Description

Technical Field

[0001] The present invention relates to the technical field of juice production, and in particular to a circular axis rotating DMS vehicle-mounted module structure. Background Art

[0002] As vehicles become more intelligent, DMS (Directional Monitoring System) modules have become a key component in ensuring driving safety. By monitoring driver fatigue, distraction, and other conditions in real time, they effectively reduce the probability of traffic accidents. However, existing DMS modules have numerous shortcomings regarding angle adjustment.

[0003] The rotating structure of traditional modules often uses a complex linkage mechanism or multi-joint combination, resulting in a bloated structure, large space occupation, low transmission efficiency, prone to wear and jamming, and difficult to achieve precise angle adjustment.

[0004] Although some modules use a shaft structure, the shaft design lacks targeted optimization and cannot meet the diverse usage requirements of DMS modules in terms of rotation accuracy, stability, and load capacity. This makes it difficult for monitoring equipment such as cameras to stably and comprehensively capture driver information, affecting the monitoring effect and equipment life. Therefore, a circular shaft rotating DMS vehicle-mounted module structure is proposed. Summary of the Invention

The free end of the secondary rotating circular axis is installed with a DM monitoring module, and the DM monitoring module has a built-in intelligent control unit.

[0006] Furthermore, it also includes a rotation limit assembly, which consists of a horizontal limit switch arranged on the mounting base and a limit ring installed on the secondary rotating shaft. The limit ring is rotatably connected to the top ball of the main rotating shaft. The interior of the limit ring is provided with a limit ring lining that is pressed against the top ball of the main rotating shaft. The bottom of the limit ring lining is provided with an annular groove distributed in a T shape. The annular groove is rotatably connected to the horizontal axis fixed to the surface of the top ball of the main rotating shaft. The horizontal limit switch is set at the extreme angle position of the rotation path of the main rotating shaft, and at least one horizontal limit switch is set.

[0007] Furthermore, vertical limit blocks are provided on the limit ring at both ends corresponding to the rotation range of the secondary rotating shaft.

[0008] Furthermore, a motor mounting bracket, a bearing mounting hole and a driving device for driving the main rotating shaft to rotate are also provided on the mounting base.

[0009] Furthermore, a plurality of mounting holes are provided at the bottom of the mounting base, and a wire trough is provided inside the mounting base.

[0010] Furthermore, the DMS monitoring module includes a circuit board, a high-definition camera, an infrared sensor, a millimeter-wave radar, a signal processing chip, a lower cover and an upper cover. The lower cover and the upper cover are combined together, and the lower cover is fixed to the free end installed on the limit ring. The circuit board, the high-definition camera, the infrared sensor, the millimeter-wave radar and the signal processing chip are installed inside the lower cover and the upper cover.

[0011] Furthermore, a driving mechanism for driving the limiting ring to rotate is provided inside the limiting ring.

[0012] Furthermore, an anti-winding assembly is provided at the bottom end of the cable channel, and the anti-winding assembly includes an upper rotating part fixedly connected to the bottom end of the cable channel, and the bottom end of the upper rotating part is rotatably connected to a lower rotating part, and the lower rotating part is fixed to the inner wall of the mounting base through a bracket or a cross bar. The contact surfaces of the lower rotating part and the upper rotating part are both concentrically provided with a plurality of connecting grooves and a plurality of connecting protrusions, the connecting grooves and the connecting protrusions are rotatably connected, and a sealing ring is provided between the middle part of the inner part of the connecting groove and the middle part of the outer wall of the connecting protrusion, and the electrical connection surfaces of the connecting groove and the connecting protrusion are both fixedly connected with conductive rings, and a mercury layer is filled between the two interconnected conductive rings, and the bottom end of the lower rotating part and the top end of the upper rotating part are both fixedly connected with wiring jacks, and the wiring jacks are electrically connected to the conductive rings through wires.

[0013] Furthermore, the outer shell composed of the lower cover and the upper cover is made of a lightweight, high-strength aluminum alloy material, with heat dissipation fins on the surface and a micro cooling fan inside the outer shell. Beneficial effects

[0014] Compared with the existing technology, the present invention provides a main rotating shaft and a secondary rotating shaft, which enables the DMS monitoring module to achieve 360° stable rotation in the horizontal direction and 0-180° rotation in the vertical plane. A through cable channel is provided along the axial direction for passing the power line, data line and other connecting lines of the DMS monitoring module, realizing internal wiring and preventing the exposed lines from affecting the rotation movement and suffering from wear.

