[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] The utility model provides a retractable conductive signal collection contact device, which is used for signal collection and transmission during the docking charging process of AGV logistics vehicle lithium battery and other lithium battery charging devices. Since the contact adopts a rotatable and retractable function, it ensures reliable contact with the power receiving bar in the charging vehicle plug, so that stable current conduction transmission can be carried out during the docking charging process to ensure the reliability of charging. The insulating shell meets the electrical technical requirements such as insulation withstand voltage.

[0021] See also Figures 1 to 7 The utility model provides a retractable conductive signal collection contact device, which has the function of retractable adaptive flexible contact and conduction, and includes an insulating shell 1, a support seat 2, a fixing seat 3, a pin 4, a connecting arm 5, a conductive contact 6 and a support spring 7;

[0022] The insulating shell 1 is a cavity structure with an opening at the top; a support seat 2 is fixedly installed inside the insulating shell 1; a fixing seat 3 is fixedly installed on the side of the support seat 2; a pin shaft 4 is fixedly installed inside the fixing seat 3; one end of a connecting arm 5 is sleeved on the outside of the pin shaft 4, and the other end of the connecting arm 5 is hinged to the conductive contact 6, so that the conductive contact 6 can rotate relative to the pin shaft 4; a supporting spring 7 is installed between the bottom of the conductive contact 6 and the support seat 2; during the specific installation, the bottom of the supporting spring 7 can be fixed to the support seat 2, and the top can be embedded in the limiting groove opened at the bottom of the conductive contact 6.

[0023] The upper surface of the conductive contact 6 is an arc-shaped surface for contacting the power receiving bar. When no external force is applied, the supporting spring 7 supports the conductive contact 6 so that the top of the conductive contact 6 is higher than the cavity of the insulating housing 1.

[0024] Furthermore, bolt mounting seats 1 - 1 are respectively provided on both sides of the insulating housing 1 ; connecting bolts 8 are installed in the bolt mounting seats 1 - 1 ; and flexible conductive connecting members 9 are provided between the tops of the connecting bolts 8 and the conductive contacts 6 .

[0025] The utility model provides a retractable conductive signal collection contact device, and a specific use method is as follows:

[0026] like Figure 6 As shown, a mounting plate 11 can be installed at the bottom of the insulating housing 1, and the entire contact device is assembled into the charging pile socket through the mounting plate 11; when the charging pile socket is not inserted into the power receiving bar, the contact device is Figure 6In the state shown, the conductive contact 6 pops out under the action of the supporting spring 7; when the receiving bus is inserted into the charging pile socket, the receiving bus squeezes the conductive contact 6, causing the conductive contact 6 to overcome the force of the supporting spring 7 and rotate to Figure 7 In the state shown, at the same time, the support spring 7 still applies a force to the conductive contact 6 to rotate toward the power receiving bar. Under the dual action of the support spring 7 and the power receiving bar, the surface of the power receiving bar and the conductive contact 6 are reliably contacted, thereby realizing reliable collection of the CP signal.

[0027] In the present application, since the conductive contact 6 can be rotated and retracted, a flexible conductive connector 9 is correspondingly designed in the present application. By installing the flexible conductive connector 9, the conductive contact 6 can be rotated freely without restricting the rotation of the conductive contact 6. As a specific method, a conductive connector 10 is installed at the bottom of the connecting bolt 8. The electrical signal collected by the conductive contact 6 is first transmitted to the flexible conductive connector 9, then to the connecting bolt 8, and finally to the conductive connector 10. The conductive connector 10 is connected with other collection and storage devices to realize the transmission of electrical signals.

[0028] Therefore, the retractable conductive signal collection contact is installed on the corresponding charging connection mechanism, so that the conductive signal collection contact is combined with a charging mechanism, so that the power receiving device can be flexibly connected to the conductive signal collection contact, and the stable contact between the power receiving bus and the contact can be ensured for current transmission.

[0029] In the utility model, the support spring 7 is designed on the support seat 2 in the insulating housing 1, which can ensure the adaptive expansion and contraction of the conductive contact 6 and has a buffering effect to ensure the stable contact between the power receiving bus and the conductive contact 6.

[0030] The utility model provides a retractable conductive signal collection contact device, which has the function of retractable flexible conductivity, which can not only ensure the overall appearance, integration, concealment, adaptability, conductivity, structural firmness, but also ensure insulation and safety during operation. Since the contact adopts a rotatable and retractable function, it can ensure reliable contact with the power receiving bar in the charging vehicle plug, so that stable current conduction transmission can be carried out during the docking charging process, ensuring the reliability of charging.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention.
