Description

Technical Field

[0001] The present invention relates to the technical field of child carriers, and particularly to a child carrier. Background Art

[0002] For child carriers, such as child safety seats, five-direction buckles or body protectors are generally provided to fix children. When fixing a child with a body protector, the contact area between the body protector and the child is relatively large. When an accident such as a collision occurs, while the body protector protects the child, the pressure exerted by the body protector itself on the child is also relatively small. Therefore, it is widely used. To adapt to children of different body types, the body protector is generally an adjustable structure. However, the operating parts of the adjustment structure of the body protector are usually arranged on both sides of the body protector and require both hands to operate, which is inconvenient to use.

[0055] Such as Figure 1 And Figure 2As shown in the figure, an embodiment of the present invention provides a child carrier, specifically a child safety seat, which includes a seat 100, a body protector 200, an adjustment mechanism 300, an operating member 400, and a locking mechanism 500. The body protector 200 is detachably fixed to the seat 100, and a seating space 600 for accommodating a child is formed between the body protector 200 and the seat 100. The adjustment mechanism 300 is disposed between the body protector 200 and the seat 100 and is used to adjust the distance between the body protector 200 and the seat 100, that is, to adjust the size of the seating space 600. The adjustment mechanisms 300 are provided on both sides of the body protector 200, and the operating member 400 is respectively connected to the adjustment mechanisms 300 located on both sides of the body protector 200. Alternatively, an adjustment mechanism 300 may be provided on one side of the body protector 200, and a linkage mechanism (not shown in the figure) may be provided on the other side of the body protector 200, and the operating member 400 is respectively connected to the adjustment mechanism 300 and the linkage mechanism. The locking mechanism 500 is used to achieve the detachable connection between the body protector 200 and the seat 100. This child carrier can achieve one-handed adjustment of the distance between the body protector 200 and the seat 100, which is convenient to use.

[0056] Specifically, as Figure 1 and Figure 5 shown in the figure, the seat 100 includes a backrest 110 and a seat cushion 120 that are connected to each other. The body protector 200 may be a lightweight solid block structure or a shell structure made of foam materials such as expanded polystyrene (EPS), expanded polypropylene (EPP), or expanded polyethylene-polystyrene (EPO). In this embodiment, the body protector 200 has a first surface 210 facing the seat 100, and the first surface 210 is a concave surface to enclose a seating space 600 for accommodating a child with the seat 100. The body protector 200 also has a second surface 220 facing away from the seat 100, and the second surface 220 is a convex surface, generally in the shape of a partial spherical surface.

[0057] As Figures 5 to 10 shown in the figure, the adjustment mechanism 300 is used to adjust the distance between the body protector 200 and the seat 100, that is, to adjust the size of the seating space 600. Specifically, the adjustment mechanism 300 includes an adjustment component 310, a sliding component 320, a release locking component 330, and a connecting component 340. The adjustment component 310 is fixed to any side 230 of the body protector 200, the sliding component 320 is used to be connected to the seat 100, and the adjustment component 310 is slidably connected to the sliding component 320. The release locking component 330 is used to release the locking between the adjustment component 310 and the sliding component 320. The connecting component 340 is fixed to the sliding component 320 and is used to be detachably connected to the seat 100.

[0058] Specifically, as Figure 5 and Figure 6As shown, the adjustment component 310 includes an adjustment body 311 and a second reset member 312. The adjustment body 311 is generally in a long tubular structure. One side of the adjustment body 311 is fixed to any side 230 of the protective body 200, and a plurality of engaging holes 311a are provided on the side of the adjustment body 311 facing away from the protective body 200 along its length direction.

