Description

Technical Field

[0001] The present invention relates to the field of seat technology, and more particularly to a seat cushion lock, a seat and a vehicle. Background Art

[0002] The seat is an important part of the car. Generally, in order to make full use of the space behind the seat, the car seat is generally designed with a flip structure so that the seat cushion can be flipped forward, thereby making the rear space larger and increasing the space utilization rate.

[0003] Since the seat is designed with a flipping structure, the seat may flip forward when it is not needed. For example, CN220391071U discloses a device for flipping a seat cushion forward and laying the backrest flat, including a seat cushion bracket and a backrest bracket, the seat cushion bracket includes a first mounting base, a first support arm and a seat cushion frame for mounting the seat cushion, the first mounting base and the first support arm are hinged to each other to form a first rotation fulcrum; the backrest bracket includes a second mounting base, a second support arm and the backrest frame, the second mounting base and the second support arm are hinged to each other to form a second rotation fulcrum. The seat can be flipped, but the seat cannot be locked, and the seat cushion may flip when it is not needed, posing a certain safety hazard. In order to keep the seat fixed when it is not needed, the seat is also designed with a seat cushion lock, which can be used to lock the seat cushion when it is not needed to flip the seat cushion. CN216508023U discloses a seat cushion assembly that can be unlocked and flipped in multiple directions. Its locking mechanism includes a hook, a hook rotating shaft equipped with a return spring, and a hook mounting plate. The front end of the hook is bound with an unlocking pull belt, and the rear end is hooked on the handle. The hook can be detached from the handle by pulling the unlocking pull belt to unlock the flip connection component. The unlocking steps are simple and easy to operate.

[0004] However, the various components of the seat cushion lock are directly arranged under the seat cushion, and are easily bumped by the outside after being turned over, resulting in damage to the seat cushion lock, thereby affecting the normal use of the seat cushion lock. Summary of the invention

[0005] The purpose of the present application is to provide a seat cushion lock, a seat and a vehicle, which are used to solve the problem that the existing seat cushion lock structure is easily damaged by external collisions.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] On the one hand, an embodiment of the present application provides a seat cushion lock for installation on a seat cushion. The seat cushion lock includes a mounting piece, a snap-on assembly, and a handle. A mounting cavity is formed inside the mounting piece, and has a first opening and a second opening that are connected to the mounting cavity. The snap-on assembly is located in the mounting cavity and is movably connected to the mounting cavity. A portion of the snap-on assembly is used to snap-on or separate with the lock of the seat cushion through the first opening. A portion of the handle passes through the second opening, extends deep into the mounting cavity, and is connected to the snap-on assembly, and is used to drive the snap-on assembly to move so as to separate the snap-on assembly from the lock of the seat cushion.

[0008] According to the above technical means, the seat cushion lock provided by the embodiment of the present application has an installation cavity formed inside the installation part, and the interior of the installation part can provide installation space for the snap-in assembly and the handle, and at the same time play a protective role. The first opening can make it easy to snap-in or separate the snap-in assembly from the seat cushion lock, and the second opening can facilitate the hand to extend into the installation cavity to connect with the snap-in assembly, so as to drive the snap-in assembly to move and realize the snap-in or separation of the snap-in assembly from the lock. At the same time, since the snap-in assembly is located in the installation cavity, it will not be exposed after the seat cushion is turned over. The installation part can protect the snap-in assembly, so that the user will not directly touch the snap-in assembly, avoid damage to the snap-in assembly, and thus ensure the normal use of the seat cushion lock.

[0009] In a possible embodiment, the mounting member includes a first mounting plate, a second mounting plate, and a connecting member. The second mounting plate is arranged relative to the first mounting plate and spaced apart. The connecting member is detachably connected to the first mounting plate and the second mounting plate. The space between the first mounting plate and the second mounting plate forms a mounting cavity, and forms a first opening and a second opening.

[0010] According to the above technical means, when the clamping assembly is arranged between the first mounting plate and the second mounting plate, the first mounting plate and the second mounting plate can protect the clamping assembly on both sides of the clamping assembly. Since the mounting member is composed of a plate-shaped structural assembly, the structure is simple and the manufacturing is more convenient. At the same time, the connecting member is detachably connected to the first mounting plate and the second mounting plate. In this way, when the clamping assembly needs to be disassembled and repaired, the user can separate the first mounting plate and the second mounting plate by removing the connecting member from the first mounting plate and the second mounting plate, so that the clamping assembly can be taken out, which is simple, convenient and easy to implement.

[0011] In a possible implementation manner, at least one first bending portion is formed on a peripheral side of the first mounting plate, and the first bending portion bends toward a side where the first mounting plate and the second mounting plate are close to each other.

[0012] According to the above technical means, the first bending portion can also protect the clamping assembly, preventing the clamping assembly from being hit at the position where the first bending portion is located.

[0013] In a possible implementation manner, at least one second bending portion is formed on a peripheral side of the second mounting plate, and the second bending portion bends toward a side where the first mounting plate and the second mounting plate are close to each other.

[0014] According to the above technical means, the second bending portion can also protect the clamping assembly, preventing the clamping assembly from being hit at the position where the second bending portion is located.

[0015] In a possible implementation, the connecting member includes a first fastener and a second fastener. The first fastener passes through the first mounting plate and the second mounting plate. The second fastener is disposed on the first fastener and is threadedly connected to the first fastener.

