[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] Example 1

[0048] Please refer to Figure 1-Figure 9 This embodiment provides a human body occupancy sensor, including:

[0049] A sensor body 4, wherein the sensor body 4 detects pressure data when under pressure, wherein the pressure data includes a pressure value and a pressure distribution;

[0050] A sensor chip 5, on which a control circuit adapted to the sensor body 4 is disposed, and the sensor chip 5 is electrically connected to the sensor body 4; the sensor chip 5 comprises at least two electrodes 501, and the two electrodes 501 are electrically connected to connection terminals 604 respectively;

[0051] The connecting member 6 is provided with a connecting portion, the connecting terminal 604 is mounted on the connecting portion, and the connecting portion is protected by glue injection.

[0052] Specifically, the human occupancy sensor is used to detect whether a driver or a passenger is sitting on the seat. Generally, the human occupancy sensor is connected to the vehicle connector docking terminal 7 through a connector for power supply and signal transmission. The traditional human occupancy sensor is connected to the connector through an additional wiring harness. This connection method increases the number of wiring harnesses inside the seat, which is easy to interfere with the installation of other functional accessories in the seat, causing inconvenience in installation and problems such as the seat being messy and difficult to repair.

[0053] Therefore, the utility model aims to provide a human occupancy sensor, which eliminates the additional wiring harness and is used to solve the above-mentioned problem and achieve avoidance of other functional accessories.

[0054] Specifically, the sensor body 4 is a pressure sensor. When a person sits on the car seat and presses the sensor body 4, the sensor body 4 can detect the pressure value at each pressure point and the position distribution of different pressure points. The sensor chip 5 is provided with a control circuit adapted to the sensor body 4, which is mainly used to process the data detected by the sensor body 4 and transmit data between the vehicle, and is also used to power the sensor body 4 by connecting with the vehicle connector docking end 7. The sensor chip 5 has a free end, and two electrodes 501 of the sensor chip 5 are provided on the free end, and the two electrodes 501 are respectively connected to two connection terminals 604. The connector 6 is similar to a plug, and a connection part is provided on the connector 6, and the connection terminal 604 is installed on the connection part. The connection part is sealed by injecting glue, and then the connection terminal 604 is fixed on the connection part, and the connection part is protected at the same time.

[0055] Furthermore, the connecting member 6 comprises:

[0056] A connector housing 601, wherein the connector housing 601 is hollow inside and connected at both ends, wherein one end forms an interface 602 for electrical connection with a vehicle, and a side wall of the other end is provided with a notch to form a mounting groove 603, wherein the connecting portion is formed in the mounting groove 603;

[0057] The blocking member 605 fills the installation groove 603 and is crimped to fix the connecting terminal 604 . The blocking member 605 is formed by injecting glue into the installation groove 603 .

[0058] Specifically, the connector 6 is composed of at least the connector housing 601 and the blocking member 605. The connector housing 601 is hollow inside, and one end of the connector housing 601 forms the interface 602 for connecting with the vehicle connector docking end 7, and the top wall of the other end is provided with a notch, so that the bottom wall and two side walls of the connector housing 601 cooperate to form the mounting groove 603, and the installation of the mounting groove 603 is convenient for installing the connecting terminal 604, and the connecting portion for installing the connecting terminal 604 is formed in the mounting groove 603, and the free end of the sensor chip 5 is electrically connected to the connecting terminal 604 and the two are tightly fixed, and the connecting terminal 604 extends from the mounting groove 603 to the interface 602. The blocking member 605 is formed by injecting glue into the installation groove 603. When injecting glue, the glue wraps the connecting terminal 604 and the installation part. After the blocking member 605 is formed, it is embedded in the installation groove 603. The purpose of setting the blocking member 605 is to seal the installation groove 603 and fix the electrode 501 of the sensor film 5 and the connecting terminal 604 at the same time to prevent the sensor film 5 and the connecting terminal 604 from shaking in the installation groove 603, resulting in poor contact between the two.

[0059] During installation, the connecting terminal 604 and the electrode 501 of the sensor film 5 are installed in the installation groove 603, and the connecting component 6 is matched with the injection mold to inject glue into the installation groove 603. After the glue liquid solidifies, the sealing component 605 is formed, and the connecting component 6, the connecting terminal 604 and the electrode 501 of the sensor film 5 are connected through the sealing component 605.

[0060] Furthermore, a blocking structure is provided on one side of the mounting groove 603 close to the interface 602, and the blocking structure is used to prevent the glue from flowing toward the pin direction of the connecting terminal 604. A shielding structure is provided on the glue injection mold, and the glue injection mold cooperates with the mounting groove 603 during glue injection to prevent the glue from flowing out of the mounting groove 603.

[0061] Furthermore, at least one limiting structure is provided on the side wall of the installation groove 603 , and the limiting structure is used to limit the blocking member 605 .

[0062] Specifically, since the end of the connecting member 6 is open and a notch is provided on the top surface, in order to prevent the blocking member 605 from falling out of the installation groove 603, a limiting structure is provided in the installation groove 603 in advance. By providing the limiting structure, the blocking member 605 is snap-connected with the limiting structure after molding, thereby limiting the position of the blocking member 605 and preventing the blocking member 605 from falling out of the installation groove 603.

