Description

Technical Field

[0001] This application relates to the field of seat technology, specifically to a seat cushion lock, a seat, and a vehicle. Background Technology

[0002] Seats are an important component of a car. Generally, in order to make full use of the space behind the seat, car seats are designed with a flip-up structure, which allows the seat cushion to flip forward, thereby increasing the rear space and improving space utilization.

[0003] Because the seat design incorporates a flip-up structure, it can flip forward unnecessarily. For example, CN220391071U discloses a seat cushion flip-up and backrest flattening device, 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 together to form a first rotation fulcrum. The backrest bracket includes a second mounting base, a second support arm, and a backrest frame. The second mounting base and the second support arm are hinged together to form a second rotation fulcrum. While the seat can flip, it cannot be locked, and the seat cushion may flip unnecessarily, posing a safety hazard. To keep the seat fixed when not needed, a seat cushion lock is also designed to lock the seat cushion when it is not required to flip. CN216508023U discloses a seat cushion assembly for unlocking multi-directional flipping. Its locking mechanism includes a hook, a hook rotating shaft fitted with a return spring, and a hook mounting plate. The front end of the hook is bound with an unlocking pull strap, and the rear end hooks onto the handle. The hook can be released from the handle by pulling the unlocking pull strap, thereby unlocking the flipping connection component. The unlocking steps are simple and easy to operate.

[0004] However, since the various components of the aforementioned seat lock are located directly under the seat, they are easily damaged by external impacts after being flipped over, which in turn affects the normal use of the seat lock. Summary of the Invention

[0005] The purpose of this application is to provide a seat lock, seat, and vehicle to solve the problem that the existing seat lock structure is easily damaged by external impacts.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] On one hand, this application provides a seat lock for mounting on a seat. The seat lock includes a mounting member, a snap-fit ​​assembly, and a handle. The mounting member has an internal mounting cavity with a first opening and a second opening communicating with the mounting cavity. The snap-fit ​​assembly is located within the mounting cavity and is movably connected to it. A portion of the snap-fit ​​assembly is used to engage or disengage with the seat's latch through the first opening. A portion of the handle passes through the second opening, extends into the mounting cavity, and connects to the snap-fit ​​assembly, for moving the snap-fit ​​assembly to disengage it from the seat's latch.

[0008] According to the above-described technical means, the seat lock provided in this application embodiment has an internal mounting cavity. The interior of the mounting component provides mounting space for the snap-fit ​​assembly and the handle, while also providing protection. The first opening allows the snap-fit ​​assembly to easily engage or disengage from the seat's latch. The second opening allows the handle to easily reach into the mounting cavity and connect to the snap-fit ​​assembly, thereby moving the snap-fit ​​assembly and engaging or disengaging it from the latch. Furthermore, because the snap-fit ​​assembly is located within the mounting cavity, it will not be exposed when the seat is flipped. The mounting component protects the snap-fit ​​assembly, preventing the user from directly touching it and thus avoiding damage, thereby ensuring the normal use of the seat lock.

[0009] In one possible implementation, the mounting component includes a first mounting plate, a second mounting plate, and a connector. The second mounting plate is spaced apart from the first mounting plate. The connector is detachably connected to both the first and second mounting plates. The gap between the first and second mounting plates forms a mounting cavity, and also forms a first opening and a second opening.

[0010] According to the above-mentioned technical means, when the snap-fit ​​assembly is disposed between the first mounting plate and the second mounting plate, the first and second mounting plates can protect the snap-fit ​​assembly from both sides. Since the mounting component is a plate-shaped structure, the structure is simple and easier to manufacture. At the same time, the connector is detachably connected to the first and second mounting plates. Thus, when the snap-fit ​​assembly needs to be disassembled for maintenance, the user can separate the first and second mounting plates by removing the connector, thereby allowing the snap-fit ​​assembly to be removed. The operation is simple, convenient, and easy to implement.

[0011] In one possible implementation, at least one first bend is formed on the periphery of the first mounting plate. The first bend bends toward the side of the first mounting plate and the second mounting plate that are close to each other.

[0012] According to the above-mentioned technical means, the first bend can also protect the snap-fit ​​component, preventing the snap-fit ​​component from being impacted from the location of the first bend.

[0013] In one possible implementation, at least one second bend is formed on the periphery of the second mounting plate. The second bend bends toward the side of the first mounting plate and the second mounting plate that are close to each other.

[0014] According to the above-mentioned technical means, the second bend can also protect the snap-fit ​​assembly, preventing the snap-fit ​​assembly from being impacted from the location of the second bend.

[0015] In one possible implementation, the connector includes a first fastener and a second fastener. The first fastener passes through both the first mounting plate and the second mounting plate. The second fastener passes through the first fastener and is threadedly connected to it.

