Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cleaning equipment, and particularly to a bracket structure, a charging base, and a cleaning equipment. Background Art
[0002] Traditional cleaning equipment generally includes a walking body and a charging base. The walking body walks on the surface to be cleaned and performs cleaning operations. When the energy of the walking body is insufficient, the walking body receives signals with different codes emitted by the charging base and continuously adjusts its own position according to the received signals with different codes, so as to be able to return to the position where the charging base is located and charge.
[0003] Specifically, the charging base has a plurality of main signal sources that emit main signals, and the walking body has a signal receiving member that can receive the main signals emitted by each main signal source. Since the main signals emitted by the plurality of main signal sources are easily interfered with each other, the signal receiving member cannot correspond the received main signal to the main signal source that emits the main signal, and further, the walking body cannot be accurately positioned, resulting in the charging failure of the walking body. Summary of the Invention
[0004] Based on this, in view of the problem that the main signals are easily interfered with each other, it is necessary to provide a bracket structure, a charging base, and a cleaning equipment in which the main signals are not easily interfered with.
[0005] A bracket structure includes:
[0006] a bracket main body, and
[0007] at least two main signal sources, which are arranged on the bracket main body at intervals along a first direction;
[0008] wherein, at least two groups of main anti-interference walls are configured to be arranged on the bracket main body at intervals along the first direction; each group of the main anti-interference walls is located on the signal emission side of each main signal source and provides a signal transmission channel for the corresponding main signal source;
[0009] Any two adjacent signal transmission channels do not overlap in their respective signal emission directions.
[0010] In one embodiment, each group of the main anti-interference walls includes a first sub-wall and a second sub-wall arranged at intervals along the first direction, and both the first sub-wall and the second sub-wall extend along a direction intersecting with the first direction, and the space between them is jointly defined as the signal transmission channel.
[0011] In one embodiment, the first sub-wall is a straight wall parallel to the center line of the corresponding main signal source, and the second sub-wall is a sloped wall inclined relative to the center line of the corresponding main signal source, and the distance between the straight wall and the sloped wall gradually increases along the signal transmission direction of the corresponding main signal source.
[0012] In one embodiment, there are two main signal sources, and the straight line where the straight wall in each group of the main anti-interference walls is located is offset from the center line of the main signal source where it is located in a direction away from the adjacent main signal source.
[0013] In one embodiment, the bracket body includes at least two sets of first anti-interference plates and at least two sets of second anti-interference plates, and one set of the first anti-interference plates and one set of the second anti-interference plates form a set of the main anti-interference walls;
[0014] Each group of the first anti-interference boards includes at least two first sub-boards spaced apart along the signal transmission direction of the corresponding main signal source, and each group of the second anti-interference boards includes at least two second sub-boards spaced apart along the signal transmission direction of the corresponding main signal source;
[0015] All the first sub-boards in each group of the first anti-interference boards are adjacent to one end of the second anti-interference boards in the group to form the first sub-wall, and all the second sub-boards in each group of the second anti-interference boards are adjacent to one end of the first anti-interference boards in the group to form the second sub-wall.
[0016] In one embodiment, the bracket body further includes a blocking plate cooperating with each group of the main anti-interference walls, and the two blocking plates are respectively sealed on the sides of all the first anti-interference plates and all the second anti-interference plates in the same group that are away from each other;
[0017] In each group of the main anti-interference walls, the first sub-board and the second sub-board are paired along the first direction, and the two adjacent pairs of the first sub-board and the second sub-board and the part of the blocking plate connected therebetween jointly define a reflection space connected to the signal transmission channel.
[0018] In one embodiment, each group of the main anti-interference walls further includes a third sub-wall connected between the first sub-wall and the second sub-wall, and the support structure further includes at least one group of third anti-interference boards, and each group of the third anti-interference boards includes at least two third sub-boards spaced apart along the signal transmission direction of the corresponding main signal source;
[0019] Among them, each of the third sub-boards in the same group is connected between the first sub-board and the second sub-board along the first direction, and they jointly enclose an exit opening. All the exit openings in each group of the main anti-interference walls jointly penetrate to form the signal transmission channel.

