Abstract
Description
Technical Field
[0001] The present application relates to the field of wearable devices, and in particular to watch straps and wearable devices. Background Art
[0002] Wearable devices are portable devices worn directly on the user. They are more than just hardware; they also enable powerful functionality through software support, data interaction, and cloud-based interaction. Wearable devices are poised to revolutionize our lives and our perceptions.
[0003] For example, existing wearable devices, such as smartwatches and smart bracelets, typically come with a strap that allows users to wear them on their wrists. However, wrists vary in size, while the strap length is fixed. This results in a poor fit between the smartwatch and the user's wrist, reducing the user experience.
[0004] Among them, the watch strap in the related art is composed of multiple unit sections, and it is difficult to disassemble adjacent unit sections, which makes it difficult for users to adjust the length of the watch strap by disassembling the unit sections. Summary of the Invention
[0005] The embodiments of the present application provide a watch strap and a wearable device, which can facilitate users to adjust the length of the watch strap themselves.
[0006] An embodiment of the present application provides a watchband, comprising a plurality of unit sections, each of which comprises:
[0007] A main body portion, wherein the main body portion has a first accommodating groove;
[0008] a raised portion, the raised portion being connected to the main body portion and being disposed in the first receiving groove adjacent to the unit segment;
[0009] Two sets of pivotal assemblies, the two sets of pivotal assemblies being disposed opposite to each other on the side walls forming the first receiving groove and being capable of engaging with the protrusions of adjacent unit sections so as to pivotally connect the main body to the protrusions of adjacent unit sections; and
[0010] An unlocking assembly is at least partially disposed on the protruding portion and is capable of driving the protruding portion to separate from the pivoting assembly of the adjacent unit section, so that the protruding portion can be separated from the main body of the adjacent unit section.
[0011] An embodiment of the present application also provides a wearable device, which has the above-mentioned watch strap.
[0012] In an embodiment of the present application, the watch strap is formed by connecting multiple unit sections, each unit section has a main body and a protrusion, and a pivot assembly is provided on the main body. The pivot assembly can engage with the protrusion of the adjacent unit section to realize the pivot connection and locking of the two adjacent unit sections, thereby connecting the multiple unit sections in series to form a watch strap with a certain length; on the other hand, the embodiment of the present application also includes an unlocking assembly that is at least partially provided on the protrusion, and the unlocking assembly can separate the protrusion from the pivot assembly of the adjacent unit section, thereby realizing the disassembly of the two unit sections; it can be seen that the user can easily disassemble the unit sections on the watch strap by themselves to adjust the length of the watch strap.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.
[0027] Wearable devices are portable devices worn directly on the user's body. As technology continues to improve and demand grows, wearable devices are becoming more than just hardware devices. They can also achieve powerful functions through software support, data interaction, and cloud interaction. As a result, wearable devices are gaining increasing attention.
[0028] Please refer to Figure 1 , Figure 1 : is a structural diagram of a wearable device provided in an embodiment of the present application. The wearable device may be a smart watch, a smart bracelet or other device that can be worn on a user. The embodiment of the present application takes a smart watch as an example to further illustrate the technical solution of the wearable device. The wearable device may include a dial 10 and a strap 20. The opposite ends of the dial 10 are connected to the strap 20, so that the smart watch can be worn on the user's hand. It will be understood that the embodiment of the present application does not limit the specific type of wearable device. For example, the wearable device may also be a mechanical watch, an electronic watch, or other device that can be worn with a strap 20.
[0029] Please refer to Figure 2 , Figure 2 yes Figure 1Schematic diagram of the connection structure of two unit segments of the wearable device shown. The strap 20 includes a plurality of unit segments 210, each of which may include a main body 211, a raised portion 212, a pivot assembly 213, and an unlocking assembly 214. The main body 211 may have a first receiving groove 2111. The raised portion 212 is connected to the main body 211 and is located on the side of the main body 211 facing away from the first receiving groove 2111. The raised portion 212 is arranged in the first receiving groove 2111 of the adjacent unit segment 210, so that the raised portion 212 partially extends into the first receiving groove 2111 of the adjacent unit segment 210. Two sets of pivot assemblies 213 are arranged relative to each other on the side walls forming the first receiving groove 2111, and can engage with the raised portions 212 of the adjacent unit segments 210 to pivotally connect the main body 211 to the raised portions 212 of the adjacent unit segments 210. The unlocking assembly 214 is at least partially disposed on the protrusion 212 and drives the protrusion 212 to separate from the engaged sub-pivot assembly 213 so that the protrusion 212 can be separated from the main body 211 of the adjacent unit segment 210, that is, the two adjacent unit segments 210 can be disassembled.