[0016] According to the above-mentioned 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 one possible implementation, the seat lock further includes a limiting component. The limiting component is located on the side of the mounting member where the first opening is located and is connected to the mounting member. The limiting component forms a limiting space through which a portion of the handle outside the mounting cavity passes. The limiting component is used to restrict the handle from wobbling in a direction parallel to the plane of the second opening.

[0018] According to the above technical means, since the limiting component forms a limiting space, a portion of the handle outside the mounting cavity passes through the limiting space. Thus, a portion of the handle is located within the limiting space. Simultaneously, the limiting component restricts the handle from swaying in a direction parallel to the plane containing the second opening. In this way, the handle can be kept stable by the limiting component, making it less prone to swaying, resulting in greater stability when operating the handle and better enabling the locking component to move.

[0019] In one possible implementation, the limiting assembly includes a first limiting member. The first limiting member includes two first limiting plates and a connecting portion. The two first limiting plates are disposed opposite to each other and spaced apart. The connecting portion is located between the two first limiting plates and connected to the two first limiting plates. A portion of the handle is located between the two first limiting plates and abuts against them.

[0020] According to the above technical means, the handle can remain stable in the arrangement direction of the two first limiting plates under the restriction of the two first limiting plates, and will not shake.

[0021] In one possible implementation, the first limiting plate includes a first limiting portion and a second limiting portion connected to each other. The two first limiting portions are disposed at a distance from each other, and the two second limiting portions are also disposed at a distance from each other. The distance between the two first limiting portions is greater than the distance 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 a snap-fit ​​assembly. One end of the second connecting portion is connected to the other end of the first connecting portion, and the extending direction of the second connecting portion intersects the extending 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 the space between the two second limiting portions and abuts against the two second limiting portions.

[0022] According to the above-mentioned technical means, a stepped locking space is formed along the arrangement direction of the first and second limiting parts. 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, thus enabling more stable operation.

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

[0024] According to the above technical means, the protrusion can further restrict the swaying of the handle in the direction perpendicular to the arrangement of the two first limiting plates, that is, restrict the handle from swaying upwards as a whole, thus ensuring the stability of the handle.

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

[0026] According to the above-described technical means, by setting a fixing plate, the first limiting plate, the second limiting plate, and the mounting component can be connected to each other. During disassembly, the first limiting plate, the second limiting plate, and the mounting component can be directly removed from the fixing plate, which is convenient and easy to implement. Of course, in some other embodiments, the first limiting plate and the second limiting plate can also be directly connected to the mounting component.

[0027] In one possible implementation, the mounting plate includes a first fixing portion. The first fixing portion is located on the 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 passes through the first fastener and is threadedly connected to the first fastener.

[0028] According to the above-mentioned technical means, when connecting the first mounting plate and the second mounting plate, the mounting component and the fixing component can also be connected using the first fastener and the second fastener. In this case, the connection between the mounting component and the fixing component can be achieved without setting up additional connecting parts or connecting structures, making the connection convenient and easy to implement, and the structure relatively simple.

[0029] In one possible implementation, the fixing plate further includes a second fixing part. The second fixing part is connected to the first fixing part and is disposed intersecting with the first fixing part, located on the side of the second limiting plate away from the first limiting plate. The first limiting plate has an abutment portion formed at the end near the second limiting plate. The seat lock also includes a third fastener. The third fastener passes through the second limiting plate and the second fixing part, extends into the abutment portion, and is threadedly connected to the abutment portion.

[0030] According to the above technical means, since the third fastener penetrates through the second limiting plate and the second fixing part, the fixing plate and the second limiting plate can be connected together. Since the third fastener also extends into the abutment part and is threadedly connected to it, the third fastener can be connected to the first limiting plate. Thus, through the cooperation of the third fastener and the abutment part, the fixing member can be connected and installed together with the first limiting plate and the second limiting plate.

[0031] In one possible implementation, the snap-fit ​​assembly includes a resilient member, a first snap-fit ​​member, and a second snap-fit ​​member. One end of the resilient member is connected to a mounting member. The first snap-fit ​​member is rotatably connected to the mounting member. A peripheral wall of the first snap-fit ​​member is connected to the other end of the resilient member, and a hook is formed on the peripheral wall. The hook is used to engage with a seat cushion latch. The second snap-fit ​​member is rotatably connected to the mounting member, and its peripheral wall is connected to a handle. A portion of the second snap-fit ​​member abuts against the peripheral wall of the first snap-fit ​​member to restrict the rotation of the first snap-fit ​​member, and is also used to separate from the peripheral wall of the first snap-fit ​​member when actuated by the handle.

