[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] Embodiment 1

[0037] The embodiment of the utility model provides a magnetic adhering device which enables a first object 1 to be detachably connected to a second object 2 .

[0038] Please refer to Figure 1-3 The magnetic adhering device includes a magnetic member 3, and the whole or part of the magnetic member 3 is a magnet 32.

[0039] The first surface of the magnetic member 3 is bonded with a magnetic double-sided adhesive tape 51, and the side of the magnetic double-sided adhesive tape 51 facing away from the magnetic member 3 is used to bond the first object 1. The second surface of the magnetic member 3 is provided with a limiting groove 311, and the first surface and the second surface of the magnetic member 3 are opposite surfaces. Figure 2 The upward side of the magnetic attraction member 3 shown in the figure is its first side, and the downward side is its second side.

[0040] The magnetic adhesion device also includes a limiting member 4 for being embedded in the limiting groove 311 and abutting against the limiting groove 311 for limiting position. A limiting double-sided adhesive tape 61 is bonded to the side of the limiting member 4 facing away from the limiting groove 311. The side of the limiting double-sided adhesive tape 61 facing away from the limiting member 4 is used to bond the second object 2. The second object 2 is magnetically connected to the magnet 32, that is, the second object 2 can be magnetically connected to the magnetic member 3 through the magnet 32.

[0041] Among them, the first object 1 and the second object 2 can be different objects according to the needs of different embodiments. The material of the first object 1 is not limited in terms of magnetism, and can be metal, plastic, glass, etc. The first object 1 has a surface suitable for bonding the magnetic double-sided tape 51. The second object 2 needs to be magnetically connected to the magnetic attraction part 3 through the magnet 32, so the second object 2 has a surface suitable for bonding the limiting double-sided tape 61 and the surface has the ability to be magnetically connected by the magnet 32, that is, the surface should include ferromagnetic metal or other magnets with opposite magnetic poles to the magnet 32 ​​in the magnetic attraction part 3.

[0042] The magnetic double-sided adhesive tape 51 is provided on the magnetic member 3 so that the magnetic member 3 can be fixed on the first object 1, and the magnetic member 3 and the second object 2 can be connected by magnetic attraction. Therefore, the first object 1 can be connected to the second object 2 by magnetic attraction through the magnetic member 3, so that the first object 1 and the second object 2 can be detachably connected. In addition, the present embodiment is provided with a limit groove 311 and a limit member 4, and the limit member 4 abuts against the limit groove 311 to limit the freedom of the magnetic member 3 in the front, back, left and right directions. In this way, through the cooperation of the limit groove 311 and the limit member 4, the problem of relative sliding and displacement of the two objects connected by magnetic attraction can be avoided. Specifically, the limit groove 311 is a rectangular groove, and the limit member 4 is a rectangular sheet. Therefore, when the limit member 4 is fixed, the limit groove 311 abuts against the limit member 4, so that relative sliding and rotation cannot occur between the first object 1 and the second object 2.

[0043] In this embodiment, the side of the magnetic double-sided adhesive tape 51 facing away from the magnetic member 3 is bonded with a magnetic isolation paper 52, and the side of the position-limiting double-sided adhesive tape 61 facing away from the position-limiting member 4 is bonded with a position-limiting isolation paper 62. The provision of isolation paper can protect the stickiness of the double-sided adhesive tape, and also make the magnetic adhesive device non-sticky when not in use to facilitate transportation and storage. When using the magnetic adhesive device, the magnetic isolation paper 52 is uncovered and the magnetic member 3 is bonded to the first object 1, and the position-limiting isolation paper 62 is uncovered and the position-limiting member 4 is bonded to the second object 2.

[0044] In this embodiment, the limiting groove 311 is located at the center of the magnetic attraction member 3, so that the magnetic attraction member 3 is more beautiful and has a better limiting effect.

[0045] Please refer to Figure 2-3In this embodiment, the part of the magnetic attraction member 3 is a magnet 32. Specifically, the magnetic attraction member 3 includes a magnet mounting frame 31, and the magnet mounting frame 31 is provided with a plurality of magnet mounting holes 312 for accommodating the magnet 32. The magnet 32 ​​is fixedly embedded in the magnet mounting holes 312. In this embodiment, the number of the magnet mounting holes 312 is 6, and they are arranged in a 3*2 rectangular array.

