The charging mechanism includes a charging module, one end of which has a first charging plug, and the other end of which is elastically connected to a slider module via a plurality of third elastic bodies. The third elastic bodies are perpendicular to a second transition surface of the slider module, thereby allowing the relative angle between the first charging plug and the second transition surface of the slider module to be elastically adjustable. Furthermore, for the second transition surface of the slider module, this embodiment also provides a base module on the side of the slider module facing away from the charging module, and the slider module and the base module are elastically connected via the first elastic bodies, thereby allowing the relative position of the second transition surface of the slider module relative to the first transition surface of the base module in a projection plane perpendicular to a first direction to be elastically adjustable.

Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a charging mechanism and cleaning system for charging cleaning equipment. Background Technology

[0002] Cleaning equipment such as floor scrubbers and cleaning robots usually need to be used with a cleaning base station, which is equipped with a charging mechanism to charge the cleaning equipment.

[0003] The cleaning equipment is usually equipped with a female charging plug, while the charging mechanism of the cleaning base station is usually equipped with a male charging plug. After the cleaning equipment returns to the cleaning base station, it can be charged by plugging and unplugging the male and female charging plugs. In addition, in order to ensure the accuracy of the plugging and unplugging, the male charging plug is often equipped with a centering function.

[0004] However, the alignment effect of the male charging plug in the relevant solutions is limited and cannot cope with the complex working conditions of positioning deviation of cleaning equipment when it is recharging. Utility Model Content

The charging mechanism includes a charging module. First, one end of the charging module in this embodiment is provided with a first charging plug, and the other end of the charging module is elastically connected to a slider module through a plurality of third elastic bodies. The third elastic bodies are perpendicular to the second transition surface of the slider module (i.e., the surface of the slider module facing the charging module), thereby the relative angle between the first charging plug and the second transition surface of the slider module is elastically adjustable.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: This application provides a charging mechanism and a cleaning system for charging cleaning equipment. The charging mechanism of this embodiment includes a base module, a slider module, and a charging module.

[0019] In this embodiment, the slider module is located between the base module and the charging module. The base module is used for fixed installation. The end of the charging module facing away from the slider module is provided with a first charging plug, such as a male charging tail plug.

[0020] In one aspect, the end of the charging module facing the slider module is elastically connected to the slider module through several third elastic bodies.

Detailed Implementation

[0035] To better understand the above technical solutions, exemplary embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0036] Figure 1 This is a schematic diagram of the charging mechanism of this application. Figure 2 for Figure 1 Please refer to the assembly structure diagram. Figure 1 , Figure 2 A charging mechanism 101 for charging cleaning equipment includes a base module 10, a slider module 20, and a charging module 30. The base module 10 is used for fixed installation and includes a first transition surface 11 perpendicular to a first direction X. The slider module 20 is mounted on the first transition surface 11, and the end of the slider module 20 facing away from the base module 10 forms a second transition surface 221. The charging module 30 is mounted on the second transition surface 221, and the end of the charging module 30 facing away from the slider module 20 is provided with a first charging plug 31.

[0037] The slider module 20 and the base module 10 are elastically connected by a first elastic body 50, which is set perpendicular to the first direction X, so that the relative position of the second transition surface 221 relative to the first transition surface 11 is elastically adjustable in the projection plane perpendicular to the first direction X. The charging module 30 and the slider module 20 are elastically connected by a plurality of third elastic bodies 70, which are set perpendicular to the second transition surface 221, so that the relative angle of the first charging plug 31 relative to the second transition surface 221 is elastically adjustable.

[0038] Overall, in order to enable the first charging plug in the charging mechanism to cope with the complex working conditions of positioning posture deviation of the cleaning equipment during recharging, this embodiment sets the relative angle of the first charging plug with respect to the second adapter surface on which it is mounted to be elastically adjustable. At the same time, the second adapter surface is set to be elastically adjustable in relative planar position with respect to the base module on which it is mounted. This allows the first charging plug to accurately dock with the second charging plug of the cleaning equipment under different positioning postures. The first charging plug is, for example, a male charging tail plug, and the second charging plug is, for example, a female charging tail plug.

