Detailed Description
The present invention will be described in detail below with reference to the embodiments shown in the drawings, and in detail, reference is made to fig. 1-9, which illustrate preferred embodiments of the present invention, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. It should be understood that these embodiments are not intended to limit the present invention, and that functional, method, or structural equivalents and alternatives falling within the scope of the present invention may be modified by any person skilled in the art to include such embodiments.
In the description of the present invention, the azimuth or positional relationship indicated by the terms "upper", "lower", "front", "rear", etc. are based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific azimuth, and thus should not be construed as limiting the present invention. For example, in the following description, the lower side in fig. 2 is the front, and the upper side is the rear.
Fig. 1 illustrates a partially schematic perspective view of an embedded refrigerator according to an embodiment of the present invention. Fig. 2 shows a schematic top view (with hinges removed) of a built-in refrigerator according to an embodiment of the present invention, wherein only one side of the cabinet 4 is shown, in actual installation, the built-in refrigerator is built-in entirely into the cabinet 4. It will be appreciated that the recessed refrigerator need not be embedded in the cabinet 4, but may be embedded in a wall. As shown in fig. 1 and 2, the built-in refrigerator is consistent with the prior art refrigerator structure, and generally includes a cabinet 1 and a door 2 rotatably coupled to the cabinet 1 through a hinge 3. The door body 2 includes a front wall 22, a hinge mounting side 23, and a pivoting side 21, and the front wall 22 of the door body 2 is a side of the built-in refrigerator facing the external environment when built-in to the cabinet 4. The hinge mounting side 23 of the door body 2 is the upper side of the door body 2, i.e., one end of the hinge 3 is mounted on the hinge mounting side 23, and the other end of the hinge 3 is mounted on the upper side of the cabinet 1 of the refrigerator. The pivoting side 21 of the door 2 is the side on which the door 2 rotates around the housing 1.
The invention provides a method for determining a door body rotation axis of an embedded refrigerator, which comprises the following steps:
acquiring a preset maximum door opening angle of the door body 2;
fitting a first track line, wherein when the rotation axis of the door body is positioned on the first track line, the actual maximum door opening angle of the door body 2 is equal to the preset maximum door opening angle;
the target area is determined to be located on the side of the first trajectory line away from the pivoting side 21, and during the rotation of the door body 2, the door body rotation axis is determined to be located in the target area or on the boundary line of the target area.
It will be appreciated that in embodiments having only the first trajectory, the above-mentioned boundary line refers to the first trajectory.
Specifically, the door body rotation axis may be a physical axis or a virtual axis. For example, when the hinge 3 is a single-axis hinge, the rotation axis of the door body is the axis of the rotation shaft in the single-axis hinge, that is, the solid axis. When the hinge 3 is a multi-axis hinge, the rotation axis of the door body is a virtual axis defined by multiple axes in the multi-axis hinge.
When the position of the door body rotation axis is debugged on the first track line, the actual maximum door opening angle of the door body 2 is equal to the preset maximum door opening angle, and when the position of the door body rotation axis is debugged on one side, away from the pivoting side 21, of the first track line, the actual maximum door opening angle of the door body 2 is larger than the preset maximum door opening angle. When the door body rotation axis is adjusted on the side, close to the pivoting side 21, of the first track line, the actual maximum door opening angle of the door body 2 is smaller than the preset maximum door opening angle.
In the present invention, the requirement of the opening of the door body is that the actual maximum opening angle of the door body 2 is greater than or equal to the preset maximum opening angle, so that the target area is determined to be located at the side of the first track line away from the pivoting side 21, so that the actual maximum opening angle of the door body 2 is not less than the preset maximum opening angle.
It can be understood that, according to the finally determined positional relationship between the door body rotation axis and the first track line, the technician can know the magnitude relationship between the actual maximum door opening angle of the final door body 2 and the preset maximum door opening angle.
