Description

Technical Field

[0001] This invention relates to the field of robot charging device technology, and in particular to a dustproof charging device for use in inspection robots. Background Technology

[0002] There are currently two methods for charging robots: one is direct charging after recall, and the other is autonomous charging at a charging station. The first method, direct charging, cannot be used for online charging, especially for inspection robots, which cannot charge while performing tasks. The second method represents the current development direction for robot energy replenishment. The main problem that remote autonomous charging technology needs to solve is enabling the robot to automatically dock with the charging dock through an automated control program. Existing charging docking devices are generally fixed, requiring high docking precision. If the socket position changes, docking is difficult for the robot to complete automatically and requires human intervention. Some remote autonomous charging systems use wireless charging technology, but because wireless charging has a lower maximum charging current, it cannot meet the robot's need for rapid charging.

[0003] Because there is a lot of dust in the environment above overhead power lines, charging devices need to take into full consideration the dust prevention problem for long-term use. However, some improved remote autonomous charging devices do not take the dust prevention problem into account, and are prone to dust accumulation and poor dust prevention effect. When the dust accumulation is serious, it directly affects the charging connection. Summary of the Invention

[0004] In response to the problems raised in the background technology, the purpose of this invention is to provide a dustproof charging device for inspection robots. It has good dustproof effect, can be used outdoors for a long time, and effectively reduces the accuracy requirements for docking, making it convenient to achieve automatic docking. It solves the problem that existing charging devices are prone to dust accumulation and have poor dustproof effect, which affects charging docking.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A dustproof charging device for an inspection robot includes a charging base assembly and a charging head assembly;

[0007] The charging base assembly includes a charging base body, an adjustment structure, and a first electrode. The charging base body includes a connecting part and an electrode mounting part. The top of the connecting part is fixedly installed on the adjustment structure, and the bottom end face of the connecting part is connected to the electrode mounting part. The adjustment structure is rotatably installed on the bearing seat of the charging pile mounting plate.

[0008] The electrode mounting part is provided with a first cavity, the first cavity is open downwards, the first electrode is mounted on the inner side wall of the electrode mounting part, and the first electrode is located in the first cavity.

[0009] The charging head assembly includes a charging head body and a second electrode. The second electrode is installed on the outer side wall of the top of the charging head body. When the charging head body is inserted into the first cavity, the first electrode and the second electrode are electrically connected.

[0010] Furthermore, the charging dock assembly also includes a waterproof baffle;

[0011] The connecting part is provided with a second cavity, which is disposed through the side wall of the connecting part. The charging base body is provided with a wire hole for wiring the first electrode. The wire hole is disposed through the bottom wall of the connecting part and the top wall of the electrode mounting part. One end of the wire hole is connected to the first cavity, and the other end of the wire hole is connected to the second cavity.

[0012] The waterproof baffle is installed on the connecting part and is located on the outside of the second cavity. The waterproof baffle is used to seal the second cavity.

[0013] To further explain, the connecting part is provided with a waterproof step, the waterproof step protruding upward from the connecting part, and the wire hole is provided at the waterproof step.

[0014] Furthermore, the charging dock assembly also includes a protective cover, which is disposed on the outside of the connecting portion;

[0015] The protective cover is provided with a clearance opening for avoiding the waterproof baffle, and the waterproof baffle is embedded in the clearance opening.

[0016] Furthermore, the charging dock assembly also includes a bottom sealing plate, which is installed at the bottom of the electrode mounting portion. The bottom sealing plate has a connection interface in the middle for the charging head body to be inserted. The outer periphery of the connection interface has a first arc surface, and the bottom of the first electrode has a second arc surface, which is located above the first arc surface.

[0017] The top of the charging head body is provided with a docking part, which cooperates with the first arc surface and the second arc surface.

[0018] To further explain, there are two first electrodes, which are mounted opposite each other on the inner sidewall of the electrode mounting portion;

[0019] There are two second electrodes, which are symmetrically installed on the charging head body. When the charging head body is inserted into the first cavity, the first electrode and the second electrode are electrically connected in a one-to-one correspondence.

