[0065] Figures 1 to 3 A three-dimensional diagram of a child carrier 100 provided according to some embodiments of the present invention is shown. The child carrier 100 is, for example, a child safety seat, a child stroller, etc. The child carrier 100 is described as a child safety seat. The child safety seat can be fixed to the car seat by, for example, its own ISOFIX connector, upper pull belt and other structures, or fixed to the car seat by the car seat belt configured by the car. The child safety seat can be installed on the car seat in the forward direction or in the rearward direction.

[0066] like Figures 1 to 3 As shown, in some embodiments, the child carrier 100 includes a base 9, a seat assembly 1 movably disposed on the base 9, and a seat position display device 3 provided according to some embodiments of the present invention. The seat assembly 1 is provided with a backrest 12, and the seat assembly 1 can be moved relative to the base 9 along the front-to-back direction D1 so that the backrest 12 can be adjusted in angle relative to the base 9. Specifically, the seat assembly 1 moves along an arc relative to the base 9, and the movement along the arc has a movement component in the front-to-back direction D1. In this way, when the seat assembly 1 moves relative to the base 9 in the front-to-back direction D1, the inclination angle θ of the seat assembly 1 relative to the base changes accordingly. The seat position display device 3 is used to indicate the inclination angle θ of the seat assembly 1 relative to the base 9. Specifically, as Fig.10 and Fig.11As shown, the tilt angle θ may be the angle between the plane where the backrest body 121 of the backrest 12 is located and the plane where the contact surface between the base 9 and the car seat is located. The seat position display device 3 will be described together with the child carrier 100 hereinafter.

[0067] Combined with reference Fig.10 and Fig.11 In some embodiments, the base 9 includes an upper shell 9a and a lower shell 9b connected to the upper shell 9a, and the upper shell 9a and the lower shell 9b are enclosed to form a receiving chamber 9c. The seat assembly 1 is disposed on the upper shell 9a and can move relative to the upper shell 9a along the front-rear direction D1. The surface of the upper shell 9a forms an upper surface 901 of the base 9. The upper surface 901 of the base 9 is an arc-shaped surface, specifically, the upper surface 901 is an arc-shaped convex surface with a high middle portion and low surrounding portions. The surface of the lower shell 9b forms a lower surface 902 of the base 9, and the lower surface 902 is a substantially flat surface or an arc-shaped concave surface with a middle portion recessed toward the receiving chamber 9c, so as to facilitate the child carrier 100 to be stably placed on the car seat.

[0068] Combined with reference Figure 6 to Figure 7 The seat assembly 1 includes a seat body 11 and a backrest 12. The backrest 12 has two matching ribs 13 extending substantially along the front-rear direction D1 and a crossbar 14 connected to the two matching ribs 13. The seat body 11 is used for children to sit on. In some embodiments, as Figure 6 As shown, the seat body 11 is a child booster cushion, and the seat body 11 is detachably connected to the backrest 12. Among them, the seat body 11 is clamped on two matching ribs 13 and is detachably connected to the cross bar 14. The seat body 11 can be assembled with the backrest 12 as a child safety seat, and can also be used alone as a child booster cushion. Among them, the backrest 12 also includes a backrest body 121, and each matching rib 13 is connected to the backrest body 121 and extends in the front-to-back direction D1 in a direction away from the backrest body 121. Each matching rib 13 can be slidably connected to the base 9 along the front-to-back direction D1 to drive the backrest 12 to move relative to the base 9, thereby changing the inclination angle θ between the backrest 12 and the base 9. The two matching ribs 13 can both slide relative to the base 9 and be stably supported on the base 9. In some other embodiments, the seat body 11 and the backrest 12 are an integral part. The exemplary seat assembly 1 is a baby carrier, wherein the seat body 11 and the backrest 12 are integrally formed of polyethylene material, and two connecting rods are provided at the lower part of the baby carrier, which are detachably connected to the base 9 through the connecting rods and can slide forward and backward relative to the base 9. In some other embodiments, the seat body 11 is slidably connected to the base 9, and when the seat body 11 slides relative to the base 9, the angle between the plane where the seat body 11 is located and the plane where the contact surface between the base 9 and the car seat is located changes with the position of the seat body 11.

[0069] For the convenience of description, the following description will take the matching rib 13 located on the left side as an example.

