DETAILED DESCRIPTION

[0044] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0045] See also Figures 1 to 3 , Figure 1 The structure diagram of the glass bracket assembly in one embodiment of the present application is shown. Figure 2 and Figure 3 They respectively indicated Figure 1 The structure shown is an enlarged view of two different examples at A. An embodiment of the present application provides a glass bracket assembly, which includes: a glass 11, a bracket 12 and an injection molding glue 13. The bracket 12 includes a bracket portion 121 and a retaining portion 122 connected to the bracket portion 121. A slot 1220 extending toward the bracket portion 121 is formed on the side of the retaining portion 122 away from the bracket portion 121, and the edge of the glass 11 is inserted into the slot 1220. A sealing portion 123 is provided on the bracket 12, which is circumferentially arranged around the notch of the slot 1220. The sealing portion 123 is used to abut and cooperate with the molding mold of the glass bracket assembly. When the sealing portion 123 abuts against the molding mold, the notch of the slot 1220 is in a closed state. The injection molding glue 13 is filled in the slot 1220, and the edge of the glass 11 is integrally injection molded with the retaining portion 122 by the injection molding glue 13.

[0046] The above-mentioned glass bracket assembly, since the bracket 12 is provided with a sealing portion 123 circumferentially arranged around the notch of the slot 1220, during the production process, after the sealing portion 123 abuts against the molding mold, it can play a role in accurately positioning the bracket 12 and the glass 11, and can make the notch of the slot 1220 in a completely closed state, and then the glass 11 and the bracket 12 are made into a whole through the PU edging one-piece injection molding process, thereby achieving the advantages of reducing process steps, improving product performance strength and precision, and having the advantages of short production cycle and high yield; in addition, the assembly of the bracket 12 and the glass 11 adopts one-piece injection molding, which can eliminate the gluing and curing process and greatly reduce the manufacturing cost.

[0047] In some embodiments, the material of the injection molding glue 13 includes but is not limited to thermoplastic elastomer (Thermoplastic Elastomer, TPE), polyurethane (poly urethane, PU), etc., which can be flexibly selected and set according to actual conditions, and this embodiment does not make any specific limitations here.

[0048] See also Figure 1 , Figure 4 and Figure 5 In a specific embodiment, the holding portion 122 includes two clamping plates 1221 arranged at a relative interval. One end of the two clamping plates 1221 is connected to the bracket portion 121, and the two clamping plates 1221 and the bracket portion 121 enclose a slot 1220. The sealing portion 123 includes two first sealing strips and two second sealing strips. The two first sealing strips are arranged at the edges of the clamping plates 1221, and the two second sealing strips are arranged at opposite sides of the bracket portion 121. One end of the two first sealing strips is connected by one of the second sealing strips, and the other end of the two first sealing strips is connected by another second sealing strip. In this way, the two first sealing strips and the two second sealing strips are connected end to end in sequence, so that the sealing portion 123 is a closed annular structure, so that the sealing portion 123 is arranged circumferentially around the notch of the slot 1220. In the production process, after the sealing portion 123 abuts against the forming mold, it can not only accurately position the bracket 12 and the glass 11, but also make the notch of the slot 1220 in a completely closed state.

[0049] It should be noted that, in one embodiment, the "sealing portion 123" may be "a part of the bracket 12", that is, the "sealing portion 123" is manufactured integrally with the "other parts of the bracket 12"; it may also be an independent component that is separable from the "other parts of the bracket 12", that is, the "sealing portion 123" can be manufactured independently and then combined with the "other parts of the bracket 12" into a whole. In another embodiment, the "first sealing strip" may be "a part of the retaining portion 122", that is, the "first sealing strip" is manufactured integrally with the "other parts of the retaining portion 122"; it may also be an independent component that is separable from the "other parts of the retaining portion 122", that is, the "first sealing strip" can be manufactured independently and then combined with the "other parts of the retaining portion 122" into a whole. In another embodiment, the "second sealing strip" can be "a part of the bracket portion 121", that is, the "second sealing strip" and the "other parts of the bracket portion 121" are manufactured as one piece; it can also be an independent component separable from the "other parts of the bracket portion 121", that is, the "second sealing strip" can be manufactured independently and then combined with the "other parts of the bracket portion 121" into a whole.

[0050] In this embodiment, the sealing portion 123, the holding portion 122 and the bracket portion 121 are, for example, an integrated structure. In addition, the bracket 12 can be made of either a metal material or a non-metal material. As an example, the bracket 12 is made of a plastic material and is integrally injection molded; as another example, the bracket 12 is made of a metal material and is integrally molded by die casting or sheet metal integrally molded.

[0051] In addition, the cross-sectional profile of the sealing portion 123 along its circumferential direction includes but is not limited to a triangle (such as Figure 2 As shown), arc (as Figure 3 As shown in the figure), rectangle, pentagon and other regular shapes and other irregular shapes, which can be flexibly adjusted and set according to actual needs.

