Description

可收折帐篷
本申请要求2022年3月28日提交的申请号为CN 2022103293437的中国专利申请的优先权。
技术领域
本公开属于户外用品领域，涉及一种可收折帐篷，具体是一种具有挑檐杆的可收折帐篷。
背景技术
帐篷广泛应用于户外活动，例如户外宿营等，其既能防风、防雨、防蚊虫，又有保暖功效。已有的一种可收折帐篷遮阳面积较小，为了增大帐篷张开后的遮阳面积，出现了带挑檐结构的挑檐式帐篷，在帐篷的顶角处设有伸出的挑檐杆，通过设在挑檐杆上的围布达到增大遮阳面积的目的。这种帐篷主要通过在构成蓬顶支架的顶杆上枢接挑檐杆或插接挑檐杆，在帐篷主体展开后，可以选择性地将挑檐丝杆伸出，以增大遮阳面积。然而，现有的这种帐篷可能存在挑檐杆伸出后强度不够的问题。

具体实施方式
下面结合附图对本公开的较佳实施例进行详细阐述，以使本公开的优点和特征能更易于被本领域的技术人员理解。在此需要说明的是，对于这些实施方式的说明用于帮助理解本公开，但并不构成对本公开的限定。此外，下面所描述的本公开各个实施方式中所涉及到的技术特征只要彼此之间未构成冲突就可以互相结合。
图1至图12示出了可收折帐篷的一个示例。参照图1至图12所示，该可收折帐篷具有展开状态和收折状态，其包括可收折的帐篷架主体2；帐篷架主体2能够独立地支撑于地面上，帐篷架主体2上覆有布套(图中未示出)，用以遮阳、挡风避雨等；其中布套的一部分(例如边缘部分)能够垂于帐篷架主体2的旁侧，这部分布套称之为围布。结合图1及图3至图5所示，该帐篷架主体2包括多个沿上下方向延伸的腿杆1及连接于腿杆1上部的顶架，通过腿杆1支撑在地面上，布套主要覆于顶架上。该帐篷还包括具有内端部和外端部的挑檐杆3，挑檐杆3的内端部可转动地连接于腿杆1，具体通过枢轴连接。挑檐杆3为多个，且数量及位置与腿杆1一一对应，即，各挑檐杆3的内端部可转动地连接于对应的腿杆1，上述的围布连接于挑檐杆3的外端部，而能够被挑檐杆3撑开以作为屋檐来增大遮阳面积，还能够随挑檐杆3的折叠而垂在帐篷的旁侧，用作侧围布。每个挑檐杆3分别具有折叠状态和打开状态，挑檐杆3的外端部在折叠状态时和腿杆1相靠拢而在打开状态时偏离腿杆1一段距离。也就是说，挑檐杆3具有和腿杆1相靠拢的折叠状态、以及相对腿杆1展开的打开状态。挑檐杆3展开后，使围布向外伸展，能够增大帐篷的遮阳面积。进一步地，左侧的挑檐杆3在其打开状态时向左延伸，也就是说挑檐杆3的外端部位于腿杆1 的左侧；右侧的挑檐杆3在其打开状态时向右延伸，也就是说挑檐杆3的外端部位于腿杆1的右侧；从而能够将左侧和右侧的围布撑开，增大帐篷左侧和右侧的屋檐面积，增大左右两侧的遮阳面积。挑檐杆3在折叠状态时，围布下垂，位于帐篷的侧边。
顶架包括多个可折叠的屋檐架21，屋檐架21连接于相邻的腿杆1之间。该帐篷还包括多个横杆4，多个横杆4的数量和位置与多个挑檐杆3一一对应。结合图7至图12所示，各横杆4具有可转动地连接于挑檐杆3的第一端部及用于与屋檐架21可拆卸连接的第二端部。挑檐杆3在折叠状态时横杆4的第二端部和屋檐架21脱离，挑檐杆3在打开状态时横杆4的第二端部和屋檐架21连接。帐篷架主体2由展开状态切换为收折状态的过程中，横杆4的第二端部和屋檐架21脱离，挑檐杆3由打开状态转换为折叠状态。横杆4的第二端部和屋檐架21的杆件采用可拆卸地连接方式，并配置为在屋檐架21折叠时受到来自挑檐杆3的力而能够自动脱离屋檐架21，下文将详细描述其中的一种实现方式。
