[0061] The display pattern of the dot matrix screen A300 is implemented by the dot matrix screen A300 alone, and the display pattern of the dot matrix screen A300 is finally implemented on the top outer surface of the display panel A100, which facilitates human-computer interaction.

[0062] The display pattern of the dot matrix screen A300 can also be achieved by combining the dot matrix screen A300 and the light-emitting component A200.

[0063] It should be noted that the top outer surface of the A100 display panel is glossy and without etching, which enables the luminous patterns to be displayed delicately and without blurring.

[0064] The display device also includes a decorative ring A400, which is connected to the outer periphery of the display panel A100. The decorative ring A400 can shield and protect the light-emitting component A200. The dot matrix screen A300 is exposed at the bottom of the display panel A100 through the annular hole of the decorative ring A400.

[0065] The decorative ring A400 is provided with multiple heat dissipation holes A404, which are evenly arranged around the side wall of the display panel A100. The heat from the heat sink A500 will be evenly dissipated from the bottom of the display panel A100 from the heat dissipation holes A404 to the top of the display panel A100 from bottom to top.

[0066] In this embodiment of the disclosure, the display device further includes a heat sink A500, and the display panel A100 and the heat sink A500 are fastened together to form an enclosing space. The dot matrix screen A300 and the light-emitting component A200 are both disposed within the enclosing space.

[0067] In some embodiments, a decorative ring A400 can be connected between the display panel A100 and the heat sink A500. The decorative ring A400 is connected to the bottom of the display panel A100 and faces the light-emitting component A200. The decorative ring A400 can shield and protect the light-emitting component A200. The dot matrix screen A300 is exposed at the bottom of the display panel A100 through the annular hole of the decorative ring A400.

[0068] The heat sink A500 passes through the annular hole of the decorative ring A400 and is connected to the bottom of the display panel A100. The heat sink A500 is also in direct contact with the dot matrix screen A300 to dissipate heat from the dot matrix screen A300. The heat sink A500 also encloses the dot matrix screen A300 inside the display panel A100, so that the heat sink A500 can dissipate heat from the dot matrix screen A300 while also protecting the dot matrix screen A300.

[0069] When the decorative ring A400 is connected to the bottom of the display panel A100, the outer edge of the decorative ring A400 surrounds the outer surface of the side wall of the display panel A100. The outer edge of the decorative ring A400 is provided with multiple heat dissipation holes A404. The multiple heat dissipation holes A404 are evenly arranged around the side wall of the display panel A100. The heat from the heat sink A500 will be evenly dissipated from the bottom of the display panel A100 from the heat dissipation holes A404 to the top of the display panel A100 from bottom to top.

[0070] In some embodiments, the decorative ring A400 may also be connected to the outer periphery of the display panel A100. The decorative ring A400 surrounds the outer surface of the side wall of the display panel A100, and the outer edge of the decorative ring A400 is provided with a plurality of heat dissipation holes A404. The plurality of heat dissipation holes A404 are evenly arranged around the side wall of the display panel A100, and the heat of the heat sink A500 will be evenly dissipated from the bottom of the display panel A100 from the heat dissipation holes A404 to the top of the display panel A100 from bottom to top.

[0071] Heat sink A500 is connected to the bottom of display panel A100. Heat sink A500 is in direct contact with dot matrix screen A300 to dissipate heat from dot matrix screen A300. Heat sink A500 can also enclose dot matrix screen A300 and light-emitting component A200 inside display panel A100, so that heat sink A500 can dissipate heat from dot matrix screen A300 while protecting dot matrix screen A300 and light-emitting component A200.

[0072] The display device provided in this embodiment includes a display panel A100, a dot matrix screen A300, a light-emitting component A200, a decorative ring A400, and a heat sink A500. Both the dot matrix screen A300 and the light-emitting component A200 are disposed within the display panel A100, with the light-emitting component A200 surrounding the dot matrix screen A300. The display pattern of the dot matrix screen A300 is implemented solely by the dot matrix screen A300, and the display pattern is located on the top outer surface of the display panel A100; or the display pattern of the dot matrix screen A300 is implemented by a combination of the dot matrix screen A300 and the light-emitting component A200, and the display pattern is located on the top outer surface of the display panel A100; the decorative ring A400... A decorative ring A400 is connected to the bottom of display panel A100. It shields and protects the light-emitting component A200, while the dot matrix screen A300 is exposed at the bottom of display panel A100 through the annular hole of the decorative ring A400. The heat sink A500 is connected to the bottom of display panel A100 through the annular hole and contacts the dot matrix screen A300. The outer edge of the decorative ring A400 surrounds the outer surface of the sidewall of display panel A100, and multiple heat dissipation holes A404 are provided on the outer edge of the decorative ring A400. Heat generated by the heat sink A500 is dissipated from the bottom of display panel A100 through the heat dissipation holes A404 to the top of display panel A100. By providing the decorative ring A400 to protect the dot matrix screen A300 and the light-emitting component A200 inside display panel A100, and by providing a ring of evenly distributed heat dissipation holes A404 on the decorative ring A400, heat from the heat sink A500 can be dissipated upwards through the heat dissipation holes A404, reducing heat accumulation.

[0073] In this embodiment of the disclosure, the distance between the light-emitting component A200 and the edge of the display area is less than 1 cm in the top-view projection direction.

