[0025] The embodiments of the present application provide a projection device and a wearable device, which are described in detail below.

[0026] Combined with reference Figure 1-8The projection device 100 provided in the embodiment of the present application includes a housing 10 and a projection module 20 .

[0027] The shell 10 is provided with a accommodating cavity 101, and the shell 10 includes a first wall 11, a second wall 12 and a third wall 13. The first wall 11, the second wall 12 and the third wall 13 can be set to be circular, elliptical, rectangular, polygonal, etc. It should be understood that the rectangular embodiment is not strictly limited to a quadrilateral with four right angles, but can be a chamfered rectangle with chamfers at the four corners or a rounded rectangle with rounded corners at the four corners. The rounded corners and chamfers are set at the four corners of the rectangle, and the influence on the overall rectangular morphology can be ignored. At the same time, it is beneficial to process processing and can prevent stress concentration. In some embodiments, the first wall 11, the second wall 12 and the third wall 13 can also be understood as a relative surface, the first wall 11 and the second wall 12 are arranged oppositely, and the third wall 13 is located between the first wall 11 and the second wall 12; the third wall 13 is provided with a light-transmitting window 131; and the projection module 20 is located in the accommodating cavity 101, and the light of the projection module 20 is configured to be emitted from the light-transmitting window 131; wherein, the third wall 13 is provided with a fixing portion 133, and the fixing portion 133 is located on a side of the third wall 13 away from the light-transmitting window 131, and the distance here can be, for example, the fixing portion 133 and the light-transmitting window 131 are arranged away from each other, or the fixing portion 133 and the light-transmitting window 131 are arranged at intervals or adjacently, and it should be understood that the distance here does not mean that the distance is very far, as long as the two do not meet the requirements of direct contact with each other or having an overlapping area. The fixing portion 133 is configured to be releasably connected to the belt portion 30. The fixing portion 133 may be a through hole, a blind hole, a slot, a boss, a boss, a snap ring, etc., and the fixing plate 133 may be made of a rigid or flexible material. It should be understood that the device body 100 may be directly connected to the human body through the fixing portion 133, or the projection device 100 may be connected to a wearable item having a belt portion 30 through the fixing portion 133, and then the wearable item is worn on the human body through the belt portion 30. For example, the wearable item may include a bracelet, a watch, a glove, a watch strap, a waist belt, an armband, a knee pad, a headband, a neck strap, a chest strap, clothes, socks, glasses, etc.

[0028] In some prior arts, the projection device is often integrated into the display body 40 of the wearable device 220. However, integrating the projection module and related circuits into the display body 40 requires changing the electrical and mechanical connections of the original electrical components, which has a high development cost, resulting in a larger volume and heavier weight of the display body 40, and the battery life is also affected accordingly, and it is not compatible with existing wearable devices. By setting an angle α between the optical axis direction A and the connection direction B from the first shell 10 to the second shell 30, it is ensured that the projection device 100 can be installed on the belt portion of the wearable device 220 instead of the display body 40, and when the projection device 100 is worn on the wrist 60 of the wearer, the light-transmitting window 131 can be projected to the position of the wearer 60, for example Figure 8The projection device 100 of the embodiment of the present application is shown in the palm 62 where it is located, and in other embodiments, it can also be on the back of the palm or the arm, etc., which will not affect the function and use of the original wearable device 200. Therefore, the projection device 100 of the embodiment of the present application can be compatible with the rapid combination and disassembly of various types of belt wearable devices 200, can improve the portability and compatibility of the projection device, and facilitate the flexible projection of different areas on various existing wearable devices 200, which is conducive to the efficient connection between the projection device and the existing belt wearable device, effectively improves the application scenario of the projection device, and allows the existing wearable device 200 to have an intelligent projection function. The projection device of the present application can improve the portability and compatibility of the projection device, which is conducive to the efficient connection between the projection device and the existing belt electronic products. Users can configure it on the existing belt wearable device according to their needs, which further facilitates users to watch digital information through the projection module.

[0029] In some embodiments, in conjunction with Figure 1-5 , at least one of the first wall 11 and the second wall 12 is a curved surface with an arc; for example, the first wall 11 is a curved surface, or the second wall 12 is a curved surface, or both are curved surfaces, and the second wall 12 is configured to face the side of the wearer 60, so as to facilitate adaptation to the surface of the wearer 60, such as adaptation to the wrist and other parts. The distance between the first wall 11 and the second wall 12 does not exceed 25 mm, for example, 15 mm, 18 mm, 20 mm, 25 mm, etc., which can effectively reduce the overall thickness, which is conducive to combination with existing equipment without causing the overall size to be too large.

