Detailed Description

In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.

The invention provides a technical scheme for automatically starting a seat side protection system when or before a safety seat rotates to a standard use position, wherein the standard use position refers to an angle position where the safety seat is supposed to be located in the running process of a vehicle, and the standard use position can be divided into a forward mounting type only, a backward mounting type only and a forward and backward optional type according to the type of the specific safety seat. Typical canonical use locations include installation locations that are toward the front of the vehicle, or toward the rear of the vehicle.

In the prior art, in order to put a child into the safety seat conveniently, the seat body of the safety seat is arranged to be rotatable relative to the base, the child is put into the safety seat when the seat body of the safety seat faces a vehicle door, and then the seat body is rotated to the standard use position, the seat body is locked at the position by the locking mechanism, and the seat body cannot rotate unless unlocked, so that the seat body of the safety seat cannot be separated from the standard use position in driving.

Example one

The present embodiment provides a child car safety seat with a side protection function, and referring to fig. 1 to 12, the child car safety seat includes a base 2, a seat body 1 disposed on the base 2, and a side protection body 5 at a seat body backrest, and the seat body 1 can rotate on the base 2. During the process of rotating to the working state, the side protection body 5 is triggered to pop up and is converted to the protection state.

When the safety seat is used, the safety seat is placed on a rear seat of an automobile, the base 2 is fixed with the rear seat of the automobile, and the front and back directions of the base 2 are consistent with those of the rear seat of the automobile; it is not assumed that the safety seat is close to the left door; the orientation of the child sitting in the child car safety seat is the orientation of the seat body 1, the seat body 1 faces the left car door at the moment, and therefore an adult can conveniently place the child in the safety seat from the outside of the car. Then, the adult rotates the seat body 1 counterclockwise to the working state, that is, the seat body 1 faces the rear of the automobile seat, and the side protection block 5 on the right side of the seat body 1 automatically pops out and protrudes out of the side of the seat body 1 in the process. It should be noted that, in the present embodiment, since the seat body 1 is directed rearward in operation, opposite to the front-rear direction of the automobile, the right side of the seat body 1 approaches the left door at this time.

The safety seat can also be placed close to the right car door, and the seat body 1 can be rotated clockwise after children are put in the safety seat; the seat body 1 may be set to an operating state when it faces the front of the vehicle seat. For convenience of explanation, the present embodiment is taken as an example in which the vehicle is placed at a left door and faces rearward during operation (the right side protector 5 is ejected); the clockwise direction, the counterclockwise direction and the like are based on the visual angle of the safety seat viewed from the top.

In this embodiment, the mechanism by which the side protective body 5 can be automatically ejected as the seat body 1 rotates is implemented by the following structure:

the seat body 1 is provided with a slide 51 on the backrest for accommodating the side protective bodies 5 and restricting the moving direction and path of the side protective bodies 5, and two side protective blocks 5 in the slide 51 are arranged in bilateral symmetry. The lock block 33 passes through the first lock hole 54 on the side protection body 5 and the second lock hole 55 on the slideway wall, and because the third spring 34 is arranged between the lock block 33 and the seat body 1, the elastic force of the third spring 34 and the limiting action of the second lock hole 55 enable the lock block 33 to lock the side protection body 5 in the slideway 51; as can be seen from fig. 9, the side protective body 5 is connected to the inside of the slide 51 by the first spring 53, and when the side protective body 5 is locked, the first spring 53 is compressed by the side protective body 5; when the locking piece 33 moves out of the first locking hole 54, the side protective body 5 is outwardly ejected along the slide 51 by the restoring force of the first spring 53.

The lock piece 33 is connected to the coupling member 32 at the bottom of the seat body 1 through the traction cable 31. One end of the connecting piece 32 is connected with the seat body 1 through the rotating shaft 321, the other end is connected with the traction cable 31, and the section connected with the traction cable 31 can rotate relative to the seat body 1 under the action of external force; also, the link 32 is also connected to the seat body 1 by a second spring 322, and the second spring 322 is used to urge the link to be held at a specific position.

The base 2 is provided with a stopper 4, and the stopper 4 is located on a moving path of the connecting member 32. When the seat body 1 is rotated counterclockwise, the link 32 rotates with the seat body 1, and is stopped by the stopper 4 when contacting the stopper, and rotates about the rotation shaft 321 as the axis line with respect to the seat body 1, and the end of the link 32 connected to the pull cable 31 is largely displaced by being far from the rotation shaft 321, thereby pulling the pull cable 31, so that the lock piece 33 is pulled out of the first lock hole 54, and the side protector 5 pops up, and is converted from the unprotected state to the protected state.

