[0031] Embodiment 1
[0032] Figure 1 The structure diagram of the door handle 100 of this embodiment installed on the door body 200 of the horizontal refrigerator is shown, wherein Figure 1 The middle door handle 100 is in a folded state. Figures 2 to 8 The present embodiment relates to a door handle 100, comprising a mounting seat 10, a fixing seat 20, a first guide assembly, a second guide assembly and a gripping portion 60, wherein a receiving space is formed in the fixing seat 20, the first guide assembly and the second guide assembly are received in the receiving space of the fixing seat 20, and the first guide assembly and the second guide assembly are located on the same horizontal line in the fixing seat 20 and the working principles and structures of the two are exactly the same, that is, the first guide assembly and the second guide assembly are symmetrically distributed relative to the longitudinal center line of the fixing seat 20.
[0033] The first guide assembly includes a rotating part 30, a movable part 40 and a deformable part. In this embodiment, the deformable part is a spring 50. The rotating part 30, the movable part 40 and the spring 50 are arranged in a straight line. One end of the rotating part 30 is fixedly connected to one end of the holding part 60. The rotating part 30 and the movable part 40 cooperate with the first protrusion 311 and the second protrusion 41 to enable the movable part 40 to move left and right in the accommodating space when the rotating part 30 rotates, and the spring 50 rebounds or compresses when the movable part 40 moves left and right. Similarly, the second guide assembly includes a rotating portion 30', a moving portion 40' and a spring 50', and the rotating portion 30', the moving portion 40' and the spring 50' are also arranged in a straight line, one end of the rotating portion 30' is fixedly connected to the other end of the gripping portion 60', and the rotating portion 30' and the moving portion 40' cooperate through their first protrusion and the second protrusion to enable the moving portion 40' to move left and right in the accommodation space when the rotating portion 30' rotates, and the spring 50' rebounds or compresses when the moving portion 40' moves left and right. In this embodiment, along the length of the accommodation space, the rotating portion 30, the moving portion 40, the spring 50, the spring 50', the moving portion 40' and the rotating portion 30 are arranged in a straight line. When the user grasps the gripping portion 60 to fold the door handle 100 (the angle of the door handle 100 can be defined as 0° at this time) and unfold it (the angle of the door handle 100 can be defined as 90° at this time), the rotating portions 30 and 30' are driven to rotate between 0° and 90°, so that the movable portions 40 and 40' move left and right in the accommodating space.
[0034] In alternative embodiments, the deformation portion may also be a component with other deformations.
[0035] The following is a detailed introduction taking the first guide assembly 20 as an example.
[0036] In order to facilitate the assembly of the door handle 100 and the installation on the door body 200, as Figure 3 As shown, the rotating part 30 of this embodiment includes a cam 31 and a connecting member 32. The connecting member 32 includes a plug-in portion 321 for plugging into a plug-in slot (not shown) at one end of the cam 31 and a mounting portion 322 for mounting to the gripping portion 60. When the plug-in portion 321 is plugged into the plug-in slot of the cam 31, the connecting member 32 and the cam 31 can rotate synchronously. Figure 4 and Figure 5As shown, a first protrusion 311 is protruded on the end surface of the cam 31 facing the movable part 40, and a second protrusion 41 is protruded on the end surface of the movable part 40 facing the cam 31. The second protrusion 41 has an arc-shaped outer contour. When the movable part 40 rotates, the first protrusion 311 rotates along the arc-shaped outer contour of the second protrusion 41. When the first protrusion 311 is at one end of the arc-shaped outer contour of the second protrusion 41, the door handle 100 is in a folded state. When the second protrusion 41 moves along the arc-shaped outer contour to the other end of the arc-shaped outer contour, the door handle 100 is in an unfolded state. When the door handle 100 changes from folding to unfolding or from unfolding to folding, the spring 50 is always in a compressed state, so as to ensure a tight fit between the cam 31 and the connecting member 32.
[0037] Reference again Figures 4 to 6 In order to achieve the cooperation between the cam 31 and the moving part 40, a first guide groove 43 is provided at one end of the moving part 40 close to the cam 31. Correspondingly, a guide post 313 is provided at the end of the cam 31 close to the moving part 40. The guide post 313 is inserted into the first guide groove 43. When the cam 31 rotates, the moving part 40 can only move left and right in the accommodation space. In order to prevent the moving block 40 from rotating during the movement and play a role in movement guidance, as shown in FIG. Figure 6 As shown, a second guide groove 22 is correspondingly provided on the fixed seat 20, and a guide portion 44 is correspondingly provided on the side wall of the movable portion 40. When the movable portion 40 is located in the accommodation space of the fixed seat 20, the guide portion 44 extends into the second guide groove 22. Figure 5 As shown, a spring guide post 45 is provided at one end of the moving part 40 close to the spring 50 , and the spring 50 is sleeved on the spring guide post 45 to ensure movement guidance during the compression process of the spring 50 .
