Detailed ways

In order to understand the above objects, features and advantages of the present disclosure more clearly, the solutions of the present disclosure will be further described below. It should be noted that, as long as there is no conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

Many specific details are set forth in the following description to fully understand the present disclosure, but the present disclosure can also be implemented in other ways different from those described here; obviously, the embodiments in the description are only part of the embodiments of the present disclosure, and Not all examples.

Embodiment 1

For existing structural assemblies that are installed on the mounting surface, such as child safety seats installed in vehicles, since they need to be fixed relative to the seat and the vehicle, they are usually set at an angle that cannot be adjusted, resulting in use It is impossible to change the orientation or angle of the structure according to the actual sitting and lying situation, which reduces the flexibility of use and the comfort of riding.

In view of the above defects, this embodiment provides a lifting mechanism, a seat structure assembly and a vehicle. The lifting mechanism is provided to adjust the seat, thus solving the problem of low flexibility in use of traditional seats. The structural settings of the lifting mechanism, seat structure assembly and vehicle are as follows:

As shown in Figures 1-6, this embodiment provides a lifting mechanism 4, which includes a support component, a connection component and a lifting component. The lifting component is installed between the support component and the connection component. One end of the lifting component is rotationally connected to the connection component. , the other end of the lifting component is connected to the supporting component for lifting.

In this embodiment, the lifting mechanism 4 can be applied to a child safety seat used inside a vehicle. Of course, in other embodiments, the lifting mechanism 4 can also be applied to other similar structures to perform a lifting function.

When applied to a child safety seat, because the end of the lifting component of the lifting mechanism 4 away from the mounting base 2 of the seat body 1 can move relative to the mounting base 2, and because the lifting mechanism 4 is located between the mounting base 2 and the seat between the chair bodies 1. Therefore, the lifting mechanism 4 can drive the seat body 1 to move up and down. In this case, the lifting mechanism 4 can drive at least part of the seat body 1 to move up and down. When the displacement at the position is different, the seat body 1 will tilt.

When the lifting mechanism 4 is installed on a child safety seat, the seat body 1 is connected to the floor of the vehicle through the connecting assembly 3 . The connecting component 3 can include a connecting piece 31 connected to the seat body 1, and a connecting piece 31 rotatably connected to the seat body 1. The engaging piece 32 is connected, and a connecting bayonet is formed between the engaging piece 32 and the connecting piece 31. The floor of the vehicle is preset with hooks or ropes for installing ordinary seats of the vehicle. The child safety seat can be connected through the connecting piece 32. The bayonet is connected with the hook or rope to achieve assembly on the floor of the vehicle. Among them, the engaging member 32 is rotatably connected to the connecting member 31, and a connection bayonet is formed between the engaging member 32 and the connecting member 31. Therefore, when the engaging member 32 rotates relative to the connecting member 31, the engaging member 32 is locked. The opening size of the connection bayonet formed between the position of the closing member 32 that is far away from the rotational connection with the connecting member 31 and the connecting member 31 can be changed. Since the child safety seat is connected to the floor of the vehicle through the above-mentioned connection bayonet, it can be understood that when the size of the connection bayonet is smaller than the opening size required to realize the snap connection, the child safety seat The child safety seat is snap-fitted with the vehicle's floor surface through the connecting component 3. When the size of the connection bayonet is adjusted to be larger than the opening size required for snap-in, the child safety seat can be disassembled relative to the vehicle's floor surface.

The lifting assembly of the lifting mechanism 4 includes at least two lifting links 41. All the lifting links 41 are arranged in sequence along the direction from the first mounting part toward the second mounting part, and the ends of two adjacent lifting links 41 are close to each other. Articulated connection. One end of the lifting link 41 at the extreme end is rotatably connected to the installation base 2 , and the other end of the other lifting link 41 at the extreme end is rotatably connected to the bottom of the seat body 1 . Through the hinged connection, the lift link 41 changes the angle between it and the installation base 2, thereby changing the height of the end of the lift link 41 away from the installation base 2, so as to drive the seat body 1 to adjust the height. , this setting method has a simple and reliable structure and is easy to operate.

In addition, in order to improve the stability of the lifting process, in this embodiment, the number of lifting mechanisms 4 is set to at least two, and the at least two lifting mechanisms 4 are arranged on both sides of the bottom of the seat body 1 in the width direction. Each has at least one. Regarding the vehicle structure, the width direction of the seat body 1 is usually the lateral extension direction of the seat. The lateral extension direction refers to the width direction of the vehicle, that is, perpendicular to the direction of travel of the vehicle. Therefore, the seat body 1 The front-to-back direction is perpendicular to the width direction of the seat body 1. All the lifting mechanisms 4 are symmetrically arranged on both sides of the bottom of the seat body 1 with the front-to-back direction of the seat body 1 as the central axis. In this embodiment, they are A lifting mechanism 4 is provided on both sides of the front bottom of the seat body 1, as shown in Figure 3 for details.

