Alternatively, the connection detection structure is an electromagnetic induction structure, which includes a magnet located on the display and a magnetic sensor located on the mounting bracket. The magnetic sensor generates a low-level position detection signal when it detects that the magnetic field strength between the magnet and the magnetic sensor is greater than or equal to a preset field strength, to confirm that the display is connected to the mounting bracket.

[0033] The advantages are: by using a connection detection structure, this utility model can determine the connection status between the display and the mounting bracket and base, control different switches according to the connection status, select different batteries for power supply, thereby adaptively meeting the battery life performance of different usage scenarios and expanding the usage scenarios of mobile display devices.

[0034] According to an embodiment of the present utility model, the mobile display device includes a housing assembly comprising a first bottom shell, the first bottom shell comprising a first mounting portion, the first mounting portion being provided with a mounting seat, the mounting seat being used to connect the mounting frame, the mounting seat comprising an upper tube portion and a lower seat body, the upper tube portion being used to connect the mounting frame, and the lower seat body being used to connect the first mounting portion.

[0035] The advantages of this invention are: by setting a first bottom shell, which includes a first mounting part, and the first mounting part is provided with a mounting seat to connect the mounting frame, the shape of the first bottom shell can match the base, meet the arrangement requirements, and not affect the shape design of the base, making the design of the base more diverse. At the same time, the first bottom shell can improve the strength of the base, reduce the bending and deformation of the base, resist the overturning moment brought by the mounting frame and the display, and thus stably support the mounting frame and the display to meet the usage requirements.

[0036] The mounting base includes an upper tube and a lower body. Therefore, the upper tube can be used to connect the mounting frame, simplifying assembly and disassembly. The lower body can be used to connect the first bottom shell, which can improve the connection strength, allowing the first bottom shell and the lower body to withstand overturning moments and stably support the mounting frame and the display.

[0037] Moreover, the first base and the mounting base are usually two independent components, which can reduce manufacturing difficulty, meet diverse needs, and facilitate disassembly and assembly, reducing maintenance costs after damage.

[0038] According to an embodiment of the present invention, the lower base of the mobile display device has a length direction and a width direction. The length direction of the lower base is arranged along the left-right direction of the mobile display device, and the width direction of the lower base is arranged along the front-back direction of the mobile display device. The upper tube is located in the direction away from the second battery of the lower base.

[0039] The advantage of this invention is that by setting the length of the lower base along the left-right direction of the mobile display device, one end of the lower base is prevented from facing the center of the base, thus not affecting the arrangement of the second battery and allowing the second battery to maintain a larger size.

[0040] This invention strengthens the support in the left and right directions by setting the width of the lower base along the front-back direction of the mobile display device, that is, the two wide sides of the lower base are located on the left and right sides of the mobile display device, thereby improving the stability of the mobile display device in the left and right directions and making it less likely to tip over.

[0041] This invention positions the upper tube portion away from the lower base from the second battery, thereby connecting the mounting bracket to the edge of the base. This facilitates placing the display at the center of the base, bringing the center of gravity of the mobile display device closer to the center of the base, improving stability and preventing tipping.

[0042] According to an embodiment of the present invention, in the mobile display device, at least one of the upper and lower wide sides of the lower base has a clearance groove, which is a dovetail groove.

[0043] The advantages are: by setting the clearance groove, this utility model can reduce the average thickness of the lower seat, which is conducive to reducing material usage and also helps to reduce shrinkage during injection molding or casting, thereby improving the quality of the mounting seat.

[0044] Meanwhile, the design of the clearance groove does not reduce the solid volume of the four corners of the lower base, nor does it affect the connection strength between the mounting base and the first bottom shell.

[0045] Meanwhile, the design of the clearance slot reduces the obstruction of the first bottom shell, allowing for greater exposure of the first bottom shell and facilitating the opening of holes for the placement of wires and components.

[0046] According to an embodiment of the present utility model, the mobile display device includes a housing assembly comprising a first bottom shell, the first bottom shell comprising a first mounting portion, the first mounting portion being provided with a mounting seat, the mounting seat being used to connect the mounting frame, the mounting seat comprising a mounting hole for accommodating the bottom end of the mounting frame, and the bottom wall of the mounting hole being provided with mounting bolts for connecting the mounting frame and the first mounting portion.

[0047] The advantages of this invention are: by providing mounting holes with mounting bolts on the bottom wall of the mounting holes, the bottom end of the mounting bracket can be positioned using the mounting holes, thus reducing the risk of the mounting bracket tipping over in any direction. Simultaneously, the mounting bolts connect the bottom end of the mounting bracket, ensuring it fits snugly against the bottom wall of the mounting hole, preventing it from coming out and securing the bracket firmly. Furthermore, this design prevents overload and cracking of the inner surface of the mounting hole. For example, if the bottom end of the mounting bracket is only partially inserted into the mounting hole and tilts, it could easily damage the hole wall.

[0048] Meanwhile, in some embodiments that use pins and sockets to achieve conductive connections, the mounting bolts ensure a tight connection between the mounting base and the mounting bracket, and also help keep the pins inserted into the sockets, improving the reliability of current flow and signal transmission.

[0049] The mounting bolts connect the first mounting part and the mounting bracket, and also fasten the first bottom shell, mounting base and mounting bracket together, so that the first bottom shell, mounting base and mounting bracket are a whole, so that the first bottom shell can be used to resist the overturning moment, maintain the stability and strength of the mobile display device, and prevent it from tipping over and bending.

