Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a cup holder roller curtain testing device for new energy vehicles. Background Art

[0002] With the continuous development of the automotive industry, the number of interior components in cars continues to increase. This includes automotive roller shutter storage boxes. Existing automotive air vents are mostly open cup holder storage boxes or flip-top cup holder storage boxes. The flip-top cup holder storage box closes via a flip-top structure. Similar to roller shutter structures, most use a roller shutter frame with hard plastic to move within the guide groove. This hard plastic directly rubs against the guide groove and does not deform. The roller shutter has an extremely poor feel when operating, and in serious cases, it can even affect safe driving. If adjustments are made to achieve a smoother operation during post-production, precise machining and high process requirements are required. Any slight irregularity is difficult to adjust, severely affecting production efficiency and cost control, and is not conducive to large-scale promotion.

[0003] Currently, after the manufacture of the cup holder roller blinds is completed, they need to be manually inserted one by one into the corresponding guide rail frame and manually pushed and pulled back and forth several times. During this process, the sliding friction resistance between the cup holder roller blinds and the guide rail groove is manually sensed to judge the quality of the cup holder roller blinds. This seriously restricts the testing efficiency and test results of the cup holder roller blinds. Summary of the Invention

[0004] The object of the present invention is to provide a new energy vehicle cup holder roller shutter testing device to solve the above-mentioned defects caused by the prior art.

[0007] The force measuring mechanism is arranged between the two limit mechanisms, and the force measuring mechanism can realize real-time detection of the sliding resistance during the cup holder roller blind test.

[0008] Preferably, the limit mechanism includes a horizontally installed plate, a vertically installed plate, a guide rail strip, a limit plate, a first hydraulic cylinder, a second hydraulic cylinder and a limit strip. The horizontally installed plate is arranged horizontally. The vertically installed plate is arranged front and back and is vertically fixed to the upper side of the horizontally installed plate. The guide rail strip is of a J-shaped structure and is horizontally installed on the upper side of the vertically installed plate. A guide rail groove is provided on the upper side of the guide rail strip. The limit plate is arranged parallel to the upper side of the horizontally installed plate. A first hinge seat is evenly distributed on the lower side of the limit plate. A second hinge seat is evenly distributed on the upper side of the horizontally installed plate. The first hinge seats and the second hinge seats correspond to each other one by one and are connected by a first hinge strip. The first hydraulic cylinder is arranged vertically upward and is installed in the middle of the horizontally installed plate. The end of the piston rod of the first hydraulic cylinder is threadedly connected with a sliding block. A sliding groove with an opening facing outward is provided in the middle section of the limit plate. The sliding block is of an I-shaped structure and is slidably connected to the sliding groove. A fixing plate is vertically connected to the limit plate beside the sliding groove. The second hydraulic cylinder is arranged horizontally backward and is installed on the upper part of the fixing plate. The end of the piston rod of the second hydraulic cylinder is connected with a third hinge seat. A U-shaped third hinge strip is hinged on the third hinge seat. A fourth hinge seat is welded to the lower part of the fixing plate. A fourth hinge strip is hinged on the fourth hinge seat. The other end of the third hinge strip is hinged to the other end of the fourth hinge strip. A L-shaped transition frame is connected to the rear side of the third hinge strip. The limit strip is of an arc-shaped structure and is welded to the rear end of the transition frame.

