[0068] Figures 1 to 3 This illustration shows a perspective view of a child vehicle 100 according to some embodiments of the present invention. The child vehicle 100 may be, for example, a child safety seat or a stroller. The following description uses a child safety seat as an example. The child safety seat can be secured to a car seat via, for example, its own ISOFIX connectors or a pull strap, or via the car's seatbelt. The child safety seat can be installed forward-facing or rear-facing on the car seat.

[0069] 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 according to some embodiments of the present invention. The seat assembly 1 is provided with a backrest 12, and the seat assembly 1 is movable relative to the base 9 in a front-rear direction D1, allowing the backrest 12 to be angularly adjustable relative to the base 9. Specifically, the seat assembly 1 moves relative to the base 9 along an arc, and this arc-shaped movement has a motion component in the front-rear direction D1. Thus, when the seat assembly 1 moves relative to the base 9 in the front-rear direction D1, the tilt angle θ of the seat assembly 1 relative to the base changes accordingly. The seat position display device 3 is used to indicate the tilt angle θ of the seat assembly 1 relative to the base 9. Specifically, as... Figure 10 and Figure 11As shown, the tilt angle θ can be the angle between the plane containing the backrest body 121 of the backrest 12 and the plane containing the contact surface of the base 9 and the car seat. The seat position display device 3 will be described along with the child vehicle 100 below.

[0070] Combined with reference Figure 10 and Figure 11 In some embodiments, the base 9 includes an upper housing 9a and a lower housing 9b connected to the upper housing 9a, the upper housing 9a and the lower housing 9b forming a receiving cavity 9c. The seat assembly 1 is disposed on the upper housing 9a and is movable relative to the upper housing 9a in the front-rear direction D1. The surface of the upper housing 9a forms the upper surface 901 of the base 9. The upper surface 901 of the base 9 is an arcuate surface, specifically, the upper surface 901 is an arcuate convex surface that is higher in the middle and lower around the edges. The surface of the lower housing 9b forms the lower surface 902 of the base 9, the lower surface 902 is a generally flat surface or an arcuate concave surface that is recessed in the middle towards the receiving cavity 9c, so as to facilitate the stable placement of the child carrier 100 on the car seat.

[0071] Combined with reference Figures 6 to 7 The seat assembly 1 includes a seat body 11 and a backrest 12. The backrest 12 has two mating ribs 13 extending generally along the front-rear direction D1 and crossbars 14 respectively connected to the two mating ribs 13. The seat body 11 is for a child to sit on. In some embodiments, such as Figure 6 As shown, the seat body 11 is a booster seat, detachably connected to the backrest 12. The seat body 11 is snapped onto two mating ribs 13 and detachably connected to a crossbar 14. The seat body 11 can be assembled with the backrest 12 as a child safety seat, or used alone as a booster seat. The backrest 12 also includes a backrest body 121, with each mating rib 13 connected to the backrest body 121 and extending away from the backrest body 121 in the front-back direction D1. Each mating rib 13 can slide along the front-back direction D1 to the base 9, causing the backrest 12 to move relative to the base 9, thereby changing the tilt angle θ between the backrest 12 and the base 9. The two mating ribs 13 can both slide relative to the base 9 and provide stable support on the base 9. In some embodiments, the seat body 11 and the backrest 12 are a single piece. An exemplary seat assembly 1 is an infant carrier. The seat body 11 and the backrest 12 are integrally molded from polyethylene material. The lower part of the infant carrier is provided with two connecting rods, which are detachably connected to the base 9 and can slide back and forth relative to the base 9. In some other embodiments, the seat body 11 is slidably connected to the base 9. When the seat body 11 slides relative to the base 9, the angle between the plane on which the seat body 11 is located and the plane on which the contact surface between the base 9 and the car seat is located changes with the position of the seat body 11.

[0072] For ease of description, the following explanation will use the mating rib 13 located on the left side as an example.

[0073] like Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, the mating rib 13 includes a rib body 132 and a rib shell 133 that at least partially covers the rib body 132. The rib shell 133 is detachably connected to the rib body 132. The rib body 132 has an arc-shaped lower end face 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 mating member 98 that slides with the mating rib 13. One of the mating rib 13 and the mating member 98 is provided with a mating recess 131, and the other of the mating rib 13 and the mating member 98 is provided with a mating protrusion 981. The mating recess 131 is arc-shaped and extends in the front-rear direction D1. The mating protrusion 981 is slidably connected to the mating recess 131. Through the sliding connection between the mating protrusion 981 and the mating recess 131, the seat assembly 1 is movably connected to the base 9. When the seat assembly 1 slides relative to the base 9 in the front-rear direction D1, the angle adjustment between the backrest 12 and the base 9 changes accordingly.

