Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and particularly relates to a multi - head connector for an automobile wheel hub. Background Art

[0002] In the field of automobile manufacturing technology, the currently widely used automobile wheel hub connectors mainly rely on single - head connection methods. However, this traditional design exposes significant defects. During vehicle driving, various complex dynamic loads will be encountered. Since the stress of the single - head connector is highly concentrated at a single connection point, it is extremely easy to cause loosening, wear, and even breakage in extreme cases, thus resulting in insufficient connection stability and posing a serious hidden danger to driving safety.

[0003] In addition, to ensure the connection strength, single - head connectors are usually designed to be relatively large in size. This not only increases the overall weight of the wheel hub system, has an adverse impact on the vehicle's power performance and fuel economy, but also occupies a large amount of space, greatly restricting the reasonable layout of components inside and around the wheel hub. In the current context of pursuing compact and lightweight overall vehicle design, these drawbacks of single - head connectors are becoming increasingly prominent and have become technical problems that need to be solved urgently.

[0004] Therefore, this application has developed a multi - head connector for an automobile wheel hub to solve the problems existing in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a multi - head connector for an automobile wheel hub to solve the problems of insufficient stability and large space occupation of single - head connectors in the prior art.

[0010] The cable core, one end of the cable core is connected to the docking part, and the other end extends along the first direction for transmitting electrical signals or data.

[0011] Preferably, the outer wall surface of the mounting plate is arc-shaped and concentric with the wheel hub, so that the surface of the housing at the outermost end along the radial direction of the wheel hub is tangent to the outer wall surface of the mounting plate.

[0027] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0028] As Figures 1-4 shown, a multi - head connector for an automobile wheel hub includes a housing assembly 1, a sleeve assembly 3, a docking part 4, and a cable core 5. The housing assembly 1 is composed of three interconnected housings 11. Each housing 11 has a hollow structure inside and is provided with a mounting surface 12. These three mounting surfaces 12 are closely attached to form a stable overall structure. On the opposite side of the mounting surface 12, a mounting plate 2 protrudes on the mounting surface 12. Through the mounting plate 2, the entire housing assembly 1 can be firmly installed on the wheel hub, ensuring the stability and reliability of the connector.

[0029] Among them, the sleeve assembly 3 is arranged inside the housing assembly 1, and its shape perfectly matches that of the housing assembly 1, providing an effective accommodation and protection space for internal components, not only enhancing the overall structural strength of the connector but also ensuring the safe operation of internal cables and components in harsh environments. The docking part 4 adopts an L - shaped bending structure, enabling the docking part 4 to flexibly adapt to different spatial layouts during connection. One end of the docking part 4 can penetrate the sleeve assembly 3 and the mounting surface 12 and extend along the second direction to the outside of the housing assembly 1, thus facilitating connection with external devices and realizing smooth transmission of electrical signals or data. The other end is closely connected to the cable core 5, ensuring the stability and reliability of signal transmission. The cable core 5 extends along the first direction and is routed and connected according to actual needs to meet the signal transmission requirements in different application scenarios, enabling the multi - head connector to be widely used in various connection scenarios of automobile wheel hubs.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 5As shown, the arrangement of the housing assembly 1 has significant characteristics. It is arranged along the first direction and is inclined relative to the diameter direction of the hub. The first direction does not completely coincide with the radial direction of the hub, but is set at a certain angle to the diameter direction of the hub. At the same time, the second direction is perpendicular to the first direction, enabling the connector to have better resistance in different directions and maintaining the stability of the connector.

[0031] For traditional single - headed connectors, their installation method is usually along the radial direction of the hub. This causes one end of the connector to protrude outside the hub along the radial direction of the hub. To stably install the connector on the hub, an additional fixed end needs to be set, which not only increases the space requirement during the installation of the connector, but also, to ensure the stability of the installation, its size is often designed relatively large.

[0032] In contrast, the multi - headed connector in this application avoids this problem through the inclined setting of the housing 11. Due to the inclination of the housing 11, the part that protrudes outside the hub along the radial direction of the hub at one end is reduced, thus significantly reducing the space occupied by the connector. In addition, multiple mounting holes 21 are designed on the mounting plate 2. The multi - hole mounting method can not only effectively prevent the connector from shaking, improve the stability of the installation, but also reduce the size of each mounting hole 21, thereby correspondingly reducing the space occupied by the mounting plate 2, achieving a compact and stable installation of the multi - headed connector.

[0033] For further illustration, in terms of stability, the multiple mounting holes 21 achieve multi - point fixation, greatly enhancing the connection strength between the connector and the installation base, significantly improving the stability and reliability of the connection. This enables the connector to always maintain stable performance whether facing external factors such as vibration, impact, or temperature changes, effectively avoiding problems such as signal interruption and poor contact caused by loose or unstable connections; in terms of the volume of the housing 11, the multi - point fixation design enables the overall volume of the housing 11 to be reduced. In the traditional single - point fixation method, a larger housing space may be required to ensure the connection strength and stability, while the multi - point fixation method of the multiple mounting holes 21 reasonably reduces the volume of the housing 11 on the premise of ensuring the connection effect. It is worth emphasizing that although the volume of the housing 11 has decreased, this has not had any negative impact on the overall function. On the contrary, it can also make the housing assembly 1 occupy less space while completely retaining all functions.

[0034] Furthermore, the outer wall surface of the mounting plate 2 is designed to be arc-shaped, and this arc is concentric with the wheel hub. This ensures that when the housing 11 extends radially along the wheel hub, the outermost end surface thereof can just be tangent to the outer wall surface of the mounting plate 2, thereby achieving a smooth transition and close fit between the housing 11 and the mounting plate 2, without occupying extra space for accommodating the housing 11. The part of the housing 11 that extends beyond the wheel hub and the mounting plate 2 only occupy the same space, reducing the space occupation ratio. On the mounting plate 2, mounting holes 21 that are exactly equal in number to the housing 11 are provided. These mounting holes 21 are precisely arranged on one side corresponding to the housing 11 to ensure that each housing 11 can be fixed through its exclusive mounting hole 21, eliminating the need to set a fixed end to fix the connector, greatly reducing the space occupation. It should be noted that the arc formed by connecting the center points of these mounting holes 21 is also concentric with the wheel hub. The concentric design uniquely determines the relative position relationship between the connector and the wheel hub. During installation, there is no need for repeated adjustment, enabling quick and accurate positioning. It can evenly disperse stress and avoid local stress concentration. When the vehicle is running, the wheel hub bears complex loads. The concentric arrangement enables the connector and the wheel hub to be stressed synchronously, preventing single-point overload caused by eccentricity and reducing the risk of the connector loosening or falling off.

[0035] Furthermore, as Figures 3-4 shown, two adjacent housings 11 are closely combined together, but at their connection, a clearance hole 13 is formed. The clearance hole 13 not only helps to achieve the light weight of the structure but also plays a buffering role, absorbing and dispersing external impact forces. On the outer wall surface of the docking part 4, a groove 41 is provided for accommodating a gasket 42. The gasket 42 plays a role of sealing and buffering here. To ensure that the gasket 42 can be stably and effectively installed, the accommodating space provided by the groove 41 is significantly larger than the volume of the gasket 42. This not only enables the gasket 42 to be easily and accurately installed in place but also reserves enough space so that when subjected to external forces, the gasket 42 can have a certain amount of deformation or movement space, thereby effectively absorbing and dispersing stress, preventing structural damage or performance degradation caused by stress concentration, and enabling the force to have a space for release during the transmission process, significantly improving the structural stability and durability of the connector.

The purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly, and it should not be used to limit the protection scope of the present utility model.