Each group of main anti-interference walls is located on the signal emission side of each main signal source and provides a signal transmission channel for the corresponding main signal source. Since any two adjacent signal transmission channels do not overlap in their respective signal emission directions, therefore, the main signals output by any two adjacent main signals through their respective signal transmission channels will not overlap and interfere with each other. Thus, the walking body can accurately locate according to the received main signal, and thus can be successfully charged. Description of the Drawings

[0044] Please refer to Figure 1 , this application provides a cleaning device, which can be a floor washer, a sweeping and mopping integrated machine, a wet vacuum cleaner, etc., can be a household cleaning device, an industrial cleaning device or a commercial cleaning device, can be a handheld cleaning device or an automatic cleaning device, and the specific application method is not limited. In the example, the cleaning device includes a charging base 1 and a walking body. When the walking body walks on the surface to be cleaned, it is used to perform a cleaning operation on the surface to be cleaned, and the charging base 1 is used to charge the walking body.
[0045] Please also refer to Figure 2 and Figure 3 , wherein, the charging base 1 includes a base body 20, a control panel 30 and a bracket structure 10. The base body 20 has a receiving cavity 21, and a main emission port 23 communicating with the receiving cavity 21 is provided on the base body 20. The control panel 30 and the bracket structure 10 are both connected to the receiving cavity 21 of the base body 20, and the bracket structure 10 emits signals outward through the main emission port 23. The walking body is configured to form a signal receiving member, and the signal receiving member is configured to receive the signals emitted by the bracket structure 10 and continuously adjust its own position according to the received signals. A first contact is also provided on the base body 20, and a second contact is provided on the walking body. The walking body adjusts its own position so that the first contact can be aligned with and connected to the second contact, and then the charging base 1 can charge the walking body.
[0046] Please also refer to Figure 5 , specifically, the bracket structure 10 includes a bracket body 11 and at least two main signal sources 13. All the main signal sources 13 are arranged on the bracket body 11 at intervals along a first direction. Among them, at least two groups of main anti-interference walls 111 are arranged on the bracket body 11 at intervals along the first direction. All groups of main anti-interference walls 111 correspond to all the main signal sources 13 one by one. Each group of main anti-interference walls 111 is located on the signal emission side of each main signal source 13 and provides a signal transmission channel 112 for the corresponding main signal source 13. In addition, any two adjacent signal transmission channels 112 do not overlap in their respective signal emission directions.
[0047] Understandably, each main signal source 13 is a position signal source. Each main signal source 13 is electrically connected to the control panel 30. The control panel 30 is used to control each main signal source 13 to emit a main signal. The main signal sent by each main signal source 13 is sequentially sent to the outside through the corresponding signal transmission channel 112 and the main emission port 23 on the seat body 20. When the walking body walks to the near field, the signal receiving member is used to receive the main signal output by each main signal source 13. Understandably, the main signal is a near-field signal.
[0048] Wherein, "near field" refers to the area range relatively close to the charging stand 1. The main signals emitted by all the main signal sources 13 can completely cover the near field and be received by the walking body walking to the near field. Moreover, the encoding of the main signal emitted by each main signal source 13 is different. The walking body can judge the relative distance between itself and the charging stand 1 according to the received main signals with different encodings and continuously adjust to make the first contact point and the second contact point align.
[0049] In the traditional charging stand 1, two adjacent signal transmission channels 112 are prone to overlap and interfere with each other in their respective signal emission directions, resulting in the signal receiving member being unable to accurately judge the actual position of the positioning body based on all the received main signals, and further resulting in the second contact point on the positioning body being unable to align with the first contact point on the seat body 20.
[0050] In this application, since any two adjacent signal transmission channels 112 do not coincide in their respective signal emission directions, therefore, the main signals emitted by any two adjacent signal transmission channels 112 will not overlap and interfere with each other in the near field. Thus, the positioning body can accurately judge its own position relative to the charging stand 1, so that the positioning body can accurately align and successfully charge.
