[0002] A child safety carrier comprises a base and a carrier body. The base comprises a pull rod and a locking hook, and the carrier body comprises a carrier and a locking rod. The pull rod drives the locking hook to rotate and disengage the locking hook from the locking rod, thereby achieving detachment of the carrier body from the base. However, due to its inherent structural design, the pull rod in the related art cannot smoothly release the locking hook, causing inconvenience to the user. Utility Model Content

[0003] The embodiment of the present application provides a child safety vehicle that can solve the problem in the related art that due to the structural design of the pull rod itself, the pull rod cannot drive the lock hook to release the lock smoothly, causing inconvenience to the user.

[0004] The embodiment of the present application provides a child safety carrier; the child safety carrier can be detachably installed on a car seat, and includes a base and a carrier body, the base includes a shell, a release member and a lock hook, the shell has a accommodating cavity and a first opening connected to the accommodating cavity, the release member is located in the accommodating cavity and movably connected to the shell, the release member has an avoidance portion, the lock hook is arranged corresponding to the first opening and partially passes through the first opening and extends out of the accommodating cavity, the carrier body includes a carrier and a card rod, the carrier is used to carry the child, the card rod is installed at the bottom of the carrier, the lock hook has a locked state and a released state, in the locked state, the lock hook is hooked on the card rod to position the carrier to the shell, in the released state, the lock hook is disengaged from the card rod to unlock the carrier from the shell, the release member is configured to drive the lock hook to rotate by moving relative to the shell, so that the lock hook switches from the locked state to the released state, and the avoidance portion is configured to avoid the tail end of the lock hook during the process of switching the lock hook from the locked state to the released state.

[0005] Based on the child safety vehicle of the embodiment of the present application, an avoidance portion is designed on the release member. When the lock hook switches from the locked state to the released state, the tail end of the lock hook can pass through the avoidance portion. At this time, the release member will not interfere with the tail end of the lock hook, so that the lock hook can be rotated to a suitable angle, thereby disengaging the lock hook from the locking rod, thereby ensuring smooth release of the lock hook and convenient for user use.

[0006] In some embodiments, the avoidance portion includes a notch provided on a side of the release member facing the lock hook.

[0007] Based on the above embodiment, when the lock hook switches from the locked state to the released state, a notch groove can be provided at the tail end of the lock hook, and the release member will not interfere with the tail end of the lock hook, so that the lock hook can be rotated to a suitable angle, thereby disengaging the lock hook from the latch rod to ensure that the lock hook is released smoothly and is convenient for users to use.

[0008] In some embodiments, the depth of the notch groove is greater than or equal to 0.8 mm and less than or equal to 2.0 mm.

[0009] Based on the above embodiment, by reasonably designing the depth of the notch groove, it can be ensured that the release member does not interfere with the tail end of the lock hook, so that the lock hook can be rotated to a suitable angle, thereby disengaging the lock hook from the latch rod, and the structural strength of the release member at the position corresponding to the notch groove can be ensured, so that the release member can provide sufficient supporting strength for the tail end of the lock hook when the lock hook is in a locked state.

[0010] In some embodiments, the base further includes a bracket and an elastic member; the bracket is positioned within the accommodating cavity and fixedly connected to the housing; the locking hook is rotatably connected to the bracket via a rotating shaft; and the elastic member is sleeved around the rotating shaft. When the locking hook is in a locked state, the tail end of the locking hook abuts the release member, and the elastic member undergoes elastic deformation in a direction about the rotation axis of the rotating shaft; when the locking hook is in a released state, the tail end of the locking hook abuts the avoidance portion, and the elastic member is in a naturally extended state.

[0011] Based on the above embodiment, when the lock hook is in the locked state, the tail end of the lock hook abuts the release member to restrict the lock hook from rotating. This allows the lock hook to stably hook onto the latch rod under the elastic force corresponding to the elastic deformation of the elastic member in the rotational direction about the rotation axis, thereby ensuring the stability of the carrier positioned on the housing. When the lock hook switches from the locked state to the released state, the release member moves relative to the housing so that the tail end of the lock hook passes through the escape portion. At this time, the release member does not interfere with the tail end of the lock hook, and the lock hook rotates under the elastic restoring force corresponding to the elastic deformation of the elastic member in the rotational direction about the rotation axis. When the lock hook is in the released state, the lock hook rotates to an appropriate angle so that the tail end of the lock hook abuts the escape portion. At this time, the lock hook is disengaged from the latch rod, and the elastic member is in a naturally extended state, thereby achieving detachment between the carrier and the housing.