[0074] Continue to refer to Figure 7 , Figure 8 , Figure 10 and Figure 11 The rib body 132 of the mating rib 13 is provided with a mating recess 131, and the mating member 98 is provided with a mating protrusion 981. The mating member 98 includes a rear mating member 98a and a front mating member 98b. The mating recess 131 includes a rear mating recess 131a that engages with the mating protrusion 981 of the rear mating member 98a and a front mating recess 131b that engages with the mating protrusion 981 of the front mating member 98b. The center of the rear mating recess 131a and the center of the front mating recess 131b are overlapped, so that when the seat assembly 1 moves on the base 9, it can pivot around the same pivot point or the same pivot axis, thereby making the angle adjustment of the backrest 12 relative to the base 9 more convenient, reliable, and smooth.

[0075] Specifically, the rear end mating recess 131a and the front end mating recess 131b are respectively disposed on opposite sides (i.e., left and right sides) of the rib body 132. In the front-rear direction D1, at least a portion of the front end mating recess 131b is located in front of the rear end mating recess 131a.

[0076] In other embodiments not shown, the base 9 is further provided with a mating groove (not shown) extending generally along the front-rear direction D1. The mating groove is recessed into the upper surface 901 of the base 9 and has an arc-shaped bottom wall. The arc of the bottom wall of the mating groove is the same as the arc of the lower end face 1321 of the rib body 132. The mating groove is located between the front mating member 98b and the rear mating member 98a (i.e., the front mating member 98b is located in front of the mating groove, and the rear mating member 98a is located behind the mating groove). The mating rib 13 is slidably connected to the mating groove, so that the movement of the seat assembly 1 along the front-rear direction D1 is more stable and reliable.

[0077] like Figure 6 , Figure 8 , Figure 10 and Figure 11 As shown, in some embodiments, the child vehicle 100 further 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 an engaging member 21, a locking member 23, and an operating member 22. The engaging member 21 is pivotally disposed on one of the seat assembly 1 and the base 9 and is provided with an engaging lever portion 211. The locking member 23 is disposed on the other of the seat assembly 1 and the base 9 and is provided with a plurality of engaging recesses 231 sequentially along the front-rear direction D1. The engaging lever portion 211 can selectively engage with one of the plurality of engaging recesses 231 to limit the seat assembly 1 to a desired angle, and when the engaging member 21 pivots to disengage the engaging lever portion 211 from the corresponding one of the plurality of engaging recesses 231, the seat assembly 1 can move relative to the base 9 along the front-rear direction D1. In this embodiment, as... Figure 7 and Figure 8 As shown, the engaging member 21 is pivotally mounted on the seat assembly 1, and the fastener 23 is fixedly mounted on the base 9. (Refer to...) Figure 10 When the engaging rod 211 engages with the engaging recess 231 located on the rearmost side of the base 9, the tilt angle θ between the backrest 12 and the base 9 is at its maximum (i.e., the seat assembly 1 is in an upright position). (Refer to...) Figure 11 When the engaging rod 211 engages with the engaging recess 231 located at the foremost side of the base 9, the tilt angle θ between the backrest 12 and the base 9 is minimized (i.e., the seat assembly 1 is in a lying position). Of course, depending on actual needs, the engaging member 21 can be disposed on the base 9 while the engaging member 23 is disposed on the seat assembly 1. In some other embodiments not shown, the engaging member 23 may not be provided; instead, multiple engaging recesses 231 may be directly provided on the base 9 or the seat assembly 1. This application does not impose any restrictions on this.

