Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Combine the following Figures 1 to 4 A cold channel skylight and a control device thereof provided in an embodiment of the utility model are described.

[0033] The present embodiment provides a cold channel skylight control device, comprising: a skylight frame 1, a glass installation frame 2, a driving device 3 and a locking and positioning mechanism.

[0034] Among them, the skylight frame 1 is arranged at the end of the cold channel, the glass mounting frame 2 is embedded in the skylight frame 1 for installing glass, and a rotating shaft 4 is arranged on one side of the glass mounting frame 2, and the glass mounting frame 2 is rotatably connected to the skylight frame 1 through the rotating shaft 4; the driving device 3 is arranged on the skylight frame 1, and the driving device 3 is transmission-connected with the rotating shaft 4, and is used to drive the glass mounting frame 2 to flip around the rotating shaft 4 to open or close the cold channel; the locking and positioning mechanism includes a positioning part and a locking member, the positioning part is arranged on one of the rotating shaft 4 or the glass mounting frame 2, and the locking member is movably arranged on the skylight frame 1, and the locking member is arranged to cooperate with the positioning part when the glass mounting frame 2 closes the cold channel to lock the rotation of the rotating shaft 4 and fix the glass mounting frame 2 in the current position.

[0035] It can be known from the above scheme that the driving device 3 drives the rotating shaft 4 to rotate, so that the glass mounting frame 2 is flipped around the rotating shaft 4 to open or close the cold channel, so that the operator can easily control the opening or closing of the cold channel; by setting a locking and positioning mechanism, when the glass mounting frame 2 is in a state of closing the cold channel, the locking piece set on the skylight frame 1 cooperates with the rotating shaft 4 or the positioning part of the glass mounting frame 2 to fix the rotating shaft 4, thereby fixing the glass mounting frame 2 in the current position. Compared with the prior art, by setting a locking and positioning mechanism, when the cold channel is closed, there is no need to continue to use the driving device 3 to fix the rotating shaft 4, thereby avoiding the driving device 3 being in a load state for a long time under the action of the weight of the glass mounting frame 2 itself, which helps to improve the stability of the control system, reduce failures and safety problems caused by long-term load, and can reduce energy consumption, as well as reduce the wear between the driving device 3 and the rotating shaft 4, and extend the service life.

[0036] Optionally, the driving device 3 includes a driving motor, and a power output shaft of the driving motor is connected to the first end of the rotating shaft 4 .

[0037] In this embodiment, a first mounting groove 11 is provided on one side of the sunroof frame 1, the drive motor is provided in the first mounting groove 11, and the first end of the rotating shaft 4 extends axially into the first mounting groove 11 and is connected to the power output shaft of the drive motor. Figure 1 As shown, the first end of the rotating shaft 4 axially passes through the skylight frame 1 and enters the first mounting groove 11. By arranging the driving motor in the first mounting groove 11, the space occupied by the driving motor is reduced, and the space can be utilized to the maximum extent. In addition, the first mounting groove 11 can provide a protective effect for the driving motor to prevent the driving motor from being interfered with or damaged by external factors.

[0038] In some embodiments, a second mounting groove 12 is provided on the other side of the sunroof frame 1, the second end of the rotating shaft 4 is located in the second mounting groove 12, the positioning portion is provided at the second end of the rotating shaft 4, and the locking member is movably provided in the second mounting groove 12. Figure 1 As shown, the first mounting groove 11 and the second mounting groove 12 are relatively arranged on both sides of the skylight frame 1, the second end of the rotating shaft 4 is located in the second mounting groove 12, and a positioning portion is arranged at the second end of the rotating shaft 4. When the glass mounting frame 2 closes the cold channel, the locking member can cooperate with the positioning portion to fix the rotating shaft 4 at the current angle, thereby locking the position of the glass mounting frame 2. At this time, the operation of the driving device 3 can be stopped, and the locking member and the positioning portion can be used to limit the rotating shaft 4.

