DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, a preferred embodiment of a sidecar frame with an adjustable rocker arm according to the present invention includes a sidecar frame 1, a first connecting arm 21, a second connecting arm 31, a connecting shaft 4, a rocker arm 5, and an adjustment mechanism 6. The sidecar frame 1 is used to mount a sidecar. The first and second connecting arms 21, 31 are welded and fixed to the sidecar frame 1 at intervals. The first end of the connecting shaft 4 is movably connected to the first connecting arm 21, and the second end of the connecting shaft 4 is slidably mounted on the second connecting arm 31. The second end of the connecting shaft 4 is also connected to the adjustment mechanism 6, allowing the first end of the connecting shaft 4 to rotate about the connection point between the first end of the connecting shaft 4 and the first connecting arm 21. The rocker arm 5 is mounted on the connecting shaft 4 and is used to mount a sidecar wheel. The adjustment mechanism 6 is used to adjust the position of the second end of the connecting shaft 4, thereby changing the deflection angle of the connecting shaft 4 in the horizontal plane, thereby driving the rocker arm 5 to deflect, so that the sidecar wheel mounted on the rocker arm 5 is parallel to the rear wheel.

[0029] like Figure 3 and Figure 4 As shown, the connecting shaft 4 includes a first shaft 41 and a second shaft 42. The second shaft 42 is movably inserted into the first shaft 41 and can slide axially along the first shaft 41, thereby changing the length of the second shaft 42 inserted into the first shaft 41, thereby changing the length of the connecting shaft 4 to accommodate the angular adjustment of the connecting shaft 4. The first shaft 41 is provided with an axially arranged receiving hole 411, and the second shaft 42 is inserted into the receiving hole 411. The first shaft 41 is movably connected to the first connecting arm 21 at the end away from the second shaft 42, and the first shaft 41 is able to rotate relative to the first connecting arm 21 in the horizontal plane. The second shaft 42 is connected to the adjustment mechanism 6 at the end away from the first shaft 41, and the second shaft 42 is able to rotate relative to the adjustment mechanism 6 in the horizontal plane. The two ends of the connecting shaft 4 are movably connected to the first connecting arm 21 and the second connecting arm 31 respectively, and the length of the connecting shaft 4 can be changed. Therefore, when the adjusting mechanism 6 changes its position, the connecting shaft 4 can automatically adjust its angle and length to adapt to the position of the adjusting mechanism 6, thereby adjusting the deflection angle of the connecting shaft 4 and finally adjusting the deflection angle of the rocker arm 5.

[0030] like Figure 3 、 Figure 5 and Figure 6As shown, the first connecting arm 21 is provided with a first receiving groove 211 and a first cover plate 22. The first receiving groove 211 is hemispherical, and the first cover plate 22 is provided with a second receiving groove 221 that cooperates with the first receiving groove 211. The first cover plate 22 is detachably fixed to the first connecting arm 21. The first receiving groove 211 and the second receiving groove 221 are combined to form a receiving space. The first shaft rod 41 is provided with a first ball head 43 at the end away from the second shaft rod 42. The first ball head 43 of the first shaft rod 41 is disposed in the first receiving space 71, and the first cover plate 22 fixes the ball head in the first receiving space 71. The first cover plate 22 is also provided with a first through-hole 222 that communicates with the second receiving groove 221. The first through-hole 222 is used to allow the first shaft rod 41 of the connecting shaft 4 to pass through the first receiving space 71 to facilitate connection with the second shaft rod 42. The diameter of the first through-hole 222 is larger than that of the first shaft 41, ensuring that the first shaft 41 has room to rotate. The outer diameter of the first through-hole 222 is larger than the inner diameter, thereby increasing the range of rotation of the first shaft 41. The outer end of the first through-hole 222 is the end away from the first connecting arm 21, while the inner end of the first through-hole 222 is the end closer to the first connecting arm 21. The first connecting arm 21 and the first cover plate 22 are typically fixed with screws, which is simple and convenient. A removable connection facilitates the assembly of the ball head of the first shaft 41 into the first accommodating space 71. The first ball head 43 has a first top surface 431 and a first bottom surface 432. The second accommodating groove 221 has two first limiting surfaces 223 that adapt to the first top surface 431 and the first bottom surface 432. The two limiting surfaces cooperate with the first top surface 431 and the first bottom surface 432, respectively, to prevent the first shaft 41 from rotating, thereby limiting the rotation of the connecting shaft 4.

[0031] The second connecting arm 31 is provided with a scale (not shown in the figure), and the scale is used to display the deflection angle of the connecting shaft 4.

