具体实施方式detailed description
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限制本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。The present invention will be described in detail below with reference to specific embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural, method, or functional changes made by those of ordinary skill in the art according to these embodiments are included in the protection scope of the present invention.
在本发明具体实施方式的描述中，术语“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“底”、“内”和“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，通常以制冷设备处于正常使用状态为参照，而并不是指示所指的位置或元件必须具有特定的方位。In the description of specific embodiments of the present invention, the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "bottom", "inner" "Or" and "outer" are based on the orientation or positional relationship shown in the drawings, usually referring to the normal use of the refrigeration equipment, rather than indicating that the specified position or element must have a specific orientation .
如图1至图16，本发明提供的第一实施例，该实施例公开了门把手组件100及具有其的制冷设备400。As shown in FIGS. 1 to 16, the first embodiment provided by the present invention discloses a door handle assembly 100 and a refrigeration device 400 having the same.
参照图1至图4所示，制冷设备400包括一侧敞口设置的箱体200和封闭箱体200敞口处的门体300。门体300具有朝向箱体200敞口处的内表面、与内表面平行的外表面301及与内表面和外表面301相连的侧壁面302，助力门把手组件100嵌设于门体300的侧壁面302内。Referring to FIG. 1 to FIG. 4, the refrigeration device 400 includes a cabinet 200 with one side open and a door 300 closing the opening of the cabinet 200. The door 300 has an inner surface opening toward the box 200, an outer surface 301 parallel to the inner surface, and a side wall surface 302 connected to the inner surface and the outer surface 301. The door handle assembly 100 is embedded on the side of the door 300 In the wall 302.
助力门把手组件包括沿纵长方向延伸的把手2和定义了收容腔10的固定盒1，把手2至少部分被收容于收容腔10内。另外，助力门把手组件还包括传动件3和顶杆组件4，其中，传动件3设于固定盒1且与把手2活动配接，顶杆组件4相对于固定盒1可滑移设置，顶杆组件4包括延伸出固定盒1的顶杆41，顶杆41与箱体200相抵靠。且传动件3与顶杆组件4活动配接，把手2活动设置于固定盒1。具体到本实施例中，把手2可滑移地设置于固定盒1，当把手2相对于固定盒1可***作地滑移时，通过传动件3促使顶杆组件4滑移，以使顶杆41向远离固定盒1的方向向外移动。The power door handle assembly includes a handle 2 extending in a longitudinal direction and a fixed box 1 that defines a receiving cavity 10. The handle 2 is at least partially received in the receiving cavity 10. In addition, the power door handle assembly further includes a transmission member 3 and a jack assembly 4, wherein the transmission member 3 is provided in the fixed box 1 and movably connected with the handle 2, the jack assembly 4 is slidably disposed relative to the fixed box 1, the top The rod assembly 4 includes a jack 41 extending out of the fixed box 1, and the jack 41 abuts the box 200. Moreover, the transmission member 3 is movably mated with the jack assembly 4, and the handle 2 is movably disposed on the fixed box 1. Specifically in this embodiment, the handle 2 is slidably disposed in the fixed box 1, and when the handle 2 is operably slid relative to the fixed box 1, the jack 3 is caused to slide by the transmission member 3, so that the top The lever 41 moves outward away from the fixed box 1.