[0070] like Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, the matching rib 13 includes a rib body 132 and a rib shell 133 at least partially covered outside the rib body 132, and the rib shell 133 is detachably connected to the rib body 132. The rib body 132 has an arc-shaped lower end surface 1321, one end of the rib body 132 is connected to the backrest body 121, and the other end extends forward. The base 9 is provided with a matching piece 98 that is slidably matched with the matching rib 13, one of the matching rib 13 and the matching piece 98 is provided with a matching recess 131, and the other of the matching rib 13 and the matching piece 98 is provided with a matching protrusion 981, the matching recess 131 is arc-shaped and extends in the front-rear direction D1, and the matching protrusion 981 is slidably connected in the matching recess 131. Through the sliding connection between the matching protrusion 981 and the matching recess 131, the seat assembly 1 is movably connected to the base 9, and when the seat assembly 1 slides relative to the base 9 along the front-rear direction D1, the angle adjustment between the backrest 12 and the base 9 changes accordingly.

[0071] Continue to refer to Figure 7 , Figure 8 , Fig.10 and Fig.11 , the rib body 132 of the matching rib 13 is provided with a matching recess 131, and the matching piece 98 is provided with a matching protrusion 981. The matching piece 98 includes a rear-end matching piece 98a and a front-end matching piece 98b, and the matching recess 131 includes a rear-end matching recess 131a plugged with the matching protrusion 981 of the rear-end matching piece 98a and a front-end matching recess 131b plugged with the matching protrusion 981 of the front-end matching piece 98b. Among them, the center of the circle of the rear-end matching recess 131a overlaps with the center of the circle of the front-end matching recess 131b, so that the seat assembly 1 can pivot around the same pivot point or the same pivot axis when moving on the base 9, so that the angle adjustment of the backrest 12 relative to the base 9 is more convenient and reliable, and the sliding is smooth.

[0072] Specifically, the rear end engaging recess 131a and the front end engaging recess 131b are respectively provided on opposite sides (ie, left and right sides) of the rib body 132. In the front-to-back direction D1, at least a portion of the front end engaging recess 131b is located in front of the rear end engaging recess 131a.

[0073] In other embodiments not shown, the base 9 is further provided with a matching groove (not shown) extending substantially along the front-rear direction D1, the matching groove is recessed in the upper surface 901 of the base 9 and has an arc-shaped bottom wall, the curvature of the bottom wall of the matching groove is the same as the curvature of the lower end surface 1321 of the rib body 132. The matching groove is located between the front end matching piece 98b and the rear end matching piece 98a (that is, the front end matching piece 98b is located in front of the matching groove, and the rear end matching piece 98a is located behind the matching groove), and the matching rib 13 is slidably connected to the matching groove, so that the movement of the seat assembly 1 along the front-rear direction D1 is more stable and reliable.

[0074] like Figure 6 , Figure 8 , Fig.10 and Fig.11 As shown, in some embodiments, the child carrier 100 also includes an angle adjustment mechanism 2. The angle adjustment mechanism 2 is disposed between the seat assembly 1 and the base 9. The angle adjustment mechanism 2 includes a snap-fitting member 21, a snap-fitting member 23, and an operating member 22. The snap-fitting member 21 is pivotally disposed on one of the seat assembly 1 and the base 9 and is provided with a snap-fitting rod portion 211. The snap-fitting member 23 is disposed on the other of the seat assembly 1 and the base 9 and is sequentially provided with a plurality of snap-fitting recesses 231 along the front-to-back direction D1. Among them, the snap-fitting rod portion 211 can selectively engage with one of the plurality of snap-fitting recesses 231 to limit the seat assembly 1 at a desired angle, and when the snap-fitting member 21 is pivoted to disengage the snap-fitting rod portion 211 from a corresponding one of the plurality of snap-fitting recesses 231, the seat assembly 1 can move relative to the base 9 along the front-to-back direction D1. In this embodiment, as shown in FIG. Figure 7 and Figure 8 As shown, the engaging member 21 is pivotally disposed on the seat assembly 1, and the clamping member 23 is fixedly disposed on the base 9. Fig.10 When the engaging rod 211 engages with the engaging recess 231 located at the rearmost side of the base 9, the inclination angle θ between the backrest 12 and the base 9 is maximum (ie, the seat assembly 1 is in an upright position). Fig.11 When the engaging rod 211 engages with the engaging recess 231 located at the frontmost side of the base 9, the inclination angle θ between the backrest 12 and the base 9 is the smallest (i.e., the seat assembly 1 is in a lying position). Of course, according to actual needs, the engaging member 21 can be set on the base 9 and the engaging member 23 can be set on the seat assembly 1. In other embodiments not shown, the engaging member 23 can be omitted, and a plurality of engaging recesses 231 can be directly set on the base 9 or the seat assembly 1, and this application does not limit this.

