[0039] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments, but can be implemented in various variations. The purpose of providing these embodiments is to better disclose the present invention and enable those skilled in the art to better understand the scope of the present invention.

[0040] The up and down direction terms used herein respectively represent Figure 4a the up and down directions in Figure 4a and the inner and outer directions in Figure 4a respectively represent the left and right directions in

[0041] Figure 2a and Figure 2b respectively show an assembled perspective view and an exploded perspective view of a buckle device according to an embodiment of the present invention, and Figure 2c shows a perspective view of the buckle device with the connecting member removed according to an embodiment of the present invention.

[0042] As Figures 2a to 2c shown, the buckle device 1 includes a buckle 10, a connecting member 20, and a mounting member 30. The buckle 10 includes a base frame 110, and the base frame 110 has a mounting portion. The mounting portion is provided at one end of the base frame 110 and is configured as a through hole 111. For example, the number of through holes 111 is two. The mounting portion is fixed to the connecting member 20, and the connecting member 20 is fixed to the vehicle, so that the buckle 10 is fixed to the vehicle via the connecting member 20. The connecting member 20 is in the shape of a long strip plate 320. In the embodiment, the mounting member 30 includes a rivet 310 and a plate 320. The connecting member 20 can be clamped between the base frame 110 and the plate 320 and is connected to the mounting portion by a pair of rivets 310 inserted into the through hole 111. The buckle device 1 is configured such that in the assembled state of the buckle 10, the mounting member 30 can install the connecting member 20 to the mounting portion along the mounting direction without obstruction.

[0043] In the buckle device of this embodiment, when assembling the buckle device, the various components of the buckle can be assembled first, and then the connecting member can be installed to the mounting portion through the mounting member. That is, the connecting member is installed after the buckle is assembled. Thus, the problem of inconvenience in subsequent assembly processes caused by installing the connecting member first is avoided, and it is beneficial to construct an efficient automated assembly production line for assembling the buckle device. In addition, the number of workers on the production line can also be reduced, the assembly efficiency can be improved, and the assembly cost can be reduced.

[0044] Figure 3a and Figure 3b respectively show an assembled perspective view and an exploded perspective view of the buckle according to an embodiment of the present invention, and Figure 4a and Figure 4bCross-sectional views of a buckle in a locked position and in an unlocked position according to an embodiment of the present invention are shown respectively.

[0045] As Figures 3a to 4b shown, in addition to the chassis 110, the buckle 10 further includes a locking member 120, a pusher assembly 130, a sliding assembly 140, and an operating member 150. The chassis 110 is a base element to which the locking member 120, the pusher assembly 130, the sliding assembly 140, and the operating member 150 are mounted. The chassis 110 includes two side walls 112 and a bottom plate 113, and has a generally U-shaped configuration. The locking member 120 is rotatably supported on the chassis 110 between a locked position and an unlocked position. In the locked position, the locking member 120 engages with the locking tongue 2, and in the unlocked position, the locking member 120 disengages from the locking tongue 2. The pusher assembly 130 is movably supported on the chassis 110. The pusher assembly 130 can push the locking member 120 from the unlocked position to the locked position under the push of the locking tongue 2, and can push the locking tongue 2 out of the buckle 10 when the locking member 120 disengages from the locking tongue 2. The sliding assembly 140 is slidably supported on the locking member 120, and can prevent the locking member 120 from moving toward the unlocked position when the locking member 120 is in the locked position. The operating member 150 is movably supported on the chassis 110. The pusher assembly 130 is provided with a biasing portion 1335. The operating member 150 can be operated to push the sliding assembly 140 to the biasing portion 1335 when the locking member 120 is in the locked position, and the biasing portion 1335 biases the sliding assembly 140 to allow the sliding assembly 140 to further move, so as to drive the locking member 120 to move to the unlocked position.

[0046] Figures 5a to 6c Schematic views of some components of a buckle in a locked position or an unlocked position according to an embodiment of the present invention are shown respectively.

