Description

Technical Field

[0001] This application relates to the field of cable design technology, and more particularly to a cable device and vehicle-mounted equipment. Background Technology

[0002] Cables are widely used in production and daily life. For example, when transferring data from a mobile phone to a computer via a wired connection, the phone needs to be connected to the computer via a data cable. Similarly, when connecting a mobile phone to a vehicle's central control screen, a signal transmission cable is needed to connect the phone to the screen.

[0003] In related technologies, cable lengths are generally fixed. For example, if a user's signal transmission cable is 1 meter long, then the signal from the mobile phone needs to be transmitted to the central control screen via this 1-meter cable. The longer the cable, the greater the signal loss during transmission. Furthermore, for example, if the connection distance between the mobile phone and the central control screen is 0.5 meters, using a 1-meter long signal transmission cable for signal transmission is not conducive to reducing cable loss.

[0047] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of this description.

[0048] Furthermore, this application is required to be understood not only through the actual terms used, but also through the meaning implied by each term.

[0049] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0050] This application provides a cable device. (See reference...) Figures 1 to 9 The cable device 100 provided in this application embodiment may include: a first cable 110, a second cable 120 and a cable storage structure 130.

[0051] refer to Figure 1 The first cable 110 has a first electrical connection contact 111 and a second electrical connection contact 112. The second cable 120 has a plurality of electrical connection contacts 121, which are spaced apart along the extension direction of the second cable 120. The first electrical connection contact 111 and the second electrical connection contact 112 are electrically connected to the second cable 120 through the electrical connection contacts 121, respectively.

[0052] The second cable 120 is stored or released by the cable storage structure 130, thereby changing the electrical connection position between at least one of the first electrical connection point 111 and the second electrical connection point 112 and the second cable 120.

[0053] In this manner, in the embodiments of this application, the first cable 110 has a first electrical connection contact 111 and a second electrical connection contact 112, which are electrically connected to the second cable 120 via electrical connection contact 121, respectively. The second cable 120 can be stored or released using the cable storage structure 130 to change the electrical connection position of at least one of the first and second electrical connection contacts 111 and 112 with the second cable 120. This allows users to adjust the electrical connection length of the cable device 100 as needed by storing and releasing the second cable 120, thereby reducing line loss and easily meeting users' different length requirements for the cable device 100.

[0054] refer to Figure 2 and Figure 3 In some embodiments, the plurality of electrical connection points 121 may include a first electrical connection point 121a, a second electrical connection point 121b, and a third electrical connection point 121c. The first electrical connection point 121a is electrically connected to the first electrical connection contact 111, and the second cable 120 is stored or released through the cable storage structure 130. The electrical connection position between the second electrical connection contact 112 and the second cable 120 changes from the location of the second electrical connection contact 121b to the location of the third electrical connection contact 121c.

[0055] Combination Figure 2 and Figure 3For example, the first cable 110 has a first electrical connection contact 111 at its first end (e.g., the left end) and a second electrical connection contact 112 at its second end (e.g., the right end). The second cable 120 has a first electrical connection contact 121a at its first end (e.g., the left end) and a second electrical connection contact 121b and a third electrical connection contact 121c spaced apart at its second end (e.g., the right end). The first electrical connection contact 121a is electrically connected to the first electrical connection contact 111.

[0056] When the second end of the second cable 120 is stored in the cable storage structure 130, the electrical connection position between the second electrical connection point 112 and the second cable 120 changes from the location of the second electrical connection contact point 121b to the location of the third electrical connection contact point 121c.

[0057] refer to Figure 2 Before the second cable 120 is stored in the cable storage structure 130, the current input from the first end of the second cable 120 can be transmitted to the second end of the second cable 120 in sequence through the first electrical connection contact 121a, the first electrical connection contact 111, the second electrical connection contact 112, the second electrical connection contact 121b and the third electrical connection contact 121c.

[0058] refer to Figure 3 After the second cable 120 is stored in the cable storage structure 130, the current input from the first end of the second cable 120 can be transmitted to the second end of the second cable 120 in sequence through the first electrical connection contact 121a, the first electrical connection contact 111, the second electrical connection contact 112 and the third electrical connection contact 121c.

[0059] Therefore, by using the cable storage structure 130 to store the second cable 120, the electrical connection length of the cable device 100 can be reduced, thereby reducing the line loss of the cable device 100.