[0016] According to the above technical means, the first mounting plate and the second mounting plate can be connected together relatively firmly through the threaded connection of the first fastener and the second fastener.

[0017] In a possible implementation, the seat lock further includes a limit assembly. The limit assembly is located on a side of the first opening of the mounting member and is connected to the mounting member. The limit assembly forms a limited space, and a portion of the handle located outside the mounting cavity passes through the limited space. The limit assembly is used to limit the handle from shaking in a direction parallel to the plane where the second opening is located.

[0018] According to the above technical means, since the limiting assembly forms a limited space, a portion of the handle outside the installation cavity passes through the limited space. In this way, a portion of the handle is located in the limited space. At the same time, the limiting assembly is used to limit the handle from shaking in a direction parallel to the plane where the second opening is located. In this way, the handle can be kept stable by the action of the limiting assembly, and is not prone to shaking in the above direction. When operating the handle, it is more stable and can better drive the clamping assembly to move.

[0019] In a possible embodiment, the limit assembly includes a first limit member. The first limit member includes two first limit plates and a connecting portion. The two first limit plates are arranged relatively spaced apart. The connecting portion is located between the two first limit plates and connected to the two first limit plates. Part of the handle is located between the two first limit plates and abuts against the two first limit plates.

[0020] According to the above technical means, the handle can remain stable in the arrangement direction of the two first limiting plates without shaking under the limiting effect of the two first limiting plates.

[0021] In a possible embodiment, the first limiting plate includes a first limiting portion and a second limiting portion that are connected to each other. The two first limiting portions are arranged at a relative interval, and the two second limiting portions are arranged at a relative interval. The spacing between the two first limiting portions is greater than the spacing between the two second limiting portions. The handle includes a first connecting portion and a second connecting portion. One end of the first connecting portion is connected to the snap-on assembly. One end of the second connecting portion is connected to the other end of the first connecting portion, and an extension direction of the second connecting portion intersects with an extension direction of the first connecting portion. A portion of the first connecting portion is located between the two first limiting portions, and the second connecting portion passes through between the two second limiting portions and abuts against the two second limiting portions.

[0022] According to the above technical means, a step-changing clamping space is formed along the arrangement direction of the first limiting part and the second limiting part. The second connecting part remains stable under the abutment of the second limiting parts on both sides, and will not shake along the arrangement direction of the two second limiting parts, so that it can be operated more stably.

[0023] In a possible implementation, the limiting assembly further includes a second limiting plate, which is located on one side of the two first limiting plates in a direction perpendicular to the arrangement direction of the two first limiting plates. A protrusion is formed on one side of the second limiting plate close to the two first limiting plates, and the protrusion abuts against the handle.

[0024] According to the above technical means, the raised portion can further limit the shaking of the handle in the arrangement direction perpendicular to the two first limiting plates, that is, limit the shaking of the handle as a whole upward, thereby ensuring the stability of the handle.

[0025] In a possible implementation, the seat lock further includes a fixing plate, which is detachably connected to the first limiting plate, the second limiting plate and the mounting member.

[0026] According to the above technical means, by setting a fixed plate, the first limit plate, the second limit plate and the mounting member can be connected to each other. When disassembling, the first limit plate, the second limit plate and the mounting member can be directly removed from the fixed plate, which is convenient and easy to operate. Of course, in other embodiments, the first limit plate and the second limit plate can also be directly connected to the mounting member.

[0027] In a possible embodiment, the fixing plate includes a first fixing portion. The first fixing portion is located on a side of the second mounting plate away from the first mounting plate. The connecting member includes a first fastener and a second fastener. The first fastener passes through the first mounting plate, the second mounting plate and the first fixing portion. The second fastener is disposed on the first fastener and is threadedly connected to the first fastener.

[0028] According to the above technical means, the first fastener and the second fastener can be used to connect the first mounting plate and the second mounting plate, and the mounting member can also be connected to the fixing member. In this case, the connection between the mounting member and the fixing member can be achieved without setting up additional connecting components and connecting structures, the connection is convenient and easy to achieve, and the structure is relatively simple.

[0029] In a possible embodiment, the fixing plate further includes a second fixing portion. The second fixing portion is connected to the first fixing portion and is arranged to intersect with the first fixing portion, and is located on the side of the second limiting plate away from the first limiting plate. A supporting portion is formed at one end of the first limiting plate close to the second limiting plate. The seat lock further includes a third fastener. The third fastener passes through the second limiting plate and the second fixing portion, and extends into the supporting portion, and is threadedly connected to the supporting portion.

[0030] According to the above technical means, since the third fastener penetrates the second limit plate and the second fixing portion, the fixing plate and the second limit plate can be connected to each other. Since the third fastener also extends into the abutting portion, it is threadedly connected to the abutting portion. In this way, the third fastener can be connected to the first limit plate. In this way, through the cooperation of the third fastener and the abutting portion, the fixing member can be connected to the first limit plate and the second limit plate and installed together.

[0031] In a possible embodiment, the clamping assembly includes an elastic member, a first clamping member, and a second clamping member. One end of the elastic member is connected to the mounting member. The first clamping member is rotatably connected to the mounting member. The peripheral wall of the first clamping member is connected to the other end of the elastic member, and a hook is formed on the peripheral wall. The hook is used to be clamped with the lock of the seat cushion. The second clamping member is rotatably connected to the mounting member, and the peripheral wall is connected to the handle. A portion of the second clamping member is used to abut against the peripheral wall of the first clamping member to limit the rotation of the first clamping member, and is also used to separate from the peripheral wall of the first clamping member when driven by the handle.

