DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] In the embodiment of the present invention, a screen projection device is provided. Please refer to Figure 1-Figure 3The projection device includes a transmitting mechanism 10 and a receiving mechanism 20. The transmitting mechanism 10 includes a transmitting body 110 and a connector 120 arranged on the transmitting body 110. The connector 120 is used to insert a mobile device so that the transmitting body 110 receives information from the mobile device. The receiving mechanism 20 includes a receiving body 210 and an interface 230 and a receiving hole 220 arranged on the receiving body 210. The interface 230 is used to be electrically connected to the display device. The receiving body 210 is used to receive the signal wirelessly transmitted by the transmitting body 110 and transmit the signal to the display device. The receiving hole 220 is used to store the connector 120.

[0031] According to the screen projection device in the above embodiment, the receiving mechanism 20 is always connected to the projection display. When the connector 120 of the transmitting mechanism 10 is needed, the connector 120 is inserted into the data interface 230 of the mobile device, and the transmitting body 110 receives information from the mobile device. The transmitting body then transmits the received information to the receiving mechanism 20 by remote wireless means, and the receiving body 210 of the receiving mechanism 20 passes the information to the projection display. When the screen projection is not needed, the connector 120 of the transmitting mechanism 10 can be inserted into the receiving hole 220 of the receiving mechanism 20, so as to achieve the purpose of assembling the transmitting mechanism 10 and the receiving mechanism 20 together. In this way, the transmitting mechanism 10 and the receiving mechanism 20 are placed in pairs, and the loss of one of the components will not occur. The screen projection device implemented in the utility model can solve the problem that the split screen projection device is easy to lose parts.

[0032] In this embodiment, the connector 120 inserted into the receiving hole 220 can also protect the connector 120. The connector 120 is stored in the receiving hole 220 to prevent the interface 230 from being damaged and contaminated with dust. Specifically, the connector 120 can be adapted to a type-C interface, a USB interface, and the like.

[0033] It should be noted that in order to further increase the tightness of the connection between the launching mechanism 10 and the receiving mechanism 20, a matching buckle structure can be provided on the receiving body 210 and the launching body 110, so that the launching mechanism 10 and the receiving mechanism 20 are not easily disassembled after being combined.

[0034] Alternatively, magnets with opposite magnetic poles are provided on the receiving body 210 and the transmitting body 110, and the connection between the transmitting mechanism 10 and the receiving mechanism 20 is made tighter through the mutual attraction of the magnets.

[0035] In some specific embodiments, the receiving hole 220 and the joint 120 are interference fit.

[0036] In this embodiment, the interference fit between the receiving hole 220 and the joint 120 ensures the tightness of the launching mechanism 10 and the receiving mechanism 20 when they are stored together.

[0037] In some specific embodiments, a buffer pad 130 is further included. The buffer pad 130 is disposed on the transmitting body 110 . When the connector 120 is inserted into the receiving hole 220 , the buffer pad 130 abuts against the receiving body 210 .

[0038] The cushion 130 can absorb shock and vibration and protect the internal items from damage. The cushion 130 can be made of various materials, including foam, silicone, rubber, plastic, cloth, etc., and a suitable material can be selected according to the requirements of a specific application.

[0039] In this embodiment, the buffer pad 130 can ensure that the launch mechanism 10 and the receiving mechanism 20 do not collide with each other. The buffer pad 130 can also increase the friction between the launch body 110 and the receiving body 210, so that the launch body 110 and the receiving body 210 are not easy to separate after being combined.

[0040] In some specific embodiments, a first button 140 is further provided on the transmitting body 110 .

[0041] The first button 140 can be set to control the switch of the transmitting body 110. Generally, the transmitting body 110 includes a transmitting circuit board. The first button 140 is generally electrically connected to the transmitting circuit board, and the transmitting circuit board is driven to transmit information by pressing the first button 140.

[0042] In some specific embodiments, a second button 240 is further provided on the receiving body 210 .

