Description
Technical Field
[0001] The utility model relates to the technical field of latch assembly, in particular to a latch assembly device based on elastic push assembly. Background Art
[0002] The latch assembly device is a device used for the latch assembly in the automotive seat belt. Specifically, the latch assembly device usually includes components such as a latch shaft, a bearing, and a positioning sleeve. The latch is assembled on the latch shaft by interference fit and positioned by the positioning sleeve, which realizes the precise grasping and efficient installation of the latch assembly.
[0003] The latch assembly device cannot avoid the displacement and jamming of the latch, resulting in a large deviation in the assembly position and a reduction in product quality; nor can it fix the remaining latches, often pushing excessive latches, causing assembly errors and equipment failures, increasing the probability of misoperation, and weakening the overall structural stability. Summary of the Utility Model
[0004] The utility model discloses a latch assembly device based on elastic push assembly, aiming to solve the technical problems that the latch assembly device cannot avoid the displacement and jamming of the latch, resulting in large assembly deviation and reduced quality, and also cannot fix the remaining latches, often pushing excessive latches to cause assembly errors and equipment failures, increasing the probability of misoperation, and weakening the structural stability.
[0005] To achieve the above object, the utility model adopts the following technical scheme: A latch assembly device based on elastic push assembly, including a base table. Above the base table is provided a material cylinder, on which a locking position assembly is arranged. The locking position assembly includes a motor frame, the top of the motor frame is fixedly connected to the outer side of the material cylinder, and the front end of the motor frame is fixedly connected to a bidirectional motor. The power output shaft of the bidirectional motor is connected to a bidirectional rotating lead screw through a coupling. The outer side center position of the bidirectional rotating lead screw is movably connected to a central positioning member, one end of the central positioning member is fixedly connected to the inner side of the material cylinder, and an auxiliary sliding rod is fixedly connected to the inner side of the material cylinder. The auxiliary sliding rod is located in front of the bidirectional rotating lead screw. Symmetrical sliding plates are movably connected to the outer sides of both the auxiliary sliding rod and the bidirectional rotating lead screw. Compression springs are fixedly connected to the opposite sides of the sliding plates, and flexible plates are fixedly connected to the front ends of the compression springs.
[0006] By providing a bottom platform, a material cylinder, and a locking component, during the elastic pushing process of latch assembly, the bidirectional motor is powered on and rotates, driving the bidirectional rotating screw rod to start rotating. Since the bidirectional rotating screw rod has a bidirectional thread structure, it will drive the sliding plates on both sides to move relative to the screw rod and the auxiliary slide rod (i.e., move closer to the middle) during rotation. During the movement of the sliding plates, the compression springs and flexible plates connected to them are driven to move together. As the sliding plates gradually approach, the compression springs start to be compressed, and the flexible plates gradually approach the center position inside the material cylinder. When the flexible plates contact both sides of the latch, under the elastic action of the compression springs, the flexible plates generate a clamping force on the latch, and through the positioning effect of the central positioning component, the latch located in the middle is stably clamped at the center position inside the material cylinder. At the same time when the flexible plates clamp the latch, due to the inward pressure and positional relationship, it will form a blocking and fixing effect on the latch, keeping the remaining latches relatively stable inside the material cylinder, preventing too many latches from being pushed out together when pushing the current latch, achieving the clamping and fixing of the latch, avoiding position deviation. During the process, the locking component can prevent the latch from shifting and getting stuck, ensure that the latch is in the accurate position during assembly, improve the assembly accuracy, guarantee the product quality, and at the same time be able to fix the remaining latches, prevent pushing too many latches, prevent assembly errors or equipment failures caused by pushing too many latches at one time, reduce the possibility of misoperation, and further enhance the stability of the overall structure.
[0007] In a preferred solution, a support seat is fixedly connected to the top end of the bottom platform, the top end of the support seat is fixedly connected to the bottom end of the material cylinder, and rectangular holes are opened on both sides of the material cylinder close to the bidirectional motor. A push plate is movably connected inside the rectangular hole on one side close to the material cylinder. The push plate is located below the locking component. Diagonal plates are fixedly connected to both sides inside the material cylinder. The diagonal plates are located below the push plate. One end of the push plate away from the material cylinder is fixedly connected to a connecting plate. A telescopic cylinder is fixedly connected to the top end of the connecting plate, and a support frame is fixedly connected to the outside of the telescopic cylinder. The front end of the support frame is fixedly connected to the rear end of the material cylinder. A symmetric seat is fixedly connected to the top end of the bottom platform. An auxiliary platform is fixedly connected to the top end of the symmetric seat, and a sliding seat is fixedly connected to the front end of the auxiliary platform. A spring piece is movably connected to the front end of the sliding seat.
[0008] In a preferred embodiment, a pushing platform is provided at the front end of the auxiliary platform. A sliding track is movably connected to one side of the pushing platform close to the material cylinder, and the outer side of the sliding track is fixedly connected to the outer side of the material cylinder. A paddle is movably connected to the front end of the pushing platform. A hole is formed in the side of the pushing platform close to the rectangular hole on the material cylinder, and a pushing plate is movably connected inside the hole. An observation window is fixedly connected to the top of the pushing platform. Symmetrical three-way valves are fixedly connected to the outer side of the telescopic cylinder, and the three-way valves are all in front of the support frame. An air pipe is fixedly connected between the front ends of the three-way valves at the frontmost position. A round hole is formed at the bottom end of the pushing platform, and the inside of the round hole is movably connected to the outer side of the air pipe. The end of the air pipe away from the three-way valve is fixedly connected to a flipping cylinder, and the top of the flipping cylinder is fixedly connected to the paddle. A shunt pipe is fixedly connected to the outer side of the air pipe, and the shunt pipe is movably connected inside the pushing platform. The top of the shunt pipe is fixedly connected to a pushing cylinder, and the top of the pushing cylinder is fixedly connected to the front end of the auxiliary platform.
