DETAILED DESCRIPTION

[0030] 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.

[0031] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0032] For example, see Figures 1 to 12 A trailer dual-mode single-bridge interconnected active hydraulic suspension mechanism comprises a base plate 1, both ends of the base plate 1 are fixed with symmetrically arranged support arms 101, the bottom of the base plate 1 is provided with two flip plates 3, and the two flip plates 3 are rotatably connected to the support arms 101; A shock absorbing component, which is disposed at both ends of the substrate 1 and connects the two flip plates 3 and both ends of the substrate 1; An adjusting component, the adjusting component is installed at the bottom of the base plate 1, the adjusting component is connected to the two flip plates 3, and the two flip plates 3 are driven to flip relative to each other through the adjusting component; A mounting base 6 is fixed to the bottom of the base plate 1 , and a driving component is mounted on the mounting base 6 , and the driving component is connected to the vehicle driving wheel and the adjusting component.

[0033] In the embodiment of the present invention, the shock absorbing assembly absorbs the bumps during the vehicle travel, so that the vehicle has a more comfortable driving experience; When the adjustment component is working, the two flip plates 3 are driven to flip in opposite directions. When the two flip plates 3 flip, the two rear drive wheels of the vehicle are driven to flip relative to each other while adjusting the shock absorbing component. When the driving component is working, the two rear driving wheels of the vehicle are driven to rotate synchronously, so that the vehicle is driven forward / backward through the rotation of the driving wheels. When the adjusting component is working, when the two rear driving wheels are driven to flip, the two rear driving wheels are driven to rotate relative to each other. By adjusting the drive to an inclined state, when the vehicle enters the water, the two relatively rotating driving wheels give the vehicle propulsion.

[0034] The shock absorbing assembly includes an upper swing arm 2 and a lower swing arm 201, wherein the lower swing arm 201 and the upper swing arm 2 are rotatably connected to both ends of the flip plate 3, and a disc body 7 is rotatably mounted on one end of the lower swing arm 201 and the upper swing arm 2 away from the flip plate 3; The upper swing arm 2 and the lower swing arm 201 are both provided with a through slot 202; The lower swing arm 201 is rotatably mounted with a shock absorber 5 , and the shock absorber 5 passes through the through slot 202 on the upper swing arm 2 and is rotatably connected to one end of the base plate 1 . A shock absorbing spring 501 is sleeved on the shock absorber 5 .

[0035] In the embodiment of the present invention, when the adjustment component is working, the flip plate 3 is driven to flip, and when the flip plate 3 flips, the upper swing arm 2 is driven to move toward the disk body 7, and the lower swing arm 201 is driven to move away from the disk body 7, thereby driving the disk body 7 to flip from the upright state to the inclined state, see Figure 4 and Figure 5 ; Under normal conditions, the driving wheels are in an upright state. In the current state, after entering the water, the two driving wheels rotate to drive the vehicle forward, but at this time the water flow will contact the bottom of the vehicle, which will cause a significant reduction in thrust. The two driving wheels are adjusted to an inclined state to solve the above problem. Secondly, the method of driving the upper swing arm 2 and the lower swing arm 201 to drive the disk body 7 to flip by the flip plate 3 has a more reliable stability than the existing electronic device driving the two driving wheels to flip. Secondly, the angle of the disk body 7 from the starting end adjustment axis to the end of the stroke is greater than 80 degrees by using this adjustment method, so that the driving wheel is closer to the horizontal state; Among them, the shock absorber 5 and the shock absorbing spring 501 are used to support the vehicle. Since the upper swing arm 2 and the lower swing arm 201 are for synchronous movement, there is a linkage relationship between the two. The shock absorber 5 and the shock absorbing spring 501 are connected to the lower swing arm 201, and the shock absorbing force thereof can act on the upper swing arm 2 at the same time; When the driving wheel and the disc body 7 are adjusted from the upright state to the inclined state, the shock absorber 5 and the shock absorbing spring 501 will be gradually compressed.

