Description

Technical Field

[0001] This utility model relates to the field of projection equipment technology, specifically to a projector device with a built-in TV stick (Dongle). Background Technology

[0002] With the increasing popularity of smart TV sticks (such as Android TV Dongles), integrating them into projectors to enhance their intelligence and content access capabilities has become a common practice. Currently, there are two main methods for integrating projectors and TV sticks:

[0003] External connection: The TV stick is installed on the outside of the projector, usually connected to the corresponding terminals on the projector's motherboard via a mini HDMI cable and a micro-USB cable. The main disadvantage of this method is that the TV stick is completely exposed, which not only affects the overall aesthetics of the projector, but also makes the exposed cables and interfaces susceptible to physical damage or dust accumulation, leading to reduced reliability.

[0004] Built-in connection: To address the aesthetic issues of external designs, existing technologies attempt to integrate the TV stick into the projector casing. However, the connection method still relies on mini HDMI and micro-USB cables. Specifically, the TV stick is typically secured via an ATV adapter plate and then connected to the mainboard terminals via the aforementioned cables. This built-in method has significant inherent drawbacks:

[0005] Because the signal needs to be relayed through a long mini HDMI cable and possibly an ATV adapter, the video and audio signals are easily attenuated during transmission, affecting the output quality.

[0006] The entire connection chain involves multiple interfaces (TV stick interface, interfaces at both ends of the cable, motherboard terminal interface, and adapter board interface) and multiple cable segments. This complex connection structure greatly increases the probability of poor port contact. Once poor contact occurs, it will directly cause the TV stick to be unrecognized or have no signal output, seriously affecting user experience and product reliability.

[0007] Longer cables are cumbersome to run and secure in a limited space, and the small size of the mini HDMI interface requires very high precision in installation position; even slight carelessness can easily lead to an unstable connection.

[0008] In summary, whether external or internal, current technologies generally rely on mini HDMI and micro-USB cables for connection. This cable-based connection method is the root cause of core problems such as poor signal stability, high failure rate due to poor contact, and complex installation in built-in TV stick solutions. Signal attenuation and frequent signal loss have become common problems plaguing the market application of built-in TV stick projectors, urgently requiring a more reliable and simpler integrated structure solution to address these technical challenges. Utility Model Content

[0009] (a) Technical problems to be solved

[0010] This utility model addresses the above-mentioned problems by proposing a projector device with a built-in TV stick (Dongle). The purpose is to solve the problems of signal attenuation, poor port contact, and complex installation caused by the reliance on wired connections in existing projector-built-in TV sticks (Dongles), and to ensure stable and reliable signals and a secure connection.

[0011] (II) Technical Solution

[0012] To achieve the above objectives, this utility model provides a projector device with a built-in TV stick (Dongle), comprising:

[0013] The housing has an internal mounting slot for accommodating the TV stick dongle;

[0014] The motherboard is fixed inside the housing, and an HDMI terminal is provided on its edge, with the HDMI terminal's connector facing the side opening of the mounting slot.

[0015] The side wall of the mounting slot is provided with ribs, which are configured to form a fixed structure for the HDMI interface of the TV stick Dongle and the HDMI terminal of the motherboard to form a wire-free plug-in connection.

[0016] The cover, secured to the top of the housing with screws, encloses the TV stick dongle within the mounting slot.

[0017] Furthermore, the bottom surface of the mounting groove is provided with a long strip-shaped limiting rib to limit the vertical installation height of the TV stick Dongle.

[0018] Furthermore, the sidewall of the mounting groove is provided with an array of heat dissipation vents, which are directly opposite the heat dissipation holes that connect the housing to the outside.

[0019] Furthermore, the inclined angle of the oblique rib is 15°-45°, forming an insertion guide surface.

[0020] Furthermore, the number of the elongated limiting ribs is two, and they are arranged in parallel.

[0021] Furthermore, the mating surface between the lid and the housing is provided with a sealing groove.

[0022] Furthermore, the rib is an oblique rib, which is configured to guide the TV stick dongle vertically into the mounting groove along a predetermined trajectory.

