充电枪插座和包括该插座的充电桩Charging gun socket and charging post including the socket 技术领域Technical field
本发明涉及电动汽车充电领域，具体涉及一种充电枪插座和包括该插座的充电桩。The present invention relates to the field of electric vehicle charging, and in particular to a charging gun socket and a charging post including the socket.
背景技术Background technique
随着新能源汽车的普及，如何有效地为能量不足的新能源汽车进行能量补给成为了车主和各大厂商关注的焦点。其中，建造补能装置(如建造能够为电动汽车电池提供充电电源的充电桩)是解决上述问题的主流方案之一。以电动汽车的充电桩为例，其由于其占地面积小、使用方便等因素被广泛分布于停车场、居民小区、大型商场以及服务区等充电需求相对集中的场所。用户在使用充电桩时，只需要将充电枪从充电枪插座上拔出并插到电动汽车上的充电接口即可为电动汽车的动力电池充电，在充电结束后只需将充电枪再次插回充电枪插座中即可。With the popularization of new energy vehicles, how to effectively replenish energy for new energy vehicles with insufficient energy has become the focus of attention of car owners and major manufacturers. Among them, the construction of replenishing devices (such as the construction of charging piles capable of providing charging power for electric vehicle batteries) is one of the mainstream solutions to the above problems. Taking the charging pile of an electric vehicle as an example, it is widely distributed in parking lots, residential areas, large shopping malls, and service areas, where the charging demand is relatively concentrated due to its small footprint and convenient use. When using the charging pile, the user only needs to unplug the charging gun from the charging gun socket and plug it into the charging interface of the electric vehicle to charge the electric vehicle's power battery. After charging, just plug the charging gun back again. It can be in the charging gun socket.

首先参照图1，图1是本发明的充电枪插座的结构示意图。如图1所示，本发明的充电枪插座包括壳体1、连接板3以及若干导向结构2。其中，壳体1为筒状结构，连接板3设置(套接于外壁或者与壳体1一体成型)于筒状结构的外壁上，若干个导向结构2设置于筒状结构的内壁上并与筒状结构形成导向腔体，充电枪能够通过该导向腔体沿筒状结构的轴向伸入/退出壳体1。此外，壳体1上还设置有第一对接结构4，充电枪上对应地设置有第二对接结构(图中未示出)，在充电枪完全伸入壳体1的情形下，充电枪能够通过第一对接结构4与第二对接结构的配合连接固定插合于充电枪插座中。如第一对接结构4可以为卡槽，第二对接结构可以为与卡槽匹配连接的卡扣。Referring first to Figure 1, Figure 1 is a schematic view of the structure of a charging gun socket of the present invention. As shown in FIG. 1, the charging gun socket of the present invention comprises a housing 1, a connecting plate 3 and a plurality of guiding structures 2. The housing 1 is a cylindrical structure, and the connecting plate 3 is disposed (sleeved on or integrally formed with the outer casing 1) on the outer wall of the cylindrical structure, and the plurality of guiding structures 2 are disposed on the inner wall of the cylindrical structure and The cylindrical structure forms a guiding cavity through which the charging gun can project into/out of the housing 1 in the axial direction of the cylindrical structure. In addition, the housing 1 is further provided with a first docking structure 4, and the charging gun is correspondingly provided with a second docking structure (not shown). In the case where the charging gun fully extends into the housing 1, the charging gun can The mating connection of the first docking structure 4 and the second docking structure is fixedly inserted into the charging gun socket. For example, the first docking structure 4 may be a card slot, and the second docking structure may be a buckle that is matched with the card slot.
按照图1所示方位，充电枪插座包括大致呈圆筒状结构的壳体1(以下简称圆筒状壳体1、圆筒状结构或壳体1)，连接板3以套接的方式设置于该壳体1的外壁上。壳体1的内壁上沿壳体1的轴向(即深度方向)设置有若干个导向结构2，该若干导向结构2形成导向腔体，充电枪能够通过该导向腔体沿壳体1的深度方向伸入/退出壳体1。此外，壳体1的上部还设置有卡槽，对应的充电枪上设置有卡扣，充电枪能够通过卡扣与卡槽的匹配连接插合于壳体1中。According to the orientation shown in Fig. 1, the charging gun socket comprises a housing 1 having a substantially cylindrical structure (hereinafter referred to as a cylindrical housing 1, a cylindrical structure or a housing 1), and the connecting plate 3 is arranged in a socket manner. On the outer wall of the housing 1. A plurality of guiding structures 2 are arranged on the inner wall of the housing 1 in the axial direction (ie, the depth direction) of the housing 1, and the guiding structures 2 form a guiding cavity through which the charging gun can pass along the depth of the housing 1. The direction extends into/out of the housing 1. In addition, the upper part of the casing 1 is further provided with a card slot, and the corresponding charging gun is provided with a buckle, and the charging gun can be inserted into the casing 1 through the matching connection of the buckle and the card slot.
