[0062] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0067] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0068] The present application provides a skid conveying system for use in vehicle production. The vehicle may be a large automobile, a small automobile, a special-purpose vehicle, or the like. For example, based on the vehicle type, the vehicle in the present application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other vehicle types. A vehicle generally comprises wheels, a power source, and a transmission system disposed between the wheels and the power source. The transmission system transmits power from the power source to the wheels, causing the wheels to rotate, thereby driving the vehicle.

[0069] It should be noted that in the embodiments of this application, the type of vehicle power source is not limited. For example, for a fuel-powered vehicle, the power source may refer to a gasoline engine, a diesel engine, or other fuel-powered engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; and for a vehicle powered by other means, the power source may refer to a device that generates power.

[0070] A skid is used to transport vehicle body parts from one workstation to the next so that the parts can be installed on the body parts. The body parts can be part of the vehicle body, such as crossbeams, longitudinal beams, or side beams. Currently, in order to accurately position the body parts in their current predetermined positions, the positioning components on the skid are typically connected to the body parts via adapter brackets. Specifically, before the positioning components are positioned, one or more adapter brackets are first connected to the body parts. When the skid transfers the body parts to the positioning components, these positioning components dock with the adapter brackets, facilitating the positioning of the body parts in their current positions. After the assembly process at the current workstation is completed, the adapter brackets are removed from the body parts without affecting the body parts. However, when the adapter brackets are connected to the body parts, there is no anti-misinstallation structure between the adapter brackets and the body parts, which sometimes results in the adapter brackets being misinstalled. This causes the positioning components to fail to properly dock with the first positioning portion on the adapter bracket, meaning that the body parts are not in their predetermined positions, thus affecting the smooth progress of production.

[0071] Based on the above problems, an embodiment of the present application provides a skid conveying system, including a skid body and a support body, and the skid body is provided to convey the vehicle body parts so that the body parts can be moved from the current workstation to the next workstation, and the support body is provided on the skid body, and a placement portion for placing the parts to be connected is provided on the support body, wherein the placement portion supports the parts to be connected for connection with the body parts and limits their position on the support body so that the first positioning portion on the parts to be connected faces the first preset direction, thereby ensuring that the parts to be connected are correctly connected to the body parts, avoiding the situation where the positioning component on the skid body cannot dock with the first positioning portion due to incorrect installation, and is conducive to the smooth progress of vehicle production and assembly.

[0072] The following is a detailed description of the skid conveying system provided in the embodiments of the present application in conjunction with the accompanying drawings.

[0073] Reference Figure 1-Figure 7 As shown, an embodiment of the present application further provides a skid conveying system that can be used in vehicle production. The skid conveying system includes a skid body 100 and a support body 200 .

[0074] The skid body 100 is used to transport a vehicle body part 10 .

[0075] The support body 200 is disposed on the sled body 100 , and a placement portion 210 is provided on the support body 200 .

[0076] The placement portion 210 is configured to support the connecting member 20 for connecting to the vehicle body 10 and limit the position of the connecting member 20 on the support body 200 so that the first positioning portion 21 on the connecting member 20 faces a first preset direction.

[0077] In this embodiment, the skid body 100 is used to transport vehicles and may be a frame structure. The skid body 100 may be equipped with fixtures, positioning components, and the like to clamp and position the vehicle body 10, facilitating worker installation of the component onto the vehicle body 10. The skid body 100 may also be equipped with multiple drive rollers, drive belts, drive chains, and a movable platform to facilitate movement of the vehicle body 10.

[0078] The support body 200 is used to accommodate the component 20 to be connected. The component 20 to be connected is an adapter bracket and may have a first positioning portion 21 and a connecting portion. The component 20 to be connected may be in a block or rod-shaped structure. The support body 200 can be connected to the sled body 100 by screwing, welding, or clamping. A drive mechanism may also be provided between the support body 200 and the sled body 100 to adjust the position of the support body 200.

[0079] The support body 200 may be provided with a placement cavity, a first positioning portion, etc. to cooperate with the connection member 20 to position the connection member 20, so as to limit the connection member 20 to face the first preset direction. The first preset direction should be determined according to different vehicle models. For example, the first positioning portion 21 on the connection member 20 is directed to one side of the conveying direction, such as along the Figure 1 As shown in the reverse direction of the X in the middle, it is sufficient to ensure that the first positioning portion 21 can be correctly connected with the positioning component on the skid body 100. For other models, the first preset direction can be towards Figure 1 Middle X positive direction etc.

