—起固設於本體22上。 可以理解’第一磁性件222之形狀不限於方形’其還 •可為圓形、稜形、三角形等其他形狀，第一套殼224上之 通孔2240之大小及形狀與之對應。第一磁性件222可與第 一套殼224 —體成型，第一套殼224還可直接成型於本體 22上。 第二磁性件226、228分別設置於本體22第一磁性件 222之兩側，並分別與第一磁性件222有一定之間距。 第一定位栓230設於本體22 —端之兩側’其一端可供 滑桿26插入。第二定位栓232設於本體22另一端之兩側， 其靠近第一定位栓230之一端也可供滑桿26插入。 蓋體24為與本體22大小基本相同之長方形板體，其 包括一第三磁性件242、一第三套殼244、二第四磁性件 246、248及設於蓋體24兩侧之滑動部250。 第三磁性件242為方形磁性件’其大小及形狀對應於 ❿本體22之第一磁性件222,其設置於蓋體24之中心位置。 請一併參見圖4，第三套殼244為四側板圍成之方形框體， 該四側板依次連接從而圍成一方形通孔2440 ’該通孔2440 之大小及形狀對應於第三磁性件242。第三套殼244上二 相對之側板2442之同一側表面上各形成有一凸部2444 ’ 該凸部2444用於與本體22第一套殼224之凹部2244配 合。組裝時，先將第三磁性件242固定於第三套殼244之 通孔2440内，然後將第三磁性件242及第二套殼244 —起 200928138 鑲嵌於蓋體24上開設之通孔内，這樣二者可沿該通孔之軸 線即垂直於蓋體24之方向上移動。 • 可以理解，第三磁性件242之形狀不限於方形，其還 可為圓形、稜形、三角形等其他形狀，第三套殼244上之 通孔2440之大小及形狀與之對應。第三磁性件242可與第 三套殼244 —體成型。 第四磁性件246、248分別設置於蓋體24第三磁性件 242之兩側，其中，第四磁性件246、248之設置位置分別 對應於本體22之第二磁性件226、228之設置位置。本體 22之第一磁性件222與蓋體24之第三磁性件242磁性之 強弱相同，本體22之第二磁性件226、228與蓋體24之第 四磁性件246、248磁性之強弱相同，且第一磁性件222 與第三磁性件242之磁性強於第二磁性件226、228與第四 磁性件246、248之磁性。 二滑動部250分別設於蓋體24之兩側，其上設有半圓 ©形凹槽252，該凹槽252用於與滑桿26套合。 滑桿26為圓柱形桿體，其兩端分別插設於第一定位栓 230及第二定位栓232之端部。 組裝時，先將二滑桿26插入本體22之第一定位栓230 及第二定位栓232之端部，然後將蓋體24之二滑動部250 分別套於二滑桿26上，蓋體24可沿滑桿26相對於本體 22滑動。本體22之第一磁性件222與蓋體24之第三磁性 件242相互靠近側之磁極性相反，在本實施例中，第一磁 200928138 性件222靠近蓋體24侧之磁極性為S極，第三磁性極242 •靠近本體22側之磁極性為N極，所以第一磁性件222與 •第三磁性件242可相互吸引。本體22之第二磁性件226、 228之位置分別對應於蓋體24之第四磁性件246、248之 位置，且第二磁性件226、228與第四磁性件246、248相 互靠近側之磁極性相同。在本實施例中，本體之第二磁性 件226、228靠近蓋體24侧之磁極性分別為S極、N極， 蓋體之第四磁性件246、248靠近本體22側之磁極性分別 ® 為S極、N極。因此，本體22之第二磁性件226、228與 蓋體24之第四磁性件246、248相互排斥。 請參見圖1及圖5,蓋體24完全蓋合於本體22上時， 本體22之第一磁性件222與蓋體24之第三磁性件242相 互吸引，且本體22之第一套殼224之凹部2244與蓋體24 之第三套殼244之凸部2444相配合。 請一併參見圖6,需要將蓋體24滑開時，朝靠近本體 ❿22之第一定位栓230之方向推動蓋體24，將蓋體24之第 三套殼244之凸部2444漸漸推出本體22之第一套殼224 之凹部2244之過程中，第三套殼244之凸部2444在垂直 於蓋體24之方向上作輕微之移動，從而使得凸部2444完 全脫離凹部2244。隨後，蓋體24之第三磁性件242開始 遠離本體22之第一磁性件222。蓋體24與本體22上磁極 性相反之磁性件之間產生磁吸引力，如本體22之第一磁性 件222與蓋體24之第三磁性件242間產生磁吸引力，磁極 性相同之磁性件之間產生磁排斥力，如本體22之第二磁性 11 200928138 件226、228與蓋體24之第四磁性件246、248間產生磁排 ’斥力。隨著蓋體24之滑動，當蓋體24與本體22間之磁排 '斥力之和大於磁吸引力之和時，在磁排斥力之推動下，蓋 體24相對於本體22自動滑開，直至蓋體24之滑動部250 與本體22之第一定位栓230相抵。. 需要將蓋體24完全蓋合於本體22上時，朝靠近本體 22第二定位栓232之方向推動蓋體24，當蓋體24之磁性 件與本體22之磁性件間之磁吸引力之和大於磁排斥力之 和時，在磁吸引力之推動下，蓋體24將自動滑動，蓋體 24之第三套殼244之凸部2444在垂直於蓋體24且靠近本 體22之第一套殼224之凹部2244之方向上移動，並慢慢 滑入凹部2244内，二者相互配合。蓋體24之滑動部250 與本體22之第二定位栓232相抵，蓋體24完全蓋合於本 體22上。此時，蓋體24之第四磁性件246、248之位置分 別對應於本體22之第二磁性件226、228,第四磁性件246、 ❿248與第二磁性件226、228之間會產生磁排斥力。因為蓋 體24之第三套殼244之凸部2444與本體22之第一套殼 224之凹部2244緊密之配合在一起，所以蓋體24與本體 22上極性相同之磁性件產生排斥力不會造成蓋體24相對 於本體22晃動，從而增強了蓋體24與本體22間滑動連接 之平穩性。 可以理解，第一套殼224可設有凸部，相對應地，第 三套殼244上設有凹部。可將第三磁性件242與第三套殼 244 —起固定於蓋體24上，而將第一磁性件222與第一套 12 200928138 殼224 —起鑲嵌於本體22之通孔内，使其可沿該通孔之軸 線即垂直於本體22之方向上移動。 ’ 在本實施例中，蓋體24相對於本體22具有兩種位置， 第一位置為蓋體24相對於本體22完全閉合，此時蓋體24 之第三套殼244之凸部2444與本體2.2之第一套殼224之 凹部2244相互配合；第二位置為蓋體24相對於本體22 滑開，此時蓋體24之滑動部250與本體22之第一定位栓 230相抵。 可以理解，蓋體24之滑動部250之長度及位置直接影 響到蓋體24相對於本體22之滑動行程及位置關係，比如 將蓋體24之滑動部250長度縮短，蓋體24相對於本體22 之滑動行程會增大。另外，改變蓋體24滑動部250之位置 或長度可使蓋體24相對於本體22具有三種位置，第一位 置為蓋體24相對於本體22完全閉合，此時蓋體24之第 三套殼244之凸部2444與本體22之第一套殼224之凹部 © 2244相互配合；第二位置為蓋體24相對於本體22滑開， 蓋體24之滑動部250與本體22之第一定位栓230相抵； 第三位置為蓋體24相對於本體22滑開，蓋體24之滑動部 250與本體22之第二定位栓232相抵。也可以通過調整本 體22第一定位栓230及第二定位栓232之位置及長度來調 整蓋體24相對於本體22之滑動行程及位置。 可以理解，本發明滑動裝置20之本體22與蓋體24 中磁性件之數量及磁極性設置不限於本實施例中之描述， 本體22上可設置至少一第一磁性件222，本體22上可設 13 200928138

