DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Based on the technical issues raised by the above prior art regarding the oil injection efficiency of electric vehicle front forks, please refer to Figure 1-Figure 5 The utility model provides an oil filling device for an electric vehicle front fork. The first spring 43 and the second spring 44 are connected on the same center line of the two fixing blocks 41 in the fixing mechanism 4. The device can be used to fix and clamp the electric vehicle front forks of various spacing specifications. The oil filling mechanism 6 uses two integrally formed oil passage chambers 62 on the oil inlet groove 61 and a tilting block 66 connected to the upper open ends of the two oil passage chambers 62. After the lubricating oil is pumped into the oil inlet groove 61 by an oil pump 67, the oil can enter the oil passage chamber 62 through the low inclined surfaces on both sides of the tilting block 66, thereby achieving the effect of synchronously delivering lubricating oil to the bottom barrels on both sides of the electric vehicle front fork, thereby improving the oil filling efficiency of the electric vehicle front fork. The oil filling device is to separate the oil storage chamber 2 and the operating chamber 3 on the box body 1 by a partition. The oil storage chamber 2 stores lubricating oil for filling the bottom barrel of the electric vehicle front fork.
[0026] Among them, in order to solve the problem of fixing the bottom barrel of the electric vehicle front fork, a fixing mechanism 4 for fixing the bottom barrel of the electric vehicle front fork is installed on one side of the inner cavity of the operating chamber 3 in the technical solution. Its specific structure is composed of two fixing blocks 41 slotted and installed on one side wall of the inner cavity of the operating chamber 3, and two clamping plates 42 are relatively installed at the opening position on the fixing block 41, and the two clamping plates 42 are rotatably connected to the outer ends of the openings on the fixing block 41 through torsion springs. By utilizing the elasticity of the torsion spring, the spacing between the two clamping plates 42 can be adjusted in time, which is suitable for electric vehicle front forks of various specifications. The first spring 43 is horizontally welded to the end faces of the two fixing blocks 41 that are close to each other, and the second spring 44 is welded to the end faces of the two fixing blocks 41 that are separated, and the separated ends of the second springs 44 on both sides are welded to the side of the inner cavity of the operating chamber 3, and the bottom barrel of the electric vehicle front fork to be filled with oil is placed in the notch opened on the upper end face of the fixing block 41, and the clamping plates 42 connected with the torsion springs are used to limit the bottom barrel of the electric vehicle front fork, so that the oil filling port on the bottom barrel of the electric vehicle front fork is placed on the top.
[0027] Among them, in order to facilitate the installation and removal of the oil injection mechanism 6 on the upper fixing plate 5, the upper fixing plate 5 on the fixing mechanism 4 in the technical solution is equipped with an oil injection mechanism 6 for delivering oil to the bottom barrel of the front fork of the electric vehicle. Its specific structure is an oil inlet groove 61 combined on the upper fixing plate 5, and two relatively distributed oil passage chambers 62 are integrally formed on the oil inlet groove 61. The end surface of the upper fixing plate 5 corresponds to the oil passage chamber 62 and penetrates through two through openings. Through the two through openings, the assembly of the oil injection mechanism 6 on the upper fixing plate 5 is realized. The bottom end of the oil passage chamber 62 is rotatably connected to the mesh plate 63 through a bearing. Two inserts 64 are relatively welded on the mesh plate 63. The opening is provided with a plurality of oil passage chambers 62, each of which is provided with a plurality of oil passage chambers 62. Two limiting grooves 7 are provided opposite to each other, and the limiting groove 7 is L-shaped in the inner cavity wall of the through-port. One end of the limiting groove 7 is connected to the embedding groove that matches the embedding block 64. The two embedding blocks 64 welded relatively on the mesh plate 63 rotatably connected to the lower end of the oil through-port chamber 62 are correspondingly plug-in assembled on the two limiting grooves 7 provided on the inner cavity wall of the through-port that penetrates through the upper fixed plate 5, so that the embedding block 64 is plugged into the embedding groove provided at one end of the limiting groove 7, and then the mesh plate 63 rotatably connected to the oil through-port chamber 62 is rotated so that the embedding block 64 on the mesh plate 63 is placed at the other end of the inner groove of the limiting groove 7, thereby completing the assembly of the oil filling mechanism 6 on the upper fixed plate 5.
[0028] Among them, in order to solve the problem of oil leakage during the oil filling operation, the lower end of the mesh plate 63 in the technical solution is screwed to fix the ring 65, and the ring 65 is made of a material with good adsorption properties, such as sponge. The ring 65 is covered on the outside of the oil filling port of the bottom barrel of the front fork of the electric vehicle. When the introduced lubricating oil enters the bottom barrel of the front fork of the electric vehicle, the lubricating oil leaked during the oil filling operation will be promptly absorbed by the ring 65, which helps to keep the oil filling operation neat and clean.
[0029] The oil pump 67 is installed in the middle of the oil inlet groove 61 and between the two oil passage chambers 62 in the technical scheme. The oil pump 67 is installed in the middle position of the inclined block 66. The inlet end of the oil pump 67 is connected with the oil guide pipe, and the end of the oil guide pipe is extended and arranged in the oil storage chamber 2. The lubricating oil is transported from the oil storage chamber 2 to the outside through the oil guide pipe by the oil pump 67. The outlet end of the oil pump 67 is connected with the oil guide pipe, and the end of the oil guide pipe is connected with two outlet pipes through a tee. The lubricating oil pressurized and transported by the oil pump 67 is introduced into the oil inlet groove 61 through the two outlet pipes on the tee connected at the end of the oil guide pipe, and then guided into the corresponding oil passage chambers 62 on both sides through the inclined surface of the inclined block 66, and enters the bottom tube of the front fork of the electric vehicle under the filtration of the mesh on the mesh plate 63. Since the top surface of the mesh plate 63 is provided with a concave surface, the added lubricating oil can be prevented from accumulating on the upper surface of the mesh plate 63.
[0030] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
