[0001] This application belongs to the field of automotive conductive component technology, and more specifically, relates to a vehicle dashboard grounding device and a vehicle. Background Technology

[0002] Grounding refers to connecting the negative terminal of an automotive electrical device to a metal component of the vehicle body to form a complete circuit. In automobiles, the grounding harness is part of the automotive electrical circuit, and the quality of the grounding of the vehicle body grounding wires is crucial to the proper functioning of the automotive electronic control system and electrical devices.

[0003] In traditional technology, to ground the dashboard, the dashboard wiring harness can be directly grounded to the vehicle body. However, the required dashboard grounding wiring harness is long, the manufacturing cost is high, and the conductivity between the dashboard wiring harness and the whole vehicle is poor, which can easily affect the stability and safety of the vehicle's electrical system. Utility Model Content

[0004] The purpose of this application is to provide a vehicle dashboard grounding device and a vehicle, which aims to solve the technical problems of long grounding wire harnesses between the traditional dashboard and the vehicle body, high manufacturing costs, and poor conductivity.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, a vehicle dashboard grounding device is provided, comprising: The first connecting plate has a first connecting surface and a second connecting surface arranged opposite to each other, and the first connecting surface is used to be attached and fixed to the vehicle body; The second connecting plate is disposed on one side of the second connecting surface and is fixed to the first connecting plate; the second connecting plate has a third connecting surface and a fourth connecting surface disposed opposite to each other, the third connecting surface being used to be attached to and fixed on the instrument tube beam; The instrument tube beam is used to ground the instrument panel wiring harness, and both the first connecting plate and the second connecting plate are conductive sheets to achieve electrical conductivity between the instrument panel wiring harness and the vehicle body.

[0006] Compared with the prior art, the vehicle dashboard grounding device provided in this application forms an integral conductive sheet through the first connecting plate and the second connecting plate, and the integral conductive sheet structure achieves conductivity between the instrument beam tube through the third connecting surface. Combined with the grounding between the instrument panel wiring harness and the instrument beam tube, conductivity between the instrument panel wiring harness and the vehicle body can be achieved. The design of the conductive sheets in the first and second connecting plates ensures good conductivity between the instrument tube beam and the vehicle body, and the conductive sheet structure can effectively improve the stability and durability of the electrical connection. Therefore, the vehicle dashboard grounding device provided in this application can effectively save long-distance grounding wiring harnesses, reduce manufacturing costs, and improve the economic applicability of conductive connections between the dashboard wiring harness and the vehicle body; furthermore, it can effectively improve the conductivity between the dashboard wiring harness and the vehicle body, and has high stability and durability, which is beneficial to optimizing the electrical system performance of the dashboard.

[0007] In conjunction with the first aspect, in one possible implementation, the second connecting surface is provided with a first grounding bolt, and the fourth connecting surface is provided with a second grounding bolt; The first grounding bolt passes through the first connecting plate and is fixedly connected to the vehicle body; the second grounding bolt passes through the second connecting plate and is fixedly connected to the instrument tube beam.

[0008] By setting the first ground bolt, the first connecting plate and the vehicle body are fixed together without affecting the electrical conductivity between them. Similarly, by setting the second ground bolt, the second connecting plate and the instrument tube beam are fixed together without affecting the electrical conductivity between them.

[0009] In some embodiments, the first grounding bolt and the second grounding bolt are staggered.

[0010] By staggering the first and second grounding bolts, misalignment during installation can be avoided, ensuring ease of installation and fixing.

[0011] For example, the first connecting plate and the second connecting plate are an integral structure.

[0012] By setting the first connecting plate and the second connecting plate as an integral structure, it is convenient to process and produce the first connecting plate and the second connecting plate at the same time, and eliminates the step of fixing the first connecting plate and the second connecting plate to each other, thereby improving the efficiency of connection and assembly.