[0012] In some embodiments, the housing has a lower inner wall facing away from the vehicle seat; the base further includes a mounting seat, an ISOFIX telescopic tube, an adjustment member, and a locking rod; the mounting seat is disposed on the lower inner wall of the housing; the ISOFIX telescopic tube is slidably connected to the housing and has a plurality of locking holes; the adjustment member is at least partially located within the housing cavity and is movably connected to the housing; the locking rod is disposed on the mounting seat and movably connected to the adjustment member. The locking rod has a locked state and an unlocked state; in the locked state, the locking rod engages with one of the locking holes to position the ISOFIX telescopic tube in the housing; in the unlocked state, the locking rod disengages from all locking holes to unlock the ISOFIX telescopic tube from the housing; the adjustment member is configured to drive the locking rod to move by moving relative to the housing, thereby switching the locking rod from the locked state to the unlocked state.

[0013] Based on the above embodiment, when the housing needs to be fixed to the car seat, the user applies force to the adjustment member, causing the adjustment member to move relative to the housing under the action of the force, thereby driving the locking rod to move, disengaging the locking rod from all locking holes of all ISOFIX extension tubes. The ISOFIX extension tubes are then slid relative to the housing to the appropriate position. The locking rod engages with one of the locking holes of the ISOFIX extension tubes to achieve relative fixation between the ISOFIX extension tubes and the housing. The ISOFIX extension tubes are then engaged with the fixing rod of the car seat to achieve relative fixation between the housing and the car seat. By designing the ISOFIX extension tubes to slide relative to the housing, the ISOFIX extension tubes can be retracted to their minimum length, thereby reducing the packaging material of the child safety carrier and the space occupied by the child safety carrier when it is not in use.

[0014] In some embodiments, the base further includes a support member; the support member is disposed on the lower inner wall surface of the shell and adjacent to the mounting seat, and one end of the support member facing away from the lower inner wall surface of the shell abuts against the bracket.

[0015] Based on the above embodiment, by designing the support member, the support member abuts against the bracket to effectively prevent the shell from deforming, so that the inner bottom surface of the mounting seat will not press against the locking rod, and the locking rod can perform telescopic movement normally, thereby ensuring the telescopic stability and smoothness of the ISOFIX telescopic rod.

[0016] In some embodiments, the support member includes a support rib fixedly connected to the lower inner wall surface of the shell, one end of the support rib facing away from the lower inner wall surface of the shell abuts against the bracket, and the side end of the support rib extends to connect with the outer edge of the mounting seat.

[0017] Based on the above embodiment, the support ribs are designed to abut against the bracket to effectively prevent deformation of the housing, preventing the inner bottom surface of the mounting base from pressing against the locking rod, allowing the locking rod to extend and retract normally, thereby ensuring the stability and smoothness of the ISOFIX telescopic rod. By extending the side ends of the support ribs to connect with the outer edges of the mounting base, the support ribs act as reinforcing ribs, enhancing the structural strength of the mounting base and ensuring that the mounting base provides effective limiting support for the locking rod.

[0018] In some embodiments, the housing further comprises a second opening communicating with its accommodating cavity, and a mating portion is provided on an inner wall surface of the housing. The base further comprises an indicator member, comprising an indicator body and a limiting portion. The indicator body is located within the accommodating cavity of the housing and is rotatably connected to the housing. The limiting portion is provided on the indicator body and engages with the mating portion to limit the rotation angle of the indicator body. The release member is further configured to drive the indicator body to rotate by moving relative to the housing, such that the indicator body rotates until the first indicating portion of the indicator body is aligned with the second opening when the lock hook is in the locked state, and rotates until the second indicating portion of the indicator body is aligned with the second opening when the lock hook is in the released state.

[0019] Based on the above embodiment, when the lock hook is in the locked state, the indicator body should rotate until the first indicator portion is aligned with the second opening. The user can judge whether the lock hook is locked in place with the card rod based on the indicator portion exposed by the indicator body at the second opening, thereby ensuring the safety of children using the child safety carrier.

[0020] In some embodiments, the mating portion includes an arcuate groove provided on the inner wall surface of the shell, with the arcuate groove having the rotation axis of the indicating body as its center; the limiting portion includes a limiting protrusion provided on the indicating body, and the limiting protrusion is inserted into the arcuate groove.

[0021] Based on the above embodiment, the limiting protrusion cooperates with the arc-shaped groove to effectively limit the rotation of the indicating body, which has a simple structure and is easy to implement.

[0022] In some embodiments, the depth of the arcuate groove is greater than or equal to 2.5 mm and less than or equal to 3.0 mm. And / or, the housing has an upper inner wall facing the car seat, the upper inner wall of the housing having a first pivot hole; the indicator further includes a first pivot protrusion connected to a side of the indicator body facing the upper inner wall of the housing, the first pivot protrusion inserted into the first pivot hole, and a height of the first pivot protrusion greater than or equal to 5 mm and less than or equal to 8 mm. And / or, the housing has a lower inner wall facing away from the car seat, the lower inner wall of the housing having a second pivot hole; the indicator further includes a second pivot protrusion connected to a side of the indicator body facing the lower inner wall of the housing, the second pivot protrusion inserted into the second pivot hole, and a height of the second pivot protrusion greater than or equal to 5 mm and less than or equal to 8 mm.