可以看出，通过在壳体1的内壁上设置若干个导向结构2的方式，使得在充电枪在伸入/退出充电枪插座的过程中，以充电枪的外圆周面与导向结构2之间以近似线性摩擦的方式，代替了充电枪的外圆周面和筒状结构的壳体1内壁之间的面摩擦，从而大大减小了充电枪与充电枪插座的插拔过程中存在的摩擦力，使得充电枪的插拔过程变得容易，从而改善了用户在使用充电桩时的使用体验。It can be seen that by providing a plurality of guiding structures 2 on the inner wall of the casing 1, the charging gun is inserted into and out of the charging gun socket, between the outer circumferential surface of the charging gun and the guiding structure 2 In the manner of approximate linear friction, the surface friction between the outer circumferential surface of the charging gun and the inner wall of the casing 1 of the cylindrical structure is replaced, thereby greatly reducing the frictional force during the insertion and removal of the charging gun and the charging gun socket. This makes the insertion and removal process of the charging gun easy, thereby improving the user's experience in using the charging post.
需要指出的是，上述以大致成圆筒状结构的壳体1为例描述充电枪插座的实施方式仅仅用来解释本发明的原理，并非旨在于限制本发明的保护范围。本领域技术人员能够理解的是，除了呈圆筒状的壳体1外，任何筒型的充电枪插座都可以适用于本发明。如壳体1还可以是大致为矩形或正方形的筒状结构等。相似地，第一对接结构4与第二对接结构的形式也不唯一，本领域技术人员还可以将前述的卡槽与卡扣的设置位置对调或者将卡槽与卡扣替换为其他结构形式，只要该结构形式能 够满足使充电枪在完全伸入壳体1的情形下将充电枪固定于充电枪插座的条件即可。It is to be noted that the above description of the housing 1 of the substantially cylindrical structure is exemplified to explain the principle of the present invention and is not intended to limit the scope of the present invention. It will be understood by those skilled in the art that any cylindrical charging gun socket can be adapted to the present invention, except for the cylindrical housing 1. For example, the casing 1 may also be a substantially rectangular or square tubular structure or the like. Similarly, the form of the first docking structure 4 and the second docking structure are not unique, and those skilled in the art may also reverse the aforementioned position of the card slot and the buckle or replace the card slot and the buckle with other structural forms. As long as the structural form can satisfy the condition that the charging gun is fixed to the charging gun socket with the charging gun fully extended into the casing 1.
下面参照图2和图3。其中，图2是图1的剖视示意图，图3是本图2在A处的局部放大示意图。Reference is made to Figures 2 and 3 below. 2 is a schematic cross-sectional view of FIG. 1, and FIG. 3 is a partially enlarged schematic view of FIG. 2 at A.
如图2所示，优选地，导向结构2的个数为3个，并且3个导向结构2沿圆筒状壳体1的周向以阵列的方式均匀分布于圆筒状壳体1的内壁上，如可以沿圆筒状壳体1的周向设置于圆筒状壳体1的内壁靠近充电枪伸入的一端(以下简称伸入端)。按图1所示方位，即3个导向结构2位于壳体1内壁的前端。这样设置的优点在于，靠近伸入端均布的3个导向结构2能够在充电枪与充电枪插座刚开始接触时，便从充电枪的外圆周面上的三个不同角度与充电枪的外圆周面产生均匀的线性摩擦，从而避免了充电枪***充电枪插座的过程中，由于导向结构2过少或充电枪伸入/退出壳体1的过程出现偏差等因素导致的充电枪的外圆周面与筒状结构的内壁产生的面摩擦，进而使充电枪与充电枪插座的插拔过程更顺利，提升了用户的使用体验。As shown in FIG. 2, preferably, the number of the guiding structures 2 is three, and the three guiding structures 2 are evenly distributed in an array on the inner wall of the cylindrical casing 1 in the circumferential direction of the cylindrical casing 1. For example, the inner wall of the cylindrical casing 1 may be disposed along the circumferential direction of the cylindrical casing 1 near the end from which the charging gun projects (hereinafter referred to as the projecting end). According to the orientation shown in Fig. 1, three guiding structures 2 are located at the front end of the inner wall of the casing 1. The advantage of this arrangement is that the three guiding structures 2 uniformly distributed near the extending end can be externally charged from the three different angles on the outer circumferential surface of the charging gun when the charging gun and the charging gun socket are initially in contact. The circumferential surface produces uniform linear friction, thereby avoiding the outer circumference of the charging gun caused by factors such as too little guiding structure 2 or deviation of the charging gun into/out of the housing 1 during insertion of the charging gun into the charging gun socket. The surface is rubbed against the surface generated by the inner wall of the cylindrical structure, thereby making the charging and charging gun sockets more smoothly inserted and removed, thereby improving the user experience.