[0047] As Figures 5a to 6c shown and referring also to Figure 3b , the locking member 120 has a main body portion 121, a locking portion 122, and a rotation shaft 123. The locking portion 122 and the rotation shaft 123 are respectively disposed at the front end and the rear end of the main body portion 121 in the longitudinal direction (front-rear direction) of the buckle 10. The middle portion of the main body portion 121 is open to form a spring seat in which a pusher member spring 132 (described in detail below) is placed. A protrusion 124 is provided at the rear end of the spring seat, and the pusher member spring 132 is sleeved on the protrusion 124. The protrusion 124 extends forward and downward from the rear end of the spring seat. Support grooves 114 are formed on the two side walls 112 of the chassis 110, and the rotation shaft 123 is rotatably supported in the support grooves 114. The locking portion 122 can engage with the locking tongue 2 (see Figure 4b)Engagement, when engaged, the locking portion 122 can be inserted into the locking groove 20 of the locking tongue 2.

[0048] The ejector assembly 130 includes an ejector member 131 and an ejector member spring 132. The ejector member 131 includes an ejector body 133 and a sliding protrusion 1333. The front side of the ejector body 133 has a contact end 1331 (see Figure 4a ) for contacting the rear end of the locking tongue 2. The rear side end of the ejector body 133 has a receiving groove 1332 for receiving the front end portion of the ejector member spring 132. The sliding protrusion 1333 protrudes from the left and right sides of the ejector body 133. An ejector slot 115 is formed on the chassis 110, and the ejector slot 115 is formed in the middle of the lower ends of the two side walls 112 along the front-rear direction of the chassis 110, and the sliding protrusion 1333 can be inserted into the ejector slot 115 (see Figure 3b ). Thus, the ejector member 131 is movably supported on the chassis 110.

[0049] The ejector member spring 132 is disposed in a contracted manner between the locking member 120 and the ejector member 131, and as described above, the front end of the ejector member spring 132 is inserted into the receiving groove 1332 of the ejector member 131, and the rear end thereof is sleeved on the protrusion 124 of the locking member 120. Therefore, the ejector member spring 132 applies a force to the locking member 120 in the counterclockwise direction, causing the locking member 120 to move to the locking position, and the ejector member spring 132 applies a force to the ejector member 131 in the direction of the locking tongue 2.

[0050] The sliding assembly 140 includes a sliding member 141, a sliding member spring 142, and a locking bar 143. The sliding member 141 has a protrusion 1411 extending along the length direction of the buckle 10, and a corresponding hole 123a is provided on the rotation shaft 123 of the locking member 120 (see Figure 3b ). The protrusion 1411 passes through the hole 123a on the locking member 120 and can slide along the hole 123a, so that the sliding member 141 is slidably supported on the locking member 120. The sliding member spring 142 is fitted on the protrusion 1411 and is disposed in a contracted manner between the sliding member 141 and the locking member 120. Therefore, the sliding member spring 142 applies a force to the locking member 120 in the clockwise direction and applies a force to the sliding member 141 in the direction of the locking tongue 2.

[0051] In an embodiment, the sliding member 141 includes two protrusions 1411, and the two protrusions 1411 are respectively located at both ends of the sliding member 141 in the width direction (left-right direction) of the buckle 10. The sliding member springs 142 are respectively fitted on the corresponding protrusions 1411.

[0052] Figure 7aAnd Figure 7b FIG. Figure 7b shows cross-sectional views of partial components of a buckle according to an embodiment of the present invention in a locked position and an unlocked position, respectively. Figure 8 FIG. Figure 8 shows a perspective view of a sliding member and an ejector member assembled together according to an embodiment of the present invention.

[0053] As Figures 7a to 8 shown, a guide groove 1412 is provided on the sliding member 141. Guide rail portions 1211 for guiding the sliding member 141 are respectively provided at the left and right side ends of the main body portion 121 of the locking member 120. The guide groove 1412 can be engaged with the guide rail portions 1211 so that the sliding member 141 can slide relative to the locking member 120.

[0054] Engaging grooves 116 are respectively formed on two side walls 112 of the chassis 110. The locking bar 143 is supported on the engaging grooves 116 and protrudes outward from the two side walls 112 (see below Figure 12 ). On each side wall 112, the engaging groove 116 includes a first groove 1161 extending along the length direction of the buckle 10 and a second groove 1162 extending upward and backward obliquely from the first groove 1161. The first groove 1161 and the second groove 1162 are in communication with each other, and the locking bar 143 can move along the first groove 1161 and the second groove 1162. The locking bar 143 is located between the sliding member 141 and the locking member 120, see Figure 6b and Figure 6c .

