AI Technical Summary
Existing conveying equipment is too tall to access spaces with low height, resulting in limited applicability, especially as it is difficult to move it under vehicles for carrying and transporting them.
A conveying device comprising a rigid chain assembly, a drive mechanism, and a positioning mechanism is designed. By reducing the size of the rigid chain assembly in the retracted state, and combining the receiving and protruding design of the positioning component, the device can enter a low space in the retracted state. Through the cooperation of the drive mechanism and the positioning mechanism, the vehicle can be stably lifted and positioned.
This technology enables the conveying equipment to operate in low spaces such as under vehicles when it is in a retracted state, eliminating the need for an additional lifting and transfer mechanism. This enhances the applicability and flexibility of the equipment, making it suitable for a wider range of applications.

Wherein the sliding part is configured to be moved along the track under the driving of the support part when the support part moves along the first direction away from the vehicle body, so that the end of the positioning part away from the vehicle body can protrude from the side of the guide seat away from the vehicle body.
[0008] In one of the embodiments, the sliding part is provided with a groove at the end away from the vehicle body along the first direction. In the lifting state, the end of the positioning part close to the vehicle body is limited in the groove.

The first inclined surface is located on the side of the positioning part away from the track along the second direction, and the first inclined surface cooperates with the sliding part. The second inclined surface is arranged obliquely relative to the second direction.
[0010] In one of the embodiments, the positioning part comprises a cooperation part movably arranged in the guide seat along the first direction and a positioning part protruding at the end of the cooperation part away from the vehicle body along the first direction.
[0011] In one of the embodiments, one end of the sliding part extending out of the guide seat is provided with a sliding wheel capable of sliding along the track.
[0012] In one of the embodiments, the lifting assembly further comprises a connecting rod connected between the support part and the guide seat.

[0058] Referring to Figures 1 to 3 The embodiment provides a conveying device 100, comprising a vehicle body 10, a rigid chain assembly 20, a driving mechanism 30 and a positioning mechanism 40. The rigid chain assembly 20 is arranged on the vehicle body 10, and the rigid chain assembly 20 has a support part 211 and has a retracted state and a lifted state. The driving mechanism 30 is drivingly connected to the rigid chain assembly 20, and is used for driving the support part 211 to move along a first direction Z away from the vehicle body 10, so as to switch from the retracted state to the lifted state. In combination with Figure 4 As shown, the positioning mechanism 40 comprises a lifting assembly 41 and a positioning member 42. The lifting assembly 41 is connected to the support part 211 and can move with the support part 211, and the positioning member 42 is movably matched to the lifting assembly 41 along the first direction Z. Among them, as shown in the figure, the lifting assembly 41 is arranged on the support part 211, and the positioning member 42 is arranged on the lifting assembly 41. Figure 4As shown, in the lifting state, the positioning member 42 protrudes from the lifting assembly 41 to the side away from the vehicle body 10. Figure 3 As shown, in the retracted state, the positioning member 42 is accommodated in the lifting assembly 41.
[0059] The above conveying device 100 is provided with the rigid chain assembly 20 on the vehicle body 10, the rigid chain assembly 20 has a support portion 211 to support the vehicle, and the driving mechanism 30 is used to drive the support portion 211 to move along the first direction Z to the side away from the vehicle body 10, so that the rigid chain assembly 20 is in the lifting state, thereby being able to lift the vehicle supported on the support portion 211 to the side away from the vehicle body 10. The rigid chain assembly 20 also has a retracted state, and because the support portion 211 is closer to the vehicle body 10 in the retracted state than in the lifting state, the height of the conveying device 100 along the first direction Z in the retracted state is smaller than the height of the conveying device 100 along the first direction Z in the lifting state, so that the conveying device 100 in the retracted state is convenient to enter a space with a lower height to work. And because the positioning member 42 of the positioning mechanism 40 protrudes from the lifting assembly 41 in the lifting state to position the vehicle supported on the support portion 211, and the positioning member 42 is accommodated in the lifting assembly 41 in the retracted state to further facilitate reducing the height of the conveying device 100 along the first direction Z in the retracted state, the conveying device 100 can enter a lower height application scenario, such as the bottom of the vehicle, without the need to use other adapter mechanisms to lift the vehicle first, and then move the conveying device 100 to the bottom of the vehicle to carry the vehicle. And because the volume of the rigid chain assembly 20 is small, there is a larger space between the vehicle lifted by the rigid chain assembly 20 and the vehicle body 10 in the lifting state, which is convenient for the operator to work under the vehicle.
