[0032] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0034] In the related art, when an irregular glass (such as a windshield of a vehicle) is coated by a coating device, the coating of the glass is uneven due to the irregular shape of the glass.

[0035] In order to solve the above technical problems, the present application provides a coating fixing frame. Figure 1 , Figure 1 Schematic diagram of a coating fixture provided in some embodiments of the present application. The coating fixture 1 may include a coating base 11 and a mounting member 12.

[0036] A through coating opening 111 may be formed on the coating base 11. Thus, when the glass to be coated is placed on the coating fixing frame 1, the coating base 11 may be prevented from blocking the glass during coating.

[0037] Exemplarily, the coating port 111 may be disposed in the central area of ​​the coating base 11. The coating port 111 may be circular, elliptical, rectangular, etc. The shape of the coating port 111 may be designed according to the shape of the glass, which is not limited in the present application.

[0038] The mounting member 12 can be used to support the glass to be coated. The mounting member 12 may include a connecting seat 121 and a sliding seat 122. The connecting seat 121 may be arranged on the top side of the coating base 11 and around the edge of the coating port 111. The "top side" of the coating base 11 refers to the top of the coating base 11. By arranging the connecting seat 121 on the top side of the coating base 11, the area of ​​the coated glass to be coated can be coated through the coating port 111.

[0039] One end of the sliding seat 122 can be slidably connected to the connecting seat 121 along a direction parallel to the central axis of the coating port 111. The other end of the sliding seat 122 can extend in a direction close to the central axis of the coating port 111. Specifically, the sliding seat 122 can be arranged on a side of the connecting seat 121 close to the coating port 111, and the sliding seat 122 can be slidably matched with the connecting seat 121, and the sliding seat 122 is used to carry the glass to be coated. Therefore, through the sliding cooperation between the sliding seat 122 and the connecting seat 121, the sliding seat 122 can change the position of the glass to be coated on the coating base 11, and the placement angle thereof can be adjusted, so as to improve the uniformity of the coating of the glass to be coated, and make the wear resistance, light transmittance and other properties of the coated glass better. At the same time, the coating fixing frame 1 can be applied to the coating of irregular glass, which is conducive to improving the versatility and reliability of the coating of the coating fixing frame 1.

[0040] According to the coating fixture 1 of the embodiment of the present application, by setting the connecting seat 121 at the edge of the coating port 111 and making the sliding seat 122 slidably cooperate with the connecting seat 121, the sliding seat 122 can slide in a direction parallel to the central axis of the coating port 111, so that the placement angle of the glass to be coated set on the sliding seat 122 can be changed, which is conducive to improving the uniformity of the coating of the glass to be coated, and improving various properties of the glass at the coating port 111. At the same time, the coating fixture 1 can be applied to the coating of irregular glass, which is conducive to improving the versatility and reliability of the coating of the coating fixture 1.

[0041] See also Figure 1 and Figure 2 , Figure 2 A three-dimensional diagram of a mounting member provided for some embodiments of the present application. In some embodiments, a first slide groove 1211 may be formed on the connecting seat 121. The first slide groove 1211 may extend in a direction parallel to the central axis of the coating port 111. A sliding portion 1221 may be provided on the sliding seat 122. The sliding portion 1221 may be slidably engaged with the first slide groove 1211. Thus, through the engagement of the sliding portion 1221 with the first slide groove 1211, the sliding portion 1221 carrying the glass to be coated may adjust the placement angle of the glass to be coated, which is simple and easy to operate.

[0042] It should be noted that the sliding seat 122 may be provided with a sliding groove, and the connecting seat 121 may be provided with a component that matches the sliding groove, and this application does not limit this.

[0043] Please continue reading Figure 1 and Figure 2In some embodiments, the mounting member 12 may include a plurality of connection seats 121 and a plurality of sliding seats 122. The plurality of connection seats 121 may be arranged at intervals around the edge of the coating port 111. The connection seat 121 may be provided with a first slide groove 1211. Specifically, the plurality of connection seats 121 are arranged at circumferential intervals around the coating port 111. Among them, the plurality of connection seats 121 may be arranged at even intervals, or may be arranged according to the shape of the glass to be coated. For example, when the glass to be coated is a windshield, the plurality of connection seats 121 may be arranged according to the shape of the windshield.

[0044] The plurality of connecting seats 121 may correspond one-to-one to the plurality of sliding seats 122 , that is, one connecting seat 121 corresponds to one sliding seat 122 .

[0045] Thus, by setting a plurality of spaced connection seats 121, and making a plurality of sliding seats 122 matched with the plurality of connection seats 121 to carry different regions of the glass to be coated, when different sliding seats 122 slide in a direction parallel to the central axis of the coating port 111, the positions of different regions of the glass to be coated can be adjusted, so that the position of the sliding seat 122 can be adjusted according to the coating needs, so that the coating uniformity of the glass to be coated can be better. At the same time, it can also be applicable to glass of different shapes, which is conducive to improving the versatility of the coating fixing frame 1.