[0020] Furthermore, the charging dock assembly also includes a first spring, one end of which is connected to the inner sidewall of the electrode mounting portion, and the other end of which is connected to the first electrode.

[0021] Furthermore, the charging dock assembly also includes a second spring, one end of which is connected to the bearing seat of the charging pile mounting plate, and the other end of which is connected to the top of the connecting portion.

[0022] To further clarify, the first electrode, the first spring, and the second spring are located on the same horizontal plane;

[0023] Two first springs are provided, symmetrically arranged on the inner sidewall of the electrode mounting part. Two second springs are provided, symmetrically arranged on both sides of the adjustment structure.

[0024] To further explain, the adjustment structure includes a mounting shaft and a spherical adjustment component. The spherical adjustment component is fitted onto the upper part of the mounting shaft, and the outer ring of the spherical adjustment component is mounted on the bearing seat of the charging pile mounting plate. The top of the connecting part is fixedly mounted on the lower part of the mounting shaft.

[0025] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0026] 1. By setting an adjustment structure, since the adjustment structure is rotatably installed on the bearing seat of the charging pile mounting plate, the main body of the charging base also swings relative to the charging pile mounting plate. That is, the main body of the charging base can rotate within a certain range. When the charging head body and the charging base body are docked, docking can be achieved within a certain range. Even if there is a certain positional deviation between the main body of the charging base and the charging head body, the main body of the charging base can adapt to the change in position. It does not require a particularly high-precision positioning relationship to achieve docking, which reduces the accuracy requirements of docking and enables automatic docking.

[0027] 2. By installing the first electrode on the inner wall of the electrode mounting part and the second electrode on the outer wall of the top of the charging head body, compared with the existing charging device that sets the electrodes on the upper surface of the charging head, since the electrode setting direction is in the side direction, even if dust or other debris sticks to the first or second electrode during use, the dust or other debris will fall off naturally under the action of gravity and will not accumulate on the surface of the electrode. Moreover, since the charging base body and the charging head body will move during charging docking, dust and other debris will easily fall off during the movement of the charging base body and the charging head body. It can effectively remove dust and other debris during charging docking, achieve a self-cleaning effect, has good dustproof effect, and can be used outdoors for a long time.

[0028] 3. By setting up a second cavity and a wire passage hole, wiring operations can be facilitated. The wire passage hole is used for wiring and wire passage of the first electrode during use, while the waterproof baffle can seal the second cavity to prevent water from entering the second cavity. This prevents water from entering the first cavity through the wire passage hole and affecting docking and charging. The waterproof effect is good, ensuring the stability of the docking and charging process. Attached Figure Description

[0041] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0042] In the description of this invention, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, features defined with "first" and "second" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0043] like Figures 1 to 10 As shown, a dustproof charging device for an inspection robot includes a charging base assembly 1 and a charging head assembly 2.

[0044] The charging base assembly 1 includes a charging base body 11, an adjustment structure 12, and a first electrode 13. The charging base body 11 includes a connecting part 111 and an electrode mounting part 112. The top of the connecting part 111 is fixedly mounted to the adjustment structure 12, and the bottom end face of the connecting part 111 is connected to the electrode mounting part 112. The adjustment structure 12 is rotatably mounted on the bearing seat 31 of the charging pile mounting plate 3.

[0045] The electrode mounting part 112 is provided with a first cavity 1121, which is open downwards. The first electrode 13 is mounted on the inner side wall of the electrode mounting part 112 and is located inside the first cavity 1121.

[0046] The charging head assembly 2 includes a charging head body 21 and a second electrode 22. The second electrode 22 is installed on the outer side wall of the top of the charging head body 21. When the charging head body 21 is inserted into the first cavity 1121, the first electrode 13 is electrically connected to the second electrode 22.

