Fig. 1 and 2 are a schematic perspective view and a bottom view of a protector according to an embodiment of the present disclosure. Fig. 3 and 4 show one possible application scenario of the protector of the disclosed embodiment.

Referring to fig. 1-4, the protector 100 includes a guard ring 110, a support structure 120, and a mounting structure. The guard ring 110 has a mounting hole, and a support structure 120 is at least partially disposed within the guard ring 110 and coupled to the guard ring 110 to support the guard ring 110 such that the guard ring 110 maintains a predetermined shape. A mounting structure is provided to support structure 120 for connection with sensor 200. After the protector 100 is connected with the sensor 200 through the mounting structure, the outer edge of the protective ring 110 protrudes out of the edge of the sensor 200, and when the sensor 200 falls, the protective ring 110 can prevent the sensor 200 from directly colliding with hard objects such as the ground, so that the sensor 200 can be protected.

The mounting structure may be any structure capable of connecting the sensor 200 and the protector 100, and may include, for example, an adhesive, a snap, a threaded structure, a socket, a magnetic attraction structure, and the like, which may be specifically selected according to the type and the use scenario of the sensor 200. The attachment of the mounting structure to the sensor 200 may be in a fixed, non-detachable form, or may be in a detachable form. In some embodiments, the mounting structure can be removably coupled to the sensor 200, thereby allowing the protector 100 to be coupled to the sensor 200 or the protector 100 to be removed from the sensor 200 as desired, which can improve flexibility of use. In one embodiment, the mounting structure includes at least one suction cup 130, and the protector 100 may be attached to the sensor 200 by suction via the suction cup 130. When the protector 100 is connected with the sensor 200, the end part of the sensor 200 is placed into the mounting hole from the first opening 111, and then the protector 100 is pressed to discharge air between the suction cup and the end face of the sensor 200, so that connection can be realized, and the installation is convenient. After the protector 100 is connected with the sensor 200 through the suction cup 130, the protector 100 can be ensured not to fall off in a certain degree of collision. When it is desired to remove the protector 100, a force may be applied to the protector 100 to separate the suction cup 130 from the surface of the sensor 200. In another embodiment, the mounting structure includes a snap that can snap into engagement with a corresponding snap groove on the sensor 200. It is understood that the specific form of the mounting structure is not limited to the above, and those skilled in the art can arrange the mounting structure in other forms as needed.

The shape of the protective ring 110 and the first opening 111 can be set as required, and the size of the first opening 111 is enough to accommodate the end of the sensor 200, so as to protect the sensor 200 well and avoid the edge or corner of the sensor 200 from colliding with a hard object directly. Alternatively, the first opening 111 matches the shape of the end of the sensor 200, for example, referring to fig. 3 and 4, the end of the sensor 200 is square, the protective ring 100 may be a hollow rectangle, and the first opening 111 may be a rectangular opening with a corresponding size. The suction cup 130 is disposed at an end of the supporting structure 120 facing the first opening 111. Therefore, when the suction cup 130 is connected to the sensor 200, the protection ring 110 can be fitted over the end of the sensor 200, so that the protector 100 can be stably connected to the sensor 200, and the protector 100 can be prevented from falling off. Of course, the first opening 111 may be sized larger than the end of the sensor 200, as desired.

The protective ring 110 may be made of a flexible material, an elastic material, or other materials capable of absorbing vibration, such as rubber, silicone, foam, etc. After the protector 100 is connected to the sensor 200, the protective ring 110 can protect the sensor 200. When the sensor 200 falls, the protection ring 110 can play a role in buffering and absorbing impact force, and the sensor 200 is prevented from being damaged due to large impact.

The support structure 120 has a certain deformation resistance in a direction perpendicular to the axis of the guard ring 110 to provide a certain support capability to the guard ring 110. The support structure 120 may be made of a rigid material or an elastic material. In one embodiment, the supporting structure 120 and the protection ring 110 may be made of the same material, such as rubber or high molecular polymer, and the supporting structure 120 and the protection ring 110 may be manufactured by molding, etc., which facilitates processing and improves the stability of the connection between the supporting structure 120 and the protection ring 110. In another embodiment, the support structure 120 may be manufactured first, and then a part of the support structure is embedded in the protective ring 110 by insert molding or the like, so that the reliability of the connection between the support structure 120 and the protective ring 110 can be improved.

