Referring to fig. 1, some embodiments of the present utility model provide a detection apparatus 100. The detection device 100 can be used for a sensor 200 to be detected, and the detection device 100 comprises a base body 10, an abutting piece 20 and a locking piece 30. The base 10 is provided with a sensing element 11, and the sensing element 11 can be used for placing the sensor 200 to be detected.

The abutment 20 may include a pressing portion 21 and an abutment 22 connected to each other. The pressing portion 21 is rotatably mounted to the base 10, and for example, the pressing portion 21 and the base 10 may be connected by a rotation shaft, a link mechanism, or the like. The pressing portion 21 may be used for contacting the sensor to be detected 200 and driving the sensor to be detected 200 to move toward the sensing element 11. The locking member 30 is attachable to the housing 10, the locking member 30 has a stopper 31, the stopper 31 has an abutting position abutting against the abutting portion 22, and the stopper 31 can limit the abutting portion 22 in a direction away from the sensing member 11 at the abutting position.

The operation of the detection device 100 will be described below using the MEMS sensor as the sensor 200 to be detected.

As shown in fig. 1, the sensor to be detected may be placed at the sensing piece 11 of the base 10, for example, the sensor may be placed above the sensing piece 11. The abutment 20 can then be rotated so that the pressing portion 21 of the abutment 20 can rotate relative to the housing 10 and abut against the sensor. At this time, the sensor is movable in a direction approaching the sensing element 11 by the pressing portion 21, and is in contact with the sensing element 11.

The pressing portion 21 is brought into contact with the sensor, and the abutting portion 22 is also rotated around the seat body 10 by the pressing portion 21, and abuts against the stopper portion 31 of the locking member 30. Because the limiting portion 31 can limit the abutting portion 22 in the direction away from the sensing element 11, after the external force is removed from the pressing portion 21, the pressing portion 21 can continuously apply pressure to the sensor under the action of the limiting portion 31, so that the sensing element 11 can conveniently detect the sensor.

In summary, when the sensor 200 to be detected is placed at the sensing element 11, the pressing portion 21 of the abutment element 20 can rotate to the position where the sensor 200 to be detected is located, and when pressure is applied to the sensor, the abutment portion 22 of the abutment element 20 can abut against the limiting portion 31 of the locking element 30, so as to realize self-locking of the abutment element 20, so that the abutment element 20 can always apply pressure to the sensor after external force is removed, and thus the sensor is detected.

By such arrangement, on the basis of simplifying the structure of the detection device 100, the detection mode of the detection device 100 is simplified, and the operation of a user is facilitated.

As shown in fig. 2, in some embodiments, the pressing portion 21 and the base 10 may be rotatably connected by a rotation shaft. The rotating shaft can be sleeved with a torsion spring, and the pressing part 21 can rotate 70-120 degrees around the base body 10 in a direction away from the sensing piece 11 under the action of external force. In this process, the torsion spring may be elastically deformed and generate a restoring force, and after the external force is removed, the pressing portion 21 may be reversely rotated under the restoring force so as to return to the original position. In this way, the pressing portion 21 can return automatically without manual adjustment by a user, and the usage of the detecting device 100 is simplified.

In some embodiments, the abutment 20 further comprises an adjustment 23. The adjusting portion 23 is movably connected to the pressing portion 21, and moves along the pressing portion 21 toward the seat body 10, and at least a portion of the adjusting portion 23 is located between the pressing portion 21 and the sensing element 11. It will be appreciated that a portion of the adjustment portion 23 may be located between the pressing portion 21 and the sensing element 11, and another portion of the adjustment member may be located outside the pressing portion 21 and the sensing element 11. Or the whole adjusting member is entirely located between the pressing portion 21 and the sensing member 11.

In some examples, as shown in fig. 2, the adjustment portion 23 may be a threaded screw and nut. The screw may penetrate the pressing portion 21 and be screwed with the pressing portion 21, wherein a head of the screw may be located between the pressing portion 21 and the sensing element 11, and the nut may fix the screw to the pressing portion 21 and adjust a distance of the screw moving relative to the pressing portion 21.

When the pressing part 21 is in contact with the sensor 200 to be detected and applies pressure to the sensor 200 to be detected, the sensor 200 to be detected can be pressed by the screw by reducing the interval between the screw and the sensor 200 to be detected, thereby increasing the contact area between the sensor 200 to be detected and the sensing member 11, and thus increasing the reliability of the detection data.

In other examples, the adjusting portion 23 may be entirely disposed between the pressing portion 21 and the sensing piece 11. Also, the distance between the regulating member and the sensor to be detected 200 may be reduced to press the sensor to be detected 200 so as to contact the contact area between the sensor to be detected 200 and the sensing member 11.

Therefore, when the pressing portion 21 applies pressure to the sensor 200 to be detected, and the sensor 200 to be detected and the sensing piece 11 cannot be brought into full contact, fine adjustment can be performed by the adjusting portion 23, and the sensor 200 to be detected is applied with pressure by the adjusting portion 23, so that the sensor 200 to be detected and the sensing piece 11 are fully contacted, and the reliability of detection data is improved.

In some embodiments, as shown in FIG. 2, retaining member 30 may be rotatably coupled to housing 10. For example, the locking member 30 and the base 10 may be coupled by a rotation shaft. After the sensor 200 to be detected is placed at the sensing element 11 and the abutting element 20 is limited by the locking element 30, the pressing portion 21 of the abutting element 20 can abut against the sensor 200 to be detected and exert pressure on the sensor 200 to be detected, so that the sensor 200 to be detected can be in contact with the sensing element 11.

