Abstract

A bolt mounting structure for a vehicle roof battery, comprising: a pre-buried plate (300) fixed to a vehicle roof (200); a mounting plate (400) fixed on one side of the pre-buried plate distant from the vehicle roof; and a mounting bolt (100), comprising: a screw rod (110) and a head portion (120), the screw rod sequentially penetrating through the mounting plate, the pre-embedded plate, and the vehicle roof, at least part of the screw rod extending out of the vehicle top, and the head portion being fixedly connected to the mounting plate. The mounting plate and the pre-buried plate of the bolt mounting structure are fixedly connected, and the head portion and the mounting plate are welded; moreover, the contact area between the mounting plate and the pre-buried plate is large enough, so that even in the case of sudden acceleration or sudden deceleration of a vehicle, i.e., in the case of a large slip tendency of a battery pack, the abutting of the mounting plate and the pre-buried plate can also counteract the force of sliding the battery pack, and the stress of the mounting plate and the pre-buried plate in a unit area is very small.

Description

一种用于车顶电池的螺栓安装结构A bolt mounting structure for roof battery 技术领域technical field
本发明涉及螺栓固定技术领域，尤其涉及一种用于车顶电池的螺栓安装结构。The invention relates to the technical field of bolt fixing, in particular to a bolt installation structure for a roof battery.
背景技术Background technique
现有技术中，采用螺栓固定的结构一般都是先打孔，而后放置螺栓到打好的孔，最后拧紧螺帽即可固定，这样的螺栓固定方式最常见，也最简单。In the prior art, the bolt-fixed structure generally involves first punching holes, then placing the bolts in the punched holes, and finally tightening the nut to fix it. This bolt-fixing method is the most common and simplest.
但在某些特殊的使用场景下，如新能源公交车等，需要在车顶处安装固定电池组，通常电池组采用螺栓固定，但如果用螺栓直接打孔固定的话，由于电池质量较大，螺栓连接处受力较大，易产生松动，导致电池组在随车行驶的过程中晃动，甚至发生电池组掉落的危险。However, in some special usage scenarios, such as new energy buses, it is necessary to install and fix the battery pack on the roof. Usually the battery pack is fixed with bolts, but if the bolts are directly punched and fixed, due to the large battery quality, The bolt connection is subject to large force and is prone to loosening, which causes the battery pack to shake during the process of traveling with the vehicle, and even the danger of the battery pack falling.
究其原因，是因为电池组随着汽车加速或减速的过程中会产生相对于车顶面前后滑移的趋势，而螺栓中的螺杆是垂直于车顶表面固定的，因此此时主要受力的部件是螺栓中的螺帽；又由于螺帽与车顶表面的接触面积很小，导致车顶的单位面积受力很大，螺帽在电池组的带动下易造成车顶的变形，进而螺栓连接处产生松动，以至于发生一系列的危险。The reason is that the battery pack will tend to slip relative to the front and rear of the roof as the car accelerates or decelerates, and the screws in the bolts are fixed perpendicular to the roof surface, so the main force is at this time. The main component is the nut in the bolt; and because the contact area between the nut and the roof surface is very small, the unit area of the roof is subject to great force, and the nut is easily driven by the battery pack to cause deformation of the roof, and then The bolted joints become loose, so that a series of dangers occur.
发明内容SUMMARY OF THE INVENTION

优选地，所述安装板与所述预埋板之间贯穿有若干铆钉，所述铆钉垂直于所述安装板或/和预埋板。Preferably, a plurality of rivets pass through between the mounting plate and the pre-embedded plate, and the rivets are perpendicular to the mounting plate or/and the pre-embedded plate.

