DETAILED DESCRIPTION

[0034] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0036] A projector with a metal shell has a good appearance, making the overall product visually more advanced. However, a pure metal shell structure needs to ensure structural strength and has certain requirements on the thickness of the shell structure, which will lead to a higher cost of the shell structure. In order to ensure the metal effect of the appearance of the smart projector, the existing smart projector-type whole machine has a shell structure with a metal texture. Generally, the lower shell adopts a plastic structure and the upper shell adopts a partial metal structure. Therefore, the formed shell structure has a metal appearance at a specific viewing angle, while the plastic texture can still be seen at other viewing angles, affecting the aesthetics of the product.

[0037] In order to solve the above technical problems, an embodiment of the present application provides a projector housing, the overall appearance of which presents a metallic texture, and has a low cost and a light weight.

[0038] Specifically, Figures 1 to 12 As shown, the projector housing provided in the embodiment of the present application includes:

[0039] The annular mesh cover 1 comprises an annular plastic layer 11 and an annular metal layer 12, wherein the annular metal layer 12 is arranged on the outer surface of the annular plastic layer 11;

[0040] The front mesh cover 2 is buckled on the front opening of the annular mesh cover 1 . The front mesh cover 2 comprises a front mesh cover plastic layer 21 and a front mesh cover metal layer 22 . The front mesh cover metal layer 22 is arranged on the outer surface of the front mesh cover plastic layer 21 .

[0041] By way of example, in some embodiments of the present application, the shape of the annular mesh cover 1 is a rectangular cylindrical structure with open front and rear ends. The main structure of the annular mesh cover 1 is an annular plastic layer 11. The outer surface of the annular plastic layer 11 is wrapped with an annular metal layer 12, so that the outer surface of the annular mesh cover 1 has a metal appearance. The internal main body is made of plastic material, which reduces the weight of the annular mesh cover 1 and reduces the production cost of the annular mesh cover 1.

[0042] The overall shape of the front mesh cover 2 is a rectangular plate structure, and the main structure of the front mesh cover 2 is a front mesh cover plastic layer 21. A front mesh cover metal layer 22 is provided on the outer surface of the front mesh cover plastic layer 21, so that the front mesh cover 2 presents a metallic texture in appearance. The internal main body is made of plastic material, which reduces the weight of the front mesh cover 2 and reduces the production cost of the front mesh cover 2.

[0043] Furthermore, the projector housing is assembled by the annular mesh cover 1 and the front mesh cover 2, so the assembly structure is simple and the structural strength is high.

[0044] Furthermore, in some embodiments of the present application, the annular plastic layer 11 and the annular metal layer 12 are fixed by gluing.

[0045] Specifically, AB glue and 3M double-sided tape are set between the outer surface of the annular plastic layer 11 and the inner surface of the annular metal layer 12 for adhesion, which can not only ensure the connection strength between the annular plastic layer 11 and the annular metal layer 12, but also reduce the overall weight compared to using screw riveting or other fixing methods.

[0046] Further, combined with Figure 6 As shown, in some embodiments of the present application, a plurality of glue dispensing grooves 112 are provided on the outer surface of the annular plastic layer 11, and the glue dispensing grooves 112 are used to accommodate AB glue. AB glue is another name for a two-liquid mixed hardening glue, where one liquid is the glue and the other liquid is the hardener. The two liquids can only be hardened when mixed, and do not need to be hardened by temperature. The AB glue is filled into the glue dispensing grooves 112, and the AB glue is usually required to overflow the glue dispensing grooves 112. When the annular metal layer 12 and the annular plastic layer 11 are matched, the AB glue adheres the annular metal layer 12 and the annular plastic layer 11 together.