[0052] In some embodiments, see Figure 1 and Figure 2 The sealing part 123, the holding part 122 and the bracket part 121 are an integrated structure. The bracket 12 is a plastic frame. The cross-sectional profile of the sealing part 123 along its circumferential direction is triangular, and the tip of the sealing part 123 abuts against the forming mold. In this way, when the sealing part 123 abuts against the forming mold, since the cross-sectional profile of the sealing part 123 along its circumferential direction is triangular, the sealing part 123 is easily deformed by force and squeezed, which is convenient for interference with the forming mold, thereby having better sealing performance.

[0053] When the tip of the sealing part 123 contacts the molding die, the height of the sealing part 123 protruding from the end surface of the holding part 122 can affect the interference with the molding die. When the height of the sealing part 123 protruding from the surface of the holding part 122 is greater, the interference between the sealing part 123 and the molding die is greater, thereby enhancing the sealing performance; conversely, when the height of the sealing part 123 protruding from the end surface of the holding part 122 is smaller, the interference between the sealing part 123 and the molding die is smaller.

[0054] Of course, as some optional solutions, when the bracket 12 is a plastic part, the cross-sectional profile of the sealing portion 123 along its circumferential direction can also be set to be arc-shaped. Compared with the method of setting the cross-sectional profile to be arc-shaped, when the cross-sectional profile is set to be triangular, it has better sealing performance.

[0055] In some embodiments, see Figure 2 , the distance h1 between the tip of the sealing portion 123 and the surface of the holding portion 122 includes but is not limited to 0.1mm≤h1≤0.5mm, specifically 0.1mm, 0.3mm or 0.5mm, etc. In addition, the angle a of the tip of the sealing portion 123 is 20°≤a≤60°, specifically 20°, 30°, 40°, 50° or 60°. In addition, the bottom width b of the sealing portion 123 is 0.3mm≤b≤1.5mm, specifically 0.3mm, 0.5mm, 0.8mm, 1mm or 1.5mm, etc.

[0056] Based on the above embodiment, the tip of the sealing portion 123 is chamfered to form a rounded corner. In this way, when the tip of the sealing portion 123 contacts the molding die, the rounded corner contacts the molding die, which can reduce the damage to the molding die. Optionally, the radius R1 of the rounded corner includes but is not limited to 0 <R1≤0.1mm。

[0057] In some embodiments, refer to Figure 1 and Figure 3 , the sealing portion 123, the holding portion 122, and the bracket portion 121 are an integrated structure. The bracket 12 is a metal frame, and the cross-sectional profile of the sealing portion 123 in its circumferential direction is arc-shaped. In this way, when the sealing portion 123 abuts against the molding die, due to the relatively high hardness of the material of the metal frame and the arc-shaped cross-sectional profile of the sealing portion 123 in its circumferential direction, it not only has good sealing performance but also can reduce the damage to the molding die, thus avoiding the defect that the sealing performance is weakened due to the contact between the sharp corners and the molding die.

[0058] Based on the foregoing embodiments, taking the surface of the holding portion 122 as the reference surface, the maximum height h2 of the outer surface of the sealing portion 123 relative to the reference surface includes but is not limited to 0.05 mm ≤ h2 ≤ 0.35 mm, specifically, for example, 0.05 mm, 0.1 mm, 0.2 mm, or 0.35 mm, etc. In addition, the radius R2 of the arc includes but is not limited to 1 mm < R2 ≤ 5 mm, such as 1 mm, 3 mm, or 5 mm, etc.

[0059] In some embodiments, the wall thickness W of the slot 1220 includes but is not limited to 1 mm < W ≤ 4 mm, specifically, for example, 1 mm, 2 mm, 3 mm, or 4 mm, etc. Herein, the wall thickness of the slot 1220 is also the thickness of the clamping plate 1221. When the wall thickness W of the slot 1220 is greater than or equal to 1 mm, the structural strength is relatively large, which can ensure the structural strength of the connection with the glass 11 and enhance the stability; when the wall thickness W of the slot 1220 is less than or equal to 4 mm, it can avoid material waste caused by the excessive wall thickness W of the slot 1220.

[0060] Refer to Figure 4 and Figure 5 , in some embodiments, at least one reinforcing rib 1222 is provided on the inner wall of the slot 1220. The reinforcing rib 1222 extends from one end of the slot 1220 close to the bracket portion 121 towards the other end. Specifically, at least one reinforcing rib 1222 is provided on the side surfaces of the two clamping plates 1221 facing each other. In this way, the reinforcing rib 1222 can not only increase the structural strength of the holding portion 122 but also play a role in clamping the glass 11, thereby improving the structural stability of the combination of the glass 11 and the holding portion 122.

[0061] Specifically, a first guiding surface 1223 is provided at the end of the reinforcing rib 1222 away from the bracket portion 121. Optionally, the first guiding surface 1223 includes but is not limited to a bevel surface or an arc surface, etc., as long as it can play a guiding role for the edge of the glass 11. During the process of inserting the edge of the glass 11 into the slot 1220, when the edge of the glass 11 contacts the first guiding surface 1223, it is beneficial to smoothly insert the edge of the glass 11 into the slot 1220 and reduce the collision and friction damage.