[0050] Mounting bolts are used to connect the mounting bracket and the first mounting part, and can also be used to connect and fix the second bottom shell together, so as to reduce the number of screws, simplify the installation, and at the same time meet the needs of installation and fastening.

[0051] According to an embodiment of the present invention, in a mobile display device, one of the mounting base and the mounting bracket includes a pin, and the other of the mounting base and the mounting bracket includes a slot for receiving the pin. The pin and the slot cooperate to determine the mounting angle of the mounting bracket relative to the mounting hole.

[0052] The advantage is that by setting pins and slots, this utility model also makes it easy to ensure that the mounting bracket is installed at the correct angle, avoiding the risk of tipping over if installed incorrectly.

[0053] Meanwhile, in some embodiments that use pins and sockets to achieve conductive connections, it helps the pins to be correctly inserted into the sockets, avoiding errors that could block current flow or signal transmission.

[0054] According to an embodiment of the present invention, in the mobile display device, the pin is located at the junction of the bottom wall and the inner wall of the mounting hole, and the slot is an opening at the bottom edge of the mounting bracket.

[0055] The advantages of this invention are: by setting the pin at the junction of the bottom wall and the inner wall of the mounting hole, the slot is the opening at the bottom edge of the mounting frame. On the one hand, this avoids forming a pin at the bottom of the mounting frame, reducing the risk of breakage. On the other hand, it makes full use of the interior of the mounting hole and the end of the mounting frame, rationally utilizes the existing structure, does not increase the space occupied, and does not affect the external layout.

[0056] According to an embodiment of the present invention, the mobile display device includes a housing assembly comprising a first bottom shell, the first bottom shell comprising a first mounting portion, the first mounting portion being provided with a mounting seat, the mounting seat being used to connect the mounting bracket, the first mounting portion comprising a boss, the mounting seat comprising a limiting groove matching the boss, one of the bottom of the limiting groove and the top surface of the boss being provided with a positioning pin, and the other of the bottom of the limiting groove and the top surface of the boss comprising a positioning hole for accommodating the positioning pin.

[0057] The advantages of this invention are: by setting a boss and a limiting groove, on the one hand, the first bottom shell has a boss, which can improve the strength of the first bottom shell and reduce deformation during the stress process; on the other hand, the first mounting part and the mounting seat are positioned and limited by the boss and the limiting groove, which reduces the possibility of the mounting seat tilting, tilting and offset relative to the first mounting part. At the same time, it also facilitates the assembly by using the cooperation of the boss and the limiting groove, reducing the risk of incorrect assembly.

[0058] At the same time, the first mounting part and the mounting base are arranged in a cross shape, which can support the mounting frame in multiple directions, reduce the risk of bending of the first mounting part and the mounting base, and effectively support and limit the mounting frame, reducing the occurrence of breakage and tipping.

[0059] Meanwhile, positioning pins and positioning holes are set on the boss and the limiting groove to limit the position of the mounting base, prevent the mounting base from shifting along the boss, and improve installation accuracy.

[0060] According to an embodiment of the present utility model, the mobile display device includes a mounting base with a wire hole, and the boss includes a through hole and a downwardly open wire groove. The wire hole, the through hole, and the wire groove are connected in sequence. The wire hole, the through hole, and the wire groove accommodate conductive lines, and the conductive lines electrically connect the second battery and the display.

[0061] The advantages are that by setting wire holes, wire channels and wire grooves, this utility model can also facilitate the concealment of conductive lines without affecting the external shape of the mobile display device, making the mobile display device look neat and beautiful.

[0062] Meanwhile, the boss can be formed into a groove through sheet metal processing, so that the first bottom shell is formed by stamping and bending a metal sheet, reducing manufacturing difficulty and cost.

[0063] According to an embodiment of the present invention, the mobile display device includes a housing assembly comprising a first bottom shell, the first bottom shell including a first opening for accommodating a second battery, the first opening including an upwardly curved edge.

[0064] The advantage of this invention is that by setting a first opening, the arrangement of the second battery is not affected, and the edge of the first bottom shell extends to the edge of the base, thereby improving the support capacity of the mounting bracket.

[0065] Meanwhile, the first opening has an upward-curved edge, which can enhance the strength of the middle part of the first bottom shell and meet mechanical requirements.

[0066] Meanwhile, the upward-curved edge of the first opening reduces the risk of damage caused by the first opening touching the second battery or the second bottom shell, thus protecting the second battery and the second bottom shell.

[0067] Meanwhile, the first opening has an upward-curved edge, which takes up less bottom space, allowing the first bottom shell and the second bottom shell to fit together, and the first bottom shell to support the second bottom shell, thereby improving the strength of the entire base.

[0068] Meanwhile, the first opening has an upward-curved edge, so the counterweight only needs to avoid it, making it easy to improve.

[0069] According to an embodiment of the present invention, the mobile display device includes a first bottom shell comprising a second mounting portion, the second mounting portion being a shell portion that is open downwards, the shell portion accommodating and mounting a traveling wheel, the traveling wheel being used for moving the mobile display device.

[0070] The advantage is that by setting a second mounting part, this utility model also allows the first bottom shell to be fitted with a traveling wheel, thus reducing the strength requirements of the second bottom shell.

[0071] This invention improves the strength of the first bottom shell by making the second mounting part an open shell facing downwards and by making the edge of the first bottom shell a three-dimensional structure, which is beneficial to improving the support stability.

