Description

Technical Field

[0001] The present invention relates to the technical field of vehicle lamp detection, and in particular to a sealing and waterproof detection system for new energy vehicle lamps. Background Art

[0002] New energy vehicle headlights need to work continuously in a rainy environment without water ingress, and the fog needs to disappear quickly after no rain to ensure the lighting performance of the headlights. Under existing technology, the production of headlights requires the use of a headlight waterproof test chamber to test its lighting performance in a rainy environment.

[0003] The existing patent announcement number CN110793725A discloses a vehicle lamp waterproof testing device and a vehicle lamp waterproof testing method, which include a test box body and a spray pipe I, a spray pipe II, a rotating frame and a water circulation system inside it. The spray pipe I and the spray pipe II are rotatably connected to the test box body, and the rotating frame is arranged below the spray pipe I and the spray pipe II. The water circulation system includes a water tank, a water pump and a water supply pipe. The water tank is connected to the water supply pipe through the water pump, and the outlet of the water supply pipe is connected to the spray pipe I and the spray pipe II. A hollow structure is provided above the water tank.

[0004] In the above technical solution, by setting up rotatable spray pipes I and II, the headlights placed on the rotating frame can be sprayed in all directions for detection, thereby simulating whether rain from various angles affects the airtightness of the headlights. However, since the spray pipes are arranged in an arc shape and several nozzles are arranged in sequence, this causes the water flows sprayed from the several nozzles to intersect and collide, and it is impossible to truly simulate the rain during landing, thereby affecting the normal spraying of the headlights, resulting in inaccurate test results. In addition, the continuous arrangement of several nozzles further increases the cost.

Of course, they are merely examples and are not intended to limit the present application.

[0040] See also Figure 1-9 The present invention provides a technical solution: a closed waterproof detection system for new energy vehicle lights, comprising a detection chamber 6, an adjustment chamber 601, a carrier plate 5 and a spraying part.

[0041] A limit seat 501 is provided on the upper side of the carrier plate 5. The limit seat 501 is used to engage and limit the position of the lamp body. A plurality of spring members 502 are provided on the outer side of the carrier plate 5. A center plate 503 is provided on the outer side of the spring members 502. The center plate 503 is fixed between the detection chamber 6 and the adjustment chamber 601. The plurality of spring members 502 are used to limit the carrier plate 5 to maintain a horizontal position in the initial state.

[0042] The spraying part is arranged on the upper side of the interior of the detection chamber 6 and is used to spray the lamp body on the carrier plate 5;

[0043] The lower end of the supporting plate 5 is fixedly connected to several groups of upper fixing seats 1, and the several upper fixing seats 1 are evenly distributed in a ring shape with the supporting plate 5 as the axis. The lower inner end of the adjusting chamber 601 is provided with a bottom plate 101, and the upper end of the bottom plate 101 is similarly provided with several groups of lower fixing seats 102. A pull rope 103 is provided between each group of upper fixing seats 1 and the lower fixing seat 102, and an offset mechanism is provided on the middle side of the pull rope 103. The offset mechanism concentrates and limits the middle side parts of several groups of pull ropes 103. The pull rope 103 is bow-shaped as a whole. The offset mechanism is used to offset the middle side position of several pull ropes 103, so that the pull rope 103 pulls the supporting plate 5 accordingly to drive the car light body to tilt.