[0023] (III) Beneficial Effects

[0024] Compared with existing technologies, the projector device with a built-in TV stick dongle provided by this utility model eliminates all connecting cables and ATV adapter boards, designing the HDMI interface of the TV stick dongle and the HDMI terminal of the motherboard as a direct physical plug-in structure without intermediaries. Specifically, the HDMI interface of the TV stick dongle is directly inserted into the HDMI terminal of the motherboard, and the signal transmission path no longer passes through cables or adapter boards, completely avoiding signal attenuation caused by cable impedance and adapter circuits. The ribs on the side wall of the mounting slot precisely constrain the insertion position of the TV stick dongle, ensuring that its HDMI interface is aligned with the motherboard terminal and avoiding contact failure caused by misalignment. The HDMI terminal itself has high reliability plugging performance, and combined with the longitudinal fixation of the dongle by the ribs and the lateral locking of the cover (by countersunk screws), a three-dimensional mechanical constraint is formed, eliminating the risk of loosening during use. The TV stick dongle only needs to be pushed into the mounting slot along the rib guide to complete the plugging, and then the cover is locked. No wiring or adapter operations are required throughout the process, improving installation efficiency and eliminating manual wiring errors. Attached Figure Description

[0030] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0031] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1-4 As shown, this utility model provides a projector device with a built-in TV stick (Dongle), including: a housing 1, a main board 4, a cover 3, an HDMI terminal 5, and screws. The TV stick (Dongle 2) is precisely positioned and installed through a mounting groove 101 designed inside the housing 1. The side opening of the mounting groove 101 is aligned with the HDMI terminal 5 connector located on the edge of the main board 4. During assembly, the TV stick (Dongle 2) is pushed in along the side opening of the mounting groove 101, and its HDMI interface is directly inserted into the HDMI terminal 5 of the main board 4 to form a wireless connection. At the same time, the ribs 103 on the side wall of the mounting groove 101 abut against the main body of the TV stick (Dongle 2) to ensure that the device does not shift after insertion. Finally, the cover 3 is placed on top of the housing 1 and secured with countersunk screws ST2.3×6mm, so that the TV stick (Dongle 2) is completely enclosed in the mounting groove 101. This structure eliminates the need for traditional mini HDMI cables and adapter boards. Through the combination of physical limiting ribs and a direct-plug interface, it simplifies the assembly process (requiring only two steps: pushing in the locking cover) and eliminates the risk of signal attenuation and poor port contact. At the same time, the large size tolerance of the standard HDMI terminal 5 further ensures the tightness of the connection and long-term reliability.

[0034] Preferably, such as Figure 3 As shown, the ribs 103 on the side wall of the mounting slot 101 are slanted ribs. The slanted ribs naturally guide the TV stick Dongle 2 to slide into the mounting slot 101 along the set inclined path, and finally accurately position it to be horizontally aligned with the HDMI terminal 5 of the motherboard 4, effectively eliminating the offset when manually inserted.

[0035] Preferably, such as Figure 3 As shown, several long strip-shaped limiting ribs 104 extend from the bottom of the mounting slot 101. When the TV stick Dongle 2 slides into the mounting slot 101, the long strip-shaped limiting ribs 104 will precisely abut against the bottom surface of the TV stick Dongle 2, thereby firmly restricting the TV stick Dongle 2 at the preset vertical height position, ensuring that the TV stick Dongle 2 interface and the HDMI terminal 5 of the motherboard 4 always remain fully engaged.

[0036] In some embodiments, the number of elongated limiting ribs 104 is two, and they are arranged in parallel.

[0037] Preferably, such as Figure 2 As shown, the side wall of the mounting slot 101 is arranged with an array of heat dissipation vents 102. These heat dissipation vents 102 are precisely aligned with the external heat dissipation holes on the housing 1, so that the heat generated by the TV stick Dongle2 during operation can be discharged to the outside without obstruction along a straight channel, forming an efficient heat dissipation path.

[0038] Preferably, the diagonal ribs extend at an angle of 15° to 45° to form a smooth guide slope. When the TV stick Dongle 2 is pushed into the mounting slot 101, the edge of its outer shell 1 will naturally slide down the slope, automatically guiding the TV stick Dongle 2 to the insertion position that is precisely aligned with the HDMI terminal 5 of the motherboard 4.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
