Description

Technical Field

[0001] This invention relates to the field of automotive tooling equipment, specifically a vehicle lifting device and assembly station. Background Technology

[0002] Currently, to improve the utilization rate of existing production lines and reduce investment in land, factory infrastructure, and process equipment, traditional automakers inevitably produce new energy vehicles on the same production lines as traditional gasoline vehicles. The existing production lines for gasoline vehicles often lack sufficient capacity, and upgrading them would render them unusable, while also resulting in longer production cycles and impacting overall economic efficiency. Therefore, there is an urgent need for a vehicle lifting device that can meet the lifting requirements of both traditional gasoline vehicle chassis and new energy vehicle assembly requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a vehicle lifting device that facilitates vehicle lifting, provides stable lifting, and occupies a small area.

[0004] The objective of this invention can be achieved through the following technical solutions:

[0005] A vehicle lifting device includes a frame, two swing arm support assemblies, a drive assembly, and a locking assembly. The two swing arm support assemblies are slidably connected within the frame and are used to support the bottom sides of the vehicle, respectively. The drive assembly is driven to both swing arm support assemblies and is used to drive the two swing arm support assemblies to slide synchronously within the frame. The locking assembly is disposed on one side of the swing arm support assembly and is used to limit the height of the swing arm support assembly sliding within the frame.

[0006] In a further embodiment, the frame includes columns, longitudinal beams, and transverse braces, with the longitudinal beams connected to the columns and the transverse braces connected to the longitudinal beams.

[0007] In a further embodiment, a slide rail is provided on one side of the column, and the swing arm support assembly includes guide wheels, a support frame, a swing arm, and a first telescopic cylinder. There are multiple guide wheels, which are rotatably connected to both ends of the support frame. The support frame is slidably connected to the slide rail through the guide wheels. The middle part of the swing arm is rotatably connected to the support frame. One end of the first telescopic cylinder is connected to the end of the swing arm near the support frame, and the other end of the first telescopic cylinder is connected to the side wall of the support frame.

[0008] In a further embodiment, the drive assembly includes a drive motor, a drive shaft, a first drive chain, a drive sprocket, a fixed base plate, a second drive chain, a third drive chain, a first driven sprocket, and two second driven sprockets. The drive motor is connected to the fixed base plate, which is connected to the cross brace. The two ends of the drive shaft are rotatably connected between the two longitudinal beams. Multiple drive sprockets are connected to the ends and middle of the drive shaft, as well as to the drive motor shaft. The two ends of the first drive chain are connected to the drive sprockets at the middle of the drive shaft and the drive motor shaft. One driven sprocket and two second driven sprockets are rotatably connected to the longitudinal beam, and the two second driven sprockets are located directly above both ends of the support frame. The first driven sprocket is connected between the two second driven sprockets. The second drive chain is circular, and the two ends of the circular chain are connected to the drive sprocket at the end of the drive shaft and the first driven sprocket. Chain branch joints are provided on both the upper and lower sides of the circular chain. One end of the third drive chain is connected to the chain branch joint, the other end is connected to one end of the support frame, and the middle part is driven connected to the second driven sprocket directly above one end of the support frame.

[0009] In a further embodiment, the chain branch connector has three connecting ends, which are interconnected in a Y-shape. Two of the connecting ends are connected to the second drive chain, and the other connecting end is connected to the third drive chain.

[0010] In a further embodiment, the drive assembly further includes a chain tensioning assembly, which is connected to the middle of the second drive chain and is used to tension the second drive chain.

[0011] In a further embodiment, the chain tensioning assembly includes a threaded sleeve and two adjusting rods, one end of which is threadedly connected to the threaded sleeve, and the other end is fixedly connected to the second drive chain.

[0012] In a further embodiment, the locking assembly includes a sliding pin, a pin rail seat, a second telescopic cylinder, and a pin buckle. The pin buckle is disposed on the upper part of the swing arm support assembly. The pin rail seat is fixedly connected to one side of the pin buckle. One end of the sliding pin is slidably connected inside the pin rail seat and can engage with the pin buckle to lock the swing arm support assembly. The other end of the sliding pin is hinged to the telescopic rod of the second telescopic cylinder. The cylinder body of the second telescopic cylinder is fixed to the side of the pin rail seat away from the pin buckle.

[0013] Another objective of this invention is to provide a vehicle assembly station for improving the assembly efficiency of existing new energy vehicles.

