[0002] A projector is an electronic device that projects images or videos onto a screen or wall. It can connect to devices such as computers, mobile phones, TV boxes, and game consoles via various interfaces to play corresponding image or video signals. Users need to adjust the projector's tilt angle according to their needs. In related technologies, tilt adjustment is achieved by using an adjustable base at the bottom of the projector.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] Figure 1 A schematic diagram of the structure of the base 100 shown in one embodiment of this application is illustrated. Figure 2 It shows Figure 1 The diagram shows a partial exploded view of the base 100; for ease of explanation, only the content relevant to the embodiments of this application is shown.

[0064] In some embodiments, please refer to Figure 1 and Figure 2 This application provides a base 100, including a seat 110, a mounting member 120, and two rotating assemblies 130. The seat 110 supports the remaining components on the base 100 and the projector body. The seat 110 may be plate-shaped, meaning that the extending direction of the seat 110 (i.e., the direction perpendicular to the thickness direction of the seat 110) is generally along a plane. The two surfaces of the seat 110, which are arranged opposite each other along the thickness direction of the seat 110, are generally planar. They may be flat or not perfectly flat (i.e., they may have a certain degree of roughness), as long as the extending direction of the seat 110 is along a plane. The relevant components supported by the seat 110 may be located on one of the aforementioned two surfaces. For example, Figure 1The upper surface of the base 110 is shown in the diagram. The mounting member 120 is used to connect the projector body. For example, this component can be the housing 200 of the projector 10 shown later. Two rotating assemblies 130 are disposed opposite each other on both sides of the mounting member 120 along a first direction F1. Each rotating assembly 130 includes a support assembly 131 and a rotating member 132. The support assembly 131 is mounted on the base 110, and one end of the rotating member 132 is rotatably connected to the support assembly 131, while the other end is mounted on the mounting member 120. The rotating member 132 can rotate relative to the support assembly 131 under the influence of the mounting member 120. The rotation axis L of the rotating member 132 is parallel to the first direction F1.

[0065] The housing 200 of the projector 10 is connected to the mounting bracket 120 (see the diagram below). Figure 12 and Figure 13 For example, when a user applies force to the outer casing 200 to adjust the pitch angle of the projector 10, the rotating component 132 can be rotated by the mounting component 120. The support component 131, mounted on the base 110, provides support. Thus, the pitch adjustment of the projector 10 is achieved. In the base 100 provided in this embodiment, by arranging two rotating components 130 opposite each other along the first direction F1 on both sides of the mounting component 120, the rotating components 130 are divided into two parts, facilitating assembly of the rotating components 130 from both sides of the mounting component 120, and then mounting the rotating components 130 to the base 110. Therefore, the overall structure of the base 100 is simple, reducing structural complexity and improving assemblability.

[0066] Figure 3 It shows Figure 1 The schematic diagram of the rotating component 130 in the base 100 is shown in the figure. Figure 4 It shows Figure 3 A schematic diagram of the rotating assembly 130 from another perspective; Figure 5 It shows Figure 3 The exploded structural diagram of the rotating assembly 130 is shown; for ease of explanation, only the content related to the embodiments of this application is shown. Figure 4 Another perspective in Figure 3 The rear view in the middle.

[0067] In some embodiments, please continue to refer to Figure 2 and in conjunction with reference Figures 3 to 5The rotating member 132 includes a rotating portion 132a and a connecting portion 132b connected to the rotating portion 132a. The rotating portion 132a is rotatably connected to the support assembly 131, and the connecting portion 132b is mounted on the mounting member 120. The connecting portion 132b has a first end b1 connected to the rotating portion 132a and a second end b2 mounted on the mounting member 120. The direction from the first end b1 to the second end b2 is parallel to a first direction F1 and the rotation axis L, respectively. That is, one extending direction of the connecting portion 132b is parallel to the first direction F1 and the rotation axis L, respectively.

[0068] It should be noted that the rotating part 132a and the connecting part 132b can be either an integral structure or a separate structure. An integral structure means that the rotating part 132 is manufactured using an integral molding process, while a separate structure means that the rotating part 132a and the connecting part 132b in the rotating part 132 are fixedly connected. The configuration can be tailored to specific applications, and this embodiment does not impose any specific limitations on this.