[0030] In some embodiments, in conjunction with Figure 6-7The projection module 20 includes a micro display 21, an optical module 22, and the projection device 100 also includes a control circuit 23 and a battery 24. The optical module 22 is located at the light-emitting side of the micro display 21, and the light-emitting side of the optical module 22 is located at the light-transmitting window 131. The control circuit 23 is electrically connected to the micro display 21 and the battery 24. The projection module 20 includes a micro display 21 and an optical module 22, and the optical module 22 is located at the light-emitting side of the micro display 21. The micro display 21 can be Micro-LED (Micro Light-Emitting Diode, micro-luminescent semiconductor), uLED (micro light-emitting diode), Micro-oled (Micro Organic Light-Emitting Diode, micro-organic light-emitting diode), LCoS (Liquid Crystal On Silicon, silicon-based liquid crystal), LCD (Liquid Crystal Display, liquid crystal display), DMD (Digital Micromirror Device, digital micromirror device) / DLP (Digital Light Processing, digital light processing) or LBS (Laser Beam Scanning, laser beam scanning), etc., or any combination of these technologies. The micro display 21 can provide an image source, such as text, video, information prompts, etc. The light-transmitting window 131 is provided with an optical protective sheet 1331, which is located on the light-emitting side of the optical module 22. The projection device also includes a control circuit 23, a battery 24, and a communication unit 76 located on the first shell 10. In some embodiments, the projection device also includes a vital sign sensor 26, which is located on the second wall 12 and is configured to detect the vital signs of the wearer. The control circuit 23 and the micro display 21, the battery 24, the communication unit 76 and at least one vital sign sensor 26 are electrically connected. The vital sign sensor 26 may include a blood sugar sensor, an electromyographic sensor, a skin electrical sensor, a heart rate sensor, a pulse sensor, etc. Among them, the vital sign sensor 26 faces the wearer and is configured to detect the wearer's vital signs, for example, it is located on the wearer's wrist 60 to detect the wearer's pulse, heart rate, blood oxygen, blood pressure, etc. In other embodiments, the sensor 27 may also include an inertia sensor, a pressure sensor, a gyroscope sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, etc. The communication unit 76 may be, for example, Bluetooth, 2.4g or WiFi, etc. The battery 24 may use, for example, a lithium battery or a replaceable battery, etc. The above design enables the projection device 110 to realize the functions of communication and intelligent monitoring of vital signs, which is conducive to combination with ordinary mechanical watches, etc., so that non-smart watches can also have the functions of smart watches.It can be understood that the projection device 110 can also include an interface module 73 and an interaction module 75. The interface module 73 can be an electrical interface or a data transmission interface such as Type-C, USB, metal contacts, etc., and the interaction module 75 can be, for example, a button, voltage or capacitive touch sensor interaction to realize the command operation of the projection device 110.

[0031] In some embodiments, see Figure 1 , 4 -7, in the first direction Z, the optical module 22 and the fixing portion 133 at least partially overlap. The first direction Z may be the optical axis direction of the projection module 20, or the first direction Z may be a certain length direction of the housing (eg Figure 1 ), or the first direction Z may be, for example Figure 4 The fixing portion 133 in the example is the concave direction of the card slot (described in the following embodiments). It can be understood that the height of the optical module 22 can be higher than the height of the fixing portion 133. For example, the height of the optical module 22 can be the height direction perpendicular to the first direction Z, and the height of the fixing portion 133 can be the gap of the card slot, that is, the gap between the first contact wall 1331 and the second contact wall 1332 in the following. The height of the fixing portion 133 only needs to be clamped or surrounded to the belt portion 30 with a smaller thickness. In order to fully ensure the balance of the center of gravity distribution of the entire projection device placed on the belt portion 30, the fixing portion 133 is located in the middle or approximately the middle of the third wall 13, so the optical module 22 is also located in the middle or approximately the middle of the third wall 13 of the accommodating cavity 101, so that the optical module 22 and the fixing portion 133 at least partially overlap, which is conducive to making full use of the size of the optical module to maximize the optical efficiency and ensure that the center of gravity of the entire projection device 100 is not easy to shift.

[0032] In some embodiments, Figure 2 For example, the fixing portion 133 includes a through hole, which is located at the center of the third wall 13 and penetrates the third wall 13, so the entire belt portion 30 can penetrate the through hole, which is conducive to fixing the projection device to the belt portion 30. In some embodiments, the through hole can be located in the middle of the third wall 13, which is conducive to the balanced distribution of the center of gravity. In other embodiments, the fixing portion 133 can also include a blind hole, which is plugged into one end of a certain belt portion 30.