[0014] The objective of this invention can be achieved through the following technical solutions:

[0015] A vehicle assembly station includes any one of the aforementioned vehicle lifting devices, a car handling robot, a battery handling robot, a safety scanner, and detection switches. The car handling robot is disposed on one side of the vehicle lifting device and is used to transport the vehicle frame into the vehicle lifting device. The battery handling robot is disposed on one side of the car handling robot and is used to transport the battery into the vehicle lifting device. The safety scanner is disposed above the vehicle lifting device and is used to detect whether there is a vehicle to be transported or an empty space below the vehicle lifting device. Multiple detection switches are connected to the vehicle lifting device and are used to detect vehicle position signals and transmit the detected signals to the car handling robot, the battery handling robot, and the safety scanner.

[0016] In a further embodiment, the vehicle assembly stations are multiple and connected side by side.

[0017] The beneficial effects of this invention are:

[0018] This invention provides support during vehicle lifting via a frame. A swing support assembly allows the vehicle to swing in or out of the vehicle's underside. A drive assembly, when the swing support assembly is in place, drives the swing arm support assembly to slide within the frame, thus lifting the vehicle to a predetermined work position. Simultaneously, a locking assembly locks the swing arm support assembly at this work position, achieving mechanical locking of the vehicle. After the process at this work position is completed, the locking assembly can be released, and the drive assembly reverses the direction, returning the vehicle to its initial position within the lifting device. This facilitates vehicle processing and assembly, improves tooling efficiency, and enhances safety.

[0019] Existing lifting devices typically use electric hoists to lift multiple chains, which can apply circumferential tension to the vehicle's perimeter. The drive assembly of this application can lift multiple chains with a single motor, and it also prevents the problem of chains accumulating inside the electric hoist, which can easily damage the hoist. Furthermore, the control of each electric hoist is not easy to synchronize. Therefore, this application can achieve more stable lifting of the vehicle.

[0020] Existing assembly workstations typically consist of assembly stations, robots, and other robots, with the robots serving primarily as transport tools. The assembly workstation proposed in this invention, however, comprises multiple car transport robots, multiple parallel-arranged assembly stations, and multiple battery transport robots. Through interaction between various types of robots and safety scanners and detection switch signals on the assembly stations, and by switching between different robot types and assembly workstation processes, multi-stage and multi-unit transport, delivery, and assembly are achieved, thereby improving vehicle assembly efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figure 1 As shown, a vehicle lifting device includes a frame 1, two swing arm support assemblies 2, a drive assembly 3, and a locking assembly 4. The two swing arm support assemblies 2 are slidably connected within the frame 1 and are used to support the bottom sides of the vehicle, respectively. The drive assembly 3 is drivenly connected to both swing arm support assemblies 2 and is used to drive the two swing arm support assemblies 2 to slide synchronously within the frame 1. The locking assembly 4 is disposed on one side of the swing arm support assembly 2 and is used to limit the height of the swing arm support assembly 2 sliding within the frame 1.

[0037] Its working principle is as follows: the frame 1 is used to install and support the swing arm support assembly 2, the drive assembly 3, and the locking assembly 4. The swing support assembly can swing in or out of the bottom of the vehicle. When the swing support assembly is swung into the bottom of the vehicle, the drive assembly 3 drives the swing arm support assembly 2 to slide within the frame 1, thereby lifting the vehicle to the predetermined work position. At the same time, the locking assembly 4 locks the swing arm support assembly 2 at this work position, thereby achieving mechanical locking of the vehicle. After the process at this work position is completed, the locking assembly 4 can be used to unlock the swing arm support assembly 2, and the drive assembly 3 drives it in the opposite direction, so that the vehicle returns to the initial position when it entered the lifting device, thereby facilitating the processing and assembly of the vehicle and improving tooling efficiency.

[0038] Based on the above working principle, some preferred implementation structures or methods are provided. Frame 1 includes columns 11, longitudinal beams 12, and cross braces 13. The longitudinal beams 12 are connected to the columns 11, and the cross braces 13 are connected to the longitudinal beams 12. Frame 1 as a whole can be in the form of a gantry structure. Gantry structures provide good support. The material of the columns 11 can be H-beams, which provide strong support and facilitate the installation of testing components. The number of columns 11, longitudinal beams 12, and cross braces 13 can be determined according to actual installation requirements and is not limited to a specific number. The overall structure is not limited to a gantry structure.