[0069] Thus, since the connecting part 132b has a certain extension length in the first direction F1, the second end b2 of the connecting part 132b and the mounting part 120 can form a large contact area, making the process of the mounting part 120 driving the rotating part 132 to rotate more stable and reliable.

[0070] In some embodiments, please continue to refer to Figure 1 and Figure 2 and in conjunction with reference Figures 3 to 5 The rotating part 132a has a rotating end a1 and a connecting end a2. The rotating end a1 is rotatably connected to the support assembly 131, and the connecting end a2 is connected to the connecting part 132b. The direction in which the rotating end a1 points to the connecting end a2 is perpendicular to the direction in which the first end b1 points to the second end b2. That is, one extension direction of the rotating part 132a is perpendicular to one extension direction of the connecting part 132b. In this way, the rotating member 132 is formed into an L-shaped component.

[0071] Therefore, since the rotating component 132 is connected between the support assembly and the mounting component 120, and the rotating component 132 is approximately "L" shaped, compared to the mounting component 120 being directly rotatably connected to the support assembly, it not only facilitates the assembly of the rotating component 132, but also makes the connection of the rotating component 132 more reliable.

[0072] In some embodiments, please continue to refer to Figures 3 to 5The support assembly 131 includes a first support member 131a, a second support member 131b, and a fastening assembly 131c. The first support member 131a is mounted on the base 110. The second support member 131b includes a fixed part g1 and a mounting part g2 connected together. The fixed part g1 is fixed to the first support member 131a, and the mounting part g2 passes through the rotating member 132. The fastening assembly 131c is sleeved on the mounting part g2 and is used to provide a fastening force acting on the rotating member 132 along a first direction F1, so that the rotating member 132 has a first state and a second state. In the first state, the rotating member 132 can be fixed relative to the second support member 131b. In the second state, the rotating member 132 can rotate relative to the second support member 131b under the drive of the mounting member 120.

[0073] Thus, by setting the fastening component 131c, the fastening force exerted by the fastening component 131c on the rotating member 132 ensures that the rotating member 132 is fixed relative to the second support member 131b when not subjected to the action of the mounting member 120. When the rotating member 132 is subjected to the action of the mounting member 120, it can overcome the limitation of the fastening force and rotate under a certain force. It is understood that the fastening force can be set according to the usage requirements, and this embodiment does not impose specific limitations on it.

[0074] In some embodiments, please continue to refer to Figure 5 The fixing part g1 of the second support member 131b can be snapped onto the first support member 131a. Specifically, the first support member 131a is provided with a corresponding snap-fit ​​hole k1, the contour of which matches the contour of the fixing part g1. For example, the snap-fit ​​hole k1 can be constructed as a non-circular hole to improve the reliability of the second support member 131b being fixed to the first support member 131a.

[0075] In some embodiments, please continue to refer to Figure 5 The second support member 131b also includes a protrusion g3 connecting the fixing part g1 and the mounting part g2. When the fixing part g1 is installed on the first support member 131a, the protrusion g3 abuts against the first support member 131a. Thus, the protrusion g3 can be used to confirm whether the second support member 131b is installed in place.

[0076] In some embodiments, please continue to refer to Figure 3 and Figure 5 The fastening assembly 131c includes a fastener c1 and at least one adjusting member c2. The fastener c1 and the adjusting member c2 are sleeved outside the mounting portion g2, with the adjusting member c2 located between the rotating member 132 and the fastener c1. Figure 3 and Figure 5For example, fastener c1 can be a nut, and mounting part g2 has a corresponding threaded section that mates with fastener c1. Fastener c1 is fastened to mounting part g2 by means of the threaded section. Adjusting member c2 is a component used to adjust the fastening force of fastener c1 on rotating part 132. For example, adjusting member c2 can be a washer. Figure 5 For example, this illustration shows a scenario where there are seven adjusting members c2. The number and position of the adjusting members c2 can be set according to the usage, and this embodiment does not impose specific limitations on this.

