Mounts for display screens, smart speakers, and intelligent robotic arms, for example, are becoming increasingly popular. Existing mounts are typically directly adhered to the mounting surface using adhesive. Removing the mount often requires using a knife or spatula to create a gap between the adhesive joints. This can easily damage the mount or scratch the mounting surface, causing significant inconvenience for users. [Summary of the invention]

[0003] In order to overcome the disadvantage of the existing base being inconvenient to assemble and disassemble, the present invention provides a base with a simple structure and convenient assembling and disassembling.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a base, which includes a fixed part, a bottom and an outer shell, an inner sleeve is provided on the bottom, the fixed part is sleeved in the inner sleeve, the outer shell is sleeved on the outer surface of the fixed part and is detachably connected to the inner sleeve, and an adhesive sheet is also provided on the side of the bottom away from the fixed part.

[0005] Preferably, a through hole is opened at the bottom, and a connection area is formed in the area outside the through hole. A part of the adhesive sheet is connected to the connection area, and the other part extends into the through hole. After the adhesive sheet extending into the through hole covers part of the through hole, there is still a hollow area.

[0006] Preferably, the adhesive sheet is in a spiral structure, which includes two free ends, one of which is rolled up relative to the other end to form the spiral structure, at least one end located on the inner side of the spiral structure is located in the through hole, and the adhesive sheet has at least one circle of spiral line connected to the connection area.

[0007] Preferably, one end located on the outside of the spiral linear structure is a pointed structure, and the line width of the pointed structure gradually increases from one end to the other end to form a round-headed structure with a length dimension, and the pointed structure and a partial area of the free end located on the inside are connected to the connection area.

[0008] Preferably, the bottom further includes a disc-shaped bottom plate, the inner sleeve is cylindrical and connected to the bottom plate, the through hole is provided on the bottom plate and communicates with the inner sleeve, the fixing portion is sleeved in the inner sleeve and one end contacts the bottom plate.

[0009] Preferably, the fixing portion includes at least one sub-fixing portion, each of the sub-fixing portions includes a connecting portion, and the connecting portion is provided with a latching position for connecting with the robot arm. When there are two or more sub-fixing portions, the circumferential dimension formed by the splicing and enclosing of each sub-fixing portion corresponds to the inner diameter dimension of the inner sleeve.

[0010] Preferably, the side of the fixing portion facing the bottom is a hollow structure.

[0011] Preferably, reinforcing ribs are provided inside the fixing portion of the hollow structure.

[0012] Preferably, the connection between the outer shell and the inner sleeve includes any one of a threaded connection, a snap-fit connection or a magnetic connection.

[0013] Preferably, a first helical tooth group is provided on the outer side of the inner sleeve, and a second helical tooth group is provided on the inner side of the outer shell. The first helical tooth group and the second helical tooth group can be rotatably engaged to connect the outer shell and the inner sleeve.

[0014] Compared with the prior art, the base provided by the present invention has the following advantages:

[0015] 1. The present invention provides a base comprising a fixed portion, a bottom, and an outer shell. The bottom is provided with an inner sleeve, the fixed portion is sleeved within the inner sleeve, and the outer shell is sleeved on the outer surface of the fixed portion and is detachably connected to the inner sleeve. An adhesive sheet is also provided on the side of the bottom away from the fixed portion. The outer shell presses against the fixed portion, further securing it, making the base a stable entity, simplifying the external structure, and achieving integration.

[0016] 2. The fixing part includes one or more sub-fixing parts, each of which is provided with a connecting part that can be connected to a robot arm; at the same time, the fixing part is a hollow structure with reinforcing ribs inside, so that it can reduce weight while maintaining sufficient rigidity.

[0017] 3. The present invention provides a base having a through-hole formed in the bottom portion, forming a connection area outside the through-hole. A portion of the adhesive sheet is connected to the connection area, while another portion extends into the through-hole. A hollow area exists between the adhesive sheet extending into the through-hole and the through-hole. The edge of the adhesive sheet is first peeled off at the hollow area, and the adhesive sheet is stretched to thin it at a critical point. The adhesive sheet can then be gradually torn off in the tearing direction with minimal effort. Therefore, the base can be removed without applying direct force to the bottom portion.

[0018] 4. The adhesive sheet is in a spiral shape. Compared with a straight line structure, the spiral structure can be gradually disassembled along the spiral direction to avoid the tangential force component parallel to the plane of the adhesive sheet offsetting the pulling force applied by the human hand, thereby further saving effort during disassembly.

