[0048] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0049] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0050] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0053] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0054] In related technologies, a base is incorporated into the projector to support and place it. Typically, the base is directly connected to the projector's outer casing. However, due to the projector's inherent weight and height, the overall stability of this assembly method needs improvement. Furthermore, for vertical projectors, the increased height makes maintaining stability even more challenging.

[0055] Based on this, the embodiments of this application improve the stability of the entire device by connecting the base to a component with a certain weight inside the projector. The projector provided in the embodiments of this application will now be described in conjunction with the accompanying drawings.

[0056] Figure 1 A schematic diagram of the structure of a projector 10 shown in one embodiment of this application is illustrated. Figure 2 It shows Figure 1 The diagram shows a partial explosion structure of the projector 10 in one mode. Figure 3 It shows Figure 1 The diagram shows a partial explosion of the projector 10 in another manner; for ease of explanation, only the content related to the embodiments of this application is shown.

[0057] In some embodiments, please refer to Figures 1 to 3 This application provides a projector 10, which includes a housing 100, an optical engine assembly 200, a base 300, and a connector 400.

[0058] The housing 100 has an internal accommodating space for housing the optical engine assembly 200 and related components. These related components are those included in the projector 10 and require housing within the housing 100. Figures 1 to 3 For example, the outer casing 100 includes a rear casing 110 and a front casing 120, which together form the aforementioned receiving space. The rear casing 110 and the front casing 120 can be detachably connected (e.g., snap-fit ​​connection, screw connection, etc.). A decorative piece 130 can be provided on the front side of the front casing 120. Corresponding functional holes (e.g., heat dissipation holes, lens holes, etc.) are provided on the decorative piece 130. It can be understood that the front casing 120 is located in front of the rear casing 110, and "front" and "rear" are relative to the light emission direction of the projector 10. The upstream of the light emission direction is the rear, and the downstream of the light emission direction is the front.

[0059] The optical-mechanical assembly 200 includes functional components (such as lens assembly, circuit board, etc.) and structural components (such as housing, connecting components, etc.) for imaging. The optical-mechanical assembly 200 is fixed inside the housing 100. That is, the optical-mechanical assembly 200 and the housing 100 are relatively fixed to each other.

[0060] The base 300 supports the entire unit. At least a portion of the base 300 is located outside the outer casing 100. That is, the base 300 can be completely outside the outer casing 100, or partially outside and partially inside the outer casing 100. It can be understood that "inside" and "outside" of the outer casing 100 are relative to the accommodating space formed by the outer casing 100. The area inside the accommodating space is considered inside the outer casing 100, and the area outside the accommodating space is considered outside the outer casing 100. Further elaboration on this will not be repeated hereafter. Figures 1 to 3 For example, this illustrates the case where the base 300 is located outside the outer casing 100.

[0061] The connector 400 serves to provide a connection. The connector 400 connects to the optomechanical assembly 200 and the base 300, thereby fixing the optomechanical assembly 200 relative to the base 300. Since at least a portion of the base 300 is located outside the housing 100, and at least a portion of the optomechanical assembly 200 is located inside the housing 100, the connector 400 may or may not pass through the housing 100, depending on the specific application. As long as the connector 400 can connect to the optomechanical assembly 200 and the base 300, this embodiment does not impose specific limitations in this regard.

[0062] Therefore, since the optical engine assembly 200 is a component with a certain weight in the projector 10, or even the heaviest component, and the optical engine assembly 200 is connected to the base 300, the base 300 supports the component with a certain weight in the whole machine, thereby improving the stability of the whole machine.

[0063] In some embodiments, please continue to refer to Figures 1 to 3 The projector 10 also includes a mounting bracket 500. The mounting bracket 500 is at least partially located within the housing 100 and connected to the optical engine assembly 200. That is, the mounting bracket 500 can be completely located within the housing 100, or partially located within and partially outside the housing 100. Figures 1 to 3 For example, the mounting bracket 500 is shown inside the housing 100. The connector 400 is connected to the base 300 and the mounting bracket 500 to fix the optomechanical assembly 200 relative to the base 300.

[0064] Since the optomechanical assembly 200 is connected to the base 300 by means of the mounting bracket 500 and the connector 400, the mounting bracket 500 facilitates the assembly of the optomechanical assembly 200 and improves its assemblability.

[0065] Figure 4 It shows Figure 1 The diagram shows the structure of the rear shell 110 of the projector 10 from one viewpoint. Figure 5 It shows Figure 4 A magnified schematic diagram of the partial structure at point A in the middle; Figure 6 It shows Figure 1 The diagram shows the structure of the rear shell 110 of the projector 10 from another perspective; for ease of explanation, only the content related to the embodiments of this application is shown.

