Description

Technical Field

[0001] This invention relates to the field of electromechanical equipment protection technology, specifically an automatic tilting protection structure for the roof of a vehicle. Background Technology

[0002] Special operation vehicles are usually equipped with onboard equipment, such as radar, which is usually installed on the top of the vehicle. To protect the equipment, an openable protective structure is installed. Most existing protective structures are operated by flipping open.

[0003] The flip protection structure needs to ensure high precision when starting, and needs to be supported and locked in the open and closed states. The existing operation methods generally use electric or manual opening, which is difficult to open in the event of a power failure, and is prone to inaccurate positioning during use. With vehicle vibration, the conventional locking structure is also prone to falling off. Therefore, structural improvement is required. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this invention is to provide an automatic tilting protection structure for the roof of a vehicle, so as to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An automatic tilting protection structure for the roof of a vehicle is provided. The automatic tilting protection structure is installed on the roof of the vehicle body. The roof of the vehicle body has a through slot, and the sides of the slot have symmetrically arranged manual buckles. The automatic tilting protection structure includes a movable protective cover, a locking module, a drive module, a main boom, and a balance bar.

[0007] The protective cover has fixedly connected outer latches on both sides of its exterior. When manually closed, the manual latch is fastened to the outer latch. The protective cover has a fixedly connected inner latch at the front end of its interior.

[0008] One end of the main boom and balance bar is rotatably connected to the protective cover. The locking module includes a movable rod and an electric telescopic rod. The electric telescopic rod pulls the movable rod to rotate. The top of the movable rod is provided with a fixedly connected pressure block. After the pressure block rotates and closes, it presses against the inner lock.

[0009] The drive module includes a four-axis reducer, a first bearing housing, a second bearing housing, a third bearing housing, a first drive shaft, and a second drive shaft. The first drive shaft passes through the first bearing housing, and the other end of the main boom is fixedly connected to the first drive shaft. The other end of the balance bar is rotatably connected to the third bearing housing. The four-axis reducer drives the first drive shaft and the second drive shaft to rotate. The second drive shaft can be rotated manually.

[0010] The first drive shaft has an outer detection frame on its outer side, a rotating detection ring inside the outer detection frame, a proximity sensor arranged along the axial direction of the detection ring inside the outer detection frame, the proximity sensor being fixedly connected to the outer detection frame, the detection ring being fixedly connected to the first drive shaft by fasteners, and an axially arranged "T"-shaped detection piece on the outer side of the detection ring.

[0011] Preferably, the front end of the slot is provided with an array of soft pads, which are placed above the slot when the protective cover is closed, and support the protective cover when the protective cover is open.

[0012] Preferably, the inner latch has a slot at its front end.

[0013] Preferably, the locking module further includes a second contact. The movable rod is rotatably connected to the inside of the vehicle body via a rotating shaft. The second contact is fixedly connected to the inside of the vehicle body. A telescopic electromagnetic lock is fixedly connected to the back of the movable rod. A positioning pin is fixedly connected to the telescopic end of the telescopic electromagnetic lock. A first contact is fixedly connected to the front of the movable rod. When the movable rod is closed, the pressure block presses against the inner latch. The first contact and the second contact come into contact. The telescopic electromagnetic lock is activated, pushing the positioning pin forward to insert into the slot.

[0014] Preferably, the tail end of the electric telescopic rod is rotatably connected to the interior of the vehicle body, the telescopic end of the electric telescopic rod is provided with a fixedly connected mounting post, the mounting post is provided with a slidingly fitted telescopic post, the telescopic post and the mounting post are provided with springs on the outside, and one end of the telescopic post is rotatably connected to the movable rod.

[0015] Preferably, the telescopic column has a third contact at the other end and a fourth contact inside the mounting column. When the spring is reduced to its shortest length, the third and fourth contacts come into contact.

[0016] Preferably, the second drive shaft is fixedly connected to a set of drive shafts of the right-angle reducer, and a third drive shaft is fixedly connected to another set of drive shafts of the right-angle reducer.

[0017] Preferably, when the first drive shaft rotates, it drives the detection ring to rotate synchronously. The proximity sensor senses the rotation of the detection plate and counts the movement.

[0018] The beneficial effects of this invention are:

[0019] The present invention provides an automatic flip-up protective structure for the roof of a vehicle, which can open and close the protective cover. The entire opening and closing process is highly stable, and a multi-locking structure design is adopted when closing to prevent loosening under vibration. In addition, it adopts both manual and electric drive to prevent the protective cover from failing to open in the event of a power outage.