[0080] Specifically, when the skid body 100 transports the vehicle body 10 to a predetermined position, the member to be connected 20 is placed on the placement portion 210. The placement portion 210 can support the member to be connected 20 and limit the first positioning portion 21 on the member to be connected 20 to face the first preset direction, that is, the first positioning portion 21 can face one side of the transport direction, such as Figure 1 In contrast to the prior art, which lacks positioning of the member 20 to be connected and has no error-proofing structure, the embodiment of the present application facilitates the correct connection of the member 20 to be connected to the vehicle body 10 by limiting the orientation of the member 20 to be connected through the support member body 200, thereby preventing incorrect installation and ensuring that the positioning member on the skid body 100 is correctly mated with the first positioning portion 21 on the member 20 to be connected.

[0081] In some embodiments of the present application, the placement portion 210 is used to support a portion of the circumference of the component to be connected 20 and is configured to abut against a portion of the circumference of the component to be connected 20 when the component to be connected 20 is located on the placement portion 210 .

[0082] Specifically, refer to Figure 2 and Figure 3 As shown, the placement portion 210 can be a placement groove that can support the lower half of the connection member 20, or the placement groove matches the lower half of the connection member 20. In this way, when the connection member 20 is placed on the placement portion 210, on the one hand, the orientation of the connection member 20 is restricted, and on the other hand, the connection member 20 is ensured to be stably placed and not fall.

[0083] The specific shape of the placement portion 210 is determined according to the specific shape of the lower portion of the component to be connected 20 and is not specifically limited in this embodiment.

[0084] Furthermore, in some embodiments of the present application, the placement portion 210 includes a first support segment 211 and a second support segment 212 , and the first support segment 211 and the second support segment 212 are spaced apart.

[0085] The first supporting section 211 is used to support one side of the member to be connected 20 , and the second supporting section 212 is used to support the other side opposite to the member to be connected 20 .

[0086] Specifically, if Figure 2 、 Figure 3 As shown, the first support section 211 and the second support section 212 are respectively the first support block and the second support block, which are respectively connected to the two sides of the support member body 200. One side of the part to be connected 20 abuts against the first support section 211 and the other side abuts against the second support section 212, thereby ensuring the support stability of the part to be connected 20.

[0087] On this basis, in some embodiments of the present application, the first supporting section 211 has a first supporting surface 2111 , and the first supporting surface 2111 is used to match a partial arc surface 22 on one side of the component 20 to be connected.

[0088] The second supporting section 212 has a second supporting surface 2121 , and the second supporting surface 2121 is used to match with the placement plane 23 on the other side of the component 20 to be connected.

[0089] Alternatively, the first supporting surface 2111 is an inclined surface inclined toward the second supporting surface 2121 .

[0090] Specifically, refer to Figures 2 to 5 As shown, the stability of the support is ensured by abutting the first support surface 2111 on one side of the connected component 20 with the partially curved surface 22, and the placement plane 23 on the other side with the second support surface 2121. The first support surface 2111 can be either a curved surface or an inclined surface, as long as it can stably support the curved surface 22.

[0091] It should be noted that in the embodiment of the present application, the specific shapes of the first support surface 2111 and the second support surface 2121 need to be determined according to the partial arc surface 22 on one side of the connected part 20 and the placement plane 23 on the other side. Therefore, there are no excessive restrictions on the first support surface 2111 and the second support surface 2121.

[0092] In the embodiment of the present application, the placement portion 210 further includes a stopping section 213 , and the second supporting section 212 is located between the first supporting section 211 and the stopping section 213 .

[0093] The stopping section 213 is configured to limit the side surface of the to-be-connected component 20 that is away from the arc surface 22 .

[0094] Specifically, if Figure 3 As shown, the stopper section 213 can be a block-shaped, column-shaped structure, etc. The stopper section 213 and the first support section 211 are located on the same side of the support body 200. In this way, the connection member 20 can be effectively prevented from falling from the support body 200.

[0095] In addition, in the embodiment of the present application, the placement portion 210 further includes an avoidance section 214 . The avoidance section 214 is located between the first support section 211 and the second support section 212 and is used to avoid the support member body 200 .

[0096] Specifically, refer to Figure 2 and Figure 3As shown, the avoidance section 214 can be a cavity to prevent interference between the connected component 20 and the support body 200. Moreover, the approximately U-shaped structure of the avoidance section 214 can increase the support strength of the support body 200. The specific shape of the avoidance section 214 can be determined according to actual needs and is not specifically limited in this embodiment.