[0023] Based on the above embodiments, by properly designing the depth of the arcuate groove, the risk of the arcuate groove's depth being reduced due to deformation after injection molding of the housing, resulting in its inability to adapt to the height of the stopper protrusion, which could result in the stopper protrusion disengaging from the arcuate groove during the rotation of the indicator body. This could cause the indicator member to fail to accurately indicate the current state of the lock hook, leading to user misjudgment and potentially creating a safety hazard. Furthermore, by properly designing the height of the first pivot protrusion so that it does not disengage from the first pivot hole, the stability and reliability of the indicator body during rotation can be ensured, thereby ensuring the proper indication function of the indicator member. Furthermore, by properly designing the height of the second pivot protrusion so that it does not disengage from the second pivot hole, the stability and reliability of the indicator body during rotation can be ensured, thereby ensuring the proper indication function of the indicator member.

[0044] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0045] Please refer to Figures 1-9 As shown, the present application proposes a child safety vehicle 1, which designs an avoidance portion 22a on the release member 22. The avoidance portion 22a can allow the lock hook 23 to smoothly disengage from the latch rod, thereby ensuring that the lock hook 23 is released smoothly and is convenient for users to use.

[0046] This child safety carrier 1 is removably mounted on a car seat and comprises a base 20 and a carrier body 10. The base 20 comprises a housing 21, a release member 22, and a locking hook 23. The housing 21 has a receiving cavity 21a and a first opening 21b communicating with the receiving cavity 21a. The release member 22 is positioned within the receiving cavity 21a and movably connected to the housing 21. The release member 22 has a relief portion 22a. The locking hook 23 is positioned corresponding to the first opening 21b and partially extends through the first opening 21b to extend outside the receiving cavity 21a. The carrier body 10 comprises a carrier 11 and a latching rod. The carrier 11 is used to support a child. The latching rod is mounted at the bottom of the carrier 11. The lock hook 23 has a locked state and a released state; in the locked state, the lock hook 23 is hooked on the card rod to position the carrier 11 in the shell 21; in the released state, the lock hook 23 is disengaged from the card rod to unlock the carrier 11 from the shell 21; the release member 22 is configured to drive the lock hook 23 to rotate by moving relative to the shell 21, so that the lock hook 23 switches from the locked state to the released state; the avoidance portion 22a is configured to avoid the tail end of the lock hook 23 during the process of switching the lock hook 23 from the locked state to the released state.

[0047] The following combination Figures 1-18 The specific structure of the child safety vehicle 1 is introduced in detail.

[0048] like Figure 1-Figure 2 As shown, the child safety vehicle 1 is detachably mounted on a car seat and includes a vehicle body 10 and a base 20 .

[0049] The carrier body 10 is a supporting structure of the child safety carrier 1 and is used to support a child. The carrier body 10 includes a carrier 11 and a clamping rod (not shown).

[0050] The carrier 11 is a supporting member of the carrier body 10 for supporting a child. The carrier 11 may be, but is not limited to, a cradle or a seat.

[0051] The latching rod serves as a connector for the carrier body 10, cooperating with the locking hook 23 (described below) to secure the carrier 11 relative to the housing 21 (described below). The latching rod is mounted on the bottom of the carrier 11. The specific connection method between the latching rod and the carrier 11 is not specified here, and designers can design it based on actual needs. For example, the latching rod can be removably connected to the carrier 11 through at least one of screwing, snapping, or plugging. In another example, the latching rod can be permanently connected to the carrier 11 through gluing, riveting, welding, injection molding, or 3D printing.

[0052] like Figures 1-9 As shown, the base 20 serves as a support for the child safety vehicle 1 , and is used to carry and fix the vehicle body 10 . The base 20 includes a housing 21 , a locking hook 23 , and a release member 22 .

[0053] The housing 21 serves as the outer shell of the base 20. The specific structure of the housing 21 is not limited herein, and designers may reasonably design it according to actual needs. For example, the housing 21 includes an upper housing 211 and a lower housing 212. The upper housing 211 may be detachably connected to the lower housing 212 by at least one of screw connection, snap connection, or plug connection, but is not limited to the above.

[0054] The housing 21 has a receiving cavity 21a and a first opening 21b communicating with the receiving cavity 21a. For example, when the housing 21 includes an upper shell 211 and a lower shell 212, the upper shell 211 and the lower shell 212 enclose the receiving cavity 21a, and the upper shell 211 is formed with the first opening 21b.

[0055] The locking hook 23 serves as a locking member of the base 20 and is used to cooperate with the clamping rod to achieve relative fixation between the housing 21 and the carrier 11 .

[0056] The locking hook 23 is disposed corresponding to the first opening 21 b of the housing 21 , and a portion of the locking hook 23 passes through the first opening 21 b of the housing 21 and extends out of the accommodating cavity 21 a of the housing 21 .

