The first embodiment of the utility model provides a mounting bracket for a flexible thin film sensing piece, which is used for being fixed on an object to be measured and mounting the flexible thin film sensing piece so as to keep a specific state between the flexible thin film sensing piece and the object to be measured.

Referring to fig. 1 to 6, specifically, the mounting bracket 1 includes a bracket body 11 and at least one limiting block 12, where the bracket body 11 is provided with an avoidance hole 111 for accommodating an object to be tested and at least one limiting through hole 112. The limiting block 12 and the avoiding hole 111 are respectively arranged on two adjacent sides of the bracket body 11, the limiting through hole 112 is provided with two openings 1121 which are mutually communicated, one opening 1121 and the avoiding hole 111 are arranged on the same side, and the other opening 1121 and the limiting block 12 are arranged on the same side.

It will be appreciated that since the limiting through hole 112 has two openings 1121 communicating with each other, the flexible thin film sensor chip can pass through the opening 1121 of one side from the opening 1121 of the other side. Because one of the openings 1121 and the avoidance hole 111 are disposed on the same side, and the other opening 1121 and the stopper 12 are disposed on the same side, when the flexible film sensing sheet (shown in fig. 2 and fig. 4 a) is fixed on the mounting bracket 1, one end of the flexible film sensing sheet may be fixed on the side of the avoidance hole 111 away from the limiting through hole 112, and the other end of the flexible film sensing sheet passes through the avoidance hole 111 and is fixed on the side provided with the stopper 12. It can be appreciated that the movement direction of the flexible thin film sensing piece can be limited by the limiting through hole 112, so that the flexible thin film sensing piece can only move along the direction of the limiting through hole 112. According to the embodiment of the utility model, the limiting block 12 is arranged on the adjacent side of the side, provided with the avoidance hole 111, of the support body 11, and the shape and the deformation direction of the flexible thin film sensing piece can be limited by matching the limiting block 12 with the limiting through hole 112, so that the flexible thin film sensing piece is prevented from being randomly rocked due to external force, and the flexible thin film sensing piece and an object to be detected can be kept in a relatively stable state.

The shape of the avoiding hole 111 is not particularly limited in the embodiment of the present utility model, and the shape and size of the avoiding hole 111 may be designed according to the shape of the object to be measured. The avoiding holes 111 may be square through holes, the avoiding holes 111 may be circular through holes, and the avoiding holes 111 may be racetrack through holes.

The shape of the bracket body 11 is not particularly limited, and the shape of the bracket body 11 can be matched and designed according to the shape of an object to be detected. As one embodiment, the bracket body 11 is L-shaped; as another embodiment, the bracket body 11 is U-like shaped.

Referring to fig. 3 and 4, as an embodiment, the bracket body 11 has an L shape. Specifically, the bracket body 11 has a first body 113 and a second body 114 bent along one end of the first body 113, and the limiting through hole 112 is disposed at a connection position between the first body 113 and the second body 114. The first body 113 is provided with a first mounting region 1131 for connecting with the flexible thin film sensor sheet, and the avoidance hole 111 is provided on the first body 113 and between the first mounting region 1131 and the limiting through hole 112. The second body 114 is provided with a second mounting region 1141 for connection with the flexible film sensor chip, and the stopper 12 is disposed on the second body 114 and between the second mounting region 1141 and the stopper through hole 112.

