Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a signal line structure and a vehicle. Background Technology

[0002] In vehicle electronic systems, in-vehicle SerDes technology is widely used for high-speed data transmission to support advanced functions such as high-definition cameras, radar, lidar, and in-vehicle infotainment systems. SerDes technology reduces the number and complexity of wiring harnesses and improves system reliability and flexibility by converting parallel data into serial data for transmission.

[0003] In the signal cable structure of automotive SerDes, coaxial cable or twisted-pair cable is typically used for signal transmission. Coaxial cable has good shielding performance, effectively suppressing electromagnetic interference and is suitable for high-frequency signal transmission. Twisted-pair cable reduces electromagnetic radiation and external interference through its twisted-pair structure and is suitable for short- to medium-distance signal transmission. However, both coaxial cable and twisted-pair cable face the problem of electrostatic discharge in practical applications. Utility Model Content

[0004] To address the aforementioned shortcomings in the prior art, this utility model provides a signal line structure and vehicle capable of releasing static electricity from the transmission signal line.

[0005] To address the aforementioned technical problems, in a first aspect, this utility model provides a signal line structure, comprising:

[0006] Transmission signal lines;

[0007] An electrostatic discharge ground wire is coupled to the transmission signal line to release static electricity from the transmission signal line.

[0008] A connection structure is provided, which is connected to the electrostatic discharge ground wire and is also used to connect to the vehicle frame.

[0009] In one possible implementation, the connection structure includes an elastic element connected to the electrostatic discharge ground wire, the elastic element being elastically snapped into a snap-fit ​​groove in the frame.

[0010] In one possible implementation, the elastic element includes a connecting portion and a mounting portion that are interconnected, forming a deformation space between the connecting portion and the mounting portion. The connecting portion is connected to the electrostatic discharge ground wire, and the mounting portion is used to abut against a snap-fit ​​groove of the frame.

[0011] In one possible implementation, the mounting portion is an arc-shaped spring, and the connecting portion is connected to the edge of the mounting portion.

[0012] In one possible implementation, the elastic element comprises two elements, with the mounting portions of the two elastic elements connected to the surfaces of the surfaces away from the deformation space, and a gap existing between the mounting portions and the connecting portions; or,

[0013] The connection between the two elastic elements is a surface connection away from the deformation space.

[0014] In one possible implementation, the connecting portion is bent to form a slot, and the electrostatic discharge ground wire is secured within the slot; or...

[0015] The electrostatic discharge ground wire is disposed on the side of the connection part away from the deformation space. The connection part has a locking hole. The connection structure also includes a locking pin. The locking pin passes through the locking hole and is connected to the frame to press the electrostatic discharge ground wire tightly to the frame.

[0016] In one possible implementation, the connection structure includes a conductive sleeve formed at either end of the electrostatic discharge ground wire, the conductive sleeve being used for bolting to an assembly portion of the frame.

[0017] In one possible implementation, the transmission signal line is a twisted pair structure;

[0018] The electrostatic discharge ground wire and the transmission signal line form a twisted-triangle structure; or...

[0019] The electrostatic discharge ground wire is located outside the transmission signal line and extends along the extension direction of the transmission signal line.

[0020] In one possible implementation, along the extension direction of the transmission signal line, the length of the electrostatic discharge ground wire is equal to the length of the transmission signal line, or the length of the electrostatic discharge ground wire is less than the length of the transmission signal line, and one end of the electrostatic discharge ground wire is located close to either end of the transmission signal line.

[0021] Secondly, this utility model embodiment also provides a vehicle, including:

[0022] The frame is provided with snap-fit ​​slots and assembly parts.

[0023] The signal line structure described in the first aspect is disposed on the vehicle frame;

[0024] When the connection structure of the signal line structure includes an elastic element, the elastic element includes a connecting part and a mounting part that are interconnected. The connecting part is connected to the electrostatic discharge ground wire, and the mounting part is engaged with the snap-fit ​​slot; or,

[0025] When the connection structure of the signal line structure includes a conductive sleeve, the conductive sleeve is bolted to the assembly part.

