Description

Technical Field

[0001] The present invention relates to the field of power supply for vehicle-mounted devices, and particularly to a fastening power interface for vehicles. Background Art

[0002] In the current automotive field, with the diversification and intelligent development of vehicle-mounted device functions, users' demand for convenient power supply is increasing day by day. However, traditional power supply methods such as external power cords have problems such as messy wiring, poor aesthetics, and inconvenient use. For example, devices such as mobile phone holders, action cameras, and air purifiers usually need to be powered by external power cords, which not only affects the neatness inside the vehicle but also makes carrying cumbersome, ultimately making it cumbersome to obtain power for vehicle-mounted devices. Summary of the Invention

[0003] The present invention aims to provide a fastening power interface for vehicles to solve the problem of cumbersome power acquisition for vehicle-mounted devices.

[0004] To achieve the above object, the present invention adopts the following technical solution: A fastening power interface for vehicles includes a housing. The housing is provided with a fixing component for connecting to a vehicle power supply. The housing is detachably connected with a connecting component for connecting to a vehicle-mounted device through the fixing component. The connecting component includes a connecting shell. The connecting component further includes a connecting piece and an elastic piece for connecting the fixing component and the two levels of the vehicle-mounted device power supply. The connecting piece is slidably connected to the connecting shell. The elastic piece is elastically connected to both ends of the connecting shell and penetrates through the connecting shell. The housing is provided with a first connecting hole for the connecting piece to pass through. The connecting piece is used to pass through the first connecting hole and connect to the fixing component.

[0005] The beneficial effects of this solution are as follows: During use, first connect the fixing component to the vehicle power supply lamp, and fixedly connect the housing to the vehicle body. Subsequently, fixedly connect the connecting component to the housing through the fixed connection between the connecting piece and the fixing component. At this time, the connecting component is connected to the positive and negative poles of the vehicle power supply through the fixing component. Then, connect the vehicle-mounted device to the end of the connecting piece away from the fixing component. The vehicle-mounted device is connected to the vehicle power supply through the connecting component. Since the connecting piece is slidably arranged on the connecting component and the elastic piece is elastically connected, the connecting piece and the elastic piece are respectively connected to the negative pole and the positive pole of the vehicle power supply through the fixing component. When the vehicle-mounted device is connected to the connecting component, it is connected through the top end of the connecting piece and the top end of the elastic piece, thereby realizing the electrical connection between the vehicle-mounted device and the vehicle power supply. Compared with the prior art, there is no need for a data cable, which is convenient to carry during user use and is also convenient and fast to install during installation. Therefore, the purpose of convenient installation of vehicle-mounted devices can be achieved.

[0006] By slidably connecting the connecting member to the connecting shell and elastically connecting the elastic member to the connecting shell, when it is necessary to adjust the height or angle of the vehicle-mounted device, relative rotation or relative sliding will occur between the connecting member and the vehicle-mounted device and between the connecting member and the fixing component. Since the installation position reserved for the elastic member is limited, for the bottom end of the vehicle-mounted device, for a small height change, when the vehicle-mounted device rises a small distance, the elastic member will naturally stretch, ensuring that the upper and lower ends of the elastic member are always in contact with the vehicle-mounted device and the fixing component respectively. When the vehicle-mounted device descends a small distance, the elastic member will be slightly bent under pressure, also to ensure that the upper and lower ends of the elastic member are in contact with the vehicle-mounted device and the fixing component respectively. Therefore, it can achieve the purpose that the elastic member can always ensure the electrical connection between the vehicle-mounted power supply and the vehicle-mounted device when the vehicle-mounted device is adjusted in angle and height, and thus can achieve the fine adjustment of the vehicle-mounted device.

[0007] On the other hand, when the reserved lengths of the connecting member at the connection port at the bottom end of the vehicle-mounted device are different, it is necessary to adjust the reserved length of the connecting member at the shell according to the actual situation of the vehicle-mounted device to be installed before connecting the connecting component to the shell, so as to avoid adjusting the device after installation. Therefore, it can meet the installation of a variety of different vehicle-mounted devices. Compared with the prior art, not only can a variety of different vehicle-mounted devices be installed, but also the installed vehicle-mounted device can be finely adjusted.

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

[0009] The beneficial effect of this solution is that when installing the connecting component and the shell, the bottom end of the connecting component is embedded in the connection groove. The connecting member penetrates through the shell through the first connection 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 connection groove, and since the elastic member protrudes and is connected to the upper and lower ends of the connection shell, the elastic member abuts against the conductive ring at the bottom end of the connection groove through the connection shell. It can not only realize the connection of the connecting component to the vehicle-mounted power supply through the fixing component, but also achieve the purpose of fixing the connecting member to the shell through the fixing member.

