Description

Technical Field

[0001] The utility model relates to the technical field of child safety seats, and in particular to an ISOFIX mechanism and a child seat. Background Art

[0002] The ISOFIX mechanism is a connection mechanism installed on child safety seats that can be attached to car seats. The ISOFIX mechanism consists of a sleeve and a telescopic rod. The sleeve is fixed inside the child safety seat, and the telescopic rod slides inside the sleeve. The telescopic rod can extend from the sleeve and connect to the car seat.

[0003] In related technology, a sensor is mounted on the telescopic rod and a sensor switch is installed on the outside of the sleeve. The sensor moves synchronously with the telescopic rod. When the sensor moves with the telescopic rod into the sensing range of the sensor switch, a light-emitting unit installed on the child safety seat is illuminated. When illuminated, the light-emitting unit provides illumination, warning, or prompts. However, the thickness of the sleeve can block the sensing signal between the sensor and the sensor switch, preventing the sensor switch from receiving the sensing signal immediately, resulting in a certain lag in the sensor switch's response. Utility Model Content

[0004] In order to solve at least one aspect of the above problems, the present invention provides an ISOFIX mechanism, including an ISOFIX component suitable for being movably connected to a child safety seat body, and also including a circuit board, a sensing control unit and a light-emitting component that are communicatively connected to each other. The ISOFIX component includes a sleeve and a telescopic connecting rod, the sleeve is installed in the child safety seat body, and the telescopic connecting rod is slidably installed in the sleeve, the sensing control unit includes a first sensing component and a second sensing component, the first sensing component is installed on the telescopic connecting rod, and the second sensing component is installed on the sleeve or the child safety seat body, when the telescopic connecting rod moves until the first sensing component and the second sensing component sense each other, the circuit board controls the light-emitting component to light up, and a signal transmission channel is opened on the outer wall of the sleeve to smoothly transmit the sensing signal between the first sensing component and the second sensing component, and the signal transmission channel is connected to the inside of the sleeve.

[0005] Optionally, the first sensing member moves synchronously with the telescopic connecting rod, the second sensing member is mounted on the sleeve, and the signal transmission channel is a circular hole.

[0006] Optionally, the signal transmission channel is an elongated hole, and an extending direction of the signal transmission channel is consistent with a sliding direction of the telescopic connecting rod.

[0007] Optionally, the second induction component is installed on the inner wall of the signal transmission channel.

[0008] Optionally, the first sensing member is installed at the tail end of the telescopic connecting rod.

[0009] Optionally, a mounting lug is provided at the tail end of the telescopic connecting rod, a gap is provided between the circumference of the mounting lug and the inner circumferential wall of the sleeve, and the first sensing element is mounted on the mounting lug.

[0010] Optionally, a mounting groove is formed on a side of the mounting ear close to the signal transmission channel, and the first sensing component is installed in the mounting groove, and the first sensing component does not protrude from the mounting groove.

[0011] Optionally, a side of the signal transmission channel close to the rear end of the sleeve passes through the sleeve, and a side close to the front end of the sleeve does not pass through the sleeve.

[0012] Compared with the prior art, the beneficial technical effects of the present invention are:

[0013] 1. The setting of the signal transmission channel enables the sensing signal emitted by the first sensing element to be transmitted unimpeded, so that the second sensing element can promptly receive the sensing signal emitted by the first sensing element, thereby promptly lighting the light-emitting element.

[0014] 2. The signal transmission channel passes through the sleeve on the side close to the rear end of the sleeve, and the first sensing element is arranged at the rear end of the telescopic connecting rod. When the first sensing element slides out toward the front end of the sleeve along with the telescopic connecting rod, the sensing signal emitted by the first sensing element can always be unimpeded by the thickness of the sleeve wall, thereby improving the sensitivity of the second sensing element during sensing.

[0015] 3. The second sensing element is installed on the hole wall of the signal transmission channel, so that the distance between the second sensing element and the first sensing element is closer, thereby improving the effect of the second sensing element in receiving the sensing signal.

[0016] 4. Since there is a certain gap between the mounting ear and the inner wall of the sleeve, after the first sensing element is installed in the mounting groove on the mounting ear, it is not easy for the first sensing element to interfere with the telescopic connecting rod when sliding synchronously, and it is not easy for the first sensing element to be damaged by friction with the sleeve.

[0017] In addition, the present invention provides a child seat with a lighting function, comprising the ISOFIX mechanism described above.