[0030] It is understandable that the watch strap 20 in the related art is composed of a plurality of unit sections 210, and the plurality of unit sections 210 are connected by pins inserted into the unit sections 210. Therefore, when the watch strap 20 in the related art is disassembled, a special meter adjuster is required to remove the pin between the two unit sections 210. Therefore, the watch strap 20 in the related art has the disadvantages of being inconvenient to disassemble and being overly dependent on the meter adjuster. In contrast, the watch strap 20 provided in the embodiment of the present application can unlock two adjacent unit sections 210 through the unlocking component 214. It can be seen that the watch strap 20 provided in the embodiment of the present application has the advantage of being easy to disassemble between the unit sections 210 to adjust the overall length of the watch strap 20.
[0031] Please refer to Figure 3 and Figure 4 , Figure 3 for Figure 2 The schematic diagram of the state when the two unit sections are separated is shown. Figure 4 for Figure 2 The diagram of the intermediate state of the two unit sections when they are installed is shown in FIG. Figure 3 As shown, the sidewalls of the main body 211 forming the first receiving groove 2111 may include a first sidewall 2113 and a second sidewall 2114. A set of pivotal components 213 are disposed on the first sidewall 2113 and the second sidewall 2114 opposite to each other.
[0032] like Figure 3As shown, the raised portion 212 can be connected to the main body 211. For example, the raised portion 212 can be integrally formed with the main body 211 through milling, or can be separately formed and then screwed in place. The raised portion 212 is located on the side of the main body 211 facing away from the first receiving groove 2111. When two unit segments 210 are connected, the raised portion 212 can be inserted into the first receiving groove 2111 of another adjacent unit segment 210. Multiple unit segments 210 can be connected in sequence to form the watchband 20.
[0033] like Figure 3 As shown, the raised portion 212 may have a third side wall 2121 , a fourth side wall 2122 and a fifth side wall 2123 connected in sequence. The third side wall 2121 and the fifth side wall 2123 are both connected to the main body portion 211 .
[0034] Please refer to Figure 5 and Figure 6 , Figure 5 yes Figure 2 The side view of the two unit sections is shown. Figure 6 for Figure 5 The cross-sectional view of the two unit sections along the BB direction is shown. A pivot hole 2124 is provided on the third side wall 2121 and the fifth side wall 2123. In the embodiment of the present application, the two pivot holes 2124 are coaxially arranged. The two pivot holes 2124 can be connected or independent of each other. When the two unit sections 210 are connected, the two sets of pivot assemblies 213 partially extend into one of the pivot holes 2124 of the adjacent protrusions 212 to achieve engagement. Furthermore, the protrusion 212 can rotate around the axis of the pivot hole 2124 to achieve the pivot connection of the protrusion 212 to the main body 211 of the adjacent unit section 210.
[0035] like Figure 6 As shown, the pivot assembly 213 may include a first elastic member 2131 and a pivot rod 2132. The first elastic member 2131 is provided on the side wall forming the first receiving groove 2111. The pivot rod 2132 can be driven by the first elastic member 2131 to move, thereby causing the first end 21322 of the pivot rod 2132 along its axial direction to move into the first receiving groove 2111. Therefore, when the protrusion 212 of the adjacent unit section 210 is inserted into the first receiving groove 2111 of the main body 211, the pivot rod 2132 can engage with the adjacent unit section 210 to realize the pivot connection of the two unit sections 210. Below, the first elastic member 2131 and the pivot rod 2132 provided in the embodiment of the present application are further described in detail with reference to the accompanying drawings.
[0036] For example, Figure 6As shown, mounting holes 2115 are formed on both the first side wall 2113 and the second side wall 2114. The mounting holes 2115 are connected to the first accommodating groove 2111. When two unit segments 210 are pivotally fixed, the two mounting holes 2115 are coaxially arranged with the two pivot holes 2124 of the adjacent unit segments 210. Each of the mounting holes 2115 is used to mount a set of pivot assemblies 213. The mounting holes 2115 can be blind holes or through holes. The following embodiments of the present application are described in detail using the mounting holes 2115 as through holes as an example.
