They are also equipped with projection indicator lights to help users determine the location of the laser sensor and advertising. However, most of them currently use an integrated, non-removable design for the laser sensor and projection light, which makes it impossible to freely combine laser sensing and projection functions. Furthermore, if a single functional component is damaged, the entire module needs to be replaced, resulting in high maintenance costs. Utility Model Content

The laser ranging plate and the light-blocking sleeve each have through holes penetrating their inner and outer surfaces, and the through holes of the laser ranging plate and the light-blocking sleeve correspond to each other. The sleeve passes through the through holes of the laser ranging plate and the light-blocking sleeve. The laser ranging plate is disposed inside the light-blocking sleeve, and the through hole of the light-blocking sleeve is fitted onto the outer peripheral surface of the mounting channel. The light-blocking sleeve is located between the housing and the laser ranging plate.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0025] Example 1
[0026] Reference Figures 1 to 4 Embodiment 1 provides a laser sensing module with projection capabilities (hereinafter referred to as laser sensing module 100) to meet the user's single need for laser sensing function or the combined need for both laser sensing and projection functions. Therefore, users can freely combine them according to the needs of different application scenarios. For example, in hotel scenarios, laser sensing is used and logo patterns or marks are projected in the laser sensing area; in exhibition or store promotion scenarios, laser sensing is used and logo patterns are projected in the laser sensing area; in home scenarios, only laser sensing function is used. The laser sensing module 100 of this embodiment can significantly shorten the response cycle to achieve flexible adaptation.
[0027] like Figure 1 and Figure 2 As shown, the laser sensing module 100 of this embodiment includes a laser sensing component 1 for laser ranging and a projection component 2 for projecting indicator icons 23.
[0028] The laser sensing component 1 includes a housing 11 that is transparent to laser (e.g., infrared) and a laser ranging unit 12 mounted on the housing 11. The projection component 2 includes a sleeve 21 and a projection unit 22 mounted on the sleeve 21, and the laser ranging unit 12 is electrically connected to the projection unit 22.
[0029] The housing 11 is provided with an installation channel 111 for the sleeve 21. The sleeve 21 passes through the laser ranging unit 12 and is detachably assembled into the installation channel 111.
[0030] In this embodiment, as Figure 2 and Figure 3 As shown, the circumferential wall of the installation channel 111 is provided with a buckle 112 that protrudes outward, and the circumferential wall outside the sleeve 21 is provided with a groove 211 that matches the buckle 112.
[0031] When the sleeve 21 is inserted into the mounting channel 111, the buckle 112 can be detachably engaged with the slot 211 to form a detachable connection between the laser sensing component 1 and the projection component 2. At this time, the outward opening of the mounting channel 111 is the light outlet 24 of the projection unit 22.
[0032] More specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the laser ranging unit 12 includes a laser ranging plate 121 and a light-blocking sleeve 122. The laser ranging plate 121 and the light-blocking sleeve 122 each have through holes penetrating their inner and outer surfaces, and the through holes of the laser ranging plate 121 and the light-blocking sleeve 122 correspond to each other so that the installation channel 111 passes through the through holes of the laser ranging plate 121 and the light-blocking sleeve 122 to form a sleeve structure. Specifically, the laser ranging plate 121 has a laser ranging chip 123 for laser ranging or sensing functions. The light-blocking sleeve 122 is provided with light-emitting holes 124 and light-receiving holes 125 spaced apart from each other. The light-emitting end of the laser ranging chip 123 corresponds to the light-emitting hole 124, and the light-receiving end of the laser ranging chip 123 corresponds to the light-receiving hole 125. In this way, the light emission and light reception of the laser ranging chip 123 are isolated from each other, thereby preventing crosstalk between transmission and reception. Of course, the laser rangefinder board 121 is also equipped with an external wiring 32 for electrical connection with external devices, so as to power the entire module and communicate with external devices.
[0033] When the laser sensing component 1 is assembled, the laser rangefinder plate 121 is placed inside the light-blocking sleeve 122, and the through hole of the light-blocking sleeve 122 is fitted onto the outer peripheral surface of the installation channel 111. At this time, both the laser rangefinder plate 121 and the light-blocking sleeve 122 are located inside the housing 11, and the light-blocking sleeve 122 is located between the housing 11 and the laser rangefinder plate 121.
[0034] When an object is detected entering within the sensing range of the laser sensing component 1, a sensing signal can be generated to trigger other devices (such as the opening or flushing action of a smart toilet).
