[0032] Please refer to Figures 1 to 4 The utility model provides an assembly mechanism for assembling a rotating shaft of a balancing vehicle, which is used to assemble a first shaft body 1, a second shaft body 2 and a shaft sleeve 3, and includes a base 4, a first driving member 5, a second driving member 6 and a limit assembly;

[0033] The base 4 is tilted, and the base 4 includes a first placement area 401, a sleeve placement area 402, a second placement area 403, a first combination area 404, and a second combination area 405; the first placement area 401, the sleeve placement area 402, and the second placement area 403 are sequentially arranged side by side at one end of the top of the slope of the base 4; the first combination area 404 and the second combination area 405 are sequentially arranged at one end of the bottom of the slope of the base 4; the first placement area 401 and the sleeve placement area 402 are respectively connected to the first combination area 404; the first combination area 404 and the second placement area 403 are respectively connected to the second combination area 405; the first shaft body 1 is placed in the first placement area 401, the second shaft body 2 is placed in the second placement area 403, and the sleeve 3 is placed in the sleeve placement area 402;

[0034] The limiting assembly includes a connecting frame 71, a first blocking assembly 72 and a second blocking assembly 73; the connecting frame 71 is mounted above the first combination area 404 and the second combination area 405, and the first blocking assembly 72 and the second blocking assembly 73 are respectively arranged on the connecting frame 71; the first blocking assembly 72 is used to block the first shaft body 1 from entering the first combination area 404, and the second blocking assembly 73 is used to block the second shaft body 2 from entering the second combination area 405;

[0035] The first driving member 5 is arranged at the connection between the first placement area 401 and the first combination area 404, and is used to insert one end of the first shaft body 1 into the sleeve 3; the second driving member 6 is arranged at the connection between the first combination area 404 and the second combination area 405, and is used to sleeve the second shaft body 2 on the outer periphery of the sleeve 3.

[0036] The diameter of one end of the first shaft body 1 is relatively small. During assembly, the sleeve 3 is first sleeved on the end of the first shaft body 1 with a relatively small diameter, and then the second shaft body 2 is sleeved on the outer periphery of the sleeve 3 to obtain the parallel car rotating shaft. In addition, the base 4 is provided with two lifting plates of different thicknesses along the conveying direction. One end of the first lifting plate is located in the second placement area 403, and the other end of the first lifting plate passes through the first combination area 404 and the second combination area 405, and is connected to the bottom end of the slope of the base 4; one end of the second lifting plate is located in the sleeve placement area 402, and the other end of the second lifting plate passes through the first combination area 404 and the second combination area 405, and is connected to the bottom end of the slope of the base 4. The horizontal heights of the first shaft body 1, the second shaft body 2 and the sleeve 3 are adjusted respectively by the lifting plate, so that one end of the first shaft body 1 is adapted to the position of the sleeve 3, and the second shaft body 2 is adapted to the position of the sleeve 3, so that when the first shaft body 1 is translated toward the side of the sleeve 3, the sleeve 3 can be inserted into one end of the first shaft body 1, and when the second shaft body 2 is translated toward the side of the sleeve 3, the second shaft body 2 can be sleeved on the outer periphery of the sleeve 3.

[0037] The base 4 of the assembly mechanism is tilted, and the first shaft body 1, the second shaft body 2 and the sleeve 3 to be assembled above automatically slide to the first assembly area 404 under the action of gravity; in the first assembly area 404, the first drive member 5 assembles the first shaft body 1 and the sleeve 3, and then the first shaft body 1 with the sleeve 3 and the second shaft body 2 enter the second assembly area 405; in the second assembly area 405, the second drive member 6 assembles the second shaft body 2 and the sleeve 3, realizing automatic assembly, reducing manual participation, and improving the production efficiency of the shaft assembly. At the same time, the assembly force of the first drive member 5 and the second drive member 6 is constant, ensuring the uniformity of the shaft assembly and improving the installation accuracy.

[0038] The first blocking component 72 is disposed in the first assembly area 404, and the second blocking component 73 is disposed in the second assembly area 405. Before the first shaft body 1 and the sleeve 3 are assembled, the first blocking component 72 blocks the first shaft body 1 to be assembled above, preventing the first shaft body 1 to be assembled above from continuing to enter the first assembly area 404, and preventing the first shaft body 1 to be assembled above from pressing the first shaft body 1 below, causing the problem of positional misalignment of the first shaft body 1. Similarly, before the second shaft body 2 and the sleeve 3 are assembled, the second blocking component 73 blocks the second shaft body 2 to be assembled above, preventing the second shaft body 2 to be assembled above from continuing to enter the second assembly area 405, affecting the assembly of the second shaft body 2 and the sleeve 3.

[0039] Specifically, the limiting assembly further includes a shaft sleeve limiting assembly 74, and the shaft sleeve limiting assembly 74 is arranged on a side of the second blocking assembly 73 close to the bottom of the slope;

[0040] The shaft sleeve limiting assembly 74 includes a shaft sleeve limiting driving member 741 and a limiting plate 742; the shaft sleeve limiting driving member 741 is arranged on the connecting frame 71, and the driving end of the shaft sleeve limiting driving member 741 passes through the connecting frame 71 and is connected to the limiting plate 742; a plurality of avoidance notches are arranged at intervals at the bottom of the limiting plate 742; the shape of the avoidance notches is adapted to the first shaft body 1.