In order to minimize the number of structures that need to be operated, in this embodiment, the bottom rear side of the seat body 1 and the mounting base 2 can be hinged, and the bottom front side of the seat body 1 and the mounting base 2 are connected through a lifting mechanism. 4 connections. That is to say, the front side of the seat body 1 is adjusted up and down through the lifting mechanism 4, and the other position is only hinged with the installation base 2 to adapt to angular orientations at different heights. Of course, in other embodiments, the lifting mechanism 4 can also be provided on the bottom front side of the seat body 1 and the bottom rear side of the seat body 1, so that not only the angle can be adjusted, but also the front and rear sides can be adjusted. The lifting mechanisms 4 on both sides are used to adjust the overall height of the child safety seat.

When assembling the lifting mechanism 4 with the seat body 1 and the mounting base 2, the seat body 1 is disposed on the support component and the mounting base 2 is disposed on the connecting component. In some specific embodiments, the support component is a lifting support plate 521. The lifting support plate 521 can further ensure the stability of the child safety seat during use. One side of the lifting support plate is provided with a first connection portion for rotationally connecting with the lifting assembly, and the first connection portion is used for connecting with the lifting assembly to oppose each other. When the lifting component rotates, a second connecting portion is provided on the other side of the lifting support plate. When the lifting mechanism is used in a child safety seat, the second connection part is specifically a plurality of fixing holes provided on the lifting support plate 521 .

In some specific embodiments, the seat body 1 is provided with a connecting hole at a position corresponding to the fixing hole, and fasteners are inserted into the fixing hole and the connecting hole to realize the connection between the seat body 1 and the lifting support plate 521 . connections between. The connecting component is two connecting ribs 43 provided at positions corresponding to the lifting link 41. One side of the connecting rib is provided with a third connecting portion for rotational connection with the lifting component, and the other side of the connecting rib is provided with a fourth connection. department. The third connection part is the support hole provided on the connecting rib. Through the support hole provided on the connecting rib 43, the hinge rotation point of the lifting link 41 and the hinge rotation point of the seat body 1 are respectively formed. At the same time, the connecting rib 43 The fourth connecting portion provided on the other side is also convenient for connecting with the mounting base 2 .

In addition, in some embodiments, a rotating assembly 5 may also be provided between the mounting base 2 and the seat body 1, as shown in Figures 4 and 5 for details. In some specific embodiments, the seat body 1 is rotationally connected to the mounting base 2 through the rotating assembly 5 , and the seat body 1 can rotate relative to the mounting base 2 in a direction perpendicular to the floor surface of the vehicle. Since the seat body 1 is connected to the floor of the vehicle through the mounting base 2, the seat body 1 rotates relative to the mounting base 2 through the rotating assembly 5, that is, the seat body 1 rotates relative to the vehicle. When adjusting the orientation of the seat, the seat body 1 can be adjusted to any position by adjusting the rotating assembly 5 . Among them, the direction perpendicular to the floor surface of the vehicle is usually the vertical direction, and is also the height direction of the seat.

By connecting the seat body 1 to the mounting base 2 through the rotating assembly 5, the seat body 1 can be rotated relative to the mounting base 2, thereby conveniently adjusting the orientation of the child safety seat to any position inside the vehicle. The user in the position can adaptively adjust the direction of the child safety seat to take care of the baby sitting on the child safety seat. The operation method is convenient and the structure is simple.

In some specific embodiments, the rotating assembly 5 includes a first rotating component 51 provided on the seat body 1 and a second rotating component 52 provided on the mounting base 2. The first rotating component 51 is relative to the second rotating component 52. The rotating member 52 is rotatable in a direction perpendicular to the floor surface of the vehicle. Since the structure of the seat body 1 is large and the support area of the mounting base 2 is limited, relative rotation is achieved by providing the first rotating component 51 and the second rotating component 52 to facilitate the driving of the seat body 1, and at the same time It is also convenient to set up the structure for realizing the rotation effect.

On this basis, in order to achieve relative rotation, the rotating assembly 5 can include a rolling bearing, the outer ring of the rolling bearing is arranged on the first rotating part, and the inner ring of the rolling bearing is arranged on the second rotating part. Providing a rolling bearing makes it easier to achieve relative rotation and at the same time ensures the reliability of the connection between the first rotating part and the second rotating part.