[0013] In some embodiments, the first connecting plate has a first direction and a second direction that are perpendicular to each other; in the first direction, the first connecting plate extends through the second connecting plate; The first connecting plate is bent at one end in the second direction to form the second connecting plate; The first grounding bolt is located on the portion of the first connecting plate that extends over the second connecting plate, so that the second grounding bolt is misaligned with the first grounding bolt in the first direction.

[0014] By extending the first connecting plate over the second connecting plate, the second connecting plate and the first grounding bolt are respectively located at opposite ends in the first direction, thereby achieving a staggered arrangement of the first grounding bolt and the second grounding bolt after the second grounding bolt is installed.

[0015] In some embodiments, the portion of the first connecting plate extending over the second connecting plate is provided with a clearance opening, which is recessed inward along the second direction from the bending side of the first connecting plate and close to the bending portion of the second connecting plate.

[0016] By setting a clearance opening, the resistance during the bending process can be reduced when forming the second connecting plate, facilitating the rapid forming of the second connecting plate; at the same time, it can alleviate the problem of stress concentration at the bending point and ensure the stability of the conductive sheet structure formed by the first connecting plate and the second connecting plate.

[0017] In conjunction with the first aspect, in one possible implementation, the vehicle dashboard grounding device further includes: A limiting structure is provided between the second connecting plate and the instrument tube beam to limit the relative position of the second connecting plate and the instrument tube beam.

[0018] By setting a limiting structure, on the one hand, the second connecting plate and the instrument tube beam can be pre-attached, improving the ease of installation; on the other hand, the effective limiting between the second connecting plate and the instrument tube beam can be achieved, avoiding the problem of poor contact and ensuring the stability and continuity of conductivity.

[0019] In some embodiments, the limiting structure includes: The first limiting block is disposed on the second connecting plate and extends toward the instrument tube beam; The first limiting hole is provided on the instrument tube beam and corresponds to and is compatible with the position of the first limiting block. When the second connecting plate is attached to the instrument tube beam, the first limiting block is inserted and limited within the first limiting hole.

[0020] The limiting function of the limiting structure is achieved through the cooperation of the first limiting block and the first limiting hole; and the first limiting hole extends into the instrument tube beam to ensure the stability of the connection between the first limiting block and the first limiting hole.

[0021] In conjunction with the first aspect, in one possible implementation, the instrument tube beam is provided with a relief groove, and a connecting lug is provided on one side wall of the relief groove, the connecting lug being arranged parallel to the second connecting plate; wherein, the first connecting plate is placed in the relief groove, and the second connecting plate is attached to and fixed on the connecting lug.

[0022] By setting a clearance groove, the first connecting plate can be easily enclosed within the clearance groove, which helps to ensure the connection stability between the instrument tube beam and the conductive sheet structure; by setting a connecting ear, and setting the connecting ear parallel to the second connecting plate, the second connecting plate can be easily connected, and the aforementioned first limiting hole can be easily set.

[0023] Secondly, embodiments of this application also provide a vehicle that includes the aforementioned vehicle dashboard grounding device.

[0024] The vehicle provided in this application, having included the aforementioned vehicle dashboard grounding device, possesses all the beneficial effects of the aforementioned vehicle dashboard grounding device. It is highly stable and durable, improves the conductivity between the instrument panel beam and the vehicle body, reduces manufacturing costs, enhances the economic applicability of the conductive connection between the instrument panel beam and the vehicle body, and is conducive to optimizing the electrical system performance of the instrument panel.

[0028] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0029] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] In addition, for ease of understanding, this application uses appendices. Figure 1 The direction indicated by the middle arrow A is used to indicate the first direction, namely the length direction of the first connecting plate 1; and an attachment is used. Figure 1 The direction indicated by the middle arrow B is used to indicate the second direction, namely the width direction of the first connecting plate 1.

[0032] It should be noted that, for ease of description, the term "grounding device" is used in this application to refer to "vehicle dashboard grounding device", and a "conductive sheet structure" is used to guide the conductive sheet formed by the first connecting plate 1 and the second connecting plate 2.

