Description

Technical Field

[0001] The utility model belongs to the technical field of anti-ant of electrical equipment, and particularly relates to a charging station mainly used for outdoor robots. Background Art

[0002] There are many insects in the home garden environment, which usually live in the damp and dark underground, on the branches of plants or in the wood of doors and windows. Some outdoor electrical equipment is easy to attract insects, especially ants, especially equipment such as lawn mower robots that work outdoors all year round.

[0003] The charging stations of lawn mower robots all require an external power supply. Usually, one end of the power cord is connected to the control panel in the charging station, and the other end is connected to the municipal power grid. An adapter is generally included between the control panel and the municipal power grid. Therefore, at least one threading hole is provided on the charging station shell for the power cord to pass through the charging station shell. For lawn mower robots that need to lay wire boundaries, the threading hole is also used for the boundary wire to pass through the charging station shell.

[0004] In the prior art, there are holes or gaps for threading wires on the outer shell of the charging station. Since the charging station is placed outdoors (usually on the lawn) for a long time, and the internal control panel continues to work and generate heat, an environment is formed in the outer shell of the charging station that attracts insects (especially ants) to build nests. Ants building nests in the outer shell of the charging station will affect the heat dissipation of the control panel on the one hand, and on the other hand, the formic acid and other substances they secrete will corrode electronic devices, which can easily cause the entire lawn mowing robot system to malfunction.

[0005] Some publicly available patented technologies provide some solutions, such as the use of talcum powder or anti-ant agents, but improper handling of such substances will cause secondary pollution problems.

[0006] In some other solutions, the threading hole of the power cord is arranged at the upper part of the charging station shell. Although it can reduce the possibility of ants entering the shell to a certain extent, it still cannot eliminate the risk. Utility Model Content

[0046] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.

[0047] In the following description, certain specific details are set forth for the purpose of illustrating the various disclosed embodiments to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments may be practiced without one or more of these specific details. In other cases, well-known devices, structures, and techniques associated with the present application may not be shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0048] References throughout the specification to "one embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0049] In the following description, in order to clearly demonstrate the structure and working mode of the present invention, many directional words will be used for description, but the words "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", "down" and the like should be understood as convenient terms and should not be understood as restrictive terms; in the present application, when the robot is docked with the charging station, the side facing the robot is defined as "front" and the side facing away from the robot is defined as "back".

[0050] like Figure 1 The outdoor robot charging station shown includes a base 1 and a charging component 2.

[0051] The charging assembly 2 is fixedly connected to the base 1. In addition, the charging assembly 2 is provided with a charging interface 4 and a control panel assembly 6. When charging, the charging interface 4 on the lawn mower robot is docked with the charging interface 4 of the charging station, and the base 1 carries the lawn mower robot.

[0052] Combination Figure 2 It can be seen that the base 1 provides a platform suitable for the lawn mower robot to enter and exit, and is provided with anti-slip ribs. The charging interface 4 is installed on the charging station housing 3. Figure 5 The side profile of the overall device can be seen.

[0053] from Figure 3 and Figure 4 It can be seen that the charging assembly 2 includes a working space formed by a first shell 3a and a second shell 3b, and the charging interface 4 and the control panel assembly 6 are fixed on the second shell 3b.

[0054] A first foot portion 10 is provided on each of two sides of the bottom of the first housing 3 a , and a threading hole 7 is provided on the first foot portion 10 on the left side, and the threading hole 7 faces a direction away from the charging interface 4 .

[0055] Correspondingly, a second foot 11 is provided on each side of the bottom of the second shell 3b, and a wire passage 8 is provided in the internal space formed by the second foot 11, and a seal 5 is installed in the wire passage 8. At the same time, three second limiting grooves 15 are provided on the horizontal plate between the two second feet 11 on the second shell 3a.

[0056] On the other hand, two mounting grooves 9 are provided on the base 1, and a drainage hole 16 is provided in the two mounting grooves 9. Of course, there is no restriction on the shape or number of the drainage hole 16, so long as it is convenient to drain the accumulated water in the mounting groove 9 downward. Figure 6 It can be seen that the drainage hole 16 runs through the base 1, so that the accumulated water is directly drained to the ground.

[0057] In the above design, the charging interface 4 and the control board assembly 6 are installed on the inner and outer sides of the second housing 3b, respectively, wherein the charging interface 4 is located on the outer side of the second housing 3b, and the control board assembly 6 is located on the inner side of the second housing 3b. After installation, the first housing 3a is buckled onto the second housing 3b, so that the first leg 10 of the first housing 3a and the second leg 11 of the second housing 3b are buckled with each other, and at this time, the threading hole 7 on the first leg 10 is exactly located at the exit of the wire passage 8 in the second leg 11.

