Description

Technical Field

[0001] This utility model relates to the technical field of automotive door component transportation and storage devices, specifically to a common material rack for vehicle stamped door inner panels. Background Technology

[0002] The inner panel of a vehicle door is the core supporting component of the door structure and the base for installing various accessories. It is usually made of high-strength steel plate or composite material through stamping.

[0003] Since the inner panel of the vehicle door is a stamped part with a regular, evenly distributed, and flat shape, it will be deformed if it is stacked. Therefore, after the inner panel of the vehicle door is stamped, a special rack is needed to hang it to ensure that it will not be deformed by external forces during storage and transportation.

[0005] However, as people pursue personalization in their cars, the automotive industry is constantly developing and changing, resulting in a production model of multiple models and small batches. This leads to an increase in the types of stamped parts. Often, the production of a new model is accompanied by the scrapping of the old model's stamped parts rack and the investment in the new model's rack. However, each investment in the new model's rack represents an increase in production costs. Therefore, there is an urgent need to develop a rack for stamping door inner panels that can be applied to various types of door inner panels, so as to achieve commonality for stamping door inner panels of various vehicles. Summary of the Invention

[0006] In order to overcome the shortcomings of the existing technology where the material rack for vehicle stamping door inner panels is frequently changed due to changes in vehicle models, resulting in increased production costs, this utility model provides a common material rack for vehicle stamping door inner panels.

[0007] The technical solution of this utility model to solve its technical problem is: a common material rack for vehicle stamping door inner panels, comprising:

[0008] The outer frame includes side frames on both sides and a rear frame at its rear end;

[0009] A hanging cylinder is connected to the rear frame and protrudes inward toward the outer frame, allowing the inner panel of the stamped door to be suspended from the hanging cylinder.

[0010] A limiting rod is connected to the side frame and protrudes towards the inside of the outer frame. The limiting rod can abut against the surface of the inner panel of the stamped door to prevent the inner panel of the stamped door from moving back and forth relative to the outer frame.

[0011] A flip plate is connected to the side frame and is disposed facing the inside of the outer frame. The flip plate can abut against the left and right sides of the inner panel of the stamped door to prevent the inner panel of the stamped door from moving left and right relative to the outer frame.

[0012] Several connecting seats are fixedly provided on the inner side of the rear frame, and the connecting seats are arranged from top to bottom. The hanging cylinder is connected to the rear frame by being sleeved on the connecting seats, and the hanging cylinder can be replaced between the various connecting seats so that the hanging cylinder can be connected to different positions of the rear frame. A quick-release structure is also provided between the hanging cylinder and the connecting seat, and the hanging cylinder and the connecting seat are relatively fixed through the quick-release structure.

[0013] Furthermore, the connecting seat includes a cylindrical body protruding from the inner side of the rear frame. The cylindrical body is hollow and has an opening at its front end. The hanging cylinder can be axially inserted into the cylindrical body through the opening to achieve the connection and engagement between the hanging cylinder and the connecting seat.

[0014] Furthermore, the quick-release structure includes a fixing pin, and the cylindrical body of the connecting seat is provided with an outer fixing hole in the radial direction, while the hanging cylinder is provided with an inner fixing hole in the radial direction. When the hanging cylinder is sleeved in the cylindrical body, rotating the hanging cylinder can make the inner fixing hole and the outer fixing hole coincide, thereby achieving relative fixation between the cylindrical body and the connecting seat by passing the fixing pin through the outer fixing hole and the inner fixing hole.

[0015] Furthermore, a positioning block is protruding on the side wall of the hanging cylinder, and a positioning groove is also provided on the front end of the cylinder at the side of the opening. After aligning the positioning block on the hanging cylinder with the positioning groove on the cylinder, the hanging cylinder is then inserted into the cylinder. At the same time, the positioning block is snapped into the positioning groove, and the inner fixing hole and the outer fixing hole coincide.

[0016] Furthermore, a baffle is also provided on the upper side of the opening at the front end of the hanging cylinder, and a protective pad is connected to the baffle. When the inner panel of the stamping door is suspended on the hanging cylinder, the rear side of the inner panel of the stamping door can abut against the protective pad, while the limiting rod abuts against the front side of the inner panel of the stamping door, thereby preventing the inner panel of the stamping door from moving back and forth relative to the outer frame.