当然，导向结构2的设置个数及设置位置并非一成不变，本领域技术人员可以根据具体应用场景对其做出调整，如导向结构2的设置位置还可以设置于筒状结构的中部，导向结构2的个数还可以设置为2个或4个等。并且，经发明人多次试验和反复计算和验证，导向结构2的数量设置为2个至4个为宜，导向结构2多于4个容易造成充电枪的外圆周面与导向结构2之间产生的摩擦力过大，少于2个则容易造成充电枪在伸入/退出壳体1的过程中出现偏差而产生面摩擦。也就是说，导向结构2设置的数量少于2个或多于4个的情形下，虽然仍然可以减小充电枪与充电枪插座之间的摩擦，但是这种设置方式并未使用户的体验达到最佳。Certainly, the number of the guiding structures 2 and the setting positions are not constant, and those skilled in the art can adjust them according to specific application scenarios. For example, the setting position of the guiding structure 2 can also be set in the middle of the cylindrical structure, and the guiding structure 2 The number can also be set to 2 or 4, and so on. Moreover, the inventors have tried and repeated calculations and verifications, and the number of the guiding structures 2 is preferably set to 2 to 4, and the guiding structure 2 is more than 4, which easily causes the outer circumferential surface of the charging gun and the guiding structure 2 to be The friction generated is too large, and less than two are likely to cause deviation of the charging gun during the process of extending into/out of the casing 1 to cause surface friction. That is to say, in the case where the number of the guiding structures 2 is less than two or more than four, although the friction between the charging gun and the charging gun socket can still be reduced, this setting does not make the user experience. Get the best.
继续参照图2，导向结构2包括导向主体21，导向主体21固定于圆筒状壳体1的内壁上。优选地，导向主体21的伸入端具有斜面22，该斜面22朝向充电枪退出的方向设置，并且该斜面22与导向主体21的连接处设置有第一倒圆角，即斜面22与导向主体21通过圆弧平滑过渡。如图2所示方位，3个导向结构2的斜面22形成了朝向壳体1前方的“喇叭状”结构。可以看出，通过在导向主体21设置斜面22的方式，使得导向结构2能够在充电枪伸入壳体1的过程中起到导向的作用， 而斜面22与导向主体21之间的圆弧平滑过渡的设置方式，又使得在导向结构2的导向过程中充电枪沿斜面22过渡到导向主体21的过程更加平滑，进一步改善了用户体验。参照图3，进一步优选地，经发明人多次试验和反复验证，斜面22与壳体1内壁之间的夹角以不大于15°的设置方式为佳(即图3中的角α)。这样的设置方式既保证了导向结构2在充电枪在伸入壳体1的过程中起到良好的导向作用，又使得充电枪在导向结构2的导向下能够平滑的从斜面22过渡到导向主体21上。当然，上述斜面22的设置方式和设置角度并非固定不变，本领域技术人员还能够对其灵活调整，以便将本发明应用于更加具体的应用场景。With continued reference to FIG. 2, the guide structure 2 includes a guide body 21 that is fixed to the inner wall of the cylindrical casing 1. Preferably, the protruding end of the guiding body 21 has a slope 22 which is disposed toward the direction in which the charging gun is withdrawn, and the joint of the inclined surface 22 and the guiding body 21 is provided with a first round, that is, the inclined surface 22 and the guiding body 21 smooth transition through the arc. In the orientation shown in Figure 2, the beveled faces 22 of the three guiding structures 2 form a "flare" configuration towards the front of the housing 1. It can be seen that by providing the inclined surface 22 in the guiding body 21, the guiding structure 2 can play a guiding role in the process of the charging gun extending into the casing 1, and the arc between the inclined surface 22 and the guiding body 21 is smooth. The arrangement of the transitions further makes the process of transitioning the charging gun along the ramp 22 to the guiding body 21 during the guiding process of the guiding structure 2 smoother, further improving the user experience. Referring to Fig. 3, it is further preferred that the inventors have repeatedly tested and repeatedly verified that the angle between the inclined surface 22 and the inner wall of the casing 1 is preferably not more than 15 (i.e., the angle α in Fig. 3). This arrangement ensures that the guiding structure 2 plays a good guiding role in the process of the charging gun extending into the casing 1, and enables the charging gun to smoothly transition from the inclined surface 22 to the guiding body under the guidance of the guiding structure 2. 21 on. Of course, the setting manner and the setting angle of the above-mentioned inclined surface 22 are not fixed, and those skilled in the art can also flexibly adjust the same to apply the present invention to a more specific application scenario.
