In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The following is a more detailed description of the specific implementation of the present utility model in conjunction with specific embodiments:

[0045] like Figure 1 and Figure 2 As shown, a sled 100 provided in an embodiment of the utility model is used to be connected to the body of a vehicle, and the sled 100 is used as a fixture for carrying products, and is used to transport the body to different production workshops, such as a welding workshop, a painting workshop or an assembly workshop; in the prior art, the body is provided with a round hole or a waist-shaped hole, and the existing sled locking and unlocking mechanism 200 is locked in the round hole or the waist-shaped hole through an eccentric rotating shaft to achieve a fixed connection with the body; however, this locking method has great limitations and cannot be directly applied to a body with threaded holes, such as a battery-swap body in an electric vehicle. Since the battery-swap body itself has threaded holes, it is necessary to develop another sled locking and unlocking mechanism 200 to be suitable for the body with threaded holes, so as to reduce the limitations of the use of the sled locking and unlocking mechanism 200. The sled 100 provided in this embodiment is applied to the body before entering the electrophoresis line of the paint shop. In actual application scenarios, the sled 100 of this embodiment is not limited to the welding shop or the assembly shop. Of course, the sled 100 provided in this embodiment is not limited to the oil truck body or the electric vehicle body. As long as the body is provided with corresponding threaded holes, it should be within the application scope of the sled 100 of this embodiment. The following is an explanation through specific implementation methods:

[0046] The slide 100 includes: a slide body 1 and a threaded fastener 2; the slide body 1 is used to support the vehicle body, and the slide body 1 is provided with a connecting portion 11 for connecting with the vehicle body; the threaded fastener 2 is connected to the slide body 1, and the threaded fastener 2 is provided on the connecting portion 11, and the threaded fastener 2 is used to be threadedly connected to the threaded hole of the vehicle body, so that the vehicle body and the slide body 1 are fixedly connected.

[0047] Here, it can be understood that the sled body 1 refers to a component for carrying a vehicle body; a sled conveyor line is constructed in a vehicle production workshop, and the sled conveyor line is used to convey the sled 100 or the sled 100 carrying the vehicle body to a target station; the sled body 1 is provided with a connecting portion 11, and the connecting portion 11 refers to a component for connecting with the vehicle body. In this embodiment, the connecting portion 11 is located at both ends of the sled body 1. Of course, in actual application scenarios, the connecting portion 11 is adapted to the position of the threaded hole of the vehicle body, that is, the setting position of the connecting portion 11 is not limited;

[0048] The threaded fastener 2 refers to a component used for fastening connection with the vehicle body; specifically, the threaded fastener 2 is used for threaded connection with the threaded hole of the vehicle body. It can be understood that the hole wall of the threaded hole is provided with an internal thread, and the threaded fastener 2 is provided with an external thread matching the internal thread. In this way, the threaded fastener 2 can be screwed into the threaded hole to achieve a fixed connection with the threaded hole, thereby achieving a fixed connection between the vehicle body and the slide body 1.

[0049] The working principle of the sled 100 provided in this embodiment is as follows:

[0050] The car body is positioned and placed on the sled body 1, wherein the threaded hole of the car body is aligned with the connecting portion 11 on the sled body 1, so that the threaded fastener 2 can be screwed into the threaded hole to achieve a fixed connection between the threaded fastener 2 and the threaded hole, thereby achieving a fixed connection between the car body and the sled body 1, completing the locking of the car body and the sled 100, and the car body and the sled 100 can be transported together to the target workstation for process processing.

[0051] By adopting the above technical solution, the slide 100 can be fixedly connected to a vehicle body provided with threaded holes, thereby reducing the limitations of the use of the slide 100.

[0052] In one embodiment, the connecting portion 11 is provided with a connecting hole 12, and the threaded fastener 2 is loosely matched with the connecting hole 12. The threaded fastener 2 can extend out of the connecting hole 12 to be threadedly connected to the threaded hole of the vehicle body, so that the sled body 1 is connected to the vehicle body; the threaded fastener 2 can be retracted into the connecting hole 12 to release the connection with the threaded hole of the vehicle body, so that the sled body 1 is disconnected from the vehicle body.

[0053] Here, it can be understood that the connecting hole 12 refers to a through hole opened on the connecting portion 11; the connecting hole 12 is used to accommodate the threaded fastener 2, the threaded fastener 2 is partially or completely accommodated in the connecting hole 12, and the threaded fastener 2 is clearance-matched with the connecting hole 12, that is, the threaded fastener 2 can rotate around the axis in the connecting hole 12 and move axially relative to the connecting hole 12; when establishing the connection between the vehicle body and the sled 100, the threaded hole of the vehicle body is used to align with the connecting hole 12 of the sled 100, and the threaded fastener 2 can extend out of the connecting hole 12. At this time, the threaded fastener 2 can rotate around the axis to screw into the threaded hole, thereby realizing the fixed connection between the sled body 1 and the vehicle body; when contacting the connection between the vehicle body and the sled 100, the threaded fastener 2 is screwed out of the threaded hole, and the threaded fastener 2 is retracted into the connecting hole 12, thereby releasing the fixed connection between the sled body 1 and the vehicle body.

