 As shown, the first sliding groove 711 is along Figure 6 The first pulling member 8 can pull the abutting portion 721 to slide in the first sliding groove 711 along the up-down direction.

[0082] In addition, illustratively, when the abutting portion 721 slides to the top of the first sliding groove 711, the driving member 6 can abut against the abutting portion 721 during the movement, so that the first locking mechanism 4 is unlocked, and the seat cushion frame 2 will rotate relative to the mounting assembly 1. Since the abutting portion 721 can abut against the driving member 6 when it moves to the top of the first sliding groove 711, the user can know whether the abutting portion 721 has reached the predetermined position where it can abut against the driving member 6. In this way, the user does not need to constantly check whether the abutting portion 721 has moved to the above-mentioned predetermined position, which can save time, improve work efficiency, and enhance the user's experience.

[0083] The passenger pulls the first pulling member 8, and the abutting portion 721 slides from bottom to top in the first sliding groove 711 until it slides to the top of the first sliding groove 711, so that the abutting portion 721 abuts against the driving member 6. When the backrest frame 3 rotates relative to the seat cushion frame 2, the driving member 6 rotates with the backrest frame 3. During the rotation of the driving member 6, the abutting portion 721 can be driven to rotate, and then the first linkage member 71 can be driven to rotate, so that the first locking mechanism 4 is unlocked.

[0084] In some embodiments, see Figure 6 The seat 100 further includes a first spring 9, one end of which is mounted on the first linkage member 71. The connecting portion 722 is formed with a hole, and the other end of the first spring 9 is inserted into the hole.

[0085] When the first pulling member 8 is pulled and the abutting portion 721 slides in the first sliding groove 711, the first spring 9 is elastically deformed and generates elastic force. When the first pulling member 8 is released, the first spring 9 releases the elastic force, making it easier for the abutting portion 721 to return to the initial state.

[0086] For example, refer to Figure 6 The first spring 9 is connected to the lower part of the abutting portion 721. When the first pulling member 8 is pulled and the abutting portion 721 moves upward to the upper end of the first sliding groove 711, the first spring 9 generates elastic deformation. When the first pulling member 8 is released, the first spring 9 releases the elastic force, the elastic deformation is restored, and the abutting portion 721 is driven to move downward, so that the abutting portion 721 is more easily restored to the initial state.

[0087] In some embodiments, Fig.10 As shown, Fig.10 This is a structural schematic diagram of the driving member 6 and the abutment portion 721 provided in an embodiment of the present application. During the movement of the driving member 6 against the abutment portion 721, the angle α between the tangential direction of the rotation of the driving member 6 and the tangential direction of the rotation of the abutment portion 721 is less than or equal to 45°.

[0088] See also Fig.10 , Fig.10 The angle α between the tangential direction of the middle driving member 6 and the tangential direction of the abutting portion 721 is approximately equal to 6°. Assuming the output force is F0 and the input force is F1, F0=F1 cos6°=0.99F1, and the force transmission efficiency is close to 100%.

[0089] The smaller the angle between the tangential direction of rotation of the driving member 6 and the tangential direction of rotation of the abutment portion 721, the higher the transmission efficiency of the output force, and the smaller the operating force required by the passenger to adjust the seat 100, thereby improving the user's convenience and adjustment efficiency, and further improving the passenger experience.

[0090] See also Fig.11 , Fig.11 Another structural schematic diagram of the driving member 6 and the abutment portion 721 provided in the embodiment of the present application when they are in abutment, in which the angle between the tangential direction of the rotation of the driving member 6 and the tangential direction of the rotation of the abutment portion 721 is approximately equal to 60°. Assuming that the output force is F0 and the input force is F1, at this time F0 = F1 cos60° = 0.5F1, the force transmission efficiency is approximately 50%.

[0091] In some embodiments, Figure 1 As shown, the seat cushion frame 2 has two seat cushion side walls 21 arranged opposite to each other. Fig.10 As shown, the seat side wall 21 is formed with a second sliding groove 211 . The driving member 6 is located at one side of the seat side wall 21 , and the linkage assembly 7 is located at a side of the seat side wall 21 away from the driving member 6 , wherein the abutment portion 721 is disposed in the second sliding groove 211 .

[0092] When the backrest frame 3 rotates relative to the seat cushion frame 2, the driving member 6 rotates with the backrest frame 3. The first pulling member 8 is pulled, and the abutting portion 721 slides in the first sliding groove 711 until it abuts against the driving member 6. The driving member 6 rotates to drive the abutting portion 721 to rotate in the second sliding groove 211, thereby driving the first linkage member 71 to rotate, so that the first locking mechanism 4 is unlocked.

