Description

Technical Field

[0001] This application relates to the field of toothbrush technology, and more particularly to a charging base and an electric toothbrush. Background Technology

[0002] Electric toothbrushes are widely used in daily life as a personal care household appliance. Electric toothbrushes can be charged wirelessly or wired. Among them, wireless charging electric toothbrushes are widely popular because they do not require an external charging port on the toothbrush itself.

[0003] In related technologies, wireless charging electric toothbrushes include a charging base and a toothbrush body. The charging base contains a charging module that is directly attached to the outer shell, while the toothbrush body is supported on the outside of the outer shell. The toothbrush body is wirelessly charged using the charging module, so the stability of the charging base is particularly important. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a charging base and an electric toothbrush to improve the stability of the charging base.

[0005] This application is achieved through the following technical solution.

[0006] In a first aspect, this application provides a charging base, which includes a housing and a charging assembly. The housing has an internal cavity and a first wall serving as a wall of the cavity. The outer side of the first wall is used to support an electrical device. The charging assembly is disposed within the cavity. The charging assembly includes a counterweight support and a charging module. The charging module is connected to the counterweight support and is located on the side of the counterweight support near the first wall. The charging module is used for wireless connection with the electrical device to supply power to the device.

[0007] In the technical solution of this application embodiment, the charging component is disposed in the receiving cavity, so the outer shell can provide physical protection for the charging component.

[0008] Since the outer side of the first wall is used to support the electrical equipment, and the charging module is located on the side of the counterweight bracket close to the first wall, the charging module can be wirelessly connected to the electrical equipment to supply power to it.

[0009] The presence of the counterweight bracket provides an installation position for the charging module. The weight of the counterweight bracket and the charging module increases the overall weight of the charging base, thus improving its stability. This ensures the stability of the device when placed on the outside of the first wall, guaranteeing stable charging. Furthermore, the heavier charging base facilitates separation when magnetic attraction is required, making separation easier.

[0010] In some embodiments of this application, the housing further includes a second wall, with the first wall and the second wall disposed opposite each other. The charging module abuts against the first wall on the side facing the first wall, and the counterweight bracket abuts against the second wall on the side facing the second wall.

[0011] With this configuration, since the charging module abuts against the first wall and the counterweight bracket abuts against the second wall, the charging component abuts between the first and second walls. This utilizes the clamping force between the first and second walls to fix the charging component, making installation and fixation more convenient.

[0012] In some embodiments of this application, the charging base further includes a guide structure disposed between the counterweight support and the second wall. The guide structure includes a guide groove and a guide protrusion, one of which is disposed on the counterweight support and the other on the second wall. The guide protrusion is used to move along the guide groove and slide out of the guide groove so that the guide protrusion abuts against the surface where the groove opening is located, while simultaneously causing the charging module to abut against the first wall. The guide groove extends along a first direction, and the arrangement direction of the first wall and the second wall intersects with the first direction.

[0013] With this configuration, along the first direction, the counterweight bracket can be moved so that the guide protrusion first enters the guide groove. At this point, the cooperation between the guide groove and the guide protrusion provides guidance. Then, the guide protrusion slides out of the guide groove and moves to the plane where the guide groove is located, thereby achieving contact between the guide protrusion and the plane where the guide groove is located, thus achieving contact between the counterweight bracket and the second wall, and simultaneously causing the charging module to contact the first wall. By moving the counterweight bracket, contact between the counterweight bracket and the second wall, and contact between the charging module and the first wall can be achieved simultaneously, making it convenient to attach the charging component between the first and second walls.

[0014] In some embodiments of this application, along a first direction, the guide groove has a head end and an end end, the wall surface of the end end is an inclined surface, and along the direction from the head end to the end end, the inclined surface extends towards the guide protrusion to the surface where the groove opening of the guide groove is located.

[0015] With this configuration, the inclined surface can guide the guide protrusion inside the guide groove to the plane where the groove opening of the guide groove is located, thereby facilitating the contact between the guide protrusion and the plane where the groove opening of the guide groove is located.

[0016] In some embodiments of this application, the first end penetrates the counterweight support or the second wall along the first direction.

[0017] This design facilitates the guide protrusions entering the guide groove, enabling relative movement between the counterweight bracket and the outer casing.