与现有技术相比，本发明至少具有以下有益效果：Compared with the prior art, the present invention at least has the following beneficial effects:
本申请中，通过加装安装板与头部焊接固定，使得螺栓的头部与安装板形成一个整体，伸出车顶的部分螺杆用于固定电池组。当电池组随着汽车行驶而具有相对于车顶表面滑移的趋势时，螺杆受力将此趋势传递至头部，头部连带安装板与预埋板相抵顶同时卸掉这个力，以此保护了螺栓连接的强度。进一步的，由于安装板与预埋板接触面积足够大，使得即使是在汽车急加速或急减速的情况下，也就是电池组滑移的趋势较大时，安装板与预埋板相抵顶也可卸掉这个使电池组滑移的力，单位面积内安装板与预埋板的受力很小。因此，设置安装板和预埋板也可以保护车顶不变形，延长车顶的使用寿命，同时增强了车顶电池组的安全性。In the present application, the head of the bolt is welded and fixed with the head, so that the head of the bolt and the installation plate form a whole, and the part of the screw extending out of the roof is used to fix the battery pack. When the battery pack has a tendency to slip relative to the roof surface as the car travels, the force of the screw transmits this tendency to the head, and the head, together with the mounting plate and the embedded plate, abut against the pre-embedded plate and release this force, thereby The strength of the bolted connection is preserved. Further, since the contact area between the mounting plate and the embedded plate is large enough, even in the case of rapid acceleration or rapid deceleration of the car, that is, when the tendency of the battery pack to slip is large, the mounting plate and the embedded plate will abut against each other. The force that makes the battery pack slip can be removed, and the force on the mounting plate and the embedded plate per unit area is very small. Therefore, arranging the mounting plate and the pre-embedded plate can also protect the roof from deformation, prolong the service life of the roof, and at the same time enhance the safety of the roof battery pack.