[0077] Thus, by setting fastener c1 and adjusting component c2 in a coordinated manner, the fastening force can be easily adjusted as needed.

[0078] In some embodiments, please continue to refer to Figure 3 and Figure 5 The support assembly 131 further includes a limiting member 131d, which is sleeved outside the mounting portion g2 and located on one side of the rotating member 132 along the first direction F1. Two rotation limiting portions 132c are provided on the side of the rotating member 132 facing the limiting member 131d, and the two rotation limiting portions 132c are distributed on both sides of the limiting member 131d along the first direction F1. The rotating member 132 has a first limit position and a second limit position during rotation. In the first limit position, one of the rotation limiting portions 132c abuts against the limiting member 131d. In the second limit position, the other rotation limiting portion 132c abuts against the limiting member 131d.

[0079] Thus, by fitting the limiting member 131d onto the mounting part g2, the rotating member 132 has a rotation range between the first limit position and the second limit position. During the pitch adjustment process of the projector 10, the projection of the projector 10 can be kept within an effective working range by limiting the rotation range of the rotating member 132.

[0080] In some embodiments, please continue to refer to Figure 5 The limiting member 131d has an abutment portion j, which has a first side and a second side along a first direction F1. The rotating member 132 is in a first extreme position, where one of the rotation limiting portions 132c abuts against the first side of the abutment portion j. The rotating member 132 is in a second extreme position, where the other rotation limiting portion 132c abuts against the second side of the abutment portion j. That is, along the rotation direction of the rotating member 132, one rotation limiting portion 132c is located downstream of the abutment portion j, and the other rotation limiting portion 132c is located upstream of the abutment portion j. Of course, in other embodiments, abutment portions j corresponding one-to-one with the rotation limiting portions 132c can also be provided, as long as the rotating member 132 has a restricted rotation range. This application embodiment does not impose specific limitations on this.

[0081] In some embodiments, please continue to refer to Figure 5 The support assembly 131 also includes a mating member c3. The mating member c3 is rotatably mounted on the mounting portion g2 and is located on the side of the limiting member 131d opposite to the rotating portion 132a of the rotating member 132. The mating member c3 has a mating portion c31 extending toward the rotating portion 132a, and the rotating portion 132a has a snap-fit ​​portion h, and the mating portion c31 snaps into the snap-fit ​​portion h.

[0082] Thus, by setting the mating part c3, the limiting part 131d can be limited between the mating part c3 and the rotating part 132a, thereby improving the reliability of the mating between the rotating part 132a and the limiting part 131d.

[0083] In some embodiments, please continue to refer to Figures 1 to 4 The mounting component 120 is provided with a first anti-foolproof structure f1, and the rotating assembly 130 is provided with a second anti-foolproof structure f2 corresponding to the first anti-foolproof structure f1. In this way, two rotating assemblies 130 can be installed correspondingly with the help of the corresponding anti-foolproof structures.

[0084] For specific embodiments, please refer to... Figures 1 to 4 The first foolproof structure f1 and the second foolproof structure f2 can be foolproof markings. Figures 1 to 4 For example, the first foolproof structure f1 includes foolproof markings "L" and "R". The second foolproof structure f2 on the connecting portion 132b of the rotating member 132 of one rotating assembly 130 includes the foolproof marking "L", and the second foolproof structure f2 on the connecting portion 132b of the rotating member 132 of another rotating assembly 130 includes the foolproof marking "R". Thus, since the projector 10 has an initial pitch angle after assembly, the corresponding foolproof markings facilitate the installation of the corresponding rotating assembly 130.

[0085] Figure 6 It shows Figure 1 A schematic diagram of the structure of the mounting component 120 in the base 100 is shown; Figure 7 It shows Figure 6 A schematic diagram of the structure of the mounting component 120 shown from another perspective; Figure 8 It shows Figure 7 A partially enlarged structural diagram at point A; for ease of explanation, only the content related to the embodiments of this application is shown. Figure 7 Another perspective in Figure 6 The upward-looking perspective in the main view direction.

