Description

Technical Field

[0001] The present invention relates to the field of pressing panels, and in particular to a pressing panel which saves effort and has a good pressing feel. Background Art

[0002] Generally, the drive panel of the hidden water tank has two types of panels: single-row buttons and double-row buttons. After the button is pressed, a reset mechanism is required to drive the button back to its initial position. Existing reset mechanisms generally use elastic components such as shrapnel and torsion springs. The fixing points of these elastic components are placed on the panel body, and the supporting points are placed on the buttons. When the button is pressed, the fixing points of the elastic components remain unchanged, and the part between the supporting point and the fixed point begins to deform. The greater the pressing stroke, the greater the elastic deformation, and the greater the rebound resistance of the button. This results in an increase in pressing force and a poor pressing feel. Summary of the invention

[0003] To this end, the present invention provides a pressing panel that saves effort and has a good pressing feel by improving the connection structure.

[0004] To achieve the above purpose, the technical solution provided by the present invention is as follows:

[0005] A push panel comprises: a panel, a button and an elastic member, wherein the button is hinged on the panel so as to be movable relative to the panel at a hinge axis, the elastic member is fixed on the button, the elastic member has an elastic arm extending outward, the elastic arm presses the panel by its elastic force, during the stroke in which the button moves relative to the panel at the hinge axis, the elastic arm slides at a pressing position on the panel, and in an initial state when not pressed, the pressing position of the elastic arm on the panel is further away from the fixed position of the button and the elastic member than the position of the hinge axis.

[0006] Furthermore, as a preferred solution: the elastic member is a long strip of spring sheet or a long strip of elastic linear body.

[0007] Furthermore, as a more preferred solution: the elastic member is in an arched structure, with a recessed portion at its middle position, a socket with a bayonet is formed on the button, the elastic member is inserted into the bayonet, and its first end and second end are pressed against the button and the panel respectively, the recessed portion at its middle position is fixed in the socket by the elastic force of the elastic member, and the elastic section between the recessed portion of the elastic member and its second end is the elastic support arm.

[0008] Furthermore, as a more preferred solution: a guide slope is provided between the first end of the elastic member and the pressing position of the button and the socket.

[0009] Furthermore, as a more preferred solution: a limiting structure is provided at a pressing position of the first end of the elastic member on the button.

[0010] Furthermore, as a more preferred solution: the limiting structure is a protrusion extending from the button on both sides.

[0011] Furthermore, as a more preferred solution: the elastic member is a torsion spring.

[0012] Furthermore, as a more preferred solution: a fixed shaft is provided on the button, the torsion spring is fixedly sleeved on the fixed shaft, its first arm presses against the button, and its second arm presses against the panel, and the second arm of the torsion spring is the elastic arm.

[0013] Furthermore, as a more preferred solution: the elastic support arm is provided with a limiting track extending along the sliding path of the elastic support arm at the pressing position on the panel.

[0014] Furthermore, as a more preferred solution: the limiting track is a protrusion formed by extending integrally from the panel and standing on both sides.

[0015] Furthermore, as a preferred solution: the button is respectively extended with hinged pillars at two ends of the same side, and is hinged to the panel through two hinged pillars, and the elastic member is arranged between the two hinged pillars.

[0016] Furthermore, as a preferred solution: the panel has a surface and a back side opposite to the surface, the button and the elastic member are arranged on the back side of the panel, and a yield window corresponding to the button is opened on the surface of the panel.

[0017] Furthermore, as a more preferred solution: the back side of the panel also extends backward to form a blocking hook, and the button is pressed to make it swing backward to a certain angle and then press against the blocking hook, and is limited by the blocking hook.

[0018] Furthermore, as a more preferred solution: the button also has a pressing protrusion extending into the yield window.

[0019] The technical solution provided by the present invention has the following beneficial effects:

[0020] The elastic member is fixed on the movable part, that is, on the button, and the supporting point is placed on the panel body, and is arranged to be slidable and pressed. When the button is pressed, the elastic member moves with the button, and the sliding of the elastic arm of the elastic member on the panel can well offset the deformation of the elastic member, so that the elastic deformation of the elastic member is small, and the rebound resistance of the button does not change much. In this way, the pressing force changes little during the button pressing process, and compared with existing products, the panel pressing is labor-saving and the pressing feel is better.

