[0017] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0018] The embodiment of the present application provides a projection device 1, the specific structure of which is shown in Figures 1-8. The projection device 1 includes a base 13, a support frame 12, and a projector body 11 connected in sequence. The projector body 11 includes a housing assembly 111. The outer surface of the housing assembly 111 is provided with a receiving groove 1111 for accommodating and adapting the support frame 12. The support frame 12 and the projector body 11 are rotatably connected within the receiving groove 1111.

[0019] The pivoting connection between the support frame 12 and the projector body 11 enables adjustment of the projection angle of the projector body 11. The storage slot 1111 defined on the outer surface of the housing assembly 111 fully accommodates the support frame 12, further reducing the space occupied by the projector device 1 when stored. The overall storage structure is simple and effective. The pivoting connection between the support frame 12 and the projector body 11 within the storage slot 1111 not only allows the storage slot 1111 to accommodate the support frame 12, but also allows the internal structure of the storage slot 1111 to be concealed, resulting in a more aesthetically pleasing overall appearance.

[0020] In some embodiments, the support frame 12 and the base 13 are integrally connected or detachably connected.

[0021] Optionally, the support frame 12 and the base 13 are integrally formed into an integrated structure, and the overall structure has good mechanical properties and is easy to use.

[0022] Optionally, the support frame 12 and the base 13 are detachably connected. In special occasions, the support frame 12 and the projector body 11 can be used as a whole in conjunction with other structures, thereby making the projection device 1 more applicable to various scenarios and having a wider range of applications.

[0023] Specifically, in the specific embodiment of the present application, at least a portion of one end of the support frame 12 is integrally connected to the base 13 to increase the stability of the connection.

[0024] More specifically, the support frame 12 is disposed on the outer periphery of the base 13 .

[0025] In some embodiments, the rotation angle between the projector body 11 and the support frame 12 is 0°-180°.

[0026] Specifically, when the angle between the projector body 11 and the support frame 12 is 0-15°, the projector body 11 is in the storage state.

[0027] When the included angle between the projector body 11 and the support frame 12 is 15°-180°, the projector body 11 is in an unfolded state.

[0028] Optionally, when the angle between the projector body 11 and the support frame 12 is 90°-180°, in order to prevent the shell assembly 111 from blocking the rotation of the support frame 12, the storage groove 1111 is a through groove structure that penetrates the shell assembly 111 and connects the two end surfaces.

[0029] In the specific embodiment of the present application, the angle between the projector body 11 and the support frame 12 is 0°-90°, that is, the storage groove 1111 is only opened at one end of the outer surface of the shell assembly 111. There is no restriction on the specific opening form of the storage groove 1111, which is subject to the actual product.

[0030] When the included angle between the projector body 11 and the support frame 12 is 90° (as shown in FIG. 2 ), that is, when the axial extension directions of the projector body 11 and the support frame 12 are perpendicular to each other, it is a commonly used projection angle.

[0031] In some embodiments, as shown in Figures 2 and 4 to 6, the support frame 12 includes a rotating portion 122 rotatably connected to the inner wall of the housing assembly 111, and a connecting portion 121 fixedly connected to the rotating portion 122. Two through holes 1114 are provided on the side wall of the storage groove 1111 at positions corresponding to the rotating portion 122, and both ends of the rotating portion 122 penetrate into the housing assembly 111 through the through holes 1114. Rotating the rotating portion 122 realizes multi-level adjustment rotation feedback of the projector body 11 and the support frame 12 within the rotation range. When the rotating portion 122 rotates relative to the projector body 11, the housing assembly 111 and the projector body 11 move synchronously to adjust the projection angle of the projector body 11. The multi-level rotation achieved by the cooperation of the rotating portion 122 and the housing assembly 111 can adjust the projector body 11 to any angle and keep it fixed, which is more convenient to use.

[0032] In some embodiments, the rotating portion 122 is limited on the inner wall of the shell assembly 111 by a limiting member 1115, and an axial hole 1118 (Figure 6) adapted to the rotating portion 122 is formed between the limiting member 1115 and the wall of the shell assembly 111. The rotating portion 122 cooperates with the shell assembly 111 through the axial hole 1118 to achieve limitation and rotation.

[0033] Specifically, in the specific embodiment of the present application, the rotating part 122 includes a smooth section 1221 and a gear section 1222 arranged at at least one end of the smooth section 1221, the smooth section 1221 is adapted to the shaft hole 1118, and the smooth section 1221 and the gear section 1222 are coaxially arranged and move coaxially and synchronously.

