When the compartment cover 9 slides on the pressing plate 8 from the free end 81 to the fixed end 82, the compartment cover 9 is locked and limited at the compartment door 7 to achieve sealing of the compartment door 7 When the lid is closed and the bin cover 9 is locked and limited at the bin door 7, the bin cover 9 and the shell body are tightly connected and flush to cover and hide the rotating shaft and the pressure plate 8, making the overall appearance of the shell cover mechanism more beautiful. When the bin cover 9 slides out from the fixed end 82 to the free end 81 on the pressure plate 8, the bin cover 9 and the bin door 7 are released from the limit cooperation to open the bin door 7, that is, a certain distance can be opened between the bin cover 9 and the edge of the bin door 7, thereby increasing the range of movement of the bin cover 9 for rotation and opening, so that the opening angle of the bin cover assembly can be greater than 90°, thereby increasing the opening angle of the bin cover assembly; and the replacement process of the battery 15 is also relatively simple and quick, thereby improving the replacement efficiency.

[0032] In this embodiment, the bin cover 9 is arranged on the outer side of the pressure plate 8 for sliding left and right. The upper end of the inner side of the bin cover 9 is provided with a first upper buckle 91 with a bayonet facing downward, and the lower end is provided with a first lower buckle 92 with an upward bayonet. The upper and lower sides of the pressure plate 8 are respectively provided with a clearance notch 83 for the first upper buckle 91 or the second upper buckle 93 to assemble and make way. The first upper buckle 91 and the first lower buckle 92 cooperate with each other to limit the upper and lower front and back directions of the pressure plate 8, that is, the first upper buckle 91 and the first lower buckle 92 respectively move forward through the clearance notches 83 on the upper and lower sides of the pressure plate 8 and then slide to the left. The setting of the clearance notch 83 makes it more convenient and quick to install the bin cover 9 on the outer side of the pressure plate 8, so that the bin cover 9 does not need to be slid into the plate body from the free end 81. Among them, there are two pairs of clearance gaps 83, and one pair of first upper buckles 91 and first lower buckles 92, which ensure the stability of the compartment cover 9 in limiting the upper and lower front and back directions of the pressure plate 8, and improve the assembly stability between the compartment cover 9 and the pressure plate 8.

[0033] In this embodiment, the upper end of the inner side of the bin cover 9 is provided with a second upper buckle 93 with the bayonet facing upward, and the lower end is provided with a second lower buckle 94 with the bayonet facing downward. The upper and lower sides of the bin door 7 are respectively provided with slots, and the second upper buckle 93 and the second lower buckle 94 are respectively matched with the corresponding limit positions of the slots to realize the closing of the bin door 7. Specifically, the card slot includes a limiting slot 10 and a giving slot 11 which are L-shaped to each other, and a notch is formed on the side of the giving slot 11 away from the limiting slot 10. The limiting slot 10 is used to limit the up and down, front and back directions of the bin cover 9. A fixing slot 12 is formed on the side of the shell corresponding to the bin door 7. One end of the bin cover 9 extends inward to form an arc-shaped portion, and a convex buckle 95 is provided on the inner wall of the arc-shaped portion. The fixing slot 12 and the convex buckle 95 are locked and matched to achieve the limitation of the left and right directions of the bin cover 9. The above scheme enables the bin cover 9 to be limited and fixed in the up and down, left and right, front and back directions when closing the bin door 7, ensuring the installation stability. The bin cover 9 can only be slid out when the user applies a greater force to the right until the second upper buckle 93 and the second lower buckle 94 slide to the giving slot 11. When the convex buckle 95 exits the fixing slot 12, it can be rotated outward through the slot to open the bin door 7.

[0034] In this embodiment, the pressing plate 8 is a stainless steel pressing plate, and the free end 81 of the pressing plate 8 is a U-shaped structure bent inward, thereby achieving elastic extrusion and positioning of the battery 15 to ensure assembly stability.

[0035] In this embodiment, foot pad installation grooves are provided at the four corners of the lower housing cover 2 , and foot pads 13 are fixedly installed in the foot pad installation grooves.

