DETAILED DESCRIPTION

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0028] To address the deficiencies or one of the deficiencies in the foregoing background art, the embodiments of the present application provide a support adjustable chassis spreader and a chassis spreader switching station, which can meet mixed flow production of multiple platforms and multiple vehicle models, and improve the mixed flow adaptation capability of the spreader.

[0029] Referring to Figures 1 to 5 The first aspect of the embodiments of the present application provides a support adjustable chassis spreader, which comprises: a hanger 100; a front support mechanism 10, which comprises a positioning seat 11 fixed on the hanger 100, and a positioning pin rotating seat 12 in clamping cooperation with the positioning seat 11, and the positioning seat 11 is provided with an elastic reset member 13 for resetting the positioning pin rotating seat 12 to be clamped to the positioning seat 11; a rear support mechanism 20, which comprises a guide shaft 21 arranged on the hanger 100, and a support seat 22 in sliding and rotating connection with the guide shaft 21, and the support seat 22 and the hanger 100 are provided with a positioning structure, and the support seat 22 is combined or separated from the positioning structure by rotating around the guide shaft 21.

[0030] The chassis lifting appliance of the embodiment of the application realizes the quick switching and automatic resetting functions of the positioning pin through the linkage design of the elastic resetting member 13 of the front support mechanism 10 and the positioning pin rotating seat 12.

[0031] When the positioning pin rotating seat 12 rotates to switch the position, the elastic resetting member 13 drives the positioning pin rotating seat 12 to automatically reset to the clamping position through preset deformation energy storage, so that the positioning pin switching operation can be quickly completed and high positioning accuracy is maintained.

[0032] The rear support mechanism 20 realizes the positioning adjustment of the support seat 22 on the lifting frame 100 through the overturning action of the support seat 22 around the guide shaft 21 and the sliding adjustment function. When the support seat 22 overturns, the positioning structure is released, and after the sliding adjustment position along the guide shaft 21, the support seat 22 is overturned and reset to the position, so that the position adjustment of the support seat 22 is realized.

[0033] The design realizes the modular positioning switching, so that the lifting appliance can simultaneously adapt to the chassis installation requirements of traditional fuel vehicle models and new energy vehicle models, meets the quick switching efficiency of 30 seconds per vehicle in multi-platform mixed production, and improves 50% compared with the traditional lifting appliance.

[0034] For example, the elastic resetting member 13 can adopt an elastic telescopic rod, one end of which is fixed in the positioning seat 11, and the other end is rotationally connected with the positioning pin rotating seat 12 through a bearing, and the telescopic stroke is not less than the distance required for the mutual disengagement of the positioning pin rotating seat 12 and the positioning seat 11.

[0035] The positioning pin rotating seat 12 and the positioning seat 11 are provided with a convex groove structure that can be rotationally and dislocatedly clamped. The guide shaft 21 adopts a cylindrical shaft, and the two ends are fixed on the lifting frame 100 through a connecting seat, and the support seat 22 is installed with a sliding block at the bottom to form a rotating pair with the guide shaft 21.

[0036] The positioning structure can adopt a magnetic attraction type positioning, and a magnet and an iron clamping block are matched, when the support seat 22 is overturned and inclined, the magnet and the iron clamping block are physically disengaged, and when the support seat 22 is overturned and reset to the horizontal plane, the magnet and the clamping block are attracted to realize the positioning.

[0037] In some optional embodiments, the first aspect is as follows: Figures 1 to 5 As shown in the figure, the embodiment of the application provides a support adjustable chassis lifting appliance, at least two positioning pins are circumferentially arranged on the positioning pin rotating seat 12 of the support adjustable chassis lifting appliance, the positioning pin rotating seat 12 is switched to the upward positioning pin by rotating around a horizontal shaft, and the positioning pin rotating seat 12 and the positioning seat 11 are provided with circumferentially uniformly distributed clamping structures 14.

[0038] The positioning pin rotating seat 12 of the embodiment of the present application realizes quick switching of positioning pins of multiple specifications through the circumferentially uniformly distributed clamping structures 14, and four groups of positioning pins correspond to mounting reference hole positions of different vehicle models, and when switching, the clamping constraint is released through a pulling action, and the positioning pin rotating seat 12 is automatically reset after rotating by a multiple of 90°.

[0039] The clamping structure 14 adopts a matching design of a protrusion and a groove, so as to ensure that the contact surface pressure of the positioning pin rotating seat 12 is uniformly distributed when the positioning pin rotating seat 12 is positioned at any angle, and to eliminate the positioning deviation caused by the difference between vehicle models due to the traditional single positioning pin structure.

[0040] The design enables the lifting appliance to complete the positioning switching of four vehicle models within 30 seconds, and the positioning repeatability reaches the sub-millimeter level, which is 80% more efficient than the traditional mechanical lock structure.

[0041] For example, the positioning pin rotating seat 12 is coaxially arranged with the positioning seat 11, the clamping structure 14 includes four protrusions uniformly distributed at the end of the positioning pin rotating seat 12, and the clamping structure 14 includes four grooves corresponding to the end of the positioning seat 11 to form a clamping matching.

