Description

Technical Field

[0001] This utility model belongs to the technical field of automotive testing auxiliary equipment, specifically relating to a liftable adjustable sunshade for automotive assisted driving calibration testing. Background Technology

[0002] In the calibration and testing of automotive driver assistance systems (such as ADAS), it is necessary to control the amount of light transmitted through the vehicle's glass using a light-blocking curtain to simulate different lighting environments and thus test the response performance of the vehicle's sensors. However, existing automotive driver assistance calibration and testing equipment often uses light-blocking curtains with a left-right opening or single-sided left-right sliding structure. With this structure, the curtain fabric is prone to large-area wrinkles due to uneven stress, which not only reduces the lifespan of the curtain but also affects its light-blocking effect. Furthermore, traditional light-blocking curtains with this structure have a fixed light-blocking height, making it impossible to adjust vertically according to the glass size of different vehicle models (such as sedans, SUVs, and trucks), hindering precise control of the light-blocking area and affecting the accuracy of calibration and testing.

[0003] Therefore, there is an urgent need for a highly adjustable, adaptable, and automated adjustable sunshade for automotive driver assistance calibration and testing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a liftable adjustable sunshade for automotive assisted driving calibration and testing, which solves the problems of limited applicability and easy wrinkling of existing sunshades in automotive assisted driving calibration and testing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a liftable adjustable sunshade for automotive assisted driving calibration and testing, comprising a roller, a curtain, a crossbeam, and a bearing seat and a motor mounting seat disposed on the crossbeam;

[0006] The two ends of the roller are rotatably connected to the bearing seat and the motor mounting seat, respectively, and the motor mounting seat is provided with a servo motor for driving the roller to rotate.

[0007] One end of the curtain is fixedly connected to the outer periphery of the roller along the axial direction, and the other end of the curtain is provided with a counterweight rod along the axial direction of the roller.

[0008] Optionally, the roller includes a first shaft disk rotatably connected to the bearing seat and a second shaft disk rotatably connected to the motor mounting seat. A plurality of inner support rods arranged in a circular array are provided between the first shaft disk and the second shaft disk along their rotation axis. An arc-shaped surrounding plate with its center coinciding with the central axis of the array is connected between two adjacent inner support rods.

[0009] Optionally, the first shaft disk includes a first mounting disk and a first drive shaft detachably connected to the first mounting disk, and the second shaft disk includes a second mounting disk and a second drive shaft detachably connected to the second mounting disk;

[0010] The first mounting plate and the second mounting plate are provided with a recessed positioning groove on one side for embedding the end of the inner support rod, and the first shaft plate and the second shaft plate are provided with a number of fastening bolts that can be threaded to the end of the inner support rod.

[0011] Optionally, a deep groove ball bearing is fitted around the outer periphery of the first drive shaft, the inner ring of the deep groove ball bearing is transition-fitted with the outer periphery of the first drive shaft, and the outer ring of the deep groove ball bearing is press-fitted into the first bearing hole on the bearing housing.

[0012] Optionally, a retaining ring is embedded in the outer periphery of a section of the first drive shaft passing through the deep groove ball bearing.

[0013] Optionally, a self-aligning ball bearing is fitted around the outer periphery of the second drive shaft, the inner ring of the self-aligning ball bearing is transitionally fitted with the outer periphery of the second drive shaft, and the outer ring of the self-aligning ball bearing is press-fitted into the second bearing hole on the motor mounting base.

[0014] Optionally, a driven wheel is provided on the outer periphery of a section of the second drive shaft passing through the second bearing hole, and a driving wheel is provided on the outer periphery of the output shaft of the servo motor. The driving wheel and the driven wheel are connected by a belt drive.

[0015] Optionally, flange connecting plates are provided on the bottom sides of both ends of the crossbeam.

[0016] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: When the servo motor drives the roller to rotate, the curtain fabric wound on the roller can fall under its own weight and the weight of the counterweight rod. The height of the curtain fabric falling can be freely adjusted by the servo motor, so that the area of ​​light blocking by the curtain fabric can be adjusted according to different vehicle models, ensuring the light-blocking effect of the blackout curtain. At the same time, the weight of the counterweight rod will apply a continuous downward force to the curtain fabric, and the force can be kept uniform during the unfolding or winding of the curtain fabric, which can effectively avoid the problem of large-area wrinkles caused by uneven force on the curtain fabric.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] like Figures 1-3As shown, a liftable adjustable sunshade for automotive assisted driving calibration and testing includes a roller 1, a curtain 2, a crossbeam 3, and a bearing seat 4 and a motor mounting seat 5 disposed on the crossbeam 3. The two ends of the roller 1 are rotatably connected to the bearing seat 4 and the motor mounting seat 5, respectively, and a servo motor 6 for driving the roller 1 to rotate is disposed on the motor mounting seat 5. One edge of the curtain 2 is fixedly connected to the outer periphery of the roller 1 along the axial direction of the roller 1, and a counterweight rod 7 is disposed at the other end of the curtain 2 along the axial direction of the roller 1.

