Description

Technical Field

[0001] The utility model relates to a technical solution for quickly adjusting household appliances such as air purifiers, humidifiers, humidification and purification all-in-one machines between fixed installation and free push states, and specifically relates to a brake device. Background Art

[0002] At present, large-volume floor-standing household appliances with more humanized designs are generally provided with universal wheels to facilitate users to easily move and change the placement of the household appliances, but they must be equipped with a brake device to stably and safely fix the household appliances in the desired position.

[0003] In the traditional solution, brakes are installed on universal wheels, especially when the brakes are designed on the wheels. Such a design will affect the height of the wheels, making the wheels higher, which will cause the entire machine to become higher and affect the overall appearance and structure. In addition, the brakes are at the bottom of the wheels, which is inconvenient to use. Complicated operations are required to achieve braking and restarting, and the user experience is not good.

[0004] Based on this, the inventor has conducted in-depth research on the universal wheel of household appliances and the related brake system, hoping to design a new brake device that can solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned problems, the inventors have conducted intensive research and designed a braking device, in which the universal wheel and the brake assembly are separately arranged, thereby reducing the height and structural complexity of the universal wheel, and the brake fixation of the household appliance is completed by a separately controlled brake assembly. The structure is simple, the operation is convenient, and one-key fixation and one-key start can be achieved. Specifically, a lifting brake assembly that can be extended downward is arranged at the lower side of the bottom plate of the main unit, and the universal wheel is suspended by extending the lifting brake assembly. The household appliance is supported only by the lifting brake assembly, so that the purpose of stable braking and fixation can be achieved. When the household appliance needs to be pushed, the lifting brake assembly can be controlled to retract so that the universal wheel can bear the force again, and the pushing and moving in any direction can be performed, thereby completing the utility model.

[0006] Specifically, the purpose of the utility model is to provide a brake device, which includes a main body bottom plate 1, a universal wheel 2, a lifting brake assembly 3 and a cover plate 4;

[0007] A receiving groove 11 for installing the lifting brake assembly 3 is provided at the lower side of the main body bottom plate 1, and a latch hole 102 is provided on the side wall of the receiving groove 11. The lifting brake assembly 3 can move in the vertical direction in the receiving groove 11.

[0008] Two latches 303 whose axes coincide and are placed horizontally are arranged in the lifting brake assembly 3, and a latch spring 503 is arranged between the two latches 303, and the latch spring 503 pushes the latch 303 outward so that the end of the latch 303 abuts against the side wall of the receiving groove 11;

[0009] When the lifting brake assembly 3 extends downward from the receiving groove 11 and contacts the ground 6, the brake device enters a brake fixed state. At this time, the latch 303 is inserted into the latch hole 102 under the action of the latch spring 503, so that the brake device remains in the brake fixed state.

[0010] When the lifting brake assembly 3 is retracted and returned to the accommodating groove 11 and the lifting brake assembly 3 is out of contact with the ground 6, the brake device enters a free walking state.

[0011] The universal wheel 2 is installed at the bottom of the main machine base plate 1. When the vehicle enters a free walking state, the universal wheel 2 abuts against the ground 6. When the vehicle enters a brake fixing state, the universal wheel 2 is out of contact with the ground 6.

[0012] Among them, a lifting spring 501 is provided in the lifting brake assembly 3, which passes through the lifting brake assembly 3 from top to bottom. The top end of the lifting spring 501 is fixed to the upper wall surface of the accommodating groove 11, and the bottom end of the lifting spring 501 is fixed to the cover plate 4 located at the bottom of the lifting brake assembly 3. The lifting brake assembly 3 is pulled upward by the lifting spring 501 and the cover plate 4.

[0013] A button 302 is provided on the side of the lifting brake assembly 3, and a button slope 3021 is provided inside the button 302.

[0014] The latch 303 is provided with a latch bevel 3031.

[0015] When the button 302 is pressed inward, the button slope 3021 squeezes the latch slope 3031, so that the latch 303 overcomes the elastic force of the latch spring 503 and moves inward, and then the latch 303 disengages from the latch hole 102, and the lifting brake assembly 3 can shrink back to the accommodating groove 11 and enter a free walking state.

[0016] A button spring 502 is further disposed inside the button 302 , and the button spring 502 pushes the button 302 outward, so that the button 302 can return to its original position when there is no external force pressing on it.

[0017] A ground pressing spring 504, a ground pressing sleeve 304 and a ground pressing rubber block 305 are provided at the bottom of the lifting brake assembly 3. The ground pressing sleeve 304 covers the upper outer side of the ground pressing rubber block 305, and the bottom of the ground pressing rubber block 305 is exposed to the outside and can directly contact the ground 6.

[0018] The ground-pressing sleeve 304 is connected to the main frame 301 of the lifting brake assembly 3 through a ground-pressing spring 504;

[0019] When the brake device enters the brake fixed state, the bottom of the ground-pressing rubber block 305 abuts against the ground 6, and the ground-pressing spring 504 is in a compressed state.

[0020] The beneficial effects of the utility model include:

[0021] (1) According to a brake device provided by the utility model, the lifting brake assembly is arranged on both sides of the machine, which is convenient for users to use, and because it is on the side, the universal wheel can be made smaller, thereby reducing the height of the machine;

[0022] (2) According to a brake device provided by the utility model, a ground-pressing spring and a ground-pressing rubber block are provided in the device, which can cooperate with uneven ground, that is, to achieve stable fixation of the machine on uneven ground.

[0053] The present invention is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present invention will become clearer and more specific.