[0074] In this embodiment of the disclosure, the display panel A100 is transparent or semi-transparent. Transparency can be understood as the display panel A100 having a high light transmittance, such as a light transmittance greater than or equal to 80%, in which case materials such as glass or acrylic can be used; semi-transparency can be understood as the display panel A100 having a light transmittance that scatters or weakens light, allowing some light to pass through, such as a light transmittance between 30% and 80%, in which case materials such as frosted glass or acrylic can be used.

[0075] In this embodiment, an auxiliary plate A402 extends outward from the outer edge of the decorative ring A400. The auxiliary plate A402 has multiple heat dissipation holes A404. The auxiliary plate A402 also has multiple protrusions A403, with a gap between adjacent protrusions A403 to form a serrated structure on the auxiliary plate A402. Each heat dissipation hole A404 is connected to a corresponding gap, meaning there is one heat dissipation hole A404 between two adjacent protrusions A403. When heat from the heat sink A500 flows out from the bottom of the display panel A100 through the heat dissipation holes A404, the protrusions A403 guide the heat, causing it to dissipate upwards.

[0076] Referring to Figures 5 and 6, Figure 6 is a schematic diagram of the structure of the dot matrix screen of the display device provided in an embodiment of this disclosure; in this embodiment, the dot matrix screen A300 includes a dot matrix screen body A301, a dot matrix screen light-blocking component A302, a light-diffusing film A303, and a first connector A801.

The light-diffusing film A303 is attached to the dot matrix screen light-blocking component A302, and the light-diffusing film A303 is close to the top outer surface of the display panel A100.

[0077] The dot matrix screen body A301 consists of 392 monochrome LEDs arranged in a matrix, with each LED individually controlled by a controller to change the displayed content. The dot matrix screen light-blocking component A302 is a black, opaque structure to reduce light leakage. The light-diffusing film A303 is a semi-transparent film, using gray or dark gray, which, while achieving uniform light distribution for each LED, reduces the contrast difference with the display panel A100, resulting in a more seamless appearance; simultaneously, the internal structure is not visible when the screen is off, and it absorbs some light leakage. It should be noted that this disclosure does not limit the number of monochrome LEDs on the dot matrix screen body A301.

[0078] Meanwhile, a third connection hole is also provided in the display panel A100. The first connector A801 ​​is connected to the first connection hole A3011, the second connection hole A3021 and the third connection hole, so that the dot matrix screen A300 is assembled in the display panel A100.

[0079] Referring to Figures 2 and 7, Figure 7 is a schematic diagram of the connection structure between the display panel and the decorative ring of the display device provided in this embodiment of the present disclosure; in this embodiment of the present disclosure, the display device further includes a second connector A802, a fifth connection hole A501 is provided on the heat sink A500, and a sixth connection hole A130 is provided on the display panel A100.

Heat sink A500 can also enclose dot matrix screen A300 and light-emitting component A200 inside display panel A100, so that heat sink A500 can dissipate heat from dot matrix screen A300 while protecting dot matrix screen A300 and light-emitting component A200.

[0106] In this embodiment of the disclosure, the display panel A100 is transparent or semi-transparent.

[0111] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0112] Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this disclosure. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0113] This disclosure aims to provide an electrode sheet, a first charging section, a second charging section, a charging assembly, and a charging system. The electrode sheet includes a charging segment, which is flat and extends along a first direction. Along the first direction, the length of the charging sheet is greater than the length of the contact piece, and along a second direction, the width of the charging sheet is greater than the width of the contact piece. By setting the charging segment of the electrode sheet to be flat and extending a certain length along the first direction, and by making the width of the electrode sheet in the second direction greater than the width of the contact piece it mates with, this disclosure allows the electrode sheet to be inserted and contact the contact piece along the first direction during charging. Compared to point-to-point contact in related technologies, the contact area between the electrode sheet and the contact piece in this disclosure is larger and has a certain redundancy. Even if the electrode sheet is not fully aligned, it can still make sufficient contact for charging.

[0114] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this disclosure. It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. For example, the first direction X, the second direction Y, and the third direction Z can be mutually perpendicular, and the third direction Z can be, for example, a vertical direction. The first direction X and the second direction Y can be, for example, two mutually perpendicular directions in a horizontal plane.

[0115] Referring to Figure 14, this embodiment provides an electrode sheet B110, which contacts the contact plate of a charging sheet for charging. The electrode sheet B110 can be made of a highly conductive metal, such as copper or silver. The electrode sheet B110 includes a charging segment B111, which is flat and extends along a first direction X, giving it a certain length in that direction. It is understood that the first direction X in this embodiment can be the insertion direction of the electrode sheet B110 during charging. Along the first direction X, the length of the charging segment B111 is greater than the length of the contact plate, and along the second direction Y, the width of the charging segment B111 is greater than the width of the contact plate, thus giving the electrode sheet B110 of this embodiment a larger charging area.

[0116] When charging using the electrode plate B110 of this embodiment, the electrode plate B110 is inserted along the first direction X and contacts the contact plate. Compared with the point-to-point contact in related technologies, the contact area between the electrode plate B110 and the contact plate in this embodiment is larger and has a certain amount of redundancy. Even if the electrode plate B110 is not fully aligned, it can still make full contact for charging.

[0117] In some embodiments, the electrode sheet B110 of this embodiment further includes a guide segment 112, which is connected to the charging segment B111 and is located on the side of the charging segment B111 facing the contact (i.e., the side of the electrode sheet B110 inserted during charging). In the direction away from the charging segment B111, along the second direction Y, the width of the guide segment 112 gradually decreases.