[0057] The lock hook 23 has a locked state and a released state; when the lock hook 23 is in the locked state, the lock hook 23 is hooked on the card rod to position the carrier 11 in the shell 21, and the relative fixation of the position between the carrier 11 and the shell 21 can be achieved; when the lock hook 23 is in the released state, the lock hook 23 is disengaged from the card rod to unlock the carrier 11 from the shell 21, and the relative change of the position between the carrier 11 and the shell 21 can be achieved (that is, the carrier 11 can be removed from the shell 21).

[0058] The release member 22 serves as a release element of the base 20 and is configured to cooperate with the lock hook 23 to rotate the lock hook 23, thereby switching the lock hook 23 from the locked state to the released state. The specific form of the release member 22 is not limited here, and designers can reasonably design it according to actual needs. For example, the release member 22 can include, but is not limited to, a release lever, a release button, or a release knob.

[0059] The release member 22 is located within the accommodating cavity 21a of the housing 21 and is movably connected to the housing 21. The specific method of movably connecting the release member 22 and the housing 21 is not limited herein, and designers may design the release member 22 appropriately based on actual needs. For example, the release member 22 may be slidably connected to the housing 21, or may be rotationally connected to the housing 21.

[0060] The release member 22 is configured to rotate the lock hook 23 by moving relative to the housing 21, thereby switching the lock hook 23 from the locked state to the released state. For example, when the release member 22 includes a release lever, the release lever is configured to rotate the lock hook 23 by sliding relative to the housing 21, thereby switching the lock hook 23 from the locked state to the released state. For another example, when the release member 22 includes a release button, the release button is configured to rotate the lock hook 23 by sliding relative to the housing 21, thereby switching the lock hook 23 from the locked state to the released state. For another example, when the release member 22 includes a release knob, the release knob is configured to rotate the lock hook 23 by rotating relative to the housing 21, thereby switching the lock hook 23 from the locked state to the released state.

[0061] It is understandable that during the process of the lock hook 23 switching from the locked state to the unlocked state, there is a situation where the lock releasing member 22 does not move to its full position and interferes with the tail end of the lock hook 23 (that is, the lock releasing member 22 blocks the movement trajectory of the tail end of the lock hook 23). At this time, the lock hook 23 cannot be separated from the clamping rod, resulting in the lock hook 23 not being released smoothly. Therefore, in order to ensure the lock hook 23 is released smoothly, Figure 4-Figure 9 As shown, the release member 22 is provided with a clearance portion 22a. The clearance portion 22a is configured to clear the rear end of the hook 23 during the process of switching from the locked state to the released state. Thus, during the process of switching from the locked state to the released state, the rear end of the hook 23 can pass through the clearance portion 22a. At this time, the release member 22 does not interfere with the rear end of the hook 23, allowing the hook 23 to rotate to a suitable angle, thereby disengaging the hook 23 from the latching rod.

[0062] Based on the child safety vehicle 1 in the embodiment of the present application, by designing an avoidance portion 22a on the release member 22, the tail end of the lock hook 23 can pass through the avoidance portion 22a during the process of switching the lock hook 23 from the locked state to the released state. At this time, the release member 22 will not interfere with the tail end of the lock hook 23, allowing the lock hook 23 to rotate to a suitable angle, thereby disengaging the lock hook 23 from the locking rod, thereby ensuring that the lock hook 23 is released smoothly and convenient for users to use.

[0063] like Figure 4-Figure 9 As shown, the relief portion 22a comprises a notch provided on the side of the release member 22 facing the hook 23. In this case, the relief portion 22a comprises a notch (a virtual structure) extending inwardly from the outer wall of the release member 22 facing the hook 23. Thus, during the process of switching the hook 23 from the locked state to the released state, the tail end of the hook 23 can pass through the notch, and the release member 22 will not interfere with the tail end of the hook 23, allowing the hook 23 to rotate to a suitable angle, thereby disengaging the hook 23 from the latch rod, ensuring smooth release of the hook 23 and convenient user operation.

[0064] Specifically, the depth of the notch is greater than or equal to 0.8 mm and less than or equal to 2.0 mm. For example, the depth of the notch can be, but is not limited to, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2.0 mm. Preferably, the depth of the notch is 1.0 mm. By properly designing the depth of the notch, it is possible to ensure that the release member 22 does not interfere with the tail end of the lock hook 23, allowing the lock hook 23 to rotate to a suitable angle to disengage the lock rod. It also ensures the structural strength of the release member 22 at the position corresponding to the notch, so that the release member 22 can provide sufficient support strength for the tail end of the lock hook 23 when the lock hook 23 is in the locked state.