[0020] This invention employs multiple detection structures when the protective cover is opened and closed. Operation can only be performed when the first contact and the second contact, and the third contact and the fourth contact are simultaneously in contact or disconnected, reducing the probability of jamming. Furthermore, the locking structure uses a soft drive. The telescopic electromagnetic lock pulls the positioning pin back and withdraws it from the slot. The electric telescopic rod pulls the mounting column back, and the telescopic column extends. The third contact and the fourth contact disengage. After the spring extends, it begins to pull the movable rod to rotate and open. The first contact and the second contact disengage, and the pressure block disengages from the inner lock, avoiding damage to the internal structure caused by hard pushing.

[0021] In this invention, during the opening of the protective cover, the first drive shaft rotates, causing the detection ring to rotate synchronously. The proximity sensor senses the rotation of the detection plate and counts it. The counting interval and the number of counts of the proximity sensors inside the two sets of detection outer frames must be the same, thereby ensuring that the rotation of the two symmetrical sets of first drive shafts is synchronized, and avoiding the symmetrical main booms from not rotating synchronously due to loose couplings and deformation of the first drive shafts.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 6 As shown, this embodiment provides an automatic tilting protection structure for the roof of a vehicle. The automatic tilting protection structure is installed on the top of the vehicle body 1 and can be switched on and off in both automatic and manual modes.

[0032] Specifically, the top of the vehicle body 1 is provided with a through slot 11, in which equipment such as vehicle radar and monitor can be placed. The sides of the slot 11 are provided with symmetrically arranged manual buckles 12, and the front end of the slot 11 is provided with arrayed soft pads 13.

[0033] Furthermore, the automatic tilting protection structure includes a movable protective cover 2, a locking module, a drive module 3, a main boom 4, and a balance bar 5;

[0034] Specifically, one end of the main boom 4 and the balance bar 5 is rotatably connected to the protective cover 2. When the protective cover 2 is closed, it rests above the slot 11. Both sides of the outer side of the protective cover 2 are provided with fixedly connected outer latches. When the protective cover 2 is manually closed, the manual latch 12 can be fastened to the outer latches, thereby fixing the position of the protective cover 2. When the protective cover 2 is open, the soft pad 13 supports the protective cover 2. The front end of the inner side of the protective cover 2 is provided with a fixedly connected inner latch 21, and the front end of the inner latch 21 is provided with a slot 211.

[0035] Furthermore, the locking module includes a movable rod 14, an electric telescopic rod 15, and a fixed second contact 18. The movable rod 14 is rotatably connected to the interior of the vehicle body 1 via a rotating shaft. The second contact 18 is fixedly connected to the interior of the vehicle body 1. The top of the movable rod 14 is provided with a fixedly connected pressure block 141. The bottom of the movable rod 14 is provided with a fixedly connected mounting block 142. The back of the movable rod 14 is provided with a fixedly connected telescopic electromagnetic lock 17. The telescopic end of the telescopic electromagnetic lock 17 is provided with a fixedly connected positioning pin 171. The front of the movable rod 14 is provided with a fixedly connected first contact 143.

[0036] When the movable lever 14 is closed, the pressure block 141 presses against the inner latch 21. At this time, the positioning pin 171 is concentric with the slot 211, the first contact 143 contacts the second contact 18, and sends an electrical signal to the PLC control system. The telescopic electromagnetic lock 17 starts to push the positioning pin 171 forward and insert it into the slot 211, thereby locking the movable lever 14 with the inner latch 21.

[0037] The tail end of the electric telescopic rod 15 is rotatably connected to the interior of the vehicle body 1. The telescopic end of the electric telescopic rod 15 is provided with a fixedly connected mounting post 16. The mounting post 16 is provided with a slidingly fitted telescopic post 161. The telescopic post 161 and the mounting post 16 are provided with a spring 162 on the outside. One end of the spring 162 is fixedly connected to the telescopic post 161, and the other end of the spring 162 is fixedly connected to the mounting post 16. One end of the telescopic post 161 is rotatably connected to the mounting block 142. The electric telescopic rod 15 pulls the movable rod 14 to rotate.

[0038] The telescopic column 161 has a third contact 163 at the other end, and the mounting column 16 has a fourth contact 164 inside. The spring 162 drives the telescopic column 161 and the mounting column 16 to unfold to an initial specified length. At this time, the third contact 163 and the fourth contact 164 are not in contact. When the spring 162 is compressed and shortens its length, the third contact 163 moves forward and approaches the fourth contact 164. When the spring 162 shrinks to its shortest length, the third contact 163 and the fourth contact 164 make contact and send an electrical signal to the PLC control system.