[0046] The magnetic double-sided adhesive tape 51 is adhered to the first surface of the magnet mounting frame 31 , and the limiting groove 311 is provided on the second surface of the magnet mounting frame 31 . The first surface and the second surface of the magnet mounting frame 31 are opposite surfaces. Figure 2 The upward side of the magnet mounting frame 31 shown in FIG. 1 is its first side, and the downward side is its second side. Figure 3 The structure of the second side of the magnet mounting frame 31 is shown.

[0047] The arrangement of several magnet mounting holes 312 can provide several adsorption sites for the magnet 32. Multiple adsorption sites can provide strong magnetic attraction, making the magnetic connection between the magnetic attraction part 3 and the second object 2 more stable. The magnet mounting frame 31 has no requirements on magnetism, and can use a cheaper material than the magnet 32, thereby reducing the cost of the magnetic attraction part 3.

[0048] Please refer to Figure 3 The magnet mounting hole 312 passes through the second surface of the magnet mounting frame 31, that is, the magnet 32 ​​can be placed in the magnet mounting hole 312 through the second surface of the magnet mounting frame 31. The magnet 32 ​​needs to be fixed in the magnet mounting hole 312, and there are many ways to fix it.

[0049] In an optional embodiment, a double-sided adhesive may be provided on the contact surface between the magnet mounting hole 312 and the magnet 32 ​​to fix the magnet 32 ​​in the magnet mounting hole 312. The double-sided adhesive may be provided on the magnet mounting hole 312 and / or the magnet 32 ​​before installation, or may be squeezed into the gap between the magnet mounting hole 312 and the magnet 32 ​​after the magnet 32 ​​is embedded in the magnet mounting hole 312. The magnet mounting hole 312 may be a through hole or a blind hole. When the magnet mounting hole 312 is a through hole, the double-sided adhesive may be provided on the side wall of the magnet mounting hole 312 and / or the magnet 32; when the magnet mounting hole 312 is a blind hole, the double-sided adhesive may be provided on the aforementioned side wall, or may be provided on the bottom of the magnet mounting hole 312 and / or on the side of the magnet 32 ​​facing the bottom of the magnet mounting hole 312. In addition to the double-sided adhesive, the magnet mounting hole 312 and the magnet 32 ​​may also be fixed by interference connection.

[0050] Please refer to Figure 2-4 In this embodiment, a magnet decoration sticker 53 is bonded to the second surface of the magnet mounting frame 31 , and the magnet decoration sticker 53 covers the magnet mounting hole 312 , but does not cover the limiting groove 311 .

[0051] The magnet decoration sticker 53 and the magnet mounting frame 31 may be bonded by providing a double-sided adhesive on the second side of the magnet mounting frame 31 and / or on the side of the magnet decoration sticker 53 facing the magnet mounting frame 31. The magnet decoration sticker 53 can seal the magnet 32 ​​in the magnet mounting hole 312, thereby protecting the magnet 32 ​​from falling off and making the magnet 32 ​​concealed, thereby making the surface of the magnetic attraction member 3 more beautiful.

[0052] In this embodiment, the side of the magnet decorative sticker 53 facing the magnet mounting frame 31 is sticky, and the side of the magnet 32 ​​facing the magnet decorative sticker 53 is adhered to the magnet decorative sticker 53. The magnet decorative sticker 53 is made sticky so that it can not only adhere to the magnet mounting frame 31, but also adhere to the magnet 32, so that the magnet 32 ​​is more firmly fixed. The magnet decorative sticker 53 is sticky, and double-sided adhesive can be pre-adhered to the magnet decorative sticker 53 in advance, or a finished single-sided adhesive sticker can be directly used as the magnet decorative sticker 53. It is more convenient to use a finished single-sided adhesive sticker as the magnet decorative sticker 53.

[0053] In this embodiment, a plurality of avoidance holes 313 are further provided on the second surface of the magnet mounting frame 31, and the magnet decorative sticker 53 does not cover the avoidance holes 313. The avoidance holes 313 are blind holes, which are provided to avoid the raised structures such as bolt heads on the surface of the second object 2 adhesive limiter 4. Specifically, a decorative sticker through groove 531 having the same shape and size as the limiter groove 311 is provided at the position corresponding to the limiter groove 311 on the magnet decorative sticker 53, and a decorative sticker through hole 532 having the same shape and size as the avoidance hole 313 is provided at the position corresponding to the avoidance hole 313 on the magnet decorative sticker 53. The size and shape of the magnet decorative sticker 53 are the same as those of the magnet mounting frame 31, making the magnetic adhering device more beautiful as a whole.