It should be noted that, the above-mentioned door body rotation axis being located in the target area or located on the boundary line of the target area may be understood that, during the rotation of the door body 2, the door body rotation axis is always located at a point in the target area or always located at a point on the boundary line of the target area; it is also understood that the door body rotation axis moves on the target area and/or the boundary line of the target area during the rotation of the door body 2.
Further, "fitting the first trajectory line" specifically includes the following steps:
referring to fig. 4, an XY coordinate system is constructed by taking a first intersection line of the front wall 22 of the door body 2 and the hinge mounting side 23 of the door body 2 in the closed state as an X axis, a second intersection line of the pivot side 21 of the door body 2 and the hinge mounting side 23 of the door body 2 in the closed state as a Y axis, and an intersection point of the X axis and the Y axis as an origin O;
And drawing the first track line in the XY coordinate system according to the formula x=y, wherein V represents the preset maximum door opening angle, and A represents a first gap between the pivoting side of the door body and the cabinet when the door body is in a closed state.
Further, the range of y in the formula x=y is equal to or less than 0 and equal to or less than T in tan v/2-a, wherein T represents the thickness value of the gate body. So that the determined target area is located within the thickness value range of the door body 2 when in the closed state. Of course, the invention is not limited thereto, and in the embodiment in which the door body rotation axis is disposed outside the door body 2, the value range of y may be adaptively enlarged, for example, -T/2 is equal to or greater than y and equal to or less than T; or the range of y may be set so that the target area is located on the hinge mounting side 23 of the door body 2 in the closed state, so as to facilitate the setting of the hinge shaft.
Preferably, in the formula x=y, tan v/2-a, 0.ltoreq.y.ltoreq.t/4 when a=3; when A=4, y is more than or equal to 0 and less than or equal to 3T/10; when A=6, y is more than or equal to 0 and less than or equal to 2T/5; when A=10, y is more than or equal to 0 and less than or equal to T/2; when A=18, 0.ltoreq.y.ltoreq.3T/5.
Specifically, the method for obtaining the formula x=y×tan v/2-a is as follows: the coordinates of the door body rotation axis on an XY coordinate system are set as (x, y), wherein x represents the abscissa of the door body rotation axis, and y represents the ordinate of the door body rotation axis. As shown in fig. 3, assuming that V is a preset maximum door opening angle, the cabinet 4 has a point D on the same horizontal line as the origin, a circle is drawn by taking the rotation axis of the door body as a circle point, the distance from the rotation axis of the door body to the point D is a radius, the intersection point of the circle and the front edge of the hinge mounting side 23 when the door body 2 is in the closed state is a point E, the included angle between the connection line of the rotation axis of the door body and the point D and the connection line of the rotation axis of the door body and the point E is the angle V through which the door body 2 rotates, and in addition, since the front wall 22 of the door body 2 in the closed state is flush with the front end of the cabinet 4, i.e. the point D and the point E are on the same horizontal line, an angle V can be bisected by making a line perpendicular to the front wall 22 of the door body 2 from the circle center, i.e. v=2w, and tan w= (x+a)/y, the decomposition formula can obtain x=y.
Assuming that the thickness T and the first gap a of the door body 2 are fixed values, a first trajectory G as shown in fig. 4 may be drawn according to the above-described solved formula and the y range 0+_y, and may be obtained as a straight line, where the actual maximum door opening angle of the door body 2 is equal to the preset maximum door opening angle when the door body rotation axis is located on the first trajectory G, where the actual maximum door opening angle of the door body 2 is greater than the preset maximum door opening angle when the door body rotation axis is located on a side of the first trajectory G away from the pivoting side 21, and where the actual maximum door opening angle of the door body 2 is less than the preset maximum door opening angle when the door body rotation axis is located on a side of the first trajectory G near the pivoting side 21.