[0025] Specifically, the crossbeam 3 can be installed above other components (such as columns, brackets, accessories, etc.), allowing the curtain 2, wound on the roller 1, to be suspended above the calibration and detection area. The servo motor 6 has a self-locking function. When the servo motor 6 drives the roller 1 to rotate, the curtain 2 wound on the roller 1 can fall under its own weight and the weight of the counterweight 7. The height of the curtain 2 can be freely adjusted by the servo motor 6, so that the area shaded by the curtain 2 can be adjusted according to different vehicle models, ensuring the shading effect of the blackout curtain. It should be noted that during this process, the weight of the counterweight 7 will exert a continuous downward force on the curtain 2. The curtain 2 can maintain uniform force during unfolding or winding, which can effectively avoid the problem of large-area wrinkles caused by uneven force on the curtain 2.

[0026] The above, such as Figure 3 As shown, the roller 1 includes a first shaft disk rotatably connected to the bearing seat 4 and a second shaft disk rotatably connected to the motor mounting seat 5. A plurality of inner support rods 101 arranged in a circular array are disposed between the first and second shaft disks along their rotation axis. An arc-shaped surrounding plate 102, whose center coincides with the central axis of the array, connects adjacent inner support rods 101. The roller 1 adopts an assembled structure, which not only reduces costs but also reduces the weight of the roller 1, thus reducing the load on the servo motor 6.

[0027] Furthermore, such as Figure 3 As shown, the first shaft disk includes a first mounting disk 103 and a first drive shaft 104 detachably connected to the first mounting disk 103, and the second shaft disk includes a second mounting disk 105 and a second drive shaft 106 detachably connected to the second mounting disk 105. The first drive shaft 104 and the first mounting disk 103, and the second drive shaft 106 and the second mounting disk 105, can be detachably connected by one or more of the following connection methods: key connection (with fasteners), flange connection, expansion sleeve connection, threaded connection, pin connection, etc.

[0028] The first mounting plate 103 and the second mounting plate 105 have recessed positioning grooves on one side for embedding the end of the inner support rod 101, which are used to position the assembly position of the inner support rod 101. Several fastening bolts that can be threaded onto the first and second shaft plates are movably inserted into the first and second shaft plates, enabling a detachable connection between the inner support rod 101 and the first and second shaft plates, thereby reducing equipment maintenance costs.

[0029] Furthermore, in this embodiment, to ensure the smoothness of the winding and unwinding of the curtain fabric 2, a deep groove ball bearing 8 is fitted around the outer periphery of the first drive shaft 104. The inner ring of the deep groove ball bearing 8 is transitionally fitted with the outer periphery of the first drive shaft 104, and the outer ring of the deep groove ball bearing 8 is press-fitted into the first bearing hole 401 on the bearing seat 4. A self-aligning ball bearing 10 is fitted around the outer periphery of the second drive shaft 106. The inner ring of the self-aligning ball bearing 10 is transitionally fitted with the outer periphery of the second drive shaft 106, and the outer ring of the self-aligning ball bearing 10 is press-fitted into the second bearing hole 501 on the motor mounting base 5.

[0030] It is important to note that, such as Figure 3 As shown, a retaining ring 9 is embedded in the outer periphery of a section of the first drive shaft 104 passing through the deep groove ball bearing 8 to limit the axial displacement of the deep groove ball bearing 8. Meanwhile, a driven wheel 11 is provided on the outer periphery of a section of the second drive shaft 106 passing through the second bearing hole 501, and a driving wheel 12 is provided on the outer periphery of the output shaft of the servo motor 6. The driving wheel 12 and the driven wheel 11 are driven and connected by a belt 13. The driven wheel 11 and the second drive shaft 106, and the driving wheel 12 and the output shaft of the servo motor 6, can be locked together by a key.

[0031] Furthermore, such as Figure 1 , Figure 3 As shown, in this technical solution, flange connecting plates 14 are provided on the bottom sides of both ends of the crossbeam 3. The flange connecting plates 14 are used to achieve reliable connection between the crossbeam 3 and other components (such as columns, supports, accessories, etc.). Specifically, the flange connecting plates 14 are welded to the bottom sides of the ends of the crossbeam 3, and stiffening plates are also welded between the flange connecting plates 14 and the crossbeam 3 to optimize the stress distribution when the crossbeam 3 is installed on other components and to improve the stability of the overall structure.

[0032] Working principle: The crossbeam 3 can be installed above other components (such as columns, brackets, accessories, etc.) via the flange connection plate 14, allowing the curtain 2 wound on the roller 1 to be suspended above the calibration and detection area. The servo motor 6 has a self-locking function. When the servo motor 6 drives the roller 1 to rotate, the curtain 2 wound on the roller 1 can fall down under its own weight and the weight of the counterweight rod 7. The height of the curtain 2 can be freely adjusted by the servo motor 6, so that the area of ​​light blocking by the curtain 2 can be adjusted according to different vehicle models, ensuring the light blocking effect of the light-blocking curtain.

[0033] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