[0032] According to the above-mentioned technical means, the first locking member can rotate under the action of the elastic member, thereby causing the hook of the first locking member to separate from or engage with the seat cushion's latch. When the user operates the handle, the second locking member can rotate, thereby causing the second locking member to separate from the peripheral wall of the first locking member. In this way, the first locking member can achieve engagement or disengagement with the seat cushion under the action of the elastic member.

[0033] On the other hand, embodiments of this application provide a seat, including any of the above-mentioned seat cushion locks.

[0034] Since the seat provided in this application embodiment 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, it will not be described again here.

[0035] In another aspect, embodiments of this application provide a vehicle including the aforementioned seat.

[0036] Since the vehicle provided in this application includes the aforementioned seat, it can solve the same technical problems as the aforementioned seat and achieve the same technical effects, it will not be described again here. Attached Figure Description

Detailed Implementation

[0058] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0059] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0060] As people's living standards improve, cars have gradually become their primary means of transportation. To increase the usable space in the trunk, some cars feature rear seat cushions that can be folded forward.

[0061] Because the seat cushion can flip forward, in some unexpected situations, the car seat cushion may be passively flipped forward, thereby affecting passenger safety. Based on this, this application provides a vehicle. This application does not specifically limit the type of vehicle; for example, the vehicle provided in this application can be an electric vehicle, a hybrid electric vehicle, or a solar-powered vehicle, etc.

[0062] To achieve the basic functions of a car, the vehicle may include components such as a body, chassis, powertrain, and electrical system.

[0063] The vehicle body may include a frame, doors, and windows. The frame forms the overall external shape of the vehicle and creates the passenger space. Doors can be rotatably connected to the frame, allowing the interior of the passenger space to be opened or closed. Windows can be mounted on the doors or the frame, providing passengers with a view of the outside environment.

[0064] The chassis may include components such as the transmission system and the drive system. The drive system drives the wheels to rotate. Depending on the drive method, drive systems can be classified as front-wheel drive, rear-wheel drive, and four-wheel drive. The transmission system transmits power generated by the engine to the wheels.

[0065] A powertrain provides power to a vehicle, enabling it to perform basic driving functions. The composition of the powertrain varies depending on the type of vehicle. For example, when the vehicle is an electric vehicle, the powertrain may include an electric motor.

[0066] To supply power to electrical components such as electric motors, the vehicle provided in this application embodiment also includes a battery system. The battery system may include a battery pack, which can be used to provide electrical energy. The battery pack can be electrically connected to the vehicle's electrical components. In this way, the electrical energy from the battery pack can be transferred to the vehicle's electrical components to provide power.

[0067] Furthermore, for user comfort, the vehicle provided in this application embodiment also includes seats. For example... Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a seat 100 provided in an embodiment of this application. The seat 100 may include a first seat 10 and a second seat 20 arranged side by side. The seat 100 can be installed on a carpet assembly 30 in the vehicle cabin. The first seat 10 and the second seat 20 can be 40 / 60 split seats 100. For example, the first seat 10 can be a 60 / 60 split seat 100, and the second seat 20 can be a 40 / 40 split seat 100.

[0068] Continue to refer to Figure 1 The first seat 10 may include a first backrest 11 and a first seat cushion 12. The second seat 20 may include a second backrest 21 and a second seat 20. The first backrest 11 and the first seat cushion 12 are rotatably connected to the vehicle body. Thus, both the first backrest 11 and the first seat cushion 12 can rotate to increase the luggage storage space at the rear of the vehicle. For example, the first seat cushion 12 can be folded forward by rotation, and the first backrest 11 can also be folded forward by rotation to maximize luggage storage space.

[0069] Understandably, the connection of the second seat 20 can be similar to that of the first seat 10. Specifically, 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. Both the second backrest 21 and the second seat cushion 22 can be folded forward by rotating.

[0070] It is understood that the specific structure of the seat 100 provided in this application embodiment can be designed according to actual conditions. In some embodiments, such as Figure 2 As shown, Figure 2 for Figure 1 The exploded view of the first cushion 12 shown indicates that the first cushion 12 may include a cushion frame 121, a cushion cover 122, and a cushion foam 123. The cushion frame 121 may be made of metal wire, forming the basic skeletal shape of the cushion. For example, the cushion frame 121 may be made of steel wire. The diameter of the steel wire can be selected according to the actual situation. For example, the diameter of the steel wire may be 5mm. Of course, the diameter of the steel wire can also be other values, and the specific design can be based on the actual situation; this is only an example for illustration.

[0071] The seat cushion foam 123 can be wrapped around the seat cushion frame 121 to provide elasticity to the seat cushion and improve passenger comfort. For example, when making the seat cushion foam 123, the foam can be directly foamed on the seat cushion frame 121, so that the seat cushion frame 121 is directly set on the seat cushion foam 123 during the manufacturing process of the seat cushion foam 123.

