Description

Technical Field

[0001] The invention relates to the technical field of crawler-type shock-absorbing chassis, in particular to a crawler-type shock-absorbing chassis. Background Art

[0002] The tracked shock-absorbing chassis has significant advantages due to its strong adaptability to complex and harsh terrain. It can effectively cope with a variety of extreme environments such as mountains, snow, swamps, river beaches, deserts and gullies. It not only demonstrates excellent off-road passing ability and high maneuverability and flexibility, but also has excellent shock resistance.

[0003] After searching, the patent document with publication number CN208306779U discloses a tracked shock-absorbing chassis, which includes a beam and a torsion spring. The torsion spring includes a torsion spring shaft and a rubber sleeve fixed outside the torsion spring shaft. The shock-absorbing chassis also includes a fixed clamping hoop plate and a detachable clamping hoop plate connected and fixed to the beam. The detachable clamping hoop plate and the fixed clamping hoop plate are detachably connected and fixed to fix the rubber sleeve.

[0004] The tracked shock-absorbing chassis uses a detachable clamping plate and a fixed clamping plate to connect the fixed torsion spring for easy replacement. However, in actual use, the torsion spring is not directly connected to the beam, which will reduce the shock-absorbing effect of the shock-absorbing spring on the chassis.

[0005] Therefore, a crawler-type shock-absorbing chassis is proposed to address the above problems. Summary of the invention

[0006] In order to make up for the shortcomings of the prior art and solve the problem that the shock-absorbing spring is not directly connected to the beam, resulting in a lower shock-absorbing effect of the shock-absorbing spring on the chassis, the present invention proposes a crawler-type shock-absorbing chassis.

[0007] A crawler-type shock-absorbing chassis, comprising a mounting frame, a mounting box being fixedly connected to the outer surface of the mounting frame, four mounting grooves being provided on the top of the mounting frame, first driven wheels being rotatably mounted on the inner surfaces of two of the mounting grooves, and driving wheels being rotatably mounted on the inner surfaces of the other two of the mounting grooves; It also includes a shock absorbing mechanism for facilitating the track to pass through uneven roads; The shock absorbing mechanism includes four rotating rods, which are rotatably installed at the bottom of the mounting frame and are divided into two groups of two. A second driven wheel is rotatably installed on one side of the rotating rod, a second damper is rotatably installed on one side of the rotating rod, the second damper is rotatably installed on one side of the mounting frame, a first damper is fixedly installed on one side of the mounting frame, a third driven wheel is rotatably installed on one side of the first damper, and the outer surfaces of the first driven wheel, the driving wheel, the second driven wheel and the third driven wheel are commonly meshed with tracks.

[0008] Preferably, protective plates are fixedly mounted on both sides of the mounting frame, and a plurality of heat dissipation holes are opened on one side of the protective plate.

[0009] Preferably, four first rotation grooves are formed at the bottom of the mounting frame, and the four rotating rods are rotatably mounted on the inner surfaces of the first rotation grooves respectively.

[0010] Preferably, four second rotation grooves are opened at the bottom of the mounting frame, and third dampers are rotatably mounted on the inner surfaces of the second rotation grooves, and one side of two third dampers are rotatably mounted together on one side of the third driven wheel.

[0011] Preferably, two synchronous wheels are rotatably mounted on one side of the mounting frame, and the two synchronous wheels are driven by a synchronous belt.

[0012] Preferably, a mounting plate is fixedly mounted on one side of the mounting frame, a motor is fixedly mounted on one side of the mounting plate, the motor output shaft is fixedly mounted on one side of one of the synchronous wheels, and the motor output shaft is fixedly mounted on one side of the driving wheel.

[0013] Preferably, a first bevel gear is fixedly mounted on one side of the other synchronous wheel, the first bevel gear is meshed with a second bevel gear, the second bevel gear is fixedly connected to a transmission shaft on one side, the outer surface of the transmission shaft is rotatably connected to a first mounting block, and the first mounting block is fixedly mounted on one side of the mounting frame.