[0060] Furthermore, it should be noted that in some other embodiments, the positions of the second electrical contact 121b and the third electrical contact 121c can be interchanged. For example, the second electrical contact 121b can be located to the right of the third electrical contact 121c. In some other embodiments, the plurality of electrical contact points 121 may also include other electrical contact points. For example, combined with... Figure 4 The portion of the third electrical contact point 121c that is away from the second electrical contact point 121b may also be provided with other electrical contact points at intervals, and / or the portion of the second electrical contact point 121b that is away from the third electrical contact point 121c may also be provided with other electrical contact points at intervals. This improves the convenience of adjusting the electrical length of the cable device 100.

[0061] refer to Figure 4 and Figure 5 In some embodiments, the plurality of electrical connection contacts 121 may include a first electrical connection contact 121a, a second electrical connection contact 121b, a third electrical connection contact 121c, and a fourth electrical connection contact 121d.

[0062] The second cable 120 is stored or released by the cable storage structure 130, and the electrical connection position between the first electrical connection point 111 and the second cable 120 changes from the position of the first electrical connection contact point 121a to the position of the fourth electrical connection contact point 121d. The electrical connection position between the second electrical connection point 112 and the second cable 120 changes from the position of the second electrical connection contact point 121b to the position of the third electrical connection contact point 121c.

[0063] Combination Figure 4 and Figure 5 For example, the first end (e.g., the left end) of the first cable 110 is provided with a first electrical connection contact 111, and the second end (e.g., the right end) is provided with a second electrical connection contact 112. The first end (e.g., the left end) of the second cable 120 is provided with a first electrical connection contact 121a and a fourth electrical connection contact 121d spaced apart, and the second end (e.g., the right end) is provided with a second electrical connection contact 121b and a third electrical connection contact 121c spaced apart.

[0064] When the second cable 120 is housed using the cable storage structure 130, the electrical connection position between the first electrical connection point 111 and the second cable 120 can be changed from the location of the first electrical connection contact point 121a to the location of the fourth electrical connection contact point 121d. Similarly, the electrical connection position between the second electrical connection point 112 and the second cable 120 can be changed from the location of the second electrical connection contact point 121b to the location of the third electrical connection contact point 121c.

[0065] refer to Figure 4 Before the second cable 120 is stored in the cable storage structure 130, the current input from the first end of the second cable 120 can be sequentially transmitted to the second end of the second cable 120 through the first electrical connection contact 121a, the fourth electrical connection contact 121d, the first electrical connection contact 111, the second electrical connection contact 112, the second electrical connection contact 121b, and the third electrical connection contact 121c.

[0066] refer to Figure 5 After the second cable 120 is stored in the cable storage structure 130, the current input from the first end of the second cable 120 can be transmitted to the second end of the second cable 120 in sequence through the fourth electrical connection contact 121d, the first electrical connection contact 111, the second electrical connection contact 112 and the third electrical connection contact 121c.

[0067] Therefore, by using the cable storage structure 130 to store the second cable 120, the electrical connection length of the cable device 100 can be reduced, thereby reducing the line loss of the cable device 100.

[0068] Furthermore, it should be noted that in some other embodiments, the positions of the first electrical contact 121a and the fourth electrical contact 121d can be interchanged. For example, the first electrical contact 121a can be located to the right of the fourth electrical contact 121d. Similarly, the positions of the second electrical contact 121b and the third electrical contact 121c can be interchanged.

[0069] In other embodiments, the plurality of electrical connection contacts 121 may also include other electrical connection contacts. For example, in combination with Figure 4 The portion of the first electrical contact 121a that is away from the fourth electrical contact 121d may also be provided with other electrical contact points at intervals, and / or, the portion of the fourth electrical contact 121d that is away from the first electrical contact 121a may also be provided with other electrical contact points at intervals. Similarly, the portion of the third electrical contact 121c that is away from the second electrical contact 121b may also be provided with other electrical contact points at intervals, and / or, the portion of the second electrical contact 121b that is away from the third electrical contact 121c may also be provided with other electrical contact points at intervals. This improves the convenience of adjusting the electrical length of the cable device 100.