[0047] By setting the adjustment structure 12, since the adjustment structure 12 is rotatably mounted on the bearing seat 31 of the charging pile mounting plate 3, the charging base body 11 also swings relative to the charging pile mounting plate 3. That is, the charging base body 11 can rotate within a certain range. When the charging head body 21 docks with the charging base body 11, docking can be achieved within a certain range. Even if there is a certain positional deviation between the charging base body 11 and the charging head body 21, the charging base body 11 can adapt to the change in position. It does not require a particularly high-precision positioning relationship to achieve docking, which reduces the accuracy requirements of docking and enables automatic docking.

[0048] Furthermore, by installing the first electrode 13 on the inner side wall of the electrode mounting part 112 and the second electrode 22 on the outer side wall of the top of the charging head body 21, compared with the existing charging devices that set the electrodes on the upper surface of the charging head, since the electrode setting direction is in the lateral direction, even if the first electrode 13 or the second electrode 22 is covered with dust or other debris during use, the dust and other debris will fall off naturally under the action of gravity and will not accumulate on the surface of the electrodes. Moreover, during charging docking, since the charging base body 11 and the charging head body 21 will move, the dust and other debris will easily fall off during the movement of the charging base body 11 and the charging head body 21. During charging docking, dust and other debris can be effectively removed, achieving a self-cleaning effect. The dustproof charging device used by the inspection robot has a good dustproof effect, can be used outdoors for a long time, and effectively reduces the accuracy requirements of docking, making it convenient to achieve automatic docking. It solves the problem that existing charging devices are prone to dust accumulation and have poor dustproof effect, which affects charging docking.

[0049] Furthermore, the charging dock assembly 1 also includes a waterproof baffle 14;

[0050] The connecting part 111 is provided with a second cavity 1111, which is disposed through the side wall of the connecting part 111. The charging base body 11 is provided with a wire hole 113 for wiring the first electrode 13. The wire hole 113 is disposed through the bottom wall of the connecting part 111 and the top wall of the electrode mounting part 112. One end of the wire hole 113 is connected to the first cavity 1121, and the other end of the wire hole 113 is connected to the second cavity 1111.

[0051] The waterproof baffle 14 is installed on the connecting part 111 and is located on the outside of the second cavity 1111. The waterproof baffle 14 is used to seal the second cavity 1111.

[0052] By setting the second cavity 1111 and the wire passage hole 113, wiring operations can be facilitated. The wire passage hole 113 is used for wiring and wire passage of the first electrode 13 during use. The waterproof baffle 14 can seal the second cavity 1111 to prevent water from entering the second cavity 1111, thereby preventing water from entering the first cavity 1121 through the wire passage hole 113 and affecting docking charging. The waterproof effect is good, ensuring the stability of the docking charging process.

[0053] To further explain, two waterproof baffles 14 are provided, and the two waterproof baffles 14 are symmetrically installed on the connecting part 111. The two waterproof baffles 14 are respectively installed at the corresponding second cavity 1111 of the connecting part 111. A wire outlet hole can be provided on one of the waterproof baffles 14, so that the wire connecting the first electrode 13 passes through the wire hole 113 from the first cavity 1121, passes through the second cavity 1111, and finally exits from the wire outlet hole on the waterproof baffle 14 to connect with external equipment.

[0054] To further explain, the connecting part 111 is provided with a waterproof step 1112, the waterproof step 1112 protrudes upward from the connecting part 111, and the wire hole 113 is provided at the waterproof step 1112.

[0055] By setting the waterproof step 1112, which protrudes upward from the connecting part 111, the top surface of the waterproof step 1112 is at a higher level than the inner wall of the bottom of the connecting part 111. With the wire hole 113 positioned at the waterproof step 1112, even if a small amount of rainwater enters the second mounting cavity, it will be below the top surface of the waterproof step 1112, effectively preventing rainwater from entering the wire hole 113.