[0035] Also, such as Figure 2 and Figure 3 As shown, the projection assembly 2 includes a lens 221 for collimating the projection light, a miniature projection sheet 222 for providing an indicator icon 23, and a lamp board 223 for providing a projection light source. The lens 221, the miniature projection sheet 222, and the lamp board 223 are respectively disposed within the sleeve 21, with the miniature projection sheet 222 located between the lens 221 and the lamp board 223. The lens 221 is an independent optical device and is installed within the sleeve 21, located below the miniature projection sheet 222. The lamp board 223 is located above the miniature projection sheet 222, away from the lens 221. The laser rangefinder plate 121 is electrically connected to the lamp board 223 via a waterproof connecting cable 33 and a detachable waterproof connector 34 to control the light source of the lamp board 223 to turn on and off, and to adjust the brightness and color of the light source. Of course, the material of the light board 223 can be any circuit board material, such as an aluminum substrate; and the light source can also be an LD lamp (i.e., a laser diode lamp), an LED lamp, or an RGB LED, etc.; in addition, the miniature projection sheet 222 can store indicator patterns or marks, such as brand trademarks or logo patterns, etc.
[0036] When the laser rangefinder plate 121 powers the light board 223, the light source of the light board 223 lights up. The light emitted by the light source passes through the miniature projection sheet 222, and then is collimated by the lens 221 before being emitted outward through the opening (i.e., the light outlet 24) of the mounting channel 111, so as to project the indicator mark or pattern on the miniature projection sheet 222 to the desired external position (which is also the laser sensing area), such as projecting indicator marks or brand promotion or display patterns within the laser sensing area.
[0037] The laser sensing component 1 can realize the distance measurement (sensing) function, and the projection component 2 can realize the projection of indicator marks in the laser sensing area. It can be flexibly selected according to different user needs. That is, the laser sensing module 100 in this embodiment can be equipped with the projection component 2 or not, based on the laser sensing component 1. In addition, the projection component 2 can also be selected according to the corresponding projection pattern or mark.
[0038] In summary, the detachable connection between the laser sensing component 1 and the projection component 2 allows the projection component 2 to be used separately from the laser sensing component 1, thereby meeting the user's single need for laser sensing function or the combined need for both laser sensing and projection functions. Furthermore, if only the projection component 2 is damaged, only the projection component 2 needs to be replaced, thus reducing maintenance costs.
[0039] Of course, in other embodiments, the positions of the buckle 112 and the slot 211 can be interchanged, which will not be described in detail here.
[0040] Alternatively, the lens 221 can be integrated with the sleeve 21 to achieve lower manufacturing and assembly costs.
[0041] Furthermore, the housing 11 and the sleeve 21 can also be connected by a snap-fit structure, a threaded connection structure, or a magnetic connection structure; the sleeve 21 can also be located in any area within the housing 11, and does not need to be located in its center; or the outer wall of the housing 11 is connected to an installation channel 111, and the sleeve 21 is detachably installed in the installation channel 111 and arranged side by side with the housing 11, that is, the projection component 2 is located outside the laser sensing component 1.
[0042] In another preferred embodiment, such as Figure 2 As shown, the circumferential wall of the mounting channel 111 is provided with a plurality of slots 113 extending to the upper end face of the sleeve 21. The slots 113 are square grooves with openings on one side. The slots 113 are arranged at intervals around the center of the mounting channel 111 to divide the circumferential wall of the mounting channel 111 into a plurality of elastic snap-fit blocks 114. The snap-fit blocks 114 are provided with buckles 112, so that the buckles 112 can be smoothly separated from or snapped into the slots 211 under the elastic force of the snap-fit blocks 114.
[0043] More preferably, when the laser sensing component 1 is assembled, the outer peripheral surface of the light-blocking sleeve 122 and the inner peripheral surface of the housing 11 form an interference fit to prevent glue from leaking into the housing 11 during potting.
[0044] Example 2
[0045] like Figure 5 and Figure 6 As shown, Embodiment 2 provides a smart toilet, including a toilet body 200, a main control system, and the laser sensing module 100 of Embodiment 1.
[0046] The laser sensing module 100 is assembled onto the toilet body 200 via the adapter plate 31, and the laser sensing component 1 of the laser sensing module 100 triggers the toilet body 200 to open the lid or flush via the main control system.
[0047] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
