Description

Technical Field

[0001] This application relates to the field of movable display devices, and more particularly to a movable counterweight base and a display device. Background Technology

[0002] The display device is equipped with casters on its base to enable movement, allowing it to be moved to the appropriate area for use as needed.

[0003] However, the caster installation scheme for display devices in related technologies requires multiple installation operations, has a complex structure, and requires a large number of bolts for fixing. This not only increases material costs but also makes assembly troublesome and reduces assembly efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a movable counterweight base and a display device to improve assembly efficiency and reduce costs.

[0005] To achieve the above objectives, this application provides a movable counterweight base, comprising a front shell, a bottom shell, a counterweight block, multiple casters, and multiple locking components. The front shell and the bottom shell are assembled as a single unit to form a receiving cavity. The counterweight block is disposed within the receiving cavity. The multiple casters are disposed on the outer wall of the shell. The multiple locking components correspond one-to-one with the multiple casters and are used to lock the multiple casters. Each locking component includes a locking plate and multiple locking members. The locking plate is disposed on the side of the counterweight block near the front shell. The multiple locking members pass sequentially through the casters, the bottom shell, the counterweight block, and the locking plate to fix the casters, the bottom shell, the counterweight block, and the locking plate. The inner wall of the front shell has multiple abutting members that abut against the locking plate.

[0006] The technical solution provided in this application uses locking components that pass sequentially through the caster, base, counterweight, and locking plate to simultaneously fix the caster, base, counterweight, and locking plate. Compared to connecting the locking plate, base, and counterweight separately, or connecting the locking plate, counterweight, and caster separately, this reduces the number of locking components and the number of slots on the locking plate and counterweight, thereby simplifying the product structure, reducing assembly steps, improving assembly efficiency, and lowering costs.

[0007] Meanwhile, by setting multiple abutment parts on the inner wall of the faceplate, which abut against the locking plate, the locking plate is prevented from falling off when the movable counterweight base is rotated 180° for bottom locking. Compared with the existing method of attaching foam, the structure of this application is simpler, with fewer parts, which can further reduce assembly steps, improve assembly efficiency, and reduce material costs.

[0008] Optionally, the counterweight has multiple inner grooves on the side facing the face shell, and the locking plate is disposed in the inner grooves.

[0009] The above solution allows for the stable placement of the locking components while preventing interference between the locking plate and the faceplate, thus avoiding any impact on the assembly of the faceplate.

[0010] Optionally, the number of locking elements is at least two, the inner groove has at least two through holes; the locking plate includes a first plate body and at least two positioning pins; the plate body is disposed in the inner groove; the two positioning pins are inserted into the through holes, and the locking elements pass through the caster, the bottom shell and the positioning pins of the locking plate to fix the caster.

[0011] The above method utilizes positioning pins to accurately position the locking components, ensuring their precise placement. Furthermore, the positioning pins also serve a connecting function, simplifying the structure.

[0012] Optionally, the number of locking elements is at least three, and the inner groove has at least three through holes; the locking plate includes a first plate body and at least two positioning pins, the first plate body is disposed in the inner groove and has at least one threaded hole, the positioning pin is inserted into the through hole, at least two of the locking elements pass through the caster, the bottom shell and at least two of the positioning pins respectively and are connected, and at least one of the locking elements passes through the caster, the bottom shell and the through hole and is connected to the threaded hole.

[0013] With the above solution, the locking component can be connected to both the positioning pin and the threaded hole on the locking component, thereby reducing the number of positioning pins required, reducing material usage, and lowering costs.

[0014] Optionally, the thickness of the first plate is in the range of 1.8mm-2.2mm.

[0015] The above method ensures the mechanical strength of the locking components.

[0016] Optionally, the inner groove has multiple through holes, the locking plate includes a second plate body and multiple flanged bud holes, the flange of the flanged bud holes is inserted into the through holes, and the locking member passes through the caster, the bottom shell and the through holes in sequence and is connected to the flanged bud holes to fix the caster.

[0017] The above solution creates flanged holes on the locking plate using a flanged and budded method. This allows the locking plate to be positioned and installed using the flanged and through-hole connections, and also facilitates connection. Furthermore, the forming process of the flanged and budded holes is simple, convenient for production and processing, and allows for a thinner second plate, thus reducing material costs and preventing the second plate from being too thick and protruding from the inner groove, which could interfere with the normal assembly of the front shell.