[0015] The rotation limit assembly consists of a horizontal limit switch arranged on a mounting base and a limit ring installed on the secondary rotating shaft; the horizontal limit switch is distributed at a specific angle position of the rotation path of the main rotating shaft. When the main rotating shaft rotates to a preset angle, the horizontal limit switch is triggered to control the drive motor to stop rotating; the setting of the limit ring lining allows the limit ring to be assembled with the ball at the top of the main rotating shaft. The main rotating shaft can be inserted from the top of the limit ring, passing through the middle of the limit ring, and making precise contact with the ball at the top of the main rotating shaft through the inner wall of the limit ring. The limit ring lining is then pressed into the interior of the limit ring from above, and at the same time, the DMS monitoring module is assembled to the top of the limit ring, and the limit ring lining is pressed against for assembly.

[0016] The DMS monitoring module is installed at the free end of the secondary rotating shaft and integrates a high-definition camera, infrared sensor, millimeter-wave radar and signal processing chip. The high-definition camera is used to collect the driver's facial image and body movement information. The infrared sensor can detect the driver's eye condition and body temperature information at night or in dimly lit environments. The millimeter-wave radar is used to monitor the driver's body posture and subtle changes in movement. The signal processing chip analyzes and processes the data collected by each sensor in real time to determine the driver's fatigue level, concentration and other status information, and transmits the processed results to the intelligent control unit via a cable through the cable channel of the main rotating shaft.

[0017] The anti-winding component can be installed at your own discretion. The anti-winding component allows the main rotating shaft to monitor the rotation range when using the horizontal limit switch, and can ensure that the power line, data line and other lines will not be knotted, entangled or twisted, so that the main rotating shaft can break the 360° rotation limit and can rotate freely; when the main rotating shaft rotates, at this time, the upper rotating part rotates together, so that the upper rotating part rotates on the top of the lower rotating part, and the connecting protrusion rotates inside the connecting groove. The two conductive rings conduct electricity through the mercury layer, so that the conductive rings will not wear out and the continuity of the electrical connection can be maintained, and the sealing ring seals at the same time.

[0038] In specific implementation, the main rotating shaft 2 is made of hollow alloy steel and is provided with a through cable channel along the axial direction for passing the power line, data line and other lines of the DMS monitoring module 5 to realize internal wiring and avoid the exposure of the line to affect the rotation movement and suffer wear.

[0039] Both ends of the main rotating shaft 2 are mounted on the mounting base through high-precision angular contact ball bearings. The outer ring of the bearing has an interference fit with the bearing mounting hole of the mounting base, and the inner ring has an interference fit with the journal of the main rotating shaft, ensuring that the main rotating shaft can achieve 360° stable rotation in the horizontal direction and can withstand large radial and axial loads.

[0040] Secondary rotating shaft 3: vertically mounted on the main rotating shaft 2, also made of alloy steel, one end of which is connected to the radial mounting hole of the main rotating shaft via a deep groove ball bearing, and the other end is used to fix the DMS monitoring module 5.

[0042] Mounting base 1: used to fix the entire module structure inside the vehicle. It has multiple mounting holes at the bottom and can be installed on the vehicle's dashboard, center console or roof through bolts, nuts and other connectors.

[0043] For further reference, Figures 1 to 12, and also includes a rotation limit assembly, which consists of a horizontal limit switch arranged on the mounting base and a limit ring 31 installed on the secondary rotating shaft 3, the limit ring 31 is rotatably connected to the top ball of the main rotating shaft 2, and the interior of the limit ring 31 is provided with a limit ring lining 32 pressed against the top ball of the main rotating shaft 2, and the bottom of the limit ring lining 32 is provided with an annular groove 33 distributed in a T shape, and the annular groove 33 is rotatably connected to the horizontal axis fixed to the surface of the top ball of the main rotating shaft 2, and the horizontal limit switch is set at the extreme angle position of the rotation path of the main rotating shaft 2, and at least one horizontal limit switch is set.

[0044] In specific implementation, the rotation limit assembly is composed of a horizontal limit switch arranged on the mounting base and a limit ring 31 installed on the secondary rotating shaft.

[0045] The horizontal limit switches are distributed at specific angle positions on the rotation path of the main rotating shaft. When the main rotating shaft rotates to a preset angle, the horizontal limit switches are triggered to control the drive motor to stop rotating.