[0060] In some embodiments, the rigid chain assembly 20 is provided with a mechanical locking mechanism (not shown in the figure) for locking the rigid chain assembly 20.
[0061] In use, the first direction Z can be the height direction of the vehicle. It can be understood that in the lifting state, the support portion 211 can be driven to different positions along the first direction Z by the driving mechanism 30 to meet different requirements for lifting height, such as being applicable to low, medium and high workstations respectively. In the medium or low workstation, the rigid chain assembly 20 lifts the vehicle to a certain height along the first direction Z according to the needs of use, so as to facilitate the operator to work around the vehicle; in the high workstation, the rigid chain assembly 20 lifts the vehicle to the highest position along the first direction Z, and the mechanical locking mechanism is started, so as to facilitate the operator to work under the vehicle. When the work on the vehicle is completed, the rigid chain assembly 20 can be retracted to the lowest position along the first direction Z, so that the positioning member 42 is retracted into the lifting assembly 41, that is, the conveying device 100 is switched to the retracted state, so as to facilitate the conveying device 100 to separate from the vehicle and move out of the bottom of the vehicle.
[0062] Optionally, in the retracted state, the height of the rigid chain assembly 20 along the first direction Z is less than 145 mm, and the height of the conveying device 100 along the first direction Z is less than 165 mm; in the lifted state, the height of the conveying device 100 along the first direction Z is less than or equal to 1800 mm. The maximum height of the positioning member 42 protruding from the vehicle body 10 in the lifted state is 70 mm, so as to be positioned with the vehicle, and the height of the conveying device 100 along the first direction Z in the retracted state is further reduced due to the positioning member 42 being accommodated in the lifting assembly 41, facilitating the free movement of the conveying device 100 at the bottom of the vehicle.
[0063] Figure 5 For Figure 1 the conveying device 100 in the lifted state in the embodiment shown is shown in the schematic view.
[0064] In some embodiments, as Figures 3 to 5 shown, the vehicle body 10 (see Figure 1 ) is provided with a track 11, the track 11 is arranged obliquely relative to the first direction Z, and an end of the track 11 away from the vehicle body 10 is open. The lifting assembly 41 comprises a guide seat 412 and a sliding member 413, the guide seat 412 is connected to the support portion 211, the sliding member 413 is movably arranged in the guide seat 412 along the second direction Y, and an end of the sliding member 413 along the second direction Y protrudes out of the guide seat 412 and can move along the track 11. The positioning member 42 is movably arranged in the guide seat 412 along the first direction Z, and an end of the positioning member 42 close to the vehicle body 10 is in wedge cooperation with the sliding member 413. Wherein, the sliding member 413 is configured to move along the track 11 under the driving of the support portion 211 when the support portion 211 moves away from the vehicle body 10 along the first direction Z, so as to drive the positioning member 42 to protrude out of the guide seat 412 away from the vehicle body 10.
[0065] Thus, when the driving mechanism 30 drives the support portion 211 to move away from the vehicle body 10, the support portion 211 drives the guide seat 412 to move together, so as to drive the sliding member 413 and the positioning member 42 to move away from the vehicle body 10. Since the sliding member 413 is limited in the track 11, and the track 11 is arranged obliquely relative to the first direction Z, when the sliding member 413 moves away from the vehicle body 10 along the first direction Z, the sliding member 413 moves along the track 11, so that the sliding member 413 has a displacement relative to the guide seat 412 along the second direction Y, and further pushes the positioning member 42 to protrude out of the guide seat 412 along the first direction Z through the wedge cooperation, so that the positioning member 42 can be inserted into the reference hole at the bottom of the vehicle to be positioned with the vehicle. Moreover, since the end of the track 11 away from the vehicle body 10 is open, when the sliding member 413 moves to the end of the track 11 away from the vehicle body 10, the sliding member 413 can be separated from the track 11 with the continuous lifting of the rigid chain assembly 20.