[0041] The sleeve limiting assembly 74 drives the limiting plate 742 to approach or move away from one end of the first shaft body 1. Before the second shaft body 2 is assembled with the sleeve, when the sleeve limiting assembly 74 drives the limiting plate 742 to approach one end of the first shaft body 1, it will be tightly against the side wall of one end of the first shaft body 1; then, the second driving member 6 pushes the second shaft body 2 so that the second shaft body 2 is sleeved on the outer periphery of the sleeve 3. At this time, the limiting plate 742 plays a limiting role, preventing the second shaft body 2 or the sleeve 3 from continuing to move toward the side of the first shaft body 1, avoiding the problem of the second shaft body 2 or the sleeve 3 being inserted too deep, and improving the assembly accuracy. After the second shaft body 2 and the sleeve are assembled, the sleeve limiting assembly 74 drives the limiting plate 742 away from one end of the first shaft body 1 to prevent the limiting plate 742 from interfering with the first shaft body 1 and being unable to move out of the second combination area 405.

[0042] Specifically, the base 4 is provided with a first baffle 41, a second baffle 42, a third baffle 43, a fourth baffle 44 and a fifth baffle 45; the first baffle 41 is arranged on the left side of the base 4, and the second baffle 42 is arranged on the right side of the base 4; the third baffle 43 and the fourth baffle 44 are arranged side by side between the first baffle 41 and the second baffle 42; the first baffle 41 and the third baffle 43 cooperate to form a first placement area 401, and the third baffle 43 and the fourth baffle 44 cooperate to form a sleeve placement area 402; the fourth baffle 44 and the second baffle 42 cooperate to form a second placement area 403; the fourth baffle 44 is longer than the third baffle 43, and the lower end of the fourth baffle 44 extends into the first combination area 404, and after the sleeve 3 enters the first combination area 404, one end of the sleeve 3 abuts against the fourth baffle 44;

[0043] The fifth baffle 45 is disposed in the second assembly area 405 and is located on the left side of the base 4 . The fifth baffle 45 corresponds to the position of the second driving member 6 . After the first shaft body 1 enters the second assembly area 405 , the other end of the first shaft body 1 abuts against the fifth baffle 45 .

[0044] The first baffle 41, the second baffle 42, the third baffle 43, and the fourth baffle 44 act as partitions, thereby forming a first placement area 401, a sleeve placement area 402, and a second placement area 403 on the base 4; at the same time, they also have a limiting function, and the two ends of the first shaft body 1 move along the side walls of the first baffle 41 and the third baffle 43 respectively, while the two ends of the second shaft body 2 move along the side walls of the second baffle 42 and the fourth baffle 44 respectively, and the two ends of the sleeve 3 move along the side walls of the third baffle 43 and the fourth baffle 44 respectively, thereby preventing the first shaft body 1, the second shaft body 2, and the sleeve 3 from shifting when moving downward, avoiding the problem that the first shaft body 1, the second shaft body 2 or the sleeve 3 are misaligned and cannot be combined during installation, thereby improving the accuracy of assembly.

[0045] Specifically, the first blocking assembly 72 and the second blocking assembly 73 have the same structure, both comprising a blocking cylinder 701 and a baffle 702 ; the blocking cylinder 701 is disposed on a connecting frame 71 , and a driving end of the blocking cylinder 701 passes through the connecting frame 71 and is connected to the baffle 702 .

[0046] With the above structure, the blocking cylinder 701 drives the baffle 702 to move closer to or away from the base 4, so as to be inserted between the adjacent first shaft body 1 / second shaft body 2, thereby blocking the first shaft body 1 from continuing to enter the first combination area 404, or the second blocking component 73 is used to block the second shaft body 2 from continuing to enter the second combination area 405.

[0047] Specifically, the first driving member 5 and the second driving member 6 have the same structure, and both include a driving cylinder 601 and a top plate 602 ; the driving cylinder 601 is disposed on the base 4 , and the driving end of the driving cylinder 601 is connected to the top plate 602 .

[0048] In a specific embodiment of the utility model, the first driving member 5 and the second driving member 6 both include a driving cylinder 601 and a top plate 602. The first driving member 5 drives the top plate 602 to approach the other end of the first shaft body 1 through the driving cylinder 601, and then the top plate 602 pushes the first shaft body 1 to move toward the sleeve 3. Since one end of the sleeve 3 abuts against the fourth baffle 44, one end of the first shaft body 1 is inserted into the sleeve 3 through the cooperation of the top plate 602 and the fourth baffle 44.

[0049] Similarly, the second driving member 6 drives the top plate 602 to approach one end of the second shaft body 2 by driving the cylinder 601, and then the top plate 602 pushes the second shaft body 2 to move toward the sleeve 3. Since the other end of the first shaft body 1 is against the fifth baffle 45, the other end of the second shaft body 2 is sleeved on the outer periphery of the sleeve 3 through the cooperation of the top plate 602 and the fifth baffle 45.

[0050] Specifically, the inclination angle of the base 4 is 25 to 45 degrees. In a specific embodiment of the utility model, the inclination angle of the base 4 is 25 to 45 degrees. With the inclination angle in the above range, gravity can be used to move the first shaft body 1, the second shaft body 2, the shaft sleeve 3 and the assembled rotating shaft along the inclination direction, so that the first shaft body 1, the second shaft body 2, the shaft sleeve 3 automatically enter the first combination area 404 and the rotating shaft automatically moves out of the second combination area 405.

[0051] Optionally, a receiving platform 8 is further included, and the receiving platform 8 is arranged at one end of the bottom of the slope of the base 4. The receiving platform 8 is used to collect the assembled shaft; since the base 4 is arranged at an angle, after the shaft is assembled, it directly rolls from the base 4 to the receiving platform 8, which is convenient for the staff to collect the shaft.

[0052] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