[0018] Optionally, the child seat further includes a seat body, and the light-emitting element is arranged on the back of the seat body. When the first sensing element and the second sensing element sense each other, the light-emitting element is lit to illuminate the connection between the ISOFIX component and the car seat.

[0019] Compared with the prior art, the child safety seat described in the present invention has the same advantages as those mentioned above over the prior art, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] In the first aspect, the embodiment of the present invention provides an ISOFIX mechanism, referring to Figure 1 and Figure 2 The ISOFIX mechanism includes an ISOFIX component 1, a circuit board (not shown in the figure) that is interconnected for communication, a sensing control unit 2, and a light-emitting element 3. The ISOFIX component 1 is suitable for being movably connected to the child safety seat body to fix the child safety seat body on the car seat. The circuit board is installed in the child safety seat body and is used to transmit the signal emitted by the sensing control unit 2 to the control system to light up or extinguish the light-emitting element 3. The ISOFIX component 1 includes a sleeve 11 and a telescopic connecting rod 12. The sleeve 11 is fixedly installed on the child safety seat body. The telescopic connecting rod 12 is inserted into the sleeve 11 and slides in the sleeve 11. After the telescopic connecting rod 12 extends from the sleeve 11, it can be connected to the car seat. The sensing control unit 2 is partially installed on the telescopic connecting rod 12 and moves synchronously with the telescopic connecting rod 12; it is also partially installed on the sleeve 11. When the telescopic connecting rod 12 moves and causes the sensing control unit 2 to receive a signal, the light-emitting element 3 will be illuminated. A signal transmission channel 111 is provided on the outer wall of the sleeve 11 and communicates with the interior of the sleeve 11 . The signal transmission channel 111 communicates with the interior of the sleeve 11 , thereby making the induction signal of the induction control unit 2 more smoothly transmitted and less susceptible to obstruction.

[0030] It's worth noting that the communication connection described above is a method of communication between connected devices through signal transmission. Communication connections include wired and wireless connections. Wired connections primarily utilize optical cables or optical fibers; wireless connections include wireless signal connections and magnetic induction connections. In another embodiment, the circuit board can be mounted on the outer wall of the casing 11.

[0031] Reference Figure 2 and Figure 3 , wherein the sensing control unit 2 includes a first sensing element 21 and a second sensing element 22, and the first sensing element 21 and the second sensing element 22 are wirelessly connected. The first sensing element 21 is installed on the telescopic connecting rod 12 and slides synchronously with the telescopic connecting rod 12, and the second sensing element 22 is installed on the sleeve 11, so that the distance between the second sensing element 22 and the first sensing element 21 is closer, so that the second sensing element 22 can receive the sensing signal of the first sensing element 21 in time. As the telescopic connecting rod 12 extends, the first sensing element 21 gradually moves toward the direction close to the second sensing element 22. When the distance between the first sensing element 21 and the second sensing element 22 is less than a preset value, the sensing signal between the first sensing element 21 and the second sensing element 22 is connected, and the light-emitting element 3 will be lit through the circuit board. In another embodiment, the second sensing element 22 can be installed on the child safety seat body.

[0032] The first sensing member 21 can be an inductive switch or an inductor that cooperates with the inductive switch. If the first sensing member 21 is an inductive switch, the second sensing member 22 is an inductor; if the first sensing member 21 is an inductor, the second sensing member 22 is an inductive switch. In this embodiment, it is preferred that the first sensing member 21 is an inductor, the second sensing member 22 is an inductive switch, the second sensing member 22 is electrically connected to the circuit board, and the circuit board is electrically connected to the light-emitting member 3. In addition, in this embodiment, it is preferred that the first sensing member 21 is a magnet, and the second sensing member 22 is a magnetic sensitive switch. When the distance between the magnet and the magnetic sensitive switch is less than a preset value when the magnet moves with the telescopic connecting rod 12, the circuit board controls the light-emitting member 3 to light up.

[0033] Reference Figure 2 and Figure 4 One end of the telescopic connecting rod 12 is integrally formed with a mounting lug 121. If the side of the telescopic connecting rod 12 on which the mounting lug 121 is provided is the rear end of the telescopic connecting rod 12, then the other end of the telescopic connecting rod 12 is the front end. When the telescopic connecting rod 12 is extended or retracted, the front end extends out of the sleeve 11. Similarly, if the end of the sleeve 11 near the mounting lug 121 is the rear end of the sleeve 11, then the other end of the sleeve 11 is the front end. The mounting lug 121 is located in the middle of the rear end of the telescopic connecting rod 12. A certain gap is provided between the outer wall of the mounting lug 121 and the inner wall of the sleeve 11. The end of the mounting lug 121 facing away from the telescopic connecting rod 12 is provided with an arc surface, which makes the mounting lug 121 smaller and does not occupy too much space in the sleeve 11. A mounting groove 122 is defined on the side of the mounting lug 121 adjacent to the signal transmission channel 111 of the casing 11. The first sensing element 21 is mounted within the mounting groove 122, and the first sensing element 21 does not protrude beyond the mounting groove 122. This prevents the first sensing element 21 from interfering with the inner wall of the casing 11 during the sliding and retracting of the telescopic connecting rod 12. In another embodiment, the first sensing element 21 can be directly mounted on the outer wall of the mounting lug 121, as long as the first sensing element 21 does not interfere with the inner wall of the casing 11.