[0018] In some embodiments of this application, the number of guide structures is at least two, and the at least two guide structures are spaced apart along a second direction, which is perpendicular to the first direction and intersects with the arrangement direction of the first wall and the second wall.

[0019] This design ensures that the counterweight support moves stably inside the casing during its movement, thus guaranteeing the stability of the installation and connection.

[0020] In some embodiments of this application, the housing includes a body portion and an end cap. Along a first direction, the end of the body portion has a first opening, and the end cap is fastened to the first opening to form a receiving cavity. A first wall and a second wall are both located in the body portion, and a guide protrusion is used to enter the guide groove through the first opening.

[0021] This design makes it easy to install the counterweight support into the cavity.

[0022] In some embodiments of this application, the inner side of the first wall has a groove, and the charging module abuts against the bottom of the groove.

[0023] With this design, the groove can limit the charging module in the circumferential direction, which facilitates the installation of the charging module and ensures that the charging module can be installed in place to ensure the stability of subsequent charging.

[0024] In some embodiments of this application, the counterweight support has an internal receiving space; the charging assembly also includes a battery module, which is housed within the receiving space and is electrically connected to the charging module.

[0025] With this setup, the charging module can wirelessly charge the device, while the battery module can power the charging module. The battery module enhances the ease of use of the charging dock.

[0026] In some embodiments of this application, the counterweight support also has a second opening communicating with the receiving space, the second opening facing the first wall. The charging module includes a charging body and a circuit board, the circuit board being disposed at the second opening and connected to the counterweight support, the circuit board being electrically connected to the battery module; the charging body is connected between the circuit board and the first wall, the charging body being electrically connected to the circuit board, and the charging body being used for wireless connection with the power-consuming device.

[0027] This design facilitates the electrical connection between the circuit board and the battery module through the second opening. Furthermore, because the circuit board is positioned at the second opening, it and the counterweight support form a closed space, ensuring the airtightness of the battery module. The charging unit can then be located between the circuit board and the first wall, ensuring a close proximity between the charging unit and the inner side of the first wall. This facilitates wireless connection between the charging unit and external electrical equipment, thereby guaranteeing charging stability.

[0028] In some embodiments of this application, the charging body includes a fixed bracket, a charging coil, and a magnetic accumulator. The fixed bracket is connected to the side of the circuit board facing the first wall, and the charging coil and the magnetic accumulator are both supported on the side of the fixed bracket facing the first wall. The charging coil is used for wireless connection with the electrical device.

[0029] With this setup, the fixed bracket can provide an installation position for the charging coil and the magnetic body. The magnetic body is used to magnetically attract external electrical devices so that the electrical devices and the outer side of the first wall can make close contact, thereby facilitating the wireless charging of the electrical devices by the charging coil.

[0030] Secondly, this application provides an electric toothbrush, including a toothbrush body and a charging base. The charging base is the charging base in any of the above embodiments, and the charging module in the charging base is used for wireless connection with the toothbrush body.

[0031] In the technical solution of this application embodiment, the toothbrush body is charged by the charging module in the charging base. Since the charging base in any of the above embodiments is included, the same beneficial effect can be achieved. Attached Figure Description

[0057] The following is a detailed description of this application.

[0058] Electric toothbrushes are widely used in daily life as a personal care household appliance. Electric toothbrushes can be charged wirelessly or wired. Among them, wireless charging electric toothbrushes are widely popular because they do not require an external charging port on the toothbrush itself.

[0059] Based on this, such as Figure 1 As shown, this application provides an electric toothbrush 100, which includes a toothbrush body 110 and a charging base 120. The charging module 1222 in the charging base 120 is used for wireless connection with the toothbrush body 110.

[0060] The toothbrush body 110 refers to the part that the user can use to brush their teeth. It mainly includes a connected grip and a brush head. The grip has components such as a motor inside. The motor and other components can be connected to the brush head to drive the brush head and other parts to move. So when brushing teeth, the user can hold the grip and drive the brush head to move to complete brushing.

[0061] Additionally, the charging base 120 refers to a device that allows wireless charging of the toothbrush body 110 after it is placed on it. The charging module 1222 mainly includes structures such as the charging coil w2.

