Description

Technical Field

[0001] The present application relates to the field of child seat technology, and in particular to a belt clip for a safety seat. Background Art

[0002] Generally speaking, there are three ways to fix child safety seats in vehicles, namely seat belt fixation, ISOFIX fixation, and LATCH fixation. Among them, ISOFIX fixation and LATCH fixation require the vehicle to have ISOFIX interface and LATCH interface respectively. There are fewer vehicles with ISOFIX interface and LATCH interface, while vehicles with seat belts are more common, making child safety seats fixed with seat belts more versatile.

[0003] Typically, a safety seat includes a seat and a backrest. The seat is provided with a seat belt guide plate, and the backrest is provided with a seat belt guide groove. The seat belt is fixed by passing one seat belt through the seat belt guide plate of the seat and connecting it to the seat belt buckle of the original seat, and the other seat belt is passed from the seat belt buckle through the seat belt guide groove of the backrest. In this way, the safety seat is firmly fixed to the original seat.

[0004] In the prior art, although the safety belt can be confined within the safety belt guide plate or the safety belt guide groove of the safety seat, the stability of the confined safety belt still has room for further improvement. Utility Model Content

[0005] In view of this, the present application provides a belt clip for a safety seat, which can enable a safety belt to be conveniently and securely installed on a safety seat, thereby ensuring the safety of the safety seat.

[0006] In order to improve the convenience and stability of safety seat installation, the present application provides a safety seat belt clip.

[0007] The present application provides a safety seat belt clamp adopting the following technical solution:

[0008] A belt clamp for a safety seat comprises a mounting shell and a locking mechanism. The mounting shell is provided with an opening for a safety belt to pass through. The locking mechanism is connected to the mounting shell and is at least partially located in the opening. The locking mechanism is used to limit the movement of the safety belt in the opening.

[0009] By adopting the above technical solution, the user places the safety belt into the opening in the mounting shell, and the movement of the safety belt in the opening is restricted by the locking mechanism. In this way, the safety belt is firmly set in the opening of the mounting shell. The mounting shell is fixed to the backrest of the safety seat, so that the safety seat can firmly and conveniently confine the seat and back of the safety seat in the safety seat belt clamp through the safety belt, thereby increasing the safety of the safety seat.

[0010] Preferably, the locking mechanism includes a limiting body and a locking member, the limiting body is at least partially located in the opening, one end of the limiting body located in the opening is movably connected to the mounting shell, the end of the limiting body away from the opening is connected to the locking member, and the locking member is also connected to the mounting shell, so that the locking member can limit the relative position of the limiting body and the mounting shell.

[0011] By adopting the above technical solution, the user first opens the locking piece so that the limiting body can move in the opening, so that the opening has a maximum gap suitable for inserting the safety belt, which facilitates the convenient insertion of the safety belt. Then, the user puts the safety belt into the opening in the mounting shell. The user moves the position of the limiting body so that the limiting body limits the position of the safety belt in the opening. Finally, the user locks the position between the limiting body and the mounting shell through the locking piece. In this way, the safety belt is firmly restricted by the limiting body in the opening of the mounting shell, thereby achieving a stable installation of the safety seat.

[0012] Preferably, the mounting shell is provided with a first groove on the inner wall of the opening, the limiting body is provided with a first protrusion, a second protrusion is provided on the upper part of the first protrusion, the first protrusion is at least partially located in the first groove, and the second protrusion is located in the first groove.

[0013] By adopting the above technical solution, on the one hand, the movable space of the safety belt is limited by the first protrusion and the first groove on the limiting body, and the path of the safety belt passing through the opening is made relatively curved, which is convenient for increasing the friction between the safety belt and the inner wall of the installation shell opening, and increasing the stability of the connection between the safety belt and the seat. On the other hand, through the cooperation of the second protrusion and the first groove, the upper part of the safety belt is sealed by the second protrusion and the first groove, so that the safety belt will not fall off the belt clip, thereby increasing the safety of the safety seat installed through the safety belt.

[0014] Preferably, a second groove is formed on the first protrusion.

[0015] By adopting the above technical solution and providing the second groove, the friction between the first protrusion and the safety belt is increased, thereby increasing the stability of the connection between the safety belt and the seat.