[0039] Specifically, along the first direction, the charging mechanism includes a base module, a slider module, and a charging module arranged sequentially. It is understood that the base module is used for fixed installation, for example, the base module can be fixedly installed on a cleaning base station. Then, the slider module is installed on the base module, and the charging module is installed on the slider module. The end of the base module facing the slider module forms a first transition surface, which is arranged perpendicular to the first direction. The end of the slider module facing the charging module has a second transition surface, and the charging module is specifically installed on the second transition surface.

[0040] For details, please refer to Figure 2 The charging module and the second adapter surface are elastically connected by a number of third elastic bodies. The third elastic bodies are set perpendicular to the second adapter surface. For example, there are four third elastic bodies arranged in a square on the second adapter surface. Thus, it can be understood that the relative angle between the first charging plug of the charging module and the second adapter surface is elastically adjustable.

[0041] See also Figure 1 In this embodiment, by setting a first elastic body perpendicular to the first direction between the slider module and the base module, the second transition surface can be configured to have an elastically adjustable relative position to the first transition surface in the two-dimensional plane where the first transition surface of the base module is located.

[0042] Specifically, the elastic adjustability of the second transition surface in two dimensions within a two-dimensional plane (i.e., the plane containing the first transition surface): On the one hand, such as Figure 1 As shown, in this embodiment, only a pair of first elastic bodies along the second direction (the second direction is perpendicular to the first direction) can be provided between the slider module and the base module. In this way, the relative position of the second transition surface in one dimension of the two-dimensional plane can be elastically adjusted by means of the first elastic bodies. Then, in another dimension of the two-dimensional plane, this embodiment can achieve the relative position of the second transition surface elastically adjustable by means of the structural settings of the slider module itself (see the description of the following embodiment).

[0043] On the other hand, it can be understood that in this embodiment, a pair of first elastic bodies along the second direction and a pair of first elastic bodies along the third direction can be provided between the slider module and the base module. In this way, the elastic adjustment of the second transition surface in two dimensions in the two-dimensional plane can be achieved by means of the first elastic bodies provided in the two directions.

[0044] Furthermore, it is understood that regarding the relative relationship between the first and second transition surfaces, the second transition surface may be specifically arranged parallel to the first transition surface; of course, in other specific embodiments, the second transition surface may also be arranged non-parallel to the first transition surface, and this embodiment does not impose any restrictions on this.

[0045] Regarding the "elastically adjustable relative position" mentioned above, it should be understood as follows: when subjected to an external force, the external force will force the relative position of the second transition surface relative to the first transition surface to change; then, after the external force disappears, under the action of the elastic restoring force, the second transition surface returns to its original position relative to the first transition surface; "elastically adjustable relative angle" is similar to the above and will not be repeated.

[0046] Wherein, the first direction X is, for example, the docking direction of the two charging plugs; in actual use, the second direction Y is, for example, a vertical direction; and the third direction Z is, for example, a horizontal direction. Figure 3 , Figure 5 for Figure 1 A top-view structural diagram. Figure 6 , Figure 7 for Figure 1 As shown in the side view diagram, the first charging plug can be adjusted by an angle M to the left and right, and to the angle M to the up and down relative to the second adapter surface. The specific value of the angle M can be determined according to actual needs, such as 5 degrees.

[0047] In one possible implementation, the slider module 20 includes a first slider 21 and a second slider 22, which are stacked along a first direction X. The first slider 21 is close to the base module 10, and the second slider 22 is close to the charging module 30. The first slider 21 is elastically connected to the base module 10 by a first elastic body 50, which is arranged along a second direction Y, so that the position of the first slider 21 relative to the first transition surface 11 along the second direction Y is elastically adjustable. The second slider 22 is elastically connected to the first slider 21 by a second elastic body 60, which is arranged along a third direction Z, so that the position of the second slider 22 relative to the first slider 21 along the third direction Z is elastically adjustable. Both the second direction Y and the third direction Z are perpendicular to the first direction X.