[0032] According to the above technical means, the first clamping member can rotate under the action of the elastic member, so that the hook of the first clamping member is separated from or engaged with the lock buckle of the seat cushion. When the user operates the handle, the second clamping member can be rotated, so that the second clamping member and the peripheral wall of the first clamping member are separated from each other. In this way, the first clamping member can be engaged with or separated from the seat cushion under the action of the elastic member.

[0033] On the other hand, an embodiment of the present application provides a seat, comprising any of the above-mentioned seat cushion locks.

[0034] Since the seat provided in the embodiment of the present application includes any of the above-mentioned seat cushion locks, it can solve the same technical problems as the above-mentioned seat cushion locks and achieve the same technical effects, which will not be repeated here.

[0035] On the other hand, an embodiment of the present application provides a vehicle, including the above-mentioned seat.

[0036] Since the vehicle provided in the embodiment of the present application includes the above-mentioned seat, it can solve the same technical problems as the above-mentioned seat and achieve the same technical effects, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0058] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0059] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0060] As people's living standards improve, cars have gradually become people's main means of transportation. In order to increase the use space of the car trunk, the cushions of the rear seats of some cars can be flipped forward to increase the use space of the trunk.

[0061] Since the seat cushion can be flipped forward, in some unexpected situations, the seat cushion of the car may be passively flipped forward, thereby affecting the safety of passengers. Based on this, the embodiment of the present application provides a vehicle. Among them, the embodiment of the present application does not specifically limit the specific type of the vehicle. For example, the vehicle provided in the embodiment of the present application can be an electric car, a hybrid car, or a solar car.

[0062] In order to realize the basic functions of a car, the vehicle may include components such as a body, a chassis, a power system, and an electrical system.

[0063] The vehicle body may include a vehicle frame, vehicle doors, and vehicle windows. The vehicle frame may form the overall shape of the vehicle exterior and form a seating space for accommodating passengers. The vehicle doors may be rotatably connected to the vehicle frame and may open or close the interior passenger space. The vehicle windows may be installed on the vehicle doors or the vehicle frame to facilitate passengers to observe the external environment.

[0064] The chassis may include components such as a transmission system and a drive system. The drive system can drive the wheels to rotate. Depending on the drive mode of the drive system, the drive system can be divided into front-wheel drive, rear-wheel drive, and four-wheel drive arrangements. The transmission system can transfer the power generated by the engine to the wheels.

[0065] The power system can provide power for the vehicle so that the vehicle can complete basic driving functions. Depending on the type of vehicle, the composition of the power system is also different. Exemplarily, when the vehicle is an electric vehicle, the power system may include an electric motor.

[0066] In order to power electrical components such as motors, the vehicle provided in the embodiments of the present application further includes a battery system. The battery system may include a battery pack, which may be used to provide electrical energy. The battery pack may be electrically connected to the electrical components of the vehicle. In this way, the electrical energy of the battery pack may be transferred to the electrical components of the vehicle for powering.

[0067] In addition, for the user's riding, the vehicle provided in the embodiment of the present application also includes a seat. 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 first seat 10 and a second seat 20 arranged side by side. The seat 100 may be installed on a carpet assembly 30 in a vehicle cabin. The first seat 10 and the second seat 20 may be a four-six-point seat 100. For example, the first seat 10 may be a six-point seat 100, and the second seat 20 may be a four-point seat 100.

[0068] Continue to refer to Figure 1 , the first seat 10 may include a first backrest 11 and a first cushion 12. The second seat 20 may include a second backrest 21 and a second seat 20. The first backrest 11 may be rotatably connected to the vehicle body, and the first cushion 12 may also be rotatably connected to the vehicle body. In this way, both the first backrest 11 and the first cushion 12 may be rotated to increase the luggage storage space at the rear of the vehicle. Exemplarily, the first cushion 12 may be turned forward by rotating, and the first backrest 11 may also be turned forward by rotating to fully increase the luggage storage space.

[0069] It is understandable that the connection of the second seat 20 can be similar to that of the first seat 10. Among them, the second backrest 21 can be rotatably connected to the vehicle body, and the second seat cushion 22 can also be rotatably connected to the vehicle body, and the second backrest 21 and the second seat cushion 22 can both be rotated to realize forward flipping.

[0070] It is understandable that the specific structure of the seat 100 provided in the embodiment of the present application can be designed according to actual conditions. Figure 2 As shown, Figure 2 for Figure 1 As shown in the exploded view of the first cushion 12, the first cushion 12 may include a cushion frame 121, a cushion skin 122 and a cushion foam 123. The cushion frame 121 may be composed of metal wires to form a basic skeleton shape of the cushion. Exemplarily, the cushion frame 121 may be composed of steel wires. The diameter of the steel wire may be selected according to actual conditions. Exemplarily, the diameter of the steel wire may be 5 mm. Of course, the diameter of the steel wire may also be other values, which may be specifically designed according to actual conditions, and is only described here as an example.

[0071] The cushion foam 123 can be coated on the cushion frame 121 to provide elasticity for the cushion and improve the comfort of the passenger. For example, when making the cushion foam 123, foaming can be directly performed on the cushion frame 121, so that the cushion frame 121 is directly arranged on the cushion foam 123 during the manufacturing process of the cushion foam 123.

