[0034] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below with specific embodiments:

[0035] Please refer to Figures 1 to 9 , which is a push-button hand controller 10 according to an embodiment of the present invention, including a housing 100, a circuit board 200 and a plurality of buttons 300. One end of the housing 100 is connected to the electric lifting table 20. The circuit board 200 is located inside the housing 100. The plurality of buttons 300 are fixedly installed on the outer surface of the housing 100. A plurality of control buttons 210 are provided on the circuit board 200. Each button 300 is electrically connected to the circuit board 200 through the corresponding control button 210. A plurality of through holes 101 are formed on the outer surface of the housing 100. Each through hole 101 is located below the corresponding button 300. A clamping protrusion 102 is provided on the inner surface of the housing 100 along one side of the through hole 101. A plurality of buckle members 310 are provided on one side of each button 300 facing the housing 100. The buckle members 310 are arranged facing the outside of the corresponding button 300. The clamping protrusion 102 is located outside the buckle members 310. The buckle members 310 are clamped with the clamping protrusion 102 through the through holes 101.

[0036] In this embodiment, the buckle member 310 of the button 300 is pressed into the housing 100 along the corresponding through hole 101, and is clamped with the clamping protrusion 102, so that the button 300 is fixed on the surface of the housing 100. In this way, the button 300 only needs to be pressed to complete the installation, which simplifies the installation structure and improves the installation efficiency. At the same time, during use, the clamping protrusion 102 plays a role in limiting, so that the buckle member 310 cannot escape from the through hole 101, thus ensuring the stability of the installation of the button 300.

[0037] As Figures 1 to 6 shown, in one embodiment, a plurality of guide posts 320 are further formed on one side of each button 300 facing the housing 100. At least one side of each buckle member 310 is provided with a guide post 320. The housing 100 is provided with a plurality of guide holes 103, and the guide posts 320 are inserted into the corresponding guide holes 103. It can be understood that through the cooperation of the guide posts 320 and the guide holes 103, the button 300 is easier to align during assembly, improving the assembly efficiency; at the same time, the guide posts 320 can prevent the button 300 from shaking or shifting during use.

[0038] Further, in this embodiment, each button 300 is provided with two buckle members 310. The two buckle members 310 are located on both sides of the button 300. Guide posts 320 are formed on both sides of each buckle member 310, and the guide holes 103 communicate with the through holes 101. The double buckle members 310 make the installation of the button 300 more stable. The guide posts 320 are arranged on both sides, and the guide holes 103 and the through holes 101 communicate to form a square hole, so that the assembly difficulty of the button 300 can be reduced.

[0039] As Figure 6 shown, in one embodiment, a reinforcing block 311 is provided on the side of the buckle member 310 facing the inner side of the button 300. It can be understood that the reinforcing block 311 improves the structural strength of the buckle member 310, preventing the buckle member 310 from being damaged due to extrusion when disassembling the button 300; at the same time, the reinforcing block 311 can also improve the connection stability between the buckle member 310 and the clamping protrusion 102, preventing the button 300 from loosening or falling off during use.

[0040] Further, in this embodiment, the button 300, the buckle member 310 and the reinforcing block 311 are of an integrally formed structure. The integrally formed structure improves the structural strength of the button 300, thereby improving the durability of the button 300 and extending its service life.

[0041] As Figures 1 to 7As shown, in one embodiment, a plurality of center holes 104 are formed on the outer surface of the housing 100, and an annular protrusion 330 is formed at the center position of one side of the button 300 facing the housing 100. The annular protrusion 330 is arranged corresponding to the corresponding center hole 104, and the output end of the annular protrusion 330 and the control button 210 are both located in the center hole 104, and the output end of the control button 210 abuts against the inner wall of the annular protrusion 330. It can be understood that the annular protrusion 330 is arranged corresponding to the center hole 104, and the control button 210 and the button 300 are accurately aligned to avoid the problem of poor contact caused by assembly error. The output end of the control button 210 abuts against the inner wall of the annular protrusion 330, and clear feedback can be obtained through the control button 210 when the button 300 is pressed.

[0042] like Figures 1 to 8 As shown, in one embodiment, the circuit board 200 is provided with a plurality of fixing holes 201, and the outer surface of the housing 100 is provided with a plurality of through holes 105, the through holes 105 and the through holes 101 are arranged perpendicular to each other, and the plurality of fixing holes 201 and the plurality of through holes 105 are arranged one by one, and the button-type hand controller 10 further includes an auxiliary elastic member 400, one end of which is fixedly mounted on the fixing hole 201, and the auxiliary elastic member 400 abuts against the corresponding button 300 through the through hole 105. It can be understood that the auxiliary elastic member 400 is elastic, so that the button 300 can rebound to the initial position after being pressed, thereby improving the feel of the button 300.

[0043] Specifically, in this embodiment, the auxiliary elastic member 400 is a silicone auxiliary elastic member, which is round and uniform in size. There is no need to distinguish them during assembly, and only the installation end needs to be inserted into the fixing hole 201. The assembly is simple and efficient.

