[0065] The second bracket 132 includes two oppositely arranged flat plates with a certain distance between them. The width of the distance is greater than the thickness of the first bracket 131, so that when the risk avoidance device 1 is in the initial state, the first bracket 131 can be accommodated inside the second bracket 132 to reduce the overall volume.

[0066] In this application, the risk avoidance device 1 has two states:

[0067] 1) Initial state: When the avoidance device 1 is in the initial state, the single first bracket 131, the single second bracket 132 and the fixing rod 16 in the middle are parallel to each other, the second fixing seat 14 is limited to the middle part of the fixing rod 16, and the first return spring 185 is in a compressed state.

[0068] 2) Working state. When the avoidance device 1 is in working state, the single first bracket 131, the single second bracket 132 and the fixed rod 16 in the middle form a right triangle shape.

A button cover 10 is provided on the outer side of the top end of the thrust rod 1183. One end of the second return spring 181 abuts against the inner top wall of the button cover 10, and the other end abuts against the inner side of a fixing groove 1831 opened at the top end of the thrust rod 1183. At least two guide portions cooperating with the sliding portion 182 are provided on the inner side wall of the button cover 10. The guide portion can drive the sliding portion 182 to move up and down and synchronously drive the thrust rod 1183 to move up and down during the up and down movement of the button cover 10.

[0071] Among them, the guide part includes a first guide part 101 and a second guide part 102 in a sloped shape, the first guide part 101 has a first guide surface 1011, the second guide part 102 has a second guide surface 1021, the first guide part 101 and the second guide part 102 have the same structure but opposite directions, and the space between the two is a parallelogram shape.

[0072] The fixing rod 16 is also provided with a support seat 11 located below the button cover 10. The button cover 10 can slide up and down along the outer wall of the support seat 11, and the support seat 11 is provided with a protrusion that can limit the highest position of the button cover 10, so that the second return spring 181 can keep the button cover 10 in the highest position without being bounced off when pushing it.

[0073] The push rod 1183 passes through the center of the support seat 11 and extends to the inner area of ​​the button cover 10 .

[0074] A first support sleeve 17 is fixedly provided on the outer periphery of the fixing rod 16 , and the support seat 11 is located above the first support sleeve 17 ; the first support sleeve 17 includes a first sleeve body 171 and a first slot 172 opened in the middle of the first sleeve body 171 .

[0075] Similarly, a second support sleeve 19 is disposed at the bottom end of the fixing rod 16 . The second support sleeve 19 includes a second sleeve body 191 and a second slot 192 formed in the middle of the second sleeve body 191 .

[0076] like Fig.10 and Fig.13 As shown, the sliding portion 182 includes a first sliding section 1821, a second sliding section 1822 and a connecting section 1823 connecting the first sliding section 1821 and the second sliding section 1822, the first sliding section 1821 has a first contact surface 1821a adapted to the first guide surface 1011, and the second sliding section 1822 has a second contact surface 1822a adapted to the second guide surface 1021.

The sliding part 182 abuts against the sliding channel through the third contact surface 1823a and the fourth contact surface 1824b, and can slide along the extension direction of the sliding channel to drive the thrust rod 1183 to move in the vertical direction.

[0078] like Fig.11 and Fig.12 As shown, the clamping assembly includes a clamping block 184, a limit plate 187 arranged at the upper and lower ends of the clamping block 184, and a third return spring 186 arranged between the inner wall of the fixed rod 16 and the limit plate 187. The third return spring 186 is sleeved on the outside of the guide rod 188, and the guide rod 188 passes through the limit plate 187, so that the clamping block 184 can move along the axial direction perpendicular to the force rod 189 under the action of the force rod 189 and can be reset to the initial position under the action of the third return spring 186 after the force rod 189 is withdrawn.

[0079] The outer wall of the fixing rod 16 has at least two openings, and the block 184 can extend to the outside of the fixing rod 16 to limit the displacement of the second fixing seat 14 .