[0037] like Figure 6 As shown, a stop structure 2133 is provided on the side of the mounting hole 2115 facing away from the first receiving groove 2111. The stop structure 2133 may be a fixing plug, which is secured to the mounting hole 2115 through an interference fit. When the fixing plug is connected to the mounting hole 2115 through an interference fit, the surface of the fixing plug facing away from the first receiving groove 2111 smoothly connects with the outer surface of the main body 211 to form a smooth surface. This smooth surface is then polished, brushed, or sandblasted to reduce the visibility of the seam between the surface of the fixing plug facing away from the first receiving groove 2111 and the outer surface of the main body 211, ultimately improving the aesthetics of the watchband 20. Of course, the specific structure of the stop structure 2133 is not limited in this embodiment of the application. For example, the stop structure 2133 may also be a screw. Accordingly, the side wall forming the mounting hole 2115 facing away from the first receiving groove 2111 is provided with internal threads, and the screw is threadedly engaged into the first receiving groove 2111 to secure the watchband 20.
[0038] like Figure 6 As shown, the first elastic member 2131 can be an elastic member such as a helical compression spring, a disc spring, or a leaf spring. The first elastic members 2131 of the two sets of pivotal assemblies 213 are respectively embedded in the corresponding mounting holes 2115. The end of the first elastic member 2131 away from the first receiving groove 2111 abuts against the stop structure 2133.
[0039] like Figure 6 As shown, the pivot rod 2132 can have a second end 21321 and a first end 21322 that are relatively arranged along the axial direction of the mounting hole 2115, and is partially slidably installed in the mounting hole 2115, so that the pivot rod 2132 can move along the axial direction of the mounting hole 2115.
[0040] like Figure 6As shown, the second end 21321 of the pivot rod 2132 abuts against the end of the first elastic member 2131 away from the stop structure 2133. When two unit segments 210 are connected, the first elastic member 2131 is in an extended state, the second end 21321 of the pivot rod 2132 is located in the mounting hole 2115, and the first end 21322 is inserted into the pivot hole 2124 of the adjacent unit segment 210. Consequently, the pivot assembly 213 engages with the main body 211 of the adjacent unit segment 210, completing the pivotal connection and fixation of the two adjacent unit segments 210.
[0041] In the embodiments of this application, Figure 6 As shown, the mounting hole 2115 can be a stepped hole having a small diameter section 21151 proximal to the first accommodating groove 2111 and a large diameter section 21152 distal to the first accommodating groove 2111. The inner diameter of the large diameter section 21152 is larger than that of the small diameter section 21151. A limiting shoulder 21324 is formed on the second end 21321 of the pivot rod 2132. The limiting shoulder 21324 is clearance-matched with the large diameter section 21152, allowing the limiting shoulder 21324 to slide within the large diameter section 21152. The outer diameter of the large diameter section 21152 is larger than the inner diameter of the small diameter section 21151, preventing the pivot rod 2132 from falling out and being lost after completing its movement into the first accommodating groove 2111.
[0042] The installation process of the pivot assembly 213 is as follows: First, the first end 21322 of the pivot rod 2132 is sequentially passed through the large-diameter section 21152 and the small-diameter section 21151, and then slid into the first receiving groove 2111. Then, the first elastic member 2131 is installed into the large-diameter section 21152. Finally, the fixing plug is installed and fixed into the large-diameter section 21152, so that the end of the first elastic member 2131 away from the first receiving groove 2111 abuts the fixing plug, and the end of the first elastic member 2131 closer to the first receiving groove 2111 rests on the second end 21321 of the pivot rod 2132.
[0043] When the pivot rod 2132 is driven by the unlocking assembly 214, the pivot rod 2132 as a whole slides from the first receiving groove 2111 into the mounting hole 2115 to a specified position. The first end 21322 of the pivot rod 2132 exits the pivot hole 2124 of the adjacent unit segment 210, and the first elastic member 2131 is compressed. As a result, the connection between the two adjacent unit segments 210 is severed, and the two adjacent unit segments 210 can be disassembled and separated. At this point, the pivot rod 2132 can either completely slide until it is completely within the mounting hole 2115 or partially outside the mounting hole 2115. Of course, in other specific embodiments, the pivot rod 2132 can also be fixedly connected to another adapter element, which is slidably mounted on the side wall forming the first receiving groove 2111. It is sufficient for the pivot rod 2132 to be able to achieve direct or indirect sliding connection with the side wall forming the first receiving groove 2111.
