Sunroof cocking structure

Abstract

This utility model relates to a sunroof tilting structure for automobiles. The tilting structure includes a tilting arm, a slider, and a guide mechanism. The slider has a front groove and a rear groove. The front fulcrum of the tilting arm is located in the front groove, and the rear fulcrum is located in the rear groove. The guide mechanism is vertically arranged and connects with either the front or rear fulcrum. The slider moves horizontally, and the front and rear fulcrums of the tilting arm move relative to each other within their respective front and rear grooves. Under the action of the guide mechanism, the front and rear fulcrums of the tilting arm can only move vertically up and down. By configuring the tilting arm, slider, and guide mechanism, the front fulcrum moves both along the trajectory of the front groove of the slider and up and down along the guide mechanism; the rear fulcrum moves along the trajectory of the rear groove of the slider. Only the forward and backward movement of the structure is needed to achieve changes in the fulcrum height, thereby changing the front and rear states of the glass. The sunroof motor drives the flexible shaft forward and backward, and the flexible shaft is fixed to the mechanism structure, thus achieving fully electric drive.

Description

Technical Field

[0001] This utility model relates to a car sunroof, specifically to a car sunroof tilting structure. Background Technology

[0002] With the increasing popularity of sunroofs, the demand for various sunroof functions is also growing. Traditional functions such as light transmission, light blocking, and ventilation can be achieved through different structural forms. Sunroof light transmission: Light is allowed to pass through by choosing materials such as glass for the sunroof cover. Sunroof light blocking: Strong light is blocked and weak light is transmitted by the rolling up and unfolding of the sunshade system. Sunroof ventilation: Air is quickly drawn out of the vehicle while the vehicle is in motion by tilting or sliding the rear of the glass, and fresh air is replenished by the air conditioning intake.

[0003] The traditional structure of existing sunroof ventilation systems uses a sunroof motor to drive a flexible shaft, which in turn drives a mechanism to tilt or slide the rear of the glass. The structural principle is as follows: Figure 1 As shown, the glass is fixedly connected to the lifting arm 01 and moves together with the lifting arm 01 as it tilts and slides backward. When the front fulcrum 02 of the lifting arm is in the lowered position, the rear tilting arm 04 flips and lifts up, and the rear tilting arm fulcrum 03 drives the rear side of the lifting arm 01 to lift, thereby tilting the glass. When the front fulcrum 02 of the lifting arm moves upward and slides backward, and the rear tilting arm fulcrum 03 slides synchronously in the upper groove of the lifting arm 01, the glass slides backward. Similarly, the glass closing principle is the reverse of its operation sequence.

[0004] However, for special scenarios, such as the use of sunroofs in buses, there is a need for sunroof glass to tilt up at the front, rear, or both simultaneously. Currently, there are sunroofs on the market that can achieve this function manually, but due to the height of the bus roof, operation is quite complex and laborious. Therefore, it is necessary to develop a structure that electrically drives the glass to tilt up at the front, rear, or both simultaneously. Utility Model Content

[0005] To solve the above problems, this utility model provides a sunroof tilting structure, which is particularly suitable for bus sunroofs. A single mechanism can achieve four states of the sunroof: front tilting, rear tilting, full tilting, and full closing.

[0006] The technical solution adopted by this utility model is: a sunroof tilting structure for automobiles, characterized in that: it includes a tilting arm, a slider, and a guide mechanism; the slider is provided with a front slide groove and a rear slide groove; the front support point of the tilting arm is set in the front slide groove, and the rear support point is set in the rear slide groove; the guide mechanism is vertically arranged and is connected to the front or rear support point; the slider moves horizontally, and the front and rear support points of the tilting arm move relative to each other in the corresponding front and rear slide grooves; under the action of the guide mechanism, the front and rear support points of the tilting arm can only move vertically up and down.

[0007] Preferably, the guiding mechanism is a front straight groove, and the front support point of the lifting arm is simultaneously located in the front sliding groove and the front straight groove.

[0008] Preferably, the front chute includes a first front high node, a first front low node, a second front low node and a second front high node arranged in sequence, a first front upslope section between the first front high node and the first front low node, a front smooth section between the first front low node and the second front low node, and a second front upslope section between the second front low node and the second front high node. The rear chute includes a first rear low node, a second rear low node, a first rear high node, and a second rear high node arranged sequentially. A first rear smooth section is provided between the first rear low node and the second rear low node. A rear uphill section is provided between the second rear low node and the first rear high node. A second rear smooth section is provided between the first rear high node and the second rear high node.

[0009] Preferably, with the glass fully closed, the front pivot is at the first front low position node, and the rear pivot is at the second rear low position node.

[0010] Preferably, in the glass-tilted state, the front fulcrum moves from the first front low node to the first front high node via the first front upslope section; at the same time, the rear fulcrum moves from the second rear low node to the first rear low node via the first rear smooth section.

[0011] Preferably, in the glass upturned state, the front support point moves from the first front low node to the second front low node via the front smooth section; at the same time, the rear support point moves from the second rear low node to the first rear high node via the rear uphill section.

[0012] Preferably, in the fully tilted glass state, the front fulcrum moves from the second front low node to the second front uphill section to the second front high node; at the same time, the rear fulcrum moves from the first rear high node to the second rear smooth section to the second rear high node.