Further, the determining method further comprises the following steps:
an XY coordinate system is constructed with the first intersection line of the front wall 22 of the door body 2 and the hinge mounting side 23 of the door body 2 in the closed state being an X axis, the second intersection line of the pivot side 21 of the door body 2 and the hinge mounting side 23 of the door body 2 in the closed state being a Y axis, and the intersection point of the X axis and the Y axis being an origin O;
as shown in fig. 6, a second trajectory H is drawn in the XY coordinate system according to the formula x=y; when the door body rotation axis is located on the second track line, the third gap between the front wall 22 of the door body 2 and the cabinet 4 when the door body 2 rotates to 90 degrees is equal to the first gap between the pivoting side 21 of the door body 2 and the cabinet 4 when the door body 2 is in the closed state
The target area is determined to be located at the same time on the side of the second trajectory line close to the pivoting side 21.
When the door body rotation axis is located on the second track line H, the third gap between the front wall 22 of the door body 2 and the cabinet 4 when the door body rotates to 90 ° is equal to the first gap between the pivoting side 21 of the door body 2 and the cabinet 4 when the door body is in the closed state, that is, the door body 2 does not move inwards, so that the user is not affected in taking and placing the articles; when the door body rotation axis is located at one side of the second trajectory H near the pivoting side 21, the third gap is smaller than the first gap when the door body 2 rotates to 90 °, that is, the door body 2 moves outwards when rotating to 90 °, which is more beneficial for a user to take and put articles; when the door body rotation axis is located at a side of the second trajectory H away from the pivoting side 21, the third gap is larger than the first gap when the door body rotates to 90 °, that is, the door body 2 rotates to 90 ° and moves inwards, at this time, the door body 2 shields a storage space of a part of the storage compartment, so as to affect a user to take and put objects. Therefore, in the present invention, the target area is further defined as being located at a side of the second trajectory line H near the pivoting side 21, so that the storage space is not shielded after the door body 2 is rotated to 90 °, and the user is not affected in taking and placing the articles.
It will be appreciated that the area of commissioning and the direction of commissioning may be determined by whether the gap between the door 2 and the cabinet 4 is constant when the door 2 is required to be rotated to 90 °.
Further, the method for obtaining the formula x=y is: the coordinates of the door body rotation axis on an XY coordinate system are set as (x, y), wherein x represents the abscissa of the door body rotation axis, and y represents the ordinate of the door body rotation axis. Let x+.y. It will be appreciated that the gap between the door 2 and the cabinet 4 is the first gap a when the door 2 is in the closed state as shown in fig. 2, and the gap between the door 2 and the cabinet 4 becomes the third gap a+a when the door 2 is rotated 90 ° as shown in fig. 5. If it is required that the gap between the door 2 and the cabinet 4 is not changed after the door 2 is rotated, a=0, that is, x=y is required.
Therefore, if it is necessary to make the third gap between the front wall 22 of the door 2 and the cabinet 4 equal to the first gap when the door 2 is rotated to 90 °, it is necessary to find the door rotation axis on the second trajectory line or to make the door rotation axis move on the second trajectory line H.
According to the scheme of the embodiment of the invention, the second track line H of the axle center on the hinge installation side 23 can be determined according to the formula of x=y, and the axle center is selected on the second track line H or is selected to move on the second track line H, so that the gap between the door body 2 and the cabinet 4 is ensured to be unchanged when the door body 2 rotates to 90 degrees.
At this time, the target area is defined by the first and second trajectory lines G and H together, and the boundary line of the target area includes the first and second trajectory lines G and H.
When the door body rotation axis is located in the target area, in the rotation process of the door body 2, the actual maximum door opening angle of the door body 2 is larger than the preset maximum door opening angle, and the door body 2 moves outwards when rotating to 90 degrees.
When the door body rotation axis is located on the first trajectory G as the boundary line, the actual maximum door opening angle of the door body 2 is equal to the preset maximum door opening angle during the rotation of the door body 2, and the door body 2 moves outwards when rotating to 90 °.