[0070] refer to Figures 6 to 9 In some embodiments, the cable assembly 100 may further include an electrical connection component 140. The electrical connection component 140 is connected to at least one of a first electrical connection contact 111 and a second electrical connection contact 112, and the electrical connection component 140 is configured to abut against an electrical connection contact 121, thereby electrically connecting the first cable 110 to the second cable 120 through the electrical connection component 140.

[0071] For example, in one embodiment, the first electrical connection contact 111 is connected to the electrical connection assembly 140, and the first cable 110 is electrically connected to the second cable 120 by abutting the electrical connection assembly 140 against the electrical connection contact 121. In another embodiment, the second electrical connection contact 112 is connected to the electrical connection assembly 140, and the first cable 110 is electrically connected to the second cable 120 by abutting the electrical connection assembly 140 against the electrical connection contact 121. In yet another embodiment, the first electrical connection contact 111 and the second electrical connection contact 112 are respectively connected to two sets of electrical connection assemblies 140, and the first cable 110 is electrically connected to the second cable 120 by abutting the electrical connection assembly 140 against the electrical connection contact 121.

[0072] refer to Figures 6 to 9In some embodiments, the electrical connection assembly 140 may include an electrical connection body 141, with a first electrical connection contact 111 electrically connected to the electrical connection body 141. The surface of the electrical connection body 141 facing the electrical connection contact 121 is convex, and the surface of the electrical connection contact 121 facing the electrical connection body 141 is concave. The convex and concave surfaces match to limit the electrical connection body 141.

[0073] In this way, by using the convex surface of the electrical connector 141 to abut and limit the contact with the concave surface of the electrical contact point 121, the contact area between the electrical connector 141 and the electrical contact point 121 is increased, thereby improving the electrical connection effect between the electrical connector assembly 140 and the electrical contact point 121. Furthermore, by using the convex surface of the electrical connector 141 and the concave surface of the electrical contact point 121 to abut and limit the contact, the electrical connector assembly 140 is less likely to become misaligned with the electrical contact point 121 due to accidental misalignment, thus preventing electrical connection failure between the first electrical connector assembly 140 and the electrical contact point 121.

[0074] Optionally, in other embodiments of this application, the surface of the electrical connector 141 facing the electrical contact point 121 may also be a first plane, and the surface of the electrical contact point 121 facing the electrical connector 141 may be a second plane. In this way, the electrical connection between the electrical connector 141 and the electrical contact point 121 can be achieved by making the first plane and the second plane fit together.

[0075] In some embodiments, the second cable 120 is provided with a first groove 122 for guidance, and a plurality of electrical contact points 121 are disposed within the first groove 122. During the process of the cable storage structure 130 storing or releasing the second cable 120, the electrical connector 141 moves along the first groove 122.

[0076] Optionally, the electrical connector 141 can be a conductive ball. For example, the conductive ball is a sphere. For example, the conductive ball can also be an ellipsoid, etc. In this way, the second cable 120 can extend and retract more smoothly by the conductive ball rolling within the first groove 122. It should be noted that, for example, when the electrical connector 141 can roll, the first electrical connection point 111 of the first cable 110 can be connected to the electrical connector 141 via a brush or a structure similar to a brush.

[0077] Of course, in other embodiments of this application, the electrical connector 141 may not be irregularly shaped. For example, the electrical connector 141 may include a first part and a second part connected together, wherein the second part faces the second cable 120 and the first part faces away from the second cable 120. The first part may be a prism and the second part may be a hemisphere. Exemplarily, when the electrical connector 141 has an irregular shape, the first cable 110 may be connected to the electrical connector 141 by welding.

[0078] It should be noted that the shape of the electrical connector 141 is not limited in this embodiment, as long as it can be well electrically connected to the electrical contact point 121.

[0079] refer to Figure 6 In some embodiments, the electrical connection assembly 140 may include an electrical connector 141 and a first clamping structure 142. The electrical connector 141 is disposed at the first electrical connection contact 111 and is used to abut against the electrical connection contact 121. When the electrical connector 141 abuts against the electrical connection contact 121, the first clamping structure 142 is used to ensure that the electrical connector 141 abuts against the electrical connection contact 121. In this way, the reliability of the electrical connection between the first electrical connection contact 111 and the electrical connection contact 121 can be improved by using the first clamping structure 142 to ensure that the electrical connector 141 abuts against the electrical connection contact 121.

