Detailed Description
The present utility model, as shown in fig. 1 and 2, is a symmetrical vibration-damping mechanism applied to a wheelbarrow, comprising a main support frame 10 for mounting a frame and a wheel hub motor, two sets of link assemblies 20 mounted on both sides of the main support frame 10, two pedals 30 and a vibration damper 40, wherein:
the two pedals 30 are installed at two sides of the lower end of the main support 10 in a lifting manner, each group of connecting rod assemblies 20 comprises two first connecting rods 21 and two second connecting rods 22, the middle parts of the two first connecting rods 21 are correspondingly hinged to two sides of the main support 10, one ends of the two second connecting rods 22 are respectively hinged to the pedals 30, and the other ends of the two second connecting rods 22 are hinged to the lower ends of the first connecting rods 21 at the same side; the shock absorber 40 is connected to the upper ends of the first connecting rods 21, the pedal 30 moves downwards to prop the lower ends of the two first connecting rods 21 open to two sides through the two second connecting rods 22, and the upper ends of the first connecting rods 21 squeeze the shock absorber 40.
The main support frame 10 is U-shaped, and is provided with two support plates 11, and an accommodating space 12 capable of accommodating the hub motor is formed between the two support plates 11; hinge arms 13 for mounting the first links 21 are respectively arranged on the left and right sides of each supporting plate 11, and the middle parts of the first links 21 are hinged to the tail ends of the hinge arms 13. And, the upper ends of the two first links 21 located at both sides of the main support 10 and corresponding to each other in the thickness direction of the main support 10 are connected to each other by a pin 23, and the damper 40 is connected to the pin 23. The pin shafts 23 are adopted to connect the first connecting rods 21 on the two sides of the main support frame 10, so that the actions of the two corresponding first connecting rods 21 can be kept consistent, and the running stability of the wheelbarrow is improved.
The lower end of the main support frame 10 is vertically provided with a guide piece 50, and the pedal 30 can be installed on the guide piece 50 in a vertically sliding manner; and a stopper 60 is provided between the guide 50 and the pedal 30 to prevent the pedal 30 from moving excessively. The arrangement of the guiding structure has the following advantages: when the wheelbarrow is in the running process, the situation that the wheelbarrow is inclined due to the change of road conditions is difficult to avoid; at this time, the monocycle has a large unilateral stress, if the monocycle does not have a guiding structure, the positive pressure applied to the pedal 30 will be directly distributed to the first connecting rod 21 and the second connecting rod 22, which can cause the situation of blocking and damage of the hinge position of the connecting rod mechanism, so that the shock absorption is invalid. After the guide structure (the length of the guide structure is 6-7cm, and the specific size is set according to the requirement), the guide structure can share most positive pressure, so that the phenomenon of blocking caused by stress concentration due to the fact that most stress directly acts on the connecting rod mechanism is avoided, and the normal operation of the connecting rod mechanism is ensured. The guide structure provides a certain rigid limit support foundation for the whole support mechanism on one hand, so that the whole stress of the mechanism is more scientific and reasonable; meanwhile, the size of the support mechanism is smaller, so that the support mechanism has enough deflection under the action of the connecting rod, and the whole operation is smoother and more flexible.
In addition, if the weight of the corresponding user group is generally lighter, the guide structure can be omitted as long as the hinging matching stability between the connecting rods is enough; the step 30 may be hinged only to the two second links 22 without being in a mating relationship with the main support frame 10.
The limiting piece 60 can enable the pedal 30 to be lifted within a certain travel range, and the phenomenon of dead locking caused by the fact that the connecting rod is at a dead point position due to the fact that the pedal 30 is pressed down or moved up too far can be effectively avoided.
The specific structure of the guide member 50 and the limiting member 60 is as follows: the guide piece 50 is a guide rod, the pedal 30 is provided with a vertical sliding seat 31, and the vertical sliding seat 31 can be vertically slidably matched with the guide rod; the limiting piece 60 is a limiting boss arranged at two ends of the guide rod.
