Description

Technical Field

[0001] This utility model belongs to the field of engineering vehicle safety protection technology, specifically relating to a multi-degree-of-freedom adjustment device for installing anti-collision buffer pads. Background Technology

[0002] With the rapid development of the transportation industry, the number of scenarios where engineering vehicles and civilian vehicles share the road is increasing. These vehicles are diverse in type and travel at high speeds, and once a collision occurs, it often causes serious injury and damage to surrounding people and facilities.

[0003] Currently, traditional crash barrier installation mechanisms have many limitations. Existing crash barriers have fixed height, lateral position, and angle after installation. This fixed design cannot meet the installation requirements of different vehicles or the needs of collisions at varying speeds and angles. In practical applications, the following drawbacks exist:

[0004] 1. It cannot adapt to the differences in collision contact points between different vehicle models (such as the low front of a sedan and the high chassis of a truck);

[0005] 2. Rigid fixed structures are prone to generating lateral impact moments during oblique collisions, reducing their buffering effect;

[0006] 3. The fixed location limits the protection range and makes it difficult to cope with complex road environments.

[0007] In existing technologies, although the installation devices for crash buffer pads have some adjustment mechanisms, they are mostly single-degree-of-freedom designs, unable to simultaneously achieve multi-dimensional adjustments in height, lateral position, and angle, making it difficult to meet the protection requirements under complex working conditions. Therefore, there is an urgent need for a crash buffer pad installation device capable of multi-degree-of-freedom adjustment to improve the protective effect and safety of crash buffer pads.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. These descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the claims of this utility model. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] This embodiment provides a multi-degree-of-freedom adjustment device for installing anti-collision buffer pads, such as... Figure 1 , Figure 2 As shown, the device includes a chassis 75, a transfer bracket assembly, a mounting base plate 3, a transverse support assembly, a tilting bracket base 601, a tilting bracket 11, and an anti-collision buffer pad 12. The device is based on the chassis 75, with the left and right transfer brackets 101 and 102 bolted to the chassis 75. The left dovetail slide plate 201 and the left transfer bracket 101, and the right dovetail slide plate 202 and the right transfer bracket 102, respectively, achieve sliding engagement through dovetail grooves. The mounting base plate 3 is fixed to the two dovetail slide plates by fastening screws 20 and 21, forming the basic structure for vertical adjustment. The left and right transverse support brackets 401 and 402 are fixed to the mounting base plate 3 by fastening screws 20, providing support for horizontal adjustment. The flip bracket base 601 is connected to the transverse support assembly via a horizontal adjustment mechanism and can move horizontally. The flip bracket 11 is connected to the flip bracket base 601 via a flip mechanism and can flip relative to it. The anti-collision buffer pad 12 is fixed on the flip bracket 11. Multi-degree-of-freedom adjustment is achieved through the cooperation of various components.

[0031] Furthermore, such as Figure 3 As shown, the vertical adjustment mechanism includes a left vertical cylinder 103 and a right vertical cylinder 104. When the vertical adjustment mechanism is working, the two ends of the left vertical cylinder 103 are hinged to the left dovetail slide plate 201 and the left adapter bracket 101 via pins 7 (507) and 10 (510), respectively. The two ends of the right vertical cylinder 104 are hinged to the right dovetail slide plate 202 and the right adapter bracket 102 via pin 8 (508), respectively. When the left vertical cylinder 103 and the right vertical cylinder 104 extend or retract, they cause the left and right dovetail slide plates 201 and 202 to slide up and down along the dovetail grooves of the left and right adapter brackets 101 and 102, thereby adjusting the vertical position of the upper components via the mounting base 3.

[0032] Furthermore, such as Figure 4As shown, when the horizontal adjustment mechanism is in operation, the motor 10 starts and transmits power to the planetary reducer 9. The planetary reducer 9 is fixed to the left 401 of the transverse support, and its power drives the lead screw 403 inserted into the inner hole to rotate. The lead screw nut 1 404 and lead screw nut 2 405 fixed on the lead screw 403 rotate with the lead screw 403. Since the lead screw 403 is fixed in the inner hole of the right 402 of the transverse support through the bearing 406, the rotation of the lead screw 403 will drive the lead screw nut 1 404 and lead screw nut 2 405 to move axially along the lead screw 403. At the same time, the two ends of the smooth rod 1 802 and smooth rod 2 803 are respectively fixed in the countersunk holes of the left 401 and the right 402 of the transverse support. The linear bearing 1 801 on the smooth rod 1 802 and the linear bearing 2 804 on the smooth rod 2 803 can move left and right along the smooth rod, and are respectively fixed inside the linear bearing seat 1 701 and the linear bearing seat 2 702. The flip bracket base 601 is fixed to the linear bearing housing 701 and the linear bearing housing 702 by fastening screw 3 22, and to the lead screw nut 404 and the lead screw nut 405 by fastening screw 4 23. Therefore, when the lead screw 403 drives the lead screw nut to move, the flip bracket base 601 will slide smoothly along the smooth rod with the help of the linear bearing under the drive of the lead screw nut, so as to achieve stable horizontal movement adjustment.

[0033] Furthermore, such as Figure 5 As shown, when the tilting mechanism is working, one end of the tilting cylinder 131 is hinged to the tilting bracket base 601 via pin 501, and the other end is hinged to the tilting bracket 11 via pin 503. The tilting bracket 11 is hinged to the tilting bracket base 601 via pin 502. One end of the tilting cylinder 132 is hinged to the tilting bracket base 601 via pin 504, and the other end is hinged to the tilting bracket 11 via pin 506. The tilting bracket 11 is hinged to the tilting bracket base 601 via pin 505. When the tilting cylinders 131 and 132 extend or retract, they push the tilting bracket 11 to rotate around the pins connected to the tilting bracket base 601, thereby adjusting the tilting adjustment of the tilting bracket 11 relative to the tilting bracket base 601 and thus adjusting the angle of the anti-collision buffer pad 12.

[0034] Furthermore, when installing the anti-collision buffer pad 12, align the anti-collision buffer pad 12 with the bolt holes on the flip bracket 11, and fix the anti-collision buffer pad 12 to the flip bracket 11 by passing the bolts through the bolt holes, thus completing the installation and fixing of the anti-collision buffer pad 12 and ensuring its stability on the flip bracket 11 so that it can be adjusted in various directions with the flip bracket 11 in the future.

[0035] The above description only describes the preferred embodiments of the present utility model. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model, and all such changes should be included within the protection scope of the present utility model.
