Description

Technical Field

[0001] The present invention belongs to the technical field of processing of RV chassis components, and specifically relates to a production and processing device for lightweight trailer RV chassis components. Background Art

[0002] As an important part of an RV, the trailer RV chassis bears the weight of the vehicle body and interior furniture, and is directly related to driving safety, stability, and riding comfort. The chassis components mainly include key parts such as a towing system, a frame, a suspension system, a braking system, and tires. With the continuous development of new energy technologies, some RVs are driven by new energy forms, and generally mainly use plug-in hybrid and range-extended hybrid methods for driving. Both require arranging an engine or a range extender system, and a battery pack system on the chassis components. Therefore, the installation of the battery pack is often involved in the production and processing of the chassis components.

[0003] Currently, for RV chassis driven by new energy, in order to reduce the center of gravity of the RV and facilitate the arrangement of the battery system, a battery pack system is often installed in the middle position of the chassis. An installation frame for installing the battery pack is generally provided in the middle of the RV chassis driven by new energy. Currently, the installation method of the battery pack is to place the chassis components on a fixed table, and use manual cooperation with a manipulator and other means to carry the battery pack, and place the battery pack in a suitable position for installation. The entire installation process is relatively complex, and rapid positioning installation of the battery pack cannot be achieved.

[0004] At the same time, when installing the battery pack, the current installation method is that after the battery pack arrives, a lifting device is needed to lift the battery pack to the installation position, and then an external automatic screw driving machine is operated to position it to the bolt installation position. During the process of tightening the bolts, the operation of the entire tightening process is extremely cumbersome and urgently needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide a production and processing device for lightweight trailer RV chassis components to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: a production and processing device for a lightweight trailer caravan chassis assembly, including two symmetrically arranged transverse guide rails before and after. Inside both of the two transverse guide rails, there are movably clamped transverse guide blocks. A frame is fixedly connected between the two transverse guide blocks. A bottom plate is fixedly installed at the top of the frame. Above the bottom plate, there is a battery tray. One side of the top of the bottom plate is movably installed with a linkage shaft. The linkage shaft rotates relative to the bottom plate. A limit shaft is fixedly installed at the top of the linkage shaft. One end of the battery tray is movably clamped with the limit shaft. The battery tray is displaced up and down relative to the limit shaft. On the left and right sides of the middle of the bottom plate, there are extension plates installed. Inside the extension plates, there are movably clamped auxiliary locking components. The tops of the auxiliary locking components are symmetrically installed at the left and right sides of the bottom of the battery tray. On the front and back sides of the middle of the bottom of the battery tray, there are auxiliary support seats installed. When the battery tray is located directly above the bottom plate, the bottom ends of the auxiliary support seats are in contact with the top end of the bottom plate. On the relatively far sides of the two auxiliary locking components, there is a laser rangefinder installed.

[0007] Before use, the device can be installed on an external guide rail, and the displacement of the device can be controlled through the external guide rail so that it can be displaced below the trailer caravan chassis assembly to be processed. At the same time, the specification of the battery tray needs to be adjusted according to the specification of the battery pack to be installed to ensure that the size of the battery tray corresponds to that of the battery pack. At the same time, an operator needs to stand on one side of the device for the feeding operation of the battery pack to complete the preparation before processing the chassis assembly.

[0008] As a further technical solution of the present invention, at one end of each of the two transverse guide rails, there is an extension seat installed. On the inner side surfaces of the extension seats, there are main motors installed. At the relatively far ends of the two transverse guide blocks, there are threaded seats installed.

[0009] As a further technical solution of the present invention, a lead screw is threadedly connected to the inner side surface of the threaded seat. The lead screw is movably connected to the transverse guide rail. The lead screw rotates relative to the transverse guide rail. One end of the output shaft of the main motor is connected to the lead screw.

[0010] When it is necessary to install and position the battery pack, the laser rangefinders at one end of the two auxiliary locking components can be used to measure the distances to the left and right ends of the battery installation frame inside the trailer caravan chassis assembly. When the two measured distance data on the left and right are inconsistent, if the value on the left is less than the value on the right, at this time, the main motor can be started to drive the lead screw to rotate. At this time, the threaded seat will move relative to the transverse guide rail under the guiding action of the transverse guide block and the transverse guide rail, and drive the top bottom plate to move relatively, that is, drive the bottom plate and the top battery tray to move to the right until the data of the two laser rangefinders at both ends are exactly the same, and the adjustment process can be completed. At this time, the battery tray can be displaced directly below the battery installation frame.