[0078] Reference Figure 7 and Figure 8The engaging member 21 is generally U-shaped. The engaging member 21 also includes two engaging connecting portions 212 connected to the engaging rod portion 211. The two engaging connecting portions 212 are distributed between the two mating ribs 13, and the middle portion of each engaging connecting portion 212 (i.e., the middle part located between the two ends of the engaging connecting portion 212) is pivotally connected to the corresponding mating rib 13 via connecting pins 26. One end of the engaging connecting portion 212 is connected to the engaging rod portion 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 mating rib 13 about a first rotation axis X. The engaging rod portion 211 extends in a generally left-right direction D2. To limit the pivoting stroke of the engaging member 21, at least one mating rib 13 is provided with a limiting groove 134, and at least one end of the engaging rod portion 211 passes through the limiting groove 134. In this embodiment, both mating ribs 13 are provided with limiting grooves 134, and both ends of the engaging rod portion 211 pass through the limiting grooves 134 respectively. The operating member 22 is connected to the engaging member 21; specifically, the operating member 22 is connected to the end of the engaging connection portion 212 away from the engaging rod portion 211. The operating member 22 is generally U-shaped and is disposed between the base 9 and the crossbar 14. The operating member 22 is generally U-shaped. The operating member 22 includes an operating part 221 and two operating drive parts 222 connected to the operating part 221. The operating part 221 is generally located below the crossbar 14. The middle portions of the two operating drive parts 222 are pivotally connected to the two mating ribs 13 via a pivot shaft 25. The pivot shaft 25 is generally parallel to the first rotation axis X and located in front of the first rotation axis X. The end of the operating drive part 222 away from the operating part 221 is connected to the engaging connection portion 212.

[0079] like Figure 7 , Figure 8 , Figure 10 and Figure 11 As shown, in some embodiments, the angle adjustment mechanism 2 further includes an operation reset member 24, which is disposed between the operation member 22 and the base 9. The operation reset member 24 is, for example, a compression spring, a tension spring, or a spring sheet. 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 operation portion 221 of the operation member 22. The operation reset member 24 is adapted to bias the operation member 22 so that the engagement member 21 is rotated in the direction of engaging with the engagement recess 231 via the operation member 22. That is, the operation reset member 24 biases the operation member 22 so that the engagement rod portion 211 of the engagement member 21 moves downward.

[0080] Reference Figure 7 and Figure 8When the angle of seat assembly 1 needs to be adjusted, the operating part 221 of the operating member 22 is pulled towards the crossbar 14. The operating member 22 rotates clockwise around the pivot axis 25, and through the engaging connection part 212 of the engaging member 21, it drives the engaging member 21 to rotate counterclockwise around the first rotation axis X. This causes the engaging rod part 211 to move upward and disengage from the engaging recess 231, allowing the mating rib 13 to move relative to the base 9 in the front-back direction. When the seat assembly 1 is adjusted to the desired angle, the operating member 22 is released. The operating part 221 moves downward under the elastic restoring force of the operating reset member 24. The operating member 22 rotates counterclockwise around the pivot axis 25, and through the engaging connection part 212 of the engaging member 21, it drives the engaging member 21 to rotate counterclockwise around the first rotation axis X. This causes the engaging rod part 211 to move downward and engage with the corresponding engaging recess 231. In this way, the angle adjustment of seat assembly 1 is achieved.

[0081] According to some embodiments of this application, the seat position display device 3 is used to indicate to the user the degree of tilt of the backrest 12 of the seat assembly 1 relative to the base 9. For example... Figure 3 , Figure 12 and Figure 13 As shown, in some embodiments, the seat position display device 3 includes an indicator 31, a slider 39, and a drive connection assembly 32. The slider 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 slider 39 respectively. (Referring to reference...) Figure 14 The indicator 31 is provided with an indicator portion 311, which has multiple indicator areas 3111 for indicating the angle between the backrest 12 and the base 9. When the seat assembly 1 moves relative to the base 9 in the fore-and-aft direction D1, it causes the slider 39 to slide relative to the base 9 between a first position and a second position. The slider 39 drives the indicator 31 to rotate via the drive connection assembly 32, allowing the indicator 31 to simultaneously display the indicator areas 3111 corresponding to the position of the seat assembly 1. The indicator areas 3111 use different text, colors, or graphics to indicate the degree of inclination of the backrest 12 relative to the base 9. In some embodiments, the indicator areas 3111 of the indicator 31 used to prompt the user are associated with the position of the engagement recess 231 where the current engagement lever portion 211 is engaged. For example, Figure 14 As shown, multiple indicator areas 3111 are labeled with numbers 1-6 respectively. (Refer to reference...) Figure 10 and Figure 17 When the engaging rod 211 engages with the engaging recess 231 located on the rearmost side of the base 9, the sliding member 39 is in the first position, and the tilt angle θ between the backrest 12 and the base 9 is at its maximum (i.e., the seat assembly 1 is in an upright position). At this time, the indicator area 3111 shown by the indicator 31 to the user is at position "1". (Refer to reference...) Figure 11and Figure 18 When the engaging rod 211 engages with the engaging recess 231 located at the foremost side of the base 9, the sliding member 39 is in the second position, and the tilt angle θ between the backrest 12 and the base 9 is at its minimum (i.e., the seat assembly 1 is in a flat position). At this time, the indicator area 3111 shown by the indicator 31 to the user is at position "6". According to the seat position display device 3 provided in the embodiment of this application, the movement of the seat assembly 1 relative to the base 9 drives the drive connecting assembly 32 to move, thereby driving the indicator 31 to rotate to change the indicator area 3111 to be displayed, thereby synchronously displaying the tilt 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. The space restriction of the receiving cavity 9c of the base 9 on the indicator 31 can be reduced, so that the indicator 31 can be set on the base 9 in a more convenient position according to actual needs.