[0013] The beneficial effects of this utility model are as follows: by setting up a lifting arm, a slider, and a guide mechanism, the glass is fixedly connected to the lifting arm. The front fulcrum moves along the front slide groove trajectory of the slider and moves up and down along the guide mechanism; the rear fulcrum moves along the rear slide groove trajectory of the slider. Only the forward and backward movement of the structure is needed to realize the change of the fulcrum height, thereby realizing the change of the front and rear state of the glass; the flexible shaft is driven forward and backward by the sunroof motor, and the flexible shaft is fixed to the mechanism structure, thereby realizing the all-electric drive.

Guide mechanism. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-11As shown, this utility model discloses a car sunroof tilting structure, including a tilting arm 1, a slider 2, and a guide mechanism 3. The slider 2 is provided with a front slide groove 21 and a rear slide groove 22. The front fulcrum 11 of the tilting arm 1 is located in the front slide groove 21, and the rear fulcrum 12 is located in the rear slide groove 22. The guide mechanism 3 is vertically arranged and is connected to the front fulcrum 11 or the rear fulcrum 12. The slider 2 moves horizontally, and the front fulcrum 11 and the rear fulcrum 12 of the tilting arm 1 move relative to each other in the corresponding front slide groove 21 and rear slide groove 22. Under the action of the guide mechanism 3, the front fulcrum 11 and the rear fulcrum 12 of the tilting arm 1 can only move vertically up and down. By setting up a lifting arm 1, a slider 2, and a guide mechanism 3, the glass is fixedly connected to the lifting arm 1. The front fulcrum 11 moves along the trajectory line of the front slide groove 21 of the slider 2 and moves up and down along the guide mechanism 3; the rear fulcrum 12 moves along the trajectory line of the rear slide groove 22 of the slider 2. Only by realizing the forward and backward movement of the structure can the height of the fulcrum be changed, thereby realizing the change of the front and rear state of the glass; the flexible shaft is driven forward and backward by the sunroof motor, and the flexible shaft is fixed to the mechanism structure, thereby realizing the all-electric drive.

[0017] In this embodiment, the guide mechanism 3 is a front straight groove, and the front fulcrum 11 of the lifting arm 1 is simultaneously located in the front sliding groove and the front straight groove. This ensures that the fulcrum can only move up and down without shifting position.

[0018] Combination Figure 11 As shown, in this embodiment, the front slide 21 includes a first front high node 211, a first front low node 212, a second front low node 213, and a second front high node 214 arranged sequentially. A first front upslope section 215 is provided between the first front high node 211 and the first front low node 212. A front smooth section 216 is provided between the first front low node 212 and the second front low node 213. A second front upslope section 217 is provided between the second front low node 213 and the second front high node 214. The rear chute 22 includes a first rear low node 221, a second rear low node 222, a first rear high node 223, and a second rear high node 224 arranged sequentially. A first rear smooth section 225 is provided between the first rear low node 221 and the second rear low node 222. A rear uphill section 226 is provided between the second rear low node 222 and the first rear high node 223. A second rear smooth section 227 is provided between the first rear high node 223 and the second rear high node 224.

[0019] With the glass fully closed, the front pivot 11 is at the first front low node 212, and the rear pivot 12 is at the second rear low node 222.

[0020] When the glass is tilted upwards, the front fulcrum 11 moves from the first front low node 212 through the first front upslope section 215 to the first front high node 211; at the same time, the rear fulcrum 12 moves from the second rear low node 222 through the first rear smooth section 225 to the first rear low node 221.

[0021] When the glass is in a tilted-up state, the front fulcrum 11 moves from the first front low node 213 through the front smooth section 214 to the second front low node 213; at the same time, the rear fulcrum 12 moves from the second rear low node 222 through the rear uphill section 226 to the first rear high node 223.

[0022] When the glass is fully tilted up, the front pivot 11 moves from the second front low node 213 through the second front uphill section 217 to the second front high node 214; at the same time, the rear pivot 12 moves from the first rear high node 223 through the second rear smooth section 227 to the second rear high node 224.

[0023] As can be seen from the principle, the sequence of glass state changes is completely affected by the changes in the forward and backward trajectory lines. For fully electric control to achieve control of the four glass states (distinguished as node positions), it is only necessary for the controller to drive the motor to rotate a fixed number of forward and reverse rotations. Regarding the four state changes, the node position control can be achieved by using a knob switch to select the gear position, or by using forward and backward buttons to achieve sequential control of the node positions.

[0024] This invention divides the trajectory line into three segments and four nodes. By combining different combinations of the front and rear trajectory lines, different sequences of glass state changes are achieved. When the trajectory line is at the front, the front fulcrum is at a high node, and the rear fulcrum is at a low node, resulting in a forward-tilted glass state. As the trajectory line moves forward, the front fulcrum descends to a low node on the uphill section, and the rear fulcrum remains at a low node on the smooth section, resulting in a fully closed glass state. When the trajectory line moves forward again, the front fulcrum remains at a low node on the smooth section, and the rear fulcrum rises to a high node on the uphill section, resulting in a backward-tilted glass state. When the trajectory line moves forward again, the front fulcrum rises to a high node on the uphill section, and the rear fulcrum remains at a high node on the smooth section, resulting in a fully tilted glass state. Similarly, based on the combination of nodes in the stroke segments, 24 different sequences of glass state changes can be achieved, as shown in the table below: The foregoing has shown and described the basic principles and main structural features of this utility model. This utility model is not limited to the above examples; various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