[0033] It is important to understand that excessively long grounding harnesses for dashboards not only increase the cost of raw materials but also increase the complexity and time cost of assembly, which is detrimental to the performance improvement of the electrical system. Furthermore, the grounding wires have poor performance, and the connection ends of the grounding harness are prone to loosening and instability, affecting conductivity stability and durability.

[0034] Furthermore, if there is a poor connection in the grounding wire, it's equivalent to having a resistor connected in series in the circuit, causing inaccurate sensor signals, sluggish actuator operation, and malfunction of related electronic control units, ultimately leading to vehicle malfunctions. Therefore, the grounding function plays a crucial role in the electrical system, and the condition of the three grounding wires on the vehicle body is key to the proper functioning of the vehicle's electronic control system and electrical devices.

[0035] With the rapid development of automotive electronics technology, the performance requirements of electrical systems are becoming increasingly stringent. Traditional grounding connection methods can no longer meet the needs of wire performance and cost control. Therefore, it is urgent to develop a new grounding device to achieve a conductive connection between the instrument panel and the vehicle body.

[0036] Please refer to the following: Figures 1 to 3 The following describes the vehicle dashboard grounding device and the vehicle provided in this application. The vehicle dashboard grounding device includes a first connecting plate 1 and a second connecting plate 2; the first connecting plate 1 has a first connecting surface 11 and a second connecting surface 12 arranged opposite to each other, the first connecting surface 11 being used to attach and fix it to the vehicle body 3; the second connecting plate 2 is disposed on one side of the second connecting surface 12 and fixed to the first connecting plate 1; the second connecting plate 2 has a third connecting surface 21 and a fourth connecting surface 22 arranged opposite to each other, the third connecting surface 21 being used to attach and fix it to the instrument tube beam 4; wherein, the instrument tube beam 4 is used to ground the instrument panel wiring harness, and both the first connecting plate 1 and the second connecting plate 2 are conductive sheets to achieve conductivity between the instrument panel wiring harness and the vehicle body 3.

[0037] It should be noted that the instrument panel beam 4 is a support structure under the car's instrument panel, used to fix and support the instrument panel components.

[0038] By bypassing the instrument panel wiring harness and directly grounding it to the vehicle body 3, the overall length of the grounding wiring harness becomes too long. Grounding the instrument panel wiring harness to the instrument panel beam 4 does not allow it to conduct electricity to the vehicle body 3, which is detrimental to the conductivity with the whole vehicle. However, the solution in this application is to ground the instrument panel wiring harness to the instrument panel beam 4 and then ground it to the vehicle body 3 with the help of the second connecting plate 2 and the first connecting plate 1.

[0039] Specifically, after the instrument panel wiring harness is grounded to the instrument tube beam 4, the conductive structure between the instrument tube beam 4 and the vehicle body 3 can achieve a conductive connection between the instrument panel wiring harness and the vehicle body 3. The specific conductive path is: instrument panel wiring harness, instrument tube beam 4, second connecting plate 2, first connecting plate 1 and vehicle body 3. Therefore, the conductivity between the instrument panel and the whole vehicle can be improved.

[0040] The first connecting surface 11 is attached to the vehicle body 3, which ensures that the conductive area between the first connecting plate 1 and the vehicle body 3 covers the first connecting surface 11, thereby ensuring the conductive continuity and stability between the first connecting plate 1 and the vehicle body 3; similarly, the third connecting surface 21 is attached to the instrument tube beam 4, which ensures that the conductive area between the second connecting plate 2 and the instrument tube beam 4 covers the second connecting surface 12, thereby ensuring the conductive continuity and stability between the second connecting plate 2 and the instrument tube beam 4.

[0041] Furthermore, the first connecting surface 11 is fixed to the vehicle body 3, which can ensure the connection stability between the first connecting plate 1 and the vehicle body 3; similarly, the third connecting surface 21 is fixed to the instrument tube beam 4, which can ensure the connection stability between the second connecting plate 2 and the instrument tube beam 4; thereby effectively preventing loosening and displacement of the electrical connection area.

