Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle. Background Technology
[0002] Automobile body panels are equipped with wiring harness connectors, which are primarily used to ensure efficient and reliable transmission of power and signals between various electrical components in the vehicle. Automobiles typically include clips with holes directly drilled into the body panel. One end of the clip connects to the connector, and the other end connects to the hole, allowing the connector to be secured to the body panel. However, because many areas of the body panel extend to the outside of the vehicle, such as the floor, wheel arches, and front bulkhead, directly drilling holes in the panel can lead to problems such as water leakage, noise, and poor sealing and insulation. This, in turn, limits the space available for connector placement and makes installation difficult. Utility Model Content
[0003] This application provides a vehicle for solving the problem of limited space for connector placement, which leads to difficulties in placement.
[0004] This application provides a vehicle, which includes a connector, a body panel, and a mounting component. The body panel includes fasteners for fixed connection, and the fasteners are provided with threads.
[0005] The connector is connected to the mounting component, which includes a first opening and a connecting cavity. A limiting part is provided in the connecting cavity. The fastener can extend into the connecting cavity through the first opening, and the thread of the fastener can engage with the limiting part, so that the connector is fixed to the body sheet metal by the mounting component.
[0006] In this solution, fasteners can be welded to the body sheet metal. Compared to the traditional method of directly drilling holes in the body sheet metal, this application uses the threads of the fasteners to engage with the limiting part of the mounting component, so that the connector connected to the mounting component can be fixed to the body sheet metal by the fasteners. This avoids problems such as water leakage, noise, and poor sealing caused by drilling holes. Furthermore, the fasteners can be placed in various areas of the body sheet metal, meaning that the fastener placement position is not restricted, which in turn makes the connector placement space unrestricted, facilitating personnel placement and improving production efficiency.
[0007] In this solution, at least two limiting portions are provided at intervals along the radial direction of the mounting component. The limiting portions are capable of elastic deformation along the radial direction of the mounting component, and at least two of the limiting portions abut against the threads of the fastener in a first direction.
[0008] In this solution, the limiting part includes a guide surface, which is inclined. The inclination angle of the guide surface relative to the first direction is α, and the inclination angle of the thread relative to the first direction is β°, satisfying 0°≤|α-β|≤2°.
[0009] In this scheme, the tilt angle α of the guide surface satisfies 28°≤α≤32°.
[0010] In this scheme, at least two of the limiting parts have a height difference along the first direction.
[0011] In this solution, there is a gap d1 between at least two of the limiting parts along the radial direction of the mounting component, and the major diameter of the thread of the fastener is d2, satisfying d1 < d2.
[0012] In this design, the end of the mounting component facing away from the first opening is provided with a hook, and the connector includes a protrusion, the hook being able to engage with the protrusion.
[0013] In this design, the sidewall of the mounting component is provided with a second opening at intervals, the second opening is connected to the connecting cavity, and the mounting component is also provided with a reinforcing part at the second opening.
[0014] In this solution, the fastener is a bolt.
[0015] In this design, the material of the mounting component is polyhexamethylene adipamide.
[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0036] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0037] In one specific embodiment, the present application will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0038] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.
[0039] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0040] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.
[0041] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.
[0042] This application provides a vehicle, such as Figure 1 As shown, the vehicle includes a connector 2, a body sheet metal, and a mounting component 1. The body sheet metal includes a fastener 3 for fixed connection. The fastener 3 is provided with a thread 31. The connector 2 is connected to the mounting component 1. The mounting component 1 includes a first opening 11 and a connecting cavity 12. A limiting part 13 is provided in the connecting cavity 12. The fastener 3 can extend into the connecting cavity 12 through the first opening 11. The thread 31 of the fastener 3 can engage with the limiting part 13 so that the connector 2 is fixed to the body sheet metal by the mounting component 1.
[0043] Specifically, the mounting component 1 has a frustum-shaped structure, and the fastener 3 can be welded to the body sheet metal. Compared to the traditional method of directly drilling holes in the body sheet metal, this application uses the thread 31 of the fastener 3 to engage with the limiting part 13 of the mounting component 1, so that the connector 2 connected to the mounting component 1 can be fixed to the body sheet metal by the fastener 3. This avoids problems such as water leakage, noise, and poor sealing caused by drilling holes. Furthermore, the fastener 3 can be arranged in various areas of the body sheet metal, meaning that the arrangement position of the fastener 3 is not restricted, thereby making the arrangement space of the connector 2 unrestricted, facilitating personnel placement, and improving production efficiency.
