DETAILED DESCRIPTION

[0042] The following will be combined with the attached embodiment of the utility model Figure 1-4 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making novel efforts are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0044] Combination Figure 1-Figure 4 As shown, the first aspect of the utility model provides a charging device 100 for charging a mobile device. Specifically, the mobile device may be a photovoltaic cleaning robot, or other movable device that needs to be charged.

[0045] like Figure 1 As shown, the charging device 100 includes a charging electrode 101, a power receiving electrode 102 and a rotating structure 103. The charging electrode 101 has a positive electrode and a negative electrode, and similarly, the power receiving electrode 102 also has a positive electrode and a negative electrode to achieve charging. Figure 2 As shown, the charging electrode 101 includes a positive charging electrode 101 - 1 and a negative charging electrode 101 - 2 , and the power receiving electrode 102 includes a positive power receiving electrode 102 - 1 and a negative power receiving electrode 102 - 2 .

[0046] The charging electrode 101 can be rotatably installed at the charging station through at least one rotating structure 103. Specifically, the charging electrode 101 can be arranged to be rotatable through one rotating structure 103: the positive charging electrode 101-1 in the charging electrode 101 is arranged at one end of the rotating structure 103, and the negative charging electrode 101-2 in the charging electrode 101 is arranged at the other end of the rotating structure 103; the charging electrode 101 can also be arranged to be rotatable through two rotating structures 103: the positive charging electrode 101-1 in the charging electrode 101 is arranged at one end of one rotating structure 103, and the receiving electrode 102 in the charging electrode 101 is arranged at one end of another rotating structure 103; of course, The rotation is achieved by setting three or more rotating mechanisms, taking three as an example: the first rotating structure is rotatably installed at the charging station, the second rotating structure is rotatably installed at one end of the first rotating structure, the third rotating structure is rotatably installed at the other end of the first rotating structure, the positive charging electrode 101-1 is installed at one end of the second rotating structure, and the negative charging electrode 101-2 is installed at one end of the third rotating structure. The first rotating structure ensures the simultaneous rotation of the positive charging electrode 101-1 and the negative charging electrode 101-2, the second rotating structure ensures the independent rotation of the positive charging electrode 101-1, and the third rotating structure ensures the independent rotation of the negative charging electrode 101-2.

[0047] The charging electrode 101 is used to rotate until it abuts against the power receiving electrode 102. It can be understood that the rotating structure can drive the charging electrode 101 to rotate by actively driving. For example, the rotating structure includes a rotating drive member and a rotating shaft 103-3. The rotating shaft 103-3 is installed at the power output end of the rotating drive member. The rotating drive member can drive the rotating shaft 103-3 to rotate. The charging electrode 101 is installed on the rotating shaft 103-3. The rotating drive member drives the rotating shaft 103-3 to rotate, thereby driving the charging electrode 101 to rotate. Specifically, the rotating drive member is a rotating motor or a rotating cylinder, etc. It can be understood that the rotating drive member signal is connected to the controller. By respectively arranging distance sensors near the positive charging electrode 101-1 and the negative charging electrode 101-2, the distance sensors are connected to the controller signal. The distance sensor detects the positive charging electrode 101. -1 and the positive power receiving electrode 102-1, and detects the distance between the negative charging electrode 101-2 and the negative power receiving electrode 102-2, and transmits it to the controller, and the controller controls the rotating drive member to drive the rotating shaft 103-3 to rotate; of course, the rotating structure can also drive the charging electrode 101 to rotate in a passive driving manner, that is, the rotating structure does not include a rotating drive member. When the mobile device is tilted, the positive power receiving electrode 102-1 or the negative power receiving electrode 102-2 first abuts against the positive charging electrode 101-1 or the negative charging electrode 101-2, and drives the rotating structure to rotate, and finally the positive charging electrode 101-1 abuts against the positive power receiving electrode 102-1, and the negative charging electrode 101-2 abuts against the negative power receiving electrode 102-2, thereby realizing docking charging.

[0048] Similarly, the power receiving electrode 102 can be rotatably mounted on the mobile device through at least one rotating structure 103. Specifically, the power receiving electrode 102 can be rotatably mounted through one rotating structure 103: the positive power receiving electrode 102-1 in the power receiving electrode 102 is arranged at one end of the rotating structure 103, and the negative power receiving electrode 102-2 in the power receiving electrode 102 is arranged at the other end of the rotating structure 103; the power receiving electrode 102 can also be rotatably mounted through two rotating structures 103: the positive power receiving electrode 102 in the power receiving electrode 102 is arranged at one end of one rotating structure 103, and the negative power receiving electrode 102 in the power receiving electrode 102 is arranged at one end of another rotating structure 103. end; of course, three or more rotating mechanisms can be set to achieve rotation. Take three as an example: the first rotating structure can be rotatably installed on the mobile device, the second rotating structure can be rotatably installed at one end of the first rotating structure, and the third rotating structure can be rotatably installed at the other end of the first rotating structure. The positive power receiving electrode 102 is installed at one end of the second rotating structure, and the negative power receiving electrode 102 is installed at one end of the third rotating structure. The first rotating structure ensures the simultaneous rotation of the positive power receiving electrode 102 and the negative power receiving electrode 102, the second rotating structure ensures the independent rotation of the positive power receiving electrode 102, and the third rotating structure ensures the independent rotation of the negative power receiving electrode 102.

[0049] The power receiving electrode 102 is used to rotate until it abuts against the charging electrode 101. It can be understood that the rotating structure can drive the charging electrode 101 to rotate by actively driving. For example, the rotating structure includes a rotating drive member and a rotating shaft 103-3. The rotating shaft 103-3 is installed at the power output end of the rotating drive member. The rotating drive member can drive the rotating shaft 103-3 to rotate. The power receiving electrode 102 is installed on the rotating shaft 103-3. The rotating drive member drives the rotating shaft 103-3 to rotate, thereby driving the power receiving electrode 102 to rotate. Specifically, the rotating drive member is a rotating motor or a rotating cylinder, etc. It can be understood that the rotating drive member signal is connected to the controller. By respectively arranging distance sensors near the positive power receiving electrode 102-1 and the negative power receiving electrode 102-2, the distance sensors are connected to the controller signal. The distance sensor detects the positive charging electrode 101. -1 and the positive power receiving electrode 102-1, and detects the distance between the negative charging electrode 101-2 and the negative power receiving electrode 102-2, and transmits it to the controller, and the controller controls the rotating drive member to drive the rotating shaft 103-3 to rotate; of course, the rotating structure can also drive the charging electrode 101 to rotate in a passive driving manner, that is, the rotating structure does not include a rotating drive member. When the mobile device is tilted, the positive power receiving electrode 102-1 or the negative power receiving electrode 102-2 first abuts against the positive charging electrode 101-1 or the negative charging electrode 101-2, and drives the rotating structure to rotate, and finally the positive charging electrode 101-1 abuts against the positive power receiving electrode 102-1, and the negative charging electrode 101-2 abuts against the negative power receiving electrode 102-2, thereby realizing docking charging.

[0050] In the charging device 100 provided by the present invention, since at least one of the charging electrode 101 and the power receiving electrode 102 can rotate, when the mobile device is charged, even if it is deflected, the power receiving electrode 102 and / or the charging electrode 101 can be rotated under the action of the rotating structure to achieve the docking of the power receiving electrode 102 with the charging electrode 101. That is, the charging device 100 provided by the present invention improves the docking accuracy of the charging electrode 101 and the power receiving electrode 102.

[0051] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the charging electrode 101 and the power receiving electrode 102 are both arranged in a strip shape, and when the charging electrode 101 and the power receiving electrode 102 are docked, the charging electrode 101 and the power receiving electrode 102 are arranged vertically or obliquely. It can be understood that the charging electrode 101 and the power receiving electrode 102 are both arranged in a strip shape, which means that the charging end of the charging electrode 101 and the power receiving end of the power receiving electrode 102 have a certain length, so that when a certain error or misalignment occurs along the height direction or horizontal direction of the mobile device, the power receiving electrode 102 and the charging electrode 101 can still achieve docking and charging.

[0052] like Figure 1 and Figure 2 As shown, the charging electrode 101 is arranged vertically, and the receiving electrode 102 is arranged horizontally. It should be noted that the charging electrode 101 may be arranged horizontally, and the receiving electrode 102 may be arranged vertically; or, the charging electrode 101 and the receiving electrode 102 may be arranged obliquely.

[0053] In one embodiment of the utility model, the rotating structure 103 includes a base 103-1 and a rotating member 103-2, wherein the base 103-1 is used to be installed on a charging station or a mobile device. Specifically, the base 103-1 can be detachably installed on the charging station or the mobile device by fasteners such as bolts.

[0054] The rotating member 103-2 is rotatably mounted on the base 103-1 via the rotating shaft 103-3. The rotating shaft 103-3 is parallel to or inclined with the height direction of the mobile device to realize the horizontal rotation of the rotating member 103-2, thereby adapting to the docking of the receiving electrode 102 and the charging electrode 101 when the mobile device is tilted.

[0055] The positive charging electrode 101-1 is installed at one end of the rotating member 103-2, and the negative charging electrode 101-2 is installed at the other end of the rotating member 103-2; or the positive receiving electrode 102-1 is installed at one end of the rotating member 103-2, and the negative receiving electrode 102-2 is installed at the other end of the rotating member 103-2. In this embodiment, the rotating structure 103 is installed at a charging station as an example. Figure 2 As shown, at this time, the positive charging electrode 101-1 is installed at one end of the rotating member 103-2, and the negative charging electrode 101-2 is installed at the other end of the rotating member 103-2. The positive power receiving electrode 102-1 first contacts the positive charging electrode 101-1, thereby pushing the rotating member 103-2 to rotate, thereby realizing the contact between the negative power receiving electrode 102-2 and the negative charging electrode 101-2, and completing the docking; or, the negative power receiving electrode 102-2 first contacts the negative charging electrode 101-2, thereby pushing the rotating member 103-2 to rotate, thereby realizing the contact between the positive power receiving electrode 102-1 and the positive charging electrode 101-1, and completing the docking.

[0056] In order to prevent the rotating member 103-2 from rotating at an excessively large angle, an embodiment of the utility model discloses that a limit member is provided on the base 103-1, wherein the limit member is used to limit the rotation angle of the rotating member 103-2. Specifically, the limit member may include a first rotation limit plate and a second rotation limit plate respectively provided on both sides of the base 103-1, wherein the first rotation limit plate and the second rotation limit plate are respectively limited by abutting against the rotating member 103-2.

[0057] In order to reduce the number of parts required for the charging device 100, an embodiment of the utility model discloses that the base 103-1 is C-shaped, that is, the base 103-1 has a C-shaped groove, such as Figure 3 As shown, the rotating member 103-2 is placed in the C-shaped groove of the base 103-1. When the rotating member 103-2 rotates, it will abut against the two sides of the vertical wall of the C-shaped groove to achieve limiting. In other words, the vertical wall is the limiting member.

[0058] In order to reduce the weight of the rotating member 103-2, an embodiment of the utility model discloses that the rotating member 103-2 is a metal plate, wherein a first folded convex edge and a second folded convex edge are provided at the middle position of the metal plate, the first folded convex edge abuts against the top wall of the C-shaped groove, the second folded convex edge abuts against the bottom wall of the C-shaped groove, and the rotating shaft 103-3 passes through the top wall of the C-shaped groove, the first folded convex edge, the second folded convex edge and the bottom wall of the C-shaped groove. Specifically, the rotating shaft 103-3 can be a pin or the like.

[0059] It should be noted that the above-disclosed structure of the rotating member 103 - 2 is only a specific implementation of the present invention. In actual applications, the rotating member 103 - 2 can also be set as a frame structure, etc.

[0060] In one embodiment of the present invention, Figure 4 As shown, the charging device 100 further includes a mounting housing 104 disposed on a charging station or a mobile device. When the charging electrode 101 or the power receiving electrode 102 is connected to the rotating structure 103, the rotating structure 103 is mounted in the mounting housing 104, and a avoidance hole 104a is provided on the mounting housing 104 to allow the charging electrode 101 or the power receiving electrode 102 to pass through. The provision of the mounting housing 104 achieves effective protection of the rotating structure 103 and beautifies the appearance.

[0061] In one embodiment of the utility model, the charging device 100 further includes a sliding structure 105. Along the docking direction of the charging electrode 101 and the power receiving electrode 102, the charging electrode 101 can be slidably installed at the charging station through at least one sliding structure 105. The sliding structure 105 enables the charging electrode 101 to slide along the docking direction with the power receiving electrode 102, thereby solving the docking problem caused by the deviation of the mobile device along the docking direction of the charging electrode 101 and the power receiving electrode 102.

[0062] Of course, it can also be set separately or simultaneously: along the docking direction of the charging electrode 101 and the power receiving electrode 102, the power receiving electrode 102 can be slidably installed on the mobile device through at least one sliding structure 105. The sliding structure 105 enables the charging electrode 101 to slide along the docking direction with the power receiving electrode 102, solving the docking problem caused by the deviation of the mobile device along the docking direction of the charging electrode 101 and the power receiving electrode 102.

[0063] It should be noted that the sliding structure 105 can slide by being driven by a sliding driving member, or can slide under the action of an external force.

[0064] In one embodiment of the present utility model, Figure 2 and Figure 3 As shown, the sliding structure 105 includes a mounting member 105-1 and an elastic reset member 105-3. For example, the power receiving electrode 102 is mounted on the sliding structure 105. Specifically, the power receiving electrode 102 is mounted on the mounting member 105-1. One of the mounting member 105-1 and the moving device is provided with a sliding groove 105-1a, and the other is provided with a sliding member 105-2 which is slidably connected to the sliding groove 105-1a. Figure 1 As shown, taking the example of a sliding member 105-2 installed on the chassis 200 of the mobile device and a slide groove 105-1a being provided on the mounting member 105-1, an elastic reset member 105-3 is installed on the mobile device, and one end thereof is abutted or connected to the mounting member 105-1. When the power receiving electrode 102 abuts against the charging electrode 101, the charging electrode 101 squeezes the elastic reset member 105-3, so that the mounting member 105-1 drives the power receiving electrode 102 to slide, so that even if the parking position of the mobile device along the docking direction of the power receiving electrode 102 and the charging electrode 101 deviates, the docking of the charging electrode 101 and the power receiving electrode 102 can still be achieved.

[0065] When the charging electrode 101 is mounted on the sliding structure 105, the charging electrode 101 is mounted on the mounting member 105-1. One of the mounting member 105-1 and the charging station is provided with a slide groove 105-1a, and the other is provided with a sliding member 105-2 that is slidably connected to the slide groove 105-1a. The sliding structure 105 slides by the cooperation of the sliding member 105-2 and the slide groove 105-1a.

[0066] Specifically, the elastic return member 105 - 3 is a spring or the like.

[0067] In order to facilitate the installation of the elastic reset member 105-3, an embodiment of the utility model discloses that the sliding structure 105 also includes a reset member mounting seat 105-4, and the reset member mounting seat 105-4 is connected to the charging station or the mobile device. In this embodiment, the sliding structure 105 is installed on the mobile device, such as Figure 2 As shown in the example, a receiving hole for receiving the elastic return member 105 - 3 is provided on the return member mounting seat 105 - 4 , so as to facilitate the installation of the elastic return member 105 - 3 .

[0068] In one embodiment of the utility model, a first deviation value X of the mobile device is allowed along the docking direction of the charging electrode 101 and the power receiving electrode 102, that is, the length direction of the mobile device: X<0.5L, where L is the spacing value between the positive charging electrode 101-1 and the negative charging electrode 101-2. And L+X<d, where d is the width of the mobile device, to avoid the situation where the positive charging electrode 101-1 and the positive power receiving electrode 102-1 are completely misaligned, and the negative charging electrode 101-2 and the negative power receiving electrode 102-2 are completely misaligned when the charging electrode 101 and the power receiving electrode 102 are docked.

[0069] The second deviation value of the mobile device is allowed to be less than 12 mm along the docking direction of the charging electrode 101 and the receiving electrode 102. It should be noted that the value is not limited to the above range and can be set arbitrarily within the allowable range of the chassis 200 of the mobile device.

[0070] The allowable deflection angle of the mobile device is greater than or equal to -15° and less than or equal to +15°. It can be understood that the positive and negative values ​​of the angle here refer to the deflection angle along the top view of the mobile device, the clockwise deflection is positive, and the counterclockwise deflection is negative; of course, it can also be set that along the top view of the mobile device, the clockwise deflection is negative and the counterclockwise deflection is positive.

[0071] like Figure 4 As shown, in one embodiment of the present invention, the sliding structure 105 is installed on the mobile device, and the rotating structure 103 is installed at the charging station, which is convenient for the installation of the power receiving electrode 102 and the charging electrode 101.
