Description
Technical Field
[0001] This application relates to the field of child restraint systems technology, and more specifically to an ISOFIX connection device with an embedded switch. Background Technology
[0002] Most car seats are equipped with interfaces for installing child car seats, the most common being ISOFIX interfaces. These interfaces are used to connect child restraint systems (child safety seats) to the car seat, making the installation of child safety seats quick and easy, and providing a rigid connection for enhanced safety.
[0003] ISOFIX connection devices typically include an ISOFIX connector sleeve and an ISOFIX connector rod, which can be connected by a control switch to control the locking and unlocking of the two, thereby achieving telescopic positioning.
[0004] However, existing ISOFIX connection devices have the following drawbacks: the control switches commonly found at present usually extend to the outside of the ISOFIX connection sleeve, which makes the ISOFIX connection device occupy a larger volume of external space, which may interfere with the connection between the child safety seat and the car seat, and the control switches may interfere with the car seat, resulting in increased difficulty of operation. Utility Model Content
[0005] One object of this application is to provide an ISOFIX connection device with an embedded switch that is easy to operate and has a compact structure.

[0007] In some embodiments, the operating member has an operating port, and the operating port is always exposed inside the external through hole when the operating member slides.
[0008] In some embodiments, the operating port is convex around its perimeter to form an operating ring, and the operating ring and the stop portion are staggered in the depth direction of the external through hole. When the operating member rotates, the stop portion is adapted to disengage from the external through hole before the operating ring.
[0009] In some embodiments, when the operating member rotates, the operating ring is always located inside the external through hole; the distance between the outermost parts of the operating ring and the stop portion in the first direction is not greater than the width of the external through hole in the first direction; the operating ring and the stop portion are spaced apart along the first direction; the shape of the operating ring is adapted to the shape of the external through hole, and the shape of the abutting side of the stop portion is adapted to the shape of the external through hole.
[0010] In some embodiments, a first elastic reset member is provided between the second end of the operating member and the housing, and the stop portion is provided at the second end of the operating member. The first elastic reset member is adapted to rotate the second end of the operating member toward the external through hole, and / or, a first elastic reset member is provided at the rotational connection between the operating member and the linkage member.
[0011] In some embodiments, the operating member has an operating port, the operating port is convex around its perimeter and forms an operating ring, and the first elastic reset member is adapted to move the operating ring toward the external through hole.
[0012] In some embodiments, the first end of the operating member is rotatably sleeved on the outer side of the end of the linkage member, the first end of the operating member protrudes circumferentially to form a first guide portion, and a first guide groove is provided in the housing, the first guide portion being adapted to be rotatably embedded in the first guide groove.
[0013] In some embodiments, a second elastic reset member is provided between the locking member and the linkage member. The second elastic reset member is adapted to bring the locking member and the linkage member closer to each other. The locking member has a locking groove for accommodating the end of the linkage member. When the linkage member disengages from the locking groove, the second elastic reset member is adapted to rotate the locking member and restrict the locking groove and the end of the linkage member.
[0014] In some embodiments, a second guide groove is provided in the housing on one or both sides of the linkage member, and a second guide portion is provided on one or both sides of the linkage member near one end of the locking member, the second guide portion being adapted to be slidably embedded in the second guide groove.

[0023] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0024] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.
[0025] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0026] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0027] The following description, in conjunction with the accompanying drawings, further illustrates this application: like Figures 1 to 5As shown, this application provides an ISOFIX connection device embedded in a switch, including an ISOFIX connecting rod that mates with an ISOFIX connecting sleeve. The ISOFIX connecting rod includes a housing 1, with a connection port 11 at one end and an external through hole 121 on one side. Inside the housing 1, a rotatable locking member 2, a sliding linkage member 3, and an operating member 4 are sequentially arranged from the connection port 11 to the external through hole 121. The locking member 2 is adapted to rotate and be exposed to the connection port 11 for locking. The rotation state of the locking member 2 is linked to the sliding state of one end of the linkage member 3. The operating member 4 is adapted to be exposed to the external through hole 121. The first end 41 of the operating member 4 is rotatably connected to the other end of the linkage member 3. The user can contact and control the sliding of the operating member 4 through the external through hole 121, thereby driving the linkage member 3 to move, and finally realizing the locking and unlocking of the locking member 2. The hidden design of the operating member 4 can reduce the occupation of external space and improve the structural compactness.
[0028] The operating member 4 is provided with a stop 42, which is adapted to be exposed in the external through hole 121 and abut against the external through hole 121 at least in the first direction. The operating member 4 is adapted to rotate so that the stop 42 is released from abutment against the external through hole 121. It is understood that the sliding control of the operating member 4 lacks a locking structure. Although the operating member 4 is built-in and the probability of misoperation is low, misoperation may still occur. This application improves the stability and safety of the operating member 4 by providing a stop 42 and making the operating member 4 rotatable. This allows the operating member 4 to achieve a locking effect by rotating the stop 42.