还需要说明的是：本实施例中，挑檐杆3通过枢轴直接转动连接于腿杆1上；在其他一些实施例中，挑檐杆3可通过其他部件间接地转动连接于腿杆1上，例如通过腿杆1上的滑套、连接帽等转动连接。
屋檐架21包括能够在帐篷架主体2折叠时向下转动的连杆211；横杆4的第二端部上形成有能够卡于连杆211上的卡槽部41，卡槽部41具有面向下方的槽口410，如图12所示。卡槽部41所形成的卡槽优选为自卡槽部41的下表面向上延伸，且卡槽部41的垂直于连杆211的长度方向的截面中，卡槽的轮廓大体为倒置的U形。帐篷架主体2在折叠时，连杆211会向下转动，从而自卡槽部41的卡槽中脱离，横杆4和屋檐架21解除连接，避免因为忘记收折挑檐杆3而导致帐篷架主体2不可折叠、或挑檐杆3及帐篷架主体2的杆件损坏。本实施例中，挑檐杆3不是沿帐篷的对角方向打开；如图3和图4所示，各挑檐杆3沿第一个屋檐架21(例如位于前侧的屋檐架)的长度方向延伸，即在俯视时，挑檐杆3与该第一个屋檐架21的延伸方向大体相同。与该挑檐杆3相接的横杆4和第二个屋檐架21可拆卸连接，该第二个屋檐架21与上述第一个屋檐架21相交，例如位于左侧的屋檐架。
结合图10b至图12所示，与横杆4配合的连杆211上形成有定位凸起211a，卡槽部41具有与定位凸起211a相配合的定位槽411，用以限制卡槽部41沿连杆211的长度方向上的滑动。上述定位槽411和卡槽部41所形成的卡槽相互连通且自卡槽部41的下表面向上延伸，在卡槽部41卡到连杆211上的过程中，定位凸起211a进入定位槽411中；定位槽411具有相对的两个限位壁，限位壁整体与连杆211的长度方向不相平行；定位凸起211a位于该两个限位壁之间，阻止卡槽部41在连杆211上前后移动。定位凸起211a具体包括固定于连杆211上的销钉、拉钉或铆钉；更进一步地，该定位凸起211a位于连杆211与其他杆件(优选为屋檐架的其他杆件)的枢接处，其可以为将连杆211和其他杆件枢接的枢轴的一部分或设置于该枢轴上。本实施例中，每个横杆4由单根杆组成；而在其他一些实施例中，横杆4可以由多个杆件组成。
该帐篷还包括具有第一端部和第二端部的支撑杆5，支撑杆5为多个，多个支撑杆5的数量和位置与多个挑檐杆3一一对应。结合图2b、图7至图12所示，各支撑杆5的第一端部可转动地且可沿上下方向滑动地连接于腿杆1，而第二端部可转动地连接于挑檐杆3。具体地，支撑杆5的第一端部可转动地连接于支撑座51，支撑座51可沿上下方向滑动地连接于腿杆1。支撑座51优选为能够沿上下方向滑动地套设于腿杆1上的滑动套，支撑杆5的下端部枢轴连接于该滑套而上端部枢轴连接于挑檐杆3。支撑座51和腿杆1之间设有挑檐锁定机构，挑檐杆3在打开状态时挑檐锁定机构将支撑座51和腿杆1锁定。该挑檐锁定机构可采用已知的结构，例如支撑座51上设有可活动的锁定件(图中未示出)，腿杆1上设有与锁 定件相配合的锁孔102，锁定件可脱离地插于该锁孔102内。在打开状态时，支撑座51上的锁定件插入锁孔102中，将挑檐杆3锁定在打开状态，使其稳定地展开；需要转换为折叠状态时，按压支撑座51上的解锁按钮52，使锁定件脱离锁孔102，支撑座51下滑至腿杆1的下部，带动挑檐杆3收折，至其外端部和腿杆1相靠拢，同时支撑杆5的第一端部(下端部)也和腿杆1的下端部相互靠拢。
