The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] As Figures 1 to 6 shown, an embodiment of the present application provides a sensor fixing device for providing a fixing basis for a sensor, and a plurality of sensor fixing devices can be expanded and assembled together to meet diverse application requirements and improve adaptability.

[0038] The sensor fixing device includes a mounting shell 100 and a clamping component.

[0039] As Figure 1 shown, the mounting shell 100 provides a mounting basis for the sensor module 600. Exemplarily, the mounting shell 100 is fixedly mounted on a fixing basis, and the fixing basis can be, for example, the ground or other fixing surfaces such as a fixing rod. For ease of understanding the technical solution of the present application, the following embodiments will describe the technical solution of the present application with a fixing rod as the fixing basis. However, it should be understood that the fixing basis is not limited to a fixing rod and may also include a fixing block, a fixing frame or a fixing surface, etc. as the fixing basis.

[0040] Exemplarily, as Figure 1 shown, the mounting shell 100 is a cuboid shell structure. As Figure 1 and Figure 3 shown, the mounting shell 100 includes at least a first side wall 110 and a second side wall 120. Exemplarily, the first side wall 110 and the second side wall 120 are two relatively arranged side walls. In another embodiment, the first side wall 110 and the second side wall 120 are joined together.

[0041] The clamping component is mounted on the side wall of the mounting shell 100. The clamping component includes a snap projection 160 and a snap groove 170. As Figure 1 and Figure 2 shown, the snap projection 160 is fixedly mounted on the first side wall 110; as Figure 3 and Figure 4 shown, the snap groove 170 is fixedly mounted on the second side wall 120, and the groove shape of the snap groove 170 is adapted to the projection shape of the snap projection 160.

[0042] During use, assuming two sensor fixing devices are provided, the two sensor fixing devices can be spliced and combined through the clamping component to fix each other.

[0043] Of course, the number of sensor fixing devices can also be three, four, or five, and there is no limit to the number. However, for the convenience of describing the technical solutions of this application, it is assumed that two sensor fixing devices are provided in the following embodiments, and the two sensor fixing devices are respectively named the first fixing device and the second fixing device. The first fixing device is fixedly installed on the fixing rod, and the buckle protrusion 160 of the second fixing device is snap-fitted into the buckle groove 170 of the first fixing device, so that the second fixing device is fixedly installed on the first fixing device to achieve extended combined installation. Or, the buckle groove 170 of the second fixing device is snap-fitted onto the buckle protrusion 160 of the first fixing device, so that the second fixing device is fixedly installed on the first fixing device to achieve extended combined installation.

[0044] As Figure 1 and Figure 2 shown, in one embodiment, the buckle protrusion 160 includes a protrusion block 200, and the protrusion block 200 is a cross-shaped block protrusion structure.

[0045] As Figure 3 and Figure 4 shown, the buckle groove 170 includes an inner groove 300, and the inner groove 300 is a cross-shaped groove structure adapted to the outer shape of the protrusion block 200.

[0046] During use, the first fixing device is fixedly arranged, and the inner groove 300 of the second fixing device is snap-fitted onto the protrusion block 200 of the first fixing device, so that the second fixing device is fixedly installed on the first fixing device. Or, the protrusion block 200 of the second fixing device is fixedly installed in the inner groove 300 of the first fixing device, so that the second fixing device is fixed to the first fixing device.

[0047] The cross-shaped design of the protrusion block 200 and the inner groove 300 provides contact points and support surfaces in multiple directions. Compared with a single-direction buckle, the cross-shaped design can provide stronger locking force and stability in multiple directions, making the connection between the two snap components more firm and not easily loosening or falling off. Due to the large and evenly distributed snap area, the risk of wear or damage caused by excessive single-point stress is reduced. At the same time, the impact force generated during the snap process is also better dispersed, protecting the overall structure of the snap components. The cross-shaped design has a certain degree of fault tolerance. Even if there is a certain positional deviation between the two snap components during docking, effective snapping can be achieved by adjusting the angle, improving the adaptability and flexibility of the mechanical structure.