[0118] In this embodiment, by setting the guide section 112, the electrode plate B110 can be guided to cooperate smoothly with the contact plate so that charging can proceed smoothly.

[0119] The electrode sheet B110 in this embodiment also includes a fixing section B113, which is located on one side of the charging section B111 along the second direction Y. The fixing section B113 is connected to other parts to fix the electrode sheet B110.

[0120] For example, the electrode plate B110 in this embodiment further includes an electrode plate wiring segment B114, which is connected to the fixing segment B113 and located on the side of the charging segment B111 away from the guide segment 112 in the first direction X. The electrode plate wiring segment B114 can be connected to an external power source. For example, a through hole can be provided on the electrode plate wiring segment B114, and the charging cable led out from the external power source can be fixed in the through hole, thereby realizing an electrical connection with the electrode plate wiring segment B114.

[0121] In some embodiments, the charging section B111, guiding section B112, fixing section B113, and electrode sheet wiring section B114 of this embodiment are all located in the same plane. With the above arrangement, compared to the bent electrode sheet in the prior art, this embodiment can reduce the size and resistance of the electrode sheet B110.

[0122] Referring to Figure 15, this embodiment also provides a first charging unit B100, which is installed on a first device; exemplarily, the first device B10 can be, for example, a charging pile. The first charging unit B100 cooperates with a second charging unit to perform charging; that is, the first charging unit B100 can charge the second charging unit. The first charging unit B100 includes a first housing B120, and two electrode plates B110 as described above are provided at intervals along the second direction Y inside the first housing B120. One of the two electrode plates B110 is connected to the positive charging wire inside the first device, and the other is connected to the negative charging wire inside the first device. The charging sections B111 of the two electrode plates B110 are respectively located on both sides of the first housing B120 along the second direction Y.

[0123] When the first charging section B100 is charging, it can simultaneously contact the contacts in the second charging section through the charging sections B111 on both sides to perform charging. Due to the use of the aforementioned electrode plate B110, the contact area between the first charging section B100 and the contact plate in this embodiment is larger and has a certain redundancy. Even if the electrode plate B110 is not fully aligned, it can still make full contact for charging.

[0124] In some embodiments, in this embodiment, the electrode plate B110 passes through the first housing B120. It can be understood that part of the electrode plate B110 is located inside the first housing B120, thereby achieving connection and fixation with the first housing B120; the other part is located outside the first housing B120 for charging.

[0125] Please continue referring to Figures 14 and 15. In some embodiments, the electrode sheet of this embodiment is connected to the first housing B120 via a fixing segment B113. The first housing B120 of this embodiment includes a base B121 and a top cover B122. The base B121 is provided with a positioning post B1211, and the electrode sheet B110 is provided with a positioning hole B1131. The positioning hole B1131 is fitted onto the positioning post B1211 for installation and positioning. The base B121 and the top cover B122 are detachably connected, and after the base B121 and the top cover B122 are connected, the electrode sheet B110 can be clamped and fixed. In this embodiment, the base B121 and the top cover B122 can be detachably connected using screws or clips.

[0126] Referring to Figures 16 and 17, this embodiment also provides a second charging unit B200, which is installed on a second device. Exemplarily, the second device can be a device to be charged, such as a lawnmower or a vehicle. The second charging unit B200 cooperates with the first charging unit B100 to charge the second device. The second charging unit B200 includes two charging plates B210 spaced apart along a second direction Y. Each charging plate B210 includes a first clamping plate B211 and a second clamping plate B212 opposite each other along a third direction Z. The first clamping plate B211 and the second clamping plate B212 contact the electrode plate B110 of the first charging unit B100 for charging.

[0127] In this embodiment, the charging plate B210 is configured as a first clip B211 and a second clip B212 facing each other along the third direction Z. During charging, the electrode plate B110 is inserted between the first clip B211 and the second clip B212, and the two surfaces of the electrode plate B110 are in contact with the first clip B211 and the second clip B212 respectively, thereby increasing the contact area, which is beneficial to improving the charging speed and enhancing the user experience.

[0128] Please refer to Figure 17. In this embodiment, both the first clamping piece B211 and the second clamping piece B212 are elastic sheets, and the first clamping piece B211 abuts against the second clamping piece B212. When the electrode sheet B110 is inserted along the first direction X, the first clamping piece B211 and the second clamping piece B212 can be pushed apart. Under the action of their own elastic force, the first clamping piece B211 and the second clamping piece B212 clamp and fix the electrode sheet B110, thereby contacting the two surfaces of the electrode sheet B110 respectively and preventing the electrode sheet B110 from detaching.

[0129] In one possible implementation, the first clip B211 of this embodiment includes a first contact B2113, and the second clip B212 includes a second contact B2123. The charging piece B210 further includes a pressing portion, which is connected to the first contact B2113 and / or the second contact B2123. The pressing portion presses the first contact B2113 and / or the second contact B2123 to make the first contact B2113 contact the second contact B2123.

[0130] This embodiment uses a pressing part to maintain the contact state of the first contact piece B2113 and the second contact piece B2123, thereby preventing the electrode piece B110 from detaching and ensuring normal charging.

[0131] Specifically, the compression part in this embodiment includes a first elastic arm B2111, a first connecting section B2112, a second elastic arm B2121, and a second connecting section B2122.