[0010] Preferably, as an improvement, corresponding threaded holes are provided on both sides of the conductive plate and the shell. The conductive plate is provided with a second connection hole for the connecting member to penetrate, and a fixing member for fixing the connecting member is fixedly arranged at the second connection hole of the conductive plate.

[0011] The beneficial effects of this solution are as follows: By providing threaded holes, the conductive plate can be installed at the bottom of the housing using screws, thus achieving a detachable connection of the conductive plate. In addition, the connecting member is connected to the fixing member through the second connecting hole to achieve power connection.

[0012] Preferably, as an improvement, the connecting member is provided in a rod shape, and a screw rod is provided at the bottom end of the connecting member, and the fixing member is provided as a nut.

[0013] The beneficial effects of this solution are as follows: The bottom end of the connecting member is threadedly connected to the nut. When the angle of the vehicle-mounted device needs to be adjusted, the connecting member rotates through the screw rod, which will inevitably drive the vehicle-mounted device to move in the height direction. When the height needs to be adjusted, fine adjustment can also be achieved by rotating the angle.

[0014] Preferably, as an improvement, the connecting shell includes a connecting column and a rotating wheel fixed to the outer circle of the top end of the connecting column. A sliding cavity is provided inside the connecting column. A slider is fixed to the outer circle of the connecting member. The horizontal cross-sections of the slider and the moving cavity are both polygons with equal sizes and the same shapes, 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 providing the slider, on the one hand, the slider can be guided and slid in the inner cavity of the connecting column. On the other hand, since the cross-sections of the sliding block and the inner cavity of the connecting column are both polygons, and the structures and sizes are equal, the inner cavity of the connecting column has a rotational limiting effect on the slider. By rotating the connecting shell through the rotating wheel, the inner cavity of the connecting column drives the connecting member to rotate together. After the rotation, the angle adjustment is completed. At this time, the height of the connecting member changes, and the connecting member generates a relative displacement in the inner cavity of the connecting column through the guidance of the slider. The vehicle-mounted device after the height change realizes power connection through the automatic adjustment of the elastic member.

[0016] Preferably, as an improvement, an adjustment cavity for installing the elastic member is provided on the outer circle of the connecting column, and an installation cavity for installing the elastic member is provided on the rotating wheel. The adjustment cavity is communicated with the installation cavity, and the elastic member 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 member has a certain elasticity, and the thicknesses of the adjustment cavity and the installation cavity are greater than the thickness of the elastic member, the elastic member has a certain deformation space in the adjustment cavity and the installation cavity and can be accommodated when the elastic member is compressed and bent.

[0018] Preferably, as an improvement, the conductive ring and the conductive plate are respectively used to connect the positive and negative poles of the vehicle-mounted power supply, and the two ends of the elastic member are respectively used to abut against the conductive ring and the positive pole of the vehicle-mounted device.

[0019] The beneficial effects of this solution are as follows: The elastic member is connected to the positive electrode, and the connecting member is connected to the negative electrode through a screw and a nut. During the installation process, the connecting component is first placed in the connecting groove, and then the rotating wheel is rotated to drive the connecting rod to be connected to the fixing component. The step of connecting the power supply is that the positive electrode is connected before the negative electrode; when it is necessary to disassemble the connecting component from the housing, rotate the rotating wheel, and the rotating wheel drives the connecting member to rotate, so that the screw at the bottom end of the connecting member is first disconnected from the nut. After disconnection, the connecting shell is still placed in the connecting groove, and finally it is taken out. At this time, the step of disconnecting the power supply is that the negative electrode is disconnected before the positive electrode. Because in the automotive circuit design, the negative electrode is usually connected to the vehicle body to form a grounding system. Therefore, disconnecting the negative electrode first can avoid the risk of short circuit between the positive and negative electrodes and reduce the possibility of electric shock.

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

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

[0022] Preferably, as an improvement, the nut, the connecting member, and the elastic member are all made of conductive materials.

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

[0024] The beneficial effects of this solution are as follows: When the connecting shell is embedded in the connecting groove, it is the connecting column at the bottom end that is embedded in the connecting groove. Since the elastic member is provided on the outer ring of the connecting column, when there is a gap between the outer ring of the connecting column and the inner ring of the connecting groove, it can ensure that there is also a space for the elastic member to bend and deform between the two.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The following is a more detailed description through specific embodiments: The reference numerals in the attached drawings of the specification include: housing 1, first connection hole 11, connection groove 12, annular groove 121, first convex ring 122, fixing assembly 2, conductive plate 21, second connection hole 211, nut 212, conductive ring 22, connection assembly 3, connection housing 31, runner 311, installation cavity 3111, second installation gap 3112, connection post 312, adjustment cavity 3121, second convex ring 3122, adjustment plate 3123, first installation gap 3124, connecting member 32, slider 321, elastic member 33.