[0048] The slider module in this embodiment includes two sliders, namely a first slider and a second slider. The two sliders are stacked along a first direction. The slider closer to the base module is defined as the first slider, and the slider farther from the base module and closer to the charging module is defined as the second slider, so as to distinguish them.

[0049] Among them, see Figure 1 , Figure 2Along the second direction, the first slider is elastically connected to the base module, and then along the third direction, the second slider is elastically connected to the first slider. The second transition surface mentioned above is specifically the end face of the second slider facing the charging module. Thus, it can be understood that, by means of the elastic connection of the two sliders in the slider module, this embodiment can achieve the position of the second transition surface in two dimensions of the two-dimensional plane is elastically adjustable.

[0050] Specifically, a pair of first elastic bodies can be provided between the first slider and the base module, with the first elastic bodies extending along a second direction. Then, a pair of second elastic bodies can be provided between the second slider and the first slider, with the second elastic bodies extending along a third direction.

[0051] As can be seen, this embodiment utilizes the elastic connection of two sliders in the slider module, so that the first slider connected to the base module can be equipped with only a pair of first elastic bodies, resulting in a simple structure that is easy to implement.

[0052] The second direction Y and the third direction Z can be set perpendicularly, for example. That is to say, based on the first direction being perpendicular to the first transition surface, the second direction and the third direction are both perpendicular to the first direction, and the second direction and the third direction are perpendicular to each other.

[0053] Regarding the specific structure of the first elastic body 50 and the second elastic body 60, in one possible embodiment, the first elastic body 50 includes a first guide shaft 51 and a first spring 52. The first guide shaft 51 extends along the second direction Y and passes through the first slider 21. Both ends of the first guide shaft 51 are fixed to the base module 10. The portion of the first guide shaft 51 that extends out of the first slider 21 is covered by the first spring 52. The two ends of the first spring 52 abut against the first slider 21 and the base module 10, respectively. The second elastic body 60 includes a second guide shaft 61 and a second spring 62. The second guide shaft 61 extends along the third direction Z and passes through the second slider 22. Both ends of the second guide shaft 61 are fixed to the first slider 21. The portion of the second guide shaft 61 that extends out of the second slider 22 is covered by the second spring 62. The two ends of the second spring 62 abut against the second slider 22 and the first slider 21, respectively.

[0054] That is, in this embodiment, the elastomer can be configured as a guide shaft outer spring.

[0055] Specifically, see Figure 2 , Figure 6For example, the first elastic body includes a first guide shaft and a first spring. The first guide shaft extends along a second direction and its two ends pass through the first slider. Then, the two ends of the first guide shaft are fixed to the base module. The part of the first guide shaft that passes through the first slider is provided with a first spring. The two ends of the first spring abut against the first slider and the base module, respectively. In this way, it can be understood that the position of the first slider relative to the base module or the first transition surface can be elastically adjusted along the second direction.

[0056] Continue reading Figure 2 , Figure 3 For example, the second elastic body includes a second guide shaft and a second spring. The second guide shaft extends in a third direction and its two ends pass through the second slider. Then, the two ends of the second guide shaft are fixed to the first slider. The part of the second guide shaft that passes through the second slider is provided with a second spring. The two ends of the second spring abut against the first slider and the second slider, respectively. In this way, it can be understood that the position of the second slider relative to the first slider can be elastically adjusted in a third direction.

[0057] In one specific embodiment, the first slider 21 is provided with a first linear bearing 214 at the end through which the first guide shaft 51 passes, and the second slider 22 is provided with a second linear bearing 222 at the end through which the second guide shaft 61 passes.

[0058] See Figure 1 , Figure 2 In order to reduce the sliding resistance of the first slider and the second slider, this embodiment can specifically set a first linear bearing at the end of the first guide shaft of the first slider and a second linear bearing at the end of the second guide shaft of the second slider. In this way, the slider can slide smoothly on the guide shaft by means of linear bearings, thereby reducing sliding resistance.