[0080] refer to Figure 7 In some embodiments, the first clamping structure 142 may include a first elastic element 1421. Exemplarily, the first elastic element 1421 may be a spring. One end of the first elastic element 1421 is connected to the first electrical connection contact 111, and the other end of the first elastic element 1421 is connected to the electrical connector 141 to press the electrical connector 141 against the second cable 120. In this way, the first elastic element 1421 can apply a clamping force towards the second cable 120 to the electrical connector 141, enabling the electrical connector 141 to be tightly connected to the electrical contact point 121, thereby improving the electrical connection effect between the electrical connector 141 and the electrical contact point 121.

[0081] refer to Figure 6 and Figure 7 In some embodiments, the electrical connection assembly 140 may further include a second clamping structure 143. The first clamping structure 142 and the second clamping structure 143 are respectively disposed on opposite sides of the second cable 120. The first clamping structure 142 and the second clamping structure 143 cooperate to bring the electrical connector 141 into contact with the electrical contact point 121. Thus, by using the abutting method of the first clamping structure 142 and the second clamping structure 143, the electrical connector 141 can be tightly connected to the electrical contact point 121, thereby improving the electrical connection effect between the electrical connector 141 and the electrical contact point 121.

[0082] refer to Figure 7In some embodiments, the second clamping structure 143 may include a second elastic element 1431 and an abutment 1432 connected to each other. A first groove 122 and a second groove 123 are respectively provided on opposite sides of the second cable 120. The opening of the first groove 122 faces the electrical connector 141, and a plurality of electrical contact points 121 are disposed within the first groove 122. The opening of the second groove 123 faces the abutment 1432.

[0083] During the process of the cable storage structure 130 storing or releasing the second cable 120, the electrical connector 141 moves along the first groove 122, and the abutment 1432 moves along the second groove 123. The first clamping structure 142 and the second clamping structure 143 cooperate to clamp the electrical connector 141 and the second cable 120, so that the electrical connector 141 abuts against the electrical contact point 121.

[0084] refer to Figure 8 and Figure 9 In some embodiments, the first clamping structure 142 may include a first magnetic element 1422, and the second clamping structure 143 may include a second magnetic element 1433. The first magnetic element 1422 is connected to the electrical connector 141, and the second magnetic element 1433 abuts against the second cable 120 or abuts against the second cable 120 via the abutment element 1432. The first magnetic element 1422 and the second magnetic element 1433 attract each other to clamp the electrical connector 141 and the second cable 120, so that the electrical connector 141 abuts against the electrical contact point 121.

[0085] In this way, a force can be applied to the electrical connector 141 toward the second cable 120 by magnetic adsorption connection of the first magnetic element 1422 and the second magnetic element 1433. This allows the electrical connector 141 to be tightly connected to the electrical contact point 121 of the second cable 120 when they are facing each other.

[0086] For example, one of the first magnetic element 1422 and the second magnetic element 1433 can be a magnet, and the other can be a component that can be magnetically attracted by a magnet, such as an iron block. Alternatively, both the first magnetic element 1422 and the second magnetic element 1433 can be magnets.

[0087] The above mainly describes the situation where the electrical connection component 140 is connected to the first electrical connection contact 111. It can be understood that in the embodiments of this application, the electrical connection component 140 can also be connected to the second electrical connection contact 112.

[0088] In some embodiments, the electrical connection assembly 140 may include an electrical connector 141 and a first clamping structure 142. The electrical connector 141 is disposed at the second electrical connection contact 112 and is used to abut against the electrical connection contact 121. When the electrical connector 141 abuts against the electrical connection contact 121, the first clamping structure 142 is used to ensure that the electrical connector 141 abuts against the electrical connection contact 121. In this way, the reliability of the electrical connection between the second electrical connection contact 112 and the electrical connection contact 121 can be improved by using the first clamping structure 142 to ensure that the electrical connector 141 abuts against the electrical connection contact 121.

[0089] In some embodiments, the first clamping structure 142 may include a first elastic element 1421. One end of the first elastic element 1421 is connected to the second electrical connection contact 112, and the other end of the first elastic element 1421 is connected to the electrical connector 141 to press the electrical connector 141 against the second cable 120. In this way, the first elastic element 1421 can apply a clamping force towards the second cable 120 to the electrical connector 141, enabling the electrical connector 141 to be tightly connected to the electrical connection contact 121, thereby improving the electrical connection effect between the electrical connector 141 and the electrical connection contact 121.