[0011] By installing a laser rangefinder on one side of the auxiliary locking assembly and utilizing the left and right displacement of the frame and the difference in data measured on both sides, the position of the battery tray can be dynamically adjusted so that the battery tray can be quickly adjusted to the middle position of the battery mounting frame. The entire process can be completed quickly without the need for repeated manual adjustments. Rapid adaptive adjustments can be made to the battery installation of chassis assemblies of different vehicle models, thereby improving the versatility of the device and the installation efficiency.

[0012] As a further technical solution of the present invention, one side of the bottom end of the base plate is fixedly connected to a mounting seat located below the linkage shaft, the inner side of the mounting seat is fixedly connected to a servo motor, and the top end of the servo motor output shaft is connected to the bottom end of the linkage shaft.

[0013] As a further technical solution of the present invention, a main cylinder is symmetrically installed on one side of the top of the base plate away from the linkage shaft, and when the battery tray is located directly above the base plate, the output end of the main cylinder contacts the bottom end of the battery tray.

[0014] When the battery tray is adjusted to the middle position of the battery installation frame, the servo motor can be turned on to drive the linkage shaft to rotate and drive the limit shaft at the top to rotate synchronously. When the limit shaft rotates, the battery tray can be driven to rotate synchronously. When the battery tray rotates to 180 degrees, the battery tray can be located on one side of the bottom plate, which corresponds to the loading station. The operator then places the battery inside the battery tray. After the placement is completed, the linkage shaft continues to rotate 180 degrees until the battery tray is completely located above the bottom plate. At this time, the battery is just located below the battery installation frame, completing the positioning process before installation.

[0015] After positioning is completed, the main cylinder can be opened and controlled to extend. At this time, the main cylinder at the top can push the battery tray upward. At this time, the battery tray moves upward relative to the limit axis until the battery at the top of the battery tray rises to the inside of the installation frame, completing the installation process.

[0016] By utilizing the rotatable battery tray in conjunction with the extension effect of the main cylinder, the battery tray can realize the battery loading, positioning and installation process, so that only one operator is needed to control the battery loading, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, and there is no need for traditional devices to require manual cooperation with robots and the need for repeated positioning. The installation efficiency of the battery pack can be significantly improved, and production costs can be reduced.

[0017] As a further technical solution of the present invention, the auxiliary locking assembly includes a longitudinal guide rail. Vacuum suction cups are installed on both the left and right sides of the bottom end of the longitudinal guide rail. The two longitudinal guide rails are located on the left and right sides of the bottom end of the battery tray. When the battery tray is directly above the bottom plate, the bottom end of the vacuum suction cup adsorbs to the top end of the extension plate.

[0018] As a further technical solution of the present invention, longitudinal guide blocks are movably clamped inside the longitudinal guide rails. The longitudinal guide blocks displace left and right relative to the longitudinal guide rails. Extension shafts are installed at the relatively far ends of the two longitudinal guide blocks. The end of the extension shaft away from the longitudinal guide block penetrates through one end of the longitudinal guide rail and is fixedly connected to a mounting bracket.

[0019] As a further technical solution of the present invention, the two mounting brackets are located on the left and right sides of the battery tray. Automatic screw driving machines are fixedly connected to the top ends of the mounting brackets. First fixing seats are fixedly installed at the top ends of the longitudinal guide blocks.

[0020] As a further technical solution of the present invention, one end of each first fixing seat away from the longitudinal guide block is movably connected to a connecting rod through a rotating shaft. One end of each connecting rod away from the first fixing seat is movably connected to a second fixing seat through a rotating shaft. The top end of the second fixing seat is connected to the bottom end of the battery tray.

[0021] When installing the battery pack upwards, that is, when the battery pack is directly below the battery installation frame, the vacuum suction cups can be activated at this time to control the mutual adsorption between the vacuum suction cups and the extension plate to complete the fixation. When the battery tray displaces upwards under the action of the main cylinder, the two connecting rods at the bottom end deflect at this time, that is, deflect towards the middle, and then drive the longitudinal guide blocks at the bottom end to displace, that is, the longitudinal guide blocks displace relative to the longitudinal guide rails. The two longitudinal guide blocks approach each other accordingly, and drive the two mounting brackets and the automatic screw driving machines to approach each other. When the battery pack rises to the inside of the installation frame, the automatic screw driving machine just displaces to the bolt installation hole position at this time, and the locking process of the battery pack can be automatically completed by controlling the automatic screw driving machine.