[0019] 5. In the present invention, the structure of the adhesive sheet is further defined, wherein the pointed end located on the outside of the spiral linear structure is a pointed structure. Starting from the pointed end, the line width gradually increases from one end to the inner rounded end to form a rounded structure with a certain length. The pointed end and a portion of the inner rounded end are connected to the connecting area. By peeling off the inner rounded end, the outer pointed end is gradually reached. Since the line width gradually decreases, the adhesive force applied to the adhesive sheet during the peeling process also gradually decreases, thereby allowing the base to be removed quickly and effortlessly.

[0020] 6. A first helical tooth group is provided on the outer side of the inner sleeve, and a second helical tooth group is provided on the inner side of the outer shell. The first helical tooth group and the second helical tooth group can be rotatably engaged to connect the outer shell to the inner sleeve. When the fixing portion tends to drive the outer shell to move upward, the first helical tooth group and the second helical tooth group will produce a self-locking phenomenon due to their inclination, so that the inner sleeve and the outer shell remain firmly connected, and the fixing portion remains in a stable state.

[Specific implementation method]

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] See also Figure 1 The first embodiment of the present invention provides a base 100 comprising a bottom 120 and an adhesive sheet 110. The adhesive sheet 110 is bonded to the bottom 120, and the side of the bottom 120 facing away from the adhesive sheet 110 can be connected to an external device. The base 100 can be directly connected to the external device or indirectly connected to the external device by adding an intermediate connector. The external device may include, but is not limited to, robotic components, electronic devices with displays, smart speakers, cameras, and other devices that need to be mounted on a surface.

[0029] In this embodiment, in order to make the base 100 have better adhesion ability and not easily leave adhesion marks on the installation surface, the material of the adhesive sheet 110 may further include but is not limited to removable glue, thermoplastic elastomer, and silicone. It can be attached to a smoother surface using vacuum or static electricity and can be reused or replaced.

[0030] Please refer to Figure 2 In some preferred embodiments, to facilitate portability and removal of the adhesive sheet 110, a through hole 122 is formed on the bottom 120. The bottom 120 forms a connection area 123 outside the through hole 122. A portion of the adhesive sheet 110 is connected to the connection area 123, while another portion extends into the through hole 122. The adhesive sheet 110 only partially covers the through hole 122, so that after the adhesive sheet 110 is adhered to the bottom 120, a hollow area is formed.

[0031] When the base 100 is installed, the adhesive sheet 110 adheres to the surface to be installed. Due to the large contact area between the adhesive sheet 110 and the installation surface, the base 120 will not easily fall off when subjected to force after installation. When the base 100 needs to be removed, the edge of the adhesive sheet 110 is first peeled off through the through hole 122, and then the adhesive sheet 110 can be easily torn off along the extension direction of the adhesive sheet 110. When the adhesive sheet 110 is torn off, the base 120 is also removed. Therefore, the base 120 can be removed without directly applying force to the base 120, and the base 100 can be easily removed from the installation surface without leaving any marks.

[0032] See also Figure 2The adhesive sheet 110 has a spiral structure and includes two free ends 113, one of which is rolled up relative to the other end to form the spiral structure. At least one outer loop of the adhesive sheet 110 is connected to the bottom 120 to fully secure the bottom 120. One inner end of the spiral structure is located within the through hole 122. By designing the adhesive sheet 110 as a spiral structure, when the adhesive sheet 110 needs to be torn off, the adhesive sheet 110 can move the bottom 120 along its own spiral trajectory. Compared to a straight structure, the spiral structure can be gradually disassembled along the extension direction of the spiral structure, avoiding the tangential force component parallel to the plane of the adhesive sheet 110 offsetting the pulling force applied by the human hand, thereby achieving a further labor-saving effect during disassembly.

[0033] When the base 100 needs to be disassembled, the edge of the adhesive sheet 110 is first peeled off through the through hole 122, and the spiral structure of the adhesive sheet 110 is gradually torn apart radially, so that the adhesive sheet 110 is stretched and elongated. The thickness of the part of the adhesive sheet 110 close to the bonding plane becomes thinner due to the stretching, so that the adhesive sheet 110 can be easily separated from the mounting surface to which it is adhered. In this way, the base 100 can be removed without directly applying force to the bottom 120, achieving a quick disassembly effect.

[0034] In order to make the adhesive sheet 110 easy to remove while having good adhesion, the end located on the outside of the spiral linear structure can be further defined as a pointed end 112. The pointed end 112 has a pointed structure. Starting from the pointed end 112, the line width of the adhesive sheet 110 gradually increases from one end to the inner round end 111 to form a round structure with a length dimension. The pointed end 112 and a partial area of the inner round end 111 are connected to the connecting area 123. By peeling off the inner round end 111 and gradually reaching the outer pointed end 112, since its line width gradually decreases, the adhesion force gradually decreases during the process of tearing off the adhesive sheet 110, which further makes it easier to remove the base 100.