[0065] like Figure 3 、 Figure 6-Figure 9 As shown, the base 20 further includes a bracket 24 and an elastic member (not shown). The bracket 24 is located within the accommodating cavity 21a and is fixedly connected to the housing 21. The locking hook 23 is rotatably connected to the bracket 24 via a rotating shaft. The elastic member is sleeved around the rotating shaft. When the locking hook 23 is in the locked state, the tail end of the locking hook 23 abuts the unlocking member 22, and the elastic member undergoes elastic deformation in the direction of the rotation axis of the rotating shaft. When the locking hook 23 is in the released state, the tail end of the locking hook 23 abuts the avoidance portion 22a, and the elastic member is in a naturally extended state.

[0066] Among them, the bracket 24 serves as the frame of the base 20, and is used to carry components such as the lock hook 23; the specific fixed connection method between the bracket 24 and the shell 21 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the bracket 24 can be but is not limited to being detachably fixedly connected to the shell 21 by at least one of screwing, snapping or plugging; for another example, the bracket 24 can also be but is not limited to being non-detachably fixedly connected to the shell 21 by riveting.

[0067] Elastic members are suitable for elastic deformation when subjected to force and for automatically recovering the elastic deformation after the force is removed. The specific form of the elastic member is not limited here, and designers can reasonably design it according to actual needs. For example, the elastic member can be, but is not limited to, a torsion spring or a coil spring.

[0068] When the lock hook 23 is in the locked state, the tail end of the lock hook 23 abuts the release member 22, restricting the rotation of the lock hook 23. This allows the lock hook 23 to be stably hooked on the latch rod under the elastic force corresponding to the elastic deformation of the elastic member in the rotational direction about the rotation axis, thereby ensuring the stability of the carrier 11 positioned on the housing 21. When the lock hook 23 switches from the locked state to the released state, the release member 22 moves relative to the housing 21 so that the tail end of the lock hook 23 passes through the escape portion 22a. At this time, the release member 22 does not interfere with the tail end of the lock hook 23, and the lock hook 23 rotates under the elastic restoring force corresponding to the elastic deformation of the elastic member in the rotational direction about the rotation axis. When the lock hook 23 is in the released state, the lock hook 23 rotates to an appropriate angle so that the tail end of the lock hook 23 abuts the escape portion 22a. At this point, the lock hook 23 disengages from the latch rod, and the elastic member is in a naturally extended state, allowing the carrier 11 to be disassembled from the housing 21.

[0069] It should be noted that when the user needs to reinstall the disassembled carrier 11 on the shell 21, the user only needs to place the carrier 11 on the shell 21 and let the card rod fall into the lock mouth of the lock hook 23. The gravity of the carrier 11 is transmitted to the lock hook 23 through the card rod. The lock hook 23 rotates under the action of the gravity of the carrier 11. At the same time, the elastic part begins to produce elastic deformation in the direction of the rotation axis around the rotating shaft until the lock hook 23 rotates so that the tail end of the lock hook 23 is re-contacted with the release member 22. At this time, the lock hook 23 is in a locked state again. Of course, the base 20 also includes a first spring (not shown in the figure), which is suitable for generating elastic deformation along the movement direction of the release member 22; when the lock hook 23 is in the locked state, the first spring can be in a natural extension state; when the lock hook 23 is in the released state, the first spring is in a compressed state, so that when the lock hook 23 rotates under the action of the gravity of the carrier 11 so that the tail end of the lock hook 23 is re-contacted with the release member 22, the release member 22 can be automatically reset under the action of the elastic restoring force of the first spring, which is conducive to the release member 22 and the tail end of the lock hook 23 being re-contacted.

[0070] like Figure 3 、 Figure 10-12As shown, the shell 21 has a lower inner wall surface 21c facing away from the car seat; the base 20 also includes a mounting seat 25, an ISOFIX telescopic tube 26, an adjustment member 27 and a locking rod 28; the mounting seat 25 is arranged on the lower inner wall surface 21c of the shell 21; the ISOFIX telescopic tube 26 is slidably connected to the shell 21, and the ISOFIX telescopic tube 26 has a plurality of locking holes 26a; the adjustment member 27 is at least partially located in the accommodating cavity 21a of the shell 21 and is movably connected to the shell 21; the locking rod 28 is arranged on the mounting seat 25 and is movably connected to the adjustment member 27. The locking rod 28 has a locked state and an unlocked state; in the locked state, the locking rod 28 is plugged into one of its locking holes 26 a to position the ISOFIX telescopic tube 26 on the housing 21; in the unlocked state, the locking rod 28 is disengaged from all the locking holes 26 a to unlock the ISOFIX telescopic tube 26 from the housing 21; the adjusting member 27 is configured to drive the locking rod 28 to move by moving relative to the housing 21, so that the locking rod 28 switches from the locked state to the unlocked state.

[0071] The mounting base 25 is used to position the locking rod 28, allowing the locking rod 28 to telescope in a predetermined direction. The specific connection method between the mounting base 25 and the housing 21 is not limited here, and designers can reasonably design it according to actual needs. For example, the mounting base 25 can be, but is not limited to, a removable fixed connection to the housing 21 through at least one of a screw connection, a snap connection, or a plug-in connection. For another example, the mounting base 25 can also be, but is not limited to, a non-removable fixed connection to the housing 21 through gluing, riveting, injection molding, or 3D printing.