[0046] The setting of the limiting ring lining 32 allows the main rotating shaft 2 to be inserted from the top of the limiting ring 31 when the limiting ring 31 is assembled with the ball at the top of the main rotating shaft 2, so that the main rotating shaft 2 passes through the middle of the limiting ring 31 and makes precise contact with the ball at the top of the main rotating shaft 2 through the inner wall of the limiting ring 31. Then, the limiting ring lining 32 is pressed into the interior of the limiting ring 31 from above, and at the same time, the DMS monitoring module 5 is assembled to the top of the limiting ring 31, and the limiting ring lining 32 is pressed against for assembly.

[0047] When one horizontal limit switch is installed, it is installed at the extreme angle of 360° of the rotation path of the main rotating shaft 2. At this time, the main rotating shaft 2 just rotates one full circle.

[0048] When two horizontal limit switches are installed, they are installed at the extreme angles of 0° and 180° of the rotation path of the main rotating shaft 2. At this time, the main rotating shaft 2 rotates just half a circle.

[0049] The horizontal limit switch is a push switch or a proximity switch.

[0050] The limit position of the rotation range of the main rotating shaft 2 is monitored by a horizontal limit switch.

[0052] During specific implementation, the limit ring 31 can rotate freely in the annular groove 33 of the secondary rotating shaft 3, and vertical limit blocks are set on the mounting base 1 at both ends of the rotation range of the secondary rotating shaft 3. When the secondary rotating shaft 3 rotates to the limit angle, the limit ring 31 contacts the vertical limit block, limiting the secondary rotating shaft 3 from continuing to rotate.

[0053] The vertical limit block is a push switch or a proximity switch.

[0054] The extreme position of the rotation range of the auxiliary rotating shaft 3 is monitored by a vertical limit block.

[0055] For further reference, Figures 1 to 12 A motor mounting bracket, a bearing mounting hole and a driving device for driving the main rotating shaft 2 to rotate are also provided on the mounting base 1.

[0056] In specific implementation, a motor mounting bracket, a bearing mounting hole and other structures are also provided on the mounting base to provide mounting support for the drive device and the circular shaft rotating assembly.

[0057] In a specific implementation, the driving device includes a driving motor 22 and a gear ring 21 fixed inside the mounting base 1. The output end of the driving motor 22 drives the gear ring 21 to rotate through a gear. The gear ring 21 is fixed on the bottom end of the main rotating shaft 2, so that the gear ring 21 drives the main rotating shaft 2 to rotate.

[0058] For further reference, Figures 1 to 12 A plurality of mounting holes are provided at the bottom of the mounting base 1, and a wire groove is provided inside the mounting base 1.

[0059] In a specific implementation, a wire trough is provided inside the mounting base 1 for organizing and fixing the wires led out from the main rotating shaft cable channel, so that the wiring inside the vehicle is neat and orderly.

[0060] For further reference, Figures 1 to 12 The DMS monitoring module 5 includes a circuit board 51, a high-definition camera 52, an infrared sensor 53, a millimeter-wave radar 54, a signal processing chip, a lower cover 55 and an upper cover 56. The lower cover 55 and the upper cover 56 are covered together, and the lower cover 55 is fixed to the free end installed on the limit ring 31. The circuit board 51, the high-definition camera 52, the infrared sensor 53, the millimeter-wave radar 54 and the signal processing chip are installed inside the lower cover 55 and the upper cover 56.

[0061] In specific implementation, the DMS monitoring module 5 is installed at the free end of the secondary rotating shaft 3, and integrates a high-definition camera, an infrared sensor, a millimeter-wave radar and a signal processing chip.

[0062] High-definition cameras are used to collect the driver's facial images and body movement information. Infrared sensors can detect the driver's eye condition and body temperature information at night or in dimly lit environments. Millimeter-wave radars are used to monitor the driver's body posture and subtle changes in movements.

[0063] The signal processing chip analyzes and processes the data collected by each sensor in real time to determine the driver's fatigue level, concentration level and other status information, and transmits the processed results to the intelligent control unit via a cable through the cable channel of the main rotating shaft.

[0064] For further reference, Figure 13 and Figure 14 A driving mechanism for driving the limiting ring 31 to rotate is provided inside the limiting ring 31 .

[0065] During specific implementation, the limiting ring 31 of the secondary rotating shaft 3 is driven by the driving mechanism to rotate 0-180 degrees.