[0026] Compared with the prior art, this application has at least the following beneficial effects:

[0027] Because the electrostatic discharge ground wire is coupled to the transmission signal line, and the connection structure is connected to both the electrostatic discharge ground wire and the vehicle frame, when there is static electricity on the transmission signal line, the static electricity on the transmission signal line can be coupled to the electrostatic discharge ground wire through the distributed capacitance, and then the electrostatic discharge ground wire will transfer the static electricity to the vehicle frame. Since the vehicle frame is in contact with the ground, the static electricity can be transferred to the ground through the vehicle frame, thereby realizing the electrostatic discharge on the transmission signal line. In addition, compared to the path of electrostatic discharge from the serializer end to the deserializer end, by setting the electrostatic discharge ground wire coupled to the transmission signal line, the static electricity on the transmission signal line can be directly coupled to the electrostatic discharge ground wire, thereby shortening the electrostatic discharge path and ensuring the lowest impedance.

[0028] In addition, compared to directly welding the electrostatic discharge ground wire to the frame, connecting the electrostatic discharge ground wire and the frame through a connecting structure can improve the selectivity of the connection between the electrostatic discharge ground wire and the frame and the reliability of the electrostatic discharge path. For example, the electrostatic discharge ground wire can be sleeved to the frame or snapped to the frame through the connecting structure. On the other hand, it can avoid damage to the frame when removing the electrostatic discharge ground wire. Attached Figure Description

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0053] In this invention, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0054] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0055] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0056] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0057] As described in the background section of this application, in related technologies, in vehicle electronic systems, in-vehicle SerDes technology is widely used for high-speed data transmission to support advanced functions such as high-definition cameras, radar, lidar, and in-vehicle infotainment systems. SerDes is short for Serializer / DeSerializer, which converts multiple low-speed parallel signals into high-speed serial signals at the transmitting end. After transmission through a medium (optical fiber or copper wire), the high-speed serial signals are finally converted back into low-speed parallel signals at the receiving end. Therefore, SerDes technology fully utilizes the channel capacity of the transmission medium, reduces the required transmission channels and the number of pins on devices, and increases signal transmission speed, thereby significantly reducing communication costs.

[0058] In the signal cable structure of automotive SerDes, coaxial cable or twisted-pair cable is typically used for signal transmission. Coaxial cable has good shielding performance, effectively suppressing electromagnetic interference (EMI) and is suitable for high-frequency signal transmission. Twisted-pair cable reduces electromagnetic radiation and external interference through its twisted-pair structure and is suitable for short to medium-distance signal transmission. However, both coaxial cable and twisted-pair cable face the problem of electrostatic discharge (ESD) in practical applications.

[0059] Electrostatic discharge refers to the phenomenon of charge transfer between two objects with different electrostatic potentials. In a vehicle environment, the instantaneous high voltage and large current generated by electrostatic discharge may damage sensitive electronic components in the vehicle's electronic system, leading to signal distortion, data loss, or even equipment failure.

[0060] Therefore, it is urgent to study electrostatic discharge on the transmission signal lines in automotive SerDes.

[0061] To address the technical problems mentioned in the background section, this utility model provides a signal line structure and a vehicle. The signal line structure includes a transmission signal line, an electrostatic discharge ground wire, and a connection structure. Since the electrostatic discharge ground wire is coupled to the transmission signal line and connected to the vehicle frame through the connection structure, the electrostatic discharge ground wire can transfer static electricity from the transmission signal line to the vehicle frame, thereby achieving the purpose of electrostatic discharge of the transmission signal line.