[0044] When the pivot rod 2132 is no longer driven by the unlocking assembly 214, the first elastic member 2131 returns to its original position and drives the pivot rod 2132 to slide from the mounting hole 2115 into the first receiving groove 2111 to a designated position. At this point, the first end 21322 of the pivot rod 2132 can be inserted into the pivot hole 2124 of the adjacent unit segment 210 to engage with the first end 21322, thereby achieving the pivotal connection and fixation of the two adjacent unit segments 210.
[0045] Thus, the watchband 20 can quickly engage or disengage the pivoting assembly 213 with the pivoting hole 2124 of the adjacent unit segment 210 through the unlocking assembly 214, thereby achieving the pivoting or disengagement of two adjacent unit segments 210. Therefore, the watchband 20 provided by the embodiment of the present application has the advantage of being easy to disassemble.
[0046] It is understood that when the first elastic member 2131 is in the extended state, the protrusion 212 of the adjacent unit segment 210 is blocked by the pivot rod 2132, thereby preventing the protrusion 212 from being inserted into the first receiving groove 2111 of the adjacent unit segment 210. In this case, the user needs to first press the pivot rod 2132 to retract the pivot rod 2132 into the pivot hole 2124 before the protrusion 212 of the adjacent unit segment 210 can be inserted into the first receiving groove 2111.
[0047] Please refer to Figure 7 and Figure 8 , Figure 7 yes Figure 2 Exploded view of the unit section shown. Figure 8 yes Figure 7 A schematic diagram of the structure of a pivoting rod of a unit segment is shown. To facilitate insertion of the protrusion 212 into the first receiving groove 2111 of the adjacent unit segment 210, a first chamfer is formed on the first end 21322 of the pivoting rod 2132. The first chamfer can be a fully rounded angle formed by the first end 21322 of the pivoting rod 2132, or a fully right angle formed by the first end 21322 of the pivoting rod 2132.
[0048] Therefore, if Figure 2 and Figure 3As shown, during the insertion of the protrusion 212 into the first receiving groove 2111 of the adjacent unit segment 210, the corners between the third side wall 2121 and the fourth side wall 2122, and the corners between the fourth side wall 2122 and the fifth side wall 2123 of the protrusion 212, abut against the inclined or curved surface formed by the first chamfer. Furthermore, the force of the protrusion 212 inserting into the adjacent unit segment 210 is decomposed by the inclined or curved surface formed by the first chamfer of the adjacent unit segment 210 into a component force that drives the pivot rod 2132 of the adjacent unit segment 210 to retract into the corresponding mounting hole 2115, and the first elastic member 2131 of the adjacent unit segment 210 is compressed accordingly. After the two unit segments 210 are assembled in place, the pivot holes 2124 are coaxially arranged with the pivot rods 2132 of the adjacent unit segments 210 . The first elastic members 2131 of the adjacent unit segments 210 are restored and drive the corresponding pivot rods 2132 to be inserted into the pivot holes 2124 .
[0049] It can be seen that by setting the first chamfer at the first end 21322 of the pivot rod 2132, the user does not need to press the pivot rod 2132 during the process of connecting two adjacent unit sections 210, thereby allowing the user to conveniently connect two adjacent unit sections 210.
[0050] like Figure 8 As shown, the first end 21322 of the pivot rod 2132 has a first inclined surface 21323, which forms a first chamfer. In the embodiment of the present application, the first inclined surface 21323 is located on the side of the first end 21322 away from the protrusion 212. The first inclined surface 21323 is arranged at an angle relative to the axis of the pivot rod 2132. When two unit segments 210 are connected, the first chamfer can be completely or partially located within the pivot hole 2124 of the adjacent unit segment 210.
[0051] Therefore, when the protrusion 212 is inserted into the first receiving groove 2111 of the adjacent unit segment 210, the end of the protrusion 212 away from the main body 211 will abut against the first inclined surface 21323. The force of the protrusion 212 inserting into the adjacent unit segment 210 is then decomposed by the first inclined surface 21323 of the adjacent unit segment 210 into a component force that drives the pivot rod 2132 of the adjacent unit segment 210 to retract into the corresponding mounting hole 2115, and the first elastic member 2131 of the adjacent unit segment 210 is correspondingly compressed. After the two units 210 are fully assembled, the pivot hole 2124 is coaxially arranged with the pivot rod 2132 of the adjacent unit segment 210, and the first elastic member 2131 of the adjacent unit segment 210 is restored, driving the corresponding pivot rod 2132 to insert into the pivot hole 2124.