It can be appreciated that the first mounting region 1131 and the second mounting region 1141 are regions for fixedly connecting with the flexible film sensor chip, and the flexible film sensor chip can be fixed in the first mounting region 1131 and the second mounting region 1141 by bonding. When the flexible thin film sensor sheet (shown in a of fig. 4) is fixed on the mounting bracket 1, one end of the flexible thin film sensor sheet is fixed on the first mounting region 1131, and the other end is fixed on the second mounting region 1141 after passing through the limiting through hole 112. Because the avoiding hole 111 is disposed between the first mounting region 1131 and the limiting through hole 112, and the limiting block 12 is disposed between the second mounting region 1141 and the limiting through hole 112, the flexible film sensing sheet after fixing will cover the limiting block 12 and the avoiding hole 111. From the above, the movable range of the flexible film sensor chip can be limited by the limit block 12 cooperating with the limit through hole 112. The avoidance hole 111 is used for accommodating an object to be measured, and the flexible film sensing sheet covers the object to be measured while covering the avoidance hole 111. In this way, the mounting bracket 1 can enable the flexible film sensing sheet to be arranged corresponding to the object to be detected and enable the flexible film sensing sheet to keep a specific relative position with the object to be detected.

Referring to fig. 1 and 2, as another embodiment, the bracket body 11 is U-shaped. Specifically, the mounting bracket 1 is provided with two limiting blocks 12, the bracket body 11 is provided with a third body 115, and a fourth body 116 and a fifth body 117 which are respectively bent along two opposite ends of the third body 115, and the avoidance hole 111 is arranged on the third body 115. The bracket body 11 is provided with two limiting through holes 112, and the two limiting through holes 112 are respectively arranged at the joint of the third body 115 and the fourth body 116 and the joint of the third body 115 and the fifth body 117. The fourth body 116 is provided with a third mounting region 1161 for connection with the flexible thin film sensor chip, and the fifth body 117 is provided with a fourth mounting region 1171 for connection with the flexible thin film sensor chip. One stopper 12 is disposed on the fourth body 116 between the third mounting region 1161 and the stopper through hole 112, and the other stopper 12 is disposed on the fifth body 117 between the fourth mounting region 1171 and the stopper through hole 112.

It is understood that the third mounting area 1161 and the fourth mounting area 1171 are areas for fixedly connecting with the flexible film sensor chip, and the flexible film sensor chip may be fixed on the third mounting area 1161 and the fourth mounting area 1171 by bonding. When the flexible film sensor chip (shown in fig. 2 a) is fixed on the mounting bracket 1, one end of the flexible film sensor chip is fixed on the third mounting area 1161, and the other end sequentially passes through the two limiting through holes 112 and then is fixed on the fourth mounting area 1171. Because the avoiding holes 111 are formed in the third body 115, the two limiting blocks 12 are respectively formed between the third mounting area 1161 and the limiting through hole 112 and between the fourth mounting area 1171 and the limiting through hole 112, and thus the flexible film sensing sheet after fixing is completed can cover the two limiting blocks 12 and the avoiding holes 111.

Referring to fig. 1 and 3, further, the stopper 12 has a surface (shown in b of fig. 1 and 3) contacting the flexible thin film sensor chip, and the surface is an arc surface. It can be understood that the limiting block 12 is arranged on the bracket body 11, on one hand, the shape of the flexible film sensing piece is limited by the limiting block 12, and on the other hand, the friction force born by the flexible film sensing piece is increased by the contact between the flexible film sensing piece and the limiting block 12 so as to counteract the influence of gravity on the flexible film sensing piece. In this embodiment, the surface of the stopper 12, which contacts with the flexible thin film sensing sheet, is set to be an arc surface, and the arc surface can enlarge the contact area between the flexible thin film sensing sheet and the stopper 12, so as to enlarge the friction force borne by the flexible thin film sensing sheet, and further reduce the influence of gravity on the flexible thin film sensing sheet. It can be appreciated that the arc surface is a curved surface with smooth transition and no sharp corner, so that in the process that the flexible film sensing sheet contacts the limiting block 12, the arc surface can make the stress of the flexible film sensing sheet approximately uniform, thereby avoiding the generation of stress concentration.

The shape of the limiting block 12 is not particularly limited in the embodiment of the present utility model, and the limiting block 12 may be a curved surface as long as it protrudes from the surface of the bracket body 11 and contacts the flexible thin film sensor chip. As a preferred embodiment, the stopper 12 is a semi-cylinder protruding from the surface of the bracket body 11.