[0072] This invention makes the mobile display device more aesthetically pleasing by making the second mounting part an open, downward-facing shell and hiding the wheels.

[0073] At the same time, it also makes the base have a smaller ground clearance, so that when a small angle of tilt occurs, other parts of the base can touch the ground, improving its ability to resist tipping.

[0074] According to an embodiment of the present invention, the mobile display device includes a configuration block comprising a second bottom shell disposed at the bottom of the first bottom shell, wherein the inner surface of the second bottom shell matches the outer surface of the first bottom shell.

[0075] The advantage of this invention is that by setting a second bottom shell, the first bottom shell forms the inner layer of the base, and the second bottom shell forms the outer layer of the base. This allows the first bottom shell to be used to meet the strength requirements, and the second bottom shell to be used to meet the requirements of arrangement and shape.

[0076] According to an embodiment of the present invention, the mobile display device includes a configuration block comprising a second bottom shell, the second bottom shell including a downwardly open mounting cavity for mounting the second battery, and the configuration block further including a first cover for covering the mounting cavity.

[0077] The advantages are that, by setting up an installation cavity and a first cover, this utility model also facilitates the installation and replacement of the second battery, making it convenient to use.

[0078] Meanwhile, the mounting cavity is open, so it does not affect the counterweight and the second speaker, and the workload of replacing the second battery is small.

[0079] At the same time, the first cover also makes it easy to cover the second battery, preventing external substances from entering and protecting the second battery.

[0080] According to an embodiment of the present invention, the second bottom shell of the mobile display device includes a downwardly open disassembly cavity for disassembling and assembling the base and the mounting bracket, and the configuration block further includes a second cover for covering the disassembly cavity.

[0081] The advantages are: by setting up a disassembly cavity and a second cover, this utility model also facilitates the assembly of the mounting bracket and the base.

[0099] The mobile display device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0100] Reference Figure 1 The present invention aims to provide an embodiment of a mobile display device.

[0101] In this embodiment, the mobile display device mainly includes a display 100, a base 110, and a mounting bracket 120 connecting the display 100 and the base 110.

[0102] The display 100 and the mounting bracket 120 are detachably connected, allowing the display 100 to be used either in combination with the mounting bracket 120 or independently, meeting the needs of different usage scenarios. The display 100 includes a display device and a first battery, while the base 110 includes a second battery 130. Both the first battery and the second battery 130 can power the display device.

[0103] First, this embodiment sets up a display 100, a base 110, and a mounting bracket 120. Therefore, by setting up the base 110, the display device can be moved freely to a suitable position for easy use, and the center of gravity can be kept low to prevent the display device from tipping over. By setting up the mounting bracket 120, the display 100 is also kept at a certain height to meet the display needs.

[0104] Secondly, in this embodiment, by setting up a display 100, the display 100 includes a display device and a first battery. Therefore, by setting up the first battery, when the display 100 is not connected to a socket, the first battery can supply power to the display device to meet temporary power needs. At the same time, it can also meet the usage needs in some cases where the base 110 and the mounting bracket 120 are not configured.

[0105] Furthermore, by providing a second battery 130 in this embodiment, the second battery 130 can supply power to the display device when the display 100 is not connected to the socket, thus meeting temporary usage needs.

[0106] Furthermore, by setting the second battery 130 in this embodiment, and placing the second battery 130 on the base 110, the capacity and size of the first battery can be reduced, which reduces the difficulty of setting the first battery on the display 100, helps the display 100 to maintain a smaller thickness, and reduces the impact on the shape of the display 100.

[0107] Meanwhile, by setting up a second battery 130 in this embodiment, the second battery 130 is located on the base 110, which not only meets the power needs, but also increases the weight of the base 110, thereby improving the stability of the mobile display device and preventing it from tipping over.

[0108] Furthermore, by setting up a second battery 130 in this embodiment, the second battery 130 is located in the base 110, which reduces the space restriction on the second battery 130. This allows the second battery 130 to be larger in size and weight, which can improve the stability of the mobile display device, increase the capacity of the second battery 130, reduce the dependence on power supply, improve portability, and meet the needs of various usage scenarios.

[0109] Furthermore, by setting the second battery 130 in this embodiment, the weight of the base 110 is increased and the ability to prevent tipping is improved. Therefore, the footprint of the base 110 can be appropriately reduced, thus reducing the footprint.

[0110] The specific configuration of the display device can be a liquid crystal display screen or an LED display screen, etc. Since this embodiment does not involve the improvement of the display principle, the specific composition of the display device is not described in detail, but this does not affect the clarity and completeness of the solution.

[0111] In some specific embodiments of this utility model, the display 100 can be equipped with a sound-emitting component, namely a first speaker, so that the display has a built-in sound-emitting function to meet the need for playing sound. Thus, it can provide both images and sound, satisfying multiple needs.

[0112] The first speaker is not shown in the illustration due to obstruction by external parts.

[0113] In some specific embodiments of this utility model, the mounting bracket 120 may include a liftable telescopic rod, and a motor, a screw and a screw sleeve may be configured inside the telescopic rod. Thus, driven by the motor, the screw rotates, thereby causing the screw sleeve to move up and down relative to the components, changing the height of the display 100 to meet the usage requirements.

[0114] In some specific embodiments of this utility model, the mounting bracket 120 may include a cross arm that connects to a telescopic rod. The cross arm connects to the display 100. Therefore, the telescopic rod can be connected to the edge of the base 110, and the end of the cross arm faces the center of the base 110. Thus, the display 100 is mounted above the center of the base 110, maintaining the stability of the mobile display device.