The shock absorber 40 is installed as follows:
the two sides of the upper end of the main support frame 10 are respectively provided with a supporting part 14, the supporting parts 14 on the two sides are positioned at the upper end of the main support frame 10, and the whole body is in a triangle shape, so that the distance between the upper ends of the two first connecting rods 21 and the supporting parts 14 on the same side is shorter, and the stroke of the shock absorber 40 is shortened; the shock absorbers 40 are respectively arranged between the upper ends of the two first connecting rods 21 and the supporting parts 14 on the same side, one end of each shock absorber 40 is hinged with the upper ends of the first connecting rods 21, and the other end of each shock absorber 40 is hinged with the supporting part 14; the damper 40 includes a damper and a damper spring sleeved outside the damper.
The damping supporting mechanism adopts the linkage principle that: the pedal 30 is pressed down, the second links 22 at the two sides outwardly support the lower ends of the first links 21 at the two sides away from each other by the pressing down of the pedal 30, the upper ends of the first links 21 at the two sides are closed to each other, and the distance between the upper ends of the first links 21 and the supporting portion 14 of the main support frame 10 is shortened, so that the damper 40 is pressed. Thereby, the depression force of the pedal 30 is converted into the rotational force of the first and second links 21 and 22, and is finally consumed by the damper 40, achieving a cushioning effect; when the pedal 30 loses the external force of pressing down, the restoring driving force of the shock absorber 40 drives the first connecting rod 21 and the second connecting rod 22 to reversely rotate and restore.
It should be noted that, the shock absorber 40 described in the present application has a damping function, and the principle thereof is not described herein.
The pedal 30 can only translate up and down along a straight line through the control of multiple connecting rods by connecting any first connecting rod 21 and any second connecting rod 22 to form a hinge point through a ball bearing or a joint bearing; meanwhile, due to the action of the second connecting rod 22, when the pedal 30 descends, the lower ends of the first connecting rods 21 on two sides are expanded outwards, and the upper ends are contracted and closed together, so that the shock absorber 40 is compressed, and a buffering function is realized; meanwhile, according to the relationship between the acting force and the reaction force, the compression forces at the two ends of the shock absorber 40 are equal, and the distribution of the first connecting rods 21 at the two sides is completely symmetrical and the sizes are the same. Therefore, the stress of the second connecting rods 22 hinged to the two sides of the lower part of the pedal 30 is the same, and the pedal 30 is ensured to translate up and down along the vertical direction.
The connection and cooperation of the first connecting rod 21, the second connecting rod 22 and the main support frame 10 adopt the lever principle, wherein the first connecting rod 21 corresponds to a lever, the second connecting rod 22 and the pedal 30 correspond to a force-generating end, the shock absorber 40 corresponds to a force-receiving end, and the whole operation is in the form of a lever. The magnitude of the moment can be changed by changing the ratio of the distances between the first link 21 and the both sides of the hinge point of the main support 10 to adjust the elastic force of the up and down movement of the pedal 30 and to select different dampers 40. Meanwhile, the lever mode is adopted, so that the whole size can be reduced under certain stress conditions, the occupied space is reduced, and the whole wheelbarrow is miniaturized and convenient to carry and transport.
The main support, the first connecting rod, the second connecting rod, the shock absorber and the pedal are matched with each other to form the connecting rod and slide rail composite support mechanism for the wheelbarrow, the support mechanism adopts a mode that the connecting rod and the slide rail structure are matched to enable the pedal to slide up and down to be converted into rotation of the connecting rod, the rotation of the connecting rod can be converted into the up and down movement of the pedal, the sliding and the rotation are converted mutually, and finally the shock is consumed by the shock absorber, so that the wheelbarrow can be effectively damped. Compared with the traditional large-distance guide rail type damping mechanism, the damping mechanism can effectively solve the problems of abnormal sound, blockage and poor comfortableness caused by long-term abrasion of the guide rail in the traditional mode; the wheelbarrow has the advantages of low running energy consumption, low noise, better smoothness, improved working stability and use experience comfort of the wheelbarrow, and meanwhile, the size of the guide rail is greatly shortened, the defect of poor rigidity of the large-size guide rail of the traditional wheelbarrow is avoided, and the production cost is reduced.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the technical scope of the present utility model, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