In some embodiments, support structure 120 includes a center block 121 and a plurality of connecting arms 122. The inner hole of the protection ring 110 is a through hole, and the center block 121 is disposed in the protection ring 110 with a certain gap from the sidewall of the protection ring 110. The central block 121 is sized to accommodate the suction cup 130, and the suction cup 130 is disposed on the central block 121. A plurality of connecting arms 122 are spaced apart and distributed around the central block 121 for connecting the central block 121 and the guard ring 110. By providing a plurality of connecting arms 122, the protective ring 110 can be supported well, so that the protective ring 110 can maintain a certain shape, and the sensor 200 can be protected better. Meanwhile, compared with a closed structure in which the supporting structure 120 is set to shield the first opening 111, the connecting arms 122 arranged at a plurality of intervals can form a hollowed-out shape, so that the overall weight of the protector 100 is reduced, and the situation that the sensor 200 cannot be installed in place due to the rise of air pressure caused by the sealing of the inner hole of the protective ring 110 when the sensor 200 is installed in the protective ring 110 is avoided. Of course, when the first opening 111 is larger than the sensor 200, the inner hole of the guard ring 110 may be a blind hole.

The shape, extending direction and arrangement of the connecting arms 122 can be set as required. In some embodiments, the connecting arms 122 may be radially distributed outside the central block 121, and a certain included angle is formed between two adjacent connecting arms 122. Optionally, each connecting arm 122 extends from an edge of the central block 121 to a side wall of the guard ring 110. Of course, the connecting arm 122 can also extend from the middle or other position of the center block 121 to the guard ring 110. The supporting structure 120 may be integrally formed in a sheet shape, i.e., the plurality of connecting arms 122 and the central block 121 are substantially located on the same plane; the plurality of connecting arms 122 may also be disposed on different planes.

In one embodiment, the inner hole of the guard ring 110 is a polygon having a plurality of vertices. The connecting arms 122 are located at positions corresponding to the positions of the corners, and the connecting arms 122 extend from the edge of the central block 121 to the corresponding corners. The number of connecting arms 122 may be the same as the number of apex angles. For example, referring to fig. 1 and 2, the inner hole of the guard ring 110 is a rectangular hole, the center block 121 is a circular sheet, the number of the connecting arms 122 is four, and the four connecting arms 122 correspond to four corners of the rectangular hole, respectively.

In some embodiments, the width of the connecting arm 122 gradually increases from one end close to the central block 121 to one end close to the corresponding vertex angle, and the connecting arm 122 extends to two sides of the polygon on two sides of the corresponding vertex angle, so that the supporting effect on the protection ring 100 can be improved, and the protection ring 100 can be prevented from cracking from the vertex angle.

The support structure 120 can be completely received inside the first opening 111, and the protective ring 110 can protect the support structure 120 to prevent the support structure 120 from being damaged. The mounting structure may also be completely contained within the guard ring 110. For example, referring to fig. 2 and 3, the mounting structure is a suction cup 130 and is received in an inner hole of the protective ring 110, that is, the suction cup 130 does not protrude from an edge of the first opening 111, or the suction cup 130 is disposed inside the first opening 111. Therefore, the end of the sensor 200 can be better accommodated in the protection ring 110, thereby providing a good protection effect for the sensor 200.

In one possible application scenario, multiple protectors 100 may be provided to protect different portions of the sensor 200, respectively. For example, when the sensor 200 has two opposite ends, two protectors 100 may be provided to be connected to the two ends of the sensor 200, respectively. In another possible application scenario, one end of the sensor 200 is fixedly disposed, and the protector 100 can be disposed at the other end of the sensor 200 to avoid the sensor 200 colliding with a hard object.

Fig. 3 and 4 are a schematic exploded view and a schematic perspective view of a sensor assembly according to an embodiment of the present invention.

Referring to fig. 3 and 4, as one possible application of the protector in the present disclosure, an embodiment of the present disclosure further provides a sensor assembly. The sensor assembly includes a sensor 200, a base 300, and a protector 100 in at least some embodiments of the present disclosure. The base 300 is used to mount the sensor 200 at a predetermined position, and the protector 100 is coupled with the sensor 200 to protect the sensor 200.

The base 300 can be connected to any position of the sensor 200 as required, and the protector 100 is disposed on the sensor 200 at a portion not covered by the base 300. In some embodiments, the base 300 and the protector 100 may be connected to opposite ends of the sensor 200. The sensor 200 has opposite first and second ends, the first end having a first connection structure 210, the base 300 having a second connection structure 310 matching the first connection structure 210, the second connection structure 310 being connectable with the first connection structure 210 to connect the sensor 200 to the base 300. The base 300 may be disposed at a predetermined position by means of adhesion, fastening, magnetic attachment, etc., thereby disposing the sensor 200 at a predetermined position. The suction cup 130 of the protector 100 is connected to the second end of the sensor 200.

