DETAILED DESCRIPTION

[0066] The present application will be described in detail below in conjunction with the drawings and specific embodiments. It should be noted that in the drawings or description, similar or identical parts are denoted by the same reference numerals, and the implementation not shown or described in the drawings is in a form known to those skilled in the art. In the description of the present application, the terms "first", "second", etc. are only used for differentiation and cannot be understood as indicating or implying relative importance.

[0067] As Figure 1 shown, the present embodiment provides a sunroof assembly, which mainly includes a sunroof frame 100, a fixed glass assembly 200 and a movable glass assembly 300. The sunroof assembly is mainly applied to the vehicle model disclosed in the patent with application number 202210050469.0, and covers most of the area of the roof, and the coverage area of the fixed glass assembly 200 and the movable glass assembly 300 is also relatively large. In the case of a closed state in the vehicle and a large temperature difference between the inside and outside of the vehicle, the sunroof glass of the sunroof assembly is extremely prone to fogging or frosting, which reduces the light-transmitting effect of the sunroof glass and makes the user experience poor. In order to solve this problem, an electric heating element is added to the sunroof glass in the present embodiment to achieve the purpose of defogging and defrosting the sunroof glass.

[0068] As Figure 2As shown, in this embodiment, the sunroof frame 100 has a first light-transmitting area 110 and a second light-transmitting area 120. The first light-transmitting area 110 is a hollow area near the front of the vehicle, and the second light-transmitting area 120 is a hollow area near the rear of the vehicle. Specifically, the sunroof frame 100 includes a front crossbeam 130, a middle crossbeam 140, and two side long beams 150. The front crossbeam 130 and the middle crossbeam 140 are arranged parallel to each other, and the two side long beams 150 are symmetrically arranged at both ends of the front crossbeam 130 and the middle crossbeam 140. The first light-transmitting area 110 is surrounded by the front crossbeam 130, the middle crossbeam 140, and the two side long beams 150, and the second light-transmitting area 120 is surrounded by the middle crossbeam 140 and the two side long beams 150. This forms the basic framework of the sunroof frame 100.

[0069] like Figure 2 and Figure 7 As shown, in this embodiment, the fixed glass assembly 200 is fixedly installed on the sunroof frame 100 and covers the first light-transmitting area 110. Specifically, the fixed glass assembly 200 includes a fixed sunroof glass 210 and a fixed glass insert 220. The fixed sunroof glass 210 is bonded to the fixed glass insert 220, making the fixed sunroof glass 210 and the fixed glass insert 220 a single unit, thereby increasing the strength of the fixed sunroof glass 210. The fixed glass insert 220 is bonded to the first light-transmitting area 110 of the sunroof frame 100. To prevent fogging or frost formation on the fixed sunroof glass 210, a fixed glass heating element 230 for defrosting and defogging is installed on the fixed sunroof glass 210.

[0070] like Figure 2 and Figure 3 As shown, in this embodiment, the movable glass assembly 300 is slidably mounted on the sunroof frame 100 along its length. When the movable glass assembly 300 slides to a position near the rear of the vehicle, it can cover the second light-transmitting area 120. The movable glass assembly 300 includes a movable sunroof glass 310 and a movable glass insert 320. The movable glass insert 320 is designed in a "U" shape, with a glass mounting position in the middle that fits the movable sunroof glass 310. The movable sunroof glass 310 is bonded to the glass mounting position, thereby integrating the movable sunroof glass 310 and the movable glass insert 320 into one piece, increasing the strength of the movable sunroof glass 310. To prevent fogging or frost formation on the movable sunroof glass 310, a movable glass heating element 330 for defrosting and defogging is installed on the movable sunroof glass 310.

[0071] By the technical solutions, the fixed glass heating element 230 is installed on the fixed sunroof glass 210, and the movable glass heating element 330 is installed on the movable sunroof glass 310. The driver or passenger opens the fixed glass heating element 230 and / or the movable glass heating element 330 according to the specific situation, so as to achieve the effect of defrosting and demisting the fixed sunroof glass 210 and / or the movable sunroof glass 310, keep the fixed sunroof glass 210 and / or the movable sunroof glass 310 at a high light transmittance, and improve the driving experience of the driver or passenger.