[0032] like Figure 3 、 Figure 7 and Figure 8As shown, the adjustment mechanism 6 includes a fastener 61 and an adjustment seat 62. The adjustment seat 62 is slidably mounted on the second connecting arm 31, and the fastener 61 is screwed onto the adjustment seat 62. The adjustment seat 62 is used to be movably connected to the second shaft 42 of the connecting shaft 4; rotating the fastener 61 can fasten the adjustment seat 62 to the second connecting arm 31 or loosen the adjustment seat 62 to facilitate sliding on the second connecting arm 31; when the fastener 61 is rotated to abut against the second connecting arm 31, the adjustment seat 62 is fixed on the second connecting arm 31, that is, the position of the adjustment seat 62 and the second connecting arm 31 is relatively fixed; when the fastener 61 is rotated to separate from the second connecting arm 31, the adjustment seat 62 is loosened, that is, the adjustment seat 62 can slide on the second connecting arm 31, thereby changing the position of the adjustment seat 62. The fastener 61 is usually a bolt, using existing parts to reduce costs. When the position of the adjusting seat 62 needs to be adjusted, first loosen the fastener 61, and then adjust the position of the adjusting seat 62. After adjusting to the right position, tighten the fastener 61 again. In other embodiments, two fasteners 61 can also be provided to ensure that the adjusting seat 62 is not easy to loosen.

[0033] The adjustment seat 62 includes a seat body 621 and a second cover plate 622. The seat body 621 is provided with a third receiving groove 6211, which is hemispherical. The second cover plate 622 is provided with a fourth receiving groove 6221 that matches the third receiving groove 6211. The second cover plate 622 is detachably fixed to the seat body 621, so that the third receiving groove 6211 and the fourth receiving groove 6221 are combined to form a second receiving space 72. The second shaft rod 42 is provided with a second ball head 44 at the end away from the first shaft rod 41. The second ball head 44 on the second shaft rod 42 is located in the second receiving space 72, and the second cover plate 622 fixes the ball head in the second receiving space 72. The second cover plate 622 is also provided with a second through-hole 6222 that is connected to the fourth receiving groove. The second through-hole 6222 is used to allow the second shaft rod 42 to pass through the second receiving space 72 to facilitate connection with the first shaft rod 41. The diameter of the second through-hole 6222 is larger than that of the second shaft 42, ensuring that the second shaft 42 has room to rotate. The outer diameter of the second through-hole 6222 is larger than the inner diameter, thereby increasing the range of rotation of the second shaft 42. The outer end of the second through-hole 6222 is the end away from the second connecting arm 31, while the inner end of the through-hole of the second shaft 42 is the end closer to the second connecting arm 31. The base 621 and the second cover plate 622 are typically fixed with screws, which is simple and convenient. A removable connection facilitates the assembly of the ball portion of the second shaft 42 into the second accommodating space 72. The second ball head 44 has a second top surface 441 and a second bottom surface 442. The fourth accommodating groove 6221 has two second limiting surfaces 6223 that adapt to the second top surface 441 and the second bottom surface 442. The two limiting surfaces respectively cooperate with the second top surface 441 and the second bottom surface 442 to prevent the second shaft 42 from rotating, thereby limiting the rotation of the connecting shaft 4.

[0034] When assembling the connecting shaft 4 and the adjusting mechanism 6, first install the rocker arm 5 on the first shaft rod 41, then insert the end of the first shaft rod 41 away from the first ball head 43 into the first through-hole 222, then place the first ball head 43 in the first receiving groove 211, and then fix the first cover plate 22 to complete the fixation of the first shaft rod 41; then put the seat body 621 on the second connecting arm 31, and then insert the second shaft rod 42 from the end away from the second ball head 44 into the second through-hole 6222, and at the same time insert it into the first shaft rod 41, and then fix the second cover plate 622 to fix the second shaft rod 42, thereby completing the assembly of the connecting shaft 4 with the first connecting arm 21 and the adjusting mechanism 6.

[0035] like Figure 9 and Figure 10As shown, when adjustment is required, first loosen the fastener 61, then slide the seat 621, allowing the seat 621 to drive the second shaft 42 to move and simultaneously drive the first shaft 41 to deflect, thereby driving the rocker arm 5 to deflect. In this way, the deflection angle of the side wheel can be adjusted, and the error formed after the side frame 1 is assembled with the frame can be eliminated. After the adjustment is in place, tighten the fastener 61, and the adjustment is convenient and quick. The first shaft 41 and the second shaft 42 are connected to the first connecting arm 21 and the adjustment seat 62 via the first ball head 43 and the second ball head 44, respectively. The connection between the first shaft 41 and the first connecting arm 21 is set to a spherical shape, and the connection between the second shaft 42 and the adjustment seat 62 is set to a spherical shape. This ensures that they always fit together, ensuring that they are not easily loosened during use, thereby not affecting the deflection angle of the connecting shaft 4. At the same time, the area of contact between the first ball head 43 and the second ball head 44 and the corresponding first connecting arm 21 and the adjustment seat 62 is almost unchanged before and after adjustment, and the force is not concentrated at a single point, thereby extending the service life.

[0036] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's description and drawings, directly or indirectly applied to other related technical fields, is also within the patent protection scope of the present invention.