[0052] It can be seen that by setting the first chamfer at the first end 21322 of the pivot rod 2132, the user does not need to press the pivot rod 2132 during the process of connecting two adjacent unit sections 210, thereby allowing the user to conveniently connect two adjacent unit sections 210.
[0053] On the other hand, the partial chamfer of the first end 21322 has the advantage over a full chamfer in that, when two adjacent unit segments 210 are disassembled, the sidewalls forming the pivot hole 2124 abut against the circumferential side surface of the pivot rod 2132 of the adjacent unit segment 210. In this case, the sidewalls forming the pivot hole 2124 are coaxially arranged with the circumferential side surface of the pivot rod 2132 of the adjacent unit segment 210. Consequently, the protrusion 212, blocked by the circumferential side surface of the pivot rod 2132 of the adjacent unit segment 210, cannot detach from the adjacent unit segment 210, nor will it drive the pivot rod 2132 of the adjacent unit segment 210 into the mounting hole 2115, thereby improving the stability and reliability of the watchband 20 during use.
[0054] In addition, if Figure 8 As shown, when the first end 21322 is partially chamfered, in order to ensure that the first chamfer is always facing away from the protrusion 212 , the side wall forming the mounting hole 2115 can limit the rotational freedom of the pivot rod 2132 in the mounting hole 2115 .
[0055] Exemplarily, the second end 21321 of the pivot rod 2132 may be in the shape of a polygonal column or a flat shaft, and the large diameter section 21152 of the mounting hole 2115 may be in the shape of a polygonal column or a flat shaft that is clearance-fitted with the second end 21321 .
[0056] Taking the polygonal columnar shape as an example, the second end 21321 enables the pivot rod 2132 to slide only along the axis of the pivot rod 2132 within the mounting hole 2115, but not to rotate about the axis of the pivot rod 2132. It is understood that the radius of the inscribed circle of the polygon formed by the side walls forming the large-diameter section 21152 should be greater than the inner diameter of the small-diameter section 21151. Therefore, the radius of the inscribed circle of the polygon formed by the side walls forming the large-diameter section 21152 is also greater than the outer diameter of the first end 21322 of the pivot rod 2132, so that the first end 21322 of the pivot rod 2132 can sequentially pass through the large-diameter section 21152 and the small-diameter section 21151 before extending into the first receiving groove 2111. Of course, in some other specific embodiments, the second end 21321 may be connected to the side wall forming the mounting hole 2115 by a sliding key or the like to limit the rotational freedom of the pivot rod 2132 in the mounting hole 2115 .
[0057] like Figure 3As shown, to facilitate insertion of the protrusion 212 into the first receiving groove 2111 of the adjacent unit segment 210, in the embodiment of the present application, a second chamfer 2125 is provided at the junction of the third side wall 2121 and the fourth side wall 2122 of the protrusion 212. The second chamfer 2125 can be rounded or a chamfered right angle. A third chamfer 2126 is provided at the junction of the fourth side wall 2122 and the fifth side wall 2123. The third chamfer 2126 can be rounded or a chamfered right angle.
[0058] Therefore, if Figure 3 and Figure 4 As shown, when the protrusion 212 is inserted into the first receiving groove 2111 of the adjacent unit segment 210, the pivot rod 2132 of the adjacent unit segment 210 abuts against the inclined or curved surface formed by the second chamfer 2125 or the third chamfer 2126 of the protrusion 212. The inclined or curved surface formed by the second chamfer 2125 or the third chamfer 2126 then decomposes the force of the protrusion 212 inserting into the adjacent unit segment 210 into a component that drives the pivot rod 2132 of the adjacent unit segment 210 into the corresponding mounting hole 2115, compressing the first elastic member 2131 of the adjacent unit segment 210 accordingly. Once the two units 210 are fully assembled, the pivot hole 2124 and the pivot rod 2132 of the adjacent unit segment 210 become coaxially arranged, and the first elastic member 2131 of the adjacent unit segment 210 returns to its original position, driving the corresponding pivot rod 2132 to insert into the pivot hole 2124.
