Description
Technical Field
[0001] This invention belongs to the field of testing device technology, specifically relating to a vehicle recorder testing device. Background Technology
[0002] A dashcam is a device that records video and audio information while a vehicle is in motion. After installation, it records the entire driving process, providing evidence in case of traffic accidents. For those who enjoy road trips, it can also be used to record the process of overcoming challenging terrains. It records video while driving, simultaneously capturing the time, speed, and location.
[0003] Before leaving the factory, dashcams need to undergo testing and verification. For example, to verify their performance and stability on bumpy roads or in the event of a vehicle collision, a crash test is required. In existing technologies, the dashcam is usually placed on a test vehicle, which is then placed on a crash test device, and a crash is simulated according to the test plan. This test may require the test vehicle to hit an obstacle at a certain speed. However, this test method is usually instantaneous and a single event, while a real collision is a dynamic process that may involve multiple consecutive or superimposed impacts. Therefore, existing testing devices are difficult to accurately simulate multi-directional coupled impacts and cannot simulate the continuous dynamics of the collision process.
[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Summary of the Invention
[0005] The purpose of this invention is to provide a dashcam testing device that can simulate the continuous dynamics during a collision, making the test results more accurate.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:
[0007] A dashcam testing device includes a movable mechanism for mounting a dashcam, a test box housing the movable mechanism, and traction mechanisms located on both sides of the test box that move the movable mechanism within the test box. The movable mechanism includes a lower movable base, an upper placement platform, and multiple sets of telescopic rods connected between the movable base and the placement platform, the sets of telescopic rods being rectangularly distributed. The upper end of each telescopic rod set has a first connecting ball joint connected to the bottom of the placement platform, and the lower end has a second connecting ball joint connected to the top of the movable base. The placement platform has rotatably mounted collision guide wheels at its four corners, and a support rod is mounted at the bottom of the placement platform, with a vibration guide wheel at the bottom of the support rod. The movable base includes a frame and movable rollers located at the bottom of the frame; the vibration guide wheels can pass through the frame. The test chamber has a guide rail on its inner bottom wall, and the movable roller is movably engaged within the guide rail. The test chamber has a bump test section in the middle and collision test sections at both ends of the bump test section. A test platform is formed on the inner bottom wall of the test chamber, and first guide ramps are formed at both ends of the test platform. Several first protrusions are provided on the test platform, and the distance between adjacent first protrusions is greater than the diameter of the vibrating guide wheel. The collision guide wheel makes rolling contact with the inner walls on both sides of the bump test section. Several second protrusions are formed on the two inner side walls of the collision test section, and the second protrusions on the two inner side walls are staggered. The distance between adjacent second protrusions is greater than the diameter of the collision guide wheel. The width of the collision test section is greater than the width of the bump test section. A second guide ramp is formed between the collision test section and the bump test section.
[0008] Furthermore, both the circumferential surfaces of the collision guide wheel and the vibration guide wheel are covered with rubber pads.
[0009] Furthermore, the placement platform is provided with multiple sets of mounting strips, each mounting strip having multiple mounting bases for mounting the dashcam, and each mounting base having clamps for securing the dashcam; the mounting strips are movably connected to the placement platform. This plug-in connection facilitates quick installation of the mounting strips onto the placement platform.
[0010] Furthermore, a mounting groove is formed on the placement platform, and a fixing component is provided at the inlet end of the mounting groove. The fixing component includes a plug-in block movably mounted on the placement platform and a compression spring. A receiving cavity is formed on the placement platform for the plug-in block to slide. The compression spring is fixedly connected to the bottom of the plug-in block, and a plug-in groove that mates with the plug-in block is formed at the bottom of the mounting strip. The cooperation between the plug-in block and the compression spring facilitates quick and easy fixing of the mounting strip.
[0011] Furthermore, a lever is formed on one side of the plug-in block, and a through groove is formed on the outer side of the placement platform for the lever to pass through; a pulley is rotatably mounted on the top of the plug-in block. The lever facilitates pressing the plug-in block downwards, thereby facilitating the removal of the mounting strip.
[0012] Furthermore, the clamp includes two clamping blocks slidably mounted on the mounting base and a screw that drives the two clamping blocks to move closer or further apart. The mounting base has a groove for mounting the clamping blocks, and the bottom of each clamping block has a slider that slidably engages with it. The slider has a threaded hole that engages with the screw. One end of the screw has a knob. A clamping groove, which is a V-shaped groove, is formed on the side where the two clamping blocks approach each other. The screw can quickly drive the two clamping blocks to clamp and fix the dashcam in place.
[0013] Furthermore, a slot is formed on the side wall of the test chamber, and a baffle is slidably installed at the slot; limit guide blocks are formed on both sides of the baffle, and limit guide grooves are formed on both sides of the slot to slide with the limit guide blocks; a cylinder for controlling the up and down sliding of the baffle is fixedly installed on the outer wall of the test chamber; the slot is located in the bumpy test section. The slot facilitates the installation of the mounting strip.