[0132] Along the third direction Z, the first spring arm B2111 and the second spring arm B2121 are arranged opposite to each other. A first connecting segment B2112 connects the first spring arm B2111 and the first contact piece B2113 and is bent toward the second spring arm B2121. A second contact piece B2123 connects the second spring arm B2121 and the second contact piece B2123 and is bent toward the first spring arm B2111. Both the first contact piece B2113 and the second contact piece B2123 are parallel to the plane formed by the first direction X and the second direction Y, and the first contact piece B2113 abuts against the second contact piece B2123.

[0133] In this embodiment, the dimensions of the first contact piece B2113 and the second contact piece B2123 can be set as needed, so that the electrode piece B110 has a sufficiently large contact area with the first contact piece B2113 and the second contact piece B2123, thereby improving the stability of the charging speed.

[0134] Referring to Figure 16, the second charging unit B200 in this embodiment further includes a second housing B220. A mounting groove B221 is formed within the second housing B220. Two charging pieces B210 are disposed within the mounting groove B221. The mounting groove B221 abuts against the first clamping piece B211 and the second clamping piece B212, keeping them in abutting position. In other words, the first clamping piece B211 and the second clamping piece B212 in this embodiment can abut each other through the limiting effect of the mounting groove B221. Therefore, without the charging piece B210 falling out of the mounting groove B221, both the first clamping piece B211 and the second clamping piece B212 can remain in abutting position.

[0135] Referring to Figure 17, the charging plate B210 in this embodiment further includes a connecting section B213, a clip fixing section B214, and a charging cable welding section B215. The two ends of the connecting section B213 are respectively connected to a first clip B211 and a second clip B212, thus connecting the first clip B211 and the second clip B212 into a single unit. The clip fixing section B214 is disposed on one side of the connecting section B213 along a third direction Z, and is fixedly connected to the mounting groove B221. Exemplarily, this embodiment may have a through hole in the clip fixing section B214 and a fixing hole in the mounting groove B221. A first fastener B230 passes through the through hole and is fixed in the fixing hole, thereby fixing the clip fixing section B214 to the mounting groove B221. The first fastener B230 may be, for example, a screw or a rivet. The charging cable welding section B215 is located at one end of the clamp fixing section B214 opposite to the connecting section B213, and the charging cable welding section B21 is connected to the battery inside the second device B20. For example, the charging cable welding section B215 may have a through hole, and the battery can be fixed in the through hole by a wire, thereby achieving an electrical connection with the charging cable welding section B215.

[0136] Please refer to Figures 18 and 19. This embodiment provides a charging component, including:

[0137] The first charging unit B100 is mounted on the first device B10; for example, the first device B10 can be a charging pile. The first charging unit B100 includes two electrode plates B110 arranged at intervals along the second direction Y. One of the two electrode plates B110 is connected to the positive charging line inside the first device B10, and the other is connected to the negative charging line inside the first device B10.

[0138] The aforementioned second charging unit B200 is mounted on the second device B20. For example, the second device B20 can be a device to be charged, such as a lawnmower or vehicle. The second charging unit B200 includes two charging plates B210 spaced apart along a second direction Y. One of the two charging plates B210 is connected to the positive terminal of the battery inside the second device B20, and the other is connected to the negative terminal of the battery inside the second device B20. Each charging plate B210 includes a first clip B211 and a second clip B212 opposite each other along a third direction Z. The first clip B211 and the second clip B212 can abut; alternatively, a gap can be formed between the first clip B211 and the second clip B212, the gap being smaller than the thickness of the electrode plate B110, thereby facilitating simultaneous contact between the electrode plate B110 and the first clip B211 and the second clip B212.

[0139] In this embodiment, two electrode pieces B110 correspond one-to-one with two charging pieces B210. The electrode piece B110 can be inserted between the corresponding first clip B211 and second clip B212 along the third direction Z, and the two surfaces of the electrode piece B110 along the third direction Z respectively abut against the first clip B211 and the second clip B212 for charging.

[0140] In this embodiment, the charging plate B210 is configured as a first clip B211 and a second clip B212 facing each other along the third direction Z. During charging, the electrode plate B110 is inserted between the first clip B211 and the second clip B212, and the two surfaces of the electrode plate B110 are in contact with the first clip B211 and the second clip B212 respectively, thereby increasing the contact area, which is beneficial to improving the charging speed and enhancing the user experience.

[0141] The specific structures of the first charging unit B100 and the second charging unit B200 in this embodiment have been described in detail above. The specific structures of the first charging unit B100 and the second charging unit B200 in the following embodiments are also described above.

[0142] Referring to Figures 20 to 25, this embodiment also provides a charging system, including a first device B10, a second device B20, and the aforementioned charging components. The first charging unit B100 is mounted on the first device B10, and the second charging unit B200 is mounted on the second device B20. The first device B10 can be, for example, a charging station, and the second device B20 can be, for example, a lawnmower.

[0143] The charging system in this embodiment uses the above-mentioned charging components, which increases the contact area between the first device B10 and the second device B20 during charging, thereby improving the charging speed of the second device B20.

[0144] Please continue referring to Figures 20 and 23. In this embodiment, the first device B10 has an opening, and the first charging part B100 passes through the opening, making the first charging part B100 exposed outside the first device B10, thereby facilitating the charging of the second device B20. The second device B20 has a fixing groove B21, and the second charging part B200 is disposed in the fixing groove B21; for example, the second housing B220 can be fixed to the fixing groove B21 by fasteners such as screws.