[0072] The seat cover 122 can be fitted over the seat foam 123, covering it completely and preventing it from being exposed, thus improving the overall aesthetics of the seat. The seat cover 122 can be assembled into a single unit using Velcro or C-shaped fasteners.

[0073] To ensure the stable setting of the seat cushion, such as Figure 1 and Figure 2 As shown, the seat 100 provided in this embodiment may further include a seat cushion lock 40. The seat cushion lock 40 can be installed on the seat cushion. For example, as... Figure 1 As shown, the seat lock 40 can be located under the seat. The seat lock 40 can be used to lock or unlock the seat's rotation, preventing it from rotating unnecessarily and improving vehicle safety.

[0074] like Figure 2 As shown, the seat 100 may also include a flipping mechanism 50, which can be connected to the seat cushion. The flipping mechanism 50 is also connected to the vehicle body. The flipping mechanism 50 is used to flip the seat cushion. A latch 53 may be formed on the flipping mechanism 50. A seat cushion lock 40 can engage with the latch 53. In this way, the seat cushion lock 40 and the latch can be relatively fixed, thereby securing the seat cushion. When the seat cushion lock 40 is separated from the latch 53, the user can flip the seat cushion by operation.

[0075] Of course, in other embodiments, the aforementioned latch 53 can also be formed on the vehicle body. In this way, the seat lock 40 engages with the latch 53. The seat lock 40 and the latch can be relatively fixed, thereby fixing the seat lock 40 to the vehicle body and securing the seat.

[0076] To achieve the installation of the flipping mechanism 50 and the seat lock 40 on the seat, such as Figure 2 As shown, the first seat cushion 12 may also include multiple mounting plates 124. The seat cushion lock 40 and the flipping mechanism 50 may be connected to the mounting plates 124 to achieve connection with the seat cushion.

[0077] Understandable, Figure 1 The second cushion 22 shown can also be equipped with Figure 2 The relevant structures shown in this application are illustrated using the structure at the first cushion 12 as an example.

[0078] The following is a further introduction to the aforementioned seat lock 40 and flipping mechanism 50.

[0079] First, the cushion lock 40 provided in the embodiments of this application will be further described. For example... Figure 3 and Figure 4 As shown, Figure 3 This is an exploded view of a cushion lock 40 provided in an embodiment of this application. Figure 4 for Figure 3 The diagram shows a partial sectional view of the seat lock 40 during assembly. The seat lock 40 may include a mounting member 41, a snap-fit ​​assembly 42, and a handle 43. The mounting member 41 has an internal mounting cavity and a first opening and a second opening communicating with the mounting cavity. Thus, the interior of the mounting member 41 provides mounting space for the snap-fit ​​assembly 42 and the handle 43, while also providing a protective function.

[0080] The snap-fit ​​assembly 42 is located within the mounting cavity and is movably connected to it. A portion of the snap-fit ​​assembly 42 is used to engage or disengage with the seat cushion's latch 53 through the first opening. Thus, because the snap-fit ​​assembly 42 is located within the mounting cavity, it will not be exposed even when the seat cushion is flipped over. The mounting member 41 provides protection for the snap-fit ​​assembly 42, preventing the user from directly touching it and thus avoiding damage, thereby ensuring the normal operation of the seat cushion lock 40. Simultaneously, the snap-fit ​​assembly 42 can also engage or disengage with the latch 53 through the first opening. For example, as... Figure 4 As shown, the snap-fit ​​assembly 42 can engage with the latch 53 through the opening formed below the mounting piece 41. Figure 2 ) to engage or disengage.

[0081] A portion of the handle 43 passes through the second opening, extends into the mounting cavity, and connects to the locking assembly 42. This connection drives the locking assembly 42 to move, thereby disengaging it from the seat cushion's latch 53. Thus, when operating the handle 43, the user can move the locking assembly 42, separating it from the latch 53 and adjusting the seat cushion's position. For example,... Figure 3 As shown, the handle 43 can be inserted into the mounting cavity through the opening at the front of the mounting member 41.

[0082] Based on this, the seat lock 40 provided in this application embodiment has an installation cavity inside the mounting member 41. The interior of the mounting member 41 provides installation space for the snap-fit ​​component 42 and the handle 43, while also providing protection. The first opening allows the snap-fit ​​component 42 to easily snap into or separate from the seat's latch 53. The second opening allows the handle 43 to easily extend into the installation cavity and connect with the snap-fit ​​component 42, thereby driving the snap-fit ​​component 42 to move and achieve snap-fit ​​or separation between the snap-fit ​​component 42 and the latch 53. Simultaneously, since the snap-fit ​​component 42 is located inside the installation cavity, it will not be exposed after the seat is flipped over. The mounting member 41 protects the snap-fit ​​component 42, preventing the user from directly touching it and avoiding damage to it, thus ensuring the normal use of the seat lock 40.