[0036] The adjustment assembly includes two bidirectional screw rods 303 rotatably mounted on the bottom of the base plate 1, the two bidirectional screw rods 303 are connected by a first transmission chain 304, both ends of the two bidirectional screw rods 303 are sleeved with sliders 302 threadedly matched therewith, and the two sliders 302 are slidably connected to the bottom of the base plate 1; The bottom of the two sliders 302 are both hinged with a transmission plate 301, and one end of the two transmission plates 301 away from the sliders 302 is hinged to the flip plate 3, and the two sliders 302 are connected to the driving assembly; One of the bidirectional screw rods 303 is connected to a driving member.

[0037] In the embodiment of the present invention, the driving member is a device that drives one of the bidirectional screw rods 303 to rotate, and the specific structure thereof is not specifically limited by the present invention; When the driving member is working, one of the two-way screw rods 303 is driven to rotate. When one of the two-way screw rods 303 rotates, the first transmission chain 304 drives the second two-way screw rod 303 to rotate, so as to drive the two two-way screw rods 303 to rotate synchronously. When the bidirectional screw rod 303 rotates, the two sliders 302 are driven to rotate relative to each other / oppositely by cooperating with the thread of the slider 302. When the two sliders 302 rotate relative to each other, the two flip plates 3 are pulled to rotate by the transmission plate 301, and vice versa, the two flip plates 3 are driven to reset. When the two sliders 302 move relative to each other, the driving assembly is also driven to work. The connection position between the transmission plate 301 and the flip plate 3 is the bottom of one side of the flip plate 3 .

[0038] Embodiment 2, which is distinguished from Embodiment 1 in that: the driving assembly comprises a No. 1 transmission rod 4 and a No. 2 transmission rod 401 rotatably mounted on the support arm 101, the No. 2 transmission rod 401 and the No. 1 transmission rod 4 are coaxially fixed with a universal coupling 403 at opposite ends, the universal coupling 403 is coaxially fixed with a No. 3 transmission rod 402 at one end away from the No. 2 transmission rod 401 and the No. 1 transmission rod 4, and the No. 3 transmission rod 402 is rotatably connected to the disk body 7; The first transmission rod 4 and the second transmission rod 401 are connected to form a power output assembly between the first transmission rod 4 and the second transmission rod 401 .

[0039] In the embodiment of the present invention, the power of the engine is transmitted to the No. 1 transmission rod 4 and the No. 2 transmission rod 401 through the power output assembly, so that the No. 2 transmission rod 401 and the No. 1 transmission rod 4 rotate synchronously, when the No. 2 transmission rod 401 rotates, the No. 3 transmission rod 402 is driven to rotate through the universal coupling 403, and when the No. 3 transmission rod 402 rotates, the driving wheel is driven to rotate through another universal coupling 403; Among them, by adopting this method, when the vehicle is bumpy or the driving wheel is adjusted, the power of the No. 2 transmission rod 401 and the No. 2 transmission rod 401 and the driving wheel will not be cut off. The method of transmitting the driving force to the driving wheel is a relatively mature existing technology and will not be elaborated on here.

[0040] The power output assembly includes a slide 901 fixed to the bottom of the mounting seat 6, a fifth transmission rod 9 is movably mounted in the slide 901, and the fifth transmission rod 9 is connected to the first transmission rod 4 and the second transmission rod 401 through a power distribution assembly; The fifth transmission rod 9 is connected to the slider 302 via a follower assembly; A slide bar 903 is coaxially slidably mounted on one end of the No. 5 transmission rod 9 away from the slide cylinder 901, and a plurality of transmission bars 9012 are equidistantly fixed on the circumference of the slide bar 903, and the transmission bars 9012 are slidably matched with transmission grooves 9013 opened on the inner wall of the No. 5 transmission rod 9.