[0090] In some embodiments, the electrical connection assembly 140 may further include a second clamping structure 143. The first clamping structure 142 and the second clamping structure 143 are respectively disposed on opposite sides of the second cable 120, and the first clamping structure 142 and the second clamping structure 143 cooperate to make the electrical connector 141 abut against the electrical contact point 121.

[0091] In some embodiments, the second clamping structure 143 may include a second elastic element 1431 and an abutment 1432 connected to each other. A first groove 122 and a second groove 123 are respectively provided on opposite sides of the second cable 120. The opening of the first groove 122 faces the electrical connector 141, and a plurality of electrical contact points 121 are disposed within the first groove 122. The opening of the second groove 123 faces the abutment 1432.

[0092] During the process of the cable storage structure 130 storing or releasing the second cable 120, the electrical connector 141 moves along the first groove 122, and the abutment 1432 moves along the second groove 123. The first clamping structure 142 and the second clamping structure 143 cooperate to clamp the electrical connector 141 and the second cable 120, so that the electrical connector 141 abuts against the electrical contact point 121.

[0093] In some embodiments, the first clamping structure 142 may include a first magnetic element 1422, and the second clamping structure 143 may include a second magnetic element 1433. The first magnetic element 1422 is connected to the electrical connector 141, and the second magnetic element 1433 abuts against the second cable 120 or abuts against the second cable 120 via the abutment element 1432. The first magnetic element 1422 and the second magnetic element 1433 attract each other to clamp the electrical connector 141 and the second cable 120, so that the electrical connector 141 abuts against the electrical contact point 121.

[0094] For example, in some embodiments, the first cable 110 may include two wires, and the second cable 120 may include two wires. Correspondingly, when the cable device 100 includes an electrical connection assembly 140, the number of electrical connectors 141 can be two, and the two electrical connectors 141 can be used to connect the wires in the first cable 110 to the corresponding two wires in the second cable 120. Of course, in other embodiments of this application, the first cable 110 may also include one wire or other numbers of wires, and the second cable 120 may also include one wire or other numbers of wires. Therefore, the number of electrical connectors 141 in the electrical connection assembly 140 can be flexibly adjusted according to the number of wires included in the first cable 110 and the second cable 120.

[0095] In some embodiments, the conductors of the second cable 120 are covered with an insulating material layer. Perforations can be made in the insulating material layer as needed to expose the conductor material from the perforations, and thus, a portion of the exposed conductor material can serve as an electrical contact point 121.

[0096] refer to Figure 1 In some embodiments, the cable storage structure 130 may include a reel 131 on which the second cable 120 is wound. The reel 131 is rotated to store or release the second cable 120. The reel 131 stops rotating when the first electrical connection contact 111 and the second electrical connection contact 112 are electrically connected to the electrical connection contact 121, respectively.

[0097] Exemplarily, in an embodiment of this application, the cable storage structure 130 may further include a retraction spring, which can be used to wind the second cable 120 into the cable storage structure 130. The cable storage structure 130 may also include a ratchet mechanism. When the second cable 120 is pulled out, the ratchet mechanism allows the second cable 120 to extend normally. After the tension is removed, the second cable 120 can retract under the action of the retraction spring. At this time, the ratchet mechanism can be used to prevent the second cable 120 from retracting. This allows the cable storage structure 130 to switch to a stopped state. Furthermore, when it is necessary to retract the second cable 120, the pawl of the ratchet mechanism can be displaced from the ratchet, which can release the pawl from blocking the ratchet, thereby allowing the second cable 120 to be wound around the cable storage structure 130 under the action of the retraction spring.

[0098] refer to Figure 1 In embodiments of this application, the cable storage structure 130 may further include a housing 132, and the first cable 110 may be disposed in the housing 132. For example, the first cable 110 may be formed inside the housing 132 by injection molding. For example, the first cable 110 may be fixed to the inner wall of the housing 132. A reel 131 may be disposed in the receiving cavity of the housing 132.

[0099] In the embodiments of this application, the cable storage structure 130 can also be configured using the cable winding structure of a retractable data cable in the related art. Further details will not be provided here.

