[0034] like Figure 1 and Figure 2 As shown, the present application provides a signal acquisition device with high integration, capable of docking with multiple sensing elements and simultaneously collecting signals of multiple sensing elements, and occupying a smaller space. The signal acquisition device mainly includes two parts: a housing 1 and a signal acquisition component 2.

[0035] The housing 1 is the main bearing structure of the signal acquisition device, which is used to protect and carry the signal acquisition component 2. The housing 1 is provided with a housing cavity, which provides a structurally stable installation space for the signal acquisition component 2 to ensure that all components can be placed firmly. At the same time, the housing 1 is also provided with a connecting port, which allows the housing cavity to be connected with the outside world, and provides a necessary channel for the connection between the sensing element and the signal acquisition component 2. The signal transmission terminal of the sensing element extends into the housing cavity through the connecting port and is connected to the signal acquisition component 2.

[0036] The signal acquisition component 2 is the core functional part of the signal acquisition device, which includes a circuit board 21, a signal processing element 22 and a plurality of connection ports 23. The circuit board 21, as the basis of the entire component, is responsible for carrying the signal processing element 22 and each connection port 23. The signal processing element 22 is responsible for receiving and processing the electrical signal from the sensing element. The connection port 23 is used to connect to the signal transmission terminal of the sensing element to realize the signal transmission between the sensing element and the signal acquisition component 2. The number of connection ports 23 can be two, three, four, etc., and the actual number of connection ports 23 can be selected according to actual use requirements. Each connection port 23 is arranged toward the connecting port, so that when the signal transmission terminal of the sensing element is inserted into the connecting port, it can be directly connected to the connection port 23.

[0037] It is worth mentioning that the present application enables the signal acquisition device to realize the electrical signal acquisition of multiple sensing elements by providing multiple connection ports 23. This design not only improves the integration of the device and saves valuable space, but also makes the installation process more convenient and efficient.

[0038] In the present application, the connection method between the connection port 23 and the signal transmission terminal of the sensing element is not specifically limited. The connection between the connection port 23 and the signal transmission terminal of the sensing element can be fixed or detachably connected.

[0039] As a preferred embodiment, the connection port 23 is detachably connected to the signal transmission terminal of the sensing element. Specifically, the connection port 23 includes a movable pressure plate and a docking contact for connecting with the signal transmission terminal, and the movable pressure plate is flippably arranged on one side of the docking contact. By flipping the movable pressure plate, the docking contact can be exposed or shielded; when the signal transmission terminal contacts with the docking contact, the signal transmission terminal is clamped between the movable pressure plate and the docking contact by flipping the movable pressure plate, thereby ensuring the stability of the contact between the signal transmission terminal and the docking contact during use. The connection port 23 is more convenient for the installation and use of the sensing element.

For example, the signal acquisition component 2 includes four connection ports 23, and the four connection ports 23 are connection ports 23 connected to a thin film pressure sensing piece. In another embodiment of the present application, each connection port 23 includes at least two connection ports with different structures. For example, the signal acquisition component 2 includes four connection ports 23, two of the four connection ports 23 are connection ports 23 connected to a thin film pressure sensing piece, and the other two connection ports 23 are connection ports 23 connected to a thin film temperature sensing piece. In order to adapt to the signal processing of the thin film pressure sensing piece and the thin film temperature sensing piece, the signal acquisition component 2 also needs to be equipped with a signal processing element for processing the pressure signal and a signal processing element for processing the temperature signal according to actual conditions.

[0041] In one embodiment of the present application, the number of the circuit board 21 is one, and the circuit board 21 is connected to a connection port 23 of one or more structures to realize signal collection of one or more sensing elements.

As a specific implementation, the signal acquisition component 2 has two connection ports 23, and the two connection ports 23 are provided at the same side in the thickness direction of the circuit board 21.

[0044] In another embodiment of the present application, each connection port 23 provided at the first end is provided at both sides of the circuit board 21 along the thickness direction of the circuit board 21. This arrangement can make the overall structure of the signal acquisition component 2 more compact, thereby making the overall structure of the signal acquisition device more compact and making the signal acquisition device more integrated.

[0045] In another embodiment of the present application, each connection port 23 can also be provided at different ends of the circuit board 21, so as to avoid excessive concentration of each connection port 23 at one end of the circuit board 21. Specifically, the circuit board 21 is provided with multiple ends at different positions, and at least two ends are provided with connection ports; the housing 1 is provided with a communication port at a position corresponding to the end provided with the connection port 23.

They can be both arranged at one end of the shell 11, or they can also be respectively arranged at both ends of the shell 11. Such a design is more flexible and can adapt to the needs of different scenarios.