[0082] Continue to refer to Figure 3 , Figure 12 and Figure 13 The indicator 31 and the drive connection assembly 32 are disposed in the receiving cavity 9c of the base 9. The base 9 is provided with a sliding groove 96, which penetrates the upper housing 9a of the base 9 and communicates with the receiving cavity 9c, so as to allow at least a portion of the seat assembly 1 to pass through the sliding groove 96 and be connected to the indicator 31 through the drive connection assembly 32. The sliding groove 96 extends generally in the front-rear direction D1 and is located between the front mating member 98b and the rear mating member 98a (i.e., the front mating member 98b is located in front of the sliding groove 96, and the rear mating member 98a is located behind the sliding groove 96). The sliding member 39 is movably inserted into the sliding groove 96 and connected to the drive connection assembly 32. In this embodiment, the sliding member 39 is connected to the mating rib 13. Specifically, the sliding member 39 may be a rib body 132 fixedly connected to the mating rib 13, or a rib body 132 pivotally connected to the mating rib 13, or an integrally formed structure with the rib body 132 of the mating rib 13.

[0083] like Figure 13 and Figure 14 As shown, the base 9 is provided with an observation port 94 for observing the indicator area 3111. The observation port 94 is located in the upper housing 9a of the base 9 and penetrates the top wall of the receiving cavity 9c. The observation port 94 corresponds to the position of one of the indicator areas 3111. When the indicator 31 rotates, the multiple indicator areas 3111 rotate sequentially to the observation port 94, so that the tilt angle of the backrest 12 relative to the base 9 can be observed in real time.

[0084] Reference Figure 13 and Figure 14In some embodiments, the base 9 is further provided with an observation window 35, which is transparent or semi-transparent and is snapped into the observation port 94. By providing a transparent or semi-transparent observation window 35 at the observation port 94, the indicator area 3111 to be displayed can be observed, while preventing 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 face of the observation portion 351. The observation portion 351 is generally square. The elastic finger portion 352 is provided with an engaging protrusion 353. One end of the observation port 94 is provided with a stepped portion 941 that is recessed toward the side wall away from the observation port 94. The observation portion 351 is snapped into the stepped portion 941 and covers the observation port 94. The engaging protrusion 353 of the elastic finger portion 352 passes through the observation port 94 and is snapped into the end face of the upper housing 9a. The observation window 35 can be securely attached to the observation port 94 by means of the flexible finger portion 352 and the step portion 941, and it is also convenient to replace the observation window 35.

[0085] like Figures 12 to 14 In some embodiments, the indicator 31 is, for example, a rotating drum. One end of the drum is formed as an indicator portion 311 and is provided with a plurality of indicator areas 3111. The upper housing 9a of the base 9 is provided with a connecting post 91, and the indicator 31 is sleeved on the connecting post 91, which defines the pivot axis R of the indicator 31. The pivot axis R of the indicator 31 is located outside the sliding range (also known as the sliding trajectory) of the slider 39 along the sliding groove 96, that is, the lower housing 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 within the outer peripheral portion 312. The outer peripheral portion 312 and the inner ring portion 314 are connected to the same side of the indicator portion 311. The inner ring 314 is fitted onto the connecting post 91, and the outer peripheral portion 312 surrounds the connecting post 91. The abutting rib 97 abuts against the end face of the outer peripheral portion 312 away from the indicator portion 311.

