DETAILED DESCRIPTION

[0038] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0039] The present application is further described in detail below with reference to the accompanying drawings.

[0040] Example 1:

[0041] like Figures 1 to 9 As shown, the present application provides a safety belt connection mechanism, which is installed on a seat or a safety cushion, and the seat or the safety cushion is provided with a safety belt, and the safety belt connection mechanism includes:

[0042] The safety belt connecting device 100 includes a connecting end 110 mounted on the safety belt and a plug-in end 120 that can be plugged into a seat or a safety cushion. The plug-in end 120 is provided with a lock hole 121.

[0043] The connecting portion 200 is mounted on the seat or safety cushion. The connecting portion 200 is provided with a plurality of plug holes 210 that can be detachably connected to the plug end 120. A locking member for locking the plug is provided in each plug hole 210.

[0044] The present application provides a connecting portion 200 on a seat or safety cushion in a vehicle or amusement ride, and connects a seatbelt connecting device 100 mounted on the seatbelt to the connecting portion 200. After the seatbelt is fastened in accordance with existing technical specifications, the seatbelt knot located on the abdomen is secured to the connecting portion 200 via the seatbelt connecting device 100. In the event of an accident or braking, the retraction force of the seatbelt is applied entirely to the passenger's thighs, preventing discomfort caused by compression of the passenger's abdomen during retraction. By providing multiple insertion holes 210 and locking members on the connecting portion 200, the plug end 120 can be connected to the insertion hole 210 at the appropriate location according to the passenger's body shape, and locked and secured by the locking member. This adaptability allows for passengers of varying body shapes, improving user comfort. Furthermore, the seatbelt can be secured as close to the passenger's thighs as possible, minimizing the passenger's forward displacement during braking or an accident, allowing the seatbelt to generate restraining force promptly, enabling the airbag to be deployed promptly in a serious accident, and improving safety performance.

[0045] like Figure 3As shown, the locking member includes a gear 220 and a rack 230 that are arranged inside the connecting portion 200 and meshed with each other, and a plurality of locking pins 240 connected to the rack 230. The number of the locking pins 240 is the same as the number of the plug-in holes 210 and can be inserted into the locking hole 121. By providing a plurality of plug-in holes 210 on the connecting portion 200 into which the plug-in end 120 can be inserted, the plug-in end 120 can select the plug-in hole 210 at a suitable position for connection and fixation according to the body shape of the passenger, so that the connection position of the seat belt connection device 100 and the connecting portion 200 can be adjusted. Therefore, the gear locking seat belt connection mechanism of the present application can be suitable for passengers of different body shapes, thereby improving the comfort of use. By providing a meshing gear 220 and a rack 230 inside the connecting portion 200, by rotating The gear 220 drives the rack 230 to move left and right, and then drives the locking pin 240 connected to the rack 230 to move, so that the locking pin 240 can be inserted into the lock hole 121 on the plug end 120, and the plug end 120 plugged into the plug hole 210 is locked, thereby fixing the safety belt connection device 100 on the connection part 200. This not only can achieve a stable connection between the safety belt connection device 100 and the connection part 200 on the seat or safety cushion, but also is simple to operate and easy to disassemble.

[0046] In the present application, the installation height of the locking pin 240 inside the connecting part 200 is the same as the height of the locking hole 121 on the plug-in end 120 inserted into the plug-in hole 210, and the size of the locking hole 121 is larger (1-5 mm larger) than the cross-sectional size of the locking pin 240, so that when the gear 220 is rotated and the rack 230 drives the locking pin 240 to move, the locking pin 240 can be easily inserted into the locking hole 121, fixing the plug-in end 120 inserted into the plug-in hole 210, thereby fixing the safety belt connection device 100 to the connecting part 200.

[0047] The movement direction of the rack 230 is parallel to the axis of the lock hole 121 on the plug end 120 plugged into the plug hole 210. Figure 2 and Figure 3 As shown, the axis direction of the lock hole 121 on the plug end 120 plugged into the plug hole 210 is perpendicular to the direction of the plug hole 210, and the direction of the plug hole 210 is parallel to the Figure 2 The left and right side walls of the middle connecting part 200, when the gear 220 is rotated, the movement direction of the rack 230 is perpendicular to the left and right side walls of the connecting part 200, and the gear 220 drives the rack 230 to move in the left and right directions, thereby causing the locking pin 240 to also move in the left and right directions. During the movement, the locking pin 240 can be inserted into the lock hole 121.