进一步参照图2，优选地，导向结构2沿圆筒状壳体1的轴向长度不小于壳体1在该方向上长度的1/2，当然其长度理论上也不大于圆筒状壳体1在轴向的总长度。也就是说，导向结构2在轴向的长度应当介于壳体1深度的1/2与壳体1的总深度之间。这样设置的好处在于，导向结构2的长度不小于壳体1深度的一半使得在导向结构2对充电枪进行导向的过程中能够保证足够的导向长度，而导向结构2的长度不大于壳体1的总深度又使得在保证足够的导向长度之后，不仅省去了大于导向长度那部分导向主体21产生的额外的摩擦力，而且也使得充电枪伸入/退出充电枪插座的过程更加顺利。With further reference to FIG. 2, preferably, the length of the guiding structure 2 along the axial direction of the cylindrical casing 1 is not less than 1/2 of the length of the casing 1 in this direction, and of course the length is not theoretically larger than the cylindrical casing. 1 total length in the axial direction. That is to say, the length of the guiding structure 2 in the axial direction should be between 1/2 of the depth of the casing 1 and the total depth of the casing 1. The advantage of this arrangement is that the length of the guiding structure 2 is not less than half the depth of the housing 1 so that a sufficient guiding length can be ensured during the guiding of the charging structure by the guiding structure 2, and the length of the guiding structure 2 is not greater than the housing 1 The total depth, in turn, allows for an additional frictional force generated by the portion of the guide body 21 that is greater than the guide length after the sufficient length of the guide is secured, and which also makes the charging gun extend into/out of the charging gun socket more smoothly.
优选地，导向结构2沿圆筒状壳体1的厚度(径向)不小于壳体1在该方向上厚度的1/2，并且不大于壳体1在该方向上的厚度。也就是说，导向结构2的在径向的高度介于壳体1厚度的1/2与壳体1的总厚度之间。这样设置的好处在于，导向结构2的高度不小于壳体1厚度的1/2使得在导向结构2对充电枪进行导向的过程中能够保证定位的准确，而导向结构2的高度不大于圆筒状壳体1的总厚度又使得在保证定位的准确下，避免了由于高度设置的过高而导致的充电枪与导向结构2之间产生过大的摩擦力而影响***的顺利性。Preferably, the thickness (radial direction) of the guide structure 2 along the cylindrical casing 1 is not less than 1/2 of the thickness of the casing 1 in this direction, and is not greater than the thickness of the casing 1 in this direction. That is, the height of the guide structure 2 in the radial direction is between 1/2 of the thickness of the casing 1 and the total thickness of the casing 1. The advantage of this arrangement is that the height of the guiding structure 2 is not less than 1/2 of the thickness of the housing 1 so that the positioning can be ensured accurately during the guiding of the charging structure by the guiding structure 2, and the height of the guiding structure 2 is not larger than the cylinder The total thickness of the casing 1 in turn makes it possible to avoid excessive friction between the charging gun and the guiding structure 2 due to the excessively high height setting to ensure the smoothness of the insertion.
进一步地，为减小充电枪与导向结构2之间的摩擦，在一种更优选的实施方式中，还可以对导向主体21远离内壁的一面沿导向主体21的轴向进行第二倒圆角设置，该设置能够进一步减小充电枪伸入/退出壳体1过程中的摩擦力。这样一来，在充电枪伸入/退出充电枪插座的过程中，充电枪的外圆周面与导向主体21的接触更加接近于面与线的接触， 从而进一步减小了充电枪与充电枪插座插拔过程中的摩擦力，使得充电枪的插拔过程更加轻松、顺利，更进一步地改善了用户的使用体验。Further, in order to reduce the friction between the charging gun and the guiding structure 2, in a more preferred embodiment, the second side of the guiding body 21 in the axial direction of the guiding body 21 may be further performed on the side of the guiding body 21 away from the inner wall. It is provided that this arrangement can further reduce the frictional force during the insertion of the charging gun into/out of the housing 1. In this way, during the process of the charging gun extending into/out of the charging gun socket, the contact between the outer circumferential surface of the charging gun and the guiding body 21 is closer to the surface-to-line contact, thereby further reducing the charging gun and the charging gun socket. The friction during the insertion and removal process makes the insertion and removal process of the charging gun easier and smoother, and further improves the user experience.
