Description

Technical Field

[0001] This invention relates to the field of child safety products technology, specifically a car-mounted child carrier. Background Technology

[0002] Car seat carriers are primarily designed for toddlers and consist of a base that attaches to the car seat and a detachable carrier attached to the base. The toddler sits or lies in the carrier, whose enveloping design effectively restrains and protects them. When used in the car, the carrier is stably attached to the base, functioning as a child safety seat. When not in the car, the carrier needs to be unlocked from the base, allowing the toddler to be easily lifted out of the vehicle. It offers versatility and convenience.

[0003] In existing technology, the child carrier is secured to the base by four hooks. When separating the carrier from the base, pulling the lever simultaneously unlocks all four hooks. While this is convenient, it has drawbacks: in the event of a vehicle collision or other dangerous situation, the force of the impact could damage the connection between the carrier and the base. If the lever is accidentally triggered, causing all four hooks to unlock, the carrier could detach from the base, potentially exacerbating the injury to the child inside. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle-mounted child carrier to address the shortcomings of the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a car seat child carrier, comprising a base connected to a car seat and a carrier connected to the base via a detachable connection structure. The detachable connection structure includes two parallel rods fixedly connected to the bottom of the carrier, and two trigger mechanisms disposed on the base, one at the front and one at the rear. Each trigger mechanism corresponds to one of the two rods. Each trigger mechanism includes two trigger units, each trigger unit comprising: a hook, the middle of which is rotatably connected to the base, having a hook portion at its upper end and a insertion hole at its lower end; a first elastic element, the process of which restores its deformation drives the hook portion to engage with the corresponding rod; and an elastic telescopic rod, comprising a sleeve rod and an inner rod that slide in opposite directions, the sleeve rod extending along... The rotation path of the hook is movably connected to the base. A spring is provided between the inner rod and the sleeve rod to allow the inner rod to slide and retract relative to the sleeve rod. During the process of the inner rod sliding and extending against the spring force, it has a insertion position that engages with the socket. A connecting rod is slidably connected to the base in the front-back direction. A stop rod is fixedly connected to the connecting rod. During the sliding of the connecting rod relative to the base, the stop rod can engage with the sleeve rod. A conical body is coaxially connected to the inner rod. A pull rod is movably connected inside the connecting rod. A handle is provided at the front end of the pull rod. The pull rod and the connecting rod can engage with each other. A column rod is connected to the pull rod through a connector. When the pull rod is pulled by the handle, the column rod slides and engages with the conical surface of the conical body, so that the inner rod slides relative to the sleeve rod to the insertion position.

[0006] Furthermore, the rod of the triggering mechanism located on the rear side is a straight rod, and the rod of the triggering mechanism located on the front side includes a connected curved section and a straight rod section. The straight rod section can slide and abut against the corresponding conical body. The pull rod includes a rear section and a front section that are hinged together. The rear section is slidably connected to the connecting rod and is pulled and fixedly connected to the front section. The rod of the triggering mechanism located on the rear side is connected to the rear section, and the rod of the triggering mechanism located on the front side is connected to the front section. During the rotation of the front section relative to the rear section, the corresponding rod has: an arc-shaped section aligned with the avoidance position of the corresponding conical body, and a straight rod section aligned with the abutment position of the corresponding conical body. A second elastic element is provided between the front section and the connecting rod. During the process of the second elastic element restoring its deformation, it drives the rod on the front section to be in the avoidance position.

[0007] Furthermore, the conical body and the corresponding inner rod are coaxially rotatably connected.

[0008] Furthermore, the portion of the column that slides against the corresponding conical body is rotatable.

[0009] Furthermore, the first elastic element is a tension spring, one end of which is connected to the base, and the other end is connected to the position between the rotating shaft of the hook and the hook part.

[0010] Furthermore, the second elastic element is a compression spring, with one end connected to the front section and the other end connected to the connecting rod.

[0011] Furthermore, a blocking part is provided at the front end of the connecting rod, and the front end of the pull rod abuts against the blocking part.

[0012] Furthermore, a telescopic support rod is hinged to the front end of the base.

[0013] Furthermore, the basket is hinged with a handle.