[0072] The cushion skin 122 can be sleeved on the outside of the cushion foam 123, and the cushion skin 122 can wrap the cushion foam 123 so that the cushion foam 123 is not exposed, thereby improving the overall aesthetics of the cushion. The cushion skin 122 can be assembled into a whole by Velcro or C-shaped nails.

[0073] In order to ensure the stability of the seat cushion, Figure 1 and Figure 2 As shown, the seat 100 provided in the embodiment of the present application may further include a seat cushion lock 40. The seat cushion lock 40 may be installed on the seat cushion. Figure 1 As shown, the cushion lock 40 can be arranged below the cushion. Wherein, the cushion lock 40 can be used to lock or unlock the rotation of the cushion to prevent the cushion from rotating when it is not needed, thereby improving the safety performance of the vehicle.

[0074] like Figure 2 As shown, the seat 100 may further include a flipping mechanism 50, and the flipping mechanism 50 may be connected to the seat cushion. At the same time, the flipping mechanism 50 is also connected to the vehicle body. The flipping mechanism 50 may be used to flip the seat cushion. A lock buckle 53 may be formed on the flipping mechanism 50. The seat cushion lock 40 may be engaged with the lock buckle 53. In this way, the seat cushion lock 40 and the lock buckle may be relatively fixed, so that the seat cushion can be fixed. When the seat cushion lock 40 is separated from the lock buckle 53, the user can flip the seat cushion by operation.

[0075] Of course, in other embodiments, the above-mentioned lock buckle 53 may also be formed on the vehicle body. In this way, the seat lock 40 is engaged with the lock buckle 53. The seat lock 40 and the buckle can be relatively fixed, so that the seat lock 40 and the vehicle body are relatively fixed, and the seat can also be fixed.

[0076] In order to realize the installation of the flip mechanism 50 and the seat lock 40 and the seat cushion, as shown in FIG. Figure 2 As shown, the first seat cushion 12 may further include a plurality of mounting sheet metals 124. The seat cushion lock 40 and the flip mechanism 50 may be connected to the mounting sheet metals 124 to achieve connection with the seat cushion.

[0077] Understandably, Figure 1 The second seat cushion 22 shown may also be provided with Figure 2 The related mechanisms shown in the embodiment of the present application are described by taking the structure of the first seat cushion 12 as an example.

[0078] Next, the seat cushion lock 40 and the flip mechanism 50 are further described.

[0079] First, the seat cushion lock 40 provided in the embodiment of the present application is further introduced. Figure 3 and Figure 4 As shown, Figure 3 An exploded view of a seat cushion lock 40 provided in an embodiment of the present application, Figure 4 for Figure 3 The seat lock 40 is a cross-sectional view of a part of the structure when assembled. The seat lock 40 may include a mounting member 41, a clamping assembly 42, and a handle 43. The mounting member 41 may have a mounting cavity formed therein, and may have a first opening and a second opening communicating with the mounting cavity. In this way, the interior of the mounting member 41 may provide a mounting space for the clamping assembly 42 and the handle 43, and may also play a protective role.

[0080] The snap-on assembly 42 is located in the installation cavity and is movably connected to the installation cavity. A portion of the snap-on assembly 42 is used to snap on or off with the lock buckle 53 of the seat cushion through the first opening. In this way, since the snap-on assembly 42 is located in the installation cavity, it will not be exposed after the seat cushion is turned over. The mounting member 41 can protect the snap-on assembly 42, so that the user will not directly touch the snap-on assembly 42, thereby avoiding damage to the snap-on assembly 42, thereby ensuring the normal use of the seat cushion lock 40. At the same time, the snap-on assembly 42 can also snap on or off with the lock buckle 53 through the first opening. For example, Figure 4 As shown, the snap-fit ​​assembly 42 can be connected to the lock buckle 53 ( Figure 2 ) for connection or separation.

[0081] A portion of the handle 43 passes through the second opening and goes deep into the installation cavity, and is connected to the clamping assembly 42, and is used to drive the clamping assembly 42 to move, so that the clamping assembly 42 is separated from the lock 53 of the seat cushion. In this way, when the user is operating, the handle 43 can be used to drive the clamping assembly 42 to move, so as to separate the clamping assembly 42 from the lock 53, and then the position of the seat cushion can be adjusted. For example, Figure 3 As shown, the handle 43 can extend into the mounting cavity through the opening in front of the mounting member 41 .

[0082] Based on this, the seat lock 40 provided in the embodiment of the present application has an installation cavity formed inside the installation member 41, and the interior of the installation member 41 can provide installation space for the clamping assembly 42 and the handle 43, and at the same time play a protective role. The first opening can make it easy to clamp or separate the clamping assembly 42 and the lock buckle 53 of the seat, and the second opening can facilitate the handle 43 to extend into the installation cavity to connect with the clamping assembly 42, so as to drive the clamping assembly 42 to move, and realize the clamping or separation of the clamping assembly 42 and the lock buckle 53. At the same time, since the clamping assembly 42 is located in the installation cavity, it will not be exposed after the seat is turned over, and the installation member 41 can protect the clamping assembly 42, so that the user will not directly touch the clamping assembly 42, avoid damage to the clamping assembly 42, and thus ensure the normal use of the seat lock 40.

[0083] In some embodiments, Figure 3 As shown, the mounting member 41 may include a first mounting plate 411, a second mounting plate 412 and a connecting member 413. The second mounting plate 412 is arranged relative to the first mounting plate 411. The interval between the first mounting plate 411 and the second mounting plate 412 forms a mounting cavity, and forms a first opening and a second opening.