[0115] In some specific embodiments of this utility model, the display 100 and the cross arm can be connected through a universal ball joint structure, thereby changing the angle of the display 100 to meet display needs, such as tilting the display 100 upward or downward, or rotating the display 100 to the left or right, without requiring the base 110 to rotate together.

[0116] In some specific embodiments of this utility model, upper locking points and upper locking holes can be provided between the display 100 and the horizontal arm for installation and to prevent it from falling off.

[0117] In some specific embodiments of this utility model, a lower locking point and a lower locking hole can be provided between the display 100 and the cross arm. The lower locking point can elastically extend and retract relative to the upper locking point. Therefore, when the lower locking point is engaged in the lower locking hole, the bottom of the display 100 will not wobble, ensuring that the display 100 is stably installed on the mounting bracket 120. When the lower locking point rises, the display 100 can be swung to displace the lower locking point from the lower locking hole. Then, the display 100 can be lifted to separate the upper locking point from the upper locking hole, allowing the display 100 to be removed from the mounting bracket 120.

[0118] In some specific embodiments of this utility model, the mobile display device may include a connection detection structure, which is disposed between the mounting bracket 120 and the display 100, and is used to detect whether the display 100 and the mounting bracket 120 are connected.

[0119] It is easy to understand that this embodiment can determine the connection status between the display 100, the mounting bracket 120, and the base 110 by using a connection detection structure. Different switches are controlled according to the connection status, and different batteries are selected for power supply, thereby adaptively meeting the battery life performance of different usage scenarios and expanding the usage scenarios of mobile display devices.

[0120] That is, when the display 100 is connected to the mounting bracket 120, the display 100 can be powered by the second battery 130 of the base 110, or directly by mains power.

[0121] For example, the mobile display device can select the second battery 130 for power supply to meet display needs or to charge the first battery.

[0122] In some specific embodiments of this utility model, the connection detection structure may include a connector located on the display 100 and a detection pin located on the mounting bracket 120. After the connector contacts the detection pin, it generates a low-level positioning detection signal to confirm that the display 100 is connected to the mounting bracket 120.

[0123] Specifically, when the display 100 is correctly mounted on the mounting bracket 120, the connector and the detection pin make physical contact. This contact completes a circuit that allows current to flow from the connector to the detection pin, thereby generating a low-level position detection signal, indicating that the display 100 has been successfully connected to the mounting bracket 120.

[0124] In some specific embodiments of this utility model, the connection detection structure can be an electromagnetic induction structure. The electromagnetic induction structure includes a magnet located on the display 100 and a magnetic sensor located on the mounting bracket 120. The magnetic sensor is used to generate a low-level position detection signal when it detects that the magnetic field strength between the magnet and the magnetic sensor is greater than or equal to a preset field strength, so as to confirm that the display 100 is connected to the mounting bracket 120.

[0125] When the display 100 is brought close to the mounting bracket 120 and properly connected, the distance between the magnet and the magnetic sensor decreases, and the magnetic field strength detected by the magnetic sensor increases. The magnetic sensor then compares the detected magnetic field strength with a preset field strength.

[0126] This preset field strength is pre-set to determine whether the display 100 has been correctly connected to the mounting bracket 120. If the magnetic field strength detected by the magnetic sensor is greater than or equal to the preset field strength, it indicates that the display 100 has approached or contacted the appropriate position on the mounting bracket 120. At this time, the magnetic sensor determines that the display 100 and the mounting bracket 120 are connected and generates a low-level position detection signal.

[0127] It is understandable that if the display unit 100 is not connected to the bracket 400, neither the detection needle nor the magnetic sensor in the connection detection structure 300 can obtain the preset signal. At this time, the position detection signal is not grounded and is therefore at a high level.

[0128] Reference Figure 2 and Figure 7 In some specific embodiments of this utility model, the base 110 may also have a power connector 301 to connect to an external power source, so as to meet the needs of charging the first battery and the second battery 130 and the need to directly power the display 100.

[0129] Reference Figure 2In some specific embodiments of this utility model, the base 110 may include a second speaker 140, which is capable of communicating with the display 100 to play sound, and the second speaker 140 is disposed on top of the second battery 130.

[0130] It is easy to understand that by setting a second speaker 140 in this embodiment, which is located on the base 110, on the one hand, it is convenient to move the display device to play sound to meet the needs of audio-visual playback or presentation. On the other hand, a smaller second speaker 140 or even the second speaker 140 can be set on the display 100 to relieve the internal arrangement pressure of the display 100 and have less impact on the appearance of the display 100.

[0131] Furthermore, the second speaker 140 is located on the base 110, which reduces the restrictions on the second speaker 140 and makes it easier to upgrade the configuration and improve the sound quality.

[0132] Furthermore, the second speaker 140 is located on top of the second battery 130, which also facilitates increasing the diameter of the second speaker 140 so as to use a circular sound-emitting component, improve sound quality, and at the same time facilitate upward and forward sound transmission, ensuring that sound and image are consistently delivered to the audience, thus enhancing the user experience.

[0133] At the same time, the second speaker 140 can emit sound upwards, which is also conducive to transmitting sound directly and more effectively to the audience, so that the viewers of the display can have a good audio-visual experience.

[0134] Furthermore, the second speaker 140 is located on top of the second battery 130, which does not affect the horizontal dimensions of the second battery 130. This allows for the use of larger batteries with higher capacity, while also ensuring stability and reducing the risk of tipping over.