[0042] The second connecting plate 2 is located on one side of the second connecting surface 12 and is fixed to the first connecting plate 1. On the one hand, it can adapt to the relative positional relationship between the vehicle body 3 and the instrument tube beam 4, making installation convenient; on the other hand, it can realize the conductive connection between the second connecting plate 2 and the first connecting plate 1. Since both the first connecting plate 1 and the second connecting plate 2 are conductive sheet structures, when the first connecting plate 1 and the second connecting plate 2 are connected, the conductive connection between the first connecting plate 1 and the second connecting plate 2 can be realized.

[0043] Optionally, the second connecting plate 2 extends obliquely away from the second connecting surface 12; specifically, the second connecting plate 2 is perpendicular to the first connecting plate 1, and the included angle between the first connecting plate 1 and the second connecting plate 2 is 90°; optionally, the included angle between the second connecting plate 2 and the first connecting plate 1 is an acute angle; optionally, the included angle between the second connecting plate 2 and the first connecting plate 1 is an obtuse angle; and the specific tilt angle can be selectively set according to actual needs.

[0044] It should be noted that after the second connecting plate 2 is attached to the instrument tube beam 4, it can achieve grounding, that is, the second connecting plate 2 is indirectly connected to the negative terminal of the instrument panel circuit; moreover, the grounding principle used in this application is existing technology, and will not be described in detail here.

[0045] Furthermore, the conductive sheet itself is a metal sheet that can improve electrical connection performance, and is usually made of materials with good conductivity, such as copper alloys or silver-plated materials; therefore, its conductivity is superior to that of the connecting wire harness, and thus the design of the conductive sheet itself can improve the conductivity of the grounding device. Optionally, the shapes of the first connecting plate 1 and the second connecting plate 2 can be adaptively designed according to the structure of the vehicle body 3 and the instrument tube beam 4.

[0046] Compared with the prior art, the vehicle dashboard grounding device provided in this application forms an integral conductive sheet through the first connecting plate 1 and the second connecting plate 2. The integral conductive sheet structure achieves conductivity between the instrument beam tube and the third connecting surface 21. Combined with the grounding between the instrument panel wiring harness and the instrument beam 4, conductivity between the instrument panel wiring harness and the vehicle body 3 can be achieved.

[0047] The design of the conductive plates in the first connecting plate 1 and the second connecting plate 2 ensures good conductivity between the instrument tube beam 4 and the body 3, and the conductive plate structure can effectively improve the stability and durability of the electrical connection.

[0048] Therefore, the vehicle dashboard grounding device provided in this application can effectively save long-distance grounding wiring harnesses, reduce manufacturing costs, and improve the economic applicability of the conductive connection between the dashboard wiring harness and the vehicle body 3; in addition, it can effectively improve the conductivity between the dashboard wiring harness and the vehicle body 3, and has high stability and durability, which is conducive to optimizing the electrical system performance of the dashboard.

[0049] Please see Figure 2 In some possible embodiments, a first grounding bolt 5 is provided on the second connecting surface 12, and a second grounding bolt 6 is provided on the fourth connecting surface 22; the first grounding bolt 5 passes through the first connecting plate 1 and is fixedly connected to the vehicle body 3; the second grounding bolt 6 passes through the second connecting plate 2 and is fixedly connected to the instrument tube beam 4.

[0050] Specifically, the first connecting plate 1 has a first mounting hole 14, the vehicle body 3 has a first connecting hole, and the first ground bolt 5 passes through the first mounting hole 14 and the first connecting hole and is fixed by the first nut, or screwed into the vehicle body 3. Similarly, the second connecting plate 2 has a second mounting hole 24, the instrument tube beam 4 has a second connecting hole, and the second ground bolt 6 passes through the second mounting hole 24 and the second connecting hole and is fixed by the second nut.

[0051] It should be noted that a grounding bolt is a connector specifically designed for use in electrical systems such as automobiles. Its main function is to establish a ground connection in the circuit, i.e., a grounding connection. It is typically installed in locations where grounding is required to ensure the normal operation and safety of the electrical system.