[0072] In the embodiment, the movable glass heating element 330 is mainly electrically connected with the vehicle control system, and the on-off of the movable glass heating element 330 is controlled by the vehicle control system.

[0073] In the embodiment, since the movable glass assembly 300 is arranged in a slidable form, the movable glass assembly 300 slides while carrying the movable glass heating element 330. The heating of the movable glass heating element 330 needs a wire harness connected between the movable glass heating element 330 and the vehicle control system. When the movable glass heating element 330 slides with the movable glass assembly 300, the wire harness will frequently bend, twist and make other actions, which increases the risk of damage of the wire harness. In order to solve this problem, the embodiment adopts a contact type electrical connector to supply power to the movable glass heating element 330, which can effectively reduce the risk of damage of the wire harness, thereby reducing the failure rate of the movable glass heating element 330.

[0074] As shown in FIG. 1, the vehicle 100 includes a fixed sunroof glass 210, a movable sunroof glass 310, a fixed glass heating element 230 and a movable glass heating element 330. Figures 3-6As shown, specifically, an electronic connector 340 is electrically connected to the movable glass heating element 330 via a wiring harness. The electronic connector 340 is fixedly installed on the movable glass assembly 300 on the side facing the vehicle interior. A contact connector 160 that mates with the electronic connector 340 is installed on the sunroof frame 100. The contact connector 160 is electrically connected to the vehicle control system via a wiring harness. It should be noted that the vehicle control system can control the contact connector 160 to be energized or de-energized. When the movable glass assembly 300 slides to cover the second light-transmitting area 120, the electronic connector 340 matches the contact connector 160. At this time, the movable glass heating element 330 can be energized, and the vehicle control system can control the movable glass heating element 330 to be energized and heated, thereby performing defrosting and defogging operations on the movable sunroof glass 310. When the movable glass assembly 300 slides to the uncovered second light-transmitting area 120, the electronic connector 340 separates from the contact connector 160. At this time, the movable glass heating element 330 is directly de-energized and is not controlled by the vehicle control system. Furthermore, when the movable glass assembly 300 is not covered in the second light-transmitting area 120, the interior space is always connected to the outside, and the movable sunroof glass 310 will hardly fog up or frost, so the defrosting and defogging function is not needed. By designing contact-type electrical connectors, the movable glass heating element 330 can ensure normal defrosting and defogging functions, while reducing the risk of damage to the wiring harness connecting the movable glass heating element 330 to the vehicle control system. This reduces after-sales maintenance costs and improves user experience and satisfaction.

[0075] like Figures 3-6 As shown, in this embodiment, the electronic connector 340 is provided with a plurality of spring-loaded pin structures 341, and the contact connector 160 is provided with a plurality of copper sheets 161 that cooperate with the spring-loaded pin structures 341. Each copper sheet 161 corresponds one-to-one with a spring-loaded pin structure 341. With this arrangement, when all the spring-loaded pin structures 341 and their corresponding copper sheets 161 come into contact, the movable glass heating element 330 can connect to the vehicle control system, thereby enabling the movable glass heating element 330 to normally receive control signals from the vehicle control system.

[0076] In another embodiment, the engagement between the electronic connector 340 and the contact connector 160 can also employ a non-contact electrical connection structure, such as an induction coil structure similar to that in a wireless charging structure.

[0077] like Figure 3 and Figure 4As shown in the drawings, in the embodiment, the movable glass electric heating element 330 includes a plurality of defrosting and demisting lines A331 and two shunt busbars A332, the defrosting and demisting lines A331 and the shunt busbars A332 are arranged on the side of the movable sunroof glass 310 facing the vehicle interior in a printed manner, and the materials of the defrosting and demisting lines A331 and the shunt busbars A332 are preferably silver alloy. Each defrosting and demisting line A331 extends along the width direction of the movable sunroof glass 310 from one side to the other side of the movable sunroof glass 310, the specific shape of each defrosting and demisting line A331 is designed according to the curvature of the movable sunroof glass 310, and the plurality of defrosting and demisting lines A331 are uniformly arranged along the length direction of the movable sunroof glass 310. The two shunt busbars A332 are connected at the two ends of all the defrosting and demisting lines A331, so as to connect all the defrosting and demisting lines A331 in parallel to form a parallel circuit. In this way, when the two shunt busbars A332 are powered, all the defrosting and demisting lines A331 can generate heat, thereby defrosting and demisting the movable sunroof glass 310 and improving the light transmittance of the movable sunroof glass 310.