[0039] Furthermore, the drive module 3 includes a four-axis reducer 31, a right-angle reducer 32, and a first bearing housing 33, a second bearing housing 35, and a third bearing housing 36. The first end face of the four-axis reducer 31 is provided with a motor 311 fixedly connected to it. The motor 311 drives the drive shaft of the four-axis reducer 31 to rotate synchronously. The three sets of driven shafts of the four-axis reducer 31 are respectively provided with a first drive shaft 312 and a second drive shaft 313 fixedly connected to them. There are two sets of first drive shafts 312, which are symmetrically arranged relative to the four-axis reducer 31. A detection outer frame 34 is provided on the outside of the first drive shaft 312.

[0040] The second drive shaft 313 is fixedly connected to a set of drive shafts of the right-angle reducer 32. The other set of drive shafts of the right-angle reducer 32 is provided with a fixedly connected third drive shaft 351. The third drive shaft 351 passes through the second bearing seat 35 and has an inner groove at one end. By inserting a wrench into the inner groove, the third drive shaft 351, the second drive shaft 313 and the first drive shaft 312 can be driven to rotate synchronously.

[0041] The first drive shaft 312 passes through the first bearing seat 33. One end of the first drive shaft 312 is fixedly connected to the other end of the main boom 4. The other end of the balance bar 5 is inserted into the third bearing seat 36 and rotatably connected to it. The motor 311 can drive the first drive shaft 312, the second drive shaft 313, the third drive shaft 351, and the main boom 4 to rotate synchronously. When the main boom 4 rotates, it pulls the protective cover 2 to move synchronously through the balance bar 5. When the motor 311 is damaged or the power is cut off, it can be manually used through the third drive shaft 351 to open and close the protective cover 2.

[0042] The outer detection frame 34 has a rotating detection ring 342 inside, and a proximity sensor 341 arranged along the axial direction of the detection ring 342 inside the outer detection frame 34. The proximity sensor 341 is fixedly connected to the outer detection frame 34. The detection ring 342 is fixedly connected to the first drive shaft 312 by fasteners. The outer side of the detection ring 342 has an axially arranged "T"-shaped detection piece 343. When the first drive shaft 312 rotates, it drives the detection ring 342 to rotate synchronously. The proximity sensor 341 senses the rotation of the detection piece 343 and counts. The counting interval and the number of counts of the proximity sensors 341 inside the two sets of outer detection frames 34 must be the same, so as to ensure that the rotation of the two sets of first drive shafts 312 is synchronized and to avoid the main boom 4 from not rotating synchronously due to loose coupling and deformation of the first drive shaft 312.

[0043] Working principle:

[0044] In use, when initially closed, the protective cover 2 is closed and positioned above the slot 11. When needed, first disengage the manual latch 12 and the outer latch. The telescopic electromagnetic lock 17 pulls the positioning pin 171 backward and withdraws from the slot 211. The electric telescopic rod 15 pulls the mounting column 16 backward, and the telescopic column 161 extends. The third contact 163 and the fourth contact 164 disengage. After the spring 162 extends, it begins to pull the movable rod 14 to rotate and open. The first contact 143 and the second contact 18 disengage, and the pressure block 141 disengages from the inner latch 21.

[0045] Then, the motor 311 starts and drives the first drive shaft 312, the second drive shaft 313, the third drive shaft 351, and the main boom 4 to rotate synchronously. When the main boom 4 rotates, it pulls the protective cover 2 open through the balance bar 5. If the motor 311 is damaged or loses power, it can be manually used through the third drive shaft 351 to drive the protective cover 2 to open. When the first drive shaft 312 rotates, it drives the detection ring 342 to rotate synchronously. The proximity sensor 341 senses the rotation of the detection piece 343 and counts it. The counting interval and the number of counts of the proximity sensors 341 inside the two sets of detection outer frames 34 must be the same. If the interval and the count are different, an electrical signal is sent to the PLC control center, the display issues a warning, and the worker needs to check.

[0046] When closed, the protective cover 2 is closed by motor 311 or third drive shaft 351. After closing, the electric telescopic rod 15 pushes the mounting column 16 forward and pushes the movable rod 14 to reverse. After the pressure block 141 presses on the inner lock 21, the first contact 143 contacts the second contact 18. The spring 162 begins to be compressed and shortens its length. The third contact 163 moves forward and approaches the fourth contact 164. When the spring 162 shrinks to its shortest length, the third contact 163 and the fourth contact 164 contact and send an electrical signal to the PLC control system. Then the telescopic electromagnetic lock 17 is activated and pushes the positioning pin 171 into the slot 211. The display shows that the protective cover 2 is fully locked. Then, the manual buckle 12 and the outer lock are manually locked.