[0055] Returning to Figure 3b , the operating member 150 is designed in the form of a button and is installed in front of the chassis 110. Guide holes 117 are formed at the front ends of two side walls 112 of the chassis 110. Guide rib portions 151 of the operating member 150 are inserted into the guide holes 117 and can slide along the length direction of the buckle 10 in the guide holes 117. The locking tongue 2 (see Figure 4b ) can be inserted between the operating member 150 and the bottom plate 113 of the chassis 110. When the locking of the locking tongue 2 is released, the operating member 150 is pressed to release the locking between the locking tongue 2 and the locking member 120. The guide rib portions 151 protrude from the inner surfaces of two side walls 112 of the operating member 150.

[0056] Pressing grooves 152 are recessedly formed on the inner surfaces of two side walls 112 of the operating member 150 and are located behind the guide rib portions 151. Both ends of the locking bar 143 can be inserted into the pressing grooves 152, and when the operating member 150 is pressed backward, the locking bar 143 can move backward together with the operating member 150.

[0057] Figure 9 FIG. Figure 9 shows a perspective view of a chassis installed with an inertia member according to an embodiment of the present invention.

[0058] As Figure 9 shown and referring again to Figure 3b , the buckle device 1 further has an inertia member 160. The inertia member 160 is disposed inside the operating member 150 to prevent the ejector member 131 from being released due to the inertial force generated during the pretensioner operation. The inertia member 160 includes a block 161, a hinge pin 162, and a guide pin 163. A hinge groove 153 is recessed in the inner bottom of the operating member 150 to receive the hinge pin 162. Guide pin grooves 118 are formed on two side walls 112 of the chassis 110 to receive the guide pins 163 extending from the left and right sides of the block 161. The guide pins 163 can rotate within the guide pin grooves 118 and are restricted to the inside of the operating member 150 so that the inertia member 160 does not shift in the left - right direction. Two arms 164 project from the block 161, and each arm 164 presents a claw - shaped end portion. The claw - shaped end portion is adapted to act on the locking bar 143 at the locking position.

[0059] Figure 10 and Figure 11 respectively show perspective views of the ejector member and the sliding member according to an embodiment of the present invention.

[0060] As Figure 10 and Figure 11 shown, the ejector body 133 has a vertical wall 1334 extending upward. The vertical wall 1334 is located at the rear end of the ejector body 133 and is generally located at the middle position of the ejector body 133 in the width direction of the buckle 10. A force - applying portion 1335 formed of an inclined surface is provided on the front side of the vertical wall 1334. A force - receiving portion 1413 formed of an inclined surface is provided on the lower surface of the sliding member 141, and the force - receiving portion 1413 faces the force - applying portion 1335. The force - applying portion 1335 presses the force - receiving portion 1413, thereby applying a force to the sliding member 141 and the locking member 120 in a direction to disengage the locking member 120 from the locking tongue 2.

[0061] Next, the locking and releasing operations of the buckle according to an embodiment of the present invention will be described.

[0062] In the non-locking position of the buckle 10, when the locking tongue 2 is inserted from the front end of the buckle 10, the rear end of the locking tongue 2 abuts against the contact end 1331 of the ejector member 131, thereby pressing the ejector member 131 backward. As the locking tongue 2 is inserted, the front end of the ejector member spring 132 moves backward and contracts. Therefore, the ejector member spring 132 presses the protrusion 124 of the ejector member 131 backward, so that the locking member 120 drives the sliding member 141 to rotate to the locking position (in the counterclockwise direction). Accordingly, the locking portion 122 of the locking member 120 is inserted into the locking groove 20 of the locking tongue 2, and thus the locking member 120 is in the locking position.

[0063] In addition, when the sliding member 141 rotates counterclockwise, it presses against the locking bar 143 to move the locking bar 143, so that the locking bar 143 slides from the second groove 1162 to the front end position of the first groove 1161. The upper surface of the front end of the locking member 120 is pressed against by the locking bar 143. Therefore, since the locking bar 143 holds the locking member 120 in the locking position, the locking member 120 can firmly hold the locking state of the locking tongue 2 and the buckle 10 without allowing the locking tongue 2 to be disengaged from the buckle 10. In addition, since at this time, the sliding member spring 142 applies a forward force to the sliding member 141, the sliding member 141 presses the operating member 150 forward, so that the operating member 150 can be held in the non-operating position.

