Description

Technical Field

[0001] This utility model relates to a sensing device, and more particularly to a roll sensing device. Background Technology

[0002] A roll sensor is an instrument used to measure the roll angle of a vehicle, and it is widely used in fields requiring attitude detection and control, such as industrial robots, aerospace, and consumer electronics. Existing roll sensors generally use a single dual-axis accelerometer to collect acceleration data in two directions to obtain the roll angle. However, dual-axis accelerometers are either expensive or have poor accuracy and stability; their complex structure also increases the risk of malfunctions, such as signal interference. Therefore, there is a need to design a roll sensor that is simple in structure, low in cost, stable and reliable, and less prone to failure even after long-term use. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a roll sensing device that is simple in structure, low in cost, and stable and reliable.

[0004] The roll sensing device of this utility model includes a protective shell with one open end, an end cap at the opening of the protective shell, a mounting hole penetrating the end cap in the middle of the end cap, a connector in the mounting hole, and a mounting bracket inside the protective shell. The mounting bracket includes a top plate, a bottom plate, and at least two connecting plates. The top plate is fixedly connected to the end cap, and the surface of the top plate has positioning holes adapted to the connector. One end of the connecting plate is fixed to the top plate, and the other end of the connecting plate is fixed to the bottom plate. Several fixing seats are provided on the connecting plates, and fixing holes penetrating the fixing seats are provided on the surface of the fixing seats. Two single-axis acceleration sensors with mutually perpendicular main shafts are provided inside the protective shell and fixed on the fixing seats.

[0005] The advantage of this roll sensing device is that it has two single-axis acceleration sensors with mutually perpendicular main axes installed in its protective housing via a mounting bracket. The two single-axis acceleration sensors can sense the X-axis and Y-axis acceleration of the carrier respectively, and then the host computer system can calculate the roll angle of the carrier based on the X-axis and Y-axis acceleration data.

[0006] Compared to existing roll sensing devices that use dual-axis accelerometers, two single-axis accelerometers are less expensive while ensuring measurement accuracy. The overall structure of the sensing device is simpler, and it is less prone to failure during long-term use, ensuring reliable and stable operation.

[0007] Furthermore, in the roll sensing device of this utility model, the surface of the top plate is provided with a clamping ring, the inner wall of the mounting hole is provided with an annular flange, and the body of the connector is disposed between the annular flange and the clamping ring.

[0008] The annular flange and clamping ring enable the fixing and positioning of the mating plug.

[0009] Furthermore, in the roll sensing device of this utility model, the base plate is an annular base plate, and an annular groove is formed on the outer circumferential surface of the annular base plate.

[0010] The ring-shaped base plate reduces the weight of the base plate, thereby further reducing the weight of the roll sensor, achieving a lightweight design and facilitating the installation and transportation of the roll sensor by operators.

[0011] The annular groove on the outer circumference of the annular base plate is used to install the buffer ring. The buffer ring is in close contact with the inner wall of the protective shell, which can effectively prevent the mounting bracket from shaking inside the protective shell, and also reduce the impact of external impact vibration on the single-axis sensor.

[0012] Furthermore, in the roll sensing device of this utility model, there are two connecting plates, and each connecting plate is provided with two fixing seats.

[0013] The two connecting plates and the two mounting brackets on them enable a stable installation of the single-axis accelerometer.

[0014] Furthermore, in the roll sensing device of this utility model, the end cap is fixed to the protective shell by screws, and the surface of the end cap is provided with threaded holes for connecting to external equipment.

[0015] The protective shell and end cap can be securely connected by screws, and the threaded holes on the surface of the end cap facilitate its connection and fixation with external equipment.

[0016] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following describes the embodiments of this utility model in detail.

Detailed Implementation

[0023] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0024] Example 1: See Figures 1 to 5 The roll sensing device of this embodiment includes a protective shell 1 with one open end, an end cap 2 at the opening of the protective shell, a mounting hole 3 penetrating the end cap in the middle of the end cap, a connector 4 in the mounting hole, and a mounting bracket 5 inside the protective shell. The mounting bracket includes a top plate 6, a bottom plate 7 and at least two connecting plates 8. The top plate is fixedly connected to the end cap, and the surface of the top plate has positioning holes 9 that are adapted to the connector. One end of the connecting plate is fixed to the top plate, and the other end of the connecting plate is fixed to the bottom plate. A plurality of fixing seats 10 are provided on the connecting plate, and fixing holes 11 penetrating the fixing seats are provided on the surface of the fixing seats. Two single-axis acceleration sensors (not shown in the figure) with mutually perpendicular main shafts are provided inside the protective shell, and the single-axis acceleration sensors are fixed on the fixing seats.