[0059] It can be seen that by providing the second chamfer 2125 and the third chamfer 2126 on the protrusion 212 , the user does not need to press the pivot rod 2132 during the process of connecting two adjacent unit sections 210 , thereby allowing the user to conveniently connect two adjacent unit sections 210 .
[0060] Of course, it can also be understood that in the embodiment of the present application, the above-mentioned first chamfer can be formed only on the first end 21322 of the pivot rod 2132, or the above-mentioned second chamfer 2125 and the third chamfer 2126 can be formed only on the protrusion 212, or the above-mentioned first chamfer 2125 and the above-mentioned third chamfer 2126 can be formed on the first end 21322 and the above-mentioned second chamfer 2125 and the third chamfer 2126 can be formed on the protrusion 212 at the same time.
[0061] In the above scheme of simultaneously forming the first chamfer on the first end 21322 and forming the second chamfer 2125 and the third chamfer 2126 on the protruding portion 212:
[0062] When the first elastic member 2131 is in the extended state, the projection of the second chamfer 2125 on the plane of the fourth side wall 2122 partially overlaps with the projection of the first chamfer on the same side of the protrusion 212. The projection of the third chamfer 2126 on the plane of the fourth side wall 2122 partially overlaps with the projection of the first chamfer on the same side of the protrusion 212.
[0063] When two unit segments 210 are connected, the first chamfer of the pivot rod 2132 is completely located in the pivot hole 2124 of the adjacent unit segment 210 .
[0064] Therefore, during the installation of two adjacent unit sections 210, the first chamfer and the second chamfer 2125 of the adjacent unit section 210, and the first chamfer and the third chamfer 2126 of the adjacent unit section 210 cooperate to drive the pivot rod 2132 to retract into the corresponding installation hole 2115 until the two unit sections 210 are assembled in place. At this time, the pivot rod 2132 is coaxially arranged with the pivot hole 2124 of the adjacent unit section 210, the first elastic member 2131 is restored, and drives the corresponding pivot rod 2132 to be inserted into the pivot hole 2124 of the adjacent unit section 210.
[0065] Therefore, when two adjacent unit segments 210 are connected, the sidewalls forming the pivot hole 2124 do not contact the first chamfer of the adjacent unit segment 210 , so that the protrusion 212 is locked on the pivot rod 2132 of the adjacent unit segment 210 .
[0066] It can be seen that the strap 20 provided in the embodiment of the present application not only has the advantage of being easy to disassemble, but also has the advantage of being firmly connected.
[0067] Please refer to Figures 9-12 , Figure 9 yes Figure 7 The schematic diagram of the structure of the main body and the raised part of the unit segment is shown. Figure 10 yes Figure 7 The schematic diagram of the structure of the main body, protrusion and partial unlocking assembly of the unit section is shown. Figure 11 yes Figure 7 Assembly drawing of the unlocking components of the unit section, Figure 12 yes Figure 11 Exploded view of the unlocked assembly of the unit section shown.
[0068] like Figure 11As shown, the unlocking assembly 214 may include a button 2141, two push rods 2142, and a second elastic member 2143. Pressing the button 2141 drives the two push rods 2142 to move away from each other. When the two push rods 2142 move away from each other, they push the pivot rods 2132 of adjacent unit segments 210 inserted into the pivot holes 2124 out of the pivot holes 2124, thereby unlocking the two adjacent unit segments 210. When the external force pressing the button 2141 is removed, the second elastic member 2143 drives the push rods 2142 and button 2141 to reset. The following describes the technical solution of the unlocking assembly 214 provided in the present embodiment in detail with reference to the accompanying drawings.
[0069] For example, Figure 9 As shown, the second receiving groove 216 may be provided through the raised portion 212 and the main body 211, or the raised portion 212 may be provided with a second receiving groove 216 alone. The second receiving groove 216 is connected to the pivot hole 2124. The unlocking assembly 214 is partially disposed in the second receiving groove 216, so the unlocking assembly 214 is at least partially disposed in the raised portion 212.
[0070] like Figure 12 As shown, two push rods 2142 are respectively slidably installed in a pivot hole 2124. The push rod 2142 can slide in the pivot hole 2124. The push rod 2142 includes a third end 21421 and a fourth end 21422 that are relatively arranged along the axis direction of the pivot hole 2124.