[0066] In the specific implementation, refer to Figure 13 and Figure 14 The driving mechanism includes two rows of parallel teeth 23 arranged on the top spherical surface of the main rotating shaft 2, two helical gears 24 are rotatably connected on the limiting ring lining 32, the two helical gears 24 are connected by a shaft, and the outer end surface edges of the two helical gears 24 are integrally connected with a meshing gear 25 that meshes with the teeth, and a servo motor 26 is fixedly connected to the limiting ring lining 32, and the output end of the servo motor 26 meshes with the two helical gears 24 through a helical gear.

[0067] During specific implementation, when the driving mechanism is working, the servo motor 26 works, and the output end of the servo motor 26 engages the helical gear 24 through the helical gear, so that the meshing gear 25 on the outer end surface edge of the helical gear 24 engages with the tooth 23, so that the limit ring 31 rotates on the top spherical surface of the main rotating shaft 2.

[0068] During specific implementation, the driving device and the driving mechanism can be replaced by similar driving mechanisms.

[0069] For further reference, Figure 16 and Figure 17The bottom end of the cable channel is provided with an anti-winding assembly 27, which includes an upper rotating member 272 fixedly connected to the bottom end of the cable channel, and a lower rotating member 271 is rotatably connected to the bottom end of the upper rotating member 272. The lower rotating member 271 is fixed to the inner wall of the mounting base 1 through a bracket or a cross bar. The contact surfaces of the lower rotating member 271 and the upper rotating member 272 are concentrically provided with a plurality of connecting grooves 274 and a plurality of connecting protrusions 275. The connecting grooves 274 and the connecting protrusions 275 is rotatably connected, and a sealing ring 278 is provided between the middle part of the inner part of the connecting groove 274 and the middle part of the outer wall of the connecting protrusion 275. The connecting groove 274 and the connecting protrusion 275 are fixedly connected to the power contact surface with a conductive ring 276, and a mercury layer 277 is filled between the two conductive rings 276 connected to each other. The bottom end of the lower rotating part 271 and the top end of the upper rotating part 272 are fixedly connected to the wiring jack 273, and the wiring jack 273 is connected to the conductive ring 276 for electrical signals through a wire.

[0070] During specific implementation, the anti-winding component 27 can be installed or not. The anti-winding component 27 enables the main rotating shaft 2 to monitor the rotation range using a horizontal limit switch, and can ensure that power lines, data lines and other lines will not be knotted, entangled or twisted, so that the main rotating shaft 2 can break through the 360° rotation limit and can rotate freely (that is, the rotation angle can be greater than 360° and less than 0°), negative two circles -720°, 0°, two circles 720°, and ten circles 3600°.

[0071] At this time, the power line, data line and other lines are plugged into the wiring jack 273 through the connector.

[0072] When the main rotating shaft 2 rotates, the upper rotating member 272 rotates along with it, so that the upper rotating member 272 rotates on the top of the lower rotating member 271, and the connecting protrusion 275 rotates inside the connecting groove 274. The two conductive rings 276 conduct electricity through the mercury layer 277, so that the conductive rings 276 will not wear out and can maintain the continuity of the electrical connection. At the same time, the sealing ring 278 performs sealing.

[0077] In specific implementation, the shell of the DMS5 monitoring module is made of lightweight, high-strength aluminum alloy, with heat dissipation fins on the surface, combined with the internal micro cooling fan to improve heat dissipation efficiency and ensure the stability of the module under long-term operation.

[0078] According to the actual layout and usage requirements of the vehicle interior, select a suitable installation location, such as the center position above the instrument panel; fix the mounting base 1 to the selected installation location by passing the bolts through the mounting holes at the bottom to ensure that the installation is firm; install the main rotating shaft 2, press the high-precision angular contact ball bearings into the bearing mounting holes of the mounting base, and then insert the two ends of the main rotating shaft into the corresponding bearing inner rings so that the main rotating shaft can rotate flexibly; install the deep groove ball bearing in the radial mounting hole of the main rotating shaft 2, and insert one end of the secondary rotating shaft into the bearing inner ring so that the secondary rotating shaft can rotate freely in the vertical direction; install the limit ring on the ball of the main rotating shaft 2, and install vertical limit blocks on the mounting base 1 at both ends of the rotation range of the secondary rotating shaft, and adjust the position to ensure accurate limit; install the DMS monitoring module 5 on the free end of the secondary rotating shaft 3 and fix it firmly with bolts and other connecting parts; pass the power line, data line and other lines of the DMS monitoring module 5 through the cable channel of the main rotating shaft 2 and connect them to the intelligent control unit.
