Description

Technical Field

[0001] The utility model relates to the technical field of transport devices, in particular to a single-board support type mobile bracket and a household appliance. Background Art

[0002] For household appliances such as washing machines, freezers, and refrigerators, due to their large size and heavy weight, it is inconvenient to move or it is time-consuming and laborious to move them. There are two ways to move heavier household appliances (such as washing machines or refrigerators): using a transfer forklift and manual handling. However, in home use scenarios, a transfer forklift is not a reasonable choice, and manual handling is also difficult. In the prior art, there is a solution of installing a mobile bracket at the bottom of the household appliance, which allows the household appliance to be lifted by such a mobile bracket, and then the household appliance is moved by dragging such a mobile bracket.

[0003] A Chinese utility model patent with publication number CN218001033U discloses a seesaw type mobile bracket, comprising an outer groove plate for connecting household appliances, an inner groove plate located inside the outer groove plate and capable of sliding relative to the outer groove plate, a plurality of lifting components evenly spaced on the outer groove plate and the inner groove plate and used for lifting and moving the household appliances, and a wrench component for driving the inner groove plate to slide; the lifting component comprises a seesaw piece hinged at one end to the side wall of the outer groove plate, a load-bearing wheel located at the other end of the seesaw piece, a lifting shaft passing through the outer groove plate and the inner groove plate and capable of moving up and down, and an inclined slide groove opened along the side wall of the inner groove plate and used for the lifting shaft to slide, and the wrench component is rotated, the inner groove plate slides relative to the outer groove plate, and the lifting shaft moves obliquely upward relative to the inclined slide groove, driving the load-bearing wheel to lift upward.

[0004] In the prior art, when the mobile bracket is adjusted to the lifting state, the height of the inner groove plate relative to the outer groove plate does not change, and the inner groove plate slides parallel to the outer groove plate, so that the separate lifting assembly drives the roller to lift. For this existing solution, on the one hand, during the lifting process of the lifting assembly, the bottom surface of the inner groove plate with the largest area always rubs against the outer groove plate, and the resistance encountered by the rotating wrench assembly is always large. On the other hand, since the inner groove plate and the lifting assembly are two independent parts, a separate lifting assembly needs to be provided, which increases the number of parts of the mobile bracket, resulting in an increase in cost and total product weight, and also increases the difficulty of product assembly.

[0076] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0077] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of description, and are not used to limit the scope of implementation. The change or adjustment of their relative relationship should also be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0078] In one embodiment, if Figure 1-4 As shown in , 6, 8-9, and 12, the single-board support type mobile bracket includes an outer plate 101, an inner moving member 201, and a transmission mechanism. A roller 203 is installed on the inner moving member 201, and the inner moving member 201 and the roller 203 are driven to rise together through the transmission mechanism, so that the single-board support type mobile bracket is in a raised state.

[0079] When the roller 203 of the utility model is lifted, the height of the inner moving part 201 relative to the outer plate 101 will change, that is, the bottom surface of the inner moving part 201 does not need to always rub against the outer plate 101, thereby reducing the resistance that needs to be overcome when the roller 203 is lifted, making the single-board supporting type mobile bracket more labor-saving when used.

[0080] In addition, since the roller 203 of the utility model is installed on the inner moving part 201, there is no need to set up a lifting component separately. Omitting the lifting component can save raw materials of the product, reduce the total weight of the product, simplify the product structure, and reduce the difficulty of product assembly.

[0081] Side walls 102 are provided on both sides of the outer plate 101, and parallel inclined grooves 103 are provided on the side walls 102. When the transmission mechanism drives the inner moving member 201 to move to one end of the inclined groove 103, the roller 203 partially protrudes from the side wall 102, and the inner moving member 201 is in a raised state; when the transmission mechanism drives the inner moving member 201 to move to the other end of the inclined groove 103, the roller 203 falls back, and the inner moving member 201 is in a lowered state.

[0082] The side of the outer plate 101 may be provided with side walls 102 only at some positions, or may be provided with side walls 102 of equal height at all positions. The side of the outer plate 101 may also be provided with side walls 102 of greater height at some positions, and side walls 102 of less height at other positions. Preferably, the side wall 102 where the inclined groove 103 is required to be provided has a greater height, and the side wall 102 provided at other positions may be less in height than that there.

[0083] In addition, chute 103 climbs obliquely along the height direction of sidewall 102, that is, chute 103 climbs obliquely upward. The angle of inclination of chute 103 is 12 degree~25 degree, for example can be 18 degree, also can be 20 degree, or can be 25 degree etc. It should be noted that the angle of inclination of chute 103 is not limited to the above-mentioned scope, can also be greater than 25 degree and less than 40 degree angle of inclination. If the angle of inclination of chute 103 is less, then need longer chute 103 length just can make interior moving member 201 rise to required height, at this moment, transmission mechanism driving stroke is required higher. If the angle of inclination of chute 103 is larger, then be difficult to make interior moving member 201 move along chute 103.