[0086] In some embodiments, please continue to refer to Figure 1 and Figure 2 and in conjunction with reference Figures 6 to 8The mounting part 120 is provided with a first mounting limiting part s1. The first mounting limiting part s1 is configured to have a limiting space extending along the first direction F1, and the connecting part 132b can be inserted along the first direction F1 and limited within the limiting space.

[0087] As one implementation method, with Figure 8 For example, the illustration shows two symmetrically arranged first mounting limiting parts s1 located on the side of the mounting member 120 away from the projector body. The first mounting limiting part s1 includes a first sub-limiting part s11 and a second sub-limiting part s12. One end of the first sub-limiting part s11 connects to the side of the mounting member 120 away from the projector body, and the other end connects to the second sub-limiting part s12. The cross-section of the first mounting limiting part s1 is approximately L-shaped and extends along the first direction F1. The connecting parts 132b of the two rotating members 132 can be inserted relative to each other into the limiting space along the first direction F1. The two second sub-limiting parts s12 can... Figure 8 The connecting portion 132b of the rotating member 132 is limited in the vertical direction as shown in the diagram, and the two first sub-limiting portions s11 can be... Figure 8 The connecting portion 132b of the rotating member 132 is limited in the left-right direction as shown in the diagram. Of course, in another embodiment, Figure 8 The two illustrated second sub-limiting portions s12 can also be connected together. In another embodiment, first mounting limiting portions s1 can be provided respectively, corresponding one-to-one with the connecting portions 132b of the two rotating members 132, thus forming two different limiting spaces. Of course, it is also possible to... Figure 8 The illustration shows that the connecting portions 132b of the two rotating members 132 are inserted at different positions within the same limiting space. This can be configured according to specific implementations, and the embodiments of this application do not impose specific limitations on this.

[0088] Therefore, by setting the first installation limiting part s1 to form a limiting space, the connecting part 132b of the rotating member 132 can be inserted into the limiting space, thereby limiting the rotating member 132 to the mounting member 120.

[0089] For specific implementation details, please refer to [link / reference]. Figure 1 and Figure 2 and in conjunction with reference Figures 6 to 8The first mounting limiting part s1 can be used to engage the connecting part 132b of the rotating member 132 to achieve relative fixation between the rotating member 132 and the mounting member 120. Furthermore, through holes (not shown in the figure) can be provided on the connecting part 132b and the mounting member 120 respectively, and the connector passes through the corresponding through hole to securely connect the connecting part 132b and the mounting member 120. That is, before securing the connecting part 132b and the mounting member 120, the first mounting limiting part s1 can limit the connecting part 132b to the mounting member 120 to facilitate the subsequent installation of the connector.

[0090] Thus, the assembly method illustrated in some of the above embodiments can be flexibly set to further improve the assemblability and reliability of the connection between the rotating part 132 and the mounting part 120.

[0091] In some embodiments, please continue to refer to Figure 7 and Figure 8 The mounting component 120 is further provided with a second mounting limiting part s2. At least a portion of the second mounting limiting part s2 is located within the limiting space, and is used to limit the connecting part 132b in the first direction F1. Figure 8 For example, the illustration shows the second mounting limiting part s2 completely located within the limiting space, and the second mounting limiting part s2 can limit the connecting parts 132b on both sides. The number and position of the second mounting parts g2 can be set according to the mounting position of the two connecting parts 132b, and this embodiment does not impose specific limitations on this.

[0092] Thus, when the connecting part 132b is inserted into the limiting space, the second mounting limiting part s2 enables the connecting part 132b to be limited to the required mounting position relative to the mounting member 120.

[0093] In some embodiments, please continue to refer to Figures 6 to 8 The mounting component 120 includes a first sub-mounting component 121 for connecting to the projector body, and a second sub-mounting component 122 for connecting to the first sub-mounting component 121. The second sub-mounting component 122 has a receiving cavity r and two openings k2 respectively communicating with the receiving cavity r. The two openings k2 are arranged opposite to each other along a first direction F1, and each rotating component 130 corresponds to one opening k2. The support component 131 can extend into the receiving cavity r through the corresponding opening k2. The receiving cavity r is used to provide clearance space for the support component 131 when the rotating component 132 rotates.

