[0002] AGV, short for Automated Guided Vehicle, is an unmanned transport vehicle that combines charging contacts, a charging device, and an AGV with automatic navigation, handling, positioning, and obstacle avoidance capabilities. AGVs typically use laser, visual, and electromagnetic navigation methods, enabling them to navigate autonomously in complex environments and complete various transport tasks. AGVs are widely used in logistics, manufacturing, healthcare, and other fields. However, the operation of AGVs relies on various sensors and electrical components, of which the contact pad is a key component for electrical connection and signal transmission.

[0003] In existing technologies, touch panels typically employ a relatively simple planar structure, resulting in a relatively simple contact method between them and the corresponding contact components. Charging between the touch panels and the contact components requires a level surface. However, on tilted surfaces, the influence of gravity and vehicle motion can easily lead to poor contact between the contacts and the contact components, compromising safety and stability.

For example, A and / or B can mean: A exists alone, A and B exist simultaneously, or multiple situations exist.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0032] The following is combined with Figures 1 to 7 The present invention is described in further detail, but is not intended to limit the present invention.

[0033] like Figure 1 and 2As shown, in one embodiment of the present invention, the charging contact comprises an insulating base 1, a wiring harness 5, a contact component 2, a movable component 3, and a mounting housing 4; the mounting housing 4 is connected to the insulating base 1; a mounting cavity 41 is provided between the mounting housing 4 and the insulating base 1; the movable component 3 is disposed within the mounting cavity 41; and the contact component 2 is connected to one end of the movable component 3 so that the contact component 2 moves toward or away from the mounting cavity 41; one end of the wiring harness 5 passes through the insulating base 1 and is connected to the contact component 2; and a mounting gap 42 is provided between the contact component 2 and the mounting housing 4; the mounting gap 42 is connected to the mounting cavity 41. In some embodiments, there are two contact components 2, one for the positive electrode and the other for the negative electrode. Furthermore, the number of wiring harnesses 5, movable components 3, and mounting housings 4 corresponds to the number of contact components 2.

[0034] The technical solution of the present invention can promote the convenience and flexibility of contact charging of the contact component through the reciprocating performance of the movable component, and by adding an installation gap between the contact component and the mounting shell during the assembly process, it can effectively avoid poor contact between the contact component and the charging contact plate; thereby effectively avoiding a series of problems such as excessive temperature rise and signal transmission errors caused by unstable current transmission; thereby improving the stability and safety of use.

[0035] Wherein, in some embodiments, Figure 2 As shown, the insulating base 1 is provided with at least one first positioning hole 11, which is set through the thickness of the insulating base 1. Furthermore, the number of the first positioning holes 11 is at least three, and they are used for assembly with the AGV vehicle.

[0036] Specifically, in some embodiments, the size L0 of the installation gap 42 satisfies the following: 1.00 mm ≤ L0 ≤ 1.11 mm. L0 can be 1.00 mm, 1.03 mm, 1.05 mm, 1.08 mm, 1.11 mm, etc., preferably 1.05 mm. This structure increases the size of the installation gap 42 to meet the requirement of 1.00 mm ≤ L0 ≤ 1.11 mm, thereby enabling the contact component 2 to meet ±5° operating conditions under different annular tilts, thereby improving operational stability and safety.

[0037] Specifically, in some embodiments, Figure 1 and 2As shown, the installation gap 42 includes a horizontal gap 421 and a longitudinal gap 422. The longitudinal gap 422 is provided at both ends of the length direction (X-axis) of the contact component 2 (i.e., at the upper and lower ends). The horizontal gap 421 is provided at both ends of the height direction (Z-axis) of the contact component 2 (i.e., at the left and right ends). The relationship between the dimension L1 of the horizontal gap 421 and the dimension L2 of the longitudinal gap 422 satisfies the following conditions: L1 < L2. That is, 1.00mm≤L1<1.11mm, and 1.00mm≤L2<1.11mm, and L1 < L2. In other words, by increasing and adjusting the dimensions of the horizontal gap 421 and the longitudinal gap 422 simultaneously, and by making the dimension of the horizontal gap 421 slightly smaller (since most of the tilting process will tilt to the left or right), the device can be controlled to adapt to a working environment that can meet ±5° in the vertical direction, thereby improving stability and safety in use.

[0038] Specifically, in some embodiments, Figure 2 and 3 As shown, the movable component 3 is a compression spring 31; one end of the compression spring 31 is connected to the insulating base 1; the other end of the compression spring 31 passes through the mounting cavity 41 and is connected to the contact component 2. This structure improves the convenience and flexibility of contact charging of the contact component through the compression movement and automatic recovery performance of the compression spring 31.