[0075] Reference Figure 7 and Figure 8, the engaging member 21 is roughly U-shaped. The engaging member 21 also includes two engaging connection parts 212 connected to the engaging rod part 211, the two engaging connection parts 212 are distributed between the two matching ribs 13, and the middle parts of the two engaging connection parts 212 (i.e., the middle part between the two ends of the engaging connection part 212) are respectively pivotally connected to the corresponding matching ribs 13 through the connecting pin 26, one end of the engaging connection part 212 is connected to the engaging rod part 211, and the other end is pivotally connected to the operating member 22, so that when the user operates the operating member 22 to pivot, the operating member 22 can drive the engaging member 21 to rotate relative to the matching rib 13 around the first rotation axis X. The engaging rod part 211 extends along the substantially left-right direction D2. In order to limit the pivot stroke of the engaging member 21, at least one matching rib 13 is provided with a limiting groove 134, and at least one end of the engaging rod part 211 is penetrated into the limiting groove 134. In this embodiment, the two matching ribs 13 are both provided with limiting grooves 134, and the two ends of the engaging rod 211 are respectively penetrated into the limiting grooves 134. The operating member 22 is connected to the engaging member 21, and specifically, the operating member 22 is connected to one end of the engaging connecting portion 212 away from the engaging rod 211. The operating member 22 is roughly U-shaped, and the operating member 22 is arranged between the base 9 and the cross bar 14. The operating member 22 is roughly U-shaped. The operating member 22 includes an operating portion 221 and two operating drive portions 222 connected to the operating portion 221. Among them, the operating portion 221 is roughly located below the cross bar 14. The middle parts of the two operating drive portions 222 are pivotally connected to the two matching ribs 13 through a pivot shaft 25. Among them, the pivot shaft 25 is roughly parallel to the first rotation axis X and is located in front of the first rotation axis X. One end of the operating drive portion 222 away from the operating portion 221 is connected to the engaging connecting portion 212.

[0076] like Figure 7 , Figure 8 , Fig.10 and Fig.11 As shown, in some embodiments, the angle adjustment mechanism 2 further includes an operation reset member 24, which is disposed between the operating member 22 and the base 9. The operation reset member 24 is, for example, a compression spring, a tension spring, or a spring. One end of the operation reset member 24 abuts against the crossbar 14, and the other end of the operation reset member 24 abuts against the operating portion 221 of the operating member 22. The operation reset member 24 is suitable for biasing the operating member 22 so as to drive the engaging member 21 to rotate in the direction of engaging with the engaging recess 231 through the operating member 22. That is, the operation reset member 24 biases the operating member 22 so that the engaging rod portion 211 of the engaging member 21 moves downward.

[0077] Reference Figure 7 and Figure 8When the angle of the seat assembly 1 needs to be adjusted, the operating portion 221 of the operating member 22 is pulled toward the cross bar 14, and the operating member 22 rotates clockwise around the pivot shaft 25, and drives the engaging member 21 to rotate counterclockwise around the first rotation axis X through the engaging connection portion 212 of the engaging member 21, thereby driving the engaging rod portion 211 to move upward and disengage from the engaging recess 231, so that the matching rib 13 can move in the front-to-back direction relative to the base 9. When the seat assembly 1 is adjusted to the desired angle, the operating member 22 is released, and the operating portion 221 moves downward under the elastic restoring force of the operating reset member 24, and the operating member 22 rotates counterclockwise around the pivot shaft 25, and drives the engaging member 21 to rotate counterclockwise around the first rotation axis X through the engaging connection portion 212 of the engaging member 21, thereby driving the engaging rod portion 211 to move downward and engage with the corresponding engaging recess 231. In this way, the angle adjustment of the seat assembly 1 is achieved.