[0033] In some embodiments, Figure 3The fixing portion 133 includes two grooves, which are respectively arranged on both sides of the third wall 13. The two grooves can be respectively arranged at both ends of the device body 100. Exemplarily, the two grooves can be arranged on two opposite side walls, which are flush with each other, and the grooves can be formed by the third wall 13 being recessed inwardly, and the inner diameter of the groove can be greater than the width of the opening of the groove on the third wall 13. At this time, by inserting the auxiliary piece of the belt portion 30 in the groove, the projection device 100 can be worn on the belt portion 30 or different parts of the human body.

[0034] In some embodiments, see Figure 1 , 4 -6, the fixing portion 133 includes a card slot, which penetrates at least a portion of the third wall 13, wherein the card slot includes a first contact wall 1331, a second contact wall 1332 and a third contact wall 1333, wherein the first contact wall 1331 and the second contact wall 1332 are arranged opposite to each other, the first contact wall 1331 and the second wall 12 are arranged opposite to each other, the second contact wall 1332 and the first wall 11 are arranged opposite to each other, and the third contact wall 1333 is connected between the first contact wall 1331 and the second contact wall 1332. At this time, the card slot as a whole can be regarded as a U-shaped slot, and the projection device 100 can be connected to a wearable item such as a watch strap, a waist belt, socks, or clothing through the U-shaped slot, or connected to an auxiliary item of the belt portion 30 similar to a waist belt, so that the projection device 100 can be worn or different parts of the human body, such as a wrist, etc.

[0035] In some embodiments, Figure 1 The light-transmitting window 131 can be arranged on a side away from the card slot, so that the light-transmitting window 131 and the card slot of the fixing portion 133 are respectively located on different opposite sides, which can effectively reduce the interference with the light-transmitting window 131 during wearing, and is conducive to the light-transmitting window 131 to perform projection without interfering with the light-transmitting window 131, wherein the depth of the card slot in the first direction Z does not exceed three quarters of the length of the third wall 13, for example, the recessed depth of the card slot is half of the third wall, etc., which is conducive to reserving sufficient space for placing the optical module 22 for projection.

[0036] In some embodiments, in conjunction with Figure 1 , 4-6, the vital sign sensor 26 is located between the first contact wall 1331, the second wall 12 and the third wall 13, ensuring that the vital sign sensor 26 can contact the wearer. The micro display 21 and the control circuit 23 are located between the second contact wall 1332, the first wall 11 and the third wall 13. The size of this space can be larger than the space position enclosed by the first contact wall 1331, the second wall 12 and the third wall 13. At this time, the card slot of the fixing part 133 can be located in the lower middle part. The more concentrated placement of electrical components is conducive to improving assembly efficiency, reducing the risk of damage to electrical components, and facilitating subsequent maintenance. The housing 10 includes a cover plate 102 and an assembly shell 103. The assembly shell 103 is provided with a receiving cavity 101, so that the projection module, control circuit, battery and other related electrical components can be assembled to the receiving cavity 101. The cover plate 102 is covered on the assembly shell 103, and can be fixed by fasteners such as bonding, clamping or screws, for example. The cover plate 102 includes a first wall 11, and the assembly shell 103 includes a second wall 12, a third wall 13 and a fixing portion 133. The light-transmitting window 131 is provided with an optical protective sheet 1311, which can effectively prevent foreign matter from entering the receiving cavity 101 and protect the optical module 22.

[0037] Combined with reference Figure 1-9 The present application also provides a wearable device 200, including: a belt portion 30, the belt portion 30 is configured to be connected to a wearer 60, and a projection device 100 as in any of the above embodiments. The wearable device 200 may include a watch, a bracelet, a belt, etc. The wearable device 200 may be connected to a smart terminal 230 such as a mobile phone or a computer to realize data interaction, or the wearable device 200 may be directly connected to a server 220 to realize data interaction. Of course, in other embodiments, the wearable device 200 may also be indirectly connected to the server 220 through the smart terminal 230 to realize data interaction. The wearable device 220 may include a display body 40; the display body 40 may be, for example, a dial of a watch, a display screen of a bracelet, etc.; the belt portion 30 is connected to one end of the display body 40, for example, it may be connected by a rotating shaft; it can be understood that the projection device 110 is arranged on the belt portion 30, thereby realizing the wearing of the projection device 100, and the data source of the projection may come from smart terminals such as mobile phones, computers, and smart glasses, or from the display body 40 of the wearable device, that is, the content of the dial, so that elderly people with poor eyesight can also see the content on their watches. In other embodiments, the data source of the projection may also come from the server side.