[0071] The third end 21421 can slide along the pivot hole 2124 to a portion located outside the protrusion 212. At this time, the push rod 2142 will be able to push the pivot rod 2132 of the adjacent unit segment 210 inserted into the pivot hole 2124 out of the pivot hole 2124, thereby separating the pivot assembly 213 of one unit segment 210 from the protrusion 212 of the adjacent unit segment 210, thereby allowing the two adjacent unit segments 210 to be unlocked.
[0072] It is understood that when the third end 21421 of the push rod 2142 moves outside the protrusion 212, if the travel of the push rod 2142 is incorrect, the push rod 2142 may be partially stuck in the mounting hole 2115 of the adjacent unit segment 210. Therefore, even if the pivot rod 2132 of one unit segment 210 is removed from the pivot hole 2124 of the adjacent unit segment 210, the two unit segments 210 cannot be unlocked.
[0073] For this reason, Figure 12As shown, a fourth chamfer 21423 is provided on the third end 21421. Therefore, when the protrusion 212 withdraws from the first receiving groove 2111 of the adjacent unit section 210, the curved surface or inclined surface formed by the fourth chamfer 21423 of the push rod 2142 will abut against the connection between the side wall forming the mounting hole 2115 and the side wall forming the first receiving groove 2111. Then, the inclined surface or curved surface formed by the fourth chamfer 21423 decomposes the force of the protrusion 212 withdrawing from the adjacent unit section 210 into a component of force that drives the push rod 2142 to retract into the pivot hole 2124. Ultimately, the push rod 2142 is separated from the mounting hole 2115 of the adjacent unit section 210. It can be seen that the fourth chamfer 21423 is provided on the push rod 2142 of the embodiment of the present application, which makes the disassembly of the two adjacent unit sections 210 easier and can also reduce the process requirements for the precision of each part during the manufacturing process.
[0074] On the other hand, Figure 9 As shown, a fifth chamfer 2116 is provided at the connection between the side wall forming the mounting hole 2115 and the side wall forming the first receiving groove 2111. Therefore, when the protrusion 212 withdraws from the first receiving groove 2111 of the adjacent unit section 210, the curved surface or inclined surface formed by the fifth chamfer 2116 will abut against the third end 21421 of the push rod 2142. Then, the inclined surface or curved surface formed by the fifth chamfer 2116 decomposes the force of the protrusion 212 withdrawing from the adjacent unit section 210 into a component force that drives the push rod 2142 to retract into the pivot hole 2124. Ultimately, the push rod 2142 is separated from the mounting hole 2115 of the adjacent unit section 210. It can be seen that the fourth chamfer 21423 is provided on the push rod 2142 of the embodiment of the present application, which makes the disassembly of the two adjacent unit sections 210 easier and can also reduce the process requirements for the precision of each part during the manufacturing process.
[0075] The push rod 2142 can also slide until it is completely located within the raised portion 212. At this point, the fourth end 21422 of the push rod 2142 is completely moved into the second receiving groove 216, and the third end 21421 of the push rod 2142 is located at the end of the pivot hole 2124 that is closer to the second receiving groove 216. Furthermore, the end of the pivot hole 2124 that is away from the second receiving groove 216 forms a relief position, allowing the pivot rod 2132 of the adjacent unit segment 210 to be inserted into the pivot hole 2124 for pivotal connection and fixation.
[0076] like Figure 12 As shown, the fourth end 21422 of each push rod 2142 is connected to a slider 2144. The slider 2144 is disposed in the second receiving groove 216, and the slider 2144 and the push rod 2142 are perpendicular to each other.
[0077] like Figure 10 and 11As shown, two second elastic members 2143 are disposed within the second receiving groove 216, parallel to the push rod 2142, with two sliders 2144 sandwiched between the two second elastic members 2143. For example, one end of the second elastic member 2143 abuts against the sidewall forming the second receiving groove 216, and the other end abuts against the slider 2144 on the same side. When a user presses the button 2141, the push rod 2142 slides out of the protrusion 212, and the slider 2144 follows the push rod 2142, compressing the second elastic members 2143. When the button 2141 is no longer under pressure, the second elastic member 2143 returns to its original position, causing the two sliders 2144 to move toward each other to reset. The two sliders 2144 then drive the two push rods 2142 toward each other to reset, and the two sliders 2144 also drive the button 2141 to reset.