[0078] According to some embodiments of the present application, the seat position display device 3 is used to prompt the user the degree of inclination of the backrest 12 of the seat assembly 1 relative to the base 9. Figure 3 , Fig.12 and Fig.13 As shown, in some embodiments, the seat position display device 3 includes an indicator 31, a sliding member 39 and a drive connection assembly 32. The sliding member 39 is disposed on the seat assembly 1 and slides as the seat assembly 1 moves. The indicator 31 is rotatably disposed on the base 9. The drive connection assembly 32 is connected to the indicator 31 and the sliding member 39 respectively. Fig.14 , the indicator member 31 is provided with an indicator portion 311, and the indicator portion 311 has a plurality of indicator areas 3111 for indicating the angle between the backrest 12 and the base 9. When the seat assembly 1 moves along the front-to-rear direction D1 relative to the base 9, the sliding member 39 is driven to slide between a first position and a second position relative to the base 9, and the sliding member 39 drives the indicator member 31 to rotate via the driving connection assembly 32, so as to allow the indicator member 31 to synchronously display the indicator area 3111 corresponding to the position of the seat assembly 1. The indicator area 3111 indicates the degree of inclination of the backrest 12 relative to the base 9 with different texts, colors or graphics. In some embodiments, the indicator area 3111 of the indicator member 31 for prompting the user is associated with the position of the engagement recess 231 where the current engagement rod portion 211 is engaged. For example, as Fig.14 As shown, the multiple indication areas 3111 are respectively marked with numbers 1-6. Fig.10 and Fig.17 When the engaging rod 211 engages with the engaging recess 231 at the rearmost side of the base 9, the sliding member 39 is in the first position, and the inclination angle θ between the backrest 12 and the base 9 is the largest (i.e., the seat assembly 1 is in the upright position). At this time, the indicating area 3111 shown to the user by the indicating member 31 is at gear "1". Fig.11and Fig.18 When the engaging rod 211 engages with the engaging recess 231 located at the frontmost side of the base 9, the sliding member 39 is located at the second position, and the inclination angle θ between the backrest 12 and the base 9 is the smallest (i.e., the seat assembly 1 is in a lying position), and the indicating area 3111 shown to the user by the indicator 31 is at the "6" gear. According to the seat position display device 3 provided by the embodiment of the present application, the movement of the seat assembly 1 relative to the base 9 drives the driving connection assembly 32 to move, thereby driving the indicator 31 to rotate to change the indicating area 3111 to be displayed, thereby realizing the synchronous display of the inclination angle θ between the backrest 12 and the base 9 of the seat assembly 1. By rotating the indicator 31 set on the base 9, the space occupied by the indicator 31 can be reduced, and the requirements for the setting position of the indicator 31 can be reduced, and the space restriction of the accommodating cavity 9c of the base 9 on the indicator 31 can be reduced, so that the indicator 31 can be set at a position on the base 9 that is more convenient for observation according to actual needs.

[0079] Continue to refer to Figure 3 , Fig.12 and Fig.13 , the indicator 31 and the drive connection assembly 32 are arranged in the accommodating cavity 9c of the base 9. The base 9 is provided with a sliding groove 96, which penetrates the upper shell 9a of the base 9 and communicates with the accommodating cavity 9c, so as to allow at least a part of the seat assembly 1 to pass through the sliding groove 96 and be connected with the indicator 31 through the drive connection assembly 32. The sliding groove 96 extends roughly along the front-to-back direction D1, and the sliding groove 96 is located between the front end fitting member 98b and the rear end fitting member 98a (that is, the front end fitting member 98b is located in front of the sliding groove 96, and the rear end fitting member 98a is located behind the sliding groove 96). The sliding member 39 is movably inserted in the sliding groove 96 and connected to the drive connection assembly 32. In this embodiment, the sliding member 39 is connected to the matching rib 13. Specifically, the sliding member 39 can be a rib body 132 fixedly connected to the matching rib 13, or a rib body 132 pivotally connected to the matching rib 13, or a rib body 132 integrally formed with the rib body 132 of the matching rib 13.

[0080] like Fig.13 and Fig.14 As shown, the base 9 is provided with an observation port 94 for observing the indication area 3111. The observation port 94 is provided on the upper shell 9a of the base 9 and penetrates the top wall of the accommodating cavity 9c. The observation port 94 corresponds to the position of one of the indication areas 3111. When the indicator 31 rotates, the multiple indication areas 3111 rotate to the observation port 94 in sequence, so that the inclination angle of the backrest 12 relative to the base 9 can be observed in real time.