[0029] In some embodiments, the first direction is the length direction of the ISOFIX connecting rod. Since the ISOFIX connecting rod and the ISOFIX connecting sleeve are generally connected by sliding nesting, and the sliding direction is the length direction of the ISOFIX connecting rod, setting the sliding direction of the linkage 3 and the operating member 4 to the length direction of the ISOFIX connecting rod can better adapt to the movement of the ISOFIX connecting rod and conform to the user's operating intuition.
[0030] like Figures 2 to 3 In the embodiment shown, the operating member 4 is provided with an operating port 43, which is convenient for user control. When the operating member 4 slides, the operating port 43 is always exposed in the external through hole 121, ensuring that the operating port 43 can always be operated and controlled by the user, and avoiding obstruction and interference from the housing 1 during the sliding process of the operating member 4.
[0031] like Figures 2 to 4In the illustrated embodiment, the operating port 43 is convex around its perimeter, forming an operating ring 44. The operating ring 44 can increase the depth of the operating port 43, reducing the difficulty of operation for the user. The operating ring 44 and the stop part 42 are staggered in the depth direction of the external through hole 121. Specifically, when the operating member 4 rotates to be parallel to the external through hole 121, the operating ring 44 protrudes from the stop part 42 in the depth direction of the external through hole 121. When the operating member 4 rotates, the stop part 42 is adapted to disengage from the external through hole 121 before the operating ring 44, so that the stop part 42 can disengage from the external through hole 121 with a shorter stroke and release the restriction on the sliding of the operating member 4.
[0032] like Figure 2 and 3 In the embodiment shown, when the operating member 4 rotates, the operating ring 44 is always located inside the external through hole 121, ensuring that the operating ring 44 can always be observed and operated by the user, thereby improving the convenience of operation.
[0033] Specifically, by setting the thickness of the operating member 4 and the height of the operating ring 44, when the operating member 4 rotates to its maximum stroke, for example, when it touches the housing 1, it is ensured that the operating ring 44 can still be located inside the external through hole 121 in this state.
[0034] This allows the operating ring 44 to abut against the external through hole 121 on the side of the first end 41 of the operating member 4 when it slides after being rotated, thereby limiting the sliding stroke of the operating member 4 and providing operational feedback.
[0035] like Figure 2 In the embodiment shown, the distance X between the outermost parts of the operating ring 44 and the stop part 42 in the first direction is not greater than the width Y of the external through hole 121 in the first direction, ensuring that the operating ring 44 and the stop part 42 can both be fully inserted into the external through hole 121, thus ensuring the normal use and operation of the operating ring 44 and the stop part 42.
[0036] like Figures 2 to 5 In the embodiment shown, the operating ring 44 and the stop portion 42 are spaced apart along the first direction, so that after the stop portion 42 disengages from the external through hole 121, the operating ring 44 can obtain sufficient travel to drive the linkage 3 to move, ensuring the smooth unlocking of the locking member 2.
[0037] It is understandable that the operating ring 44 and the stop part 42 are not spaced apart, but the stop part 42 has sufficient width in the first direction, which can also enable the operating ring 44 to have sufficient travel.
[0038] like Figure 1 and 4In the embodiment shown, the shape of the operating ring 44 is adapted to the shape of the external through hole 121, and the shape of the abutting side of the stop portion 42 is adapted to the shape of the external through hole 121. This can effectively reduce the contact collision wear between the operating ring 44 and the stop portion 42 and the external through hole 121, and can also improve the structural compactness and reduce space occupation.
[0039] Specifically, in this application, the external through hole 121 is set as an oblong hole, which is aesthetically pleasing and does not feel uncomfortable to the touch. Therefore, the operating ring 44 can be set as an arc shape on both sides along the first direction to match the external through hole 121, and the abutting side of the stop part 42 is set as an arc shape.
[0040] In some embodiments, a first elastic reset member 5 is provided between the second end 45 of the operating member 4 and the housing 1, and a stop portion 42 is provided at the second end 45 of the operating member 4. The first elastic reset member 5 is adapted to rotate the second end 45 of the operating member 4 toward the external through hole 121, and / or, a first elastic reset member is provided at the rotational connection (rotating shaft) between the operating member 4 and the linkage member 3.
[0041] It is understandable that either of the two types of first elastic reset elements can be selected for setting, both of which can achieve a similar reset effect, or they can be set simultaneously, which can greatly improve the rotational reset capability of the operating element 4.
[0042] like Figure 2 and 3 In the embodiment shown, the first elastic reset member 5 is adapted to move the operating ring 44 toward the external through hole 121, so that the operating ring 44 can be moved back into the external through hole 121, making it convenient for the user to perform the next unlocking operation.
