[0040] The specific implementation of the utility model is described below in conjunction with the accompanying drawings.
[0041] like Figure 1-Figure 6As shown, the rolling door machine with waterproof and dustproof functions of this embodiment includes an upper shell 3 and a lower shell 4, the upper shell 3 and the lower shell 4 are detachably sealed and connected, and a sealed cavity is formed between the upper shell 3 and the lower shell 4;
[0042] A driving component 5 is arranged in the sealed cavity, and also includes a central shaft 2 connected to the driving component 5, one end of the central shaft 2 is located outside the upper shell 3, and the other end of the central shaft 2 is located outside the lower shell 4, and both the upper shell 3 and the lower shell 4 are sealed and connected to the central shaft 2;
[0043] A transmission gear 6 is disposed outside the upper housing 3, a gear shaft of the transmission gear 6 passes through the upper housing 3 and is transmission-connected to the driving component 5, and the gear shaft is sealed and connected to the upper housing 3;
[0044] A transmission chuck 1 is rotatably mounted on one end of the central shaft 2 , and the transmission chuck 1 is transmission-connected to a transmission gear 6 .
[0045] Specifically, in order to improve the waterproof and dustproof performance of the rolling door machine, an upper shell 3 and a lower shell 4 are arranged outside the driving component 5, so that the driving component 5 is wrapped in a sealed cavity;
[0046] One end of the central shaft 2 located outside the lower shell 4 is the connection end of the rolling door machine with the installation position. The central shaft 2 is the main load-bearing component of the rolling door machine, used to fix the driving component 5, the upper shell 3 and the lower shell 4, and is sealed between the upper shell 3 and the lower shell 4. The central shaft 2 also provides the rotation and installation position of the transmission chuck 1;
[0047] The gear shaft of the transmission gear 6 is sealedly connected to the upper housing 3, so that the power of the driving component 5 is output to the outside of the housing, while ensuring the sealing of the sealing cavity.
[0048] By taking the central axis 2 as a reference, fixing the driving component 5 on the central axis 2 and sealingly installing the upper shell 3 and the lower shell 4 for accommodating the driving component 5, the transmission gear 6 connected to the transmission chuck 1 is sealed and connected to the upper shell 3, so that the electrical components are placed in a sealed space, thereby improving the waterproof and dustproof performance of the rolling door machine, extending the service life of the rolling door machine, and expanding the scope of use of the rolling door machine.
[0049] like Figure 4-Figure 8 As shown, the first sealing ring 412 is also included, and the end edges of the upper shell 3 and the lower shell 4 are sealed and connected through the first sealing ring 412. Specifically, a recessed groove is provided at the edge of the lower shell 4, and the first sealing ring 412 is placed in the recessed groove. A flange matching the recessed groove is provided at the edge of the upper shell 3, and the flange presses the first sealing ring 412 inside the recessed groove to form a detachable sealing structure. The upper shell 3 and the lower shell 4 are connected by fasteners.
[0050] like Figure 4 , Figure 7As shown, a controller 7 is also arranged in the sealed cavity, and the upper shell 3 includes a main shell 31 and a sub-shell 33, the sub-shell 33 corresponds to the controller 7, the sub-shell 33 is detachably sealed and connected to the main shell 31, and the controller 7 is detachably connected to the lower shell 4. Specifically, the controller 7 is electrically connected to the driving component 5, and the controller 7 includes components such as a circuit board, which are used to control and record the working state of the driving component 5; when the sub-shell 33 is disassembled, the controller 7 is exposed, which is convenient for the inspection and replacement of the controller 7; the upper shell 3 and the lower shell 4 are usually non-metallic (such as plastic material) injection molding; the relatively light controller 7 is installed on the lower shell 4, which reduces the size of the steel component of the rolling door machine, that is, reduces the size of the mounting plate 52 in the driving component 5, and reduces the overall weight of the rolling door machine.
[0051] like Figure 5-Figure 7 As shown, it also includes a second sealing ring 331 , and the auxiliary housing 33 is sealed and connected to the main housing 31 through the second sealing ring 331 .
[0052] like Figure 5-Figure 7 As shown, a circular retaining ring 32 is disposed outside the upper housing 3, and the outer peripheral surface of the transmission chuck 1 is located inside the retaining ring 32 and is concentric with the retaining ring 32. Specifically, the transmission gear 6 is located inside the transmission chuck 1, and the retaining ring 32 is used to block water or dust from the outside of the transmission chuck 1, reduce the possibility of water or dust entering the transmission chuck 1 from the gap between the transmission chuck 1 and the upper housing 3, and play a protective role in sealing the gear shaft of the transmission gear 6.
[0053] Specifically, the gear shaft is sealed by a sealing ring, such as Figure 2 As shown, a third sealing ring 61 is also included, and the gear shaft is sealed and connected to the upper housing 3 via the third sealing ring 61 .