[0064] In the locking position of the buckle 10, when the operating member 150 is pressed backward, the operating member 150 moves backward. The operating button presses the locking bar 143 backward, and the locking bar 143 presses against the sliding member 141, so that the sliding member 141 moves backward against the elastic force of the sliding member spring 142. The elastic force of the sliding member spring 142 increases as the operating member 150 continues to move backward. Therefore, the locking member 120 rotates to the non-locking position (in the clockwise direction) by means of this elastic force.

[0065] The biased portion 1413 of the sliding member 141 abuts against the biasing portion 1335 of the ejector member 131, thereby squeezing the biasing portion 1335 backward. Specifically, the biased portion 1413 squeezes the biasing portion 1335 in a direction perpendicular to the inclined surface. Therefore, the ejector member 131 moves backward against the elastic force of the spring. When the ejector member 131 starts to move backward, since the ejector member spring 132 becomes shorter, the elastic force of the ejector member spring 132 that squeezes the ejector member 131 gradually increases. By virtue of the reaction force generated by this elastic force, the biasing portion 1335 squeezes the biased portion 1413 in a direction perpendicular to the inclined surface. Therefore, the sliding member 141 has a tendency to move upward. In addition, when the sliding member 141 moves backward, the locking bar 143 disengages from the first groove 1161 and obliquely enters the second groove 1162 upward and backward. Therefore, the locking bar 143 no longer presses against the locking member 120, thereby allowing the locking member 120 to rotate to the unlocked position (in the clockwise direction).

[0066] Compared with the buckle device of the prior art, the buckle device according to an embodiment of the present invention has the same buckle length, and the buckle device according to an embodiment of the present invention can facilitate assembly while maintaining the locking and releasing performance.

[0067] It should be understood that as long as the mounting member can unobstructedly mount the connecting member to the mounting portion in the mounting direction in the assembled state of the buckle, the buckle device is not limited to the above embodiments and may also have other configurations.

[0068] Next, a method for assembling the buckle device 1 according to an embodiment of the present invention will be described.

[0069] Figure 12 A flowchart showing a method for assembling the buckle device 1 according to an embodiment of the present invention is shown. As Figure 12 shown, the method for assembling the buckle device includes the following steps.

[0070] First, obtain each component of the buckle device 1 as described above, that is, the buckle 10, the mounting member 30, and the connecting member 20.

[0071] Next, assemble the buckle 10. The assembly process of the buckle 10 includes: slidably mounting the ejector member 131 on the chassis 110; sleeving the slider member spring 142 on the protruding portion 1411 of the slider member 141; slidably assembling the slider member 141 with the locking member 120; mounting the slider member 141, the slider member spring 142 and the locking member 120 on the chassis 110; mounting the ejector member spring 132 in a contracted manner between the ejector member 131 and the locking member 120; mounting the locking bar 143 on the chassis 110; mounting the inertial member 160 on the chassis 110; and mounting the operating member 150 on the chassis 110.

[0072] Finally, mount the connecting member 20 to the chassis 110 of the buckle 10 by means of the rivets 310 and the plate 320.

[0073] It should be understood that the assembly method of the buckle 10 is not limited to this as long as all the components of the buckle 10 are finally assembled together. For example, the assembly of the slider member 141, the slider member spring 142 and the locking element can be completed before mounting the ejector member 131 on the chassis 110. The step of inserting the locking bar 143 can also be completed before inserting the ejector member spring 132.

[0074] Finally, after assembling the buckle 10, mount the connecting member 20 to the mounting portion of the buckle 10 in the mounting direction by means of the mounting member 30 (i.e., the rivets 310 and the plate 320).

[0075] In the method for assembling the buckle device of this embodiment, when assembling the buckle device, the components of the buckle can be first assembled, and then the connecting member can be mounted to the mounting portion by means of the mounting member. That is to say, the connecting member is mounted after the buckle is assembled. Thereby, the problem of inconvenience in subsequent assembly processes caused by mounting the connecting member first is avoided, and it is beneficial to construct an efficient automated assembly line for assembling the buckle device.

[0076] As described above, although the exemplary embodiments of the present invention have been described with reference to the drawings in the description, the present invention is not limited to the above specific embodiments, and the protection scope of the present invention should be defined by the claims and their equivalent meanings.