[0084] In this way, when the clamping assembly 42 is disposed between the first mounting plate 411 and the second mounting plate 412, the first mounting plate 411 and the second mounting plate 412 can protect the clamping assembly 42 on both sides of the clamping assembly 42. Since the mounting member 41 is a plate-shaped structural assembly, the structure is simple and the manufacturing is more convenient.

[0085] Meanwhile, the connecting piece 413 is detachably connected to the first mounting plate 411 and the second mounting plate 412. Thus, when the clamping assembly 42 needs to be disassembled for maintenance, the user can separate the first mounting plate 411 and the second mounting plate 412 by disassembling the connecting piece 413 from the first mounting plate 411 and the second mounting plate 412, thereby taking out the clamping assembly 42, which is simple, convenient and easy to implement.

[0086] Of course, the first mounting plate 411 and the second mounting plate 412 may also be connected to each other in other ways. For example, in some embodiments, the first mounting plate 411 and the second mounting plate 412 may be directly connected. In this case, the first mounting plate 411 and the second mounting plate 412 may be provided with a clamping structure respectively to achieve the clamping of the two. In this way, the first mounting plate 411 and the second mounting plate 412 are directly connected without the need to set the connector 413 for connection.

[0087] In some embodiments, Figure 3As shown, at least one first bending portion 4111 is formed on the circumferential side of the first mounting plate 411. The first bending portion 4111 is bent toward the side where the first mounting plate 411 and the second mounting plate 412 are close to each other. Figure 3 As shown, the first bending portion 4111 can also be connected to the clamping assembly 42 ( Figure 4 ) plays a protective role to prevent the clamping assembly 42 from being hit at the position where the first bending portion 4111 is located.

[0088] Similarly, in some embodiments, at least one second bending portion (not shown) is formed on the circumferential side of the second mounting plate 412. The second bending portion is bent toward the side where the first mounting plate 411 and the second mounting plate 412 are close to each other. In this way, the second bending portion can also protect the clamping assembly 42, preventing the clamping assembly 42 from being hit at the position where the second bending portion is located.

[0089] In some embodiments, Figure 3 As shown, the connecting member 413 includes a first fastener 4131 and a second fastener 4132. The first fastener 4131 penetrates the first mounting plate 411 and the second mounting plate 412. The second fastener 4132 is disposed on the first fastener 4131 and is threadedly connected to the first fastener 4131. Thus, the first mounting plate 411 and the second mounting plate 412 can be connected together more firmly through the threaded connection of the first fastener 4131 and the second fastener 4132. Exemplarily, the first fastener 4131 can be a bolt, and the second fastener 4132 can be a nut.

[0090] Of course, the connecting member 413 may also have other components. For example, in other embodiments, the connecting member 413 may only include the first fastener 4131. In this case, the first fastener 4131 may penetrate the first mounting plate 411 and be threadedly connected to the second mounting plate 412. In this way, the first mounting plate 411 and the second mounting plate 412 may also be firmly connected together through the first fastener 4131.

[0091] Continue to refer to Figure 3 In some embodiments, the cushion lock 40 further includes a limiting assembly 44. The limiting assembly 44 is located at a side where the first opening of the mounting member 41 is located, and is connected to the mounting member 41. The limiting assembly 44 forms a limiting space, and a portion of the handle 43 located outside the mounting cavity passes through the limiting space.

[0092] Since the limiting assembly 44 forms a limited space, a portion of the handle 43 outside the installation cavity passes through the limited space. In this way, a portion of the handle 43 is located in the limited space. At the same time, the limiting assembly 44 is used to limit the handle 43 from shaking in a direction parallel to the plane where the second opening is located. In this way, the handle 43 can be kept stable by the action of the limiting assembly 44, and is not easy to shake in the above direction. When operating the handle 43, it is more stable and can better drive the clamping assembly 42 to move.

[0093] Of course, in other embodiments, the seat lock 40 may not be provided with the limiting assembly 44. In this case, corresponding limiting structures may be provided on the first mounting plate 411 and the second mounting plate 412 to limit the movement of the handle 43, so that the handle 43 can be more stable and convenient for driving the clamping assembly 42 to move.

[0094] like Figure 3 As shown, the limiting assembly 44 may include a first limiting member 441. Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of the structure of a first position-limiting member 441 provided in an embodiment of the present application is shown in FIG. Figure 6 for Figure 5 The first position-limiting member 441 is a schematic structural diagram at another angle, wherein the first position-limiting member 441 includes two first position-limiting plates 4411 and a connecting portion 4412. The two first position-limiting plates 4411 are arranged relatively spaced apart. The connecting portion 4412 is located between the two first position-limiting plates 4411 and connected to the two first position-limiting plates 4411.

[0095] Part of the handle 43 is located between the two first limit plates 4411 and abuts against the two first limit plates 4411. In this way, the handle 43 can remain stable in the arrangement direction of the two first limit plates 4411 without shaking under the limiting effect of the two first limit plates 4411. Exemplarily, when the limit assembly 44 is installed on the mounting member 41, the arrangement direction of the two first limit plates 4411 can be consistent with the arrangement direction of the first mounting plate 411 and the second mounting plate 412.