[0038] In order to avoid pinching the user's hand when the door handle 100 automatically recovers from the unfolded state to the folded state when the user opens the door body 200, and to facilitate the user to open the door handle 100 from the folded state to the unfolded state, the arc-shaped outer contour of the second protrusion 41 of the movable part 40 is optimized to meet the different usage experiences of users.
[0039] like Figure 5 As shown, the second protruding portion 41 of the moving portion 40 includes a first slope 411 and a second slope 412, one end of the first slope 411 is butted against one end of the second slope 412, the first slope 411 is inclined upward and the second slope 412 is inclined downward, and the slope of the first slope 411 is smaller than the slope of the second slope 412. The grip portion 60 has a folding position perpendicular to the door body 200 (such as Figure 1 and Figure 2As shown, the door handle 100 is in a folded state) and an unfolded position parallel to the door body 200 (i.e., the door handle 100 is in an unfolded state). When the grip portion 60 is switched from the folded position to the unfolded position, the first protrusion 311 passes through the first slope 411 and the second slope 412 in sequence, and when the grip portion 60 is switched from the unfolded position to the folded position, the first protrusion 311 passes through the second slope 412 and the first slope 411 in sequence. In this way, when the gripping portion 60 is converted from the folded position to the open position, since the outer contour slope of the first slope 411 is relatively small, the user only needs a small force to realize the conversion of the door handle 100 from the folded state to the open state; and when the gripping portion 60 is converted from the open position to the folded position, since the outer contour slope of the second slope 412 is relatively large, the user needs a larger force to convert the door handle 100 from the open position to the folded position, thereby preventing the door handle 100 from rotating during the process of opening and closing the door, and at the same time, eliminating the safety hazard of pinching the hand during the process of closing the door, and realizing the door handle 100 hovering at 90°.
[0040] Of course, the second protrusion 41 may also include a first slope 411, a slope X, and a second slope 412 that are connected in sequence, wherein the first slope 411 and the second slope 412 should be inclined upward and downward respectively, and the slope of the first slope 411 is smaller than the slope of the second slope 412. The slope X is not limited to one slope, and may be a combination of multiple slopes that are connected in sequence.
[0041] In addition, in order to limit the unfolded state of the door handle 100, a limiting groove 42 is formed on the end surface of the movable part 40 close to the cam 31 and close to the end of the second slope 412. When the gripping part 60 is converted from the folded position to the unfolded position, the first protrusion 311 passes through the first slope 411 and the second slope 412 in sequence and enters the limiting groove 42, further limiting the unfolded position of the door handle 100. In this way, when the gripping part 60 is converted from the open position to the folded position, since the first protrusion 311 is located in the limiting groove 42 and the outer contour slope of the second slope 412 is larger, the user needs more force to convert the door handle 100 from the open position to the folded position, thereby avoiding the door handle 100 from rotating during the process of opening and closing the door, and at the same time, eliminating the safety hazard of pinching the hand during closing the door.
[0042] like Figure 4 As shown, a first limiting portion 312 is convexly formed on the outer side wall of the cam 31, which cooperates with the fixed seat 20 to limit the rotation range of the cam 31, that is, when the door handle 100 is in a folded state, the first limiting portion 312 abuts against a limiting surface (not shown) of the fixed seat 20, and when the door handle 100 is in an open state, the first limiting portion 312 abuts against another limiting surface (not shown) of the fixed seat 20.
[0043] like Figure 3 As shown, the mounting portion 322 of the connecting member 32 is provided with a screw mounting hole 3221 for fixing the connecting member 32 to the gripping portion 60. When installing, after the connecting member 32 is installed in the accommodation space of the fixing seat 20, the connecting member 32 is fixedly mounted to the gripping portion 60. Figure 7 As shown, a second limiting portion 323 is also formed on the connecting member 32 , which is used to limit the rotation range of the connecting member 32 driven by the holding portion 60 .
