Description

Technical Field

[0001] This utility model belongs to the field of cleaning, and in particular relates to a power receiving mechanism, a rear cover device, and a cleaning equipment. Background Technology

[0002] Current cleaning robots automatically return to their workstations to recharge when their battery is low. However, the charging current for cleaning robots is relatively high, reaching up to 15A. This requires the surface of the charging and receiving electrodes to be kept shiny and free of scratches. Scratches can cause poor contact during charging, leading to increased temperature of the receiving electrodes under high current conditions, and ultimately causing aging of the surface of the receiving electrodes. Summary of the Invention

[0003] In view of the above-mentioned deficiencies or defects in the prior art, the present invention provides a power receiving mechanism, a rear cover device, and a cleaning device with a long service life.

[0004] The power receiving mechanism provided by this utility model includes: a rear shell, on which a first receiving groove is provided that is recessed forward, and there are two first receiving grooves; and two receiving electrode plates, which are installed in the first receiving grooves, with a gap between the receiving electrode plates and the side wall of the first receiving groove, and the receiving electrode plates protruding from the rear wall of the rear shell.

[0005] The power receiving mechanism provided in this embodiment has a gap between the first receiving groove and the receiving electrode plate. This gap allows heat dissipation when the receiving electrode plate heats up, preventing it from burning out due to overheating and increasing the lifespan of the power receiving mechanism. The receiving electrode plate protruding from the rear wall of the rear housing prevents the charging electrode plate of the workstation from contacting the rear housing when the cleaning equipment and the workstation are misaligned.

[0006] Optionally, the bottom of the first receiving groove is provided with a through hole, and the receiving electrode plate is provided with a threaded hole. The receiving electrode plate is fixedly installed on the rear shell by screws that pass through the through hole and the threaded hole in sequence.

[0007] Optionally, the bottom of the first receiving groove is provided with a through hole, and the receiving electrode plate is provided with a wiring hole, through which the power line passes and connects to the wiring hole of the receiving electrode plate.

[0008] Optionally, the power receiving mechanism further includes a front shell that covers the front part of the rear shell, the first receiving groove is disposed on the surface of the rear shell away from the front shell, the front wall of the rear shell is provided with a third mounting post, the front shell is provided with a mounting hole, and the front shell is mounted on the rear shell by fasteners that pass through the mounting hole and the third mounting post in sequence.

[0009] Optionally, the rear cover is provided with a second receiving groove, which is located between the two first receiving grooves, and a charging connector is provided in the second receiving groove.

[0010] Optionally, the receiving electrode is elongated and extends along the vertical direction of the rear shell, and the two receiving electrodes are mounted side by side on the rear shell along the horizontal direction of the rear shell.

[0011] The rear cover device provided by this utility model includes a rear cover and the aforementioned power receiving mechanism. The rear cover has an opening, and the edge of the opening has a forward-extending flange. The rear shell abuts against the flange, and the power receiving electrode is exposed in the opening. The power receiving surface of the power receiving electrode is lower than the rear wall of the rear cover.

[0012] The rear cover device provided by this utility model has a forward-extending flange on the opening of the rear cover, so that the receiving surface of the receiving electrode is lower than the rear wall of the rear cover. In this way, when the cleaning equipment is flipped over, it is the rear cover, not the receiving electrode, that touches the ground, which is less likely to damage the receiving electrode. It can also prevent external objects from touching the two receiving electrodes at the same time, so as to prevent short circuit between the two receiving electrodes.

[0013] Optionally, the front wall of the rear cover is provided with a first mounting post, which is located on the outer periphery of the flange, and the rear cover is provided with a second mounting post. The front shell and the rear cover are fixedly installed together by fasteners passing through the first and second mounting posts.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] The power receiving mechanism provided in this embodiment includes a rear shell 1, on which a first receiving groove 11 is recessed forward; and a receiving electrode 2, which is installed in the first receiving groove 11. A gap is provided between the receiving electrode 11 and the side wall of the first receiving groove 11, and the receiving electrode 2 protrudes from the rear wall of the rear shell 1. The distance by which the receiving electrode 2 protrudes from the rear wall of the rear shell 1 is, for example, 0.5 mm or 1 mm.

