Description

[Technical Field]

[0001] The present invention generally relates to the technical field of conductive fabrics, and more particularly to an automobile steering wheel functional cover with a tongue protection structure and a steering wheel. [Background technology]

[0002] The conventional electrical connection method between the conductive fabric and the harness is welding or ultrasonic welding, but due to the requirement of assembly size, the connection area between the conductive fabric and the harness is designed to be relatively narrow, which reduces its bending resistance, and bending of the connection area is unavoidable during the manufacturing, transfer, packaging, etc.

[0003] As the number of times the conductive fabric is folded increases, the area of ​​the plating layer at the folding position of the conductive fabric that has fallen off becomes larger and larger, and the conductivity of the conductive fabric deteriorates. After the plating layer is completely fallen off, the conductive fabric loses its conductive function, which affects the normal function of the device.

[0018] The present invention will be described in more detail below in conjunction with the drawings and examples. The specific examples described herein do not limit the present invention, but are merely used to interpret the relevant utility model. For ease of explanation, only the relevant parts of the utility model are shown in the drawings.

[0019] Hereinafter, the present invention will be described in detail in conjunction with the embodiments with reference to the accompanying drawings.

[0020] Example 1 Referring to Figures 1 to 4, the present invention provides a functional cover for an automobile steering wheel with a tongue protection structure, a functional cover body (1) comprising a functional part and a tongue part (15) protruding from the functional part, the functional part being a flexible conductive fabric, one end of the tongue part (15) being electrically connected to a steering wheel harness (2) and the other end being electrically connected to the functional part, and an easily bendable part (3) being provided at the connection point between the tongue part (15) and the functional part; The reinforcing layer 4 extends beyond the easy-to-bend portion 3, and both ends are in close contact with the surfaces of the functional portion and the tongue portion 15, respectively, and is electrically connected to the functional portion and the tongue portion 15, respectively.

[0021] Specifically, the arrow and C in FIG. 3 indicate the cross-sectional direction, and FIG. 5 is a cross-sectional view taken along the CC direction in FIG.

[0022] The functional cover body 1 is fitted onto the steering wheel, rotates with the steering wheel, and detects whether the hands are gripping the steering wheel, so that an electrostatic capacitance is formed inside the functional cover body 1 and it must be connected to the steering wheel harness 2. When the steering wheel is turned during driving, the steering wheel harness 2 is twisted along with the steering wheel, so that the easily bendable portion 3 is easily bent, and may rub against other portions and be twisted off.

[0023] When bending occurs, the addition of the reinforcing layer 4 increases the structural strength of the easy-to-bend portion 3, and at the same time, when the original circuit structure is interrupted, the reinforcing layer 4 can be used as a substitute for a conductor in the circuit, reducing the risk of failure of the steering wheel functional cover.

[0024] Furthermore, the tongue portion 15 is electrically connected to the steering wheel harness 2 via the welding point 14, and the reinforcing layer 4 is electrically connected to the steering wheel harness 2 via the tongue portion 15 and the welding point 14 in turn, and when the easy-to-bend portion 3 is electrically disconnected, the tongue portions 15 on both sides of the easy-to-bend portion 3 are electrically connected to the functional portion.

[0025] Furthermore, a conductive material is used for the reinforcing layer 4. For the conductive material, a hardenable liquid conductive material (conductive silver paste or graphite conductive adhesive) or a solid conductive material (conductive tape or adhesive conductive fabric) is used.

[0026] Specifically, a welding point 14 is formed between the steering wheel harness 2 and the tongue portion 15 by soldering to realize an electrical connection, and the reinforcing layer 4 electrically connects the tongue portion 15 and the functional part by adhesion or hardening.

[0027] When the conductor inside the functional cover body 1 breaks after multiple bending, the reinforcing layer 4 remains electrically connected to the steering wheel harness 2 as a conductor, thereby achieving the original function of the functional cover body 1 and greatly extending the service life of the conductive fabric.

[0028] Furthermore, an insulating layer 12 is further included which covers the tongue portion 15 and the outer surface of the reinforcing layer 4 . Specifically, the insulating layer 12 prevents a short circuit between the tongue portion 15 and the external metal member, ensuring that the functional cover body 1 can accurately detect whether the hands are gripping the steering wheel, and also prevents wear on the functional cover body 1, thereby extending its service life.

[0029] Further, referring to FIGS. 6 and 7, the functional cover main body 1 is The functional cover body 1 includes an inductive composite layer 6 that is adhered to the reinforcing layer 4 and detects whether a conductive object (the driver's hand in this embodiment) comes into contact with the functional cover body 1.

[0030] Furthermore, the inductive composite layer 6 is a guide layer 5 made of a flexible conductive fabric, the guide layer 5 being electrically connected to the steering wheel harness 2, and the reinforcing layer 4 being in close contact with one surface of the guide layer 5; and a guide layer base material 7 that is adhered to the surface of the guide layer 5 that is away from the reinforcing layer 4.

[0031] Furthermore, the functional cover body 1 is The dielectric layer substrate 7 further includes a shielding composite layer 9 that is adhered to the surface of the dielectric layer substrate 7 that is away from the dielectric layer 5 .

[0032] Furthermore, the shielding composite layer 9 is a shielding layer 8 that is adhered to the surface of the induction layer substrate 7 that is away from the induction layer 5; and a shield layer substrate 10 that is adhered to the surface of the shield layer 8 that is away from the guide layer substrate 7.

[0033] Specifically, the induction layer 5 and the induction layer substrate 7 are used in cooperation with each other to form a capacitance when the hand touches the conductive fabric, and by monitoring the change in the capacitance, it is possible to detect whether the hand touches the conductive fabric.

[0034] The shield layer 8 makes the inductive composite layer 6 less susceptible to the influence of external electromagnetic fields, improving detection accuracy.

[0035] Further, referring to FIG. The shield layer substrate 10 further includes a heating wire 11 attached to the surface away from the shield layer 8 for heating the functional cover body 1. When the hand grips the functional cover body 1, the hand is further heated.

[0036] Specifically, the heating wire 11 is sewn to the shield layer substrate 10, and the shield layer substrate 10 is attached to the shield layer 8 with double-sided tape 13. Furthermore, by passing electricity through the heating wire 11, electrical energy is converted into thermal energy.

[0037] Specifically, the induction layer 5, the induction layer substrate 7, the shielding layer 8, and the shielding layer substrate 10 are all fixed to each other with double-sided tape 13. Similarly, the insulating layer 12 and the heating wire 11 are fixed to each other with double-sided tape 13.

[0038] In this way, the steering wheel functional cover is heated, and when the hands come into contact with the steering wheel functional cover, the steering wheel functional cover is kept at a comfortable temperature, avoiding the temperature being too low and causing discomfort to the hands.

[0039] Example 2 The present invention further provides a steering wheel, The present invention includes a steering wheel body to which a functional cover for an automobile steering wheel having a tongue protection structure according to any one of the above embodiments is attached.

[0040] Specifically, referring to the technical effects of the above embodiments, after the above functional cover is installed, the risk of failure of the steering wheel functional cover can be reduced during the process of turning the steering wheel, and the service life can be extended.

[0041] The above description merely illustrates the preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the scope of the utility model involved in the present invention is not limited to the technical solution formed from the specific combination of the above technical features, but should include other technical solutions formed by any combination of the above technical features or their equivalent features, provided that it does not deviate from the concept of the utility model. For example, a technical solution formed by substituting the above features with technical features having similar functions disclosed (but not limited to) in the present invention.