[0054] like Figure 4 As shown, the structure of the driving component 5 includes a mounting plate 52 , on which a driving motor 51 is fixedly mounted. The output end of the driving motor 51 is transmission-connected to the gear shaft, and the mounting plate 52 is fixedly connected to the central shaft 2 .
[0055] The mounting plate 52 and the central shaft 2 can be an integral structure or a separate structure. When the mounting plate 52 and the central shaft 2 are separate structures, such as Figure 6 , Figure 9-10 As shown, a through hole 520 is provided on the mounting plate 52, one end of the central axis 2 is a limit end 21, and the other end of the central axis 2 is a fixed end 23, the limit end 21 and the fixed end 23 are respectively located on both sides of the mounting plate 52, the middle part of the central axis 2 is located in the through hole 520, and an annular wing plate 22 is provided in the middle part of the central axis 2, the annular wing plate 22 is detachably connected to the mounting plate 52, and the limit end 21 is rotatably connected to the transmission chuck 1.
[0056] Specifically, the annular wing plate 22 and the mounting plate 52 are both plate-shaped, and the contact surface is a plane. The annular wing plate 22 and the mounting plate 52 are tightly fitted by bolt fastening to achieve a better sealing connection between the annular wing plate 22 and the mounting plate 52. In addition, a sealing gasket can be arranged between the annular wing plate 22 and the mounting plate 52 to further ensure a better sealing connection effect between the annular wing plate 22 and the mounting plate 52.
[0057] The structure in which the mounting plate 52 and the central shaft 2 are separated reduces the processing difficulty and the production cost.
[0058] like Figure 7 As shown, an upper through hole 310 corresponding to the limiting end 21 is provided on the upper shell 3, and an upper annular boss 311 is provided on the upper shell 3 at the upper through hole 310, and the upper annular boss 311 is concentric with the upper through hole 310;
[0059] The upper annular boss 311 is sealed with the mounting plate 52 via the fourth sealing ring 312. The upper housing 3 is sealed with the central shaft 2 indirectly by the sealing connection between the upper annular boss 311 and the mounting plate 52. Specifically, a recessed groove for placing the fourth sealing ring 312 is provided on the end surface of the upper annular boss 311.
[0060] like Figure 8 As shown, a lower through hole 410 corresponding to the fixed end 23 is provided on the lower shell 4, and a lower annular boss 411 is provided on the lower shell 4 at the lower through hole 410, and the lower annular boss 411 is concentric with the lower through hole 410;
[0061] The lower shell 4 includes a fifth sealing ring 413, and the lower annular boss 411 is sealed and connected to the annular wing plate 22 through the fifth sealing ring 413. The lower shell 4 includes an integrally formed shell body 41, and the lower annular boss 411 is located around the lower through hole 410, and is an annular structure folded toward the inside of the shell body 41. The lower annular boss 411 is sealed and connected to the annular wing plate 22, thereby realizing the sealed connection between the lower shell 4 and the central shaft 2. Specifically, a recessed groove for placing the fifth sealing ring 413 is provided on the end surface of the lower annular boss 411.
[0062] In addition, if the rolling door machine has the function of detecting the door switch position, it can be an angle sensor set on the mounting plate 52, and the transmission structure between the detection end of the angle sensor and the transmission chuck 1 is sealed and connected to the upper shell 3, and the sealing method is the same as the sealing method at the gear shaft of the transmission gear 6, such as Figure 2 shown.
[0063] The installation process of the rolling door machine with waterproof and dustproof functions of this embodiment is as follows:
[0064] Assemble the mounting plate 52 and the central shaft 2 together, and install the drive motor 51 and the gear shaft of the transmission gear 6 on the mounting plate 52;
[0065] A controller 7 is installed on the lower housing 4;
[0066] The first sealing ring 412 and the fifth sealing ring 413 are assembled on the lower housing 4, and the fourth sealing ring 312 is assembled on the upper housing 3, and then the upper housing 3 and the lower housing 4 are sealed and connected, and the upper housing 3 and the lower housing 4 are fixed on the mounting plate 52. At this time, the gear shaft passes through the upper housing 3, the fourth sealing ring 312 is in contact and seal with the mounting plate 52, and the fifth sealing ring 413 is in contact and seal with the annular wing plate 22 of the central shaft 2;
[0067] A third sealing ring 61 is installed between the gear shaft and the upper housing 3 to seal the gear shaft and the upper housing 3, and then a transmission gear 6 is installed at the end of the gear shaft;
[0068] The transmission chuck 1 is mounted on the central shaft 2 and is connected to the transmission gear 6 to complete the assembly of the rolling door machine.
[0069] The rolling door machine of this embodiment is provided with a sealed housing, and a waterproof and dustproof sealing structure is added to the portion connected to the sealed housing, so that the electrical components are placed in a sealed space, achieving the IP34 waterproof and dustproof grade.
