Description

Technical Field

[0001] The utility model relates to the technical field of mechanical structure design, in particular to a stable and symmetrical force guiding device. Background Art

[0002] In engineering technology, mechanical structures are susceptible to damage when subjected to external impact. In order to reduce the damage, it is usually necessary to improve the structural strength, material strength or add shock absorbing devices. However, as the external impact is unpredictable, it is impossible to completely avoid structural damage through such improvement ideas.

[0003] For example, the car bumper is installed at the front and rear ends of the car. It not only has a decorative function, but more importantly, it is a safety device that can absorb and mitigate external impact and protect the front and rear parts of the car body.

[0004] When an existing automobile bumper is hit, due to the different directions and angles of the impact force, the force-bearing surface is subjected to uneven impact force, which is very likely to cause the symmetrically arranged connecting rods to rotate at different angles, thereby causing the force-bearing surface to tilt, resulting in the impact force being unable to be evenly transmitted to both sides. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a stable and symmetrical force-guiding device, which can rotate the symmetrically arranged connecting rods to the same angle, thereby completely solving the problem that the force received by the mechanical structure cannot be evenly transmitted to both sides. It can be understood that, if applied to a car bumper, it can solve the technical problem that when a car is hit, the car bumper is hit by different directions and angles of the impact force, which causes the symmetrically arranged connecting rods to rotate at different angles, thereby causing the force-bearing surface to tilt, thereby causing the impact force to be unable to be evenly transmitted to both sides.

[0025] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0026] Embodiment 1

[0027] like Figure 1 and Figure 3 As shown, a stable and symmetrical force guiding device of this embodiment includes a mounting rod 1, a first force guiding component 2 and a second force guiding component.

[0028] Specifically, the first force guiding component 2 includes at least one force-bearing surface 21 and at least one pair of first force guiding rods 22. The first end of the first force guiding rod 22 is movably connected to the force-bearing surface 21, and the second end is movably connected to the slide 24. The slide 24 can and can only slide along the mounting rod 1; when the force-bearing surface 21 is subjected to a pressure perpendicular to the mounting rod 1, the slide 24 slides along the mounting rod 1 so as to be able to laterally push against a second force guiding component slidably mounted on the mounting rod 1, so that the second force guiding component generates a thrust in a direction different from the pressure. Among them, the slide 24 can and can only slide along the mounting rod 1, including the slide 24 being sleeved on the mounting rod 1 or being limited to sliding in a long groove opened along the length direction on the mounting rod 1, that is, one is that the slide 24 is sleeved on the mounting rod 1, and the second end of the first force guiding rod 22 is movably connected to the slide 24 and can slide on the mounting rod 1, so that when the force-bearing surface 21 is subjected to pressure perpendicular to the mounting rod 1, the slide moves along the mounting rod 1, and then pushes the second force guiding component; the other is that a long groove is opened on the mounting rod 1, and the second end of the first force guiding rod 22 is movably connected to a slide in the form of a roller or a slider, and the roller or the slider is movably placed in the long groove extending along the length direction of the mounting rod 1. When the force-bearing surface 21 is subjected to pressure perpendicular to the mounting rod 1, the roller or slider moves along the long groove, thereby pushing the second force guiding component, so that the second force guiding component generates a thrust in a direction different from the pressure; in addition, a gear 23 is fixedly provided on the first end of each first force guiding rod 22, and the gear 23 is rotatably connected to the bottom of the force-bearing surface 21 by means of a pin shaft 25. The first force guiding rods 22 are paired in pairs, and the first ends of each pair of first force guiding rods 22 are meshed with each other by means of the gears 23. When the force-bearing surface 21 is subjected to pressure perpendicular to the mounting rod 1, the meshing gears 23 cause the corresponding pair of first force guiding rods 22 to rotate synchronously in opposite directions around the pin shaft 25 by the same angle. By setting at least one force-bearing surface 21, at least one pair of first force-guiding rods 22 and fixing a gear 23 at the first end of each first force-guiding rod 22, it can be achieved that when the force-bearing surface 21 is subjected to impact forces in different directions and angles, the force-bearing surface 21 approaches the direction of the mounting rod 1. Since the gears 23 are meshed with each other, when the gear 23 rotates, the pin shaft 25 rotates with the rotation of the gear 23, thereby driving the first force-guiding rod 22 to rotate with the rotation of the pin shaft 25. In addition, due to the action of the gear 23, at least one pair of first force-guiding rods 22 can rotate synchronously at the same angle around the pin shaft 25 in opposite directions. That is, when the force-bearing surface 21 is subjected to impact forces in different directions and angles, it can avoid the force-bearing surface 21 from tilting, thereby avoiding the situation where when pressures in different directions or angles are applied to the force-bearing surface 21, the pressure toward the force-bearing surface 21 cannot be evenly converted into a force along the mounting rod 1 and transmitted toward both sides of the mounting rod 1.