[0048] In some embodiments, one end of the rack 230 is engaged with the gear 220, and the other end is fixed with a connecting rod 242 that connects all the locking pins 240. Figure 3 and Figure 5 As shown, in the present application, the number of locking pins 240 is the same as the number of plug-in holes 210, and the installation position of the locking pin 240 corresponds to the plug-in hole 210, so that when the plug-in end 120 is plugged into the plug-in hole 210, the locking pin 240 can be inserted into the lock hole 121 to fix the seat belt connection device 100.

[0049] like Figure 3 As shown, in some embodiments, the connecting portion 200 is provided with multiple locking pins 240, which are connected by a connecting rod 242. The connecting rod 242 is fixed to the end of the rack 230. When the gear 220 drives the rack 230 to move left and right, the rack 230 can simultaneously drive the multiple locking pins 240 to move via the connecting rod 242. Therefore, no matter where the plug end 120 of the seat belt connection device 100 is inserted into the plug hole 210 on the connecting portion 200, the locking pin 240 at the corresponding position can be inserted into the lock hole 121 to secure the plug end 120. Therefore, the present application can drive the movement of multiple locking pins 240 by simply engaging a set of gears 220 and the rack 230, which not only saves installation space and reduces the volume of the connecting portion 200, but also significantly reduces production costs.

[0050] In some embodiments, as Figure 3 and Figure 4 As shown, a mounting hole 241 is provided in the middle of the locking pin 240, and the connecting rod 242 is installed in the mounting hole 241. One end of the locking pin 240 can be inserted into the lock hole 121 as the rack 230 moves to fix the safety belt connection device 100. The other end of the locking pin 240 is connected to the inner wall of the connecting part 200 through a spring 250. One end of the spring 250 is installed at the end of the locking pin 240, and the other end is fixed to the right side wall of the connecting part 200. The elastic force of the spring 250 keeps the locking pin 240 in place. Figure 4 The locking position in the middle improves the reliability of locking the safety belt connection device 100.

[0051] In some embodiments, as Figure 4 As shown, the length of the mounting hole 241 in the direction of movement of the locking pin 240 is greater than the diameter of the connecting rod 242 (for example, 2-3 times), so that the connecting rod 242 can move within a preset range relative to the locking pin 240, and the rack 230 carries the connecting rod 242 to move to the position where the locking pin 240 is located. Figure 4When the locking pin 240 is in the position described above (connecting rod 242 moves to the rightmost end of mounting hole 241), locking pin 240 can enter plug hole 210 under the elastic force of spring 250, locking the plug end 120 located in plug hole 210; at this time, gear 220 can be further rotated to make connecting rod 242 move to the leftmost end of mounting hole 241. At this time, the position of locking pin 240 is doubly locked by connecting rod 242 and spring 250. Even if external force accidentally fluctuates gear 220 and causes connecting rod 242 to move a short distance to the right, locking pin 240 will not fall out of lock hole 121 due to the elastic force of spring 250, thus playing a double insurance role.

[0052] In some embodiments, as Figure 3 and Figure 6 As shown, the gear 220 is connected to a gear shaft 260, one end of the gear shaft 260 is fixedly connected to the gear 220, and the other end passes through the front wall of the connecting portion 200 and is installed with a rotating handle 261. Figure 3 and Figure 7 As shown, a threaded hole 262 is provided at one end of the gear shaft 260 where it is connected to the rotating handle 261. A through hole having a diameter larger than that of the gear shaft 260 is provided on the front wall of the connecting portion 200. After the gear shaft 260 passes through the through hole in the front wall of the connecting portion 200, the rotating handle 261 is threadedly connected to the threaded hole 262 of the gear shaft 260 using a bolt or other connecting member. By providing the rotating handle 261 at the end of the gear shaft 260 extending out of the connecting portion 200, a passenger can rotate the rotating handle 261 to rotate the gear 220, thereby moving the rack 230 and the locking pin 240, thereby achieving the fixing and removal of the seat belt connection device 100 and facilitating operation for the passenger.