[0062] The present application will be described in detail below through specific embodiments:

[0063] See Figure 1This application provides a signal line structure 100, which includes a transmission signal line 110, an electrostatic discharge ground line 120, and a connection structure 130. The electrostatic discharge ground line 120 is coupled to the transmission signal line 110 to release static electricity in the transmission signal line 110. The connection structure 130 is connected to the electrostatic discharge ground line 120 and is also used to connect to the vehicle frame.

[0064] The signals transmitted by the aforementioned transmission signal line 110 include high-speed serial signals, control signals, etc. The transmission signal line 110 can be a coaxial cable structure or a twisted pair structure. In addition, the transmission signal line 110 is connected between the serializer and the deserializer.

[0065] The aforementioned transmission signal line 110 and electrostatic discharge ground line 120 both include conductive wires and an insulating layer wrapped around the outer periphery of the conductive wires. The coupling connection between the electrostatic discharge ground line 120 and the transmission signal line 110 means that a distributed capacitance will be formed between the electrostatic discharge ground line 120 and the transmission signal line 110. When electrostatic charge accumulates on the transmission signal line 110, the electrostatic charge can be coupled to the electrostatic discharge ground line 120 through the distributed capacitance and released to the ground through the ground wire connection to the vehicle frame.

[0066] The aforementioned connection structure 130 is connected to the electrostatic discharge ground wire 120. The connection structure 130 is also used to connect to the vehicle frame. It should be understood that the connection structure 130 is electrically connected to the electrostatic discharge ground wire 120 and the vehicle frame, respectively.

[0067] Based on the above embodiments, since the electrostatic discharge ground wire 120 is coupled to the transmission signal line 110, and the connection structure 130 is connected to the electrostatic discharge ground wire 120 and the frame respectively, when there is static electricity on the transmission signal line 110, the static electricity on the transmission signal line 110 can be coupled to the electrostatic discharge ground wire 120 through the distributed capacitance, and then the electrostatic discharge ground wire 120 will transfer the static electricity to the frame. Since the frame is in contact with the ground, the static electricity can be transferred to the ground through the frame, thereby realizing the electrostatic discharge on the transmission signal line 110. In addition, compared with the path of electrostatic discharge from the serializer end to the deserializer end, by setting the electrostatic discharge ground wire 120 coupled to the transmission signal line 110, the static electricity on the transmission signal line 110 can be directly coupled to the electrostatic discharge ground wire 120, thereby shortening the electrostatic discharge path and ensuring the lowest impedance.

[0068] In addition, compared to directly welding the electrostatic discharge ground wire 120 to the frame, connecting the electrostatic discharge ground wire 120 and the frame through the connecting structure 130 can improve the selectivity of the connection between the electrostatic discharge ground wire 120 and the frame and the reliability of the electrostatic discharge path. For example, the electrostatic discharge ground wire 120 can be sleeved to the frame or snapped to the frame through the connecting structure 130. On the other hand, it can avoid damage to the frame when disassembling the electrostatic discharge ground wire 120.

[0069] For example, the above-mentioned signal line structure 100 is generally used in serializer components such as cameras and radars to improve the reliability of image quality.

[0070] In some possible embodiments, see Figure 2 and Figure 3 The connection structure 130 includes an elastic element 131, which is connected to the static discharge ground wire 120. The elastic element 131 is used to elastically snap into the snap-fit ​​groove 211 of the frame.

[0071] Among them, the aforementioned elastic element 131 includes, but is not limited to, metal springs, elastic telescopic rods, etc.

[0072] Based on the above embodiments, when the elastic member 131 connected to the electrostatic discharge ground wire 120 is installed in the snap-fit ​​groove 211, pressure is applied to the elastic member 131 to cause it to contract so that it can extend into the snap-fit ​​groove 211. When the elastic member 131 extends into the snap-fit ​​groove 211, the pressure applied to the elastic member 131 is removed, thereby causing the elastic member 131 to reset and snap into the snap-fit ​​groove 211, thus fixing the electrostatic discharge ground wire 120 relative to the frame, thereby completing the connection between the electrostatic discharge ground wire 120 and the frame. The structure is simple and easy to operate.