[0025] The advantage of this roll sensing device is that it has two single-axis acceleration sensors with mutually perpendicular main axes installed in its protective housing via a mounting bracket. The two single-axis acceleration sensors can sense the X-axis and Y-axis acceleration of the carrier respectively, and then the host computer system can calculate the roll angle of the carrier based on the X-axis and Y-axis acceleration data.

[0026] Compared to existing roll sensing devices that use dual-axis accelerometers, two single-axis accelerometers are less expensive while ensuring measurement accuracy. The overall structure of the sensing device is simpler, and it is less prone to failure during long-term use, ensuring reliable and stable operation.

[0027] The protective shell protects internal components such as the single-axis accelerometer. It is preferably a cylindrical structure with an opening at the top, and the end cap is fixed to the opening by screws or threads.

[0028] The end cap is used to seal the protective housing and install the connector. In this embodiment, the end cap is installed at the top opening of the housing with screws. Its surface is provided with threaded holes for connecting to external equipment, and a mounting hole penetrating the end cap is provided in its center. The mounting hole is adapted to the connector. A sealing groove 12 is provided on the circumferential surface of the connector body for installing a sealing ring, thereby achieving a seal on the protective housing. Similarly, the circumferential surface of the end cap is also provided with a sealing groove to seal the protective housing.

[0029] The connector is used for electrical connection between external devices and components such as single-axis accelerometers. In this embodiment, the connector is a six-pin watertight connector.

[0030] The mounting bracket is used to mount a single-axis accelerometer. Its top plate has positioning holes that mate with the connector for positioning and wiring. The top plate is fixed to the inner surface of the end cap with screws, and the bottom plate is in close contact with the bottom and side walls of the protective housing.

[0031] The top plate and the bottom plate are connected by at least two connecting plates, and the inner side of the connecting plates is provided with a mounting bracket for fixing a single-axis acceleration sensor (not shown) or a circuit board.

[0032] This type of mounting bracket not only enables the installation of components such as single-axis accelerometers, but also has a relatively simple structure and light weight, thereby reducing the overall weight of the instrument and improving its lightweight level.

[0033] Preferably, the surface of the top plate is provided with a clamping ring 13, the inner wall of the mounting hole is provided with an annular flange 14, and the body of the connector is disposed between the annular flange and the clamping ring.

[0034] The annular flange and clamping ring enable the fixing and positioning of the mating plug.

[0035] Specifically, the clamping ring is located at the positioning hole in the middle of the top plate, with one end fixed to the top plate. The central hole of the clamping ring communicates with the positioning hole, and the annular flange is located at the end of the inner wall of the mounting hole near the outer side of the end cap. During installation, the end of the clamping ring is inserted into the mounting hole. After the top plate and end cap are fixed, the end of the clamping ring presses the body of the connector against the annular flange, thereby fixing the connector. Its structure is relatively simple, and the connection is firm and reliable.

[0036] Preferably, the base plate is an annular base plate, and an annular groove 15 is formed on the outer circumferential surface of the annular base plate.

[0037] The ring-shaped base plate reduces the weight of the base plate, thereby further reducing the weight of the roll sensor, achieving a lightweight design and facilitating the installation and transportation of the roll sensor by operators.

[0038] The annular groove on the outer circumference of the annular base plate is used to install the buffer ring. The buffer ring is in close contact with the inner wall of the protective shell, which can effectively prevent the mounting bracket from shaking inside the protective shell, and also reduce the impact of external impact vibration on the single-axis sensor.

[0039] Preferably, there are two connecting plates, and each connecting plate is provided with two fixing seats.

[0040] The two connecting plates and the two mounting brackets on them enable a stable installation of the single-axis accelerometer.

[0041] Preferably, the end cap is fixed to the protective shell by screws, and the surface of the end cap is provided with threaded holes 16 for connecting to external equipment.

[0042] The protective shell and end cap can be securely connected by screws, and the threaded holes on the surface of the end cap facilitate its connection and fixation with external equipment.