[0097] In order to facilitate the connection of the support body 200 to the sled body 100 , in this embodiment, a first connecting portion 220 is further provided on the support body 200 , and the first connecting portion 220 is connected to the sled body 100 .

[0098] Specifically, if Figures 2 to 5 As shown, the first connecting portion 220 can be a plate-shaped or block-shaped structure. The first connecting portion 220 is connected to the side of the first support section 211 facing away from the avoidance section 214. The first connecting portion 220 can be connected to the sled body 100 by screwing, welding, or clamping. This facilitates the installation of the support body 200 on the sled body 100.

[0099] Furthermore, in this embodiment, a driving mechanism 300 is further included, and the first connecting portion 220 is connected to the skid body 100 via the driving mechanism 300 .

[0100] The driving mechanism 300 is configured to drive the support member body 200 and the member to be connected 20 to move toward a second preset direction when the body member 10 is in a predetermined position, so that the third connecting portion 24 on the member to be connected 20 abuts against the second connecting portion 11 on the body member 10 .

[0101] Specifically, combined Figure 1 、 Figure 5 、 Figure 7 As shown, the driving mechanism 300 can be a telescopic mechanism, a manipulator, etc., which can drive the support body 200 and the connected member 20 to move toward the second preset direction, wherein the second preset direction is the direction close to or away from the second connecting portion 11, such as along Figure 1 As shown in the positive direction of X in the middle, such arrangement can facilitate the transportation of the connecting member 20 through the driving mechanism 300 and can flexibly adjust the position.

[0102] Illustratively, in this embodiment, the driving mechanism 300 includes a telescopic member 310 , a guide member 320 and a mounting seat 330 . One side of the telescopic member 310 and the guide member 320 is connected to the sled body 100 , and the other side is connected to the mounting seat 330 .

[0103] The telescopic member 310 and the guide member 320 are arranged along a second preset direction, and the first connecting portion 220 is connected to the mounting seat 330 .

[0104] Specifically, the telescopic member 310 can be a pneumatic cylinder, an oil cylinder, an electric push rod, etc. The guide member 320 can be a guide rod and rod sleeve, or a guide rail, etc. The mounting base 330 is used to mount the support body 200 and can be a plate-shaped or block-shaped structure. The mounting base 330 is connected to one side of the sled body 100 via the telescopic member 310 and the guide member 320. The specific models of the telescopic member 310, the guide member 320, and the mounting base 330 can be determined according to actual needs and are not specifically limited in this embodiment.

[0105] Furthermore, in this embodiment, at least one mounting hole 221 is provided on the first connecting portion 220 , and the mounting hole 221 is connected to the mounting seat 330 via a first fastener.

[0106] Specifically, the mounting hole 221 may be a through hole, and the first fastener may be a fastening bolt, which is passed through the mounting hole 221 and then fastened to the mounting seat 330 .

[0107] The number of the mounting holes 221 and the number of the first fasteners are the same. The specific number can be determined according to actual needs and is not specifically limited in this embodiment.

[0108] In addition, the number of the support body 200 can be two, and the two support body 200 are relatively arranged on both sides of the skid body 100 in the conveying direction, so as to respectively position the two to-be-connected parts 20 on both sides of the vehicle body part 10 .

[0109] Optionally, in this embodiment, a positioning mechanism 400 is further included, and the positioning mechanism 400 is used to connect with the second positioning portion on the vehicle body part 10 .

[0110] With this arrangement, the positioning mechanism 400 and the second positioning portion on the vehicle body member 10 can enhance the positioning of the vehicle body member 10 .

[0111] Illustratively, in this embodiment, the positioning mechanism 400 includes a positioning bracket 410 and a positioning protrusion 420 connected to the positioning bracket 410. The second positioning portion is a positioning hole matching the positioning protrusion 420. When the body part 10 is in a predetermined position, the positioning protrusion 420 is connected to the positioning hole.

[0112] In this embodiment, the positioning bracket 410 can be connected to one side of the skid body 100, and the positioning protrusion 420 can be inserted above the positioning bracket 410. When the body part 10 moves to a predetermined position, the positioning protrusion 420 can be plugged into the positioning hole on the body part 10, thereby facilitating positioning of multiple locations on the body part 10 and improving positioning accuracy.

[0113] The specific model and size of the positioning protrusion 420 and the positioning hole can be determined according to actual needs and are not specifically limited in this embodiment.