[0096] In some embodiments, Figure 5 and Figure 6 As shown, the first limit plate 4411 includes a first limit portion 4413 and a second limit portion 4414 connected to each other. The two first limit portions 4413 are arranged at intervals relative to each other, and the two second limit portions 4414 are arranged at intervals relative to each other. The distance between the two first limit portions 4413 is greater than the distance between the two second limit portions 4414. Figure 7 and Figure 8 As shown, Figure 7 for Figure 5 The top view of the first stopper 441 is shown in FIG. Figure 8 for Figure 5 The front view of the first limiting member 441 shown forms a step-changing clamping space along the arrangement direction of the first limiting portion 4413 and the second limiting portion 4414 .

[0097] At the same time, if Figure 3 As shown, the handle 43 includes a first connecting portion 4412431 and a second connecting portion 4412432. One end of the first connecting portion 4412431 is connected to the clamping assembly 42 ( Figure 4 One end of the second connection portion 4412432 is connected to the other end of the first connection portion 4412431, and an extension direction of the second connection portion 4412432 intersects with an extension direction of the first connection portion 4412431.

[0098] Part of the first connection portion 4412431 is located between the two first limiting portions 4413, and the second connection portion 4412432 passes through between the two second limiting portions 4414 and abuts against the two second limiting portions 4414. Fig. 9 As shown, Fig. 9 It is a structural diagram of the assembly of the handle 43 and the limiting assembly 44. The second connecting parts 4412432 remain stable under the abutment of the second limiting parts 4414 on both sides, and will not shake along the arrangement direction of the two second limiting parts 4414, so that more stable operation can be achieved.

[0099] In some embodiments, Figure 3 As shown, the limiting assembly 44 further includes a second limiting plate 442. The second limiting plate 442 is located on one side of the two first limiting plates 4411 along a direction perpendicular to the arrangement direction of the two first limiting plates 4411. Fig.10 and Fig.11 As shown, Fig.10 A schematic diagram of the structure of a second limiting plate 442 provided in an embodiment of the present application is shown in FIG. Fig.11 for Fig.10 The second limiting plate 442 is shown in another structural diagram at another angle. The second limiting plate 442 is formed with a protrusion 4421. Fig. 9 The second limiting plate 442 is formed with the protrusion 4421 on one side close to the first limiting plate 4411 . The protrusion 4421 abuts against the handle 43 .

[0100] In this way, the protrusion 4421 can further limit the shaking of the handle 43 in the arrangement direction perpendicular to the two first limiting plates 4411, that is, limit the handle 43 from shaking upward as a whole, thereby ensuring the stability of the handle 43.

[0101] like Figure 3As shown, in some embodiments, the cushion lock 40 also includes a fixing plate 45. The fixing plate 45 is detachably connected to the first limiting plate 4411, the second limiting plate 442 and the mounting member 41, respectively. Thus, by setting the fixing plate 45, the first limiting plate 4411, the second limiting plate 442 and the mounting member 41 can be connected to each other. When disassembling, the first limiting plate 4411, the second limiting plate 442 and the mounting member 41 can be directly removed from the fixing plate 45, which is convenient to operate and easy to implement. Of course, in other embodiments, the first limiting plate 4411 and the second limiting plate 442 can also be directly connected to the mounting member 41.

[0102] Continue to refer to Figure 3 In some embodiments, the fixing plate 45 includes a first fixing portion 451. The first fixing portion 451 is located on a side of the second mounting plate 412 away from the first mounting plate 411. At this time, the first fastener 4131 penetrates the first mounting plate 411, the second mounting plate 412 and the first fixing portion 451. The second fastener 4132 is disposed on the first fastener 4131 and is threadedly connected to the first fastener 4131.

[0103] Thus, by means of the first fastener 4131 and the second fastener 4132, when the connection between the first mounting plate 411 and the second mounting plate 412 is realized, the mounting member 41 can also be connected to the fixing member. In this case, the connection between the mounting member 41 and the fixing member can be realized without setting up an additional connecting portion 4412 and a connecting structure, and the connection is convenient and easy to realize, and the structure is relatively simple. As shown above, for example, the first fastener 4131 can be a bolt, and the second fastener 4132 can be a nut.

[0104] In addition, illustratively, there may be a plurality of first fasteners 4131 and second fasteners 4132. Fastening by a plurality of first fasteners 4131 and second fasteners 4132 may achieve a more secure fixation.

[0105] It is understandable that in order to achieve the penetration of the first fastener 4131, Figure 3 As shown, corresponding avoidance holes 4422 may be opened on the first fixing portion 451 , the first mounting plate 411 and the second mounting plate 412 , so that the first fastener 4131 can pass through the first fixing portion 451 , the first mounting plate 411 and the second mounting plate 412 .

[0106] Continue to refer to Figure 3In order to realize the installation of the fixing member with the first limiting plate 4411 and the second limiting plate 442, in some embodiments, the fixing plate 45 further includes a second fixing portion 452. The second fixing portion 452 is connected to the first fixing portion 451 and is arranged to intersect with the first fixing portion 451, and is located on the side of the second limiting plate 442 away from the first limiting plate 4411.

[0107] Among them, Fig.13 As shown, Fig.13 for Figure 5 The side view of the first stopper 441 shown in FIG. Figure 3 The first limiting plate 4411 is formed with a butting portion 4415 at one end close to the second limiting plate 442. Meanwhile, the cushion lock 40 further includes a third fastener 46. The third fastener 46 penetrates the second limiting plate 442 and the second fixing portion 452, and extends into the butting portion 4415, and is threadedly connected with the butting portion 4415.