具体实施方式detailed description
以下是本发明的具体实施例并结合附图，对本发明的技术方案作进一步的描述，但本发明并不限于这些实施例。The following are specific embodiments of the present invention and combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
请参照图1，本发明公开了一种用于车顶电池的螺栓安装结构，包括：Referring to FIG. 1, the present invention discloses a bolt mounting structure for a roof battery, including:
预埋板300，其与车顶200固定；The embedded board 300, which is fixed with the roof 200;
安装板400，其固定于所述预埋板300远离车顶200的一侧；an installation plate 400, which is fixed on the side of the embedded plate 300 away from the vehicle roof 200;
安装螺栓100，包括：螺杆110和头部120，所述螺杆110依次穿过安装板400、预埋板300及车顶200，至少有部分所述螺杆110伸出车顶200，且所述头部120与所述安装板400固定连接。The mounting bolt 100 includes: a screw 110 and a head 120, the screw 110 passes through the mounting plate 400, the embedded plate 300 and the roof 200 in sequence, at least part of the screw 110 protrudes from the roof 200, and the head The part 120 is fixedly connected with the mounting plate 400 .
本实施例中，通过加装安装板400与头部120焊接固定，使得螺栓的头部120与安装板400形成一个整体，伸出车顶200的部分螺杆110用于固定电池组。当电池组随着汽车行驶而具有相对于车顶200表面滑移的趋势时，螺杆110受力将此趋势传递至头部120，头部120连带安装板400与预埋板300相抵顶同时卸掉这个力，以此保护了螺栓连接的强度。进一步的，由于安装板400与预埋板300接触面积足够大，使得即使是在汽车急加速或急减速的情况下，也就是电池组滑移的趋势较大时，安装板400与预埋板300相抵顶也可卸掉这个使电池组滑移的力，单位面积内安装板400与预埋板300的受力很小。因此，通过设置安装板400和预埋板300也可以保护车顶200不变形，延长车顶200的使用寿命，同时增强了车顶200电池组的安全性。In this embodiment, the mounting plate 400 is welded and fixed to the head 120, so that the head 120 of the bolt and the mounting plate 400 form a whole, and part of the screw rod 110 extending out of the roof 200 is used to fix the battery pack. When the battery pack has a tendency to slip relative to the surface of the roof 200 as the vehicle runs, the screw 110 is forced to transmit this tendency to the head 120, and the head 120, together with the mounting plate 400 and the embedded plate 300, abut against the embedded plate 300 and unload at the same time. This force is removed, thereby preserving the strength of the bolted connection. Further, since the contact area between the mounting plate 400 and the embedded plate 300 is large enough, even in the case of rapid acceleration or rapid deceleration of the vehicle, that is, when the tendency of the battery pack to slip is large, the mounting plate 400 and the embedded plate are The force that makes the battery pack slip can also be removed when the 300 touches against each other, and the force on the mounting plate 400 and the embedded plate 300 per unit area is very small. Therefore, by arranging the mounting plate 400 and the embedded plate 300, the roof 200 can also be protected from deformation, the service life of the roof 200 can be prolonged, and the safety of the battery pack of the roof 200 can be enhanced.
所述安装板400与所述预埋板300之间贯穿有若干铆钉500，所述铆钉500垂直于所述安装板400或/和预埋板300。Several rivets 500 pass through between the installation board 400 and the embedded board 300 , and the rivets 500 are perpendicular to the installation board 400 or/and the embedded board 300 .
设置铆钉500贯穿安装板400和预埋板300可防止安装板400与预埋板300之间发生相对转动，同时还增强了安装板400与预埋板300之间的连接强度，使得安装板400与预埋板300在两两抵顶时可以卸掉更大的力，进而保护了螺栓安装的强度。Providing the rivets 500 to penetrate the mounting plate 400 and the embedded plate 300 can prevent the relative rotation between the mounting plate 400 and the embedded plate 300, and also enhance the connection strength between the mounting plate 400 and the embedded plate 300, so that the mounting plate 400 When the embedded boards 300 are abutted against each other, a larger force can be removed, thereby protecting the strength of the bolt installation.
进一步的，采用铆钉500固定安装板400和预埋板300，避免了安装板400与预埋板300的现场焊接，提高作业效率，同时降低了现场作业的难度。Further, the use of rivets 500 to fix the mounting plate 400 and the embedded plate 300 avoids on-site welding of the mounting plate 400 and the embedded plate 300 , improves work efficiency, and reduces the difficulty of on-site operations.
所述车顶200开设有若干铆钉孔210，所述铆钉500由铆钉孔210进入依次穿过预埋板300及安装板400。The roof 200 is provided with a plurality of rivet holes 210 , and the rivets 500 enter through the rivet holes 210 and pass through the embedded plate 300 and the mounting plate 400 in sequence.
所述铆钉孔210填充有密封胶600。The rivet holes 210 are filled with sealant 600 .
铆钉孔210填充密封胶600的作用在于，防止雨水从铆钉孔210流至车内，同时还可以防止铆钉500生锈腐蚀。The function of filling the rivet hole 210 with the sealant 600 is to prevent rainwater from flowing into the vehicle from the rivet hole 210 and also to prevent the rivet 500 from rusting and corroding.
车顶200与所述预埋板300焊接固定，且车顶200与所述预埋板300之间填充有密封胶600。The roof 200 and the embedded board 300 are welded and fixed, and a sealant 600 is filled between the roof 200 and the embedded board 300 .
所述预埋板300与所述安装板400之间填充有密封胶600。A sealant 600 is filled between the embedded board 300 and the mounting board 400 .
本实施例的具体实施步骤及工作原理如下：The specific implementation steps and working principle of this embodiment are as follows:
首先焊接好安装板400与安装螺栓100，同时将铆钉500沉入预埋板300，而后将安装板400与预埋板300焊接固定，与此同时若干铆钉500穿过安装板400，安装螺栓100的螺杆110由下而上的依次穿过预埋板300及车顶200，且螺杆110伸出车顶200用于固定电池组。安装好后，在汽车行驶过程中，电池组前后左右都可能具有滑移的趋势，也就使得螺杆110会具有倾斜的趋势，进而头部120连带安装板400与预埋板300抵顶，最终卸掉这个力。以此保护车顶200不产生变形，避免了因螺杆110倾斜带动头部120直接与车顶200抵顶，造成螺栓连接处松动，车顶200变形，电池组暴露甚至掉落等一系列危险事故。First, weld the mounting plate 400 and the mounting bolts 100, sink the rivets 500 into the embedded plate 300, and then weld and fix the mounting plate 400 and the embedded plate 300. At the same time, a number of rivets 500 pass through the mounting plate 400, and the mounting bolts 100 The screw rods 110 pass through the embedded plate 300 and the roof 200 sequentially from bottom to top, and the screw rods 110 extend out of the roof 200 for fixing the battery pack. After installation, during the driving process of the car, the battery pack may have a tendency to slip in the front, rear, left and right sides, which makes the screw 110 tend to incline, and then the head 120 together with the mounting plate 400 and the embedded plate 300 abut against the top. Remove this force. In this way, the roof 200 is protected from deformation, and a series of dangerous accidents, such as the loosening of the bolt connection, the deformation of the roof 200, the exposure of the battery pack and even the falling of the battery pack, are avoided due to the inclination of the screw 110 to drive the head 120 to directly touch the roof 200. .
本文中所描述的具体实施例仅仅是对本发明精神作举例说明。本发明所属技术领域的技术人员可以对所描述的具体实施例做各种各样的修改或补充或采用类似的方式替代，但并不会偏离本发明的精神或者超越所附权利要求书所定义的范围。The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention pertains can make various modifications or additions to the described specific embodiments or substitute in similar manners, but will not deviate from the spirit of the present invention or go beyond the definitions of the appended claims range.
