Description

Technical Field

[0001] The present application relates to the technical field of handheld device display stands, and in particular to a display stand for handheld devices. Background Art

[0002] In daily life, handheld appliances such as electric toothbrushes and shavers can usually be placed upright on a desktop. In order to facilitate charging of these handheld appliances, the prior art proposes a technical solution for matching handheld appliances with a charging base. For example, in the patent document entitled "Personal Care Product Docking System" with the authorization announcement number CN110191660B, a wireless charging system 148 is provided in the bracket 150; for another example, in the patent document entitled "An Electric Toothbrush Charging Device and Electric Toothbrush Assembly" with the authorization announcement number CN217448094U, a charging component can be provided in the base shell 1, and the charging component can be a wireless charging coil, a contact charging component or a charging interface. However, if the base of the prior art is directly applied to the display scene of the handheld appliance, such as an exhibition counter or a supermarket shelf, it is difficult to obtain a better display effect, because: the height of the base of the prior art is small and is directly placed on the external support surface, so the emitted light of the external support surface is easily projected onto the displayed handheld appliance, or other objects on the external support surface are easy to block the handheld appliance.

[0059] DETAILED DESCRIPTION

[0060] 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 described embodiments 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 ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] Reference Figures 1 to 4 as well as Figures 13 to 16 In one embodiment, the display stand 100 for holding a device proposed in the present application includes:

[0062] The base 10 includes a housing 11 and a main circuit board 30 disposed in the housing 11;

[0063] The stand 40 includes a support frame 41, an electrical transmission device 56 and an electrical connection line (not shown); wherein,

[0064] The support frame 41 includes a support rod 42 and a support head 44; the support rod 42 extends in the up-down direction and is in a long strip shape, and a wiring channel 43 is formed inside, and the lower end is connected to the housing 11; the support head 44 is connected to the upper end of the support rod 42, and the support head 44 is provided with an upper attachment surface 45 for supporting the lower end of the handheld device 200, and the upper attachment surface 45 protrudes from the outer peripheral surface of the support rod 42;

[0065] The electric transmission device 56 is disposed on the support head 44 for electrically coupling with the electric receiving device 210 of the handheld device 200 ; the electric connection wire is disposed in the wiring channel 43 and is electrically connected to the main circuit board 30 and the electric transmission device 56 respectively.

[0066] In this embodiment, the base 10 is used to provide support and protection. For example, compared with the stand 40, the base 10 is larger in size and can provide a sufficiently large support surface. The base 10 can provide protection for the main circuit board 30 when providing a space for accommodating the main circuit board 30. The main circuit board 30 is used to process electrical energy and electrical signals after connecting to a power source. In order to reduce the obstruction of vision, the cross-sectional dimension of the support rod 42 is much smaller than the length dimension of the support rod 42. The support head 44 is used to form a sufficiently large upper attachment surface 45 and is used to install the electric transmission device 56. Since the wiring channel 43 is formed inside the support rod 42, it can simultaneously prevent the electrical connection line from affecting the display effect of the handheld device 200. In a preferred embodiment, the support rod 42 is made of stainless steel, and the support head 44 is an injection molded part. The electric transmission device 56 can be a wireless charging coil, a contact charging component or a charging interface. The handheld device 200 can be a personal care appliance such as an electric toothbrush and a shaver.

[0067] The display stand 100 of the handheld device 200 of the utility model is provided with a stand 40, and the stand 40 has a long strip-shaped support rod 42 extending in the up-down direction, and the support head 44 for supporting the lower end of the handheld device 200 is connected to the upper end of the support rod 42, so that the handheld device 200 displayed receives less light interference from the external support surface, and is not easily blocked by other objects. Since the attachment surface of the support head 44 protrudes from the outer peripheral surface of the support rod 42, the support area can be increased to ensure that the handheld device 200 is firmly supported. In addition, since the wiring channel 43 is provided inside the support rod 42, not only the support height can be increased, but also during the display of the handheld device 200, the main circuit board 30 can supply power to the power receiving device 210 of the handheld device 200 through the electrical connection line and the electrical transmission device 56, so that the handheld device 200 can still maintain sufficient power during the long-term display process.

