The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0021] The following is combined with Figure 1-3 The utility model is described in further detail.

[0022] The utility model embodiment discloses a detection device for the EPP buffer block at the lower part of the front bumper. Figure 1-Figure 3 The detection device for the EPP buffer block at the lower part of the front bumper includes a bottom plate 1, on which a position detection mechanism 2 for detecting the size of the buffer block is arranged, and the position detection mechanism 2 includes a measuring template 21 arranged on the bottom plate 1 and two positioning columns 22 arranged on one side of the measuring template 21. The EPP buffer block is placed on the bottom plate 1 and leans against the side of the measuring template 21 on which the positioning columns 22 are arranged. The top of the measuring template 21 is flush with the top of the EPP buffer block. The positioning columns 22 pass through the reserved holes on the EPP buffer block. The two positioning columns 22 are adjustable in horizontal position on the measuring template 21. According to the two reserved holes on the EPP buffer block, The spacing between the two positioning posts 22 is adjusted by moving the two positioning posts 22. The prepared EPP buffer block is placed on the base plate 1 and moved toward the measuring template 21 to see whether the two positioning posts 22 can be inserted into the two reserved holes. If they can be inserted, the size of the reserved holes meets the requirements, otherwise, they do not meet the requirements. The spacing between the two positioning posts 22 can be changed according to the spacing between the two reserved holes, and the applicability is better. The EPP buffer block is placed close to the measuring template 21 to see whether the EPP buffer block 21 and the top of the measuring template are flush. If they are flush, they meet the requirements, and if there is a height difference, they do not meet the requirements. It is more convenient to use and the measurement is more accurate.

[0023] In this embodiment, a movable groove 211 for moving the positioning column 22 is provided in the horizontal direction on the measuring template 21. One end of the positioning column 22 is inserted into the movable groove 211 and can be driven to move along the movable groove 211. By moving the two positioning columns 22 in the movable groove 211, the distance between the two positioning columns 22 can be adjusted.

[0024] In this embodiment, an adjusting screw 3 is arranged in the measuring template 21 so as to rotate in the horizontal direction. The adjusting screw 3 is provided with external threads in opposite directions from the middle to both ends. The ends of the two positioning columns 22 are respectively threadedly mounted on the two ends of the adjusting screw 3. A collar is arranged on the ends of the two positioning columns 22. An internal thread is arranged on the inner ring of the collar and can be used in conjunction with the external thread on the adjusting screw 3. One end of the adjusting screw 3 extends out of the measuring template 21. When the adjusting screw 3 is rotated, the two positioning columns 22 move in opposite directions. By rotating the adjusting screw 3, the two positioning columns 22 can move in opposite directions, so that the distance adjustment between the two positioning columns 22 is more convenient.

[0025] In this embodiment, the measuring template 21 is provided with scale lines on one side of the movable groove 211. By adjusting the positioning column 22 and the reverse direction according to the standard data of the spacing between the two reserved holes, the scale lines can be referred to when moving the positioning column 22, so that the spacing adjustment of the positioning column 22 is more accurate.

[0026] In this embodiment, a knob 31 is provided at one end of the adjusting screw 3 outside the measuring template 21 , and the adjusting screw 3 is driven to rotate by rotating the knob 31 .

[0027] In this embodiment, the position detection mechanism 2 also includes a positioning plate 23 arranged on the top of the measuring template 21, and the positioning plate 23 is hinged to the top side of the measuring template 21 away from the positioning column 22. The positioning plate 23 can be flipped on the measuring template 21 and pressed on the top of the measuring template 21 and the EPP buffer block. After the EPP buffer block is attached to the measuring template 21, the positioning plate 23 is flipped to press the measuring template 21 and the top of the EPP buffer block. When measuring, when the positioning plate 23 can be pressed on the measuring template 21 and the EPP buffer block at the same time in a horizontal state, the EPP buffer block meets the requirements, otherwise it does not meet the requirements.

[0028] In this embodiment, it also includes a pressure detection mechanism 4 arranged on the base plate 1, and the pressure detection mechanism 4 includes a measuring rod 41, a pressure sensor 42 arranged at the end of the measuring rod 41, and a pressure display 43 connected to the signal of the pressure sensor 42. The measuring rod 41 can be driven to move toward the EPP buffer block and make the pressure sensor 42 abut against the EPP buffer block. The pressure display 43 is used to display the value of the pressure measured by the pressure sensor 42. The measuring rod 41 is moved toward the EPP buffer block to make the pressure sensor 42 abut against the EPP buffer block and apply pressure to it. The pressure data measured by the pressure sensor 42 is transmitted to the pressure display 43. When the actual pressure on the pressure display 43 reaches the pressure-bearing standard of the buffer block, the EPP buffer block is not damaged and meets the requirements, otherwise it does not meet the requirements.

[0029] In this embodiment, a mounting platform 11 for mounting a measuring rod 41 is provided on the base plate 1. The measuring rod 41 passes through the mounting platform 11 in a horizontal direction. A rotatable adjusting tube 12 is provided on one side of the mounting platform 11. The measuring rod 41 passes through the adjusting tube 12 and is threadedly engaged with the adjusting tube 12. By rotating the adjusting tube 12, the measuring rod 41 can be moved toward the EPP buffer block on the mounting platform 11, which is more convenient to use.

[0030] In this embodiment, a pressure plate 44 is provided at one end of the measuring rod 41 facing the measuring template 21, and the pressure plate 44 is installed on the pressure sensor 42. The pressure plate 44 is used to contact the EPP buffer block. The pressure sensor 42 is contacted with the EPP buffer block by the pressure plate 44 instead of the pressure sensor 42, so that the contact area between the pressure sensor 42 and the EPP buffer block can be increased, and the possibility of damage to the EPP buffer block due to the small contact area with the pressure sensor 42 is reduced, so that the measurement data is more accurate.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