[0062] With the above settings, the toothbrush body 110 can be used for brushing teeth, and the charging base 120 can wirelessly charge the toothbrush body 110. Since the charging mode is wireless charging, it is convenient for users to use and improves the ease of use.

[0063] In related technologies, the charging module 1222 is directly attached to the housing 121, while the toothbrush body 110 is supported on the outside of the housing 121, so that the toothbrush body 110 can be wirelessly charged by the charging module 1222. Therefore, the placement stability of the charging base 120 is particularly important.

[0064] Based on this, such as Figures 2-6 As shown, this application provides a charging base 120, which includes a housing 121 and a charging assembly 122. The housing 121 has a receiving cavity a inside, and the housing 121 includes a first wall 12111, which serves as a wall of the receiving cavity a. The outer side of the first wall 12111 is used to support the electrical device. The charging assembly 122 is disposed in the receiving cavity a; the charging assembly 122 includes a counterweight bracket 1221 and a charging module 1222. The charging module 1222 is connected to the counterweight bracket 1221 and is disposed on the side of the counterweight bracket 1221 near the first wall 12111, and is used for wireless connection with the electrical device to supply power to the electrical device.

[0065] The aforementioned electrical device can be the toothbrush body 110, or any other device that requires electricity and is compatible with wireless charging.

[0066] Additionally, the outer casing 121 can be an elliptical structure. Multiple support pads can be provided at the bottom of the outer casing 121 to support it and ensure its stability. For example, four support pads can be provided. A charging surface is located on the upper part of the outer casing 121; that is, the outer wall surface of the first wall 12111 is the charging surface. The charging surface is located on the side of the outer casing 121 opposite to the support pads. Thus, during charging, the device can be placed on the charging surface to complete wireless charging.

[0067] In some examples, the charging coil w2 in the charging module 1222 faces the first wall 12111 and is in contact with the first wall 12111, which can improve the sensitivity of the charging coil w2 to charging the device, thereby facilitating stable charging.

[0068] The material of the counterweight bracket 1221 may include metal, which can ensure the weight of the counterweight bracket 1221.

[0069] In addition, the counterweight support 1221 can be a shell-like structure, such as a square shell, a spherical shell, or other suitable structures. The counterweight support 1221 can be fixed inside the receiving cavity a. For example, the counterweight support 1221 can be connected to the outer shell 121 by means of snap-fit, threaded connection, etc., so as to be stably set inside the receiving cavity a.

[0070] With the above arrangement, the charging component 122 is disposed within the receiving cavity a, so the outer shell 121 can provide physical protection for the charging component 122. Since the outer side of the first wall 12111 is used to support the electrical equipment, and the charging module 1222 is disposed on the side of the counterweight bracket 1221 near the first wall 12111, the charging module 1222 can be wirelessly connected to the electrical equipment to supply power to the electrical equipment.

[0071] Due to the presence of the counterweight bracket 1221, the counterweight bracket 1221 can provide an installation position for the charging module 1222. Since the counterweight bracket 1221 has a certain weight, it can ensure that the overall weight of the counterweight bracket 1221 and the charging module 1222 is increased. This can increase the overall weight of the charging base 120, thereby improving the placement stability of the charging base 120. Thus, after placing the electrical device on the outside of the first wall 12111, the placement stability of the electrical device can be guaranteed, ensuring the stability of charging. Moreover, when separating the electrical device from the charging base 120, since the charging base 120 is relatively heavy, it is easier to separate the electrical device from the charging base 120 when they need to overcome magnetic attraction.

[0072] In some embodiments, such as Figures 3-7 As shown, the counterweight support 1221 has an internal receiving space b. The charging assembly 122 also includes a battery module 1223, which is housed within the receiving space b and is electrically connected to the charging module 1222.

[0073] It is understandable that the charging module 1222 refers to a battery with energy storage capacity, such as a lithium battery or a lead-acid battery.

[0074] In some examples, the battery module 1223 can be electrically connected to an external power source via an interface provided on the charging base 120, thereby charging the battery module 1223 using the power source.

[0075] With the above settings, the charging module 1222 can wirelessly charge the device, while the battery module 1223 can supply power to the charging module 1222. Thus, the power flow is from the battery module 1223 to the charging module 1222 and then to the device. With the battery module 1223, even if there is no external power source, the battery module 1223 can still supply power to the charging module 1222, thereby enabling the charging of the device. This improves the ease of use of the charging base 120.