[0066] In use, when the sliding member 413 is disengaged from the track 11, the positioning member 42 remains protruding from the guide seat 412, thereby providing positioning for the vehicle at all times. When the work on the vehicle is completed, the rigid chain assembly 20 lowers the vehicle until the sliding member 413 re-enters the track 11, after which the sliding member 413 continues to move toward the side of the vehicle body 10 under the guidance of the guide seat 412 and along the track 11, so that the sliding member 413 has displacement relative to the guide seat 412 in the second direction Y, and the positioning member 42 is retracted into the guide seat 412.
[0067] Figure 6 For Figure 1 An exploded view of the positioning mechanism 40 in the embodiment shown.
[0068] In some embodiments, in combination with Figure 5 and Figure 6 As shown, the sliding member 413 is provided with a groove 413a at one end thereof away from the vehicle body 10 (see Figure 1 ), and in the lifted state, the positioning member 42 is limited in the groove 413a at the end thereof close to the vehicle body 10, so that the positioning member 42 is fixed relative to the sliding member 413 in the lifted state, thereby providing more stable and reliable positioning for the vehicle. In use, in the lifted state, the positioning member 42 is pressed against the sliding member 413 by the vehicle, so that the end of the positioning member 42 close to the vehicle body 10 is pressed into the groove 413a, thereby reliably fixing the positioning member 42 relative to the vehicle and the sliding member 413.
[0069] In some embodiments, as shown in Figure 6 , the positioning member 42 has a first inclined surface 421 and a second inclined surface 422 disposed opposite each other at the end thereof close to the vehicle body 10 (see Figure 1 ), and the end of the first inclined surface 421 close to the vehicle body 10 is connected to the end of the second inclined surface 422 close to the vehicle body 10. The first inclined surface 421 is located on the side of the positioning member 42 away from the track 11 in the second direction Y, and cooperates with the sliding member 413. The second inclined surface 422 is inclined relative to the second direction Y. In this way, the first inclined surface 421 cooperates with the sliding member 413 to form a wedge, and the second inclined surface 422 is provided to gradually reduce the dimension of the end of the positioning member 42 close to the sliding member 413 in the second direction Y, so as to facilitate the movement of the positioning member 42 into the groove 413a and the engagement of the positioning member 42 in the groove 413a. Optionally, the sliding member 413 is provided with a third inclined surface 4131 on the side thereof toward the track 11 in the second direction Y, and the third inclined surface 4131 cooperates with the first inclined surface 421.
[0070] In some embodiments, in combination with Figure 5 and Figure 6As shown, the positioning component 42 includes a mating part 423 and a positioning part 424. The mating part 423 is movably mated to the guide seat 412 along the first direction Z, and the positioning part 424 protrudes from the mating part 423 along the first direction Z away from the vehicle body 10 (see...). Figure 1 One end. Thus, by engaging with the guide seat 412, the mating part 423 provides guidance for the movement of the positioning part 424 along the first direction Z, and the positioning part 424 facilitates positioning with the vehicle when lifting the vehicle. Optionally, the positioning part 424 can be a cylindrical pin.
[0071] In some embodiments, a sliding wheel (not shown) is provided on one end of the slider 413 extending out of the guide seat 412. The sliding wheel can slide along the track 11 to make the movement of the slider 413 along the track 11 smoother.
[0072] In some embodiments, such as Figure 4 As shown, the lifting assembly 41 also includes a connecting rod 414, which connects the support portion 211 and the guide seat 412, allowing the connecting rod 414 and the guide seat 412 to move together with the support portion 211 along the first direction Z. Specifically, the connecting rod 414 is rigidly connected to the support portion 211, and the connecting rod 414 is rigidly connected to the guide seat 412.
[0073] In other embodiments, the positioning member 42 can be protruded or retracted relative to the vehicle body 10 in the first direction Z by a motor drive, or other mechanical means can be used to drive the positioning member 42 to protrude or retract relative to the vehicle body 10 in the first direction Z.