[0014] In the above technical solution, the present invention provides a vehicle-mounted child carrier. During the first half of the process of pulling the pull rod, the column rod and the conical surface of the cone body slide and abut against each other, so that the inner rod slides relative to the sleeve rod into the insertion hole of the corresponding hook, that is, the inner rod moves to the insertion position. During the second half of the process of pulling the pull rod, the pull rod abuts against the connecting rod and drives the connecting rod to move together. The stop bar on the connecting rod abuts against the sleeve rod to pull the sleeve rod. The sleeve rod pulls the hook to rotate through the inner rod, thereby causing the hook head to disengage from the rod body, that is, to realize the separation between the carrier and the base. In this invention, when a vehicle experiences a dangerous collision, the immense impact force acts on the in-car child carrier. Even if the detachable connection structure between the carrier and the base is damaged, because the pull rod is located inside the connecting rod and the connecting rod can move relative to the inner rod, the impact force will preferentially act on the connecting rod compared to the pull rod. This causes the connecting rod to overcome the elastic force of the first elastic element and slide relative to the base. The inner rod is not triggered under the protection of the connecting rod. Therefore, when the stop bar on the connecting rod abuts against the sleeve rod, causing the elastic telescopic rod to move, the inner rod is inserted into the socket, thus preventing the hook from rotating and unlocking the hook from the rod body. This ensures that the carrier remains firmly connected to the base, effectively protecting the child inside the carrier. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-8This invention provides a car-mounted child carrier 2, comprising a base 1 connected to a car seat and a carrier 2 connected to the base 1 via a detachable connection structure. A telescopic support rod 6 is hinged to the front end of the base 1, and a handle 5 is hinged to the carrier 2. The detachable connection structure includes two parallel rods 4 fixedly connected to the bottom of the carrier 2, and two front and rear triggering mechanisms disposed on the base 1. The two triggering mechanisms cooperate one-to-one with the two rods 4. Each triggering mechanism includes two triggering units 3, and each triggering unit 3 includes a hook 3.1, a first elastic element 3.2, an elastic telescopic rod 3.3, and a connecting rod 3.4. The system comprises a cone-shaped body 3.5, a pull rod 3.6, and a column rod 3.8. The hook 3.1 is rotatably connected to the base 1 at its middle. The upper end of the hook 3.1 has a hook portion, and the lower end has an insertion hole 3.11. The first elastic element 3.2, during its recovery process, causes the hook portion to engage with the corresponding rod 4. Specifically, the first elastic element 3.2 is a tension spring, with its front end connected to the base 1 and its rear end connected between the rotating shaft of the hook 3.1 and the hook portion; or, the first elastic element 3.2 is a compression spring, with its front end connected to the base 1 and its rear end connected between the rotating shaft of the hook 3.1 and the insertion hole 3.11. The elastic telescopic rod 3.3 includes a sleeve rod 3.31 and an inner rod 3.32 that are slidably fitted together. The sleeve rod 3.31 is movably connected to the base 1 along the rotation path of the hook 3.1. A spring is provided between the inner rod 3.32 and the sleeve rod 3.31 to allow the inner rod 3.32 to slide and contract relative to the sleeve rod 3.31. During the process of sliding and extending against the spring force, the inner rod 3.32 has a insertion position that engages with the insertion hole 3.11. The connecting rod 3.4 is slidably connected to the base 1 in the front-back direction. A stop rod 3.42 is fixedly connected to the connecting rod 3.4. During the sliding of the connecting rod 3.4 relative to the base 1, the stop rod 3.42 can engage with the sleeve rod 3.31. 31. Abutting fit; the conical body 3.5 is coaxially connected to the inner rod 3.32; the pull rod 3.6 is movably connected inside the connecting rod 3.4, and the front end of the pull rod 3.6 is provided with a handle 3.7. The pull rod 3.6 and the connecting rod 3.4 can abut against each other. Specifically, the front end of the connecting rod 3.4 is provided with a blocking part 3.41, and the front end of the pull rod 3.6 abuts against the blocking part 3.41; the column rod 3.8 is connected to the pull rod 3.6 through the connector 3.9. The process of pulling the pull rod 3.6 by the handle 3.7 causes the column rod 3.8 to slide against the conical surface of the conical body 3.5, so that the inner rod 3.32 slides relative to the sleeve rod 3.31 to the insertion position.