[0081] Reference Fig.13 and Fig.14In some embodiments, the base 9 is further provided with an observation window 35, which is transparent or translucent and is snapped at the observation port 94. By providing a transparent or translucent observation window 35 at the observation port 94, it is possible to observe the indication area 3111 to be displayed, and to prevent dust, small particles, etc. from falling into the base 9 through the observation port 94. The observation window 35 has an observation portion 351 and an elastic finger portion 352 connected to the end surface of the observation portion 351. The observation portion 351 is roughly square. The elastic finger portion 352 is provided with a snap-fitting protrusion 353. A step portion 941 that is recessed in the direction of the side wall away from the observation port 94 is provided at one end of the observation port 94. The observation portion 351 is snapped to the step portion 941 and covers the observation port 94. The snap-fitting protrusion 353 of the elastic finger portion 352 passes through the observation port 94 and is snapped with the end surface of the upper shell 9a. The observation window 35 can be firmly clamped on the observation port 94 by the elastic finger portion 352 and the step portion 941 , and the observation window 35 can be easily replaced.

[0082] like Figure 12 to Figure 14 In some embodiments, the indicator 31 is, for example, a rotating drum. One end of the rotating drum is formed as an indicating portion 311 and is provided with a plurality of indicating areas 3111. The upper shell 9a of the base 9 is provided with a connecting column 91, and the indicator 31 is sleeved on the connecting column 91, and the connecting column 91 defines the pivot axis R of the indicator 31. Among them, the pivot axis R of the indicator 31 is located outside the sliding range of the sliding member 39 along the sliding groove 96, that is, the lower shell 9b is provided with an abutment rib 97, and the indicator 31 is abutted and limited by the abutment rib 97. Specifically, the indicator 31 also includes an outer peripheral portion 312 and an inner ring portion 314 located in the outer peripheral portion 312. The outer peripheral portion 312 and the inner ring portion 314 are connected to the same side of the indicating portion 311. The inner ring portion 314 is sleeved on the connecting column 91, the outer peripheral portion 312 surrounds the connecting column 91, and the abutment rib 97 abuts against the end surface of the outer peripheral portion 312 away from the indicating portion 311.

[0083] like Fig.14As shown, a plurality of indication areas 3111 are distributed around the pivot axis R of the indicator 31 rotating relative to the base 9. The plurality of indication areas 3111 are respectively identified by numbers. The number of indication areas 3111 is at least two. The number of the engaging recesses 231 on the clamping member 23 is the same as the number of the indication areas 3111. Thus, by engaging the engaging rod 211 with the corresponding engaging recess 231, the seat assembly 1 can be locked at the angles respectively corresponding to the plurality of indication areas 3111. Among them, the more the number of indication areas 3111, the more the number of engaging recesses 231, the more the angles that the seat assembly 1 can adjust, and the closer the angle adjustment of the seat assembly 1 is to stepless adjustment. In this embodiment, the number of indication areas 3111 is, for example, six, and they are identified in sequence by numbers 1-6. In some other embodiments, the indication areas 3111 can be, for example, four, five, etc., which is not limited by the present application.

[0084] like Figure 3 As shown, in some embodiments, the drive connection assembly 32 includes a traction member 321, a first connection terminal 322 connected to a first end of the traction member 321, and a second connection terminal 323 connected to a second end of the traction member 321. The first end of the traction member 321 is connected to the seat assembly 1, and the second end of the traction member 321 is connected to the indicator member 31. The traction member 321 can be wound around the indicator member 31. Specifically, when the indicator member 31 is located at a certain gear position (i.e., the indicator area 3111 marked as the gear position is located at the observation port 94), the traction member 321 is at least partially wound around the indicator member 31. When the seat assembly 1 moves forward and backward relative to the base 9, the effective length L of the traction member 321 changes to allow the indicator member 31 to rotate relative to the base 9. Among them, the effective length L refers to the length of the traction member 321 not wound on the reset member 33, that is, the total length of the traction member 321 minus the length wound on the indicator member 31, that is, the length of the traction member 321 between the first connecting terminal 322 and the tangent point of the traction member 321 and the indicator member 31.