[0135] In some specific embodiments of this utility model, the second speaker 140 can be oriented to the left and right sides to meet diverse usage needs.

[0136] In some specific embodiments of this utility model, the number of second speakers 140 can be multiple. In this embodiment, there are two second speakers 140 arranged on the left and right sides, which facilitates the provision of multiple sound effects. Moreover, the central protrusion of the second speaker 140 can be offset from the top center of the second battery 130, thereby making the overlapping part of the second speaker 140 and the second battery 130 staggered, which is convenient for arrangement and does not increase the height of the base 110 too much.

[0137] Meanwhile, the second speaker is positioned around 140 degrees to balance hearing in both the left and right ears, enhancing the user experience.

[0138] In some specific embodiments of this utility model, the first speaker and the second speaker 140 can be high-voltage speakers or low-voltage speakers.

[0139] It is easy to understand that by making the first speaker and the second speaker 140 high-voltage speakers or low-frequency speakers, this embodiment can also change the sound quality to meet different usage needs, and thus be applied to different usage scenarios, such as home theaters, training meetings, etc.

[0140] In some specific embodiments of this utility model, the base 110 can be disc-shaped, which can not only meet the requirements of stable support, but also reduce the space occupied. Moreover, it has a balanced ability to pass through in all directions and can be moved at will.

[0141] Reference Figure 2 and Figure 3 In some specific embodiments of this utility model, the base 110 may include a counterweight 150, the bottom of the counterweight 150 is provided with a lower groove 151 for accommodating the second battery 130, and the top of the counterweight 150 is provided with an upper groove for accommodating the second speaker 140.

[0142] It is easy to understand that by setting the counterweight 150, the weight of the base 110 can be increased, thereby improving stability.

[0143] Meanwhile, the counterweight 150 is provided with an upper groove and a lower groove 151. On the one hand, this helps to reduce the height of the base 110, making the base 110 smaller in size. On the other hand, it also surrounds the second speaker 140 and the second battery 130, protecting the second speaker 140 and the second battery 130 and reducing the risk of damage to the second speaker 140 and the second battery 130.

[0144] Meanwhile, the addition of counterweight 150 also helps to maintain the shape of the base 110 and does not affect the design.

[0145] Reference Figure 2 and Figure 4 In some specific embodiments of this utility model, the base 110 may include a first bottom shell 160, the first bottom shell 160 includes a first mounting part, the first mounting part is provided with a mounting seat 170, the mounting seat 170 is used to connect the mounting frame 120, the mounting seat 170 includes an upper tube part 180 and a lower seat body 190, the upper tube part 180 is used to connect the mounting frame 120, and the lower seat body 190 is used to connect the first mounting part.

[0146] It is easy to understand that in this embodiment, by setting a first bottom shell 160, the first bottom shell 160 includes a first mounting part, and the first mounting part is provided with a mounting seat 170, which connects to the mounting frame 120. Therefore, the first bottom shell 160 can match the shape of the base 110 to meet the arrangement requirements without affecting the shape design of the base 110, making the design of the base 110 more diverse. At the same time, the first bottom shell 160 can improve the strength of the base 110 and reduce the bending and deformation of the base 110 to resist the overturning moment brought by the mounting frame 120 and the display 100, thereby stably supporting the mounting frame 120 and the display 100 to meet the usage requirements.

[0147] The mounting base 170 includes an upper tube 180 and a lower base 190. Therefore, the upper tube 180 can be used to connect the mounting bracket 120, simplifying assembly and disassembly. The lower base 190 can be used to connect the first bottom shell 160, which can improve the connection strength, so that the first bottom shell 160 and the lower base 190 can withstand the overturning moment and stably support the mounting bracket 120 and the display 100.

[0148] Moreover, the first base shell 160 and the mounting base 170 are mostly two independent components, which can reduce manufacturing difficulty, meet diverse needs, and facilitate disassembly and assembly, thereby reducing maintenance costs after damage.

[0149] In some specific embodiments of this utility model, the base 110 can include an integrally formed first bottom shell 160 and mounting base 170 to reduce the number of parts. However, the first bottom shell 160 and mounting base 170 have many integrated structures, and the impact on cost needs to be comprehensively considered. The impact on cost includes the impact on manufacturing cost and maintenance cost. The impact on maintenance cost includes the cost of spare parts and the time required for replacement.

[0150] Reference Figure 4 and Figure 5 In some specific embodiments of this utility model, the lower base 190 can have a length direction and a width direction. The length direction of the lower base 190 is set along the left and right direction of the mobile display device, and the width direction of the lower base 190 is set along the front and back direction of the mobile display device. The upper tube 180 is located in the direction away from the second battery 130 of the lower base 190.

[0151] It is easy to understand that by setting the length of the lower base 190 along the left and right direction of the mobile display device, this embodiment also avoids one end of the lower base 190 from facing the center of the base 110, thus not affecting the arrangement of the second battery 130, and allowing the second battery 130 to maintain a larger size.

[0152] It is easy to understand that this embodiment strengthens the support in the left and right directions by setting the width of the lower base 190 along the front and back direction of the mobile display device. That is, the two wide sides of the lower base 190 are located on the left and right sides of the mobile display device, thereby improving the stability of the mobile display device in the left and right directions and making it less likely to tip over.

[0153] It is easy to understand that by positioning the upper tube 180 in a direction away from the second battery 130 from the lower base 190, the mounting bracket 120 is connected to the edge of the base 110, thereby facilitating the placement of the display 100 at the center of the base 110, making the center of gravity of the mobile display device close to the center of the base 110, improving stability and preventing tipping.