Of course, in other embodiments, the opposite arrangement can also be adopted, that is, the bearing outer ring of the rolling bearing is arranged on the second rotating part; the bearing inner ring of the rolling bearing is arranged on the first rotating part, which can also achieve the effect of relative rotation. In addition, in some other embodiments, the relative rotation between the first rotating part and the second rotating part can also be achieved without using rolling bearings. For example, a gear capable of butt transmission can be provided between the two rotating parts. It can also be achieved Effect on rotation.

On the basis of realizing relative rotation between the first rotating part and the second rotating part through the rolling bearing, in this embodiment, a mounting hole 511 can be provided at the middle position of the surface of the first rotating part, and the second rotating part is provided with In the connecting portion opposite to the mounting hole 511, the outer ring of the bearing is arranged in the mounting hole 511, and the connecting portion is connected and fixed with the inner ring of the bearing. Correspondingly, the bearing inner ring is located inside the bearing outer ring, that is, inside the mounting hole 511 , and the connecting portion is further connected and fixed with the bearing inner ring. This arrangement saves more structural space and makes it easier to ensure stability between the seat body 1 and the mounting base 2 during relative rotation. The mounting hole 511 is set at the middle position of the surface of the mounting base 2, which can This prevents the seat body 1 from causing a large deviation during the rotation, and has better adaptability to the relatively narrow space inside the vehicle.

In specific implementation, in order to make it easier for the user to operate and realize automatic control of the seat, the rotating assembly 5 further includes a driving member, and the driving member provides driving force for the rotation of the seat body 1 .

In some specific embodiments, the driving shaft of the driving member can be coaxially arranged and connected with the bearing outer ring or the bearing inner ring, making the rotation movement easier to achieve. When a drive shaft is used to provide driving force, a drive motor can be provided, and the drive shaft is formed by the output shaft of the drive motor. On this basis, a drive button that can be electrically connected to the drive motor can also be provided on the seat body 1 or the installation base 2. By pressing or adjusting the drive button, the rotation of the seat can be realized accordingly. The entire driving part can be fixed with the seat body 1 or the installation base 2 to ensure the stability of operation, and the power of the driving motor can be provided by the vehicle or the built-in power supply of the child safety seat. And because the driving part is directly connected to the bearing outer ring or the bearing inner ring, when the system stops working, the fixed state of the driving part can keep the bearing outer ring or bearing inner ring connected to it also fixed. , thereby realizing the positioning of the rotation position of the rotating component 5 and preventing it from continuing to rotate and affecting its use.

In other embodiments, other driving methods may also be used. For example, the driving shaft of the driving member and the bearing outer ring or the bearing inner ring are drivingly connected through a conveyor belt. That is, the tendency of the rotational motion of the drive shaft is transmitted to the first rotating component 51 or the second rotating component 52 through the conveyor belt, so that they can perform relative rotational motion. This arrangement provides a wider range of installation space for the driver. In some other embodiments, the driving member can also be provided with a driving screw, and the outer ring of the first rotating member 51 or the second rotating member 52 is provided with a butt gear. The driving screw of the driving member is connected to the first rotating member 51 Or the butt gear of the second rotating part 52 is meshed. Transmission through docking gears provides better stability.

In addition, when arranging the rotating assembly 5, the second rotating component 52 can also include a supporting plate. In this arrangement, the second mounting part is located on the top of the first mounting part, that is, the seat body 1 is connected to the supporting plate. , to form a stable support plane to further ensure the stability of the child safety seat during use. In some specific embodiments, in order to improve the support effect, a plurality of reinforcing ribs can be provided on the support plate. The reinforcing ribs are arranged circumferentially along the top of the support plate. The connecting columns 522 can be arranged at the four end corners of the support plate. , to ensure structural strength while ensuring stable support.

When a support plate is provided, several connecting posts 522 can be provided on the top of the support plate, correspondingly, on the seat body 1 A connection hole is provided at the bottom of the seat corresponding to the position of the connection post 522, so that the support plate and the seat body 1 are interconnected and fixed by the connection post 522 passing through the connection hole.

In some embodiments, the second rotating part may further include a mounting platform 512 , which is the mounting base 2 with the connecting assembly 3 at the bottom. Similarly, multiple bottom reinforcement ribs may be provided on the mounting platform 512, and corresponding side reinforcement ribs may be provided on the sides to further ensure structural strength.

