Description

Technical Field

[0001] This utility model relates to the field of sensor arrangement technology, specifically to a housing connection base for arranging wireless tilt sensors. Background Technology

[0002] A wireless tilt sensor is an intelligent sensing device based on advanced microelectromechanical systems (MEMS) technology or accelerometer principles, used to measure the tilt angle of an object in space in real time. Its core function is to capture changes in the gravitational acceleration component through a built-in high-precision sensor unit, convert this data into angle data after processing by a microprocessor, and then transmit the data to a terminal system via a wireless communication module (such as LoRa, ZigBee, Bluetooth, etc.) to achieve remote monitoring and control.

[0003] A common wireless tilt sensor can be found in patent document CN217389036U, which discloses a wireless tilt sensor. This device includes a housing, a main circuit board, a bent antenna, and a top cover. The side wall of the housing has mounting holes, and an antenna mount is fixed in the mounting holes. The main circuit board is fixed inside the housing and connected to the bent antenna via a wire mount. The top cover fixes and closes the opening of the housing. A hollow ring is set inside the mounting holes. A heat-conducting component is set on the outside of the hollow ring, which is located inside the housing. The antenna mount is located inside the housing and is inserted and fixed to the bent antenna, which is located outside the housing, and clamps the hollow ring. The hollow ring expands when heated to tighten the antenna mount, achieving temperature-controlled tightness and more reliable and durable use.

[0004] When arranging the main circuit board in the above-mentioned device, the main circuit board is directly installed inside the casing. This will bring certain problems: First, the space inside the casing is limited, which will make the installation operation inconvenient. Second, the lack of reference structure inside the casing makes it impossible to accurately control the position of the main circuit board, which will cause the position of the main circuit board and other components to deviate to some extent. Utility Model Content

[0005] This invention provides a housing connection base for arranging wireless tilt sensors, thereby solving the technical problems of inconvenient operation during the assembly of wireless tilt sensors and low positional accuracy of the main circuit board and other components in the prior art.

[0006] To solve the above problems, the housing connection base for arranging wireless tilt sensors provided by this utility model adopts the following technical solution:

[0007] A housing connection base for arranging a wireless tilt sensor includes:

[0008] The base has a circumferential dimension that matches the inner wall dimension of the housing, and the outer circumference of the base has a snap-fit ​​structure that slides into the inner wall of the housing so that the base can slide into the housing. The upper surface of the base has a groove for mounting the PCB board of the wireless tilt sensor.

[0009] The enclosure structure includes multiple enclosures fixed to the upper surface of the base. The enclosures are connected in sequence and surround the upper side of the lower groove. A placement groove for placing the battery of the wireless tilt sensor is formed between the enclosures.

[0010] The beneficial effects of the housing connection base for arranging a wireless tilt sensor provided by this utility model are as follows: Before the housing is placed, the base and the surrounding plate structure form a pre-assembled structure, which is used to place the PCB board and the battery, respectively. Since this placement operation is carried out outside the housing, the operating space is large and the difficulty is low. Moreover, the groove and the placement slot provide a limiting reference for the placement of the PCB board and the battery. The operator can quickly place the PCB board and the battery in the corresponding position, which fully ensures the placement accuracy of the wireless tilt sensor. After pre-assembly, the wireless tilt sensor can be quickly placed into the housing through the snap-fit ​​structure, which also ensures the assembly efficiency. This effectively solves the technical problems of inconvenient operation and low positional accuracy of the main circuit board and other components during the assembly of wireless tilt sensors in the prior art.

[0011] Furthermore, both the lower groove and the placement groove are rectangular grooves, with the size of the placement groove being larger than the size of the lower groove.

[0012] Furthermore, the base is also provided with a wiring structure for arranging the cables of the PCB board and the battery.

[0013] Furthermore, the wiring structure is a notch or groove formed on the base, which connects the lower recess and the placement groove. This design not only enables wiring but also makes full use of the base space, thereby improving the base's utilization rate.

[0014] Furthermore, the surrounding plate corresponding to the notch position also has a notch to facilitate the connection of the notch to the placement slot.