[0083] In some embodiments, such as Figure 3 As shown, the mounting component 41 may include a first mounting plate 411, a second mounting plate 412, and a connector 413. The second mounting plate 412 is disposed at a distance from the first mounting plate 411. The gap between the first mounting plate 411 and the second mounting plate 412 forms a mounting cavity, and also forms a first opening and a second opening.

[0084] Thus, when the snap-fit ​​assembly 42 is positioned 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 snap-fit ​​assembly 42 from both sides. Since the mounting component 41 is a plate-shaped assembly, its structure is simple and easier to manufacture.

[0085] Meanwhile, the connector 413 is detachably connected to the first mounting plate 411 and the second mounting plate 412. Thus, when the snap-fit ​​assembly 42 needs to be disassembled for maintenance, the user can separate the first mounting plate 411 and the second mounting plate 412 by removing the connector 413, thereby allowing the snap-fit ​​assembly 42 to be removed. The operation is simple, convenient, and easy to implement.

[0086] Of course, the first mounting plate 411 and the second mounting plate 412 can 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 can be directly snapped together. In this case, the first mounting plate 411 and the second mounting plate 412 can each be provided with a snap-fit ​​structure to achieve the snap-fit ​​between the two. In this way, the first mounting plate 411 and the second mounting plate 412 are directly connected without the need for a connector 413 for connection.

[0087] In some embodiments, such as Figure 3As shown, at least one first bend 4111 is formed on the periphery of the first mounting plate 411. The first bend 4111 bends toward the side where the first mounting plate 411 and the second mounting plate 412 are close to each other. Thus, as... Figure 3 As shown, the first bend 4111 can also engage with the snap-fit ​​assembly 42 ( Figure 4 It serves as a protective measure to prevent the snap-fit ​​component 42 from being impacted from the location of the first bend 4111.

[0088] Similarly, in some embodiments, at least one second bend (not shown) is formed on the periphery of the second mounting plate 412. The second bend bends 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 bend can also protect the snap-fit ​​assembly 42 from impact from the location of the second bend.

[0089] In some embodiments, such as Figure 3 As shown, the connector 413 includes a first fastener 4131 and a second fastener 4132. The first fastener 4131 passes through the first mounting plate 411 and the second mounting plate 412. The second fastener 4132 passes through the first fastener 4131 and is threadedly connected to it. Thus, the threaded connection between the first fastener 4131 and the second fastener 4132 securely connects the first mounting plate 411 and the second mounting plate 412 together. For example, the first fastener 4131 can be a bolt, and the second fastener 4132 can be a nut.

[0090] Of course, the connector 413 can also have other components. For example, in some other embodiments, the connector 413 may consist only of the first fastener 4131. In this case, the first fastener 4131 can pass through 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 can also be firmly connected together by the first fastener 4131.

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

[0092] Because the limiting component 44 forms a limiting space, a portion of the handle 43 outside the mounting cavity passes through this limiting space. Thus, a portion of the handle 43 is located within the limiting space. Simultaneously, the limiting component 44 restricts the handle 43 from wobbling in a direction parallel to the plane containing the second opening. In this way, the handle 43 can be kept stable by the limiting component 44, making it less prone to wobbling as described above, resulting in greater stability when operating the handle 43 and better enabling the locking component 42 to move.

[0093] Of course, in some other embodiments, the seat lock 40 may not have a limiting component 44. In this case, corresponding limiting structures can be provided on the first mounting plate 411 and the second mounting plate 412 to restrict the movement of the handle 43, so that the handle 43 can be more stable and facilitate the movement of the locking component 42.

[0094] like Figure 3 As shown, the limiting component 44 may include a first limiting member 441. For example... Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the structure of a first limiting member 441 provided in an embodiment of this application. Figure 6 for Figure 5 The diagram shows the structure of the first limiting member 441 from another angle. The first limiting member 441 includes two first limiting plates 4411 and a connecting portion 4412. The two first limiting plates 4411 are arranged at a distance from each other. The connecting portion 4412 is located between the two first limiting plates 4411 and is connected to the two first limiting plates 4411.

[0095] A portion of the handle 43 is located between and abuts against the two first limiting plates 4411. This allows the handle 43 to remain stable and prevent wobbling under the constraint of the two first limiting plates 4411 in their arrangement direction. For example, when the limiting component 44 is installed on the mounting member 41, the arrangement direction of the two first limiting 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, such as Figure 5 and Figure 6 As shown, the first limiting plate 4411 includes a first limiting portion 4413 and a second limiting portion 4414 connected to each other. The two first limiting portions 4413 are arranged with a relative gap, and the two second limiting portions 4414 are also arranged with a relative gap. The distance between the two first limiting portions 4413 is greater than the distance between the two second limiting portions 4414. Therefore, as... Figure 7 and Figure 8 As shown, Figure 7 for Figure 5 The top view of the first limiting member 441 shown. Figure 8 for Figure 5 The front view of the first limiting member 441 shown shows that a stepped snap-fit ​​space is formed along the arrangement direction of the first limiting part 4413 and the second limiting part 4414.

