[0043] 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.

[0044] The invention provides an automatic guiding and locking device for a carriage and a chassis.

[0045] First embodiment:

[0046] Please combine Figures 1 to 5 , Figures 8 to 10 , an automatic guiding and locking device for a carriage and chassis, comprising a chassis longitudinal beam 1, a carriage frame assembly 2 and a locking assembly 6;

[0047] The outer wall of the chassis longitudinal beam 1 is fixedly provided with a front gear frame 3, the carriage frame assembly 2 includes a mounting frame 21 located above the chassis longitudinal beam 1, the inner wall of the mounting frame 21 is installed with a first guide wheel 22, a second guide wheel 23, a third guide wheel 24 and a fourth guide wheel 25, two clamping plates 26 are fixedly provided on the lower surface of the mounting frame 21 and located between the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25, and side plates 27 are fixedly provided on the lower surface of the mounting frame 21 and located on one side of the two clamping plates 26;

[0048] Mounting plates 4 are installed on both sides of the chassis longitudinal beam 1 by bolts, and positioning components 5 are installed on the top of the two mounting plates 4. The positioning components 5 include a cast iron seat 51 fixed on the upper surface of the mounting plate 4, and two inclined plates 53 are fixed on the top of the cast iron seat 51;

[0049] See also Figure 1 and Figure 2 : Before locking, the car frame assembly 2 needs to be lowered along the vertical direction of the chassis longitudinal beam 1, and during the downward lowering process, the front end of the car frame assembly 2 will not exceed the front limit position of the chassis longitudinal beam 1 due to the obstruction of the front gear frame 3.

[0050] See also Figure 2 , Figure 3and Figure 5 : When the mounting frame 21 is close to the uppermost positioning assembly 5 of the chassis longitudinal beam 1, the first guide wheel 22 and the second guide wheel 23 will be close to the positioning assembly 5 on the right side of the chassis longitudinal beam 1, and the third guide wheel 24 and the fourth guide wheel 25 will be close to the positioning assembly 5 on the left side of the chassis longitudinal beam 1;

[0051] When the mounting frame 21 and the chassis longitudinal beam 1 deviate to the left, the first guide wheel 22 and the third guide wheel 24 will roll on the corresponding inclined plate 53;

[0052] When the mounting frame 21 and the chassis longitudinal beam 1 deviate to the right, the second guide wheel 23 and the fourth guide wheel 25 will roll on the corresponding inclined plate 53;

[0053] Therefore, no matter the car frame assembly 2 and the chassis longitudinal beam 1 are biased to the left or right, the evenly corresponding inclined plates 53 support the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 to ensure the balance of the car frame assembly 2, and finally the mounting frame 21 is moved to the center position of the chassis longitudinal beam 1 through the rolling of the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25, thereby realizing the automatic guiding function.

[0054] A support plate 8 is fixedly provided on the side wall of the mounting plate 4, an electric cylinder 10 is installed on the outer wall of the support plate 8, a push rod 11 is installed on the output end of the electric cylinder 10, four positioning grooves 13 are provided on the front end of the push rod 11, and extension plates 14 are slidably connected inside the four positioning grooves 13, a second key rod 15 is slidably connected at the front end axis of the push rod 11, a tapered rod 16 is fixedly provided at the left end of the second key rod 15 and located inside the push rod 11, and a trigger plate 17 is fixedly provided at the right end of the second key rod 15;

[0055] The locking assembly 6 includes a locking plate 61 fixedly mounted on the upper surface of the mounting plate 4 , a clamping sleeve 62 is fixedly mounted on the outer wall of the locking plate 61 , and a sliding column 63 is slidably connected to the interior of the clamping sleeve 62 .

[0056] See also Figure 1 , Figure 5 and Figure 8 : When the car frame assembly 2 and the chassis longitudinal beam 1 are corrected, the user can start the electric cylinder 10 to push the push rod 11 to lock. During the locking process, the push rod 11 moves inside the positioning assembly 5 and finally moves to the inside of the lock plate 61. After that, it is pushed by the slide column 63 in the sleeve 62. During the pushing process, it is subjected to the reaction force of the slide column 63. The trigger plate 17 pushes the second key rod 15 in the opposite direction to control the tapered rod 16 to slide to the left. During the sliding process, the four extension plates 14 will follow the conical surface movement of the tapered rod 16 and rise and extend along the vertical direction of the positioning groove 13. The extended extension plates 14 can be stably stressed with the inner wall of the lock plate 61.

[0057] The relative distances between the first guide wheel 22 and the second guide wheel 23 are equal, and the relative distances between the third guide wheel 24 and the fourth guide wheel 25 are equal. The outer walls of the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 are all triangular structures with a high middle and low sides.

[0058] The inclined plate 53 is in an inverted triangle shape with a middle bottom and high sides. The four extension plates 14 are equidistantly distributed in a ring shape about the axis of the conical rod 16 , and the lower surfaces of the four extension plates 14 are in contact with the outer wall of the conical rod 16 .