进一步地，挑檐杆3的内端部和外端部之间设置有固定座30，固定座30大约位于挑檐杆3的中部位置。横杆4的第一端部通过第一枢轴301可转动地连接于固定座30，支撑杆5的第二端部(上端部)通过第二枢轴302可转动地连接于固定座30。挑檐杆3在折叠状态时第一枢轴301和/或第二枢轴302的轴心线与水平面之间构成的夹角小于10度。具体而言，挑檐杆3在折叠状态时，第一枢轴301的轴心线、第二枢轴302的轴心线优选为平行于水平面或仅倾斜一较小的角度，且挑檐杆3与腿杆1相连的枢轴的轴心线也优选为平行于水平面或仅倾斜一较小的角度，从而挑檐杆3、横杆4能够在自身重力的作用下自动下落且垂在腿杆1的旁侧。进一步地，挑檐杆3在折叠状态时，支撑杆5靠拢在挑檐杆3的前侧或后侧；而且，从前侧或后侧看，支撑杆5完全被挑檐杆3遮挡。
结合图2b、图7至图9所示，腿杆1包括沿上下方向延伸的腿杆主体10、固定于腿杆主体10的上端部的固定节11、及固定于腿杆主体10的下端部的脚垫12；挑檐杆3的内端部枢轴连接于固定节11，支撑座51滑动地套设于腿杆主体10上，锁孔102开设于腿杆主体10上。脚垫12提供较大的与地面接触的接触面积，部分腿杆1(例如右侧的两个腿杆1)的脚垫12上设有滚轮13，便于帐篷的运输。若无特殊说明，下文所述的“腿杆1的上端部”、“腿杆1的下端部”分别是指固定节11和脚垫12。进一步地，部分或全部的脚垫12上设有插孔；该帐篷在收折后，可将下端开口的防护包罩在帐篷上，防护包的下端通过连接组件固定在插孔上，例如通过将连接带上的插销插入脚垫12的插孔内，将防护包固定在帐篷上。
结合图1、图3至图5所示，本实施例的顶架包括多个可折叠的屋檐架21及多个可折叠的顶杆单元22。屋檐架21连接于相邻的腿杆1之间；腿杆1的数量为四个，则帐篷的前后左右四侧均设有一个屋檐架21。每个屋檐架21包括至少一个可转动地连接于相邻的腿杆1之间的连杆组件210，每个连杆组件210包括两个能够相对展开和靠拢的连杆211，两个连杆211的中部通过第三枢轴212相转动连接，而构成十字交叉的类似剪刀的结构。腿杆1的上端部(具体为固定节11)和与其相接的连杆组件210中的一个连杆211的一端部枢轴连接；腿杆1(具体为腿杆主体10)上还设有滑套101，该滑套101能够沿上下方向滑动地套设于腿杆1上，该滑套101和该连杆组件210中的另一个连杆211的一端部枢轴连接。在折叠时，滑套101向下滑动，连杆组件210的两个连杆211在横向上相互靠拢，使腿杆1相互靠拢，从而减小帐篷在前后左右方向上的尺寸，如图6所示。具体到本实施例中，每个屋檐架21由三个依次转动连接的连杆组件210构成。上述的卡槽部41优选为与腿杆1的上端部相连接的那个连杆211的上端部可拆卸连接，上述的定位凸起211a也形成于该连杆211的上端部。
各顶杆单元22分别包括一端部相转动连接的内顶杆222和外顶杆221，外顶杆221的另一端部可转动地连接于腿杆1的上端部，各顶杆单元22的内顶杆222的另一端部可转动地连接于一中心锁定机构23。中心锁定机构23包括能够相互锁合或脱离的顶帽231和底帽232，内顶杆222的另一端部可转动地连接于顶帽231；各顶杆单元22还分别包括辅顶杆223，辅顶杆223的一端部可转动地连接于内顶杆222而另一端部可转动地连接于底帽232。各顶杆单元22还分别包括斜杆224，斜杆224的上端部可转动地连接于外顶杆221，下端部可转动地连接于腿杆1上的滑套101。当顶帽231和底帽232锁合后，帐篷架主体2 通过中心锁定机构23锁定在展开状态；当顶帽231和底帽232解除锁合后，斜杆224随着滑套101向下移动，而拉动顶杆单元22折叠，即外顶杆221和内顶杆222向下转动，使得外顶杆221的内端部、内顶杆222的外端部向腿杆1的下端部靠拢，顶帽231和腿杆1的上端部相互靠拢，辅顶杆223的下端部及底帽232和内顶杆222的外端部相互靠拢。