本优选实施例中，由于把手2可滑移地设置于固定盒1，只要拉动把手2 使其相对于固定盒1滑移，就能通过传动件3促使顶杆组件4滑移，以使顶杆41向远离固定盒1的方向向外移动，从而顶杆41顶压箱体200以实现助力开门。因此操作非常简单省力。另外，通过将助力门把手组件嵌设在门体300中，实现隐藏式助力开门的效果，便于用户操作，有利于提高用户体验性；这样用户通过助力门把手组件可以方便地将制冷设备的门体300打开，而且在把手2打开门体300的过程中，把手2不会与门体300的侧壁面302接触摩擦，避免了把手2的手持端和门体300的侧壁面302上产生划痕。In this preferred embodiment, since the handle 2 is slidably provided in the fixed box 1, as long as the handle 2 is pulled to slide relative to the fixed box 1, the jack assembly 4 can be caused to slide through the transmission member 3 to make the top The rod 41 moves outward away from the fixed box 1 so that the top rod 41 presses against the box 200 to help open the door. Therefore, the operation is very simple and labor-saving. In addition, by embedding the assisted door handle assembly in the door body 300, the effect of concealed assisted door opening is realized, which is convenient for the user to operate, which is beneficial to improve the user experience; in this way, the user can conveniently install the door of the refrigeration equipment through the assisted door handle assembly The body 300 is opened, and during the process that the handle 2 opens the door 300, the handle 2 will not contact and rub against the side wall surface 302 of the door body 300, avoiding scratches on the hand-held end of the handle 2 and the side wall surface 302 of the door body 300 .
为给把手2的拉动提供空间及便于操作把手2，当把手2处于未被拉动的自由状态时，把手2邻近门体300的外表面的末端突出于门体300的侧壁面302。当然，也可以设置成把手2邻近门体300的外表面的末端未突出于门体300的侧壁面302。只要设计成滑移把手2时，把手2不与门体300干涉即可。To provide space for pulling the handle 2 and to facilitate operation of the handle 2, when the handle 2 is in a free state without being pulled, the end of the handle 2 adjacent to the outer surface of the door 300 protrudes from the side wall surface 302 of the door 300. Of course, the end of the handle 2 adjacent to the outer surface of the door 300 may not be protruded from the side wall surface 302 of the door 300. As long as the handle 2 is designed to slide, the handle 2 does not interfere with the door 300.
把手2的滑移方向与纵长方向相垂直，且把手2的滑移方向与顶杆41的滑移方向成钝角。也就是说，把手2倾斜移动。该实施例中，纵长方向即制冷设备400的高度方向，顶杆41的滑移方向即制冷设备的深度方向。The sliding direction of the handle 2 is perpendicular to the longitudinal direction, and the sliding direction of the handle 2 is at an obtuse angle with the sliding direction of the jack 41. In other words, the handle 2 moves obliquely. In this embodiment, the longitudinal direction is the height direction of the refrigeration device 400, and the sliding direction of the jack 41 is the depth direction of the refrigeration device.
进一步的，固定盒1上设有引导把手2滑移的引导部，引导部定义了与纵长方向相平行的倾斜面112，且倾斜面112与顶杆41的滑移方向成钝角。以对把手2的倾斜滑移进行引导。Further, the fixed box 1 is provided with a guide portion for guiding the sliding movement of the handle 2, the guide portion defines an inclined surface 112 parallel to the longitudinal direction, and the inclined surface 112 forms an obtuse angle with the sliding direction of the jack 41. To guide the tilting and sliding of the handle 2.
具体的，把手2包括与倾斜面112相贴合的把手倾斜部23、供抓握的手持部21、及连接把手倾斜部23和手持部21的连接部25，把手倾斜部23和手持部21均与连接部25成角度设置，且把手倾斜部23和手持部21位于连接部25相对的两侧。手持部21较靠近门体300的外表面设置，当把手2被拉动时，把手2在逐渐靠近门体300的外表面的方向上和远离侧壁面302的方向上均产生一定位移。Specifically, the handle 2 includes a handle inclined portion 23 that fits with the inclined surface 112, a hand-held portion 21 for grasping, and a connecting portion 25 connecting the handle inclined portion 23 and the hand-held portion 21, the handle inclined portion 23 and the hand-held portion 21 Both are disposed at an angle to the connecting portion 25, and the handle inclined portion 23 and the hand-held portion 21 are located on opposite sides of the connecting portion 25. The hand-held portion 21 is disposed closer to the outer surface of the door body 300. When the handle 2 is pulled, the handle 2 generates a certain displacement in the direction gradually approaching the outer surface of the door body 300 and away from the side wall surface 302.