[0043] Similarly, the receiving body 210 includes a receiving circuit board, which wirelessly receives signals and transmits them to the projection display. The second button 240 mainly plays the role of switching the receiving circuit board, thereby preventing the receiving mechanism 20 from consuming power for a long time.

[0044] In some specific embodiments, an energy storage unit (not shown) is further disposed in the transmitting body 110 , and a power interface 150 is disposed on the surface of the transmitting body 110 , and the power interface 150 is electrically connected to the energy storage unit.

[0045] In this embodiment, a power interface 150 is provided on the surface of the transmitting body 110 , and the energy storage unit in the transmitting body 110 is charged by plugging a charging cable into the power interface 150 .

[0046] In some specific embodiments, the transmitting body 110 is further provided with a wearing hole 160 .

[0047] Generally speaking, the receiving mechanism 20 always remains connected to the projection display and does not need to be moved, so the probability of loss is very small. As for the transmitting mechanism 10, it needs to match different mobile devices and is always in the process of moving, so a wearing hole 160 is required. A rope can be passed through the wearing hole 160 to achieve the purpose of hanging the transmitting mechanism 10.

[0048] In some specific embodiments, the receiving body 210 is further provided with an indicator light 250 .

[0049] In this embodiment, the power supply on the receiving body 210 usually comes from the projection display, and the design of the indicator light 250 allows the user to clearly know whether the projection display has been properly connected.

[0050] In some specific embodiments, the receiving body 210 and / or the transmitting body 110 are further provided with heat dissipation holes 12 .

[0051] Since both the receiving body 210 and the transmitting body 110 have power, the heat dissipation holes 12 are generally required to dissipate heat to prevent damage to the electronic components inside.

[0052] In some specific embodiments, please refer to Figure 3 and Figure 4 The receiving hole 220 is further provided with a stopper 2210, and the stopper 2210 abuts against the transmitting body 110 to prevent the head of the connector 120 from abutting against the inner wall of the receiving body.

[0053] In this embodiment, the connector 120 needs to be protected, otherwise the connection between the connector 120 and the mobile device will not be smooth. The stopper 2210 can prevent the connector 120 from completely touching the inner wall of the receiving hole 220, which is equivalent to making the end of the connector 120 away from the transmitting body 110 suspended in the air.

[0054] Finally, it should be noted that the wireless transmission of the screen projection device is mainly achieved through several technologies, including AirPlay, Miracast, DLNA, private screen projection protocols, and HDMI transmitter wireless screen projection.

[0055] AirPlay is a wireless technology developed by Apple that allows iOS devices to project content to AirPlay-enabled devices, such as Apple TV, via Wi-Fi. AirPlay supports two modes: push casting and mirror casting.

[0056] Miracast is a wireless display technology standard certified by the Wi-Fi Alliance, based on Wi-Fi Direct technology, and supports Android and Windows devices. It can achieve screen mirroring and transmit device screen content to the display device in real time, but it may be interfered with and cause image quality problems.

[0057] DLNA (Digital Living Network Alliance) is a push-mode screen projection technology, mainly used in home theater environments. It pushes content to large-screen devices for playback in the form of URLs, with lossless image quality but high network requirements.

[0058] Private screen projection protocols are customized protocols by some screen projection device manufacturers, such as the BJcast protocol. These protocols are customized according to manufacturer needs and have flexible functions.

[0059] HDMI transmitter wireless screen projection is to obtain the signal from the HDMI interface of the device through the HDMI transmitter, compress and encode it, and then transmit it wirelessly to the receiving end. This method is mainly based on the WHDI or WirelessHD protocol, but the transmitting device needs to have an HDMI output interface.

[0060] Each technology has its advantages and applicable scenarios. When choosing a screen projection solution, users need to make a choice based on device compatibility, network environment and usage requirements.

[0061] Finally, it should be noted that the display device may be a liquid crystal display, a light emitting diode, a plasma display, a projector, a touch screen, etc. Specifically, it may be a television, a mobile phone, a computer, a tablet computer, etc.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