[0074] In some embodiments, such as Figures 1 to 3 As shown, the rigid chain assembly 20 includes two rigid chains 21, which are spaced apart along a second direction Y. The output shaft of the drive mechanism 30 is connected to the two rigid chains 21 respectively, driving the two rigid chains 21 to move together along a first direction Z, thereby enabling the support portions 211 of the two rigid chains 21 to be lifted or lowered synchronously along the first direction Z. Furthermore, by providing two rigid chains 21, the load capacity of the rigid chain assembly 20 is increased. Optionally, the load capacity of the rigid chain assembly 20 is greater than 800 kg. The drive mechanism 30 includes a reducer, which is disposed between the two rigid chains 21, and the output shaft of the reducer is connected to the two rigid chains 21 respectively.
[0075] Optionally, in the contracted state, both rigid chains 21 of the rigid chain assembly 20 extend along a third direction X. The third direction X is perpendicular to the first direction Z and the second direction Y, respectively. Each rigid chain 21 has a support portion 211, and the two support portions 211 of the rigid chain assembly 20 are located on the same side of the vehicle body 10 along the third direction X. The connecting rod 414 extends along the second direction Y, and the two ends of the connecting rod 414 are connected to the two support portions 211, respectively, so that the two support portions 211 can drive the connecting rod 414 to move along the first direction Z together.
[0076] In some embodiments, as shown in Figure 2 , there are multiple rigid chain assemblies 20, and the multiple rigid chain assemblies 20 are distributed along the second direction Y to further improve the overall load capacity of the conveying device 100.
[0077] In some embodiments, as shown in Figure 1 , the vehicle body 10 has a first side 10a and a second side 10b opposite to each other along the second direction Y. There are four rigid chain assemblies 20, two of which are arranged on the first side 10a and are spaced apart along the third direction X, and the other two are arranged on the second side 10b and are spaced apart along the third direction X. In this way, by arranging four rigid chain assemblies 20 on the vehicle body 10, the load of the conveying device 100 is further increased, and the four rigid chain assemblies 20 are arranged on the vehicle body 10 according to the vehicle model hard point requirements. Optionally, the total load of the four rigid chain assemblies 20 is greater than 3200 kg.
[0078] Figure 7 For Figure 1 , a side view of the conveying device 100 in the embodiment shown; Figure 8 , a front view of the conveying device 100 in the embodiment shown. Figure 1
[0079] In some embodiments, as shown in Figure 7 and Figure 8 , the conveying device 100 further includes a traveling mechanism 50 connected to the vehicle body 10 to drive the vehicle body 10 to move to different positions.
[0080] Optionally, the conveying device 100 comprises an AGV (Automated Guided Vehicle), which comprises a vehicle body 10 and a walking mechanism 50. The AGV further comprises an AGV control system for controlling the walking mechanism 50 to drive the vehicle body 10 to move, such as forward and backward walking, left and right translation, or turning in place. In use, before the vehicle is lifted or conveyed by the conveying device 100, the conveying device 100 can be controlled by the AGV control system to enter the vehicle bottom, and then the vehicle is supported and positioned on the conveying device 100, so as to lift or convey the vehicle. After the vehicle is operated, the conveying device 100 is switched from the lifting state to the retracted state, and then the conveying device 100 is moved out of the vehicle bottom by the AGV control system.
[0081] The conveying device 100 described above has higher flexibility than the rigid conveying by setting the AGV, and can be conveyed to the required position alone, for example, the vehicle can be conveyed to different positions after being loaded on the conveying device 100, so as to facilitate the debugging or process verification of the vehicle, thereby facilitating the shortening of the debugging and verification period of the vehicle. Since the conveying device 100 is provided with a plurality of rigid chain assemblies 20, the load capacity of the conveying device 100 is large, and the conveying device 100 can be applied to the vehicle assembly workshop and can convey and lift the fuel vehicle or new energy vehicle. And since the conveying device 100 is easy to produce and manufacture, it is easy to increase the number of conveying devices 100 according to the needs, avoiding the problems of long new construction or modification period and high cost caused by using rigid line conveying. By setting a plurality of rigid chain assemblies 20, the conveying device 100 can be lifted to different heights in the first direction Z in the lifting state, thereby meeting the requirements of low, medium and high workstations respectively. The height of the conveying device 100 in the first direction Z in the retracted state is low, and the AGV control system can automatically move out of the vehicle bottom, so there is no need to add other switching mechanisms to separate the conveying device 100 from the vehicle.
[0082] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
