[0028] The mounting mechanism includes a protective housing 301 fixedly connected to the outer surface of the distance measuring sensor 2, and a stopper 305 movably arranged on the outer side wall of the telescopic door body 1 for fixing the protective housing 301;

[0029] The protection mechanism includes a connection spring 401 fixedly connected to the inner wall of the telescopic door body 1 , and a heat-conducting block 402 fixedly connected to the end surface of the connection spring 401 for transferring heat to the protection shell 301 .

[0030] The installation mechanism also includes an installation groove opened on the side wall of the telescopic door body 1, a connecting block 302 fixedly connected to the bottom of the protective shell 301, and a driving spring 303 fixedly connected to the inner wall of the installation groove, wherein when the connecting block 302 is fully retracted into the installation groove, the driving spring 303 is in a compressed state.

[0031] The mounting mechanism also includes a knob 304 rotatably connected to the outer side wall of the telescopic door body 1;

[0032] The end face of the block 305 is fixedly connected to the outer side wall of the knob 304, and the outer surface of the block 305 fits against the outer surface of the telescopic door body 1. By rotating the knob 304, the block 305 is driven to abut against the outer surface of the connecting block 302, thereby preliminarily fixing the protective shell 301 and the ranging sensor 2 inside the mounting groove.

[0033] The installation mechanism also includes a threaded hole opened on the top of the telescopic door body 1, and a fixing bolt 306 threadedly connected to the threaded hole, wherein a threaded groove is opened on the top of the protective shell 301, and the threaded hole is connected to the inside of the installation groove. By rotating the fixing bolt 306, it is connected to the threaded hole and the threaded groove, so as to further fix the protective shell 301.

[0034] The distance measuring sensor 2 is inserted into the interior of the protective housing 301, and then the protective housing 301 is inserted into the installation slot until the connecting block 302 is completely retracted into the interior of the installation slot. At this time, the driving spring 303 is in a compressed state, and then the knob 304 is turned to drive the stopper 305 to abut against the outer surface of the connecting block 302, so that the protective housing 301 and the distance measuring sensor 2 are initially fixed inside the installation slot, and then the fixing bolt 306 is turned to connect it with the threaded hole and threaded slot, so as to further fix the protective housing 301;

[0035] When the distance sensor 2 needs to be replaced, the fixing bolt 306 is removed and the knob 304 drives the stopper 305 to separate from the connecting block 302. At this time, the protective shell 301 will be partially pushed out of the installation groove under the action of the driving spring 303, thereby facilitating the removal of the distance sensor 2.

[0036] Embodiment 2: Figure 1-5 As shown, an electric telescopic door anti-collision mechanism includes a telescopic door body 1, and a distance sensor 2 arranged inside the telescopic door body 1, and also includes a mounting mechanism and a protective mechanism connected to the telescopic door body 1;

[0037] The mounting mechanism includes a protective housing 301 fixedly connected to the outer surface of the distance measuring sensor 2, and a stopper 305 movably arranged on the outer side wall of the telescopic door body 1 for fixing the protective housing 301;

[0038] The protection mechanism includes a connection spring 401 fixedly connected to the inner wall of the telescopic door body 1 , and a heat-conducting block 402 fixedly connected to the end surface of the connection spring 401 for transferring heat to the protection shell 301 .

[0039] The protection mechanism also includes a storage groove provided on the top wall of the installation groove, a through hole provided on the top of the telescopic door body 1, and a heat dissipation rod 403 fixedly connected to the top of the heat conducting block 402;

[0040] The top of the connecting spring 401 is fixedly connected to the inner top wall of the storage groove, wherein the heat conductive block 402 extends to the inside of the mounting groove under the action of the connecting spring 401, wherein the bottom edge line of the heat conductive block 402 is rounded, so that when the protective shell 301 is plugged into the mounting groove, it is convenient to push the heat conductive block 402 upward, wherein the heat dissipation rod 403 extends to the outer surface of the telescopic door body 1 through the through hole.

[0041] The protection mechanism also includes a spring groove opened on the inner wall of the installation groove, an electromagnet 405 embedded in the spring groove, a reset spring 406 fixedly connected to the bottom of the spring groove, and a locking block 407 fixedly connected to the end face of the reset spring 406, wherein the locking block 407 is made of ferromagnetic material.

[0042] The protective mechanism also includes a protective glass 404 engaged at the opening of the installation groove, a locking groove opened on the outer wall of the protective glass 404, a transmission spring 408 fixedly connected to the bottom of the locking groove, a limiting rod 409 fixedly connected to the end face of the transmission spring 408, a circular groove opened at the open end of the protective shell 301, a pushing spring 4010 fixedly connected to the bottom of the circular groove, and a pushing block 4011 fixedly connected to the end face of the pushing spring 4010, wherein the inner diameter of the locking groove is equal to the outer diameter of the locking block 407, and the protective shell 301 is made of metal copper.

[0043] When the protective housing 301 is inserted into the mounting slot, the heat conducting block 402 is pushed upward, so that the connecting spring 401 is in a compressed state, and the heat dissipation rod 403 extends to the outer surface of the telescopic door body 1 through the through hole. At this time, the heat conducting block 402 is tightly fitted with the protective housing 301 under the action of the connecting spring 401, and the heat generated by the ranging sensor 2 is transferred to the heat dissipation rod 403, thereby dissipating the heat of the ranging sensor 2;

[0044] Then, the protective glass 404 is engaged with the opening of the installation groove and abutted against the end face of the protective housing 301. At this time, the push block 4011 is completely retracted into the circular groove, and the push spring 4010 is in a compressed state. Then, the electromagnet 405 is powered off. At this time, the locking block 407 is inserted into the locking groove under the action of the reset spring 406 to fix the protective glass 404. Then, the distance sensor 2 can be used to detect people or vehicles to prevent collisions.

[0045] When the protective glass 404 needs to be replaced, the electromagnet 405 is energized to absorb the locking block 407, disengage it from the locking groove, and compress the reset spring 406. At this time, the limit rod 409 will be inserted into the spring groove under the action of the transmission spring 408, and the push spring 4010 will push the push block 4011 out of the circular groove, thereby driving the protective glass 404 to rotate and preventing the protective glass 404 from falling directly. Thereafter, the protective glass 404 can be replaced by pulling it.