[0072] The ISOFIX expansion tube 26 is designed to engage with the positioning rod of the car seat to achieve relative fixation between the housing 21 and the car seat. The specific structure of the ISOFIX expansion tube 26 is not limited here, and designers can reasonably design it according to actual needs. Multiple locking holes 26a are arranged at intervals along the extension direction of the ISOFIX expansion tube 26.

[0073] The locking rod 28 serves as another locking member of the base 20 and is used to cooperate with the locking hole 26 a of the ISOFIX telescopic tube 26 to achieve relative fixation of the position between the ISOFIX telescopic tube 26 and the housing 21 .

[0074] The locking rod 28 is embedded in the mounting base 25 and can move telescopically relative to the mounting base 25 along a predetermined direction.

[0075] The locking rod 28 has a locked state and an unlocked state. When the locking rod 28 is in the locked state, the locking rod 28 is engaged with one of the locking holes 26 a of the ISOFIX expansion tube 26 to position the ISOFIX expansion tube 26 on the housing 21. At this time, the relative position between the ISOFIX expansion tube 26 and the housing 21 can be fixed. When the locking rod 28 is in the unlocked state, the locking rod 28 is disengaged from all the locking holes 26 a of the ISOFIX expansion tube 26 to unlock the ISOFIX expansion tube 26 from the housing 21. At this time, the ISOFIX expansion tube 26 can perform telescopic movement relative to the housing 21, so that the length of the ISOFIX expansion tube 26 exposed outside the accommodating cavity 21 a of the housing 21 can be adjusted.

[0076] Adjustment member 27 serves as another locking / release member of base 20, cooperating with lock rod 28 to cause lock rod 28 to retract, thereby switching lock rod 28 from a locked state to an unlocked state. The specific form of adjustment member 27 is not limited here; designers can design it based on actual needs. For example, adjustment member 27 may include, but is not limited to, an adjustment lever, an adjustment button, or an adjustment knob.

[0077] The adjusting member 27 is movably connected to the housing 21. The specific movably connected manner between the adjusting member 27 and the housing 21 is not limited here, and designers can reasonably design it according to actual needs; for example, the adjusting member 27 can be slidably connected to the housing 21, or the adjusting member 27 can be rotatably connected to the housing 21.

[0078] The adjusting member 27 is configured to drive the lock rod 28 to move by moving relative to the housing 21, so as to switch the lock rod 28 from the locked state to the unlocked state. For example, when the adjusting member 27 includes an adjusting pull rod, the adjusting pull rod is configured to drive the lock rod 28 to retract by sliding relative to the housing 21, so as to switch the lock rod 28 from the locked state to the unlocked state. For another example, when the adjusting member 27 includes an adjusting button, the adjusting button is configured to drive the lock rod 28 to retract by sliding relative to the housing 21, so as to switch the lock rod 28 from the locked state to the unlocked state. For another example, when the adjusting member 27 includes an adjusting knob, the adjusting knob is configured to drive the lock rod 28 to retract by rotating relative to the housing 21, so as to switch the lock rod 28 from the locked state to the unlocked state.

[0079] When the housing 21 needs to be secured to the car seat, the user applies force to the adjusting member 27, causing the adjusting member 27 to move relative to the housing 21 under the action of the force, thereby driving the locking rod 28 to move, disengaging the locking rod 28 from all locking holes 26a of all ISOFIX telescopic tubes 26. The ISOFIX telescopic tubes 26 are then slid to the appropriate position relative to the housing 21. The locking rod 28 engages with one of the locking holes 26a of the ISOFIX telescopic tubes 26 to achieve relative fixation between the ISOFIX telescopic tubes 26 and the housing 21. The ISOFIX telescopic tubes 26 are then engaged with the fixing rod of the car seat to achieve relative fixation between the housing 21 and the car seat. By designing the ISOFIX telescopic tubes 26 to slide relative to the housing 21, the ISOFIX telescopic tubes 26 can be retracted to their minimum length, thereby reducing the packaging material of the child safety carrier 1 and the space occupied by the child safety carrier 1 when it is not in use.

[0080] It should be noted that the base 20 also includes a second spring (not shown in the figure), which is suitable for generating elastic deformation along the movement direction of the locking rod 28; when the locking rod 28 is in the locked state, the second spring can be in a natural extension state or in a compressed state; when the locking rod 28 is in the unlocked state, the second spring is in a compressed state (and the compressive elastic deformation of the second spring when the locking rod 28 is in the unlocked state is greater than the compressive elastic deformation of the second spring when the locking rod 28 is in the locked state), so that the locking rod 28 can be automatically reset to be plugged into one of the locking holes 26a of the ISOFIX telescopic tube 26 under the action of the elastic restoring force of the second spring.