[0085] Specifically, Figure 3As shown, the traction member 321 is connected to the sliding member 39 of the seat assembly 1 through the first connection terminal 322, and is connected to the indicator member 31 through the second connection terminal 323. The indicator member 31 is provided with a first clamping portion 315, and the first clamping portion 315 is located between the outer peripheral portion 312 and the inner ring portion 314. The first clamping portion 315 is provided with a clamping hole 3151, and the clamping hole 3151 extends substantially parallel to the pivot axis R, and the second connection terminal 323 is inserted into the clamping hole 3151. The outer peripheral portion 312 is provided with a limiting groove 313 for winding the traction member 321. At least a portion of the traction member 321 can be wound on the outer peripheral portion 312 and limited in the limiting groove 313. In this way, it is possible to prevent the traction member 321 from slipping off the outer peripheral portion 312; and it is possible to prevent the effective length L of the traction member 321 from changing due to the change in the winding position of the traction member 321 when the seat assembly 1 is adjusted to the same angle in different directions, thereby preventing the indicator member 31 from rotating at different angles, thereby causing different indication areas 3111 to be displayed. In other words, the setting of the limiting groove 313 also plays a role in reducing display errors.

[0086] In some embodiments, Figure 3 , Fig.14 and Fig.15 As shown, the seat position display device 3 further includes a reset member 33, which is connected to the indicator member 31 and the base 9 respectively, and applies a force to the indicator member 31 to rotate the indicator member 31 to wind up the traction member 321. Specifically, in this embodiment, when the seat assembly 1 moves forward relative to the base 9, the sliding member 39 provided on the seat assembly 1 drives the indicator member 31 to rotate through the traction member 321, and the effective length L of the traction member 321 increases; when the seat assembly 1 moves backward relative to the base 9, the reset member 33 biases the indicator member 31 to rotate, and the effective length L of the traction member 321 decreases. Of course, in other embodiments, by changing the position of the indicator member 31 and the biasing direction of the reset member 33, it is also possible to: when the seat assembly 1 moves backward relative to the base 9, the sliding member 39 provided on the seat assembly 1 drives the indicator member 31 to rotate through the traction member 321, and the effective length L of the traction member 321 increases; when the seat assembly 1 moves forward relative to the base 9, the reset member 33 biases the indicator member 31 to rotate, and the effective length L of the traction member 321 decreases.

[0087] Continue to refer to Figure 3 , the reset member 33 is a torsion spring. The first end of the reset member 33 is connected to the connecting column 91, and the second end of the reset member 33 is connected to the indicator 31. The indicator 31 is provided with a second clamping portion 316, and the second clamping portion 316 is located between the inner ring portion 314 and the outer peripheral portion 312. Specifically, the reset member 33 is sleeved on the inner ring portion 314 of the indicator 31, the second end of the reset member 33 is clamped to the second clamping portion 316, and the first end of the reset member 33 is clamped to the connecting column 91.

[0088] like Figure 3 , Fig.15 and Fig.16 As shown, the seat position display device 3 further includes a guide mechanism 34. The first end of the traction member 321 is connected to the seat assembly 1, and the second end of the traction member 321 is connected to the indicator member 31. The middle part between the first end and the second end of the traction member 321 abuts against the guide mechanism 34 to change the shape of the traction member 321, so as to allow the extension direction of the traction member 321 to be changed. By changing the extension direction of the traction member 321 through the guide mechanism 34, the indicator member 31 can be set at a suitable position (for example, at a position close to the middle of the sliding groove 96) as needed, so that the indicator member 31 can be arranged more freely and reasonably. In this embodiment, the indicator member 31 is roughly distributed at a position corresponding to the middle of the sliding groove 96 in the front-to-back direction D1, that is, roughly distributed in the middle of the base 9, so as to facilitate viewing of the displayed indication area 3111.

[0089] In some embodiments, Figure 3 As shown, the guide mechanism 34 includes a sheath 342 fixedly arranged on the base 9, and the traction member 321 is inserted into the sheath 342 and can slide relative to the sheath 342. The sheath 342 is roughly U-shaped, used to guide the movement direction of the traction member 321 and make the movement of the traction member 321 smoother. Specifically, the part of the traction member 321 located in the sheath 342 at least partially abuts against the inner wall of the sheath 342 and changes in shape with the sheath 342 (that is, the middle part of the traction member 321 between the first end and the second end abuts the guide mechanism 34 to change the shape of the traction member 321). Among them, the bottom surface of the upper shell 9a of the base 9 is provided with a first limiting portion 92 and a second limiting portion 93. Exemplarily, the traction member 321 is a flexible steel wire; the sheath 342 is a plastic wire sleeve; the first limiting portion 92 and the second limiting portion 93 are limiting grooves or buckles. One end of the sheath 342 is connected to the first limiting portion 92 , and the other end of the sheath 342 is connected to the second limiting portion 93 .