[0154] In some specific embodiments of this utility model, at least one of the upper and lower wide sides of the lower base 190 may have a clearance groove 200, and the clearance groove 200 may be a dovetail groove.

[0155] It is easy to understand that by setting the clearance groove 200, the average thickness of the lower seat 190 can be reduced, which is beneficial to reduce material usage, and also facilitates the reduction of shrinkage during injection molding or casting, thereby improving the quality of the mounting seat 170.

[0156] Meanwhile, the clearance groove 200 is provided without reducing the solid volume of the four corners of the lower base 190, and without affecting the connection strength between the mounting base 170 and the first bottom shell 160.

[0157] Meanwhile, the recessed groove 200 reduces the obstruction of the first bottom shell 160, making the first bottom shell 160 more exposed, which facilitates the opening of holes for the placement of wires and components.

[0158] In some specific embodiments of this utility model, the upper and lower wide sides of the same side of the lower base 190 can be provided with clearance grooves 200, and the two clearance grooves 200 are not connected, which satisfies the clearance requirement and ensures the connection strength of the two corners of the lower base 190.

[0159] In some specific embodiments of this utility model, the mounting base 170 can be injection molded or cast, reducing processing and manufacturing costs.

[0160] In some specific embodiments of this utility model, the first bottom shell 160 can be made of stamped metal sheet, which can have a larger outer contour, thereby increasing the support area, improving the support capacity, and preventing the base 110 from bending and affecting the support of the display 100.

[0161] In some specific embodiments of this utility model, the mounting base 170 may include a mounting hole 210 for accommodating the bottom end of the mounting bracket 120, and the bottom wall of the mounting hole 210 is provided with mounting bolts 220 for connecting the mounting bracket 120 and the first mounting part.

[0162] It is easy to understand that, in this embodiment, by providing mounting holes 210, the bottom wall of which has mounting bolts 220, the bottom end of the mounting bracket 120 can be positioned using the mounting holes 210. That is, the bottom end of the mounting bracket 120 is inserted into the mounting holes 210, reducing the risk of the mounting bracket 120 tilting in any direction. At the same time, the mounting bolts 220 are used to connect the bottom end of the mounting bracket 120, so that the bottom end of the mounting bracket 120 is tightly attached to the bottom wall of the mounting holes 210, preventing the bottom end of the mounting bracket 120 from coming out of the mounting holes 210 and securing the mounting bracket 120 securely. At the same time, it prevents the inner surface of the mounting holes 210 from being overloaded and cracked. For example, if the bottom end of the mounting bracket 120 is inserted into the mounting holes 210 by a small section and tilts, the bottom end of the mounting bracket 120 may easily damage the hole wall of the mounting holes 210.

[0163] Meanwhile, in some embodiments that use pins and sockets to achieve conductive connections, the mounting bolts 220 ensure a tight connection between the mounting base 170 and the mounting bracket 120, which also helps to keep the pins inserted into the sockets, improving the reliability of current flow and signal transmission.

[0164] The mounting bolts 220 connect the first mounting part and the mounting bracket 120, and also fasten the first bottom shell 160, the mounting base 170 and the mounting bracket 120 together, so that the first bottom shell 160, the mounting base 170 and the mounting bracket 120 are a whole, so that the first bottom shell 160 can be used to resist the overturning moment, maintain the stability and strength of the mobile display device, and prevent it from tipping over and bending.

[0165] Mounting bolts 220 are used to connect mounting bracket 120 and first mounting part, and can also connect and fix second bottom shell 380 together to reduce the number of screws, simplify installation, and at the same time meet the needs of installation fastening.

[0166] In some specific embodiments of this utility model, the mounting hole 210 can be the inner surface of the upper tube 180, which reduces the molding difficulty and simplifies the shape of the mounting bracket 120.

[0167] In some specific embodiments of this utility model, the mounting hole 210 can be a shape other than a round hole, so that the fit between the mounting hole 210 and the mounting bracket 120 has obvious directional requirements, avoiding the mounting bracket 120 being forcibly inserted into the mounting hole 210 and avoiding incorrect installation. In particular, the operation of inserting the mounting bracket 120 into the mounting hole 210 will also cause the wiring connection.

[0168] In some specific embodiments of this utility model, one of the mounting base 170 and the mounting bracket 120 may include a pin 230, and the other of the mounting base 170 and the mounting bracket 120 may include a slot 231 for receiving the pin 230. The pin 230 and the slot 231 cooperate to determine the mounting angle of the mounting bracket 120 relative to the mounting hole 210.

[0169] It is easy to understand that by setting the pin 230 and the slot 231, this embodiment also facilitates ensuring that the mounting bracket 120 is installed at the correct angle, and avoids the risk of tipping over if installed incorrectly.

[0170] Meanwhile, in some embodiments that use pins and sockets to achieve conductive connections, it helps the pins to be correctly inserted into the sockets, avoiding errors that could block current flow or signal transmission. At the same time, the mounting bracket 120 can be used to couple and decouple the circuit, simplifying the wiring connection.

[0171] In some specific embodiments of this utility model, the pin 230 and the slot 231 can be additional structures that are easy to observe, but this may make the structure of the base 110 and the mounting bracket 120 less simple and compact, and adjustments need to be made according to the actual situation.

