The lens assembly and the screen assembly are respectively designed with a "concave" and a "convex" design to form a glue dispensing space, which can effectively improve glue overflow. However, when curing by UV light source, most of the glue cannot be exposed to the light and the glue curing rate is low. Therefore, a baking process must be added later, which not only increases the cost, but also easily causes damage to the screen and lens during baking. Utility Model Content

[0033] 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.
[0034] 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.
[0035] like Figure 1 As shown, the present disclosure provides a display module, which includes a screen structure 1, a lens structure 2 and an annular adhesive layer 3. The screen structure 1 includes a screen bracket 11 and a display 12, and the display 12 is mounted on the screen bracket 11. The lens structure 2 includes a lens barrel 21 and an optical component 22, and the optical component 22 is mounted in the lens barrel 21. The lens barrel 21 and the screen bracket 11 both have annular ends, and an annular space for accommodating the annular adhesive layer 3 is formed between the two annular ends. The annular space is connected to the external environment through an annular opening, and the annular adhesive layer 3 is formed by curing glue to connect the screen bracket 11 and the lens barrel 21.
[0036] It can be understood that by accommodating the annular space of the annular adhesive layer 3 between the annular ends of the screen bracket 11 and the lens barrel 21, the annular space is connected to the external environment through the annular opening. Therefore, after glue is dispensed in the annular space, the entire circle of glue can be irradiated and cured through the annular opening between the annular space and the external environment, thereby improving the problem of the glue not being able to contact the light source, which is beneficial to improving the glue curing rate, thereby eliminating the subsequent baking process, reducing costs and avoiding damage to the screen and lens.
[0037] It should be noted that the above glue is a UV thermosetting glue, which is cured when irradiated by a UV curing light source.
[0038] In addition, by setting up the annular space, a whole circle of glue is formed after glue dispensing. At this time, a circular UV curing light source can be used for parallel irradiation, so that the distance from the circular light source to the glue remains consistent, which helps to uniformly cure the glue and avoids deformation of the lens barrel 21 and the screen bracket 11 due to uneven curing of the whole circle of glue.
[0039] Further, refer to Figure 1 The above-mentioned optical component 22 includes an optical film material 221 and an optical lens 222. The number of the optical film material 221 and the optical lens 222 is set according to actual needs and is not specifically limited here.
[0040] Furthermore, the screen bracket 11 is provided with a through hole for the light emitted by the display 12 to irradiate the optical component 22. Figure 1 The screen bracket 11 includes a display mounting plate 111 and a connecting tube 112. The display mounting plate 111 is provided with a through hole in its thickness direction. The connecting tube 112 and the display 12 are respectively located on both sides of the display mounting plate 111 in the thickness direction. The connecting tube 112 has the above-mentioned annular end.
[0041] For example, in a specific implementation, referring to Figure 1 The display mounting plate 111 and the connecting tube 112 can be an integrally formed structure, which can reduce the number of parts and reduce the difficulty of assembly. Alternatively, the display mounting plate 111 and the connecting tube 112 can also be a split structure, connected by means such as screws, bonding, etc. to form a screen bracket.
[0042] In addition, the display 12 is fixed to the screen bracket 11 by adhesive, that is, the display 12 is connected to the display mounting plate 111 by bonding.
[0043] Reference Figure 2 In some embodiments, the end surface of at least one annular end facing the other annular end is an annular plane perpendicular to the axial direction of the lens barrel 21 .
[0044] That is to say, the entire end surface of the annular end is an annular plane, so when the screen structure 1 and the lens structure 2 are actively aligned and assembled, there will be no obstruction or interference when the position of the screen bracket 11 and / or the lens barrel 21 is adjusted, which facilitates the adjustment of the relative position of the screen bracket 11 and the lens barrel 21.
[0045] Specifically, during adjustment, the screen support 11 can move along the x, y, and z directions relative to the lens barrel 21, and the lens barrel 21 can move along the x, y, and z directions relative to the screen support 11. The z direction is the axis direction of the lens barrel 21, and the x and y directions are directions perpendicular to the axis of the lens barrel 21. Both the x and y directions are in an adjustment plane, and the translation in the adjustment plane can be decomposed into two components in the x and y directions.
[0046] For example, refer to Figure 2 The end surface of each annular end facing the other annular end is an annular plane perpendicular to the axial direction of the lens barrel 21. The annular space is formed between the two annular planes, so that the relative position of the screen bracket 11 and the lens barrel 21 can be adjusted easily.
[0047] Furthermore, the distance between the two annular planes is 0.3 mm-0.5 mm.
[0048] In addition, illustratively, in a specific implementation, referring to Figure 2 , the radial width of one of the two annular planes is greater than the radial width of the other annular plane.
[0049] That is to say, the radial widths of the two annular planes are different. After the glue is dispensed between the two annular planes, on the one hand, a long irradiation path can be avoided between the two annular planes, and the light source can be used to irradiate the side of the annular plane with a smaller radial width, which is conducive to fully irradiating the glue and improving the curing efficiency of the glue. On the other hand, the annular plane with a larger radial width can also serve as a glue overflow space.
[0050] Reference Figure 3 In some embodiments, the annular plane has an annular glue dispensing area, and in the radial direction of the annular plane, the width of the annular plane is greater than 1.5 times the width of the annular glue dispensing area. The annular glue dispensing area is used for glue dispensing.
[0051] That is to say, the width of the annular plane is set to be larger than the width of the annular glue dispensing area. In this way, when dispensing glue, the area of the annular plane except the annular glue dispensing area can be used as a glue overflow space to prevent the glue from overflowing to the outer side of the annular end in the radial direction of the annular plane, thereby improving the aesthetics.