[0056] Specifically, there are two wire-passing holes 113 and two waterproof steps 1112, with one wire-passing hole 113 corresponding to one waterproof step 1112, to facilitate wiring.

[0057] Furthermore, the charging dock assembly 1 also includes a protective cover 15, which covers the outside of the connecting portion 111;

[0058] The protective cover 15 is provided with a clearance opening 151 for avoiding the waterproof baffle 14, and the waterproof baffle 14 is embedded in the clearance opening 151.

[0059] By setting the protective cover 15, the protective cover 15 can protect the charging base body 11, effectively prevent the charging base body 11 from aging due to sun exposure during long-term use, and also play a role in waterproofing and dustproofing, ensuring the stability of docking and charging, and effectively extending the service life of the charging device.

[0060] Furthermore, by providing the clearance opening 151 on the protective cover 15 to avoid the waterproof baffle 14, the waterproof baffle 14 is installed on the connecting part 111 and embedded in the clearance opening 151. This allows the protective cover 15 and the waterproof baffle 14 to cooperate to form a dustproof and waterproof structure covering the outside of the connecting part 111, ensuring dustproof and waterproof performance. Specifically, the waterproof baffle 14 can be detachably installed on the connecting part 111 using fasteners 123 such as screws. After the protective cover 15 is placed over the connecting part 111, the waterproof baffle 14 is installed. At this time, the waterproof baffle 14 can also limit the movement of the protective cover 15, preventing it from moving and ensuring the structural stability of the charging base.

[0061] Furthermore, the charging dock assembly 1 also includes a bottom sealing plate 16, which is installed at the bottom of the electrode mounting part 112. The bottom sealing plate 16 has a connection interface 161 in the middle for the charging head body 21 to be inserted. The outer periphery of the connection interface 161 is provided with a first arc surface 162, and the bottom of the first electrode 13 is provided with a second arc surface 131, which is located above the first arc surface 162.

[0062] The top of the charging head body 21 is provided with a docking part 211, which cooperates with the first arc surface 162 and the second arc surface 131.

[0063] Specifically, the arc of the docking part 211 is set to be wider at the bottom and narrower at the top. By providing the first arc surface 162 along the outer periphery of the docking interface 161 and the second arc surface 131 at the bottom of the first electrode 13, the first arc surface 162 and the second arc surface 131 can play a guiding role, so that the docking part 211 and the docking interface 161 can be connected. This can ensure that even if there is a certain positional deviation between the charging base body 11 and the charging head body 21, the connection can be completed without requiring a particularly high-precision positioning relationship, making the connection convenient.

[0064] To further explain, there are two first electrodes 13, which are mounted opposite each other on the inner sidewall of the electrode mounting portion 112.

[0065] There are two second electrodes 22, which are symmetrically installed on the charging head body 21. When the charging head body 21 is inserted into the first cavity 1121, the first electrode 13 and the second electrode 22 are electrically connected in a one-to-one correspondence.

[0066] By setting two first electrodes 13 and two second electrodes 22, the first electrodes 13 and the second electrodes 22 are electrically connected in a one-to-one correspondence to achieve charging docking. Specifically, both the first electrodes 13 and the second electrodes 22 adopt an arc-shaped block structure, which makes it easier to insert and facilitate docking.

[0067] Furthermore, the charging dock assembly 1 also includes a first spring 17, one end of which is connected to the inner sidewall of the electrode mounting portion 112, and the other end of which is connected to the first electrode 13.

[0068] By setting the first spring 17 between the first electrode 13 and the electrode mounting part 112, the first electrode 13 is mounted on the electrode mounting part 112. When the charging head body 21 is inserted into the first cavity 1121, the inner wall of the first electrode 13 abuts against the outer wall of the second electrode 22. At this time, the first spring 17 is compressed, and the first spring 17 has a counter-pushing elastic force on the first electrode 13. This force makes the inner wall of the first electrode 13 press against the outer wall of the second electrode 22, thereby ensuring reliable contact of the electrodes after the charging base body 11 and the charging head body 21 are connected, and ensuring the stability of the charging connection.

