Description

Technical Field

[0001] This utility model belongs to the field of automotive parts testing and adjustment, specifically relating to a damping retraction time adjustment fixture for sun visor roller blinds. Background Technology

[0002] In the automotive manufacturing industry, sun visor roller blinds are an important component of vehicle interiors. They not only effectively block sunlight and provide a comfortable riding environment for drivers and passengers, but also protect the interior trim from UV damage to a certain extent.

[0003] However, in the production and assembly of sunshade roller blinds, damping adjustment often becomes a major obstacle to production efficiency and product quality. Traditional damping adjustment methods often rely on the personal experience and feel of the operators. This not only means that each worker may use different standards and methods, increasing uncertainty and variability in the production process, but also often requires repeated manual adjustments to achieve a near-ideal damping effect. This manual approach is not only time-consuming and labor-intensive, but also increases production costs.

[0004] Specifically, traditional damping adjustment methods often lack quantitative standards and precise measurement means, leading to significant fluctuations in the retraction speed of roller blinds during actual use. Excessively fast or slow retraction not only affects the ease of use and user experience of the sunshade roller blind but may also exacerbate component wear due to frequent mechanical movement, shortening the product's lifespan. More importantly, this method, relying on repeated trial and error and manual adjustment, cannot guarantee the consistency and accuracy of each adjustment. This can result in significant differences in damping performance between different batches, and even within the same batch, severely impacting the overall product quality and market competitiveness.

[0005] Therefore, designing a fixture that can efficiently and accurately adjust the damping retraction time of the sun visor roller blind has become an urgent problem to be solved in the automotive manufacturing industry. Utility Model Content

[0006] The purpose of this invention is to provide a damping retraction time adjustment fixture that can simulate the actual operating state of a roller shutter, measure the retraction time of the roller shutter, improve adjustment efficiency, and reduce the number of manual operations and time.

[0007] The technical solution proposed by this utility model is as follows:

[0008] A damping contraction time adjustment fixture, the damping contraction time adjustment fixture comprising:

[0009] A positioning mechanism includes a positioning track for placing a roller blind, with sensors at both the front and rear ends of the positioning track for sensing the retraction of the roller blind; a pressure strip for pressing down the roller blind is provided above the positioning track, the pressure strip being located near the rear end of the positioning track; a damping end positioning block for positioning the damping end of the roller blind and a spring end positioning block for positioning the roller blind are also provided at the rear end of the positioning track, and the spring end positioning block is connected to a drive motor for driving the spring end positioning block; a force value detection positioning mechanism is provided below the positioning track.

[0010] A simulated operating mechanism is provided on one side of the positioning mechanism, and the simulated operating mechanism is parallel to the retraction direction of the roller shutter on the positioning mechanism;

[0011] A toggle mechanism is disposed above the positioning mechanism and is movably disposed on the simulated operation mechanism.

[0012] The positioning track has a U-shaped structure and includes two parallel track grooves for extending and retracting the roller blind.

[0013] The simulated running mechanism includes a slide rail parallel to the direction of the track groove, and a slider that can move along the slide rail is provided on the slide rail.

[0014] The actuating mechanism includes a vertically moving device connected to the slider. The bottom of the vertically moving device is provided with a lever for actuating the roller blind, and the bottom of the lever has a groove that engages with the roller blind. The actuating mechanism is used to actuate the sliding cover assembly on the roller blind, facilitating the pulling out of the roller blind and placing it on the positioning track. The vertically moving device drives the lever to descend, and the groove of the lever engages with the sliding cover assembly of the roller blind, moving the sliding cover assembly to pull out the roller blind.

[0015] The damping end positioning block and the spring end positioning block are respectively provided with a damping end positioning groove and a spring end positioning groove. These are used to place both ends of the inner tube spring assembly of the roller shutter in the damping end positioning groove and the spring end positioning groove, respectively, so as to position the inner tube spring assembly.

[0016] The pressure strip is mounted above one side of the positioning track via a fixing block, and the pressure strip is pivotally connected to the fixing block.