[0009] Preferably, the force measuring mechanism includes a mounting plate, a third hydraulic cylinder, a hinge frame, a tension and compression sensor, a fourth hydraulic cylinder and a linkage bar. The mounting plate is vertically installed between two horizontally installed plates. The third hydraulic cylinder is arranged horizontally forward and is installed on the mounting plate. The hinge frame is of a U-shaped structure and is arranged in front of the mounting plate. A U-shaped connecting piece is screwed to the middle of the hinge frame. A connecting column is vertically welded to the rear side of the connecting piece. The tension and compression sensor is coaxially connected between the connecting column and the piston rod of the third hydraulic cylinder. A pair of symmetrically distributed linkage frames are provided inside the hinge frame. Hinge seats five are welded on the side inner wall of the hinge frame and are distributed up and down. The upper and lower ends of the linkage frames on the same side are correspondingly hinged to the two hinge seats five by a pair of fifth hinge strips. The fourth hydraulic cylinder is arranged vertically upward and is installed in the middle of the hinge frame. The linkage bar is horizontally connected to the end of the piston rod of the fourth hydraulic cylinder. Rectangular linkage grooves are symmetrically provided on the left and right sides of the linkage bar. The pins connected to the lower ends of the linkage frames slide correspondingly in the linkage grooves on the same side.

[0014] Compared with the prior art, the new energy vehicle cup holder roller shutter test device of the present invention has the following advantages:

[0015] 1. The limit mechanism features convenient positioning and quick limiting. Specifically, with the limit plate as the front reference, the cup holder roller blind to be tested is placed horizontally on the straight section of the two guide rails. At this time, the toggle plate on the cup holder roller blind is located between the clamping blocks on both sides. The piston rod of hydraulic cylinder one contracts and drives the sliding block downward until the limit plate is tightly pressed against the straight section of the guide rail. The piston rod of hydraulic cylinder two extends and drives hinge bar three to rotate backward 90 degrees around hinge bar four until the limit bar is tightly pressed against the arc section of the guide rail.

[0016] 2. The force measuring mechanism is easy to clamp and has accurate force measurement. Specifically, the piston rod of hydraulic cylinder 4 contracts and drives the linkage bar downward, thereby driving the linkage frames on both sides to approach each other and move downward until the two clamping blocks on both sides are correspondingly clamped to the two corners of the toggle plate. The piston rod of hydraulic cylinder 3 contracts and drives the articulated frame backward, thereby driving the cup holder roller blind to gradually slide from the straight section of the guide bar to the arc section. During this period, the friction resistance between the cup holder roller blind and the guide bar is measured by the pull pressure sensor. Then, the piston rod of hydraulic cylinder 3 extends and drives the articulated frame forward, thereby driving the cup holder roller blind to gradually slide from the arc section of the guide bar to the straight section. During this period, the friction resistance between the cup holder roller blind and the guide bar is measured by the pull pressure sensor.

[0017] 3. The entire testing device is easy to use, accurate, and quick to judge. Specifically, by comparing the relationship between the two friction resistance values ​​measured above and the set friction value, it is determined whether the cup roller blind has a process defect, and thus good and bad products are distinguished.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 9 As shown, a new energy vehicle cup holder roller shutter testing device includes a limit setting mechanism 10 and a force measuring mechanism 20, wherein:

[0032] The limit mechanism 10 is provided in a pair and is symmetrically distributed on the left and right sides. The limit mechanism 10 can realize the rapid positioning and clamping of the cup holder roller blind 30 before and after the test;

[0033] The force measuring mechanism 20 is disposed between the two limiting mechanisms 10, and the force measuring mechanism 20 can perform real-time detection of the sliding resistance during the test of the cup holder roller blind 30.

