Description

A kind of caravan carriage rear bumper mechanism
Technical field
The utility model is related to the technical field of caravan carriage rear bumper structure, insures after particularly a kind of caravan carriage Thick stick mechanism.
Background technology
Caravan has room and the big function of car two, but its attribute or car concurrently also known as the family on wheel, is a kind of removable, tool There is the car type of the basic facilities of herbal, caravan is, by the external fashion facility car type introduced, can be divided into driver area, daily life Region, bedroom region, hygiene sector, cooking area etc., caravan are to integrate clothing, food, shelter, OK, realize travelling, trip in life Lived in row, with the fast development of China's economic, increasing people thirsts for the whole family and goes on a journey together, popularization of the caravan in China Rate will more and more higher.
Caravan carriage rear bumper is a kind of peace for absorbing and relaxing foreign impacts power, protection vehicle body and occupant safety Full device, existing caravan carriage rear bumper is steel pipe, and is generally fixed to caravan carriage afterbody.When generation rear-end collision When, rear bumper is impacted by power, steel tube extrusion deformation, and last power is delivered to compartment afterbody causes compartment to be recessed, and threatens car Interior life safety.Due to being fitted on compartment tightly after rear bumper crimp, only carried out by force using hydraulic cutter Row cutting, this can undoubtedly cause to cut bad compartment, increase maintenance cost, and expense needed for new bumper is installed in addition is also expensive.
Utility model content
The purpose of this utility model is the shortcoming for overcoming prior art, there is provided a kind of compact conformation, safe and reliable, reduction The caravan carriage rear bumper mechanism that maintenance cost, shock rear bumper will not deform.
The purpose of this utility model is achieved through the following technical solutions:A kind of caravan carriage rear bumper mechanism, it is wrapped Caravan carriage and the rear bumper on the left of caravan carriage are included, the afterbody of described caravan carriage sets fluted, in groove Casing is provided with, multiple buffer units are provided with casing, described buffer unit is by cushion dashpot, piston, force-transmitting pole and rubber Pad composition, force-transmitting pole is arranged in cushion dashpot by the left part of cushion dashpot, is provided with force-transmitting pole in cushion dashpot and can edge The piston of cushion dashpot movement, the external part of force-transmitting pole is fixed with rubber blanket, and rubber blanket is fixed on rear bumper, on cushion dashpot and Hydraulic oil port is offered positioned at piston and cushion dashpot right part, the hydraulic oil port connection on two neighboring cushion dashpot, the caravan car Railway carriage or compartment rear bumper mechanism also includes overflow valve and damping spring, and described overflow valve is connected with any one hydraulic oil port, described Damping spring press between caravan carriage and rear bumper.
Mounting seat is provided with described cushion dashpot, cushion dashpot is fixed in casing through mounting seat.
Described cushion dashpot is set parallel to caravan carriage.
Two damping springs are compressed between described caravan carriage and rear bumper, two damping springs are on casing pair Claim to set.
The utility model has advantages below:The utility model is safe and reliable, reduce maintenance cost, clash into rear bumper not Can deform.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional views of Fig. 1;
Fig. 3 is the I portions partial enlarged view of Fig. 2;
In figure, 1- caravan carriages, 2- rear bumpers, 3- grooves, 4- casings, 5- cushion dashpots, 6- pistons, 7- force-transmitting poles, 8- Rubber blanket, 9- hydraulic oil ports, 10- overflow valves, 11- damping springs, 12- mounting seats.
Specific embodiment
The utility model is further described below in conjunction with the accompanying drawings, protection domain of the present utility model be not limited to It is lower described:
As shown in Fig. 1 ~ 3, a kind of caravan carriage rear bumper mechanism, it includes caravan carriage 1 and positioned at the left side of caravan carriage 1 The rear bumper 2 of side, the afterbody of described caravan carriage 1 sets to be provided with casing 4, casing 4 in fluted 3, groove 3 and sets There are multiple buffer units, described buffer unit is made up of cushion dashpot 5, piston 6, force-transmitting pole 7 and rubber blanket 8, and cushion dashpot 5 is parallel Set in caravan carriage 1, mounting seat 12 is provided with cushion dashpot 5, cushion dashpot 5 is fixed in casing 4 through mounting seat 12, force-transmitting pole 7 are arranged in cushion dashpot 5 by the left part of cushion dashpot 5, are provided with force-transmitting pole 7 in cushion dashpot 5 and can be moved along cushion dashpot 5 Dynamic piston 6, the external part of force-transmitting pole 7 is fixed with rubber blanket 8, and rubber blanket 8 is fixed on rear bumper 2.When rear bumper 2 is received When impact, damping spring 11 and rubber blanket 8 first play buffering, while also acting the effect of damping, it is to avoid caravan The vibrations on chassis, further prevent occupant to be dumped forward due to impulse inertia, protect personal security.
As shown in Fig. 2 offering hydraulic oil port 9, cushion dashpot 5 on cushion dashpot 5 and positioned at piston 6 and the right part of cushion dashpot 5 Interior and hydraulic oil is filled between the right part of piston 6 and cushion dashpot 5, the hydraulic oil port 9 on two neighboring cushion dashpot 5 connects Logical, the caravan carriage rear bumper mechanism also includes overflow valve 10 and damping spring 11, described overflow valve 10 and any one Hydraulic oil port 9 is connected, and described damping spring 11 is pressed between caravan carriage 1 and rear bumper 2.When rear bumper 2 is subject to During impact, overflow valve 10 can be opened, and the Opening pressure of overflow valve 10 can be adjusted arbitrarily.
Compressed two damping springs 11 between described caravan carriage 1 and rear bumper 2, two damping springs 11 on Casing 4 is symmetrical arranged.
The course of work of the present utility model is as follows:When rear bumper 2 is subject to impulsive force, damping spring 11 and rubber blanket 8 First play buffering, after 1 ~ 2ms, impulsive force is applied on force-transmitting pole 7 at once, force-transmitting pole 7 promotes piston 6 to extrude hydraulic pressure Oil, hydraulic oil hydraulic pressure gradually increases and opens overflow valve 10, before opening reaction force of the hydraulic oil to force-transmitting pole 7 to the left, Reaction force attenuation impulsive force, is delivered on caravan carriage 1 so as to be prevented effectively from impulsive force, it is ensured that the peace of personnel in compartment Entirely.In addition force-transmitting pole 7 has been compressed on rear bumper 2 and along its length, it is to avoid rear bumper 2 occurs bending and deformation, Without replacement operation after shock;Again because rear bumper 2 and caravan carriage 1 separate all the time, even if collide deformation also will not It is close on caravan carriage 1.