[0090] Continue to refer to Figure 3, the movement direction of the traction member 321 at the first limit portion 92 and the movement direction at the second limit portion 93 are not parallel to each other. Specifically, the angle between the movement direction of the traction member 321 at the first limit portion 92 and the movement direction at the second limit portion 93 is between 90° and 270°. In other words, the traction member 321 includes a first traction segment 3211 and a second traction segment 3212, and the guide mechanism 34 is located between the first traction segment 3211 and the second traction segment 3212. The first traction segment 3211 and the second traction segment 3212 are both in a straight line stretching state. The first traction segment 3211 is a straight segment of the traction member 321 located between the sheath 342 of the guide mechanism 34 (i.e., the open end of the sheath 342 on the side close to the sliding member 39) and the sliding member 39, and the second traction segment 3212 is a straight segment of the traction member 321 located between the sheath 342 of the guide mechanism 34 (i.e., the open end of the sheath 342 on the side away from the sliding member 39) and the indicator 31. The angle between the first traction section 3211 and the second traction section 3212 is greater than 90 degrees and less than 270 degrees. In this embodiment, the angle between the movement direction of the traction member 321 at the first limit portion 92 and the movement direction at the second limit portion 93 is approximately 180 degrees. As a result, the projection of the indicator 31 on the plane where the sliding groove 96 is located overlaps with a part of the sliding groove 96, so that the seat position display device is more compact in the front-to-back direction D1. In this embodiment, the upper shell 9a is provided with a positioning portion 99. The lower shell 9b is covered with the upper shell 9a, and the bolt passes through the lower shell 9b and is connected to the positioning portion 99. The extension direction of the first traction section 3211 is parallel to the movement direction of the sliding member 39. Among them, the movement direction of the sliding member 39 is parallel to the extension direction of the sliding groove 96.

[0091] In some other embodiments not shown, the guide mechanism 34 includes a guide groove formed by the upper shell 9a (not shown in the drawings). This embodiment is mainly different from the above embodiment in the following ways. The traction member 321 passes through the guide groove and can slide along the guide groove. Among them, the part of the traction member 321 located in the guide groove at least partially abuts against the inner wall of the guide groove to change the shape of the traction member 321 (that is, the middle part of the traction member 321 between the first end and the second end abuts against the guide mechanism 34 to change the shape of the traction member 321). The traction member 321 has a first traction segment 3211 and a second traction segment 3212 passing through the guide groove. Among them, the angle between the first traction segment 3211 and the second traction segment 3212 (that is, the movement direction of the first traction segment 3211 and the movement direction of the second traction segment 3212) is greater than 90 degrees and less than 270 degrees. Specifically, the angle between the two is approximately 180 degrees. The extension direction of the first traction segment 3211 is parallel to the movement direction of the sliding member 39.

[0092] In other embodiments, Fig.15 and Fig.16 As shown, the guide mechanism 34 may include a pulley 341 or a guide block (not shown in the drawings). In this embodiment, the guide mechanism 34 includes a pulley 341, and specifically, the pulley 341 is, for example, a fixed pulley. The traction member 321 may be a metal wire, a chain, a webbing, a nylon rope, or a bendable flexible plastic sheet, etc. The traction member 321 includes a first traction segment 3211 and a second traction segment 3212, respectively, and the guide mechanism 34 (i.e., the pulley 341) is located between the first traction segment 3211 and the second traction segment 3212. The first traction segment 3211 and the second traction segment 3212 are both in a straight stretching state. The first traction segment 3211 is a straight segment of the traction member 321 located between the pulley 341 and the sliding member 39 and just in contact with the two, and the second traction segment 3212 is a straight segment of the traction member 321 located between the pulley 341 and the indicating member 31 and just in contact with the two. The first end of the traction member 321 is connected to the sliding member 39, and the second end of the traction member 321 is connected to the indicator member 31 by bypassing the pulley 341 (that is, the first end of the traction member 321 is connected to the sliding member 39, the second end of the traction member 321 is connected to the indicator member 31, and the middle part between the first end and the second end abuts against the pulley 341 to change the shape of the traction member 321), so that the movement direction of the traction member 321 pulled by the sliding member 39 is not parallel to the movement direction of the traction member 321 pulling the indicator member 31 (the movement direction is tangent to the outer periphery of the indicator member 31) (that is, the movement direction of the first traction segment 3211 and the movement direction of the second traction segment 3212 are not parallel to each other), and the extension direction of the first traction segment 3211 is substantially parallel to the movement direction of the sliding member 39. In this way, the extension direction of the traction member 321 can also be changed. Specifically, the angle between the first traction segment 3211 and the second traction segment 3212 (ie, the movement direction of the first traction segment 3211 and the movement direction of the second traction segment 3212) is greater than 90 degrees and less than 270 degrees. More specifically, the angle between the two is approximately 180 degrees.