[0052] The first grounding bolt 5 and the second grounding bolt 6 in this application can be used to cooperate with the conductive sheet and connect to the metal parts of the vehicle body 3 to achieve the grounding connection of the instrument panel; this connection method ensures the stable connection between the first connecting plate 1 and the second connecting plate 2 and the vehicle body 3 and the instrument tube beam 4, thereby ensuring the stability of the conductivity and further improving the stability and safety of the vehicle electrical system.

[0053] It should be understood that by setting the first ground bolt 5 in this application, on the one hand, the first connecting plate 1 and the body 3 can be fixed, and on the other hand, the conductivity between the first connecting plate 1 and the body 3 is not affected; similarly, by setting the second ground bolt 6, on the one hand, the second connecting plate 2 and the instrument tube beam 4 can be fixed, and on the other hand, the conductivity between the second connecting plate 2 and the instrument tube beam 4 is not affected.

[0054] In addition, the first grounding bolt 5 in this application can realize the detachable connection between the first connecting plate 1 and the vehicle body 3, and the second grounding bolt 6 can realize the detachable connection between the second connecting plate 2 and the instrument tube beam 4, which facilitates inspection or repair and is beneficial to subsequent maintenance and upkeep.

[0055] It should be understood that the installation of the first grounding bolt 5 and the second grounding bolt 6 makes the entire grounding device design simple, easy to install and maintain, and effectively improves the flexibility and efficiency of the production process.

[0056] Please see Figure 2 In some embodiments, the first grounding bolt 5 and the second grounding bolt 6 are staggered.

[0057] It is important to understand that when installing the first grounding bolt 5 and the second grounding bolt 6, the nut portion of the bolt must be confined outside the first connecting plate 1 or the second connecting plate 2. Therefore, if the reserved space is insufficient, interference may easily occur when installing the first grounding bolt 5 or the second grounding bolt 6, affecting the installation efficiency and the stability of the connection.

[0058] By staggering the first grounding bolt 5 and the second grounding bolt 6, misalignment during installation can be avoided, ensuring ease of installation and fixing, making the connection more stable, and also optimizing the installation structure of the conductive sheet, thereby improving the overall reliability and conductivity of the device.

[0059] Specifically, in order to achieve the misalignment of the first grounding bolt 5 and the second grounding bolt 6, the first grounding bolt 5 and the second grounding bolt 6 can be misaligned in a first direction, or the first grounding bolt 5 and the second grounding bolt 6 can be misaligned in a second direction; the specific misalignment direction can be selectively set according to actual needs.

[0060] Please see Figure 1 For example, the first connecting plate 1 and the second connecting plate 2 are an integral structure.

[0061] By setting the first connecting plate 1 and the second connecting plate 2 as an integral structure, it is convenient to process and produce the first connecting plate 1 and the second connecting plate 2 at the same time, and eliminate the step of fixing the first connecting plate 1 and the second connecting plate 2 to each other, thereby improving the efficiency of connection and assembly.

[0062] Furthermore, the first connecting plate 1 and the second connecting plate 2 are an integral structure, which enhances the integrity and stability of the entire conductive sheet structure, reduces the risk of loosening at the connection points, and helps to improve the durability and stability of the conductivity.

[0063] Optionally, the first connecting plate 1 and the second connecting plate 2 are integral structures, and the first connecting plate 1 and the second connecting plate 2 are formed by bending.

[0064] Optionally, the first connecting plate 1 and the second connecting plate 2 are integrally cast structures.

[0065] For example, the first connecting plate 1 and the second connecting plate 2 are separate structures, and the first connecting plate 1 and the second connecting plate 2 are detachably connected.

[0066] Optionally, the first connecting plate 1 and the second connecting plate 2 partially overlap, and a third grounding bolt is provided in the overlapping area of ​​the first connecting plate 1 and the second connecting plate 2. One end of the third grounding bolt passes through the first connecting plate 1 and the second connecting plate 2 in sequence, and is fixed at the second connecting plate 2 by a nut.