[0145] As shown in Figure 23, in a plane perpendicular to the first direction X, the cross-sectional area of ​​the fixing groove B21 gradually increases in the direction away from the second device B20; that is, the opening of the fixing groove B21 is funnel-shaped, the opening area is gradually changing, and the area of ​​the opening end of the fixing groove B21 is the largest.

[0146] Correspondingly, in this embodiment, the electrode sheet B110 is provided with a guide section 112 at the end away from the first device B10. In a plane perpendicular to the first direction X, the cross-sectional area of ​​the guide section 112 gradually decreases in the direction away from the first device B10.

[0147] With the above structure, when the first charging unit B100 is inserted into the fixing groove B21 along the third direction Z, the guide section 112 on the electrode plate B110 cooperates with the side wall of the fixing groove B21, thereby guiding the electrode plate B110 on the first charging unit B100 to cooperate smoothly with the charging plate B210 so that charging can proceed smoothly.

[0148] In some embodiments, the fixing groove B21 of this embodiment includes two sidewalls opposite each other along the second direction Y, and a clearance groove B22 is provided on the sidewalls. The size of the clearance groove B22 in the third direction Z is adapted to the size of the first charging part B100 in the third direction Z, thereby further reducing the interference phenomenon when the first charging part B100 enters the fixing groove B21.

[0149] In this embodiment, the first charging unit B100 is rotatably mounted on the first device B10. When the first charging unit B100 is subjected to an external force, it can rotate relative to the first device B10 within a certain angle range, thereby reducing the possibility of the first charging unit B100 being damaged by the external force.

[0150] As shown in Figures 24 and 25, specifically, the first charging unit B100 of this embodiment further includes two rotating shafts B130, which are located on both sides of the first charging unit B100 along the second direction Y. The first device B10 is provided with two spaced-apart rotating shaft grooves B11, and the two rotating shafts B130 are respectively disposed in the two rotating shaft grooves B11.

[0151] In some embodiments, the cross-section of the shaft groove B11 can be semi-circular. The first device B10 also includes two fixing members B13. Each fixing member B13 has a semi-circular groove B131, whose cross-section is also semi-circular and matches the shaft groove B11. The fixing members B13 can be used to fix the shaft B130 to the housing of the first device B10. The fixing members B13 may also have through holes at both ends. The housing of the first device B10 has corresponding fixing holes. The second fastener B14 passes through the through holes and is fixed in the corresponding fixing holes, thereby fixing the fixing member B13 to the housing of the first device B10 and securing the shaft B130 between the fixing member B13 and the shaft groove B11.

[0152] In some embodiments, the first device B10 of this embodiment is further provided with a torsion spring B12, which is sleeved on the rotating shaft B130, and both ends of the torsion spring B12 are fixedly connected to the first device B10. By providing the torsion spring B12, the first charging unit B100 can be rotated relative to the first device B10 and then return to its initial state under the action of the torsion spring B12, so as to facilitate subsequent charging.

[0153] For example, the first device B10 in this embodiment may further include a clearance member B15, which is disposed adjacent to the first charging unit B100. A clearance space is formed on the portion of the clearance member B15 exposed outside the housing of the first device B10, allowing the first charging unit B100 to be positioned within this clearance space when rotating relative to the first device B10. The clearance member B15 may be provided with a torsion spring fixing groove B151, where one end of a torsion spring B12 can be fixed, and the other end of the torsion spring B12 can be fixed to the housing of the first device B10.

[0154] Drive wheels are important components in mobile devices such as cars and lawnmowers. A drive wheel consists of a rim, a tire, and a hub motor. The tire is fitted around the outer circumference of the rim, and the hub motor is integrated with the rim.

[0155] In related technologies, since the rim and hub motor, which house the tires, are integrated into one unit, when mobile equipment needs to replace drive wheels of different specifications, that is, when changing the outer diameter of the drive wheel, or when one of the rim and hub motor is damaged and needs to be replaced, the entire integrated rim and hub motor must be replaced, resulting in poor replacement flexibility.

[0156] Therefore, referring to Figures 26 and 27, this disclosure provides a rim C1 for a self-moving robot, including a central disk C11, an outer wheel assembly C12, and a connecting structure C13. The outer wheel assembly C12 is coaxially connected to the outer periphery of the central disk C11 and is connected to a tire C2. The connecting structure C13 is detachably connected to an external drive component C3, and is disposed on the central disk C11.

[0157] In this embodiment, the radial dimensions of the center disc C11 of different rims C1 are equal, while the radial dimensions of the outer wheel assembly C12 of different rims C1 can be designed to be different according to different specifications in actual applications, so that the radial dimensions of the outer wheel assembly C12 of different rims C1 are different. In this embodiment, the axial dimensions of the center disc C11 and the axial dimensions of the outer wheel assembly C12 of the same rim C1 can be equal or unequal; the axial dimensions of the center disc C11 of different rims C1 can be equal or unequal, and the axial dimensions of the outer wheel assembly C12 of different rims C1 can be equal or unequal. The specific design can be set according to actual needs, and this embodiment does not impose specific limitations on this. In this embodiment, the outer wheel assembly C12 and the center disc C11 can be connected by a fixed connection (e.g., welding, screwing, etc.), or the outer wheel assembly C12 and the center disc C11 can be integrally formed, which can be set according to actual conditions. In this embodiment of the present disclosure, a mating structure C31 adapted to the connecting structure C13 is provided at a corresponding position on the external driving component C3. The connecting structure C13 and the mating structure C31 are detachably connected so that the rim C1 can be detachably connected to the external driving component C3.