[0042] The clamping structure 14 can be clamped and matched with each other when rotated by a multiple of 90°. The positioning pins on the positioning pin rotating seat 12 are of different diameters or are arranged at different positions to form different positioning specifications, so as to meet the mounting requirements of chassis of different vehicle models.

[0043] When switching the chassis of a new energy vehicle model, an operator first pulls the positioning pin rotating seat 12 to make the protrusions disengage from the grooves, releases the positioning pin rotating seat 12 after rotating to a target angle, and the protrusions are automatically embedded in the grooves under the action of the elastic reset member 13, thereby completing the switching of the positioning pins.

[0044] It should be noted that the chassis lifting appliance of the present application can meet the requirements of positioning pins of different shapes and sizes, realize the position switching of the positioning pins in XYZ directions (three directions of the chassis lifting appliance), and meet the spatial positioning adaptation requirements of different vehicle models.

[0045] In the first aspect, in some optional embodiments, referring to Figures 1 to 5 The positioning structure of the adjustable chassis lifting appliance provided in the embodiment of the present application includes a first positioning part 23 arranged on a lifting frame 100 and a second positioning part 24 arranged on a support seat 22, and the first positioning part 23 and the second positioning part 24 are matched through mechanical fitting or magnetic attraction, so as to limit the relative movement between the support seat 22 and the lifting frame 100.

[0046] The positioning structure of the present application realizes quick locking and releasing between the support seat 22 and the lifting frame 100 through reversible matching of mechanical fitting or magnetic attraction.

[0047] When the first positioning part 23 and the second positioning part 24 complete clamping or adsorption, the support seat 22 can be positioned on the hanger 100 to meet the support requirement. In the mixed production scene of new energy vehicle models and traditional vehicle models, the positioning structure cooperates with the sliding adjustment function of the support seat 22, which can significantly improve the switching efficiency of the chassis installation reference point and reduce the repeated positioning error.

[0048] In some optional embodiments of the first aspect, referring to Figures 1 to 5 As shown in the figure, the embodiments of the present application provide a support adjustable chassis lifting appliance, the first positioning part 23 is a long rack, the second positioning part 24 is a short rack, the support seat 22 is connected to the short rack through a sliding block, and the short rack is kept in engagement with the long rack through gravity.

[0049] The long rack and short rack engagement structure of the embodiments of the present application realizes the positioning of the support seat 22 through gravity self-locking. The long rack is fixed on the hanger 100, and the short rack is rigidly connected to the support seat 22 through a sliding block. When the support seat 22 is in a horizontal state, the short rack is naturally embedded into the long rack tooth groove under the action of gravity.

[0050] When the support seat 22 is tilted, the short rack is disengaged from the long rack, the positioning constraint is released, and the support seat 22 can be slidably adjusted to a target position along the guide shaft 21. After the support seat 22 is released, the support seat 22 automatically recovers to a horizontal state through gravity in the resetting process, so that the short rack precisely engages with the long rack, and the positioning repeated accuracy is high.

[0051] For example, the long rack is fixedly installed on the hanger 100 through a countersunk screw, and the length direction is consistent with the axis direction of the guide shaft 21. The short rack and the sliding block are fixed through a countersunk screw, and the tooth shape is completely matched with the long rack.

[0052] The guide shaft 21 is a cylindrical shaft, and both ends are fixed on the hanger 100 through a connecting seat. The sliding block and the guide shaft 21 form a rotary pair, and the long rack and the short rack are engaged and self-locked through gravity to maintain the horizontal position of the support seat 22.

[0053] When the new energy vehicle model chassis is switched, after the support seat 22 is slid along the guide shaft 21 to switch the position, the support seat 22 is released, the support seat 22 drives the short rack to automatically engage with the long rack under the action of gravity, and the whole positioning switching process can be completed within 20 seconds, and the positioning accuracy is improved by 2 times compared with the traditional structure.

[0055] The embodiment of the present application realizes the automatic reset function of the positioning pin rotating seat 12 through the cooperation of the spring and the limiting rod 15.

[0056] The limiting rod 15 includes a cylindrical segment and a circular block fixedly connected at both ends of the cylindrical segment, the spring is sleeved on the cylindrical segment, the cylindrical segment is in sliding fit with the small-diameter segment of the stepped groove on the positioning seat 11, the circular block at one end is in sliding fit with the large-diameter segment of the stepped groove on the positioning seat 11, and the circular block at the other end is in rotating fit with the stepped groove on the positioning pin rotating seat 12.

[0057] When an external force is applied to pull the positioning pin rotating seat 12, the limiting rod 15 slides outward along the stepped groove of the positioning seat 11 and compresses the spring, so that the positioning pin rotating seat 12 is separated from the positioning seat 11. After the external force is released, the spring resets the limiting rod 15 through the elastic restoring force, so that the positioning pin rotating seat 12 is re-clamped with the positioning seat 11.