[0067] Please see Figure 1 and Figure 2 In some embodiments, the first connecting plate 1 has a first direction and a second direction that are perpendicular to each other; in the first direction, the first connecting plate 1 extends through the second connecting plate 2; one end of the first connecting plate 1 in the second direction is bent to form the second connecting plate 2; the first grounding bolt 5 is provided on the portion of the first connecting plate 1 that extends through the second connecting plate 2, so that in the first direction, the second grounding bolt 6 is misaligned with the first grounding bolt 5.

[0068] It should be understood that by extending the first connecting plate 1 through the second connecting plate 2, the first grounding bolt 5 and the second grounding bolt 6 can be offset in the first direction.

[0069] The structural design of the first connecting plate 1 in a specific direction allows the first grounding bolt 5 and the second grounding bolt 6 to be staggered in the corresponding direction, which further optimizes the spatial layout of the grounding device of this application, ensures the stability of the connection and the high efficiency of conductivity, and facilitates installation and arrangement.

[0070] In this application, by extending the first connecting plate 1 through the second connecting plate 2, the second connecting plate 2 and the first grounding bolt 5 are respectively located at both ends in the first direction, thereby achieving a staggered arrangement of the first grounding bolt 5 and the second grounding bolt 6 after the second grounding bolt 6 is installed.

[0071] It should be understood that the first connecting plate 1 is bent at one end in the second direction to form the second connecting plate 2. The first connecting plate 1 and the second connecting plate 2 can be formed by bending. Furthermore, since the first connecting plate 1 extends over the second connecting plate 2, when the second connecting plate 2 is bent in the manner described above, the second grounding bolt 6 on the second connecting plate 2 will not extend to the extended end of the first connecting plate 1. At this time, after the first grounding bolt 5 is placed at the extended end of the first connecting plate 1, effective limiting can be achieved between the second grounding bolt 6 and the first grounding bolt 5.

[0072] It should be understood that, in the first direction, both the first connecting plate 1 and the second connecting plate 2 have a certain extension length; in this application, it is specified that, in the first direction, the extension of the first connecting plate 1 extends beyond the second connecting plate 2; it can be understood that the extension length of the first connecting plate 1 in the first direction is greater than the extension length of the second connecting plate 2 in the first direction.

[0073] Furthermore, the portion of the first connecting plate 1 that extends beyond the second connecting plate 2 can be understood as: in the first direction, the portion of the first connecting plate 1 that extends beyond the second connecting plate 2.

[0074] For ease of understanding, the two ends of the first connecting plate 1 along the first direction can be defined as the first end face and the second end face, respectively, and the two ends of the first connecting plate 1 along the second direction can be defined as the third end face and the fourth end face, respectively.

[0075] As one specific arrangement of the second connecting plate 2, the second connecting plate 2 is formed by bending on the fourth end face, or in other words, the bent sides of the second connecting plate 2 and the first connecting plate 1 are at the fourth end face. In this case, the first grounding bolt 5 is close to the second end, and the second grounding bolt 6 is close to the first end.

[0076] For example, as another specific arrangement of the second connecting plate 2, the second connecting plate 2 can also be bent into shape on the first end face side, or in other words, the bent sides of the second connecting plate 2 and the first connecting plate 1 are at the first end face. In this case, the first grounding bolt 5 is close to the second end, and the second grounding bolt 6 is close to the first end.

[0077] Please see Figure 1 In some embodiments, the portion of the first connecting plate 1 extending over the second connecting plate 2 is provided with a clearance opening 13. The clearance opening 13 is recessed from the bending side of the first connecting plate 1 along the second direction and is close to the bending portion of the second connecting plate 2.

[0078] By setting the clearance opening 13, the resistance during the bending process can be reduced when bending to form the second connecting plate 2, which facilitates the rapid forming of the second connecting plate 2; at the same time, it can alleviate the problem of stress concentration at the bending point and ensure the stability of the conductive sheet structure formed by the first connecting plate 1 and the second connecting plate 2.