本发明还提供了一种充电桩，该充电桩主要包括充电枪以及前述带有导向结构2的充电枪插座，充电枪插座通过连接板3与充电桩固定连接。由于在将充电枪***充电枪插座的过程中，与充电枪直接接触的是若干个导向结构2，因此充电枪的外缘尺寸应当与由若干个导向结构2形成的导向腔体相匹配。在将充电枪完全伸入充电枪插座后，充电枪通过卡槽与卡扣之间的配合实现了其与充电桩的固定连接。The invention also provides a charging pile, which mainly comprises a charging gun and the aforementioned charging gun socket with the guiding structure 2, and the charging gun socket is fixedly connected with the charging pile through the connecting plate 3. Since a plurality of guiding structures 2 are in direct contact with the charging gun during insertion of the charging gun into the charging gun socket, the outer edge of the charging gun should be sized to match the guiding cavity formed by the plurality of guiding structures 2. After the charging gun is fully extended into the charging gun socket, the charging gun realizes a fixed connection with the charging post through the cooperation between the card slot and the buckle.
上述优选的实施方式，充电枪插座主要包括圆筒状壳体1，壳体1的外壁上套接有连接板3，壳体1的内壁上设置有若干个导向结构2。其中，导向结构2优选地为3个，并且3个导向结构2均布于壳体1的内壁上。导向结构2包括导向主体21，导向主体21还具有斜面22，该斜面22与导向主体21之间通过圆弧平滑过渡。此外，导向结构2沿充电枪插座的深度方向长度不小于壳体1深度的1/2，导向结构2沿充电枪插座径向方向的高度不小于壳体1厚度的1/2，并且导向主体21在远离内壁的一面还进行倒圆角处理。通过上述导向结构2的优选设置方式，使得充电枪和充电枪插座在插合过程中的摩擦方式由目前的面与面之间的面摩擦优化为接近于面与线之间的线性摩擦，从而大大降低了插拔难度，改善了用户体验。In the above preferred embodiment, the charging gun socket mainly comprises a cylindrical casing 1. The outer wall of the casing 1 is sleeved with a connecting plate 3, and the inner wall of the casing 1 is provided with a plurality of guiding structures 2. Therein, the guiding structures 2 are preferably three, and the three guiding structures 2 are evenly distributed on the inner wall of the casing 1. The guiding structure 2 comprises a guiding body 21, which also has a bevel 22, which smoothly transitions with the guiding body 21 by means of an arc. Further, the length of the guiding structure 2 in the depth direction of the charging gun socket is not less than 1/2 of the depth of the housing 1, and the height of the guiding structure 2 in the radial direction of the charging gun socket is not less than 1/2 of the thickness of the housing 1, and the guiding body 21 is also rounded on the side away from the inner wall. Through the preferred arrangement of the guiding structure 2 described above, the friction mode of the charging gun and the charging gun socket during the insertion process is optimized from the surface friction between the surface to the surface to be close to the linear friction between the surface and the line, thereby It greatly reduces the difficulty of plugging and unplugging and improves the user experience.
此外，应该指出的是，虽然本发明的附图是以完全相同的3个导向结构2进行描述的，但这种描述并非旨在限制本发明的保护范围。本领域技术人员还能够理解的是，本发明的充电枪插座包括的导向结构2并非只限于3个完全相同的导向结构2，在不偏离本发明原理的情形下，导向结构2的数量和形式还可以做出任意形式的调整，以便其能更好地适应不同的应用场景。如导向结构2还可以设置为4个，并且4个导向结构2分别具有不同的轴向长度、径向高度、斜面22与内壁的夹角角度等。Moreover, it should be noted that although the drawings of the present invention are described in terms of three identical guiding structures 2, this description is not intended to limit the scope of the present invention. It will also be understood by those skilled in the art that the charging gun socket of the present invention includes the guiding structure 2 not limited to three identical guiding structures 2, and the number and form of the guiding structures 2 without departing from the principle of the present invention. Any form of adjustment can also be made so that it can better adapt to different application scenarios. For example, the guiding structure 2 can also be set to four, and the four guiding structures 2 respectively have different axial lengths, radial heights, angles of the inclined faces 22 and the inner wall, and the like.
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。Heretofore, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings, but it is obvious to those skilled in the art that the scope of the present invention is obviously not limited to the specific embodiments. Those skilled in the art can make equivalent changes or substitutions to the related technical features without departing from the principles of the present invention, and the technical solutions after the modifications or replacements fall within the scope of the present invention.