[0068] Further, please refer to Figure 5 , Figure 6 , Figures 8 to 12 , Fig.17 as well as Fig.19 The base 10 also includes a first electrical connector 31 electrically connected to the main circuit board 30; the support frame 41 also includes a second electrical connector 48 electrically connected to the lower end of the electrical connection line, and the lower end of the support rod 42 is detachably connected to the shell 11. After the lower end of the support rod 42 is connected to the shell 11, the electrical connection line is electrically connected to the main circuit board 30 through the electrical connection between the second electrical connector 48 and the second electrical connector 48.

[0069] In this embodiment, since the support rod 42 is detachably connected to the shell 11, the stand 40 of different heights can be easily replaced to suit the display of different types of handheld nursing appliances.

[0070] Furthermore, an embedding groove 12 is provided on the shell 11, and the support frame 41 also includes a support seat 49 connected to the lower end of the support rod 42, the support seat 49 has a lower attachment surface 50 that matches the inner surface of the embedding groove 12, and the lower attachment surface 50 protrudes from the outer peripheral surface of the support rod 42. The second electrical connector 48 is provided on the support seat 49, and the lower end of the support rod 42 is detachably connected to the shell 11 through the support seat 49.

[0071] In this embodiment, the stand 40 is embedded in the groove 12 through the support seat 49 to achieve a detachable connection. Since the lower attachment surface 50 protrudes from the outer peripheral surface of the support rod 42, the support force arm can be expanded to achieve better stability.

[0072] Furthermore, in order to enhance the stability of the stand 40, the support frame 41 also includes a first magnetic component 54 disposed on the lower surface of the support seat 49, and the base 10 also includes a second magnetic component 34 disposed adjacent to the bottom wall of the embedding groove 12, and the second magnetic component 34 is magnetically coupled with the first magnetic component 54.

[0073] Furthermore, a lower fixing hole 51 penetrating through the bottom surface is formed on the top surface of the support seat 49, the lower end of the support rod 42 is fixedly connected to the upper portion of the lower fixing hole 51, and the second electrical connector 48 is fixedly arranged at the lower portion of the lower fixing hole 51; one of the first electrical connector 31 and the second electrical connector 48 is provided with a spring pin, and the other is provided with an electrical contact pad adapted to the spring pin.

[0074] In this embodiment, the lower end of the support rod 42 and the second connector are both arranged in the lower fixing hole 51, so that the structure of the support seat 49 and the assembly of the support seat 49 can be simplified, and the electrical connection between the electrical connection line and the second electrical contactor can be facilitated. The spring pin cooperates with the electrical contact point to achieve electrical connection, which can avoid the plug-in and pull-out force of the interface connection and keep the relevant surface flat. The magnetic attraction cooperation of the first magnetic attraction member 54 and the second magnetic attraction member 34 can provide appropriate electrical contact pressure for the cooperation between the spring pin and the electrical contact point.

[0075] Furthermore, the bottom surface of the support seat 49 is provided with an annular lower mounting groove 52 at the periphery of the lower fixing hole 51 , and the first magnetic attraction member 54 is fixedly disposed in the lower mounting groove 52 and is in an annular shape adapted to the lower mounting groove 52 .

[0076] In this embodiment, the first magnetic attraction member 54 is annular and fixedly disposed in the lower mounting groove 52, which can not only provide uniform magnetic attraction force but also achieve better limiting to prevent falling off or displacement.

[0077] Furthermore, the base 10 is flat, and the thickness direction is consistent with the vertical direction; the shell 11 includes a chassis 13, an upper cover 21 and a limit seat 24, the chassis 13 is open upward, the upper cover 21 covers the upper opening of the chassis 13, the limit seat 24 is located between the upper cover 21 and the chassis 13, and the limit seat 24 is fixedly connected to the chassis 13; the embedding groove 12 includes a plug-in hole 22 opened on the upper cover 21, and a limit groove 25 formed on the limit seat 24.