[0054] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0055] According to the utility model, a brake device is provided, such as Figure 1 As shown in , the brake device includes a main body bottom plate 1, a universal wheel 2, a lifting brake assembly 3 and a cover plate 4;

[0056] The host base plate 1 and the household appliances thereon are an integrated structure, and the household appliances can be any household appliances selected as needed, and can be an air purifier, a humidifier, an all-in-one humidifier and purifier, a refrigerator, a washing machine, etc.

[0057] A receiving groove 11 for installing the lifting brake assembly 3 is provided at the lower side of the main body bottom plate 1. The lifting brake assembly 3 can move in the vertical direction in the receiving groove 11, and then extend downward from the receiving groove 11 and abut against the ground 6 to enter a brake fixed state; or shrink back into the receiving groove 11, so that the lifting brake assembly 3 is out of contact with the ground 6 and enters a free walking state.

[0058] In the present application, the upward movement of the lifting brake assembly 3 can be driven by the stretching force of the lifting spring 501, and the downward movement of the lifting brake assembly 3 can be achieved by manual pressing or by adding an additional driving device, such as a pneumatic pump or a hydraulic cylinder, etc.

[0059] Preferably, the universal wheel 2 is installed at the bottom of the mainframe bottom plate 1, and when entering the free walking state, Figure 3 As shown in FIG, the universal wheel 2 abuts against the ground 6, and when the brake is in the fixed state, as shown in FIG. Figure 4 As shown in FIG, the universal wheel 2 is out of contact with the ground 6.

[0060] Preferably, a lifting spring 501 is provided in the lifting brake assembly 3, which passes through the lifting brake assembly 3 from top to bottom. The top of the lifting spring 501 is fixed to the upper wall surface of the accommodating groove 11, and the bottom of the lifting spring 501 is fixed to the cover plate 4 located at the bottom of the lifting brake assembly 3, so that the lifting brake assembly 3 is pulled upward by the lifting spring 501 and the cover plate 4. Preferably, the cover plate 4 is screwed and fixed to the main frame 301 of the lifting brake assembly 3 by bolts.

[0061] Preferably, two latches 303 with overlapping axes and placed horizontally are provided in the lifting brake assembly 3, that is, the two latches 303 are symmetrically arranged, and a latch spring 503 is arranged between the two latches 303. The latch spring 503 is in a compressed state, and the latch 303 is pushed outward by the latch spring 503, so that the end of the latch 303 abuts against the side wall of the receiving groove 11; preferably, the main frame 301 provided outside the latch 303 and the latch spring 503 can provide a limit, so that the latch 303 and the latch spring 503 can only move back and forth along the axis direction of the latch 303. Figure 5 , Figure 6 and Figure 7 as shown in .

[0062] A latch hole 102 is provided on the side wall of the receiving groove 11. When the lifting brake assembly 3 moves downward in the receiving groove 11 along the vertical direction to enter the brake fixing state, the latch 303 is inserted into the latch hole 102 under the action of the latch spring 503, so that the brake device is kept in the brake fixing state. Figure 5 as shown in .

[0063] A button 302 is provided on the side of the lifting brake assembly 3, and a button slope 3021 is provided inside the button 302.

[0064] The latch 303 is provided with a latch bevel 3031. Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown in;

[0065] When the button 302 is pressed inward, the button slope 3021 squeezes the latch slope 3031, so that the latch 303 overcomes the elastic force of the latch spring 503 and moves inward, and then the latch 303 disengages from the latch hole 102, and the lifting brake assembly 3 can shrink back to the accommodating groove 11 and enter a free walking state.

[0066] Preferably, a button spring 502 is further provided inside the button 302, and the button spring 502 pushes the button 302 outward so that the button 302 can return to its original position when no external force is applied. Preferably, a limit rod is provided inside the button spring 502 to limit the freedom of the button 302 so that the button 302 can only move back and forth in one direction. Accordingly, a waist-shaped hole is provided on the latch 303 for the button spring 502 and the limit rod to pass through.

[0067] Among them, a ground pressing spring 504, a ground pressing sleeve 304 and a ground pressing rubber block 305 are arranged at the bottom of the lifting brake assembly 3, the ground pressing sleeve 304 is covered on the upper outer side of the ground pressing rubber block 305, and the bottom of the ground pressing rubber block 305 is exposed to the outside and can directly contact the ground 6; the ground pressing rubber block is made of soft rubber material, which can better increase the friction of contacting the ground and protect the ground.

[0068] The ground-pressing sleeve 304 is connected to the main frame 301 of the lifting brake assembly 3 through a ground-pressing spring 504;

[0069] When the brake device enters the brake fixed state, the bottom of the ground-pressing rubber block 305 abuts against the ground 6, and the ground-pressing spring 504 is in a compressed state.

[0070] In the present application, the lowest part of the lifting assembly is the ground-pressing rubber 305, and the lowest position of the ground-pressing rubber block 305 is lower than the ground 6, so that the ground-pressing rubber block 305 is pressed tightly against the ground under the elastic force of the ground-pressing spring 504. In the present application, such a design enables the brake device to match the uneven ground. Considering that the main frame 301 is hard plastic, if it directly contacts the ground, it is bound to be uneven. Under the joint action of the ground-pressing spring 504 and the ground-pressing rubber block 305, the brake device can be stably stopped and fixed even on an uneven ground.

[0071] The present invention has been described above in conjunction with preferred embodiments, but these embodiments are only exemplary and serve only as an illustration. On this basis, the present invention may be subjected to a variety of substitutions and improvements, all of which fall within the scope of protection of the present invention.