[0051] Please refer to again Figure 2 and Figure 5 , preferably, the first direction is the longitudinal direction of the bracket body 11 (such as Figure 2 the direction indicated by the arrow a in Figure 2Each set of primary anti-interference walls 111 includes a first sub-wall 1112 and a second sub-wall 1114 arranged along a first direction. Both the first sub-wall 1112 and the second sub-wall 1114 extend in a direction intersecting the first direction, and the space between them defines a signal transmission channel 112. It is understood that the signal transmission channel 112 defined by the first sub-wall 1112 and the second sub-wall 1114 has a simpler structure, thereby reducing the difficulty of setting up the charging station 1. It is understood that the first sub-wall 1112 and the second sub-wall 1114 can extend in the same or different directions.
[0052] Furthermore, the first sub-wall 1112 is a straight wall parallel to the center line of the corresponding main signal source 13, and the second sub-wall 1114 is a sloped wall inclined relative to the center line of the corresponding main signal source 13. The distance between the straight wall and the sloped wall gradually increases along the signal transmission direction of the corresponding main signal source 13. In this way, in the signal transmission direction of each signal transmission channel 112, the coverage area of the main signal emitted by the main signal source 13 corresponding to each signal transmission channel 112 gradually increases, and thus, the two signal sources can more comprehensively cover the near field. Therefore, the coverage blind area of the main signal in the near field is reduced, so the positioning accuracy of the positioning subject can be effectively improved. Specifically, the straight walls of the two groups of main anti-interference walls 111 are symmetrically arranged about the center line of the bracket body 11, and the sloped walls of the two groups of main anti-interference walls 111 are also symmetrically arranged about the center line of the bracket body 11.
[0053] Furthermore, the straight line where the straight wall in each group of main anti-interference walls 111 is located is offset relative to the center line of the main signal source 13 where the straight wall is located, in a direction away from the adjacent main signal source 13. That is to say, in each group of main anti-interference walls 111, the straight wall is set away from the other main signal source 13 relative to the center line of the main signal source 13 corresponding to it. Therefore, the main signals output by the two adjacent main signal sources 13 through the corresponding signal transmission channels 112 are mutually divergent, thereby preventing the main signals emitted by the two main signal sources 13 from overlapping each other. Moreover, under this setting, the possibility of each main signal source 13 being reflected by the corresponding straight wall and inclined wall to the area covered by the main signal emitted by another adjacent main signal source 13 is smaller, thereby helping to improve the positioning accuracy of the entire walking body.
[0054] In one embodiment, the bracket body 11 further includes a top plate 115, a bottom plate 116, and a back plate 117 connected between the top plate 115 and the bottom plate 116. The top plate 115 and the bottom plate 116 are spaced apart along a third direction perpendicular to the first direction and the second direction. The back plate 117 is located on the backlight side of all the main signal sources 13 and is used to support all the main signal sources 13. Specifically, a first buckle 1172 and a second buckle 1152 are respectively provided on the back plate 117 and the top plate 115, and a first slot 31 and a second slot 33 are provided on the control panel 30. The first buckle 1172 is engaged with the first slot 31, and the second buckle 1152 is engaged with the second slot 33, so as to realize the connection between the top plate 115 and the back plate 117 and the control panel 30. Preferably, the third direction is the thickness direction of the bracket body 11 (such as Figure 2 the direction indicated by the arrow c in
[0055] Please refer to Figure 4 and Figure 6 together. The bracket body 11 further includes at least two groups of first anti-interference plates 113 and at least two groups of second anti-interference plates 114. Each group of first anti-interference plates 113 and each group of second anti-interference plates 114 are both located between the bottom plate 116 and the top plate 115, and a group of first anti-interference plates 113 and a group of second anti-interference plates 114 are configured to form a group of main anti-interference walls 111. That is to say, all groups of first anti-interference plates 113 and all groups of second anti-interference plates 114 correspond one by one. A pair of groups of first anti-interference plates 113 and second anti-interference plates 114 form a group of main anti-interference walls 111, and multiple pairs of groups of first anti-interference plates 113 and second anti-interference plates 114 form multiple groups of main anti-interference walls 111.