[0026] The present invention provides a vehicle-mounted child carrier 2. By pulling the first half of the lever 3.6 forward, the column 3.8 and the conical surface of the cone 3.5 slide and abut against each other, causing the inner rod 3.32 to slide relative to the sleeve rod 3.31 into the insertion hole 3.11 of the corresponding hook 3.1. That is, the inner rod 3.32 moves to the insertion position. During the second half of the pulling of the lever 3.6, the lever 3.6 abuts against the connecting rod 3.4, causing the connecting rod 3.4 to move together. The stop bar 3.42 on the connecting rod 3.4 abuts against the sleeve rod 3.31 to pull the sleeve rod 3.31. The sleeve rod 3.31 pulls the hook 3.1 to rotate through the inner rod 3.32, thereby causing the hook head to disengage from the rod body 4, thus realizing the separation between the carrier 2 and the base 1. When the basket 2 is installed on the base 1, simply align the rod 4 with the top of the corresponding hook 3.1. The top of the hook 3.1 is an arc or slope that tilts towards the end of the hook. By relying on the weight of the basket 2 and the child, or by pressing down on the basket 2, the rod 4 can slide and abut against the top of the corresponding hook 3.1. Overcoming the elastic force of the first elastic element 3.2, the hook 3.1 is pushed open and moved down to abut against the base 1. At this time, the rod 4 disengages from the top of the hook 3.1, and the elastic force of the first elastic element 3.2 causes the hook 3.1 to reset and engage with the rod 4, thus connecting the basket 2 to the base 1.

[0027] In this embodiment, when a vehicle experiences an accidental collision or other dangerous situation, the enormous impact force acts on the in-vehicle child carrier 2. Even if the detachable connection structure between the carrier 2 and the base 1 is damaged, because the pull rod 3.6 is located inside the connecting rod 3.4, and the connecting rod 3.4 can move relative to the inner rod 3.32, the impact force will preferentially act on the connecting rod 3.4 compared to the pull rod 3.6. This causes the connecting rod 3.4 to overcome the elastic force of the first elastic element 3.2 and slide relative to the base 1. The inner rod 3.32 is not triggered under the protection of the connecting rod 3.4. Therefore, when the stop bar 3.42 on the connecting rod 3.4 abuts against the sleeve rod 3.31 and the elastic telescopic rod 3.3 moves, the inner rod 3.32 is inserted into the insertion hole 3.11, thus preventing the hook 3.1 from rotating and preventing the hook 3.1 from unlocking from the rod body 4. This ensures that the carrier 2 remains firmly connected to the base 1, providing effective protection for the child inside the carrier 2.

[0028] As a preferred embodiment of the above embodiments, in another embodiment of the present invention, the rod 3.8 of the triggering mechanism located on the rear side is a straight rod, and the rod 3.8 of the triggering mechanism located on the front side includes a connected curved section 3.81 and a straight rod section 3.82, the straight rod section 3.82 being able to slide and abut against the corresponding conical body 3.5; the pull rod 3.6 includes a hinged rear section 3.61 and a front section 3.62, the rear section 3.61 being slidably connected to the connecting rod 3.4 and pulled and fixedly connected to the front section 3.62, the rod 3.8 of the triggering mechanism located on the rear side being connected to the rear section 3.61, the triggering mechanism located on the front side... The column rod 3.8 is connected to the front section 3.62. During the rotation of the front section 3.62 relative to the rear section 3.61, the corresponding column rod 3.8 has: an arc-shaped segment aligned with the corresponding cone 3.5 in a clearance position, and a straight rod segment 3.82 aligned with the corresponding cone 3.5 in an abutment position. A second elastic element 3.10 is provided between the front section 3.62 and the connecting rod 3.4. During the recovery deformation process of the second elastic element 3.10, the column rod 3.8 on the front section 3.62 is driven to be in the clearance position. Specifically, the second elastic element 3.10 is a compression spring, one end of which is connected to the front section 3.62 and the other end is connected to the connecting rod 3.4.

