DETAILED DESCRIPTION

[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "inside", "outside", etc. used in the present invention to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred devices and elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0029] like Figure 2 , Figure 3 As shown, a push armrest switch assembly of a preferred embodiment of the utility model comprises a housing 1, a lock tongue 4, a buffer 5 and an unlocking member that is pressed vertically along the armrest. For the convenience of description, the length direction of the housing 1 is defined as the first direction X. Specifically, in this embodiment, the lock tongue 4 is rotatably connected to the housing 1. In order to facilitate the unlocking and locking of the armrest, a return spring 6 corresponding to the position of the lock tongue 4 and having the same number is provided on the housing 1, wherein one end of the return spring 6 is fixed to the housing 1 and the other end is fixed to the lock tongue 4. At the same time, the unlocking member is slidably connected to the housing 1, and the unlocking member slides downward to contact the lock tongue 4, that is, when the unlocking member is pressed, the unlocking member slides downward to press the lock tongue 4, thereby driving the lock tongue 4 to rotate and unlock. In order to avoid collision between the unlocking member and the housing 1 when unlocking, the buffer 5 is arranged in the sliding direction of the unlocking member and is installed on the housing 1. When the unlocking member is pressed, the unlocking member slides downward, and the unlocking member presses the lock tongue 4 to rotate and unlock, and contacts the buffer 5, so as to avoid collision between the unlocking member and the lock tongue 4 and abnormal sound. When the unlocking piece is released, the locking tongue 4 rotates to the locked position under the elastic force of the return spring 6, and the unlocking piece moves upward to the initial position, that is, the armrest is in the closed state.

[0030] In addition, in the prior art, the unlocking member generally needs to be reset by a spring after being pressed, but the spring is not provided with a corresponding sound-absorbing sponge, and the spring is easily elastically deformed and produces abnormal noise when pressed. Therefore, specifically, in this embodiment, the unlocking member abuts against the lock tongue during the process from the locked position to the unlocked position. Therefore, after the unlocking member is released, the unlocking member can slide back to the position before being pressed under the drive of the lock tongue when the return spring drives the lock tongue to rotate to the locked position. In this way, there is no need to set a spring inside the unlocking member to achieve reset, which reduces the number of springs, reduces the possibility of abnormal noise caused by the spring when it is deformed, and helps to simplify the structure and reduce manufacturing costs.

[0031] Further, in order to facilitate the installation of the buffer member 5, refer to Figure 4 , Figure 5, a snap-in hole 11 for installing the buffer 5 is provided on the shell 1. Furthermore, in order to prevent the buffer 5 from falling off after installation, in the present embodiment, the buffer 5 includes a limiting portion 52, a snap-in portion 51 and a tapered guide portion 53 which are connected in sequence. Among them, the snap-in portion 51 is located in the snap-in hole 11. Furthermore, in order to ensure that the buffer 5 has a certain structural strength, the length of the snap-in portion 51 along the axial direction of the snap-in hole is L1mm, and L1≥0.5mm. In order to axially limit the snap-in portion 51 in the snap-in hole 11, the limiting portion 51 abuts against the end face of one axial end of the snap-in hole 11, and the tapered guide portion 53 abuts against the end face of the other axial end of the snap-in hole 11, and the diameter of the tapered guide portion 53 gradually increases in the direction approaching the snap-in portion 51. In this way, the buffer 5 is prevented from falling off from the snap-in hole 11, and the structure is stable and reliable. In the present embodiment, the tapered guide portion 53 is used for inserting into the snap-in hole 11 for guidance, which is convenient for installation. In the present embodiment, the axial length of the tapered guide portion 53 is greater than or equal to 3 mm. Furthermore, the buffer 5 is made of a flexible material. In the present embodiment, the buffer 5 is made of EPDM material, which has excellent aging resistance and good impact resistance and is not easy to be damaged. Furthermore, in order to reduce the weight of the buffer 5, relieve stress, and improve the strength and durability of the buffer 5, a blind hole 54 is opened in the middle of the buffer 5. Specifically, a blind hole 54 is vertically opened on the top surface of the limit portion 51, and the blind hole 54 extends at least to the tapered guide portion 53.

[0032] Further, in order to facilitate the design of the tapered guide portion 53, in the present embodiment, the tapered guide portion 53 includes a tapered limiting segment 531 and a straight segment 532, and the maximum diameter of the straight segment 532 is less than or equal to the minimum diameter of the tapered limiting segment 531. Among them, the tapered limiting segment 531 is connected to the clamping portion 51, and the straight segment 532 is located below the tapered limiting segment 531. The straight segment 532 is used for rough positioning during installation, and the tapered limiting segment 531 is used for fine positioning during installation. Further, in order to facilitate the insertion of the tapered limiting segment 531 into the clamping hole, the angle between the generatrix of the tapered limiting segment 531 and the axis is in the range of 20°-30°. Preferably, in the present embodiment, the angle between the generatrix of the tapered limiting segment 531 and the axis is 24°.