[0017] The force detection and positioning mechanism includes a force detector disposed below the positioning track and a force positioning block disposed below the force detector for positioning the force detector. A cylinder for moving the force positioning block is disposed below the force positioning block.

[0018] Preferably, the top of the force detector is provided with a protrusion for positioning the roller shutter.

[0019] The beneficial effects of this utility model are: through the coordinated action of the positioning mechanism, the simulation operation mechanism and the actuation mechanism, this utility model can simulate the actual operating state of the roller blind and measure the roller blind rewinding time. At the same time, by using the drive motor to drive the spring end positioning block to rotate, the spring end can be adjusted, which improves the adjustment efficiency and reduces the number of manual operations and time.

[0058] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0059] like Figure 1 and Figure 2As shown, this utility model provides a damping retraction time adjustment fixture, which includes a positioning mechanism 1, a simulation operation mechanism 2, and a toggle mechanism 3 mounted on a frame 15. The positioning mechanism 1 includes a parallel positioning track 5 for placing the roller blind 4, allowing the roller blind 4 to stretch and retract on the positioning track 5, facilitating the adjustment of the damping retraction time of the roller blind 4. Sensing devices 6 are provided at both the front and rear ends of the positioning track 5. The sensing devices 6 in this utility model are common industry structures, such as fiber optic sensors and timers, used to sense the time it takes for the front end of the roller blind 4 to pass through the front and rear ends of the positioning track 5 during retraction, and to calculate the time it takes for the front end of the roller blind 4 to pass through the front and rear ends of the positioning track 5. A pressure strip 7 is provided above the positioning track 5 to hold the roller blind 4 in place. After the roller blind 4 is placed on the positioning track 5, it can further position the roller blind 4 during retraction to prevent it from swaying and affecting the adjustment. A force value detection and positioning mechanism 13 is provided below the positioning track 5. The force value detection and positioning mechanism includes a force value detector 131 located below the front end of the positioning track 5 and a force value positioning block 132 located below the force value detector 131. The force value detector 131 can position the roller blind 4 when it is pushed to the front end of the positioning track 5 and measure the stretching force of the roller blind 4. A damping end positioning block 8 and a spring end positioning block 9 are provided at the rear end of the positioning track 5. The damping end positioning block 8 and the spring end positioning block 9 are respectively provided with a damping end positioning groove 81 and a spring end positioning groove, which are used to place the two ends (damping end 42 and spring end 43) of the inner tube spring assembly 41 of the roller blind 4 into the damping end positioning groove 81 and the spring end positioning groove 82, respectively, so as to position the inner tube spring assembly 41. The spring end positioning block 9 is connected to the drive motor 10. When the retraction time of the test roller blind 4 does not meet the set range, the drive motor 10 can be used to drive the spring end positioning block 9 to rotate, and the damping end positioning block 8 can drive the damping end 42 of the roller blind 4 to rotate half a turn to adjust the damping end 42. The retraction time of the roller blind 4 can be tested again until it meets the time standard.

[0060] Furthermore, the actuating mechanism 3 is positioned above the positioning mechanism 1, and is movably mounted on the simulated operating mechanism 2. The actuating mechanism 3 is used to actuate the sliding cover assembly 44 on the roller shutter 4, so as to pull out the curtain 43 of the roller shutter 4 and place it on the positioning track 5. The simulated operating mechanism 2 is positioned to one side of the positioning mechanism 5, and is used to move the actuating mechanism 3 along the direction of the simulated operating mechanism. The simulated operating mechanism 2 includes a slide rail 21 parallel to the direction of the positioning track 5, and a slider 22 movable along the slide rail 21 is provided on the slide rail 21.

[0061] The actuating mechanism 3 includes a vertical moving device 31 connected to the slider 22. The vertical moving device 31 is connected to a lever 32 for actuating the sliding cover assembly 44 of the roller blind 4. The bottom of the lever has a groove 33 that engages with the roller blind. The vertical moving device 31 of this invention can be a common structure in the industry, such as a cylinder. The appropriate choice can be made based on suitability, ensuring the functionality is achieved. In use, the vertical moving device 31 drives the lever 32 to descend. The groove of the lever 32 engages with the sliding cover assembly 44 of the roller blind 4, actuating the sliding cover assembly 44 to pull out the curtain 45.

