Detailed Description

Embodiments of the present application will be described in further detail below with reference to the drawings and examples. The following examples are intended to illustrate the present application but are not intended to limit the scope of the present application.

In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "top", "bottom", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only used for convenience in describing the embodiments of the present application and simplifying the description, but do not indicate or imply that the devices or elements referred to must have specific orientations, be configured in specific orientations, and operate, and thus, should not be construed as limiting the embodiments of the present application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An embodiment of the present application provides a drawing apparatus 1000, please refer to fig. 1, fig. 2, and fig. 3, including a mounting base 1 and a drawing body 2.

The mount 1 has a drawing space 1a and a first guide structure 11. The specific shape of the drawing space 1a is not limited, and the first guide structure 11 may be disposed at any suitable position of the mounting base 1.

The drawer body 2 is slidably arranged in the drawer space 1a, i.e. the drawer body 2 is slidable relative to the mount 1. The drawing body 2 is provided with a second guiding structure 21, one of the first guiding structure 11 and the second guiding structure 21 is a sliding groove extending along the drawing direction, and the other is a guide rail extending along the drawing direction, and the guide rail and the sliding groove are in sliding fit. That is, the longitudinal direction of the guide rail, the longitudinal direction of the chute, and the drawing direction coincide.

In the process of drawing the drawing body 2, the sliding fit of the guide rail and the sliding groove plays a guiding role in the drawing movement of the drawing body 2, so that the drawing body 2 can move directionally along the drawing direction.

The position of the drawing body 2 relative to the mounting seat 1 comprises a working position and a non-working position, when the drawing body 2 is in the working position, the drawing body 2 is accommodated in the drawing space 1a, and at the moment, the drawing body 2 is in the designed normal working position; in the inoperative position, the drawer body 2 is displaced in the drawing direction from the operative position, i.e. the drawer body 2 is displaced from the normal operating position described above, i.e. the drawer body 2 is in the inoperative position after the drawer body 2 has been drawn out.

It should be noted that, for the same drawer 1000, the working position of the drawer 2 is determined, that is, the position of the drawer 2 when the drawer 1000 is in the normal use state, for example, the position of the drawer 2 when moving inward to the limit position along the drawing direction is the working position.

When the drawer body 2 is in the working position, the guide rail and the chute are in clearance fit with a first clearance. That is, a certain gap is formed between the opposite side walls of the guide rail and the sliding groove, and the gap can reserve a certain space for the unexpected deformation of the drawer body 2 or the unexpected deformation of the mounting base 1 to a certain extent, so that the abnormal gap in the appearance of the drawing device caused by the unexpected deformation of the drawer body 2 is reduced or eliminated.

It should be noted that the unexpected deformation refers to deformation that is not a design, and is unexpected, for example, deformation caused by heat, moisture, plastic aging, etc.

When the drawer body 2 is in the inoperative position, the guide rail and the slide groove engage with a clearance in at least a partial section of the second clearance in the drawing direction, wherein the second clearance is smaller than the first clearance. It should be noted that the at least partial section of the guide rail and the runner in the pull-out direction is at least a partial length within the length range of the guide rail and the runner. When the user is at the in-process of the drawer body 2, because the guide rail and the spout carry out clearance fit with less second clearance in the at least partial section of pull orientation, consequently, can reduce the beat range of the drawer body 2 along the perpendicular to sliding direction effectively, can improve the rocking of the drawer body 2 effectively and feel, promote the user and use experience.

The pull device 1000 of the embodiment of the application has the advantages that the gap between the side walls of the guide rail and the sliding groove is changeable, the pull body 2 is located at the working position in a normal use state, a certain gap is reserved between the side walls of the guide rail and the sliding groove, and the problem that the appearance gap is poor due to product deformation can be solved. After the pulling body 2 is pulled, the gap between the side walls of the guide rail and the sliding groove is reduced, the shaking performance and the smooth action performance can be improved, the user experience feeling is improved, the smooth hand feeling of the pulling body 2 can be kept, and the situations that the pulling body 2 is blocked and pulled difficultly occurs in the pulling process are avoided.

It should be noted that, in the case where the drawer body 2 is smoothly drawn, the smaller the size of the second gap is, the better the limit effect on the drawer body 2 is.