The utility model does not limit the mode that the limiting block 12 is fixed on the bracket body 11, the limiting block 12 can be fixed on the bracket body 11 in a welding mode, the limiting block 12 can also be fixed on the bracket body 11 in an adhesive mode, and the limiting block 12 can also be integrally formed with the bracket body 11.

The utility model does not limit the materials of the limiting block 12 and the bracket body 11, the limiting block 12 and the bracket body 11 can be plastic parts, and the limiting block 12 and the bracket body 11 can be steel parts.

The connection mode between the mounting bracket 1 and the object to be measured is not particularly limited. The mounting bracket 1 can be fixed on an object to be measured in an adhesive mode, the mounting bracket 1 can also be fixed on the object to be measured through a bolt fastener, and the mounting bracket 1 can also be fixed on the object to be measured in a clamping mode.

Referring to fig. 6, as one preferred embodiment, the mounting bracket 1 is fastened to the object to be measured by means of a clamping connection. Specifically, the mounting bracket 1 is further provided with an elastic clamping member 13, the elastic clamping member 13 is at least disposed at two opposite sides of the avoidance hole 111 and is fixedly connected with the bracket body 11, and the opposite elastic clamping members 13 form a clamping space.

When the mounting bracket 1 is sleeved on the object to be measured, the object to be measured presses the elastic clamping members 13 arranged at two opposite sides of the avoiding hole 111 to pass through the clamping space. When the object to be measured passes through the clamping space, the object to be measured tends to squeeze the elastic clamping piece 13, at this time, the elastic clamping piece 13 changes the size of the clamping space through elastic deformation so that the object to be measured can pass through the clamping space, and the elastic clamping piece 13 with elastic deformation acts on an extrusion force to the object to be measured so that the friction force between the elastic clamping piece 13 and the object to be measured is increased. It will be appreciated that a large friction force can cause the mounting bracket 1 to be clamped and fixed on the object to be measured.

With continued reference to fig. 6, as an embodiment, elastic clamping members 13 are disposed around the inner circumference of the avoidance hole 111. For example, when the inner contour of the escape hole 111 is quadrangular, elastic clamping members 13 are disposed around the escape hole 111. When the inner contour of the escape hole 111 is circular, elastic clamping members 13 are provided in the circumferential direction of the escape hole 111.

It can be appreciated that the elastic clamping member 13 is disposed along a circumference of the inner side of the avoidance hole 111, so that the friction force between the elastic clamping member 13 and the object to be measured can be further increased, and the mounting bracket 1 can be more firmly clamped and fixed on the object to be measured.

The utility model does not limit the manner of fixing the elastic clamping member 13 on the bracket body 11, the elastic clamping member 13 can be fixed on the bracket body 11 by bonding, and the elastic clamping member 13 can also be fixed on the bracket body 11 by clamping. As a preferred embodiment, the elastic clamping member 13 of the present utility model is fixed to the bracket body 11 by means of adhesion. It will be appreciated that the elastic clamping member 13 is fixed to the bracket body 11 by means of adhesion so that the installation of the elastic clamping member 13 is easier and more convenient.

The type of the elastic clamping member 13 is not particularly limited in the embodiment of the present utility model, as long as the mounting bracket 1 can be clamped on the object to be measured by elastic deformation of the elastic clamping member 13.

Preferably, the elastic clamping member 13 is silica gel or foam. It can be understood that the silica gel and the foam have good elasticity, and can generate certain elastic deformation when being extruded by the object to be tested so that the object to be tested can pass through the clamping space, and the friction force acting on the object to be tested can be increased through the deformed silica gel or foam, so that the mounting bracket 1 can be clamped on the object to be tested more stably.

The foregoing is merely an alternative embodiment of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the scope of the claims of the present application.