[0172] In some specific embodiments of this utility model, the pin 230 can be located at the junction of the bottom wall and the inner wall of the mounting hole 210, and the slot 231 is the opening at the edge of the bottom end of the mounting bracket 120.

[0173] It is easy to understand that in this embodiment, by setting the pin 230 at the junction of the bottom wall and the inner wall of the mounting hole 210, the slot 231 is an opening at the bottom edge of the mounting bracket 120. On the one hand, this avoids forming the pin 230 at the bottom of the mounting bracket 120, reducing the risk of breakage. On the other hand, it makes full use of the interior of the mounting hole 210 and the end of the mounting bracket 120, making reasonable use of the existing structure without increasing the space occupied or affecting the external layout.

[0174] Reference Figure 4 to Figure 6 In some specific embodiments of this utility model, the first mounting part may include a boss 240, the mounting base 170 may include a limiting groove 250 that matches the boss 240, one of the bottom of the limiting groove 250 and the top surface of the boss 240 may be provided with a positioning pin 261, and the other of the bottom of the limiting groove 250 and the top surface of the boss 240 may include a positioning hole 260 for accommodating the positioning pin 261.

[0175] It is easy to understand that by setting the boss 240 and the limiting groove 250 in this embodiment, on the one hand, the first bottom shell 160 has the boss 240, which can improve the strength of the first bottom shell 160 and reduce deformation during the stress process. On the other hand, the first mounting part and the mounting base 170 are positioned and limited by the boss 240 and the limiting groove 250, which reduces the possibility of the mounting base 170 tilting, tilting and offset relative to the first mounting part. At the same time, it also facilitates the assembly by using the cooperation of the boss 240 and the limiting groove 250, reducing the risk of incorrect assembly.

[0176] At the same time, the first mounting part and the mounting base 170 are arranged in a cross shape, which can support the mounting frame 120 in multiple directions, reduce the risk of bending of the first mounting part and the mounting base 170, and effectively support and limit the mounting frame 120, reducing the occurrence of breakage and tipping.

[0177] Meanwhile, positioning pins 261 and positioning holes 260 are provided on the boss 240 and the limiting groove 250 to limit the position of the mounting base 170, thereby preventing the mounting base 170 from shifting along the boss 240 and improving installation accuracy.

[0178] In some specific embodiments of this utility model, the mounting base 170 may include a wire hole 270, and the boss 240 may include a wire through hole 280 and a downwardly open wire groove 290. The wire through hole 270, the wire through hole 280 and the wire groove 290 are connected in sequence. The wire through hole 270, the wire through hole 280 and the wire groove 290 accommodate a conductive line 300, and the conductive line 300 electrically connects the second battery 130 and the display 100.

[0179] It is easy to understand that by setting the wire through hole 270, the wire through hole 280 and the wire groove 290, this embodiment can also conveniently hide the conductive line 300 without affecting the external shape of the mobile display device, making the mobile display device look neat and beautiful.

[0180] Meanwhile, the boss 240 can be formed into the groove 290 through sheet metal processing, so that the first bottom shell 160 is formed by stamping and bending a metal plate, reducing manufacturing difficulty and manufacturing cost.

[0181] In some specific embodiments of this utility model, the cross-sectional profile of the wire hole 270 can be rectangular to facilitate the passage of more and thicker wires.

[0182] In some specific embodiments of this utility model, the mounting base 170 can be provided with process holes, and both the process holes and the wire passage holes 270 are arranged at the bottom of the limiting groove 250, further reducing the thickness of the mounting base 170.

[0183] In some specific embodiments of this utility model, the process hole and the wire hole 270 can be connected to change the wiring path and meet various wiring needs.

[0184] In some specific embodiments of this utility model, the first bottom shell 160 may include a first opening 310 for accommodating the second battery 130, and the first opening 310 may include an upwardly curved edge 320.

[0185] It is easy to understand that by setting the first opening 310, this embodiment not only does not affect the arrangement of the second battery 130, but also allows the edge of the first bottom shell 160 to extend to the edge of the base 110, thereby improving the ability to support the mounting bracket 120.

[0186] Meanwhile, the first opening 310 has an upward-curving edge 320, which can enhance the strength of the middle part of the first bottom shell 160 and meet mechanical requirements.

[0187] Meanwhile, the first opening 310 has an upward-curved edge 320, which reduces the damage caused by the first opening 310 touching the second battery 130 or the second bottom shell 380, and protects the second battery 130 and the second bottom shell 380.

[0188] Meanwhile, the first opening 310 has an upward-curved edge 320, which occupies less bottom space, allowing the first bottom shell 160 and the second bottom shell 380 to fit together. The first bottom shell 160 can support the second bottom shell 380, thereby improving the strength of the entire base 110.

[0189] Meanwhile, the first opening 310 has an upward-curving edge 320, which the counterweight 150 only needs to avoid, making the improvement easy.

[0190] In some specific embodiments of this utility model, the wire groove 290 can be connected to the inside of the first opening 310 to facilitate the connection of the wire to the second battery 130.

[0191] In some specific embodiments of this utility model, the first bottom shell 160 may include a second mounting portion, which is a shell portion 330 that is open downwards. The shell portion 330 accommodates and mounts a traveling wheel 381, which is used to move the display device.

[0192] It is easy to understand that by providing a second mounting part, this embodiment also enables the first bottom shell 160 to be fitted with a traveling wheel 381, thereby reducing the strength requirements of the second bottom shell 380.

[0193] It is easy to understand that by making the second mounting part a downward-open shell 330 and making the edge of the first bottom shell 160 a three-dimensional structure, the strength of the first bottom shell 160 is improved, which is beneficial to improving the support stability.