Referring to fig. 3, the seat body 1 is oriented toward the door, and the state of the side protective body 5 corresponds to fig. 9; referring to fig. 4 and 7, the connecting member 32 hits the stopper 4 and starts to rotate; referring to fig. 5 and 8, the coupling member 32 is rotated to the maximum angle, the traction cable 31 is maximally stressed, the state of the side protective body 5 corresponds to fig. 12, and it will be ejected immediately (corresponding to fig. 10); referring to fig. 6, the link 32 is restored by the second spring 322 after passing the stopper 4, and the side protective body 5 has been ejected in the protective state, corresponding to fig. 11.

If the seat body 1 rotates by half, the connecting piece 32 touches the stop 4 and rotates, so that the side protective body 5 can be popped out before the seat body 1 rotates in place; if the seat body 1 is rotated to be in place, the link 32 hits the stopper 4 and rotates, the ejection of the side protective body 5 can be made almost synchronous with the rotation of the seat body 1 in place. The setting position of the stopper 4 affects the specific timing of the ejection of the side protective body 5.

The position of the seat body 1 when it faces the door is referred to as an initial position, the position of the seat body when it is in an operating state (i.e., toward the front or rear) is referred to as an end position, and the difference in the rotational angle between the initial position and the end position is greater than 0 °, preferably greater than or equal to 0 ° and equal to 180 °, and more preferably greater than or equal to 30 ° and equal to 150 °. Generally, the angle required to rotate from the initial position to the final position is 45 ° to 135 °, preferably 60 ° to 120 °, more preferably 75 ° to 105 °, for the convenience of placing a child, and this angle can be referred to the angle between the seat vertical surface 101 and the base vertical surface 201 in fig. 3 to 6.

For convenience, the seat body 1 can be further rotated through the end position at different sides of the rear seat of the vehicle. The safety seat can lock the seat body 1 at the end position, and after the seat body rotates to the end position, if the seat body needs to continue to rotate, the seat body needs to be rotated by an extra force by an adult to leave the end position, or unlocked in other ways.

The user can manually push the side guards 5 back into the slide. In this embodiment, in the process that the seat body 1 rotates to the end position, the connecting member 32 returns under the action of the second spring 322 after passing through the stopper 4, the lock block 33 moves into the slide rail 51 to return under the action of the third spring 34 and is located on the slide path of the side protective body 5, the lock block 33 is provided with a guide inclined surface 331, and the side protective body 5 presses the guide inclined surface 331 when being pushed back, so that the lock block 33 is pushed out of the movement path of the side protective body 5, see fig. 12; when the side protective body 5 is pushed back completely, the first lock hole 54 is opposed to the lock piece 33, and the lock piece 33 is inserted into the first lock hole 54 by the restoring force of the third spring 34 to lock the side protective body 5 in the non-protective state, see fig. 9.

Specifically, the traction cable 31 passes through an elongated sleeve body 311, and the sleeve body 311 is at least partially fixed relative to the seat body 1, so as to define the position of the traction cable 31. The lower end of the third spring 34 is fixed to the upper end portion of the sheath body 311, and the upper end of the third spring 34 is connected to or abutted against the third spring 34, so that the third spring 34 tends to be located on the sliding path of the side protective body 5.

The traction cable 31 is preferably made of a non-elastic or stiff material, the less the connector 32 is stretched when it is blocked by the stop 4, so that the lock 33 can exert sufficient pressure on the third spring 34; the covering 311 may be a leather cover or a metal tube, or a hole may be formed in the seat body 1 for the traction cable 31 to pass through without providing the covering 311.

Referring to fig. 3 to 6 and 9 to 12, two traction cables 31 are arranged in a crossing manner; the following effect can be reached in cooperation with the rotation direction of the seat body 1 and the setting position of the stopper 4: when the seat body 1 rotates clockwise to a working state, the side protection body 5 on the left side pops up; when the seat body 1 is rotated counterclockwise to the operating state, the right side protective body 5 is ejected. Here, "left" and "right" refer to the orientation of the seat body 1 itself. Therefore, regardless of which door the safety seat is close to, regardless of whether the operating state of the seat body 1 is forward or backward, the side protective body 5 closest to the door can be surely ejected, providing lateral protection for the child.

Example two

The present embodiment differs from the first embodiment mainly in the blocking mechanism.

Referring to fig. 13 to 16, the two traction cables 31 in this embodiment are not crossed. Each of the two traction cables 31 is connected to a connector 32, and the two connectors 32 share a rotating shaft 321. The base 41 is arranged on the base 2, is generally fixed relative to the base 2 and cannot move relative to the base; the base 41 is provided with a stopper 4, and a space for the rotation of the connector 32 is left in a portion other than the stopper 4.

