[0036] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0037] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.
[0038] The following description, with reference to the accompanying drawings, describes a seat belt clamp device 100 and an infant car seat 200 having thereon according to an embodiment of the present invention.
[0039] like Figure 1 , Figure 2 and Figure 6As shown, the seat belt clamping device 100 according to the first aspect of the present invention includes a clamping member 1. One end of the clamping member 1 has a connecting portion, and the other end is equipped with a locking mechanism 2. The locking mechanism 2 includes a locking member 21, an operating member 22, a first elastic member 24, and a second elastic member 25. The locking member 21 is movably connected to the clamping member 1 and has a locking position and an unlocking position. The operating member 22 is movably connected to the clamping member 1 and has a driving portion 23. The driving portion 23 abuts against the locking member 21 to move the locking member 21 from the locking position to the unlocking position. The first elastic member 24 is connected between the operating member 22 and the clamping member 1, and makes the operating member 22 always have a tendency to reset. The second elastic member 25 is connected between the locking member 21 and the clamping member 1, and makes the locking member 21 always have a tendency to move from the unlocking position to the locking position.
[0040] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, the seat belt clamping device 100 in this embodiment of the invention includes a clamping member 1, which clamps or releases the seat belt. One end of the clamping member 1 has a connecting portion, which is connected to the seat body 101. The other end is equipped with a locking mechanism 2, which is used to lock or release the clamping member 1 and the seat body 101. The locking mechanism 2 includes a locking member 21, an operating member 22, a first elastic member 24, and a second elastic member 25. The locking member 21 is movably connected to the clamping member 1 and has a locking position and an unlocking position. In the locking position, the clamping member 1 clamps the seat belt onto the seat body 101, and the seat belt cannot move freely. In the unlocking position, the clamping member 1 releases the seat belt, and the seat belt can move freely. The operating member 22 is movably connected to the clamping member 1. The operating member 22 is equipped with a driving part 23, which abuts against the locking member 21 to move the locking member 21 from the locked position to the unlocked position. Operating the operating member 22 causes it to move relative to the clamping member 1, driving the driving part 23 to move. The driving part 23 pushes the locking member 21 to move from the locked position to the unlocked position. A first elastic member 24 is connected between the operating member 22 and the clamping member 1, ensuring that the operating member 22 always has a tendency to reset. This allows the operating member 22 to automatically reset under elastic force after operation, eliminating the need for manual reset and simplifying operation. A second elastic member 25 is connected between the locking member 21 and the clamping member 1, ensuring that the locking member 21 always has a tendency to move from the unlocked position to the locked position. This allows the locking member 21 to stably remain in the locked position under elastic force when locked, enabling the clamping member 1 to clamp the seatbelt.
[0041] Therefore, the seat belt clamp device 100 according to the present invention, by providing a driving part 23 on the operating member 22, allows the driving part 23 to move relative to the clamping member 1 as the operating member 22 moves. This eliminates the need for a dedicated movable connection structure between the driving part 23 and the clamping member 1, simplifying the connection structure and reducing the precision requirements of the overall structure, thus facilitating manufacturing. The driving part 23 abuts against the locking member 21, allowing the locking member 21 to move from the locked position to the unlocked position, thereby opening the clamping member 1. As a linkage structure, the driving part 23 prevents accidental unlocking by infants and young children, improving the safety of infants and young children while traveling.
[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, clamping component 1 has a long strip-shaped structure.
[0043] In some embodiments, such as Figure 6 As shown, both the first elastic element 24 and the second elastic element 25 are torsion springs. Of course, this solution is not limited to this; the first elastic element 24 and the second elastic element 25 can also be other elastic structures, as long as they can achieve the above-mentioned functions.
