Description
Technical Field
The utility model relates to a manufacturing field of selector, concretely relates to big envelope for car cable assembly.
Background
A cable assembly is a common output means of a vehicle shifter, and is generally disposed between a shift lever of the vehicle shifter and a transmission of the vehicle for transmitting displacement and force output from the shift lever to an input pin of the transmission.
A cable assembly may generally include a sleeve and a cable disposed in the sleeve and capable of reciprocating therein. The cable is disposed in the bushing generally considered to protect the moving part, the cable extending from the shift lever along the cable path up to the gearbox, from external interference and damage on the path along which it extends. In a common scenario, the cable path contains curved segments and the cable is flexible to better accommodate the structural requirements of different vehicle models. On this basis, in order to ensure that the cable can move freely in the sleeve without causing the sleeve to move back and forth along with the movement of the cable, it is common practice in the art to provide sleeve joints at both ends of the sleeve. The sleeve joint is sleeved outside the sleeve, so that the sleeve is allowed to be fixed relative to the body of the automobile through the sleeve joint. One possible embodiment is that the bushing terminal near one end of the gearbox is fixable to the gearbox bracket and the bushing terminal near one end of the gear shift lever is fixable to the shifter housing, thereby keeping both ends of the bushing stationary relative to the body of the car.
In order to accommodate possible movements of the parts of the cable at both ends of the bushing which protrude out of the bushing with respect to the bushing joint following the shift lever or the input pin of the transmission, it is currently common practice to arrange a rotary tube (driven tube) outside the end of the bushing which can be deflected with respect to the bushing joint away from the axial direction of the connected bushing. One end of such a rotary tube engages and can pivot relative to the bushing joint about this end as a pivot point, the other end of the rotary tube then correspondingly facing the gearbox or the gear shift lever or projecting out of the corresponding bushing joint. In this way, the sleeve joint actually functions to couple both the sleeve and the rotary pipe to each other.
The other end of the rotation tube opposite to the sleeve joint needs to be properly sealed to prevent dust, moisture, etc. from entering the gap between the rotation tube and the cable.
The prior art jacket is typically sleeved in an axial ring on the peripheral side wall of the rotary pipe by a circumferential inner flange, and furthermore has a single sealing lip extending away from the sleeve joint and pressing against the peripheral surface of the cable protruding from the rotary pipe. In order to improve the sealing effect, the manner adopted in the prior art is to keep the single sealing lip continuously in contact with the cable from the end of the rotating tube all the time, and to increase the positive pressure of the sealing lip on the cable passing through it by increasing the thickness of the sealing lip in the radial direction.
The single sealing lip and its corresponding technical development in the prior art make the cable more resistant during the axial movement with respect to the rotating tube, which is detrimental to the cable to perform its desired gear shifting function. On the one hand, this may lead to jamming of the shifting action, and on the other hand, this may lead to excessively rapid wear of the envelope.

Detailed Description
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below.
While the present invention will be described in conjunction with the exemplary embodiments, it will be appreciated that this description is not intended to limit the invention to those embodiments illustrated.
On the contrary, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention.
For convenience in explanation and accurate definition of the technical solutions of the present invention, the terms "upper", "lower", "inner" and "outer" are used to describe features of the exemplary embodiments with reference to the positions of these features as shown in the figures.
Various preferred but non-limiting embodiments of the envelope of the invention are described in detail below with reference to the accompanying drawings.
An enclosure 100 for an automotive cable assembly in accordance with a preferred embodiment of the present invention is shown in fig. 1. The envelope 100 comprises: a mounting portion 110, a plurality of sealing lips 120, and a deformation portion 130.
The mounting portion 110 cooperates with a rotating tube 200 of an automotive cable assembly arranged in the axial direction X to mount the jacket 100 on the rotating tube 200.
In the preferred embodiment shown in fig. 1, the mounting portion 110 may be generally cylindrical, with a circumferentially extending mounting flange 111 provided on the cylindrical inner wall of the mounting portion 110. For example, the mounting flange 111 may be used to cooperate with a collar on the rotary tube 200.
It is noted that the mounting shown in fig. 1 is only an example, and that a person skilled in the art can also envisage other mounting not shown in fig. 1 to mount the envelope 100 to the rotary tube 200 and make at least two relatively fixed in the axial direction X. Other attachment means include, but are not limited to, screwing or attachment by other removable conventional fasteners, etc., and are not described in detail herein.
The plurality of sealing lips 120 are distributed in the axial direction X to press against the outer circumferential surface of the cable 300 in a radial direction perpendicular to the axial direction X around the circumferential direction of the cable 300 passing through the jacket 100.
Preferably, and as schematically illustrated in fig. 1, the plurality of sealing lips 120 comprises three sealing lips 120. However, it can be understood by those skilled in the art that the number of the sealing lips 120 may also be two or more than three, and the axial length occupied by the sealing lips 120 and the radial thickness of each sealing lip 120 may also be selected according to practical situations, and will not be described herein again.
The deformation portion 130 is located between the mounting portion 110 and the plurality of sealing lips 120. The deformation of the deformation portion 130 allows the distance between the mounting portion 110 and the plurality of sealing lips 120 to vary. It will be understood by those skilled in the art that the distance between the mounting portion 110 and the plurality of sealing lips 120 is defined as a distance between the mounting portion 110 and the plurality of sealing lips 120 in the axial direction X. It will also be appreciated by those skilled in the art that the deformation of the deformation portion 130 is to allow axial play of the cable 300 therethrough, and thus, may preferably be elastic deformation.
With continued reference to fig. 1, the deformation 130 may maintain a radial gap with the cable 300 in a relaxed state. With regard to the above-described relaxed state, it is noted that, in this context, in the relaxed state of the deformation portion 130, the distance between the mounting portion 110 and the plurality of sealing lips 120 is greatest. It is also noted that the relaxed state here refers to a state that the deformation portion 130 naturally assumes without being elastically deformed by any external force. The radial gap presented in this relaxed state with the cable 300 may remain substantially uniform along the axial direction X or may have a varying radial gap along the axial direction X.
Still further, the deformation 130 may preferably be arranged such that when the deformation 130 is deformed and the distance between the mounting portion 110 and the plurality of sealing lips 120 is reduced, the deformation 130 is deformed radially outwardly away from the cable 300, i.e. the radial distance of at least a portion of the deformation 130 from the cable 300 becomes larger.
The deformation 130 may preferably be substantially cylindrical, and the deformation of the deformation 130 radially outward away from the cable 300 includes a radially outward bulging and bending of an axially central section of the cylindrical deformation 130, a specific form of which may be seen, for example, in fig. 1.
According to a preferred embodiment of the present invention, the deformation portion 130 may have a smaller radial thickness than the plurality of sealing lips 120, and more particularly, the deformation portion 130 may have a much smaller radial thickness than the plurality of sealing lips 120.
While the preferred embodiments of the present invention have been described in detail above, it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide yet further embodiments.
These and other changes can be made to the embodiments described herein in light of the above detailed description.
In general, in the claims, the terms used should not be construed to be limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
