Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted equipment power supply, specifically to a fastening power interface for vehicle-mounted applications. Background Technology

[0002] In the current automotive industry, with the diversification and intelligent development of in-vehicle devices, users' demand for convenient power supply is increasing. However, traditional power supply methods, such as external power cords, suffer from problems such as messy wiring, poor aesthetics, and inconvenience. For example, devices such as phone holders, action cameras, and air purifiers usually require external power cords, which not only affects the cleanliness of the car interior but also makes them cumbersome to carry, ultimately making it inconvenient to draw power from in-vehicle devices. Utility Model Content

[0003] The present invention aims to provide a secure power interface for vehicle use, so as to solve the problem of cumbersome power supply for vehicle equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a vehicle-mounted fastening power interface, comprising a housing, the housing being provided with a fixing component for connecting to a vehicle power source, the housing being detachably connected to a connecting component for connecting vehicle equipment via the fixing component, the connecting component comprising a connecting shell, the connecting component further comprising a connector and an elastic member for connecting the fixing component and the vehicle equipment power source, the connector being slidably connected to the connecting shell, the elastic member being elastically connected to both ends of the connecting shell and passing through the connecting shell, the housing having a first connecting hole for the connector to pass through, the connector being used to pass through the first connecting hole and connect to the fixing component.

[0005] The beneficial effects of this solution are as follows: First, the fixing component is connected to the vehicle power supply light, and the housing and vehicle body are fixedly connected. Then, the connecting component is fixedly connected to the housing through the fixing component. At this time, the connecting component is connected to the positive and negative terminals of the vehicle power supply through the fixing component. Next, the vehicle device is connected to the end of the connecting component away from the fixing component. The vehicle device is connected to the vehicle power supply through the connecting component. Since the connecting component has a sliding connecting component and an elastic connecting component, the connecting component and the elastic component are connected to the negative and positive terminals of the vehicle power supply respectively through the fixing component. When the vehicle device is connected to the connecting component, the connection is made through the top of the connecting component and the top of the elastic component, thus achieving an electrical connection between the vehicle device and the vehicle power supply. Compared with existing technologies, there is no need for a data cable, making it convenient for users to carry and install. It is also quick and easy to install, thus achieving the goal of convenient installation of vehicle devices.

[0006] By sliding the connector onto the connecting shell and elastically connecting the elastic element onto the connecting shell, when the height or angle of the vehicle-mounted equipment needs to be adjusted, relative rotation or sliding will occur between the connector and the vehicle-mounted equipment, and between the connector and the fixed component. Due to the limited installation position reserved by the elastic element, for small height changes at the bottom of the vehicle-mounted equipment, when the vehicle-mounted equipment rises a small distance, the elastic element will naturally extend, ensuring that the upper and lower ends of the elastic element are always in contact with the vehicle-mounted equipment and the fixed component, respectively. When the vehicle-mounted equipment descends a small distance, the elastic element will be slightly bent under pressure, similarly ensuring that the upper and lower ends of the elastic element are in contact with the vehicle-mounted equipment and the fixed component, respectively. Therefore, it is possible to ensure that the vehicle power supply is always electrically connected to the vehicle-mounted equipment when the angle and height of the vehicle-mounted equipment are adjusted, thus enabling fine-tuning of the vehicle-mounted equipment.

[0007] On the other hand, when the reserved length of the connector at the bottom of the vehicle-mounted device is different, the reserved length of the connector at the housing needs to be adjusted according to the actual situation of the vehicle-mounted device before connecting the connector to the housing. This avoids the need to adjust the device after installation, thus enabling the installation of various different vehicle-mounted devices. Compared with the existing technology, it can not only install various different vehicle-mounted devices, but also make fine adjustments to the installed vehicle-mounted devices.

[0008] Preferably, as an improvement, the fixing component includes a conductive plate detachably connected to the housing and a conductive ring installed on the housing. A connecting groove for the connecting component to be embedded is provided on the side of the housing away from the fixing component. A first connecting hole is provided on the side of the connecting groove near the fixing component, and the conductive ring is embedded at the bottom end of the connecting groove.

[0009] The beneficial effects of this solution are as follows: When installing the connecting component and the housing, the bottom end of the connecting component is embedded in the connecting groove, and the connector penetrates the housing through the first connecting hole and is fixedly connected to the conductive plate of the fixing component. At the same time, since the conductive ring is embedded at the bottom end of the connecting groove, and since the elastic element protrudes and is connected to the upper and lower ends of the connecting housing, the elastic element abuts against the conductive ring at the bottom end of the connecting groove through the connecting housing. This achieves both the connection of the connecting component to the vehicle power supply through the fixing component and the fixation of the connector to the housing through the fixing component.

