Description

Technical Field

[0001] This utility model relates to the field of screen projector technology, specifically to a screen projector that combines a transmitter and a receiver. Background Technology

[0002] A screen mirroring device is used to share information from electronic devices to a display screen. The screen mirroring device includes a transmitter and a receiver. The transmitter is connected to the electronic device via a cable, and the receiver is plugged into the display screen. The transmitter and receiver communicate with each other via a network to transmit signals, thus enabling the wireless projection of information from electronic devices onto the display screen for sharing.

[0003] Currently, in existing technologies, the transmitter and receiver of a screen mirroring device are two independent components. The transmitter and receiver are placed separately and are plugged into the electronic device and the display screen respectively during use. This can lead to a situation where one of the transmitter or receiver is lost or cannot be found immediately, thus preventing timely screen mirroring.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a combined transmitter and receiver screen projector to solve the above-mentioned technical problems. The technical solution adopted by this utility model is as follows: A transmitter and receiver combined projection device includes a transmitter and a receiver. The transmitter includes a transmitting component installed inside a transmitting housing. An assembly cavity is also provided on the transmitting housing. The assembly cavity has an entrance located on the surface of the transmitting housing. The receiver is inserted into the assembly cavity along the entrance, and the end of the receiver closes the entrance. A snap-fit ​​structure is also provided between the receiver and the assembly cavity to lock the receiver inside the assembly cavity.

[0006] Furthermore, the snap-fit ​​structure includes a snap-fit ​​block slidably disposed on the receiver, the snap-fit ​​block having a snap-fit ​​end that elastically extends out of the receiver, and a snap-fit ​​groove formed above the interior of the assembly cavity for the snap-fit ​​end to snap into therein.

[0007] Furthermore, the receiver includes a receiving component assembled inside the receiving housing. The receiving housing also has a sliding groove for the card block to slide within it. The sliding groove has a first elastic member inside it. The two ends of the first elastic member abut against the bottom of the sliding groove and the end of the card block away from the locking end, respectively, to elastically push the locking end out of the receiving housing.

[0008] Furthermore, a toggle end is formed on the surface of the card block, and a limiting groove is provided on the receiving shell for the toggle end to protrude and slide within it.

[0009] Furthermore, an elastic top contact is provided at the bottom of the assembly cavity. After the receiver is housed in the assembly cavity, the receiver abuts against the elastic top contact and compresses the elastic top contact. After the snap-fit ​​structure is released, the elastic top contact elastically pushes the receiver out.

[0010] Furthermore, the elastic top contact member includes a top contact plate and a second elastic member. The top contact plate is slidably connected within the assembly cavity along the length direction of the assembly cavity, and the second elastic member is disposed between the top contact plate and the bottom of the assembly cavity.

[0011] Furthermore, the top contact plate includes a plate and a leg integrally formed with the plate, the leg being slidably connected within the assembly cavity, and the second elastic member being fitted onto the leg.

[0012] Furthermore, a positioning plate is also provided inside the assembly cavity. Along the depth direction of the assembly cavity, the positioning plate is located in front of the elastic top contact member, and a positioning groove adapted to the front end contour of the receiver is provided on the positioning plate, so that the front end of the receiver can pass through and be positioned.

[0013] The beneficial effects of this utility model are as follows: This utility model provides a transmitter and receiver combined screen sharing device. When screen sharing is not needed, the transmitter and receiver can be combined into a single unit. When screen sharing is required, the transmitter and receiver can be separated into two independent parts, which are electrically connected to the electronic device and the display screen respectively to complete the wireless transmission of signals for screen sharing. In this embodiment, an assembly cavity is provided on the outer shell of the transmitter to house the receiver. The receiver can be locked inside the assembly cavity through a snap-fit ​​structure between the assembly cavity and the receiver, thereby completing the combination of the receiver and transmitter. This avoids the need to combine the transmitter and receiver into a single unit for unified storage when screen sharing is not required, thus avoiding the situation where the two components need to be stored separately and are easily lost or cannot be found quickly.

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0022] Screen mirroring, also known as wireless screen mirroring or wireless screen sharing, uses wireless transmission technology to wirelessly connect a monitor and an electronic device, allowing the screen displayed on the electronic device to be displayed in real time on the screen of another device, thus achieving the purpose of screen sharing. It is widely used in teaching, conferences, and other venues.