[0059] It can be understood that when the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 roll on the inclined plate 53, the triangular structures that adapt to each other can make the rolling more stable and can automatically correct the position.

[0060] In this embodiment: the assembly of the car body and the chassis is guided and limited along the vertical direction of the chassis longitudinal beam 1 to avoid deviation in the direction of the chassis longitudinal beam 1. For example, when the mounting frame 21 and the chassis longitudinal beam 1 are not in contact and there is a deviation, the mounting frame 21 can be automatically guided so that the car body can be assembled with the frame more accurately, ensuring that no matter the mounting frame 21 deviates to the left or to the right, it can be automatically guided and corrected to move to the middle position. Secondly, in the locking process, the tapered rod 16 is used to move in the reverse direction to realize the rise of the four extension plates 14 and at the same time stabilize the force on the lock plate 61, ensuring that the push rod 11 can be concentric with the hole of the lock plate 61. Such a design can ensure that the push rod 11 and the lock plate 61 are locked more stably and closely.

[0061] Second embodiment:

[0062] See also Figure 1 , Figures 5 to 7 An insulating plate 52 is fixedly provided in the middle position of the cast iron seat 51, and a positive pole magnetic sleeve 54 and a negative pole magnetic sleeve 55 are penetrated in the middle position of the insulating plate 52. A limit plate 9 is installed on the side wall of the mounting plate 4 and located above the support plate 8 by bolts. A sealing plate 56 is rotatably connected inside the limit plate 9, and a spiral edge 12 is provided on the outer wall of the push rod 11.

[0063] See also Figure 5 and Figure 6 : During the working process of the first embodiment, before the carriage frame assembly 2 and the chassis longitudinal beam 1 are calibrated, the user needs to first control the electric cylinder 10 to withdraw the push rod 11 to the left end, and a gap needs to be left between the cast iron seat 51 and the lock plate 61 to ensure the passage of the card plate 26;

[0064] During the movement of the push rod 11 , the spiral edge 12 will be synchronously driven to move in the sealing plate 56 . The horizontal movement of the spiral edge 12 will drive the sealing plate 56 to rotate horizontally. The sealing plate 56 will synchronously drive the positive magnetic sleeve 54 and the negative magnetic sleeve 55 to rotate.

[0065] See also Figure 7 (a) in the figure: In the initial state, the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 are arranged horizontally. Due to the arrangement of the insulating plate 52, the magnetic lines of force generated by the positive pole magnetic sleeve 54 will enter into the cast iron seat 51 and be attracted by the negative pole magnetic sleeve 55. Finally, the magnetic lines of force will not expand outward and the cast iron seat 51 will have no magnetic force.

[0066] See also Figure 7 (b) in the figure: when the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 rotate 90 degrees, the magnetic force lines of the positive pole magnetic sleeve 54 will expand outwards and then be attracted by the negative pole magnetic sleeve 55, so that the cast iron seat 51 generates magnetic force.

[0067] See also Figure 1 : When the cast iron seat 51 generates magnetic force, the inclined plate 53 will also generate magnetic force. In this way, when the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 contact the corresponding inclined plate 53, the generated magnetic force can attract the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 to the corresponding inclined plate 53.

[0068] The spiral edge 12 and the sealing plate 56 are connected by thread engagement, and the sealing plate 56, the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 are fixedly connected.

[0069] The push rod 11 passes through the inside of the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 and does not contact the inner wall of the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 .

[0070] It can be understood that the spiral edge 12 is only connected to the sealing plate 56 , so that during the horizontal movement of the push rod 11 , the push rod 11 and the spiral edge 12 will not affect the positive pole magnetic sleeve 54 and the negative pole magnetic sleeve 55 .

[0071] In this embodiment: on the basis of the guidance of the inclined plate 53, a cast iron seat 51 that can generate magnetic force is also provided, and the cast iron seat 51 transmits the magnetic force to the inclined plate 53, so that when the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 contact the inclined plate 53 containing magnetic force, they can be attracted by magnetic force, which can further ensure the stability of the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 during rolling, and avoid wheel position deviation during rolling. Secondly, the generation and disappearance of the magnetic force are realized in a linkage manner during the locking process, so this design is also convenient for users to operate.

[0072] Third embodiment:

[0073] See also Figure 1 , Figure 8 and Fig.11 , further comprising a stabilizing component 7;

[0074] A slide groove 64 is formed inside the slide post 63, and a limit block 65 adapted to the slide groove 64 is fixedly disposed on the inner wall of the ferrule 62;

[0075] The stabilizing component 7 includes a first bracket 71 and a second bracket 72 fixed on the outer wall of the locking plate 61, and a first key rod 74 is slidably connected inside the first bracket 71 and the second bracket 72. A baffle 77 is fixed on the outer wall of the first key rod 74, and a return spring 73 is sleeved on the outer wall of the first key rod 74 and on the opposite side of the second bracket 72 and the baffle 77. A guide wheel 75 is installed on the left end of the first key rod 74, and a stabilizing plate 76 is fixed on the right end of the first key rod 74.

