Description

Technical Field

[0001] This utility model relates to the field of vehicle inspection technology, specifically to a sunlight simulation system mounting base and a sunlight simulation system. Background Technology

[0002] Aging tests of whole vehicles or components are one part of vehicle inspection. Traditionally, the assessment of the aging of whole vehicles is mainly based on natural exposure tests conducted in outdoor exposure fields. This can realistically assess the impact of the outdoor natural environment on vehicle aging, but the test cycle is long, generally 1 to 2 years, which cannot meet the needs of car companies to quickly develop new models.

[0003] To address the aforementioned issues, a test chamber with a sunlight simulation system has been designed. This system uses artificially controlled lighting to accelerate vehicle aging within the chamber, thereby shortening the aging test time. A sunlight simulation system typically includes an array of lights providing illumination and a winch connected to the array via steel cables. Adjusting the height of the light array using the winch can meet different lighting requirements. However, this lifting and lowering scheme has a bulky overall structure and high equipment costs. Patent application CN202122437688.8 discloses a sunlight simulation system for a whole-vehicle environmental test chamber, which includes a screw jack with a lead screw. The lower end of the lead screw is fixedly connected to the light array, and the lead screw moves up and down driven by the screw jack, thus raising and lowering the light array. While this technical solution utilizes a winch, overcoming some of the drawbacks of winch-based lifting and lowering, its limitation by the lead screw structure restricts it to vertical lifting only, preventing flexible adjustment of the light array's illumination angle and thus limiting the functionality of the sunlight simulation system. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a light array mounting base that can be used to connect light arrays and enable their raising and lowering. Compared to existing technologies, its overall structure is lighter and allows for more flexible adjustments to the light array.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A light array mounting base includes a support frame, a drive mechanism, and several sets of lifting mechanisms. Each lifting mechanism includes a screw jack, a directional guide rail, a connecting block, and a set of guide wheels. The screw jack includes a transmission chamber and a laterally arranged lead screw connected to the transmission chamber. The extension direction of the directional guide rail is parallel to the axial direction of the lead screw. The connecting block is fixedly connected to the end of the lead screw and movably engages with the directional guide rail. A rope connection portion is provided on the side of the connecting block near the transmission chamber. The drive mechanism includes a drive motor and a transmission component controlled by the drive motor. The transmission component is connected to the transmission chamber and is used to drive the lead screw to move laterally.

[0007] Furthermore, the support frame includes four rectangular mounting corners, each of which is equipped with a set of the lifting mechanisms.

[0008] Furthermore, the lead screws contained in several sets of lifting mechanisms are arranged parallel to each other.

[0009] Furthermore, the transmission component includes a first transmission rod, a second transmission rod, and a steering gear. The steering gear includes an input connector and two output connectors facing opposite directions. The input connector is connected to a drive motor via a first transmission rod, and each output connector is connected to a transmission housing via a second transmission rod.

[0010] Furthermore, the axis of the lead screw coincides with the rotation plane of the corresponding guide wheel assembly.

[0011] Furthermore, the guide wheel assembly includes a longitudinal guide wheel and a transverse guide wheel, with the transverse guide wheel positioned above the longitudinal guide wheel and relatively close to the corresponding connecting block.

[0012] Furthermore, the lead screw is provided with a limiting component for limiting its own travel range.

[0013] Furthermore, a protective sleeve is provided on the non-travel portion of the lead screw.

[0014] Furthermore, the support frame is also connected to a hoisting fixing rod perpendicular to the lead screw.

[0015] Another objective of this utility model is to provide a sunlight simulation system, which includes a light array, a suspension rope, and the aforementioned light array mounting base. The middle part of the suspension rope cooperates with the guide wheel assembly, and the first end of the suspension rope is longitudinally connected to the light array, and the second end is transversely connected to the rope connection part.

[0016] The following beneficial effects can be achieved by applying this utility model:

[0017] 1. This utility model controls the lifting and lowering of the light array by using a horizontally arranged lead screw. Under the control of the drive motor, the connecting block at the end of the lead screw moves towards or away from the guide wheel assembly. When the connecting block is close to the guide wheel assembly, the height of the light array connected to the connecting block by the rope decreases. When the connecting block is away from the guide wheel assembly, the height of the light array increases, thereby achieving height control of the light array. Compared with the existing hoisting scheme, this utility model has a lighter structure and only requires fixing the support frame during installation, making installation more convenient.