[0010] Preferably, as an improvement, the conductive plate and the housing are provided with corresponding threaded holes on both sides, the conductive plate is provided with a second connecting hole for the connector to pass through, and a fastener for fixing the connector is fixedly provided on the conductive plate at the second connecting hole.

[0011] The beneficial effects of this solution are as follows: by setting threaded holes, the conductive plate can be installed at the bottom of the housing with screws, thereby realizing the detachable connection of the conductive plate. In addition, the connector is connected to the fixing part through the second connecting hole to realize the power connection.

[0012] Preferably, as an improvement, the connector is configured as a rod, and a screw is provided at the bottom end of the connector, and the fastener is configured as a nut.

[0013] The beneficial effects of this solution are as follows: the bottom end of the connector is threaded with the nut. When it is necessary to adjust the angle of the vehicle-mounted equipment, the connector will rotate through the screw, which will inevitably drive the vehicle-mounted equipment to move in the height direction. When it is necessary to adjust the height, it can also be fine-tuned by rotating the angle.

[0014] Preferably, as an improvement, the connecting shell includes a connecting post and a rotating wheel fixed to the outer ring of the top of the connecting post. A sliding cavity is provided inside the connecting post, and a slider is fixed to the outer ring of the connecting member. The horizontal cross-sections of the slider and the movable cavity are polygons of equal size and shape, and the outer wall of the slider is tangent to the inner wall of the sliding cavity.

[0015] The beneficial effects of this solution are as follows: By setting a slider, on the one hand, the slider can be guided to slide within the inner cavity of the connecting column; on the other hand, since the cross-sections of the slider and the inner cavity of the connecting column are both polymorphic and have the same structure and size, the inner cavity of the connecting column has a rotational limiting effect on the slider. By rotating the connecting shell with the rotating wheel, the inner cavity of the connecting column drives the connecting part to rotate together. After rotation, the angle adjustment is completed. At this time, the height of the connecting part changes, and the connecting part generates a relative displacement within the inner cavity of the connecting column through the guidance of the slider. The vehicle-mounted equipment with the changed height achieves power connection through the automatic adjustment of the elastic element.

[0016] Preferably, as an improvement, the outer ring of the connecting column is provided with an adjustment cavity for installing the elastic element, and the rotating wheel is provided with an installation cavity for installing the elastic element. The adjustment cavity and the installation cavity are connected, and the elastic element is connected between the upper and lower ends of the connecting column through the installation cavity and the adjustment cavity.

[0017] The beneficial effects of this solution are as follows: Since the elastic element has a certain degree of elasticity, and the thickness of the adjustment cavity and the mounting cavity is greater than the thickness of the elastic element, the elastic element has a certain deformation space in the adjustment cavity and the mounting cavity, which can accommodate the elastic element when it is compressed and bent.

[0018] Preferably, as an improvement, the conductive ring and the conductive plate are used to connect the positive and negative terminals of the vehicle power supply, respectively, and the two ends of the elastic element are used to abut against the conductive ring and the positive terminal of the vehicle equipment, respectively.

[0019] The beneficial effects of this solution are as follows: the elastic element is connected to the positive terminal, and the connector is connected to the negative terminal via a screw and nut. During installation, the connector is first placed in the connector groove, and then the rotating wheel is rotated to connect the connector rod to the fixed component. The power connection is initiated by connecting the positive terminal before the negative terminal. When the connector needs to be removed from the housing, the rotating wheel is rotated, causing the connector to rotate and disconnecting the screw and nut at the bottom of the connector. After disconnection, the connector is still placed in the connector groove. Finally, it is removed. In this case, the power disconnection is initiated by disconnecting the negative terminal before the positive terminal. This is because in automotive circuit design, the negative terminal is usually connected to the vehicle body to form a grounding system. Therefore, prioritizing the disconnection of the negative terminal can avoid the risk of a short circuit between the positive and negative terminals and reduce the possibility of electric shock.

[0020] Preferably, as an improvement, the connecting groove is provided with an annular groove at the connecting hole for the insertion of a conductive ring, and the diameter of the annular groove is larger than the diameter of the connecting hole.

[0021] The beneficial effects of this solution are as follows: by setting the annular groove, it is possible to prevent the connector from contacting the conductive ring located in the annular groove during the process of passing through the first connecting hole, thereby avoiding the risk of short circuit and ensuring the safety of the operator.

[0022] Preferably, as an improvement, the nut, connector, and elastic element are all made of conductive material.

[0023] Preferably, as an improvement, the diameter of the outer ring of the connecting post is smaller than the diameter of the inner ring of the connecting groove.