[0076] In some embodiments, such as Figures 3-7 As shown, the counterweight support 1221 also has a second opening c communicating with the accommodating space b, and the second opening c faces the first wall 12111. The charging module 1222 includes a charging body 12221 and a circuit board 12222. The circuit board 12222 is located at the second opening c and connected to the counterweight support 1221. The circuit board 12222 is electrically connected to the battery module 1223. The charging body 12221 is connected between the circuit board 12222 and the first wall 12111. The charging body 12221 is electrically connected to the circuit board 12222 and is used for wireless connection with the electrical device.

[0077] In some examples, circuit board 12222 can block the second opening c, so that circuit board 12222 and counterweight bracket 1221 can form a closed space, thus ensuring the safety of the battery module 1223.

[0078] It is understood that the charging body 12221 refers to a component that can receive electrical energy from the battery module 1223 and then charge the electrical device. The charging body 12221 should include at least the charging coil w2.

[0079] With the above configuration, the second opening c facilitates the electrical connection between the circuit board 12222 and the battery module 1223. Furthermore, since the circuit board 12222 is located at the second opening c, the circuit board 12222 and the counterweight bracket 1221 can form a relatively enclosed space, ensuring the airtightness of the battery module 1223. The charging body 12221 can be located between the circuit board 12222 and the first wall 12111, ensuring a close proximity between the charging body 12221 and the inner side of the first wall 12111. This facilitates wireless connection between the charging body 12221 and external electrical equipment, thereby ensuring charging stability.

[0080] In some embodiments, such as Figures 3-7As shown, the charging body 12221 includes a fixed bracket w1, a charging coil w2 and a magnetic body w3. The fixed bracket w1 is connected to the side of the circuit board 12222 facing the first wall 12111. The charging coil w2 and the magnetic body w3 are both supported on the side of the fixed bracket w1 facing the first wall 12111. The charging coil w2 is used for wireless connection with the electrical device.

[0081] It is understandable that the mounting bracket w1 is for supporting the charging coil w2 and the magnetic clasp w3, thus achieving an integrated setup of the mounting bracket w1, charging coil w2, and magnetic clasp w3. The charging coil w2 is electrically connected to the circuit board 12222 to receive electrical energy from the battery module 1223, thereby wirelessly charging the device. The magnetic clasp w3 is used to attach the device to the outside of the first wall 12111 to ensure the stability of the device's charging process.

[0082] Among them, the magnetic attractor w3 can be a permanent magnet or an electromagnet, etc.

[0083] In some examples, the fixed bracket w1 has an annular receiving groove formed on the side surface facing the first wall 12111. The charging coil w2 is an annular coil that matches the annular receiving groove. The charging coil w2 is placed in the annular receiving groove to ensure the stability of the charging coil w2. The magnetic body w3 is placed in the middle of the annular receiving groove to perform the function of magnetically attracting electrical equipment.

[0084] Multiple fixing arms can be installed circumferentially on the fixed bracket w1, and these fixing arms can be fixed to the counterweight bracket 1221 using fasteners such as screws. For example, the number of fixing arms can be two, three, four, or five, and the specific number can be selected and set according to the needs.

[0085] With the above configuration, the mounting bracket w1 provides an installation position for the charging coil w2 and the magnetic body w3, integrating the mounting bracket w1, charging coil w2, and magnetic body w3 together. This facilitates the installation and removal of the mounting bracket w1, charging coil w2, and magnetic body w3. The magnetic body w3 is used to magnetically attract external electrical devices, ensuring close contact between the electrical device and the outer side of the first wall 12111, thereby facilitating wireless charging of the electrical device by the charging coil w2.

[0086] In some embodiments, such as Figure 8 As shown, the outer casing 121 also includes a second wall 12112, with the first wall 12111 and the second wall 12112 disposed opposite to each other. The charging module 1222 abuts against the first wall 12111 on the side facing the first wall 12111, and the counterweight bracket 1221 abuts against the second wall 12112 on the side facing the second wall 12112.