[0053] Specifically, when the seat belt connection device 100 needs to be fixed on the connecting part 200, first, the plug end 120 is inserted into the plug hole 210 at an appropriate position on the connecting part 200 according to the passenger's body shape, and then the rotating handle 261 is turned to rotate the gear 220 clockwise. The gear 220 will drive the rack 230 to move to the left, and then drive all the locking pins 240 through the connecting rod 242 to stretch the spring 250 and move to the left. As the gear 220 rotates, the locking pin 240 corresponding to the position of the lock hole 121 is inserted into the lock hole 121, thereby realizing the connection and fixation between the seat belt connection device 100 and the connecting part 200. When the safety belt connection device 100 needs to be removed from the connecting part 200, the rotating handle 261 is turned counterclockwise to rotate the gear 220. The gear 220 drives the rack 230 to move to the right, and then drives all the locking pins 240 through the connecting rod 242 to compress the spring 250 and move to the right. As the gear 220 rotates, the locking pin 240 is pulled out of the lock hole 121, and then the plug end 120 is taken out of the plug hole 210, and the safety belt connection device 100 can be removed from the connecting part 200.

[0054] In some embodiments, as Figure 4 and Figure 5 As shown, the connecting portion 200 is formed by splicing an upper connecting portion 270 and a lower connecting portion 280, and the locking devices such as the locking pin 240 and the rack 230 are installed at the joint between the upper connecting portion 270 and the lower connecting portion 280. By configuring the connecting portion 200 as a top-to-bottom splicing structure, the joint between the upper connecting portion 270 and the lower connecting portion 280 provides sufficient space for the installation of the rack 230 and the locking pin 240, while also facilitating the installation and operation of the rack 230, the locking pin 240, and the spring 250.

[0055] In some embodiments, as Figure 1As shown, the plug end 120 can be a rectangular plug piece, and a lock hole 121 is provided on the plug piece. The shape of the lock hole 121 can be circular, oval, triangular or other special shapes; the connecting end 110 includes a fixing part 111 and a movable part 112. The fixing part 111 and the plug end 120 are made and set in an integrated manner. The fixing part 111 and the movable part 112 themselves can be strip-shaped structural parts. The setting direction of the fixing part 111 is perpendicular to the plug end 120. The two ends of the fixing part 111 are respectively provided with ear plates 1 protruding away from the plug end 120. 13. The movable part 112 is fixed to the ear plate 113 by a transverse fastener 114. By providing the ear plate 113, a gap 116 for the free passage of the safety belt is generated between the movable part 112 and the fixed part 111, so that the safety belt connecting device 100 can be freely slidably installed on the safety belt; when the safety belt connecting device 100 needs to be fixed to or removed from the safety belt, the fixed part 111 and the movable part 112 can be disassembled by removing the fasteners 114 at both ends, thereby facilitating the fixing and removal of the safety belt connecting device 100.

[0056] As a preferred option, Figure 1 As shown, a gap 116 is provided between the connecting end 110 and the plug end 120, through which the seat belt can pass, so that the seat belt connecting device 100 can be moved on the seat belt. This not only facilitates connecting the seat belt connecting device 100 to the connecting portion 200, but also allows the seat belt connecting device 100 to be adjusted to a comfortable position for the passenger on the seat belt, thereby further improving the passenger's comfort.

[0057] When the seat belt connection device 100 of the present application is not in use, the seat belt connection device 100 remains connected to the seat belt. When in use, after the passenger sits on the seat or safety cushion, the plug end 120 of the seat belt connection device 100 is fixed to the connecting part 200, and the plug hole 210 is selected at a suitable position according to the passenger's abdominal size and body shape to ensure the passenger's comfort. After use, the plug end 120 can be removed from the connecting part 200.

[0058] As a preferred embodiment, the connecting end 110, the plug end 120, the lock hole 121, the gap 116 and the fastener 114 of the seat belt connection device 100, as well as the gear 220, the rack 230, the locking pin 240, the connecting rod 242, the spring 250, the gear shaft 260, the rotating handle 261, the upper connecting part 270 and the lower connecting part 280 of the connecting part 200 are all made of high-strength metal, alloy, high-strength carbon fiber, high-strength plastic, high-strength nylon, high-strength fiberglass, high-strength ceramic or polymer material, which can improve the structural strength of the gear locking seat belt connection mechanism of the present application and ensure the safety of passengers.