[0093] By providing the second sliding groove 211, the abutting portion 721 can pass through the second sliding groove 211 and abut against the driving member 6. The driving member 6 and the linkage assembly 7 are arranged on opposite sides, which can improve space utilization and save more space.

[0094] For example, see Figure 4 The driving member 6 is located on a side of one of the seat cushion side walls 21 close to the other seat cushion side wall 21 , and the linkage assembly 7 is located on a side of one of the seat cushion side walls 21 away from the other seat cushion side wall 21 .

[0095] Alternatively, the driving member 6 is located at a side of one of the cushion side walls 21 away from the other cushion side wall 21, and the linkage assembly 7 is located at a side of one of the cushion side walls 21 close to the other cushion side wall 21. Of course, the driving member 6 and the linkage assembly 7 are arranged on the same side, and at this time, the second sliding groove 211 may not be provided.

[0096] It is understandable that there are multiple ways to unlock the second locking mechanism 5. As shown above, since the first pulling member 8 is connected to the second locking mechanism 5, the second locking mechanism 5 can be unlocked. Pulling the first pulling member 8 to unlock the second locking mechanism 5 can cause the backrest frame 3 to rotate relative to the seat cushion frame 2, and then the driving member 6 rotates with the backrest frame 3. Of course, the user can also directly operate the second locking mechanism 5 to unlock.

[0097] Thus, the user can unlock the backrest frame 3 alone, or adjust the backrest frame 3 and the seat cushion frame 2 at the same time, which provides the user with a variety of options and improves the user's experience.

[0098] Exemplarily, the second locking mechanism 5 may include a regulator unlocking handle 51. Figure 4 The user can directly move the adjuster unlocking handle 51 to put the backrest frame 3 and the seat cushion frame 2 in an unlocked state.

[0099] In some embodiments, see Figure 1 The seat 100 further includes a first buckle 10 , which is mounted on the backrest frame 3 , and the first buckle 10 can be connected to the first pulling member 8 .

[0100] In order to enable the first pulling member 8 to simultaneously drive the linkage assembly 7 and the second locking mechanism 5 to move. The first pulling member 8 has two output ends and one input end. The input end can be connected to the first buckle 10. One of the output ends can be connected to the linkage assembly 7, and the other output end can be connected to the second locking mechanism 5.

[0101] The user can pull the first pulling member 8 by twisting the first buckle 10 to unlock the backrest frame 3 and the seat cushion frame 2 , thereby allowing the backrest frame 3 to rotate relative to the seat cushion frame 2 .

[0102] It is understandable that the seat 100 may further include a backrest (not shown in the figure), which is arranged on the backrest frame 3. Part of the first pulling member 8 may be located in the internal space formed by the backrest and the backrest frame 3, the first buckle 10 may be arranged outside the backrest and the backrest frame 3, and the input end of the first pulling member 8 extends out of the backrest and is connected to the first buckle 10.

[0103] Exemplarily, the first pulling member 8 may be a cable structure, and may include a plurality of cables and a connecting port.

[0104] For example, see Fig.12 , Fig.12 One of the exploded views of the seat 100 provided in the embodiment of the present application, the first pull member 8 includes a first cable 81, a second cable 82 and a third cable 83. The first pull member 8 also includes a switching component 84. The switching component 84 has a first connection port (not shown in the figure), a second connection port (not shown in the figure) and a third connection port (not shown in the figure). The first cable 81 is connected to the first connection port, the second cable 82 is connected to the second connection port, and the third cable 83 is connected to the third connection port. The first connection port is connected to the second connection port and the third connection port.

[0105] In some embodiments, Fig.12 As shown, the seat 100 further includes a second pulling member 20, a third pulling member 30 and a transmission member 40. One end of the second pulling member 20 is connected to the linkage assembly 7. One end of the third pulling member 30 is connected to the first locking mechanism 4. The transmission member 40 is rotatably connected to the seat cushion frame 2. The other end of the second pulling member 20 and the other end of the third pulling member 30 are respectively connected to the two ends of the transmission member 40.