[0084] Connecting shaft 106 is installed on the interior moving member 201, and this connecting shaft 106 runs through chute 103, and can slide along chute 103.When interior moving member 201 moves to the other end from chute 103 one end along with connecting shaft 106, the spacing between interior moving member 201 and the outside plate 101 can increase, and roller 203 lifts, and interior moving member 201 lifts, and this moment, mobile support is in lifting state.When interior moving member 201 returns along chute 103 along with connecting shaft 106, the spacing between interior moving member 201 and the outside plate 101 can reduce, and roller 203 falls back, and interior moving member 201 descends, and this moment, mobile support is in descending state.

[0085] Can drive interior moving member 201 to move along skewed slot 103 by transmission mechanism, thereby make single board support type mobile support switch between lifting state and descending.For transmission mechanism, in one embodiment, transmission mechanism comprises wrench 301 that is hinged by wrench shaft 302 with outside plate 101 and connecting rod assembly that is connected with wrench 301, one end of connecting rod assembly is connected with connecting shaft 106, can move with interior moving member 201, thereby lift or descend with respect to outside plate 101.The other end of connecting rod assembly can move horizontally with wrench 301 with respect to outside plate 101.In this scheme, rotate wrench 301, can make connecting rod assembly one end transverse displacement, the interior moving member 201 that the other end pulls moves along skewed slot 103, because interior moving member 201 height is changing, so the other end height of connecting rod assembly also can change, thereby can drive interior moving member 201 along skewed slot 103 by transmission mechanism, thereby change the spacing between interior moving member 201 and outside plate 101.

[0086] Regarding the rotation direction of the wrench 301 , the wrench 301 can be rotated from a state substantially perpendicular to the outer panel 101 to a state substantially parallel to the outer panel 101 , or from a state substantially parallel to the outer panel 101 to a state substantially perpendicular to the outer panel 101 .

[0087] The rollers 203 are disposed near the two end portions of the inner moving member 201 . It should be noted that the rollers 203 may be installed at other positions of the inner moving member 201 in addition to the two end portions.

[0088] If the wheel surface of the roller 203 protrudes from the inner moving part 201 by a small height, the roller 203 may not be able to rotate when the single-board support type mobile bracket carries a heavy object. Therefore, in this solution, the wheel surface of the roller 203 partially protrudes from the inner moving part 201, and the protruding height is 1 to 10 mm, such as 1.8 mm, 2 mm, 3 mm, 3.8 mm, 5 mm, 7 mm, 8 mm, 10 mm, etc.

[0089] The larger the diameter of the roller 203, the easier it is to drag the mobile bracket when the roller 203 is raised. Since the height of the side wall 102 of the outer plate 101 is limited, the height of the inner moving member 201 is also limited. In order to install a larger roller 203 as much as possible in the inner moving member 201 of limited height, Fig.14 As shown, an avoidance groove 204 is provided on the inner moving member 201 below the roller 203, so that more installation space can be reserved for the roller 203, so that a roller 203 of a larger size can be installed.

[0090] When the inner moving member 201 is not in the lifted state, the roller 203 may or may not protrude from the side wall 102 , and the wheel surface of the roller 203 may also be flush with the side wall 102 .

[0091] Since the mobile support of the utility model needs to bear the load when lifting and moving heavy objects, it is necessary to avoid the situation that the inner moving member 201 in the lifting state slides along the chute 103. In this embodiment, a limiting recess 108 is provided at the end of the chute 103. When the inner moving member 201 is in the lifting state and the outer plate 101 bears the load, the connecting shaft 106 is located in the limiting recess 108. When the mobile support is dragged and the roller 203 is subjected to the lateral force, the roller shaft will not move from the limiting recess 108 to the chute 103, that is, the roller 203 will not fall back when the mobile support is dragged, thereby ensuring that the inner moving member 201 is always in the lifting state during the dragging process.

[0092] Since there is a gap between the inner moving member 201 and the outer plate 101 when the mobile support of the utility model is in the lifting state, it can be regarded that only the outer plate 101 plays a supporting role. At this time, the thickness of the outer plate 101 cannot be too thin, that is, it is necessary to make its strength meet the requirements. Therefore, in this embodiment, the thickness of the outer plate 101 is 1.3-2.0 mm, such as 1.3 mm, 1.5 mm, 1.8 mm, or 2.0 mm. It should be noted that if a higher strength outer plate 101 is used, the thickness of the outer plate 101 can also be less than 1.3 mm, such as 1.0 mm, or 1.2 mm. When the weight of the product does not need to be considered, the thickness of the outer plate 101 can also be greater than 2.0 mm, such as 2.2 mm or 3.4 mm.