[0056] Wherein, each group of first anti-interference plates 113 includes at least two first sub-plates 1132 spaced apart along the signal emission direction of the corresponding main signal source 13, and each group of second anti-interference plates 114 includes at least two second sub-plates 1142 spaced apart along the signal emission direction of the corresponding main signal source 13. All the first sub-plates 1132 in each group of first anti-interference plates 113 jointly form a first sub-wall 1112 at one end adjacent to the second anti-interference plate 114 in the same group, and all the second sub-plates 1142 in each group of second anti-interference plates 114 jointly form a second sub-wall 1114 at one end adjacent to the first anti-interference plate 113 in the same group.
[0057] By forming at least two first sub - plates 1132 in each group of first anti - interference plates 113 and at least two second sub - plates 1142 in each group of second anti - interference plates 114, when the main signal transmitted by the main signal source 13 corresponding to each group of first anti - interference plates 113 passes through the corresponding signal transmission channel 112, part of the main signal can be continuously reflected and consumed between at least one first sub - plate 1132 and / or at least one second sub - plate 1142, or be turned into an appropriate angle and emitted from the corresponding signal transmission channel 112. In this way, it is possible to further prevent the mutual interference between the main signals transmitted by two adjacent main signal sources 13.
[0058] Of course, the formation method of the first sub - wall 1112 and the second sub - wall 1114 is not limited to the above one. In some other embodiments, the bracket body 11 may further include at least two first anti - interference plates 113 and at least two second anti - interference plates 114. Each first anti - interference plate and each second anti - interference plate 114 are located between the bottom plate 116 and the top plate 115, and one first anti - interference plate 113 and one second anti - interference plate 114 are paired and configured to form a group of main anti - interference walls 111. Among them, in each pair of the first anti - interference plate 113 and the second anti - interference plate 114, the side of the first anti - interference plate 113 adjacent to the second anti - interference plate 114 jointly constructs the first sub - wall 1112, and the side of the second anti - interference plate 114 adjacent to the first anti - interference plate 113 jointly constructs the second sub - wall 1114.
[0059] Or, in some other embodiments, at least two first sub - plates 1132 may be formed in each group of first anti - interference plates 113, and the second anti - interference plate 114 is a whole - plate structure. A group of first anti - interference plates 113 and one second anti - interference plate 114 are configured to form a group of main anti - interference walls 111. Or, at least two second sub - plates 1142 may be formed in each group of second anti - interference plates 114, and the first anti - interference plate 113 is a whole - plate structure. One first anti - interference plate 113 and a group of second anti - interference plates 114 are configured to form a group of main anti - interference walls 111.
[0060] Furthermore, the bracket body 11 further includes a partition plate 118 cooperating with each group of main anti - interference walls 111. The two partition plates 118 are respectively hermetically arranged on the opposite sides of all the first anti - interference plates 113 and all the second anti - interference plates 114 in the same group. Among them, the first sub - plates 1132 and the second sub - plates 1142 in each group of main anti - interference walls 111 are paired along the first direction. The adjacent two pairs of first sub - plates 1132 and second sub - plates 1142 and the part of the partition plate 118 connecting them jointly define a reflection space communicating with the signal transmission channel 112.
[0061] Understandably, the baffle 118 includes at least two groups, and the at least two groups of baffles 118 correspond one-to-one with at least two groups of main anti-interference walls 111. Each group of baffles 118 includes two baffles 118, and the two baffles 118 are respectively and sealingly arranged on the opposite sides of all the first anti-interference plates 113 and all the second anti-interference plates 114 within the same group. By providing the baffle 118, it is possible to prevent the main signal located in the reflection space from being emitted to the outside through the gaps between two adjacent first sub-plates 1132 of the first anti-interference plate 113 within the same group and the gaps between two adjacent second sub-plates 1142 of the second anti-interference plate 114 within the same group, and causing interference between the main signals of two adjacent main signal sources 13, so that the walking body has better positioning accuracy.