[0014] Furthermore, the traction mechanism includes a take-up reel, a traction rope, and a motor for driving the take-up reel to rotate; the take-up reel is rotatably mounted on the outer walls of both ends of the test box, and the traction rope is wound around the take-up reel with one end fixedly connected to the movable base. The traction mechanism can be used to quickly move the movable mechanism left and right.
[0015] With the above structure, the vehicle recorder testing device of the present invention, compared with the prior art, uses the traction mechanism at both ends of the test box to drive the moving mechanism to move back and forth on the guide rail of the test box. When passing through the bumpy test section, the vibration guide wheel and the first convex strip can make the placement platform vibrate rapidly up and down. When passing through the collision test section, the collision guide wheel swings left and right when it hits the second convex strips on the left and right sides, so that it continuously collides on the left and right sides. Therefore, under the alternating traction of the two traction mechanisms, the continuous dynamics of the collision process can be simulated, making the test results more accurate.

Detailed Implementation
[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. In addition, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.
[0033] like Figures 1 to 14As shown, this invention relates to a testing device for a dashcam 1, comprising a movable mechanism for mounting the dashcam 1, a test box 2 for housing the movable mechanism, and a traction mechanism 3 located on both sides of the test box 2 and driving the movable mechanism to move within the test box 2. Specifically, the movable mechanism includes a movable base 4 located below, a placement platform 5 located above, and multiple sets of telescopic rods 10 connected between the movable base 4 and the placement platform 5, the multiple sets of telescopic rods 10 being rectangularly distributed; the upper end of the telescopic rods 10 is provided with a first connecting ball joint 101 connected to the bottom of the placement platform 5, and the lower end is provided with a connecting ball joint 101 connected to the movable base 5. The top of the movable seat 4 is connected to a second connecting ball head 102. A first connecting seat that mates with the first connecting ball head 101 is provided at the bottom of the placement platform 5. The top of the movable seat 4 is provided with a second connecting seat that mates with the second connecting ball head 102. Under the constraint of the first and second connecting seats, the maximum tilt angle of the telescopic rod assembly 10 in all directions is 45°. Collision guide wheels 51 are rotatably installed at the four corners of the placement platform 5. A support rod 52 is also installed at the bottom of the placement platform 5, and a vibration guide wheel 521 is provided at the bottom of the support rod 52. The movable seat 4 includes a frame 41 and a... 41. The bottom of the frame has a movable roller 42; the vibrating guide wheel 521 can pass through the frame 41; the inner bottom wall of the test chamber 2 is provided with a guide rail 21, which is a C-shaped steel. The movable roller 42 is movably locked in the guide rail 21, so that the movable roller 42 can only roll back and forth within the guide rail 21, preventing the movable roller 42 from detaching from the guide rail 21; the test chamber 2 has a bump test section 22 located in the middle and collision test sections 23 located at both ends of the bump test section 22; a test platform 24 is formed on the inner bottom wall of the test chamber 2, and the vibrating guide wheel 521 abuts against the surface of the test platform 24. The two ends of 4 are formed with first guide slopes 241. The test platform 24 is provided with a number of first protrusions 242. The distance between adjacent first protrusions 242 is greater than the diameter of the vibrating guide wheel 521. When the vibrating guide wheel 521 passes through the first protrusions 242 in sequence, it can continuously drive the placement platform 5 to vibrate up and down. In addition, in order to achieve irregular vibration, the distance between adjacent first protrusions 242 can be different, and the height of the first protrusions 242 can also be different. The collision guide wheel 51 rolls into contact with the inner walls on both sides of the bump test section 22 to avoid the moving mechanism from tilting during the bump test.Several second protrusions 231 are formed on the two inner sidewalls of the collision test section 23. The second protrusions 231 on the two inner sidewalls are staggered, and the distance between adjacent second protrusions 231 is greater than the diameter of the collision guide wheel 51. The width of the collision test section 23 is greater than the width of the bump test section 22. A second guide slope 25 is formed between the collision test section 23 and the bump test section 22. When the moving mechanism passes through the collision test section 23, it loses the support of the inner wall of the test box 2 and the vibration guide wheel 521, and the telescopic rod assembly 10 will tilt. When the second protrusion 231 on the side wall of the test chamber 2 is impacted, the telescopic rod assembly 10 will continue to tilt to the opposite side and impact the second protrusion 231 on that side again. This cycle repeats, causing the placement platform 5 to vibrate left and right. Under the alternating traction of the two traction mechanisms 3, the continuous dynamics during the collision process can be simulated, making the test results more accurate. In addition, to reduce the wear of the collision guide wheel 51 and the vibration guide wheel 521, rubber pads can be wrapped around the circumferential surfaces of both the collision guide wheel 51 and the vibration guide wheel 521.
