Detailed Description

In order to assist those skilled in the art in precisely understanding the subject matter claimed herein, a detailed description of the utility model is provided below in connection with the accompanying drawings.

Fig. 1 is a schematic view of an embodiment of a measuring device according to the present utility model. The measuring device comprises a base 10, a measuring part 20 and a positioning mechanism 30. The base 10 carries the measuring portion 20 above it and the positioning mechanism 30 below it. The base 10 includes a first support 11 at the bottom and a second support 13 disposed opposite to the first support 11, and the positioning mechanism 30 is disposed substantially in the space occupied by the first support 11 and the second support 13. Details of the positioning mechanism 30 will be described below.

The base 10 has two directions, a proximal end 16 and a distal end 17, the proximal end 16 being proximal to the first support 11 and the distal end 17 being distal to the first support 11. The distal end 17 is also a measurement end, and the in-door gap is measured at the distal end 17.

The positioning mechanism 30 is used to fix a measuring position of the measuring device of the present utility model relative to the vehicle door. The measurement location may be one or more specified points on the vehicle door. In one embodiment, the measurement locations may be one or more locations on a door opening perimeter of the vehicle door. The positioning mechanism 30 comprises an openable and closable clamping space 40 and a releasable driving tool 50. Fig. 1 shows the measuring device in a non-measuring state, fig. 3 shows the measuring device in a measuring state, the clamping space 40 being visible in fig. 3. The clamping space 40 is configured to open under drive control of the drive tool 50 to clamp a corresponding portion 82 of the vehicle door in the measurement position in the clamping space 40 (as shown in fig. 3) and to close when the drive tool 50 is released (as shown in fig. 1). Here, the "closing" of the holding space 40 may be a case where there is no space, a case where there is a space smaller than the space volume in the open state, or a case where the space volume is insufficient to hold the door, or a case where the positioning mechanism is in the initial state when no measurement is performed.

The clamping space 40 is opened by the driving tool 50 to reserve a gap in which the corresponding portion 82 of the door in the measuring position is clamped. Once the drive tool 50 is released, the clamping space 40 is closed when the clamping space 40 is "empty". Therefore, compared with the existing similar measuring device for gap measurement, the measuring device is very convenient for clamping the corresponding part of the vehicle door, and can finish clamping only by one action. It is well understood that the unclamping is only repeated by one and the same action.

As shown in fig. 1, the base 10 has an opening 12 at a distal end 17, and the base 10 is provided with a reference surface 14 in the opening 12, the reference surface 14 providing a measurement reference for the measurement portion 20. The measuring section 20 includes a measuring scale 22 and a probe 24 connected to each other. The probe 24 is disposed at the distal end 17 and is movable. When the probe 24 is moved into contact with the reference surface 14, the state of the measuring scale 22 at this time may be set to "zero". Such a structural arrangement facilitates calibration of the measurement portion. Before a new measurement is made, the measurement scale 22 can be zeroed by simply moving the probe 24 into contact with the datum surface 14. In one embodiment, the measuring scale 22 is an electronic digital caliper with unit settings and conversions and can display the measured value for convenient reading.

Fig. 2 shows a cross-sectional view of the measuring device, the positioning mechanism being more clearly shown in fig. 2. The positioning mechanism 30 is mounted on the first support 11 and further comprises a moving part 60, which moving part 60 is movable relative to the second support 13, whereby part of the moving part 60 and the second support 13 together define a clamping space 40, which is indicated in the figure by a dashed arrow.

The positioning mechanism 30 further includes a bearing 32 for supporting the moving portion 60. The bearing 32 passes through the inner hole 18 of the first holder 11 to be fixed with the first holder 11, and the portion of the inner hole 18 exposed forms end faces on both ends of the bearing 32. The moving portion 60 includes a shaft 62 and a press block 64 provided on a distal end of the shaft 62 (i.e., an end remote from the first holder 11). Shaft 62 moves within bearing 32 to move ram 64 toward and away from second support 13. As can be seen from fig. 2, the number of bearings and shafts is two.

A force restoring element 70 is also provided on the shaft 62 between one end face of the bearing 32 and the pressure piece 64. In the illustrated embodiment, the force restoring element 70 is a resilient device, such as a spring 72. The number of springs corresponds to the number of shafts. Spring 72 is mounted in compression between an end face of bearing 32 and press block 64. The end face of the bearing 32 is a fixed end and the press block 64 is a free end. The restoring force of the spring 72 abuts the pressing block 64 toward the second support 13 to close the clamping space 40. When the reverse driving force overcomes the restoring force, the pressing block 64 moves away from the second support 13, thereby opening the clamping space 40.

A stop 34 is provided on the proximal end of the shaft 62 (i.e., the end proximal to the first abutment 11). The driving tool 50 is configured to trigger the stopper 34 to move against the restoring force of the spring 72, thereby driving the shaft 62 and the pressing block 64 to move to open the clamping space 40. The spring 72 continues to be compressed in this case. In the illustrated embodiment, the driving tool 50 is a wrench 52 rotatably mounted on the first support 11. The wrench 52 has a contact 54, and during rotation of the wrench 52, the contact 54 pushes the stopper 34, thereby causing movement of the entire moving portion 60. The wrench 52 is manually operated by an operator. Once the operator releases the wrench 52, the restoring force of the spring 72 causes the entire moving portion 60 to move in the reverse direction. This restoring force can provide a reliable and appropriate clamping force when there is a clamped door portion within the clamping space 40.

The measuring process of the measuring device is described below in connection with fig. 3.

First, the measuring scale 22 is set to zero. The probe 24 is pushed in the direction of the datum surface (not shown) until the probe 24 contacts the datum surface, at which point the measuring scale 22 is zeroed. The probe 24 is then pulled distally a distance.

Next, the measuring device is clamped to the flange 80 of the door opening. The trigger 52 is turned to trigger the stop 34 to move against the restoring force of the spring 72. The stopper 34 moves the shaft 62 and the pressing block 64 away from the second support 13. The clamping space 40 between the press block 64 and the second support 13 is thereby opened. A corresponding portion 82 of the door on the flange 80 is clamped in the clamping space 40. Releasing the wrench 52, the restoring force of the spring 72 will abut the corresponding portion 82 of the door towards the second abutment 13, thereby providing a suitable clamping force.

Next, the door 84 is closed, the door 84 hits the probe 24 during closing, and as the door 84 continues to move, the probe 24 is pushed back in reverse until the door 84 closes, and the probe 24 stops moving. The value displayed on the measuring scale 22 at this time is the inner clearance measurement value of the vehicle door.

The above measurement process may be repeated at other locations of the flange of the door opening to obtain more in-door gap measurements.

While specific embodiments of the utility model have been shown and described in detail to illustrate the principles of the utility model, it will be understood that the utility model may be embodied otherwise without departing from such principles.