[0046] For example, the side of the sliding seat 122 away from the coating port 111 can extend in a direction parallel to the central axis of the coating port 111, so that the sliding seat 122 can be formed into an "L" shape. In this way, the connection area between the sliding seat 122 and the connecting seat 121 can be increased, so that the sliding of the sliding seat 122 can be more stable and reliable.

[0047] Please continue reading Figure 1 and Figure 2 In some embodiments, the number of the first slide grooves 1211 may be multiple, and the multiple first slide grooves 1211 may be spaced apart in the direction surrounding the coating port 111. The sliding portion 1221 may include multiple sliding portions 1221 arranged in a one-to-one correspondence with the multiple first slide grooves 1211, and the sliding portion 1221 may be slidably matched with the first slide groove 1211. Specifically, one sliding portion 1221 may correspond to one first slide groove 1211, one sliding portion 1221 may be inserted into the first slide groove 1211, and the sliding portion 1221 may slide along the extension direction of the first slide groove 1211. Among them, "multiple" means that the number of the first slide grooves 1211 is two or more, and the number of the sliding portions 1221 is two or more.

[0048] Thus, the sliding seat 122 can be more stable when sliding through the cooperation of the plurality of sliding parts 1221 and the plurality of first slide grooves 1211. At the same time, the position of the sliding part 1221 in the first slide groove 1211 can be adjusted as needed, so that the position of the sliding seat 122 can be changed, so that there can be an angle between the sliding seat 122 and the connecting seat 121, and then the adjustable range of the sliding seat 122 can be increased, so that the range of the coating fixing frame 1 to adjust the glass to be coated can be enlarged, so that the coating uniformity of the glass to be coated can be better.

[0049] Exemplarily, the sliding portion 1221 is inserted into the first sliding groove 1211 , one end of the sliding portion 1221 is connected to the sliding seat 122 , and the size of the other end is larger than that of the first sliding groove 1211 , which can prevent the sliding portion 1221 from falling off during the sliding process.

[0050] It should be noted that the sliding portion 1221 and the sliding seat 122 may be detachably connected, which is convenient for replacing and repairing the sliding seat 122, and is conducive to improving the maintainability of the coating fixing frame 1. For example, it can be connected by means of a snap connection, a fastener connection, a latch connection, etc. The sliding portion 1221 and the sliding seat 122 may also be fixedly connected, which can improve the assembly efficiency of the coating fixing frame 1.

[0051] Please continue reading Figure 1 and Figure 2 In some embodiments, the width of the first slide groove 1211 may be greater than the width of the portion of the sliding portion 1221 located in the first slide groove 1211. Thus, the restriction of the first slide groove 1211 on the sliding portion 1221 in the width direction can be reduced, so that the sliding portion 1221 can slide in the width direction of the first slide groove 1211, thereby adjusting the position of the sliding seat 122 in the width direction of the first slide groove 1211, which is conducive to expanding the adjustable range of the coating fixing frame 1 for the position of the glass to be coated.

[0052] Please continue reading Figure 1 and Figure 2 In some embodiments, the connection seat 121 can be slidably connected to the coating base 11 in a direction close to or away from the coating port 111. Therefore, through the sliding cooperation between the connection seat 121 and the coating base 11, the connection seat 121 as a whole can slide in a direction close to or away from the coating port 111, so that the position of the connection seat 121 can be adjusted according to the size of the glass to be coated. For example, when the size of the glass to be coated is small, the connection seat 121 can be slid in a direction close to the coating port 111. When the size of the glass to be coated is large, the connection seat 121 can be slid in a direction away from the coating port 111, so that the coating fixing frame 1 can be applicable to glasses of different sizes, which is conducive to improving the versatility of the coating fixing frame 1.

[0053] Please continue reading Figure 1 and Figure 2 In some embodiments, a third slide groove 1212 may be formed on the connection seat 121. The third slide groove 1212 may extend in a direction close to or away from the coating port 111. A matching piece 112 is provided on the coating base 11, and the matching piece 112 is slidably matched with the third slide groove 1212. Thus, the connection seat 121 can slide in a direction close to or away from the coating port 111 through the third slide groove 1212 and the matching piece 112. The matching method is simple and easy to assemble, which is conducive to reducing the manufacturing cost of the coating fixture 1.

[0054] It should be noted that a slide groove may be provided on the coating base 11 , and a component matching with the slide groove may be provided on the connecting base 121 .

[0055] In some embodiments, the connecting seat 121 can be formed in a ring shape. A plurality of second slide grooves can be formed on the connecting seat 121. The second slide groove can extend in a direction parallel to the central axis of the coating port 111. A plurality of second slide grooves can be arranged at intervals around the coating port 111. The sliding seat 122 can slidably cooperate with the second slide groove. Specifically, the number of the connecting seat 121 is one, and the connecting seat 121 can be arranged around the coating port 111. A plurality of second slide grooves arranged at intervals can be provided on one side of a connecting seat 121 close to the coating port 111, and a plurality of sliding seats 122 correspond one to one with the plurality of second slide grooves.

