Description

Technical Field

[0001] The utility model relates to the technical field of installation structures, and more specifically, to an installation structure for an electric vehicle controller. Background Art

[0002] In the existing technology, Chinese patent document CN202222673317.4 discloses an electric vehicle controller structure. This patent designs an internal installation structure for an electric vehicle controller. During the installation process, an O-ring is used for the installation of the controller. During the process of buckling the upper cover, due to the unevenness of the O-ring, there is a possibility of leakage.

[0003] Moreover, when installing the O-ring, since there is no bearing surface on the surface of the power column, it is impossible to limit the placement process of the O-ring, thus unable to promote the placement process of the O-ring.

[0004] Secondly, there is no guiding angle at the holes of the outer shell, which causes resistance during the installation process of the O-ring, resulting in easy waste of time during the installation process and thus affecting work efficiency. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the problems existing in the prior art, the utility model provides an installation structure for an electric vehicle controller to solve the technical problem that the existing electric vehicle controller using an O-ring for sealing is prone to unstable installation as mentioned in the background art.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model provides the following technical solution: An installation structure for an electric vehicle controller includes power columns. There are five power columns. A sealing ring is detachably connected to the power columns. A housing is inserted into the power columns. A chamfering mechanism is provided on the housing.

[0009] The utility model is further arranged such that a bearing surface is provided on the power column. The sealing ring is placed on the bearing surface. The bearing surface serves as a retaining ring to axially limit the sealing ring.

[0010] The present utility model is further configured such that the sealing ring is in an X shape. Compared with an O-ring, the X-shaped sealing ring has a small contact stress and a small installation resistance. Moreover, during the process of buckling the upper cover, the phenomenon of flipping and slipping out of the O-ring will not occur. At the same time, the contact stress distribution of the X-shaped sealing ring is more uniform than that of the O-ring, and the probability of leakage is small. In the case of a limited thickness, the X-shaped sealing ring can achieve double-layer sealing. Compared with the method of installing two O-rings to achieve double-layer sealing, it saves the internal space of the controller, which is very meaningful for the current situation of the increasing stacking density of internal components.

[0011] The present utility model is further configured such that the chamfering mechanism includes an inlet angle, and the inlet angle is uniformly provided at the hole of the housing. By using the inlet angle, the installation resistance of the sealing ring is reduced. During the assembly process, the housing itself serves as an assembly tool for the sealing ring. While the housing is assembled, the installation of the sealing ring is also completed. One step of the process completes the assembly of two parts, saving production time.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the present utility model provides an installation structure of an electric vehicle controller, which has the following beneficial effects:

[0014] 1. By providing a bearing surface on the power supply post, the sealing ring is placed on the bearing surface. The bearing surface acts as a retaining ring to axially limit the sealing ring, which promotes the installation process of the electric vehicle controller and makes it more convenient and fast to use.

[0015] 2. The structure of the sealing ring is changed from the traditional O-ring to an X-shaped sealing ring with better performance. Compared with the O-ring, the X-shaped sealing ring has a small contact stress and a small installation resistance. Moreover, during the process of buckling the upper cover, the phenomenon of flipping and slipping out of the O-ring will not occur. At the same time, the contact stress distribution of the X-shaped sealing ring is more uniform than that of the O-ring, and the probability of leakage is small. In the case of a limited thickness, the X-shaped sealing ring can achieve double-layer sealing. Compared with the method of installing two O-rings to achieve double-layer sealing, it saves the internal space of the controller, which is very meaningful for the current situation of the increasing stacking density of internal components.

[0016] 3. By providing an inlet angle, the installation resistance of the sealing ring is further reduced. During the assembly process, the housing itself serves as an assembly tool for the sealing ring. While the housing is assembled, the installation of the sealing ring is also completed. One step of the process completes the assembly of two parts, saving production time. Description of the drawings

[0021] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] It should be pointed out that unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0023] In the present utility model, without contrary description, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the convenience of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present utility model.

