[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Reference Figures 1 to 4 As shown, a pedestrian protector pipe assembly device includes a base 1, which is used to place a bracket a; it also includes an oblique pressing block 2, which moves in an oblique direction and presses on the upper end of the bracket a; the base 1 is provided with a clearance hole 11, and a lifting column 3 is provided above the clearance hole 11. The lifting column 3 is used to install a straight pipe b. The lifting column 3 drives the straight pipe b to be inserted into the clearance hole 11 and connects the straight pipe b to the bracket a; a clamping plate 4 and a translation plate 5 are respectively provided on both sides of the straight pipe b, and the straight pipe b is clamped by the clamping plate 4 and the translation plate 5 to separate the straight pipe b from the lifting column 3.

[0025] When in use, first place the bracket a on the base 1, then press the upper end of the bracket a by obliquely moving the pressure block 2, insert the upper end of the straight tube b into the lifting column 3, then the lifting column 3 moves downward and inserts the straight tube b into the through hole a1 of the bracket a, and then fix the straight tube b by the clamping plate 4 and the translation plate 5. Finally, the lifting column 3 moves upward and detaches from the straight tube b, completing the assembly of the straight tube b and the bracket a.

[0026] When the size of the through hole a1 of the bracket a is too small, the straight pipe b is forcibly inserted into the through hole a1 of the bracket a through the assembly device of the utility model to complete the assembly of the two. There is no need to expand the hole of the bracket a, which reduces the complexity of assembling the bracket a and the straight pipe b. In addition, the interference fit assembly method of the bracket a and the straight pipe b can also make the assembly of the two more firm and stable.

[0027] The oblique pressing block 2 is provided with two pressing plates 21 distributed on both sides of the straight pipe b. By pressing the bracket a with the two pressing plates 21, the bracket a can be prevented from being offset when the bracket a is impacted by the pipe, thereby preventing the pipe from being accurately inserted into the through hole a1.

[0028] The pressing plate 21 is provided with an arc-shaped corner 211 that abuts against the bracket a. The oblique pressing block 2 moves in a predetermined tilting direction, and when it moves to a certain position, it begins to press the upper end of the bracket a. During this pressing process, the flat part of the pressing plate 21 does not directly contact the flat part of the bracket a, but first contacts the arc-shaped corner 211 on the pressing plate 21. The design of this arc-shaped corner 211 makes it possible for the pressure of the pressing block on the bracket a to gradually increase at the initial stage of contact, rather than suddenly applying a large force. This gradually increasing pressure has several advantages: it can give the bracket a a gradual adaptation process, avoiding damage or instability of the bracket a due to sudden pressure changes.

[0029] In order to enable the oblique pressure block 2 to move in a predetermined tilting direction, the pedestrian protection device pipe fitting assembly device of the present invention further includes an oblique driving member 6, the output end of which is connected to the oblique pressure block 2. The base 1 is fixed with a first fixed block 12, the first fixed block 12 is provided with an installation bevel 121, the oblique driving member 6 is fixed to the installation bevel 121, and the first fixed block 12 is provided with a plurality of guide rods 122 perpendicular to the installation bevel 121, and the guide rods 122 pass through the oblique driving member 6. The above structure enables the oblique pressure block 2 to move in a predetermined tilting direction, wherein the oblique driving member 6 can use a pneumatic cylinder, an oil cylinder, an electric screw, or other mechanism to drive the oblique pressure block 2 to move.

[0030] The angle between the mounting bevel 121 and the base 1 is 65° to 75°. By setting the mounting bevel 121, the obliquely movable pressing block 2 can abut against the bracket a along the angle and apply pressure.

[0031] The base 1 is fixed with a second fixing block 13 and a third fixing block 14. The third fixing block 14 has a guide hole 141. The second fixing block 13 is fixed with a translation driver 7. The output end of the translation driver 7 passes through the guide hole 141 and is connected to the translation plate 5. This structure enables the translation plate 5 to translate in a predetermined direction. The translation driver 7 can use a pneumatic cylinder, oil cylinder, electric screw, or other mechanism to drive the translation plate 5 to move.

[0032] The base 1 is further provided with two spaced-apart lifting actuators 32 and two spaced-apart guide posts 33. Return springs 34 are sheathed around the guide posts 33 and positioned between the base 1 and the lifting plate 31. The lifting actuators 32 are used to drive the lifting plate 31 up and down. This structure allows the lifting actuators 3 to move up and down in a predetermined direction. The lifting actuators 32 can utilize mechanisms such as pneumatic cylinders, oil cylinders, and electric screws to drive the translation plate 5.

[0033] The clamping plate 4 is provided with an arc-shaped notch 41 that is buckled into the side end of the straight tube b. The translation plate 5 is provided with a V-shaped notch 51 that is buckled into the side end of the straight tube b. The coordination of the arc-shaped notch 41 and the V-shaped notch 51 enables the straight tube b to be stably clamped.

[0034] Two positioning posts 15 are provided on the upper end surface of the base 1, and bracket a has positioning holes a2 adapted to accommodate these posts 15. The cooperation between the posts 15 and the holes a2 prevents horizontal displacement of bracket a placed on the base 1, thus preventing misalignment between the support plate's through-hole a1 and the base 1's clearance hole 11, which could prevent the pipe from being properly inserted into the through-hole a1.