[0043] In some embodiments, the first elastic reset member 5 provided between the second end 45 of the operating member 4 and the housing 1 is a compression spring, and the first elastic reset member 5 provided at the rotational connection between the operating member 4 and the linkage member 3 is a torsion spring.
[0044] like Figures 2 to 5 In the embodiment shown, the first end 41 of the operating member 4 is rotatably sleeved on the outer side of the end of the linkage member 3. The first end 41 of the operating member 4 protrudes circumferentially to form a first guide portion 411. A first guide groove 15 is provided inside the housing 1. The first guide portion 411 is adapted to be rotatably embedded in the first guide groove 15.
[0045] It is understandable that the cooperation between the first guide part 411 and the first guide groove 15 can enhance the stability of the rotational connection between the operating member 4 and the linkage member 3, reduce the shaking and displacement of the operating member 4, and effectively improve the stability of the rotation of the operating member 4 relative to the linkage member 3.
[0046] like Figure 4 and 5In the illustrated embodiment, a second elastic reset member 6 is provided between the locking member 2 and the linkage member 3. The second elastic reset member 6 is adapted to bring the locking member 2 and the linkage member 3 closer to each other. The locking member 2 is provided with a locking groove 21 for accommodating the end of the linkage member 3. When the linkage member 3 disengages from the locking groove 21, the second elastic reset member 6 is adapted to make the locking member 2 rotate and restrict the locking groove 21 and the end of the linkage member 3. The second elastic reset member 6 enables the states of the locking member 2 and the linkage member 3 to be linked, thereby directly associating the locking action of the locking member 2 with the sliding action of the linkage member 3, so as to further realize the remote linkage control of the locking action of the locking member 2.
[0047] In some embodiments, the second elastic reset member 6 is a tension spring.
[0048] In some embodiments, the housing 1 has a second guide groove 16 on one or both sides of the linkage 3, and a second guide portion 31 is provided on one or both sides of the linkage 3 near the locking member 2. The second guide portion 31 is adapted to be slidably embedded in the second guide groove 16. Since the locking state of the linkage 3 near the locking member 2 is associated with the locking state of the locking member 2, the stability of the linkage 3 near the locking member 2 will also affect the stability of the locking state of the locking member 2. This application strengthens the fit at this point by providing the second guide groove 16 and the second guide portion 31, which can effectively improve the connection locking stability of the ISOFIX connection device.
[0049] It is understandable that the housing 1 and the linkage 3 are like Figure 4 The second guide portion 31 and the second guide groove 16 are provided on both sides for connection, which enables the linkage 3 to obtain higher sliding stability.
[0050] It is understandable that the housing 1 has a second guide part 31 on one or both sides of the linkage 3, and the linkage 3 has a second guide groove 16 on one or both sides near the locking part 2, which can also achieve a similar or even the same effect.
[0051] like Figures 1 to 4 In the embodiment shown, the housing 1 includes a first housing 12, a second housing 13, and an outer shell 14. The first housing 12 and the second housing 13 are adapted to be interlocked and assembled along their four perimeters to accommodate the locking member 2, the linkage member 3, and the operating member 4. The outer shell 14 is adapted to be nested on the outside of the combined first housing 12 and the second housing 13. The first housing 12, the second housing 13, and the outer shell 14 are connected and assembled in the above manner, which has high structural strength and structural stability and is not easily deformed or moved.
[0052] like Figure 2In the embodiment shown, the external through hole 121 is formed on the first housing 12. The outer shell 14 can have a through hole structure or a semi-open structure. When the outer shell 14 is nested outside the first housing 12 and the second housing 13, the outer shell 14 is suitable for blocking the stop part 42 to prevent foreign objects from getting stuck in the stop part 42 and affecting the normal operation of the stop part 42. It can also improve the overall aesthetics and integration of the ISOFIX connection device.
[0053] like Figure 4 In the embodiment shown, the outer sides of the first housing 12 and the second housing 13 and the outer shell 14 are respectively provided with snap-fit protrusions 17 and snap-fit grooves 18. The snap-fit protrusions 17 and snap-fit grooves 18 are adapted to engage and snap-fit to restrict the first housing 12 and the second housing 13 from coming off the outer shell 14, thereby improving the bonding stability between the first housing 12, the second housing 13 and the outer shell 14.
[0054] like Figures 2 to 5 In the embodiment shown, a blocking member 7 is provided at the end of the housing 1 away from the connection port 11. The blocking member 7 is adapted to limit the distance of the operating member 4 moving away from the connection port 11, which can prevent the operating member 4 from coming out of the housing 1 from that end, improve the structural stability, and also play a role in isolation and protection, preventing foreign objects from entering the housing 1 from that end. The shape of the blocking member 7 is adapted to the shape of the second end 45 of the operating member 4.
[0055] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are only the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope of this application. All such changes and modifications fall within the scope of this application as claimed. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