[0086] like Figure 14As shown, multiple indicator areas 3111 are distributed around the pivot axis R of the indicator 31 relative to the base 9. Each indicator area 3111 is numbered. The number of indicator areas 3111 is at least two. The number of engagement recesses 231 on the locking member 23 is the same as the number of indicator areas 3111. Thus, by engaging the locking rod 211 with the corresponding engagement recess 231, the seat assembly 1 can be locked at the angles corresponding to the multiple indicator areas 3111. The more indicator areas 3111 and the more engagement recesses 231 there are, the more angles the seat assembly 1 can be adjusted, and the closer the angle adjustment of the seat assembly 1 is to stepless adjustment. In this embodiment, the number of indicator areas 3111 is, for example, six, and they are sequentially identified by numbers 1-6. In other embodiments, the indicator areas 3111 may be, for example, four or five, etc., and this application does not impose any limitations on this.

[0087] 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 31. The traction member 321 is capable of being wound around the indicator 31; specifically, when the indicator 31 is in a certain position (i.e., the indicator area 3111 marked as the position is located at the observation port 94), the traction member 321 is at least partially wound around the indicator 31. When the seat assembly 1 moves back and forth relative to the base 9, the effective length L of the traction member 321 changes to allow the indicator 31 to rotate relative to the base 9. Wherein, the effective length L refers to the length of the traction member 321 that is not wound around the reset member 33, that is, the total length of the traction member 321 minus the length wound around the indicator member 31, which is also the length of the traction member 321 from the first connecting terminal 322 to the tangent point between the traction member 321 and the indicator member 31.

[0088] Specifically, if Figure 3As shown, the traction member 321 is connected to the sliding member 39 of the seat assembly 1 via a first connecting terminal 322, and to the indicator member 31 via a second connecting terminal 323. The indicator member 31 has a first engaging portion 315 located between the outer peripheral portion 312 and the inner ring portion 314. The first engaging portion 315 has an engaging hole 3151 extending substantially parallel to the pivot axis R, and the second connecting terminal 323 is inserted into the engaging hole 3151. The outer peripheral portion 312 has a limiting groove 313 for winding the traction member 321. At least a portion of the traction member 321 can be wound around the outer peripheral portion 312 and limited within the limiting groove 313. In this way, it can prevent the traction member 321 from slipping off the outer peripheral portion 312; and it can also 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, which would result in different rotation angles of the indicator 31 and thus different display areas 3111. In other words, the setting of the limiting groove 313 also plays a role in reducing display errors.

[0089] In some embodiments, as Figure 3 , Figure 14 and Figure 15 As shown, the seat position display device 3 also includes a reset member 33, which is connected to the indicator 31 and the base 9 respectively, and applies a force to the indicator 31 to rotate it and wrap around the traction member 321. Specifically, in this embodiment, when the seat assembly 1 moves forward relative to the base 9, the sliding member 39 disposed on the seat assembly 1 drives the indicator 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 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 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 disposed on the seat assembly 1 drives the indicator 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 31 to rotate, and the effective length L of the traction member 321 decreases.

[0090] In some embodiments, the reset element 33 of this application may be a resilient reset element. (Continue referring to...) Figure 3The reset element 33 is a torsion spring. The first end of the reset element 33 is connected to the connecting post 91, and the second end of the reset element 33 is connected to the indicator element 31. The indicator element 31 is provided with a second engaging portion 316, which is located between the inner ring portion 314 and the outer peripheral portion 312. Specifically, the reset element 33 is sleeved on the inner ring portion 314 of the indicator element 31, the second end of the reset element 33 is engaged with the second engaging portion 316, and the first end of the reset element 33 is engaged with the connecting post 91.

[0091] like Figure 3 , Figure 15 and Figure 16 As shown, the seat position display device 3 also includes a guide mechanism 34. A first end of the traction member 321 is connected to the seat assembly 1, and a second end of the traction member 321 is connected to the indicator member 31. The middle portion of the traction member 321 between the first and second ends abuts against the guide mechanism 34, causing a change in the shape of the traction member 321. This allows for a change in the extension direction of the traction member 321, and causes the pivot axis R of the indicator member 31 to deviate from the extension line of the sliding trajectory of the slider 39. By changing the extension direction of the traction member 321 through the guide mechanism 34, the indicator member 31 can be positioned appropriately as needed (e.g., near the center of the sliding groove 96), allowing for a more flexible and reasonable arrangement of the indicator member 31. In this embodiment, the indicator members 31 are approximately distributed in the front-rear direction D1 at positions corresponding to the center of the sliding groove 96, i.e., approximately in the center of the base 9, to facilitate viewing the displayed indicator area 3111.