[0081] like Figure 3 、 Figure 10-12 As shown, the base 20 also includes a support member 29; the support member 29 is arranged on the lower inner wall surface 21c of the shell 21 and is arranged adjacent to the mounting seat 25, and the end of the support member 29 facing away from the lower inner wall surface 21c of the shell 21 abuts against the bracket 24. Among them, the support member 29 can be, but is not limited to, a support rib, a support block or a support rod. The specific connection method between the support member 29 and the shell 21 is not limited here, and the designer can make a reasonable design according to actual needs; for example, the support member 29 can be, but is not limited to, a detachable connection with the shell 21 by at least one of screw connection, clip connection or plug connection; for another example, the support member 29 can also be, but is not limited to, a non-detachable connection with the shell 21 by riveting, gluing, injection molding or 3D printing.

[0082] It is understood that the child safety vehicle 1 further includes a support foot 40 connected to the housing 21. Before the support member 29 is designed, when the support foot 40 contacts the vehicle floor, it pushes upward against the housing 21 (specifically, the lower housing 212 described above). This causes the housing 21 to deform, causing the inner bottom surface of the mounting seat 25 to press against the locking rod 28, preventing the locking rod 28 from extending or retracting. After the support member 29 is designed, the support foot 40 still pushes upward against the housing 21 (specifically, the lower housing 212 described above) when contacting the vehicle floor. However, due to the presence of the support member 29, the support member 29 abuts against the bracket 24, effectively preventing deformation of the housing 21. This prevents the inner bottom surface of the mounting seat 25 from pressing against the locking rod 28, allowing the locking rod 28 to extend or retract normally, thereby ensuring the stability and smoothness of the ISOFIX telescopic rod.

[0083] Specifically, if Figure 3 、 Figure 10-12 As shown, the support member 29 includes a support rib fixedly connected to the lower inner wall surface 21c of the shell 21, and the end of the support rib facing away from the lower inner wall surface 21c of the shell 21 abuts the bracket 24, and the side end of the support rib extends to connect with the outer edge of the mounting seat 25. The support rib can be, but is not limited to, forming an integrated structure with the shell 21 and the mounting seat 25 by injection molding or 3D printing. By designing the support rib, the support rib abuts against the bracket 24 to effectively prevent the shell 21 from deforming, so that the inner bottom surface of the mounting seat 25 does not support the locking rod 28, and the locking rod 28 can perform normal telescopic movement, thereby ensuring the telescopic stability and smoothness of the ISOFIX telescopic rod. By designing the side end of the support rib to extend to connect with the outer edge of the mounting seat 25, the support rib is equivalent to a reinforcing rib that can strengthen the structural strength of the mounting seat 25, so that the mounting seat 25 provides effective limiting support for the locking rod 28.

[0084] like Figure 1 、 Figure 13-16 As shown, the housing 21 further has a second opening 21d communicating with its accommodating cavity 21a, and a mating portion 21e is provided on the inner wall of the housing 21. The base 20 further includes an indicator member 31, which includes an indicator body 311 and a limiting portion 312. The indicator body 311 is located within the accommodating cavity 21a of the housing 21 and is rotatably connected to the housing 21. The limiting portion 312 is provided on the indicator body 311 and engages with the mating portion 21e to limit the rotation angle of the indicator body 311. The release member 22 is further configured to rotate the indicator body 311 by moving relative to the housing 21, such that the indicator body 311 rotates until the first indicating portion 311a of the indicator body 311 is aligned with the second opening 21d when the lock hook 23 is in the locked state, and rotates until the second indicating portion 311b of the indicator body 311 is aligned with the second opening 21d when the lock hook 23 is in the released state.

[0085] The mating portion 21e serves as a limiting structure, configured to engage with the limiting portion 312 to limit the rotation angle of the indicator body 311. The specific connection method between the mating portion 21e and the housing 21 is not limited herein, and designers may design it appropriately based on actual needs. For example, the mating portion 21e may be, but is not limited to, integrally formed with the housing 21 via injection molding or 3D printing.

[0086] The indicator 31 is used to indicate whether the lock hook 23 is currently in a locked state or a released state. The user can determine the current state of the lock hook 23 based on the indicator 31 .

[0087] The indicator body 311 serves as the main body of the indicator member 31. The specific structure of the indicator body 311 is not limited here, and designers can reasonably design it according to actual needs. For example, the indicator body 311 can be, but is not limited to, a fan-shaped plate structure or a circular plate structure. The indicator body 311 has a first indicating portion 311a and a second indicating portion 311b. The first indicating portion 311a can be, but is not limited to, a coating of one color (e.g., green) sprayed on the indicator body 311, while the second indicating portion 311b can be, but is not limited to, a coating of another color (e.g., red) sprayed on the indicator body 311.