[0044] The vehicle lamp body is supported by setting a supporting plate 5. The staff first places the vehicle lamp body on the limiting seat 501, and limits and fixes it through the limiting seat 501 that is adapted to the shape of the vehicle lamp body. Then, the vehicle lamp body is subjected to a spray simulation test through the spray part. Preferably, the accumulated water at the bottom of the regulating chamber 601 is pumped out through the water pump assembly and sent to the spray head on the upper side of the detection chamber 6, so as to realize the circulating spray simulation. When the angle needs to be tilted, the supporting plate 5 is adjusted in angle through the regulating chamber 601. Specifically, on the lower side of the supporting plate 5, a plurality of upper fixing seats 1 are arranged in a ring, and on the bottom plate 101, a plurality of lower fixing seats 102 are similarly arranged. A pull rope 103 is connected between each group of upper and lower fixing seats, and an offset mechanism is provided at the middle side position of the plurality of pull ropes 103 to gather the plurality of pull ropes 103 in the center and perform tensioning and limiting. So that the pull rope 103 is in a bow shape as a whole (such as Figure 2 As shown in FIG), since a plurality of spring members 502 are provided on the outside of the carrier plate 5 and connected to the center plate 503, the initial state of the carrier plate 5 is kept in a horizontal position (as shown in FIG). Figure 2As shown), at this time, the plurality of pull ropes 103 also maintain the same bow-shaped state, that is, the entire support plate 5 is uniformly stressed. When the support plate 5 needs to be driven to adjust the angle of the headlight body, the middle positions of the plurality of pull ropes 103 are horizontally offset as a whole through the offset mechanism (the offset force is greater than the elastic force of the plurality of spring members 502). Since the lower end position of the pull rope 103 is fixed, when the middle side of the tensioned pull rope 103 is offset, the pull rope 103 pulls the upper support plate 5 to tilt in the opposite direction of the offset. The bending angle of the pull rope 103 close to the offset direction gradually increases, thereby releasing the length used for tilting, and the bending angle of the pull rope 103 in the opposite direction gradually decreases, thereby retracting the length used for tilting. In other words, When the angle is tilted, the pull ropes 103 on both sides are retracted and released, so that the lower side of the supporting plate 5 is unevenly stressed, and when it tilts to one side, the headlight body can be driven to adjust the angle to simulate the impact of precipitation on the headlight body at an inclined angle, and to detect whether its waterproof and airtightness is qualified. When the offset mechanism offsets several pull ropes 103, it can be offset in any direction along the outside of the several pull ropes 103, that is, it can be offset within 360 degrees, and the headlight body can be simulated for rainfall under most wind directions. The detection range is relatively comprehensive, and the design of several pull ropes 103 has a simple structure and saves costs. It can be preferably made of artificial fiber ropes such as nylon ropes, polyester ropes, etc. with strong wear resistance, high tensile strength, water resistance and corrosion resistance.

[0045] The offset mechanism includes a centering ring 104, and several triangular spacers 105 are arranged on the inner side of the centering ring 104. A limiting groove wheel 106 is arranged between the triangular spacers 105. The pull rope 103 is inserted into the inner side of the limiting groove wheel 106. The limiting groove wheel 106 limits the middle side of the pull rope 103 and tensions it. An eccentric mechanism is arranged on the outer side of the centering ring 104, and the eccentric mechanism is used to drive the centering ring 104 to shift horizontally.

[0046] Specifically, the surface of the limiting groove wheel 106 is an arc-shaped groove, and several pull ropes 103 are respectively stuck in the limiting groove wheels 106. By setting an eccentric mechanism on the outer side of the focusing ring 104, the focusing ring 104 is pushed to deflect horizontally, which can drive the limiting groove wheels 106 and the limited pull ropes 103 to deflect horizontally. The limiting groove wheel 106 rolls accordingly, thereby adapting to the relative movement of the several pull ropes 103, reducing friction and having strong adaptability. Moreover, since the pull ropes 103 are all tensioned, the pull ropes 103 are tightly attached to the grooves. When deflecting, the several pull ropes 103 can still be kept in the grooves for limiting, and several limiting groove wheels 106 are arranged adjacent to each other (such as Figure 3 As shown), the spacing between several adjacent pull ropes 103 is small, and they can be further limited to each other, thereby improving the stability of the carrying plate 5 when offset.

[0047] The upper end of the base plate 101 is fixedly connected to a support column 107, and the upper end of the support column 107 is fixedly connected to a number of triangular spacer blocks 108. The triangular spacer blocks 108 are arranged similarly to the triangular spacer blocks 105. A limiting groove wheel 106 is similarly arranged between the triangular spacer blocks 108, and the pull rope 103 is straightened and tensioned by the upper and lower layers of the limiting groove wheels 106.