[0108] Since the third fastener 46 penetrates the second limiting plate 442 and the second fixing portion 452, the fixing plate 45 and the second limiting plate 442 can be connected to each other. Since the third fastener 46 also extends into the abutting portion 4415, it is threadedly connected to the abutting portion 4415. In this way, the third fastener 46 can be connected to the first limiting plate 4411. In this way, through the cooperation of the third fastener 46 and the abutting portion 4415, the fixing member can be connected to the first limiting plate 4411 and the second limiting plate 442 and installed together. Among them, exemplary, the third fastener 46 can be a bolt.

[0109] For example, Figure 6 As shown, the first limiting portion 4413 is plate-shaped, and one end of the first limiting portion 4413 away from the second limiting portion 4414 is bent and formed with the above-mentioned abutting portion 4415. Fig.12 As shown, Fig.12 for Figure 5 In the side view of the first limiting member 441 shown, the abutting portion 4415 has a certain length and is a boss structure, so that the third fastener 46 can be better inserted for threaded connection.

[0110] In addition, illustratively, the number of the third fastening member 46 and the number of the abutting portion may both be plural.

[0111] In addition, if Figure 3 As shown, the cushion lock 40 also includes a fourth fastener 47. The fourth fastener 47 can penetrate the second fixing portion 452 and connect with the cushion (e.g. Figure 1 The first cushion 12 is threadedly connected. In this way, the cushion lock 40 as a whole can be connected by the fourth fastener 47, which is convenient and easy to implement. Exemplarily, the fourth fastener 47 can be a bolt. At the same time, the number of the fourth fasteners 47 can also be multiple.

[0112] like Fig.13 As shown, Fig.13 for Fig.10 The top view of the second limit plate 442 shown in FIG. 4 shows, the second limit plate 442 may be provided with an avoidance hole 4422. In this way, the third fastener 46 ( Figure 3 ) can directly pass through the avoidance hole 4422, which makes installation more convenient.

[0113] In some embodiments, Fig.13 As shown, combined Fig.14 as well as Fig.15 , Fig.14 for Fig.10 The front view of the second limiting plate 442 is shown, Fig.15 for Fig.10 In the side view of the second limiting plate 442 shown in FIG. 1 , the protrusion 4421 on the second limiting plate 442 may form a depression on the other side, and may be formed by directly stamping the second limiting plate 442. Of course, in other embodiments, the protrusion 4421 may also be directly formed by adding a manufacturing material to the surface of one side of the second limiting plate 442. In this case, the surface of the second limiting plate 442 on the side where the protrusion 4421 is not provided may be a flat surface.

[0114] In order to realize that the snap-fit ​​assembly 42 can be snapped or separated with the lock buckle 53 of the seat cushion, in some embodiments, such as Figure 4 As shown, the clamping assembly 42 may include an elastic member 421, a first clamping member 422 and a second clamping member 423. One end of the elastic member 421 is connected to the mounting member 41. The first clamping member 422 is rotatably connected to the mounting member 41. The peripheral wall of the first clamping member 422 is connected to the other end of the elastic member 421, and a hook 4221 is formed on the peripheral wall. The hook 4221 can be used to clamp with the lock buckle 53 of the seat cushion.

[0115] In this way, the first clamping member 422 can rotate under the action of the elastic member 421, so that the hook 4221 of the first clamping member 422 is separated from or clamped with the lock buckle 53 of the seat cushion. Figure 4 As shown, the first clamping member 422 can rotate clockwise under the action of the elastic member 421. At this time, as the first clamping member 422 rotates, the opening of the hook 4221 gradually faces downward, and the hook 4221 can be separated from the lock buckle 53 of the seat cushion.

[0116] In addition, if Figure 4 As shown, in order to facilitate the connection between the elastic member 421 and the first clamping member 422, a hook 4222 is formed on the peripheral wall of the first clamping member 422. The hook 4222 can be hooked on one end of the elastic member 421. Exemplarily, the elastic member 421 can be a spring.

[0117] Continue to refer to Figure 4 The second clamping member 423 is rotatably connected to the mounting member 41, and the peripheral wall is connected to the handle 43. A portion of the second clamping member 423 is used to abut against the peripheral wall of the first clamping member 422 to limit the rotation of the first clamping member 422, and is also used to separate from the peripheral wall of the first clamping member 422 under the drive of the handle 43.

[0118] Thus, when the user operates the handle 43, the second clamping member 423 can be rotated, so that the second clamping member 423 and the peripheral wall of the first clamping member 422 are separated from each other. In this way, the first clamping member 422 can be connected or separated from the seat cushion under the action of the elastic member 421. For example, Figure 4 As shown, when the user operates the handle 43 to rotate counterclockwise, the second clamping member 423 rotates counterclockwise. At this time, as the second clamping member 423 rotates counterclockwise, the first clamping member 422 and the second clamping member 423 are separated from each other. Then, the first clamping member 422 can rotate clockwise under the action of the elastic member 421, so that the opening of the hook 4221 faces, so that the hook 4221 and the lock buckle 53 of the seat cushion are separated from each other.