[0158] In this embodiment, the connecting structure C13 of the rim C1 is detachably connected to the external drive component C3. The connecting structure C13 is located on the central disk C11. Since the radial dimensions of the central disks C11 of different rims C1 are the same, different rims C1 corresponding to central disks C11 with the same radial dimensions can be detachably connected to the same drive component C3. This allows the same drive component C3 to be adapted to install different rims C1, increasing the flexibility of replacing rims C1. Compared to related technologies that require replacing the entire rim C1 and hub motor, in this embodiment, because the connecting structure C13, which detachably connects to the drive component C3, is located on the central disk C11 of the rim C1, different rims C1 can be detachably connected to the same drive component C3. When it is necessary to change the specifications of the rim C1 or when the rim C1 is damaged, only the rim C1 needs to be disassembled and replaced. Therefore, the rim C1 in this disclosure has the advantage of high replacement flexibility.

[0159] Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the connecting structure C13 is detachably connected to the driving member C3 from the center disk C11 toward the driving member C3, and the rim C1 is detachably connected to the driving member C3.

[0160] In this embodiment, the direction from the central disk C11 toward the driving component C3 is the mounting direction D in Figure 27. Since the rim C1 is located on the outside of the self-moving robot compared to the driving component C3, the mounting direction D is the direction from the outside of the self-moving robot toward the inside. Therefore, the connecting structure C13 is detachably connected to the driving component C3 from the mounting direction D, i.e., from the outside to the inside, which facilitates the disassembly and installation of the connecting structure C13 and the driving component C3, and thus facilitates the removal and replacement of the rim C1.

[0161] Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the connecting structure C13 is disposed on the outer periphery of the central disk C11.

[0162] In this embodiment, the connecting structure C13 is disposed on the outer periphery of the center disk C11, and the mating structure C31 on the driving component C3 is disposed on the driving component C3 at a position corresponding to the connecting structure C13. In the wheel rim C1 provided in this embodiment, the connecting structure C13 is disposed on the outer periphery of the center disk C11, which can reduce the impact of the connecting structure C13 on the strength of the center disk C11, and also facilitates the embedding of the center disk C11 of the wheel rim C1 into the driving component C3, making the installation between the wheel rim C1 and the driving component C3 more compact, thereby saving installation space.

[0163] In some other embodiments, the connecting structure C13 may also be located in the middle of the central disk C11.

[0164] Referring to Figures 26 and 27, in some possible embodiments of this disclosure, a protrusion C111 is provided on the outer periphery of the central disk C11, and a connecting structure C13 is disposed on the protrusion C111. In this embodiment, the protrusion C111 may protrude radially along the rim C1 on the outer periphery of the central disk C11. Furthermore, the shape of the radial cross-section of the protrusion C111 along the rim C1 may be semi-circular, rectangular, triangular, etc. In this embodiment, the protrusion C111 may be a flange structure protruding radially along the rim C1, or it may be a protrusion structure protruding relative to the outer periphery of the central disk C11, which can be specifically set according to actual needs. In this embodiment, a corresponding protrusion structure may also be provided on the outer periphery of the external drive component C3, so that the mating structure C31 is disposed on the protrusion structure. In the wheel rim C1 provided in this embodiment, the connecting structure C13 is disposed on the protrusion C111 on the outer periphery of the central disk C11, making it difficult for the connecting structure C13 to affect the structure of the central disk C11, thus greatly reducing the impact of the connecting structure C13 on the structure of the central disk C11.

[0165] Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the connecting structure C13 includes a connecting hole C131 formed in the central disk C11. In this embodiment, the connecting structure C13 further includes a connecting rod adapted to the connecting hole C131, and the mating structure C31 on the external drive member C3 is configured as a mating hole C112 adapted to the connecting rod. For example, the connecting rod is configured as a bolt, the mating hole C112 is configured as a threaded hole, and the bolt passes through the connecting hole C131 and is screwed into the threaded hole, so that the rim C1 is screwed to the drive member C3. In this embodiment, when the connecting structure C13 includes the connecting hole C131, it facilitates the machining and manufacturing of the connecting structure C13 on the central disk C11.

[0166] Referring to FIG28, in some other possible embodiments of this disclosure, the connecting structure C13 includes a connecting post C132 formed on the central disk C11. In embodiments of this disclosure, when the connecting structure C13 includes a connecting post C132 formed on the central disk C11, the mating structure C31 on the external drive member C3 is configured as a mating hole C112 adapted to the connecting post C132. For example, when the outer periphery of the connecting post C132 is provided with external threads, the inner periphery of the mating hole C112 is provided with internal threads, and the connecting post C132 with external threads is screwed into the mating hole C112 with internal threads, so that the rim C1 is screwed onto the drive member C3.

[0167] In this embodiment, the connecting post C132 and the central disk C11 can be connected by a fixed connection (e.g., welding, screwing, etc.), or the connecting post C132 and the central disk C11 can be integrally formed, depending on the actual situation. In this embodiment, when the connecting structure C13 includes the connecting post C132, it can enhance the strength of the central disk C11. Referring to FIG29, in some other possible embodiments of this disclosure, the connecting structure C13 includes a snap-fit ​​structure C133 formed on the central disk C11.