[0016] Preferably, the opening includes a limiting cavity for accommodating the limiting body and an opening cavity for the safety belt to pass through, the limiting cavity is located in the middle of the opening cavity, and the limiting cavity is connected to the opening cavity; the vertical cross-section of the limiting cavity is shaped like an inverted right-angled trapezoid, and the side of the cross-section of the limiting cavity close to the opening cavity is a right-angled side, and the side of the cross-section of the limiting cavity far from the opening cavity is a hypotenuse.

[0017] By adopting the above technical solution, through the communication between the limiting cavity and the opening cavity, the user can move the limiting body to change the gap in the opening for the safety belt to pass through, and then when the safety belt is installed or removed, the opening has the maximum gap when the safety belt is inserted or removed, thereby facilitating the installation or removal of the safety belt; the inverted right-angled trapezoidal limiting cavity allows the limiting body to have a larger movable space.

[0018] Preferably, the locking member is a buckle, the buckle is connected to an end of the limiting body away from the opening, and a third protrusion for cooperating with the buckle is provided on the mounting shell.

[0019] By adopting the above technical solution, the position of the limiting body is limited by the connection between the buckle and the third protrusion, so that the limiting body always maintains the state of limiting the seat belt, and the position of the limiting body is limited by the buckle and the third protrusion, which makes it easier to lock or unlock the limiting body of the locking member.

[0020] Preferably, the mounting shell is movably connected to a limiting member, and the limiting member is provided with a fourth protrusion, and the fourth protrusion is used to limit the movement of the buckle.

[0021] By adopting the above technical solution, the movement of the buckle is restricted by the fourth protrusion, thereby ensuring that the buckle will not be accidentally unlocked, thereby further increasing the safety of the safety seat.

[0022] Preferably, the locking member includes a torsion spring and a clamp, the torsion spring is connected to the limiting body, the clamp is connected to the torsion spring, and a third protrusion is provided on the mounting shell, and the third protrusion cooperates with the clamp.

[0023] By adopting the above technical solution, the position of the limiting body is limited by the connection between the buckle and the third protrusion, so that the limiting body always maintains the state of limiting the seat belt, and the position of the limiting body is limited by the buckle and the third protrusion, which makes it easier to lock or unlock the limiting body of the locking member.

[0024] Preferably, a limiting member is movably connected to the mounting shell, and a fourth protrusion is provided on the limiting member, and the fourth protrusion is used to limit the movement of the clamp.

[0025] By adopting the above technical solution, the movement of the clamp is limited by the fourth protrusion, ensuring that the clamp will not be accidentally unlocked, thereby further increasing the safety of the safety seat.

[0026] Preferably, the inner diameters of the two ends of the open cavity are larger than the inner diameter of the middle portion of the open cavity; and the mounting shell is further provided with fifth protrusions at the two ends of the open cavity.

[0027] By adopting the above technical solution, the inner diameters on both sides of the opening cavity are larger, which makes it easier for the user to insert the seat belt into the mounting shell through the two ends of the opening cavity, thereby accelerating the connection process between the seat belt and the belt clip. In addition, the fifth protrusion not only increases the tortuosity of the path of the seat belt in the opening to increase the connection between the seat belt and the belt clip, but also makes the seat belt and the belt clip have a larger contact area, increases the friction between the seat belt and the belt clip, and thereby increases the stability of the connection between the seat belt and the seat.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The user first opens the locking member to allow the limiting body to move within the opening, thereby creating a maximum gap in the opening suitable for inserting the seat belt, facilitating convenient insertion of the seat belt. The user then inserts the seat belt into the opening in the mounting shell. The user moves the limiting body so that the limiting body restricts the position of the seat belt within the opening. Finally, the user locks the limiting body and the mounting shell with the locking member. This secures the seat belt within the opening of the mounting shell and is thus securely restrained by the limiting body, thereby achieving a secure installation of the safety seat.