[0034] In another embodiment, the first sensor 21 can be installed on the side of the telescopic connecting rod 12 near the rear end. In addition, a groove can be opened on the side of the telescopic connecting rod 12 near the rear end, and the first sensor will be installed in the groove.

[0035] Reference Figure 2 and Figure 4The second sensing element 22 is mounted on the inner wall of the signal transmission channel 111 and does not extend into the sleeve 11 to interfere with the sliding movement of the telescopic connecting rod 12. This arrangement further reduces the distance between the first sensing element 21 and the second sensing element 22. The signal transmission channel 111 can be a circular hole, a square hole, or an elongated hole extending in the same direction as the sliding movement of the telescopic connecting rod 12.

[0036] If the signal transmission channel 111 is a round hole or a square hole, then when the telescopic connecting rod 12 is extended to a preset length, the first sensing element 21 is located within the range of the round hole or the square hole, thereby making the transmission of the sensing signal more stable. If the signal transmission channel is an elongated hole, then when the first sensing element 21 moves within the range of the elongated hole, the sensing signal can be smoothly transmitted to the second sensing element 22, thereby allowing the second sensing element 22 to receive the sensing signal more promptly. In this embodiment, the signal transmission channel 111 is preferably an elongated hole.

[0037] Reference Figure 2 Furthermore, since the first sensing element 21 is located at the rear end of the telescopic connecting rod 12, in this embodiment, the signal transmission channel 111 preferably penetrates the sleeve 11 on the side near the rear end, but does not penetrate the sleeve 11 on the side near the front end. The second sensing element 22 is instead located on the inner wall of the signal transmission channel 111 near the front end. This arrangement, on the one hand, enhances the effectiveness of sensing signal transmission and reception for both the first sensing element 21 and the second sensing element 22 during the telescopic connecting rod 12's extension and retraction process; on the other hand, since the signal transmission channel 111 does not penetrate the front end of the sleeve 11, the sleeve 11's inherent strength is not significantly altered, thereby ensuring the stability of the sleeve 11 after connection to the child safety seat body.

[0038] The implementation principle of an ISOFIX mechanism in an embodiment of the present application is as follows: when the telescopic connecting rod 12 needs to be extended to connect with the car seat, the first sensing member 21 will move synchronously with the telescopic connecting rod 12, and the sensing signal emitted by the first sensing member 21 during the movement can be transmitted to the second sensing member 22 through the signal transmission channel 111 without being obstructed. As the telescopic connecting rod 12 moves, when the distance between the first sensing member 21 and the second sensing member 22 is less than a preset value, the second sensing member 22 can receive the sensing signal in time and sense each other with the first sensing member 21. At this time, the circuit board receives the signal from the second sensing member 22 and drives the light-emitting member 3 to light up, thereby improving the sensitivity when triggering the action of the second sensing member 22, thereby enabling the light-emitting member 3 to be lit in time for illumination.

[0039] In the second aspect, another embodiment of the present invention provides a child seat, referring to Figure 1 and Figure 2, comprising the aforementioned ISOFIX mechanism and a seat body 4, which includes a base 41 and a seat body 42 mounted on the base 41. A sleeve 11 is mounted within the base 41. The rear end of the base 41 defines an opening through which the telescopic connecting rod 12 can extend from the base 41 to connect with the car seat. A light-emitting element 3 is mounted at the rear end of the base 41. When the first sensing element 21 and the second sensing element 22 interact, the light-emitting element 3 illuminates the connection between the telescopic connecting rod 12 and the car seat.

[0040] In another embodiment, the seat body 4 may only include the seat body 42 , then the sleeve 11 will be installed in the seat body 42 , the telescopic connecting rod 12 will also extend from the rear end of the seat body 42 , and the corresponding light-emitting component 3 will also be installed at the rear end of the seat body 42 .

[0041] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