[0044] In some embodiments of the present invention, such as Figure 2 and Figure 6 As shown, the clamping member 1 is provided with a first rotating shaft 11. The locking member 21 and the operating member 22 are both sleeved on the first rotating shaft 11 and pivotally connected to the first rotating shaft 11. By sleeved on the first rotating shaft 11, the locking member 21 and the operating member 22 can pivot along the same rotating shaft, so that the pivoting trajectories of the surfaces of the driving part 23 and the locking member 21 that abut against each other are the same, which is beneficial for the locking member 21 to move under the drive of the driving part 23 to release the lock.
[0045] In some embodiments, such as Figure 6 As shown, the clamping member 1 has a mounting groove at one end connected to the locking mechanism 2. The operating member 22, the locking member 21, the first elastic member 24, and the second elastic member 25 are all located in the mounting groove and can move within it. The first rotating shaft 11 is fixed in the mounting groove along the width direction of the clamping member 1, and the first elastic member 24 and the second elastic member 25 are both sleeved on the first rotating shaft 11.
[0046] In some embodiments of the present invention, such as Figure 4As shown, the locking component 21 includes a locking body 211, a locking hook 212, and an abutment portion 213. The locking body 211 is sleeved on the first rotating shaft 11. The locking hook 212 extends from the locking body 211 to one side and is used to achieve the locking function. The abutment portion 213 is connected to the locking body 211 and abuts against the driving part 23 so as to pivot with the first rotating shaft 11 under the drive of the driving part 23. The abutment portion 213 is arranged towards the side away from the locking hook 212 for easy production and processing.
[0047] In some embodiments, such as Figure 4 As shown, the locking body 211 includes two identical and parallel locking units. Each locking unit has a through hole through which it is fitted onto the first rotating shaft 11. A locking hook 212 extends from each locking unit, and the locking hooks 212 on both locking bodies 211 face the same direction for locking. An abutment portion 213 connects the two locking units.
[0048] Of course, this solution is not limited to this. In other embodiments, the locking body 211 may include only one locking body 211 or two or more locking bodies 211 arranged in parallel.
[0049] Preferred, such as Figure 4 As shown, a groove is provided on the abutment portion 213 at the position where it connects with the second elastic member 25 to accommodate one end of the second elastic member 25, preventing one end of the second elastic member 25 from sliding along the abutment portion 213, which is beneficial for the stable locking and unlocking of the locking member 21.
[0050] In some embodiments of the present invention, such as Figure 3 As shown, the driving unit 23 includes a long plate-shaped driving surface, and the abutting part 213 includes a long plate-shaped abutting surface. The driving surface and the abutting surface are perpendicular. By setting the driving surface and the abutting surface perpendicularly, the contact surface between the driving surface and the abutting surface is prevented from changing due to machining accuracy or installation accuracy, thus avoiding affecting the driving effect. This allows the driving unit 23 to drive the abutting part 213 stably, reducing the requirements for machining accuracy and installation accuracy.
[0051] In some embodiments, such as Figure 3 As shown, the drive unit 23 is a long plate-shaped structure and is integrally formed on the operating member 22. Both sides of the drive unit 23 are provided with reinforcing ribs, which connect the operating member 22 and the drive unit 23.
[0052] In some embodiments of the present invention, such as Figure 3 and Figure 5As shown, the operating component 22 includes an operating body 221, which is rotatably connected to the first rotating shaft 11. A drive unit 23 is connected to the lower side of the operating body 221. A protrusion 222 is provided on the upper surface of the operating body 221, which is used to match the notch on the label. By providing the protrusion 222 on the upper surface of the operating body 221, when labeling is applied to the upper surface of the operating body 221, the notch on the label engages with the protrusion 222, preventing the label from being applied in the wrong direction and facilitating labeling.
[0053] It should be noted that the label is used to indicate how the operating component 22 is used. For example, the operating position, operating direction, etc.
[0054] Of course, it is understandable that other structures can be used to replace the protrusion 222, such as engraving or printing patterns.
[0055] Preferably, the protrusion 222 is integrally formed on the operating body 221.