[0017] Furthermore, there are two hanging cylinders, and the connecting seats are arranged in pairs, with the two connecting seats in each group symmetrically arranged on the rear frame; there are two limiting rods, which are symmetrically arranged on the left and right side frames; there are two flip plates, which are symmetrically arranged on the left and right side frames.

[0018] Furthermore, the side frame also includes a sliding cylinder, and a sliding sleeve is fixedly provided at one end of the limiting rod. The sliding sleeve is sleeved on the sliding cylinder and can slide along the sliding cylinder so that the limiting rod can move back and forth relative to the outer frame. The sliding cylinder also has several inner insertion holes arranged along its length, and the sliding sleeve has an outer insertion hole. By inserting a pin into the outer insertion hole and the inner insertion hole, the relative position between the sliding cylinder and the sliding sleeve can be fixed.

[0019] Furthermore, the side frame also includes a pivot, one side of the flip plate is hinged to the pivot, and the other end of the flip plate is provided with a stop post for abutting against the inner panel of the stamped door. The flip plate flips relative to the side frame to move the stop post closer to or further away from the inner panel of the stamped door. A limiting plate is also connected to the rear frame. When the flip plate flips down to the lowest position, the limiting plate can abut against the flip plate to prevent the flip plate from continuing to flip down.

[0020] Furthermore, a limiting foot is also provided on the inner side of the rear frame near the bottom. The limiting foot is located below the hanging cylinder. When the inner panel of the stamping door is suspended on the hanging cylinder, the limiting foot can abut against the bottom of the inner side of the inner panel of the stamping door.

[0021] Furthermore, an oil collection plate is connected to the upper side of the bottom of the outer frame, and several support legs are connected to the lower side of the bottom of the outer frame. The outer frame is supported on the plane by the support legs.

[0022] The hanging process of the vehicle stamped door inner panel in this utility model:

[0023] First, adjust the position of the hanging cylinder according to the position of the holes on the inner panel of the stamped door of the vehicle to be hung. During the adjustment process, first remove the fixing pin on the connecting seat that the original hanging cylinder was connected to, then remove the hanging cylinder from the original connecting seat, align the hanging cylinder with the opening on the connecting seat to be assembled, and align the positioning block on the hanging cylinder with the positioning groove on the connecting seat before inserting the hanging cylinder into the connecting seat. Then, insert the fixing pin into the outer fixing hole and the inner fixing hole to complete the fixed connection between the hanging cylinder and the connecting seat. After the hanging cylinder is positioned, first flip the left and right flip plates upwards, and then hang the vehicle... Align the holes on the inner door panel of the vehicle with the hanging cylinder, fit the entire inner door panel onto the hanging cylinder, and push the inner door panel backward so that its rear side can abut against the protective pad on the connecting seat. At this time, the lower end of the inner side of the inner door panel also abuts against the limiting foot. Then rotate the limiting rod around the sliding cylinder to the horizontal and then move the limiting rod backward so that the limiting rod can abut against the front side of the inner door panel. Then pass the pin through the outer insertion hole and the inner insertion hole to fix the position of the limiting rod. At this time, the forward and backward movement of the inner door panel is restricted. Finally, flip the left and right flip plates downward so that they abut against the left and right sides of the inner door panel to restrict its left and right movement.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. The position of the hanging cylinder on the outer frame of the material rack can be adjusted and moved according to the needs. It is equipped with a connecting seat to connect the hanging cylinder and a quick-release structure to fix the hanging cylinder, which further ensures the stability after the position of the hanging cylinder is adjusted. This makes the material rack suitable for hanging the inner panels of stamped doors of various types of vehicles, realizing the common use of the material rack and thus effectively saving production costs.

[0026] 2. A baffle and a protective pad are also installed on the connecting seat. When the vehicle stamping door inner panel is installed in place, the protective pad will abut against it, which can effectively prevent the door inner panel from deforming due to collision with the connecting seat during transportation.

[0027] 3. The movement of the limit rod relative to the outer frame is also very convenient, and a pin is provided to fix the position of the limit rod. This not only improves the efficiency of installing the inner door panel of the vehicle stamping on the material rack, but also ensures the firmness of the inner door panel on the material rack after installation.

[0028] 4. A limit plate is also provided on the outer frame to restrict the downward flipping of the flipping plate. This can effectively prevent the flipping plate from flipping down too far under the action of gravity when the inner panel of the vehicle stamping door is not installed on the material rack, thus avoiding collision with the outer frame and preventing damage to the flipping plate and the outer frame.