[0062] The positioning track 5 has a U-shaped structure and includes two parallel track grooves 51 to facilitate the movement test of the roller blind 4 within the track grooves.

[0063] The pressure strip 7 is set above one side of the positioning track 5 via the fixing block 11, and the pressure strip 7 is pivotally connected to the fixing block 11. After the curtain 45 is placed on the positioning mechanism, the pressure strip 7 is flipped to press the curtain 45 into place. After the test is completed, the pressure strip 7 can be flipped to remove the curtain 45.

[0064] The force detection and positioning mechanism 13 is mounted on the frame 15. It includes a force detector 131 positioned below the positioning track and a force positioning block 132 positioned below the force detector 131 for positioning the force detector 131. A cylinder 133 for moving the force positioning block is located below the force positioning block 132. The cylinder 133 is fixed to the frame 15 by a bracket (not shown). In use, the cylinder 133 drives the force positioning block 132 to move the force detector 131 up and down. The top of the force detector 131 is provided with a protrusion 1311 for positioning the sliding cover assembly 44 of the roller shutter 4. The protrusion 1311 can lock the sliding cover assembly 44, position the sliding cover assembly 44, and measure the force of the roller shutter's retraction. After measurement, the cylinder 133 drives the force positioning block 132 to lower the force detector 131 and disengage it from the sliding cover assembly 44, causing the roller shutter to retract. The force sensor 131 of this invention is a common existing structure in the field. The pressure element on the protrusion 1311 can measure the rewinding force of the roller shutter when positioning the sliding cover assembly 44.

[0065] A safety light curtain 14 is also installed on the frame 13 to ensure the safety of the operator. This utility model can also be electrically connected to the electrical control box and the operation panel, which can further realize the automatic adjustment of the roller shutter 4, saving manpower and time.

[0066] In use, this invention first removes the pin 46 from the roller blind 4, then positions the damping end 42 and spring end 43 of the roller blind 4 in the damping end positioning groove 81 and spring end positioning groove, respectively. After the pressure strip 7 is flipped to press down the curtain 45, the actuating mechanism 3 moves the sliding cover assembly 44 to the front end of the positioning track 5. The sensing device 6 senses the signal received by the sliding cover assembly 44 and issues a command. The cylinder 133 drives the force value detector 131 to rise and position the sliding cover assembly 44, measuring the roller blind's rewinding force. Then, the force value detector 131 releases its position on the sliding cover assembly 44, causing the roller blind 4 to retract and rewind along the track groove 51. The sensing device 6 senses the time it takes for the front end of the roller blind 4 to pass through the front and rear ends of the positioning track 5 during retraction and calculates the time it takes for the front end of the roller blind 4 to pass through the front and rear ends of the positioning track 5, determining whether the rewinding time is within the set requirements. If the winding time exceeds the lower limit of the set range, the drive motor 10 drives the spring end positioning block 9 to rotate and lower the spring end 43 by half a turn. The lever 31 moves along the slide rail 21 to the position of the sliding cover group 44. The vertical moving device lowers and moves the sliding cover group 44 to pull out the curtain 45, and then releases the roller blind 4 to retract. The winding time of the roller blind 4 is measured until the time is within the acceptable range. If the winding time exceeds the upper limit of the set range, the drive motor 10 drives the spring end positioning block 9 to rotate the spring end 43 by half a turn. The lever 31 moves along the slide rail 21 to the position of the sliding cover group 44. The vertical moving device lowers and moves the sliding cover group 44 to pull out the curtain 45, and then releases the roller blind 4 to retract. The winding time of the roller blind 4 is measured until the time is within the acceptable range. After the final adjustment, insert the pin 46 into the positioning hole of the spring end 42, flip open the pressure strip 7, and remove the roller blind 4.

[0067] The structure of this utility model can be electrically connected to electrical control boxes, touch screens, etc., and its electrical principle is a common principle in this field.
