Description

電子裝置及其按鍵總成 Electronic device and its key assembly

本發明是有關於一種電子裝置及其按鍵總成，特別是指一種鍵帽透過傳動結構帶動多向鍵運動的電子裝置及其按鍵總成。 The invention relates to an electronic device and its key assembly, in particular to an electronic device and its key assembly in which a key cap drives a multi-directional key movement through a transmission structure.

現有例如行動電話的電子裝置通常設置有一五向鍵總成，以作為供使用者按壓的輸入介面。該五向鍵總成包括一五向鍵及一鍵帽，該五向鍵焊接於一電路板上，該鍵帽套設於該五向鍵且穿設於一殼件的一開孔，該鍵帽外周圍與該殼件相間隔一間隙。 Existing electronic devices such as mobile phones are usually provided with a five-way key assembly as an input interface for the user to press. The five-way key assembly includes a five-way key and a key cap. The five-way key is welded to a circuit board. The key cap is sleeved on the five-way key and penetrates through an opening of a shell. There is a gap between the outer periphery of the key cap and the shell.

在製造該五向鍵總成及與其配合的相關結構時，公差會發生於以下各處：1.該五向鍵內部構件之間的組裝公差；2.該五向鍵與該電路板焊接的組裝公差；3.該鍵帽與該五向鍵之間的組裝公差；4.該殼件的加工製造公差；5.該鍵帽的加工製造公差；6.該鍵帽與該殼件之間的組裝公差。 In the manufacture of the five-way key assembly and its associated structure, tolerances will occur in the following places: 1. The assembly tolerance between the internal components of the five-way key; 2. The welding of the five-way key and the circuit board Assembly tolerance; 3. Assembly tolerance between the key cap and the five-way key; 4. Manufacturing tolerance of the shell part; 5. Processing and manufacturing tolerance of the key cap; 6. Between the key cap and the shell part Assembly tolerances.

上述公差累積後極易造成該鍵帽位置偏移，使得該鍵帽與該殼件之間的該間隙不均勻，甚至是該鍵帽與該殼件產生干涉的狀況。該間隙不均勻易造成該鍵帽被按壓朝某一方向搖動的搖動行程不足，從而導致該五向鍵無法產生對應的電子訊號，並且會影響外型的美觀。該鍵帽與該殼件產生干涉會造成該鍵帽無法朝某一方向搖動，從而導致該五向鍵無法產生對應的電子訊號。 Accumulation of the above tolerances can easily cause the position of the keycap to deviate, making the gap between the keycap and the shell member uneven, or even interference between the keycap and the shell member. The uneven gap easily causes the keycap to be pressed and shaken in a certain direction with insufficient shaking stroke, which causes the five-way key to fail to generate corresponding electronic signals, and affects the appearance of the keycap. The interference between the keycap and the shell member will cause the keycap to be unable to swing in a certain direction, and thus the five-way key cannot generate a corresponding electronic signal.

Circuit board 1. Thereby, it can be ensured that the cap 34, the opening 25 and the transmission disc 32 are assembled The relative position after installation is correct, so that the cap 34 can be maintained in a position where it passes through the opening 25 and is stacked on the drive disc 31.

