DETAILED DESCRIPTION

[0023] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0024] The following is combined with Figure 1-Figure 6 This embodiment is described in further detail.

[0025] like Figure 1 As shown, in this embodiment, a detection device and a detection method for a brake harness of an automobile are provided, comprising a bottom plate 100, a support rod 110 is provided on the upper end surface of the bottom plate 100 and at four corners, a slide cavity 301 opening upward is provided in the support rod 110, a liftable workbench 120 is provided on the bottom plate 100, a detection mechanism for detecting the brake harness is provided on the upper end surface of the workbench 120, a slide rod 121 with one end extending into the corresponding slide cavity 301 is provided on the lower end surface of the workbench 120 and at four corners, and a slide rod 121 with one end extending into the corresponding slide cavity 301 is provided on the support rod 110 A lifting component is used to drive the workbench 120 to lift and lower. The lower end surface of the base plate 100 is provided with a relative notch 601, and a lifting component for lifting the base plate 100 is provided in the notch 601. A plurality of mounting grooves 401 are provided on the lower end surface of the base plate 100. A liftable mounting plate 400 is provided in each of the mounting grooves 401. Universal wheels 310 are provided on the lower end surfaces of the mounting plates 400. A driving component is provided on the slide bar 121. The lifting component drives the base plate 100 to lift, and the driving component drives the universal wheels 310 on the mounting plate 400 to extend out of the mounting grooves 401.

[0026] In this embodiment, the detection mechanism includes a harness detector 1 (the prior art) and a plug connection box 2 (the prior art). By plugging the brake harness into the plug connection box 2, and then using the harness detector 1 to detect the brake harness plugged into the plug connection box 2, the staff can distinguish unqualified brake harnesses. Among them, the workbench 120 is driven to be raised and lowered by the lifting component, so that the height of the workbench 120 can be adjusted according to the height of the staff, so that the height of the workbench 120 is adapted to the height of the staff. Compared with the existing detection equipment for automobile brake harnesses, when actually used, it can avoid the height of the workbench 120 not being adapted to the height of the staff, which makes it inconvenient for the staff to operate on the workbench 120; The universal wheel 310 is fixedly mounted on the mounting plate 400, and the bottom plate 100 is lifted by the lifting assembly in the notch 601, so that there is a certain gap between the bottom plate 100 and the contact surface. At this time, the driving assembly on the slide bar 121 can drive the mounting plate 400 to move downward, so that the universal wheel 310 on the mounting plate 400 extends out of the mounting slot 401, and then, the lifting of the bottom plate 100 by the lifting assembly is released, so that the universal wheel 310 supports the bottom plate 100. At this time, the staff can push the bottom plate 100 to move by pushing the workbench 120, so as to facilitate the transfer of the bottom plate 100 and the workbench 120, which is more convenient to use. When the bottom plate 100 is moved to a suitable position by the universal wheels 310, the driving assembly is released to drive the mounting plate 400, so that the mounting plate 400 drives the universal wheels 310 to retract into the mounting groove 401, so that the bottom plate 100 is positioned at the position after the transfer, thereby preventing the staff from accidentally pushing the workbench 120 or the bottom plate 100, causing the position of the bottom plate 100 to move again; A push handle 122 for pushing the bottom plate 100 to move is fixedly installed on the side wall of the workbench 120. The push handle 122 facilitates the staff to push the bottom plate 100 to move, thereby facilitating actual use. During actual use, the support rod 110 is fixedly mounted on the base plate 100, the slide rod 121 is fixedly mounted on the workbench 120, and one end of the slide rod 121 is inserted into the corresponding slide cavity 301, so that the workbench 120 is installed on the base plate 100. At the same time, the slide rod 121 is limited by the slide cavity 301, so that the workbench 120 is more stable during lifting and lowering adjustment.

[0027] like Figure 1-2As shown, in this embodiment, the lifting assembly includes a support plate 111 arranged on the support rod 110, a rotatable rotating rod 130 is arranged between the two support plates 111, and the two rotating rods 130 are respectively provided with relative rotating disks 131, and the side walls of the rotating disks 131 are respectively provided with pushing plates 132. The rotating rod 130 drives the rotating disk 131 to rotate, and the pushing plate 132 pushes the workbench 120 to be raised and lowered. A box body 140 is arranged between the two support rods 110, and a cavity 201 is arranged in the box body 140, and a rotating member for synchronously driving the two rotating rods 130 to rotate is arranged in the cavity 201.