[0018] 2. This utility model controls the raising and lowering of the light array through a screw-driven and rope-lifting scheme. Different lifting mechanisms can control the raising and lowering of different parts of the light array. Compared with the direct screw-lifting scheme, this utility model can make different parts of the light array have different raising and lowering heights, thereby causing the illumination angle of the light array to tilt, thus meeting different lighting simulation needs and expanding the testing function of the sunlight simulation system.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example

[0025] Reference Figures 1-3 This embodiment provides a lamp array mounting base, which can be used to install the lamp array of the sunlight simulation system in the vehicle accelerated aging test. The height and angle of the lamp array can be changed to adapt to different test requirements.

[0026] The lamp array mounting base includes a support frame 1, a drive mechanism, and four lifting mechanisms;

[0027] The support frame 1 is used to provide installation sites for other device structures. The support frame is roughly rectangular in shape when viewed from above. Each of the four corners of the rectangular structure is provided with a hoisting and fixing rod 11. The hoisting and fixing rod is used to fix the support frame in the predetermined position of the solar simulation test chamber.

[0028] The four lifting mechanisms are respectively located at the four corners of the support frame, used to connect the light array of the sunlight simulation system and drive the light array to move in the height direction. Each lifting mechanism includes a screw jack 4, a directional guide rail 5, a connecting block 6, and a guide wheel set 7. The screw jack includes a transmission chamber 41 and a lead screw 42 that is connected to the transmission chamber and arranged laterally. When the turbine assembly in the transmission chamber rotates, the lead screw that cooperates with the turbine assembly will move axially relative to the transmission chamber. Typically, the support frame has one long side and one short side, and the direction of the lead screw is parallel to the long side of the support frame, making the device structure more compact and giving the lead screw a larger stroke range. The extension direction of the directional guide rail 5 is consistent with the axial direction of the lead screw. One side of the connecting block 6 is fixedly connected to the end of the lead screw, so that the axial movement of the lead screw can drive the connecting block to move. The connecting block is positioned near the transmission chamber and has a rope connection part 61 for subsequent fixing of the suspension rope. A mating part 62 is located at the upper end of the connecting block, engaging with the directional guide rail 5 to allow the connecting block to move linearly under the guidance of the directional guide rail and prevent rotation. The guide wheel assembly 7 includes a longitudinal guide wheel 71 and a transverse guide wheel 72, with the transverse guide wheel positioned above the longitudinal guide wheel and relatively close to the corresponding connecting block. Typically, the lead screw is equipped with a limiting component to restrict its travel range, and the transmission chamber has a corresponding mating component. When the limiting component moves in a certain direction to abut against the mating component, the subsequent movement of the lead screw in that direction is restricted, thereby controlling the raising and lowering range of the light array. A protective sleeve can be installed at the non-travel portion of the lead screw (i.e., the portion where the lead screw does not directly contact the transmission chamber during its movement).

[0029] The drive mechanism provides power to the lifting mechanism, causing the lead screw to move axially. The drive mechanism includes at least a drive motor 2, which is connected to a transmission chamber 41 and provides power to the turbine assembly within the transmission chamber, thereby causing the lead screw to move axially. Typically, for operational stability, the drive motor is indirectly connected to the transmission chamber via a transmission component 3. This transmission component includes at least one transmission rod connected to the transmission chamber. The transmission rod rotates under the action of the drive motor, causing the turbine assembly within the transmission chamber to operate. In a further embodiment, the transmission component 3 includes a steering gear 31, a first transmission rod 32, and a second transmission rod 33. The steering device has an input connector 311 and two output connectors 312 facing opposite directions. The input connector 311 is connected to the drive motor through the first transmission rod 32. Each output connector is connected to the housing 41 of a screw jack through a second transmission rod 33. When the first transmission rod rotates, the steering device can cause the two second transmission rods to rotate simultaneously, so that a single power source output by the drive motor can simultaneously control the operation of the two screw jacks. Preferably, the steering device can be set between two adjacent screw jacks on the short side of the support frame to enable the two screw jacks to operate synchronously, thereby improving the stability during the lifting process.

[0030] Reference Figure 4 Another embodiment of this utility model provides a sunlight simulation system, which includes Figures 1-3 The installation base, the light array 8 located below the installation base, and the suspension rope 9 connecting the light array and the installation base are shown. The middle part of the suspension rope cooperates with the guide wheel group 7. The first end of the suspension rope is fixedly connected to the light array 8 in the vertical direction, and the second end is fixedly connected to the rope connection part 61 of the connecting block 6 in the horizontal direction. When the lead screw drives the connecting block to move horizontally, the connecting block will pull the light array below through the suspension rope, so that the height of the light array rises or falls. In some embodiments, the screw jack located on the first short side of the support frame and the screw jack located on the second short side of the support frame can operate asynchronously, so that the two ends of the light array in the length direction are separated, thereby achieving the tilting setting of the light array.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