[0168] In this embodiment, the snap-fit ​​structure C133 can be a snap-fit, a slot, or other similar structure, and the mating structure C31 on the external drive component C3 is adapted to the snap-fit ​​structure C133. In this embodiment, when the connecting structure C13 includes the snap-fit ​​structure C133, it facilitates the connection between the central disk C11 and the drive component C3.

[0169] The wheel rim C1 provided in this embodiment can have a connecting structure C13 designed according to its actual structure and connection requirements. This connecting structure C13 includes one or more of a connecting hole C131, a connecting post C132, and a snap-fit ​​structure C133, thereby increasing the design flexibility of the connecting structure C13. Referring to Figures 26 and 27, in some possible embodiments of this disclosure, there are at least two connecting structures C13, which are evenly distributed around the central axis of the central disk C11. In this embodiment, the number of connecting structures C13 can be two, three, five, etc., and multiple connecting structures C13 are evenly distributed around the central axis of the central disk C11. The wheel rim C1 provided in this embodiment, with at least two connecting structures C13 evenly distributed around the central axis of the central disk C11, results in a more uniform force distribution between the central disk C11 and the driving component C3, thereby improving the stability of the connection between the central disk C11 and the driving component C3.

[0170] Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the central disk C11 has a coaxially arranged mating hole C112, which is engaged with the driving member C3. In this embodiment, the driving member C3 may have a third flange C32 extending axially along the side of the central disk C11. The radial dimension of the third flange C32 is adapted to the radial dimension of the mating hole C112, so that the third flange C32 of the driving member C3 is engaged in the mating hole C112 to achieve axial positioning. The rim C1 provided in this embodiment of the disclosure, with the mating hole C112, facilitates the installation between the central disk C11 and the driving member C3, and also facilitates the coaxial arrangement of the central disk C11 and the driving member C3. Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the central disk C11 also includes a first flange C113 extending axially, which forms part of the inner wall of the mating hole C112.

[0171] In this embodiment, a first flange C113 can be provided on the side of the center disc C11 away from the drive member C3, or on the side of the center disc C11 closer to the drive member C3, or on both sides of the center disc C11 away from and close to the drive member C3. The specific configuration can be determined according to actual needs. The first flange C113 of the wheel rim C1 provided in this embodiment can strengthen the center disc C11, thereby improving the strength of the wheel rim C1. Referring to Figures 26 and 27, in some possible embodiments of this disclosure, the outer wheel assembly C12 includes a wheel rim C121 and a support member C122. There are at least two support members C122, and at least two support members C122 are connected between the wheel rim C121 and the center disc C11. In this embodiment, the support member C122 connects the wheel rim C121 and the center disc C11, and provides support between the wheel rim C121 and the center disc C11. Furthermore, the support components C122 can be arranged at an angle to provide better support between the wheel rim C121 and the center disc C11.

[0172] In this embodiment of the disclosure, there are gaps between the support members C122 to reduce the weight of the rim C1.

[0173] In this embodiment of the disclosure, the support member C122 and the wheel rim C121, as well as the support member C122 and the center disk C11, can be connected by a fixed connection (e.g., welding, screwing, etc.); the wheel rim C1, which includes the wheel rim C121, the support member C122 and the center disk C11, can also be integrally formed, and its specific configuration can be set according to the actual situation.

[0174] In this embodiment, the number of support members C122 can be two, eight, sixteen, etc., and can be set according to actual needs.

[0175] In this embodiment, the outer periphery of the rim C121 may be provided with guide portions C125 that protrude radially along the rim C121. The number of guide portions C125 can be one or more. When multiple guide portions C125 are provided, they are evenly spaced on the outer periphery of the rim C121. When the tire C2 is fitted onto the rim C121, the guide portions C125 increase the friction between the tire C2 and the rim C121, thereby limiting the rotation of the tire C2 relative to the rim C121 axially. Furthermore, the positions of the tire C2 corresponding to the guide portions C125 can also be provided with recesses, and the guide portions C125 engage with these recesses to improve the limiting ability of the guide portions C125 to restrict the axial rotation of the tire C2 relative to the rim C121.

[0176] Furthermore, when the tire C2 is detachably separated from the rim C121, the guide portion C125 can extend axially along the rim C121 to guide the tire C2 as it moves axially along the rim C121. Moreover, along the axial direction of the rim C121, the guide portion C125 gradually increases in size from the end near the obstruction member C14 to the end away from the obstruction member C14, so that the guide portion C125 can axially limit the tire C2 at least at the end away from the obstruction member C14.

[0177] The wheel rim C1 provided in this embodiment has a wheel hub C121 fitted onto a tire C2, and a support member C122 connecting the wheel hub C121 and the center disc C11, providing support between the wheel hub C121 and the center disc C11. Compared to a solid outer wheel assembly C12, the outer wheel assembly C12 including the wheel hub C121 and the support member C122 in this embodiment can improve the lightweighting of the wheel rim C1.

[0178] Referring to Figures 27 and 30, in some possible embodiments of this disclosure, the rim C1 further includes a shielding member C14, which is detachably connected to the outer wheel assembly C12 to at least cover the center disc C11.

[0179] In this embodiment of the disclosure, the shielding member C14 is configured as a disc-shaped structure to at least cover the central disc C11.