[0059] As a preferred embodiment, the connecting portion 200 is installed in the middle of the seat or safety cushion, between the legs, and / or at the two front corners of the seat or safety cushion. When a passenger is wearing pants, the seat belt, fastened in accordance with existing technical specifications, can be secured to the middle of the seat or safety cushion, between the legs, near the base of the thighs, or at the two front corners of the seat or safety cushion using the gear-locking seat belt connection mechanism. The seat belt knot located at the abdomen is then secured to the middle of the seat or safety cushion, between the legs, near the base of the thighs, or at the two front corners of the seat or safety cushion. This transfers the pressure of the seat belt on the passenger's abdomen to the thighs, preventing the belt from contracting and compressing the passenger's abdomen and causing discomfort in the event of an accident or braking. When a passenger is wearing a skirt, since it is inconvenient to secure the seat belt in the middle of the seat or safety cushion, between the legs, near the base of the thighs, the seat belt can be secured to the seat or safety cushion, between the legs, near the edge of the cushion, or at the two front corners of the seat or safety cushion, to transfer the pressure of the seat belt on the passenger's abdomen to the thighs.

[0060] Example 2:

[0061] like Figure 9 As shown, the locking members are several safety buckle female buckles 290 disposed within the connecting portion 200. The plug-in end 120 can be inserted into the connecting portion 200 and cooperate with the safety buckle female buckles 290 to form a lock. The safety buckle female buckles 290 are fixed within the cavity of the connecting portion 200 by welding, riveting, bolts, or screws. During use, the safety buckle female buckles 290 can be selected in an appropriate position according to the passenger's abdominal size and body shape, and the seat belt can be restrained as close to the passenger's thigh as possible. This minimizes the passenger's forward displacement during braking or an accident, allowing the seat belt to generate restraining force in a timely manner, and can trigger the airbag to deploy in a serious accident, thereby improving the safety of the safety seat cushion and the comfort and convenience of the passenger.

[0062] The rest of this embodiment is the same as that of the first embodiment.

[0063] Example 3:

[0064] This embodiment is the same as the first embodiment, except that the structure of the connection end 110 of the safety belt connection device 100 is different. Figure 10As shown, the connecting end 110 includes a fixing part 111 and a movable part 112. The fixing part 111 and the plug-in end 120 are integrally manufactured and arranged. The fixing part 111 and the movable part 112 themselves can be bar-shaped structural parts. The setting direction of the fixing part 111 is perpendicular to the plug-in end 120. Ear plates 113 protruding away from the plug-in end 120 are respectively provided at both ends of the fixing part 111. The movable part 112 is fixed to the ear plates 113 by longitudinal bolts 115. By setting the ear plates 113, a gap 116 for the safety belt to pass freely is generated between the movable part 112 and the fixing part 111, so that the safety belt connecting device 100 can be freely slidably installed on the safety belt.

[0065] Example 4:

[0066] This embodiment is the same as the first embodiment, except that the structure of the connection end 110 of the safety belt connection device 100 is different. Figure 11 As shown, the connecting end 110 includes a fixed part 111 and a movable part 112. The fixed part 111 and the plug-in end 120 are integrally manufactured and arranged. The fixed part 111 and the movable part 112 themselves can be strip-shaped structural parts. The setting direction of the fixed part 111 is perpendicular to the plug-in end 120. Single ear holes 117 are respectively provided at both ends of the fixed part 111, and double ear holes 118 are respectively provided at both ends of the movable part 112. The double ear holes 118 at one end of the movable part 112 are installed on the single ear hole 117 at one end of the fixed part 111 through a rotating shaft 119, and the double ear holes 118 at the other end of the movable part 112 are detachably connected to the single ear hole 117 at the other end of the fixed part 111 through a fastener 114. A gap 116 for the safety belt to pass freely is generated between the movable part 112 and the fixed part 111, so that the safety belt connecting device 100 can be freely slidably installed on the safety belt.