[0034] The housing assembly 111 includes a limiter 1115 disposed therein and abutting against the two gear segments 1222 . When the rotating portion 122 rotates in the shaft hole 1118 , the gear segments 1222 abut or clamp the limiter 1115 to drive the projector body 11 to rotate along with the rotating portion 122 .

[0035] In some embodiments, as shown in conjunction with Figures 5 and 8 , the stopper 1115 is provided with an elastic member 1116 that meshes with the gear segment 1222. The elastic member 1116 abuts against the gear segment 1222 and deforms when the elastic member 1116 and the gear segment 1222 move relative to each other. Specifically, there are two gear segments 1222, one located at each end of the smooth segment 1221, and the elastic member 1116 corresponds one to one with the gear segment 1222. The elastic member 1116 is provided with a positioning tooth 1117 that fits into the tooth gap of the gear segment 1222. When the rotating portion 122 rotates relative to the stopper 1115, the gear segment 1222 abuts against the positioning tooth 1117, causing the positioning tooth 1117 to deform from one tooth gap to the next. When the gear segment 1222 rotates, the positioning teeth 1117 of the elastic member 1116 engage with the gear segment 1222. As the gear segment 1222 rotates, the elastic member 1116 deforms periodically and produces sound, thereby realizing multi-level adjustable rotation feedback.

[0036] When the projector body 11 rotates relative to the support frame 12, the elastic member 1116 of the limit member 1115 is deformed, and the positioning tooth 1117 and the gear segment 1222 slide relative to each other, thereby realizing the step-by-step rotation between the projector body 11 and the support frame 12. When the projector body 11 stops rotating, the positioning tooth 1117 and the gear segment 1222 remain engaged and fixed in the corresponding positions, so that the relative angle of the projector body 11 at this time is maintained.

[0037] In some embodiments, the support frame 12 is a retractable support frame, the retractable end of the support frame 12 is integrally connected to the connecting portion 121 , and the other end is disposed on the base 13 . The support frame 12 can be stored in the storage slot 1111 after being fully retracted.

[0038] Specifically, the support frame 12 includes a retractable multi-section telescopic rod. When two adjacent telescopic rods are fully extended, they are relatively fixed, so that the multi-section telescopic rods can bear the weight of the projector body 11 without retracting in the stretched state.

[0039] More specifically, when the telescopic rod is fully retracted and stored in the storage groove 1111, the outer surface of the telescopic rod is in the same plane as the shell assembly 111, or the outer surface of the telescopic rod is concave relative to the outer surface of the shell assembly 111, so that the telescopic rod is protected after being stored by the shell assembly 111.

[0040] The retractable design of the support frame 12 can accommodate a longer length with minimal space occupation to meet the user's projection needs. The storage slot 1111 can accommodate the fully retracted support frame 12, further saving space and making the projection device 1 more convenient to carry and store.

[0041] In some embodiments, please refer to Figures 1 and 3 , the projector body 11 includes a broadcasting component 112 arranged in a shell component 111, a sound outlet hole 1112 connected to the interior is opened on the shell component 111, a dust cover 1113 is provided at the sound outlet hole 1112, and the broadcasting component 112 emits sound to the outside through the sound outlet hole 1112 and the dust cover 1113.

[0042] Sound hole 1112 connects the inside and outside of housing assembly 111 to the outside for external sound output. Dust cover 1113 protects sound hole 1112 and the internal structure without affecting sound quality, preventing mechanical collisions and intercepting impurities. Sound hole 1112 connects the inside and outside of housing assembly 111 to the outside for external sound output. When in use, projector body 11 plays sound in a directionally directed manner through sound hole 1112, thereby ensuring the sound quality of projection device 1 and enhancing the viewing experience for the user.

[0043] Specifically, the sound outlet holes 1112 are symmetrically opened on the housing assembly 111 , and the covering area of ​​the dust cover 1113 is greater than or equal to the area of ​​the sound outlet holes 1112 .

[0044] In some embodiments, as shown in FIG3 , the projector body 11 further includes a projection assembly 113 disposed within the housing assembly 111 . The projection assembly 113 includes a projection lens 1131 . The projection lens 1131 is disposed in the axial extension direction of the projector body 11 . When the projection device 1 is fully stored, the projection lens 1131 or the end face away from the projection lens 1131 faces the base 13 . The projection lens 1131 being disposed on the end face allows for intuitively obtaining the projection direction by adjusting the pitch angle of the projector body 11 , making adjustment easier. By storing the projection lens 1131 or an end face away from the projection lens 1131 so as to face the base 13 , the base 13 and the housing assembly 11 are utilized to protect the components or devices on the end face, thereby further saving space. While simplifying storage and carrying, the protection of the components of the projection device is enhanced, thereby increasing its service life.