[0039] Optionally, the positioning portion is a positioning groove 5, and the locking member is a plug-in block 6. For example, the positioning groove 5 is a rectangular groove, an elliptical groove, a polygonal groove or an irregular groove, and the shape of the plug-in block 6 is adapted to the positioning groove 5, that is, the locking member and the positioning portion are matched with each other. Figure 2 and Figure 3 As shown, the positioning groove 5 is a rectangular groove, and the plug-in block 6 is a strip-shaped protrusion. When the glass mounting frame 2 is rotated to the position to close the cold channel, the locking piece can be plugged and matched with the positioning part to prevent the rotating shaft 4 from continuing to rotate.

[0040] Of course, the positioning portion may be the plug-in block 6 , the locking member may be the positioning groove 5 , and the plug-in block 6 may be matched with the positioning groove 5 .

[0041] In other embodiments, the skylight frame 1 is provided with a second mounting groove 12, the locking member is movably provided in the second mounting groove 12, the positioning portion is provided on the outside of the glass mounting frame 2, and a through hole for the locking member to pass through is provided on one side of the second mounting groove 12 corresponding to the glass mounting frame 2. In other words, the positioning portion is provided on the outside of the glass mounting frame 2, and the position of the glass mounting frame 2 is directly fixed by the cooperation between the locking member and the positioning portion. For example, a positioning groove 5 or a protrusion is provided on the outside of the glass mounting frame 2, and when the glass mounting frame 2 is rotated to a position where the cold channel is closed, the locking member extends through the through hole and cooperates with the positioning portion to lock the glass mounting frame 2 in the current position.

[0042] Furthermore, a guiding inclined surface 51 is provided at one end of the positioning groove 5 facing the plug-in block 6. Figure 3 As shown, guide slopes 51 are provided at the edges around the end of the positioning groove 5 to facilitate the plug-in block 6 to quickly and smoothly enter the positioning groove 5, which is beneficial to improving work efficiency.

[0043] In this embodiment, a pushing component 7 is also included, which includes a connecting plate 71, an elastic member 72, a first electromagnet 73 and a second electromagnet 74. The outer side of the connecting plate 71 is connected to the locking member, the first electromagnet 73 is arranged on the inner side of the connecting plate 71, and the second electromagnet 74 is correspondingly arranged on the inner wall of the second mounting groove 12, and the magnetic poles of the first electromagnet 73 and the second electromagnet 74 on the opposite side are the same, the elastic member 72 is arranged as a spring, and the two ends of the elastic member 72 are respectively connected to the inner side of the connecting plate 71 and the inner wall of the second mounting groove 12, so as to generate a reset trend when the connecting plate 71 approaches the glass mounting frame 2.

[0044] In this arrangement, by energizing the first electromagnet 73 and the second electromagnet 74, since the magnetic poles on the opposite side of the first electromagnet 73 and the second electromagnet 74 are arranged in the same manner, the first electromagnet 73 and the second electromagnet 74 after energization push the connecting plate 71 to move toward the glass mounting frame 2 under the action of magnetic force, and finally enable the locking member to cooperate with the positioning member, and after power is cut off, the connecting plate 71 and the first electromagnet 73 are pulled back to the initial position by the restoring force of the elastic member 72 to release the connection between the locking member and the positioning member. In this state, the glass mounting frame 2 is driven to rotate by the driving motor.

[0045] Furthermore, it also includes a guide assembly, which includes a slide rod 75 and a sleeve 76. The sleeve 76 is sleeved on the slide rod 75 and slidably connected thereto, one end of the sleeve 76 away from the slide rod 75 is connected to the inner side of the connecting plate 71, and one end of the slide rod 75 away from the sleeve 76 is connected to the inner wall of the second mounting groove 12; of course, it is also possible that one end of the sleeve 76 away from the slide rod 75 is connected to the inner wall of the second mounting groove 12, and one end of the slide rod 75 away from the sleeve 76 is connected to the inner side of the connecting plate 71.

[0046] like Figure 3 As shown, two sets of guide components can be set, a pair of sleeves 76 are spaced apart at both ends of the connecting plate 71, a first electromagnet 73 is set between the pair of sleeves 76, and the elastic member 72 can be sleeved on the sleeve 76. The sliding connection between the sleeve 76 and the slide rod 75 ensures the stability of the movement of the locking member, and ensures that the locking member can cooperate with the positioning part through movement when the glass mounting frame 2 is rotated to the position to close the cold channel.
