Detailed implementation mode

[0044] To make the objectives, features, and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Embodiment 1

[0046] Please refer to Figure 1 As shown, this embodiment provides a mobile workbench, which includes a brake mechanism 600. The brake mechanism 600 includes a fixed pipe 170. The fixed pipe 170 is connected to a first connecting pipe 300, and the first connecting pipe 300 is connected to a second connecting pipe 400.

[0047] The fixed pipe 170 and the first connecting pipe 300, and the first connecting pipe 300 and the second connecting pipe 400 are detachably connected through a quick-release structure 500, enabling the mobile workbench to be quickly assembled and disassembled.

[0048] To meet the working needs, a first device set and a second device set are usually provided on the first connecting pipe 300 and the second connecting pipe 400 respectively. The power supply for the first device set and the second device set is taken from the power line 202.

[0049] As an alternative, the first device set includes a workbench surface 303 fixed by a fixed support frame 304. The first device set also includes a control host 301, a display screen 302, and a serial interface 305. As a specific application scenario, the storage items on the workbench surface 303 are scanned by a scanner, the control host 301 saves the data of the storage items, the display screen 302 is used to display the scanning information, and the serial interface 305 is used to connect to an external memory, etc.

[0050] As an alternative, the second device set includes an LED lamp 401 and a camera 402. As a specific application scenario, the LED lamp 401 can provide illumination for the workbench surface 303, and the camera 402 is connected to the control host 301 and can be used to unlock the control host 301 after face recognition.

[0051] It should be noted that, according to needs, multiple connecting pipes can be freely connected and matched through the quick-release structure 500, and more functions can be realized for the mobile workbench through the device sets arranged on the connecting pipes.

[0052] Specifically, wheels 130 are provided at the bottom of the braking mechanism 600, and the mobile workbench moves by rolling of the wheels 130.

[0053] Embodiment 2

[0054] Please refer to Figure 2 As shown, on the basis of Embodiment 1, the structure of the braking mechanism 600 is specifically disclosed in this embodiment. The braking mechanism 600 includes a driving component 110 and a telescopic rod 100. The telescopic rod 100 is driven by the driving component 110 to stretch and touch or not touch the ground, so as to use the friction generated by the telescopic rod 100 touching the ground for braking.

[0055] As an alternative in this embodiment, the driving component 110 can be an electric push rod, and the telescopic rod 100 is pushed by the electric push rod to achieve braking.

[0056] Please refer to Figure 3 As shown, as another alternative in this embodiment, the driving component 110 includes a sleeve 113. The inside of the sleeve 113 is hollow, an elastic element 112 is provided inside the sleeve 113, and the inner wall of the sleeve 113 is also slidably connected to the telescopic rod 100. A direct traction member 111 passes through the top of the sleeve 113 and the elastic element 112. One end of the direct traction member 111 is connected to the telescopic rod 100, and the other end is connected to a brake handle 140 or a motor. Optionally, the elastic element 112 is a spring.

[0057] Therefore, by means of the motor or the brake handle 140, the direct traction member 111 can be driven to pull up the telescopic rod 100, so that the telescopic rod 100 slides within the sleeve 113, and the elastic element 112 is compressed within the sleeve 113. At this time, the telescopic rod 100 gradually leaves the ground, achieving non-braking. When the brake handle 140 is released, under the action of the elastic element 112, the telescopic rod 100 extends out of the sleeve 113 until it touches the ground and generates the frictional force for braking. Thus, it can be seen that the elastic element 112 is always in a compressed state to generate a thrust force on the telescopic rod 100.

[0058] In order to improve the braking effect, a foot pad 101 for increasing the frictional force is provided at the bottom of the telescopic rod 100.

[0059] In order to prevent the telescopic rod 100 from sliding out of the sleeve 113, a stepped boss 102 is provided on the outer wall of the telescopic rod 100, and a limiting member 114 for blocking the boss 102 is installed on the sleeve 113. Optionally, the limiting member 114 is a screw, and by blocking the boss 102 with the screw, the extension length of the telescopic rod 100 can also be limited.

[0060] The mobile workbench provided in this embodiment drives the telescopic rod 100 to touch the ground to generate frictional force through the driving assembly 110, and uses this frictional force to achieve braking, solving the problem that the prior art cannot brake, and the braking mechanism 600 has a simple structure and is easy to implement.

[0061] Furthermore, in order to protect the components inside the braking mechanism 600 and beautify the appearance, an outer cover 201 is provided outside the braking mechanism 600.

[0062] Embodiment Three

[0063] Please refer to Figure 2 and 4 As shown, on the basis of Embodiment Two, the braking mechanism 600 further includes a fixing plate 120, and a plurality of sleeves 113 are provided on the fixing plate 120. Each sleeve 113 corresponds to a telescopic rod 100, so there are a plurality of direct traction members 111.

