Description

Technical Field

[0001] This utility model relates to the field of sunshade curtain drape detection technology, and in particular to a sunshade curtain drape detection mechanism. Background Technology

[0002] Car sunshades are used to block sunlight from reaching the front, rear, and side windows of a car, as well as the sunroof. They are made of PVC. In summer, when driving, car sunshades are fixed to the car windows using suction cups to effectively block sunlight and also have a heat dissipation function.

[0003] According to a Chinese patent document (authorization announcement number: CN216558793U), a sunshade drape testing mechanism includes an inspection table. The bottom of the inspection table has a column and a control console. The top of the inspection table has an electromagnetic slide rail, and the top of the electromagnetic slide rail is connected to an electromagnetic slider. The top of the electromagnetic slider has a displacement plate, and the top of the displacement plate has an adjusting block. The bottom of the adjusting block has a ball bearing, and a bidirectional lead screw is connected to the adjusting block. Vertical plates are connected to both ends of the bidirectional lead screw, and a drive motor is located on the outer side of the vertical plate. This invention, by setting up an adjusting block, ball bearing, bidirectional lead screw, vertical plate, and drive motor, allows the drive motor on the vertical plate to rotate the bidirectional lead screw before operation, based on the width of the sunshade. This causes the adjusting block to move via the ball bearing, changing the distance between the two fixing mechanisms on one displacement plate. This greatly improves the applicability of the device to sunshades of different sizes and facilitates the fixing of the four corners of the sunshade.

[0004] However, the above plan still has some shortcomings in its implementation:

[0005] This device has made significant improvements to the fixing of sunshades, but it lacks an effective adjustment mechanism for the sensor, making it difficult to flexibly adjust the measurement position. Car sunshades are not completely flat planes. After being installed on a car, their sag varies in different parts due to various factors. Since the sensor cannot be adjusted, it cannot perform comprehensive and accurate sag detection on all planes of the sunshade, resulting in significant limitations in the detection results. It cannot fully reflect the actual sag state of the sunshade, thus affecting the accurate assessment of product quality.

[0006] Therefore, we propose a shading curtain drape testing mechanism. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of effective adjustment mechanisms in sensors, making it difficult to flexibly adjust the measurement position. When faced with sunshades with complex shapes and varying drapes, it is impossible to comprehensively and accurately detect all planar positions, resulting in limited detection results and affecting product quality assessment.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A sunshade curtain droop detection mechanism includes an operating table, with adjustment components on both side walls of the operating table, and a soft connection sensor assembly installed between two of the adjustment components, wherein the two adjustment components can drive the soft connection sensor assembly to move.

[0010] The adjustment assembly includes two drive wheels, a belt is fitted between the two drive wheels, a drive connecting block is also installed on the belt, and a sliding block is provided on the top of the drive connecting block.

[0011] As a preferred embodiment of this utility model, the adjustment component further includes a mounting base, the mounting base having an internal mounting cavity, two support seats being installed at each end of the internal mounting cavity, and anti-collision blocks being connected to the inner sides of the four support seats.

[0012] As a preferred embodiment of this utility model, a linear guide rail is installed between each of the two adjacent anti-collision blocks, and a drive motor is provided at the connection point of each of the drive wheels.

[0013] In a preferred embodiment of this utility model, the drive motor drives the drive wheel to rotate, and the drive wheel is connected to the two support seats. When the drive wheel rotates, it drives the belt to move.

[0014] As a preferred embodiment of this utility model, the drive connecting block is fixedly connected to the belt, and the drive connecting block is fixedly connected to the sliding block. Thus, when the belt is displaced, it will drive the drive connecting block and the sliding block to be displaced. The bottom of the sliding block is also slidably connected to the two linear guide rails.

[0015] As a preferred embodiment of this utility model, the soft connection sensor assembly includes a movable base, the movable base having a plurality of mounting holes inside, each of the plurality of mounting holes having a rubber sleeve inside, and each of the plurality of rubber sleeves having a laser sensor inside.

[0016] In a preferred embodiment of this invention, the movable seat and the sliding block are fixedly connected.

[0017] As a preferred embodiment of this utility model, a fixing structure is installed at the four corners of the top of the operating table, and a support leg is fixedly installed at the four corners of the bottom of the operating table.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In this invention, the design of the adjustment component utilizes a drive motor to rotate the drive wheel, which in turn moves the belt, causing the drive connecting block and sliding block to shift accordingly. Ultimately, this shifts the soft-connection sensor assembly, which is fixedly connected to the sliding block, allowing for flexible adjustment of the sensor's measurement position. This enables comprehensive detection of different planar positions of the car sunshade, overcoming the limitation of the detection range in existing technologies. The detection results can more completely reflect the actual drooping state of the sunshade, improving the accuracy of product quality assessment.