參閱圖7，當使用者施加一按壓力F按壓該端壁340的其中一個對應的該角隅部344時，該角隅部344會將該按壓力F經由該圍繞壁體346傳遞至對應的該接觸凸塊347，而該接觸凸塊347會透過該第二圓弧面349將該按壓力F傳遞至該盤體322的該盤面324，使得該傳動盤32能透過該套筒321帶動該搖桿311沿一搖動方向R搖動，以使該多向鍵31產生一對應的電子訊號。藉由該接觸凸塊347的該第二圓弧面349以點接觸方式接觸該盤面324，使得該接觸凸塊347能將該圍繞壁體346所傳遞的該按壓力F集中並施加於該盤面324，藉此，能提升該按壓力F傳遞至該盤面324的力道及施力位置準確性，使得該傳動盤32能迅速地帶動該搖桿311沿該搖動方向R搖動並使該多向鍵31產生對應的該電子訊號。 Referring to FIG. 7, when the user applies a pressing force F to press one of the corresponding corner portions 344 of the end wall 340, the corner portion 344 will transmit the pressing force F to the corresponding corner portion 344 through the surrounding wall 346 The contact protrusion 347, and the contact protrusion 347 transmits the pressing force F to the disk surface 324 of the disk body 322 through the second arc surface 349, so that the transmission disk 32 can drive the drive disk 32 through the sleeve 321 The rocker 311 is rocked along a rocking direction R so that the multi-directional key 31 generates a corresponding electronic signal. The second arc surface 349 of the contact bump 347 contacts the disk surface 324 in a point contact manner, so that the contact bump 347 can concentrate the pressing force F transmitted by the surrounding wall 346 and apply it to the disk surface 324. By this, the accuracy of the force and position of the pressing force F transmitted to the disk surface 324 can be improved, so that the transmission disk 32 can quickly drive the rocker 311 to rock in the rocking direction R and make the multi-directional key 31 generates the corresponding electronic signal.

參閱圖8，當使用者施加該按壓力F按壓該端壁340的該接觸壁體343時，該接觸壁體343會透過該第一圓弧面345將該按壓力F傳遞至該套筒321的該端面323，使得該傳動盤32能透過該套筒321帶動該搖桿311沿一平行於該按壓力F的移動方向D移動，以使該多向鍵31產生一對應的電子訊號。藉由該接觸壁體343的該第一圓弧面345以點接觸方式接觸該端面323，使得該接觸壁體343能將該按壓力F集中並施加於該端面323，藉此，能提升該按壓力傳遞至該端面323的力道及施力位置準確性，使得該傳動盤32能迅速地帶動該搖桿311沿該移動方向D移動並使該多向鍵31產生對應的該電子訊號。 Referring to FIG. 8, when the user applies the pressing force F to press the contact wall 343 of the end wall 340, the contact wall 343 will transmit the pressing force F to the sleeve 321 through the first arc surface 345 The end surface 323 enables the drive plate 32 to drive the rocker 311 through the sleeve 321 to move in a moving direction D parallel to the pressing force F, so that the multi-directional key 31 generates a corresponding electronic signal. The first arc surface 345 of the contact wall 343 contacts the end surface 323 in a point contact manner, so that the contact wall 343 can concentrate and apply the pressing force F to the end surface 323, thereby lifting the Press pressure The force transmitted to the end surface 323 and the accuracy of the applied force position enable the drive plate 32 to quickly drive the rocker 311 to move in the moving direction D and cause the multi-directional key 31 to generate the corresponding electronic signal.

參閱圖2及圖4，藉由該按鍵總成3的該傳動盤32組裝於該多向鍵31的該搖桿311，以及該鍵帽33組裝於該殼件2並且堆疊於該傳動盤32的設計方式，使得該鍵帽33組裝在該殼件2後的位置不會受到該多向鍵31內部構件之間的組裝公差，以及該多向鍵31與該電路板1焊接的組裝公差所影響，並且還能克服先前技術所述的該鍵帽與該五向鍵之間的組裝公差影響。藉此，能避免前述公差累積造成該鍵帽33的該帽蓋34位置偏移，使得該帽蓋34與該殼件2的該內周面23之間的該間隙G能保持均勻以維持外型的美觀，還能防止該帽蓋34與該殼件2產生干涉，以確保該帽蓋34***作時能夠透過該傳動盤32帶動該搖桿311運動而使該多向鍵31產生對應的該電子訊號。 2 and 4, the drive plate 32 of the key assembly 3 is assembled to the rocker 311 of the multi-directional key 31, and the key cap 33 is assembled to the housing 2 and stacked on the drive plate 32 The design method makes the position of the keycap 33 assembled on the housing 2 not be affected by the assembly tolerance between the internal components of the multi-directional key 31 and the assembly tolerance of the welding of the multi-directional key 31 and the circuit board 1. It can also overcome the influence of the assembly tolerance between the keycap and the five-way key described in the prior art.