[0024] Please refer to Figures 1-3 , an installation structure of an electric vehicle controller, including a power supply column 1. There are five power supply columns 1. A sealing ring 2 is detachably connected to the power supply column 1. An outer shell 3 is inserted into the power supply column 1. A chamfering mechanism is provided on the outer shell 3.

[0025] A bearing surface 11 is provided on the power supply column 1.

[0026] The sealing ring 2 is in an X shape.

[0027] In this embodiment, the assembly sequence is to install the sealing ring 2 first and then the outer shell 3. Press the sealing ring 2 onto the bearing surface 11 of the power supply column 1. At this time, since the sealing ring 2 is still in a unidirectional stretching state and the outer diameter is not restricted by the size of the outer shell 3, it is easy to deform, so it only needs a very small force to be pressed in place. And the sealing ring 2 is installed on the power supply column 1 in advance and axially limited by the bearing surface 11 of the power supply column 1, with accurate positioning. Therefore, the sealing ring 2 can be installed in place.

[0028] Please refer to Figure 3 , as an implementation mode of an installation structure of an electric vehicle controller for the chamfering mechanism: The chamfering mechanism includes a lead-in angle 31, and the lead-in angle 31 is uniformly opened at the hole of the outer shell 3.

[0029] More specifically, when the sealing ring 2 is installed on the bearing surface 11 of the power supply post 1, the last step is to assemble the outer shell 3. The guiding angle 31 provided at the hole of the sealing ring 2 of the outer shell 3 further reduces the installation resistance of the sealing ring 2. During the assembly process, the outer shell 3 itself serves as the assembly tooling for the sealing ring 2. While the outer shell 3 is being buckled, it also forms extrusion on the sealing ring 2. The sealing ring 2 has the bearing surface 4 acting as a retaining ring and will not come off. When the outer shell 3 is buckled, the installation of the sealing ring 2 is also completed at the same time. One step of the process completes the assembly of two parts, saving production time. For the installation method of the external sealing ring 2, it is necessary to first install the outer shell 3, and then manually or use tooling to press the five sealing rings 2 into the corresponding holes of the outer shell 3 in sequence. At this time, the outer diameter of the power supply post 1 and the inner diameter of the outer shell 3 have formed internal and external dimensional constraints on the sealing ring 2, making it laborious to press in, and it is difficult to press in place manually, with a long installation time. In comparison, the installation method of the built-in sealing ring 2 is more convenient and efficient.

[0030] In summary, when the overall equipment is in use or operation: the assembly sequence is to first install the sealing ring 2 and then install the outer shell 3. Press the sealing ring 2 onto the bearing surface 11 of the power supply post 1. At this time, since the sealing ring 2 is still in a state of unidirectional tension and its outer diameter is not restricted by the size of the outer shell 3, it is easy to deform, so only a very small force is required to press it in place. Moreover, the sealing ring 2 is installed on the power supply post 1 in advance and is axially limited by the bearing surface 11 of the power supply post 1, with accurate positioning. Therefore, the sealing ring 2 can be installed in place.

[0031] When the sealing ring 2 is installed on the bearing surface 11 of the power supply post 1, the last step is to assemble the outer shell 3. The guiding angle 31 provided at the hole of the sealing ring 2 of the outer shell 3 further reduces the installation resistance of the sealing ring 2. During the assembly process, the outer shell 3 itself serves as the assembly tooling for the sealing ring 2. While the outer shell 3 is being buckled, it also forms extrusion on the sealing ring 2. The sealing ring 2 has the bearing surface 4 acting as a retaining ring and will not come off. When the outer shell 3 is buckled, the installation of the sealing ring 2 is also completed at the same time. One step of the process completes the assembly of two parts, saving production time. For the installation method of the external sealing ring 2, it is necessary to first install the outer shell 3, and then manually or use tooling to press the five sealing rings 2 into the corresponding holes of the outer shell 3 in sequence. At this time, the outer diameter of the power supply post 1 and the inner diameter of the outer shell 3 have formed internal and external dimensional constraints on the sealing ring 2, making it laborious to press in, and it is difficult to press in place manually, with a long installation time. In comparison, the installation method of the built-in sealing ring 2 is more convenient and efficient.

[0032] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