[0034] In this embodiment, the limiting mechanism 10 includes a horizontally installed plate 101, a vertically installed plate 102, a guide rail strip 103, a limiting plate 105, a first hydraulic cylinder 109, a second hydraulic cylinder 112, and a limiting strip 118. The horizontally installed plate 101 is arranged horizontally, the vertically installed plate 102 is arranged front and back and is vertically fixed to the upper side of the horizontally installed plate 101. The guide rail strip 103 has a J-shaped structure and is horizontally installed on the upper side of the vertically installed plate 102. A guide rail groove 103a is provided on the upper side of the guide rail strip 103. The limiting plate 105 is arranged parallel to the upper side of the horizontally installed plate 101. A first hinge seat 106 is evenly distributed on the lower side of the limiting plate 105. A second hinge seat 107 is evenly distributed on the upper side of the horizontally installed plate 101. The first hinge seat 106 and the second hinge seat 107 correspond to each other one by one and are connected by a first hinge bar 108. The first hydraulic cylinder 109 is arranged vertically upward and is installed in the middle of the horizontally installed plate 101. The end of the piston rod of the first hydraulic cylinder 109 is threadedly connected with a sliding block 110. A sliding groove 105a with an outward opening is provided in the middle section of the limiting plate 105. The sliding block 110 has an I-shaped structure and is slidably connected to the sliding groove 105a. A fixing plate 111 is vertically connected to the limiting plate 105 beside the sliding groove 105a. The second hydraulic cylinder 112 is arranged horizontally backward and is installed on the upper part of the fixing plate 111. The end of the piston rod of the second hydraulic cylinder 112 is connected with a third hinge seat 113. A U-shaped third hinge bar 114 is hinged on the third hinge seat 113. A fourth hinge seat 115 is welded to the lower part of the fixing plate 111. A fourth hinge bar 116 is hinged on the fourth hinge seat 115. The other end of the third hinge bar 114 is hinged to the other end of the fourth hinge bar 116. A L-shaped transition frame 117 is connected to the rear side of the third hinge bar 114. The limiting strip 118 has an arc-shaped structure and is welded to the rear end of the transition frame 117. By the contraction of the piston rod of the first hydraulic cylinder 109 and the downward movement of the sliding block 110, at the same time, the sliding block 110 presses the limiting plate 105 downward and inward until the limiting plate 105 tightly presses against the straight section part of the guide rail strip 103. By the extension of the piston rod of the second hydraulic cylinder 112 and the backward rotation of the third hinge bar 114 around the fourth hinge bar 116 by 90 degrees, at the same time, the third hinge bar 114 brings the limiting strip 118 forward to rotate 90 degrees until the limiting strip 118 tightly presses against the arc section part of the guide rail strip 103.

[0035] In this embodiment, the force measuring mechanism 20 includes a mounting plate 201, a third hydraulic cylinder 202, a hinge frame 203, a tension and compression sensor 206, a fourth hydraulic cylinder 210 and a linkage bar 211. The mounting plate 201 is vertically installed between two horizontally installed plates 101. The third hydraulic cylinder 202 is horizontally arranged forward and installed on the mounting plate 201. The hinge frame 203 is of a "U" - shaped structure and is arranged directly in front of the mounting plate 201. A "ㄇ" - shaped connecting piece 204 is screwed to the middle of the hinge frame 203. A connecting column 205 is vertically welded to the rear side of the connecting piece 204. The tension and compression sensor 206 is coaxially connected between the connecting column 205 and the piston rod of the third hydraulic cylinder 202. A pair of symmetrically distributed linkage frames 207 are arranged inside the hinge frame 203. On the inner side wall of the hinge frame 203, hinge seats five 208 are welded in an up - and - down distribution. The upper and lower ends of the linkage frame 207 on the same side are correspondingly hinged to the two hinge seats five 208 through a pair of hinge bars five 209. The fourth hydraulic cylinder 210 is vertically arranged upward and installed in the middle of the hinge frame 203. The linkage bar 211 is horizontally connected to the end of the piston rod of the fourth hydraulic cylinder 210. Rectangular linkage grooves 211a are symmetrically arranged on the left and right sides of the linkage bar 211. The pins connected to the lower end of the linkage frame 207 slide correspondingly in the linkage grooves 211a on the same side. A rear - extending overhanging bar 212 is welded to the upper part of the linkage frame 207. A clamping block 213 is connected to the overhanging end of the overhanging bar 212. A rectangular clamping groove 213a is provided on the clamping block 213.