[0059] Furthermore, as Figures 5 to 7 shown, the sliding component 320 is located on the side 230 of the adjustment component 310 facing away from the protective body 200 and is slidably connected to the adjustment component 310. Specifically, the sliding component 320 includes a sliding body 321, an engaging member 322, and a first reset member 323. The sliding body 321 is generally in a shell-like structure. The engaging member 322 is movably disposed within the sliding body 321. The engaging member 322 includes an engaging body 322a and engaging teeth 322b fixed to the engaging body 322a. The side of the sliding body 321 facing the adjustment body 311 has a through hole (not shown in the drawings). The engaging member 322 can move to make the engaging teeth 322b protrude from the outer surface 314 of the sliding body 321 facing the adjustment body 311 through the through hole, and the engaging teeth 322b are in snap-fit with the engaging holes 311a.

[0060] In this way, relative locking between the sliding component 320 and the adjustment component 310 can be achieved, so that the protective body 200 is fixed relative to the seat 100 at a certain distance to form a seating space 600 of a certain size. When the sliding component 320 slides relative to the adjustment component 310 such that the engaging teeth 322b are engaged in different engaging holes 311a, the size of the seating space 600 can be adjusted.

[0061] In this embodiment, as Figure 7 shown, there are two engaging teeth 322b to improve the engagement stability between the engaging teeth 322b and the engaging holes 311a. Of course, in other embodiments, the number of the engaging teeth 322b can also be adjusted according to actual needs.

[0062] Furthermore, as Figure 6 and Figure 7 shown, the two ends of the first reset member 323 are respectively abutted against the engaging member 322 and the sliding body 321. The first reset member 323 always makes the engaging member 322 move in the direction close to the protective body 200 so that the engaging teeth 322b can automatically re-engage with the engaging holes 311a.

[0063] Of course, the cooperation mode between the adjustment component 310 and the sliding component 320 is not limited to this. The engaging hole 311a can be replaced with other engaging parts such as a groove or a ring according to actual needs, and the engaging tooth 322b can also be replaced with other engaging parts such as a protrusion or a hook according to actual needs. In this embodiment, a plurality of first engaging parts (such as the engaging hole 311a) are provided on the adjustment component 310, and a second engaging part (such as the engaging tooth 322b) for cooperating with the first engaging part is provided on the sliding component 320. Of course, in other embodiments, the arrangement positions of the first engaging part and the second engaging part can also be interchanged, as long as the adjustment component 310 and the sliding component 320 can be relatively fixed at different positions, and the specific form is not limited.

[0064] Further, as Figure 7 and Figure 10 shown, one side of the engaging tooth 322b also has a sliding inclined surface 322c, and the sliding inclined surface 322c is used to abut against the hole wall 311b of the engaging hole 311a. Thus, assuming that the sliding inclined surface 332c gradually moves away from the protective body 200 along the first direction F1, when it is necessary to move the protective body 200 in the opposite direction of the first direction F1, only need to push the protective body 200 in the opposite direction of the first direction F1. The hole wall 311b of the engaging hole 311a on the adjustment body 311 will push against the sliding inclined surface 322c, so that the engaging part 322 as a whole moves upward until the engaging tooth 322b disengages from the engaging hole 311a, and the adjustment component 310 and the sliding component 320 are unlocked, and at the same time the protective body 200 moves in the opposite direction of the first direction F1.

[0065] In this embodiment, the sliding inclined surface 322c is located on the side of the engaging tooth 322b facing the first direction F1 and gradually moves away from the protective body 200 along the first direction F1. When it is necessary to move the protective body 200 in the direction close to the seat 100, that is, to reduce the seating space 600, only need to push the protective body 200 in the direction close to the seat 100. As Figure 6 、 Figure 7 、 Figure 9 and Figure 10As shown, the unlocking component 330 is used to push the engaging component 322, so that the engaging component 322 is disengaged from the engaging hole 311a. The unlocking component 330 includes an interlocking member 331 and a driving member 332 that are connected to each other. The interlocking member 331 is generally in a rod-like structure. One end of the interlocking member 331 is fixedly connected to the operating member 400 and moves by driving the operating member 400. The part of the interlocking member 331 away from the operating member 400 extends into the adjustment body 311 and is located on one side 230 of the adjustment body 311 close to the protective body 200. A first driving inclined surface 331a is provided on the side 230 of the interlocking member 331 away from the protective body 200. The two ends of the second reset member 312 are respectively abutted against the interlocking member 331 and the adjustment body 311, and the second reset member 312 always moves the interlocking member 331 in the opposite direction to the direction of pushing the driving member 332 to unlock, such as moving in the opposite direction to the first direction F1. Specifically, a rivet 313 is fixed on the adjustment body 311, and the two ends of the second reset member 312 are respectively abutted against the interlocking member 331 and the rivet 313.

