Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle accessories, in particular to a filter for new energy vehicles. Background Technique

[0002] The fuel filters used in existing fuel vehicles, such as a filter seat of a vehicle filter disclosed on the Chinese Patent website with the publication number CN207018123U, mainly filter impurities such as iron oxide, dust, and moisture in the fuel. Although there is no need to filter fuel in new energy vehicles, since the essential difference between new energy vehicles and fuel vehicles is only in the power source, many other components are the same, such as:

[0003] The battery cooling system in the battery cooling system of new energy vehicles may require a filter to prevent impurities from entering, ensure the cleanliness of the coolant, and maintain the battery temperature stable. The motor and electronic control system may be equipped with filters to filter impurities in the coolant or lubricating oil to ensure the normal operation of the system. Since the entire production technology of existing fuel vehicles is already very mature, the filters on fuel vehicles can be directly used for filtering the battery coolant or lubricating oil in new energy vehicles.

[0004] However, since the impurities in fuel are still different from those in coolant or lubricating oil, especially the impurities in lubricating oil, because lubricating oil is used for moving lubrication between various metal components, there will be many metal impurities when the lubricating oil passes through the filter. Especially when a new vehicle is just starting to be used, more metal impurities will be generated during the initial running-in of various metal moving components. At this time, if you want to remove the metal impurities in the filter more thoroughly during the initial maintenance, according to the design of existing fuel vehicle filters, the entire filter needs to be removed for in-depth cleaning, which will greatly increase the maintenance time and cost. Moreover, frequent disassembly and assembly of the filter will also reduce the sealing performance of each connection port. Content of the Utility Model

[0005] Based on the existing technical problems, the utility model provides a filter for new energy vehicles.

[0006] A filter for new energy vehicles provided by the utility model includes a support. A feed channel communicating with the cavity on the back of the support is horizontally arranged at the top of the support. A discharge channel parallel to the feed channel is also arranged in the middle of the support. A front cavity is provided on the front of the support. An arc-shaped channel communicating with the discharge channel is provided at the inner bottom wall of the bottom of the front cavity.

[0007] An elastic filtering mechanism is arranged inside the arc-shaped channel. When the liquid or gas to be filtered is pressed into the arc-shaped channel, solid particles are intercepted by the elastic filtering mechanism to achieve the filtering action.

[0008] The elastic filtering mechanism includes a filtering spherical shell with a diameter between the top width and the bottom width of the cross-section of the arc-shaped channel, and spring pins are fixedly connected to the outer surface of the filtering spherical shell.

[0009] At the lowest point of the arc-shaped channel, a sedimentation hole is formed in an arc shape towards the front direction of the support. The elastic filtering mechanism is elastically extruded by the inner wall of the sedimentation hole and slides into the arc-shaped channel, then elastically resets and unfolds along the inner wall shape of the arc-shaped channel, and finally the elastic filtering mechanism is sealed in the arc-shaped channel and the sedimentation hole through a sealing bolt.

[0010] Preferably, the top width of the cross-section of the arc-shaped channel is smaller than the bottom width.

[0011] Through the above technical solution, setting the width to be narrower at the top and wider at the bottom can prevent the elastic filtering mechanism from being pressed into the outlet by liquid or gas, thus affecting the normal entry and exit of liquid or gas.

[0012] Preferably, the filtering spherical shell is formed by screwing two hemispheres made of metal wire meshes together, and an anti-backflow cone with pores smaller than those of the metal wire mesh is fixedly connected to the inner wall of the filtering spherical shell.

[0013] Through the above technical solution, the anti-backflow cone can prevent the particulate matter that has entered the interior of the filtering spherical shell from being carried away by the flowing liquid or gas.

[0014] Preferably, a magnetic adsorption ball for magnetically adsorbing metal particulate matter is movably arranged inside the filtering spherical shell, and accumulation grooves are formed on the surface of the magnetic adsorption ball.

[0015] Through the above technical solution, the magnetic adsorption ball can adsorb the metal particulate matter, and the accumulation grooves can provide sufficient accumulation volume for the metal particulate matter.

[0016] Preferably, the difference in the lengths of the two ends of the spring pin is greater than the diameter of the filtering spherical shell.

[0017] Through the above technical solution, the spring pin can elastically press the filtering spherical shell against the inner wall of the arc-shaped channel, so that it is stable in the arc-shaped channel and prevent noise problems caused by bumps during vehicle driving.

[0018] Preferably, a steel wire rope is fixedly connected to the middle of the bottom end of the spring pin, a wave bead is fixedly installed at the bottom of the steel wire rope, and the outer end of the wave bead is fixedly installed on the inner end of the sealing bolt.

[0019] Through the above technical solution, the wave bead can prevent the problem that the spring pin rotates together when the sealing bolt rotates.

[0020] The beneficial effects of the present utility model are:

[0021] By setting up an elastic filtering mechanism, the remaining space at the bottom of the support can be fully utilized to filter out particulate impurities in the liquid or gas to be filtered. The pressure relief port or air vent originally set in the outlet in the prior art is improved and moved to the bottom of the support. In this way, not only can the filtering effect be achieved, but also the fuel vehicle filter and the new energy vehicle filter can be distinguished from the appearance through this improvement. At the same time, the overall manufacturing process and die-casting mold do not need to be greatly modified, and only an arc-shaped channel communicating with the bottom of the outlet needs to be opened in the subsequent process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] Referring to Figures 1-6 , a new energy vehicle filter, as Figures 2-3As shown in the figure, it includes a support 1. A feed channel 3 communicating with the back cavity 2 is horizontally arranged at the top of the support 1. A discharge channel 4 parallel to the feed channel 3 is also arranged in the middle of the support 1. A front cavity 5 is provided on the front of the support 1. An arc-shaped channel 6 communicating with the discharge channel 4 is provided at the inner bottom wall of the bottom of the front cavity 5. The connection part between the arc-shaped channel 6 and the discharge channel 4 is processed with an arc chamfer to avoid dead corners and bruising problems.