本體42之第一磁性件422與蓋體44之第二磁性件442相 ❹靠近側之磁極性相反。 蓋體44完全蓋合於本體42上時，蓋體44之第二磁性 件442與本體22 —端之第一磁性件422之位置相對應並相 互吸引，第二套殼444之凸部4442與第一套殼426之凹部 4262相配合，從而使蓋體44不可相對於本體22晃動。推 開蓋體44,請參見圖8,蓋體44之第二磁性件442與第二 套殼444沿蓋體44之垂線朝遠離本體42之第一套殼426 凹部4262之方向移動，第二套殼444之凸部漸漸滑出第一 套殼426之凹部4262。繼續滑動蓋體44，當蓋體44之第 14 200928138 二磁性件442與本體42—端之第一磁性件422之吸引力小 於與其另一端之第一磁性件422之吸引力時，蓋體44自動 -滑開，請參見圖9，直至蓋體44之第二磁性件442與本體 42之第一磁性件422相互吸引，第二套殼444與第一套殼 426相互配合。將蓋體44滑動閉合於本體42時之作用原 理與此相同。 可以理解，本體42上也可只設置一第一套殼426，第 一套殼426上可設有凸部，相應地，蓋體44之第二套殼 〇 444上設有凹部，第一套殼426可沿垂直於本體42或蓋體 44之方向移動。 請參見圖10，本發明較佳實施例三之滑動裝置60包

It is slidable relative to the body 22 along the slide bar 26. The magnetic polarity of the first magnetic member 222 of the main body 22 and the third magnetic member 242 of the cover body 24 are opposite to each other. In the embodiment, the magnetic polarity of the first magnetic 200928138 member 222 near the side of the cover 24 is S pole. The third magnetic pole 242 • the magnetic polarity near the body 22 side is N pole, so the first magnetic member 222 and the third magnetic member 242 can attract each other. The positions of the second magnetic members 226, 228 of the body 22 respectively correspond to the positions of the fourth magnetic members 246, 248 of the cover body 24, and the magnetic poles of the second magnetic members 226, 228 and the fourth magnetic members 246, 248 are close to each other. The same sex. In this embodiment, the magnetic polarities of the second magnetic members 226 and 228 of the body near the cover 24 are S and N, respectively, and the magnetic polarities of the fourth magnetic members 246 and 248 of the cover near the body 22 are respectively. It is S pole and N pole. Therefore, the second magnetic members 226, 228 of the body 22 and the fourth magnetic members 246, 248 of the cover 24 repel each other. Referring to FIG. 1 and FIG. 5, when the cover body 24 is completely covered on the main body 22, the first magnetic member 222 of the main body 22 and the third magnetic member 242 of the cover body 24 are attracted to each other, and the first sleeve 224 of the main body 22 is 224. The recess 2244 mates with the projection 2444 of the third sleeve 244 of the cover 24. Referring to FIG. 6 together, when the cover body 24 needs to be slid open, the cover body 24 is pushed toward the first positioning pin 230 of the main body ❿ 22, and the convex portion 2444 of the third sleeve 244 of the cover body 24 is gradually pushed out of the body. During the recess 2244 of the first set of shells 224 of 22, the projections 2444 of the third set of shells 244 are slightly displaced in a direction perpendicular to the cover 24 such that the projections 2444 are completely disengaged from the recesses 2244. Subsequently, the third magnetic member 242 of the cover 24 begins to move away from the first magnetic member 222 of the body 22. The magnetic attractive force is generated between the cover body 24 and the magnetic member having the opposite magnetic polarity on the body 22, such as the magnetic attraction between the first magnetic member 222 of the body 22 and the third magnetic member 242 of the cover body 24, and the magnetic polarity is the same. A magnetic