把手倾斜部23与连接部25成钝角，手持部21与连接部25大致相垂直，且手持部21至少部分位于收容腔10之外。这样，便于操作，且把手2被拉 动以产生滑移时，把手2不会与门体300干涉。The inclined portion 23 of the handle is at an obtuse angle with the connecting portion 25, the hand-held portion 21 is substantially perpendicular to the connecting portion 25, and the hand-held portion 21 is at least partially outside the receiving cavity 10. In this way, the operation is convenient, and when the handle 2 is pulled to cause slippage, the handle 2 does not interfere with the door 300.
把手2还包括在纵长方向上位于手持部21两端的定位部22，传动件3包括与定位部22活动配接且容置定位部22的固定部32。相应的，传动件3和顶杆组件4均设置为两个。The handle 2 further includes positioning portions 22 at both ends of the hand-held portion 21 in the longitudinal direction, and the transmission member 3 includes a fixing portion 32 movably engaged with the positioning portion 22 and accommodating the positioning portion 22. Correspondingly, both the transmission member 3 and the jack assembly 4 are provided in two.
把手2与传动件3之间设有弹性件5，定位部22设为具有开口的筒状结构，弹性件5被收容于定位部22内，且弹性件5的一端与定位部22相抵接，弹性件5的另一端与固定部32相抵接。具体的，弹性件5设置为压簧。另外，传动件3限制把手2脱离固定盒1。具体到本实施例中，固定部32止挡定位部22，以限制把手2脱离固定盒1。An elastic member 5 is provided between the handle 2 and the transmission member 3, and the positioning portion 22 is formed into a cylindrical structure having an opening. The elastic member 5 is accommodated in the positioning portion 22, and one end of the elastic member 5 is in contact with the positioning portion 22. The other end of the elastic member 5 is in contact with the fixing portion 32. Specifically, the elastic member 5 is provided as a compression spring. In addition, the transmission member 3 restricts the handle 2 from being separated from the fixed box 1. Specifically in this embodiment, the fixing portion 32 stops the positioning portion 22 to restrict the handle 2 from escaping from the fixing box 1.
定位部22敞口端与固定部32内壁间隔一定距离，以使得把手2被拉出时，定位部22能够通过弹性件5的弹性压缩朝向固定部32内部移动。另外，助力门把手组件100还包括设于弹性件5与固定部32之间的连接件6，具体的，连接件固定于固定部32的内壁，连接件6一端与弹性件5定位连接，另一端抵靠固定部32内壁，弹性件5套设于连接件5的外周。连接件6具有抵靠在固定部32上的头部及尺寸小于头部的尾部，弹性件5尺寸与尾部尺寸一致，从而弹性件5套设在尾部上且被头部限制，不会与连接件6脱离。The open end of the positioning portion 22 is spaced from the inner wall of the fixing portion 32 so that when the handle 2 is pulled out, the positioning portion 22 can move toward the inside of the fixing portion 32 by the elastic compression of the elastic member 5. In addition, the booster door handle assembly 100 further includes a connecting member 6 disposed between the elastic member 5 and the fixing portion 32. Specifically, the connecting member is fixed to the inner wall of the fixing portion 32, and one end of the connecting member 6 is positioned and connected to the elastic member 5, and another One end abuts against the inner wall of the fixing portion 32, and the elastic member 5 is sleeved on the outer periphery of the connecting member 5. The connecting piece 6 has a head that abuts on the fixed portion 32 and a tail that is smaller than the head, and the size of the elastic piece 5 is the same as the size of the tail, so that the elastic piece 5 is sleeved on the tail and is restricted by the head, and will not be connected to Piece 6 detached.
进一步的，传动件3绕转轴线可转动地设置于固定盒1，转轴线、纵长方向和顶杆41的滑移方向均相互垂直，传动件3具有相对的两端，其中一端与把手2相活动配接，其中另一端与顶杆组件4相配接。具体的，传动件3与顶杆组件4相抵接。当然，传动件3与顶杆组件4之间也可以采用其它配接方式。Further, the transmission member 3 is rotatably disposed on the fixed box 1 about a rotation axis, the rotation axis, the longitudinal direction and the sliding direction of the ejector 41 are perpendicular to each other, and the transmission member 3 has opposite ends, one end of which is opposite to the handle 2 Phase matching, the other end is matched with the jack assembly 4. Specifically, the transmission member 3 is in contact with the jack assembly 4. Of course, other matching methods can also be adopted between the transmission member 3 and the jack assembly 4.