[0039] A slide rail 14 is provided on one side of the column 11, such as... Figure 2 As shown, the swing arm support assembly 2 includes guide wheels 21, support frame 22, swing arm 23 and first telescopic cylinder 24. There are multiple guide wheels 21, which are rotatably connected to both ends of the support frame 22. The support frame 22 is slidably connected to the slide rail 14 through the guide wheels 21. The middle part of the swing arm 23 is rotatably connected to the support frame 22. One end of the first telescopic cylinder 24 is connected to the end of the swing arm 23 near the support frame 22, and the other end of the first telescopic cylinder 24 is connected to the side wall of the support frame 22. The guide wheels 21 of the support frame 22 can be divided into guide wheel one and guide wheel two. The axles of guide wheel one and guide wheel two are perpendicular and cooperate with the surface of the slide rail 14 to guide and ensure vertical rise and fall during the lifting process. The swing support assembly can be composed of two sets of support frames 22, which are used to lift the two sides of the vehicle respectively. Each support frame 22 moves up and down in the slide rail 14 through guide wheels. Each support frame 22 is equipped with two swing arms 23 that can be folded outward by 90 degrees. After the swing arms 23 are opened, a support block can be set on the swing arms 23. The support block supports the skirt position between the two wheels of the car. After the swing arms 23 are folded outward by 90 degrees, the inner width does not affect the car's entry and exit from the lifting device. The swing arms 23 are installed on the support frame 22 as a whole. The folding of the swing arms 23 is realized by the first telescopic cylinder 24. The folding signal can be detected by the detection switch 7 set at the folding position and transmitted to the control center. This facilitates the vehicle's entry and the automatic control of lifting the vehicle after entry, improving work efficiency.

[0040] The number of components in the aforementioned swing arm support assembly 2, slide rail 14, and swing arm support assembly 2 can be determined according to actual installation requirements and is not limited to a specific number.

[0041] See Figure 1 The driving component 3 shown includes (see reference) Figure 1 The drive motor 31, drive shaft 32, first drive chain 33, drive sprocket 34, fixed base plate 35, and references are shown. Figure 4 The second drive chain 36, the third drive chain 37, the first driven sprocket 38, and the two second driven sprockets 39 are shown in the attached diagram. Figure 3As shown, the drive motor 31 is connected to the fixed base plate 35, which is connected to the cross brace 13. The two ends of the drive shaft 32 are rotatably connected between the two longitudinal beams 12. Multiple drive sprockets 34 are connected to the ends and middle of the drive shaft 32, as well as the shaft of the drive motor 31. The two ends of the first drive chain 33 are connected to the drive sprockets 34 at the middle of the drive shaft 32 and the shaft of the drive motor 31. (See reference...) Figure 1 and Figure 4 The first driven sprocket 38 and two second driven sprockets 39 are rotatably connected to the longitudinal beam 12, and the two second driven sprockets 39 are located directly above both ends of the support frame 22. The first driven sprocket 38 is connected between the two second driven sprockets 39. The second drive chain 36 is ring-shaped, with its two ends connected to the drive sprocket 34 at the end of the drive shaft 32 and the first driven sprocket 38, respectively. Chain branch joints 361 are provided on both the upper and lower edges of the ring. One end of the third drive chain 37 is connected to the chain branch joint, and the other end is connected to one end of the support frame 22. The middle part is connected to the second driven sprocket 39 directly above one end of the support frame 22. The drive motor 31 and the fixed base plate 35 are connected by a screw and nut. The tension of the first drive chain 33 is achieved by adjusting the motor mounting height by adjusting the nut. (See reference...) Figure 1 , Figure 3 and Figure 4 As shown, the drive motor 31 is bolted to the top of the cross brace 13. The drive sprockets 34 at both ends of the drive shaft 32 drive two second drive chains 36 to rotate. Each second drive chain 36 is mounted on the longitudinal beam 12 above the two columns 11 on the same side. The chain can be wrapped inside the longitudinal beam 12, thereby driving the four third drive chains on the chain branch joint 361 to lift synchronously, so that the two swing arm support assemblies 2 can lift and lower the vehicle synchronously. This connection of the second drive chains 36 allows for a more balanced tension to be applied to the third drive chains 37, thereby ensuring the balance at both ends of the support frame 22 during lifting and ensuring that the vehicle remains balanced and stable during the lifting process.

