Description

Technical Field

[0001] The utility model relates to a locking mechanism, in particular to a locking mechanism for a vehicle skylight. Background Art

[0002] For safety reasons, many vehicles need to be equipped with sunroofs. Once an accident occurs, people in the car can open the sunroof and escape if the sunroof is not blocked. Most sunroofs are not designed with a locking mechanism, which means that when the sunroof is open, the sunroof itself and the car body can still move freely (swing). In this way, when people are escaping, the sunroof may flip inward due to external force, blocking the escape action and delaying the escape time; and if the person does not escape the vehicle in time after opening the sunroof, the sunroof may get stuck or locked due to impact, vibration or other reasons after it rotates in the opposite direction and re-fastens on the car body, making it impossible for the person to escape.

[0003] Therefore, a method or device capable of solving the above problems is now needed. Summary of the invention

[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and provides a locking mechanism which has a simple structure, ingenious design, reasonable layout and can quickly and reliably lock the position of the sunroof in an open state.

[0005] The technical solution of the utility model is: a locking mechanism for a vehicle sunroof, characterized in that: the locking mechanism comprises a locking frame 1 fixedly connected to the vehicle body and a rotating locking member 2 matched with the end of the locking frame 1,

[0006] The rotary locking member 2 comprises a positioning sleeve 4 fixedly arranged on the skylight 3, and one end of the positioning sleeve 4 facing the inner side of the skylight 3 is provided with four positioning grooves 5 evenly distributed in the circumferential direction, and a rotating shaft 6 is rotatably connected inside the positioning sleeve 4, and a limiting plate 7 is provided at the end of the rotating shaft 6, and the front end is connected to a locking block 9 through a connecting pin 8, and the cross section of the locking block 9 is rectangular, and a driving sleeve 10 is movably sleeved outside the rotating shaft 6, and a limiting pin 11 distributed along its radial direction is connected to the side wall of the driving sleeve 10, and the limiting pin 11 matches the positioning groove 5, and a spring 12 is sleeved outside the rotating shaft 6, and the spring 12 is located between the limiting plate 7 and the end plate of the driving sleeve 10.

[0007] A long slot 13 is also formed on the side wall of the rotating shaft 6 , and the limiting pin 11 is movably connected in the long slot 13 .

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] The locking mechanism for a vehicle sunroof of this structural form has a simple structure, ingenious design and reasonable layout. Aiming at the problem that traditional vehicle sunroofs cannot be locked after opening, a special structure is designed, which consists of a locking frame fixed to the vehicle body and a rotating locking piece matched with the locking frame. The rotating locking piece can be connected to the locking frame when the sunroof is in an open state, so as to realize the locking between the sunroof and the vehicle body and prevent the sunroof from being closed again under the action of external force. This state is conducive to the escape of people in the vehicle and it is also convenient for rescue personnel outside the vehicle to implement rescue through the sunroof. When the sunroof needs to be closed again, it can be unlocked by simply rotating the rotating locking piece. The operation process is very simple and fast. At the same time, the manufacturing process of the locking mechanism is simple and the manufacturing cost is low. Therefore, it can be said that it has multiple advantages and is particularly suitable for promotion and application in this field. Its market prospect is very broad.

[0015] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings: Figures 1 to 7 As shown, a locking mechanism for a vehicle sunroof comprises a locking frame 1 fixedly connected to a vehicle body and a rotating locking member 2 matched with an end of the locking frame 1.

[0016] The rotary locking member 2 comprises a positioning sleeve 4 fixedly arranged on the skylight 3, and one end of the positioning sleeve 4 facing the inner side of the skylight 3 is provided with four positioning grooves 5 evenly distributed in the circumferential direction, and a rotating shaft 6 is rotatably connected inside the positioning sleeve 4, and a limiting plate 7 is provided at the end of the rotating shaft 6, and the front end is connected to a locking block 9 through a connecting pin 8, and the cross section of the locking block 9 is rectangular, and a driving sleeve 10 is movably sleeved outside the rotating shaft 6, and a limiting pin 11 distributed along its radial direction is connected to the side wall of the driving sleeve 10, and the limiting pin 11 matches the positioning groove 5, and a spring 12 is sleeved outside the rotating shaft 6, and the spring 12 is located between the limiting plate 7 and the end plate of the driving sleeve 10.

[0017] A long slot 13 is also formed on the side wall of the rotating shaft 6 , and the limiting pin 11 is movably connected in the long slot 13 .

[0018] The working process of the locking mechanism for the vehicle sunroof of the embodiment of the utility model is as follows: when it is necessary to lock the sunroof 3 in the open state after opening, the operator opens the sunroof 3 until the sunroof 3 contacts the side of the end of the locking frame 1, and the sunroof 3 stops moving under the limiting effect of the locking frame 1.

[0019] Then the operator holds the outer wall of the driving sleeve 10 and pulls it in the direction away from the locking frame 1. The driving sleeve 10 drives the limiting pin 11 to disengage from the positioning groove 5. At the same time, the limiting pin 11 moves in the long groove 13 on the rotating shaft 6. When the limiting pin 11 is separated from the positioning groove 5, the operator twists the driving sleeve 10. When the driving sleeve 10 rotates, the torque is transmitted to the rotating shaft 6 through the limiting pin 11. When the rotating shaft 6 rotates, it drives the locking block 9 to rotate through the connecting pin 8.

[0020] After the driving sleeve 10 rotates 90°, the driving sleeve 10 is released. Under the action of the spring 12, the driving sleeve 10 drives the limit pin at its end to re-enter the next group of positioning grooves 5. In this state, the rotary locking member 2 is locked and cannot be rotated arbitrarily. Since the locking block 9 is rectangular as a whole, when the locking block 9 rotates 90°, its long axis rotates to a position in contact with the end of the locking frame 1. At this time, the end of the locking frame 1 is sandwiched between the locking block 9 and the sunroof 3, that is, the sunroof 3 is connected to the locking frame 1 through the rotary locking member 2, and the sunroof 3 is locked.

[0021] When the sunroof 3 needs to be closed again, the above operation is repeated to rotate the locking block 9 90° in the opposite direction, so that the long axis of the locking block 9 is no longer in contact with the locking frame 1, and the sunroof 3 regains its freedom.