[0031] As Figure 1 shown, an elastic filtering mechanism is arranged inside the arc-shaped channel 6. When the liquid or gas to be filtered is pressed into the arc-shaped channel 6, solid particles are intercepted by the elastic filtering mechanism to achieve the filtering action.

[0032] In order to prevent the elastic filtering mechanism from being washed into the discharge channel 4, the width of the top of the cross-section of the arc-shaped channel 6 is set to be smaller than the width of its bottom. The width setting of being narrow at the top and wide at the bottom can prevent the elastic filtering mechanism from being pressed into the discharge channel 4 by the liquid or gas, thus affecting the normal inflow and outflow of the liquid or gas.

[0033] The elastic filtering mechanism is specifically installed as follows: A precipitation hole 7 is arc-shapedly opened at the lowest point of the arc-shaped channel 6 in the direction of the front of the support 1. The elastic filtering mechanism is elastically extruded by the inner wall of the precipitation hole and slides into the arc-shaped channel 6, then elastically resets and unfolds along the inner wall shape of the arc-shaped channel 6. Finally, the elastic filtering mechanism is sealed in the arc-shaped channel 6 and the precipitation hole through a sealing bolt 8.

[0034] As Figures 4-6 shown, the elastic filtering mechanism specifically achieves filtering as follows:

[0035] First of all, the elastic filtering mechanism includes a filtering spherical shell 61 with a diameter between the width of the top and the width of the bottom of the cross-section of the arc-shaped channel 6. In this way, the filtering spherical shell 61 can be limited in the arc-shaped channel 6, and at the same time, it will not hinder the normal flow of liquid or gas. The filtering spherical shell 61 is formed by screwing two hemispheres made of metal filter meshes together. This way of screwing two hemispheres together can not only facilitate assembly, but also the replaced filtering spherical shell 61 can be reused after cleaning, having a certain environmental protection effect, and this environmental protection effect increases with the increase in quantity, avoiding waste.

[0036] Furthermore, a backflow prevention cone 62 with pores smaller than the metal filter mesh is fixedly connected to the inner wall of the filtering spherical shell 61. The backflow prevention cone 62 can prevent the particulate matter that has entered the inside of the filtering spherical shell 61 from being taken away by the flowing liquid or gas.

[0037] Next, a magnetic attraction ball 63 for magnetically attracting metal particles is movably arranged inside the filtering spherical shell 61, and a retention groove 64 is formed on the surface of the magnetic attraction ball 63. The magnetic attraction ball 63 can adsorb the metal particles, and the retention groove 64 can provide sufficient retention volume for the metal particles. The metal particles in the particles entering from the filtering spherical shell 61 will be adsorbed by the magnetic attraction ball 63 on its surface or in the retention groove 64, and most of the non-metal particles will be left inside the filtering spherical shell 61.

[0038] Finally, in order to facilitate the installation and removal of the filtering spherical shell 61, a spring pin 65 is fixedly connected to the outer surface of the filtering spherical shell 61, and the difference in the lengths of the two ends of the spring pin 65 is greater than the diameter of the filtering spherical shell 61. This can prevent the problem of mutual extrusion when two adjacent filtering spherical shells 61 enter and exit.

[0039] The spring pin 65 can elastically press the filtering spherical shell 61 against the inner wall of the arc-shaped channel 6, so that it is stable in the arc-shaped channel 6 and prevent noise problems caused by the bumps during the vehicle driving. Moreover, after the spring pin 65 brings the filtering spherical shell 61 into the outlet channel 4, the spring pin 65 will elastically press the filtering spherical shell 61 along the inner wall of the outlet channel 4 to expand itself under the action of its own elastic force.

[0040] Furthermore, a steel wire rope 66 is fixedly connected to the middle of the bottom end of the spring pin 65, a ball 67 is fixedly installed at the bottom of the steel wire rope 66, and the outer end of the ball 67 is fixedly installed on the inner end of the sealing bolt 8. In this way, the ball 67 can prevent the problem that the sealing bolt 8 drives the spring pin 65 to rotate together when rotating, and at the same time, the screwing direction of tightening the sealing bolt is set in the same direction as the screwing direction of the steel wire rope 66 to avoid the problem that the steel wire rope 66 becomes loose after being screwed in due to accidental jamming of the ball 67.

[0041] By setting the elastic filtering mechanism, the remaining space at the bottom of the support can be fully utilized to filter the particulate impurities in the liquid or gas to be filtered, and the pressure relief port or air vent arranged at the outlet channel 4 in the prior art is improved and moved to the bottom of the support. In this way, not only the filtering effect can be achieved, but also the fuel vehicle filter and the new energy vehicle filter can be distinguished from the appearance through this improvement. At the same time, the overall manufacturing process and die-casting mold do not need to be greatly modified, and only an arc-shaped channel 6 communicating with the bottom of the outlet channel 4 needs to be opened in the subsequent process.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