[0073] In some possible embodiments, see Figure 2 and Figure 3 The elastic member 131 includes a connecting part 1311 and a mounting part 1312 that are connected to each other. A deformation space 131a is formed between the connecting part 1311 and the mounting part 1312. The connecting part 1311 is connected to the static discharge ground wire 120, and the mounting part 1312 is used to abut against the snap-fit ​​groove 211 of the frame.

[0074] Since a deformation space 131a is formed between the connecting part 1311 and the mounting part 1312, the connecting part 1311 is connected to the electrostatic discharge ground wire 120, and the mounting part 1312 is used to abut against the snap-fit ​​groove 211 of the frame, when the elastic member 131 is installed in the snap-fit ​​groove 211, pressure is first applied to the mounting part 1312 to deform the mounting part 1312 toward the deformation space 131a, so that the deformation space 131a shrinks, so that the elastic member 131 can extend into the snap-fit ​​groove 211. When the elastic member 131 extends into the snap-fit ​​groove 211 and the pressure applied to the mounting part 1312 is removed, the deformation space 131a can push the mounting part 1312 to abut against the snap-fit ​​groove 211 when it resets. It can be seen that by changing the deformation size of the deformation space 131a, the elastic member 131 can be installed in the snap-fit ​​groove 211. The structure is simple and easy to operate.

[0075] In some possible embodiments, see Figure 3 The mounting part 1312 is an arc-shaped spring piece, and the connecting part 1311 is connected to the edge of the mounting part 1312.

[0076] The connecting portion 1311 can be a sheet-like structure, a strip-like structure, etc. When the connecting portion 1311 is a sheet-like structure, at least a portion of the connecting portion 1311 extends in a direction away from the deformation space 131a.

[0077] Since the connecting part 1311 is connected to the edge of the mounting part 1312, the deformation range of the mounting part 1312 can be ensured.

[0078] Additionally, the elastic element 131 can be one or two. When the frame's locking slot 211 is narrow and can accommodate one elastic element 131, see [reference needed]. Figure 2 The mounting portion 1312 of the elastic member 131 abuts against the groove wall of the snap-fit ​​groove 211, and the connecting portion 1311 can also abut against the groove wall of the snap-fit ​​groove 211. In this way, the installation difficulty of the elastic member 131 can be reduced while reducing costs.

[0079] When the elastic element 131 includes two, see some possible embodiments. Figure 4 The mounting portions 1312 of the two elastic members 131 are connected to the surfaces away from the deformation space 131a, and there is a gap between the mounting portions 1312 and the connecting portions 1311.

[0080] Optionally, the mounting portion 1312 is an arc-shaped spring piece. The mounting portion 1312 has an inner surface and an outer surface facing away from each other. The inner surface is located inside the deformation space 131a, and the outer surface is located outside the deformation space 131a. The arc-shaped mounting portion 1312 protrudes in the direction from the inner surface to the outer surface.

[0081] Of course, the mounting part 1312 can also be an isosceles trapezoidal spring, a triangular spring, or other shapes.

[0082] The surface connection of the mounting portion 1312 of the two elastic members 131 away from the deformation space 131a refers to the connection of the outer surfaces of the mounting portion 1312 of the two elastic members 131, and the connection of the outer surfaces of the two mounting portions 1312 includes, but is not limited to, welding connection, adhesive connection, etc. of the outer surfaces of the two mounting portions 1312.