[0056] Therefore, the connecting seat 121 can be provided with a plurality of sliding seats 122 for adjusting the placement angle of the glass to be coated, so that the glass to be coated can be coated evenly. At the same time, it can also be applied to irregularly shaped glass such as windshields, so that the irregularly shaped glass can be placed at an adjusted angle to make the overall coating more uniform, thereby facilitating the versatility of the coating fixing frame 1.

[0057] See also Figure 3 and Figure 4 , Figure 3 A schematic diagram of a coated umbrella stand provided in some embodiments of the present application, Figure 4 Schematic diagram of the connection between the coating frame and the coating fixing frame provided in some embodiments of the present application. The coating umbrella stand 104 provided in the embodiment of the present application may include a fixing bracket 2, a coating frame 3 and the above-mentioned coating fixing frame 1. The fixing bracket 2 may be located above the coating fixing frame 1.

[0058] Exemplarily, in the central axial direction of the coating port 111, there is a distance between the fixing bracket 2 and the coating fixing bracket 1. Thus, it is possible to prevent the fixing bracket 2 from affecting the placement of the glass to be coated on the coating fixing bracket 1.

[0059] The coating frame 3 can be connected to the fixing bracket 2. The coating frame 3 can be located on a side of the coating fixing bracket 1 away from the fixing bracket 2 and detachably connected to the coating base 11. Therefore, when it is necessary to replace a different glass to be coated, the coating base 11 can be removed from the coating frame 3, which is conducive to reducing the difficulty of using the coating umbrella stand 104 and improving the coating efficiency of the coating umbrella stand 104. At the same time, it is also convenient to repair the coating umbrella stand 104.

[0060] Please continue reading Figure 3 and Figure 4 , the coating frame 3 is detachably connected to the fixed bracket 2. Thus, the coating bracket is indirectly detachably connected to the fixed bracket 2, which is conducive to reducing the difficulty of using the coated umbrella stand 104, and can also replace different glasses to be coated more quickly, which is conducive to improving the coating efficiency of the coated umbrella stand 104. At the same time, it is also convenient to improve the maintainability of the coated umbrella stand 104.

[0061] Please continue reading Figure 3 and Figure 4 In some embodiments, the coated umbrella stand 104 may further include a connector 4. One end of the connector 4 is detachably connected to the fixed bracket 2, and the other end of the connector 4 is detachably connected to the coated frame 3. Thus, the connector 4 can realize a detachable connection between the fixed bracket 2 and the coated frame 3, which can further reduce the difficulty of using and disassembling the coated umbrella stand 104, and can also further improve the maintainability of the coated umbrella stand 104.

[0062] Please continue reading Figure 3 and Figure 4 In some embodiments, the coated umbrella stand 104 may further include a connecting bolt 31 and a connecting nut 32. The connecting bolt 31 is connected to the coated frame 3.

The head of the bolt abuts against the side of the connecting plate 42 away from the coated frame 3. The rod of the bolt is inserted into the notch and cooperates with the nut thread. Thus, through the cooperation between the connecting plate 42 and the connecting bolt 31, the coated frame 3 and the fixed umbrella stand can be detachably connected, the connection method is simple, and the assembly of the coated umbrella stand 104 is convenient, and it is also beneficial to reduce the manufacturing cost of the coated umbrella stand 104.

[0063] Exemplarily, the connection notch 41 may be a notch on the connection plate 42 , and the connection bolt 31 may directly enter the connection notch 41 from a side of the connection plate 42 .

[0064] See also Figure 4 and Figure 5 , Figure 5Schematic diagram of a coating frame provided in some embodiments of the present application. Exemplarily, the coating frame 3 has an opening 33 corresponding to the coating port 111, and a boss 34 extending toward the central axis of the opening 33 is provided on the side wall of the opening 33, and the coating base 11 can be placed on the boss 34. This arrangement can be pre-positioned with the coating base 11 through the boss 34, and then the coating base 11 is fixed to the coating frame 3 by fasteners.

[0065] See also Figure 6 , Figure 6 Schematic diagram of the connection between the fixed bracket and the connecting member provided for some embodiments of the present application. The fixed bracket 2 may include a mounting ring 21 and a plurality of connecting rods 22. The connecting rod 22 is connected to the mounting ring 21 and extends radially along the mounting ring 21, and the plurality of connecting rods 22 are spaced apart in the circumferential direction of the mounting ring 21. A plurality of mounting holes 221 may be provided on the connecting rod 22. The plurality of mounting holes 221 are spaced apart in the extension direction of the connecting rod 22.