When the door body rotation axis is located on the second trajectory H as the boundary line, the actual maximum door opening angle of the door body 2 is greater than the preset maximum door opening angle in the rotation process of the door body 2, and the gap between the door body 2 and the cabinet 4 is unchanged when the door body 2 rotates to 90 degrees.
Further, the determining method further comprises the following steps:
fitting a third track line, wherein when the door body rotation axis is positioned on the third track line, in the process of rotating the door body 2, one end of the front wall 22 of the door body 2 positioned on the pivoting side 21 is tangent to the cabinet 4;
The target area is determined to be located on the side of the third track line remote from the box 1.
When the door body rotation axis is located at one side of the third track line away from the box body 1, a gap is formed between one end of the front wall 22 of the door body 2 located at the pivoting side 21 and the cabinet 4 in the rotation process of the door body 2, that is, it can be ensured that the door body 2 does not interfere with the cabinet 4 in the rotation process. Compared with the mode of determining the proper door body rotation axis manually and continuously according to experience in the prior art, the invention can be used for debugging in a determined target area or on the boundary line of the target area, and can ensure that the cabinet 4 is not interfered in any way during the debugging, thereby avoiding the phenomenon of repeatedly interfering the cabinet 4 in the debugging process and further increasing the debugging time.
Further, the "fitting the third trace line" specifically includes the following steps:
an XY coordinate system is constructed by taking a first intersection line of the front wall 22 of the door body 2 and the hinge mounting side 23 of the door body 2 in a closed state as an X axis, a second intersection line of the pivot side 21 of the door body 2 and the hinge mounting side 23 of the door body 2 in a closed state as a Y axis, and an intersection point of the X axis and the Y axis as an origin O;
According to the formula x= (y) 2 -A 2 ) 2A in the XY coordinate systemThe first trajectory line is drawn, wherein a represents a first gap between the pivoting side 21 of the door body 2 and the cabinet 4 when the door body 2 is in the closed state, as shown in fig. 2.
It will be appreciated that the origin mentioned above is that the front wall 22 of the door body 2 is located at one end of the pivoting side 21.
Further, formula x= (y) 2 -A 2 ) The range of y in/2A is: and y is more than or equal to 0 and less than or equal to T, wherein T represents the thickness value of the door body. So that the determined target area is located within the thickness value range of the door body 2 when in the closed state. Of course, the invention is not limited thereto, and in the embodiment in which the door body rotation axis is disposed outside the door body, the value range of y may be adaptively enlarged, for example, -T/2 is equal to or greater than y and equal to or less than T; or the range of y may be set so that the target area is located on the hinge mounting side 23 of the door body 2 in the closed state, so as to facilitate the setting of the hinge shaft.

the target area is located on the side of the fourth track line close to the pivoting side 21.
When the door body rotation axis is positioned at one side of the fourth track line near the pivoting side 21, a gap is formed between one end of the door body 2, which is positioned at the pivoting side 21, and the case 1, so that when the door body rotation axis is positioned at one side of the fourth track line near the pivoting side 21 or on the fourth track line, during the rotation of the door body 2, the rear wall of the door body 2 is positioned between one end of the pivoting side 21 and the case 1 without interference.
Further, the fitting of the fourth track line specifically includes the following steps:
an XY coordinate system is constructed by taking a first intersection line of the front wall 22 of the door body 2 and the hinge mounting side 23 of the door body 2 in a closed state as an X axis, a second intersection line of the pivot side 21 of the door body 2 and the hinge mounting side 23 of the door body 2 in a closed state as a Y axis, and an intersection point of the X axis and the Y axis as an origin O;
According to the formula y=t- (x) 2 -B 2 ) and/2B drawing the fourth track line in the XY coordinate system, wherein B represents a second gap between the door body and the box body when the door body is in a closed state, and T represents a thickness value of the door body.