[0022] By utilizing the upward installation process of the battery pack and cooperating with the action of the auxiliary locking assembly, when the battery tray rises, the two automatic screw driving machines can approach each other accordingly, quickly positioning them to the bolt installation hole positions. The whole process can be automatically completed without manual control, avoiding the problem that the traditional device needs to lift the battery pack and then use the automatic screw driving machine to position and lock the bolts, simplifying the operation steps and improving the overall production and processing efficiency.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. By using a rotatable battery tray in cooperation with the extension of the main cylinder, the present invention enables the battery tray to achieve the processes of battery loading, positioning, and installation. It only requires one operator to control the battery loading, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, without the problems of manual cooperation with a manipulator and repeated positioning required by traditional devices. It can significantly improve the installation efficiency of the battery pack and reduce production costs.

[0025] 2. By using the upward installation process of the battery pack in cooperation with the auxiliary locking component, when the battery tray rises, the two automatic screw drivers can move relatively closer, enabling them to quickly locate to the bolt installation holes. The whole process can be completed automatically without manual control, avoiding the problems of lifting the battery pack by traditional devices and then using an automatic screw driver to position and lock the bolts. It simplifies the operation steps and improves the overall production and processing efficiency.

[0026] 3. By using a rotatable battery tray in cooperation with the extension of the main cylinder, the present invention enables the battery tray to achieve the processes of battery loading, positioning, and installation. It only requires one operator to control the battery loading, and the battery can be automatically installed inside the battery installation frame. The whole process can be completed quickly, without the problems of manual cooperation with a manipulator and repeated positioning required by traditional devices.

Specific implementation mode

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 8 shown, in the embodiment of the present invention, a production and processing device for a lightweight trailer RV chassis assembly includes two horizontally symmetric horizontal guide rails 1. The interiors of the two horizontal guide rails 1 are both movably clamped with horizontal guide blocks 5. A frame 7 is fixedly connected between the two horizontal guide blocks 5. A bottom plate 8 is fixedly installed at the top of the frame 7. A battery tray 15 is provided above the bottom plate 8. One side of the top of the bottom plate 8 is movably installed with a linkage shaft 11. The linkage shaft 11 rotates relative to the bottom plate 8. A limit shaft 12 is fixedly installed at the top of the linkage shaft 11. One end of the battery tray 15 is movably clamped with the limit shaft 12. The battery tray 15 is displaced up and down relative to the limit shaft 12. Extension plates 14 are installed on both the left and right sides of the middle of the bottom plate 8. The interiors of the extension plates 14 are both movably clamped with auxiliary locking assemblies 17. The tops of the auxiliary locking assemblies 17 are symmetrically installed on both the left and right sides of the bottom of the battery tray 15. Auxiliary support seats 16 are installed on both the front and back sides of the middle of the bottom of the battery tray 15. When the battery tray 15 is located directly above the bottom plate 8, the bottom end of the auxiliary support seat 16 is in contact with the top end of the bottom plate 8. Laser rangefinders are installed on the sides of the two auxiliary locking assemblies 17 facing away from each other.

[0038] Before use, the device can be installed on an external guide rail and the displacement of the device can be controlled through the external guide rail so that it can be displaced below the RV chassis assembly to be processed. At the same time, the specification of the battery tray 15 needs to be adjusted corresponding to the specification of the battery pack to be installed to ensure that the size of the battery tray 15 corresponds to that of the battery pack. At the same time, an operator needs to stand on one side of the device for the feeding operation of the battery pack to complete the preparation before the chassis assembly processing.

[0039] AsFigure 1 and Figure 2 as well as Figure 3 and Figure 4 As shown, extension seats 2 are installed at one end of each of the two transverse guide rails 1, main motors 3 are installed on the inner sides of the extension seats 2, threaded seats 6 are installed at the relatively far ends of the two transverse guide blocks 5, lead screws 4 are threadedly connected to the inner sides of the threaded seats 6, the lead screws 4 are movably connected between the transverse guide rails 1, the lead screws 4 rotate relative to the transverse guide rails 1, and one end of the output shaft of the main motor 3 is connected to the lead screw 4.

[0040] When the battery pack needs to be installed and positioned, the laser rangefinders at one end of the two auxiliary locking assemblies 17 can be used to measure the distances to the left and right ends of the battery installation frame inside the RV chassis assembly. When the two ranging data on the left and right are inconsistent, if the value on the left is less than the value on the right, the main motor 3 can be started at this time, and the lead screw 4 is driven to rotate. At this time, the threaded seat 6 moves relative to the transverse guide rail 1 under the guiding action of the transverse guide block 5 and the transverse guide rail 1, and drives the top plate 8 to displace relatively, that is, drives the top plate 8 and the battery tray 15 at the top to displace towards the right until the data of the laser rangefinders at both ends are exactly the same, and the adjustment process can be completed. At this time, the battery tray 15 can be displaced directly below the battery installation frame.