[0044] Specifically, see Figure 6 and Figure 7 The fixing seat 20 has a first limiting surface 23 and a second limiting surface 24. When the door handle 100 is in a folded state (such as Figure 7 As shown in the figure, the second limiting portion 323 of the connecting member 32 abuts against the first limiting surface 23, and when the door handle 100 is in the unfolded state, the second limiting portion 323 of the connecting member 32 abuts against the second limiting surface 24, preventing the door handle 100 from rotating to a larger angle under the action of a larger external force, and is used to limit the rotation of the door handle 100 between 0° (i.e., the door handle 100 is in the folded state) and 90° (i.e., the door handle 100 is in the unfolded state). In addition, a screw fixing hole (only the screw fixing hole 25 is marked) is provided on the fixing seat 20, for the screw to pass through the screw fixing hole 25 and the corresponding screw fixing hole 11 on the mounting seat 10 to achieve the fixed installation of the fixing seat 20 to the mounting seat 10. And still referring to Figure 6 There are three slots evenly distributed on the top of the fixing seat 20 (only the slot 21 is marked), and correspondingly, a buckle (not shown) is provided on the inner wall of the top of the mounting seat 10, and the installation of the fixing seat 20 to the mounting seat 10 is achieved through the cooperation of the buckle and the slot; and in order to facilitate the installation of the fixing seat 20 and the mounting seat 10, a guide hole 26 is also formed on the fixing seat 20, and correspondingly, a guide column (not shown) is formed on the inner wall of the mounting seat 10, and the guide column extends into the guide hole 26 to achieve the installation positioning of the fixing seat 20 to the mounting seat 10.
[0045] like Figure 8 As shown, the gripping portion 60 of this embodiment includes a first lateral portion 61, a second lateral portion 62 and a pull rod 63 connected to the bottom end of the first lateral portion 61 and the bottom end of the second lateral portion 62. The first lateral portion 61 and the second lateral portion 62 have the same structure and are used for connection with the connecting member 32 and the connecting member 32' respectively.
[0046] The structure is described by taking the first lateral portion 61 as an example. A mounting groove 611 is formed at the top of the first lateral portion 61, and a fixing hole 612 is provided thereon. The screw passes through the mounting hole 3221 on the mounting portion 322 of the connecting member 32 and the fixing hole 612 to achieve a fixed connection between the connecting member 32 and the first lateral portion 61. Similarly, a fixed connection between the connecting member 32' and the second lateral portion 62 is achieved.
[0047] When assembling the door handle 100, the following assembly method can be used: (1) Place the cam 31 of the rotating part 30 and the cam 31' of the rotating part 30' in the accommodating space of the fixed seat 20; (2) Install the springs 50 and 50' on the movable parts 40 and 40' in turn, and then install them as a whole on the cam 31 and the cam 31' of the rotating part 30' respectively; (3) Install the partially assembled fixed seat 20 on the mounting seat 10 by screws, and the mounting seat 10 is fixed to the door body 200 by screws; (4) Insert the connecting member 32 and the connecting member 32' into the insertion groove of the cam 31 and the insertion groove of the cam 31' respectively; (5) Fix the connecting member 32 and the connecting member 32' to the first lateral portion 61 and the second lateral portion 62 of the gripping portion 60 respectively.
[0048] When the user is not in use, the door handle 100 can be folded to avoid the user from bumping into it when walking, and the space occupied is reduced, which improves the user experience; and during transportation, the same space can be used to increase the packing volume. When the door body 200 is to be opened, the pull rod 63 is pulled to unfold the door handle 100 to 90 degrees, so that the door handle 100 is parallel to the door body 200, and the force arm of the door handle 100 is increased to achieve the effect of labor-saving door opening; the first protrusion 311 cooperates with the first slope 411 and the second slope 412, so that the user only needs a small force to realize the conversion of the door handle 100 from the folded state to the unfolded state, further saving effort to open the door, and the user needs a large force to convert the door handle 100 from the unfolded state to the folded state, avoiding the limit of the door handle 100 during the process of opening and closing the door, achieving 90° hovering, and at the same time eliminating the safety hazard of the door handle 100 being folded and pinching the hand during the door closing process.

Figures 2 to 8 As described above, no further elaboration is given here.
[0051] The front edge of the door body 200 is an arc-shaped edge. Correspondingly, the shape of the portion of the mounting base 10 that contacts the door body 200 is also an arc-shaped, which facilitates the tight installation of the door handle 100 and the front edge of the door body 200.
[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein by equivalents.