[0079] Specifically, the clearance opening 13 is provided to penetrate the first connecting surface 11 and the second connecting surface 12 in a direction perpendicular to the surface of the first connecting plate 1, and the clearance opening 13 has an opening facing the instrument tube beam 4.

[0080] When the second connecting plate 2 is continued to bend and form, since the relief opening 13 is close to the bending side of the second connecting plate 2, the deformation resistance at the relief opening 13 can be reduced, thus facilitating the bending and forming; and the stress concentration problem of the structure formed after bending can be effectively alleviated compared with the structure without the relief opening 13.

[0081] Please see Figure 3 In some possible embodiments, the vehicle dashboard grounding device further includes a limiting structure disposed between the second connecting plate 2 and the instrument tube beam 4; the limiting structure is used to limit the relative position of the second connecting plate 2 and the instrument tube beam 4.

[0082] By setting a limiting structure, on the one hand, the second connecting plate 2 and the instrument tube beam 4 can be pre-attached, improving the ease of installation; on the other hand, the effective limiting between the second connecting plate 2 and the instrument tube beam 4 can be achieved, avoiding the problem of poor contact and ensuring the stability and continuity of conductivity.

[0083] Specifically, when installing the conductive sheet structure of the first connecting plate 1 and the second connecting plate 2, the second connecting plate 2 and the instrument tube beam 4 can be pre-attached by the limiting structure, and then the second connecting plate 2 and the instrument tube beam 4 can be effectively fixed by installing the second grounding bolt 6, and finally the first grounding bolt 5 can be fixed.

[0084] Compared to the traditional method of directly screwing the second ground bolt 6, in this application, when installing the second ground bolt 6, there is no need to manually press the position of the second connecting plate 2. The second connecting plate 2 and the instrument tube beam 4 can be limited in advance by the limiting structure.

[0085] For example, a second limiting structure is provided between the first connecting plate 1 and the vehicle body 3. The second limiting structure is used to effectively limit the distance between the first connecting plate 1 and the vehicle body 3. Specifically, the specific structure of the second limiting structure can be set with reference to the above-mentioned limiting structure.

[0086] Optionally, the number of the above-mentioned limiting structures can be selectively set according to actual needs. For conductive structures with a large overall size, two or more sets of limiting structures can be set at intervals to ensure the stability of the limiting.

[0087] Please see Figure 3 In some embodiments, the limiting structure includes a first limiting block 23 and a first limiting hole 421; the first limiting block 23 is disposed on the second connecting plate 2 and extends toward the instrument tube beam 4; the first limiting hole 421 is disposed on the instrument tube beam 4, corresponding to and adapting to the position of the first limiting block 23; wherein, when the second connecting plate 2 and the instrument tube beam 4 are in contact, the first limiting block 23 is inserted and limited within the first limiting hole 421.

[0088] In this application, the limiting function of the limiting structure is achieved through the mutual cooperation of the first limiting block 23 and the first limiting hole 421; and the first limiting hole 421 extends into the instrument tube beam 4 to ensure the stability of the connection between the first limiting block 23 and the first limiting hole 421.

[0089] Specifically, when installing the conductive sheet structure, the first limiting block 23 can be installed into the first limiting hole 421 to limit the second connecting plate 2 and the instrument tube beam 4. At this time, the second mounting hole 24 on the second connecting plate 2 can correspond to the position of the second connecting hole on the instrument tube beam 4, which can facilitate the connection of the second grounding bolt 6. After the second grounding bolt 6 is fixed, the first grounding bolt 5 is installed. This simplifies the positioning process of the second mounting hole 24 and the second connecting hole and improves the assembly efficiency.

[0090] Therefore, in this application, the pre-attachment between the second connecting plate 2 and the instrument tube beam 4 is achieved by using the first limiting block 23 and the first limiting hole 421, which can optimize the internal assembly process and improve work efficiency.