[0041] By using the laser rangefinders installed on one side of the auxiliary locking assembly 17, and using the left and right displacement of the frame 7 and the difference in the data measured on both sides, the position of the battery tray 15 can be dynamically adjusted, so that the battery tray 15 can be quickly adjusted to the middle position of the battery installation frame. The whole process can be completed quickly, and there is no need for manual repeated adjustment. It can quickly adapt to the battery installation of different vehicle chassis components, improve the versatility of the device, and improve the installation efficiency.

[0042] As Figure 1 and Figure 3 and Figure 5 as well as Figure 6 As shown, a mounting seat 9 located below the linkage shaft 11 is fixedly connected to one side of the bottom end of the top plate 8, a servo motor 10 is fixedly connected to the inner side of the mounting seat 9, and the top end of the output shaft of the servo motor 10 is connected to the bottom end of the linkage shaft 11. Main cylinders 13 are symmetrically installed on one side of the top plate 8 away from the linkage shaft 11. When the battery tray 15 is located directly above the top plate 8, the output end of the main cylinder 13 is in contact with the bottom end of the battery tray 15.

[0043] Embodiment: When the battery tray 15 is adjusted to the middle position of the battery mounting frame, the servo motor 10 can be started at this time, which can drive the linkage shaft 11 to rotate and drive the top limit shaft 12 to rotate synchronously. When the limit shaft 12 rotates, it can drive the battery tray 15 to rotate synchronously. When the battery tray 15 rotates 180 degrees, the battery tray 15 is located on one side of the bottom plate 8 at this time, corresponding to the feeding station. Then the operator places the battery inside the battery tray 15. After the placement is completed, the linkage shaft 11 continues to rotate 180 degrees until the battery tray 15 is completely above the bottom plate 8. At this time, the battery is just below the battery mounting frame, completing the positioning process before installation;

[0044] After completing the positioning, the main cylinder 13 can be started and controlled to extend. At this time, the top main cylinder 13 can push the battery tray 15 to move upward. At this time, the battery tray 15 moves upward relative to the limit shaft 12 until the battery at the top of the battery tray 15 rises into the mounting frame, completing the installation process.

[0045] By using the rotatable battery tray 15 in cooperation with the extension of the main cylinder 13, the battery tray 15 can realize the feeding, positioning and installation processes of the battery, enabling only one operator to control the feeding of the battery and automatically install the battery into the battery mounting frame. The whole process can be completed quickly, without the need for manual cooperation with a manipulator and repeated positioning problems of traditional devices, which can significantly improve the installation efficiency of the battery pack and reduce the production cost.

[0046] Such as Figure 2 and Figure 7 as well as Figure 8As shown in the figure, the auxiliary locking assembly 17 includes a longitudinal guide rail 171. Vacuum suction cups 172 are installed on both the left and right sides at the bottom end of the longitudinal guide rail 171. The two longitudinal guide rails 171 are located on the left and right sides at the bottom end of the battery tray 15. When the battery tray 15 is directly above the bottom plate 8, the bottom end of the vacuum suction cup 172 adsorbs to the top end of the extension plate 14. Longitudinal guide blocks 173 are movably clamped inside the longitudinal guide rails 171. The longitudinal guide blocks 173 displace left and right relative to the longitudinal guide rails 171. Extension shafts 177 are installed at the relatively far ends of the two longitudinal guide blocks 173 away from each other. One end of the extension shaft 177 away from the longitudinal guide block 173 penetrates through one end of the longitudinal guide rail 171 and is fixedly connected to a mounting bracket 178. The two mounting brackets 178 are located on the left and right sides of the battery tray 15. Automatic screw feeders 179 are fixedly connected to the top ends of the mounting brackets 178. First fixing seats 174 are fixedly installed at the top ends of the longitudinal guide blocks 173. Connecting rods 176 are movably connected to the ends of the first fixing seats 174 away from the longitudinal guide blocks 173 through rotating shafts. The ends of the connecting rods 176 away from the first fixing seats 174 are movably connected to second fixing seats 175 through rotating shafts. The top ends of the second fixing seats 175 are connected to the bottom end of the battery tray 15.