[0056] In some embodiments, such as Figure 3 As shown, the operating component 22 also includes an arc-shaped plate, which is integrally formed on the lower side of the operating body 221. The arc-shaped plate is part of the arc surface formed around the first rotating shaft 11, and the distance between the arc-shaped plates in its width direction is the same. Two limiting plates are provided opposite to each other in the mounting groove along the width direction of the clamping component 1. The distance between the two limiting plates is the same as the width of the arc-shaped plate. The arc-shaped plate is limited by the limiting plates, so that the operating component 22 can pivot stably in a certain direction.
[0057] In some embodiments of the present invention, such as Figure 9 As shown, the seat belt clamping device 100 also includes a reinforcing tube 3. The clamping member 1 has a hollow structure, and the reinforcing tube 3 is fixedly connected inside the clamping member 1. By providing the reinforcing tube 3, the strength of the clamping member 1 is increased.
[0058] In some embodiments, the clamping member 1 has a U-shaped structure with the open end located at the bottom, and the reinforcing tube 3 is located inside the clamping member 1 and riveted to the clamping member 1.
[0059] like Figure 7 and Figure 8 As shown, the infant car seat 200 according to the second aspect of the present invention includes a seat body 101, a seat belt clamp device 100 and a locking member 102 in the above embodiment. One end of the clamping member 1 is pivotally connected to the seat body 101 through a connecting portion. When the locking member 21 is in the locked position, the locking member 102 cooperates with the locking member 21 to restrict the pivoting of the clamping member 1 relative to the seat body 101.
[0060] Specifically, one end of the clamping member 1 is pivotally connected to the seat body 101 via a connecting part, so that after the locking mechanism 2 is released, the end of the clamping member 1 connected to the locking mechanism 2 can move away from the seat body 101, so that the clamping member 1 releases the seat belt. When the locking member 21 is in the locked position, the locking member 102 cooperates with the locking member 21 to restrict the pivoting of the clamping member 1 relative to the seat body 101, thereby making the clamping member 1 clamp the seat belt on the seat body 101.
[0061] The infant car seat 200 according to the present invention improves the safety of use by adopting the seat belt clamp device 100 in the above embodiment, while having a simple structure, high overall stability, and extended service life.
[0062] In some embodiments of the present invention, such as Figure 10 As shown, the seat body 101 is provided with a clamping groove 103 corresponding to the clamping member 1. The locking member 102 is disposed in the clamping groove 103. When the locking member 21 is in the locked position, the clamping member 1 is located in the clamping groove 103. By providing the clamping groove 103 on the seat body 101, and ensuring that the clamping member 1 is located in the clamping groove 103 when the locking member 21 is in the locked position, the clamping member 1 will not protrude from the surface of the seat body 101, thus maintaining the flatness of the surface of the seat body 101 and improving the comfort of the seat.
[0063] In some embodiments of the present invention, such as Figure 10 As shown, the locking component 102 is a crossbar. Specifically, the crossbar is fixed in the clamping groove 103 along the width direction of the clamping groove 103. The crossbar has a simple structure and is easy to cooperate with the locking hook 212.
[0064] In some embodiments of the present invention, a fixing member 104 is fixedly connected to the end of the clamping groove 103 away from the locking member 102, and the fixing member 104 is connected to the connecting part through a second rotating shaft. Specifically, the fixing member 104 includes a fixing plate and fixing ears. There are two fixing ears, which are vertically arranged on opposite sides of the fixing plate. The fixing ears are provided with connecting holes. The connecting part consists of two through holes arranged on opposite sides of the clamping member 1. The second rotating shaft passes through the two through holes and is connected to the clamping member 1. The fixing ears are connected to the second rotating shaft through the connecting holes.
[0065] In some embodiments of the present invention, a third elastic member 105 is connected between the fixing member 104 and the clamping member 1. The third elastic member 105 causes the clamping member 1 to always tend to move in a direction away from the seat body 101. By providing the third elastic member 105, after the locking member 21 is released, the clamping member 1 can automatically move in a direction away from the seat body 101 without manual operation, which is convenient to use.
[0066] In some embodiments, the third elastic element 105 is a torsion spring.