[0039] Specifically, in some embodiments, Figure 1 and 3 As shown, when the extrusion spring 31 is in a non-extrusion state, the angle α between the vertical plane formed in the vertical direction of the installation cavity 41 and the contact component 2 satisfies: 3.89°≤α≤6.56°. α can be 3.89°, 4.15°, 5.17°, 6.26°, 6.56°, etc. It is preferably 6.26°. When the extrusion spring 31 is in an extrusion state (and extruded to the extreme position), the angle β between the vertical plane formed in the vertical direction of the installation cavity 41 and the contact component 2 satisfies: 1.37°≤β≤5.13°. α can be 1.37°, 4.15°, 5.17°, 5.03°, 5.13°, etc. It is preferably 5.03°. In the natural state, the angles of the left and right sides in the vertical direction increase to 3.89°~6.56°; when the upper part is compressed to the bottom, the angles of the left and right sides in the vertical direction increase to 1.37°~5.13°; thus, the AGV contacts can meet the working conditions of ±5° in the vertical direction, thereby improving the safety and stability of use.

[0040] Specifically, in some embodiments, Figure 1 and 4As shown, the contact component 2 is provided with an assembly cavity 22 on one side facing the wiring harness body 5; a first conductive connector 21 is provided within the assembly cavity 22; and a second conductive connector 51 is provided on the other side facing the contact component 2. The second conductive connector 51 can penetrate the assembly cavity 22 and connect to the first conductive connector 21. The first conductive connector 21 is a metal conductive connector with a U-shaped cross-section. This structure improves the stability and convenience of the assembly and electrical connection between the wiring harness body 5 and the contact component 2, ensuring safety in use and avoiding situations such as interruption of the charging signal.

[0041] Specifically, in some embodiments, Figure 4 and 5 As shown, the second conductive connector 51 includes a stopper section 511 and a clamping section 512, which are interconnected. The clamping section 512 is detachably connected to (and clamped to) the inner wall of the first conductive connector 21. The outer wall of the stopper section 511 is in close contact with the inner wall of the assembly cavity 22. The stopper section 511 is also connected to the main body of the wiring harness 5. This structure, through the detachable assembly of the clamping section 512 and the reinforced assembly of the stopper section 511, ensures the stability and security of signal transmission during the compression, contraction, and recovery of the contact component 2.

[0042] Specifically, in some embodiments, Figure 5 As shown, the wiring harness body 5 includes a sleeve 501, a wire 502 and a terminal 503; the sleeve 501 is sleeved on the outer surface of the wire 502; one end of the wire 502 is connected to the second conductive connector 51 (limiting section 511); the other end of the wire 502 is connected to the terminal 503. Figure 5 As shown, an assembly gap 513 is defined between one end of the sleeve 501 facing the limiting section 511 and the limiting section 511. This assembly gap 513 allows for adaptive adjustment of the wire 502 during the extrusion of the contact component 2, thereby reducing the deformation speed of the wire 502 and improving the stability and safety of signal transmission.

[0043] The present invention also provides a charging device, such as Figure 5 and 6As shown, the charging device includes a charging contact and a charging connector 600. The charging connector 600 includes an insulating support 610, a conductive component 620, and a conductive contact plate 630. The conductive contact plate 630 is connected to a side surface (connection groove) of the insulating support 610. The conductive component 620 passes through the insulating support 610 and connects to the conductive contact plate 630. The conductive contact plate 630 can abut against the contact component. The specific structure of the charging contact refers to the above-mentioned embodiments. Since this charging device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be detailed here.

[0044] Wherein, in some embodiments, Figure 4 and 5 As shown, there are two conductive contact pads 630, symmetrically arranged on the insulating support 610. The insulating support 610 is provided with at least one second positioning hole 611 for assembly with the charging host. The insulating support 610 is also provided with at least one separating heat dissipation slot 612, which is disposed between the two conductive contact pads 630. This structure, through the recessed design of the separating heat dissipation slot 612, increases the amount of heat dissipation airflow, thereby improving heat dissipation efficiency.

[0045] Specifically, in some embodiments, Figure 6 and 7 As shown, the conductive assembly 620 includes a conductive block 621, a screw 622 and a bolt 623; the conductive block 621 is disposed inside the insulating support 610 and abuts against the bottom of the conductive contact plate 630; the screw 622 passes through the conductive contact plate 630 and the conductive block 621, and is threadedly connected to the conductive contact plate 630 and the bolt 623 respectively. Figure 7 As shown, the conductive assembly 620 includes a gasket 624 and a protective cover 625; the gasket 624 is disposed between the bolt 623 and the conductive block 621; the protective cover 625 is sleeved on the bolt 623. Furthermore, the gasket 624 includes a flat washer and a spring washer.

[0046] The present invention also provides an AGV, comprising a vehicle body and a charging device. The charging contacts are connected to the vehicle body; the charging connector is mounted on a charging surface. The specific structure of the charging contacts and the charging device are similar to those in the above-mentioned embodiments. Since this charging device utilizes all the technical solutions of all of the above-mentioned embodiments, it possesses at least all the beneficial effects of the technical solutions of the above-mentioned embodiments, and therefore will not be further elaborated here.