The locking piece 30 is arranged in a rotatable mode, so that the locking piece is not only convenient to abut against the abutting piece 20 to limit the abutting piece 20, but also the probability of interference between the sensor 200 to be detected and the locking piece 30 can be reduced when the sensor 200 to be detected is taken and placed, and the sensor 200 to be detected is effectively protected.

With continued reference to fig. 2, in some embodiments, retaining member 30 further includes a resilient portion 32. One end of the elastic portion 32 may be rotatably connected to the base 10, and the other end may be connected to the limiting portion 31.

Illustratively, in the example shown in fig. 2, the locking member 30 is rotatably coupled to the housing 10 via a rotational shaft. The elastic portion 32 may be provided as a torsion spring, which may be sleeved outside the rotation shaft.

When the locking member 30 is restrained against the abutment 20 and the locking member 30 receives a reaction force from the abutment 20, the locking member 30 can be reversely rotated (e.g., rotated by 20 ° to 25 °). At this time, the elastic portion 32 generates an elastic restoring force by the reaction force. Since the elastic restoring force and the reaction force are opposite in direction, the lock member 30 can always limit the abutment member 20. Thus, the above arrangement can reduce the probability of the lock member 30 and the abutment member 20 being separated. And the elastic part 32 can also realize the automatic return of the locking piece 30.

In some examples, as shown in fig. 2, the locking member 30 is provided with a clamping groove 33, and the clamping groove 33 may form the limiting portion 31. As shown in fig. 2, the abutment portion 22 may be provided so as to protrude with respect to the pressing portion 21. When the limiting part 31 is connected with the abutting part 22, the abutting part 22 can extend into the clamping groove 33, so that the groove wall of the clamping groove 33 can be clamped with the abutting part 22, the connection stability between the limiting part 31 and the abutting part 22 can be improved, and the probability of separation of the limiting part and the abutting part under the action of external force is reduced.

In some embodiments, as shown in fig. 2 to 4, the sensing element 11 may include a sensing portion 111 and a connection portion 112. One end of the sensing part 111 may be used to support and communicate with the detection sensor 200, and the other end may be electrically connected with the connection part 112. The connection portion 112 may be used to electrically connect to an analysis device, and the connection portion 112 may be an electronic component such as a PCBA or the like disposed on a printed circuit board.

Illustratively, as shown in fig. 5, the sensing portion 111 may include a plurality of pins, and the plurality of pins are spaced to form a circle. The ends of the plurality of pins for contacting the sensor to be detected 200 may be bent and radially distributed, and the other ends of the plurality of pins may be electrically connected to the connection part 112.

When the sensor to be detected 200 is placed on the sensing portion 111, part of the pins of the sensing portion 111 may not contact with the sensor to be detected 200. And a certain pressure is applied to the sensor 200 to be detected, the sensing portion to be detected can be contacted with each pin of the sensing portion 111, so that better data acquisition can be performed on the sensor 200 to be detected. The collected data may be transmitted via connection 112 to an analysis device (e.g., a host computer) that may analyze the collected data to determine whether the detected sensor is acceptable.

Further, in some embodiments, the sensing portion 111 is an elastic member. When the sensor 200 to be detected is placed on the sensing portion 111, a certain pressure is applied to the sensor 200 to be detected, and the sensing portion 111 can deform to a certain extent, so that the probability of fracture of the sensing portion 111 is reduced, and the service life of the sensing portion 111 is prolonged.

In some embodiments, as shown in fig. 1, the base 10 is provided with a recess 12. A sensing part 111 may be provided in the recess 12 and used for placing the sensor 200 to be detected.

In detecting the sensor to be detected 200, the sensor to be detected 200 may be placed in the recess 12 of the base 10. Since the bottom of the recess 12 is provided with the sensing portion 111, the sensor 200 to be detected can be in contact with the sensing portion 111. Moreover, the groove wall of the groove 12 can play a certain limiting role on the sensor 200 to be detected, so that the groove 12 can improve the accuracy of the detection result and reduce the probability of influencing the detection result due to deviation from the original position in the detection process of the sensor 200 to be detected.

In some embodiments, the connecting portion 112 may be disposed on a side of the base 10 facing away from the abutment 20. The connection portion 112 is provided with an electrical connection portion 112, one end of the electrical connection portion 112 may be electrically connected to the sensing portion 111, and the other end may be electrically connected to the analysis device.

In other words, the connection portion 112 may be used as a supporting portion of the entire detection device 100, and the connection portion 112 may be provided with the seat 10 and other components, so as to simplify the structure of the entire detection device 100.

In addition, the embodiment of the utility model also provides a detection system 1000. Referring to fig. 6, a detection system 1000 may include a mounting platform 300 and a plurality of the detection devices 100 described above. All the detecting devices 100 can be mounted on the mounting platform 300, the sensing elements 11 of all the detecting devices 100 are electrically connected to the output end of the mounting platform 300, and the output end of the mounting platform 300 is used for electrically connecting with the analyzing device.

Illustratively, in the example shown in fig. 6, the mounting platform 300 may be provided with 20 detection devices 100. Each detection device 100 can be used to detect one sensor, that is, 20 sensors can be detected at the same time, so that the detection efficiency is improved.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