[0044] It should be noted that, for example, Figure 1 In the embodiment shown, the first direction X can be the height direction of the mounting component 1.
[0045] In one possible implementation, such as Figure 1 As shown, at least two limiting portions 13 are provided at intervals along the radial direction of the mounting member 1 in the connecting cavity 12. The limiting portions 13 can be elastically deformed along the radial direction of the mounting member 1 so that at least two limiting portions 13 abut against the thread 31 of the fastener 3 in the first direction X.
[0046] In this embodiment, along the first direction X, the mounting member 1 is connected between the fastener 3 and the connector 2. At least two limiting portions 13 abut against the threads 31 of the fastener 3 along the first direction X. Simultaneously, the limiting portions 13 can engage between two adjacent thread teeth along the first direction X, reducing the risk of the fastener 3 disengaging from the connecting cavity 12 of the mounting member 1 along the first direction X. This improves the reliability and stability of the connection between the connector 2 and the fastener 3, thereby enhancing the reliability and stability of the connector 2's connection to the vehicle body sheet metal and contributing to improved vehicle structural stability. Furthermore, at least two limiting portions 13 can abut against the same thread 31 segment projected radially from the fastener 3 along the first direction X. That is, along the first direction X, the two limiting portions 13 can engage with the two nearest thread teeth, ensuring smooth engagement of both limiting portions 13 with the threads 31 when the mounting member 1 is connected to the fastener 3. This also helps reduce the risk of the limiting portions 13 disengaging from the threads 31 due to vehicle movement, further improving the reliability and stability of the connection between the fastener 3 and the mounting member 1.
[0047] When it is necessary to connect the connector 2 to the body sheet metal, the first opening 11 is aligned with the fastener 3 so that the fastener 3 can be inserted into the connection cavity 12. The mounting part 1 is pressed towards the fastener 3 in the first direction X. Under the pressure of the outer end face of the thread 31, the limiting part 13 is elastically deformed radially along the mounting part 1. Then, the mounting part 1 is slightly lifted away from the fastener 3 in the first direction X. Under the action of the rebound force, the limiting part 13 rebounds radially so that the limiting part 13 is engaged with the thread 31. Compared with the mounting part and the fastener being locked by screwing in the thread, i.e., the threaded connection, the direct engagement of the limiting part 13 with the thread 31 can reduce the connection time, facilitate operation, and further improve production efficiency.
[0048] In one possible implementation, such as Figures 1-3 As shown, the material of the mounting part 1 is polyhexamethylene adipamide (PA66) so that the mounting part 1 has good plasticity, wear resistance and high mechanical strength, and the PA66 material has a certain elasticity so that the limiting part 13 of the mounting part 1 has good elastic deformation ability so that the limiting part 13 can be engaged with the thread 31.
[0049] In one possible implementation, such as Figure 1 and Figure 4 As shown, fastener 3 is a bolt. The bolt has a simple structure, is easy to produce and use, and helps to reduce the production cost of the vehicle.
[0050] In one possible implementation, such as Figure 3 and Figure 4As shown, the limiting part 13 includes a guide surface 131, which is inclined. The inclination angle of the guide surface 131 relative to the first direction X is α, and the inclination angle of the thread 31 relative to the first direction X is β°, satisfying 0°≤|α-β|≤2°. In some embodiments, |α-β| can be 0°, 0.5°, 1°, 1.5°, 2°, etc.
[0051] Specifically, the guide surface 131 of the limiting part 13 is inclined in approximately the same direction as the thread 31, so as to guide the fastener 3 to smoothly extend into the connecting cavity 12 of the mounting part 1, thereby improving the smoothness and convenience of the connection between the fastener 3 and the mounting part 1. When 0°≤|α-β|≤2° is satisfied, that is, the difference in the angle of inclination of the guide surface 131 and the thread 31 relative to the first direction X is small, it is beneficial to improve the smoothness of the fastener 3 extending into the connecting cavity 12, reduce the installation difficulty, and at the same time, it is beneficial to reduce the risk of the limiting part 13 coming off between two adjacent thread teeth along the first direction X, thereby improving the reliability and stability of the engagement between the limiting part 13 and the thread 31.