[0018] Optionally, the thickness of the second plate is in the range of 1.3mm-1.7mm.

[0019] The above solution ensures the mechanical strength of the locking components without wasting raw materials.

[0020] Optionally, the abutment and the front shell are designed as a single unit.

[0021] The above solution can ensure the connection strength between the abutment and the shell, and also facilitate the processing and forming of the abutment, thereby reducing production costs.

[0022] Optionally, the inner wall of the faceplate has a plurality of first ribs, the first ribs abutting against the counterweight; and / or,

[0023] The inner wall of the bottom shell has a plurality of second ribs, which abut against the counterweight.

[0024] The above method can prevent the counterweight from shaking and ensure the stability of the counterweight installation.

[0025] Optionally, the bottom shell is recessed towards the counterweight to form a plurality of placement slots, and the casters are disposed in the placement slots.

[0026] The above solution lowers the center of gravity of the base, increasing its stability.

[0027] To achieve the above objectives, this application also provides a movable display device, including the aforementioned movable counterweight base. Attached Figure Description

[0040] like Figure 1As shown, the base of the display device in the related technology includes a front shell, a bottom shell, a counterweight, casters, caster brackets, and supporting foam. The caster bracket has six mounting posts, which are inserted into the six holes of the counterweight for positioning. The supporting foam is then attached to the side of the caster bracket adjacent to the front shell, and the front shell is fixed to the bottom shell. At this point, the front shell abuts against the caster bracket through the foam, limiting the vertical movement of the caster bracket and preventing it from detaching after rotating 180°. The base with the front shell attached is then rotated 180°, with the bottom shell facing upwards. Two bolts are used to connect two of the positioning posts to the bottom shell, thus fixing the caster bracket to the bottom shell. Four bolts pass through the mounting holes on the casters and connect to the other four positioning posts, thus fixing the casters to the counterweight via the caster bracket. It is evident that the caster bracket used to connect the casters in this solution requires two installations, has a complex fixing method, and requires 30 bolts to fix 5 casters. In addition, additional support foam is needed to support the fixing plate, making the structure complex and assembly troublesome.

[0041] Therefore, this application redesigns the caster installation method. Specifically, flanged ferrule holes are formed on the caster bracket. The flanged portion of these holes mates with the through holes on the counterweight block, allowing for pre-positioning and installation on the counterweight block, thus simplifying the caster bracket structure. Furthermore, multiple abutment members are provided on the inner wall of the faceplate to abut the caster bracket, preventing it from detaching after rotating 180°. This eliminates the need for additional foam padding, simplifying the assembly process. Simultaneously, bolts are sequentially passed through the mounting holes on the caster, the base shell, and the counterweight block to connect to the caster bracket. This allows for simultaneous connection of the caster, base shell, and counterweight block, eliminating the need to distinguish between connecting the caster bracket to the base shell and connecting the caster to the counterweight block. This reduces the number of bolts and threaded holes on the caster bracket, further simplifying the structure and assembly process, thereby improving assembly efficiency and reducing costs.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0043] Please refer to Figures 2 to 5As shown in the figure, an embodiment of this application provides a movable counterweight base 100, which includes a front shell 110, a bottom shell 120, a counterweight block 130, multiple casters 140, and multiple locking components 150. Each locking component 150 corresponds to one caster 140, and each locking component 150 locks one caster 140. Each locking component 150 includes multiple locking plates 151 and multiple locking elements 152. The locking plates 151 are disposed on the side of the counterweight block 130 near the front shell 110. The locking elements 152 pass sequentially through the casters 140, the bottom shell 120, the counterweight block 130, and the locking plates 151 to fix the casters 140, the bottom shell 120, the counterweight block 130, and the locking plates 151. The inner wall of the faceplate 110 has a plurality of abutting members 111, which abut against the locking plate 151. In this way, when the locking plate 151 is not connected by the locking member 152, the abutting members 111 can prevent the locking plate 151 from moving. Thus, when the movable counterweight base 100 is rotated 180° to lock the locking member 152, the problem of the locking plate 151 shifting can be avoided, so as to facilitate the installation of the locking member 152 from the outside.