当把手2***作地相对于固定盒1活动时，定位部22与固定部32在平行于转轴线的方向上产生相对移动，且固定部32与定位部22相对转动，使得传动件3相对于固定盒1转动以促使顶杆组件4滑移，以使顶杆41向远离固定盒1的方向向外移动。因此把手2只要活动较小的位移，就可使顶杆41移出一定距离以顶压箱体，使得把手活动的空间较小，不会与门体干涉。具 体到本实施例中，把手2可滑移地设置于固定盒1。当然，把手2也可以采用其它活动设置方式设置于固定盒1上。只要使定位部22和固定部32之间既产生相互直线移动，又产生相对转动，从而通过传动件3的转动，促使顶杆组件4直线移动即可。当把手2***作地相对于固定盒1倾斜滑移时，定位部22在转轴线的延伸方向上向固定部32的底壁移动，同时定位部22与固定部32之间相对转动，弹性件5被压缩，传动件3相对于固定盒1转动，以推动顶杆组件4相对于固定盒1直线移动，使顶杆41向突出于固定盒1的方向向外移动，从而顶压箱体200，实现助力开门。When the handle 2 is operatively moved relative to the fixed box 1, the positioning portion 22 and the fixing portion 32 are relatively moved in a direction parallel to the axis of rotation, and the fixing portion 32 and the positioning portion 22 are relatively rotated, so that the transmission member 3 is relative to The fixed box 1 rotates to urge the jack assembly 4 to slide, so that the jack 41 moves away from the fixed box 1. Therefore, as long as the handle 2 moves with a small displacement, the jack 41 can be moved a certain distance to press the box body, so that the space for the movement of the handle is small and will not interfere with the door body. Specifically, in this embodiment, the handle 2 is slidably provided in the fixed box 1. Of course, the handle 2 can also be arranged on the fixed box 1 by other movable setting methods. As long as the positioning portion 22 and the fixing portion 32 not only linearly move relative to each other, but also generate relative rotation, so that the rotation of the transmission member 3 can cause the jack assembly 4 to move linearly. When the handle 2 is operated to slide obliquely with respect to the fixed box 1, the positioning portion 22 moves toward the bottom wall of the fixing portion 32 in the extending direction of the rotation axis, and at the same time, the positioning portion 22 and the fixing portion 32 relatively rotate, and the elastic member 5 is compressed, the transmission member 3 rotates relative to the fixed box 1 to push the jack assembly 4 to move linearly relative to the fixed box 1, so that the jack 41 moves outward in a direction protruding from the fixed box 1, thereby pressing the box 200 , To help open the door.
当把手2***作地滑移时，把手2在沿转轴线的方向上和沿顶杆41的滑移方向上均产生一定位移。当把手2从自由状态被拉动至最终状态的过程中，手持部21逐渐远离侧壁面302并逐渐靠近门体300的外表面，但直到把手2被拉动至最终状态，把手2的手持部21也未突出于门体300的外表面。When the handle 2 is operatively slid, the handle 2 generates a certain displacement in both the direction along the rotation axis and the sliding direction of the jack 41. When the handle 2 is pulled from the free state to the final state, the hand-held portion 21 gradually moves away from the side wall surface 302 and gradually approaches the outer surface of the door 300, but until the handle 2 is pulled to the final state, the hand-held portion 21 of the handle 2 also It does not protrude from the outer surface of the door body 300.

The positioning portion 22 The fixed portion 32 can be moved along the extension direction of the rotation axis, and when the handle 2 is moved, the positioning portion 22 can drive the fixed portion 32 to move in the sliding direction of the top rod 41 in the receiving groove 114, thereby causing the transmission member 3 to rotate Since the transmission member 3 is in contact with the ejector rod assembly 4, one end of the ejector rod assembly 4 is in contact with and positioned with the abutting portion 33 to form an interlocking structure, which ultimately causes the ejector rod assembly 4 to slide relative to the fixed box 1.