[0064] In order to be able to synchronously control a plurality of direct traction members 111, a guiding seat 151 is arranged in the middle of the fixing plate 120. A plurality of guiding holes 152 for passing through the direct traction members 111 are provided on the guiding seat 151, and all the direct traction members 111 are commonly connected to a lifting block 153 after passing through the guiding holes 152.

[0065] Therefore, the brake handle 140 realizes synchronous control of all the direct traction members 111 by controlling the lifting of the lifting block 153, thereby controlling the telescopic rods 100 to brake or not brake synchronously.

[0066] Embodiment Four

[0067] Please refer to Figure 2 and 4 As shown, on the basis of Embodiment III, the braking mechanism 600 further includes an integrated pulley assembly 150. The integrated pulley assembly 150 includes a coaxial first pulley 154 and a second pulley 155. The radii of the first pulley 154 and the second pulley 155 are not equal. The first pulley 154 is connected to the brake handle 140 through a first indirect traction member 161, and the second pulley 155 is connected to the lifting block 153 through a second indirect traction member 162. Specifically, the first indirect traction member 161 passes through the inside of the fixed tube 170 and is connected to the brake handle 140.

[0068] When the radius of the first pulley 154 is greater than the radius of the second pulley 155, when the brake handle 140 is operated, since the input drive is the first pulley 154, therefore, a relatively small force can be used to drive the first indirect traction member 161, so that the direct traction member 111 can obtain a relatively large force, thereby improving the braking and non-braking effects. This is the force-saving but non-distance-saving mode.

[0069] When the radius of the first pulley 154 is less than the radius of the second pulley 155, when the brake handle 140 is operated, since the input drive is the first pulley 154, therefore, the first indirect traction member 161 moves a relatively small distance, and the direct traction member 111 can be made to move a relatively large distance, thereby also improving the braking and non-braking effects. This is the distance-saving but non-force-saving mode.

[0070] The mobile workbench provided in this embodiment transmits the power of the brake handle 140 through the integrated pulley assembly 150, can obtain the advantages of force-saving or distance-saving, and improves the braking and non-braking effects.

[0071] Embodiment V

[0072] Please refer to Figure 1 、 Figure 5 and Figure 6 As shown, in order to make the disassembly and assembly of the mobile workbench convenient, a quick-release structure 500 is proposed in Embodiment I. Therefore, this embodiment specifically discloses a quick-release structure 500, including:

[0073] A first tube body 10, and a first cavity 11 for installing a first electronic connector 50 is provided inside the first tube body 10;

[0074] A second tube body 20, and a second cavity 21 for installing a second electronic connector 60 is provided inside the second tube body 20. The first electronic connector 50 and the second electronic connector 60 are detachably and fixedly connected;

[0075] The buckle 40 is fixed on the first pipe body 10 or the second pipe body 20, and the first pipe body 10 is detachably and fixedly connected to the second pipe body 20 through the buckle 40.

[0076] Therefore, the first pipe body 10 can be fixedly connected or integrally formed with the pipe body to be connected (such as the first connecting pipe 300), and the second pipe body 20 can be fixedly connected or integrally formed with another pipe body to be connected (such as the fixed pipe 170), so as to realize the quick disassembly and assembly of the fixed pipe 170 and the first connecting pipe 300.

[0077] Moreover, the first device set located on the first connecting pipe 300 and the second device set located on the second connecting pipe 400 can obtain power through the connection between the first electronic connector 50 and the second electronic connector 60. For example, when the power obtained by the power cord 202 is transmitted to the control host 301 through the electronic connector, as an optional method, the first electronic connector 50 and the second electronic connector 60 are respectively a power plug and a power socket. Another example is that when the control host 301 supplies power to the LED lamp 401 and the camera 402 on the second connecting pipe 400, as an optional method, the first electronic connector 50 and the second electronic connector 60 are respectively a USB female port and a USB male port.

[0078] As an optional method of this embodiment, the buckle 40 includes: a clamping block 41, one end of the clamping block 41 is fixed on the outer wall of the first pipe body 10, and a limiting protrusion 43 is provided at the other end of the clamping block 41; a limiting hole 12 is opened on the first pipe body 10, and the limiting protrusion 43 sinks into the first cavity 11 through the limiting hole 12; a limiting groove 32 matched with the limiting protrusion 43 is provided on the second pipe body 20; when the second pipe body 20 is inserted into the first cavity 11, the limiting protrusion 43 is clamped into the limiting groove 32. Therefore, through the cooperation of the limiting protrusion 43 and the limiting groove 32, the detachable fixation between the first pipe body 10 and the second pipe body 20 is realized.

[0079] Furthermore, as an optional method of this embodiment, one end of the second pipe body 20 is provided with a branch pipe body 30 for fixing the second electronic connector 60, a third cavity 31 communicating with the second cavity 21 is provided in the branch pipe body 30, and the limiting groove 32 is opened on the outer wall of the branch pipe body 30. Therefore, through the branch pipe body 30, the connection between the first electronic connector 50 and the second electronic connector 60 can be further stabilized to prevent them from falling off.

[0080] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