[0027] Embodiment A fastening power interface for vehicle-mounted use, as Figure 1 , Figure 3 shown, includes a housing 1 for fixedly connecting to the vehicle body. The housing 1 is made of non-conductive material. A connection groove 12 is formed at the top end of the housing 1. The connection groove 12 is arranged in a frustum shape with a larger top and a smaller bottom. A first connection hole 11 is formed at the bottom end of the connection groove 12 on the housing 1. The first connection hole 11 penetrates through the bottom end of the housing 1. The diameter of the first connection hole 11 is smaller than the diameter of the bottom surface of the connection groove 12. An annular groove 121 is formed at the outer circle of the bottom end of the connection groove 12. The diameter of the annular groove 121 is smaller than the diameter of the lower bottom surface of the connection groove 12 and larger than the diameter of the first connection hole 11. The annular groove 121, the upper and lower bottom surfaces of the connection groove 12, and the first connection hole 11 are all coaxially arranged. At the bottom end of the connection groove 12, a first convex ring 122 protruding upward is formed between the annular groove 121 and the first connection hole 11. The first convex ring 122 is arranged upward. A conductive ring 22 is embedded in the annular groove 121. Therefore, the conductive ring 22 is located between the outer circle of the convex ring and the inner circle of the bottom end of the connection groove 12. A positive electrode plate and a retaining piece are integrally arranged on both sides of the conductive ring 22 respectively. Positive electrode card slots for the positive electrode plate to pass through are symmetrically formed on both sides of the bottom end of the housing 1 at the bottom end of the connection groove 12. The conductive ring 22 contacts the positive power supply of the vehicle-mounted power supply through the positive electrode plate.

[0028] As Figure 1 , Figure 4 shown, a conductive plate 21 is detachably connected to the bottom end of the housing 1. The conductive plate 21 is provided with a second connection hole 211 corresponding to the first connection hole 11. A negative electrode plate is integrally arranged on the conductive plate 21. The negative electrode plate is used to connect to the negative pole of the vehicle-mounted power supply. A nut 212 is fixedly welded at the second connection hole 211 at the bottom end of the conductive plate 21. Both ends of the nut 212 are open, which is convenient for threaded connection during connection. Threaded holes are formed on both sides of the conductive plate 21. Threaded holes corresponding to the threaded holes on the conductive plate 21 are also formed at the bottom end of the housing 1. During installation, the conductive plate 21 is threadedly connected to the bottom end of the housing 1 through screws, thereby realizing the detachable connection of the conductive plate 21.

[0029] As Figure 2 , Figure 4As shown, it further includes a connection component 3. The connection component 3 includes a connection shell 31. The connection shell 31 includes a runner 311 at the top and a connection column 312 fixed to the bottom end of the runner 311. The connection column 312 is integrally provided with the runner 311. A number of anti-slip lines are vertically arranged on the outer circle of the runner 311. By manually driving the runner 311 to rotate, the runner 311 drives the connection column 312 to rotate. Adjustment cavities 3121 are symmetrically opened on both sides of the outer circle of the connection column 312. The adjustment cavities 3121 are vertically opened. Installation cavities 3111 are also symmetrically opened on both sides of the runner 311. The installation cavities 3111 correspond to and communicate with the adjustment cavities 3121 one by one. At the bottom end of the connection column 312, a second convex ring 3122 is coaxially arranged with the connection column 312. The second convex ring 3122 has an opening facing downwards. The second convex ring 3122 corresponds to and has the same diameter as the second connection hole 211. An adjustment plate 3123 is arranged on the vertical plane of the adjustment cavity 3121. The bottom end of the adjustment plate 3123 is higher than the height of the second convex ring 3122. There is a first installation gap 3124 between the adjustment plate 3123 and the second convex ring 3122. The first installation gap 3124 is vertically arranged with respect to the adjustment plate 3123. The installation cavities 3111 are vertically opened, and a second installation gap 3112 is horizontally opened at the top end of the installation cavities 3111. The first installation gap 3124, the adjustment cavity 3121, the installation cavity 3111, and the second installation gap 3112 together form an installation position for installing an elastic member 33. The elastic member 33 is a conductive elastic sheet composed of a conductive material. The conductive elastic sheet includes a vertical part and buckling parts perpendicular to the vertical part up and down. During installation, the upper and lower ends of the conductive elastic sheet are respectively buckled in the second installation gap 3112 and the first installation gap 3124, and the vertical part is placed in the vertical space formed by the adjustment cavity 3121 and the installation cavity 3111. There is also a gap between the outer circle of the connection column 312 and the inner wall of the connection groove 12.