[0078] As shown in the drawings, Figure 3 and Figure 4 In the embodiment, the number of the electronic connecting pieces 340 and the number of the surface connecting pieces 160 are both two, and the two electronic connecting pieces 340 are matched with the two surface connecting pieces 160 respectively. The middle part of each shunt busbar A332 is provided with a power supply point A333, and the two power supply points A333 are connected with power supply connectors A350, the power supply connectors A350 can be directly welded on the movable glass assembly 300, and the two power supply connectors A350 are electrically connected with the two electronic connecting pieces 340 through the wire harness. In this way, when the two electronic connecting pieces 340 are in contact with the two surface connecting pieces 160 respectively, the shunt busbar A332 and the defrosting and demisting line A331 can be normally powered and heated. In addition, the power supply point A333 is arranged in the middle part of the shunt busbar A332, which can also improve the heating efficiency of all the defrosting and demisting lines A331.

[0079] As shown in the drawings, Figure 5 In the embodiment, the surface connecting piece 160 is connected with a vehicle connector 162 through the wire harness, and the vehicle connector 162 is mainly used for connecting the vehicle control system. By arranging the vehicle connector 162, the disassembly and assembly of the connecting line between the surface connecting piece 160 and the vehicle control system are facilitated.

[0080] As shown in the drawings, Figure 7 and Figure 8As shown in the figure, in the embodiment, the fixed glass electric heating element 230 includes several defrosting and demisting lines B231 and two shunt busbars B232. The defrosting and demisting lines B231 and the shunt busbars B232 are arranged on the side of the fixed sunroof glass 210 facing the vehicle interior in a printed manner, and the defrosting and demisting lines B231 and the shunt busbars B232 are preferably silver alloy. Each defrosting and demisting line B231 extends along the width direction of the fixed sunroof glass 210 from one side to the other side, and the several defrosting and demisting lines B231 are uniformly arranged along the length direction of the fixed sunroof glass 210. The two shunt busbars B232 are connected at both ends of all the defrosting and demisting lines B231, so that all the defrosting and demisting lines B231 are connected in parallel to form a parallel circuit. In this way, when the two shunt busbars B232 are powered, all the defrosting and demisting lines B231 can generate heat, thereby defrosting and demisting the fixed sunroof glass 210 and improving the light transmittance of the fixed sunroof glass 210.

[0081] As shown in the figure, Figure 7 and Figure 8 In the embodiment, since the position of the fixed glass assembly 200 is always fixed, the position of the fixed glass electric heating element 230 also does not change, and the fixed glass electric heating element 230 can be directly connected to the vehicle control system through a wire harness. Specifically, the middle part of each of the two shunt busbars B232 is provided with a power-on point B233, and the two power-on points B233 are connected with a power-on connector B240. The power-on connector B240 can be directly welded on the fixed glass assembly 200, and the two power-on connectors B240 are connected to the vehicle control system through a wire harness. In this way, the fixed glass electric heating element 230 is directly connected to the vehicle control system, which facilitates the control of the fixed glass electric heating element 230 by the vehicle control system.

[0082] As shown in the figure, Figure 2 and Figure 9 In the embodiment, the sunroof assembly further includes a movable glass sliding mechanism 400. The movable glass sliding mechanism 400 is mainly used to drive the movable glass assembly 300 to slide along the length direction of the sunroof frame 100, so as to realize automatic control of the movable glass assembly 300 and improve the user experience.