参照图11至图13所示，门体300关闭设置在箱体200上，此时助力门把手组件100处于非使用状态。把手2的突出部24位于滑动槽113靠近箱体200的一端，传动件3的固定部32与把手2的定位部22在顶杆41的滑移方向上位于收容槽114靠近箱体200的一侧，且在转轴线的延伸方向上，把手2的定位部22对应收容槽114，定位部22敞口端与固定部32内壁间隔一定距离，传动件3的抵接部33位于定位槽116远离箱体200的一侧。顶推部43与箱体200抵靠。Referring to FIG. 11 to FIG. 13, the door body 300 is closed and disposed on the box body 200, and the assisted door handle assembly 100 is in a non-use state. The protruding portion 24 of the handle 2 is located at the end of the sliding groove 113 close to the box 200, and the fixing portion 32 of the transmission member 3 and the positioning portion 22 of the handle 2 are located at a position of the receiving groove 114 near the box 200 in the sliding direction of the jack 41 Side, and in the extending direction of the rotation axis, the positioning portion 22 of the handle 2 corresponds to the receiving groove 114, the open end of the positioning portion 22 is spaced a certain distance from the inner wall of the fixing portion 32, and the abutting portion 33 of the transmission member 3 is located away from the positioning groove 116 One side of the box 200. The pushing portion 43 abuts the box 200.
参照图14至图16所示，门体300与箱体200相分离，助力门把手组件100处于使用状态。即当将把手2向外拉出时，即将把手2朝向门体300的外表面的方向拉动，把手2的把手倾斜部2323通过突出部24在滑动槽113内滑动而沿着倾斜面112倾斜向外移动，使得把手2同时沿转轴线的延伸方向和顶杆41的滑移方向向外倾斜移动，此时，定位部22在固定部32上沿转轴线的延伸方向上向外移动，使弹性件5压缩变形，同时定位部22带动固定部32沿收容槽114向外移动，使传动件3相对于固定盒1转动，令抵接部33朝向靠近顶推部43方向向内移动，并推动顶杆组件4的顶推部43朝向固定盒1外部伸出，从而顶推部43推抵箱体200，并产生对门体300的反作用力，而令门体300打开，实现省力方便开门。松开把手2后，顶杆41和传动件3通过复位件7回复到非工作状态，固定部32和定位部22通过弹性件5回复到非工作状态，从而把手2也回复到非工作状态。Referring to FIGS. 14 to 16, the door body 300 is separated from the box body 200, and the door handle assembly 100 is assisted in the use state. That is, when the handle 2 is pulled out, that is, the handle 2 is pulled toward the outer surface of the door body 300, the handle inclined portion 2323 of the handle 2 slides in the sliding groove 113 through the protruding portion 24 and is inclined toward the inclined surface 112 The outward movement makes the handle 2 move obliquely outward along the extension direction of the rotation axis and the sliding direction of the jack 41 at this time, at this time, the positioning portion 22 moves outward along the extension direction of the rotation axis on the fixing portion 32, making the elasticity The member 5 is compressed and deformed, and at the same time, the positioning portion 22 drives the fixing portion 32 to move outward along the receiving groove 114, so that the transmission member 3 rotates relative to the fixed box 1, so that the contact portion 33 moves inward toward the pushing portion 43, and pushes The pushing portion 43 of the jack assembly 4 extends toward the outside of the fixed box 1, so that the pushing portion 43 pushes against the box 200 and generates a reaction force against the door body 300, so that the door body 300 is opened, saving effort and facilitating opening the door. After the handle 2 is released, the jack 41 and the transmission member 3 return to the non-working state through the reset member 7, and the fixing portion 32 and the positioning portion 22 return to the non-working state through the elastic member 5, so that the handle 2 also returns to the non-working state.