帐篷架主体2还包括连接于屋檐架21和中心锁定机构23之间的加强机构6。具体地，该加强机构6包括一端部相转动连接的外加强杆621和内加强杆622，外加强杆621的另一端部可转动地连接于屋檐架，外加强杆621的另一端部可转动地连接于中心锁定机构23，具体为顶帽231。该加强机构6还包括辅加强杆623，辅加强杆623的一端部可转动地连接于内加强杆622而另一端部可转动地连接于底帽232。本实施例中，外加强杆621的另一端部可转动地连接于中间的连杆组件210的交叉连接处。具体地，外加强杆621的另一端部通过第四枢轴621a可转动地连接于一连接件624，连接件624固定连接于第三枢轴212，第四枢轴621a的轴心线和第三枢轴212的轴心线之间构成大于零且小于180度的夹角，优选为相互垂直。本实施例的帐篷具有两个加强机构6，分别设于顶架的左侧和右侧。
该帐篷的使用方法如下：将帐篷架主体2展开，展开后将顶帽231和底帽232相互锁合，使帐篷稳定展开，如图1所示，可以根据需要选择将一侧的挑檐杆3打开，如图3所示；或选择将两侧的挑檐杆3打开，如图4和5所示。挑檐杆3打开的具体过程为：将挑檐杆3抬起，支撑座51随之向上移动，将横杆4的第二端部卡到连杆211上的定位凸起211a处，挑檐锁定机构锁定使挑檐杆3稳定处于其打开状态。挑檐杆3折叠的具体过程为：使挑檐锁定机构解锁，使横杆4的第二端部脱离连杆211，在自身重力的作用下，支撑座51下滑，挑檐杆3和横杆4自动下垂至腿杆主体10的旁侧。需要将帐篷收折时，可预先将挑檐杆3收起；若忘记收起，则在帐篷架主体2折叠的过程中，在外力的挤压作用下横杆4能够自动脱离连杆211而被释放，具体为：将顶帽231和底帽232解锁，腿杆主体10上的滑套101下移，屋檐架21的连杆211相互转动靠拢，尤其是与横杆4相连的那个连杆211向下转动，从卡槽部41上的槽口410脱离，帐篷架主体2正常收折。
该帐篷在展开后，能够根据需要灵活选择打开或收合挑檐杆3，且打开和收合快速且方便；横杆4能够在挑檐杆3打开后对其进行加强，具有较好的强度；特别是，在收折帐篷时，若忘记将挑檐杆3收合，则随着屋檐架21折叠，横杆4的第二端部能够在外力作用下自动和屋檐架21的连杆211脱离，不会因为忘记收合挑檐杆3而造成挑檐杆3意外折断或帐篷架主体2的结构被破坏。此外，在屋檐架21和中心锁定机构23之间设置可折叠的加强机构6，能够随帐篷架主体2展开和收折的同时，能够抵消或减小横杆4对于屋檐架21的推力，避免因横杆4的推力导致的屋檐架21内凹变形的问题。帐篷架主体2由中心锁定机构23锁定，能够快速打开和收合。