[0062] See also Figure 6 In some embodiments, the retaining portion 122 is provided with at least one through hole 1224. The injection molding 13 is provided with a first protrusion 131 filled in the through hole 1224. And / or, the inner wall of the slot 1220 is provided with at least one second protrusion, and the second protrusion is embedded and fixed inside the injection molding 13. In this way, after integral injection molding, the first protrusion 131 of the injection molding 13 is also fixed in the through hole 1224, and / or the second protrusion is embedded and fixed inside the injection molding 13, so as to enhance the combination stability of the injection molding 13 and the retaining portion 122, and prevent the retaining portion 122 from loosening from the edge of the glass 11.

[0063] See also Figure 6 In a specific embodiment, each clamping plate 1221 is provided with at least two through holes 1224 . At least two first protrusions 131 are respectively provided on opposite sides of the injection molding 13 , and each first protrusion 131 is correspondingly fixed in each through hole 1224 .

[0064] See also Figures 7 to 16 , Figures 7 to 16 It is a structural diagram showing different states according to the molding process sequence of the glass bracket assembly.

[0065] For example, see Fig. 9 In some embodiments, an embodiment of the present application provides a molding mold for manufacturing the glass bracket assembly of any of the above embodiments, and the molding mold includes a lower mold 20 and an upper mold 30.

[0066] The lower mold 20 is provided with a first pressing portion 21 for abutting against the first side surface of the glass 11. One side of the first pressing portion 21 is provided with a first recessed portion 211 that is recessed in a direction away from the first side surface. In addition, the upper mold 30 is provided with a second pressing portion 31 for abutting against the second side surface of the glass 11. One side of the second pressing portion 31 is provided with a second recessed portion 311 that is recessed in a direction away from the second side surface.

[0067] When the upper mold 30 and the lower mold 20 are closed, the first pressing portion 21 abuts against the first side surface, the second pressing portion 31 abuts against the second side surface, and the first recessed portion 211 and the second recessed portion 311 cooperate to form a groove 40 that is adapted to the shape of the retaining portion 122; that is, the first recessed portion 211 extends to the edge position of one side of the first pressing portion 21, and the second recessed portion 311 extends to the edge position of one side of the second pressing portion 31, so that the retaining portion 122 can be inserted into the groove 40, and the sealing portion 123 is sealingly abutted against the inner wall of the groove 40.

[0068] When the molding mold of the above-mentioned glass holder assembly is in use, after the retaining part 122 is inserted into the groove 40, the edge of the glass 11 is correspondingly inserted into the slot 1220 of the retaining part 122. Since the sealing part 123 is sealed and abutted against the inner wall of the groove 40, the notch of the slot 1220 is in a closed state, and has good sealing performance. Furthermore, after the injection molding glue 13 is injected into the slot 1220, it can effectively prevent the injection molding glue 13 from overflowing and prevent flash defects, thereby effectively improving product quality and production efficiency, thereby achieving the advantages of reducing process steps, improving product performance strength and precision, and having a short production cycle and a high yield rate.

[0069] In some embodiments, in order to inject the injection molding glue 13 into the interior of the slot 1220, an injection hole is provided on the upper mold 30 and / or the lower mold 20. The specific opening position of the injection hole can be flexibly adjusted and set according to actual needs, as long as the injection molding glue 13 can enter the interior of the slot 1220 through the injection hole after the upper mold 30 and the lower mold 20 are closed.

[0070] See also Fig.10 and Fig.11 In one embodiment, the lower mold 20 further includes a first seal 22 mounted on the first pressing portion 21. The first seal 22 is arranged at the periphery of the first recess 211, and the first seal 22 abuts against the first side surface. In addition, the upper mold 30 further includes a second seal 32 mounted on the second pressing portion 31. The second seal 32 is arranged at the periphery of the second recess 311, and the second seal 32 abuts against the second side surface. In this way, the first seal 22 plays a sealing role, which can prevent the injection glue 13 inside the slot 1220 from overflowing through the gap between the first pressing portion 21 and the first side surface during the injection molding process; in addition, the second seal 32 plays a sealing role, which can prevent the injection glue 13 inside the slot 1220 from overflowing through the gap between the second pressing portion 31 and the second side surface, thereby improving the product processing quality.

[0071] In some embodiments, the first seal 22, for example, extends along the edge of the first recess 211 and is arranged at the periphery of the first recess 211, so that the first seal 22 is arranged circumferentially around the notch of the slot 1220, which is conducive to making the socket of the slot 1220 in a completely closed state. Optionally, the first seal 22 includes but is not limited to a sealing strip or a sealing block, etc. Similarly, the second seal 32, for example, extends along the edge of the second recess 311 and is arranged at the periphery of the second recess 311, so that the second seal 32 is arranged circumferentially around the notch of the slot 1220, which is conducive to making the socket of the slot 1220 in a completely closed state. Optionally, the second seal 32 includes but is not limited to a sealing strip or a sealing block, etc.