[0045] Specifically, the end where the projection lens 1131 is located is the projection end, and the end of the projection component 113 away from the projection lens 1131 is the operation end, which can realize the control of the projection device 1, charging, connection to external devices and heat dissipation functions.

[0046] It should be noted that in the specific embodiment of the present application, the support frame 12 is arranged on the periphery of the base 13. When the projection device 1 is folded and stored, one of the projection end or the operating end is aligned with the middle area of ​​the base 13, so that the base 13 can protect the components at that end.

[0047] When the projection device 1 is stored, either the projection end or the operating end can be directly opposite the base 13 to protect the components on that end. There is no limitation here and it is subject to actual needs. In the specific embodiment of the present application, after the projection device 1 is stored, the operating end is directly opposite the base 13 to improve the protection of the operating end.

[0048] It can be understood that the projection lens 1131 is arranged on the end surface, and when in use, the pitch angle of the projector body 11 can be adjusted to a suitable projection direction, and the adjustment is relatively simple.

[0049] By storing the projection lens 1131 or an end face away from the lens to face the base 13, the base 13 and the shell assembly 111 are used to protect the components or devices on the end face, while further saving space, making it easy to store and carry, while enhancing the protection of the components of the multi-projection device 1 and increasing its service life.

[0050] In some embodiments, when the projection device 1 is fully retracted, the distance between the projection end or operating end and the base 13 is 2-10 mm. By limiting the distance between the projection lens in the projector body 11 or the end away from the projection lens and the base, the base 13 can limit the rotational freedom of the projector body 11 in the retracted state, thereby preventing the projector body 11, support frame 12, and base 13 from accidentally unfolding in the retracted state, thereby protecting the projector body 11 and reducing the possibility of damage to the device due to collision.

[0051] Optionally, the distance between the projection end or the operating end and the base 13 may be 2 mm, 5 mm, 7 mm or 10 mm.

[0052] Specifically, in the specific embodiment of the present application, the distance between the projection end or the operating end and the base 13 is 3 mm.

[0053] In addition, in order to prevent the projection end or the operating end from colliding with the base 13 during the storage process and causing damage to the projection device 1 itself, when storing, it is necessary to first maintain the telescopic rod at a certain height and then rotate the projector body 11 toward the support frame 12, and finally lower the projector body 11 to the lowest point to complete the storage.

[0054] It can be understood that by limiting the distance between the projection lens 1131 in the projector body 11 or the end face away from the projection lens 1131 and the base 13, the base 13 can limit the rotational freedom of the projector body 11 around the support frame 12 in the fully stored state, thereby preventing the projector body 11 from expanding relative to the support frame 12 and the base 13 due to external force when in the stored state, thereby improving the protection of the projector body 11 and reducing the possibility of damage to the equipment due to collision.

[0055] Furthermore, referring to FIG. 7 , a fixing member 131 for fixing the base 13 is provided on a side of the base 13 away from the support frame 12 .

[0056] It should be noted that the fixing member 131 is disposed between the base 13 and the supporting surface. Therefore, the type, thickness, and location of the fixing member 131 will affect the horizontality of the projection device 1 .

[0057] Specifically, in the specific embodiment of the present application, the fixing member 131 is a symmetrically arranged anti-slip pad with the same height.

[0058] It can be understood that the fixing member 131 is used to make the connection between the base 13 and the supporting surface more secure, preventing slipping while ensuring the safety of the projection device 1 during use.

[0059] Specifically, referring to Figures 1, 2, and 4, after using the projection device 1, the projector body 11 must first be rotated so that the angle between the projector body 11 and the support frame 12 is 0-15°, and then the support rods in the support frame 12 must be retracted until the support frame 12 is retracted to its shortest state and stored in the storage slot 1111. At this time, the projector body 11 is facing the middle of the base 13, completing the storage process. The retractable design of the support frame 12 can accommodate a longer length with minimal space occupation, meeting the user's projection needs. The storage slot 1111 can accommodate the fully retracted support frame 12, further saving space and making it more convenient to carry and store the projection device.

[0060] Specifically, when the projection device 1 is in the stored state and needs to be unfolded for use, the base 13 is placed on the platform, the projector body 11 can be raised first, and the telescopic rod in the support frame 12 can be pulled out to move the projector body 11 away from the base 13. After the telescopic rod is stretched to a certain distance, it is ensured that the end face of the projector body 11 will not touch the base 13 during rotation, and the projector body 11 is rotated to a suitable angle to realize the unfolding and use process of the projection device 1.

[0061] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the principles of the present application should be included in the scope of protection of the present application.