[0052] For example, in a specific implementation, referring to Figure 3 , the annular planes on the two annular ends all have annular glue-dispensing areas. Alternatively, only the annular plane of the annular end of the lens barrel 21 has an annular glue-dispensing area or only the annular plane of the annular end of the screen bracket 11 has an annular glue-dispensing area.
[0053] In some embodiments, the annular end of the screen bracket 11 has a first annular inclined surface 101 inclined relative to its axial direction, and an annular space is formed between the first annular inclined surface 101 and the annular end of the lens barrel 21 to form a trumpet-shaped opening connected to the external environment.
[0054] It can be understood that by providing the first annular inclined surface 101, an annular space is formed between the first annular inclined surface 101 and the annular end of the lens barrel 21 to communicate with the external environment. In this way, when curing the glue, the light entry area can be increased, that is, the area of the opening is increased, which is convenient for the light source to irradiate the glue, thereby facilitating the curing rate of the glue and shortening the curing time.
[0055] In other embodiments, the annular end of the lens barrel 21 may have a second annular inclined surface inclined relative to its axial direction, and an annular space is formed between the second annular inclined surface and the annular end of the screen bracket 11 to form a trumpet-shaped opening connected to the external environment.
[0056] It can be understood that by setting the second annular inclined surface, an annular space is formed between the second annular inclined surface and the annular end of the screen bracket 11 to connect to the external environment. In this way, when the glue is irradiated and cured, the light intake area is increased, that is, the area of the opening is increased, which is convenient for the light source to irradiate the glue, thereby facilitating the curing rate of the glue and shortening the curing time.
[0057] Alternatively, the annular end of the screen bracket 11 may have a first annular inclined surface inclined relative to its axial direction; and the annular end of the lens barrel may have a second inclined surface inclined relative to its axial direction. In this way, a trumpet-shaped opening that is connected to the external environment through an annular space formed between the first annular inclined surface and the second annular inclined surface can be further opened compared to the first two cases, thereby increasing the light-incoming area, further improving the curing rate of the glue, and shortening the curing time.
[0058] For example, in a specific implementation, referring to Figure 4 Only the annular end of the screen bracket 11 has a first annular inclined surface 101 inclined relative to its axial direction.
[0059] Reference Figure 5 and Figure 6 In some embodiments, the annular end of the screen bracket 11 has a first annular bonding surface, the annular end of the lens barrel 21 has a second annular bonding surface, and the annular bonding layer 3 is disposed between the first annular bonding surface and the second annular bonding surface.
[0060] For example, in a specific implementation, a first annular glue overflow groove 102 is provided on the annular end of the screen bracket 11, and the first annular glue overflow groove 102 is located on the radial outer side of the first annular bonding surface of the annular end. Alternatively, a second annular glue overflow groove (not shown in the figure) is provided on the annular end of the lens barrel 21, and the second annular glue overflow groove is located on the radial outer side of the second annular bonding surface of the annular end. Alternatively, a first annular glue overflow groove 102 is provided on the annular end of the screen bracket 11, and the first annular glue overflow groove 102 is located on the radial outer side of the first annular bonding surface of the annular end; and at the same time, a second annular glue overflow groove is provided on the annular end of the lens barrel 21, and the second annular glue overflow groove is located on the radial outer side of the second annular bonding surface of the annular end.
[0061] It can be understood that by providing the first annular glue overflow groove 102 and / or the second annular glue overflow groove, the glue overflow space is increased. On the one hand, the overflowed glue can be collected to avoid excessive glue overflow and affect the aesthetics; on the other hand, more glue can be allowed to be used to avoid the problem of sealing failure caused by insufficient glue. In this case, the distance between the glue in the annular glue overflow groove and the light source is shortened, which can reduce the transmission path of light and increase the curing rate of the glue.
[0062] For example, in a specific implementation, the first annular glue overflow groove 102 is provided on the annular end of the connecting tube 112 of the screen bracket 11. Figure 5 , the cross section of the first annular glue overflow groove 102 is U-shaped. Figure 6 The first annular glue overflow groove 102 penetrates the outer peripheral surface of the annular end in the radial direction of the annular plane, so that the gap between the two annular ends can be increased to facilitate the incidence of UV light.
[0063] Furthermore, in some embodiments, the annular end of the screen bracket 11 has a first annular bonding surface, and the annular end of the lens barrel 21 has a second annular bonding surface.
[0064] Further, the annular end of the screen bracket 11 has the above-mentioned first annular inclined surface 101, and the first annular inclined surface 101 is located outside the first annular bonding surface. Alternatively, the annular end of the lens barrel 21 has a second annular inclined surface, and the second annular inclined surface is located outside the second annular bonding surface. Alternatively, the annular end of the screen bracket 11 has the above-mentioned first annular inclined surface 101, and the annular end of the lens barrel 21 has a second annular inclined surface.
[0065] For example, in a specific implementation, referring to Figure 4 The annular end of the screen bracket 11 has a first annular bonding surface, the annular end of the lens barrel 21 has a second annular bonding surface, the annular end of the screen bracket 11 has the above-mentioned first annular inclined surface 101, and the first annular inclined surface 101 is located on the outside of the first annular bonding surface.
[0066] It should be noted that the above-mentioned first annular bonding surface and the second annular bonding surface are parallel or approximately parallel, so that when the screen bracket 11 and the lens barrel 21 are squeezing the glue, the forces applied to the glue by the two are opposite, thereby reducing the components of force in the x and y directions, and avoiding large slippage of the screen bracket 11 and the lens barrel 21 when squeezing the glue and the glue is not cured.
[0067] The present disclosure also provides a VR glasses, which include the above-mentioned display module. The VR glasses have the technical effects of the display module in the above-mentioned embodiment, which will not be repeated here.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