[0066] As Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the driving member 332 is arranged in the adjustment body 311. The driving member 332 can push the engaging component 322, so that the engaging component 322 is disengaged from the engaging hole 311a. The driving member 332 is generally in a rod-like structure and is placed on one side 230 of the adjustment body 311 away from the protective body 200. The side 230 of the driving member 332 away from the protective body 200 has a plurality of pushing protrusions 332a that abut against the engaging component 322. The plurality of pushing protrusions 332a are arranged corresponding to the plurality of engaging holes 311a. The pushing protrusions 332a can protrude through the engaging holes 311a to protrude from the outer surface 314 of the adjustment assembly 310 to push the engaging teeth 322b, so that the engaging teeth 322b are disengaged from the engaging holes 311a. In this way, the locking between the adjustment assembly 310 and the sliding assembly 320 can be released, so that the adjustment assembly 310 and the sliding assembly 320 can slide relative to each other to adjust the size of the riding space 600 between the protective body 200 and the seat 100.

[0067] As Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, on the side 230 of the driving member 332 close to the protective body 200, there is a second driving inclined surface 332b that cooperates with the first driving inclined surface 331a. In this embodiment, the second driving inclined surface 332b gradually moves away from the engaging hole 311a along the first direction F1. Thus, when it is necessary to move the protective body 200 along the first direction F1, the linkage member 331 can be pulled to move in the first direction F1. In this way, under the pushing action of the first driving inclined surface 331a, the second driving inclined surface 332b of the driving member 332 will move in the direction away from the protective body 200, so that the whole driving member 332 moves in the direction away from the protective body 200, that is, close to the engaging hole 311a. Then, the pushing convex 332a on the driving member 332 can pass through the engaging hole 311a and protrude from the outer surface 314 of the adjusting assembly 310 to push the engaging tooth 322b, so that the engaging tooth 322b disengages from the engaging hole 311a.

[0068] Further, as Figures 1 to 4 shown, the operating member 400 is generally in a rod-like structure. In this embodiment, both ends of the operating member 400 are fixedly connected to the connecting members 340 of the adjusting mechanisms 300 located on both sides of the protective body 200. Of course, in other embodiments, it can also be that the middle part or other positions of the operating member 400 are fixedly connected to the connecting members 340 of the adjusting mechanisms 300 located on both sides of the protective body 200. Thus, by pulling the operating member 400, the two adjusting mechanisms 300 can be simultaneously acted on to adjust the distance between the protective body 200 and the seat 100, which can be operated with one hand without the need to stretch both hands to both sides of the protective body 200 to adjust the adjusting mechanisms 300, and the operation is convenient. In this embodiment, the operating member 400 is located on the side of the protective body 200 facing away from the seating space 600, that is, the second surface 220, so it is more convenient for the user to operate. Of course, in other embodiments, the operating member 400 can also be located on the top or other positions of the protective body 200 as long as it is convenient for operation.