[0083] When the width of the snap-fit ​​groove 211 on the frame is narrow and it is difficult to accommodate a whole elastic member 131, the structure of two elastic members 131 in the above embodiment can be adopted. That is, the mounting portions 1312 of the two elastic members 131 are connected to the surfaces away from the deformation space 131a. There is a gap between the mounting portions 1312 and the connecting portions 1311. Thus, the end of the mounting portion 1312 of one elastic member 131 that is not connected to the connecting portion 1311 can be inserted into the snap-fit ​​groove 211 first. At the same time, the elastic member 131 is rotated so that more of the mounting portions 1312 are inserted into the snap-fit ​​groove 211. Then, the end of the mounting portion 1312 of the other elastic member 131 that is not connected to the connecting portion 1311 is inserted into the snap-fit ​​groove 211. Similarly, the mounting portion 1312 of the elastic member 131 is rotated. Finally, the surfaces of the mounting portions 1312 of the two elastic members 131 that are away from the deformation gap are fixedly connected.

[0084] Since the mounting portions 1312 of the two elastic members 131 are both arc-shaped spring pieces, the thickness of the part where the mounting portions 1312 of the two elastic members 131 are connected is the smallest, that is, the gap between the inner surfaces of the two mounting portions 1312 is the smallest, and the distance between the inner surfaces of the two mounting portions 1312 away from the connection point of the two mounting portions 1312 increases. In this way, the rotation of the two elastic members 131 relative to the snap-fit ​​groove 211 can be restricted, thereby fixing the two elastic members 131 in the snap-fit ​​groove 211.

[0085] In some other possible embodiments, see Figure 5 The connection portion 1311 of the two elastic members 131 is connected to the surface away from the deformation space 131a.

[0086] When the width of the snap-fit ​​groove 211 is large, the connecting portion 1311 of the two elastic members 131 in the above embodiment can be connected to the surface away from the deformation space 131a. In this way, the total deformation range of the mounting portion 1312 of the two elastic members 131 is greater than the deformation range of the mounting portion 1312 of one elastic member 131, thereby reducing the installation difficulty of the two elastic members 131 in the snap-fit ​​groove 211.

[0087] When the connection structure 130 of the two elastic members 131 in the above embodiment is installed in the snap-fit ​​groove 211, the connection part 1311 of the two elastic members 131 is first fixedly connected, and then the two elastic members 131 that are fixedly connected to the connection part 1311 are elastically snapped into the snap-fit ​​groove 211.

[0088] Furthermore, the connection structure 130 between the elastic element 131 and the static discharge ground wire 120 includes, but is not limited to, snap-fit ​​connection, welding connection, adhesive connection, etc. Figure 6 and Figure 7 .

[0089] When the elastic element 131 is connected to the static discharge ground wire 120 via a snap-fit ​​connection, in some possible embodiments, see [link to relevant documentation]. Figure 8 and Figure 9 The connecting part 1311 is bent to form a slot 1313, and the electrostatic discharge ground wire 120 is inserted into the slot 1313.

[0090] Optionally, a portion of the connecting portion 1311 extends in a direction away from the deformation space 131a, and a slot 1313 is formed at the end of the connecting portion 1311 away from the deformation space 131a.

[0091] Optionally, the connecting part 1311 includes two independent parts. One part of the connecting part 1311 is connected to one side edge of the mounting part 1312, and the other part of the connecting part 1311 is connected to the other side edge of the mounting part 1312. The ends of the two independent connecting parts 1311 away from the mounting part 1312 are bent to form a slot 1313. In this way, the two slots 1313 can engage the end of the electrostatic discharge ground wire 120.

[0092] Based on the above embodiments, by bending the connecting portion 1311 to form a slot 1313 to engage the electrostatic discharge ground wire 120, the difficulty of installing the electrostatic discharge ground wire 120 on the elastic member 131 can be reduced.

[0093] In some other possible embodiments, see Figure 10 The electrostatic discharge ground wire 120 is located on the side of the connection part 1311 away from the deformation space. The connection part 1311 has a locking hole. The connection structure 130 also includes a locking pin 132. The locking pin 132 passes through the locking hole and is connected to the frame to press the electrostatic discharge ground wire 120 to the frame, thereby improving the reliability of the installation of the electrostatic discharge ground wire 120.