repulsive force is generated between the pieces, such as a magnetic repulsion between the second magnetic 11 200928138 pieces 226, 228 of the body 22 and the fourth magnetic pieces 246, 248 of the cover 24. As the cover 24 slides, when the sum of the repulsive forces between the cover 24 and the body 22 is greater than the sum of the magnetic attractive forces, the cover 24 automatically slides away relative to the body 22 under the push of the magnetic repulsive force. Until the sliding portion 250 of the cover 24 abuts the first positioning pin 230 of the body 22. When the cover body 24 needs to be completely covered on the body 22, the cover body 24 is pushed toward the second positioning pin 232 of the body 22, and the magnetic attraction between the magnetic member of the cover body 24 and the magnetic member of the body 22 is When the sum is larger than the magnetic repulsive force, the cover body 24 will automatically slide under the push of the magnetic attraction force, and the convex portion 2444 of the third sleeve 244 of the cover body 24 is perpendicular to the cover body 24 and close to the first body 22 The recess 2244 of the casing 224 moves in the direction of the recess and slowly slides into the recess 2244, which cooperate with each other. The sliding portion 250 of the cover body 24 abuts against the second positioning pin 232 of the body 22, and the cover body 24 is completely covered on the body 22. At this time, the positions of the fourth magnetic members 246, 248 of the cover body 24 respectively correspond to the second magnetic members 226, 228 of the body 22, and magnetic waves are generated between the fourth magnetic members 246, 248 and the second magnetic members 226, 228. Repulsive force. Because the convex portion 2444 of the third casing 244 of the cover body 24 is closely fitted with the concave portion 2244 of the first casing 224 of the body 22, the magnetic force of the same polarity on the cover body 24 and the body 22 does not cause repulsive force.

It can be understood that the length and position of the sliding portion 250 of the cover body 24 directly affect the sliding stroke and positional relationship of the cover body 24 relative to the body 22, such as shortening the length of the sliding portion 250 of the cover body 24, and the cover body 24 is opposite to the body 22. The sliding stroke will increase. In addition, changing the position or length of the sliding portion 250 of the cover body 24 allows the cover body 24 to have three positions relative to the body 22, the first position being that the cover body 24 is completely closed with respect to the body 22, and the third casing of the cover body 24 at this time. The convex portion 2444 of the 244 and the recess portion 2244 of the first sleeve 224 of the body 22 cooperate with each other; the second position is that the cover body 24 slides relative to the body 22, and the sliding portion 250 of the cover body 24 and the first positioning bolt of the body 22 The third position is that the cover body 24 slides relative to the body 22, and the sliding portion 250 of the cover body 24 abuts against the second positioning pin 232 of the body 22.