[0093] Of course, in other embodiments, such as Fig.17 and Fig.18 As shown, the guide mechanism 34 may not be provided, and the indicator 31 may be provided on the extension line of the sliding groove 96 in the front-rear direction D1 or near the extension line of the sliding groove 96. It should be noted that the indicator 31 is provided on the extension line of the sliding groove 96, which means that the extension line of the sliding groove 96 is substantially tangent to the outer periphery of the indicator 31.

[0094] According to the seat position display device 3 provided by some of the above embodiments of the present application, the sliding member 39 is driven to slide by the seat assembly 1 moving relative to the base 9, and the sliding member 39 drives the indicator 31 to rotate through the traction member 321 to display the position of the seat assembly 1 in real time. As a result, the setting of the indicator 31 is more flexible, less restricted by the space of the base 9, and it is more convenient to view the displayed indicator area 3111 during the process of adjusting the angle of the seat assembly 1.

[0095] It should be noted that, in one or more of the above embodiments, the seat position display device 3 may also be used to display the sliding position of the seat assembly 1 relative to the base 9 in the horizontal direction. Fig.19 and Fig. 20 FIG. 1 shows a seat position display device for a child carrier according to some other embodiments of the present application. The child carrier may be Figure 1 and Figure 2 The child carrier 100 shown in the figure includes a base 9 and a seat assembly 1. A horizontal guide rail (not shown in the drawings) is provided on the base 9. The seat assembly can slide horizontally relative to the base along the horizontal guide rail. The seat position display device 3 includes an indicator 31 provided on the base, a sliding member 39 provided on the seat assembly, and a driving connection assembly 32 connecting the indicator 31 and the sliding member 39. The indicator 31 is connected to the sliding member 39 through the driving connection assembly 32. When the sliding member 39 slides relative to the sliding groove 96 of the base 9, the indicator 31 is driven to slide relative to the base 9, thereby changing the indication area 3111 displayed at the observation window 35. Among them, the indicator 31 is roughly in the shape of a long strip, and the extension direction of the indicator 31 is roughly parallel to the extension direction of the sliding groove 96, and a plurality of indication areas 3111 are provided. The sliding member 39 has a sliding range along the sliding groove 96 in the front-to-back direction D1. Referring to Fig.19 As shown in FIG. 1 , when the child carrier is in gear “1”, the seat assembly is located at the rearmost portion of the sliding range in the front-rear direction D1 (ie, the sliding member 39 is located at the first position). Fig. 20 As shown in FIG. 1 , when the child carrier is in gear “8”, the seat assembly is located at the frontmost portion of the sliding range in the front-rear direction D1 (ie, the sliding member 39 is located at the second position). Fig. 20 It can be seen that the base 9 needs to provide a storage space twice the length of the sliding groove 96 in the front-to-back direction D1 to accommodate the seat position display device, while less storage space is required in the left-right direction. In this application, the direction that the child faces when the child sits in the seat assembly is the forward direction, and the direction that the child faces away when the child sits in the seat assembly is the backward direction. The front end refers to the part close to the front side of the base 9 in the front-to-back direction, and the rear end refers to the part close to the rear side of the base 9 in the front-to-back direction.

[0096] By using the seat position display device according to the embodiment of the present invention, it is possible to observe in real time whether the seat position is adjusted in place when the seat position is adjusted, and the structure of the seat position display device is simple.

[0097] According to the seat position display device and the child carrier with the seat position display device provided by the embodiment of the present invention, the movement of the seat assembly relative to the base drives the driving connection assembly to move, thereby driving the indicator to rotate to change the indication area to be displayed, thereby realizing synchronous display of the angle between the backrest of the seat assembly and the base. By rotating the indicator arranged on the base, the space occupied by the indicator can be reduced, and the requirements of the indicator on the setting position can be reduced, and the space restriction of the accommodating cavity of the base on the indicator can be reduced, so that the indicator can be arranged at a position on the base that is more convenient for observation according to actual needs.

[0098] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0099] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