[0028] In this embodiment, by setting the support plate 111, the rotating rod 130, the rotating disk 131, the pushing plate 132, the box body 140, the cavity 201 and the rotating member, the support plate 111 is fixedly installed on the support rod 110, the two ends of the rotating rod 130 are rotatably installed on the corresponding support plate 111 through the bearing seat, the rotating disk 131 is fixedly installed on the rotating rod 130, the pushing plate 132 is fixedly installed on the rotating disk 131, and the two ends of the box body 140 are respectively fixedly installed on the corresponding support rod 110. When the rotating rod 130 drives the rotating disk 131 to rotate, the pushing plate 132 on the rotating disk 131 rotates along the circumferential direction of the rotating disk 131. When the pushing plate 132 rotates, one end of the pushing plate 132 will push the lower end surface of the workbench 120 to move upward, thereby realizing the adjustment of the height of the workbench 120; The two rotating rods 130 are driven to rotate synchronously by the rotating member, so that the push plates 132 on the two rotating rods 130 can simultaneously adjust the lifting of the workbench 120, making the lifting of the workbench 120 more stable, thereby avoiding the asynchronous rotation of the two rotating rods 130, resulting in the tilting of the workbench 120 after lifting, thereby affecting the actual use; In actual use, a plurality of baffles 330 are fixedly mounted on the lower end surface of the workbench 120 and are used to limit the rotation of the push plate 132. When one end of the push plate 132 abuts against the baffle 330, the workbench 120 has moved up to the highest point.

[0029] like Figure 1-2 As shown, in this embodiment, one end of the two rotating rods 130 is extended into the cavity 201, and the rotating rods 130 located in the cavity 201 are provided with gears 210; The rotating part includes a threaded rod 220 which is arranged in the cavity 201 and can rotate. A rack 230 is provided on the threaded rod 220 which is opposite to and threadedly matched with the threaded rod 220. The rack 230 is meshed with the corresponding gear 210. The threaded rod 220 rotates to drive the two racks 230 to move closer to or away from each other, so that the two gears 210 drive the two rotating rods 130 to rotate synchronously.

[0030] In this embodiment, by setting the gear 210, the threaded rod 220 and the rack 230, the gear 210 is fixedly mounted on the rotating rod 130, and the two ends of the threaded rod 220 are rotatably mounted on the side wall of the cavity 201 through the bearing seat. The side wall of the rack 230 is slidably fitted with the side wall of the cavity 201. When the threaded rod 220 rotates, the two racks 230 move closer to or away from each other along the threaded rod 220, and the rack 230 moves to drive the corresponding gear 210 to rotate, and the rotation of the gear 210 drives the corresponding rotating rod 130 to rotate, thereby realizing the synchronous rotation of the two rotating rods 130. During actual use, one end of the threaded rod 220 is extended out of the box body 140, and a hand-cranked wheel 141 for driving the threaded rod 220 to rotate is fixedly installed on the extended end of the threaded rod 220. The staff can better drive the threaded rod 220 to rotate through the hand-cranked wheel 141, thereby facilitating actual use.

[0031] like Figure 1-6 As shown, in this embodiment, the lifting assembly includes a lifting plate 610 arranged in the slot 601, and a through rod 101 with one end penetrating the bottom plate 100 is provided at both ends of the lifting plate 610. A rotatable lifting rod 102 with one end threaded through the bottom plate 100 is provided on the upper end surface of the lifting plate 610. The lifting rod 102 rotates to drive the lifting plate 610 to extend out of the slot 601, thereby realizing the lifting of the bottom plate 100 by the lifting plate 610.

[0032] In this embodiment, by setting the lifting plate 610, the through rod 101 and the lifting rod 102, the through rod 101 is fixedly installed on the lifting plate 610, one end of the through rod 101 penetrates the bottom plate 100 to limit the two ends of the lifting plate 610, and one end of the lifting rod 102 is rotatably installed on the lifting plate 610 through the bearing seat. When the lifting rod 102 is threadedly rotated on the bottom plate 100, the lifting rod 102 drives the lifting plate 610 to extend out of the groove and lift the bottom plate 100, thereby realizing the separation of the bottom plate 100 from the contact surface; In actual use, when the lifting rod 102 drives the lifting plate 610 outside the slot 601 to slide into the slot 601, the bottom plate 100 will abut against the contact surface again.

[0033] like Figure 1-4 As shown, in this embodiment, a cavity 302 connected to the corresponding mounting groove 401 is provided on the bottom wall of the sliding cavity 301, an interception ring 410 is provided at the opening of the lower end of the cavity 302, and a mounting rod 420 with one end passing through the interception ring 410 and extending into the cavity 302 is provided on the mounting plate 400, a circular plate 421 is provided on the mounting rod 420 in the cavity 302, and a first spring 430 for pushing the circular plate 421 away from the interception ring 410 is sleeved on the mounting rod 420 between the circular plate 421 and the interception ring 410; The driving assembly includes a push rod 320 which is arranged under the sliding rod 121 and one end of which extends into the cavity 302. The sliding rod 121 drives the push rod 320 to move downward, and the push rod 320 pushes the circular plate 421 to move downward, so that the universal wheel 310 on the mounting plate 400 extends out of the mounting groove 401. A positioning box 150 is provided between the two support rods 110, and a positioning cavity 501 is provided in the positioning box 150. A positioning member is provided in the positioning cavity 501 for positioning the position of the push rod 320 after it moves downward.