[0023] This utility model embodiment provides a screen sharing device that combines a transmitter 100 and a receiver 200. When screen sharing is not needed, the transmitter 100 and receiver 200 can be combined into a single unit. When screen sharing is required, the transmitter 100 and receiver 200 can be separated into two independent parts, which are electrically connected to the electronic device and the display screen respectively to complete the wireless transmission of signals for screen sharing. In this embodiment, an assembly cavity 120 is provided on the outer shell of the transmitter 100 to house the receiver 200. Through a snap-fit ​​structure between the assembly cavity 120 and the receiver 200, the receiver 200 can be locked within the assembly cavity 120, thereby completing the combination of the receiver 200 and the transmitter 100. This avoids the need to combine the transmitter 100 and receiver 200 into a single unit for unified storage when screen sharing is not required, thus avoiding the situation where the two components need to be stored separately and are easily lost or cannot be found quickly.

[0024] Specifically, such as Figure 1-6 As shown in the figure, this utility model provides a combined screen projector with a transmitter 100 and a receiver 200. The transmitter 100 includes a transmitter assembly 111 installed inside a transmitter housing 110. When screen sharing is required, the transmitter 100 is electrically connected to the electronic device via a cable, and the receiver 200 is plugged into the display screen. The transmitter 100 and the receiver 200 are wirelessly connected using existing wireless transmission technology, thereby enabling the wireless transmission of information from the electronic device to the display screen for display, thus achieving sharing. In order to combine the receiver 200 and the transmitter 100 into a single unit, an assembly cavity 120 is provided on the transmitter housing 110. The assembly cavity 120 has an inlet 121 located on the surface of the transmitter housing 110. The receiver 200 is inserted into the assembly cavity 120 along the inlet 121, and the end of the receiver 200 closes the inlet 121. A snap-fit ​​structure is also provided between the receiver 200 and the assembly cavity 120 to lock the receiver 200 in the assembly cavity 120.

[0025] When screen sharing is not required, the receiver 200 passes through the inlet 121 and is inserted into the assembly cavity 120. The snap-fit ​​structure locks the receiver 200 within the assembly cavity 120, thus combining the transmitter 100 and receiver 200 into a single unit. This allows for unified storage of the screen sharing device, avoiding the need to store the transmitter 100 and receiver 200 separately, and preventing the loss or inability to quickly locate one component.

[0026] In this embodiment, as Figure 4-6 As shown, the snap-fit ​​structure includes a snap-fit ​​block 210 that is slidably disposed in the receiver 200. The snap-fit ​​block 210 has a snap-fit ​​end 211 that extends elastically out of the receiver 200. A snap-fit ​​groove 122 is formed on the inside of the assembly cavity 120 for the snap-fit ​​end 211 to snap into.

[0027] After the receiver 200 is placed inside the assembly cavity 120, the snap-fit ​​end 211 of the receiver 200 is snapped into the slot 122, thereby locking the receiver 200 inside the assembly cavity 120, thus completing the assembly of the receiver 200 and the transmitter 100, which is convenient for unified storage.

[0028] In this embodiment, the receiver 200 includes a receiving component 202 assembled inside the receiving housing 201. The receiving housing 201 is also provided with a sliding groove 203 for the locking block 210 to slide within it. The sliding groove 203 is provided with a first elastic member 204. The two ends of the first elastic member 204 abut against the bottom of the sliding groove 203 and the end of the locking block 210 away from the locking end 211, respectively, to elastically push the locking end 211 out of the receiving housing 201. The locking block 210 slides within the slide groove 203 under the elastic thrust of the first elastic member 204, thereby allowing the locking end 211 to elastically extend out of the receiving housing 201. This facilitates locking the receiver 200 within the mounting cavity 122 after the receiver 200 is placed within the mounting cavity 120, thus locking the receiver 200 within the mounting cavity 120. Simultaneously, after pushing the locking block 210 toward the first elastic member 204 and compressing the first elastic member 204, the locking end 211 retracts into the receiving housing 201 and disengages within the mounting cavity 122, thereby releasing the receiver 200 within the mounting cavity 120.