[0097] At the same time, such as 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 snap-fit ​​assembly 42. Figure 4 The second connecting part 4412432 is connected to the other end of the first connecting part 4412431, and the extending direction of the second connecting part 4412432 intersects the extending direction of the first connecting part 4412431.

[0098] In this configuration, a portion of the first connecting part 4412431 is located between the two first limiting parts 4413, and the second connecting part 4412432 passes between the two second limiting parts 4414 and abuts against the two second limiting parts 4414. Thus, as... Figure 9 As shown, Figure 9 This is a structural diagram of the assembly of handle 43 and limit component 44. The second connecting part 4412432 remains stable under the abutment of the second limit parts 4414 on both sides, and will not shake along the arrangement direction of the two second limit parts 4414, so that the operation can be more stable.

[0099] In some embodiments, such as Figure 3 As shown, the limiting assembly 44 also includes a second limiting plate 442. It is located on one side of the two first limiting plates 4411, perpendicular to the arrangement direction of the two first limiting plates 4411. Figure 10 and Figure 11 As shown, Figure 10 This is a schematic diagram of the structure of a second limiting plate 442 provided in an embodiment of this application. Figure 11 for Figure 10 The diagram shows the second limiting plate 442 from another angle, with a protrusion 4421 formed on the second limiting plate 442. (Combined with...) Figure 9 The second limiting plate 442 has the aforementioned protrusion 4421 on the side near 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 direction perpendicular to the arrangement of the two first limiting plates 4411, that is, limit the handle 43 from shaking upward as a whole, and ensure the stability of the handle 43.

[0101] like Figure 3As shown, in some embodiments, the seat lock 40 further 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. Thus, by providing the fixing plate 45, the first limiting plate 4411, the second limiting plate 442, and the mounting member 41 can be interconnected. During disassembly, the first limiting plate 4411, the second limiting plate 442, and the mounting member 41 can be directly removed from the fixing plate 45, making the operation convenient 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 the side of the second mounting plate 412 away from the first mounting plate 411. In this case, a first fastener 4131 passes through the first mounting plate 411, the second mounting plate 412, and the first fixing portion 451. A second fastener 4132 passes through the first fastener 4131 and is threadedly connected to the first fastener 4131.

[0103] Therefore, by using the first fastener 4131 and the second fastener 4132, while connecting the first mounting plate 411 and the second mounting plate 412, the mounting component 41 can also be connected to the fixing component. In this case, the connection between the mounting component 41 and the fixing component can be achieved without setting up an additional connecting part 4412 or a connecting structure, making the connection convenient and easy to implement, and the structure 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] Furthermore, by way of example, there can be multiple first fasteners 4131 and second fasteners 4132. A more secure fixation can be achieved by fastening with multiple first fasteners 4131 and second fasteners 4132.

[0105] It is understandable that, in order to achieve the penetration of the first fastener 4131, as described above, Figure 3 As shown, the first fixing part 451, the first mounting plate 411 and the second mounting plate 412 may be provided with corresponding clearance holes 4422 so that the first fastener 4131 can pass through the first fixing part 451, the first mounting plate 411 and the second mounting plate 412.

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

[0107] Among them, such as Figure 13 As shown, Figure 13 for Figure 5 The side view of the first limiting member 441 shown, combined with Figure 3 The first limiting plate 4411 has an abutment portion 4415 formed at one end near the second limiting plate 442. The seat lock 40 also includes a third fastener 46. The third fastener 46 passes through the second limiting plate 442 and the second fixing portion 452, extends into the abutment portion 4415, and is threadedly connected to the abutment portion 4415.

[0108] Since the third fastener 46 passes through the second limiting plate 442 and the second fixing part 452, the fixing plate 45 and the second limiting plate 442 can be connected together. Since the third fastener 46 also extends into the abutment part 4415 and is threadedly connected to it, the third fastener 46 can be connected to the first limiting plate 4411. Thus, through the cooperation of the third fastener 46 and the abutment part 4415, the fixing member can be connected and installed together with the first limiting plate 4411 and the second limiting plate 442. For example, the third fastener 46 can be a bolt.