[0031] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0032] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0033] Embodiment 1

[0034] Reference Figures 1 to 7As shown, a pressing panel provided in this embodiment includes: a panel 10, a button 20 and an elastic member 30, wherein the button 20 is hinged on the panel 10 so as to be movable relative to the panel 10 at a hinge axis 231, and the elastic member 30 is fixed on the button 20, and the elastic member 30 has an elastic arm 304 extending outward, and the elastic arm 304 presses the panel 10 by its elastic force, and during the movement of the button 20 relative to the panel 10 at the hinge axis, the elastic arm 304 slides at the pressing position of the panel 10, and in the initial state where the button 20 is not pressed, as shown in FIG. Figure 2 and Figure 3 As shown, the pressing position of the elastic arm 304 on the panel 10 (i.e., the second end 302 described below) is farther away from the fixed position of the button 20 and the elastic member 30 (i.e., the position of the holder 21 described below) than the position of the hinge shaft 231. That is, the pressing position of the elastic arm 304 on the panel 10 is located at the top, the hinge shaft 231 is located in the middle, and the fixed position of the button 20 and the elastic member 30 is at the bottom. When the button 20 is pressed, the elastic member 30 moves with the button 20, and the sliding of the elastic arm 304 of the elastic member 30 on the panel 10 can well offset the deformation of the elastic member 30, so that the elastic deformation of the elastic member 30 is small, and the rebound resistance to the button 20 does not change much. On the basis of the initial state, the button is pressed to swing backward 15°. The state after pressing is shown in the figure below. Figure 4 , Figure 5 and Figure 6 See also Figure 7 As shown, the solid line portion is the state of the elastic member 30 before being pressed, and the dotted line portion is the state after being pressed. The fixed position of the elastic member 30 moves along with the button 20, and the elastic arm 304 slides downward at the pressing position on the panel (i.e., the second end 302 described below) to offset the deformation. The elastic member 30 hardly deforms, so that the pressing force changes little during the pressing process of the button 30.

[0035] If the elastic member 30 of the present solution is fixed in accordance with the existing fixing method, that is, the elastic member 30 is fixed on the panel 10, the elastic arm 304 is pressed against the button 20, and also swings back 15°, the change of the elastic member 30 is as follows: Figure 8 As shown, the solid line part is the state before pressing, and the dotted line is the state after pressing, and the bending deformation starts from the fixed point A, and the deformation amount is large. It can be judged that compared with the existing products, this solution greatly eliminates the deformation amount of the elastic member 30, realizes the button 20 to press effortlessly, and the pressing feel is better.

[0036] Further, in this embodiment, the elastic member 30 is a long strip of spring sheet, the elastic member 30 is an arched structure, and has a recessed portion 303 at its middle position. The button 20 forms a holder 21 with a bayonet 211, and the elastic member 30 is inserted into the bayonet 211 of the holder 21, and its first end 301 and second end 302 are pressed against the button 20 and the panel 10 respectively. The recessed portion 303 at its middle position is fixedly clamped in the holder 21 by the elastic force of the elastic member 30 itself, thereby realizing the assembly of the elastic member 30. The elastic section between the recessed portion 303 of the elastic member 30 and its second end 302 is the elastic arm 304. This method can facilitate disassembly and assembly. That is, during assembly, the first end 301 of the elastic member 30 is inserted through the bayonet 211, and then the arched middle position of the elastic member 30 is pressed down to make the arched middle position pass through the bayonet 211 until the recessed portion 303 is locked in the socket 21. At this time, the first end 301 and the second end 302 are respectively pressed against the button 20 and the panel 10. The section between the first end 301 and the recessed portion 303 is a fixed section, and the section between the recessed portion 303 of the elastic member 30 and the second end 302 is an elastic section, which is also the elastic support arm 304.

[0037] The spring piece of the arched structure has a raised elastic force, which ensures the stability of the structure and facilitates assembly. When removing, the middle position of the elastic member 30 is pressed to separate the recessed portion 303 from the pressing of the holder 21, and then the elastic member 30 is pulled out to achieve removal.

[0038] More specifically, a guide slope 25 is provided between the first end 301 of the elastic member 30 and the pressing position of the button 20 and the holder 21; during insertion and assembly, the assembly can be completed under the guidance of the guide slope 25, making the assembly action smoother.

[0039] Specifically, the first end 301 of the elastic member 30 is provided with a limiting structure at the pressing position on the button 20, and more specifically, the limiting structure is a protrusion 22 formed by extending from the button 20 on both sides, which can play a good limiting role and prevent assembly deviation.