[0047] Embodiment: When installing the battery pack upward, that is, when the battery pack is directly below the battery installation frame, the vacuum suction cup 172 can be activated at this time to control the mutual adsorption between the vacuum suction cup 172 and the extension plate 14 to complete the fixation. When the battery tray 15 displaces upward under the action of the main cylinder 13, the two connecting rods 176 at the bottom end deflect at this time, that is, deflect towards the middle, and then drive the longitudinal guide blocks 173 at the bottom end to displace, that is, the longitudinal guide blocks 173 displace relative to the longitudinal guide rails 171. The two longitudinal guide blocks 173 approach each other accordingly, and drive the two mounting brackets 178 and the automatic screw feeders 179 to approach each other. When the battery pack rises to the inside of the installation frame, the automatic screw feeder 179 just displaces to the bolt installation hole position at this time, and the locking process of the battery pack can be automatically completed by controlling the automatic screw feeder 179.

[0048] By utilizing the upward installation process of the battery pack and the function of the auxiliary locking assembly 17, when the battery tray 15 rises, the two automatic screw feeders 179 can approach each other accordingly, quickly positioning them to the bolt installation hole positions. The whole process can be completed automatically without manual control, avoiding the problem of the traditional device needing to lift the battery pack and then using the automatic screw feeder 179 to position and lock the bolts, simplifying the operation steps and improving the overall production and processing efficiency.

[0049] Working principle and usage process:

[0050] Before use, the device can be installed on the external guide rail, and the displacement of the device can be controlled through the external guide rail so that it can be displaced below the motorhome chassis assembly to be processed. At the same time, the specifications of the battery tray 15 need to be adjusted correspondingly according to the specifications of the battery pack to be installed to ensure that the size of the battery tray 15 corresponds to that of the battery pack. At the same time, an operator needs to stand on one side of the device for the feeding operation of the battery pack to complete the preparation before processing the chassis assembly;

[0051] When the installation and positioning of the battery pack are required, the left and right ends of the battery installation frame inside the motorhome chassis assembly can be measured by the laser rangefinders at one end of the two auxiliary locking components 17. When the left and right measurement data are inconsistent, if the value on the left is less than the value on the right, the main motor 3 can be started at this time, and the lead screw 4 is driven to rotate. At this time, the threaded seat 6 moves relative to the transverse guide rail 1 under the guiding action of the transverse guide block 5 and the transverse guide rail 1, and drives the top plate 8 to move relatively, that is, drives the bottom plate 8 and the top battery tray 15 to move to the right until the data of the laser rangefinders at both ends are exactly the same, and the adjustment process can be completed. At this time, the battery tray 15 can be displaced directly below the battery installation frame;

[0052] When the battery tray 15 is adjusted to the middle position of the battery installation frame, the servo motor 10 can be started at this time, which can drive the linkage shaft 11 to rotate and drive the top limiting shaft 12 to rotate synchronously. When the limiting shaft 12 rotates, it can drive the battery tray 15 to rotate synchronously. When the battery tray 15 rotates 180 degrees, the battery tray 15 can be located on one side of the bottom plate 8 at this time, and the feeding station can be correspondingly aligned. The operator then places the battery inside the battery tray 15. When the placement is completed, the linkage shaft 11 continues to rotate 180 degrees until the battery tray 15 is completely located directly above the bottom plate 8. At this time, the battery is just located directly below the battery installation frame, and the positioning process before installation is completed;

[0053] After the positioning is completed, the main cylinder 13 can be opened and controlled to extend. At this time, the top main cylinder 13 can push the battery tray 15 to move upward. At this time, the battery tray 15 moves upward relative to the limiting shaft 12 until the battery at the top of the battery tray 15 rises into the installation frame, and the installation process is completed;

[0054] When the battery pack is installed upward, that is, when the battery pack is directly below the battery installation frame, the vacuum suction cup 172 can be activated at this time to control the mutual adsorption between the vacuum suction cup 172 and the extension plate 14 to complete the fixation. When the battery tray 15 moves upward under the action of the main cylinder 13, the two connecting rods 176 at the bottom deflect at this time, that is, deflect toward the middle, and then drive the longitudinal guide block 173 at the bottom to move, that is, the longitudinal guide block 173 moves relative to the longitudinal guide rail 171. The two longitudinal guide blocks 173 then move closer to each other and drive the two mounting brackets 178 and the automatic screw driver 179 to move closer to each other. When the battery pack rises to the inside of the installation frame, the automatic screw driver 179 just moves to the bolt installation hole position at this time, and the locking process of the battery pack can be automatically completed by controlling the automatic screw driver 179.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