The base 300 has a connection end surface 320 opposite to the first end of the sensor 200, and the second connection structure 310 is disposed on the connection end surface 320. Optionally, an orthographic projection of the outer contour of the sensor 200 on the connecting end surface 320 is located inside the outer contour of the connecting end surface 320, that is, the outer contour of the sensor 200 does not protrude beyond the outer contour of the connecting end surface 320. Thus, when the sensor assembly is dropped as a whole, the protector 100 and the base 300 can respectively lift the sensor 200 from both ends, and the sensor 200 does not directly collide with the ground. Optionally, an orthographic projection of the outer contour of the protection ring 110 on the connecting end surface 320 is located inside the outer contour of the connecting end surface 320, that is, the protection ring 110 is smaller than the base 300, so that stability of the sensor assembly during placement can be improved, and the sensor assembly is prevented from being inclined and falling off easily due to too high center of gravity.

The first connection structure 210 and the second connection structure 310 may take any form, for example, a plug connection, a snap connection, an adhesive connection, a screw connection, etc. may be used. The first connecting structure 210 and the second connecting structure 310 may be connected in a non-detachable manner or in a detachable manner. Optionally, the first connecting structure 210 is detachably connected with the second connecting structure 310, facilitating the placement and replacement of the sensor 200.

In one embodiment, referring to fig. 3, the first connecting structure 210 is a connecting hole and the second connecting structure 310 is a connecting rod, and the connecting hole is matched with the connecting rod. When the sensor 200 is connected to the base 300, the connecting rod can be completely inserted into the connecting hole, so that the first end of the sensor 200 is in contact with the connecting end surface 320 of the base 300, and the sensor 200 can be well fixed. Alternatively, the connecting rod has an external thread and the connecting hole has a corresponding internal thread, the sensor 200 and the base 300 can be detachably connected through the threaded connection of the first connecting structure 210 and the second connecting structure 310. The threaded connection can better prevent the sensor 200 from vibrating off the base 300. In another embodiment, the first connecting structure 210 is a latch, the second connecting structure 310 is a slot corresponding to the latch, and the sensor 200 and the base 300 can be connected by latching the latch into the slot. In another embodiment, the first connecting structure 210 and the second connecting structure 310 may be adhesive layers corresponding to each other, and the sensor 200 and the base 300 may be connected by adhesion. It should be understood that the forms of the first connecting structure 210 and the second connecting structure 310 are not limited to the above, and those skilled in the art can select the forms of the first connecting structure 210 and the second connecting structure 310 according to the requirements of the specific application of the sensor assembly.

The sensor assembly of the embodiment of the disclosure can be applied to various scenes to realize corresponding sensing functions. In one possible application scenario, the sensor assembly may be applied to a vehicle performance testing system for performing performance testing on a vehicle. For example, the sensor 200 is an acceleration sensor, and acceleration can be detected by using the sensor assembly, and the sensor assembly can be applied to a vibration test of a vehicle.

The vehicle performance testing system includes one or more sensor assemblies for collecting data. It is understood that the vehicle performance testing system may further include other devices, apparatuses, elements, etc. required for performing performance testing on the vehicle, such as a data processing device for processing and analyzing data collected by the sensor 200, a communication device for transmitting and receiving signals, a test stand for performing corresponding actions on the vehicle, etc. The particular configuration of the vehicle performance testing system may be selected by one skilled in the art as required by the test.

Taking the vibration test of the vehicle as an example, the base 300 may be fixed to a predetermined position on the vehicle, such as a seat, a steering wheel, a floor, etc., by a certain manner (e.g., gluing) during the test. After the base 300 is fixed, the first connecting structure 210 of the sensor 200 may be connected to the second connecting structure 310 of the base 300, and then the protector 100 may be connected to the second end of the sensor 200. During testing, if the sensor assembly falls off, the protector 100 and the base 300 can both protect the sensor 200, and direct collision between the sensor 200 and hard objects such as the ground is avoided.

It will be readily understood by those skilled in the art that the assembly process of the sensor assembly need not be performed entirely in accordance with the above steps, and that the order of installation may be adjusted as desired. For example, the sensor 200 may be connected to the base 300, and then the base 300 may be fixed to the vehicle.

The embodiment of the utility model provides a protector, a sensor assembly applying the protector and a vehicle performance testing system applying the sensor assembly. By connecting the suction cup to the sensor, the protector can be arranged on the sensor. Therefore, the protector can protect the sensor, the sensor is effectively prevented from being directly collided with a hard object to be damaged, the sensing accuracy and the service life of the sensor can be guaranteed, and the accuracy of a vehicle performance test result is guaranteed.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