[0054] Please refer to Figure 2 In this embodiment, the magnet mounting hole 312 passes through the first side of the magnet mounting frame 31, and the magnet 32 ​​is bonded to the magnetic double-sided adhesive tape 51 on one side facing the magnetic double-sided adhesive tape 51. That is, the magnet 32 ​​in this embodiment is arranged between the magnetic double-sided adhesive tape 51 and the magnet decorative sticker 53. Such an arrangement can not only make the magnet mounting frame 31 and the magnet 32 ​​firmly fixed, but also make the thickness of the magnet mounting frame 31 thinner. If the magnet mounting hole 312 is not a through hole, the thickness of the magnet mounting frame 31 must be greater than the thickness of the magnet 32. In this embodiment, the magnet mounting hole 312 is a through hole, which makes the magnetic attraction part 3 thin and beautiful, and also saves the material cost of the magnet mounting frame 31.

[0055] Please refer to Figure 5, the magnet 32 ​​in the magnetic attraction part 3 is a single-sided magnet. A single-sided magnet refers to a magnet with magnetism on one side and weak magnetism on the other side, that is, the single-sided magnet includes a strong magnetic surface 321 and a weak magnetic surface 322. The preparation method is to wrap one side of the double-sided magnet with a specially treated galvanized iron sheet, the magnetism of the wrapped side will be shielded, and the magnetic force will be refracted to the other side, and the magnetism of the other side will be enhanced. The side of the single-sided magnet facing the magnetic double-sided tape 51 is its weak magnetic surface 322. Therefore, due to the characteristics of the single-sided magnet, the first object 1 can be almost unaffected by magnetism. In this embodiment, the first object 1 is a battery, and the second object 2 is a battery base. The setting of the single-sided magnet can not only avoid the influence of the magnet 32 ​​on the battery, but also use the magnetic attraction ability of the magnet 32 ​​to achieve a detachable connection between the battery and the battery base.

[0056] This embodiment also provides a robot, which includes a battery and a battery base, and also includes the aforementioned magnetic adhering device, wherein the battery is a first object 1, the battery base is a second object 2, and the battery and the battery base are detachably connected via the magnetic adhering device.

[0057] The magnetic adhering device provided in this embodiment has the following advantages:

[0058] 1. The first object 1 and the second object 2 are detachably connected by magnetic connection. Compared with fixing methods such as cable ties and bolts, magnetic connection is more convenient;

[0059] 2. No installation holes need to be reserved on the first object 1 and the second object 2. The bonding position of the magnetic double-sided tape 51 on the first object 1 and the bonding position of the limiting double-sided tape 61 on the second object 2 can be adjusted according to user needs;

[0060] 3. The problem of easy displacement between the first object 1 and the second object 2 is avoided by the cooperation between the limiting member 4 and the limiting groove 311;

[0061] 4. The arrangement of the plurality of magnets 32 makes the magnetic connection between the first object 1 and the second object 2 more secure;

[0062] 5. The setting of the single-sided magnet prevents the first object 1 from being affected by the magnetism of the magnet 32;

[0063] 6. The provision of the magnetic decorative sticker 53 makes the magnet 32 ​​more firmly fixed and the overall magnetic adhering device more beautiful.

[0064] Embodiment 2

[0065] The difference between this embodiment and the first embodiment is that the entire magnetic attraction member 3 is a magnet 32 ​​, and the magnetic decorative sticker 53 is not provided in this embodiment.

[0066] Please refer to Figure 6In this embodiment, the entirety of the magnetic component 3 is a magnet 32, the first side of the magnet 32 ​​is bonded with a magnetic double-sided adhesive tape 51, and the second side is provided with a limiting groove 311, and the first side and the second side of the magnet 32 ​​are opposite sides. The second side of the magnet 32 ​​can also be provided with a plurality of avoidance holes 313 as required to avoid the raised structures such as bolt heads on the surface of the second object 2 adhesive limiting component 4, and the avoidance holes 313 are blind holes. The size and shape of the magnetic double-sided adhesive tape 51 are preferably the same as the size and shape of the first side of the magnet 32, so as to make the magnetic component 3 more beautiful as a whole.

[0067] The "several" mentioned in this article refers to one or more, and "multiple" and "at least two" refer to two or more. "And / or" describes the association relationship of the associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