[0106] Among them, Fig.13 As shown, Fig.13 This is a partial structural diagram of a seat provided in an embodiment of the present application. The distance between the other end of the second pull member 20 and the rotation axis of the transmission member 40 is smaller than the distance between the other end of the third pull member 30 and the rotation axis of the transmission member 40. Thus, the travel can be enlarged, so that the third pull member 30 can achieve a greater range of movement. This improves the convenience of use and the efficiency of adjustment for users, thereby improving the experience of passengers.

[0107] In some embodiments, Fig.12 As shown, the mounting assembly 1 includes a first slide rail 11 and a second slide rail 12. The second slide rail 12 is slidably connected to the first slide rail 11. The seat cushion frame 2 is rotatably connected to the second slide rail 12, and the rotation axis of the seat cushion frame 2 is perpendicular to the sliding direction of the second slide rail 12, and the seat cushion frame 2 has a normal state and an inclined state relative to the second slide rail 12.

[0108] The second slide rail 12 can rotate relative to the first slide rail 11. Fig.14 As shown, Fig.14 It is a schematic diagram of the structure when the seat cushion frame 2 slides to the front, thereby driving the seat cushion frame 2 to slide forward and backward, so that the user can adjust the front and rear position, thereby increasing the entry and exit space for rear passengers.

[0109] In some embodiments, Fig.15 As shown, Fig.15 for Fig.13 In the partial enlarged view of the position A in the middle, the seat 100 also includes a limit assembly 50 and a retaining mechanism 60. The limit assembly 50 is connected to the first slide rail 11. The retaining mechanism 60 is connected to the seat cushion frame 2 and the second slide rail 12. The retaining mechanism 60 is used to keep the seat cushion frame 2 in an inclined state. In this way, the retaining mechanism 60 can keep the seat cushion frame 2 in an inclined state, and will not suddenly return to press on the feet and legs of the rear passengers, thereby ensuring the safety of the rear passengers and improving the safety factor of the seat 100.

[0110] When the seat cushion frame 2 is in a tilted state and moves relative to the first slide rail 11, the retaining mechanism 60 is also used to contact the limiting assembly 50 to restore the seat cushion frame 2 to a normal state. In this way, the retaining mechanism 60 can restore the seat cushion frame 2 to a normal state without the need for manual adjustment by the passenger, thus simplifying the operation steps, improving the convenience of use and the efficiency of adjustment for the user, and facilitating the rapid reset of the seat 100.

[0111] In some embodiments, the holding mechanism 60 includes a holding component 601 and a return component 602. The holding component 601 is movably connected to the seat cushion frame 2 and the second slide rail 12, and is used to move synchronously with the rotation of the seat cushion frame 2, and has a first limit portion 60131. The return component 602 is movably connected to the second slide rail 12, and has a second limit portion 60211.

[0112] In which, when the seat cushion frame 2 is in a tilted state and moves relative to the first slide rail 11, the return assembly 602 contacts and moves relative to the limit assembly 50, and the second limit portion 60211 abuts against the first limit portion 60131, driving the retaining assembly 601 to move, so that the seat cushion frame 2 returns to a normal state.

[0113] When the seat cushion frame 2 is in the tilted state, the holding assembly 601 can keep the seat cushion frame 2 in the tilted state.

[0114] During the movement, the first limiting portion 60131 of the holding assembly 601 can abut against the second limiting portion 60211 of the restoring assembly 602, and the restoring assembly 602 can contact and move relative to the limiting assembly 50. In this way, driven by the restoring assembly 602, the holding mechanism 60 can move relative to the limiting assembly 50, release the tilted state of the cushion frame 2, and restore the cushion frame 2 to a normal state.

[0115] The retaining component 601 can restore the seat cushion frame 2 to a normal state, and can automatically restore to a suitable angle for the passengers, ensuring that the passengers always sit stably in their original positions after the rear passengers have successfully entered and exited.

[0116] In order to enable the holding assembly 601 to keep the seat cushion frame 2 in an inclined state, in some embodiments, as Fig.15 As shown, the holding assembly 601 includes a first holding member 6011 , a second holding member 6012 and a third holding member 6013 . The restoring assembly 602 includes a first restoring member 6021 .

[0117] One end of the first retaining member 6011 is connected to the seat cushion frame 2, and the other end is rotatably connected to the second slide rail 12, and the rotation axis is parallel to the rotation axis of the seat cushion frame 2. One end of the second retaining member 6012 is rotatably connected to the first retaining member 6011, and the rotation axis is parallel to the rotation axis of the seat cushion frame 2. One end of the third retaining member 6013 is rotatably connected to the other end of the second retaining member 6012, and the other end is rotatably connected to the second slide rail 12, and the rotation axes of both ends are parallel to the rotation axis of the seat cushion frame 2.