[0066] In some embodiments, please continue to refer to Figures 1 to 3 and in conjunction with reference Figures 4 to 6 The mounting bracket 500 is entirely located within the housing 100. The bottom of the housing 100 has a through hole k; the connector 400 is connected to the base 300 and passes through the through hole k to connect with the mounting bracket 500. Figures 4 to 6For example, it is illustrated that a through hole k is provided at the bottom of the rear housing 110, at least a portion of the optical engine assembly 200 is located inside the rear housing 110, and the portion of the optical engine assembly 200 located in the rear housing 110 is connected to the mounting bracket 500.

[0067] Since the optical engine assembly 200 and the mounting bracket 500 are all housed within the housing 100, when the base 300 is connected to the mounting bracket 500, the housing 100 is sandwiched between the base 300 and the mounting bracket 500. In this way, the strength of the housing 100 can be used to further improve the reliability of the connection, thereby improving the stability of the whole machine.

[0068] Figure 7 It shows Figure 1 The diagram shows an exploded view of the optomechanical assembly 200 and the mounting bracket 500 in the projector 10; for ease of explanation, only the content related to the embodiments of this application is shown.

[0069] In some embodiments, please continue to refer to Figure 4 and Figure 5 and in conjunction with reference Figure 7 The bottom of the outer casing 100 has a mating surface m1 facing the mounting bracket 500, and a through hole k penetrates the mating surface m1. The mounting bracket 500 has a mounting surface m2 facing the mating surface m1, and the mounting surface m2 can abut against the mating surface m1. Figures 4 to 6 For example, the mating surface m1 is located at the bottom of the rear shell 110.

[0070] Thus, the fit between the mounting surface m2 and the mating surface m1 makes the fit between the mounting bracket 500 and the housing 100 more stable and reliable.

[0071] In some embodiments, please continue to refer to Figure 4 and Figure 5 and in conjunction with reference Figure 7 Multiple support structures c are protruding on the mating surface m1. The mounting surface m2 abuts against the mating surface m1 with the help of the support structures c.

[0072] This allows a gap to be formed between the mounting bracket 500 and the mating surface m1, which facilitates the installation of the mounting bracket 500 while reducing the contact area between the mounting bracket 500 and the mating surface m1. This helps to mitigate the transmission of vibrations from other components (such as speakers) located inside the housing 100 to the housing 100, thereby further improving the overall stability of the device.

[0073] In some embodiments, please continue to refer to Figure 7The supporting structure c is constructed as a supporting rib. In this way, constructing the supporting structure c as a supporting rib not only increases the strength, but also further reduces the contact area between the mounting bracket 500 and the mating surface m1.

[0074] In other embodiments, please continue to refer to Figure 7 The extension direction of the support structure c is the same as the installation direction of the mounting bracket 500, so as to facilitate the installation of the mounting bracket 500.

[0075] In some embodiments, please continue to refer to Figure 4 and Figure 5 and in conjunction with reference Figure 7 The bottom of the housing 100 is also provided with a guide structure x located inside the housing 100. The guide structure x can be connected to the mating surface m1. The guide structure x is used to guide the mounting bracket 500 when it is installed on the base 300. This facilitates the installation of the mounting bracket 500.

[0076] In some embodiments, please continue to refer to Figure 4 and Figure 5 and in conjunction with reference Figure 7 The guide structure x is constructed as a guide rib. In this way, constructing the guide structure x as a guide rib not only guides the installation of the mounting bracket 500, but also makes reasonable use of the internal space of the outer shell 100.

[0077] In some embodiments, please continue to refer to Figure 4 and Figure 5 and in conjunction with reference Figure 7 The extension direction of the guide structure x is the same as the installation direction of the mounting bracket 500, so as to guide the mounting bracket 500.

[0078] In some embodiments, please continue to refer to Figure 4 and Figure 5 Both the mounting surface m2 and the mating surface m1 are constructed as planes. This facilitates the assembly and installation of the bracket 500 using a planar structure. Meanwhile, other parts of the housing 100 can be designed in shapes such as circles to improve the aesthetics of the housing 100. In other words, since the mating surface m1 is located at the bottom of the housing 100, its impact on the design of the housing 100 is reduced.

[0079] In some embodiments, please continue to refer to Figures 4 to 6 The bottom of the outer casing 100 has a recessed portion p, the recessed direction of which is from the bottom of the outer casing 100 towards the inside of the outer casing 100. The mating surface m1 is the side surface of the bottom wall of the recessed portion p facing the inside of the outer casing 100. Figures 4 to 6For example, the recessed portion p is illustrated when it is located at the bottom of the rear shell 110. The bottom wall of the recessed portion p can be set as a flat plate to form a mating surface m1. Of course, the surface of the bottom wall of the recessed portion p facing the outer shell 100 can also be flat to form the required mating surface m1. It can be set according to the specific use case, and this application embodiment does not impose specific limitations on it. As one implementation method, please continue to refer to Figure 5 In the guide structure x shown in some of the above embodiments, the guide structure x can be constructed as a guide rib. The guide structure x is connected to the side wall of the recess p, and the side of the guide structure x facing the inside of the outer shell 100 is flush with the mating surface m1.