[0041] In the embodiment of the present invention, the slide bar 903 is connected to the power delivery end of the engine, and drives the slide bar 903 to rotate when the engine is working. When the slide bar 903 rotates, the transmission bar 9012 and the transmission groove 9013 cooperate to drive the fifth transmission rod 9 to rotate. When the fifth transmission rod 9 rotates, the power is transmitted to the first transmission rod 4 and the second transmission rod 401 through the power distribution component to drive the first transmission rod 4 and the second transmission rod 401 to rotate; When the two sliders 302 move relative to each other, the two No. 1 transmission rods 4 are driven to flip and drive the follower assembly to work, and the distribution mode of the power distribution assembly is switched by the follower assembly: Distribution method 1: when the fifth transmission rod 9 rotates, the first transmission rod 4 and the second transmission rod 401 are driven to rotate in the same direction through the power distribution assembly. This power distribution method is when the driving wheel is in the state; Distribution method 2: when the fifth transmission rod 9 rotates, the first transmission rod 4 and the second transmission rod 401 are driven to rotate relative to each other through the power distribution assembly. This power distribution method is when the driving wheel is adjusted to a tilted state; The movable connection between the fifth transmission rod 9 and the slide cylinder 901 means that the fifth transmission rod 9 can rotate or axially slide in the slide cylinder 901 .

[0042] The power distribution assembly includes a second bevel gear 905 and a first bevel gear 904 coaxially fixed on the fifth transmission rod 9, and the first bevel gear 904 and the second bevel gear 905 are arranged opposite to each other; A fifth bevel gear 908 is coaxially fixed to the opposite ends of the first transmission rod 4 and the second transmission rod 401, and the two fifth bevel gears 908 cooperate with the second bevel gear 905; A third bevel gear 906 is coaxially fixed on the first transmission rod 4, a fourth bevel gear 907 is rotatably mounted on the second transmission rod 401, the fourth bevel gear 907 is connected to the second transmission rod 401 via a direction adjusting member, and the first bevel gear 904 cooperates with the third bevel gear 906 and the fourth bevel gear 907.

[0043] In the embodiment of the present invention, when the No. 5 transmission rod 9 rotates, it drives the No. 2 bevel gear 905 and the No. 1 bevel gear 904 to rotate synchronously. When the No. 2 bevel gear 905 is meshed with the two No. 5 bevel gears 908, the two No. 5 bevel gears 908 are driven to rotate synchronously in the same direction. The corresponding No. 1 transmission rod 4 and the No. 2 transmission rod 401 and the two power wheels rotate synchronously in the same direction. When the No. 1 bevel gear 904 is meshed with the No. 3 bevel gear 906 and the No. 4 bevel gear 907, the No. 2 bevel gear 905 is disengaged from the No. 5 bevel gear 908, so as to achieve the desired effect through the No. 1 bevel gear 90 The meshing of the bevel gear 4 with the fourth bevel gear 907 and the third bevel gear 906 drives the two to rotate synchronously in the same direction. When the third bevel gear 906 rotates, the first transmission rod 4 is driven to rotate accordingly. When the fourth bevel gear 907 rotates, since the fourth bevel gear 907 is installed on the second transmission rod 401 for rotation, it does not directly drive the second transmission rod 401 to rotate. When the fourth bevel gear 907 rotates, the second transmission rod 401 is driven to rotate in the opposite direction through the direction adjustment component, thereby realizing the opposite rotation of the power wheels corresponding to the first transmission rod 4 and the second transmission rod 401.

[0044] The direction-adjusting member includes an annular groove provided on the back of the fourth bevel gear 907, a third gear 909 is rotatably mounted in the annular groove, the third gear 909 is meshed with a second gear ring 9011 provided in the annular groove, a first gear ring 9010 is coaxially fixed on the second transmission rod 401, the first gear ring 9010 is meshed with the third gear 909; The third gear 909 is rotatably connected to the mounting seat 6 ; a pull arm for supporting the second transmission rod 401 is integrated on the mounting seat 6 , and the third gear 909 is rotatably mounted on the pull arm.