[0030] 2. On the one hand, the first protrusion and the first groove on the limiter body limit the movable space of the seat belt, and also make the path of the seat belt passing through the opening more curved, which helps to increase the friction between the seat belt and the inner wall of the installation shell opening, and enhance the stability of the connection between the seat belt and the seat. On the other hand, the second protrusion and the first groove cooperate to seal the upper part of the seat belt, so that the seat belt will not fall out of the belt clip, and enhance the safety of the safety seat when the seat belt is installed;

[0031] 3. The position of the restricting body is limited by the connection between the buckle and the third protrusion, so that the restricting body always keeps the state of restricting the seat belt, and the position of the restricting body is limited by the buckle and the third protrusion, which makes it easier to lock or unlock the restricting body of the locking member; the position of the restricting body is limited by the connection between the buckle and the third protrusion, so that the restricting body always keeps the state of restricting the seat belt, and the position of the restricting body is limited by the buckle and the third protrusion, which makes it easier to lock or unlock the restricting body of the locking member.

[0042] The following is combined with Figure 1-9 This application is described in further detail.

[0043] Example 1

[0044] The embodiment of the present application discloses a belt clip for a safety seat.

[0045] Reference Figure 1, including a mounting shell 1 and a locking mechanism 2, the mounting shell 1 is used to be connected to the seat back of the safety seat, so that the safety seat limits the position of the safety belt through the belt clip, thereby achieving stable installation of the safety seat, and an opening 3 for the safety belt to pass through is opened on the mounting shell 1, the locking mechanism 2 includes a limiting body 4 and a locking member 5, the limiting body 4 is at least partially located in the opening 3 of the mounting shell 1, the locking member 5 is located on the limiting body 4, and the locking member 5 can be connected to the mounting shell 1. When in use, the user puts the safety belt into the opening 3 in the mounting shell 1, and limits the movement of the safety belt in the opening 3 through the limiting body 4, and limits the relative position of the limiting body 4 and the mounting shell 1 through the locking member 5. In this way, the user firmly sets the safety belt in the opening 3 of the mounting shell 1, thereby increasing the safety of the safety seat being fixed to the vehicle through the safety belt.

[0046] refer to Figure 2 、 Figure 3 and Figure 4 The opening 3 of the mounting shell 1 includes a limiting cavity 10 for accommodating the limiting body 4 and an opening cavity 11 for passing the safety belt. The opening cavity 11 is a sheet-shaped cavity connecting the left and right sides of the mounting shell 1 and the upper side of the mounting shell 1, so that the user can insert the safety belt into the opening cavity 11 from the upper side of the opening cavity 11, thereby allowing the safety belt to pass through and out from the left and right sides of the mounting shell 1 respectively. The limiting cavity 10 is located in the middle of the opening cavity 11 of the mounting shell 1, and the limiting cavity 10 is connected to the opening cavity 11. After the limiting cavity 10 is cut along its vertical direction, the cross-sectional shape of the limiting cavity 10 is an inverted right-angled trapezoid, and the side of the limiting cavity 10 close to the opening cavity 11 is the right-angled side of the right-angled trapezoid, and the side of the limiting cavity 10 far from the cavity 11 is the hypotenuse of the right-angled trapezoid, that is, the cavity length of the upper part of the limiting cavity 10 is greater than the cavity length of the lower part of the limiting cavity 10.

[0047] The limiting body 4 is located in the limiting cavity 10, and the lower end of the limiting body 4 is rotatably connected to the rotating shaft, which is also connected to the mounting shell 1, thereby making the limiting body 4 rotatably connected to the mounting shell 1, and the mounting shell 1 is also integrally formed with a rotating shaft protrusion in the limiting cavity 10, and the rotating shaft is just located at the rotating shaft protrusion. The rotating shaft protrusion strengthens the supporting strength of the mounting shell 1 to the rotating shaft, thereby making the limiting body 4 able to rotate at a fixed point in the mounting shell 1, and the inverted trapezoidal limiting cavity 10 is just adapted to the limiting body 4 rotating at the vertex, so that the limiting body 4 can be rotated so that the opening cavity 11 has a shape that is convenient for the safety belt to be placed. The maximum gap for entry is formed, and it is convenient for the limiting body 4 to rotate back to limit the space in the opening cavity 11 for the safety belt to be placed, thereby limiting the position of the safety belt in the opening cavity 11. The lower end of the limiting body 4 is provided with a stepped groove at a position away from the opening cavity 11. The limiting body 4 reduces its own collision with the inner wall of the limiting cavity 10 during the rotation process through the setting of the stepped groove, and a plurality of through holes are provided on the limiting body 4, which is conducive to reducing the weight of the limiting body 4, thereby saving production raw materials and reducing production costs. The upper end of the limiting body 4 is integrally formed with a sixth protrusion 24, which is used to connect with the locking member 5.