[0044] Specifically, the movable counterweight base 100 of this application includes a front shell 110, a bottom shell 120, a counterweight block 130, casters 140, and locking components 150. The number of locking components 150 and casters 140 is both multiple and equal. Each locking component 150 locks one caster 140 to fix the caster 140 to the bottom shell 120, facilitating movement of the base by the caster 140. In this embodiment, the number of locking components 150 and casters 140 is five each, evenly distributed around the axis of the bottom shell 120, so that the movable counterweight base can be stably placed on a flat surface and move stably. The front shell 110 and the bottom shell 120 are assembled together to form a receiving cavity 112, which is used to receive the counterweight block 130. The assembly method between the front shell 110 and the bottom shell 120 can be a snap-fit ​​connection. Multiple snap-fit ​​parts (not shown in the figure) extend from the edge of the front shell 110 towards the bottom shell 120. The bottom shell 120 has multiple slots (not shown in the figure) that fit into the snap-fit ​​parts. The snap-fit ​​parts engage with the slots to assemble the bottom shell 120 and the front shell 110 together. The bottom shell 120 and the front shell 110 are connected by a snap-fit ​​mechanism to facilitate assembly and improve assembly efficiency. Casters 140 are mounted on the outer wall of the bottom shell 120 facing the ground. In use, the casters 140 are placed on the ground to facilitate stable rolling on a flat surface or ground, thereby moving the components above the casters 140.

[0045] In this embodiment, the locking plate 151 is also disposed within the receiving cavity 112, and the locking plate 151 is attached to the side of the counterweight 130 near the front shell 110, so that the counterweight 130 is located between the locking plate 151 and the bottom shell 120. The locking member 152 is installed from the outside of the bottom shell 120. During installation, the locking member 152 is passed through the caster 140, the bottom shell 120, the counterweight 130 and the locking member 152 in sequence to fix the caster 140, the bottom shell 120, the counterweight 130 and the locking plate 151 together, so that the caster 140 is completely fixed. The inner wall of the faceplate 110 facing the counterweight has multiple abutment members 111, with a total of five abutment members 111. Each abutment member 111 abuts against a locking plate 151 to prevent the locking plate 151 from disengaging from the counterweight 130 when the base is flipped over and the locking member 152 is installed from the outside of the base shell 120, thus ensuring that the locking member 152 can be completely fixed to the locking plate 151. In some optional embodiments, the locking member 152 can be a bolt, which passes sequentially from one side of the base shell 120 through the caster 140, the base shell 120, the counterweight 130, and the locking plate 151 to fix the caster 140.

[0046] During the assembly of the movable counterweight base of this application, the counterweight is first placed inside the base shell. Positioning structures can be provided between the counterweight and the base shell to facilitate the positioning and installation of the counterweight, ensuring that the holes (through holes 132) on the counterweight correspond to the holes on the base shell 120. Then, the locking plate 151 is placed on the counterweight 130, and the face shell 110 is installed on the base shell 120. At this time, the abutment 111 on the inner wall of the face shell 110 abuts against the locking plate 151 to position the locking plate 151 on the counterweight 130. The operator then flips the base shell 120 to the front and, from the outside, sequentially passes bolts through the caster 140, the base shell 120, and the counterweight 130 to connect with the locking plate 151, thus completely securing the caster 140. In this application, the installation process of caster 140 is reduced, and foam is eliminated, reducing material costs. At the same time, bolts simultaneously fix the caster, base, counterweight, and locking plate, eliminating the need to connect the locking plate, base, and counterweight separately first, and then connect the locking plate, counterweight, and caster separately. This reduces the number of bolts and the number of empty slots on the locking plate and counterweight, thereby reducing material and processing waste, reducing assembly times, improving assembly efficiency, and lowering costs.

[0047] In practical applications, the abutment 111 can be integrally designed with the face shell 110 using injection molding or other methods. This allows the abutment 111 to be molded as a single piece without the need for additional separate processing, simplifying the production process and avoiding secondary assembly. Alternatively, the abutment 111 can be designed separately from the face shell 110, with the abutment 111 and face shell 110 molded separately and then connected to each other.