[0014] Preferably, a disc is fixedly connected to one end of the transmission shaft, a rotating shaft is fixedly installed on one side of the disc, a transmission rod is rotatably installed on the outer surface of the rotating shaft, a second mounting block is fixedly installed on the bottom of the mounting frame, a sliding hole is provided on one side of the second mounting block, a cleaning rod is slidably installed on the inner surface of the sliding hole, a rotating groove is provided on the outer surface of the cleaning rod, and the transmission rod is rotatably installed on the inner surface of the rotating groove.

[0015] The present invention is beneficial in that: 1. The present invention drives the driving wheel to rotate through the motor output shaft, and the driving wheel can drive the crawler belt to rotate, and the crawler belt further drives the first driven wheel, the second driven wheel and the third driven wheel to rotate. At this time, the crawler belt can rotate stably, thereby achieving the purpose of driving the entire device to move through the crawler belt. When the motor output shaft drives the driving wheel to rotate, the motor output shaft will also drive the synchronous wheel to rotate. After the synchronous belt is driven, the two synchronous wheels start to rotate, one of the synchronous wheels drives the first bevel gear to rotate, the first bevel gear is meshed with the second bevel gear to drive the second bevel gear to rotate, and the second bevel gear drives the disc to rotate through the transmission shaft, and the rotating shaft set on one side of the disc will also rotate with the disc, and the rotating shaft further drives the transmission rod to rotate.

[0016] 2. The present invention rotates one end of the transmission rod on the inner surface of the rotating groove. Further, under the limiting action of the second mounting block, the transmission rod slides with the rotating groove on the inner surface of the sliding hole. The rotating groove that rotates synchronously with the track can clean up the garbage on the gap of the track. This can enhance the grip of the track, enable the track to rotate stably, and increase the passability of the track. The heat dissipation holes on the protective plate can dissipate heat from the track elements between the two protective plates.

[0017] 3. The present invention uses the second damper to squeeze the second driven wheel downward, thereby causing the second driven wheel to rotate in the first rotating groove with the rotating rod. The second driven wheel descends along with the descending crawler track, which can make the second driven wheel always close to the crawler track, so that the crawler track can rotate stably. At the same time, the two third dampers can also make the third driven wheel always keep in close contact with the crawler track. The angle formed by the two third dampers can also increase the stability of the third driven wheel, so that the third driven wheel can only move up and down close to the crawler track, avoiding the third driven wheel from tilting when encountering a bumpy road surface and causing damage to the first damper. Further, through the shock-absorbing treatment of the second driven wheel and the third driven wheel, it can be prevented that the vibration caused by the uneven road surface affects the mounting frame, thereby achieving shock absorption of the crawler-type shock-absorbing chassis.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 6 As shown, a crawler-type shock-absorbing chassis comprises a mounting frame 1, an outer surface of which is fixedly connected to a mounting box 10, and four mounting grooves 11 are opened on the top of the mounting frame 1, wherein first driven wheels 12 are rotatably mounted on the inner surfaces of two of the mounting grooves 11, and driving wheels 13 are rotatably mounted on the inner surfaces of the other two of the mounting grooves 11; a shock-absorbing mechanism is also included to facilitate the crawler track to pass through uneven roads; the shock-absorbing mechanism comprises four rotating rods 22, which are rotatably mounted on the bottom of the mounting frame 1, and are divided into two groups in pairs, a second driven wheel 23 is rotatably mounted on one side of the rotating rod 22, a second damper 26 is rotatably mounted on one side of the rotating rod 22, and the second damper 26 is rotatably mounted on one side of the mounting frame 1, a first damper 24 is fixedly mounted on one side of the mounting frame 1, and a third driven wheel 25 is rotatably mounted on one side of the first damper 24, and the outer surfaces of the first driven wheel 12, the driving wheel 13, the second driven wheel 23 and the third driven wheel 25 are meshed with a crawler track 32.

[0023] When using a device that moves via tracks, it is necessary to consider the shock-absorbing effect of the tracked shock-absorbing chassis. However, the shock-absorbing elements on the existing tracked shock-absorbing chassis do not directly contact the beam that bears the gravity, which will result in a reduction in the shock-absorbing effect of the shock-absorbing elements on the chassis and the structure on the beam.