[0094] It should be noted that in both the above-mentioned electrostatic discharge ground wire 120 being snapped into the slot 1313, or the electrostatic discharge ground wire 120 being disposed on the side of the connecting part 1311 away from the deformation space 131a and pressed into the frame by the clip 132, the electrostatic discharge ground wire 120 is electrically connected to the connecting part 1311 in order to ensure the release of static electricity.

[0095] The above describes an embodiment in which the connecting structure 130 includes an elastic member 131. The following describes the connecting structure 130 including a conductive sleeve. In some possible embodiments, the conductive sleeve is formed at either end of the electrostatic discharge ground wire 120. The conductive sleeve is used to bolt to the assembly part of the frame.

[0096] Specifically, the insulation layer at either end of the electrostatic discharge ground wire 120 is removed to expose the conductive wire, thereby forming a conductive loop on the conductive wire for bolting to the assembly part on the frame.

[0097] This avoids the need to design the mounting position of the connecting structure 130 on the frame, thus simplifying the frame manufacturing process.

[0098] In some possible embodiments, see Figure 11 and Figure 13 The transmission signal line 110 is a twisted pair; the electrostatic discharge ground wire 120 forms a twisted three with the transmission signal line 110; or, see [link to relevant documentation]. Figure 12 and Figure 14 The electrostatic discharge ground wire 120 is located outside the transmission signal line 110 and extends along the extension direction of the transmission signal line 110.

[0099] Based on the above embodiments, compared to placing a metal cylinder on the transmission signal line 110 to release static electricity, this embodiment can reduce the weight of the signal line structure 100 while reducing costs.

[0100] In some possible embodiments, see Figure 11 and Figure 12 Along the extension direction of the transmission signal line 110, the length of the electrostatic discharge ground wire 120 is equal to the length of the transmission signal line 110, or, see... Figure 13 and Figure 14 The length of the electrostatic discharge ground wire 120 is less than the length of the transmission signal line 110, and one end of the electrostatic discharge ground wire 120 is set close to either end of the transmission signal line 110.

[0101] The aforementioned extension direction refers to the overall direction of the transmission signal line 110, for example, such as... Figure 11 As shown, the transmission signal line 110 extends in the direction indicated by the X arrow.

[0102] The statement that the length of the electrostatic discharge ground wire 120 is equal to the length of the transmission signal line 110 means that the two ends of the electrostatic discharge ground wire 120 are flush with or approximately flush with the two ends of the transmission signal line 110.

[0103] The length of the electrostatic discharge ground wire 120 is less than the length of the transmission signal line 110, and the fact that one end of the electrostatic discharge ground wire 120 is close to any end of the transmission signal line 110 means that any end of the electrostatic discharge ground wire 120, which is shorter than the transmission signal line 110, is flush or approximately flush with the end of the transmission signal line 110, and the other end is connected to the vehicle frame through the connection structure 130.

[0104] Therefore, when the length of the electrostatic discharge ground wire 120 is equal to the length of the transmission signal line 110 along the extension direction of the transmission signal line 110, the electrostatic discharge path can be greatly shortened and the electrostatic discharge effect can be improved. When the length of the electrostatic discharge ground wire 120 is less than the length of the transmission signal line 110 along the extension direction of the transmission signal line 110, the cost and weight of the signal line structure 100 can be reduced while ensuring the electrostatic discharge effect.

[0105] Optionally, when the length of the electrostatic discharge ground wire 120 is less than the length of the transmission signal line 110 along the extension direction of the transmission signal line 110, one end of the electrostatic discharge ground wire 120 is positioned close to the serializer.

[0106] See Figure 15 This application also provides a vehicle 200, which includes a frame 210 and a signal line structure 100 as described in the above embodiments. The frame 210 is provided with a snap-fit ​​groove 211 and an assembly part. The signal line structure 100 is disposed on the frame 210.