[0091] It should be noted that the positions of the first limiting block 23 and the first limiting hole 421 can be selectively set according to actual needs.

[0092] Optionally, the cross-sectional dimensions of the first limiting block 23 can be rectangular, square, circular, or triangular, and the shape of the first limiting block 23 can be selectively set according to actual needs.

[0093] Optionally, the length of the first limiting block 23 along the axial direction of the first limiting hole 421 is greater than the length of the first limiting hole 421, so as to ensure the stability of the limiting structure.

[0094] Specifically, in one embodiment of the first limiting block 23, the first limiting block 23 is a protruding structure fixed on the second connecting plate 2; in another embodiment of the first limiting block 23, it is a bent plate formed by bending on the second connecting plate 2, extending towards the second connecting plate 2, and the bent plate is located on the outer edge of the second connecting plate 2 for bending and shaping. Optionally, the second limiting block is a block-shaped or plate-shaped structure welded and fixed on the second connecting plate 2.

[0095] As another embodiment of the above-mentioned limiting structure, the first limiting hole 421 is provided on the second connecting plate 2, and the first limiting block 23 is provided on the instrument tube beam 4.

[0096] Specifically, the limiting structure includes a second limiting block and a second limiting hole; the second limiting hole is located on the second connecting plate 2; the second limiting block is located on the instrument tube beam 4 and extends towards the second connecting plate 2; the second limiting hole corresponds to and is compatible with the first limiting block 23, wherein when the second connecting plate 2 and the instrument tube beam 4 are in contact, the second limiting block is limited within the second limiting hole.

[0097] Please see Figure 2 and Figure 3In some possible embodiments, the instrument tube beam 4 is provided with a relief groove 41, and a connecting ear 42 is provided on one side wall of the relief groove 41. The connecting ear 42 is arranged parallel to the second connecting plate 2. The first connecting plate 1 is placed in the relief groove 41, and the second connecting plate 2 is attached and fixed to the connecting ear 42.

[0098] By setting the clearance groove 41, the first connecting plate 1 can be conveniently enclosed in the clearance groove 41, which helps to ensure the connection stability between the instrument tube beam 4 and the conductive sheet structure; by setting the connecting ear 42, and the connecting ear 42 being arranged parallel to the second connecting plate 2, the second connecting plate 2 can be conveniently connected, and the aforementioned first limiting hole 421 can be conveniently set.

[0099] The design of the relief groove 41 and connecting ear 42 on the instrument tube beam 4 allows the first connecting plate 1 to be placed in the relief groove 41, and the second connecting plate 2 to be attached and fixed on the connecting ear 42. Therefore, the structural arrangement of the relief groove 41 and connecting ear 42 not only provides suitable space and support for the installation of the conductive sheet, but also helps to optimize the installation layout of the entire vehicle instrument panel grounding device on the instrument tube beam 4, improving installation efficiency and conductivity.

[0100] Optionally, the clearance groove 41 is not provided on the instrument tube beam 4. In this case, the second ear plate is directly provided on the edge side of the instrument tube beam 4, and the second ear plate is parallel to the second connecting plate 2 so that the second ear plate and the second connecting plate 2 are fitted and fixed together.

[0101] At this time, the second grounding bolt 6 is inserted between the second ear plate and the second connecting plate 2.

[0102] Based on the same inventive concept, this application also provides a vehicle that includes the aforementioned vehicle dashboard grounding device.

[0103] The vehicle provided in this application, having included the aforementioned vehicle dashboard grounding device, possesses all the beneficial effects of the aforementioned vehicle dashboard grounding device. It is highly stable and durable, improves the conductivity between the instrument panel beam 4 and the vehicle body 3, reduces manufacturing costs, improves the economic applicability of the conductive connection between the instrument panel beam 4 and the vehicle body 3, and is conducive to optimizing the electrical system performance of the instrument panel, thereby improving the overall performance and reliability of the vehicle.

[0104] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