[0036] In this embodiment, a rectangular mounting groove 102a is provided on the upper side of the vertically installed plate 102. The guide rail strip 103 is horizontally clamped in the mounting groove 102a, and its rear end is screwed to the rear side of the vertically installed plate 102. By designing the mounting groove 102a, precise assembly between the guide rail strip 103 and the vertically installed plate 102 can be achieved.

[0037] In this embodiment, a limiting piece 104 is installed at the front port of the guide rail groove 103a of the vertically installed plate 102. By adding the limiting piece 104, initial precise positioning of the cup - supporting rolling curtain 30 in the guide rail groove 103a of the guide rail strip 103 can be achieved.

[0038] In this embodiment, an avoidance groove 101a allowing the fourth hydraulic cylinder 210 to pass freely is provided between the two horizontally installed plates 101. By leaving the avoidance groove 101a, the fourth hydraulic cylinder 210 can move freely in the front - and - back direction.

[0039] In this embodiment, the clamping groove 213a can be in clearance fit with the拨动片40 on the cup - supporting rolling curtain 30. By adopting the clearance - fit method, it is convenient for the clamping block 213 to be smoothly clamped onto the拨动片40.

[0040] The practical application of this new energy vehicle cup holder roller shutter test device includes the following operating steps:

[0041] Step 1: Using the limiting piece 104 as the front reference, horizontally place the cup holder roller blind 30 to be tested on the straight sections of the two guide rails 103. At this time, the toggle piece 40 on the cup holder roller blind 30 is located between the two clamping blocks 213.

[0042] Step 2: The piston rod of the hydraulic cylinder 109 contracts and drives the sliding block 110 to move downward. At the same time, the sliding block 110 presses the limit plate 105 downward and inward until the limit plate 105 is tightly pressed against the straight section of the guide rail 103.

[0043] Step 3: The piston rod of the second hydraulic cylinder 112 extends and drives the third hinge bar 114 to rotate backward 90 degrees around the fourth hinge bar 116. At the same time, the third hinge bar 114 rotates the limiting bar 118 forward 90 degrees until the limiting bar 118 is tightly pressed against the arc section of the guide rail 103.

[0044] Step 4: The piston rod of the hydraulic cylinder 210 contracts and drives the linkage bar 211 to move downward, thereby driving the linkage frames 207 on both sides to move closer to each other and move downward. At the same time, the clamping blocks 213 on both sides will synchronously move closer to each other and move downward until the clamping blocks 213 on both sides are correspondingly clamped to the two corners of the toggle plate 40;

[0045] Step 5: The piston rod of the third hydraulic cylinder 202 contracts and drives the articulated frame 203 to move backward, thereby driving the cup holder roller blind 30 to gradually slide from the straight section of the guide rail 103 to the arc section. During this period, the friction resistance between the cup holder roller blind 30 and the guide rail 103 is measured by the tension pressure sensor 206, which is recorded as f1. Then, the piston rod of the third hydraulic cylinder 202 extends and drives the articulated frame 203 to move forward, thereby driving the cup holder roller blind 30 to gradually slide from the arc section of the guide rail 103 to the straight section. During this period, the friction resistance between the cup holder roller blind 30 and the guide rail 103 is measured by the tension pressure sensor 206, which is recorded as f2.

[0046] Step 6: The piston rod of the second hydraulic cylinder 112 contracts and drives the third hinge bar 114 to rotate forward 90 degrees around the fourth hinge bar 116. At the same time, the third hinge bar 114 rotates the limit bar 118 backward 90 degrees until the limit bar 118 returns to its original spatial posture.

[0047] Step 7: The piston rod of the hydraulic cylinder 109 extends and drives the sliding block 110 to move upward. At the same time, the sliding block 110 pushes the limit plate 105 upward and outward until the limit plate 105 returns to its initial spatial posture.

[0048] Step 8: By determining the relationship between f1 / f2 and the set friction value, it is determined whether the cup roller blind 30 has a process defect, and thereby distinguishing good products from defective products.

[0049] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