[0036] The present utility model also provides a sensor device, including the shell cover mechanism, the battery box group and the sensor installed on the shell cover mechanism described in the above embodiment. The shell is respectively provided with slide rails 16 on the left and right sides corresponding to the accommodating compartment 6, and the left and right sides of the battery box group are respectively provided with slide grooves 17. The battery box group is installed in the accommodating compartment 6 through the slide grooves 17 and the slide rails 16, thereby ensuring the assembly accuracy and stability of the battery box group in the accommodating compartment 6.

[0037] In this embodiment, the shell includes an upper shell cover 1 and a lower shell cover 2 assembled together, and a compartment door 7 is formed on one side between the upper shell cover 1 and the lower shell cover 2. A fixing frame 3 is installed between the upper shell cover 1 and the lower shell cover 2, and a main board 4 and a power board 5 are installed on opposite sides of the fixing frame 3 respectively. The main board 4 is located on the side of the fixing frame 3 close to the upper shell cover 1, and the power board 5 is located on the side of the fixing frame 3 close to the lower shell cover 2. A mounting bracket 22 is installed on the side of the lower shell cover 2 away from the upper shell cover 1, and the sensor is clamped on the mounting bracket 22.

[0038] At present, most of the sensor devices on the market directly fix the battery 15 in the box 14 inside the shell, and use springs, etc. to achieve conductivity, which cannot make good use of the internal space of the shell. When replacing the battery 15, the sensor device needs to be removed before it can be replaced. The operation is cumbersome and inconvenient, affecting the user's replacement experience. To solve the above problems, in this embodiment, a positive spring pin 51 and a negative spring pin 52 are provided on the power board 5, and the battery box group includes a box 14 and a battery 15 installed in the box 14. A positive spring clip 18 and a negative spring clip 19 are respectively provided on both sides of the interior of the box 14. A positive contact spring 20 and a negative contact spring 21 are fixedly mounted on the outer wall of 4. One end of the positive contact spring 20 is fixedly welded to the positive spring 18 to form an electrical connection, and the other end is detachably connected to the positive spring pin 51 to achieve movable conductive contact. One end of the negative contact spring 21 is fixedly welded to the negative spring 19 to form an electrical connection, and the other end is detachably connected to the negative spring pin 52 to achieve movable conductive contact. This arrangement enables the battery pack to be taken out independently, making replacement operation more convenient, and its structural layout and power supply method are more reasonable, which not only makes good use of the internal space of the product, but also improves the user's replacement experience.

[0039] The assembly process of this embodiment is as follows:

[0040] First, fix the power board 5 and the main board 4 to both sides of the fixing frame 3 with screws, and then assemble the fixing frame 3 with the upper shell cover 1 by buckling;

[0041] Furthermore, the compartment cover 9 is mounted on the outside of the pressure plate 8 to form a compartment cover assembly. At this time, the front-back and top-bottom freedom between the pressure plate 8 and the compartment cover 9 is restricted by the first upper buckle 91 and the first lower buckle 92, and there is a certain amount of movement space in the left-right direction.

[0042] Furthermore, the bin cover assembly is rotatably connected to the bin door 7 via a rotating shaft;

[0043] Furthermore, the lower shell cover 2 is mounted on one side of the upper shell cover 1 by screws, and the foot pad 13 is then attached to the foot pad 13 mounting groove;

[0044] Further, the compartment cover assembly is rotated to open (the compartment cover 9 must first be pushed to the right so that the second upper buckle 93 and the second lower buckle 94 on the compartment cover 9 slide into the clearance groove 11. When the protruding buckle 95 exits the fixing groove 12, it can be rotated outward through the notch to open the compartment door 7).

[0045] Furthermore, the battery box assembly is installed in the receiving compartment 6 by slidingly cooperating with the slide groove 17 and the slide rail 16;

[0046] Furthermore, the compartment cover assembly is rotated inwardly so that the compartment cover 9 is pushed to the left, and the compartment cover assembly closes the compartment door 7. At this time, the free end 81 of the pressure plate 8 is bent inward, thereby elastically squeezing and limiting the battery 15, ensuring assembly stability and preventing it from shaking inside.

[0047] Further, the mounting bracket 22 is fixed at the desired position, and the sensor is then clipped onto the mounting bracket 22;

[0048] Furthermore, when the battery 15 needs to be replaced, the compartment cover assembly can be opened as described above, the battery box group can be taken out, the battery 15 can be replaced, the battery box group can be reinserted into the accommodating compartment 6, and the compartment cover assembly can be closed.