In addition, for the connection component 3 of the child safety seat, in some embodiments, in order to make the connection component 3 more convenient for disassembly, assembly and fixation of the seat, the child safety seat may also include a component installed on the seat. The unlocking component on the body 1 is connected to the engaging piece 32, and the engaging piece 32 can rotate relative to the connecting piece 31 driven by the unlocking assembly to adjust the opening size of the connecting bayonet. For details, see Figure 6 Show.

The unlocking component is connected to the connecting component 3 correspondingly, and the unlocking component is also connected to the engaging piece 32, thereby driving the engaging piece 32 to move in a direction away from the connecting piece 31, that is, driving the engaging piece 32 to rotate relative to the connecting piece 31, Thereby changing the opening size of the connection bayonet to make it larger or smaller than the size required to realize the snap connection, thereby changing the state of the child safety seat relative to the vehicle floor. That is to say, by operating the unlocking component, the connection bayonet can be adjusted to achieve disassembly and assembly relative to the installation surface.

During specific implementation, the connection bayonet can be preset to be larger than the opening size required for the bayonet connection, and the child safety seat can be aligned with the corresponding installation position on the vehicle floor. After the alignment is completed, the unlocking component can be operated to rotate the latch member 32 relative to the connecting member 31 until the opening size of the connecting bayonet is smaller than the opening size required to realize the latch connection, thereby allowing the child safety seat to be connected to the connecting member 31 . Connect and secure vehicles. Of course, in other embodiments, an installation chamfer can also be provided at the connection bayonet. That is, when the connection bayonet is aligned with the corresponding installation position of the vehicle, the connection bayonet can be pushed open by abutting force. Then when the alignment is completed, the connection bayonet is automatically tightened, thereby achieving snap-on fixation.

When the child safety seat needs to be disassembled, the unlocking assembly is operated, and the unlocking assembly drives the latch member 32 to move in the direction of making the opening of the connection bayonet larger, usually in the direction of the latch member 32 away from the connector 31 until the connection is made. After the opening size of the bayonet is larger than the opening size required to achieve the bayonet connection, the child safety seat can be directly removed from the floor of the vehicle.

The child safety seat is provided with a connecting component 3, and is snap-connected to the floor of the vehicle through the connection bayonet on the connecting component 3. This snap-in fixing method is simple and fast to operate, and is more convenient to install. Moreover, the child safety seat The unlocking component of the chair can be connected to the engaging piece 32, thereby driving the engaging piece 32 to rotate relative to the connecting piece 31. Since the engaging piece 32 rotates relative to the connecting piece 31, the opening size of the connecting bayonet can be adjusted. To the extent that it can be unlocked from the floor of the vehicle, and after the opening size reaches a level larger than the unlocking level, the child safety seat can be removed directly, thereby realizing that the connecting assembly can be connected by operating the unlocking assembly. 3. Disconnecting from the floor of the vehicle enables quick disassembly of the child safety seat, improving user convenience when loading and unloading.

On the basis of the above, an elastic recovery member may also be provided between the engaging member 32 and the connecting member 31 , and the elastic recovery member can deform along the direction of the second connecting member 31 toward the first connecting member 31 . The elastic recovery member is used to provide a restoring force to the latching member 32. That is, after the latching member 32 rotates relative to the connecting member 31 to a size larger than the opening size required to achieve the latching, the elastic recovery member will continue to provide pulling force for the latching member 32. , so that it can move in the direction of decreasing angle, so that the clamping effect can be continuously guaranteed.

The content provided in this embodiment is an example way to make the child safety seat snap and fix only with the floor surface of the vehicle through the connecting assembly 3, but it does not mean that the child safety seat only has the features provided in this embodiment. One setting is possible. In other embodiments, this kind of child safety seat and the method of quick disassembly through the connecting component 3 and the unlocking component can also be applied between the child safety seat and the ordinary seat, or a part of the connecting component 3 is aligned with the vehicle. The other part of the connecting component 3 is connected to the ordinary seat, as long as it can be quickly disassembled and assembled through the above-mentioned connecting component 3 and the unlocking component. In addition, in other embodiments, two engaging pieces 32 that are rotatably connected to each other can also be provided, and a connection bayonet is formed through the space between the two engaging pieces 32 .

The unlocking assembly includes an unlocking drive part and a transmission assembly. The unlocking drive part is rotationally connected to the mounting base 2 . One end of the transmission assembly is connected to the unlocking drive part, and the other end of the transmission assembly is connected to the first connecting member 31 . In this embodiment, the transmission assembly uses a connecting cable 61. Correspondingly, the unlocking driving part is rotationally connected to the bottom of the seat body 1. One end of the connecting cable 61 is connected to the unlocking driving part, and the other end of the connecting cable 61 is connected to the unlocking driving part. to the engaging piece 32.

