Description

A kind of roller detent mechanism

Technical field

The utility model relates to the mechanical positioning technical field, especially a kind of roller detent mechanism.

Background technology

Because problems such as the in short supply and environmental pollutions of global energy, the development new-energy automobile has become the important trend of countries in the world automobile industry development, and at present, electric automobile has progressively begun popularization and application as the main force of new-energy automobile.Electric automobile is meant with the vehicle power to be power, and with the vehicle that power wheel travels, it utilizes the electric energy that is stored in the battery to start.For providing the battery case of electric power, electric automobile is arranged on usually on the battery bracket of electric automobile, on battery case and battery bracket, be provided with quick electric connector accordingly, and fast electric connector is to be provided with along the direction that battery case pushed/pulled out battery bracket, when battery case is pushed into battery bracket arrival service position, the snap joint success of pegging graft simultaneously, this moment, battery case just can provide driving power for electric automobile.

Battery case is being pushed in the process of battery bracket, in case the position of battery case is offset, will cause quick electric connector successfully to peg graft, and because the batteries of electric automobile case is all heavier usually, adjust the battery case position once more requires great effort very much, therefore, snap joint in order to ensure battery case and battery bracket can quick and precisely be pegged graft, a kind of battery in place mechanism has appearred in the prior art, as disclosing a kind of detent mechanism of Vehicular battery among the Chinese patent literature CN201188435Y, comprise: the framework that is used to accommodate battery case, bottom at this framework is provided with roller, this roller is provided with the guiding battery case and enters into gathering sill in the framework according to predetermined direction, on the sidepiece of described framework, also be equipped with and be used for described battery case is locked at electromagnetic lock in the described framework, but this electromagnetic lock has the tapered end of elastic telescopic.This detent mechanism is by on the roller of framework (battery bracket) bottom roller groove being set, and the guide rail of battery case (battery case) bottom can slide on roller groove, thereby the guiding battery case enters in the framework according to predetermined direction.But there is following problem in above-mentioned detent mechanism: 1. because the cross sectional shape of this roller groove is semicircle, there is big fit clearance between roller groove and the guide rail, this just makes understands double swerve when battery case moves on roller, the position of battery case will be offset, and can't guarantee the accurate grafting of quick electric connector; 2. after battery case reaches the service position, in order to guarantee that the battery case position is not jolted by car body and influenced, can about on the direct of travel, locate, above-mentioned detent mechanism is provided with parts such as alignment pin at the sidepiece of framework, though parts such as alignment pin can be realized the purpose of locating about it, but having increased these parts must make its structure become complicated, and owing to electric automobile often all relatively jolts in the process of moving, in case superstructure loosenings such as alignment pin are thrown off, the battery case position will change, cause the quick electric connector loose contact between battery case and the battery bracket, contact resistance increases, influence the normal power supply of battery case to electric automobile, seriously also might cause quick electric connector to burn out, influence the safety traffic of electric automobile; 3. in addition, above-mentioned detent mechanism is the shaping roller groove on roller, also can cause roller to concentrate the easy flexural deformation in roller groove place at bearing capacity decline, the stress of roller groove position, easilier cause the battery case offset, can't guarantee the accurate grafting of quick electric connector.

In addition, adopt roller to cooperate in the industry field that conveys goods with track at other, also exist similar problem, because it is semicircle that the cross sectional shape of track mostly is greatly, exist bigger fit clearance between roller and the track, skew even skid off track about making when roller orbits easily can not convey goods towards fixed-direction rapidly and accurately, makes goods transport very effort, time-consuming.

The utility model content

For this reason, technical problem to be solved in the utility model is detent mechanism of the prior art because the cross sectional shape of track mostly is semicircle greatly, there is big fit clearance between roller and the track, in the roller running easily about skew even skid off track, the technical problem that can not advance towards fixed-direction rapidly and accurately, and provide a kind of simple in structure, can guarantee about roller location and the roller detent mechanism that can advance towards fixed-direction.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of roller detent mechanism comprises track, is arranged on the horizontal plane; Roller is arranged on the bottom that needs mobile object, and the wheel shaft of described roller is perpendicular to the bearing of trend of described track, and described roller is suitable for rolling on described track and advances; The bus of the wheel face of described roller is the arc with respect to the radial section symmetry of described roller, and described track is the uncovered grooved that makes progress, and the inner surface of described track both sides is the tapered plane that is acute angle with vertical direction.

In the above-mentioned rollers detent mechanism, the bus of described wheel face is a semicircular arc.

In the above-mentioned rollers detent mechanism, the angle between the described inner surface in the both sides of described track is the 60-120 degree.

In the above-mentioned rollers detent mechanism, the angle between the described inner surface in the both sides of described track is 90 degree.

In the above-mentioned rollers detent mechanism, the cross sectional shape of described track is a V-shape.

Technique scheme of the present utility model has the following advantages compared to existing technology:
