Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a circuit connection structure and a window cleaning robot base station comprising the circuit connection structure. Background Art

[0002] The window cleaning robot base station is usually equipped with a cable retracting device to retract and release the cable, which can be used to connect the window cleaning robot and power it. The cable retracting device usually includes a rotatable turntable, one end of the cable passes through the turntable and is connected to the power supply, and the power supply supplies power to the window cleaning robot through the cable. However, since the end of the cable is fixed outside the turntable, it is easily driven by the turntable when it rotates and twists, causing the cable to be damaged. Utility Model Content

[0003] One of the purposes of the utility model is to provide a circuit connection structure which can prevent the cable from twisting when the turntable rotates, thereby reducing the damage to the cable.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a circuit connection structure, including a conductive disk and a conductive contact for respectively connecting two components to be electrically connected, wherein the conductive disk is configured to be able to move relative to the conductive contact, and the conductive contact is configured to always maintain abutment with the conductive disk and a fixed position when the conductive disk moves relative to the conductive contact.

[0005] Furthermore, the conductive contact is connected to an elastic member, the position of the elastic member is fixed and is configured to be able to be elastically deformed when the conductive contact abuts against the conductive disk, so that the conductive contact is close to the conductive disk.

[0006] Furthermore, the elastic member is a V-shaped spring piece, and a conductive contact is respectively provided at both ends of the V-shaped spring piece.

[0007] Furthermore, the number of the conductive plates corresponds to the number of electrical polarities of the components to be electrically connected to them.

[0008] Furthermore, the electrical polarity of the component to be electrically connected to which the conductive disk is connected includes a positive electrode and a negative electrode, and the number of the conductive disks is two and they are insulated and connected or spaced apart.

[0009] Furthermore, the conductive disk is ring-shaped and can rotate relative to the conductive contact.

[0010] Another object of the utility model is to provide a window cleaning robot base station, which includes the circuit connection structure described above.

[0011] The utility model has a simple structure, and the electrical connection between the two parts to be electrically connected can be achieved through the abutment between the conductive disk and the conductive contact. Moreover, the conductive disk can move relative to the conductive contact, and the position of the conductive contact is fixed. When it is applied to a turntable for reeling and reeling the line, the conductive disk can be fixed on the turntable, one end of the cable is connected to the conductive disk, and the conductive contact is connected to an external power supply. When the turntable rotates, the conductive disk and the cable connected to the conductive disk can keep rotating synchronously with the turntable, and the conductive contact always keeps in abutment with the conductive disk and the position remains unchanged, so that when the cable is energized, the cable can be prevented from being twisted and damaged.

[0022] In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "back", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. The term "plurality" means more than two (including two).

[0023] In order to help those skilled in the art to more clearly understand the concept of the present invention, the present invention is further described below in conjunction with embodiments and drawings. Example 1

[0024] The present embodiment provides a circuit connection structure, which mainly includes a conductive plate 1 and a conductive contact 2 that are in contact with each other, and the conductive plate 1 and the conductive contact 2 are respectively used to connect two components to be electrically connected. The two components to be electrically connected can be a cable and a power supply, the cable is used to connect the device to be powered on, and the power supply is used to supply power; or they can be two cables, one cable is used to connect the device to be powered on, and the other cable is used to connect the power supply. The following takes the two components to be electrically connected as a cable and a power supply as an example for explanation. The above-mentioned circuit connection structure is arranged between the cable and the power supply to realize the electrical connection between the cable and the power supply, so that the power supply and the cable are conductive, and then the device connected to the cable is powered.

[0025] Figure 4-6 The specific structure of the circuit connection structure is shown, which mainly includes a conductive disk 1 and a conductive contact 2. The conductive contact 2 is arranged below the conductive disk 1 and abuts against it. The conductive disk 1 can move relative to the conductive contact 2. The conductive contact 2 can always abut against the conductive disk 1 and keep its position fixed when the conductive disk 1 moves relative to it. The conductive disk 1 and the conductive contact 2 are connected to the cable and the power supply respectively. In this embodiment, the electrical connection between the cable and the power supply can be achieved through the abutting conductive disk 1 and the conductive contact 2, and when the cable is retracted and released through the turntable, the cable can be twisted and damaged.

[0026] The following is an example of the cable being retracted and released through a turntable. The conductive disk 1 is installed on the turntable 6, and the cable 5 connected to the turntable 6 is connected to the conductive disk 1, so that the conductive disk 1 and the cable 5 can rotate synchronously with the turntable 6. Moreover, the position of the conductive contact 2 remains unchanged, which is equivalent to that the conductive disk 1 can rotate relative to the conductive contact 2. Among them, the number of conductive disks 1 corresponds to the number of electrical polarities of the cable 5. For example, if the cable 5 includes three conductive wires, and the electrical polarities of these conductive wires are positive, negative, and ground, then the number of conductive disks 1 is three; if the cable 5 includes two conductive wires, and the electrical polarities of these conductive wires are positive and negative, then the number of conductive disks 1 is two. In this embodiment, the number of conductive disks 1 is two and they are respectively connected to the positive conductive wire and the negative conductive wire in the cable 5. The two conductive disks 1 are insulated or spaced to avoid electrical connection between the two. For example, the turntable 6 is made of insulating material, the conductive disk 1 is annular and coaxially arranged with the turntable, and the two conductive disks 1 are of different sizes and spaced, so that these conductive disks 1 can be spaced apart to avoid contact between them. The conductive contacts 2 are arranged below the conductive disks 1, and these conductive contacts 2 correspond one-to-one to the electrical polarities of the conductive disks 1. Each conductive disk 1 is used to connect a conductive wire in a cable 5, and each conductive disk 1 corresponds to the electrical polarity of the connected conductive wire.

[0027] In this embodiment, the conductive contact 2 is connected to an elastic member 3 (the elastic member 3 can be arranged at the other end of the conductive contact 2 abutting against the conductive disk 1, that is, the end of the conductive contact 2 away from the conductive disk 1, for example, the lower end of the conductive contact 2), and the position of the elastic member 3 is fixed and can be elastically deformed when the conductive contact 2 abuts against the conductive disk 1. Through the elastic force of the elastic member 3, the conductive contact 2 can be urged to be close to the conductive disk 1, so that when the conductive disk 1 rotates with the rotating disk 6, the conductive contact 2 and the conductive disk 1 can maintain good contact. Moreover, in order to further ensure the contact reliability between the conductive contact 2 and the conductive disk 1, the elastic member 3 can also be set as a V-shaped spring sheet, and a conductive contact 2 is arranged at each end of the V-shaped spring sheet. In this way, the conductive contacts 2 at both ends of each V-shaped spring sheet can form a group, and the two conductive contacts 2 in each group have the same electrical polarity. Each conductive disk 1 can contact the two conductive contacts 2 in each group. Then, even if one of the conductive contacts 2 is separated from the conductive disk 1, there is still another conductive contact 2 in contact with it, and the reliability is higher.

[0028] The above-mentioned circuit connection structure is simple and has low cost. It can realize the electrical connection between the two components to be electrically connected through the abutment between the conductive disk 1 and the conductive contact 2. When it is applied to the turntable 6 for reeling and releasing the wire, the conductive disk 1 is fixed on the turntable 6, one end of the cable 5 is connected to the conductive disk 1, and the conductive contact 2 is externally connected to the power supply. When the turntable 6 rotates, the conductive disk 1 and the cable 5 connected to the conductive disk 1 can keep rotating synchronously with the turntable 6, and the conductive contact 2 always keeps in abutment with the conductive disk 1 and is fixed. In this way, when the cable 5 is energized, the cable 5 can be prevented from twisting and being damaged. Example 2

[0029] This embodiment provides a window cleaning robot base station, which includes a base station body 4 and a circuit connection structure of embodiment 1. The specific structure can be seen in Figure 1-6 . The base station body 4 is provided with a turntable 6 and a cable 5, as well as an installation groove 4a which can accommodate the window cleaning robot and has a shape equivalent thereto. The window cleaning robot can be placed in the installation groove 4a for storage, and the cable 5 is retracted and released through the turntable 6. A top cover 7 is also provided on the base station body 4. Among them, the window cleaning robot includes but is not limited to two cleaning turntables. In addition, the structure and working principle of the window cleaning robot are prior art and will not be repeated here. Among them, the cable 5 may include a composite rope for connecting the window cleaning robot and a power cord for powering the base station. The composite rope is mainly used to prevent the window cleaning robot from falling from the window when working. It has a conductive wire (such as a positive and negative conductive wire) built in it, and the composite rope is retracted and released through one of the turntables 6. The power cord is mainly used to power the base station, and then power the window cleaning robot through the base station. It also has a conductive wire (such as a positive and negative conductive wire) built in it, and is retracted and released through another turntable 6. The power cord can be set to be longer, so that even if the base station is far away from the socket, it can still be powered.

[0030] In this embodiment, the composite rope is retracted and released through the turntable 6, and two conductive disks 1 are installed on the turntable 6. Each conductive disk 1 is connected to the positive and negative conductive wires in the composite rope. For example, a terminal is set on the conductive disk 1, and the conductive wire is connected to the terminal. The conductive contact 2 is fixed on the base station body 4. For example, a V-shaped spring is set on the base station body 4, and the conductive contact 2 is set on the V-shaped spring. The V-shaped spring can be connected to the power supply (or a cable connected to the power supply). When the turntable 6 retracts and releases the composite rope, the position of the conductive contact 2 remains unchanged, and the conductive disk 1 and the end of the composite rope are fixed on the turntable 6 and rotate synchronously with it. Under the condition of ensuring normal power supply, the end of the composite rope will not be twisted, which can reduce the damage of the composite rope.

[0031] In this embodiment, two turntables 6 are provided in the base station body 4, one of which is used for the retraction and extension of the composite rope, and the other turntable 6 is used for the retraction and extension of the power line. For the other turntable 6, two conductive disks 1 are installed on the turntable 6, and each conductive disk 1 is connected to the positive and negative conductive wires in the power line. For example, a terminal is provided on the conductive disk 1, and the conductive wire is connected to the terminal. The conductive contact 2 is fixed on the base station body 4. For example, a V-shaped spring sheet is provided on the base station body 4, and the conductive contact 2 is provided on the V-shaped spring sheet. The V-shaped spring sheet can be connected to the component to be energized (for example, another cable). Among them, the conductive contact 2 corresponding to the composite rope and the conductive contact 2 corresponding to the power line can be connected according to the electrical polarity (that is, the conductive contacts 2 corresponding to the two turntables 6 are connected one by one), and the power line is then connected to an external power source, so that the window cleaning robot can be powered through these conductive disks 1, conductive contacts 2 and conductive wires. When the turntable 6 retracts and releases the power cord, the conductive contact 2 remains in position, the conductive disk 1 and the end of the power cord are fixed on the turntable 6 and rotate synchronously therewith, and under the condition of ensuring normal power supply, the end of the power cord will not be twisted, which can reduce damage to the power cord.

[0032] In addition, a battery 8 may be built into the base station body 4 to power the device, eliminating the need for plugging in, thereby enhancing the mobility of the device.

[0033] Of course, the cable 5 that is retracted and released by the turntable 6 in the base station may include only a composite rope or a power cord, or may include both a composite rope and a power cord.

[0034] The above embodiments are preferred implementation schemes of the present utility model. Any obvious replacements without departing from the concept of the present technical solution are within the protection scope of the present utility model.