The specific shape of the guide rail is not limited, and for example, in some embodiments, the guide rail takes the structural form of a rib, and it should be noted that the rib needs to have a proper width so that the rib has a proper structural strength.

The concrete shape of the sliding groove is not limited, and for example, a partial region of the drawer body 2 or the mounting seat 1 where the sliding groove is located may be recessed to form the sliding groove, or two ribs may be additionally arranged on the surface of the drawer body 2 or the mounting seat 1, and the sliding groove is formed between the two ribs.

It can be understood that the pull body 2 is supported in the mount pad 1 under the action of self gravity, and in the pull process, the pull body 2 has better smooth and easy degree along the upper and lower direction itself, and the influence on the user experience is less along rocking of the upper and lower direction, and the influence on the user experience is greater for the horizontal rocking of the perpendicular to sliding direction. For this purpose, in some exemplary embodiments, the top side or the bottom side of the chute is open, and the guide rail is located between two laterally opposite side walls of the chute, and the guide rail is inserted through the open portion of the chute. In this embodiment, the cooperation of the guide rail and the sliding groove can effectively limit the swing amplitude of the pulling body 2 along the transverse direction during the pulling process.

The way of realizing the variable fit clearance of the guide rail and the sliding groove is not limited.

It will be appreciated that the variation of the fit clearance of the guide rail and the runner can be achieved by a widening scheme of the first guide structure 11, and in other embodiments the variation of the fit clearance of the guide rail and the runner can be achieved by a widening scheme of the second guide structure 21.

For example, in some embodiments, referring to fig. 7, fig. 10, fig. 13 and fig. 14, along the length direction of the second guiding structure 21, the second guiding structure 21 includes a first section 211 and a second section 212 connected to each other, the first section 211 is connected to the front end of the second section 212 along the drawing direction, and the first section 211 and the second section 212 have different widths. The drawing direction refers to a direction in which the drawing body 2 is drawn, the drawing direction includes a direction in which the drawing is performed in a bidirectional direction, and the drawing direction is a direction in which the drawing is performed in a unidirectional direction.

For example, in some embodiments, referring to fig. 7, the width d1 of the first section 211 is smaller than the width d2 of the second section 212. In other embodiments, referring to fig. 15, the width d1 of the first segment 211 is greater than the width d2 of the second segment 212.

The second guide structure 21 is clearance-fitted with the first guide structure 11 with the second gap by the second section 212, and the second guide structure 21 is clearance-fitted with the first guide structure 11 with the first gap by the first section 211.

Specifically, referring to fig. 10 and 15, when the drawer body 2 is in the working position, the second guiding structure 21 is in clearance fit with the first guiding structure 11 only through the first section 211 with a first clearance.

Referring to fig. 13 and 14, when the drawer body 2 is in the non-operating state, the second guiding structure 21 is in clearance fit with the first guiding structure 11 by a second clearance through at least a portion of the second section 212. That is, after the drawer body 2 is drawn out from the working position for a certain distance, a part of the second section 212 starts to be in clearance fit with the first guide structure 11 with a second clearance, and at this time, the first guide structure 11 and the second section 212 have a certain engagement effect, so as to limit the lateral deflection of the second guide structure 21.

That is, in this embodiment, the fit clearance of the guide rail and the slide groove is variable by the widening scheme of the second guide structure 21.

It will be appreciated that the length of the second guiding structure 21 and the length L3 of the first guiding structure 11 may be equal or different, for example, the length of the second guiding structure 21 is greater than the length L3 of the first guiding structure 11, or the length of the second guiding structure 21 is less than the length L3 of the first guiding structure 11. Wherein the length of the second guiding structure 21 is the sum of the length L1 of the first section 211 and the length L2 of the second section 212.

For example, referring to fig. 13 and 14, when the drawer body 2 is moved to the extreme position in the drawing direction, the second guide structure 21 is only clearance-fitted with the first guide structure 11 by the second section 212 with a second clearance. That is, when the drawer body 2 is in the extreme position, the entire first guide structure 11 is in clearance fit with the second section 212 with a second clearance, so that the stability of the drawer body 2 in the extreme position can be improved.

It should be noted that the extreme positions are: the pull-out body 2 cannot be pulled out further without the pull-out body 2 being detached from the mounting base 1.

