Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown, this utility model proposes a multimodal spatial sensing module, including a housing 100, a control module 200, a sensing module 300, a cover 400, and a waterproof component 500. The housing 100 is provided with a first window 101 that connects to the interior of the housing 100. The control module 200 is built into the housing 100. The sensing module 300 is built into the housing 100 and electrically connected to the control module 200. The sensing module 300 is used to perform multimodal spatial sensing to the outside world. The cover 400 is detachably installed on the housing 100 to cover the first window 101. The waterproof component 500 is disposed between the cover 400 and the housing 100.

[0027] It should be noted that the housing 100 adopts a relatively closed, small-volume box-like structure, the shape of which includes but is not limited to square, round, polygonal, etc. The control module 200 and the sensing module 300 are compactly integrated into the housing 100 to reflect the miniaturized design and facilitate adaptation to any smart device to assist in sensing. The first window 101 is specifically the opening side of the housing 100. The control module 200 and the sensing module 300 can be installed into the housing 100 through the first window 101. The cover 400 is a plate structure and its shape is adapted to the first window 101 to cover the first window 101. The waterproof component 500 is set between the cover 400 and the housing 100 to fill the gap between the cover 400 and the housing 100, effectively preventing external dust, water stains, etc. from entering the housing 100, thereby improving the waterproofness and safety of the multimodal spatial sensing module.

[0028] It should be added that the shell 100 structure can be assembled from multiple plates or it can be an integrated structure. In this embodiment, an integrated shell 100 structure is preferred to avoid too many seams and further improve the waterproofness and safety of the multimodal spatial sensing module.

[0029] The cover 400 can be detachably installed using various connection methods such as fastener connection, screw assembly, bayonet engagement, and key connection. In this embodiment, screw assembly is preferred because it is cost-effective and has a quick-release and quick-installation structure. Since the multimodal spatial sensing module needs to have excellent waterproof performance, fixing the cover 400 to the housing 100 with screws can ensure the stability of the cover 400 on the housing 100 for a long time.

[0030] The specific application of the sensing module 300 is to perform multimodal spatial perception of the outside world or external targets. Here, multimodal means using a variety of different forms or sensing channels to exchange information. In other words, the sensing module 300 can use a variety of different sensing methods (i.e., it uses a variety of sensors and other sensing devices) to capture the spatial morphology and structure of the outside world or external targets.

[0031] In one embodiment of this application, an annular groove 102 is provided around the first window 101, and a waterproof component 500 is disposed in the annular groove 102. When the cover 400 covers the first window 101, the cover 400 also covers the annular groove 102 and abuts against the waterproof component 500.

[0032] In one embodiment of this application, the waterproof component 500 includes a waterproof rubber ring whose shape is adapted to the annular groove 102.

[0033] It should be noted that, since the cover 400 and the housing 100 need to maintain a fixed fit for a relatively long time, screw assembly is adopted. While providing a good fixing effect, the waterproof component 500 can also be made of waterproof adhesive, which is applied between the cover 400 and the housing 100 by injection, achieving a good waterproof effect. However, in this embodiment, screw assembly is chosen because it still retains the function of being detachable, so as to facilitate subsequent disassembly, replacement and maintenance. Therefore, the waterproof component 500 is preferably a waterproof rubber ring that fits into the annular groove 102. This waterproof rubber ring has good elasticity. When the cover 400 is connected to the housing 100, the waterproof rubber ring is compressed, increasing the contact area with the cover 400 and the housing 100, thereby filling the joint between the cover 400 and the housing 100. When the cover 400 is removed from the housing 100, the waterproof rubber ring rebounds, which will not affect the disassembly of the cover 400.

[0034] In one embodiment of this application, the multimodal spatial sensing module further includes a frame 600 built into the housing 100, and the control module 200 and the sensing module 300 are respectively fixed on the frame 600.

[0035] The housing 100 is also provided with a second window 103 and a transparent plate 104. The transparent plate 104 is used to cover the second window 103. The sensing end of the sensing module 300 faces the second window 103 and senses the outside world through the transparent plate 104.

[0036] The sensing module 300 includes a visual sensing unit 301, a laser TX unit 302, and a laser RX unit 303. The visual sensing unit 301 is used to acquire visual image data from the outside world, the laser TX unit 302 is used to emit laser light to the outside world, and the laser RX unit 303 is used to receive laser light reflected from the outside world.

[0037] It should be noted that the frame 600 is actually composed of a simple frame and brass pillars. The sensing module 300 also includes three electrically connected circuit boards. One circuit board is installed in the frame, and the other two circuit boards serve as side plates, respectively installed on both sides of the frame, to achieve a compact structural design and reduce the size of the multimodal spatial sensing module. These three circuit boards are electrically connected to the visual sensing unit 301, the laser TX unit 302, and the laser RX unit 303, respectively. One circuit board serves as the main control board, integrating and processing the information sensed and acquired by the visual sensing unit 301, the laser TX unit 302, and the laser RX unit 303. MindSLAM is built into this board. TMThe high-performance navigation and mapping algorithm, in conjunction with the visual perception unit 301, the laser TX unit 302, and the laser RX unit 303, constructs a high-precision spatial environment perception system and a spatial memory system similar to the "hippocampus" of the brain. Even in extreme environments such as no light, no features, and high light transmittance, it still has highly robust positioning and mapping capabilities.

[0038] In one embodiment of this application, the multimodal spatial sensing module further includes a socket 201 and a USB interface 202 that are electrically connected to the control module 200, respectively.

[0039] It should be noted that the socket 201 and the USB interface 202 are electrically connected to the circuit board mentioned above as the main control board. The socket 201 includes a four-pin aviation socket, which includes four pins for power positive and negative, general bidirectional I / O, and bidirectional synchronous signal transmission, respectively. The USB interface 202 includes a USB-C 3.0.

[0040] In one embodiment of this application, both the housing 100 and the cover 400 are made of materials with high thermal conductivity.

[0041] It should be noted that, due to the relatively compact structure and small volume of the entire structure, there is no active heat dissipation device in the internal structure. Therefore, in this embodiment, the housing 100 and the cover 400 are used as passive heat dissipation structures. They are made of materials with high thermal conductivity, so that the heat generated by the components inside the housing 100 can be quickly conducted to the outside by the housing 100 and the cover 400 and exchanged with the outside, thereby achieving the heat dissipation effect.

[0042] In one embodiment of this application, in order to improve the passive heat dissipation effect, the housing 100 and the cover 400 are provided with a plurality of heat dissipation grooves 700 to increase the surface area of ​​the housing 100 and the cover 400 to exchange heat with the outside, thereby improving the heat dissipation efficiency.

[0043] In one embodiment of this application, the cover 400 is provided with a plurality of reserved holes 800.

[0044] It should be noted that the effectiveness of passive heat dissipation always depends on the thermal conductivity of the material and the ambient temperature difference. The material can be selected according to the requirements, but the ambient temperature difference is difficult to control. If the temperature inside the multimodal spatial sensing module is not much different from the outside temperature, its heat dissipation effect is extremely poor. Therefore, multiple reserved holes 800 are provided on the cover 400. These multiple reserved holes 800 are used as fixing positions for active heat sinks such as cooling fans. Users can add corresponding active heat sinks according to their needs to improve the heat dissipation effect of the multimodal spatial sensing module.

[0045] It should be noted that the above descriptions are one or more embodiments provided in conjunction with specific content, and do not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