[0048] refer to Figure 5 and Figure 6 The locking member 5 can be a buckle 12, which is arranged on the sixth protrusion 24 of the limiting body 4. The mounting shell 1 is integrally connected with a third protrusion 13. The buckle 12 cooperates with the third protrusion 13 of the mounting shell 1, so that the user shell connects the buckle 12 with the third protrusion 13, thereby limiting the position of the limiting body 4 and the mounting shell 1, so that after the seat belt is restricted in the opening 11 by the limiting body 4, the limiting body 4 is restricted by the buckle 12, thereby making the seat belt firmly connected to the belt clip, and thus making the safety seat firmly installed on the vehicle through the seat belt.

[0049] Further, in this embodiment, reference Figure 1 and Figure 7 The upper side of the mounting shell 1 is slidably connected to a limit member 14 on one side of the opening 3. The limit member 14 is provided with a fourth protrusion 15 on the side close to the locking member 5. The fourth protrusion 15 is in a "7" shape, so that the fourth protrusion 15 can limit the upward movement of the buckle 12 and limit the movement of the buckle 12 in the direction away from the third protrusion 13, thereby ensuring that the buckle 12 will not be accidentally unlocked, thereby further increasing the safety of the safety seat.

[0050] Furthermore, in this embodiment, the present invention has no special restrictions on the specific structure of the buckle 12. The buckle 12 structure that is familiar to those skilled in the art and can realize the convenient connection or unlocking function between the limiting body 4 and the mounting shell 1 can be used. Those skilled in the art can select and adjust it according to the specific application situation and product requirements.

[0051] Furthermore, in this embodiment, the limiting body 4 is integrally connected with a first protrusion 7 on the side close to the opening cavity 11, and the connection between the lower part of the first protrusion 7 and the limiting body 4 is relatively smooth. The upper part of the first protrusion 7 is integrally formed with a second protrusion 8, and the upper part of the second protrusion 8 is chamfered to facilitate the safety belt to slide into the opening cavity 11, and the lower end of the second protrusion 8 is straight to facilitate the second protrusion 8 to intercept the safety belt and prevent the safety belt from running out. The opening cavity 11 is provided with a first groove 6 on the inner wall away from the end of the limiting cavity 10. The position of the first groove 6 is opposite to the first protrusion 7 and the second protrusion 8, and the first protrusion 7 is partially located in the first groove 6, and the second protrusion 8 is completely located in the first groove 6. When the safety belt needs to be placed in the opening 3, the user unlocks the locking member 5 and the installation The user then inserts the safety belt into the opening 11 from the upper side of the opening 11. After that, the user rotates the limiting body 4 so that the second protrusion 8 of the limiting body 4 is in sealing contact with the first groove 6. The upper part of the safety belt is sealed by the second protrusion 8, so that the safety belt will not escape from the clipper, thereby increasing the safety of the safety seat installed through the safety belt. Although the gap between the first protrusion 7 and the first groove 6 allows the safety belt to move appropriately in the opening 3, the first protrusion 7 increases the tortuosity of the path of the safety belt in the opening 3, thereby increasing the friction between the safety belt and the inner wall of the opening 3 of the installation shell 1, thereby increasing the stability of the connection between the safety belt and the seat.

[0052] Furthermore, in this embodiment, a second groove 9 is provided on the first protrusion 7. The first protrusion 7 is shaped like a quadrangular prism, and multiple second grooves 9 are provided at the edges of the first protrusion 7, so that the friction force at the edges of the first protrusion 7 is significantly increased, thereby increasing the stability of the connection between the seat belt and the seat.