[0118] The third retaining member 6013 is formed with a first limiting portion 60131 .

[0119] When the seat cushion frame 2 is in an inclined state and moves relative to the first slide rail 11, the first retaining member 6011, the second retaining member 6012 and the third retaining member 6013 can form a triangular structure with stability, so that the seat cushion frame 2 can be maintained in an inclined state. Exemplarily, the second retaining member 6012 and the third retaining member 6013 are arranged side by side, in a cross-arrangement state with the first retaining member 6011, and together with the second slide rail 12 form a triangular stable structure.

[0120] It is understandable that, in order to enable the holding assembly 601 to form a triangular stable structure when in a tilted state, the arrangement positions of the components in the holding assembly 601 can be arranged according to actual needs. The specific arrangement can be selected according to actual conditions, and this application does not limit it.

[0121] The first restoring member 6021 is rotatably connected to the second slide rail 12 , and the rotation axis is parallel to the rotation axis of the seat cushion frame 2 . The first restoring member 6021 is formed with a second limiting portion 60211 .

[0122] The first return member 6021 is rotatably connected to the second slide rail 12, so that the first return member 6021 can rotate and abut against the limiting assembly 50, thereby causing the second limiting portion 60211 to rotate, so that the tilting state of the seat cushion frame 2 can be broken by the abutment between the first return member 6021 and the limiting assembly 50.

[0123] In some embodiments, Fig.15 As shown, the limiting assembly 50 includes a first protrusion 501. The first protrusion 501 is located at one side of the first slide rail 11.

[0124] Reference Fig.15 When the first return member 6021 is located on the right side of the first protrusion 501 and moves to the left, the first protrusion 501 and the first return member 6021 contact each other, and the first return member 6021 rotates counterclockwise, so that the second limiting portion 60211 abuts against the first limiting portion 60131 counterclockwise, so that the third retaining member 6013 rotates, causing the retaining assembly 601 to lose its stability as a whole.

[0125] like Fig.15 As shown, the restoring assembly 602 further includes a second restoring member 6022 and a third restoring member 6023. One end of the second restoring member 6022 is rotatably connected to the second slide rail 12, and a third limiting portion 60221 is formed on the circumference of the second restoring member 6022. The third restoring member 6023 is rotatably connected to the second restoring member 6022.

[0126] When the seat cushion frame 2 is not fully restored to the normal state, Fig.16 As shown, Fig.16 Schematic diagram of the structure when the third restoring member 6023 abuts against the first protrusion 501. At this time, the third restoring member 6023 can abut against the first protrusion 501, so that the seat cushion frame 2 cannot continue to move to the left when in the tilted state, thereby avoiding damage to the passengers when the position of the rear passengers returns to a normal state.

[0127] When the seat cushion frame 2 gradually returns to the normal state, refer to Fig.15 The first limiting portion 60131 and the third limiting portion 60221 can abut against each other, and the first limiting portion 60131 rotates counterclockwise to drive the third restoring member 6023 to rotate counterclockwise, so that the third restoring member 6023 can pass over the first protrusion 501.

[0128] In some embodiments, see Fig.17 , Fig.17 The second exploded view of the seat provided in the embodiment of the present application, the seat 100 further includes a second spring 70. Fig.18 As shown, Fig.18 for Fig.15 The structure shown is a schematic diagram of the structure on the other side, in which one end of the second spring 70 is connected to the second slide rail 12 , and the other end is connected to the second retaining member 6012 .

[0129] During the process of the seat cushion frame 2 turning over, the second spring 70 undergoes elastic deformation. During the process of the seat cushion frame 2 returning to the normal state, the second spring 70 releases its elastic force and recovers its elastic deformation.

[0130] In some embodiments, see Fig.15 The seat 100 further comprises a third spring 80. One end of the third spring 80 is connected to the seat cushion frame 2, and the other end is connected to the second return member 6022.

[0131] During the turning over of the seat cushion frame 2, the third spring 80 undergoes elastic deformation. During the returning of the seat cushion frame 2 to the normal state, the second spring 70 releases elastic force, elastically deforms and recovers, driving the seat cushion frame 2 to return to the normal state. This makes it easier for the seat cushion frame 2 to return to the normal state.