[0047] Exemplarily, in some embodiments of the present application, the depth of the glue dot groove 112 is 0.2 mm, and the number of the glue dot groove 112 is multiple, and the multiple glue dot grooves 112 are cross-arranged along the circumferential and length directions of the annular plastic layer 11. In the position where there is no glue dot groove 112, the annular plastic layer 11 and the annular metal layer 12 are fixed by 3M double-sided tape. The setting of the glue dot groove 112 strengthens the adhesion between the annular plastic layer 11 and the annular metal layer 12, and avoids the debonding phenomenon between the annular plastic layer 11 and the annular metal layer 12.

[0048] Ventilation holes are arranged on the left side wall, right side wall and / or bottom wall of the annular mesh cover 1. Specifically, honeycomb holes are arranged on the bottom wall and / or left and right side walls of the annular plastic layer 11 to reduce the overall weight of the annular mesh cover 1. Ventilation holes are arranged on the annular metal layer 12. The positions of the ventilation holes are arranged corresponding to the positions of the honeycomb holes, and the diameter of the ventilation holes is smaller than the diameter of the honeycomb holes. On the one hand, the interior of the projector can be ventilated and heat dissipated, and on the other hand, impurities such as external dust can be prevented from entering the interior of the projector housing and affecting the normal operation of the projector.

[0049] Furthermore, in some embodiments of the present application, a photosensitive hole 111 is provided on the annular plastic layer 11, and the photosensitive hole 111 penetrates the annular plastic layer 11 and the annular metal layer 12. The photosensitive light guide 3 is provided with an extension leg 31. The photosensitive light guide 3 is arranged in the photosensitive hole 111, and the extension leg 31 passes through the photosensitive hole 111 and enters the interior of the annular plastic layer 11. The extension leg 31 is fixed to the inner wall of the annular plastic layer 11 by hot riveting. The photosensitive light guide 3 is an element with certain light guiding properties, which can guide external light into the interior of the projector housing through the photosensitive light guide 3.

[0050] Specific, combined Figure 7 As shown, the end of the light-sensitive light guide 3 has at least two extended legs 31. After passing through the light guide hole, the at least two extended legs 31 are bent outward to form a flange. The flange is heated at a high temperature to cause the extended legs 31 and the annular plastic layer 11 to be denatured or even melted together, thereby achieving hot riveting fixation of the extended legs 31 and the annular plastic layer 11.

[0051] Hot riveting uses the property that metal or plastic materials are easily softened when heated, and the extended leg 31 is heated to a certain temperature before riveting. Since the plasticity of the extended leg 31 increases and the hardness decreases after heating, it is easy to form, so the external force required for hot riveting is much smaller than that for cold riveting; in addition, during the cooling process of the extended leg 31, the axial contraction of the extended leg 31 along the light-sensitive hole 111 will increase the positive pressure between the extended leg 31 and the annular plastic layer 11. When the extended leg 31 and the annular plastic layer 11 are subjected to force, greater friction resistance can be generated, thereby improving the riveting strength. Hot riveting is often used when the rivet material has poor plasticity, the rivet diameter is large, or the riveting force is insufficient.

[0052] The extended leg 31 is fixed to the annular plastic layer 11 by a hot riveting process, and the light-sensitive light guide 3 is not directly adhered to the annular plastic layer 11, which can ensure that the light-sensitive light guide 3 is not easy to fall off, and can also ensure that the light-sensitive light guide 3 has a certain elasticity when pressed and is not crushed.

[0053] For example, Figure 7 As shown, in some embodiments of the present application, the light-sensitive light guide 3 is a cylindrical structure, and two extension legs 31 are provided on the light-sensitive light guide 3, and the two extension legs 31 are connected to the outer circumference of the light-sensitive light guide 3 in a V shape. A heat rivet hole 32 is provided on the extension leg 31, and a heat rivet post is provided at a corresponding position of the annular plastic layer 11. During assembly, the heat rivet post passes through the heat rivet hole 32 accordingly, and the heat rivet fixation of the light-sensitive light guide 3 and the annular plastic layer 11 is achieved by high-temperature heating of the heat rivet post and the extension leg 31.