[0048] In another embodiment, the technical solution in which the buckle protrusion 160 in the above embodiment includes the protrusion block 200 and the buckle groove 170 includes the inner groove 300 can also be replaced with the following technical solution:

[0049] As Figure 6As shown, the snap groove 170 includes an inner groove 300. The inner groove 300 is a blind hole or a through hole arranged in a straight line. Three inner grooves 300 are provided, and the three inner grooves 300 are distributed in a triangular pattern.

[0050] The snap projection 160 includes a projection block 200. The projection block 200 is a strip-shaped block structure arranged in a straight line. Three projection blocks 200 are provided, and the distribution mode of the three projection blocks 200 corresponds to the triangular distribution of the three inner grooves 300. Each projection block 200 can be inserted into the inner groove 300 at the corresponding position to enable the snap connection of the two sensor fixing devices.

[0051] Of course, four, five or more inner grooves 300 can be provided. The distribution mode of the inner grooves 300 can be distributed along a straight-line trajectory, a rectangular trajectory or other trajectories. Among them, four, five or more projection blocks 200 are correspondingly provided.

[0052] Such as Figure 1 and Figure 2 As shown, in one embodiment, the snap projection further includes an outer edge projection 210. The outer edge projection 210 is a raised groove wall. The outer edge projection 210 is along the outer edge of the projection block 200 and is arranged on the end face of the projection block 200 away from the mounting shell 100, so that the outer edge projection 210 forms a cross-shaped groove wall, and the outer edge projection 210 encloses to form a cross-shaped groove.

[0053] Such as Figure 3 and Figure 4 As shown, the snap groove 170 further includes a cross block 310. The cross block 310 is fixedly installed in the inner groove 300. As Figure 5 shown, there is a gap between the side wall of the cross block 310 and the inner wall of the inner groove 300, and the width of the gap matches the thickness of the outer edge projection 210.

[0054] After being installed in place, the outer edge projection 210 is snapped at the gap between the cross block 310 and the inner groove 300. The cross block 310 is snapped into the cross-shaped groove formed by the outer edge projection 210. The outer wall of the cross block 310 abuts against the inner wall of the outer edge projection 210, and the inner wall of the inner groove 300 abuts against the outer wall of the outer edge projection 210, increasing the snap contact area and improving the snap strength.

[0055] The presence of the outer edge protrusion 210 and the cross-shaped block 310 increases the contact area of the clamping part, thereby improving the connection strength and stability. Especially when the thickness of the outer edge protrusion 210 matches the width of the gap, it can ensure a tight fit between the two, preventing connection failure caused by loosening or vibration. By increasing the clamping contact area and reducing the single-point force, the pressure and impact force at the connection part can be dispersed, thereby reducing wear and extending the service life. At the same time, the tight clamping relationship also helps to prevent connection failure caused by loosening or vibration.

[0056] As Figure 1 shown, in one embodiment, the protrusion block 200 includes a first protrusion part 202 and a second protrusion part 204. The first protrusion part 202 and the second protrusion part 204 are cross-fixed and connected with a first preset angle α, where 0° ≤ α ≤ 90°.

[0057] As Figure 3 shown, the inner groove 300 includes a first groove body 302 and a second groove body 304. The first groove body 302 and the second groove body 304 are communicated and have a first preset angle α, where 0° ≤ α ≤ 90°.

[0058] Exemplarily, α = 10°. In another embodiment, α = 30°. In another embodiment, α = 45°. In yet another embodiment, α = 90°. In one embodiment, α = 0°, that is, the first protrusion part 202 and the second protrusion part 204 are arranged as a whole to form a convex block, and the first groove body 302 and the second groove body 304 are arranged as a whole to form a groove body.

[0059] As Figure 2 and Figure 4 shown, in one embodiment, the mounting shell 100 further includes a third side wall 130.

[0060] As Figure 2 and Figure 4 shown, the sensor fixing device further includes a fixing component for fixedly installing the mounting shell 100 on a fixing base, such as a fixing rod.