Illustratively, referring to fig. 13, the length L1 of the first section 211 is greater than the length L2 of the second section 212, and the length L1 of the first section 211 is not different from the length L3 of the first guiding structure 11, for example, the absolute value of the difference between the length L1 of the first section 211 and the length L3 of the first guiding structure 11 is not more than 1 cm. In this embodiment, in the working position, the first section 211 is matched with the first guide structure 11, so that the length matching of the two can be fully utilized, and the space required in the length direction is saved; when the drawer body 2 is drawn out, when the drawer body 2 starts to move, or when the drawer body 2 starts to move for a small distance, the second section 212 starts to be in clearance fit with the first guide structure 11 by a second gap, so that the shaking of the drawer body 2 when the drawer body starts to be drawn can be reduced, and the user experience is improved.

It will be appreciated that the second guide formation 21 should be as long as possible so that the second guide formation 21 and the first guide formation 11 still have a suitable mating length when the pull body 2 is extracted.

Illustratively, the length of the second guide structure 21 is 0.8 to 1 times, for example, 0.8, 0.85, 0.9, 0.94, 1 times, etc., the length of the drawer 2. This size range enables the second guide structure 21 to have a longer size, and improves the guiding reliability of the second guide structure 21.

It should be noted that the first guiding structure 11 may be a guide rail, and the second guiding structure 21 may be a sliding chute; the first guide structure 11 may be a sliding groove, and the second guide structure 21 may be a guide rail.

For example, in some embodiments, referring to fig. 4 to 13, the second guiding structure 11 is a guiding rail, and the first guiding structure 21 is a sliding chute. In this embodiment, the width d1 of the first section 211 is less than the width d2 of the second section 212. In other embodiments, referring to fig. 14 and 15, the second guiding structure 11 is a sliding slot, the first guiding structure 21 is a guiding rail, and the width d1 of the first section 211 is greater than the width d2 of the second section 212.

In other embodiments, the variable fit clearance of the guide rail and the slide groove is achieved by a widening of the first guide structure 11. Specifically, along the length direction of the first guiding structure 11, the first guiding structure 11 includes a third section and a fourth section that are connected to each other, the fourth section is connected to the front end of the third section along the drawing direction, the widths of the third section and the fourth section are different, when the drawing body 2 is in the working position, the first guiding structure 11 is in clearance fit with the second guiding structure 21 with a first clearance only through the third section, and when the drawing body 2 is in the non-working position, the first guiding structure 11 is in clearance fit with the second guiding structure 21 with a second clearance through at least a part of the fourth section.

It should be noted that the manner of the third section and the fourth section can be implemented with reference to the manner of the first section 211 and the second section 212. For example, the sliding groove in fig. 13 may be provided on the drawer body, and the guide rail in fig. 13 may be provided on the mounting seat; for another example, the guide rail in fig. 14 may be provided on the drawer body, and the slide groove in fig. 14 may be provided on the mounting base.

Exemplarily, the second guiding structure 21 is located on the bottom surface of the drawing body 2, a portion of the sidewall of the mounting socket 1 below the drawing space 1a protrudes inward to form a supporting region 12b, and the first guiding structure 11 is disposed on the top surface of the supporting region 12 b. It should be noted that the bottom surface refers to a surface of the drawer 2 facing downward, and does not limit the height position of the bottom surface. That is, the bottom surface may be at the lowest position of the drawer body 2 or may not be at the lowest position.

In the embodiment of the application, the number of the guide rails and the sliding grooves is only one group. That is to say that the drawer 2 is provided with only one second guide structure 21 and/or the mounting 1 is provided with only one first guide structure 11. The jamming probability of the first guide structure 11 and the second guide structure 21 can be reduced by the sliding fit of only one set of guide rails and sliding grooves.

It should be noted that in some embodiments, the number of the second guiding structures 21 is one, and the number of the first guiding structures 11 is one. In other embodiments, the number of second guiding structures 21 is multiple and the number of first guiding structures 11 is one, wherein only one second guiding structure 21 cooperates with a first guiding structure 11. In other embodiments, the number of first guiding structures 11 is multiple and the number of second guiding structures 21 is one, wherein only one first guiding structure 11 is engaged with the first guiding structure 11.