[0076] See also Figure 8 and Fig.11 : During the operation of the first embodiment, the trigger plate 17 pushes the slide column 63 forward during the movement inside the sleeve 62, and the slide column 63 will drive the conical structure at its front end forward during the movement. At this time, the guide wheel 75 will follow the conical structure to make the first key rod 74 slide horizontally inside the first bracket 71 and the second bracket 72, and during the sliding process, the baffle 77 will control the return spring 73 to be compressed, and the stabilizing plate 76 will follow the sliding of the first key rod 74 into the inside of the side plate 27.

[0077] One end of the return spring 73 is fixedly connected to the baffle 77 , the front end of the slide post 63 is in a conical structure, and the outer wall of the guide wheel 75 and the front end of the slide post 63 are in contact with each other.

[0078] This embodiment: On the basis of the locking of the first embodiment, an independent stabilizing component 7 is also designed, and the guide wheel 75 automatically generates horizontal movement following the movement of the push rod 11, and the horizontal movement simultaneously drives the stabilizing plate 76 to be inserted into the side plate 27. Such a design is equivalent to adding a reinforcing rib design on the basis of the insertion of the locking plate 61. Even if the upper mounting frame 21 is under high load-bearing capacity and high shaking force, the two locking designs can ensure that the chassis longitudinal beam 1 and the mounting frame 21 have strong load-bearing capacity and resistance.

[0079] Please refer to Figures 1 to 11 The working principle of the automatic guiding and locking device for a carriage and chassis provided by the present invention is as follows:

[0080] Step S1: Before calibrating the carriage frame assembly 2 and the chassis longitudinal beam 1, the user needs to control the electric cylinder 10 to move the push rod 11 to the left end, and leave a gap between the cast iron seat 51 and the lock plate 61 to ensure the passage of the card plate 26. During the movement, the push rod 11 will synchronously drive the spiral edge 12 to move in the sealing plate 56. The horizontal movement of the spiral edge 12 will drive the sealing plate 56 to rotate horizontally. The sealing plate 56 will synchronously drive the positive magnetic sleeve 54 and the negative magnetic sleeve 55 to rotate. As the positive magnetic sleeve 54 and the negative magnetic sleeve When the cast iron base 51 rotates 90 degrees, the magnetic force lines of the positive pole magnetic sleeve 54 will expand outwards, and then be attracted by the negative pole magnetic sleeve 55, so that the cast iron base 51 generates magnetic force at this time. When the cast iron base 51 generates magnetic force, the inclined plate 53 will also generate magnetic force. In this way, when the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 contact the corresponding inclined plate 53, the generated magnetic force can attract the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 to the corresponding inclined plate 53;

[0081] Step S2: When the mounting frame 21 is close to the uppermost positioning assembly 5 of the chassis longitudinal beam 1, the first guide wheel 22 and the second guide wheel 23 will be close to the positioning assembly 5 on the right side of the chassis longitudinal beam 1, and the third guide wheel 24 and the fourth guide wheel 25 will be close to the positioning assembly 5 on the left side of the chassis longitudinal beam 1;

[0082] When the mounting frame 21 and the chassis longitudinal beam 1 deviate to the left, the first guide wheel 22 and the third guide wheel 24 will roll on the corresponding inclined plate 53;

[0083] When the mounting frame 21 and the chassis longitudinal beam 1 deviate to the right, the second guide wheel 23 and the fourth guide wheel 25 will roll on the corresponding inclined plate 53;

[0084] Therefore, no matter the carriage frame assembly 2 and the chassis longitudinal beam 1 are biased to the left or right, the evenly corresponding inclined plates 53 support the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 to ensure the balance of the carriage frame assembly 2, and finally the mounting frame 21 is moved to the center position of the chassis longitudinal beam 1 by the rolling of the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25;

[0085] The clamping plate 26 is automatically guided by the first guide wheel 22, the second guide wheel 23, the third guide wheel 24 and the fourth guide wheel 25 to achieve concentric overlap between the hole in the clamping plate 26 and the hole in the locking plate 61, so that the user can push the push rod 11 into the overlapping hole of the clamping plate 26 and the locking plate 61 to achieve the locking of the clamping plate 26 and the locking plate 61, so that the entire mounting frame 21 is also installed with the chassis longitudinal beam 1;

[0086] Step S3: During the working process of step S1, the trigger plate 17 pushes the slide column 63 forward while moving inside the sleeve 62. The slide column 63 will drive the conical structure at its front end forward during the moving process. At this time, the guide wheel 75 will follow the conical structure to make the first key rod 74 slide horizontally inside the first bracket 71 and the second bracket 72, and during the sliding process, the baffle 77 will control the return spring 73 to be compressed, and the stabilizing plate 76 will follow the sliding of the first key rod 74 to enter the inside of the side plate 27 for secondary stabilization.

[0087] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