[0062] Preferably, among two adjacent groups of baffles 118, two adjacent baffles 118 are arranged continuously and integrally formed. For example, taking two groups of baffles 118 as an example, each group of baffles 118 includes a first baffle 118 and a second baffle 118, and the second baffle 118 in one group is adjacent to the first baffle 118 in the other group, and the second baffle 118 and the first baffle 118 are arranged continuously and integrally formed. In this way, it helps to improve the structural compactness of the bracket structure 10 in the first direction, and thus the miniaturization of the bracket structure 10 can be achieved.
[0063] Of course, in some other embodiments, among two adjacent groups of baffles 118, two adjacent baffles 118 may also be arranged at intervals.
[0064] In some embodiments, each group of main anti-interference walls 111 further includes a third sub-wall 1116 connected between the first sub-wall 1112 and the second sub-wall 1114. The bracket body 11 further includes at least two groups of third anti-interference plates 119, and all groups of third anti-interference plates 119 correspond one-to-one with all groups of first anti-interference plates 113 and all groups of second anti-interference plates 114. Each group of third anti-interference plates 119 includes at least two third sub-plates 1192 arranged at intervals along the signal emission direction of the corresponding main signal source 13. Among them, each third sub-plate 1192 in the same group is connected between the first sub-plate 1132 and the second sub-plate 1142 along the first direction and jointly encloses an outlet, and all the outlets in each group of main anti-interference walls 111 jointly penetrate to form a signal transmission channel 112.
[0065] Understandably, in each group of main anti-interference walls 111, the first sub-wall 1112 and the second sub-wall 1114 are mainly used to define the boundary of the corresponding main signal source 13 in the first direction, and the third sub-wall 1116 is used to define the lower boundary of the corresponding main signal source 13 in the third direction. By providing the third sub-wall 1116 in each group of main anti-interference walls 111, the main signals emitted by the main signal source 13 corresponding to each group of main anti-interference walls 111 can be highly concentrated and penetrate through all the exit ports together to form a signal transmission channel 112 for emission. Therefore, the concentration of the main signals within the approach field is relatively high, and the signal strength is good, thereby further improving the positioning accuracy of the positioning entity.
[0066] Furthermore, the height of all the third sub-boards 1192 in each group of main anti-interference walls 111 gradually decreases along the signal emission direction in the direction perpendicular to the first direction and the signal emission direction. That is to say, the height of all the third sub-boards 1192 in each group of main anti-interference walls 111 gradually decreases along the third direction in the signal emission direction. In this way, the main signals emitted by each main signal source 13 can be emitted obliquely downward. Specifically, due to the limitation of the size of the walking entity, the installation position of the signal receiving component on the walking entity is usually low in the third direction. By setting the height of all the third sub-boards 1192 in each group of main anti-interference walls 111 to gradually decrease along the third direction in the signal emission direction, when the walking entity walks to the near field, even if the position of the signal receiving component on the walking entity is low, it can still receive the signals emitted by each main signal source 13, thereby ensuring the reliability of charging of the walking entity.
[0067] In some embodiments, each group of main anti-interference walls 111 further includes a fourth sub-wall 1118 connected between the first sub-wall 1112 and the second sub-wall 1114. The third sub-wall 1116 and the fourth sub-wall 1118 are arranged at intervals along the third direction, and the fourth sub-wall 1118 is located above the third sub-wall 1116. The support structure 10 further includes at least two groups of fourth anti-interference plates 121, and all groups of fourth anti-interference plates 121 correspond to all groups of third anti-interference plates 119 one by one. Each group of fourth anti-interference plates 121 includes at least two fourth sub-boards 1212 arranged at intervals along the signal emission direction of the corresponding main signal source 13. Among them, each fourth sub-board 1212 in the same group is connected between the corresponding first sub-board 1132 and the second sub-board 1142 along the first direction, and all the fourth sub-boards 1212 in the corresponding group and all the third sub-boards 1192 correspond to each other in the third direction. The corresponding first sub-board 1132, second sub-board 1142, third sub-board 1192 and fourth sub-board 1212 jointly enclose a circular exit port.