[0034] In this embodiment, through the arrangement of the cavity 302, the interception ring 410, the mounting rod 420, the circular plate 421, the first spring 430, the push rod 320, the positioning box 150, the positioning cavity 501 and the positioning member, the mounting rod 420 is fixedly mounted on the mounting plate 400, the circular plate 421 is fixedly mounted on the mounting rod 420, the interception ring 410 is fixedly mounted at the lower end opening of the cavity 302, and the circular plate 421 and the first spring 430 are intercepted in the cavity 302, so that the circular plate 421 and the first spring 430 are realized. A spring 430 is installed in the cavity 302, the push rod 320 is fixedly installed on the slide bar 121, and both ends of the positioning box 150 are fixedly installed on the corresponding support rod 110. When the first spring 430 pushes the circular plate 421 away from the interception ring 410, the movement of the circular plate 421 will drive the installation rod 420 to move, and the movement of the installation rod 420 will drive the installation plate 400 to move toward the bottom wall of the installation groove 401, so that the universal wheel 310 on the installation plate 400 can always be located in the installation groove 401; When the lifting plate 610 lifts the bottom plate 100, the lifting assembly releases the driving force of the workbench 120, so that the workbench 120 begins to move downward by its own gravity. The downward movement of the workbench 120 can drive the push rod 320 to move downward through the sliding rod 121. When the push rod 320 moves downward, the lower end of the push rod 320 pushes the circular plate 421 downward. The circular plate 421 moves downward and drives the mounting plate 400 to move toward the opening of the mounting groove 401 through the mounting rod 420, so that the universal wheel 310 on the mounting plate 400 extends out of the mounting groove 401. At this time, the position of the push rod 320 after moving downward is positioned by the positioning member, so that the universal wheel 310 on the mounting plate 400 can always extend out of the mounting groove 401. Then, the lifting of the bottom plate 100 by the lifting plate 610 is released, so that the universal wheel 310 supports the bottom plate 100, and the bottom plate 100 can be pushed to transfer through the universal wheel 310. When the base plate 100 is moved by the universal wheels 310, the workbench 120 moves down to the lowest position, so that the center of gravity of the detection device for the automobile brake harness moves down, thereby making the base plate 100 more stable when moving; By releasing the positioning of the push rod 320 by the positioning member and releasing the push of the push rod 320 on the circular plate 421, the universal wheel 310 on the mounting plate 400 can be retracted into the mounting groove 401, and the support of the universal wheel 310 on the bottom plate 100 can be released; During actual use, before releasing the positioning of the push rod 320 by the positioning piece, the lifting plate 610 can be extended from the slot 601, and then, the positioning of the push rod 320 by the positioning piece is released. Finally, the lifting plate 610 is driven by the lifting rod 102 to move slowly into the slot 601, so that the base plate 100 also begins to slowly release from the contact surface, thereby avoiding the base plate 100 from quickly contacting the contact surface, causing the wire harness detector 1 and the plug connection box 2 on the workbench 120 to vibrate, thereby causing damage.

[0035] like Figure 1-5 As shown, in this embodiment, the push rod 320 is provided with a plug hole 321, the side wall of the positioning box 150 is provided with a relative limit block 510, and the limit block 510 is provided with a limit groove 511; The positioning member includes a movable plate 520 which is arranged in the positioning cavity 501 and is movable. The movable plate 520 is provided with an insertion rod 521 on the side wall facing the positioning rod and at both ends. A movable rod 530 is provided on the side wall of the movable plate 520, one end of which extends out of the positioning box 150 and is rotatable. A clamping plate 531 is provided on the protruding end of the movable rod 530. A second spring 540 is sleeved on the movable rod 530 in the positioning cavity 501. The second spring 540 is used to push the insertion rod 521 on the movable plate 520 to be inserted into the corresponding socket 321, so as to realize the positioning of the position of the push rod 320 after movement.

[0036] In this embodiment, by setting the jack 321, the limit block 510, the limit groove 511, the moving plate 520, the plug rod 521, the moving rod 530, the clamping plate 531 and the second spring 540, the limit block 510 is fixedly installed on the positioning box 150, the plug rod 521 is fixedly installed on the moving plate 520, the moving rod 530 is rotatably installed on the moving plate 520 through the bearing seat, and the clamping plate 531 is fixedly installed on the moving rod 530. When the second spring 540 pushes the moving plate 520 to move toward the support rod 110, the plug rod 521 on the moving rod 530 will be inserted into the jack 321 on the push rod 320, so as to realize the positioning of the position of the push rod 320; In actual use, when the push rod 320 does not need to be positioned, the second spring 540 will also push the insertion rod 521 on the movable plate 520 to be inserted into the cavity 302. At this time, the insertion rod 521 in the cavity 302 will affect the movement of the push rod 320. By pulling the movable rod 530 outward and rotating the movable rod 530, the two ends of the clamping plate 531 can be inserted into the corresponding limit grooves 511, and then the insertion rod 521 on the movable plate 520 is located in the side wall of the cavity 302 and will not extend into the cavity 302, thereby not affecting the movement of the push rod 320 in the cavity 302.