Further, the formula y=t- (x) 2 -B 2 ) In the range of x in the formula/2B, x is more than or equal to 0 and less than or equal to L, wherein L represents the width value of the door body. So that the determined target area is located in the width value range of the door body when the door body is in the closed state. Of course, the present invention is not limited to this, and the door bodyIn the embodiment in which the rotation axis is disposed outside the door body, the value range of x may be adaptively widened.
Specifically, as shown in fig. 2, the hinge mounting side 23 of the door body 2 includes four sides, which are a front side, a rear side, a left side and a right side, wherein the front side is a side where an X axis is located, the right side is a side where a Y axis is located, an intersection point of the front side and the right side is an origin, and an intersection point of the rear side and the right side is defined as an N point.
It will be appreciated that the N point is located at one end of the rear wall of the door body 2 at the pivot side 21.
Wherein, formula y=t- (x) 2 -B 2 ) The method for obtaining the/2B is as follows: the coordinates of the door body rotation axis on an XY coordinate system are set as (x, y), wherein x represents the abscissa of the door body rotation axis, and y represents the ordinate of the door body rotation axis. As shown in fig. 7, it is assumed that the distance from the door rotation axis of the door 2 to the N point is R 2 And the distance from the axis to the rear is C, the radius of the N point around the axis (x, y) of the door body 2 is R during the rotation process 2 In order to avoid the interference between the door 2 and the case 1, it is necessary to ensure that the N point does not interfere with the case 1, so that the following condition is satisfied: r is R 2 -c.ltoreq.b, y=t-C and x 2 +C 2 ＝R 2 2 R is taken 2 -c=b, then scaled to obtain: this can be achieved by: x is x 2 +C 2 ＝(C+B) 2 The decomposition formula can be obtained: c= (x 2 -B 2 ) and/2B, substituting it into y=t-C to obtain the formula y=t- (x) 2 -B 2 )/2B。
It will be appreciated that at R 2 When c=b, during the rotation of the door 2, the N point on the door 2 is tangent to the box 1.
Assuming that the thickness value T and the second gap B of the door body 2 are fixed values, then y=t- (x) according to the formula 2 -B 2 ) The range 0.ltoreq.x.ltoreq.L for/2B and x may be plotted as a fourth trace F shown in FIG. 7. If the center of the circle is each point in the fourth track line F, the distance from the fourth track line F to the point N is taken as the radius, the circle passing through the point N is tangential to the box body 1, namely, when the rotation axis of the door body is positioned on the fourth track line F, the door body 2 rotatesThe N point on the door body 2 is tangent to the box body 1. If the center of the circle is at a certain point on the side of the fourth track line F near the pivoting side 21, a gap is formed between the circle passing through the N point and the box 1, that is, when the door rotation axis is at the side of the fourth track line F near the pivoting side 21, a gap is formed between the N point and the box 1 during the rotation of the door 2. If the center of the circle is at a certain point on the side of the fourth track line F away from the pivoting side 21, the circle passing through the N point will overlap with the case 1, that is, when the axis of rotation of the door body is at the side of the fourth track line F away from the pivoting side 21, there is interference between the N point and the case 1 during the rotation of the door body 2. Thus, the target area is further defined as being located on the side of the fourth trajectory line near the pivoting side 21, so that there is no interference between the door 2 and the case 1 during the rotation of the door 2.
As shown in fig. 7, when the target area defined by the first track line G and the second track line H is located within the target area defined by the fourth track line F, and the target area defined by the first track line G and the second track line H is located within the target area defined by the third track line E, that is, when the door rotation axis is located within the target area defined by the first track line G and the second track line H or the boundary line of the first track line G, the second track line H, and the third track line E together or on the boundary line of the cover target area, the door 2 can be rotated without interfering with the cabinet 1 and the cabinet 4, and the actual maximum opening angle of the door 2 is not smaller than the preset maximum opening angle, and the door 2 does not move inward when being opened to 90 °. Therefore, the fourth trajectory line F need not be considered after the target area defined by the first trajectory line G and the second trajectory line H has been defined.