[0058] Combination Figure 3 The structure shown, when the first foot 10 and the second foot 11 are combined and installed in the two mounting grooves 9 on the base 1, is fastened in the screw holes inside the two mounting grooves 9 by screws passing through the first foot 10 and the second foot 11 in sequence, and the screw holes adopt a cylindrical structure with a hollow thread.

[0059] like Figure 7 As shown, from a top view, when the charging assembly 2 is installed on the base 1, the charging interface 4 is exposed on the charging station housing 3 and faces the upper space of the base 1, so that the lawn mowing robot on the base 1 can be connected and charged.

[0060] like Figure 8 As shown, Figure 8 The relative position relationship between the first space 17 and the third space 19 is shown. Fig.16 See the position of the second limiter 13, and Fig.18 The position of the second limiting groove 15 is shown. When the first housing 3a and the second housing 3b are buckled, the three second limiting portions 13 on the first housing 3a are inserted into the three second limiting grooves 15 of the second housing 3b to complete the assembly. The cooperation between the second limiting portion 13 and the second limiting groove 15 prevents the first housing 3a from warping. There is no hook at the free end of the second limiting portion 13, which is convenient for maintenance.

[0061] However, in order to facilitate the water entering the first space 17 through the charging interface 4 or other gaps, the second limiting portion 13 and the second limiting groove 15 are not tightly connected, but have a fitting gap. The fitting gap becomes a connecting channel between the first space 17 and the third space 19. In order to ensure that ants cannot enter the first space 17 upward through the connecting channel, it is necessary to ensure that there is a certain height between the base 1 and the fitting gap, that is, the height of the third space 19, which is taken as D.

[0062] like Figure 8 As shown, the vertical distance between the base 1 and the fitting gap is D, and the value of D is preferably greater than 10 mm, but not too large, otherwise the third space 19 will occupy a large equipment space, increasing packaging and transportation costs. Therefore, the value of D is preferably 16 to 20 mm.

[0063] like Fig. 9 and Fig.10 As shown, the relative positions of the first space 17, the second space 18 and the third space 19 are mainly shown. When the first shell 3a is combined and docked with the second shell 3b, the main body of the first shell 3a and the main body of the second shell 3b are buckled to form a relatively independent first space 17. When the second shell 3b is combined and docked with the base 1, the second foot 11 is buckled with the base 1 to form a relatively independent second space 18. When the charging component 4 is combined and docked with the base 1, a third space 19 that is connected from front to back is formed between the two second feet 11 and under the bottom surface of the main body of the second shell 3b.

[0064] from Fig.10 As can be seen in the figure, the wire passage 8 is arranged in the second space 18. The cable enters the wire passage 8 from the wire threading hole 7 and then passes upward through the wire threading hole 25 in the seal 5 and then enters the first space. The structure of the seal 5 is as shown in FIG. Fig. 20 The sealing member is arranged in the second space 18 to reduce direct contact with the external environment, especially to avoid sunlight and rain, which is conducive to prolonging the service life.

[0065] According to a preferred embodiment disclosed in the present utility model, the seal 5 is preferably a rubber seal 5, which is filled in the wire passage 8 and squeezed by the inner wall of the wire passage 8, so that the wire passage 8 is completely sealed and there is no gap for ants to enter; those skilled in the art, inspired by the technical solution of the present disclosure, adjust the shape, structure or material of the seal 5, all of which fall within the protection scope disclosed in the present utility model; it can be understood that since the seal 5 is made of rubber material in one embodiment, the diameter of the threading hole 25 on the seal 5 can be slightly smaller than the diameter of the cable to provide a pre-tightening force so that the seal 5 fits tightly to the cable; it should be understood that the diameter of the threading hole 25 should be sufficient to allow the cable to pass through, and preferably, the diameter of the threading hole 25 shall not be less than half of the diameter of the cable; it should be understood that the relationship between the threading hole 25 and the diameter of the cable is only a preferred embodiment and should not be understood as a limitation on the protection scope of the present utility model; in different embodiments, the thickness of the cable may be different, but the diameter of the threading hole 25 on the seal 5 always matches the diameter of the cable to effectively prevent ants from entering the interior of the charging station.

[0066] In one embodiment, in order to prevent the seal 5 from slipping after filling the wire-passing channel 8, a card plate 24 may be provided on the inner wall of the wire-passing channel 8, and correspondingly, a card slot 23 matching the card plate 24 is provided on the outer side of the seal 5; the card plate 24 and the card slot 23 not only make the seal 5 more isolating, but also prevent it from falling off from the wire-passing channel 8; obviously, due to the friction between the card slot 23 of the seal 5 and the card plate 24, it is not easy to be pulled out by insects or fall off due to the impact of rainwater; usually, the seal 5 is first sleeved on the cable, and the seal 5 is inserted into the card plate 24 when the cable is installed. The design of the card slot 23 and the card plate 24 facilitates installation.