[0061] The fixing component includes a fixing protrusion 400 and a connection terminal 410. The fixing protrusion 400 is fixed on the third side wall 130 of the mounting shell 100; a fixing groove is correspondingly provided on the fixing rod, and the shape of the fixing groove is adapted to the shape of the fixing protrusion 400. The fixing protrusion 400 is clamped in the fixing groove to fix the mounting shell 100 on the fixing rod.

[0062] The connection terminal 410 is fixedly arranged on the fixing protrusion 400, and the sensor module 600 is electrically connected to an external device through the connection terminal 410.

[0063] The fixed rod is provided with interface terminals electrically connected to the connection terminals 410. External devices such as intelligent mobile terminals and / or power sources can be electrically connected to the connection terminals 410 through the interface terminals, and can be electrically connected to the sensor module 600 through the interface terminals and the connection terminals 410, and supply electrical energy to the sensor module 600 through the interface terminals and the connection terminals 410.

[0064] Through the snap - fit design of the fixing protrusions 400 and the fixing grooves, the mounting shell 100 can be firmly fixed on the fixed rod. This design not only simplifies the installation process but also improves the stability and reliability of the installation. The matching degree of the fixing protrusions 400 and the fixing grooves ensures that the sensor module 600 is not prone to shaking or falling off during operation, guaranteeing the accuracy of measurement and the stability during long - term use.

[0065] The connection terminals 410 are arranged on the fixing protrusions 400, making the electrical connection between the sensor module 600 and external devices simple and direct, simplifying the electrical connection process, enabling external devices such as intelligent mobile terminals and / or power sources to be easily connected, providing electrical energy and data transmission for the sensor module 600, making the sensor fixing device applicable to different types of fixing bases and external devices, and improving the versatility and expandability of the device. Different sensor modules 600 can be installed at different positions through the same fixing device, and external devices can also be easily connected through standardized interface terminals, thus meeting diverse application requirements.

[0066] Such as Figure 2 and Figure 4 shown, in one embodiment, the fixing component further includes a fixing frame 420. The fixing frame 420 is fixedly installed on the outer side of the fixing protrusions 400, and the outer side of the fixing protrusions 400 is the side away from the mounting shell 100. Setting the fixing frame 420 can increase the snap - fit area between the fixing component and the fixed rod, improve the strength of the snap - fit connection, and enhance the snap - fit stability and reliability. During the snap - fit process, the fixing protrusions 400 may be subjected to extrusion pressure and friction force from the fixing grooves. The presence of the fixing frame 420 can help disperse these stresses, reduce damage to the fixing protrusions 400 themselves, and thus extend their service life. The fixing frame 420 can also prevent the fixing protrusions 400 and the connection terminals 410 from being damaged by accidental collisions during transportation, installation, or use. The fixing frame 420 protects the fixing protrusions 400 and the connection terminals 410 inside the fixing frame 420, reducing the impact of external shocks on them.

[0067] Such as Figure 2 and Figure 4 shown, in one embodiment, the fixing protrusions 400 are triangular block structures, and the fixing frame 420 is a triangular frame structure.

[0068] The fixing protrusion 400 adopts a triangular frame structure, which can more effectively resist forces from all directions and ensure the stable position of the installation shell 100 on the fixing rod.

[0069] The fixing frame 420 serves as the peripheral support of the fixing protrusion 400 and adopts a triangular frame structure, further enhancing the overall stability. The multiple support points of the triangular frame make the structure more stable and less likely to deform or loosen. The triangular frame structure of the fixing protrusion 400 is relatively compact, which can reduce the space occupation while ensuring the strength, making the sensor fixing device more compact, lightweight, and convenient for installation and carrying.

[0070] As Figure 2 and Figure 4 shown, in one embodiment, the connection terminal 410 includes multiple sub-connection terminals. Among them, at least two sub-connection terminals are used to connect the sensor module 600 to the power supply, and at least one sub-connection terminal is used to enable the sensor module 600 to communicate with external devices.

In another embodiment, three sub-connection terminals are provided. Two sub-connection terminals are used to supply electrical energy to the sensor module 600, and the other one sub-connection terminal is used for communication connection with external devices, such as establishing single-ended communication transmission with external devices.