[0080] Thus, by setting the recessed part p, it is not only convenient to install the base 300 on the outside of the housing 100 and improve the appearance, but also convenient to form the required mating surface m1 inside the housing 100 to install the mounting bracket 500.

[0081] Figure 8 It shows Figure 1 The diagram shows the structure of the base 300 in the projector 10; for ease of explanation, only the content related to the embodiments of this application is shown.

[0082] In some embodiments, please refer to Figure 6 and Figure 8 The base 300 is provided with a first positioning structure d1, and the bottom of the outer casing 100 is provided with a second positioning structure d2. The first positioning structure d1 and the second positioning structure d2 are adapted to position the base 300 against the mating surface m1. For example, with Figure 6 For example, a recessed portion p is provided at the bottom of the rear shell 110, and a second positioning structure d2 is provided on the surface of the bottom wall of the recessed portion p facing outward from the outer shell 100. The second positioning structure d2 is a positioning post. Correspondingly, such as Figure 8 As shown, the first positioning structure d1 on the base 300 is a positioning hole.

[0083] Thus, by setting a first positioning structure d1 and a second positioning structure d2 that is compatible with the first positioning structure d1, it is easy to position the base 300 relative to the mating surface m1, thereby facilitating the installation of the base 300.

[0084] In some embodiments, the bottom of the housing 100 has an opening. The opening is configured to expose the mounting bracket 500 so that the connector 400 can be connected to the base 300 and the mounting bracket 500. That is, the exposed mounting bracket 500 can be directly connected to the base 300. This also facilitates the connection between the mounting bracket 500 and the base 300.

[0085] Figure 9 It shows Figure 1The diagram shows the structure of the mounting bracket 500 in the projector 10; for ease of explanation, only the content related to the embodiments of this application is shown.

[0086] In some embodiments, please refer to Figure 8 and Figure 9 The mounting bracket 500 has a first mounting structure a1, and the base 300 has a second mounting structure a2. The first mounting structure a1 and the second mounting structure a2 are adapted to each other, and the connector 400 is connected to the mounting bracket 500 and the base 300 via the first mounting structure a1 and the second mounting structure a2. In some embodiments, the first mounting structure a1 is constructed as a stud, and the second mounting structure a2 is constructed as a mounting hole formed in the base 300. The connector 400 can be threadedly connected to the first mounting structure a1. Of course, the first mounting structure a1 can also be constructed with a structure having a threaded hole, so as to... Figure 9 Taking the first mounting structure a1 as an example, the first mounting structure a1 can be configured with an edge... Figure 9 The threaded hole in the first mounting structure a1 extends vertically, and correspondingly, the connector 400 can pass through the threaded hole in the first mounting structure a1 and be threadedly connected to the first mounting structure a1. In other embodiments, please refer to... Figures 4 to 6 The bottom of the outer casing 100 is provided with a through hole k, and the connector 400 can pass through the outer casing 100 via the through hole k to connect the mounting bracket 500 and the base 300.

[0087] Thus, with the help of the first mounting structure a1 and the second mounting structure a2, it is easy for the connector 400 to connect the mounting bracket 500 and the base 300.

[0088] In some embodiments, please refer to Figure 2 and Figure 9 The first mounting structure a1 is located on the side of the mounting bracket 500 facing the optomechanical assembly 200. This allows for more efficient use of the space within the housing 100. Furthermore, the presence of a mating surface m1 within the housing 100 facilitates the mating of the mounting surface m2 of the mounting bracket 500 with the mating surface m1.

[0089] In some embodiments, please continue to refer to Figure 8 The base 300 includes a seat 310 and a mounting member 320. The seat 310 can be constructed as a plate, and the mounting member 320 is rotatably connected to the seat 310. The first positioning structure d1 and the first mounting structure a1 shown in some of the foregoing embodiments are provided on the mounting member 320. In this way, the angle of the projector 10 can be adjusted.

[0090] In some embodiments, please continue to refer to Figure 7The optomechanical assembly 200 includes an optomechanical body 210 and a circuit board bracket 220 located at the bottom of the optomechanical body 210. The circuit board bracket 220 is connected to the mounting bracket 500. The circuit board bracket 220 is used to mount the circuit board 230. Figure 7 For example, circuit board 230 can be located between mounting bracket 500 and circuit board bracket 220. In this way, by using circuit board bracket 220 within the optomechanical assembly 200, not only circuit board 230 can be mounted, but also mounting bracket 500 can be mounted, making the overall structure simpler.

