Description

Technical Field

[0001] The present application relates to the field of key technology, and in particular to a key assembly and a watch. Background Art

[0002] A spring lug refers to a steel rod that connects the strap to the body of the watch. The strap is usually connected to the dial through a spring lug, and the unlocking and locking are ensured by the mutual movement of the lug rod. Watch manufacturers have developed a spring lug structure that uses a button to unlock. This type of spring lug structure is generally installed on the watch, and includes a housing, a button elastically connected to the housing longitudinally, and a telescopic rod elastically connected to the housing transversely. One end of the telescopic rod is inserted into the strap, and the other end is linked to the button. By pressing the button downward, the telescopic rod can be retracted into the housing to release the connection between the telescopic rod and the strap. Since the button needs to be exposed, it is usually made of metal to ensure structural strength. However, the metal material structure is relatively hard, and there is no buffer during the long-term contact with the locking rod, which is prone to severe wear and tear, affecting the service life.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0035] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0037] like Figure 1 , Figure 3 , Figure 5 as well as Figure 8 As shown, according to the embodiment of the present application, the key assembly includes a shell 10, on which a movable key 20 and a movable locking rod 30 are provided, and a mounting hole 103 is provided on the shell 10, through which the locking rod 30 is passed, and the key 20 can push the locking rod 30 to move along the mounting hole 103, and the locking rod 30 includes a first pressing portion 31, and the key 20 includes a keycap 22 and a base portion 23 that are interconnected, the structural strength of the keycap 22 is greater than the structural strength of the base portion 23, and the base portion 23 includes a second pressing portion 21, and the first pressing portion 31 and the second pressing portion 21 cooperate with each other.

[0038] According to the key assembly of the embodiment of the present application, the key 20 pushes the first pressing portion 31 through the second pressing portion 21 so that the locking rod 30 can move along the mounting hole 103. During this process, friction is generated between the first pressing portion 31 and the second pressing portion 21. The key is provided to include a keycap 22 and a base portion 23 that are connected to each other. The structural strength of the keycap 22 is greater than the structural strength of the base portion 23. In this way, while the strength of the exposed structure (keycap) of the key 22 is met, the strength of the base portion 23 is reduced, thereby reducing the structural strength of the second pressing portion 21, so that the second pressing portion 21 and the first pressing portion 31 can play a certain degree of buffering effect when they are linked to each other, avoiding excessively hard contact, thereby improving the smoothness and service life of the first pressing portion 31 and the second pressing portion 21 during the pushing process.

[0039] In some embodiments, the locking rod 30 is made of metal, the keycap 22 is made of metal, and the base 23 is made of plastic. In this way, the keycap 22 can meet the structural strength requirements of the exposed structure, and the base 23 can also absorb part of the friction between the locking rod 30 to achieve a smooth effect.

[0040] like Figure 5 and Figure 8 As shown, according to the key assembly of the embodiment of the present application, the keycap 22 defines a receiving groove, the base portion 23 includes a first sub-portion 231, the first sub-portion 231 is embedded in the receiving groove, and the structural strength of the keycap 22 is greater than the structural strength of the base portion 23.

[0041] In detail, the first sub-portion 231 is embedded in the accommodating groove, which can increase the connection reliability between the keycap 22 and the base portion 23. Since the keycap 22 is exposed to the outside, a higher structural strength is usually required to meet the strength requirements of long-term use, and the base portion 23 needs to have a pushing friction with the first pressing portion 31. The lower structural strength is set to absorb part of the friction and achieve a smooth effect.

[0042] like Figure 6 and Figure 8 As shown, in some embodiments, the keycap 22 includes a mating arm 222, the base portion 23 includes a second sub-portion connected to the first sub-portion 231, the second sub-portion is provided with a snap-in groove 232, and the mating arm 222 is snap-fitted into the snap-in groove 232. In this way, the snap-fit ​​between the mating arm 222 and the snap-in groove 232 is utilized to increase the connection reliability between the keycap 22 and the base portion 23, and at the same time, the contact area between the keycap 22 and the base portion 23 is increased, thereby further increasing the connection reliability between the keycap 22 and the base portion 23.

[0043] The sizes of the matching arm 222 and the clamping groove 232 can be set as needed, and the two can be increased or decreased accordingly to meet the fixed matching of the key cap 22 and the base 23. Fig.10 and Fig.11 Another key 20 structure is shown. Figure 6 and Figure 8 The sizes of the engagement arm 222 and the engaging groove 232 in the embodiment shown in FIG. 2 are different. In the height direction of the key cap 22 , the engagement arm 222 and the engaging groove 232 are simultaneously reduced.

[0044] like Figure 6 and Figure 7 As shown, in some embodiments, a boss 233 is provided on the second sub-part, and an anti-slip portion 223 is provided on the mating arm 222, and the anti-slip portion 223 abuts against the side of the boss 233 away from the keycap 22. In this way, the position of the keycap 22 is limited by the cooperation of the anti-slip portion 223 and the boss 233 to prevent the keycap 22 from being detached from the base portion 23.

[0045] like Figure 6 and Figure 7 As shown, in some embodiments, at least one matching column 2311 is provided on the first sub-portion 231, and at least one limiting hole 224 is provided on the keycap 22. The matching column 2311 and the limiting hole 224 correspond to each other, and the matching column 2311 is embedded in the limiting hole 224. It can be understood that the matching of the matching column 2311 and the limiting hole 224 is also used to limit the keycap 22 and the base portion 23, thereby improving the connection reliability between the keycap 22 and the base portion 23.