[0068] Understandably, the fourth sub-wall 1118 is used to define the upper bound of the corresponding main signal source 13 in the third direction. By arranging the fourth sub-wall 1118 in each group of main anti-interference walls 111, the signals emitted by the main signal source 13 corresponding to each group of main anti-interference walls 111 can be highly concentrated and penetrate through all the emission ports together to form a signal transmission channel 112 for emission. Therefore, the main signals emitted by each main signal source 13 located in the near field have a high concentration and good signal strength, thereby further improving the positioning accuracy of the positioning body.
[0069] Please refer to again Figure 1 、 Figure 2 and Figure 5 , the bracket structure 10 further includes at least two auxiliary signal sources 15 arranged at intervals along the first direction on the bracket main body 11. The bracket main body 11 is configured to be provided with at least two groups of auxiliary anti-interference walls 122 arranged at intervals along the first direction; each group of auxiliary anti-interference walls 122 is located on the signal emission side of each auxiliary signal source 15 and provides an auxiliary signal transmission channel 127 for the corresponding auxiliary signal source 15. Any adjacent two auxiliary signal transmission channels 127 and / or any adjacent auxiliary signal transmission channels 127 and the signal transmission channel 112 do not coincide in their respective signal emission directions.
[0070] Understandably, each auxiliary signal source 15 is a position signal source. At least two auxiliary emission ports 25 are formed on the seat body 20, and all the auxiliary emission ports 25 are aligned with all the auxiliary signal transmission channels 127 one by one. Each auxiliary signal source 15 is used to emit auxiliary signals, and the auxiliary signals sent by each auxiliary signal source 15 are sequentially sent to the outside through the auxiliary signal transmission channel 127 and the auxiliary emission port 25 corresponding to it, and are received by the signal receiving member on the walking body when the walking body walks to the far field.
[0071] Wherein the "far field" represents a regional range far from the charging base 1. The auxiliary signals emitted by all the auxiliary signal sources 15 can completely cover the far field and are received by the walking body walking to the far field. Moreover, the encodings of the auxiliary signals emitted by each main signal source 13 are different, and the walking body can judge the relative distance between itself and the charging base 1 according to the received auxiliary signals with different encodings and continuously make adjustments. That is to say, when the distance between the walking body and the charging base 1 is far, the signal receiving member on the walking body receives the auxiliary signals emitted by the auxiliary signal source 15. The walking body continuously adjusts its own angle during the process of approaching the charging base 1 according to the received auxiliary signals emitted by different auxiliary signal sources 15 so that the first contact and the second contact tend to be aligned. When the walking body moves to the near field, the walking body receives the main signals emitted by the main signal source 13 and continuously adjusts its own angle and position during the process of approaching the charging base 1, so that the first contact and the second contact can be aligned.
[0072] By setting that any two adjacent auxiliary signal transmission channels 127 do not overlap in their respective signal emission directions, therefore, the auxiliary signals emitted by any two adjacent auxiliary signal transmission channels 127 will not overlap and interfere with each other in the far field. Moreover, the auxiliary signals and the main signals emitted by any two adjacent auxiliary signal transmission channels 127 and the signal transmission channel 112 respectively will not overlap either. Thus, the positioning body can relatively accurately determine its own position relative to the charging base 1, so that the positioning body can align with the charging base 1 and charge.
[0073] Preferably, there are two auxiliary signal sources 15. Two auxiliary signal sources 15 can not only meet the positioning requirements, but also reduce the setting of components of the bracket structure 10. Specifically, the two auxiliary signal sources 15 are symmetrically arranged about the center line of the bracket main body 11 extending in the second direction, and the two auxiliary signal transmission channels 127 corresponding to the two auxiliary signal sources 15 are also symmetrically arranged about the center line of the bracket main body 11.