[0100] In some embodiments, when the electrical connection point 121 includes a first electrical connection point 121a, a second electrical connection point 121b, and a third electrical connection point 121c, and the second cable 120 is stored or released by the cable storage structure 130, and the electrical connection position between the second electrical connection point 112 and the second cable 120 changes from the location of the second electrical connection point 121b to the location of the third electrical connection point 121c, that is, when the end of the cable device 100 near the third electrical connection point 121c can be wound up, for example, the second cable 120 can be extended from the cable storage structure 130 by pulling the end of the second cable 120 near the third electrical connection point 121c.

[0101] In some embodiments, when the electrical connection point 121 includes a first electrical connection point 121a, a second electrical connection point 121b, a third electrical connection point 121c, and a fourth electrical connection point 121d, and the second cable 120 is stored or released by the cable storage structure 130, the electrical connection position between the first electrical connection point 111 and the second cable 120 changes from the position of the first electrical connection point 121a to the position of the fourth electrical connection point 121d; and the electrical connection position between the second electrical connection point 112 and the second cable 120 changes from the position of the second electrical connection point 121b to the position of the third electrical connection point 121c, that is, when both ends of the cable device 100 can be wound up, the second cable 120 can be extended from the cable storage structure 130 by pulling both ends of the second cable 120.

[0102] To enable those skilled in the art to more intuitively understand the solutions provided in the embodiments of this application, more detailed examples are provided below for their reference.

[0103] In one embodiment of this application, the first cable 110 is embedded within the housing 132 of the cable storage structure 130. The first end of the second cable 120 can be connected to a USB plug, and the second end can be connected to a Type-C plug. The second cable 120 can be a flat cable, and its insulation layer has multiple perforations spaced apart, allowing the conductor layer of the second cable 120 to be exposed on its outer surface. Furthermore, the conductor portion exposed on the outer surface of the second cable 120 forms an electrical contact point 121.

[0104] The end of the first cable 110 is connected to the electrical connection assembly 140. The electrical connection assembly 140 includes an electrical connector 141 (e.g., a conductive ball), a first clamping structure 142, and a second clamping structure 143. The second cable 120 has a first groove 122 along its own extension direction. The electrical connector 141 moves relative to the second cable 120 under the guidance of the first groove 122, so that the electrical connector 141 can abut against each electrical contact point 121 respectively.

[0105] The cable storage structure 130 has a hovering function. For example, when the second cable 120 is hovering in the first position, the first cable 110 abuts against the first electrical contact point of the second cable 120 via the electrical connector 141. The first clamping structure 142 and the second clamping structure 143 allow the electrical connector 141 to clamp the second cable 120, preventing misalignment between the electrical connector 141 and the first electrical contact point.

[0106] With the second cable 120 suspended in the second position, the first cable 110 abuts against the second cable 120 at electrical contact point 2 via electrical connector 141. The first clamping structure 142 and the second clamping structure 143 allow the electrical connector 141 to clamp the second cable 120 to prevent misalignment between the electrical connector 141 and electrical contact point 2.

[0107] Furthermore, the second cable 120 may also be provided with electrical connection contact points No. 3 and No. 4 at intervals. The electrical connection length of the cable device 100 can be adjusted by connecting the first cable 110 to different electrical connection contact points 121 respectively, so as to reduce the line loss of the cable device 100.

[0108] This application provides an in-vehicle device. The in-vehicle device provided in this application may include any of the cable devices 100 provided in this application. Exemplarily, the in-vehicle device may also include a vehicle's infotainment system. For example, a vehicle's infotainment system may include a central control screen.

[0109] For example, when a user connects an electronic device such as a mobile phone to the vehicle's infotainment system, the cable device 100 can be used to electrically connect the electronic device to the system. It should be noted that using a fixed cable length solution in related technologies, if the original factory cable of the infotainment system is short, the user needs to purchase an extension cable to extend it. Adding an extension cable can easily cause abnormal interruptions in the connection between the electronic device and the infotainment system. For example, if the connection between the electronic device and the infotainment system fails when the user is navigating through a fork in the road, the user will not be able to accurately obtain navigation information. However, the solution provided in this application allows the electrical connection length of the cable device 100 to be adjusted as needed, which can reduce cable loss and decrease the likelihood of abnormal interruptions in the connection between the electronic device and the infotainment system.

[0110] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0111] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of this application, the scope of which is defined by the appended claims and their equivalents.