[0053] Furthermore, in this embodiment, the mounting shell 1 includes a first vertical plate 19, a second vertical plate 20 and a first horizontal plate 21, the first vertical plate 19 and the second vertical plate 20 are arranged relative to each other (the first vertical plate 19 and the second vertical plate 20 are not necessarily parallel to each other), the first horizontal plate 21 is connected to the upper ends of the first vertical plate 19 and the second vertical plate 20, the first vertical plate 19, the second vertical plate 20 and the first horizontal plate 21 are all integrally formed, and the first vertical plate 19 and the second vertical plate 20 have corners, which facilitates the turning of the mounting shell 1 and the seat back. The upper side of the mounting shell 1 is provided with an inverted "U"-shaped groove 22 for bolting the mounting shell 1 to the safety seat; the lower end of the first vertical plate 19 is integrally formed with a second horizontal plate 23, which is convenient for strengthening the strength of the first vertical plate 19 and, on the other hand, for facilitating the bolt connection of the mounting shell 1 to the safety seat; a "U"-shaped piece is provided in the "U"-shaped groove 22, and the "U"-shaped piece just fills the "U"-shaped groove 22, thereby increasing the smoothness of the appearance of the belt clamp and thereby increasing the overall aesthetics of the belt clamp.

[0054] Furthermore, in this embodiment, the intracavity gaps at both ends of the open cavity 11 are larger than the intracavity gaps in the middle of the open cavity 11, and the larger inner diameters on both sides of the open cavity 11 make it easier for the user to insert the safety belt into the mounting shell 1 through both ends of the open cavity 11, thereby accelerating the connection process between the safety belt and the belt clamp; and the cross-sectional shape at both ends of the open cavity 11 is a right-angled triangle, that is, at the end of the open cavity 11, the intracavity gap in the upper part of the open cavity 11 is smaller than the intracavity gap in the lower part of the open cavity 11, so that the safety belt can be easily placed in the open cavity 11, and the safety belt is not easy to detach from the cavity 11 by itself.

[0055] Furthermore, in this embodiment, the mounting shell 1 is further provided with a fifth protrusion 18 on the inner walls at both ends of the opening cavity 11. The fifth protrusion 18 not only increases the tortuosity of the path of the seat belt in the opening 3 to increase the connection between the seat belt and the belt clamp, but also makes the seat belt and the belt clamp have a larger contact area, increases the friction between the seat belt and the belt clamp, and thereby increases the stability of the connection between the seat belt and the seat.

[0056] Furthermore, in this embodiment, the mounting shell 1 is provided with a recessed groove 25 at its opening 3, so that the locking member 5 at the upper end of the limiting body 4 is also located in the recessed groove 25, and the third protrusion 13 for cooperating with the locking member 5 is also located in the recessed groove 25, thereby making the appearance of the belt clamp relatively smooth, and increasing the overall aesthetics of the belt clamp.

[0057] Example 2

[0058] The difference between this embodiment and embodiment 1 mainly lies in the specific structure of the locking member 5 .

[0059] refer to Figure 1 、 Figure 8 and Figure 9 In this embodiment, the locking member 5 includes a torsion spring 16 and a clamp 17. The torsion spring 16 is connected to the sixth protrusion 24 on the upper end of the limiting body 4. The clamp 17 is connected to the torsion spring 16. The end of the clamp 17 cooperates with the third protrusion 13 of the mounting shell 1, so that the user can press the clamp 17 of the locking member 5 to make the clamp 17 hook, lock or unlock, thereby limiting or changing the relative position of the limiting body 4 and the mounting shell 1.

[0060] Further, in this embodiment, reference Figure 1 and Figure 7 The upper side of the mounting shell 1 is slidably connected to a limit member 14 on one side of the opening 3. The limit member 14 is provided with a fourth protrusion 15 on the side close to the locking member 5. The fourth protrusion 15 is in a "7" shape, so that the fourth protrusion 15 can limit the upward movement of the clamp 17 and limit the movement of the clamp 17 in the direction away from the third protrusion 13, thereby ensuring that the clamp 17 will not be accidentally unlocked, thereby further increasing the safety of the safety seat.

[0061] It should be noted that the various embodiments of the present application can be arbitrarily combined into new embodiments if the solutions do not conflict and the technical solutions can coexist.

[0062] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
