[0042] Figure 5 The figure shows a three-dimensional view of a second bracket assembly of a vehicle sunroof mechanical assembly according to an embodiment of the present application. Figure 6 The figure shows a three-dimensional view of a second slider of a vehicle sunroof mechanical assembly according to an embodiment of the present application. Figure 7 The figure shows a three-dimensional view of a second bracket of a vehicle sunroof mechanical assembly according to an embodiment of the present application. Figure 8 The figure shows a stereoscopic view of a clamp block of a mechanical assembly of a car sunroof according to an embodiment of the present application, combined with Figure 5-Figure 8 As shown, the second bracket assembly 3 includes a second slider 31, a second bracket 32, a fixing member 33 and a clamping block 34. A plug 311 is provided at the bottom of the second slider 31 for connecting with the end plug plate 43 of the guide rail 42. One side of the second slider 31 includes a first slide 312 and a second slide 313. The first slide 312 and the second slide 313 are arranged in opposite directions, and an opening is provided at one end of the first slide 312 and the second slide 313, and a blind opening is provided at the other end, so as to ensure that the second protrusions 321 and 322 can only enter the first slide 312 and the second slide 313 from one direction.

[0043] The second protrusion 321 on the second bracket 32 ​​can be clamped on the first slide 312, and the second protrusion 322 on the second bracket can be clamped in the second slide 313. When the second slider 31 is translated, since the first slide 312 and the second slide 313 are arranged in an arc shape and face opposite directions, the second protrusion 321 can move out of the first slide 312, and the second protrusion 322 can move into the second slide 313, so that the second bracket 32 ​​is rotated, thereby lifting one end 324 of the second bracket 32. On the contrary, when the second slider 31 is translated in the opposite direction, the second protrusion 321 can move into the first slide 312, and the second protrusion 322 can move out of the second slide 313, thereby lowering one end 324 of the second bracket 32.

[0044] The end 324 of the second bracket 32 ​​is connected to the clamping block 34, and the clamping block 34 is clamped to the lifting arm 1. A hinge hole 341 is provided on the clamping block 34 for rotationally connecting with the end 324 of the second bracket 32. At the same time, an opening slot 342 is provided on the clamping block 34, so that the lifting arm 1 is clamped on the clamping block 34 through the opening slot 342, and the lifting arm 1 can move along the opening slot 342. When the end 324 of the second bracket 32 ​​is raised or lowered, the lifting arm 1 can be raised or pulled back. At the same time, in order not to affect the rotation of the second bracket 32, the other end 323 of the second bracket 32 ​​is rotatably connected to the fixing member 33. In a preferred embodiment, the other end 323 of the second bracket includes a pin, and a through hole 331 is provided on the fixing member 33.

It should be noted that the connection method between the second bracket 32 ​​and the fixing member 33 includes but is not limited to the method described above. Other methods, such as hinged connection, can also achieve the technical effect.

[0045] Fig. 9 The figure shows a stereoscopic view of a limit block of a mechanical assembly of a sunroof in an automobile according to an embodiment of the present application. One end of the limit block (not shown) includes a slot 411, and the other end 412 is connected to the guide rail 42 via a spring (not shown). Preferably, the spring is a retaining spring. The slot 411 on the limit block is used to engage the wedge block 215 at the bottom of the first slider 21, so that the first slider 21 is combined with the linkage assembly 4. Figure 1 As shown, after the first slider 21 moves, it drives the limit block to move, and the limit block pushes the guide rail 42 to move, and then further pushes the first slider 21 to move, and the wedge block 215 will be separated from the slot 411, so that the guide rail 42 moves to the maximum displacement. In this process, after the guide rail 42 moves, it will push the second slider 31 to move. After the first slider 21 and the second slider 31 move, they respectively drive the first bracket 22 and the second bracket 32 ​​to rotate, so that the lifting arm 1 is lifted or pulled back.

[0046] Fig.10The illustrated diagram is a three-dimensional diagram of a lifting arm of a mechanical assembly of a car sunroof according to an embodiment of the present application. The lifting arm 1 is used to carry the glass cover of the car sunroof. At the same time, the sunroof is opened or closed by the movement of the lifting arm. One end 12 of the lifting arm 1 is connected to the first bracket 22. A bottom plate 14 is provided at the bottom of the lifting arm 1. With this structure, the lifting arm 1 is conveniently clamped in the clamping block 34 without affecting the movement of the lifting arm 1 in the clamping block 34. In addition, the lifting arm 1 includes an opening 13, and the baffle 11 is connected to the lifting arm 1 through the opening 13. The position of the opening 13 can be designed by the structure of the first bracket assembly 2.