[0048] Please refer to Figure 3 As shown, the counterweight 130 has multiple recesses 131 on the side facing the faceplate 110, and the locking plate 151 is disposed within the recesses 131. Thus, when the locking plate 151 is installed within the recesses 131, the locking plate 151 is recessed within the counterweight 130, preventing the locking plate 151 from protruding from the outer surface of the counterweight 130, thereby preventing interference between the locking plate 151 and the faceplate 110 and ensuring proper assembly of the faceplate 110. Specifically, five recesses 131 are evenly distributed on the side of the counterweight 130 facing the faceplate. The recesses 131 are used to stably place the locking plate 151 to facilitate subsequent assembly operations.

[0049] Please refer to Figure 3 , Figure 5 and Figure 7 As shown, in an optional embodiment, the number of locking members 152 is at least two, and the inner groove 131 of the counterweight block 130 has at least two through holes 132. The locking plate 151 includes at least two positioning posts 1511 and a first plate body 1512. The first plate body 1512 is disposed in the inner groove 131, and the two positioning posts 1511 are inserted into the through holes 132. The locking members 152 pass through the caster 140, the bottom shell 120, and the positioning posts 1511 of the locking plate 151 to fix the caster 140. That is, the locking members 152 may be connected only to the positioning posts 1511.

[0050] In another alternative embodiment, the number of locking elements is at least three, and the inner groove 131 has at least three through holes 132. The locking plate 151 includes a first plate body 1512 and at least two positioning pins 1511. The first plate body 1512 is disposed within the inner groove 131 and has at least one threaded hole. The positioning pins 1511 are inserted into the through holes 132. At least two locking elements 152 pass through the caster 140, the base shell 120, and the at least two positioning pins 1511 respectively and are connected. At least one locking element 152 passes through the caster 140, the base shell 120, and the through hole 132 and is connected to the threaded hole. That is, the locking element 152 can be simultaneously connected to both the positioning pin 1511 and its threaded hole.

[0051] Specifically, each inner groove 131 of the counterweight 130 has multiple through holes 132, the number of which is the same as the number of locking elements 152. In this embodiment, the number of locking elements 152 is set to 4, with 4 through holes 132 in each inner groove 131. The locking plate 151 includes a square first plate 1512 and two positioning posts 1511. The first plate 1512 and the two positioning posts 1511 are integrally formed, and the first plate 1512 is also provided with two threaded holes. The two threaded holes are located at two opposite corners of the first plate 1512, and the two positioning posts 1511 are located at opposite corners of the first plate 1512. The two positioning posts 1511 are inserted into the two opposite through holes 132 in the inner groove 131, and the two positioning posts 1511 provide a positioning effect, making it convenient for the operator to position and install the locking plate 151 in the inner groove 131. During assembly, the operator inserts two positioning pins 1511 into two through holes 132, so that the first plate 1512 is placed on the bottom wall of the inner groove 131. Then, the operator installs the face shell 110 on the bottom shell 120, so that the abutment member 111 inside the face shell 110 abuts against the first plate 1512. At this time, the bottom shell 120 is flipped so that the bottom shell 120 faces upward. Then, two of the locking members 152 are passed through the caster 140, the bottom shell 120 and connected to the positioning pins 1511. The other two locking members 152 are passed through the caster 140, the bottom shell 120 and connected to the threaded holes to fix the caster 140. In this embodiment, five casters 140 are used, and a total of 20 bolts are used, which is significantly reduced compared to the 30 bolts in the original solution. The stability and convenience of fixing the casters 140 are also improved.

[0052] The thickness of the first plate 1512 is in the range of 1.8-2.2 mm. In this embodiment, the locking element 152 is a bolt, and the positioning pin 1511 is a stud. The stud and the opening on the first plate 1512 need to be directly tapped. Since the stud needs to be directly tapped, the thickness of the first plate 1512 in this solution is relatively thick to increase the mechanical stability of the fixing between the bolt and the first plate 1512. In some embodiments, the thickness of the first plate 1512 can be set to 2 mm.

[0053] Please refer to Figure 3 , Figure 5 and Figure 8 As shown, in another optional embodiment, each inner groove 131 on the counterweight 130 has a plurality of through holes 132, the locking plate 151 includes a second plate body 1513 and a plurality of flanged bud holes 1514, the flanges of the flanged bud holes 1514 are inserted into the through holes, and the locking member 152 passes through the caster 140, the bottom shell 120 and the through holes 132 in sequence and connects to the flanged bud holes 1514 to fix the caster 140.