[0078] In this embodiment, the housing 11 includes a separate chassis 13, an upper cover 21 and a limit seat 24, which can be easily formed according to its own structural characteristics and can also facilitate the installation of components such as the main circuit board 30.

[0079] Furthermore, the limit seat 24 includes a mounting plate 26 and a limit ring 27 protruding from the upper surface of the mounting plate 26, and the limit groove 25 is formed in the inner cavity of the limit ring 27; the mounting plate 26 is provided with an electrical connection hole 261 on the inner side of the limit ring 27, and the first electrical connector 31 is exposed to the embedding groove 12 through the electrical connection hole 261.

[0080] In this embodiment, the limiting groove 25 is formed in the inner cavity of the limiting ring 27, so that while stably supporting the stand 40, it can save materials because the mounting plate 26 and the limiting ring 27 are both thin-walled structures. The first electrical connector 31 is arranged on the bottom wall of the limiting groove 25, so that the gravity of the handheld device 200 and the stand 40 can also be used to provide appropriate electrical contact pressure for the cooperation between the spring pin and the electrical contact point.

[0081] Furthermore, the mounting plate 26 is provided with a plurality of first through holes 262 on the periphery of the limiting ring 27, and the inner side surface of the base 10 is provided with a first screw hole column 14 corresponding to each first through hole 262; the first electrical connector 31 includes a lower circuit board 32 and an electrical contact seat 33, the lower circuit board 32 is electrically connected to the main circuit board 30 and is clamped between the mounting plate 26 and the chassis 13, and the electrical contact seat 33 is fixed on the upper surface of the lower circuit board 32 and is located in the electrical connection hole 261.

[0082] In this embodiment, the mounting base can be detachably fixed to the base 10 by means of screws. Specifically, the screw passes through the first through hole 262 and is threadedly connected to the threaded hole of the first screw hole column 14. Since the lower circuit board 32 of the first electrical connector 31 is located between the mounting plate 26 and the chassis 13, the first electrical connector 31 can be fixed together with the mounting base.

[0083] Furthermore, the limit seat 24 also includes a limit cylinder 28 protruding from the lower surface of the mounting plate 26, the limit cylinder 28 is arranged corresponding to the first through hole 262 and the inner cavity is connected to the first through hole 262; the lower end surface of the limit cylinder 28 abuts against the upper surface of the lower circuit board 32; the lower circuit board 32 corresponds to the first screw hole column 14 and is provided with a second through hole 321 connected to the inner cavity of the limit cylinder 28, and the lower surface of the lower circuit board 32 abuts against the upper end surface of the first screw hole column 14.

[0084] In this embodiment, the limit cylinder 28 can maintain the distance between the lower circuit board 32 and the mounting plate 26, and the first screw hole column 14 can maintain the distance between the lower circuit board 32 and the inner side of the base 10, thereby better protecting the components on the lower circuit board 32 while achieving the fixation of the limit seat 24 and the first electrical connector 31.

[0085] Furthermore, the lower surface support frame 41 of the support seat 49 also includes a first magnetic component 54 arranged on the lower surface of the support seat 49, the limit seat 24 also includes a mounting ring 29 protruding from the lower surface of the mounting plate 26, and the base 10 also includes a second magnetic component 34 embedded in the inner side of the mounting ring 29, and the second magnetic component 34 is magnetically matched with the first magnetic component 54.

[0086] In this embodiment, the second magnetic member 34 is installed on the inner side of the mounting ring 29 , which not only can achieve a stable installation, but also can fully utilize the space between the mounting plate 26 and the lower circuit board 32 .