[0059] Regarding the fixed installation of the first guide shaft 51 and the second guide shaft 61, in one specific embodiment, at the end position corresponding to the first guide shaft 51, the base module 10 is provided with a first boss 12, and a first opening groove 13 is provided on the top of the first boss 12 and on the side facing the first guide shaft 51. The first pressure cover 14 is used to fasten to the first boss 12 after the end of the first guide shaft 51 is placed in the first opening groove 13, so as to fix the end of the first guide shaft 51 to the base module 10. At the end position corresponding to the second guide shaft 61, the first slider 21 is provided with a second boss, and a second opening groove is provided on the top of the second boss and on the side facing the second guide shaft 61. The second pressure cap 213 is used to fasten to the second boss after the end of the second guide shaft 61 is placed in the second opening groove, so as to fix the end of the second guide shaft 61 to the first slider 21.

[0060] In this embodiment, the first guide shaft and the second guide shaft are fixedly installed by means of the first boss and the second boss, respectively.

[0061] The base module has a pair of first bosses at both ends of the first guide shaft. The first bosses protrude from the first transition surface in a first direction. The top of the first boss and the side facing the first guide shaft have a first opening groove. After the end of the first guide shaft is placed in the first opening groove, it is fastened to the first boss with a first pressure cap. In this way, the end of the first guide shaft can be fixed to the base module, and the installation of the first guide shaft is simple.

[0062] The installation of the second guide shaft is similar to that of the first guide shaft, and will not be described in detail here.

[0063] Regarding the charging module 30, in one possible implementation, the charging module 30 includes a fixing block 32 that is fixedly installed with the first charging plug 31, and the fixing block 32 is disposed toward the second adapter surface 221. The third elastic body 70 includes a connecting screw 71 and a third spring 72. The connecting screw 71 is used to fasten to the second transition surface 221. The fixing block 32 is provided with a transition through hole 321 through which the screw of the connecting screw 71 passes. The surface of the fixing block 32 facing away from the slider module 20 is provided with a transition groove 322, which is used to support the nut of the connecting screw 71. The third spring 72 is sleeved on the screw of the connecting screw 71. The two ends of the third spring 72 abut against the second transition surface 221 and the fixing block 32, respectively. Furthermore, the diameter of the transition through hole 321 is larger than the diameter of the screw, and the diameter of the transition groove 322 is larger than the diameter of the nut.

[0064] This embodiment provides a specific structure for the installation of the charging module and the slider module.

[0065] Specifically, the charging module includes a first charging plug and a fixing block. The fixing block is located on the side of the first charging plug facing the slider module or the second adapter surface. The fixing block and the first charging plug are fastened together, for example, by fixing screws 33.

[0066] Specifically, the third elastic body includes a connecting screw and a third spring; wherein, the connecting screw passes through the adapter through hole of the fixing block and the third spring in sequence and is screwed into the second adapter surface and is set perpendicular to the second adapter surface; the surface of the fixing block facing away from the slider module is provided with an adapter groove for bearing the nut of the connecting screw; then, the first charging plug is fastened to the fixing block by the fixing screw, thereby completing the elastic installation of the charging module and the slider module.

[0067] In this embodiment, the diameter of the adapter through hole is larger than the diameter of the screw, and the diameter of the adapter groove is larger than the diameter of the nut. In this way, the relative angle between the first charging plug and the second adapter surface can be elastically adjusted.

[0068] In addition, see Figure 3 , Figure 4 In this embodiment, a receiving groove 311 can also be formed on the surface of the first charging plug facing the fixing block. The receiving groove is opposite to the projection of the adapter groove of the fixing block. In this way, with the help of the space provided by the receiving groove, the first charging plug can have an elastic margin perpendicular to the second adapter surface.

[0069] Specifically, before the first charging plug is subjected to external force, the third spring is in a compressed state to push the fixing block and the second adapter surface apart by a predetermined distance. In this state, the nut of the connecting screw abuts against the adapter groove of the fixing block. At this time, it can be understood that if an external force is applied to the first charging plug, the angle of the first charging plug relative to the second adapter surface can be changed by the allowable space between the adapter through hole and the connecting screw, and the allowable space between the adapter groove and the connecting screw nut. After the external force disappears, the first charging plug can return to its original state under the action of the elastic restoring force of the third spring.