[0033] Further, in order to facilitate the design of the lock tongue 4 structure and prevent the lock tongue 4 and the housing 1 from slipping when rotating, refer to Figure 6 , Figure 7In this embodiment, the lock tongue 4 includes a mounting plate 41, a lock tongue body 42, and a rotating shaft 43, wherein the lock tongue body 42 is provided on the mounting plate 41, and the mounting plate 41 is used to connect with the end of the return spring 6, so that the return spring 6 can drive the lock tongue 4 to rotate as a whole. At the same time, a pressing portion 21 corresponding to the position of the mounting plate 41 is also provided on the lock body 2, that is, when the lock body 2 slides downward, the pressing portion 21 can always be in contact with the mounting plate 41, thereby causing the lock tongue 4 to rotate as a whole. Specifically, the two side walls of the bolt body 42 partially extend outward to form a rotating shaft 43, and the housing 1 is provided with mounting holes 12 corresponding to the position of the rotating shaft 43 and the same number. In order to facilitate the installation of the rotating shaft 43, an opening 121 is provided on the side wall of the mounting hole 12, and an axis flattening position 431 corresponding to the opening 121 is provided at the end of the rotating shaft 43. When the axis flattening position 431 is pushed into the mounting hole 12 facing the opening 121, the rotating shaft 43 rotates due to the elastic force of the return spring 6. At this time, the axis flattening position 431 rotates a certain angle to block the opening 121, thereby reducing the risk of the rotating shaft 43 slipping out of the mounting hole 12 after installation. The structure is stable and reliable, and the installation is convenient. Further, in order to make the unlocking member more stable when moving upward to the initial position, in this embodiment, the bolt 4 is two and is spaced apart along the first direction X, and the bolt 4 is rotatably connected to the housing 1.

[0034] Furthermore, in this embodiment, in order to facilitate the design of the unlocking member, the unlocking member includes a lock body 2 and a button 3 that are fixedly connected. The button 3 is arranged above the lock body 2. The lock body 2 and the housing 1 are slidably connected. In order to limit the sliding position of the lock body 2, refer to Figure 8 A limiting groove 13 for installing the lock body 2 is provided on the housing 1. At the same time, in order to further improve the accuracy of the lock body 2 when sliding up and down, a guide column 14 is provided in the middle of the limiting groove 13 along the vertical direction, and a guide hole corresponding to the position of the guide column 14 is provided on the lock body 2. A clearance fit is adopted between the guide column 14 and the guide hole. In order to improve the limiting accuracy, in this embodiment, the installation clearance between the guide column 14 and the guide hole is less than or equal to 0.1 mm, which can be adjusted accordingly according to actual needs.

[0035] Furthermore, in order to facilitate the unlocking member to contact and limit the position with the buffer member 5 when sliding downward, and to avoid the unlocking member and the housing from colliding, in this embodiment, a buffer member 5 is provided on the top surface of the housing 1, and a limiting boss 31 is provided at the bottom of the button 3, and the limiting boss 31 is located directly above the buffer member 5. When the button 3 is pressed, the lock body 2 can move synchronously with the button 3. The lock body 2 and the housing 1 are slidably connected, and the lock body 2 slides downward to contact the lock tongue 4, that is, when the button 3 is pressed, the lock body 2 slides downward to press the lock tongue 4, and then drives the lock tongue 4 to rotate and unlock. In order to avoid the lock body 2 and the lock tongue 4 from colliding when they contact, a buffer block 5 is provided on the top of the housing 1, and a limiting boss 31 is provided at the bottom of the button 3, and the limiting boss 31 is located directly above the buffer block 5. When the button 3 is pressed, the button 3 and the lock body 2 slide downward, and the lock body 2 presses the lock tongue 4 to rotate and unlock, and the limiting boss 31 contacts the buffer block 5, avoiding the lock body 2 and the lock tongue 4 from colliding and making abnormal noise.

[0036] The working process of the utility model is as follows: when the button 3 is pressed, the button 3 and the lock body 2 slide downward, the lock body 2 presses the lock tongue 4 to rotate and unlock, and the limiting boss 31 contacts the buffer 5 to prevent the lock body 2 and the lock tongue 4 from colliding and making abnormal noise. When the button 3 is released, the lock tongue 4 rotates to the locked position under the elastic force of the return spring 6, and the button 3 and the lock body 2 move upward to the initial position.

[0037] In summary, the present invention provides a push armrest switch assembly, including a housing 1, a locking tongue 4, a buffer 5 and an unlocking member. After the push armrest switch assembly is installed, refer to Fig. 9 , the unlocking piece is in the field of vision when pressed, which is convenient for operation. A buffer 5 is provided, and the unlocking piece slides downward to press the lock tongue 4 to rotate and unlock. The unlocking piece contacts the buffer to avoid the collision between the unlocking piece and the housing 1 to produce abnormal noise, thereby improving the user's perception experience and improving the durability of the push-armrest switch assembly, which has a long service life. In addition, there is no need to set a spring inside the unlocking piece to avoid abnormal noise caused by elastic deformation of the spring when the unlocking piece is pressed, thereby simplifying the structure.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention.