[0180] In this embodiment of the present disclosure, the shielding member C14 can be connected to the outer wheel assembly C12 by means of snap-fit, screw-fit, or other methods. Taking the shielding member C14 snap-fitted to the outer wheel assembly C12 as an example, referring to FIG30, the shielding member C14 is provided with a snap-fit ​​part C141 on the side near the outer wheel assembly C12, and a mating part C124 is provided at a corresponding position on the wheel rim C121 of the outer wheel assembly C12. The snap-fit ​​part C141 snaps onto the mating part C124, so that the shielding member C14 is snapped onto the wheel rim C121 of the outer wheel assembly C12.

[0181] In this embodiment of the present disclosure, the shielding member C14 may be provided with at least two snap-fit ​​portions C141, which are evenly arranged around its axis on the shielding member C14. The corresponding position on the wheel rim C121 of the outer wheel assembly C12 is provided with a corresponding number of mating portions C124, so that the force between the shielding member C14 and the wheel rim C121 of the outer wheel assembly C12 is more uniform.

[0182] In this embodiment of the present disclosure, the side of the shielding member C14 away from the outer wheel assembly C12 may be provided with patterns, designs, or other decorative textures to enable the shielding member C14 to serve a decorative function on the wheel rim C1.

[0183] The wheel rim C1 provided in this embodiment has a shielding component C14 that can shield the outer side of the wheel rim C1 to reduce the splashing of sand, mud, water, etc. into the interior of the wheel rim C1, thereby protecting the wheel rim C1; the shielding component C14 can also decorate the outer side of the wheel rim C1 to improve the aesthetics of the wheel rim C1.

[0184] Referring to Figures 27 and 30, in some possible embodiments of this disclosure, the outer wheel assembly C12 is provided with a second flange C123 extending axially on the side away from the shielding member C14. The outer diameter of the second flange C123 is smaller than the outer diameter of the outer wheel assembly C12, so as to form a limiting space at the second flange C123. The limiting space can axially limit the tire C2.

[0185] In this embodiment of the present disclosure, the outer wheel assembly C12 forms a stepped portion at the second flange C123. When the tire C2 is fitted onto the outer wheel assembly C12, the axial side of the tire C2 is stuck at the stepped portion. Therefore, when the tire C2 is subjected to an axial outward force, the stepped portion can play an axial limiting role for the tire C2.

[0186] In this embodiment, the second flange C123 can be provided on the side of the outer wheel assembly C12 away from the shielding member C14, or the second flange C123 can be provided on both sides of the outer wheel assembly C12 along the axial direction. Furthermore, when the second flange C123 is provided on both sides of the outer wheel assembly C12 along the axial direction, the second flange C123 on the side of the outer wheel assembly C12 away from the shielding member C14 provides an outward limiting force, and the second flange C123 on the side of the outer wheel assembly C12 closer to the shielding member C14 provides an inward limiting force.

[0187] The rim C1 provided in this embodiment has a second flange C123 that forms a limiting space at the second flange C123 for the outer wheel assembly C12. When the tire C2 is fitted onto the outer wheel assembly C12, the tire C2 can be axially limited at the second flange C123, thereby improving the stability of the connection between the rim C1 and the tire C2.

[0188] Referring to Figures 27, 31 and 32, this disclosure also provides a drive wheel for a self-moving robot, including a rim C1 and a tire C2 as described above, wherein the tire C2 is connected to the outer periphery of the outer wheel assembly C12.

[0189] In this embodiment, the tire C2 and the rim C1 can be manufactured separately, meaning the tire C2 and the rim C1 are detachable. In this case, the inner diameter of the tire C2 needs to be smaller than the outer diameter of the outer wheel assembly C12 so that the tire C2 can be fixed on the outer wheel assembly C12. Since the tire C2 is made of rubber, meaning the tire C2 has deformation capability, when the tire C2 is fitted onto the outer circumference of the outer wheel assembly C12 and moved axially along the outer wheel assembly C12, the inner circumferential side of the tire C2 undergoes radial outward deformation. When the inner circumferential side of the tire C2 moves to the second flange C123 of the rim C1, since the outer diameter of the second flange C123 is smaller than the outer diameter of the outer wheel assembly C12, the inner circumferential side of the tire C2 will rebound radially inward and embed into the limiting space formed at the second flange C123 to achieve axial limiting, thereby completing the installation process. Tire C2 and rim C1 can also be manufactured as a single piece. For example, the tire C2 mold can be fixed on the outer periphery of the outer wheel assembly C12, and the tire C2 and rim C1 can be integrally formed by injection molding.

[0190] Referring to Figures 27, 33, 34, and 35, embodiments of this disclosure also provide a drive mechanism for a self-moving robot, including a rim C1 of any of the aforementioned self-moving robots; or, a drive wheel of the aforementioned self-moving robot. The drive mechanism for the self-moving robot further includes a drive member C3, which is detachably connected to a connection structure C13 of the rim C1.

[0191] This disclosure also provides a lawn mowing device, including a device body and a drive mechanism for the aforementioned self-moving robot. The drive mechanism is connected to the device body to drive the device body to move.

[0192] The drive wheel, drive mechanism, and lawn mowing device of the self-moving robot provided in this disclosure all include the rim C1 of this disclosure, thus achieving the same effect: the radial dimensions of the central disk C11 of different rims C1 are all the same, and the connection structure C13 for detachably connecting the drive component C3 is set on the central disk C11 of the rim C1, so that different rims C1 can be detachably connected to the same drive component C3 respectively. When it is necessary to change the specifications of the rim C1 or when the rim C1 is damaged, it is only necessary to disassemble and replace the rim C1. Therefore, the rim C1 of this disclosure has the advantage of high replacement flexibility.