[0087] It is understandable that, since the charging module 1222 is connected to the counterweight bracket 1221, the charging module 1222 abuts against the first wall 12111, and the counterweight bracket 1221 abuts against the second wall 12112. This allows the charging module 1222 and the counterweight bracket 1221 to be locked together between the first wall 12111 and the second wall 12112. This not only facilitates the overall fixation of the charging module 1222 and the counterweight bracket 1221, but also, since the charging module 1222 abuts against the inner side of the first wall 12111, while the outer side of the first wall 12111 is used to support the electrical equipment, the distance between the charging module 1222 and the electrical equipment can be reduced, thus facilitating stable charging of the electrical equipment using the charging module 1222.

[0088] In some examples, the charging module 1222 includes a charging body 12221 and a circuit board 12222. When the charging body 12221 includes a fixed bracket w1, a charging coil w2 and a magnetic body w3, the charging coil w2 is used for wireless connection with the device. Therefore, the charging coil w2 is made to abut against the inside of the first wall 12111, which facilitates wireless charging of the device using the charging coil w2.

[0089] With the above configuration, since the charging module 1222 is connected to the counterweight bracket 1221, and the charging module 1222 abuts against the first wall 12111, while the counterweight bracket 1221 abuts against the second wall 12112, the charging assembly 122 abuts against the first wall 12111 and the second wall 12112. This utilizes the clamping force between the first wall 12111 and the second wall 12112 to fix the charging assembly 122, making installation and fixation more convenient. Furthermore, because the charging module 1222 abuts against the first wall 12111, the distance between the charging module 1222 and the electrical device can be closer, facilitating the establishment of a stable electrical connection between the charging module 1222 and the electrical device, thus enabling stable charging of the electrical device using the charging module 1222.

[0090] In some embodiments, such as Figures 8-13 As shown, the charging base 120 also includes a guide structure 123, which is disposed between the counterweight support 1221 and the second wall 12112. The guide structure 123 includes a guide groove 1231 and a guide protrusion 1232. One of the guide groove 1231 and the guide protrusion 1232 is disposed on the counterweight support 1221, and the other is disposed on the second wall 12112. The guide protrusion 1232 is used to move along the guide groove 1231 and slide out of the guide groove 1231, so that the guide protrusion 1232 abuts against the surface where the groove opening of the guide groove 1231 is located, and simultaneously allows the charging module 1222 to abut against the first wall 12111. The guide groove 1231 extends along a first direction X, and the arrangement direction of the first wall 12111 and the second wall 12112 intersects with the first direction X.

[0091] For ease of description, the arrangement direction of the first wall 12111 and the second wall 12112 is defined as the third direction Z, where the third direction Z is the height direction of the charging base 120, and the first direction X is the length direction of the charging base 120. The angle formed by the intersection of the first direction X and the third direction Z can be 75°, 80°, 85° or 90°, etc. For ease of understanding, the first direction X is described as perpendicular to the third direction Z.

[0092] The process of guiding the guide protrusion 1232 using the guide groove 1231 is the movement of the counterweight bracket 1221. After moving into position, the guide protrusion 1232 disengages from the guide groove 1231. At this time, the guide protrusion 1232 abuts against the plane where the groove opening of the guide groove 1231 is located. That is, the counterweight bracket 1221 abuts against the second wall 12112 by the abutment between the guide protrusion 1232 and the plane where the groove opening of the guide groove 1231 is located.

[0093] It is understood that this embodiment includes two solutions, the first being: such as Figures 8-12 As shown, the guide groove 1231 is provided on the counterweight bracket 1221, and the guide protrusion 1232 is provided on the second wall 12112. In this case, the planes containing the guide protrusion 1232 and the guide groove 1231 abut against each other, that is, the surfaces of the guide protrusion 1232 and the counterweight bracket 1221 abut against the first wall 12111. The second type, as shown... Figure 13 As shown, the guide protrusion 1232 is provided on the counterweight bracket 1221, and the guide groove 1231 is provided on the second wall 12112. In this case, the planes where the guide protrusion 1232 and the guide groove 1231 are located abut each other, which means that the inner surfaces of the guide protrusion 1232 and the second wall 12112 abut each other.

[0094] The guide protrusion 1232 can also extend along the first direction X, which makes it easier for the guide protrusion 1232 to move within the guide groove 1231.