[0083] As shown in the figure, Figure 9 and Figure 10As shown, in the embodiment, the movable glass sliding mechanism 400 comprises slide rails 410, sliding screws 420, driving gears 430, driving motors 440 and connecting rod lifting assemblies 450. Among them, the number of slide rails 410, sliding screws 420 and connecting rod lifting assemblies 450 is two, two slide rails 410 are respectively installed on two side long beams 150 by bolt connection, and the slide rails 410 are arranged along the length direction of the side long beam 150. Two connecting rod lifting assemblies 450 are respectively slidingly installed on two slide rails 410, two sides of the movable glass assembly 300 are respectively fixed on the two connecting rod lifting assemblies 450, and the two connecting rod lifting assemblies 450 drive the movable glass assembly 300 to move from the rear of the sunroof frame 100 to the front of the sunroof frame 100. The driving motor 440 is bolted in the middle of the front cross beam 130, the driving gear 430 is fixed on the output shaft of the driving motor 440 by key connection, and the driving gear 430 is driven to rotate by the driving motor 440. Part of the structure of the two sliding screws 420 is respectively clamped in the two slide rails 410, and the sliding screw 420 can slide along the length direction of the slide rail 410. One end of the two sliding screws 420 is respectively connected with the connecting rod lifting assembly 450 on the same side, and the other end of the sliding screw 420 extends to the front cross beam 130 and engages with the driving gear 430. The driving motor 440 drives the driving gear 430 to rotate, and then the connecting rod lifting assembly 450 is driven to slide along the length direction of the slide rail 410 by the sliding screw 420, so as to drive the movable glass assembly 300 to move. It should be noted that the cooperation mode of the sliding screw 420 and the driving gear 430 can refer to the transmission structure of the existing vehicle electric sunroof.

[0084] As Figure 1 and Figure 11 As shown, in the embodiment, since the movable glass assembly 300 is in a flat state with the fixed glass assembly 200 in the closed state, and the end of the movable glass assembly 300 close to the vehicle head abuts against one end of the fixed glass assembly 200, at this time, the movable glass assembly 300 is not convenient to move towards the vehicle head side. Therefore, in the embodiment, the connecting rod lifting assembly 450 is used to enable the movable glass assembly 300 to be lifted to a certain height in the initial opening stage, and to enable the movable glass assembly 300 to be lowered to reset in the final closing stage, so as to facilitate the smooth opening and closing of the movable glass assembly 300. In addition, by setting the lifting assembly, the contact between the electronic connecting piece 340 and the touch surface connecting piece 160 is facilitated.

[0085] As Figures 11-13As shown, specifically, the connecting rod lifting assembly 450 includes a connecting plate 451, two rotating arms 452 and two sliding blocks 453, the connecting plate 451 is fixed with the movable glass insert 320 of the movable glass assembly 300 through bolts, one end of each of the two rotating arms 452 is hingedly connected to the two ends of the connecting plate 451, the other end of each of the two rotating arms 452 is hingedly connected with the two sliding blocks 453, the two sliding blocks 453 are slidingly installed on the slide rail 410, and the sliding block 453 close to the front end of the vehicle is connected with one end of the sliding screw 420. The connecting rod lifting assembly 450 has two states, which are an open state and a closed state, when the sliding screw 420 slides towards the front end of the vehicle and drives the sliding block 453 connected therewith to slide towards the front end of the vehicle, the rotating arm 452 rotates due to the blocking of the fixed glass assembly 200 on the movable glass assembly 300, and then forces the connecting rod lifting assembly 450 to deform to the open state, thereby lifting the movable glass assembly 300, when the horizontal height of the movable glass assembly 300 is higher than that of the center glass assembly of the roof; when the sliding screw 420 slides towards the rear end of the vehicle, the sliding block 453 close to the rear end of the vehicle slides to the end of the slide rail 410 close to the rear end, and the sliding block 453 is blocked and no longer advances, at this time, the connecting rod lifting assembly 450 resets to the closed state, thereby lowering the movable glass assembly 300, and achieving the closing of the movable glass assembly 300.

[0086] As shown in the drawings, Figure 12 In this embodiment, one end of the sliding screw 420 is fixed with a clamping block 421, and the sliding block 453 close to the front end of the vehicle has a clamping groove 454 matched with the clamping block 421. By such arrangement, when the clamping block 421 is clamped into the clamping groove 454, the connection between the sliding screw 420 and the sliding block 453 can be achieved, and the fixing and dismounting between the sliding screw 420 and the sliding block 453 are facilitated.

[0087] As shown in the drawings, Figure 2 In this embodiment, the sunroof frame 100 is installed with a front decoration piece 170 on the front cross beam 130, and the front decoration piece 170 is installed on the front cross beam 130 in a clamping manner; the sunroof frame 100 is installed with a side decoration piece 180 on each of the side long beams 150, and the side decoration piece 180 is also installed on the side long beam 150 in a clamping manner.