[0069] To further explain, the second electrode 22 can be detachably mounted to the charging head body 21 by fasteners such as screws.

[0070] Furthermore, the charging dock assembly 1 also includes a second spring 18, one end of which is connected to the bearing seat 31 of the charging pile mounting plate 3, and the other end of which is connected to the top of the connecting part 111.

[0071] By setting the second spring 18, which functions as a reset spring, it is ensured that the charging base body 11 remains perpendicular to the charging pile mounting plate 3 when not charging, thus facilitating the smooth docking of the charging head body 21 on the inspection robot 5 side with the charging base body 11.

[0072] To further clarify, the first electrode 13, the first spring 17, and the second spring 18 are located on the same horizontal plane;

[0073] Two first springs 17 are provided, and the two first springs 17 are symmetrically arranged on the inner side wall of the electrode mounting part 112. Two second springs 18 are provided, and the two second springs 18 are symmetrically arranged on both sides of the adjustment structure 12.

[0074] To further explain, the adjustment structure 12 includes a mounting shaft 121 and a spherical adjustment component 122. The spherical adjustment component 122 is fitted onto the upper part of the mounting shaft 121, and the outer ring of the spherical adjustment component 122 is mounted on the bearing seat 31 of the charging pile mounting plate 3. The top of the connecting part 111 is fixedly mounted on the lower part of the mounting shaft 121.

[0075] By setting the adjustment structure 12, since the top of the connecting part 111 is fixedly installed on the mounting shaft 121, and the sliding surface of the spherical adjustment component 122 is spherical, the mounting shaft 121 can rotate and swing relative to the charging pile mounting plate 3 through the spherical adjustment component 122, so that the charging base body 11 also rotates and swings relative to the charging pile mounting plate 3. That is, the charging base body 11 can rotate within a certain range (rotation range such as...). Figure 1 As shown by angle α in the figure, when the charging head assembly 2 needs to dock with the charging base assembly 1, docking can be achieved within a certain range without requiring a particularly high-precision positioning relationship.

[0076] To further explain, the spherical adjustment component 122 specifically adopts a spherical connection mechanism such as a spherical bearing or a ball bearing, but is not limited to the above-mentioned types of spherical connection mechanisms.

[0077] Preferably, the adjustment structure 12 further includes a fastener 123. The top of the connecting part 111 is provided with a through hole. The mounting shaft 121 passes through the through hole and is inserted into the connecting part 111. The connecting part 111 is fixedly installed on the lower part of the mounting shaft 121 by the fastener 123, so that the stability of the connecting part 111 installed on the mounting shaft 121 is high, thereby improving the rotational stability of the charging base body 11 and ensuring the docking stability of the charging head assembly 2 and the charging base assembly 1.

[0078] Specifically, the fastener 123 adopts a combination of a retaining washer and a nut, which has a simple fixing structure and strong fastening stability.

[0079] It should be noted that in the existing adjustment structure 12, the connection between the charging base body 11 and the bearing seat 31 of the charging pile mounting plate 3 is a ball bearing connection, which can rotate 360 ​​degrees. Therefore, the connection between the charging base body 11 and the charging head body 21 is relatively complicated. Since the inspection robot 5 moves in a straight line, the positional deviation of the charging base body 11 will generally occur in the walking direction of the inspection robot 5. In this structure, the first electrode 13, the first spring 17 and the second spring 18 are located on the same horizontal plane, and the second spring 18 is symmetrically installed on both sides of the adjustment structure 12. Two first springs 17 are symmetrically arranged on the inner side wall of the electrode mounting part 112. When installing the charging base assembly 1, the first spring 17 and the second spring 18 are symmetrically arranged. The direction is the straight-line walking direction of the inspection robot 5. At this time, the second spring 18 can prevent the charging base body 11 from rotating, ensuring that the two first electrodes 13 are positioned on both sides of the straight-line walking direction of the inspection robot 5, and can restrict the charging base body 11 to swing only in the walking direction of the inspection robot 5. In this way, the adaptive rotation of the first electrodes 13 is achieved, ensuring that the first electrodes 13 are docked with the corresponding second electrodes 22, preventing electrode misalignment during docking, improving docking accuracy, and enabling the charging base body 11 to have a reset function. During charging docking, the docking method is simpler, and there is no need to adjust the deflection position of the charging base body 11. The charging base body 11 can perform self-correction and reset through the second spring 18.

