[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please refer to this as well. Figures 1 to 4 This utility model provides a screen projector, which includes:

[0032] The transmitter 10 is provided with a first interface 11 that at least partially protrudes from the transmitter 10;

[0033] The receiver 20 is provided with a second interface 21 that at least partially protrudes from the receiver 20;

[0034] The transmitter 10 and receiver 20 are separate units that can be connected as one unit. When the transmitter 10 and receiver 20 are connected as one unit, the first interface 11 of the transmitter 10 enters the receiver 20, and the second interface 21 of the receiver 20 enters the transmitter 10.

[0035] The transmitter 10 and receiver 20 each integrate relevant electronic components. The first interface 11 is electrically connected to the relevant electronic components inside the transmitter 10, and the second interface 21 is electrically connected to the relevant electronic components inside the receiver 20. When using the projector, the transmitter 10 and receiver 20 are separated and connected to their respective devices via the first interface 11 and the second interface 21. When not in use, the transmitter 10 and receiver 20 are connected as a single unit, resulting in a small overall footprint and easy portability.

[0036] Specifically, in this embodiment, the transmitter 10 and receiver 20 are roughly hemispherical in shape. When the transmitter 10 and receiver 20 are connected as a single unit, the overall shape is ellipsoidal, thereby reducing space occupation. The transmitter 10 and receiver 20 can also be hemispherical or cuboid in shape, etc.

[0037] In some embodiments, the transmitter 10 and the receiver 20 are detachably connected via a magnetic, snap-fit, or rotary lock structure.

[0038] When connected by a magnetic, snap-on, or rotary lock structure, the transmitter 10 and receiver 20 can not only be quickly connected as one unit, but also be easily separated when using the screen projector, making operation convenient.

[0039] The snap-fit ​​structure may include a slot and a protruding edge. One of the transmitter 10 and receiver 20 has a slot, and the other has a corresponding protruding edge. The connection between the transmitter 10 and receiver 20 is achieved by the engagement of the slot and the protruding edge. The following explanation uses an example where the transmitter 10 has a slot and the receiver 20 has a corresponding protruding edge. Specifically, the slot is an annular groove located on the side of the transmitter 10 that mates with the receiver 20, near the edge of the transmitter 10. The protruding edge is also an annular structure, located on the side of the receiver 20 that mates with the transmitter 10, near the edge of the receiver 20. When the transmitter 10 and receiver 20 are connected, the protruding edge enters the slot. By applying external force and pressing, the protruding edge and slot can be fully engaged, achieving a secure connection between the transmitter 10 and receiver 20. When it is necessary to separate the transmitter 10 and the receiver 20, an external force is applied to disengage the protrusion from the slot, and the protrusion and the slot are no longer engaged, thus achieving the separation of the transmitter 10 and the receiver 20.

[0040] A twist-lock structure is adopted, allowing the transmitter 10 and receiver 20 to be connected and disconnected via rotation. In one embodiment, the twist-lock structure includes internal and external threads. One of the transmitter 10 and receiver 20 has an internal thread, and the other has a corresponding external thread. The connection between the transmitter 10 and receiver 20 is achieved through the engagement of the internal and external threads. In another embodiment, the twist-lock structure may include a connecting pin and a receiving groove. Both the connecting pin and the receiving groove are arc-shaped structures. One of the transmitter 10 and receiver 20 has a connecting pin, and the other has a receiving groove. When the transmitter 10 and receiver 20 are connected, one end of the connecting pin aligns with the inlet of the receiving groove, causing the transmitter 10 and receiver 20 to rotate relative to each other. The connecting pin then rotates into the receiving groove, and the interference fit between the connecting pin and the receiving groove prevents the connecting pin from easily disengaging from the receiving groove, thereby achieving the connection between the transmitter 10 and receiver 20. When it is necessary to separate the transmitter 10 and the receiver 20, an external force is applied to make the transmitter 10 and the receiver 20 rotate relative to each other, so that the connecting pin is disengaged from the receiving groove, and the transmitter 10 and the receiver 20 can be separated.

[0041] In this embodiment, the transmitter 10 and the receiver 20 are connected via a magnetic structure. Using a magnetic structure eliminates the need for precise alignment; the transmitter 10 and receiver 20 can be quickly and easily connected using only magnetic force, supporting blind operation and improving the user experience.

[0042] In some embodiments, please refer to the following: Figures 1 to 3 The magnetic structure includes a first magnet 12 disposed in the transmitter 10 and a second magnet disposed in the receiver 20. When the transmitter 10 and the receiver 20 are close to each other, the first magnet 12 and the second magnet are attracted to each other.

[0043] Specifically, the first magnet 12 and the second magnet are correspondingly arranged. When the transmitter 10 and the receiver 20 are connected as a whole, as the transmitter 10 and the receiver 20 approach each other, the first magnet 12 of the transmitter 10 and the second magnet of the receiver 20 are attracted to each other, thus achieving integration. When the transmitter 10 and the receiver 20 are separated, the separation force is made greater than the attraction force between the first magnet 12 and the second magnet, so that the transmitter 10 and the receiver 20 can be quickly separated.

[0044] The number of the first magnet 12 and the second magnet can be set according to actual needs, and there is no specific limitation. For example, the first magnet 12 can be set to two. The two first magnets 12 are distributed on the upper and lower sides of the transmitter 10. When the transmitter 10 is connected to the receiver 20, the two first magnets 12 and the two second magnets are attracted to each other.