When multiple connection components 3 are provided at the bottom of the installation base 2, by providing the connection cable 61, it is convenient to operate the engaging parts 32 on all the connection components 3 through an unlocking drive part to realize all connection locks. The ports can be unlocked or locked at the same time. In addition, the rotational connection between the unlocking driving part and the installation base 2, that is, with the seat body 1, not only facilitates the installation of the unlocking component, but also allows the seat body 1, which is relatively stable relative to the vehicle state, to be used as the connection base point to achieve a more stable operation. for stable operation.

During the rotation of the unlocking driving part relative to the seat body 1 , since the connecting cable 61 is connected to the unlocking driving part, during the rotation, the unlocking driving part will exert a pulling force on the connecting cable 61 , and the pulling force acts on the locking cable 61 . The connecting piece 32 can then be driven to rotate relative to the connecting piece 31 to adjust the size of the bayonet opening. This operation method is simpler and more convenient, and has a simple structure and is convenient to set up.

Among them, the connecting cable 61 can be a flexible guide tube, and the connecting cable 61 can be directly fixed to the engaging piece 32, so that the engaging piece 32 can be directly operated and the force transmission effect is better. Alternatively, a crank connecting rod can be provided on the connecting piece 31 that can be movably connected to the engaging piece 32 , and the connecting cable 61 is connected to the crank connecting rod, and then the engaging piece 32 is operated through the crank connecting rod to perform relative motion. The rotational movement of the connecting member 31 allows for greater flexibility in setting the extension direction and movement direction of the connecting cable 61 while not affecting the driving operation of the engaging member 32 .

In some other embodiments, the unlocking component can also drive the engaging member 32 in other ways. For example, the unlocking assembly includes a number of driving components that are the same as the number of the engaging parts 32, and the driving components are arranged between the engaging parts 32 and the connecting parts. Between the connectors 31, they are used to provide rotational force for the engaging member 32. A control button is provided on the seat body 1 and is connected to all driving components for controlling all driving components. On this basis, it is connected to the vehicle's power system or a battery is provided inside the child safety seat to provide power support for the driving components.

In some specific embodiments, the unlocking driving part includes a driving rod 62. The driving rod 62 is rotationally connected to the mounting base 2, that is, the bottom of the seat body 1, and the rotation axis of the driving rod 62 relative to the seat body 1 is the driving direction. In the axial direction of the rod 62, one end of the connecting cable 61 is connected to the driving rod 62. The rotation axis direction of the driving rod 62 relative to the seat body 1 is the axis direction of the driving rod 62, that is, the driving rod 62 can rotate around its own axis relative to the seat body 1, and during its rotation, the connecting cable 61 is pulled. The driving rod 62 is caused to move as it rotates, thereby pulling the engaging member 32 . Setting the unlocking driving part as the driving rod 62 makes the rotation process smoother and makes it more convenient to connect with the seat body 1 .

In this embodiment, the driving rod 62 is disposed at the bottom of the seat body 1 along a transverse direction, which can be the width direction of the seat or the length direction of the seat. Preferably, it can be disposed at a position convenient for the user. The operating position, such as the bottom of the seat facing the door.

In other embodiments, in order to achieve the same effect on the unlocking drive part and enable the opening of the connection bayonet to be adjusted more quickly, a second engaging member 32 may be rotatably connected to the connecting member 31 so that the engaging member 32 and the second engaging member 32 to form a connection bayonet. On this basis, the other end of the connecting cable 61 has a first connecting end and a second connecting end. The first connecting end is connected to the engaging member 32 , the second connecting end is connected to the second engaging member 32 , and the first connecting end is connected to the engaging member 32 . The connecting end can move in a direction away from the second engaging member 32 , and the second connecting end can move in a direction away from the engaging member 32 . That is to say, by operating the two latching members 32 simultaneously through the connecting cable 61, the opening of the connecting bayonet can be adjusted to a larger extent. On the basis of further improving the disassembly and assembly speed, it is also more convenient to connect to the vehicle floor. corresponding buckles to connect.

In order to make the operation more convenient for the user, an unlocking handle 64 is also provided on the driving rod 62. One end of the unlocking handle 64 is fixedly connected to the driving rod 62, and the other end of the unlocking handle 64 extends away from the driving rod 62. That is to say, by extending the unlocking handle 64 to the outside of the bottom of the seat body 1, it is convenient for the user to rotate the driving rod 62, and the operation is more convenient.

In addition, the unlocking assembly may further include support rods 63 , which are provided at both ends of the driving rod 62 , and the ends of the two support rods 63 that are away from each other are connected to the bottom of the seat body 1 .