[0024] The beneficial effects of this solution are as follows: when the connecting shell is embedded in the connecting groove, the connecting post at the bottom is embedded in the connecting groove. Since the elastic element is set on the outer ring of the connecting post, when there is a gap between the outer ring of the connecting post and the inner ring of the connecting groove, it can ensure that the elastic element also has space for bending deformation between the two.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: housing 1, first connecting hole 11, connecting groove 12, annular groove 121, first convex ring 122, fixing assembly 2, conductive plate 21, second connecting hole 211, nut 212, conductive ring 22, connecting assembly 3, connecting shell 31, rotating wheel 311, mounting cavity 3111, second mounting gap 3112, connecting post 312, adjusting cavity 3121, second convex ring 3122, adjusting plate 3123, first mounting gap 3124, connecting piece 32, slider 321, and elastic element 33.

[0032] Example

[0033] A type of secure power connector for automotive applications, such as... Figure 1 , Figure 3 As shown, the device includes a housing 1 for fixed connection with the vehicle body. The housing 1 is made of a non-conductive material. A connecting groove 12 is formed at the top of the housing 1, and the connecting groove 12 is shaped like a frustum, wider at the top and narrower at the bottom. A first connecting hole 11 is formed at the bottom of the connecting groove 12 on the housing 1, penetrating the bottom of the housing 1. The diameter of the first connecting hole 11 is smaller than the diameter of the bottom surface of the connecting groove 12. An annular groove 121 is formed at the bottom of the connecting groove 12 around the first connecting hole 11. The diameter of the annular groove 121 is smaller than the diameter of the bottom surface of the connecting groove 12 but larger than the diameter of the first connecting hole 11. The upper and lower bottom surfaces of the groove 12 and the first connecting hole 11 are all coaxially arranged. At the bottom end of the groove 12, a first protruding ring 122 is formed between the annular groove 121 and the first connecting hole 11. The first protruding ring 122 is set upward. A conductive ring 22 is embedded in the annular groove 121. Therefore, the conductive ring 22 is located between the outer ring of the protruding ring and the inner ring of the bottom end of the groove 12. A positive electrode plate and a baffle plate are integrally arranged on both sides of the conductive ring 22. The bottom end of the housing 1 is located on both sides of the bottom end of the groove 12 and a positive electrode slot is symmetrically opened for the positive electrode plate to pass through. The conductive ring 22 contacts the positive power of the vehicle power supply through the positive electrode plate.

[0034] like Figure 1 , Figure 4As shown, a conductive plate 21 is detachably connected to the bottom of the housing 1. The conductive plate 21 has a second connecting hole 211 corresponding to the first connecting hole 11. The conductive plate 21 also has an integrally formed negative electrode plate, which is used to connect to the negative terminal of the vehicle power supply. A nut 212 is fixedly welded to the bottom of the conductive plate 21 at the second connecting hole 211. Both ends of the nut 212 are open to facilitate threaded connection. Threaded holes are opened on both sides of the conductive plate 21. The bottom of the housing 1 also has a threaded hole corresponding to the threaded hole on the conductive plate 21. During installation, the conductive plate 21 is threaded to the bottom of the housing 1 by screws, thereby realizing the detachable connection of the conductive plate 21.

[0035] like Figure 2 , Figure 4 As shown, it also includes a connecting assembly 3, which includes a connecting shell 31. The connecting shell 31 includes a top rotating wheel 311 and a connecting post 312 fixed to the bottom of the rotating wheel 311. The connecting post 312 is integrally formed with the rotating wheel 311. The outer ring of the rotating wheel 311 has several anti-slip patterns vertically arranged. When the rotating wheel 311 is manually driven to rotate, the rotating wheel 311 drives the connecting post 312 to rotate. The outer ring of the connecting post 312 has symmetrically arranged adjustment cavities 3121 on both sides. Vertically positioned, the rotating wheel 311 also has symmetrically arranged mounting cavities 3111 on both sides. The mounting cavities 3111 and adjusting cavities 3121 correspond one-to-one and are interconnected. A second convex ring 3122 is coaxially arranged at the bottom end of the connecting post 312, with its opening facing downwards. The second convex ring 3122 corresponds to the second connecting hole 211 and has the same diameter. An adjusting plate 3123 is vertically arranged on the adjusting cavity 3121, with the adjusting plate 3123 having a bottom end... The height is higher than that of the second convex ring 3122. There is a first installation gap 3124 between the adjusting plate 3123 and the second convex ring 3122. The first installation gap 3124 is set perpendicular to the adjusting plate 3123. The installation cavity 3111 is vertically opened, and a second installation gap 3112 is horizontally opened at the top of the installation cavity 3111. The first installation gap 3124, the adjusting cavity 3121, the installation cavity 3111, and the second installation gap 3112 together form the installation position for installing the elastic element 33. The elastic element 33 is a conductive spring made of conductive material. The conductive spring includes a vertical part and a snap-fit ​​part that is perpendicular to the vertical part. During installation, the upper and lower ends of the conductive spring are snapped into the second installation gap 3112 and the first installation gap 3124, respectively. The vertical part is placed in the vertical space formed by the adjusting cavity 3121 and the installation cavity 3111. There is also a gap between the outer ring of the connecting post 312 and the inner wall of the connecting groove 12.