[0054] Specifically, in this embodiment, the locking plate 151 includes an integrally formed second plate body 1513 and a plurality of flanged bud holes 1514. The second plate body 1513 is a square plate component, and the number of flanged bud holes 1514 is set to 4, with the 4 flanged bud holes 1514 respectively located at the four corners of the second plate body 1513. During assembly, the operator inserts the flanged bud hole 1514 into the through hole, so that the second plate 1513 fits against the bottom wall of the inner groove 131. Then, the face shell 110 is snapped onto the bottom shell 120, so that the counterweight 130 is placed in the receiving cavity 112 formed by the face shell 110 and the bottom shell 120. At this time, the abutment 111 on the inner wall of the face shell 110 abuts against the second plate 1513, so that the position of the second plate 1513 is fixed. Then, the operator flips the bottom shell 120 to face upward, and then installs the locking member 152 from the outside, so that the locking member 152 passes through the caster 140, the bottom shell 120, and the flanged bud hole 1514 from the outside to the inside, so that the caster 140 is completely fixed.

[0055] In this embodiment, the thickness of the second plate 1513 is set between 1.3 and 1.7 mm. Preferably, the thickness of the second plate 1513 is 1.5 mm, so as to ensure that the second plate 1513 meets the structural strength requirements while avoiding the second plate 1513 being too thick and protruding out of the inner groove 131, thus affecting the normal assembly of the face shell 110.

[0056] Please refer to Figure 3 and Figure 6 As shown, in an optional embodiment, the inner wall of the face shell 110 has a plurality of first ribs 113, which abut against the counterweight 130. And / or the inner wall of the bottom shell 120 has a plurality of second ribs 121, which abut against the counterweight 130.

[0057] Specifically, in this embodiment, the inner wall of the face shell 110 has multiple first ribs 113, which abut against the upper surface of the counterweight 130. The inner wall of the bottom shell 120 has multiple second ribs 121, which abut against the lower surface of the counterweight 130. Since the upper and lower surfaces of the counterweight 130 have large areas, by providing the first ribs 113 and the second ribs 121, with the first ribs 113 abutting against the upper surface of the counterweight 130 and the second ribs 121 abutting against the lower surface of the counterweight 130, the counterweight 130 can be stably placed inside the face shell 110 and the bottom shell 120. It should be noted that, due to the manufacturing tolerances of the base shell 120, the top shell 110, and the counterweight 130, the counterweight 130 might wobble within the base shell 120 and the top shell 110 without the first rib 113 and the second rib 121. The counterweight 130 of this application can be stably fixed within the top shell 110 of the base shell 120 without wobbling, thus preventing the base from wobbling during movement and causing instability of the center of gravity.

[0058] Please refer to Figure 3 and Figure 9 As shown, in an optional embodiment, the bottom shell 120 is recessed toward the counterweight 130 to form a plurality of placement slots 122, and the caster 140 is disposed in the placement slots 122.

[0059] Specifically, the base shell 120 is recessed upwards to form five upward-facing placement slots 122, each slot 122 for mounting a caster 140. During assembly, the casters 140 are placed one by one on the bottom wall of the placement slot 122, and locking members 152 pass sequentially from the outside through the bottom wall of each placement slot 122, the counterweight 130, and the locking plate 151 to completely secure each caster 140. By placing the casters 140 within the placement slots 122, this application lowers the center of gravity of the base, bringing the entire base closer to the ground, further ensuring that the base does not tip over during movement and improving the stability of the device.

[0060] In practical applications, the bottom surface of the placement groove 122 can also be provided with an upwardly recessed stepped groove. The shape of the stepped groove matches the shape of the connecting plate of the caster 140, so that the caster 140 can be positioned and placed in the placement groove 122 by matching the shape of its connecting plate with the stepped groove, so as to ensure that the holes on the connecting plate of the caster 140 correspond to the holes on the bottom shell.

[0061] This application also relates to a display device, which includes the aforementioned movable counterweight base 100, support rod, and display screen. One end of the support rod is connected to the base, and the other end is connected to the display screen. The movable counterweight base 100 of the display device of this application has a simpler structure and facilitates the assembly of the casters 140, reducing the difficulty of assembling the casters 140 and lowering material costs.

[0062] This application also relates to an electronic device having the aforementioned movable counterweight base 100, which supports components above it. The electronic device can be an interactive flat panel, a display, or a recording stand, etc.