[0024] When the present invention is in use, the mounting frame 1 carries the mounting box 10, and the driving wheel 13 rotates through the crawler 32 to transmit the two second driven wheels 23 and the first damper 24 on the same side to start rotating. During the crawler driving process, the two second driven wheels 23 and the third driven wheel 25 will always maintain close contact with the crawler 32 under the action of the second damper 26 and the first damper 24. When encountering a pothole road, the second damper 26 and the first damper 24 will extend, so that the second driven wheel 23 and the first damper 24 can always maintain contact with the crawler 32. When encountering a raised road, the second driven wheel 23 and the first damper 24 extend, and then the crawler 32 is always in contact with the ground through the second driven wheel 23 and the first damper 24.

[0025] Further, such as Figure 2 As shown, protective plates 3 are fixedly mounted on both sides of the mounting frame 1 , and a plurality of heat dissipation holes 31 are opened on one side of the protective plate 3 .

[0026] When the present invention is in use, the protective plate 3 can protect the components that drive the crawler belt 32 to rotate, so as to prevent foreign matter from entering between the two protective plates 3, or foreign matter from being on the top of the crawler belt 32, which will cause the second driven wheel 23 and the third driven wheel 25 to reduce the driving effect of the crawler belt 32, and even cause the transmission of the crawler belt 32 to malfunction. When in use, the components driven by the crawler belt 32 can be cooled through a plurality of heat dissipation holes 31, so as to prevent the transmission effect from being reduced due to excessive temperature of the transmission components.

[0027] Further, such as Figure 3 and Figure 4 As shown, four first rotation grooves 21 are opened at the bottom of the mounting frame 1, and the four rotating rods 22 are respectively rotatably mounted on the inner surfaces of the first rotation grooves 21; The bottom of the mounting frame 1 is provided with four second rotation grooves 27 , and a third damper 271 is rotatably mounted on the inner surface of the second rotation groove 27 . One side of two third dampers 271 are rotatably mounted on one side of the third driven wheel 25 .

[0028] When the present invention is in use, the rotating rod 22 can rotate on the inner surface of the first rotating groove 21. The rotating rod 22 is used to support the second driven wheel 23. The second damper 26 cooperates with the rotating rod 22 to enable the second driven wheel 23 to remain stable during use. When the second driven wheel 23 encounters bumpy road conditions, the second damper 26 pulls the rotating rod 22 to rotate on the inner surface of the first rotating groove 21, and can also enable the second driven wheel 23 to remain stable, thereby increasing the passability and stability of the track 32.

[0029] Further, such as Figure 6 As shown, two synchronous wheels 42 are rotatably mounted on one side of the mounting frame 1, and the two synchronous wheels 42 are driven by a synchronous belt 421; A mounting plate 41 is fixedly mounted on one side of the mounting frame 1, a motor 4 is fixedly mounted on one side of the mounting plate 41, an output shaft of the motor 4 is fixedly mounted on one side of a synchronous wheel 42, and an output shaft of the motor 4 is fixedly mounted on one side of the driving wheel 13; A first bevel gear 43 is fixedly mounted on one side of the other synchronous wheel 42, the first bevel gear 43 is meshed with a second bevel gear 44, a transmission shaft 45 is fixedly connected to one side of the second bevel gear 44, a first mounting block 46 is rotatably connected to the outer surface of the transmission shaft 45, and the first mounting block 46 is fixedly mounted on one side of the mounting frame 1; A disc 451 is fixedly connected to one end of the transmission shaft 45, a rotating shaft 47 is fixedly installed on one side of the disc 451, a transmission rod 48 is rotatably installed on the outer surface of the rotating shaft 47, a second mounting block 49 is fixedly installed on the bottom of the mounting frame 1, a sliding hole 491 is opened on one side of the second mounting block 49, a cleaning rod 492 is slidably installed on the inner surface of the sliding hole 491, a rotating groove 493 is opened on the outer surface of the cleaning rod 492, and the transmission rod 48 is rotatably installed on the inner surface of the rotating groove 493.