[0109] For example, such as Figure 6 As shown, the first limiting portion 4413 is plate-shaped, and the end of the first limiting portion 4413 away from the second limiting portion 4414 is bent, forming the aforementioned abutment portion 4415. Meanwhile, as... Figure 12 As shown, Figure 12 for Figure 5 The side view of the first limiting member 441 shown shows that the abutment part 4415 has a certain length and is a boss structure so that the third fastener 46 can be better inserted for threaded connection.

[0110] Furthermore, for example, the number of third fasteners 46 and abutments can both be multiple.

[0111] In addition, such as Figure 3 As shown, the seat lock 40 also includes a fourth fastener 47. The fourth fastener 47 can pass through the second fixing part 452 and is attached to the seat (e.g., Figure 1 The first seat cushion 12) is threaded. Thus, the entire seat cushion lock 40 can be connected via the fourth fastener 47, which is convenient and easy to implement. For example, the fourth fastener 47 can be a bolt. Furthermore, the number of fourth fasteners 47 can also be multiple.

[0112] like Figure 13 As shown, Figure 13 for Figure 10 The top view of the second limiting plate 442 shown indicates that the second limiting plate 442 may have a clearance hole 4422. Thus, the third fastener 46 ( Figure 3 It can pass directly through the clearance hole 4422, making installation more convenient.

[0113] In some embodiments, such as Figure 13 As shown, combined with Figure 14 as well as Figure 15 , Figure 14 for Figure 10 The front view of the second limiting plate 442 shown. Figure 15 for Figure 10 The side view of the second limiting plate 442 shown illustrates that the protrusion 4421 on the second limiting plate 442 can form a recess on the other side, which can be directly formed by pressing the second limiting plate 442. Alternatively, in some embodiments, the protrusion 4421 can also be formed directly by adding material to the surface of one side of the second limiting plate 442. In this case, the surface of the second limiting plate 442 without the protrusion 4421 can be a flat surface.

[0114] In order to enable the snap-fit ​​component 42 to engage or disengage with the seat cushion's latch 53, in some embodiments, such as Figure 4 As shown, the snap-fit ​​assembly 42 may include an elastic member 421, a first snap-fit ​​member 422, and a second snap-fit ​​member 423. One end of the elastic member 421 is connected to the mounting member 41. The first snap-fit ​​member 422 is rotatably connected to the mounting member 41. The peripheral wall of the first snap-fit ​​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 snap into the seat cushion's latch 53.

[0115] In this way, the first locking member 422 can rotate under the action of the elastic member 421, thereby causing the hook 4221 of the first locking member 422 to separate from or engage with the seat cushion's latch 53. For example, Figure 4 As shown, the first latching member 422 can rotate clockwise under the action of the elastic member 421. At this time, as the first latching member 422 rotates, the opening of the latch 4221 gradually faces downward, and the latch 4221 can be separated from the seat cushion's latch 53.

[0116] In addition, such as Figure 4 As shown, to facilitate the connection between the elastic member 421 and the first snap-fit ​​member 422, a hook 4222 is formed on the peripheral wall of the first snap-fit ​​member 422. The hook 4222 can be attached to one end of the elastic member 421. For example, the elastic member 421 can be a spring.

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

[0118] Therefore, when the user operates the handle 43, the second latching member 423 can rotate, thereby separating the second latching member 423 from the peripheral wall of the first latching member 422. In this way, the first latching member 422 can engage or disengage from the seat cushion under the action of the elastic member 421. For example, as shown... Figure 4 As shown, when the user operates the handle 43 and rotates it counterclockwise, the second locking member 423 rotates counterclockwise. At this time, as the second locking member 423 rotates counterclockwise, the first locking member 422 and the second locking member 423 will separate from each other. Then, the first locking member 422 can rotate clockwise under the action of the elastic member 421, so that the opening of the hook 4221 faces the same direction, and the hook 4221 separates from the seat cushion's latch 53.

[0119] At the same time, combined Figure 4 and Figure 9 As shown, when the user operates the handle 43 using the grip part 433, the first limiting plate 4411 and the second limiting plate 442 can limit the shaking of the handle 43, so that the handle 43 can be better positioned according to the user's position. Figure 4 The tilting of the indicated direction causes the second locking member 423 to move, thereby separating the second locking member 423 from the first locking member 422. When the user returns the seat cushion to its original position, the downward pressure of the seat cushion causes the latch 53 and the hook 4221 of the first locking member 422 to interact, causing the first locking member 422 to move counterclockwise until it engages with the second locking member 423. This allows the second locking member 423 to restrict the clockwise movement of the first locking member 422, thus completing the engagement between the hook 4221 and the latch 53.

[0120] Furthermore, the elastic element 421 can also be connected to the second latching element 423 to drive the second latching element 423 to reset. In this way, the second latching element 423 can be reset through the elastic element 421.