[0087] Furthermore, in order to keep the stand 40 in a preset position after assembly, the inner circumference of the limiting groove 25 is formed with a circumferential limiting surface 251 , and the outer circumference of the support seat 49 has an anti-mistake surface 53 that fits with the circumferential limiting surface 251 .

[0088] Further, in order to prevent the displayed handheld device 200 from being stolen, refer to Figures 4 to 12 In one embodiment, the base 10 includes a chassis 13 and an upper cover 21; the chassis 13 is open upward, the upper cover 21 covers the upper opening of the chassis 13, and the upper cover 21 is provided with an external lead hole 23; the base 10 also includes an anti-theft device 35 located between the upper cover 21 and the chassis 13, the anti-theft device 35 includes a winding box 36 and an anti-theft rope that can be wound in the winding box 36, the winding box 36 is fixedly connected to the chassis 13 or the upper cover 21, the anti-theft rope is passed through the external lead hole 23 and is fixedly connected to the handheld device 200.

[0089] Further, it is understandable that the upper cover 21 and the base 10 can clamp the winding box 36 after being fixed, that is, the winding box 36 is limited in the vertical direction. In order to achieve better lateral limitation, the inner side of the chassis 13 is provided with a mounting cylinder 15, and the winding box 36 is located in the mounting cylinder 15.

[0090] Further, it can be understood that when the anti-theft rope is pulled, the winding box 36 will be subjected to a torque force, the upper edge of the mounting tube 15 is provided with a limiting notch 16, the winding box 36 is in a flat columnar shape, and the outer peripheral surface of the winding box 36 is provided with a limiting boss 37 adapted to the limiting notch 16, so that the winding box 36 can be prevented from rotating.

[0091] Furthermore, the outer end surface of the limiting boss 37 is provided with an inner lead hole 371 communicating with the inner cavity of the winding box 36, and the anti-theft rope is sequentially passed through the inner lead hole 371 and the outer lead hole 23 and fixedly connected to the handheld device 200. The inner limiting hole is provided on the limiting boss 37 to partially increase the strength of the inner lead hole 371 and to make the structure of the mounting tube 15 and the anti-theft device 35 simpler.

[0092] Furthermore, the upper cover 21 includes a main body 17 and a guide shoe 18. The main body 17 covers the upper opening of the chassis 13. The main body 17 is provided with a pre-assembly hole 171. The guide shoe 18 is cylindrical and penetrates from top to bottom. The guide shoe 18 is fixedly arranged in the pre-assembly hole 171. The external lead hole 23 is formed in the guide shoe 18. The hardness of the guide shoe 18 is greater than the hardness of the main body 17, and the friction coefficient of the guide shoe 18 is smaller than the friction coefficient of the main body 17.

[0093] Furthermore, a step surface is provided on the lower edge of the upper cover 21, and the upper cover 21 covers the upper opening of the chassis 13 through the step surface. The periphery of the upper cover 21 is flush with the periphery of the chassis 13, so that a gap at the connection between the upper cover 21 and the chassis 13 can be formed on the side of the base 10, making the gap difficult to be observed, thereby improving the aesthetics of the base 10.

[0094] In this embodiment, the guide shoe 18 can partially increase the strength of the outer lead hole 23 to prevent excessive damage to the outer lead hole 23 during repeated winding and releasing of the anti-theft rope, and at the same time can reduce the friction during the winding and releasing of the anti-theft rope.

In this way, the stability of the handheld device 200 can be increased, and the electrical coupling between the electric transmission device 56 and the point receiving device can be made more reliable, because the magnetic attraction can provide appropriate contact pressure for the electrical contact.

[0104] Furthermore, the third magnetic member 55 is annular and surrounds the electric transmission device 56, and the inner side surface of the top wall of the support cylinder 46 is provided with an upper mounting groove 462 adapted to the third magnetic member 55. In this embodiment, the annular third magnetic member 55 can provide a more uniform magnetic attraction, and can be prevented from loosening or shifting by being embedded in the upper mounting groove 462.