[0036] like Figures 4-5As shown, after installation, the second protruding ring 3122 of the connecting post 312 abuts against the first protruding ring 122 at the bottom of the connecting groove 12. Simultaneously, since the adjusting plate 3123 is located on the outer ring of the second protruding ring 3122, and the elastic element 33 is installed in the mounting position composed of 'first mounting position - adjusting cavity 3121 - mounting cavity 3111 - second mounting position', the bottom end of the elastic element 33 wraps around the bottom end of the adjusting plate 3123. Therefore, the adjusting plate 3123 pushes the elastic element 33 against the conductive ring 22, making the conductive ring 22 electrically connected to the elastic element 33. A small gap exists between the bottom end of the elastic element 33 and the bottom end face of the adjusting plate 3123, and the top end is in the second mounting gap 3112. The elastic element 33 is horizontally positioned, and there is also a gap between the second mounting position and the horizontal end of the elastic element 33. Also, for the elastic element 33... When installed in the connecting assembly 3 and placed in the connecting groove 12, there are gaps between the elastic element 33 and the adjusting plate 3123, between the outer ring of the connecting post 312 and the inner ring of the connecting groove 12, and between the horizontal end of the elastic element 33 and the second mounting gap 3112. In addition, the vertical part of the elastic element 33 is located in the adjusting cavity 3121 and the mounting cavity 3111. Therefore, when the vehicle-mounted equipment rotates and adjusts downward, the vehicle-mounted equipment drives the rotating wheel 311 to move downward. At this time, the elastic element 33 is bent under pressure and can also be compressed so that there is no gap between the horizontal end face of the elastic element 33 and the second mounting gap 3112, or the elastic element 33 is tightly attached to the bottom end of the adjusting plate 3123. This ensures that the positive terminal of the vehicle power supply is not disconnected when the rotating wheel 311 moves downward, thereby achieving the purpose of fine adjustment of the vehicle-mounted equipment.

[0037] like Figures 4-5 As shown, a connector 32 is vertically slidably disposed within the connecting post 312. The connector 32 is also made of conductive material. In this embodiment, the connector 32 is rod-shaped, and its bottom end is a screw. The inner ring cross-section of the connecting post 312 is polygonal. A slider 321 is coaxially fixedly disposed on the outer ring of the connector 32. The cross-sectional shape of the slider 321 is a polygon congruent to the inner ring cross-section of the connecting post 312. The slider 321 is embedded in the inner cavity of the connecting post 312, and several sides of the slider 321 are tangent to the inner ring of the connecting post 312. The slider 321 is used to vertically guide the connector 32. When connecting, the connecting post 312 is placed in the connecting groove 12, and the rotating wheel 311 is rotated. The rotating wheel 311 drives the connector 32 to rotate. The connector 32 passes through the first connecting hole 11 and the second connecting hole 211 and is threadedly connected to the nut 212. The top of the rod-shaped connector 32 can be provided with various types of connector heads to connect to the negative terminal of the vehicle power supply. In this embodiment, the connector 32 is set as a double-ended screw. Therefore, the vehicle equipment is also connected to the top of the connector 32 through the reserved threaded hole to realize the connection of the negative terminal.

[0038] Its working principle is as follows: When the angle of the vehicle-mounted equipment needs to be adjusted, the rotating wheel 311 is rotated. The rotating wheel 311 drives the rod-shaped connecting member 32 to rotate relative to the nut 212. Therefore, after the angle adjustment is completed, the vehicle-mounted equipment moves in the numerical direction under the action of the connecting member 32. When the vehicle-mounted equipment moves down, the elastic member 33 is squeezed and bent. When the vehicle-mounted equipment moves up, the elastic member 33 returns to its original shape. The elastic member 33 can only meet a certain height adjustment of the vehicle-mounted equipment, commonly known as fine adjustment. However, for adjustments with excessive height, the rotating wheel 311 needs to be rotated continuously. The rotating wheel 311 also drives the connector 32 to rotate at the nut 212. By changing the reserved height of the connector 32, the height of the vehicle-mounted equipment can be adjusted. By setting a positive electrode plate and a baffle plate on the conductive ring 22, the positive electrode plate and the card are engaged in the positive electrode slot. It can not only be connected to the vehicle power supply, but also, because there is a large friction between the bottom end of the steering column and the conductive ring 22 when the steering column rotates, the conductive ring 22 has a tendency to rotate. The baffle plate and the positive electrode plate can prevent the conductive ring 22 from rotating, thereby ensuring the stability of the structure and the integrity of the function.

[0039] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