[0074] Wherein, each group of auxiliary anti-interference walls 122 includes a first auxiliary sub-wall 1221 and a second auxiliary sub-wall 1223. The first auxiliary sub-wall 1221 and the second auxiliary sub-wall 1223 are arranged at intervals along a direction intersecting with the first direction, and the space between them is jointly defined as the auxiliary signal transmission channel 127. It can be understood that the auxiliary signal transmission channel 127 formed jointly by the first auxiliary sub-wall 1221 and the second auxiliary sub-wall 1223 has a simpler structure, which is convenient for reducing the setting difficulty of the charging base 1.
[0075] Furthermore, in each group of auxiliary anti-interference walls 122, the first auxiliary sub-wall 1221 extends along the first direction, the second auxiliary sub-wall 1223 extends along a direction intersecting with the first direction and is inclined relative to the first auxiliary sub-wall 1221, and the distance between the first auxiliary sub-wall 1221 and the second auxiliary sub-wall 1223 gradually increases along the signal emission direction of its corresponding auxiliary signal source 15. In this way, in the signal emission direction of each auxiliary signal transmission channel 127, the coverage area of the auxiliary signal emitted by the auxiliary signal source 15 corresponding to each auxiliary signal transmission channel 127 gradually increases. Furthermore, the two auxiliary signal sources 15 can cover the far field more comprehensively. Therefore, the auxiliary signal blind area in the far field is reduced, so that the positioning accuracy of the positioning body can be effectively improved.
[0076] Preferably, in the first direction, the sum of the angles of the main signal output by all the signal transmission channels 112 and the auxiliary signal output by all the auxiliary signal transmission channels 127 is 180°. Specifically, when the charging base 1 is located indoors, it is generally placed against a wall, and the main signal and the auxiliary signal are emitted in front of it. If the sum of the angles of the main signal output by all the signal transmission channels 112 and the auxiliary signal output by all the auxiliary signal transmission channels 127 is 180°, the area in front of the charging base 1 can be fully covered by the main signal and the auxiliary signal, so that there is no signal blind spot, and therefore, the positioning accuracy of the walking subject is better.
[0077] Specifically, in an embodiment in which there are two auxiliary signal sources 15, the first auxiliary sub-walls 1221 of the two sets of auxiliary anti-interference walls 122 are symmetrically arranged about the center line of the bracket body 11, and the second auxiliary sub-walls 1223 of the two sets of auxiliary anti-interference walls 122 are also symmetrically arranged about the center line of the bracket body 11.
[0078] Furthermore, there are two auxiliary signal sources 15 and two sets of auxiliary anti-interference walls 122. Within each set of auxiliary anti-interference walls 122, the line containing the first auxiliary sub-wall 1221 is offset from the centerline of the auxiliary signal source 15 to which it belongs, away from the centerline of the adjacent auxiliary signal source 15. Thus, within each set of auxiliary anti-interference walls 122, the line containing the first auxiliary sub-wall 1221 is offset from the centerline of the corresponding auxiliary signal source 15 to which it belongs, away from the second auxiliary sub-wall 1223. Therefore, the auxiliary signals output by two adjacent auxiliary signal sources 15 via their corresponding auxiliary signal transmission channels 127 are directed away from each other, thereby preventing the auxiliary signals from the two auxiliary signal sources 15 from overlapping. Furthermore, with this arrangement, the likelihood that each auxiliary signal source 15 will be reflected by its corresponding first auxiliary sub-wall 1221 and second auxiliary sub-wall 1223 into the area covered by the primary signal emitted by the adjacent primary signal source 13, as well as the area covered by the auxiliary signal emitted by the adjacent auxiliary signal source 15, is reduced, thereby improving the positioning accuracy of the entire walking object.