[0030] As Figure 4 - Figure 5As shown in the figure, the second convex ring 3122 of the connecting column 312 after installation abuts against the first convex ring 122 at the bottom end of the connecting groove 12. At the same time, since the adjusting plate 3123 is located on the outer ring of the second convex ring 3122 and the elastic member 33 is installed in the installation position composed of 'the first installation position - the adjusting cavity 3121 - the installation cavity 3111 - the second installation position', the bottom end of the elastic member 33 winds around the bottom end of the adjusting plate 3123. Therefore, the adjusting plate 3123 presses the elastic member 33 against the conductive ring 22, making the conductive ring 22 and the elastic member 33 electrically connected. There is a small gap between the bottom end of the elastic member 33 and the bottom end face of the adjusting plate 3123, and the top end is in the second installation gap 3112. The elastic member 33 is horizontally arranged, and there is also a gap between the second installation position and the horizontal end of the elastic member 33. For the elastic member 33, when it is installed in the connecting component 3 and placed in the connecting groove 12, there are gaps between the elastic member 33 and the adjusting plate 3123, between the outer circle of the connecting column 312 and the inner circle of the connecting groove 12, and between the horizontal end of the elastic member 33 and the second installation gap 3112. In addition, the vertical part of the elastic member 33 is located in the adjusting cavity 3121 and the installation cavity 3111. Therefore, when the in-vehicle device rotates and adjusts downward, the in-vehicle device drives the runner 311 to move downward. At this time, the elastic member 33 is pressed and bent, and can also be compressed so that there is no gap between the horizontal end face of the elastic member 33 and the second installation gap 3112, or the elastic member 33 is closely attached to the bottom end of the adjusting plate 3123. In this way, when the runner 311 moves downward, it can still ensure that the positive pole of the in-vehicle power supply is not disconnected, thus achieving the fine-tuning purpose of the in-vehicle device.

[0031] As Figure 4 - Figure 5 shown, a connecting member 32 is vertically slidably arranged in the connecting column 312. The connecting member 32 is also made of conductive material. In this embodiment, the connecting member 32 is arranged in a rod shape, and the bottom end of the connecting member 32 is set as a screw. The inner cross-section of the connecting column 312 is set as a polygon. A slider 321 is fixedly arranged coaxially with the outer circle of the connecting member 32. The cross-sectional shape of the slider 321 is a polygon congruent to the inner cross-section of the connecting column 312. The slider 321 is embedded in the inner cavity of the connecting column 312, and several side faces of the slider 321 are tangent to the inner circle of the connecting column 312. The connecting column 312 is used to vertically guide the connecting member 32 through the slider 321. When connecting, the connecting column 312 is placed in the connecting groove 12, and the runner 311 is rotated. The runner 311 drives the connecting member 32 to rotate. The connecting member 32 penetrates through the first connecting hole 11 and the second connecting hole 211 and is threadedly connected with the nut 212. The top end of the rod-shaped connecting member 32 can be provided with various forms of connecting heads to connect with the negative pole of the in-vehicle power supply. In this embodiment, the connecting member 32 is set as a double-headed screw. Therefore, the in-vehicle device is also connected to the top end of the connecting member 32 through the reserved threaded hole to achieve the connection of the negative pole.

[0032] Its working principle is as follows: When the angle of the in-vehicle device 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 in-vehicle device moves in the vertical direction under the drive of the connecting member 32. When the in-vehicle device moves downward, the elastic member 33 is squeezed and bent. When the in-vehicle device moves upward, the elastic member 33 returns to its original shape. The elastic member 33 can only meet a certain height adjustment of the in-vehicle device, which is commonly known as fine-tuning. However, for a large height adjustment, the rotating wheel 311 needs to be continuously rotated. The rotating wheel 311 also drives the connecting member 32 to rotate at the nut 212, and a large height adjustment of the in-vehicle device is achieved by changing the reserved height of the connecting member 32. By providing a positive electrode piece and a retaining piece on the slip ring 22, the positive electrode piece and the card are clamped in the positive electrode card slot, which can not only be connected to the in-vehicle power supply, but also because there is a large friction between the bottom end of the steering column and the slip ring 22 when the steering column rotates, so the slip ring 22 has a tendency to rotate. The retaining piece and the positive electrode piece can prevent the slip ring 22 from rotating, thus ensuring the stability of the structure and the integrity of the function.

[0033] The above are only embodiments of the present invention, and common general technical solutions and / or characteristics in the solutions are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