[0034] In this embodiment, the placement platform 5 is provided with multiple sets of mounting strips 6, which are arranged side by side. Multiple mounting seats 61 for mounting the dashcam 1 are provided on each mounting strip 6, and clamps 7 for fixing the dashcam 1 are provided on each mounting seat 61. The mounting strips 6 are movably connected to the placement platform 5. After the dashcam 1 is fixed to the mounting seat 61 at an angle, the mounting strips 6 are then installed on the placement platform 5. Specifically, a mounting groove 53 for mounting the mounting strips 6 is formed on the placement platform 5. The mounting groove 53 is a T-shaped groove, and a fixing component 8 is provided at the inlet end of the mounting groove 53. The fixing component 8 includes a plug-in block 81 movably mounted on the placement platform 5 and a compression spring 82. A receiving cavity 54 for the plug-in block 81 to slide is formed on the placement platform 5. The compression spring 82 is fixedly connected to the bottom of the plug-in block 81. The bottom of the mounting strip 6 has a part that cooperates with the plug-in block 81. The insertion slot 62; a pusher block 811 is formed on one side of the insertion block 81, and a through slot 55 is formed on the outer side of the placement platform 5 for the pusher block 811 to pass through; during operation, the insertion block 81 is first pressed down by the pusher block 811, and then the mounting strip 6 is inserted from the inlet end of the mounting slot 53. After it is inserted into place, the insertion block 81 is lifted and reset under the action of the compression spring 82 and inserted into the insertion slot 62, which can fix the mounting strip 6. In addition, in order to reduce the friction between the mounting strip 6 and the insertion block 81, a pulley 812 is rotatably installed on the top of the insertion block 81.
[0035] In this embodiment, the clamp 7 includes two clamping blocks 71 slidably mounted on the mounting base 61 and a screw 72 that drives the two clamping blocks 71 to move closer or further apart. The mounting base 61 has a sliding groove 611 for mounting the clamping blocks 71, and a slider 711 that slides and engages with the clamping blocks 71 is formed at the bottom of each clamping block 71. The slider 711 has a threaded hole that engages with the screw 72. The screw 72 has two threaded sections with opposite helical directions, and a knob 721 is provided at one end of the screw 72. A clamping groove 712 is formed on the side where the two clamping blocks 71 are close to each other. The slot 712 is a V-shaped slot, which can accommodate dash cams 1 of different sizes. The dash cam 1 can be quickly clamped by rotating the screw 72. In addition, a lithium battery can be installed in the mounting base 61, and a power socket is provided on the mounting base 61. After the dash cam 1 is installed and fixed on the mounting base 61, the power cord can be connected to the power socket so that the dash cam 1 can record normally. During the test, the recording effect of the dash cam 1 on bumpy road sections and after a collision is mainly tested to check whether the recorded picture will lose frames.
[0036] In this embodiment, to avoid installation interference caused by the side wall of the test chamber 2 when installing the mounting strip 6, a slot 26 is formed on the side wall of the test chamber 2, and a baffle 27 is slidably provided at the slot 26; limit guide blocks 271 are formed on both sides of the baffle 27, and limit guide grooves 261 that slide with the limit guide blocks 271 are formed on both sides of the slot 26; a cylinder 9 for controlling the up and down sliding of the baffle 27 is fixedly provided on the outer wall of the test chamber 2, the cylinder body of the cylinder 9 is fixedly connected to the side wall of the test chamber 2, and the piston rod is fixedly connected to one side of the baffle 27. Specifically, an mounting plate for mounting the cylinder body of the cylinder 9 is provided on the side wall of the test chamber 2, and a connecting plate connected to the piston rod of the cylinder 9 is provided on the side wall of the baffle 27; the slot 26 is located in the bumpy test section 22. When installing the mounting strip 6 on the placement platform 5, the baffle 27 is first lowered by the cylinder 9 to open the slot 26, and after installation, the baffle 27 is raised.
[0037] In this embodiment, the traction mechanism 3 includes a take-up reel 31, a traction rope 32, and a motor 33 that drives the take-up reel 31 to rotate. The take-up reel 31 is rotatably mounted on the outer walls of both ends of the test chamber 2. The traction rope 32 is wound around the take-up reel 31 and one end is fixedly connected to the moving base 4. Specifically, wheel frames for mounting the take-up reel 31 and brackets for mounting the motor 33 are provided on both side walls of the test chamber 2. The traction rope 32 can be made of steel wire rope. The moving mechanism can be quickly moved left and right by alternating operation of the traction mechanisms 3 on both sides.
[0038] The method of using this invention is as follows: First, install the dashcam 1 on the mounting strip 6, then insert the mounting strip 6 into the placement platform 5, then raise the baffle 27, and finally start the device to make the traction mechanisms 3 on both sides run alternately. When the moving mechanism passes through the bump test section 22, under the action of the first protrusion 242 and the vibration guide wheel 521, the placement platform 5 can be forced to vibrate up and down. When passing through the collision test section 23, under the action of the second protrusion 231 and the collision guide wheel 51, the placement platform 5 can be forced to swing left and right and collide. Under the alternating traction of the two traction mechanisms 3, the continuous dynamics during the collision process can be simulated, making the test results more accurate.