[0091] In some embodiments, please continue to refer to Figure 7 The mounting bracket 500 has a third mounting structure b1, the circuit board 230 has a fourth mounting structure b2, and the circuit board bracket 200 has a fifth mounting structure (not shown in the figure). The third mounting structure b1, the fourth mounting structure b2, and the fifth mounting structure are compatible with each other. In some embodiments, the third mounting structure b1, the fourth mounting structure b2, and the fifth mounting structure are constructed as holes, allowing bolt assemblies to pass through and securely connect the mounting bracket 500, the circuit board 230, and the circuit board bracket 220. Alternatively, the mounting bracket 500 may have a third mounting structure b1, the circuit board bracket 200 may have a fifth mounting structure, and bolt assemblies may pass through and securely connect the mounting bracket 500 and the circuit board bracket 220, depending on the specific application. Thus, the connection between the mounting bracket 500, the circuit board bracket 220, and the circuit board 230 can be achieved by setting the relevant mounting structures.

[0092] In some embodiments, please continue to refer to Figure 9 The mounting bracket 500 has folded edges z on opposite sides, with both folded edges z facing the circuit board bracket 220. Correspondingly, a flange f can be provided on the side of the folded edge z away from the mounting bracket 500, and the third mounting structure b1 shown in some of the aforementioned embodiments can be provided on the flange f. It is understood that the position and number of flanges f can be set according to the usage requirements of the third mounting structure b1. Figure 7 and Figure 9 For example, this illustration shows a scenario where four third mounting structures b1 and four flanges f are provided, meaning that each end of the flange z on each side is provided with a third mounting structure b1. After the mounting bracket 500 and the circuit board bracket 220 are installed together, a heat dissipation channel can be formed between the mounting bracket 500 and the circuit board bracket 220, and the circuit board 230 can be placed within this heat dissipation channel. A corresponding heat dissipation component (such as a cooling fan) can be provided inside the housing 100. The heat dissipation component allows airflow to pass through the heat dissipation channel to cool the circuit board 230, thereby improving the heat dissipation efficiency of the circuit board 230.

[0093] It is understandable that the mounting bracket 500, the folded edge z, and the flange f can be either a one-piece structure or a separate structure. A one-piece structure refers to a structure that can be manufactured using a single molding process. A separate structure refers to a structure where independent components are connected to each other. Figure 9 For example, this illustration shows a scenario where the mounting bracket 500, the folded edge z, and the flange f are an integrated structure. The configuration can be adjusted according to the usage, and this embodiment does not impose specific limitations on this.

[0094] In some embodiments, please continue to refer to Figure 7 The circuit board support 220 can also be provided with a positioning element w, and correspondingly, the mounting bracket 500 can be provided with a mating hole adapted to the positioning element w. Thus, before the mounting bracket 500 is installed on the circuit board support 220, the engagement between the positioning element w and the mating hole allows the mounting bracket 500 to be positioned on the circuit board support 220, facilitating the installation of the mounting bracket 500. It is understood that when the circuit board 230 is located between the mounting bracket 500 and the circuit board support 220, an opening s adapted to the positioning element 221 can also be provided on the circuit board 230. The positioning element 221 is located at the opening s and on the side of the circuit board 230 facing the mounting bracket 500, so that the positioning element 221 can engage with the mating hole. The positioning element w can be a columnar structure. Thus, the position of the positioning element w can be set according to the specific application, as long as positioning can be achieved; this embodiment does not impose specific limitations in this regard.

[0095] In summary, this embodiment of the application connects the optical engine assembly 200 to the base 300, allowing the base 300 to bear the weight of the components in the entire device, thereby improving the overall stability of the device. Specifically, by providing a through hole k at the bottom of the outer shell 100, the outer shell 100 can be clamped between the base 300 and the mounting bracket 500, further improving the overall stability of the device by utilizing the strength of the outer shell 100. By providing a mating surface m1 and a corresponding guide structure x at the bottom of the outer shell 100, it is convenient to install the mounting bracket 500 and the base 300. By providing a support structure c on the mating surface m1, the transmission of vibrations generated inside the outer shell 100 can be mitigated. By providing a recess p at the bottom of the outer shell 100 to form the mating surface m1, not only can the internal space of the outer shell 100 be rationally utilized, but it is also convenient to install and mate with the base 300 and the mounting bracket 500. Thus, through the mutual cooperation of the various components in the projector 10, the overall stability of the device is further improved.