Referring to the process of the first embodiment in which the seat body 1 is rotated counterclockwise to eject the right protector 5, the process can also occur in this embodiment, and specifically, the lubrication of the rotating shaft 32 is better, the friction between the base 41 and the link 32 is small, when the seat body 1 rotates, the side protection device follows the seat body 1, pulls the traction cable 31, the traction cable 31 pulls the link 32, and the base 41 and the stopper 4 are stationary with respect to the base 2, i.e., the link 32 rotates about the rotating shaft 321 with respect to the base 2. Referring to fig. 14 and 16, it can be seen that the link 32 corresponding to the left-hand protective body 5 has rotated about the rotation axis 321, while the link 32 corresponding to the right-hand protective body 5 has not rotated relative to the base 41, because this link 32 is blocked by the stopper 4 (or has rotated for a while and then is prevented from continuing to rotate by encountering the stopper 4 again). Therefore, when the upper end of the traction cable 31 has been displaced, the lower end of the traction cable 31 cannot be displaced accordingly, and therefore the right traction cable is pulled, which triggers the lock mechanism at the upper end of the traction cable 31 to unlock, and the right protector 5 to pop out.

The rotating shaft 321 is positioned close to or coincident with the rotating shaft of the seat body 1, and the slide track 51 is positioned at the backrest of the seat body 1,

It should be noted that the "space for allowing the connecting member 32 to rotate" in this space, the size of the angle at which the connecting member 32 can rotate affects the specific ejection timing of the protective body 5, the larger the angle is, the later the ejection timing of the protective body is, the too small angle may cause too large tension in the traction cable to accelerate aging, and the too large angle may cause the ejection mechanism to be insensitive, so the angle is preferably about 10 ° to 60 ° smaller than the rotation angle of the seat body 1, and more preferably 30 ° to 45 ° smaller.

In this embodiment, the connector 32 cannot pass over the stopper 4. In order to use the safety seat at the rear seat position of the vehicle when the safety seat is shifted from the left door to the right door, referring to fig. 17, not only the seat body 1 needs to be adjusted to be rotated past the end position, but also the base 41 needs to be rotated so that the space in which the link 32 is rotated can be matched with the position of the seat body 1.

One end of the third spring 34 is connected or abutted with the locking block 33, and the other end can be connected with the upper end of the sleeve body 311 as in the first embodiment; but alternatively a point of force may be provided for the third spring 34. In this embodiment, the slide 51 is provided with a receiving cavity 52 for receiving the lock 33 and the third spring 34, and a bottom wall of the receiving cavity 52 provides a force application point for the third spring 34.

EXAMPLE III

As shown in fig. 18 to 27, the present embodiment is different from the above embodiments in that: in this embodiment, the number of the protective members 5 is not two, but one. Therefore, in the first and second embodiments, the protector 5 on both sides may be ejected without continuously rotating the seat body 1 and retracting the ejected protector 5, but when the protector 5 is in the protection state in the present embodiment, the protector is located on either the left side or the right side of the seat body 1, and the side protectors 5 may protrude on both sides of the seat body 1.

In this embodiment, the seat body 1 has a backrest 11, a slide rail 51 and a protection body 5 sliding in the slide rail 51 are disposed on the rear side of the backrest 11, a first slide groove 57 is disposed on the backrest 11 and the slide rail 51, the protection body 5 and a linkage piece 56 disposed on the front side of the backrest 11 are connected by a first pin 58 passing through the first slide groove 57, and the linkage piece 56 can drive the protection body 5 to slide in the slide rail 51 along the direction of the first slide groove 57 by the first pin 58; the lower end of the linkage 56 is connected to a second chute 562 on the backrest 11 through a second pin 561; one end of the first spring 53 is also connected to the second pin 561, and the other end is rotatably connected to the backrest 11 through the first rotating shaft 531.

The safety seat further includes two locking members 61 disposed approximately bilaterally symmetrically, the locking members 61 are rotatably disposed on the seat body 1 through a second rotating shaft 613, first ends 611 of the locking members 61 extend downward, the first ends 611 of the two locking members 61 are disposed to intersect, and the upper end portions of the interlocking members 56 can be restricted to a balanced position corresponding to an unprotected state in which the protection body 5 is stored in the slide 51; the second end 612 of the locking member 61 is connected to the traction cable 31, and the traction cable 31 first extends obliquely upward, turns around the turning point 62, extends downward, and is finally connected to the connecting mechanism at the bottom of the seat body 1.

Taking the example in which the safety seat is close to the right door and the seat body 1 is oriented rearward in the operating state, the protective body 5 is ejected from the left end of the slide rail 51 in accordance with the rotation of the seat body 1, see fig. 20, 25, and 26 (these three figures are viewed when the observer faces the backrest 11, but the definition of the left and right is based on the orientation of the seat body 1 itself).