[0063] Furthermore, the limiting structure includes an outer protrusion 611 provided on the side wall of the mounting groove 603 , and the outer protrusion 611 extends in a direction perpendicular to the bottom wall of the mounting groove 603 .

[0064] Specifically, the purpose of setting the limiting structure is to limit the shape of the inner wall of the installation groove 603, so that the blocking member 605 forms a different shape after the glue is injected. In this embodiment, the limiting structure includes an outer protrusion 611 formed on the inner wall of the installation groove 603. When the glue is injected into the installation groove 603, a groove is formed at the position of the blocking member 605 corresponding to the outer protrusion 611 after the glue is formed. The groove is engaged with the outer protrusion 611 to limit the blocking member 605 from moving in a direction parallel to the side wall of the installation groove 603 and parallel to the bottom wall of the installation groove 603, thereby preventing the blocking member 605 from falling off from the installation groove 603.

[0065] Furthermore, a gap 612 is provided between the outer protrusion 611 and the bottom wall of the installation groove 603 , and the glue filling the installation groove 603 can fill the gap 612 , so that the sealing member 605 forms an outer protrusion structure at the position of the gap 612 after molding.

[0066] Specifically, when the outer protrusion 611 is provided on the side wall of the mounting groove 603, the outer protrusion 611 extends in a direction perpendicular to the bottom wall of the mounting groove 603, but does not extend to the bottom wall of the mounting groove 603. There is a certain distance between the outer protrusion 611 and the bottom wall of the mounting groove 603, thereby forming a gap 612 between the outer protrusion 611 and the mounting groove 603. When glue is injected into the mounting groove 603, the glue will flow into the gap 612, and then when the glue forms the sealing member 605, the sealing member 605 forms a protrusion at a position corresponding to the gap 612, and the protrusion is clamped with the bottom of the outer protrusion 611 to limit the movement of the sealing member 605 in a direction perpendicular to the bottom wall of the mounting groove 603 and away from the bottom wall of the mounting groove 603, thereby preventing the sealing member 605 from falling off from the mounting groove 603.

[0067] In other embodiments, the limiting structure can also be an inner groove formed on the inner wall of the installation groove 603. The structure of the inner groove is not shown in the accompanying drawings. The inner groove is arranged at the position of the above-mentioned outer protrusion 611. When injecting glue into the installation groove 603, the glue liquid is formed to form a protrusion at the position of the sealing member 605 corresponding to the inner groove. The protrusion is engaged with the inner groove to limit the movement of the sealing member 605 in a direction parallel to the side wall of the installation groove 603 and parallel to the bottom wall of the installation groove 603, thereby preventing the sealing member 605 from falling off from the installation groove 603. When the inner groove is set on the side wall of the mounting groove 603, the inner groove extends in a direction perpendicular to the bottom wall of the mounting groove 603, and a shield is set at one end of the inner groove away from the bottom wall of the mounting groove 603. The protrusion formed on the blocking member 605 corresponding to the inner groove abuts against the shield on the inner groove to limit the blocking member 605 from moving in a direction perpendicular to the bottom wall of the mounting groove 603 and away from the bottom wall of the mounting groove 603, thereby preventing the blocking member 605 from falling off from the mounting groove 603.

[0068] Furthermore, a notch 613 is further provided on the bottom wall of the installation groove 603 , and is used to form an outward convex structure corresponding to the position of the notch 613 after the blocking member 605 is formed.

[0069] Specifically, the notch 613 is a sunken groove on the bottom wall of the mounting groove 603, and the position where the connecting terminal 604 and the electrode 501 are connected is located at the opening of the notch 613. By setting the notch 613, when glue is injected into the mounting groove 603, the glue can flow to the bottom of the connecting terminal 604, thereby wrapping the connecting terminal 604.

[0070] Furthermore, a third clamping portion 615 is provided on a side wall of the interface 602 , and the third clamping portion 615 is used for clamping the vehicle connector docking end 7 .

[0071] Specifically, by setting the third clamping portion 615 on the side wall of the interface 602, when the interface 602 is connected to the vehicle connector docking end 7, the third clamping portion 615 can be clamped with the vehicle connector docking end 7 to improve the tightness of the connection between the interface 602 and the vehicle. The third clamping portion 615 is a through hole opened on the side wall of the interface 602.

[0072] Furthermore, a fixing portion 616 is provided between the interior of the interface 602 and the mounting groove 603 , and the fixing portion 616 is used to limit the connection terminal 604 .

[0073] Specifically, the fixing portion 616 is disposed in the connecting member 6, a positioning column is provided on the fixing portion 616, and a through hole for being sleeved on the positioning column is provided on the connecting terminal 604. The connecting terminal 604 can be clamped by the cooperation of the positioning column and the through hole, thereby limiting the position of the connecting terminal 604.

By injecting liquid into the glue injection cavity, no additional glue injection mold is required, which ensures that the glue injection is more convenient, and at the same time, the glue liquid is prevented from flowing out and flowing to the connecting terminal 604. By setting a snap-fit ​​groove 606 on one side of the mounting groove 603, the snap-fit ​​groove 606 is used for the connector top cover 607 to snap-fit ​​and fix, so that the connector top cover 607 and the mounting groove 603 are tightly covered. The glue injection cavity is provided with at least one glue injection port 614. In this embodiment, the glue injection port 614 is arranged at a position of the connector top cover 607 corresponding to the snap-fit ​​groove 606.