[0067] like Fig.11 As shown, after the first shell 3a and the second shell 3b are buckled together, it can be seen from the cross-sectional view that the second space 18 is formed by the buckling of the second leg 11 and the base 1, and is located inside the second leg 11, and combined with Fig.21 As can be seen from the large-scale drawing, the junction of the first limiting portion 12 and the first limiting groove 14 is located in the second space 18. As can be seen from the drawing, the first limiting portion 12 is specifically constructed in a U shape.

[0068] And from Fig.16 It can be seen that the first limiting portion 12 is located on both side walls of the first housing 3a, and when the first limiting portion 12 is inserted into the first limiting groove 14, it is located above the second space 18. The first limiting groove 14 is provided at corresponding positions on both side walls of the second housing 3b.

[0069] like Fig.12As shown, the charging station housing 3 is also provided with a vibration damping block 20, which is mounted on the second housing 3b and is located below the charging interface 4. As can be seen from the figure, the vibration damping blocks 20 are a pair, symmetrically arranged on the second housing 3b, and each block corresponds to a position below a charging interface 4.

[0070] from Fig.13 The relative positions of the vibration damping block 20 and the charging interface 4 can be seen.

[0071] from Fig.14 and Fig.15 It can be seen that the installation of the vibration-damping block 20 is achieved by snapping the snap-fitting portion 22 on the vibration-damping block 20 into the snap-fitting hole 21 on the second housing 3b. As an optional embodiment, the vibration-damping block 20 acts as a counterweight to increase the overall stability of the device.

[0072] like Fig.17 As shown, Fig.17 The second housing 3b is shown to be installed in the installation groove 9 of the base 1, and a wire passage 8 is formed between the second foot 11 and the base 1, and a sealing member 5 is arranged in the wire passage 8 (see the detailed figure). Fig. 20 ).

[0073] Combined with Fig.18 It can be seen that the three second limiting grooves 15 on the second housing 3b are arranged at positions where the three second limiting portions 13 on the first housing 3a are inserted into the three second limiting grooves 15 during installation.

[0074] In addition, Fig.18 The state where the seal 5 is taken out can be seen in FIG.

[0075] Fig.19 The structure of the charging interface 4 is shown, which is a prior art and can be installed on the second housing 3b when in use.

[0076] When assembling the present invention, firstly, the second housing 3b is connected to the base 1, then the first housing 3a is connected to the second housing 3b, and finally, screws are passed through the first housing 3a, the second housing 3b and the base 1 in sequence to fix the three together. Alternatively, the first housing 3b is first buckled with the second housing 3a, and then connected to the base 1.

[0077] During assembly, after aligning the lower end of the first limiting portion 12 with the upper end of the first limiting groove 13, the first shell 3a is pressed downward, and the first shell 3a and the second shell 3b can be assembled together in a preset relative position by guiding the first limiting portion 12 and the first limiting groove 14.

[0078] When the first housing 3a and the second housing 3b are assembled together, the second limiting portion 13 is vertically inserted into the second limiting groove 15 to limit the relative position of the first housing 3a and the second housing 3b in the front-to-back direction. The second limiting portion 13 and the second limiting groove 15 have a matching gap for draining water entering the first space 17. Due to the existence of the third space 19, there is a gap between the matching gap and the base 1, which can effectively prevent ants from entering.

[0079] The first space 17 is connected to the outside of the charging assembly 2 through a wire passage 8, and the wire passage 8 is used to accommodate the power cord. A wire outlet hole 7 is provided at the bottom of a first foot portion 10 of the first housing 3a, and the wire outlet hole 7 is connected to the wire passage 8. Overall, the wire outlet hole 7 is arranged at the bottom of the charging assembly 2, which shortens the length of the power cord.

[0080] After the assembly is completed, the base 1 is fixed at a suitable position. When in use, the lawn mowing robot is driven onto the base 1 and can be charged using the charging interface 4 .

[0081] Of course, this design can also be applied to other small and medium-sized outdoor electrical equipment for ant prevention, such as machinery and equipment used in courtyards and gardens.

[0082] It is not difficult to find from the above content that, due to the provision of the seal 5, even if a cable extends out of the cable passage 8, the interior of the shell can still be isolated from the external environment; thus, the charging station can be placed on the lawn and has a wider range of use; and the blocking effect on insects such as ants can be achieved in different user usage scenarios.

[0083] The specific embodiments described in this article are merely examples of the spirit of the utility model; technicians in the technical field of the utility model can make various modifications or additions to the described specific embodiments or replace them in a similar manner, but they will not deviate from the spirit of the utility model or exceed the scope defined by the attached claims.
