[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] A specific embodiment of this utility model provides a side-mounted battery pack retrieval and placement gripper mechanism for new energy vehicles, combined with an attached... Figure 1 - Appendix Figure 2 As shown, it mainly includes a mounting base 1 and a gripping mechanism. The mounting base 1 is mainly used for installation, and the gripping mechanism is used to pull or push the battery pack. There are at least two gripping mechanisms, which are arranged side by side on the mounting base 1. The gripping ends of the at least two gripping mechanisms are in the same direction. In this way, when swapping batteries, two battery packs can be gripped or pushed at the same time, which greatly improves work efficiency.
[0022] In a specific embodiment of this application, the gripping mechanism includes a linear drive module 2, a module connecting plate 3, a floating connecting plate 4, a linear slider 5, a tension sensor 6, and gripping components.
[0023] The linear drive module 2 is used to achieve linear drive, and this linear drive module 2 can be a hydraulic cylinder, pneumatic cylinder, linear motor, motor-driven linear transmission mechanism, or other device capable of linear transmission. The linear drive module 2 is mounted on the mounting base 1, and the module connecting plate 3 is connected to the drive end of the linear drive module 2. The linear drive module 2 can drive the module connecting plate 3 to achieve linear movement. The floating connecting plate 4 is slidably mounted on the module connecting plate 3 via a linear slider 5. The floating connecting plate 4 is connected to a tension sensor 6, and the gripping component is mounted on the floating connecting plate 4. The linear slider 5 is in the same direction as the drive direction of the linear drive module 2. By setting the tension sensor 6, the gripping component can monitor the tension or thrust generated when gripping the battery pack, thus preventing damage to the battery pack.
[0024] In a specific embodiment of this application, the gripping component includes a fixed mounting bracket 7, a connecting rod 8, an electromagnet 9, a movable mounting bracket 10, and a spring 11.
[0025] The fixed mounting bracket 7 is mounted on the floating connecting plate 4, and can be positioned at one end of the floating connecting plate 4. The connecting rod 8 is slidably mounted on the fixed mounting bracket 7, and a sliding bushing can be provided on the fixed mounting bracket 7. The connecting rod 8 is positioned inside the sliding bushing, with its two ends located on either side of the fixed mounting bracket 7 and connected to the electromagnet 9 and the movable mounting bracket 10, respectively. One end of the electromagnet 9 is positioned as the outermost end of the gripping component, and the electromagnet 9 is used to attract the battery pack. A spring 11 is sleeved on the connecting rod 8, and its two ends abut against the movable mounting bracket 10 and the fixed mounting bracket 7, respectively. This arrangement ensures cushioning when the battery pack is pushed or pulled, thus more effectively protecting the battery pack.
[0026] Specifically, in this application, there are two of each of the connecting rod 8, electromagnet 9, and spring 11, symmetrically arranged on the fixed mounting bracket 7 and the movable mounting bracket 10. This increases both the adhesion strength with the battery pack and the contact area, thereby further protecting the battery pack.
[0027] In some embodiments, the system further includes a limiting plate 12 and a limiting bolt 13. The limiting plate 12 is disposed on the module connecting plate 3, and the limiting bolt 13 passes through the limiting plate 12 and connects to the floating connecting plate 4. The limiting bolt 13 serves as a guide and limiting device. An adjusting nut 14 is disposed on the limiting bolt 13, and the adjusting nut 14 is located between the limiting plate 12 and the floating connecting plate 4. By adjusting the distance between the adjusting nut 14 and the nut end of the limiting bolt 13, the limiting plate 12 can be displaced relative to the floating connecting plate 4. One end of the tension sensor 6 is connected to the limiting plate 12, and the other end is connected to the floating connecting plate 4. Specifically, there can be two adjusting nuts 14, located on both sides of the tension sensor 6.
[0028] In some embodiments, the gripping assembly further includes a rotary motor 15 and a pull-out hook 16. The rotary motor 15 is mounted on the floating connecting plate 4, and the pull-out hook 16 is mounted on the output end of the rotary motor 15. The pull-out hook 16 is located on one side of the electromagnet 9 and between the two connecting rods 8. The pull-out hook 16 can rotate under the drive of the rotary motor 15. When the pull-out hook 16 rotates, it can hook onto the battery pack. In this way, when pulling the battery pack, the hooking action of the pull-out hook 16 plays an auxiliary role, ensuring that the battery pack can still be taken out through the pull-out hook 16 even if the electromagnet 9 is damaged or loosened during the pulling process.
[0029] In some embodiments, the device further includes guide portions 17, which are disposed on the mounting base 1 and located on both sides of the gripping mechanism. The guide portions 17 may be strip-shaped, and two guide portions 17 serve to guide the battery pack.
[0030] In some embodiments, a visual light source 18 and a visual camera 19 are provided on the mounting base 1.