[0054] Further, combined with Figures 3 to 5As described, in some embodiments of the present application, an insert 4 is further provided on the projector housing, and the insert 4 is used to connect to the pan / tilt head. A groove 41 is provided on the insert 4, and a mounting hole is provided on the annular plastic layer 11. The insert 4 is passed through the mounting hole, and a protrusion 13 that is snap-fitted with the groove 41 is provided on the annular plastic layer 11.

[0055] Specifically, in some embodiments of the present application, the mounting hole passes through the annular plastic layer 11 and the annular metal layer 12, the insert 4 is inserted into the mounting hole, and a groove 41 is provided on the outer surface of one end of the insert 4 located inside the projector housing. The insert 4 is placed into the mold together during the injection molding process of the annular plastic layer 11. The pressure of the mold injection molding process is relatively high, which ensures that the insert 4 and the annular plastic layer 11 are in close contact and fit. Since the insert 4 has the groove 41, the annular plastic layer 11 will form a protrusion 13 entering the groove 41 at a position corresponding to the groove 41 during the injection molding process, thereby further ensuring the connection strength between the insert 4 and the annular plastic layer 11.

[0056] Exemplarily, in some embodiments of the present application, the shape of the insert 4 is cylindrical, the mounting hole is a circular hole, the mounting hole is formed on the left wall or the right wall of the annular mesh cover 1, the length of the insert 4 matches the thickness of the annular mesh cover 1, and a plurality of grooves 41 are arranged on the outer surface of the inner end of the insert 4 at circumferential intervals. During the injection molding process of the annular plastic part, the plastic material enters the groove 41 at a position corresponding to the groove 41 to form a protrusion 13.

[0057] like Figure 5 As shown, in some embodiments of the present application, three grooves 41 are provided on the insert 4, and three protrusions 13 are correspondingly formed on the annular plastic part.

[0058] An assembly hole 42 and a threaded hole 43 are provided on the insert 4 along the thickness direction of the side wall of the annular mesh cover 1. The assembly hole 42 is arranged along the center line of the insert 4. There are multiple threaded holes 43, and multiple threaded holes 43 are arranged around the assembly hole 42. The shape of the assembly hole 42 matches the shape of the connecting part on the pan-tilt head. When assembling with the pan-tilt head, the connecting part of the pan-tilt head is inserted into the assembly hole 42, and the screws are threadedly matched with the threaded holes 43 on the insert 4 to achieve a fixed connection between the pan-tilt head and the insert 4.

[0059] Further, combined with Figures 8 to 12 As shown, in some embodiments of the present application, the front mesh metal layer 22 is in the shape of a rectangular frame, and a plurality of air holes 222 are evenly distributed on the front mesh metal layer 22 .

[0060] Specifically, the front mesh cover plastic layer 21 is a rectangular plate, and structural holes such as a camera module extension hole, a ranging module extension hole or an optical machine module extension hole are set on the front mesh cover plastic layer 21. The camera module, the ranging module and the optical machine module are all arranged inside the projector housing. The above-mentioned camera module, the ranging module and the optical machine module are all existing technologies and will not be elaborated here. Among them, the optical machine module is used to project the image onto a screen or a plane, the camera module and the ranging module are directly fixed on the annular plastic layer 11 and locked, the ranging module is used for ranging, and the camera module is used for focusing and correction.

[0061] The lower part of the front mesh plastic layer 21 is provided with honeycomb holes to reduce the overall weight of the front mesh 2. The front mesh metal layer 22 is in the shape of a rectangular frame and completely covers the honeycomb holes at positions corresponding to the honeycomb holes.

[0062] Illustratively, in some embodiments of the present application, the front mesh cover metal layer 22 is surrounded by an upper side panel, a lower side panel, a left side panel and a right side panel. The width of the lower side panel of the front mesh cover metal layer 22 is greater than the width of the upper side panel and the left and right side panels of the front mesh cover metal layer 22. The lower side panel of the front mesh cover metal layer 22 can completely cover the area where the honeycomb holes are set on the front mesh cover plastic layer 21.