[0080] Furthermore, the charging head body 21 or the charging base body 11 is also provided with a travel limit switch 23. The travel limit switch 23 is provided with a rocker plate 231 and a contact 2311. The travel limit switch 23 is used to determine whether the charging head body 21 and the charging base body 11 have completed docking.

[0081] Preferably, the travel limit switch 23 is fixedly installed on the charging head body 21 below the docking part 211. By setting the travel limit switch 23 on the charging head body 21, when the charging head body 21 and the charging base body 11 are docked (i.e., when the docking part 211 of the charging head body 21 is fully inserted into the docking interface 161 of the bottom sealing plate 16), the contact 2311 contacts the charging base body 11, and the rocker plate 231 of the travel limit switch 23 is pressed. At this time, the travel limit switch 23 is triggered and a signal is connected, so that after successful docking, the travel limit switch 23 sends a signal to the inspection robot 5 to execute the charging command. The inspection robot 5 will only connect the charging circuit to charge when it receives the charging command. If the charging head body 21 and the charging base body 11 are not docked, the inspection robot 5 cannot execute the charging command. The travel limit switch 23 can play a mechanical protection role to ensure the safety of the inspection robot 5 charging docking device during use.

[0082] like Figure 10 As shown, specifically, the charging pile mounting plate 3 is provided with a walking track 4 for the inspection robot 5 to walk on, and the bearing seat 31 is provided with collision inspection baffles 32 on both sides along the walking direction of the inspection robot 5.

[0083] The inspection robot 5 includes an arm 51, a walking component 52, and a lifting component 53. The walking component 52 is disposed on the top of the arm 51. The lifting component 53 is slidably mounted on the arm 51. The lifting component 53 includes a mounting base 531, a collision detection main board 532, and a pressure roller 533. The collision detection main board 532 is provided on both sides of the mounting base 531 along the walking direction of the inspection robot 5. The pressure roller 533 is mounted on the top surface of the mounting base 531. The charging head assembly 2 is installed between the two pressure rollers 533.

[0084] The walking assembly 52 includes a walking wheel 521 and a walking drive device 522. The output shaft of the walking drive device 522 is connected to the walking wheel 521. The walking wheel 521 is rolled on the walking track 4. The walking drive device 522 drives the walking wheel 521 to roll along the walking track 4, thereby causing the arm 51 to extend towards the charging base body 11 or retract away from the charging base body 11. Figure 11 As shown, the charging docking process is as follows:

[0085] When the collision detection mainboard 532 of the lifting assembly 53 collides with the collision detection baffle 32 of the charging pile mounting plate 3, the inspection robot 5 begins charging docking. The lifting assembly 53 slides downward along the arm 51, the pressure wheel 533 is released, and the arm 51 extends closer to the charging base body 11. A counting method is used to determine whether the arm 51 has extended to the preset charging base coordinate point by calculating the motor revolutions of the walking drive device 522. After the count is complete, when the arm 51 extends... When the charging head body 21 is extended to the preset coordinate point of the charging base body 11, it reaches directly below the charging base body 11. The lifting component 53 moves upward along the arm 51 to perform the pressing action of the pressing wheel 533. At this time, the charging head body presses against the charging base body 11. The travel limit switch 23 determines whether the charging head body 21 and the charging base body 11 have completed docking. If the charging head body 21 and the charging base body 11 can complete docking, charging will start; otherwise, an error will be reported.

These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
