Description

A kind of automobile door stopper

Technical field

The utility model relates to stop, particularly a kind of automobile door stopper.

Background technology

Car door limiter is one of parts crucial in the sedan door system, and current customer is more and more paid close attention to the comfortableness that automobile uses, and stop answers noiselessness to occur when gear shift, and during gear shift, gear is clear.Usually, what car door limiter adopted is block rubber, relies on block rubber self elasticity and guide rail shape to carry out spacing, under low temperature environment, and block rubber elasticity variation, gear clamping stagnation and abnormal sound, noise problem easily appear in car door limiter.

The utility model content

The purpose of this utility model is, by a kind of car door limiter is provided, and solving under low temperature environment, block rubber elasticity variation, gear clamping stagnation and abnormal sound, noise problem easily appear in car door limiter.

For realizing above purpose, the utility model provides following technical scheme:

A kind of automobile door stopper comprises:

The stop box;

Position limit arm;

The stop fixed support;

Spacing pressing plate;

be symmetrically arranged with two groups of springs in described stop box, steel ball seat and steel ball, described spring is against described stop box inwall, described steel ball seat one end is against on described spring, the other end is divided and is held described steel ball, on the middle part of described position limit arm, soffit all has the stroke groove, be provided with limited impression in described stroke groove, and the degree of depth of described limited impression is greater than the degree of depth of described stroke groove, described position limit arm passes described stop box, one end is connected with described stop fixed support pivotable, the other end is fixedly connected with described spacing pressing plate, described steel ball and described stroke groove are movingly.

Selectively, described position limit arm is the metallic framework flat bar with plastic wraps layer, and described stroke groove is positioned on described plastic wraps layer.

Selectively, seal by dust-proof cushion between described stop box and described position limit arm.

Selectively, be provided with rubber pad between described spacing pressing plate and described stop box.

The utility model compared with prior art has following obvious advantage and beneficial effect:

Owing to being symmetrically arranged with spring, steel ball seat and steel ball in the stop box, providing elastic force that steel ball is remained on by spring rolls in the stroke groove of position limit arm or locates in limited impression, elastic force is subjected to low temperature effect less, and the deformation that the steel ball temperature influence produces is less, and when having avoided low temperature, elasticity dies down and the deformation of parts and the problem that causes opening clamping stagnation and abnormal sound noise.

Further, as skeleton, outsourcing plastic wraps layer when having guaranteed position limit arm rigidity, can make steel ball move in the stroke groove more steady to position limit arm, has further reduced noise with metal.

Further, between stop box and position limit arm, dust-proof cushion is set, has prevented that dust from entering the stop box, avoided steel ball to produce because being subject to polluting the retardance of rolling, guarantee that operation is level and smooth, noise reduction.

Further, between spacing pressing plate and stop box, rubber pad is set, when making car door be in extreme position, can produce abnormal sound because of strong collision between spacing pressing plate and stop box.

Fig. 5 is the A-A generalized section of Fig. 2.

Wherein, 1 is spacing pressing plate, and 2 is the steel ball seat, 3 is spring, and 4 is that installing plate 5 is dust-proof cushion, and 6 is position limit arm, 7 is rivet, and 8 is the stop fixed support, and 9 is steel ball, 10 is the stop housing, 11 is rubber pad, and 13 is the stroke groove, and 20 is the metallic framework flat bar, 21 is the plastic wraps layer, and 22 is limited impression.

The specific embodiment

Below in conjunction with Figure of description, the specific embodiment of the present utility model is illustrated:

In conjunction with Fig. 1, Fig. 2, from the outside, the stop box of automobile door stopper comprises the installing plate 4 of stop housing 10 and sealing stop housing 10, has the devices such as bolt that are connected with vehicle body on installing plate 4.Position limit arm 6 passes the stop box, and an end is connected with stop fixed support 8 pivotables by rivet 7, and the other end is fixedly connected with spacing pressing plate 1.Those of ordinary skills can imagine at an easy rate, can also realize that pivotable is connected by the suitable structure such as bolt, universal joint, cup-and-ball joint between position limit arm 6 and stop fixed support 8.By dust-proof cushion 5 sealings, inner to prevent that dust from entering the stop box between preferred stop box and position limit arm 6.Be provided with rubber pad 11 between preferred spacing pressing plate 1 and described stop box, produce strong collision between spacing pressing plate 1 and stop box when avoiding opening/closing door of vehicle to extreme position.

With reference to figure 3, it shows in detail the internal structure of stop box.Be symmetrically arranged with two groups of springs 3, steel ball seat 2 and steel ball 9 in the stop box.

With reference to figure 4, upper and lower surface, the middle part of position limit arm 6 all has stroke groove 13, be provided with limited impression 22 in stroke groove 13, and the degree of depth of limited impression 22 is greater than the degree of depth of stroke groove 13, so that steel ball 9 is when the interior rolling of stroke groove 13, can fall into limited impression 22 and location, thereby realize that the car door gear is spacing.Preferred position limit arm 6 is for having the metallic framework flat bar 20 of plastic wraps layer 21, and stroke groove 13 is opened on plastic wraps layer 21.As previously mentioned, as skeleton, outsourcing plastic wraps layer 21 in the rigidity that has guaranteed position limit arm 6, can make steel ball 9 more steady in the interior motion of stroke groove 13 to position limit arm 6, has further reduced noise with metal.Certainly, position limit arm 6 also can be by single metal material manufacturing, but obviously outsourcing plastic wraps layer has more advantage.

With reference to figure 5, it shows in detail the matching relationship between each parts and the matching relationship of stop box and position limit arm 6 in the stop box.As seen from the figure, in the stop box, spring 3 is against the inwall of stop housing 10, and steel ball seat 2 one ends are against on spring 3, and the other end is divided and held steel ball 9.Under the pressure of spring 3, steel ball 9 is in the stroke groove 13 on upper and lower surface of the outer plastic wraps layer 21 of metallic framework flat bar 20 all the time, and can roll in stroke groove 13.During the open and close car door, position limit arm 6 produces relative motion with the stop box, and steel ball 9 rolls in stroke groove 13, and can fall into limited impression 22 or therefrom break away from, thereby realizes that the gear in the switch gate process is spacing, and makes switch gate steady.When reaching the limit of the position, spacing pressing plate has limited the further motion of position limit arm 6 in the stop box.Steel ball 9 is difficult for producing low-temperature deformation, and spring 3 elasticity when low temperature can not reduce, and has solved and has opened the problem of clamping stagnation and abnormal sound noise under the cryogenic conditions.

It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this manual has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can modify or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of the spirit and scope of utility model, and it all should be encompassed in the middle of claim scope of the present utility model.