[0132] Exemplarily, the seat 100 further includes a locking block (not shown in the figure), and the second slide rail 12 is provided with an escape hole (not shown in the figure). The locking block is slidably connected to the first slide rail 11 and is inserted into the escape hole, and at this time, the first slide rail 11 and the second slide rail 12 are in a locked state.

[0133] During the flipping process of the cushion frame 2 , the locking block is pressed against to disengage the locking block from the avoidance hole, and the first slide rail 11 and the second slide rail 12 are in an unlocked state, so that the second slide rail 12 can slide relative to the first slide rail 11 .

[0134] When the seat cushion frame 2 returns to the normal state, the locking block is inserted into the avoidance hole again, and the first slide rail 11 and the second slide rail 12 are in a locked state.

[0135] For example, Fig.13 As shown, the seat 100 further includes a rear connecting rod 90, a connecting plate 91 and a slide rail unlocking handle 92. One end of the rear connecting rod 90 is rotatably connected to the seat cushion frame 2, and the other end is connected to one end of the connecting plate 91. The other end of the connecting plate 91 is connected to the slide rail unlocking handle 92.

[0136] During the flipping process of the seat cushion frame 2, the rear connecting rod 90 rotates to drive the connecting plate 91 to press down the slide rail unlocking handle 92, and the slide rail unlocking handle 92 abuts against the locking block, so that the locking block disengages from the avoidance hole, so that the first slide rail 11 and the second slide rail 12 are in an unlocked state, so that the second slide rail 12 can slide relative to the first slide rail 11.

[0137] When the seat cushion frame 2 returns to the normal state, the force pressing down the slide rail unlocking handle 92 disappears, the slide rail unlocking handle 92 and the locking block are separated, and the locking block is inserted into the avoidance hole again, and the first slide rail 11 and the second slide rail 12 are in a locked state.

[0138] For example, see Figure 1 The seat 100 further includes a second buckle 93, which is used to abut against the locking block to disengage the locking block from the avoidance hole, so that the first slide rail 11 and the second slide rail 12 are in an unlocked state.

[0139] The user can pry the second buckle 93 so that the second buckle 93 abuts against the locking block and the locking block disengages from the avoidance hole, so that the first slide rail 11 and the second slide rail 12 are in an unlocked state, thereby allowing the second slide rail 12 to slide relative to the first slide rail 11.

[0140] By providing the second buckle 93, when the user only needs to adjust the front and rear position of the seat 100, the front and rear position of the seat 100 can be adjusted by simply turning the second buckle 93. Multiple options are provided for the user, which improves the convenience of use and the efficiency of adjustment.

[0141] In some embodiments, Fig.15 As shown, the limiting assembly 50 further includes a second protrusion 502, which is located at one side of the first slide rail 11. The second protrusion 502 is used to cooperate with the third retaining member 6013 to limit the movement stroke of the second slide rail 12 relative to the first slide rail 11.

[0142] For example, see Fig.19 , Fig.19 The fourth partial enlarged view of a seat provided in an embodiment of the present application shows that the first protrusion 501 and the second protrusion 502 are located on the same side of the first slide rail 11 and are staggered.

[0143] It is understandable that there are many ways to make the second slide rail 12 slide relative to the first slide rail 11. This application does not make any specific restrictions on this, and the specific method can be selected according to actual conditions.

[0144] In some embodiments, Fig.12 As shown, the seat 100 further includes two torsion bars 94 arranged opposite to each other. One end of the torsion bar 94 is penetrated through the seat cushion side wall 21.

[0145] The seat 100 further includes a forward tilting rod 95 , in which a special-shaped slot is formed, and the other end of the torsion bar 94 is engaged with the forward tilting rod 95 via the special-shaped slot.

[0146] When the seat cushion frame 2 is in a normal state, the torsion bar 94 undergoes elastic deformation. When the seat cushion frame 2 is in an inclined state, the torsion bar 94 releases elastic force, and the elastic deformation is restored, driving the seat cushion frame 2 to flip. This makes it easier for the seat cushion frame 2 to flip.

[0147] In addition, if Fig.17 As shown, in order to realize the rotational connection and automatic return of the first retaining member 6011, the second retaining member 6012, the third retaining member 6013, the first return member 6021, the second return member 6022 and the third return member 6023, the seat may further include a torsion spring 96 and a rotating shaft 97. The torsion spring 96 may be used to return the above components to a certain position, and the rotating shaft 97 may realize the rotational connection of the above components, and the specific number and connection position may be set according to actual conditions.

[0148] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