Based on the above, the fourth trajectory line F may individually define the target area together with the first trajectory line G, and in this case, the boundary line of the target area includes the first trajectory line G and the fourth trajectory line F. When the door body 2 is located in the target area or on the boundary line of the target area, the actual maximum opening angle of the door body 2 is not smaller than the preset maximum opening angle, and meanwhile, interference between the door body 2 and the box body 1 is not generated in the rotation process of the door body 2.
Alternatively, the fourth track line F may define the target area together with the first track line G and the third track line E, and the boundary line of the target area includes the fourth track line F, the first track line G and the third track line E. When the door body 2 is located in the target area or on the boundary line of the target area, the actual maximum opening angle of the door body 2 is not smaller than the preset maximum opening angle, and meanwhile, interference between the door body 2 and the cabinet 1 and the cabinet 4 cannot be generated in the rotation process of the door body 2.
In the process of rotating the door body 2, the door body rotation axis is always located in the target area defined by the first track line and the second track line, so that the position of the door body rotation axis can be ensured to enable the door body 2 to not interfere with the cabinet 4 or the box 1 in the process of rotating. Compared with the mode of determining the proper door body rotation axis manually and continuously according to experience in the prior art, the invention can be used for debugging in a determined target area, and can ensure that the cabinet 4 and the box body 1 are not interfered in any way during debugging, thereby avoiding the phenomenon that the cabinet 4 and/or the box body 1 are interfered repeatedly during the debugging process so as to increase the debugging time.
Further, referring to fig. 1-2, the invention further provides an embedded refrigerator embedded in the cabinet 4. The embedded refrigerator comprises a refrigerator body 1 and a door body 2 which is rotationally connected with the refrigerator body 1 through a hinge 3, wherein the door body 2 rotates around a door body rotation axis in the process of opening and closing the door body 2. The door body is arranged in the target area or on the boundary line of the target area through the rotation axis center. The method for determining the target area is determined by the method for determining the position of the rotation axis of the door body, and will not be described in detail herein.
Specifically, the door body rotation axis may be a physical axis or a virtual axis. For example, when the hinge 3 is a single-axis hinge, the rotation axis of the door body is the axis of the rotation shaft in the single-axis hinge, that is, the solid axis. When the hinge 3 is a multi-axis hinge, the rotation axis of the door body is a virtual axis defined by multiple axes in the multi-axis hinge.
Next, taking the door rotation axis as an example, a method for determining the door rotation axis of the embedded refrigerator in the embodiments under specific requirements will be described.
First embodiment:
As shown in fig. 7, a line segment between an intersection point P1 defining the first trajectory G and the second trajectory H and the origin is a first line segment. And comprehensively considering, finally determining the rotation axis of the door body as a certain fixed point on the first line segment, or moving the rotation axis of the door body on the first line segment. At this time, the actual maximum opening angle of the door body 2 is not smaller than the preset maximum opening angle, and meanwhile, in the rotation process of the door body 2, interference between the door body 2 and the box body 1 and the cabinet 4 cannot be generated, and after the door body 2 is opened to 90 degrees, the door body cannot move inwards.
In a specific embodiment, the coordinates of the point P1 are (-5.46,5.46) in a specific embodiment, the diameter of the hinge shaft is set to be greater than or equal to 6mm in consideration of the diameter strength requirement of the hinge shaft, the installation of the hinge shaft on the door body 2 is considered, the point P1 is finally selected as the axis point, the door body 2 does not interfere with the cabinet 4 and the box body 1 in the process of rotating around the point P1, the maximum door opening angle is 120 °, and meanwhile, the door body 2 does not move inwards when being opened to 90 °.
Second embodiment:
the present embodiment differs from the first embodiment in that: as shown in fig. 8, the door hinge device 3 includes an upper hinge device 33 and a lower hinge device 34. The upper hinge device 33 and the lower hinge device 34 each have a hinge base 31 and a hinge shaft 32. In the following, the upper hinge device 33 is described as an example, and those skilled in the art will recognize that the lower hinge device 34 may be designed according to the mounting form of the upper hinge device 33 on the door 2 and the cabinet 1.