[0047] Fig.11 The first state diagram of the automobile sunroof mechanical assembly of an embodiment of the present application is shown. It should be noted that the first state described here refers to the state when the automobile sunroof is in a closed state. At this time, the first bracket 22 is arranged close to the first slider 21, and the second bracket 32 ​​pulls the clamping block 34 to be close to the second slider 31. With this structure, the first bracket assembly 2 and the second bracket assembly 3 are in a folded state, so that the automobile sunroof mechanical assembly provided by the present application occupies a smaller space. In the first state, the first protrusion 222 on the first bracket 22 is located at one end of the first slide 211 away from the first bend 213, and the other first protrusion 223 is located at one end of the second slide 212 away from the second bend 214. At this time, the first slider 21 is pushed to move along the AA direction shown in the figure. Since the first slider 21 is connected to the limit assembly 41, the limit assembly 41 is driven to move, and then the guide rail 42 is driven to move along the AA direction. After the guide rail 42 moves, it drives the second slider 31 to move along the AA direction. After the second slider 31 moves along the AA direction, the second protrusion 321 can move out of the first slideway 312, and the second protrusion 322 can move into the second slideway 313, so that the second bracket 32 ​​rotates, thereby lifting one end 324 of the second bracket 32. Fig.12 .

[0048] Fig.12The second state diagram of the automobile sunroof mechanical assembly of an embodiment of the present application is shown. It should be noted that the second state diagram described here refers to the middle position of the automobile sunroof opening. When the second bracket 32 ​​rotates on the second slider 31, due to the blind stop effect of the end of the second slide 313, the second bracket 32 ​​rotates to the final position. At this time, the second bracket 32 ​​lifts the lifting arm 1 to the highest position, and the second slider 31 remains in a stopped state. The first slider 21 is continuously pushed to move along the AA direction. Since the guide rail 42 stops moving under the limiting effect of the second bracket assembly 3, the first slider 21 can be separated from the clamping of the stop assembly 41 after continuing to move. At this time, the lifting arm 1 continues to move along the clamp block 34 in the AA direction, and the first protrusion 222 on the first bracket 22 gradually moves to the first bend 213 on the first slide 211, and the other first protrusion 223 gradually moves to the second bend 214 on the second slide 212. Since the first bend 213 and the second bend 214 are in opposite directions, the first bracket 22 rotates on the first slider 21, thereby lifting the other end of the lifting arm 1. After that, the first slider 21 is pushed to move, and the lifting arm 1 is moved along the AA direction, and then the sunroof of the car can be opened. Fig.13 shown.

[0049] Fig.13 The third state diagram of the automobile sunroof mechanical assembly of an embodiment of the present application is shown. It should be noted that the third state diagram here refers to the final position of the automobile sunroof being opened. At this time, both ends of the lifting arm 1 are lifted by the first bracket assembly 2 and the second bracket assembly 3 respectively, and gradually move along the AA direction under the action of the external driving device to realize the opening of the automobile sunroof.

[0050] On the contrary, when the first slider 21 is driven to move in the opposite direction of the AA direction, that is, the car sunroof gradually returns to the first state from the third state, the lifting arm 1 is gradually pulled back by the first bracket assembly 2 and the second bracket assembly 3, and the closing function of the car sunroof can be realized. It should be noted that driving the first slider 21 to move in the AA direction to open the car sunroof is only a preferred embodiment of the present application, but it does not mean that it is limited to pushing the first slider 21 to move, and the direction of opening the sunroof must be limited to the AA direction shown in the figure. Those skilled in the art can select a suitable driving position and moving direction according to actual needs, and design a suitable slide groove and slideway direction to realize the opening or closing of the car sunroof.

[0051] The automobile sunroof mechanical assembly provided by the present application is used to respectively set bracket assemblies at both ends of the lifting arm for supporting the sunroof glass, and a linkage device is set between the first bracket assembly and the second bracket assembly. After driving the first bracket assembly to move, the linkage device can be used to push the second bracket assembly to lift one side of the lifting arm, and at the same time, the first bracket in the first bracket assembly slides, so that the other side of the lifting arm is lifted, and the first bracket assembly can gradually push the lifting arm to move along the linkage device to open the sunroof. The technical solution provided by the present application is that the first bracket assembly and the second bracket assembly can be automatically folded and retracted, and the lifting arm can be gradually lifted after driving, so as to open the automobile sunroof, with good linkage effect, compact structure, small space occupation, easy manufacturing, low cost, and thus better economic benefits.

[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