[0027] The power receiving mechanism provided in this embodiment has a gap between the first receiving groove and the receiving electrode plate. This gap allows heat dissipation when the receiving electrode plate heats up, preventing it from burning out due to overheating. The receiving electrode plate protrudes from the rear wall of the rear housing, preventing the charging electrode plate of the workstation from contacting the rear housing when the cleaning equipment and the workstation are misaligned.

[0028] One of the two receiving electrodes is the positive electrode, and the other is the negative electrode. The receiving electrode consists of a copper substrate, a nickel plating layer covering the substrate, and a silver plating layer covering the nickel plating layer. The nickel plating layer prevents oxidation of the substrate, and the silver plating layer increases the conductivity of the receiving electrode.

[0029] The bottom of the first receiving groove 11 is provided with a through hole 111, and the receiving electrode plate 2 is provided with a threaded hole 21. The receiving electrode plate 2 is fixedly installed on the rear shell 1 by screws that pass through the through hole 111 and the threaded hole 21 in sequence.

[0030] The bottom of the first receiving tank 11 is provided with a through hole 112, and the receiving electrode plate 2 is provided with a wiring hole 22. The power cord passes through the through hole 112 and connects to the wiring hole 22 of the receiving electrode plate 2. One end of the power cord is connected to the receiving electrode plate, and the other end is connected to the battery of the cleaning device.

[0031] The power receiving mechanism also includes a front shell 3 that covers the front of the rear shell 1. A first receiving groove 11 is provided on the surface of the rear shell 1 away from the front shell 3, that is, the first receiving groove 11 is provided on the rear wall of the rear shell 1. The front shell 3 prevents components inside the cleaning device from passing through the through hole and contacting both receiving electrode plates 2 simultaneously, thus avoiding a short circuit between the two receiving electrode plates 2. A third mounting post 16 is provided on the front wall of the rear shell 1, and a mounting hole 31 is provided on the front shell 3. The front shell 3 is mounted on the rear shell 1 by fasteners that pass through the mounting hole 31 and the third mounting post 16 in sequence.

[0032] The rear cover 1 is provided with a second receiving groove 12, which is located between two first receiving grooves 11, and a charging connector 14 is provided in the second receiving groove 12.

[0033] Generally, when a cleaning device is low on power, it goes to a workstation to charge. When the charging contacts on the workstation and the receiving contacts on the cleaning device make contact, the cleaning device sends a successful docking signal to the workstation, which then charges the cleaning device. However, if the cleaning device is completely out of power, even if the charging contacts on the workstation and the receiving contacts on the cleaning device make contact, the cleaning device will not be able to send a successful docking signal because it has no power, preventing the workstation from charging it. In this case, the user connects a charging cable between the charging connector and an external socket to charge the cleaning device. Additionally, if the workstation or the receiving contacts malfunction, the user can manually charge the cleaning device by connecting a charging cable between the charging connector and the socket.

[0034] The receiving electrode 2 is long and strip-shaped, and extends along the vertical direction of the rear shell 1. Two receiving electrode 2 are installed side by side on the rear shell 1 along the horizontal direction of the rear shell 1.

[0035] The workstation has a docking cavity at its lower part, with guide wheels on both side walls and a ramp at the bottom. A power receiving mechanism is installed on the rear wall of the docking cavity, comprising a charging electrode and an elastic element. The elastic element drives the charging electrode to extend forward. After ascending the ramp, the receiving electrode of the cleaning equipment contacts the charging electrode of the workstation. Then, the drive wheel of the cleaning equipment stops moving, and the cleaning equipment moves forward slightly under the push of the elastic element. Because the cleaning equipment stops at different positions in the forward and backward directions on the ramp each time, it has a large floating space in the vertical direction. The floating space on the left and right sides of the cleaning equipment is usually small due to the limiting effect of the guide wheels. In this embodiment, by setting the receiving electrode to a long strip shape and arranging two receiving electrodes vertically side-by-side on the rear shell, the contact space between the receiving electrode and the charging electrode in the vertical direction is increased. This ensures stable contact between the receiving electrode and the charging electrode even with significant vertical floating during the pile alignment process.

[0036] The forward direction of the cleaning equipment is front-to-back, the vertical direction is up-down, and the left-to-right direction is perpendicular to both. The rear casing faces the same direction as the cleaning equipment.