[0078] The second elastic member 2143 can be an elastic member such as a leaf spring or a disc spring. In the embodiment of the present application, the second elastic member 2143 is a helical compression spring. To prevent the helical compression spring from shifting within the second accommodating groove 216, a first positioning notch 21441 is provided on the side of the slider 2144 that abuts the second elastic member 2143. The sidewalls forming the second accommodating groove 216 include a sixth sidewall facing the first positioning notch 21441, and a first positioning groove 2162 is provided on the sixth sidewall. One end of the second elastic member 2143 is disposed within the first positioning notch 2162, and the other end is disposed within the first positioning notch 21441.
[0079] Of course, in some other specific embodiments, the second elastic member 2143 may also be a hook spring, one end of which is hooked with one slider 2144, and the other end of which is hooked with the other slider 2144. Furthermore, the second elastic member 2143 can drive the two sliders 2144 to move toward each other.
[0080] The button 2141 can be inserted into the second receiving groove 216. For example, Figure 9 and 12 As shown, a slot cover 2145 is mounted on the side wall forming the second receiving slot 216, closing the second receiving slot 216. The slot cover 2145 is provided with a first opening 21451. The button 2141 is inserted into the first opening 21451, allowing the button 2141 to move in a direction perpendicular to the axis of the push rod 2142.
[0081] like Figure 12As shown, two first steps 21452 are disposed opposite each other on the side of the slot cover 2145 facing away from the exterior of the protrusion 212. The two first steps 21452 are of different sizes, and two second steps 2163 are disposed opposite each other on the sidewall forming the second accommodating groove 216. When the slot cover 2145 is connected to the sidewall forming the second accommodating groove 216, the two first steps 21452 and the two second steps 2163 are alternately disposed and arranged in a ring shape, thereby providing a good foolproofing effect during the installation of the slot cover 2145.
[0082] Two guide portions 21411 may be relatively provided on the button 2141 , and the two guide portions 21411 are slidably connected to the guide slots 21453 provided on the slot cover 2145 , so that the sliding process of the button 2141 is more stable and accurate.
[0083] The button 2141 includes a trapezoidal boss 21412 positioned within the second receiving groove 216. The trapezoidal boss 21412 includes second inclined surfaces 21413 located on two sides of the trapezoid. The distance between the two second inclined surfaces 21413 gradually decreases as they move away from the first opening 21451. Accordingly, the slider 2144 is formed with a third inclined surface 21442 that is parallel to the second inclined surface 21413 on the same side of the trapezoidal boss 21412.
[0084] Therefore, when the button 2141 is pressed toward the pivot rod 2132, the trapezoidal boss 21412 is inserted between the two sliders 2144. The second inclined surface 21413 and the third inclined surface 21442 cooperate to drive the two sliders 2144 to move in opposite directions. The slider 2144 then drives the push rod 2142 to move outside the pivot hole 2124, so that the push rod 2142 pushes the pivot rod 2132 of the adjacent unit segment 210 out of the pivot hole 2124. At this time, the second elastic member 2143 is compressed, and the two adjacent unit segments 210 are unlocked. When the external force on the button 2141 is removed, the second elastic member 2143 returns to its original position and drives the slider 2144 and the button 2141 to reset. Thus, the unlocking assembly 214 provided in the embodiment of the present application has the advantages of simple operation and easy assembly and disassembly of the unit segments 210.
[0085] like Figure 11 As shown, the unlocking assembly 214 may further include a third elastic member 2146. The third elastic member 2146 is disposed in the second receiving groove 216 and may be an elastic member such as a leaf spring, a disc spring or a helical compression spring. The third elastic member 2146 is arranged perpendicular to the axis of the push rod 2142. One end of the second elastic member 2143 abuts against a side of the case provided with a trapezoidal boss 21412, and the other end abuts against the side wall forming the second receiving groove 216. Therefore, when the user presses the button 2141, the third elastic member 2146 is compressed. When the external force on the button 2141 is removed, the third elastic member 2146 recovers and drives the button 2141 to reset.
[0086] Of course, to prevent displacement of the third elastic member 2146, a second positioning groove for accommodating the third elastic member 2146 is provided on the button 2141, and a third positioning groove for accommodating the third elastic member 2146 is provided on the bottom wall forming the second accommodating groove 216. Furthermore, two third elastic members 2146 may be provided, one on each side of the trapezoidal boss 21412, to ensure more uniform force when the button 2141 is reset.