[0035] See also Figure 3 、 Figure 4In order to make the base 100 better fix the external device and have better adhesion, the second embodiment of the present invention further discloses a base 100, which is different from the base 100 in the above-mentioned first embodiment in that: the base 100 also includes a fixing part 130, wherein the bottom 120 may further include a circular bottom plate 121, and a cylindrical inner sleeve 124 with a certain height connected to the bottom plate 121, the adhesive sheet 110 is connected to the bottom plate 121, and the fixing part 130 is sleeved in the inner sleeve 124 and one end is in contact with the bottom plate 121.

[0036] The fixing portion 130 includes at least one sub-fixing portion 131, each of the sub-fixing portions 131 includes a connecting portion 132, and the connecting portion 132 is provided with a latching position for connecting with the robot arm. When there are two or more sub-fixing portions 131, the circumferential dimension formed by the splicing and enclosing of each sub-fixing portion 131 corresponds to the inner diameter dimension of the inner sleeve 124.

[0037] Specific as Figure 4 As shown in FIG, there are two sub-fixing portions 131, and portions of the two sub-fixing portions 131 extend into the inner sleeve 124 in an interference fit manner. This allows the fixing portion 130 to be fixed within the base 120, preventing unnecessary displacement of the fixing portion 130 when connected to other equipment.

[0038] See also Figure 4 A protrusion 134 is provided at one end of the sub-fixing portion 131 close to the bottom 120 . When in the installed state, the protrusion 134 presses the adhesive sheet 110 .

[0039] Thus, the rounded end 111 of the adhesive sheet 110 can be pressed tightly, so that the base 100 is more adhered to the mounting surface.

[0040] See also Figure 4 In another embodiment of the present invention, a hollow structure is provided on the side of the fixing portion 130 facing the bottom 120, and a plurality of reinforcing ribs 133 are provided inside the fixing portion 130. The setting of the reinforcing ribs 133 can reduce the weight of the fixing portion 130 while ensuring the strength of the fixing portion 130.

[0041] like Figure 4 As shown in , the base 100 also includes an outer shell 140, which is sleeved on the inner sleeve 124, and the connection method between the outer shell 140 and the inner sleeve 124 includes any one of a threaded connection, a snap-fit connection or a magnetic connection. The outer shell 140 serves to further fix the fixing part 130 and can make the external structure of the base 100 simpler.

[0042] In some embodiments, the housing 140 is in a conical cylindrical shape, and the shape of the fixing portion 130 matches the shape of the housing 140 , so that the housing 140 can fully contact the fixing portion 130 .

[0043] Please refer to Figure 4 In one embodiment, a first bevel gear set 125 is provided on the outer side of the inner sleeve 124, and a second bevel gear set 141 is provided on the inner side of the shell 140. The first bevel gear set 125 and the second bevel gear set 141 can be rotatably engaged to connect the shell 140 to the inner sleeve 124, and the shell 140 will simultaneously press the fixing portion 130. As the first bevel gear set 125 and the second bevel gear set 141 are engaged and tightened, the reaction force of the fixing portion 130 causes the shell 140 to tend to move upward, thereby causing the first bevel gear set 125 and the second bevel gear set 141 to self-lock, which can ensure a simple appearance while making the base 100 integrated. The rotatable engagement connection design can make the disassembly and assembly of the shell 140 easier and more convenient, and by pressing the fixing portion 130 to generate a reaction force, the first bevel gear set 125 and the second bevel gear set 141 can be self-locked, thereby making the installation structure of the base 100 more stable.

[0044] Combine Figure 4 As shown in , the steps of installing and disassembling the base 100 provided by the present invention are as follows:

[0045] First, adhere the adhesive sheet 110 to the connection area 123 of the bottom 120, then adhere the adhesive sheet 110 fixedly connected to the bottom 120 to the installation surface, and then install the fixing portion 130 in the inner sleeve 124 of the base 100. At this time, the external device can be connected to the connecting portion 132 of the fixing portion 130, and then the shell 140 is inserted into the inner sleeve 124. The shell 140 is rotated so that the first bevel gear group 125 on the shell 140 and the second bevel gear group 141 on the bottom 120 are engaged, so that the shell 140 presses the fixing portion 130, fixes the fixing portion 130, and completes the installation of the base 100. In some specific installation practices, In this example, the fixing portion 130 may include two sub-fixing portions 131. The two sub-fixing portions 131 are placed into the bottom 120. During the process of inserting the shell 140, the two sub-fixing portions 131 will be covered by the shell 140 and squeezed toward the middle, so that the two sub-fixing portions 131 are fastened together and fixed relative to the bottom 120. When the two sub-fixing portions 131 tend to separate, since the shell 140 is in a conical cylindrical shape, the shell 140 tends to move outward. Since the first bevel tooth group 125 and the second bevel tooth group 141 can be self-locking, this tendency will be prevented, so that the two sub-fixing portions 131 remain fixed relative to the bottom 120.