[0045] It is understandable that when the transmitter 10 and receiver 20 are connected only by a magnetic structure, although it is convenient to separate the transmitter 10 and receiver 20, they are also prone to accidental separation. Therefore, while the transmitter 10 and receiver 20 are connected by a magnetic structure, they can also be connected by a snap-fit ​​structure at the same time, thereby improving the connection tightness between the transmitter 10 and receiver 20.

[0046] In some embodiments, please refer to the following: Figures 1 to 2 The transmitting end 10 is provided with a first guide groove 13 for the second interface 21 to be inserted, and the receiving end 20 is provided with a second guide groove for the first interface 11 to be inserted.

[0047] The first interface 11 protrudes at least partially from the transmitter 10, and the second interface 21 protrudes at least partially from the receiver 20. When the transmitter 10 and receiver 20 are connected, the first interface 11 is inserted into the second guide groove, and the second interface 21 is inserted into the first guide groove 13. By setting the first guide groove 13 and the second guide groove, the connection between the transmitter 10 and the receiver 20 can be guided. As the first interface 11 slides along the second guide groove and the second interface 21 slides along the first guide groove 13, it is ensured that the first magnet 12 of the transmitter 10 can accurately dock and attract with the second magnet of the receiver 20.

[0048] In some embodiments, please refer to the following: Figures 1 to 4 The second interface 21 has the same structure as the first interface 11. The first interface 11 includes a USB interface 111 and a Type-C interface 112 that can be switched between each other.

[0049] USB 111, short for Universal Serial Bus, is an external bus standard used to regulate the connection and communication between computers and external devices. It includes various physical interface forms; the Type-C interface 112 is one such form, belonging to the USB Type-C standard, supporting reversible plugging, and widely used in smartphones, computers, and other devices.

[0050] Both the first interface 11 and the second interface 21 include a USB interface 111 and a Type-C interface 112 that can be switched between each other. This configuration allows the user to select the appropriate interface based on the actual situation of the device to be connected, improving the adaptability of the screen projector during connection and use, avoiding the need for additional adapter cables due to a single interface, and improving the user experience.

[0051] In some embodiments, please refer to the following: Figures 1 to 4 The shape and size of the first guide groove 13 and the second guide groove are adapted to the shape and size of the USB interface 111.

[0052] In some embodiments, please refer to the following: Figures 1 to 4 The Type-C interface 112 is connected to the transmitter 10 / receiver 20 via the data cable 14, and the USB interface 111 is pluggably located on the Type-C interface 112.

[0053] The USB interface 111 can be plugged into the Type-C interface 112. The transmitter 10 and receiver 20 can choose between the USB interface 111 or the Type-C interface 112 as needed. When using the USB interface 111, simply connect it directly. When using the Type-C interface 112, first unplug the USB interface 111 from the Type-C interface 112, then connect it to the Type-C interface 112. After use, simply plug the USB interface 111 back into the Type-C interface 112. Switching is convenient.

[0054] In some embodiments, both the transmitter 10 and the receiver 20 are provided with an elastic winding mechanism, the elastic winding mechanism comprising:

[0055] A rotatable shaft has a through hole at its center for the data cable 14 to pass through;

[0056] A flexible energy storage component is fixedly mounted on the rotating shaft;

[0057] When the data cable 14 is pulled out, the data cable 14 drives the rotating shaft to rotate, and the elastic energy storage component deforms and stores energy. After the energy is released, the elastic energy storage component drives the rotating shaft to reverse so that the data cable 14 automatically rewinds to the tightened state.

[0058] By setting up an elastic winding mechanism, the data cable 14 can be pulled out from the transmitter 10 and receiver 20, thus adapting to scenarios where it is inconvenient for the transmitter 10 and receiver 20 to be directly connected via the USB interface 111 or the Type-C interface 112. By pulling out the data cable 14, the USB interface 111 and the Type-C interface 112 can move freely, facilitating connection with devices.

[0059] In practical use, as the data cable 14 is pulled out, the data cable 14 drives the shaft to rotate. The rotation of the shaft causes the elastic energy storage component to deform and store energy. When the external force disappears and the data cable 14 is released, the elastic energy storage component drives the shaft to rotate in the opposite direction. The reverse rotation of the shaft causes the data cable 14 to automatically rewind and wrap around the shaft.

[0060] It is understandable that the transmitter 10 and receiver 20 are provided with openings for the data cable 14 to move. The size of the openings is smaller than the size of the USB interface 111 and the Type-C interface 112. Therefore, when the shaft reverses and drives the data cable 14 to automatically rewind, the USB interface 111 and the Type-C interface 112 will not enter the interior of the transmitter 10 and receiver 20.

[0061] In some embodiments, the elastic energy storage element is a helical coil spring or a spiral spring.

[0062] When the elastic energy storage component uses a helical coil spring, as the data cable 14 is pulled out, the rotation of the shaft causes the helical coil spring to undergo torsional deformation. The helical coil spring stores torque, and after releasing the external force, the torque drives the shaft to reverse, thereby realizing the automatic rewinding of the data cable 14.

[0063] When the elastic energy storage component uses a spiral spring, the spiral spring is initially in a relaxed state. As the data line 14 is pulled out, the rotation of the shaft causes the spiral spring to undergo planar coiling deformation to store bending potential energy. After the external force is released, the curvature of the spiral spring is restored, driving the shaft to reverse and realizing the automatic rewinding of the data line 14.

[0064] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0065] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