[0095] Additionally, it is understandable that when the plane containing the guide protrusion 1232 and the guide groove 1231 abuts, the reason why the charging module 1222 abuts against the inner wall surface of the first wall 12111 is because the guide protrusion 1232 raises the counterweight bracket 1221 as a whole in the third direction Z, and at the same time raises the charging module 1222 in the third direction Z, so that the charging module 1222 can abut against the inner wall surface of the first wall 12111.

[0096] With the above settings, along the first direction X, the counterweight bracket 1221 can be moved so that the guide protrusion 1232 first enters the guide groove 1231. At this time, the guide groove 1231 and the guide protrusion 1232 cooperate to play a guiding role. After moving a certain distance, the guide protrusion 1232 will slide out of the guide groove 1231 and move to the plane where the guide groove 1231 is located, thereby realizing the contact between the guide protrusion 1232 and the plane where the guide groove 1231 is located, so as to realize the contact between the counterweight bracket 1221 and the second wall 12112, and at the same time, the charging module 1222 and the first wall 12111 abut, thereby snapping the charging component 122 between the first wall 12111 and the second wall 12112. This facilitates the snapping and installation of the counterweight bracket 1221.

[0097] In some embodiments, such as Figure 10 , Figure 11 As shown, along the first direction X, the guide groove 1231 has a beginning end h1 and an end end h2. The wall of the end h2 is an inclined surface d. Along the direction from the beginning end h1 to the end h2, the inclined surface d extends towards the guide protrusion 1232 to the surface where the groove of the guide groove 1231 is located.

[0098] It should be explained that the first end h1 of the guide groove 1231 refers to the end that the guide protrusion 1232 first contacts when it enters the guide groove 1231 as it moves along the first direction X. The last end h2 of the guide groove 1231 refers to the end that the guide protrusion 1232 finishes its movement within the guide groove 1231 and is about to leave the guide groove 1231 as it moves along the first direction X.

[0099] The inclined surface d can be an arc-shaped surface or a straight surface, as long as the overall inclination trend of the inclined surface d meets the requirements.

[0100] In addition, it is understood that the wall of the end h2 in this embodiment is an inclined surface d, which should be the peripheral wall of the guide groove 1231. That is, the guide groove 1231 also has a bottom wall, which can be a straight surface extending along the first direction X.

[0101] With the above configuration, when the guide protrusion 1232 moves from the first end h1 along the guide groove 1231 to the last end h2, the inclined surface d at the last end h2 can guide the guide protrusion 1232 toward the plane where the guide groove 1231 is located, thus facilitating the guide protrusion 1232 to leave the guide groove 1231 and abut against the plane where the guide groove 1231 is located. The inclined surface d facilitates the guidance of the guide protrusion 1232 inside the guide groove 1231 to the plane where the groove opening of the guide groove 1231 is located, thus facilitating actual operation.

[0102] In other embodiments, along the first direction X, the guide groove 1231 has a beginning end h1 and an end end h2. The bottom of the guide groove 1231 is a slope, extending towards the end h2 from the beginning end h1 to the surface where the opening of the guide groove 1231 is located. Thus, after the guide protrusion 1232 enters the guide groove 1231, the bottom of the guide groove 1231 can guide the guide protrusion 1232, guiding it into the guide groove 1231 and causing the plane containing the guide protrusion 1232 and the guide groove 1231 to abut. This also facilitates the actual abutment operation.

[0103] In some embodiments, such as Figure 10 , Figure 11 As shown, along the first direction X, the first end h1 penetrates the counterweight bracket 1221 or the second wall 12112.

[0104] In other words, this embodiment includes two schemes. The first scheme is that the guide groove 1231 is set on the counterweight bracket 1221, and the first end h1 penetrates through the counterweight bracket 1221. The second scheme is that the guide groove 1231 is set on the second wall 12112, and the first end h1 penetrates through the second wall 12112.

[0105] With the above configuration, when the guide groove 1231 is set on the counterweight bracket 1221, the first end h1 penetrates through the counterweight bracket 1221. When the guide groove 1231 is set on the second wall 12112, the first end h1 penetrates through the second wall 12112. In this way, the guide protrusion 1232 can enter the guide groove 1231 from the notch at the first end h1, which facilitates the relative movement between the counterweight bracket 1221 and the outer shell 121.