[0069] As Figure 1 、 Figure 2 and Figures 5 to 10 shown, the adjustment process of the protective body 200 relative to the seat 100 is as follows:

[0070] When it is necessary to move the protective body 200 in the direction away from the seat 100, that is, to increase the seating space 600, the operating member 400 is pulled in the direction away from the seat 100. The operating member 400 drives the linkage member 331 to move in the first direction F1. The driving member 332, which originally cooperates with the first driving inclined surface 331a of the linkage member 331 with the second driving inclined surface 332b, moves in the direction away from the protective body 200 under the pushing action of the first driving inclined surface 331a, so that the pushing convex 332a on the driving member 332 pushes the engaging tooth 322b, and finally the engaging tooth 322b disengages from the engaging hole 311a, as Figure 10As shown. Then, the adjustment component 310 and the sliding component 320 are unlocked and can slide relative to each other. Since the adjustment component 310 is fixed to the body protector 200 and the sliding component 320 is used to connect to the seat 100, when the adjustment component 310 slides relative to the sliding component 320, it is equivalent to the body protector 200 sliding relative to the seat 100. Thus, when the adjustment component 310 moves relative to the sliding component 320 in the first direction F1, the distance between the body protector 200 and the seat 100 increases, that is, the riding space 600 increases. After the adjustment component 310 moves relative to the sliding component 320 to the required position, the operating member 400 is released. The linkage member 331 moves in the direction opposite to the first direction F1 under the action of the second reset member 312, and at the same time drives the driving member 332 to move towards the body protector 200. At the same time, the engaging member 322 also moves towards the body protector 200 under the action of the first reset member 323, and finally the engaging teeth 322b are engaged with other engaging teeth 322b, as shown in the figure, so as to realize the relative fixation of the adjustment component 310 and the sliding component 320, that is, to realize the relocking of the body protector 200 and the seat 100.

[0071] When it is necessary to move the body protector 200 towards the seat 100, that is, to reduce the riding space 600, only the body protector 200 needs to be moved in the direction opposite to the first direction F1. At this time, the sliding inclined surface 322c on the engaging member 322 moves upward under the pushing action of the hole wall 311b of the engaging hole 311a, driving the engaging teeth 322b to disengage from the engaging hole 311a. The adjustment component 310 and the sliding component 320 are unlocked, that is, the body protector 200 and the seat 100 are unlocked. The body protector 200 moves towards the seat 100, and the riding space 600 is reduced. When the body protector 200 moves relative to the seat 100 to the required position, the pushing of the body protector 200 is stopped. The engaging member 322 moves towards the body protector 200 under the action of the first reset member 323 until the engaging teeth 322b are engaged with other engaging holes 311a, so as to realize the relative fixation of the adjustment component 310 and the sliding component 320, that is, to realize the relocking of the body protector 200 and the seat 100.

[0072] As Figures 11 to 14 shown, the locking mechanism 500 has a locked state and an unlocked state. When the locking mechanism 500 is in the locked state, the body protector 200 is locked and fixed to the seat 100. When the locking mechanism 500 is in the unlocked state, the body protector 200 can be detached from the seat 100. Specifically, the locking mechanism 500 includes a connecting portion 510 (such as Figure 3 and Figure 4As shown in the figure, a locking housing 520, a connecting pin 530, a release button 540, and a third reset member 550. The connecting portion 510 is provided on the connecting member 340, the locking housing 520 is fixed to the seat 100, the connecting pin 530 is movably disposed in the locking housing 520, one end of the release button 540 is connected to the connecting pin 530, and both ends of the third reset member 550 are respectively abutted against the release button 540 and the locking housing 520.

[0073] As Figure 3 and Figure 4 shown, the connecting portion 510 specifically includes a connecting hole 511 and a connecting port 512 provided on the connecting member 340 and communicating with each other. The aperture of the connecting hole 511 is larger than the diameter of the connecting port 512. In this embodiment, the connecting portion 510 is provided at one end of the connecting member 340 away from the sliding assembly 320, but is not limited thereto.

[0074] As Figure 12 and Figure 14 shown, the locking housing 520 is generally in the structure of a rectangular parallelepiped housing, and an accommodation cavity 521 for accommodating the connecting pin 530 is provided inside. The locking housing 520 is provided with an insertion interface (not shown in the drawings) communicating with the accommodation cavity 521, and the insertion interface can be inserted by the connecting member 340.