[0042] The installation and connection methods of the various parts of the aforementioned drive assembly 3 can refer to the existing installation of similar parts. For example, the two ends of the drive shaft 32 can be rotatably connected by bearings. If the length of each chain is too long, an idler wheel 303 can be added to tension the chain, support and guide it, and further tension it.

[0043] like Figure 4 As shown, the chain branch connector 361 has three connecting ends, which are interconnected in a Y-shape. Two of the connecting ends are connected to the second drive chain 36, and the other connecting end is connected to the third drive chain 37. This saves chain length and avoids chain curling and stacking, which can cause chain interference and affect the stable transmission of power to the drive assembly 3.

[0044] See Figure 1 As shown, each support frame 22 is connected to two third drive chains 37 at both ends, and is also matched with two second drive chains 36 on the drive shaft 32 to ensure that there is no off-center load during the lifting process. The second drive chains 36 are driven by the first drive chains 33, and the tension of the second drive chains 36 is achieved by the chain tensioning assembly 30. The chain tensioning assembly 30 is connected to the middle of the second drive chains 36 and is used to tension the second drive chains 36.

[0045] See Figure 5 As shown, the chain tensioning assembly 30 includes a threaded sleeve 301 and two adjusting rods 302. One end of each adjusting rod 302 is threadedly connected to the threaded sleeve 301, and the other end is fixedly connected to the second drive chain. By moving the two adjusting rods 302 in opposite directions, the tension of the chain connected at both ends can be mechanically adjusted, thereby preventing chain derailment. The aforementioned sprocket and chain assembly structure can also be partially or completely replaced with a high-strength synchronous belt and pulleys.

[0046] See Figure 6 As shown, the locking assembly 4 includes a sliding pin 41, a pin rail seat 42, a second telescopic cylinder 43, and a pin buckle 44. The pin buckle 44 is located on the upper part of the swing arm support assembly 2. The pin rail seat 42 is fixedly connected to one side of the pin buckle 44. One end of the sliding pin 41 is slidably connected in the pin rail seat 42 and can be engaged with the pin buckle 44 to lock the swing arm support assembly 2. The other end of the sliding pin 41 is hinged to the telescopic rod of the second telescopic cylinder 43. The cylinder body of the second telescopic cylinder 43 is fixed on the side of the pin rail seat 42 away from the pin buckle 44.

[0047] Both ends of the support frame 22 are equipped with pins 44; sliding pins 41 are respectively installed at appropriate positions on the column 11. After the support frame 22 is raised to the position, the sliding pins 41 are inserted into the pins 44 to achieve a safe lock. The sliding pins 41 extend and retract within the pin rail seat 42, and the supporting force is borne by the pin rail seat 42, avoiding direct force on the cylinder and damage. The second telescopic cylinder 43 is movably connected to the sliding pins 41 for easy replacement. The second telescopic cylinder 43, the pin rail seat 42, and the detection switch 7 for the positioning signal of the second telescopic cylinder 43 are all installed on the mounting base plate, and then the entire assembly is installed on the slide rail 14 through the mounting base plate. The extension and retraction position of the second telescopic cylinder 43 is fed back by the detection switch 7 below.

[0048] The number of the above-mentioned parts can be appropriately increased, taking into account the supporting strength, and is not limited to a certain number.

[0049] A vehicle assembly station includes the aforementioned vehicle lifting device, see reference. Figure 7 The car handling robot 5, battery handling robot 6, safety scanner, and detection switch 7 shown are described in the attached document. Figure 7The car handling robot 5 shown is positioned on one side of the vehicle lifting device to move the car frame to the area below the vehicle lifting device. The battery handling robot 6 is positioned on one side of the car handling robot 5 to move the battery to the area below the vehicle lifting device. A safety scanner is positioned above the vehicle lifting device to detect whether there is a vehicle to be moved or an empty space below the vehicle lifting device. (See reference...) Figure 6 and Figure 2 Multiple detection switches 7 are connected to the vehicle lifting device. These switches detect the vehicle position signal and transmit it to the car handling robot 5, the battery handling robot 6, and the safety scanner. Multiple switches are connected in parallel at the assembly station to meet production cycle requirements.