[0020] Furthermore, the flexible connection sensor assembly uses a rubber sleeve installed in the mounting hole inside the moving base, and then the laser sensor is placed inside the rubber sleeve. The rubber sleeve has a flexible buffering effect and is a flexible connection, which can effectively reduce the impact of external vibration on the sensor and improve the sensor measurement stability. Compared with the traditional rigid installation method, it can significantly reduce measurement error and improve the sag detection accuracy.

[0021] Finally, a drive wheel and belt drive system is adopted. Belt drive is relatively smooth and reduces mechanical impact during start-up, stopping and reversing compared to the sliding friction and backlash problems of the lead screw and nut pair. At the same time, the drive wheel is connected to the support base, and anti-collision blocks are set in the support base. Linear guide rails are installed between adjacent anti-collision blocks, and the bottom of the sliding block is slidably connected to the linear guide rail. These structural designs further ensure the stability of the driving process, reduce the vibration transmitted to the sensor, and provide a stable driving foundation for accurate detection.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0031] like Figure 1-4 As shown, this utility model provides a technical solution: In traditional car sunshade sag detection equipment, the position of the sensor is often fixed, which means that only specific positions of the sunshade can be detected, and it is impossible to fully reflect the sag of different parts of the sunshade. However, this utility model successfully overcomes this problem by designing an adjustment component.

[0032] The adjustment assembly mainly consists of two drive wheels 24, a belt 26, a drive connecting block 210, a sliding block 29, a mounting base 21, a mounting cavity 22, a support base 23, a collision protection block 27, and a linear guide rail 28. The mounting cavity 22 inside the mounting base 21 provides installation space for each component. The two support bases 23 are respectively installed at both ends inside the mounting cavity 22. They support the drive wheels 24 and ensure that the drive wheels 24 can rotate stably. The connection between the drive wheels 24 and the support bases 23 ensures the stability of the drive wheels 24 during rotation.

[0033] In the adjustment assembly, the drive motor 25 is the power source. When the drive motor 25 starts, it drives the drive wheel 24 connected to it to rotate. Since a belt 26 is sleeved between the two drive wheels 24, according to the transmission principle of the belt 26, the rotation of one drive wheel 24 will drive the belt 26 to move, which in turn drives the other drive wheel 24 to rotate synchronously. The drive connecting block 210 is fixedly connected to the belt 26, so when the belt 26 moves, the drive connecting block 210 will also move accordingly. Since the drive connecting block 210 is fixedly connected to the sliding block 29, the sliding block 29 will also move along with it. The bottom of the sliding block 29 is slidably connected to the linear guide rail 28. The linear guide rail 28 provides guidance for the movement of the sliding block 29, ensuring the straightness and stability of its movement.

[0034] In the process of sag detection, the stability of the sensor is crucial. Traditional rigid-mounted sensors are easily affected by external vibrations, resulting in large measurement errors. The flexible connection sensor assembly of this invention solves this problem well.

[0035] The flexible connection sensor assembly includes a movable base 31, mounting holes 32, a rubber sleeve 33, and a laser sensor 34. The movable base 31 has several mounting holes 32 inside, which are used to install the rubber sleeve 33 and the laser sensor 34. The rubber sleeve 33 has flexible buffering properties, which wraps the laser sensor 34 inside to form a flexible connection structure. When external vibration occurs, the rubber sleeve 33 can absorb and buffer the vibration energy, reduce the direct impact of vibration on the laser sensor 34, and thus ensure that the laser sensor 34 can perform stable measurements.

[0036] The movable seat 31 is fixedly connected to the sliding block 29. When the sliding block 29 is displaced under the drive of the adjustment component, the movable seat 31 will also move along with it, thereby driving the laser sensor 34 installed on it to move to different positions to detect the sag of the car sunshade at different plane positions.

[0037] Overall Workflow Summary

[0038] The workflow of this automotive sunshade sag testing fixture is an organic whole, with each part working together to achieve efficient and accurate sag testing.

[0039] First, the operator places the car sunshade on the fixed structure 4 of the operating table 1 to ensure that the sunshade is fixed in position. Then, the operator starts the drive motor 25 in the adjustment assembly. The drive motor 25 drives the drive wheel 24 to rotate, which is transmitted through the belt 26 to move the drive connecting block 210 and the sliding block 29, thereby moving the soft connection sensor assembly to the position to be detected. During the movement, the linear guide rail 28 ensures the stability of the movement of the sliding block 29, and the support base 23 and the anti-collision block 27 further reduce the generation of vibration.

[0040] Once the flexible connection sensor assembly is moved to the designated position, the laser sensor 34, under the buffer protection of the rubber sleeve 33, stably detects the sag of the car sunshade. Since the flexible connection sensor assembly can be flexibly adjusted, it can comprehensively detect different planar positions of the sunshade, and the detection results more accurately reflect the actual sag status of the sunshade.

[0041] In summary, this invention achieves flexible adjustment of the sensor position through the adjustment component, and improves the stability and accuracy of the measurement through the soft connection of the sensor component. Compared with the prior art, it has significant advantages in detecting the droop of automotive sunshades.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