[0093] As for the connecting rod assembly, in one embodiment, the connecting rod assembly includes a swing rod 105 and a translation member 304, and the translation member 304 is in transmission connection with the wrench 301. The lifting end of the swing rod 105 is hinged to the inner moving member 201, and the translation end of the swing rod 105 is hinged to the translation member 304 through the third hinge shaft 104. When the wrench 301 rotates, it can drive the translation end of the swing rod 105 to translate, and at the same time, the lifting end of the swing rod 105 moves with the inner moving member 201, and is lifted or lowered relative to the outer plate 101.

[0094] The connecting rod assembly further includes a connecting rod 303, one end of which is hinged to the wrench 301 through a first hinge axis, and the other end of which is hinged to the translation member 304 through a second hinge axis. For each hinge axis, it should be noted that the axes of the first hinge axis and the second hinge axis are perpendicular to the bottom surface of the outer plate 101, and the axes of the third hinge axis 104 and the connecting axis 106 are parallel to the bottom surface of the outer plate 101.

[0095] When the wrench 301 is rotated, the translation end of the swing rod 105 is driven to translate through the connecting rod 303 and the translation member 304 , and the lifting end of the swing rod 105 can be lifted or lowered along with the inner moving member 201 .

[0096] Other mechanisms in the prior art may also be used for the connecting rod 303 , as long as it can make the translation member 304 translate when the wrench 301 is rotated. This is relatively mature in the prior art and will not be described in detail here.

[0097] In one embodiment, the translation member 304 is connected to the outer plate 101 via a guide portion, and the guide portion is used to enable the translation member 304 to only translate along the outer plate 101. By providing the guide portion so that the translation member 304 can only translate, the translation end of the swing rod 105 and the connecting rod 303 can be restricted from vertical displacement, thereby avoiding damage to these mechanisms, and also enabling the connecting rod assembly composed of these mechanisms to continuously enable the translation end of the swing rod 105 to only translate, while the lifting end of the swing rod 105 can be lifted or lowered along with the inner moving member 201.

[0098] As for the guide part, the guide part includes a slide groove 107 provided on the side wall 102, and the slide grooves 107 provided on the side walls 102 at both ends are parallel to each other. Fig.12 As shown, the slide slot 107 is a through slot, and the end of the third hinge shaft 104 passes through the through slot. Fig.13 As shown, the slide slot 107 is a groove, and the end of the third hinge shaft 104 is inserted into the groove.

[0099] There are several implementation schemes for installing the roller 203: Figure 6 As shown, the roller 203 is mounted on the connecting shaft 106 between the side walls 102. Figure 3-4 As shown, the end of the connecting shaft 106 passes through the inclined slot 103 and extends out of the side wall 102, and rollers 203 are installed at both ends of the connecting shaft 106. Figure 1-2 As shown in 8-9, the roller 203 is installed on the inner moving part 201 through the roller shaft.

[0100] In one embodiment, the utility model provides a single-board support type mobile bracket. The other structures in this embodiment are the same as those in the above embodiment, except that:

[0101] Roller 203 is installed on the inner moving member 201 by roller shaft, and there is a gap between inner moving member 201 and sidewall 102, and this gap can provide space for the end rotation of roller shaft. When roller 203 two ends are installed by riveting, then need to provide this gap to provide space for riveting.

[0102] In order to avoid scratches between the inner moving part 201 and the side wall 102, a gasket is installed on the connecting shaft 106 between the side wall 102 and the inner moving part 201. This gasket can also reduce the friction when the inner moving part 201 moves relative to the side wall 102, thereby making the product more labor-saving when used.

[0103] In this embodiment, if Fig.12 As shown, the slide slot 107 is a through slot, and the end of the third hinge shaft 104 passes through the slide slot 107. The extension direction of the slide slot 107 is parallel to the length direction of the outer plate 101, so that the translation member 304 can only translate.

[0104] For the inner moving member 201, the following embodiments may be provided:

[0105] The first type: the inner moving member 201 has side edges 202 on both long sides. The side edges 202 have through holes corresponding to the inclined slots 103, and the end of the connecting shaft passes through the through holes and is inserted into the inclined slots 103. It should be noted that the roller 203 partially protrudes from the side edges 202. In this embodiment, Figure 5 As shown, the inner moving member 201 is an integrated structure, the two ends of which are roughly U-shaped groove plates, and the middle part is a strip plate.

[0106] The second type: the inner moving member 201 has side edges 202 on both long sides. The side edges 202 are provided with through holes corresponding to the inclined slots 103, and the end of the connecting shaft passes through the through holes and is inserted into the inclined slots 103. It should be noted that at this time, the roller 203 partially protrudes from the side edges 202. The inner moving member 201 is a split structure, and its two ends are roughly U-shaped groove plates, and the middle part is a strip plate, and the two ends of the strip plate are detachably connected to the groove plate, for example, they can be bolted or snap-fitted.