[0029] In this embodiment, in order to facilitate pushing the card block 210 and realize the separation of the card receiving end 211 and the card slot 122, a toggle end 212 is also formed on the surface of the card block 210, and a limiting groove 205 is also provided on the receiving shell 201 for the toggle end 212 to protrude and be limited to slide within it.

[0030] When it is necessary to unlock the receiver 200 within the assembly cavity 120, pushing the actuating end 212 compresses the first elastic element 204, thereby causing the locking block 210 to move within the slide groove 203 toward the first elastic element 204, thus disengaging the locking end 211 from the slot 122 and achieving the unlocking action. In this embodiment, the first elastic element 204 is constructed of a spring, which provides an elastic thrust to the locking block 210, causing the locking end 211 to elastically extend out of the receiver housing 201.

[0031] After releasing the snap-fit ​​structure, to facilitate the quick removal of the receiver 200 from the assembly cavity 120, as follows: Figure 4-6 As shown, an elastic contact 130 is also provided at the bottom of the assembly cavity 120. After the receiver 200 is housed in the assembly cavity 120, the receiver 200 abuts against the elastic contact 130 and compresses the elastic contact 130. After the locking structure is released, the elastic contact 130 elastically pushes the receiver 200 out. By providing the elastic contact 130, after the locking structure is released, the receiver 200 can be elastically pushed out of the assembly cavity 120 under the elastic thrust of the elastic contact 130, thus facilitating the removal of the receiver 200.

[0032] Specifically, the elastic top contact 130 includes a top contact plate 131 and a second elastic member 132. The top contact plate 131 is slidably connected within the assembly cavity 120 along the length direction of the assembly cavity 120, and the second elastic member 132 is disposed between the top contact plate 131 and the bottom of the assembly cavity 120.

[0033] After the receiver 200 is loaded into the assembly cavity 120, as the receiver 200 extends into the assembly cavity 120, the end of the receiver 200 abuts against the top contact plate 131 and gradually presses against the second elastic member 132. This causes the top contact plate 131 to overcome the elastic force of the second elastic member 132 and move towards the bottom of the assembly cavity 120 until the locking end 211 of the locking block 210 locks against the slot 122, locking the receiver 200 inside the assembly cavity 120. At this time, the second elastic member 132 is compressed and generates elastic potential energy. After the locking end 211 is disengaged from the slot 122, the elastic potential energy of the second elastic member 132 is released, thereby elastically pushing the receiver 200 out of the assembly cavity 120 through the top contact plate 131, making it convenient to remove the receiver 200 from the assembly cavity 120.

[0034] In this embodiment, as Figure 4 As shown, the top contact plate 131 includes a plate 1311 and legs 1312 integrally formed with the plate 1311. The legs 1312 are slidably connected within the assembly cavity 120, and the second elastic member 132 is fitted onto the legs 1312. In this embodiment, there are two legs 1312. The two legs 1312 enable the top contact plate 131 to slide stably within the assembly cavity 120, and the plate 1311 ensures that the top contact plate 131 and the end of the receiver 200 have a sufficiently large contact area, which allows the top contact plate 131 to maintain stable contact with the receiver 200 and reliably provide elastic thrust to the receiver 200, enabling it to be elastically pushed out within the assembly cavity 120.

[0035] In this embodiment, in order to ensure that the entire surface of the end of the receiver 200 can contact the top contact plate 131 when the receiver 200 is pushed out of or inserted into the assembly cavity 120, so as to avoid uneven force on the top contact plate 131 affecting its movement, and at the same time, to prevent the receiver 200 from tilting in the assembler and getting stuck in the assembly cavity 120, a positioning plate 140 is also provided in the assembly cavity 120. Along the depth direction of the assembly cavity 120, the positioning plate 140 is located in front of the elastic top contact member 130, and a positioning groove 141 adapted to the front end contour of the receiver 200 is provided on the positioning plate 140 for the front end of the receiver 200 to pass through and be positioned. During the process of placing the receiver 200 into the assembly cavity 120, the front end (i.e., the plug-in end) of the receiver 200 passes through the positioning groove 141 and is limited by the inner edge contour of the positioning groove 141 and the edge contour of the front end of the receiver 200. This ensures that when the receiver 200 enters the assembly cavity 120, the direction of movement of the receiver 200 remains parallel to the axial direction of the assembly cavity 120, avoiding tilting and ensuring smooth movement within the assembly cavity 120.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