[0046] When the base 100 needs to be disassembled, the shell 140 is first rotated to disengage the first bevel gear group 125 and the second bevel gear group 141, and the shell 140 is detached from the bottom 120. Then, the external device is detached from the connecting portion 132 of the fixing portion 130, and then the fixing portion 130 is detached from the bottom 120. Then, the round head end 111 of the adhesive sheet 110 is peeled off, and the adhesive sheet 110 is stretched radially along the spiral structure of the adhesive sheet 110 so that the adhesive sheet 110 becomes thinner due to stretching and is separated from the mounting surface and the bottom 120. When the adhesive sheet 110 is completely separated from the mounting surface, the bottom 120 can be completely removed from the mounting surface.

[0047] Furthermore, in some specific application scenarios, if the base 100 provided by the present invention is used to be assembled and connected with an external device such as a robotic arm, the base 100 can be fixed to the surface to be installed, and the mounting part of the robotic arm can be rotated and engaged with the connecting part 132 on the sub-fixing part 131, so that the robotic arm can be fixedly installed on the base 100.

[0048] Specifically, the robotic arm is in direct contact with the fixing portion 130, and the operation of the robotic arm will apply a certain force to the fixing portion 130. During this process, since the fixing portion 130 is fixed between the shell 140 and the bottom 120, the shell 140 and the bottom 120 are fixed in an oblique tooth engagement manner, similar to a threaded connection, and a self-locking phenomenon can be formed after being subjected to force, so that the base 100 as a whole can be more firmly fixed on the surface to be installed.

[0049] Compared with the prior art, the base provided by the present invention has the following advantages:

[0050] 1. The present invention provides a base comprising a fixed portion, a bottom, and an outer shell. The bottom is provided with an inner sleeve, the fixed portion is sleeved within the inner sleeve, and the outer shell is sleeved on the outer surface of the fixed portion and is detachably connected to the inner sleeve. An adhesive sheet is also provided on the side of the bottom away from the fixed portion. The outer shell presses against the fixed portion, further securing it, making the base a stable entity, simplifying the external structure, and achieving integration.

[0051] 2. The fixing part includes one or more sub-fixing parts, each of which is provided with a connecting part that can be connected to a robot arm; at the same time, the fixing part is a hollow structure with reinforcing ribs inside, so that it can reduce weight while maintaining sufficient rigidity.

[0052] 3. The present invention provides a base having a through-hole formed in the bottom portion, forming a connection area outside the through-hole. A portion of the adhesive sheet is connected to the connection area, while another portion extends into the through-hole. A hollow area exists between the adhesive sheet extending into the through-hole and the through-hole. The edge of the adhesive sheet is first peeled off at the hollow area, and the adhesive sheet is stretched to thin it at a critical point. The adhesive sheet can then be gradually torn off in the tearing direction with minimal effort. Therefore, the base can be removed without applying direct force to the bottom portion.

[0053] 4. The adhesive sheet is in a spiral shape. Compared with a straight line structure, the spiral structure can be gradually disassembled along the spiral direction to avoid the tangential force component parallel to the plane of the adhesive sheet offsetting the pulling force applied by the human hand, thereby further saving effort during disassembly.

[0054] 5. In the present invention, the structure of the adhesive sheet is further defined, wherein the pointed end located on the outside of the spiral linear structure is a pointed structure. Starting from the pointed end, the line width gradually increases from one end to the inner rounded end to form a rounded structure with a certain length. The pointed end and a portion of the inner rounded end are connected to the connecting area. By peeling off the inner rounded end, the outer pointed end is gradually reached. Since the line width gradually decreases, the adhesive force applied to the adhesive sheet during the peeling process also gradually decreases, thereby allowing the base to be removed quickly and effortlessly.

[0055] 6. A first helical tooth group is provided on the outer side of the inner sleeve, and a second helical tooth group is provided on the inner side of the outer shell. The first helical tooth group and the second helical tooth group can be rotatably engaged to connect the outer shell to the inner sleeve. When the fixing portion tends to drive the outer shell to move upward, the first helical tooth group and the second helical tooth group will produce a self-locking phenomenon due to their inclination, so that the inner sleeve and the outer shell remain firmly connected, and the fixing portion remains in a stable state.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