[0121] Of course, the snap-fit ​​component 42 provided in this application embodiment may also have other structures and compositions. The specific design can be made according to the actual situation, as long as the snap-fit ​​component 42 can be snapped or separated from the seat cushion buckle 53. This is only described as an example.

[0122] For example, in some embodiments, the snap-fit ​​assembly 42 may consist only of a first snap-fit ​​member 422 and a handle 43. In this case, the handle 43 can be directly connected to the peripheral wall of the first snap-fit ​​member 422. Thus, when the user operates the handle 43, it can directly drive the first snap-fit ​​member 422 to move, thereby allowing the hook 4221 of the first snap-fit ​​member 422 to engage or disengage with the seat cushion's latch 53.

[0123] To achieve seat cushion flipping, in some embodiments, the flipping mechanism 50 may include a first flipping component and a second flipping component. The first flipping component may be connected to the vehicle body. One end of the second flipping component may be rotatably connected to the first flipping mechanism 50, and the other end may be rotatably connected to the seat cushion. Thus, through the first and second flipping components, the seat cushion can flip around the two ends of the second flipping mechanism 50 as rotation centers, thereby achieving multiple flips of the seat cushion.

[0124] like Figure 16 As shown, Figure 16 The exploded view of a flipping mechanism 50 provided in this application embodiment shows that the first flipping assembly may include two vehicle body connecting brackets 51, two first hinges 54, and a first connecting rod 52. Each end of the first connecting rod 52 is connected to one vehicle body connecting bracket 51, allowing the two vehicle body connecting brackets 51 to be interconnected. A latch 53 may be formed on the first connecting rod 52.

[0125] The vehicle body mounting bracket can be connected to the vehicle body. For example, the vehicle body mounting bracket 51 can be connected to the vehicle body by bolts. A vehicle body mounting bracket 51 can be equipped with a first hinge 54. In this way, the vehicle body mounting bracket can be rotatably connected to other components via the first hinge 54.

[0126] Continue to refer to Figure 16 The second flipping assembly may include two flipping support arms 55. One end of each of the two flipping support arms 55 is rotatably connected to a first hinge 54. Thus, the two flipping support arms 55 can rotate relative to the first flipping mechanism 50. Simultaneously, the second flipping assembly also includes a second connecting rod 56. Both ends of the second connecting rod 56 are respectively connected to the other ends of the two flipping support arms 55. Thus, the two flipping support arms 55 can be interconnected via the second connecting rod 56.

[0127] like Figure 16As shown, the second flip assembly also includes two second hinges 57 and two seat cushion mounting bases 58. The two second hinges 57 are respectively mounted at the other end of the two flip support arms 55. Each of the two seat cushion mounting bases 58 can be rotatably connected to one of the second hinges 57. Thus, the seat cushion mounting base can rotate relative to the second hinge 57. Simultaneously, the seat cushion mounting base 58 can be connected to the seat cushion. Thus, the seat cushion can rotate relative to the second hinge 57.

[0128] Among them, such as Figure 16 As shown, the second flip assembly may further include a fifth fastener 59, which can be connected to the seat mounting base 58 and the seat. Thus, the seat mounting base 58 and the seat can be interconnected via the fifth fastener 59. For example, the fifth fastener 59 may be a bolt.

[0129] based on Figure 16 The flipping mechanism 50 shown is as follows: Figure 17 and Figure 18 As shown, Figure 17 This is a structural diagram of the seat cushion in its normal state. Figure 18 This is a structural diagram of the seat cushion in the forward-folding position, as shown below. Figure 17 As shown, when the seat cushion is in its normal position, it can rotate around the first hinge 54 and the second hinge 57 respectively. The seat cushion can rotate counterclockwise around the first hinge 54 to flip forward, and simultaneously rotate clockwise around the second hinge 57. After flipping, the seat cushion's position is as follows. Figure 18 As shown.

[0130] Therefore, as Figure 19 As shown, Figure 19 This is a cross-sectional view of the first seat cushion 12 provided in an embodiment of this application. The user can unlock the seat cushion using the handle 43 of the seat cushion lock 40. At this time, the seat cushion can rotate under the action of the flipping mechanism 50, causing the seat cushion to rotate around the first hinge 54 and the second hinge 57, thereby achieving the forward flipping of the seat cushion.

[0131] In addition, such as Figure 19 As shown, the flipping mechanism 50 and the mounting component 41 are all located at the front of the bottom of the first seat cushion 12, which can provide good support for the first seat cushion 12. In the event of a collision, it can effectively prevent the human body from moving forward and downward, thus improving the anti-submersion performance of the seat.

[0132] Of course, it is understood that the second flipping component provided in this application embodiment may also have other structural components, as long as the seat cushion can be flipped. The specific design can be made according to the actual situation. This is only used as an example for illustration.

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