[0106] In some embodiments, such as Figures 10-12 As shown, the number of guide structures 123 is at least two, and the at least two guide structures 123 are arranged at intervals along the second direction Y. The second direction Y is perpendicular to the first direction X and intersects with the arrangement direction of the first wall 12111 and the second wall 12112.

[0107] For ease of understanding, this application will use the example of the first direction X, the second direction Y, and the third direction Z being perpendicular to each other.

[0108] The number of guide structures 123 can be two, three, four, five, or six, etc.

[0109] For example, there are two guide structures 123, which are spaced apart along the second direction Y. This not only ensures the stability of the contact but also allows control over the number of guide structures 123, thereby controlling costs.

[0110] With the above settings, during the movement of the counterweight support 1221, multiple guide structures 123 can guide the counterweight support 1221. Moreover, after the movement is in place, multiple guide protrusions 1232 can abut against the plane where the guide groove 1231 is located. This not only ensures that the counterweight support 1221 moves stably inside the outer shell 121, but also ensures the stability of the abutment after the movement is completed.

[0111] In some embodiments, such as Figure 13 , Figure 14 As shown, the outer casing 121 includes a body portion 1211 and an end cap 1212. Along the first direction X, the end of the body portion 1211 has a first opening e, and the end cap 1212 is fastened to the first opening e to form a receiving cavity a. The first wall 12111 and the second wall 12112 are both located in the body portion 1211, and the guide protrusion 1232 is used to enter the guide groove 1231 through the first opening e.

[0112] It is understandable that the size of the first opening e should be at least large enough to allow the charging component 122 to pass through.

[0113] The main body 1211 and the end cap 1212 can be detachably connected, which facilitates the opening and closing of the first opening e, thereby facilitating the installation and disassembly of the counterweight bracket 1221, and further facilitating the installation and disassembly of the charging module 1222 connected to the counterweight bracket 1221, which in turn facilitates the overall installation and disassembly of the charging assembly 122.

[0114] With the above configuration, when the counterweight bracket 1221 needs to be installed into the receiving cavity a, the end cap 1212 and the main body 1211 can be separated first to open the first opening e. Then, the guide protrusion 1232 enters the guide groove 1231 from the first end h1 through the first opening e. Next, the counterweight bracket 1221 is moved along the direction from the first end h1 to the end h2 until it reaches the end h2. Then, the counterweight bracket 1221 is continued to be pushed to make the guide protrusion 1232 continue to move and operate. The counterweight bracket 1221 is raised as a whole in the third direction Z, so that the charging module 1222 and the inner wall surface of the first wall 12111 can abut against each other, thereby realizing the abutment installation of the counterweight bracket 1221 and the charging module 1222. Then, the end cover 1212 is set at the first opening e to seal the first opening e, so that the charging component 122 is installed in the receiving cavity a, which facilitates actual operation.

[0115] In some embodiments, such as Figure 8 As shown, the inner side of the first wall 12111 has a groove f, and the charging module 1222 abuts against the bottom of the groove f.

[0116] In some examples, the charging module 1222 includes a charging body 12221 and a circuit board 12222. When the charging body 12221 includes a fixing bracket w1, a charging coil w2, and a magnetic attractor w3, at least the charging coil w2 should abut against the bottom of the groove f to facilitate a stable wireless connection between the charging coil w2 and the device. Alternatively, both the charging coil w2 and the magnetic attractor w3 can abut against the bottom of the groove f, which not only facilitates a stable wireless connection between the charging coil w2 and the device but also allows the magnetic attractor w3 to attach to the device.

[0117] The groove f should be matched with the charging module 1222. For example, when the charging coil w2 abuts against the bottom of the groove f, the charging coil w2 is circular and the groove f is also cylindrical.

[0118] With the above configuration, the groove f can limit the charging module 1222 in the circumferential direction, thereby facilitating the stable setting of the charging module 1222 and ensuring the stability of subsequent charging. Moreover, when setting the guide structure 123, after the plane containing the guide protrusion 1232 and the guide groove 1231 abuts, at least a portion of the charging module 1222 can enter the groove f and abut against the bottom of the groove f. At this time, the presence of the groove f can restrict the charging assembly 122 from continuing to move along the first direction X. Therefore, the setting of the groove f can serve as a prompt that the charging assembly 122 has moved into place along the first direction X, which can further improve the convenience of operation and installation.

[0119] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