[0094] As one implementation method, please continue to refer to Figures 6 to 8In conjunction with the first mounting limiting part s1 and the second mounting limiting part s2 illustrated in the aforementioned embodiments, the second sub-mounting member 122, the first mounting limiting part s1, and the second mounting limiting part s2 are mounted on the side of the first sub-mounting member 121 facing away from the projector body. The first mounting limiting part s1 and the second mounting limiting part s2 are located within the receiving cavity r. That is, the limiting space formed by the first mounting limiting part s1 is also located within the receiving cavity r. When the second mounting part g2 is completely located within the limiting space, the support assembly 131 located within the receiving cavity r can also be offset.

[0095] Furthermore, please continue to refer to Figure 6 A recessed groove 1211 can be provided on the side of the first sub-mount 121 opposite to the second sub-mount 122. A through hole is provided at the bottom of the recessed groove 1211 so that the connector can securely connect the connecting part 132b and the first sub-mount 121. This facilitates the connection of the first sub-mount 121 to the projector body.

[0101] Figure 10 It shows Figure 1 A schematic diagram of the structure of the base 110 in the base 100 shown; Figure 11 It shows Figure 10 The diagram shows the structure of the seat 110 from another perspective; for ease of explanation, only the content related to the embodiments of this application is shown.

[0102] In some embodiments, please refer to Figure 2 , Figure 10 and Figure 11 The base 100 also includes a buffer 150, which is located on the side of the seat 110 opposite to the rotating assembly 130. For example, the buffer 150 can be made of a material with cushioning properties, such as rubber or silicone. Furthermore, two buffers 150 can be provided, symmetrically arranged on the seat 110. This can improve the stability of the seat 110 when placed in the target position.

[0103] In some embodiments, please refer to Figure 10 and Figure 11 The seat 110 has a mounting groove g on the side opposite to the rotating assembly 130, and a portion of the buffer 150 is accommodated within the mounting groove g. The shape and number of the mounting groove g are adapted to the buffer 150 and can be set according to actual usage; this embodiment does not impose specific limitations on this. This facilitates the installation and replacement of the buffer 150.

[0104] Figure 12 A schematic diagram of the structure of the projector 10 in one embodiment of this application is shown; Figure 13 It shows Figure 12 The diagram shows a partial exploded structure of the projector 10; for ease of explanation, only the content related to the embodiments of this application is shown.

[0105] Based on the same inventive concept, this application also provides a projector 10, including a projector body and a base 100 as in any of the above embodiments, with a mounting member 120 connecting the projector body. Figure 12 and Figure 13For example, the bottom of the housing 200 of the projector 10 is provided with a mating groove 210, and the mounting part 120 of the base 100 can be installed in the mating groove 210 by means of screws 300. Of course, the mounting part 120 of the base 100 can also be connected to other components inside the housing 200, and this embodiment does not specifically limit this. Since the projector 10 includes the base 100 in any of the above embodiments, the projector 10 also has the advantages of the base 100, which will not be described again here.

[0106] In summary, in the base 100 and projector 10 provided in this application embodiment, the base 100 includes at least a seat 110, a mounting member 120, and two rotating components 130. By arranging the two rotating components 130 opposite each other on both sides of the mounting member 120 along the first direction F1, the rotating components 130 are divided into two parts, which facilitates the assembly of the rotating components 130 from both sides of the mounting member 120, and then the rotating components 130 are installed onto the seat 110. By setting the rotating component 130 to a structure including a support component 131 and a rotating member 132, the support component includes a fastening component 131c and a limiting component 131d. The fastening force can be adjusted by means of the fastening component 131c, and the required rotation range of the rotating member 132 can be set by means of the limiting component 131d, so that the rotation process of the rotating member 132 can be controlled as needed, making it more stable. By setting the rotating component 132 as an approximately L-shaped member and correspondingly setting a limiting structure on the mounting component 120, the assemblability and stability during movement of the rotating component 132 are further improved. The cover 140 enhances the aesthetics of the projector 10, and the corresponding foolproof structure further facilitates assembly. Thus, the various components in the base 100 cooperate with each other, simplifying the overall structure of the base 100, reducing its structural complexity, improving assemblability, and enhancing the user experience.