[0044] Furthermore, each button 300 corresponds to two auxiliary elastic members 400, and the two auxiliary elastic members 400 are symmetrically arranged on the button 300. This can prevent the button 300 from tilting or rising due to the different distances between the two sides of the button 300 during pressing or rebounding, thereby further improving the feel of the button 300.

[0045] like Figure 1 , Figures 5 to 8 As shown, in one embodiment, a plurality of abutment protrusions 340 are formed on one side of each key 300 facing the housing 100, and the auxiliary elastic member 400 abuts against the abutment protrusions 340 through the through hole 105. It can be understood that the auxiliary elastic member 400 abuts against the abutment protrusions 340 through the through hole 105, which reduces the shaking or deviation of the key 300 and provides better feedback.

[0046] Further, a connecting portion 350 is formed between the abutting protrusion 340 and the annular protrusion 330. A connecting groove 106 is formed between the central hole 104 and the through hole 105. The connecting groove 106 communicates with the central hole 104 and the through hole 105, and the connecting portion 350 is located in the connecting groove 106. The cooperation between the connecting portion 350 and the connecting groove 106 enhances the connection stability between the button 300 and the housing 100, and prevents the button 300 from shaking or shifting during use. Further, the connecting groove 106 limits the button 300, preventing the button 300 from damaging other components due to excessive pressing during pressing.

[0047] Specifically, in this embodiment, the abutting protrusion 340, the annular protrusion 330 and the connecting portion 350 are of an integrally formed structure.

[0048] As Figure 1 、 Figure 4 shown, in one embodiment, the housing 100 includes an upper housing 110 and a lower housing 120. The upper housing 110 and the lower housing 120 are fixedly connected. A plurality of buttons 300 are fixedly installed on the outer upper surface of the upper housing 110. A plurality of first avoidance holes 1101 are formed at the connection end of the upper housing 110 and the electric lifting table 20. The lower housing 120 is formed with a plurality of second avoidance holes 1201 and a plurality of avoidance grooves 1202. Each avoidance groove 1202 communicates with the corresponding second avoidance hole 1201 and the first avoidance hole 1101. A fixing member (not shown in the figure) of the electric lifting table 20 fixes the button-type remote controller 10 to the electric lifting table 20 through the corresponding first avoidance hole 1101 and the second avoidance hole 1201 and abuts against the bottom of the corresponding avoidance groove 1202. It can be understood that there is no need to additionally provide other installation structures such as a mounting plate. The fixing member is hidden in the avoidance groove 1202, making the appearance of the button-type remote controller 10 more concise.

[0049] Further, the housing 100 is of an obtuse-angled bending structure, which is convenient for operation.

[0050] Specifically, in this embodiment, the upper housing 110 and the lower housing 120 are fixedly connected by screws and buckles.

[0051] As Figure 3 、 Figure 8 and Figure 9As shown, in one embodiment, the upper housing 110 is formed with a plurality of connection holes 1102. Both ends of the circuit board 200 are provided with a plurality of mounting holes 202. The push-button hand controller 10 further includes a plurality of fixing gaskets 500 and a plurality of connecting members (not shown in the figure). The circuit board 200 is fixedly connected to the upper housing 110 through the connecting members. The connecting members sequentially pass through the fixing gaskets 500, the mounting holes 202, and the connection holes 1102. It can be understood that the fixing gasket 500 can increase the contact area between the screw and the circuit board 200, thereby increasing the friction force, preventing loosening, and at the same time dispersing the pressure to avoid damage to the circuit board 200 caused by excessive local pressure. Further, the gasket can prevent the screw from directly contacting the circuit board 200 and reduce the wear or damage of the circuit board 200.

[0052] Specifically, in this embodiment, the fixing gasket 500 is a plastic structural member and has a unified size, so there is no need to distinguish during assembly, which improves the assembly efficiency.

[0053] As Figure 1 and Figure 7 shown, in one embodiment, one end of the circuit board 200 is provided with a display 600, and one end of the surface of the housing 100 is provided with a display area 130 corresponding to the display 600. Specifically, in this embodiment, the display 600 displays the current state of the electric lifting table 20, which is convenient for understanding the current situation and adjusting the operation.

[0054] As Figure 10 shown, the present disclosure also provides an electric lifting table 20, which includes a table board 21, a liftable table frame 22, a power assembly (not shown in the figure), a fixing member, and the push-button hand controller 10 according to any one of the above embodiments.

[0055] In this embodiment, the electric lifting table 20 controls the power assembly through the push-button hand controller 10 to drive the liftable table frame 21 to perform corresponding actions and adjust to a specified state. The buttons 300 of the push-button hand controller 10 are simply and stably assembled. At the same time, the feedback of the buttons 300 is clear and the feel is good.

[0056] Compared with the prior art, the present disclosure has at least the following advantages:

[0057] Press the buckle of the button into the housing along the corresponding through hole, and the button is fixed to the surface of the housing by the engagement of the buckle and the engaging protrusion. In this way, the button only needs to be pressed to complete the installation, which simplifies the installation structure and improves the installation efficiency. At the same time, during use, the engaging protrusion plays a limiting role, preventing the buckle from passing through the through hole, thereby ensuring the stability of the button installation.

[0058] The above-described embodiments merely represent several implementation manners of the present disclosure. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