[0029] In the previous embodiment, when detaching the basket 2 from the base 1, since the parent's body position is higher than the handle 3.7, pulling the pull rod provides not only a forward pulling force but also an upward component force. Therefore, in this embodiment, when detaching the basket 2 from the base 1, the parent first lifts the pull rod upward, causing the front section 3.62 of the lever 3.6 to overcome the elastic force of the second elastic element 3.10 and rotate relative to the rear section 3.61, thereby causing the column rod 3.8 of the front trigger mechanism to move upward to the contact position. Then, the pull rod 3.6 is pulled forward by the handle 3.7, causing the column rod 3.8 on the rear section 3.61 and the column rod 3.62 on the front section 3.62 to move upward. The straight rod sections 3.82 of rod 3.8 all slide and abut against the conical surfaces of the corresponding conical bodies 3.5, so that each inner rod 3.32 slides relative to the sleeve rod 3.31 into the insertion hole 3.11 of the corresponding hook 3.1. That is, the inner rod 3.32 moves to the insertion position. Continue to pull the handle 3.7, and the pull rod 3.6 abuts against the blocking part 3.41 of the connecting rod 3.4, causing the connecting rod 3.4 to move together. The stop bar 3.42 on the connecting rod 3.4 abuts against the sleeve rod 3.31 to pull the sleeve rod 3.31. The sleeve rod 3.31 pulls the hook 3.1 to rotate through the inner rod 3.32, thereby causing the hook head to disengage from the rod body 4, that is, to achieve the separation between the basket 2 and the base 1. When the basket 2 is installed on the base 1, simply align the rod 4 with the top of the corresponding hook 3.1, press down on the basket 2 to overcome the elastic force of the first elastic element 3.2 so that the rod 4 engages with the hook, thus connecting the basket 2 to the base 1. The elastic force of the second elastic element 3.10 will cause the front section 3.62 to swing down relative to the rear section 3.61, so that the column rod 3.8 on the front section 3.62 remains in the normal state of avoiding the work position.

[0030] In this embodiment, when a vehicle experiences a dangerous situation such as an accidental collision, the enormous impact force acts on the in-vehicle child carrier 2. Even if the detachable connection structure between the carrier 2 and the base 1 is damaged, because the pull rod 3.6 is located inside the connecting rod 3.4, and the connecting rod 3.4 can move relative to the inner rod 3.32, the impact force will preferentially act on the connecting rod 3.4 compared to the pull rod 3.6. This causes the connecting rod 3.4 to overcome the elastic force of the first elastic member 3.2 and slide relative to the base 1. Because lever 3.32 is not triggered under the protection of link 3.4, the stop lever 3.42 on link 3.4 abuts against sleeve lever 3.31, causing the elastic telescopic lever 3.3 to move. This prevents the inner lever 3.32 from being inserted into the insertion hole 3.11, thus preventing the hook 3.1 from rotating and unlocking the lever 4. This ensures the basket 2 remains securely connected to the base 1, providing effective protection for the child inside the basket 2. Furthermore, even if a collision occurs, the force avoids link 3.4 and acts directly... The extremely low probability of the pull rod 3.6 shifting in the front-to-back direction is unlikely to occur in this embodiment, and will not cause the lift to detach from the base 1. This is because when the pull rod 3.6 shifts relative to the connecting rod 3.4, only the column rod 3.8 on the rear section 3.61 of the pull rod 3.6 will slide and abut against the corresponding conical body 3.5, causing the corresponding inner rod 3.32 to slide to the insertion position, thereby driving the corresponding hook 3.1 to rotate and unlock. However, the front section 3.62 of the pull rod 3.6... Since the inner rod 3.32 is in the avoidance position, the curved section 3.81 is aligned with the corresponding cone 3.5. Therefore, when the pull rod 3.6 is displaced, the curved section 3.81 cannot cooperate with the corresponding cone 3.5 to move the inner rod 3.32 to the insertion position. As a result, the inner rod 3.32 will not drive the corresponding hook 3.1 to rotate and unlock, thus ensuring that the trigger mechanism located on the front side remains in the locked state with the corresponding rod 4, thereby preventing the basket 2 from detaching from the base 1 and ensuring the safety of the child.

[0031] As a preferred embodiment of the present invention, the conical body 3.5 and the corresponding inner rod 3.32 are coaxially rotatably connected, and / or the portion of the column rod 3.8 that slides against the corresponding conical body 3.5 is rotatable. For example, the column rod 3.8 of the trigger mechanism located on the rear side is rotatably connected to the connector 3.9, and the straight rod section 3.82 and the bent section 3.81 of the column rod 3.8 of the trigger mechanism located on the front side are rotatably connected. This allows the sliding contact position of the column rod 3.8 and the conical body 3.5 to change as much as possible each time the basket 2 is removed from the base 1, significantly reducing the wear at the contact point between the column rod 3.8 and the conical body 3.5 and improving the service life of the detachable connection structure.

[0032] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