[0050] Its specific implementation method may be:

[0051] See Figure 1 As shown, the swing arm support assembly 2 is in a low position, and the swing arm 23 is in a folded state, parallel to the vehicle skirt and support frame 22, facilitating the passage of the entire vehicle. When the safety scanner detects that there are no people or other equipment in the island, the assembly station reaches the state where the entire vehicle can enter. At this time, the car handling robot 5 is not equipped with a battery and has the same load as a traditional fuel vehicle. After being automatically transported from the production line to the assembly station, it proceeds to the waiting point outside the work station. Currently, the swing arm 23 is opened by the first telescopic cylinder 24 to a 90-degree angle with the support frame 22, and is positioned just below the vehicle skirt. Figure 8 As shown. The drive motor 31 drives the first drive chain 33, the second drive chain 36, and the third drive chain 37 to move sequentially. The third drive chain 37 drives the support frame 22 to rise. When the swing arm 23 contacts the vehicle, it will drive the entire vehicle to rise. After reaching the preset position, the sliding pin 41 is driven by the second telescopic cylinder 43 to insert into the pin buckle 44 set on the support frame 22 to achieve mechanical locking of the support frame 22. Figure 9 As shown.

[0052] like Figure 10 As shown, the battery pack is manually placed on top of the battery handling robot 6, which then quickly moves to another exit of the assembly station to wait for... Figure 6 When the detection switch 7 is detected and the locking state is completed, the battery handling robot 6 automatically enters the accurate position under the vehicle battery. After the manual operation of the battery handling robot 6 to lift and complete the battery assembly, hole alignment and tightening, it automatically descends to the position and returns to the starting position empty. The personnel leave the automatic assembly station. When the safety scanner detects that there are no personnel or equipment under the vehicle, it means that the operation is completed. The sliding pin 41 disengages from the pin buckle 44, and the assembly station slowly lowers the vehicle to the ground.

[0053] The swing arm 23 continues to descend following the support frame 22 to the starting point, detaching from the vehicle's side skirt. At this point, the swing arm 23 is folded, and the vehicle is ready for transport. Meanwhile, the car handling robot 5, located at the waiting point on one side of the assembly station, enters under the vehicle, clamps it, and automatically delivers it to the inspection line. Figure 11 As shown.

[0054] like Figure 12 As shown, the assembly station of the present invention is a multi-unit parallel configuration, see reference. Figures 1-12 The assembly station shown has two entrances / exits: one for personnel and car handling robot 5, and the other for personnel and battery handling robot 6. This allows for the division of work areas for different types of robots through the assembly station, ensuring clear logic during operation and preventing interference issues. Simultaneously, multiple parallel workstations with the same number of robots can operate at the same time, achieving continuous overall cycle time and process.

[0055] The assembly station's workflow can be as follows: after a vehicle arrives at the static adjustment line, a vehicle transfer robot is dispatched through a data platform to receive the vehicle.

[0056] The vehicle is transferred to the waiting area, where it awaits scheduling by the assembly station's data platform. Once the vehicle arrives at its designated assembly station, it is unloaded, and the transfer robot leaves the station and moves to the waiting position.

[0057] After the vehicle enters the station, press the confirmation button on the control panel, and the assembly station will automatically lift the vehicle to the set height.

[0058] The assembly station dispatches battery robots to deliver batteries to the station. Upon arrival, the battery robots automatically lift the power batteries to a set height.

[0059] After the power battery is lifted, personnel enter the assembly station to complete assembly tasks such as fixing the battery pack.

[0060] After the chassis assembly is completed, the vehicle is lowered into position, and personnel complete the battery antifreeze filling, safety inspection, electrical inspection and other related work.

[0061] After the on-island operations are completed, the assembly station dispatches a vehicle transfer robot to pick up the vehicle and transfer it to the off-line point, where the vehicle waits to enter the testing line to complete the subsequent procedures.

[0062] Before lifting and lowering operations at the assembly station, the safety of personnel and machines is confirmed by a safety scanner before any work is carried out. To ensure safety during battery and vehicle assembly, a sliding pin 41 is installed to mechanically lock the entire lifting mechanism. Movable pins are installed at both ends of the left and right support frames 22 at the assembly station to ensure that both ends of a single support frame 22 are secured by the insertion of pins, thus ensuring the absolute safety of personnel. The folding and opening states of the swing arm 23, the lifting and lowering operation status of the hoist, and the extension and retraction status of the movable pins are all monitored by the detection switch 7. If any of the above information is missing, the workstation will not proceed to the next step.