[0009] By providing a symmetrical seat, an auxiliary platform, a sliding seat, a spring piece, a pushing platform, a sliding track, a paddle, an observation window, an air pipe and a three-way valve, when the device operates, the pushing cylinder starts, and the power is transmitted through the shunt pipe and the air pipe. The pushing platform slides along the sliding track towards the auxiliary platform until they come into contact. After the pushing platform contacts the auxiliary platform, the telescopic cylinder acts, and drives the pushing plate to slide in the rectangular hole of the material cylinder through the connecting plate. The pushing plate pushes the latch to move until the latch reaches the position above the spring piece and below the paddle. The valve port in the three-way valve communicating with the air pipe is opened, and the gas enters the flipping cylinder through the air pipe to make it operate. The flipping cylinder drives the paddle to flip downwards, the paddle presses down the latch, the latch presses down the spring piece, the spring piece deforms and loses the support for the latch, and the latch deflects downwards under the action of gravity, changing from a horizontal state to a vertical state during the movement and finally falling downwards.

And a support frame 16 is connected to the outer side of the telescopic cylinder 10 by bolts. The front end of the support frame 16 is connected to the rear end of the material cylinder 9 by bolts.
[0021] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the top of the base 1 is connected to a symmetrical seat 3 by bolts, the top of the symmetrical seat 3 is connected to an auxiliary platform 5 by bolts, and the front end of the auxiliary platform 5 is connected to a sliding seat 15 by bolts, and the front end of the sliding seat 15 is connected to a spring piece 18 by rotation, and a pushing platform 4 is provided at the front end of the auxiliary platform 5, and the side of the pushing platform 4 close to the material barrel 9 is connected to a sliding track 6 by sliding, and the outer side of the sliding track 6 is connected to the outer side of the material barrel 9 by bolts, and the front end of the pushing platform 4 is connected to a paddle 17 by rotation, and a hole is opened on the side of the pushing platform 4 close to the rectangular hole on the material barrel 9, and the pushing plate 7 is located inside the hole and connected by sliding, and the top of the pushing platform 4 is connected to an observation window 14 by bolts, and the extension The outside of the compression cylinder 10 is connected with a symmetrical three-way valve 13 by bolts, and the three-way valves 13 are all located in front of the support frame 16. The front end of the three-way valve 13 located in the front is connected with the air pipe 11 by bolts. A circular hole is opened at the bottom of the pushing platform 4, and the inside of the circular hole is connected to the outside of the air pipe 11 by sliding. The end of the air pipe 11 away from the three-way valve 13 is connected with a flip cylinder 21 by bolts, and the top of the flip cylinder 21 is connected to the paddle 17 by bolts. The outside of the air pipe 11 is connected with a shunt pipe 22 by bolts. The shunt pipe 22 is located inside the pushing platform 4 and is connected by sliding. The top of the shunt pipe 22 is connected with the pushing cylinder 20 by bolts, and the top of the pushing cylinder 20 is connected to the front end of the auxiliary platform 5 by bolts.
[0022] Working principle: When the device is operating, the driving cylinder 20 is activated, and power is transmitted through the shunt pipe 22 and the air pipe 11, pushing the pushing platform 4 to slide along the sliding track 6 towards the auxiliary platform 5 until they come into contact. After the pushing platform 4 contacts the auxiliary platform 5, the telescopic cylinder 10 acts, driving the pushing plate 7 to slide within the rectangular hole of the material cylinder 9 through the connecting plate 8. The pushing plate 7 pushes the latch to move until the latch reaches a position above the elastic piece 18 and below the dial 17. The valve port in the three-way valve 13 that is connected to the air pipe 11 opens, and gas enters the flipping cylinder 21 through the air pipe 11 to make it operate. The flipping cylinder 21 drives the dial 17 to flip downwards. The dial 17 presses down on the latch, and the latch presses down on the elastic piece 18. The elastic piece 18 deforms and loses its support for the latch. The latch deflects downwards under the action of gravity and changes from a horizontal state to a vertical state during the movement, and finally drops downwards; during the elastic pushing process of the latch assembly, the bidirectional motor 1202 is energized and operates, driving the bidirectional rotating lead screw 1203 to start rotating. Since the bidirectional rotating lead screw 1203 has a bidirectional thread structure, it will drive the sliding plates 1207 on both sides to move relative to each other (i.e., move closer to the middle) along the lead screw and the auxiliary slide rod 1205 during rotation. During the movement of the sliding plates 1207, the compression springs 1208 and the flexible plates 1206 connected to them are driven to move together. As the sliding plates 1207 gradually approach, the compression springs 1208 start to be compressed, and the flexible plates 1206 gradually approach the center position inside the material cylinder 9. When the flexible plates 1206 contact both sides of the latch, under the elastic action of the compression springs 1208, the flexible plates 1206 generate a clamping force on the latch, and the latch located in the middle is stably clamped at the center position inside the material cylinder 9 through the positioning effect of the central positioning member 1204. While the flexible plates 1206 clamp the latch, due to the inward pressure and positional relationship, a blocking and fixing effect will be formed on the latch, keeping the remaining latches relatively stable inside the material cylinder 9 and preventing too many latches from being pushed out together when pushing the current latch, realizing the clamping and fixing of the latch and avoiding the deviation of its position.

The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution.