[0029] Furthermore, the gear 23 includes a complete gear and / or an incomplete gear, and the parameters of the gears 23 meshing with each other are the same, so that when at least one pair of first force guiding rods 22 rotates with the pin shaft 25, the parameters of the gears 23 meshing with each other are the same. Therefore, the rotation rate and rotation angle of at least one pair of first force guiding rods 22 are the same during rotation. Therefore, when pressure at different angles and in different directions toward the force-bearing surface 21 is applied to the force-bearing surface 21, the rotation rate and rotation angle of at least one pair of first force guiding rods 22 can be the same, so that the pressure applied to the force-bearing surface 21 can be converted into a force transmitted along both sides of the mounting rod 1, so as to push the second force guiding component and transmit the force to other components for offset.

[0030] Furthermore, two force-bearing surfaces 21 are relatively arranged on both sides of the mounting rod 1, and the force directions of the two force-bearing surfaces 21 are relatively perpendicular to the mounting rod 1, so that the force guiding device can withstand pressure from two different directions, making the force guiding device more applicable and practical, and when the force guiding device is installed on other required devices, its safety will also be improved accordingly.

[0031] Furthermore, two pairs of first force guiding rods 22 whose first ends are meshed with each other are movably installed at the bottom of each force-bearing surface 21. The two pairs of first force guiding rods 22 are crossed in pairs to form four X-shaped structures on both sides of the mounting rod 1. Through the X-shaped structure, it is possible to transmit the pressure impacting the force-bearing surface 21 to the X-shaped structure, that is, when the force-bearing surface 21 is subjected to the impact force, the force-bearing surface 21 moves toward the mounting rod 1. At the same time, the gears 23 on the first ends of the first force guiding rods 22 mesh with each other and rotate. During this period, the force-bearing surface 21 always maintains the initial state, and the two first force guiding rods 22 of the X-shaped structure rotate around the pin shaft 25 due to the rotation of the gear 23. In other words, the two first force guiding rods 22 of the X-shaped structure rotate around the pin shaft 25. The angle between the force guiding rods 22 changes, and the X-shaped structure is in a compressed state, that is, the force applied to the force-bearing surface 21 is transferred to the force along the direction of the mounting rod 1, and thereby transferred to the second force guiding component; the two X-shaped structures extending toward the same side of the mounting rod 1 are connected to the same imitation deflection seat at the intersection, and by providing an anti-deflection seat 26, it is possible to ensure that the first force guiding rod 22 of the X-shaped structure can remain in the same plane under compression and tension, that is, to avoid the first force guiding rod 22 of the X-shaped structure from deviating when transmitting force, which may cause the first force guiding rod 22 to deform or directly break, and further cause the force applied to the force-bearing surface 21 to be unable to continue to be transmitted.

[0032] Furthermore, the second end of each first force guiding rod 22 in the X-shaped structure is movably connected to a short arm force guiding rod 27, and a plurality of short arm force guiding rods 27 form a short arm X-shaped structure extending to both sides from the second end of each first force guiding rod 22. By providing the short arm force guiding rod 27, when the force bearing surface 21 is subjected to very small pressure, the first force guiding rod 22 can also be smoothly compressed. If a first force guiding rod 22 of the same length is set to replace the short arm force guiding rod 27, when the force bearing surface 21 is subjected to very small pressure, due to the limitation of the length of the first force guiding rod 22, in the initial state, multiple first force guiding rods 22 are in a compressed state, and it is very likely that a small pressure will not be able to compress multiple first force guiding rods 22 and transmit the pressure; and by setting the short arm force guiding rod 27, it can be achieved that the first force guiding rod 22 is not limited by length during installation, and the short arm force guiding rod 27 can reduce the length of the first force guiding rod 22 on the mounting rod 1, thereby reducing the installation space of the first force guiding assembly 2 on the mounting rod 1, and even if the force bearing surface 21 is subjected to very small pressure, since the first force guiding rod 22 is not in an extreme compression state in the initial state, even a small force can compress the first force guiding rod 22, and then transmit the pressure to the force along the mounting rod 1. Preferably, the short arm X-shaped structure includes four groups, eight groups or more, which can make the first force guiding assembly 2 more stable when transmitting pressure and can save more installation space.

[0033] The structure of the second force guide component is the same as the structure of the second force guide component in the utility model patent with application number 202420320880.X. All technical features of the second force guide component are combined here for reference, and the structure of the second force guide component will not be repeated here.

[0034] Embodiment 2

[0035] like Figure 2 As shown, a stable and symmetrical force guiding device of this embodiment is different from the first embodiment in that the second end of the first force guiding rod 22 installed at the bottom of each force-bearing surface 21 facing the same side of the mounting rod 1 is movably connected to the same sliding seat 24. It has a simple structure and saves the installation space of the first force guiding component 2. When the force-bearing surface 21 is subjected to pressure at different angles and directions, the first force guiding rod 22 rotates around the axis of the pin shaft 25, and the gear 23 rotates with the rotation of the first force guiding rod 22, so that the rotation angles of the two relative first force guiding rods 22 are the same, so that no matter what direction and angle the force-bearing surface 21 is subjected to pressure, the pressure can be evenly transmitted to the first force guiding rod 22, and the pressure is converted into a force transmitted along the direction of the mounting rod 1 by the compression of the first force guiding rod 22, so that the first force guiding rod 22 transmits the force to the second force guiding component.