[0030] When the present invention is in use, the output shaft of the motor 4 drives the driving wheel 13 to rotate through the crawler belt 32, and the second driven wheel 23 and the third driven wheel 25 start to rotate, so that the motor 4 can drive the crawler belt 32 to move. When in use, the output shaft of the motor 4 rotates and also drives the synchronous wheel 42 to rotate. After the synchronous belt 421 is driven, the two synchronous wheels 42 start to rotate. The synchronous wheel 42 drives the first bevel gear 43 to rotate, and the first bevel gear 43 drives the second bevel gear 44 to rotate. The second bevel gear 44 drives the disc 451 to rotate through the transmission shaft 45. The eccentric position of the disc 451 is set The rotating shaft 47 also rotates with the disc 451, and the rotating shaft 47 moves with the transmission rod 48. One end of the transmission rod 48 rotates on the inner surface of the rotating groove 493. At the same time, the transmission rod 48 also drives the cleaning rod 492 to slide on the inner surface of the sliding hole 491. One end of the cleaning rod 492 can pass through the gap on the track 32 to clean the garbage accumulated in the gap of the track 32. Under the transmission action of the synchronous belt 421, the movement frequency of the cleaning rod 492 is related to the rotation frequency of the track 32. Therefore, the cleaning rod 492 will not affect the rotation of the track 32 and can continue to clean the surface of the track 32.

[0031] Working principle: First, the output shaft of the motor 4 drives the driving wheel 13 to rotate, and the driving wheel 13 can drive the crawler belt 32 to rotate. The crawler belt 32 further drives the first driven wheel 12, the second driven wheel 23 and the third driven wheel 25 to rotate. At this time, the crawler belt 32 can rotate stably, thereby achieving the purpose of driving the entire device to move through the crawler belt 32. When the output shaft of the motor 4 drives the driving wheel 13 to rotate, the output shaft of the motor 4 will also drive the synchronous wheel 42 to rotate. After the synchronous belt 421 drives the two synchronous wheels 42 to start rotating, one of the synchronous wheels 42 drives the first bevel gear 43 to rotate, and the first bevel gear 43 is meshed with the second bevel gear 44 to drive The second bevel gear 44 rotates, and the second bevel gear 44 drives the disc 451 to rotate through the transmission shaft 45. The rotating shaft 47 set on one side of the disc 451 will also rotate with the disc 451. The rotating shaft 47 further drives the transmission rod 48 to rotate. One end of the transmission rod 48 rotates on the inner surface of the rotating groove 493. Further, under the limiting effect of the second mounting block 49, the transmission rod 48 slides on the inner surface of the sliding hole 491 with the rotating groove 493. The rotating groove 493 that rotates synchronously with the crawler 32 can clean up the garbage on the gap of the crawler 32. This can enhance the grip of the crawler 32, enable the crawler 32 to rotate stably, and increase the passability of the crawler 32.

[0032] When the crawler 32 encounters a pitted road surface during use, the second damper 26 will squeeze the second driven wheel 23 downward, thereby causing the second driven wheel 23 to rotate with the rotating rod 22 in the first rotating groove 21, and the second driven wheel 23 will descend along with the descending crawler 32, which can make the second driven wheel 23 always close to the crawler 32, so that the crawler 32 can rotate stably, and at the same time, the two third dampers 271 can also make the third driven wheel 25 always keep in close contact with the crawler 32, and the angle formed by the two third dampers 271 can also The stability of the third driven wheel 25 can be increased so that the third driven wheel 25 can only move up and down close to the track 32, thereby preventing the third driven wheel 25 from tilting when encountering a bumpy road surface, thereby preventing the first damper 24 from being damaged. Further, through the shock-absorbing treatment of the second driven wheel 23 and the third driven wheel 25, the vibration caused by the uneven road surface from affecting the mounting frame 1 can be avoided, thereby achieving shock absorption of the tracked shock-absorbing chassis, and the heat dissipation holes 31 on the protective plate 3 can dissipate the heat of the track elements between the two protective plates 3.