[0045] In the embodiment of the present invention, when the fifth transmission rod 9 rotates, the third bevel gear 906 and the fourth bevel gear 907 are synchronously driven to rotate in the same direction through the first bevel gear 904. When the third bevel gear 906 rotates, the first transmission rod 4 is driven to rotate accordingly. When the fourth bevel gear 907 rotates, since the fourth bevel gear 907 is rotationally connected with the second transmission rod 401, the second transmission rod 401 is not directly driven to rotate. When the fourth bevel gear 907 rotates, the third gear 909 is driven to rotate through the second gear ring 9011. When the third gear 909 rotates, the first gear ring 9010 is driven to rotate in the opposite direction through meshing with the first gear ring 9010, so that the first transmission rod 4 and the second transmission rod 401 rotate in opposite directions, and the corresponding two driving wheels rotate in opposite directions. Among them, the transmission ratios between the No. 1 bevel gear 904 and the No. 3 bevel gear 906 and between the No. 3 bevel gear 906 and the No. 4 bevel gear 907 are adjusted according to actual production, so that the No. 1 bevel gear 904 drives the No. 1 transmission rod 4 and the No. 2 transmission rod 401 to have the same rotation speed when rotating. Therefore, the present invention does not specifically limit the transmission ratios between the No. 4 bevel gear 907 and the No. 3 bevel gear 906 and the No. 1 bevel gear 904, and the transmission ratio between the No. 2 bevel gear 905 and the two No. 5 bevel gears 908 is one to one.

[0046] The follower assembly includes a fourth transmission rod 803 rotatably mounted on the mounting seat 6, and the fourth transmission rod 803 is connected to the slider 302 via a synchronous driving member; A transmission shaft 804 perpendicular to the fourth transmission rod 803 is rotatably mounted at the bottom of the fourth transmission rod 803, and the sliding rod 903 and the transmission shaft 804 are connected via a bevel gear 805; A fourth bevel gear 907 is rotatably mounted at the bottom of the mounting seat 6 , and the rotating shaft of the fourth bevel gear 907 is connected to the transmission shaft 804 through a second transmission chain 806 . A plurality of transmission members 902 are equidistantly and coaxially fixed on the fifth transmission rod 9 , and the transmission members 902 are meshed with the second gear 807 .

[0047] In the embodiment of the present invention, when the two sliders 302 move relative to each other, that is, when the driving wheel is adjusted, the fourth transmission rod 803 is driven to rotate through the synchronous driving member, and when the fourth transmission rod 803 rotates, the transmission shaft 804 is driven to rotate through the bevel gear 805, and when the transmission shaft 804 rotates, the second gear 807 is driven to rotate through the second transmission chain 806, and when the second gear 807 rotates, the fifth transmission rod 9 is driven to move axially along the sliding rod 903 through engagement with the transmission member 902, so that when the second gear 807 rotates, the sliding of the fifth transmission rod 9 is driven to realize the engagement of the second bevel gear 905 with the two fifth bevel gears 908 or the engagement of the first bevel gear 904 with the fourth bevel gear 907 and the third bevel gear 906.

[0048] The synchronous driving member includes a transmission square cylinder 801 fixed to one side of the slider 302 facing the other slider 302, and a guide square tube 802 is slidably installed in the transmission square cylinder 801, and the guide square tube 802 is fixed to the other slider 302; A rack is provided at the bottom or top of the transmission square tube 801 , and the rack is meshed with the first gear 8 coaxially fixed on the fourth transmission rod 803 .

[0049] In the embodiment of the present invention, when the two sliders 302 move relative to each other, that is, when the driving wheel is adjusted, the transmission square tube 801 and the guide square tube 802 are driven to move relative to each other. When the transmission square tube 801 moves, the meshing of its rack portion with the first gear 8 drives the first gear 8 and the fourth transmission rod 803 to rotate; Among them, the advantage of this embodiment is that it switches the power distribution when adjusting the driving wheel through the adjustment component.