[0052] In one possible implementation, such as Figure 3 As shown, the tilt angle α of the guide surface 131 satisfies 28°≤α≤32°. In some embodiments, the tilt angle α of the guide surface 131 can be 28°, 28.5°, 29°, 29.5°, 30°, 30.5°, 31°, 31.5°, 32°, etc.
[0053] In this embodiment, the tilt angle α of the guide surface 131 satisfies 28°≤α≤32°, so that the tilt angle of the guide surface 131 is moderate, so that the guide surface 131 and the outer end face of the thread 31 can fit well. At the same time, it helps to reduce the risk that the thread 31 of the fastener 3 cannot pass the limiting part 13, that is, it helps to reduce the risk that the fastener 3 cannot be inserted into the connecting cavity 12, and improves the feasibility and reliability of the connection between the fastener 3 and the mounting part 1.
[0054] In one possible implementation, such as Figure 1 As shown, since the thread 31 is spirally rising, at least two limiting parts 13 are provided with a height difference along the first direction X, so that at least two limiting parts 13 can abut against the thread 31, thereby enabling at least two limiting parts 13 to jointly restrict the fastener 3 from disengaging from the connecting cavity 12, greatly improving the firmness of the connection between the fastener 3 and the mounting part 1.
[0055] In one possible implementation, such as Figure 3 and Figure 4As shown, at least two limiting portions 13 have a gap d1 along the radial direction of the mounting part 1, and the major diameter of the thread 31 of the fastener 3 is d2, satisfying d1 < d2. During the process of the fastener 3 and the mounting part 1 moving closer together along the first direction X, the thread 31 compresses the limiting portion 13 along the radial direction of the mounting part 1, causing the limiting portion 13 to elastically deform away from the axis along the radial direction of the mounting part 1. Then, the mounting part 1 is slightly lifted upwards, and the limiting portion 13 rebounds towards the axis along the radial direction of the mounting part 1 under the action of the rebound force, so that the limiting portion 13 engages between two adjacent thread teeth along the first direction X. Therefore, d1 < d2 is satisfied so that the thread 31 can drive the limiting portion 13 to elastically deform and automatically engage with the thread 31. Simultaneously, d1 < d2 is satisfied so that after the limiting portion 13 engages with the thread 31, it can prevent the limiting portion 13 from disengaging from the thread 31 along the first direction X.
[0056] In one specific embodiment, the fastener 3 can be an M5 stud, that is, the major diameter of the thread 31 is 5mm, and the gap d1 between at least two limiting parts 13 satisfies 3.7mm≤d1≤4mm, wherein the gap d1 can be 3.7mm, 3.8mm, 3.9mm, 4mm, etc., and the pitch P satisfies 0.8mm≤P≤1.6mm, wherein the pitch P can be 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, etc.
[0057] In one possible implementation, such as Figure 2 and Figure 5 As shown, the end of the mounting component 1 facing away from the first opening 11 is provided with a hook 16, and the connector 2 includes a protrusion 21, the hook 16 being able to engage with the protrusion 21.
[0058] In this embodiment, the hook 16 can be elastically deformed and can hook the protrusion 21, so that the protrusion 21 can be engaged with the hook 16. This connection structure is simple and has connection stability.
[0059] In one possible implementation, such as Figure 1 and Figure 2 As shown, the side wall of the mounting component 1 is provided with a second opening 14 at intervals. The second opening 14 communicates with the connecting cavity 12. The mounting component 1 is also provided with a reinforcing part 15 at the second opening 14.
[0060] In this embodiment, the second opening 14 is used for personnel to observe the engagement between the limiting part 13 and the thread 31. At the same time, the reinforcing part 15 is located at the second opening 14, which helps to improve the structural strength of the mounting part 1, and thus helps to improve the structural strength of the connection between the connector 2 and the body sheet metal.

Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