[0119] At the same time, combined Figure 4 and Fig. 9 As shown, when the user uses the grip portion 433 to operate the handle 43, the first limit plate 4411 and the second limit plate 442 can limit the shaking of the handle 43, so that the handle 43 can be better adjusted according to the Figure 4 The seat 53 is tilted in the direction shown, driving the second clip 423 to move, thereby separating the second clip 423 from the first clip 422. When the user returns the seat cushion to its original position, the seat cushion is pressed down so that the lock buckle 53 and the hook 4221 of the first clip 422 interact with each other, so that the first clip 422 moves counterclockwise until it is engaged with the second clip 423, so that the second clip 423 can limit the clockwise movement of the first clip 422, completing the engagement between the hook 4221 and the lock buckle 53.

[0120] In addition, the elastic member 421 can also be connected to the second clamping member 423 to drive the second clamping member 423 to reset. In this way, the second clamping member 423 can be reset by the elastic member 421.

[0121] Of course, the snap-in assembly 42 provided in the embodiment of the present application may also have other structures and components, and may be specifically designed according to actual conditions, as long as the snap-in assembly 42 can be snapped into or separated from the lock buckle 53 of the seat cushion. This is only described here as an example.

[0122] For example, in some other embodiments, the clamping assembly 42 may also include only the first clamping member 422 and the handle 43. In this case, the handle 43 may be directly connected to the peripheral wall of the first clamping member 422. In this way, when the user operates the handle 43, the first clamping member 422 may be directly driven to move, so that the hook 4221 of the first clamping member 422 may be clamped or separated from the lock buckle 53 of the seat cushion.

[0123] In order to achieve the flipping of the seat cushion, in some embodiments, the flipping mechanism 50 may include a first flipping assembly and a second flipping assembly. The first flipping assembly may be connected to the vehicle body. One end of the second flipping assembly may be rotatably connected to the first flipping mechanism 50, and the other end may be rotatably connected to the seat cushion. In this way, through the first flipping assembly and the second flipping assembly, the seat cushion can be flipped with the two ends of the second flipping mechanism 50 as the rotation center, thereby achieving multiple flipping of the seat cushion.

[0124] like Fig.16 As shown, Fig.16 An exploded view of a flip mechanism 50 provided in an embodiment of the present application, wherein the first flip assembly may include two body connection brackets 51, two first hinges 54, and a first connecting rod 52. The two ends of the first connecting rod 52 are respectively connected to a body connection bracket 51, and the two body connection brackets 51 may be connected to each other. A lock buckle 53 may be formed on the first connecting rod 52.

[0125] The vehicle body mounting bracket can be connected to the vehicle body. Exemplarily, the vehicle body connecting bracket 51 can be connected to the vehicle body by bolt fastening. A vehicle body connecting bracket 51 can be installed with a first hinge 54. In this way, the vehicle body mounting bracket can be rotatably connected to other components through the first hinge 54.

[0126] Continue to refer to Fig.16 The second flip assembly may include two flip support arms 55. One end of the two flip support arms 55 is rotatably connected to a first hinge 54 respectively. In this way, the two flip support arms 55 can rotate relative to the first flip mechanism 50. At the same time, the second flip assembly also includes a second connecting rod 56. The two ends of the second connecting rod 56 are respectively connected to the other ends of the two flip support arms 55. In this way, the two flip support arms 55 can be connected to each other through the second connecting rod 56.

[0127] like Fig.16As shown, the second flip assembly also includes two second hinges 57 and two cushion mounting seats 58. The two second hinges 57 are respectively mounted at the other ends of the two flip support arms 55. The two cushion mounting seats 58 can be rotatably connected to each of the second hinges 57. In this way, the cushion mounting seat can rotate relative to the second hinges 57. At the same time, the cushion mounting seat 58 can be connected to the cushion. In this way, the cushion can rotate relative to the second hinges 57.

[0128] Among them, Fig.16 As shown, the second flip assembly may further include a fifth fastener 59, which may be connected to the cushion mounting base 58 and the cushion. In this way, the cushion mounting base 58 and the cushion may be connected to each other via the fifth fastener 59. Exemplarily, the fifth fastener 59 may be a bolt.

[0129] based on Fig.16 The turning mechanism 50 shown in FIG. Fig.17 and Fig.18 As shown, Fig.17 This is a schematic diagram of the structure of the seat cushion in a normal state. Fig.18 It is a schematic diagram of the structure when the seat cushion is in the forward flip state. Fig.17 As shown in FIG. 1 , when the seat cushion is in a normal state, the seat cushion can rotate around the first hinge 54 and the second hinge 57 as axes. The seat cushion can rotate counterclockwise around the first hinge 54 to flip forward, and the seat cushion can also rotate clockwise around the second hinge 57. After flipping, the position of the seat cushion can be as shown in FIG. Fig.18 shown.

[0130] Therefore, if Fig.19 As shown, Fig.19 The cross-sectional view of the first seat cushion 12 provided in the embodiment of the present application shows that the user can unlock the seat cushion by the handle 43 of the seat cushion lock 40. At this time, the seat cushion can be rotated under the action of the flip mechanism 50, so that the seat cushion rotates around the first hinge 54 and the second hinge 57 to realize the forward flipping of the seat cushion.

[0131] In addition, if Fig.19 As shown, the flip mechanism 50 and the mounting member 41 and other structures are all arranged in front of the bottom of the first seat cushion 12, which can provide good support for the first seat cushion 12. When a collision occurs, it can more effectively prevent the human body from moving forward and downward, thereby improving the anti-diving performance of the seat.

[0132] Of course, it is understandable that the second flip assembly provided in the embodiment of the present application may also have other component structures, as long as it can achieve the flipping of the seat cushion. The specific design can be based on actual conditions and is only described here as an example.

[0133] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