[0015] Furthermore, the inner diameter of the lower groove is larger than the size of the PCB board to reduce placement difficulty. The lower groove has mounting holes for fixing the PCB board. Since the lower groove is located lower and is more difficult to arrange than the placement slot, sufficient dimensional leeway must be provided to further facilitate the installation of the PCB board.

[0016] Furthermore, the number of mounting holes is four, distributed at the four corners of the lower groove.

[0017] Furthermore, the mounting structure is a protrusion and recess formed on the outer periphery of the base. The protrusion and recess have the advantages of stable mounting and easy installation and removal.

[0018] Furthermore, the protrusions and recesses are multiple vertically extending ribs formed on the outer periphery of the base, with the multiple ribs evenly distributed at intervals on the outer periphery of the base, and the outer shell is provided with slots for the ribs to be engaged.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0027] An embodiment of the housing connection base for arranging a wireless tilt sensor provided by this utility model:

[0028] like Figures 1 to 3As shown, a housing connection base for arranging a wireless tilt sensor is mainly used for pre-installing the various electrical components of the wireless tilt sensor, which are then placed into the housing as a whole, improving assembly accuracy and reducing assembly difficulty. It includes a base 1 and a surrounding plate structure.

[0029] The circumferential dimensions of the base 1 are adapted to the inner wall dimensions of the housing, and the outer circumference of the base 1 has a snap-fit ​​structure that slides into the inner wall of the housing, so that the base 1 can slide into the housing. The upper surface of the base 1 has a lower groove 4, and the PCB board 2 of the wireless tilt sensor is installed in the lower groove 4.

[0030] The enclosure structure includes multiple enclosures 3 fixed to the upper surface of the base 1. Each enclosure 3 is connected in sequence and surrounds the upper side of the lower groove 4. A placement groove 5 for placing the battery of the wireless tilt sensor is formed between each enclosure 3.

[0031] Specifically, both the lower groove 4 and the placement groove 5 are rectangular grooves, and the size of the placement groove 5 is larger than the size of the lower groove 4.

[0032] In this embodiment, a wiring structure is also arranged on the base 1 for arranging the cables of the PCB board 2 and the battery. Specifically, the wiring structure is a notch 6 formed on the base 1, which connects the lower groove 4 and the placement groove 5. This arrangement not only realizes the wiring but also makes full use of the space of the base 1, improving the utilization rate of the base 1.

[0033] like Figure 1 and Figure 2 As shown, the surrounding plate 3 corresponding to the notch slot 6 also has a notch 7 to facilitate the connection of the notch slot 6 with the placement slot 5. In other embodiments, the surrounding plate 3 corresponding to the notch slot 6 may not have a notch, but instead has a cable passage hole for the cable to pass through.

[0034] In this embodiment, the inner diameter of the lower groove 4 is larger than that of the PCB board 2 to reduce placement difficulty. The lower groove 4 has mounting holes 8 for fixing the PCB board 2. Since the lower groove 4 is located lower and is more difficult to arrange than the placement slot 5, a margin must be left in its size to further facilitate the installation of the PCB board 2.

[0035] In this embodiment, there are four mounting holes 8, distributed at the four corners of the lower groove 4. In other embodiments, the number of mounting holes 8 can be adjusted according to actual needs, and there can be two or three.

[0036] Finally, in this embodiment, reference Figures 1 to 3The locking structure consists of protruding and recessed parts formed on the outer periphery of the base 1. These parts offer advantages such as stable locking and easy assembly / disassembly. Each protruding part comprises multiple vertically extending ribs 9 formed on the outer periphery of the base 1, evenly spaced apart. The outer shell has slots for the ribs 9 to engage. This locking method is similar to a mortise and tenon joint, ensuring a tight and stable connection.

[0037] The working principle of the housing connection base for arranging wireless tilt sensors provided by this utility model is as follows: Before the housing is placed in, the base 1 and the surrounding plate structure form a pre-assembled structure, which are used to place the PCB board 2 and the battery respectively. First, the PCB board 2 is placed in the lower groove 4, and the PCB is fixed in each mounting hole 8 by screws. Then, the battery is arranged in the placement groove 5. During this process, the notch groove 6 and the notch are used for wiring. After the arrangement is completed, the entire housing connection base is placed into the housing through the snap-fit ​​structure, and then the cover of the housing is snapped on.