[0079] In one embodiment, the bracket body 11 further includes two first auxiliary anti-interference plates 123 and two second auxiliary anti-interference plates 124. The two first auxiliary anti-interference plates 123 and the two second auxiliary anti-interference plates 124 are both connected between the back plate 117 and the bottom plate 116. One first auxiliary anti-interference plate 123 and one second auxiliary anti-interference plate 124 are configured to form a group of auxiliary anti-interference walls 122. That is to say, all the first auxiliary anti-interference plates 123 and all the second auxiliary anti-interference plates 124 correspond one by one. Each pair of the first auxiliary anti-interference plate 123 and the second auxiliary anti-interference plate 124 forms a group of auxiliary anti-interference walls 122. Multiple pairs of the first auxiliary anti-interference plates 123 and the second anti-interference plates 114 correspond to multiple groups of auxiliary anti-interference walls 122 one by one. Each first auxiliary anti-interference plate 123 is bent relative to the back plate 117 along the second direction. Each second auxiliary anti-interference plate 124 is disposed on the side of the back plate 117 facing away from the control panel 30 and is connected between the top plate 115 and the bottom plate 116. One end of each first auxiliary anti-interference plate 123 adjacent to the second auxiliary anti-interference plate 124 in the same group is configured to form a first auxiliary sub-wall 1221, and one end of each second auxiliary anti-interference plate 124 in the same group as the first auxiliary anti-interference plate 123 is configured to form a second sub-wall 1114.
[0080] Specifically, after the charging base 1 is assembled, the two first auxiliary anti-interference plates 123 are arranged at intervals along the first direction on both sides of the bottom plate 116 and are both connected to the back plate 117 and the bottom plate 116. Each second auxiliary anti-interference plate 124 is arranged at intervals along the second direction with the back plate 117. By providing the two first auxiliary anti-interference plates 123 and the two second auxiliary anti-interference plates 124, when the auxiliary signals emitted by the auxiliary signal source 15 corresponding to each group of the first auxiliary anti-interference plates 123 pass through the corresponding auxiliary signal transmission channels 127, some of the auxiliary signals can be continuously reflected and consumed between the first auxiliary anti-interference plate and the second auxiliary anti-interference plate, or be changed to an appropriate angle and emitted from the corresponding auxiliary signal transmission channel 127. In this way, it is possible to further prevent the auxiliary signals emitted by two adjacent auxiliary signal sources 15 from interfering with each other.
[0081] Preferably, a first mating hole 1161 and second mating holes 1163 distributed on both sides of the first mating hole 1161 are formed in the bottom plate 116. In the second direction, a first mating rib 11321 is formed on the first sub-plate 1132 of each group or some groups of the first anti-interference plates 113 that is farthest from the corresponding main signal source 13. A second mating rib 1242 is provided on each second auxiliary anti-interference plate 124. All the first mating ribs 11321 correspond to all the first mating holes 1161 one by one, and all the second mating ribs 1242 correspond to all the second mating holes 1163 one by one. After the bracket structure 10 is assembled, the first mating rib 11321 is inserted into the corresponding first mating hole 1161 along the third direction, and the second mating rib 1242 is inserted into the corresponding second mating hole 1163 along the third direction, so that the assembly of the bracket structure 10 is more compact and reliable, facilitating the miniaturization of the bracket structure 10.
[0082] In some embodiments, two bosses 125 are provided on the back plate 117, and the two bosses 125 correspond to the two auxiliary signal sources 15 one by one. A groove 1252 is formed by the depression of the top surface of each boss 125 away from the back plate 117. The auxiliary signal part corresponding to each boss 125 is assembled in the corresponding groove 1252, and part of it extends out of the corresponding groove 1252. In addition, two inclined plates 126 are further provided on the top plate 115, and the two inclined plates 126 correspond to the two auxiliary signal sources 15 one by one. Each inclined plate 126 is used to abut the corresponding auxiliary signal light source against the wall of the corresponding groove 1252. Therefore, under the action of the groove 1252 and the inclined plate 126, the auxiliary signal source 15 can be clamped, and it can be ensured that the auxiliary signal emitted by the auxiliary signal source 15 can pass through the corresponding auxiliary signal transmission channel 127.