[0092] In some embodiments, as Figure 3 As shown, the guide mechanism 34 includes a sleeve 342 fixedly mounted on the base 9, and a traction member 321 passing through the sleeve 342 and capable of sliding relative to the sleeve 342. The sleeve 342 is generally U-shaped and is used to guide the movement direction of the traction member 321, making the movement of the traction member 321 smoother. Specifically, the portion of the traction member 321 located inside the sleeve 342 at least partially abuts against the inner wall of the sleeve 342 and changes shape with the sleeve 342 (that is, the middle portion of the traction member 321 between the first end and the second end abuts against the guide mechanism 34, causing the traction member 321 to change shape). A first limiting portion 92 and a second limiting portion 93 are provided on the bottom surface of the upper housing 9a of the base 9. Exemplarily, the traction member 321 is a flexible steel wire; the sleeve 342 is a plastic wire sleeve; and 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 part 92, and the other end of the sheath 342 is connected to the second limiting part 93.

[0093] Continue to refer to Figure 3The direction of movement of the traction member 321 at the first limiting portion 92 and the direction of movement at the second limiting portion 93 are not parallel to each other. Specifically, the angle between the direction of movement of the traction member 321 at the first limiting portion 92 and the direction of movement at the second limiting 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. Both the first traction segment 3211 and the second traction segment 3212 are in a straight-line stretched state. The first traction segment 3211 is a straight segment of the traction member 321 located between the sleeve 342 of the guide mechanism 34 (i.e., the open end of the sleeve 342 near the slider 39) and the slider 39, and the second traction segment 3212 is a straight segment of the traction member 321 located between the sleeve 342 of the guide mechanism 34 (i.e., the open end of the sleeve 342 away from the slider 39) and the indicator 31. The angle between the first traction segment 3211 and the second traction segment 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 limiting part 92 and the movement direction at the second limiting part 93 is approximately 180°. Therefore, the projection of the indicator 31 onto the plane of the sliding groove 96 overlaps with a portion of the sliding groove 96, making the seat position display device more compact in the front-rear direction D1. In this embodiment, the upper housing 9a is provided with a positioning part 99. The lower housing 9b fits into the upper housing 9a, and a bolt passes through the lower housing 9b and connects to the positioning part 99. The extension direction of the first traction segment 3211 is parallel to the movement direction of the sliding member 39. The movement direction of the sliding member 39 is parallel to the extension direction of the sliding groove 96.

[0094] In some other embodiments not shown, the guide mechanism 34 includes a guide groove (not shown) formed by the upper housing 9a. This embodiment differs from the above embodiments primarily in the following ways: The traction member 321 passes through the guide groove and is slidable along it. The portion of the traction member 321 located within the guide groove at least partially abuts against the inner wall of the guide groove, causing a change in shape in the traction member 321 (i.e., the middle portion of the traction member 321 between the first and second ends abuts against the guide mechanism 34, causing a change in shape in the traction member 321). The traction member 321 has a first traction segment 3211 and a second traction segment 3212 extending out of the guide groove. The angle between the first traction segment 3211 and the second traction segment 3212 (i.e., between the direction of movement of the first traction segment 3211 and the direction of movement of the second traction segment 3212) is greater than 90 degrees and less than 270 degrees; specifically, the angle is approximately 180 degrees. The extension direction of the first traction segment 3211 is parallel to the direction of movement of the slider 39.