[0046] like Figure 6 and Figure 7 As shown, in a specific embodiment, a limiting hole 224 is provided on the keycap 22. In a specific embodiment, a plurality of limiting holes 224 are provided on the keycap 22, for example, two, three, four, five, etc., are spaced apart along the length direction of the keycap 22.

[0047] In some embodiments, the base portion 23 is fixed in the mold by injection molding, and the keycap 22 and the mold are used together to injection mold the base portion 23, thereby increasing the reliability of the connection between the key 20 and the base portion 23, reducing the gap between the two to avoid shaking, and improving the stability of the overall structure of the key 20.

[0048] like Figure 1-Figure 3 as well as Fig. 9 As shown, the height of the first pressing portion 31 gradually decreases in the direction approaching the mounting hole 103, and the first pressing portion 31 is provided with a first guide bevel 311 and a first avoidance groove 312 which are arranged in parallel along the radial direction of the locking rod 30. The button 20 includes a second pressing portion 21, and the second pressing portion 21 includes a second guide bevel 211. The first guide bevel 311 and the second guide bevel 211 are in contact with each other.

[0049] According to the key assembly of the embodiment of the present application, the key 20 pushes the first pressing portion 31 through the second pressing portion 21 so that the locking rod 30 can move along the mounting hole 103. During this process, the first guide bevel 311 and the second guide bevel 211 fit together and friction is generated therebetween. The first avoidance groove 312 can be provided to avoid the second pressing portion 21 while ensuring that the second pressing portion 21 and the first guide bevel 311 are fitted together, thereby reducing the contact area between the second pressing portion 21 and the first pressing portion 31 and reducing the friction. At the same time, the first avoidance groove 312 is convenient for giving way when the tool is grinding and polishing the first guide bevel 311 during the production process, which is beneficial to improving the smoothness of the first guide bevel 311.

[0050] In some embodiments, the width of the first avoidance groove 312 along the axial direction of the locking rod 30 can remain unchanged or vary. In order to simplify the structural setting, the width of the first avoidance groove 312 along the axial direction of the locking rod 30 is set to remain unchanged.

[0051] like Figure 2 , Figure 3 as well as Fig. 9 As shown, according to the key assembly of the embodiment of the present application, the locking rod 30 also includes a rod body portion 32, the rod body portion 32 is inserted into the mounting hole 103, the first pressing portion 31 and the rod body portion 32 are sequentially arranged along the radial direction of the locking rod 30 and are interconnected, and a second avoidance recess 321 is provided on the rod body portion 32.

[0052] Specifically, since the height of the first pressing portion 31 gradually decreases in the direction gradually approaching the mounting hole 103, in order to increase the overall structural strength of the locking rod 30, the first pressing portion 31 and the rod body portion 32 are sequentially arranged and connected to each other along the radial direction of the locking rod 30, thereby increasing the structural strength of the locking rod 30 in the radial direction and ensuring that the locking rod 30 is not easily broken during long-term use. Among them, the rod body portion 32 is provided with a second avoidance groove 321, which can further facilitate the tool to make way for the first guide bevel 311 during the production process, thereby facilitating the smoothness of the first guide bevel 311.

[0053] like Figure 3 As shown, in some embodiments, the first guide bevel 311, the first avoidance groove 312 and the second avoidance groove 321 are arranged in sequence along the radial direction of the locking rod 30, so that the first avoidance groove 312 is used to space the first guide bevel 311 and the rod body 32, so that when the second guide portion slides along the first guide portion, it is not easy to interfere with the rod body 32, thereby ensuring the normal operation of the coordination between the guarantee mechanisms.

[0054] like Figure 3 As shown, in some embodiments, the side wall 3211 of the second avoidance groove 321 away from the mounting hole 103 gradually decreases in height in the direction approaching the mounting hole 103. In this way, more space can be provided to make way for the tool to grind and polish the first guide bevel 311 during the production process, while ensuring the overall structural strength of the rod body 32.

[0055] like Figure 4 and Figure 5As shown, in some embodiments, a first reset member 40 and a second reset member 50 are provided in the housing 10, the first reset member 40 connects the lock rod 30 and the housing 10, and the second reset member 50 connects the button 20 and the housing 10. In this way, after the button 20 is released, the second reset member 50 will reset the button 20 and stop pressing the lock rod 30, and after the lock rod 30 loses the force of the button 20, it moves toward the direction close to the button 20 under the reset force of the first reset member 40, so that at least part of the lock rod 30 extending out of the housing 10 is retracted into the housing 10 to achieve reset. In this way, the dial and the strap can be adjusted by adjusting the position of the lock rod 30.

[0056] like Figure 1 As shown, in some embodiments, the housing 10 includes a first cover 101 and a second cover 102 that are buckled with each other, the second cover 102 is provided with a mounting hole 103, a locking rod 30 and a first reset member 40, the second cover 102 is provided with a button 20, and a second reset member 50 is connected between the button 20 and the first cover 101. The first reset member 40 and the second reset member 50 can both be set as springs.

[0057] like Figure 4 As shown, in some embodiments, a guide groove 1021 is provided on the second cover body 102, and the locking rod 30 is movably clamped in the guide groove 1021. The guide groove 1021 also guides the locking rod 30 to prevent the locking rod 30 from deviating during movement.

[0058] like Figure 2 As shown, in some embodiments, the locking rods 30 include two, the two locking rods 30 are symmetrically arranged, and the button 20 includes two second pressing portions 21, and the second pressing portions 21 are arranged in a one-to-one correspondence with the locking rods 30.

[0059] The watch according to the embodiment of the present application includes the above-mentioned button assembly.

[0060] The watch according to the embodiment of the present application can improve the smoothness of pressing the button 20, thereby improving the user experience.
