Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a backrest unlocking assembly. Background Art

[0002] The backrest unlocking assembly is a device used to lock and unlock the seat back. The main function of the seat back unlocking assembly is to control the locking and unlocking status of the seat back. When the seat back angle needs to be adjusted, the lock hook is disengaged from the locked state by operating the relevant components in the unlocking assembly, thereby allowing the backrest to be adjusted in angle. After the adjustment is completed, the lock hook is re-locked by pushing the backrest backward or operating the corresponding locking mechanism to ensure the stability and safety of the seat back. The backrest unlocking assembly is widely used in various types of car seats, including passenger cars, commercial vehicles, etc.

[0003] A backrest strap unlocking mechanism with Chinese utility model announcement number CN210437050U includes a cable mounting crankshaft, a zipper assembly, a handle drive assembly and a strap drive assembly. The utility model discloses a backrest strap unlocking mechanism, which integrates shoulder handle unlocking and rear strap unlocking in the same structure through the handle drive assembly and the strap drive assembly respectively connected to the cable mounting crankshaft. The handle does not move when the strap is unlocked, and the operation is relatively independent. A common zipper drives the recliner to unlock, which is low in cost.

[0004] At least the following problems exist in this technology: the seatback strap unlocking mechanism drives some components of the zipper assembly to move when the zipper installation crankshaft rotates, and separates the zipper assembly from the handle drive assembly through the movement of some components of the zipper assembly, thereby achieving control of a single structure. However, during use, the zipper assembly and the handle assembly are in a rotationally connected state, so there will be a certain amount of jamming after they are separated from the handle drive and then installed, and the subsequent connection will not be tight. Therefore, a seatback unlocking assembly is now proposed. Utility Model Content

The unlocking assembly 2 includes a bearing shell 201, and a bearing port 202 is opened on the top of the bearing shell 201. The outer side of the bearing shell 201 located at the bottom of the bearing port 202 is provided with an installation port 203. The elastic clamp 103 is located at the installation port 203 and has an installation port matching the installation port 203. The mounting groove 4 is formed by installing the supporting shell 201 of the unlocking assembly 2 inside the base assembly 1, and the supporting shell 201 is installed by clamping through the elastic clamp 103 at the base 101. This is not only convenient and quick during the installation process, but also makes the connection between the two more precise. Moreover, since the two remain in a clamped state, they will not be separated during the unlocking and locking process. The mounting groove 4 is formed at the elastic clamp 103, and an elastic clamp plate 5 is fixedly installed above the mounting groove 4. The mounting groove 4 can facilitate the downward clamping effect of the mounting port 203 and the overall supporting shell 201.

[0032] Reference Figure 1 and Figure 3The connecting component 3 includes a rotating shaft seat 6, and a rotating shaft 7 is rotatably installed inside the rotating shaft seat 6. The rotating shaft 7 can realize the connection between the base 101 and the bearing shell 201, and the rotating shaft 7 realizes the strengthening fixation and driving effect between the two. One end of the rotating shaft 7 is rotatably installed on the inner wall of the base 101, and the rotating shaft 7 is provided with a torsion spring 14 at the inner wall of the base 101. The torsion spring 14 is provided on the inner wall of the base 101. The other end of the rotating shaft 7 passes through the base 101, and the other end of the rotating shaft 7 is connected with a handle 8. The handle 8 can realize the rotation effect of the rotating shaft 7, and the torsion spring 14 realizes the reset effect of the handle 8 after the rotating shaft 7 is rotated. The rotating shaft 7 is located on one side of the rotating shaft seat 6 and is elastically plugged with a rotating plate 9, and the base 101 is located at the rotating A rotating groove matching the rotating plate 9 is provided at the plate 9, and a locking mechanism is fixedly connected to the other end of the rotating plate 9. The locking mechanism is the locking mechanism used in real life and is a prior art, so it is not described in detail. The rotating plate 9 can be realized after the rotating shaft 7 is rotated, and its rotating plate 9 can be synchronously operated by connecting it to the locking mechanism. A connecting seat 10 is fixedly installed under the base 101, and a through hole is provided in the middle of the connecting seat 10.

[0033] The implementation principle of the utility model is as follows: first, during the installation process, the bearing shell 201 is pressed against the inside of the base 101. During the process of pressing and installing the bearing shell 201, the two sides of the bearing shell 201 will squeeze the elastic card plate 5 at the elastic card member 103 and move down along the elastic card plate 5. When the bearing shell 201 moves to a certain position, the elastic card plate 5 at the installation groove 4 will realize the clamping and fixing effect of the bearing shell 201. This is not only convenient and quick during the installation process, but also makes the connection between the two more precise. Moreover, since the two maintain a clamping state, they will not be separated during the unlocking and locking process. At this time, a rotating shaft 7 is passed through the base 101 and the rotating shaft seat 6 and is rotatably installed on the base 101. When the rotating shaft 7 is installed on the inner wall of the base 101, one side of the rotating shaft 7 will be inserted into the torsion spring 14 and realize The connection with the torsion spring 14 enables the torsion spring 14 to be driven after the subsequent rotation of the rotating shaft 7. Then, when the rotating shaft 7 is fixedly installed, the rotating plate 9 is elastically inserted into the outer side of the rotating shaft 7 at the rotating groove of the base 101, so that the rotating shaft 7 and the rotating plate 9 are fixedly connected. Then, the side of the rotating plate 9 away from the rotating shaft 7 is connected to the required and matching locking mechanism, so that the unlocking assembly 2 can achieve unlocking and locking effects during operation. Then, the handle 8 can be threadedly installed on the side of the rotating shaft 7 away from the base 101, and then the overall base 101 and the unlocking assembly 2 inside the base 101 can be installed at the required installation position through the connecting seat 10. When the backrest is unlocked, the handle 8 is rotated to make the handle 8 drive the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rotating plate 9 to rotate at the rotating groove when rotating, so that the locking mechanism below is pulled by the rotation of the rotating plate 9 to unlock the backrest.