[0037] The rear cover device provided in this embodiment includes a rear cover 4 and the aforementioned power receiving mechanism. The rear cover 4 has an opening, and the edge of the opening has a forward-extending flange 41. The rear shell 1 abuts against the flange 41, that is, the rear wall of the rear shell 1 abuts against the flange. The power receiving plate 2 is exposed in the opening, and the power receiving surface of the power receiving plate 2 is lower than the outer wall of the rear cover 4. The distance between the power receiving surface of the power receiving plate 2 and the outer wall of the rear cover 4 is 3mm to 7mm, for example, 3mm, 4mm, 5mm, 6mm and 7mm.

[0038] By providing an opening in the rear cover 4, most of the rear shell 1, the receiving electrode plate 2, and the charging connector 14 are exposed through the opening. The rear cover device provided in this embodiment has a forward-extending flange in the opening of the rear cover, and the charging surface of the receiving electrode plate 2 is lower than the rear wall of the rear cover 4. In this way, when the cleaning device is flipped back, it is the rear cover, not the receiving electrode plate, that touches the ground. The receiving electrode plate 2 is less likely to touch the ground, is less likely to be damaged, and can prevent external objects from touching both receiving electrode plates at the same time, thus preventing a short circuit between the two receiving electrode plates.

[0039] The inner wall of the rear cover 4 is provided with a first mounting post 42, which is located on the outer periphery of the flange. The rear shell is provided with a second mounting post 13. The rear cover 4 and the rear shell 1 are fixed together by fasteners passing through the first mounting post 42 and the second mounting post 13.

[0040] The rear cover 4 is also provided with two positioning holes 43, which are located on both sides of the power receiving mechanism, for the positioning pins of the workstation to be inserted. The workstation is equipped with positioning pins, and the positioning pins and positioning holes work together to achieve accurate alignment between the cleaning equipment and the workstation.

[0041] An infrared receiver 44 is also installed on the rear cover 4, and an infrared transmitter is provided on the workstation. Through the cooperation of the infrared transmitter and the infrared receiver, the alignment between the cleaning equipment and the workstation is achieved. A rear-view camera 47 is also provided on the rear cover 4 to collect images of the area around the cleaning equipment.

[0042] The rear cover 4 is also equipped with a dust exhaust port 46 and an air inlet 45. The dust exhaust port 46 is connected to the dust box inside the cleaning equipment through a dust exhaust pipe, and the air inlet 45 is connected to the dust box inside the cleaning equipment through an air inlet pipe. The garbage in the dust box is discharged through the dust exhaust port under the dual action of the suction force of the dust exhaust pipe and the blowing force of the air inlet pipe.

[0043] A water receiving mechanism is installed on the rear cover 4. The water receiving mechanism is located below the power receiving mechanism. The water receiving mechanism includes a connecting pipe 5 and a transfer pipe 6. The connecting pipe 5 is provided with a water injection hole for the water injection pipe of the workstation to extend into. The transfer pipe 6 includes a horizontal pipe 61 and a vertical pipe 62. The horizontal pipe 61 is connected to the connecting pipe 5, and the vertical pipe 62 is connected to the clean water tank through a hose.

[0044] The rear cover device provided in this embodiment places the water receiving mechanism below the power receiving mechanism. This prevents water from leaking onto the power receiving mechanism when the water receiving mechanism leaks, thus avoiding a short circuit in the power receiving mechanism. The clean water tank is installed on the middle frame of the cleaning equipment.

[0045] The cleaning equipment provided in this embodiment includes a chassis 7, a middle frame, and the aforementioned rear cover device. The middle frame is installed on top of the chassis, and the rear cover device is installed at the rear of the middle frame.

[0046] A side cover device is installed on the side of the mid-frame, comprising a side cover 81, an indicator light 83 and a speaker 82 mounted on the side cover 81. A front cover device is installed at the front of the mid-frame, on which a forward-looking camera, an ultrasonic sensor, and a line laser sensor are mounted. A roller towing device 9 is located at the rear of the chassis, comprising a support, a roller mounted below the support, a motor mounted above the support, and a gearbox mounted on the side of the support. The motor drives the roller to rotate through the gearbox.

[0047] The above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0049] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