[0063] A plurality of ventilation holes 222 are evenly distributed on the front mesh cover metal layer 22, which not only has aesthetics, but also can achieve the effect of ventilation and heat dissipation.

[0064] The front grille metal layer 22 gradually tilts inward from the outer edge to the inner edge to form a concave effect on the front end surface of the projector housing, thereby improving the aesthetics of the overall structure.

[0065] Furthermore, in some embodiments of the present application, the front mesh cover metal layer 22 and the front mesh cover plastic layer 21 are fixed by gluing with AB glue and 3M double-sided tape. In order to prevent the AB glue and the 3M double-sided tape from falling off after a long period of use and affecting the fixing effect between the front mesh cover metal layer 22 and the front mesh cover plastic layer 21, in addition to gluing fixation, the front mesh cover metal layer 22 and the front mesh cover plastic layer 21 are also fixed by clipping.

[0066] Specifically, in some embodiments of the present application, a rearward protrusion 13 on the inner side surface of the front mesh cover metal layer 22 forms a clamping plate 221, and a first clamping hole 213 is set at a corresponding position of the front mesh cover plastic layer 21. The clamping plate 221 passes through the first clamping hole 213 to clamp and fix the front mesh cover metal layer 22 and the front mesh cover plastic layer 21.

[0067] Illustratively, in some embodiments of the present application, a plurality of snap-in plates 221 are evenly arranged along the circumferential direction on the inner and outer edges of the front mesh cover metal layer 22, that is, a plurality of snap-in plates 221 are arranged on the inner and outer edges of the upper side plate, the inner and outer edges of the lower side plate, the inner and outer edges of the left side plate, and the left and right edges of the right side plate, and a first snap-in hole 213 is arranged at a corresponding position of the front mesh cover plastic layer 21, and the snap-in plates 221 pass through the first snap-in holes 213 one by one and are bent to realize the snap-in fixation of the front mesh cover metal layer 22 and the front mesh cover plastic layer 21.

[0068] Specifically, the clamping plate 221 includes a first connecting section 2211, a second connecting section 2212 and a third connecting section 2213 in sequence along the direction away from the front mesh metal layer 22, wherein the first connecting section 2211 is inserted into the first clamping hole 213 and cooperates with the first clamping hole 213, the second connecting section 2212 and the third connecting section 2213 pass through the first clamping hole 213 from front to back and are located on the back side of the front mesh plastic layer 21, the strength of the second connecting section 2212 is smaller than the width of the first connecting section 2211 and the third connecting section 2213, so as to facilitate bending the clamping plate 221 at the second connecting section 2212, after bending, the third connecting plate is fitted with the back side of the front mesh plastic layer 21, and mutual interference is formed between the third connecting plate and the front mesh plastic layer 21, so as to prevent the clamping plate 221 from slipping out of the first clamping hole 213 forward.

[0069] Exemplarily, the first connecting section 2211, the second connecting section 2212 and the third connecting section 2213 are made of the same material and are all plate-like structures. The thickness or width of the second connecting section 2212 is smaller than the thickness or width of the first connecting section 2211 and the third connecting section 2213, so that the clamping plate forms a weak area at the second connecting section 2212, so as to facilitate bending the clamping plate at the second connecting section 2212.

[0070] Furthermore, a snap-in groove is formed on the back side surface of the front mesh cover plastic layer 21, and the snap-in groove is located on one side of the first snap-in hole 213 and is connected to the interior of the first snap-in hole 213. After the snap-in plate 221 is bent on the second connecting plate, the third connecting plate is located in the snap-in groove, and the snap-in groove forms a limit for the third connecting plate, thereby avoiding the shaking between the snap-in plate 221, the first snap-in hole 213 and the snap-in groove, and ensuring the stability of the connection structure between the front mesh cover metal layer 22 and the front mesh cover plastic layer 21.