[0080] Continue to refer to Fig.11 and Fig.12 The end of the block 184 close to the center of the fixed rod 16 has at least a first inclined surface, and the end of the block 184 away from the center of the fixed rod 16 has a second inclined surface; the second inclined surface is used to abut against the second inclined surface when the second fixed seat 14 moves from the lower part of the fixed rod 16 to the middle part of the fixed rod 16 and move it toward the axial direction of the fixed rod 16, so that the avoidance device 1 is converted from the working state to the initial state.

[0081] The bottom of the force applying rod 189 has a first force applying surface 1891 and a second force applying surface 1892 which smoothly transitions to the first force applying surface 1891 .

[0082] The first force-applying surface 1891 can abut against the first inclined surface and drive the block 184 to move along the axial direction perpendicular to the force-applying rod 189 , so as to limit the second fixing seat 14 when the block 184 extends to the outside of the fixing rod 16 , thereby placing the avoidance device 1 in an initial state.

[0083] The first end of the clamping block 184 close to the center of the fixing rod 16 has a first inclined surface and a first plane. The first plane is located below the first inclined surface and is smoothly connected to the first inclined surface.

[0084] The first force applying surface 1891 is located at the end of the force applying rod 189 , and the second force applying surface 1892 is located above the first force applying surface 1891 .

[0085] The projected length of the first inclined surface on the horizontal plane is greater than the projected length of the first force applying surface 1891 on the horizontal plane.

[0086] When the avoidance device 1 is in the initial state, the second fixing seat 14 is located in the middle of the fixing rod 16 , the second force application surface 1892 of the force application rod 189 abuts against the first plane, and the block 184 is at least partially located outside the fixing rod 16 to limit the displacement of the second fixing seat 14 .

[0087] When the avoidance device 1 is in working state, the second fixing seat 14 is located at the lower part of the fixing rod 16, the second force application surface 1892 of the force application rod 189 abuts against the first plane, and the block 184 is at least partially located outside the fixing rod 16 but does not limit the displacement of the second fixing seat 14.

[0088] The third return spring 186 is in a compressed state when the avoidance device 1 is in an initial state or a working state.

[0089] A flexible reflective sheet 15 is provided between adjacent first brackets 131 . The reflective sheet 15 is in a rolled-up state when the risk avoidance device 1 is in an initial state, and is in an unfolded state when the risk avoidance device 1 is in a working state.

[0090] In the present application, the hazard avoidance device 1 is placed at the bottom of the vehicle 2 , and a receiving cavity 202 is provided at the bottom of the vehicle 2 , and a power unit 203 , a rotating rod 204 and a supporting plate 205 are provided inside the receiving cavity 202 .

[0091] The rotating rod 204 and the supporting plate 205 are used to support and limit the position of the risk avoidance device 1, and the upper end of the risk avoidance device 1 is closest to the ground.

[0092] When the power unit rotates, the rotating rod 204 is driven to rotate, so that the escape device 1 can be released from the position limit.

[0093] The vehicle 2 further includes a control system, which controls the rotation of the power unit 203 via an operation button 201 disposed inside the driving compartment of the vehicle 2 .

[0094] How it works:

[0095] When the vehicle 2 breaks down, the driver and passengers control the operation of the power unit 203 through the operation button 201 inside the driving compartment, so that the avoidance device 1 is free from the constraint of the rotating rod 204, the top end falls toward the ground and triggers the button cover 10, so that the button cover 10 moves downward as a whole. In this process, the first guide surface 1011 on the first guide part 101 and the second guide surface 1021 on the second guide part 102 guide the sliding part 182 to move upward and simultaneously drive the thrust rod 183 and the force rod 189 to move upward. After being free from the push of the force rod 189, the block 184 moves toward the inner center of the fixed rod 16 under the elastic force of the third return spring 185, thereby being free from the position constraint on the second fixed seat 14, so that the first return spring 185, which was originally in a compressed state, pushes the second fixed seat 14 downward to move. Under the push of the second fixed seat 14, the first support frame 131 and the second support frame 132 are fully unfolded to form a tripod shape, completing the release process.
