Description

一种适用于避震车的避震车架 技术领域
本发明涉及碳纤维自行车技术领域，尤其涉及一种适用于避震车的避震车架。
背景技术
传统的避震车架的避震结构一般是在下管的内侧设置一个前部支撑座，在座管的内侧设置一个中部支撑座，在外延部的后上侧设置一个后部支撑座；中部支撑座与连杆的底端铰接，连杆的顶端与避震器的后端、后上叉的前端铰接，然后避震器的前端与前支撑座铰接，后下叉的前端与后部支撑座铰接，从而实现避震效果。
避震原理：通过后上叉在震动时向前下方进行冲击，从而带动连杆向前下方转动，连杆再驱动避震器进行弹性压缩，从而将震动产生的冲击力抵消掉，以此来达到避震效果。
现有技术：在后上叉向前下方进行冲击时，由于后上叉与后下叉之间的后端夹角会发生缩小，因此现有技术中通常只能将后上叉的后端与后下叉的后端进行铰接，从而避免后上叉与后下叉的连接部位发生折断。
缺点：采用铰接的后叉支架的强度比采用一体式连接的后叉支架的强度低，从而降低了避震车架的整体安全系数。
发明内容
本发明的目的在于提供一种适用于避震车的避震车架，以解决现有避震车架的后叉支架的强度较低的技术问题。
为了实现上述目的，本发明的技术方案提供了一种适用于避震车的避震车架，包括前三角架、后叉支架，所述前三角架位于所述后叉支架的前方；所述前三角架的内侧设有第一支撑座、第二支撑座，所述前三角架的外侧设有第三支撑座，所述第一支撑座、所述第二支撑座、所述第三支撑座向后下方依次分布；所述第 二支撑座与第一连杆的底端铰接，所述第一连杆的顶端与第二连杆的前端、避震器的后端铰接；所述第二连杆的后端与所述后叉支架的前上端铰接，所述后叉支架的前下端与所述第三支撑座铰接，所述避震器的前端与所述第一支撑座铰接。

进一步地，左侧的所述后上叉、所述后下叉的前端分别与左侧的竖板的上下两端一体成型，右侧的所述后上叉、所述后下叉的前端分别与右侧的竖板的上下两端一体成型，左右两侧的所述竖板的分别与第二水平板的左右两端一体成型，所述第二水平板位于所述座管的后方。
进一步地，所述第二连杆的数量包括两个，左右两侧的所述后上叉的前端还分别与两个所述第二连杆的后端铰接，两个所述第二连杆的前端分别与所述第一连杆的顶端的左右两侧铰接。

进一步地，所述缺口内设有连接块，所述连接块的后端设有U型槽口，所述座管位于所述U型槽口内；所述U型槽口的左右两侧板分别与左右两侧的所述折弯板的内侧铰接，所述连接块的前端与所述避震器的后端固定连接。
综上所述，运用本发明的技术方案，具有如下的有益效果：本发明的结构设计合理，通过第二连杆的前后两端分别与第一连杆的顶端、后叉支架的前上端铰接，从而在后叉支架遇到震动的情况时，可以通过第二连杆来将后叉支架的冲击力传递到第一连杆的顶端，从而驱动第一连杆向前下方转动，进而驱动避震器进行弹性收缩，从而达到避震效果。由此分析可知，本发明通过将后叉支架的铰接点前移到后叉支架与第一连杆的连接处，从而能够利用第二连杆的转动来避免后叉支架自身的夹角发生缩小，从而使得后叉支架的连接点可以使用除了铰接以外的连接方式，比如一体式连接或可拆卸固定连接等方式，从而在实现避震效果的同时大大提高了后叉支架的强度，从而提高了避震车架的安全系数、避震车的避震效果与避震车的舒适度、稳定性。

具体地，左侧的后上叉201、后下叉202的前端分别与左侧的竖板203的上下两端一体成型，右侧的后上叉201、后下叉202的前端分别与右侧的竖板203的上下两端一体成型，左右两侧的竖板203的分别与第二水平板205的左右两端一体成型，第二水平板205位于座管103的后方，作用：竖板提高后叉支架的支撑强度，第二水平板可以与座管的后侧进行限位配合，从而防止后叉支架过度向 前运动。
具体地，第二连杆4的数量包括两个，左右两侧的后上叉201的前端还分别与两个第二连杆4的后端铰接，两个第二连杆4的前端分别与第一连杆3的顶端的左右两侧铰接，作用：左右两侧铰接可以提高受力平衡。
具体地，左右两侧的后上叉201的前端分别设有开口朝向前上方的L型槽206，两个第二连杆4的后端分别与左右两侧的L型槽206的内侧壁铰接，作用：L型槽可以对后上叉与第二连杆之间的转动角度进行限制，从而使其转动在合理的区间。
具体地，第一连杆3的顶端设有缺口，缺口的左右两侧分别设有向后延伸的折弯板301，座管103位于左右两侧的折弯板301之间，两个第二连杆4的前端分别与左右两侧的折弯板301的外侧铰接，作用：缺口、折弯板的设置可以使得第一连杆受到前后左右方向的限位，从而防止第一连杆的位置在运动后逐渐发生偏离。
具体地，缺口内设有连接块5，连接块5的后端设有U型槽口，座管103位于U型槽口内；U型槽口的左右两侧板分别与左右两侧的折弯板301的内侧铰接，连接块5的前端与避震器的后端固定连接，作用：设置连接块一方面可以方便第一连杆与避震器的连接，另一方面可以通过U型槽口与座管的左右限位配合，对避震器的后端形成左右方向的限位，从而防止其运动后发生偏离。
综上所述，本发明具有如下的有益效果：
(1)通过设置第二连杆，从而在实现避震效果的同时大大提高了后叉支架的强度，从而提高了避震车架的安全系数。
(2)通过第一连杆、第二连杆、连接块之间的相互铰接，从而在后期更换损坏的零件方面更加方便，更加具有经济性。
(3)通过以上(1)、(2)点的设计，使避震车的整体避震效果、舒适度与稳定性得以更加出色。
以上所述是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本发明的保护范围。