[0075] As Figure 12 , Figure 14 and Figure 15 shown, the connecting pin 530 is generally in a columnar structure and includes a fixing portion 531, a release portion 532, and a blocking portion 533 connected in sequence. The fixing portion 531 is used for connecting with the release button 540. The radial dimension R1 of the release portion 532 is smaller than the diameter of the connecting port 512. The radial dimension R2 of the blocking portion 533 is larger than the diameter of the connecting port 512 and smaller than the aperture of the connecting hole 511. The connecting pin 530 is inserted into the connecting hole 511 through the connecting port 512, and the connecting pin 530 can move so that the blocking portion 533 or the release portion 532 is located in the connecting hole 511.

[0076] As Figure 12 and Figure 14 shown, the release button 540 is fixed to the fixing portion 531 of the connecting pin 530. The release button 540 is partially placed in the accommodation cavity 521 and partially protrudes from the surface of the locking housing 520 for pressing operation.

[0077] Thus, when it is necessary to install and fix the protective body 200 on the seat 100, then as shown in Figure 12 and Figure 14Press the unlocking button 540 in the second direction F2, and at the same time insert one end of the connecting member 340 having the connecting portion 510 into the receiving cavity 521 through the insertion opening. The insertion direction of the connecting member 340 is perpendicular to the length direction of the connecting pin 530. At this time, the unlocking portion 532 of the connecting pin 530 is opposite to the connecting port 512. Since the radial dimension R1 of the unlocking portion 532 is smaller than the caliber of the connecting port 512, the connecting pin 530 is inserted into the connecting hole 511 through the connecting port 512, as shown in Figure 14 shown. Then release the unlocking button 540. The unlocking button 540 is reset in the opposite direction of the second direction F2 under the action of the third reset member 550, and at the same time drives the connecting pin 530 to move in the opposite direction of the second direction F2 until the blocking portion 533 of the connecting pin 530 is located in the connecting hole 511 and is opposite to the connecting port 512. Since the radial dimension R2 of the blocking portion 533 is larger than the caliber of the connecting port 512 and smaller than the aperture of the connecting hole 511, the blocking portion 533 forms a blocking effect on the connecting port 512, and the connecting member 340 cannot be pulled out of the receiving cavity 521, as shown in Figure 12 shown. In this way, the connection and fixation between the sliding assembly 320 and the seat 100 can be realized, that is, the installation and fixation of the protective body 200 on the seat 100.

[0078] When it is necessary to detach the protective body 200 from the seat 100, press the unlocking button 540 along the second direction F2, so that the connecting pin 530 moves along the second direction F2 until the unlocking portion 532 of the connecting pin 530 is located in the connecting hole 511 and is opposite to the connecting port 512, as shown in Figure 14 shown. Since the radial dimension R1 of the unlocking portion 532 is smaller than the caliber of the connecting port 512, the unlocking portion 532 can move out of the connecting hole 511 from the connecting port 512, that is, at this time, one end of the connecting member 340 having the connecting portion 510 can be pulled out of the receiving cavity 521, and the fixation between the sliding assembly 320 and the seat 100 is released, and the protective body 200 can be detached from the seat 100.

[0079] Of course, other methods can also be used to realize the detachable connection between the protective body 200 and the seat 100. For example, a rotatable connecting hook is provided on the sliding assembly 320, and a connecting hole 511 matching the connecting hook is provided on the seat 100, etc., and no limitation is made thereto.

[0080] The children's vehicle of the present invention has at least the following technical effects:

[0081] In this children's vehicle, an adjusting mechanism 300 for adjusting the size of the seating space 600 is provided on one side of the protective body 200, and is connected to the adjusting mechanism 300 on one side of the protective body 200 through an operating member 400. In this way, by operating the operating member 400, it can act on the adjusting mechanism 300 on one side of the protective body to adjust the distance between the protective body 200 and the seat 100, that is, to adjust the size of the seating space 600. It can be operated with one hand, without having to place both hands on both sides of the protective body 200 for adjustment, which is convenient to use.

[0082] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0083] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