[0054] By adopting the above technical solution, the threaded fasteners 2 are retracted into the connection holes 12 before being connected with the threaded holes, so as to avoid being exposed outside the connection holes 12 and causing interference with the vehicle body when aligning the slide 100, thereby improving the vehicle body alignment efficiency.

[0055] Please also read Figures 3 to 5 In one embodiment, the threaded fastener 2 includes a threaded portion 21, a force-applying portion 22 connected to the threaded portion 21, and a limiting portion 23 provided between the threaded portion 21 and the force-applying portion 22.

[0056] Here, it can be understood that the threaded portion 21 refers to a component provided with threads, and the threaded portion 21 is provided with external threads. The threaded portion 21 is used to be inserted into the threaded hole and connected with the internal threads in the threaded hole; the force-applying portion 22 refers to a component used to be connected with the sled locking and unlocking mechanism 200, and the sled locking and unlocking mechanism 200 drives the force-applying portion 22 to rotate around the axis, thereby driving the threaded portion 21 to rotate around the axis, so that the threaded portion 21 is screwed into the threaded hole; in this embodiment, the force-applying portion 22 is a hexagonal head, and the connection with the force-applying portion 22 is achieved by a hexagonal wrench. Of course, in actual application scenarios, there are many ways to connect the force-applying portion 22 to the sled locking and unlocking mechanism 200; the limiting portion 23 refers to a component used to limit the connection between the threaded fastener 2 and the connecting The component of the connecting hole 12, that is, the threaded fastener 2 can rotate around the axis in the connecting hole 12, and at the same time can expand and contract relative to the connecting hole 12 within a certain range, and the threaded fastener 2 is always connected to the connecting portion 11; specifically, the connecting hole 12 is arranged through the connecting portion 11 and two openings are formed on both sides of the connecting portion 11, and the hole wall of the connecting hole 12 is provided with an annular limiting flange 121 near the opening, and the limiting flange 121 is used to limit the separation of the limiting portion 23 from the connecting hole 12, while ensuring that the threaded portion 21 and the force-applying portion 22 can extend out of the connecting hole 12; it needs to be further explained that the radial dimension of the limiting portion 23 is greater than the radial dimension of the threaded portion 21 and the force-applying portion 22, so that the limiting portion 23 can be limited in the connecting hole 12.

[0057] By adopting the above technical solution, the limiting portion 23 ensures that the threaded fastener 2 is always connected to the connecting hole 12 , which is beneficial to the connection between the threaded fastener 2 and the vehicle body, and also beneficial to the slide locking and unlocking mechanism 200 to operate the threaded fastener 2 .

[0058] In one embodiment, the connecting portion 11 is provided with a guide member 13 surrounding the connecting hole 12 , and the guide member 13 is used to guide the threaded hole of the vehicle body to align with the connecting hole 12 .

[0059] Here, it can be understood that the guide member 13 refers to a component used to guide the threaded hole of the vehicle body to align with the connecting hole 12; the guide member 13 gradually expands along the direction approaching the connecting hole 12, so that the threaded hole of the vehicle body can be gradually connected with the connecting hole 12 under the guiding action of the guide member 13.

[0060] By adopting the above technical solution, the efficiency of docking between the vehicle body and the skid 100 is improved.

When the locking mechanism 4 approaches and docks with the threaded fastener 2, the locking mechanism 4 can lock or unlock the threaded fastener 2. After the threaded fastener 2 is locked or unlocked, the locking mechanism 4 moves away from the threaded fastener 2.

[0063] By adopting the above technical solution, on the basis of having the advantages of the slide 100 of the above embodiment, the slide locking and unlocking mechanism 200 of this embodiment also has the function of locking and unlocking the threaded fastener 2 by lifting the locking mechanism 4 through the lifting mechanism 3.

The sliding drive 34 is used to drive the slide rail 33 to slide relative to the slider 32, so that the locking mechanism 4 moves in a direction close to or away from the threaded fastener 2.

[0065] Here, it can be understood that the frame 31 is used to stand on the slide conveyor line, the slider 32 is arranged on the frame 31, and the slide rail 33 is slidably connected to the slider 32, that is, the slide rail 33 can slide relative to the slider 32, the slide rail 33 is connected to the locking mechanism 4 and is used to drive the locking mechanism 4 to slide relative to the slider 32; the relative sliding direction of the slide rail 33 and the slider 32 is the direction approaching or away from the threaded fastener 2, which is the lifting direction of the locking mechanism 4 in this embodiment.