[0088] The limiting portion 312 serves as a limiting structure for the indicator 31, and is used to engage with the mating portion 21e to limit the rotation angle of the indicator body 311. The specific form of the limiting portion 312 is not limited here, and designers can reasonably design it according to actual needs. For example, the limiting portion 312 can be, but is not limited to, a virtual structure such as an arc-shaped groove formed on the indicator body 311, while the corresponding mating portion 21e can be, but is not limited to, a physical structure such as a limiting protrusion provided on the inner wall surface of the housing 21. For another example, the limiting portion 312 can be, but is not limited to, a physical structure such as a limiting protrusion provided on the indicator body 311, while the corresponding mating portion 21e can be, but is not limited to, a virtual structure such as an arc-shaped groove formed on the inner wall surface of the housing 21. The specific connection method between the limiting portion 312 and the indicator body 311 is not limited here, and designers can reasonably design it according to actual needs. For example, the limiting portion 312 can be, but is not limited to, integrally formed with the indicator body 311 through injection molding or 3D printing.

[0089] When the lock hook 23 is in the locked state, the indicator body 311 should rotate so that the first indicator portion 311a is aligned with the second opening 21d. The user can determine whether the lock hook 23 is properly locked with the card rod based on the indicator portion exposed by the indicator body 311 at the second opening 21d, thereby ensuring the safety of the child when using the child safety vehicle 1. If the user sees the first indicator portion 311a through the second opening 21d, it means that the lock hook 23 is currently in the locked state and is properly locked with the card rod. If the user sees the first indicator portion 311a and the second indicator portion 311b through the second opening 21d, it means that the lock hook 23 is not properly locked with the card rod. If the user sees the second indicator portion 311b through the second opening 21d, it means that the lock hook 23 is currently in the released state and is disengaged from the card rod.

[0090] Specifically, the mating portion 21e comprises an arcuate groove formed on the inner wall of the housing 21, centered about the rotation axis of the indicator body 311. The limiting portion 312 comprises a limiting protrusion formed on the indicator body 311, which is inserted into the arcuate groove. This limiting protrusion and the arcuate groove cooperate to effectively limit the rotation of the indicator body 311, resulting in a simple structure and ease of implementation.

[0091] like Figure 16-18 As shown, other structural designs of the arc groove, the limiting protrusion, and the indicator 31 may include, but are not limited to, one or more of the following embodiments.

[0092] In the first embodiment, the depth of the arcuate groove is greater than or equal to 2.5 mm and less than or equal to 3.0 mm. For example, the depth of the arcuate groove may be, but is not limited to, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3.0 mm. Preferably, the depth of the arcuate groove is 2.7 mm. By properly designing the depth of the arcuate groove, the possibility of the arcuate groove being reduced in depth due to deformation after injection molding of the housing 21 and failing to match the height of the stop protrusion can be effectively reduced. This could result in the stop protrusion disengaging from the arcuate groove during the rotation of the indicator body 311, preventing the indicator 31 from correctly indicating the current state of the lock hook 23, leading to user misjudgment and potential safety hazards.

[0093] In the second embodiment, the housing 21 has an upper inner wall 21f facing the car seat, and the upper inner wall 21f of the housing 21 has a first pivot hole. The indicator member 31 also includes a first pivot protrusion 313, which is connected to the side of the indicator body 311 facing the upper inner wall 21f of the housing 21 and inserted into the first pivot hole. The height of the first pivot protrusion 313 is greater than or equal to 5 mm and less than or equal to 8 mm. The first pivot protrusion 313 can be, but is not limited to, integrally formed with the indicator body 311 through injection molding or 3D printing. For example, the height of the first pivot protrusion 313 can be, but is not limited to, 5 mm, 6 mm, 7 mm, or 8 mm. Preferably, the height of the first pivot protrusion 313 is 6 mm. By properly designing the height of the first pivot protrusion 313, the first pivot protrusion 313 will not fall out of the first pivot hole, ensuring the stability and reliability of the indicator body 311 during rotation, thereby ensuring the effective indicating function of the indicator member 31.

[0094] In a third embodiment, the housing 21 has a lower inner wall 21c facing away from the car seat. The lower inner wall 21c of the housing 21 has a second pivot hole. The indicator member 31 also includes a second pivot protrusion 314 connected to the side of the indicator body 311 facing the lower inner wall 21c of the housing 21. The second pivot protrusion 314 is inserted into the second pivot hole. The height of the second pivot protrusion 314 is greater than or equal to 5 mm and less than or equal to 8 mm. The second pivot protrusion 314 can be, but is not limited to, integrally formed with the indicator body 311 through injection molding or 3D printing. For example, the height of the second pivot protrusion 314 can be, but is not limited to, 5 mm, 6 mm, 7 mm, or 8 mm. Preferably, the height of the second pivot protrusion 314 is 6 mm. By properly designing the height of the second pivot protrusion 314, the second pivot protrusion 314 will not fall out of the second pivot hole, ensuring the stability and reliability of the indicator body 311 during rotation, thereby ensuring the effective indicating function of the indicator member 31.