[0040] Preferably, in this embodiment, the elastic arm 304 is provided with a limiting track extending along the sliding path of the elastic arm 304 at the pressing position on the panel 10. Specifically, the limiting track is a protrusion 12 formed by extending from the panel 10 and formed on both sides. It also plays a limiting role to prevent the elastic arm 304 of the elastic member 30 from deflecting on the panel 10.

[0041] Specifically, in this embodiment, the panel 10 has a surface 101 and a back surface 102 opposite to the surface 101, the button 20 and the elastic member 30 are arranged on the back surface 102 of the panel 10, and the surface 101 of the panel 10 is provided with a yield window 11 corresponding to the button 20, and the operator presses the button 20 from the yield window 11. Of course, in other embodiments, the structure of the panel 10 and the arrangement of the button 20 are not limited to this; for example, the button 20 is exposed below the panel 10, and the operator presses the button 20 exposed below; or the button 20 is hinged to the lower bottom surface of the panel 10, and the pressing position of the elastic member 30 remains unchanged, pressing against the back of the panel 10, which can also meet the functions of pressing and returning, etc.

[0042] Furthermore, the button 20 also has a pressing protrusion 24 extending into the yield window 10, which is convenient for the operator to press. In this specific embodiment, in the initial state when not pressed, the surface of the pressing protrusion 24 is substantially flush with the surface of the panel 10, and the appearance is beautiful. Of course, in other embodiments, it is not limited to this, such as the pressing protrusion 24 can also protrude from the surface 101 of the panel 10, which is more convenient for pressing operations.

[0043] Furthermore, in this embodiment, the back side 102 of the panel 10 also extends backward to form a blocking hook 13. When the button 20 is pressed, it swings backward to a certain angle and then presses against the blocking hook 13, where it is limited by the blocking hook 13 to prevent damage to internal parts caused by excessive pressing stroke.

[0044] Furthermore, in this embodiment, the button 20 is respectively extended with hinged pillars 23 at both ends of the upper side, and is hinged to the panel 10 through the two hinged pillars 23. The elastic member 30 is arranged between the two hinged pillars 23, and the force distribution is more uniform. In addition, the hinged pillars 23 are extended at both ends of the upper side for hinged connection. When returning to the original position, the gravity of the button 20 also plays a role, and the return effect is better. Of course, in other embodiments, the hinged pillars 23 can be extended on other sides (such as the left side, the right side or even the lower side) for hinged connection. When the hinged pillars 23 are extended on the left or right side for hinged connection, the return is completely dependent on the elastic force of the elastic member 30; when the hinged pillars 23 are extended on the lower side for hinged connection, the elastic member 30 also has to overcome the gravity of the button 20, and the effect is poor.

[0045] Embodiment 2

[0046] The structure of the pressing panel provided in this embodiment is substantially the same as that of the first embodiment, except that: Fig. 9 As shown, in this embodiment, the elastic member 30 is a long elastic linear body, such as an elastic metal wire, etc. The structure and installation structure of the long elastic linear body are the same as those of the spring sheet in the first embodiment, and will not be described again.

[0047] Embodiment 3

[0048] The present embodiment provides a pressing panel, which is substantially the same in structure as the first and second embodiments, and has the same assembly structure of the panel and the button, but the difference lies in the structural shape of the elastic member and the fixing method to the button. The elastic member in this embodiment is only a part having the elastic arm in the first and second embodiments, and the elastic member is fixed to the button by bolts or rivets, and the part of the elastic arm extends outward to form the structure in the first and second embodiments.

[0049] Embodiment 4

[0050] The pressing panel provided in this embodiment has a substantially similar structure to that of the first embodiment, except that: Fig.10 As shown, in this embodiment, the elastic member 30 is a torsion spring, and a fixed shaft (not shown) is provided on the button 20. The torsion spring is fixedly sleeved on the fixed shaft, and its first arm 31 presses on the button 20, and its second arm 32 presses on the panel. The second arm 32 of the torsion spring is the elastic arm 304. The torsion spring is a commonly used elastic member in the prior art, which is easy to purchase from the market, does not need to be customized, and is easy to assemble.

[0051] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, it should be understood by those skilled in the art that various changes may be made to the present invention in form and details without departing from the spirit and scope of the present invention as defined by the appended claims, all of which are within the scope of protection of the present invention.