[0194] It is easy to understand that by making the second mounting part a downward-open shell 330, this embodiment also hides the wheels 381, making the mobile display device more aesthetically pleasing.

[0195] At the same time, it also makes the ground clearance of the base 110 smaller, so that when a small angle of tilt occurs, other parts of the base 110 can touch the ground, improving the ability to resist tipping.

[0196] Reference Figure 7 In some specific embodiments of this utility model, the base 110 may include a second bottom shell 380, which is disposed at the bottom of the first bottom shell 160, and the inner surface of the second bottom shell 380 matches the outer surface of the first bottom shell 160.

[0197] It is easy to understand that by setting a second bottom shell 380 in this embodiment, the first bottom shell 160 forms the inner layer of the base 110, and the second bottom shell 380 forms the outer layer of the base 110. This allows the first bottom shell 160 to meet the strength requirements, and the second bottom shell 380 to meet the requirements for arrangement and shape.

[0198] The inner surface of the second bottom shell 380 matches the outer surface of the first bottom shell 160. This means that the inner surface of the second bottom shell 380 and the outer surface of the first bottom shell 160 are generally in contact to improve strength. In some cases where it is necessary to arrange wires, one or both of the first bottom shell 160 and the second bottom shell 380 can be used to form a wiring channel to simplify the wiring layout.

[0199] In some specific embodiments of this utility model, the second bottom shell 380 can be made to protrude upward into the recess of the first bottom shell 160, thereby forming the inner layer of the wire groove 290 by the second bottom shell 380, which facilitates the connection of the conductive line 300 to the second battery 130. Therefore, the number of holes opened on the second bottom shell 380 can be reduced, which is convenient for manufacturing.

[0200] In some specific embodiments of this utility model, the second bottom shell 380 can be made to protrude upward into the recess of the first bottom shell 160, thereby forming the inner layer of the shell portion 330 by the second bottom shell 380, which facilitates the installation of the walking wheel 381 and also helps to shield and reduce the risk of dust entering the base 110.

[0201] In some specific embodiments of this utility model, the second bottom shell 380 and the first bottom shell 160 can be connected by screws, so that the second bottom shell 380 and the first bottom shell 160 form a composite part, which has high strength, is convenient for installing various components, and has low manufacturing cost.

[0202] In some specific embodiments of this utility model, the second bottom shell 380, the first bottom shell 160 and the mounting bracket 12 can be connected by mounting bolts 220 to simplify assembly and make the base 110 structure more compact.

[0203] Reference Figure 7 and Figure 8 In some specific embodiments of this utility model, the second bottom shell 380 may include a downwardly open mounting cavity 340 for mounting the second battery 130, and the base 110 may also include a first cover 350 for covering the mounting cavity 340.

[0204] It is easy to understand that, by providing the mounting cavity 340 and the first cover 350, this embodiment also facilitates the installation and replacement of the second battery 130, making it convenient to use.

[0205] Meanwhile, the mounting cavity 340 is open, which does not affect the counterweight 150 and the second speaker 140, and the workload of replacing the second battery 130 is small.

[0206] Meanwhile, the first cover 350 also facilitates the covering of the second battery 130, preventing external substances from entering and protecting the second battery 130.

[0207] In some specific embodiments of this utility model, the second bottom shell 380 may include a downwardly open disassembly cavity 360, which is used for disassembling and assembling the base 110 and the mounting bracket 120. The base 110 may also include a second cover 370 for covering the disassembly cavity 360.

[0208] It is easy to understand that by setting up the disassembly cavity 360 and the second cover 370, this embodiment also facilitates the assembly of the mounting bracket 120 and the base 110. At the same time, the disassembly and assembly from the bottom of the base 110 also makes the transition between the bottom of the mounting bracket 120 and the top of the base 110 smooth, without exposing screws, etc., and does not affect the shape and texture of the mobile display device.

[0209] In some specific embodiments of this utility model, wire clips can be arranged inside the disassembly cavity 360 to facilitate the fixing of the conductive line 300.

[0210] For the installation of the first cover 350 and the second cover 370, the first cover 350 can have a buckle 351 on one side and a snap fastener on the other side. First, insert the buckle 351 into the opening on the second bottom shell 380, and then rotate the first cover 350 so that the snap fastener is engaged with the second bottom shell 380 to complete the installation and reduce the number of screws.

[0211] Correspondingly, the second cover 370 can be set with reference to the first cover 350. At the same time, since the first cover 350 is to enclose the second battery 130 in the mounting cavity 340, the first cover 350 can be equipped with screws to prevent the first cover 350 from falling off.

[0212] In some specific embodiments of this utility model, the second bottom shell 380 can be provided with a hole that matches the buckle 351 or the snap fastener. This hole can be formed by the top contact of the cavity and the punch in the injection mold, making the hole easy to form and reducing the manufacturing difficulty.

[0213] Meanwhile, the buckle 351 can also protrude outward from the first cover 350 in a direction parallel to the first cover 350, which not only meets the installation requirements, but also facilitates the manufacturing process of injection molding, and simplifies the structure of the injection mold.

[0214] Reference Figure 1 In some specific embodiments of this utility model, the base 110 may also include a cover that covers the second bottom shell 380.

[0215] It is easy to understand that, in this embodiment, by setting a cover, the second speaker 140, the counterweight 150, etc. are also covered, so that the base 110 has a good shape and improves the user experience.