[0048] Specifically, a support column 107, a triangular spacer block 108 and a limiting groove wheel 106 are provided on the bottom plate 101, and are correspondingly arranged on the lower side of the centering ring 104. Since the positions of the several limiting groove wheels 106 on the lower side are fixed, the stability of the tensioning of the pull rope 103 can be further improved, and the pressure on the limiting groove wheel 106 of the centering ring 104 can be reduced.

[0049] The eccentric mechanism includes a cam 2, the wheel surface of the cam 2 is in contact with the wheel surface of the centering ring 104. When the supporting plate 5 is in the initial state, the raised part of the cam 2 does not contact the centering ring 104. When the cam 2 rotates, the raised part pushes the centering ring 104 to one side.

[0050] Specifically, when it is necessary to drive the centering ring 104 to shift horizontally, a cam 2 is provided to fit in contact with the outer side of the cam 2. When the cam 2 rotates, the raised portion gradually pushes the centering ring 104 to shift it to one side. When the raised portion is no longer in contact with the centering ring 104, the centering ring 104 returns to its original position under the resetting action of the spring member 502, and the supporting plate 5 and the lamp body also return to a horizontal position.

[0051] The upper end of the support column 107 is fixedly connected to the support cover 201 , and the upper end of the support cover 201 is rotatably connected to the rotating inner ring 202 , and the upper side of the rotating inner ring 202 is rotatably connected to the cam 2 .

[0052] Specifically, the cam 2 is set on the rotating inner ring 202, so that the rotating inner ring 202 can drive the cam 2 to move in a circular manner, so that the cam 2 can push the centering ring 104 on any side of its outer side to offset it. The centering ring 104 and several limiting groove wheels 106, under the limiting action of the tensioned pull rope 103, will not rotate with the rotating inner ring 202 and the cam 2 under the action of friction, thereby realizing 360-degree tilt adjustment of the headlight body, and a wide adjustment range.

[0053] The upper end of the rotating inner ring 202 is fixedly connected to a plurality of groups of limit blocks 203. The plurality of limit blocks 203 are arranged on the other side of the cam 2. The inner side of the limit blocks 203 is provided with a clamping groove. The outer side of the middle side of the centering ring 104 is rotatably connected to a rotating clamping ring 204. The rotating clamping ring 204 is clamped into the clamping groove and has a clearance fit therewith. The clamping groove limits the horizontal movement of the centering ring 104.

[0054] An accommodating opening 205 for accommodating a rotating snap ring 204 is provided on the inner side of the middle side of the cam 2 .

[0055] like Figure 4 As shown, a plurality of limit blocks 203 are provided at the upper end of the rotating inner ring 202, and a rotating snap ring 204 is provided on the outer side of the middle side of the centering ring 104. The rotating snap ring 204 is restricted in a plurality of slots, thereby ensuring that the axis of the rotating snap ring 204 and the centering ring 104 remains vertical, that is, the centering ring 104 is restricted to horizontal movement only, and itself will not tilt or move up and down, thereby improving the stability when adjusting the angle of the carrier plate 5, and an accommodating port 205 is opened in the cam 2, so that the rotating snap ring 204 is always stuck in the accommodating port 205, further limiting its horizontal position, and will not hinder the normal rotation of the cam 2.

[0056] The outer side of the rotating inner ring 202 is rotatably connected to a rotating gear ring 206. A sliding groove 207 is provided at one end of the rotating gear ring 206. An eccentric rod 208 is slidably engaged with the inner side of the sliding groove 207. The lower end of the cam 2 is fixedly connected to a rotating rod 302. The lower end of the rotating rod 302 is rotatably connected to the rotating inner ring 202. The rotating rod 302 passes through and is fixedly connected to gear 1 3. One side of gear 1 3 is meshedly connected to gear 2 301. The lower end of gear 2 301 is rotatably connected to the rotating inner ring 202. The eccentric rod 208 is eccentrically arranged at one end of the lower side of gear 2 301.

[0057] The outer side of the rotating gear ring 206 is meshedly connected with a gear three 303 , and the gear three 303 is driven to rotate by the motor assembly.