Referring to fig. 20, at this time, the first spring 53 is in an extended state, the upper end of the linkage 56 contacts with the two locking members 61, the first pin 58 is located at a balanced position in the first sliding slot 57, the second pin 561 is located at a lower position in the second sliding slot 562, and the locking members 61 and the limiting effects of the first and second sliding slots 57, 562 on the linkage 56 also keep the first spring 53 in a long state; when the seat body 1 rotates clockwise, the left traction cable 31 is pulled downward by the action between the connecting mechanism and the blocking mechanism, and the rotation point 62 is used for rotating the traction cable 31, so that the second end 612 of the locking member 61 is correspondingly lifted and rotates counterclockwise, the first end 611 of the locking member also rotates counterclockwise, the upper part of the linkage member 56 is pushed to move left, the linkage member 56 rotates clockwise, the balance is lost, accordingly, the second pin 561 slides up the second sliding groove 562 under the action of the restoring force of the first spring 53, the clockwise rotation of the linkage member 56 is further promoted, and the first pin 58 drives the protective body 5 to extend from the left side. In this paragraph, in addition to describing the rotation of the seat body 1, other references to clockwise and counterclockwise should be made with reference to the case when the observer faces the backrest 11.

The specific arrangement of the connecting mechanism and the blocking mechanism in the embodiment can refer to other embodiments; when the protector 5 needs to be stored, it needs to be manually pushed back into the slide 51.

Obviously, instead of using an elongated spring, a shortened spring may be used to "further facilitate the rotation of the linkage 56", in which case the first rotation axis 531 should be lower than the second pin 561; both schemes utilize the restoring force of the spring without substantial difference, so the scheme of utilizing the elastic restoring force to drive the protective body 5 to pop up falls into the protection scope of the invention.

Example four

Referring to fig. 28 to 34, in the present embodiment, the number of the protective bodies 5 is also one. The safety seat comprises a slide way 51 on the seat body 1 and a protective body 5 in the slide way 51, wherein a first sliding groove 57 is formed in one side, close to the seat, of the slide way 51, a second sliding groove 562 is formed in the upper part of a linkage piece 56, and a first pin shaft 58 penetrates through the first sliding groove 57 and the second sliding groove 58, so that the linkage piece 56 is rotatably connected with the protective body 5 in the slide way 51; the linkage 56 is rotatably connected to the seat body 1 via a first rotating shaft 563, and a bump 564 is formed at a lower portion of the linkage 56. The upper end of the first spring 53 is connected to a spring connecting portion 59 fixed to the interlocking member 56, and the lower end of the first spring 53 is connected to the seat body 1. The safety seat further includes a locking member 61 capable of maintaining the interlocking member 56 at a balanced position, the locking member 61 is disposed on the seat body 1, and both end portions of the locking member 61 are connected to the traction cable 31, respectively, and the locking member 61 is capable of sliding horizontally with respect to the seat body 1 under the traction of the traction cable. The two ends of the locking member 61 are respectively provided with a second spring 63 which can make the locking member 61 tend to keep at the middle position, one end of the second spring 63 is fixedly or detachably connected with the seat body 1, and the other end is connected with or abutted against the locking member 61. The other end of the traction cable 31 is connected with the base 2, and the base 2 is also provided with a blocking mechanism comprising a stop block 4.

Referring to fig. 32, the two dotted lines are horizontal and vertical, and the mechanism connected to the upper end of the traction cable 31 rotates with the seat body 1 relative to the base 2 and the stopper 4 on the base 2.

When the protection body 5 is in the non-protection state, the bump 564 is caught by the locking member 61, and the linkage member 56 is in the equilibrium position, see fig. 29 and 30; since the position of the linkage 56 is temporarily fixed, the first spring 53 is in and kept in an extended state at this time.

In the process of counterclockwise rotating the seat body 1 (from the top view) to the end position, referring to fig. 31, the pulling cable 31 on the right side (referring to the orientation of fig. 31 itself) is blocked by the stopper 4 when the seat body 1 moves to pull the locking member 61, so that the locking member 61 moves to the right against the elastic force of the second spring 63 and pushes the bump 564, so that the linkage member 56 shifts to the equilibrium position, the first spring 53 contracts due to the restoring force to further drive the linkage member 56 to rotate counterclockwise, and the protection member 5 is driven to protrude from the right side of the seat body 1.

In some embodiments, the stop 4 can be shaped as in the second embodiment so that the traction cable 31 cannot pass through, and accordingly the position of the stop 4 should also be adjusted in the replacement position of the safety seat.

In some embodiments, the upper portion of the block 4 is provided with a guide portion, and the traction cable 31 blocked by the block 4 slides over the block 4 after being tightened to a certain extent, in which case the position of the block 4 may not be changed.

EXAMPLE five