[0070] In one possible implementation, the charging mechanism 101 further includes a detection feedback module 40, which is installed on the slider module 20. The detection feedback module 40 includes a detection body 41 and a detection contact 42. The detection body 41 is fixedly installed on the slider module 20, and the detection contact 42 is elastically telescopically installed on the detection body 41 along the vertical direction of the second transition surface 221. When the detection body 41 is fixedly installed on the slider module 20, the detection contact 42 protrudes relative to the second adapter surface 221; and the detection body 41 and the detection contact 42 are configured such that when the first charging plug 31 is plugged into the second charging plug 200 provided on the cleaning device, the detection contact 42 is triggered by the pressure of the charging module 30 to activate the detection body 41.

[0071] Considering the stability and safety of the first charging plug and the second charging plug of the cleaning device during plug-in charging, this embodiment also sets a detection feedback module in the slider module. With the help of the elastic margin of the first charging plug perpendicular to the second adapter surface, the detection feedback module can ensure the stability of the two charging plugs plug-in.

[0072] Specifically, the detection feedback module includes a detection body and a detection contact. The detection body is fixed to the slider module, and the detection contact is elastically and extendably mounted on the detection body along the vertical direction of the second transition surface. Furthermore, the detection contact protrudes from the second transition surface. (See attached image) Figure 3In this way, when the first charging plug is inserted into the second charging plug of the cleaning device, the first charging plug will elastically retract towards the slider module under the action of the second charging plug. At this time, the first charging plug will squeeze the detection contact to retract synchronously. Then, the retracted detection contact will trigger the detection body, and the detection body will generate a trigger signal. Thus, the generation of the trigger signal can confirm that the two charging plugs are in a stable insertion state.

[0073] That is, for example, charging of the two charging plugs will only be started when the trigger signal mentioned above is detected, and charging of the two charging plugs will be interrupted when the trigger signal disappears to ensure charging safety.

[0074] In one specific embodiment, a pair of detection feedback modules 40 are provided at both ends of the slider module 20 along the second direction Y or at both ends of the third direction Z. The slider module 20 is provided with a bearing groove 23 for mounting the detection feedback modules 40. The second direction Y and the third direction Z are both perpendicular to the first direction X. The detection body 41 includes a first housing 411 and a second housing 412 that are mounted together along the first direction X. The second housing 412 is close to the charging module 30. The detection contact 42 extends along the first direction X and passes through the second housing 412. A fourth spring 414 is provided between the end of the detection contact 42 facing the first housing 411 and the first housing 411. The detection contact 42 is engaged with the inner side of the second housing 412 by a limiting flange 421, so that the detection contact 42 is elastically extended and retracted in the vertical direction of the second transition surface 211 and mounted on the detection body 41. The first housing 411 is equipped with an optocoupler module 413, and the end of the detection contact 42 facing the first housing 411 is provided with a trigger piece 422 for triggering the optocoupler module 413, so that the detection contact 42 triggers the optocoupler module 413 through the trigger piece 422 due to the pressure of the charging module 30.

[0075] In this embodiment, the slider module can be configured with a pair of detection feedback modules along the second or third direction to improve the detection accuracy of the detection feedback modules; wherein, the slider module can specifically install the aforementioned detection feedback modules through the bearing groove.

[0076] In this embodiment, the detection body specifically includes a first housing and a second housing that are mated together. The detection contact passes through the second housing and is elastically engaged with the second housing by a fourth spring and a limiting flange. In this way, the detection contact is installed on the detection body in an elastic telescoping direction along the vertical direction of the second transition surface.

[0077] Then, in this embodiment, an optocoupler module can be installed in the first housing. The detection contact is provided with a trigger plate for triggering the optocoupler module. When the detection contact is retracted relative to the detection body, the trigger plate on it can trigger the optocoupler module so that the optocoupler module generates the above-mentioned trigger signal.