[0058] When it is necessary to drive the cam 2 to rotate, the motor assembly drives gear three 303 to rotate, and gear three 303 drives the rotating gear ring 206 to rotate. The rotating gear ring 206 passes through the slide groove 207 and first pushes the eccentric rod 208 to move. The eccentric rod 208 moves in a ring with the rotating gear ring 206 as the axis. Since the center of the circle of gear two 301 is on the rotating inner ring 202 and the eccentric rod 208 is eccentrically arranged at the lower end of gear two 301, when the rotating gear ring 206 drives the eccentric rod 208 to move through the slide groove 207, the eccentric rod 208 drives gear two 301 to rotate relatively, and gear two 301 rotates and engages with gear one 3, thereby driving gear one 3 to rotate. Gear one 3 can drive the cam 2 to rotate through the rotating rod 302, so that the raised part of the cam 2 pushes the centering ring 104 to offset, thereby completing the tilt adjustment of the headlight body.

[0059] There is friction between the support cover 201 and the rotating inner ring 202. A fan-shaped groove 304 is provided on the upper side of the rotating inner ring 202. A clamping plate 305 is slidably fitted on the inner side of the fan-shaped groove 304. One end of the clamping plate 305 is fixedly connected to the rotating rod 302. A torsion spring is provided between the rotating rod 302 and the rotating inner ring 202.

[0060] Specifically, in this embodiment, the angle of the fan-shaped groove 304 is preferably 90 degrees, so that the fan-shaped groove 304 limits the rotation angle of the clamping plate 305, the rotating rod 302 and the cam 2, that is, the cam 2 can rotate at most 90 degrees, and a torsion spring is provided between the rotating rod 302 and the rotating inner ring 202, so that the cam 2 is in the initial state (such as Figure 4 As shown), the centering ring 104 can be pushed to the maximum offset distance by simply rotating it 90 degrees;

[0061] And a friction force is set between the support cover 201 and the rotating inner ring 202, which makes it possible that when the rotating gear ring 206 rotates (such as Figure 4 As shown in the figure, due to the existence of friction, the rotating inner ring 202 will not rotate easily, and the rotating gear ring 206 will drive the eccentric rod 208 and gear 2 301 to rotate relative to each other, thereby driving the cam 2 to rotate. After the cam 2 rotates 90 degrees, the clamping plate 305 contacts the other inner wall of the fan-shaped groove 304, making the cam 2 unable to rotate anymore. If the rotating gear ring 206 continues to rotate at this time, if the driving force is greater than the above-mentioned friction force, it will drive the rotating inner ring 202 to rotate together, thereby achieving the effect that the cam 2 always presses the outer side of the focusing ring 104 with the highest point of the raised part and moves along its circular shape, which makes the headlight body first adjusted to a tilted state, and then tilts in a circular shape in 360 degrees with the focusing ring 104 as the axis, automatically completing all-round analog adjustment, greatly improving detection efficiency, and can be achieved by only using a single motor component, saving cost.

[0062] A dividing block 4 is provided in the center of the centering ring 104, and a groove for accommodating the pull rope 103 is opened on the outer side of the dividing block 4, and the groove corresponds to the limiting groove wheel 106. The upper end face of the triangular spacer 105 extends to the upper side of the centering ring 104, and the upper end of the dividing block 4 is fixedly connected to the connecting block 401. A plurality of connecting plates are fixedly connected to the outer side of the upper end of the connecting block 401 in a ring shape. The vertical length of the connecting plate is equal to the extension length of the triangular spacer 105. The connecting plate is fixedly connected to the triangular spacer 105, and the upper ends of the connecting block 401 and the triangular spacer 105 are fixedly connected to the fixing plate 402.

[0063] In order to further improve the stability of the pull rope 103 when it is offset, this embodiment is provided with a dividing block 4 to further limit the positions of several pull ropes 103. Specifically, the dividing block 4 is set at the center of the centering ring 104 and is provided with a groove, which cooperates with the limiting groove wheel 106 to limit the pull rope 103.