The front wall 22 of the door body 2 is higher than the hinge 3, so as to achieve the purpose of hiding the hinge 3. The whole appearance effect of the embedded refrigerator is facilitated.
Specifically, the top side (i.e., the hinge mounting side 23) of the door 2 is located higher than the top side of the case 1, and the hinge mounting side 23 of the top side of the door 2 has a recess 231. The hinge base 31 of the upper hinge device 33 spans the top side of the case 1 and the recess 231 of the door 2 to hide the upper door hinge device 3 from the rear side of the door 2.
Referring to fig. 8, the recess 231 penetrates the pivoting side 21, the upper hinge mounting side 23 and the rear side of the door body 2, that is, the recess 231 does not penetrate the front side 22 of the door body 2, and the recess 231 is not visible when the refrigerator is viewed from the front when the door body 2 is in the closed state, so that the upper door body hinge device 3 is not visible, and the upper door body hinge device 3 is hidden in the recess 231, thereby ensuring the aesthetic appearance of the door body 2.
The hinge seat 31 of the upper hinge device 33 may be constructed in a rectangular shape, one long side of which is aligned with the top side outer edge of the cabinet 1 and also aligned with the top side outer edge of the door 2 when the door 2 is in the closed state. It will be appreciated that, since the recess 231 of the door body 2 does not penetrate the front side 22 of the door body 2, the hinge seat 31 is located at the side of the pivoting side 23 and has a relief portion 311 as shown in fig. 9, and the relief portion 311 can be relieved from the front wall 22 of the door body 2 when the door body 2 is opened to a large angle, so that the hinge seat 31 can be smoothly installed at the top sides of the case 1 and the door body 2.
Also, in this embodiment, in order to avoid the upper hinge device 33 from interfering with the assembly of the door body 2, it is necessary to bring the hinge shaft 32 closer to the case 1 than in the first embodiment. The hinge axis 32 is provided on a line connecting an intersection point of the third trajectory E and the second trajectory H and the intersection point P1.
In a specific example, if the actual maximum door opening angle of the door body 2 is not smaller than the preset maximum door opening angle, the coordinate of the rotation axis of the door body may be selected to be (-11.59,9).
Third embodiment:
the third embodiment of the present invention differs from the first embodiment in that: the door body 2 is a glass door body. The glass door body is more scratch-resistant, has various colors, and can be matched with furniture and the like at will.
Because the front wall 22 of the glass door body is a glass panel with a certain thickness, the door body plastic decorative strip for fixing the glass door body also needs to have a certain wall thickness, and an adhesive gap of adhesive tape or hot melt adhesive is also needed to be arranged between the door body plastic decorative strip and the glass panel. Thus, for a glass door, the hinge axis needs to be a large distance from the front wall 22 of the door 2. At this time, the position of the door rotation axis may be determined in an overlapping region from the side of the third trajectory E away from the case 1, the side of the fourth trajectory F toward the pivoting side 21, the side of the first trajectory G away from the pivoting side 21, the side of the second trajectory H away from the pivoting side 21, or on the first trajectory G in the overlapping region, for example, the coordinates of the door rotation axis may be selected to be (-15, 11).
In summary, according to the method for determining the position of the door body rotation axis of the present invention, the target area of the door body rotation axis can be determined, so that debugging can be performed in the determined target area, and it can be ensured that the actual maximum door opening angle of the door body is not less than the preset maximum door opening angle. Compared with the mode of determining the proper door body rotation axis by manually and continuously debugging according to experience in the prior art, the invention can determine the debugging area and the debugging direction according to the needs, thereby avoiding the phenomenon that the door cannot be opened to the preset maximum door opening angle repeatedly in the debugging process and further increasing the debugging time.
It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