[0095] In other embodiments, such as Figure 15 and Figure 16 As shown, the guiding mechanism 34 may include a pulley 341 or a guide block (not shown in the figures). In this embodiment, the guiding mechanism 34 includes a pulley 341, specifically, the pulley 341 is, for example, a fixed pulley. The traction member 321 may be a metal wire, chain, webbing, nylon rope, or a flexible plastic sheet, etc. The traction member 321 includes a first traction section 3211 and a second traction section 3212 respectively, and the guiding mechanism 34 (i.e., the pulley 341) is located between the first traction section 3211 and the second traction section 3212. Both the first traction section 3211 and the second traction section 3212 are in a straight stretched state. The first traction section 3211 is a straight section of the traction member 321 located between the pulley 341 and the sliding member 39 and in just contact with both, and the second traction section 3212 is a straight section of the traction member 321 located between the pulley 341 and the indicator 31 and in just contact with both. The first end of the traction member 321 is connected to the sliding member 39, and the second end of the traction member 321 passes over the pulley 341 and connects to the indicator 31 (i.e., 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 31, and the middle part between the first end and the second end abuts against the pulley 341, causing a change in the shape of the traction member 321). This results in the traction member 321 moving in a direction pulled by the sliding member 39, which is not parallel to the direction of movement of the traction member 321 pulling the indicator 31 (this direction of movement is tangent to the outer periphery of the indicator 31). This also results in the first traction segment 3211 moving in a direction that is not parallel to the second traction segment 3212 moving in a direction that is not parallel to each other. Furthermore, the extension direction of the first traction segment 3211 is approximately parallel to the movement direction of the sliding member 39. This also serves to change the extension direction of the traction member 321. Specifically, the angle between the first traction section 3211 and the second traction section 3212 (i.e., between the direction of movement of the first traction section 3211 and the direction of movement of the second traction section 3212) is greater than 90 degrees and less than 270 degrees. More specifically, the angle between the two is approximately 180 degrees.

[0096] Of course, in other embodiments, such as Figure 17 and Figure 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 being provided on the extension line of the sliding groove 96 means that the extension line of the sliding groove 96 is approximately tangent to the outer periphery of the indicator 31.

[0097] According to the seat position display device 3 provided in some embodiments of this application, the sliding member 39 is slidable by the movement of the seat assembly 1 relative to the base 9. 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 and less restricted by the space of the base 9. At the same time, it is more convenient to view the displayed indicator area 3111 during the adjustment of the angle of the seat assembly 1.

[0098] It should be noted that, in one or more of the above embodiments, the seat position display device 3 can also be used to display the sliding position of the seat assembly 1 relative to the base 9 in the horizontal direction. Figure 19 and Figure 20 The illustration shows a seat position display device for a child vehicle according to some other embodiments of this application. The child vehicle can be, for example... Figure 1 and Figure 2 The child vehicle 100 shown includes a base 9 and a seat assembly 1. A horizontal guide rail (not shown) 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 disposed on the base, a slider 39 disposed on the seat assembly, and a drive connection assembly 32 connecting the indicator 31 and the slider 39. The indicator 31 is connected to the slider 39 via the drive connection assembly 32. When the slider 39 slides relative to the sliding groove 96 of the base 9, it causes the indicator 31 to slide relative to the base 9, thereby changing the indicator area 3111 displayed at the viewing window 35. The indicator 31 is generally elongated, its extension direction is generally parallel to the extension direction of the sliding groove 96, and it has multiple indicator areas 3111. The slider 39 has a sliding range along the sliding groove 96 in the front-rear direction D1. (Refer to...) Figure 19 As shown, when the child vehicle is in position "1", the seat assembly is at its rearmost position in the fore-and-aft direction D1 of the sliding range (i.e., the slider 39 is in the first position). (Refer to...) Figure 20 As shown, when the child vehicle is in position "8", the seat assembly is at its foremost position in the fore-and-aft direction D1 of the sliding range (i.e., the slider 39 is in the second position). (Refer to...) Figure 20 It is understood that the base 9 needs to provide a space twice the length of the sliding groove 96 in the front-to-back direction D1 to accommodate the seat position display device, while requiring less space in the left-to-right direction. In this application, the direction facing the child when seated in the seat assembly is defined as the forward direction, and the direction facing away from the child when seated in the seat assembly is defined as the rearward direction. The front end refers to the portion near the front of the base 9 in the front-to-back direction, and the rear end refers to the portion near the rear of the base 9 in the front-to-back direction.

[0099] The seat position display device according to the present invention allows for real-time observation of whether the seat position is properly adjusted during seat position adjustment, and the seat position display device has a simple structure.

[0100] According to the seat position display device and child carrier having the seat position display device provided in this embodiment, the movement of the seat assembly relative to the base drives the movement of the drive connecting assembly, thereby driving the indicator to rotate to change the display area, thus synchronously showing the angle between the backrest of the seat assembly and the base. By rotating the indicator mounted on the base, the space occupied by the indicator can be reduced, the requirements for the indicator's placement position can be lowered, and the space restriction of the base's receiving cavity on the indicator can be reduced. This allows the indicator to be placed in a more easily observable position on the base according to actual needs.

[0101] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0102] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