图14至图16示出了可收折帐篷的另一个示例，其与上述的可收折帐篷的区别仅在于加强机构6不同。参照图14至图16所示，本实施例的加强机构6连接于屋檐架21和顶杆单元22之间。加强机构6包括加强杆610，加强杆610的一端部可转动地连接于内顶杆222，而另一端部可转动地连接于屋檐架21(具体为两个相邻连杆组件210的处于上方的转动连接处)。具体地，加强杆610的一端部枢轴连接于内顶杆222，且二者的连接处与内顶杆222的内端部的间距小于内顶杆222长度的三分之一；加强杆610的另一端部枢轴连接于一连接头611，上述两个相邻连杆组件210的连杆211通过该连接头611转动连接。本实施例的帐篷具有八个加强杆610，每个屋檐架21分别通过两个加强杆610转动连接于相邻的两个顶杆单 元22的内顶杆222上，将四组屋檐架21和顶杆单元22都分别连接起来形成一个加强结构，从而减小对于屋檐架21因为横杆4的推力所造成的屋檐架21内凹变形的问题。加强杆610能够对着帐篷架主体2的展开和收折而相应转动，不影响帐篷架主体2的展开和收折。
图14示出了带有围布70的帐篷。左侧的两个挑檐杆3打开，因而左侧的围布70被撑起，用于增大遮蔽面积；而右侧的两个挑檐杆3未打开，右侧的围布70垂于帐篷右侧，具体位于右侧两个腿杆1的右侧。进一步地，横杆4和屋檐架21的连接处低于围布70。
图17至图19示出了可收折帐篷的又一个示例，其与图1至图12所示的可收折帐篷的区别仅在于：挑檐杆3与帐篷架主体的连接方式不同。结合图17至图19所示，挑檐杆3可脱离地插接于腿杆1，而非和腿杆1转动连接。具体而言，挑檐杆3的内端部通过腿杆1上的滑套101而和腿杆1可脱离地插接。滑套101上设有插槽101a，插槽101a大体倾斜延伸。挑檐杆3在打开状态时，挑檐杆3的内端部插入插槽101a中而和腿杆1连接；挑檐杆3在折叠状态时，挑檐杆3的内端部自插槽101a中拔出而和腿杆1脱离。在帐篷架主体折叠时，横杆4同样能够和屋檐架21的连杆211自动脱离。
图20和图21示出了可收折帐篷的第四个示例，其与图1至图12所示的可收折帐篷的区别仅在于：挑檐杆3与帐篷架主体的连接方式不同。结合图20和图21所示，挑檐杆3可脱离地插接于腿杆1，而非和腿杆1转动连接。具体而言，挑檐杆3的内端部和腿杆1的固定节11可脱离地插接。固定节11上设有插槽11a，插槽11a大体倾斜延伸。挑檐杆3在打开状态时，挑檐杆3的内端部插入插槽11a中而和腿杆1连接；挑檐杆3在折叠状态时，挑檐杆3的内端部自插槽11a中拔出而和腿杆1脱离。在帐篷架主体折叠时，横杆4同样能够和屋檐架21的连杆211自动脱离。
图22至图24示出了可收折帐篷的第五个示例，其与图1至图12所示的可收折帐篷的区别仅在于：挑檐杆3、横杆4及支撑杆5三者的连接方式不同。具体而言，结合图22至图24所示，挑檐杆3上的固定座30与一旋转座31相转动连接，横杆4的第一端部和旋转座31通过枢轴a1可转动地连接，支撑杆5的第二端部和固定座30通过枢轴a2可转动地连接。进一步地，通过枢轴a2将旋转座31、固定座30及支撑杆5的第二端部三者转动连接。
图25至图27示出了可收折帐篷的第六个示例，其与图1至图12所示的可收折帐篷的区别仅在于：挑檐杆3、横杆4及支撑杆5三者的连接方式不同。具体而言，结合图25至图27所示，横杆4的第一端部通过一个万向旋转接头32可转动地连接于挑檐杆3上的固定座30，支撑杆5的第二端部通过枢轴a3可转动地连接于固定座30。
无论是采用上述示例的三种连接方式中的哪种，挑檐杆3在折叠状态时，挑檐杆3的下端部、横杆4的第二端部及支撑杆5的第一端部和腿杆1相互靠拢。