[0071] The front mesh cover plastic layer 21 is provided with a clamping plate 221 at a position corresponding to the clamping plate 221 at the inner edge of the upper side plate, the lower side plate, the left side plate and the right side plate of the front mesh cover metal layer 22; the clamping plates 221 located at the outer edge of the upper side plate, the lower side plate, the left side plate and the right side plate of the front mesh cover metal layer 22 are arranged around the front mesh cover plastic layer 21, and a limiting groove is provided at a corresponding position on the side of the front mesh cover plastic layer 21, the clamping plate 221 is correspondingly located in the limiting groove, a clamping groove is formed on the back side of the front mesh cover plastic layer 21, and the second connecting section 2212 of the clamping plate 221 is bent and located in the clamping groove.

[0072] Furthermore, in some embodiments of the present application, an anti-vibration layer 23 is provided between the front mesh cover metal layer 22 and the front mesh cover plastic layer 21. The anti-vibration layer 23 can be anti-vibration foam or black gauze to avoid hard contact between the front mesh cover metal layer 22 and the front mesh cover plastic layer 21, thereby reducing the impact of resonance on the entire projector during transportation and use.

[0073] Exemplarily, in some embodiments of the present application, the vibration-proof layer 23 is a black gauze, which is shaped like an inverted "U" shape, and the black gauze is arranged corresponding to the upper side plate, left side plate and right side plate of the front mesh cover metal layer 22.

[0074] Furthermore, in some embodiments of the present application, the front mesh plastic layer 21 and the annular plastic layer 11 are fixed by a plurality of fasteners 5 , and the plurality of fasteners 5 are evenly distributed along the circumference of the annular plastic layer 11 .

[0075] Specifically, 16 fixing columns 211 are axially spaced apart on the back side near the outer edge of the front mesh plastic layer 21, and threaded holes are provided in the fixing columns 211 along the axial direction. A connecting ear plate is provided at a position corresponding to the fixing columns 211 on the inner wall of the front end opening of the annular plastic layer 11, and a through hole is provided on the connecting ear plate. The fastener 5 is a screw, which passes through the through hole on the connecting ear plate and is threadedly matched with the threaded hole on the fixing column to achieve mutual fixation of the front mesh plastic layer 21 and the annular plastic layer 11.

[0076] The screws are inserted from the inside to the outside, and the screws cannot be seen on the external structure of the projector shell, thereby improving the aesthetics of the projector shell.

[0077] Furthermore, a hook 212 is provided on the back side of the front mesh cover plastic layer 21, and a second snap-in hole 113 is provided at a corresponding position of the annular plastic layer 11. The hook 212 cooperates with the second snap-in hole 113. During assembly, the hook 212 is correspondingly inserted into the second snap-in hole 113, and the front mesh cover plastic layer 21 is pressed backward so that the hook 212 passes through the second snap-in hole 113 and snaps into the annular plastic layer 11, which not only can achieve the pre-positioning of the front mesh cover plastic layer 21 and the annular plastic layer 11, but also can increase the connection strength between the front mesh cover plastic layer 21 and the annular plastic layer 11.

[0078] By fixing the fastener 5 and snapping the hook 212 with the second snapping hole 113, it is ensured that there will be no large gap between the front mesh cover 2 and the annular mesh cover 1, thereby improving the installation accuracy, controlling the gap between the front mesh cover 2 and the annular metal layer 12, and improving the appearance.

[0079] Furthermore, in some embodiments of the present application, the annular metal layer 12 and the front mesh metal layer 22 are both made of thin aluminum sheets, which can ensure both strength and metallic texture.

[0080] Furthermore, a trademark plate 24 is provided on the front mesh cover 2, and the trademark plate 24 is fixedly connected to the front mesh cover 2 via mounting feet provided on the back side.
