Detailed Implementation

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "left," and "right" generally refer to the orientation defined in the corresponding figures, while "inner" and "outer" may refer to the inner and outer contours of the corresponding component or its location within or outside its surrounding environment, depending on the specific context. Furthermore, when the following description relates to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not imply sequentiality or importance.

[0032] In existing technologies, the water tap connector is designed separately and can be welded to the power module heat sink, and then the power module heat sink is welded to the motor controller housing, which is cumbersome and complicated to assemble; the low-voltage connector and the high-voltage connector are close in space, which affects the EMC (Electromagnetic Compatibility) performance; the parts have low modal characteristics and poor NVH performance; the low-voltage connector has no physical protection and poor salt spray resistance.

[0033] In another related embodiment, the high-voltage connector, low-voltage connector, and water nozzle interface are arranged on different surfaces of the motor controller housing. This makes the housing difficult to process, the motor controller assembly complex, and the airtightness test fixture design complex. A separate motor controller cover needs to be designed, but the cover has poor rigidity, poor NVH performance, and a non-compact structure. The water nozzle interfaces are oriented in opposite directions, making it difficult to arrange the motor controller on the vehicle and prone to salt spray accumulation. The separate capacitor housing requires heat to be transferred to the electronic control housing through a thermally conductive interface material, resulting in poor heat dissipation performance and short capacitor life.

[0034] To address the various problems existing in the above-mentioned related embodiments, such as Figures 1 to 5 As shown, this disclosure provides a housing 1 for a motor controller, the housing 1 having an opening 10 for mounting a connector 2, wherein a retaining wall 11 for protecting the connector 2 is provided on the housing 1 at the outer periphery of the opening 10.

[0035] It should be noted that the retaining wall 11 can be integrally die-cast with the shell 1. The shape of the opening 10 is not limited and can be designed according to the shape of the connector 2 to be installed. A whole ring of retaining wall 11 can be set around the outer perimeter of the opening 10. One, two or more retaining walls 11 can also be set as needed. All of these are within the protection scope of this disclosure. The height and shape of the retaining wall 11 can be designed as needed. This disclosure does not impose any specific restrictions.

[0036] In the housing 1 of the motor controller provided in this disclosure, a retaining wall 11 is added to the outer periphery of the connector 2. The connector 2 is located in the internal space enclosed by the retaining wall 11, which can provide sealing protection for the connector 2 and improve its salt spray resistance. Furthermore, the retaining wall 11 and the housing 1 can be an integral structure, which can improve the overall rigidity of the motor controller housing 1, thereby improving NVH performance.

[0037] In this disclosure, such as Figure 1 and Figure 4 As shown, the housing 1 has a first opening 101 for installing a low-voltage connector 21 and a second opening 102 for installing a high-voltage connector 22. A retaining wall 11 is provided around the outer periphery of the first opening 101 and / or the second opening 102. This disclosure includes embodiments where a retaining wall 11 is provided around the outer periphery of the low-voltage connector 21, embodiments where a retaining wall 11 is provided around the outer periphery of the high-voltage connector 22, and embodiments where retaining walls 11 are provided around both. All of these fall within the scope of this disclosure. The figures use the low-voltage connector 21 with a retaining wall 11 as an example to illustrate the structure of the retaining wall 11 in detail.

[0038] The retaining wall 11 can be any suitable structure. For example... Figure 1 As shown, the housing 1 has a cavity 12 for accommodating a capacitor, and a portion of the cavity wall of the cavity 12 can be constructed as a baffle 11. The baffle 11 is formed using the existing structure on the housing 1 without additional processing. In embodiments where the cavity 12 has a cuboid structure, any one of the cavity walls can be constructed as a baffle 11, depending on the location of the low-voltage connector 21.

[0039] For example, such as Figure 1 As shown, the first opening 101 is located on one side of the cavity 12 along its length, i.e., as... Figure 3 As shown, the low-voltage connector 21 can be installed on the left side of the cavity 12, and the first cavity wall 121 of the cavity 12 (the left cavity wall in the figure) can be formed as a baffle 11, such as... Figure 4 As shown, the baffle wall 11 also includes a side baffle wall 111, one end of which is connected to the first cavity wall 121, and the other end extends to the edge of the housing 1. In this embodiment, two baffle walls 11 are provided, one being the first cavity wall 121 of the cavity 12, and the other being the side baffle wall 111. The height of the side baffle wall 111 can be the same as or different from the height of the first cavity wall 121. The height of the two baffle walls 11 can be between 10-15 mm, and can be designed according to specific needs.

[0040] In this disclosure, such as Figure 4As shown, an outer perimeter baffle 112 is provided on the side of the first opening 101 opposite to the first cavity wall 121 and / or on the side opposite to the side baffle 111. The height of the outer perimeter baffle 112 is lower than that of the first cavity wall 121. The slightly lower height of the outer perimeter baffle 112 facilitates the installation of the low-voltage connector 21 and the insertion and removal of the low-voltage connector 21 from external connectors, while also providing protection. This disclosure includes embodiments in which the outer perimeter baffle 112 is provided only on the side opposite to the first cavity wall 121, embodiments in which the outer perimeter baffle 112 is provided only on the side opposite to the side baffle 111, and embodiments in which the outer perimeter baffle 112 is provided on both the side opposite to the first side wall 121 and the side opposite to the side baffle 111.

[0041] For example, the housing 1 is provided with cooling channels and reinforcing ribs 13 connected to the cooling channels. The side where the opening of the cavity 12 is located can be the inner surface of the housing 1, and the side opposite to the inner surface is the outer surface. The cooling channels can be located on... Figure 4 The inner surface of the area shown in the dashed box, and the outer surface of the housing 1 at the position shown in the dashed box, are provided with reinforcing ribs 13. The reinforcing ribs 13 are provided on the housing 1 and connected to the cooling channels. The reinforcing ribs 13 can improve the overall rigidity of the housing 1 while dissipating heat from the cavity 12 that houses the capacitor. Similarly, the reinforcing ribs 13 can also be integrally die-cast with the housing 1.

[0042] There are several ways to design the reinforcing rib 13. For example, such as... Figure 4 and Figure 5 As shown, the housing 1 is provided with multiple first reinforcing ribs 131. One end of the multiple first reinforcing ribs 131 is connected to the second cavity wall 122 of the cavity 12, and the other end extends toward the edge of the housing 1. The multiple first reinforcing ribs 131 are arranged at intervals along the direction of the second cavity wall 122. The first reinforcing ribs 131 near the first opening 101 can be formed as a baffle wall 11. The first cavity wall 121 and the second cavity wall 122 are arranged adjacent to each other. In this embodiment, at least three baffles 11 are designed: one is the first cavity wall 121 of the cavity 12, one is the side baffle 111, and the other is a first reinforcing rib 131. The first reinforcing rib 131 forming the baffle 11 can be arranged parallel to the side baffle 111. In this embodiment, in order to avoid the outer baffle 112, one end of the first reinforcing rib 131 and the side baffle 111 is connected to the first cavity wall 121, and the other end forms a funnel-shaped opening. The outer baffle 112 is placed in the space between the first reinforcing rib 131 and the side baffle 111, which can play a better protective role.

[0043] For example, as shown in the figure, the height of the side wall 111 gradually decreases along the direction close to the edge of the housing 1 to form a slope. The gradual decrease in the height of the side wall 111 can avoid surrounding components while ensuring the protective effect, prevent interference with the installation of other components, and avoid the edge of the housing 1 from protruding too much.

[0044] For example, the height of the multiple first reinforcing ribs 131 gradually decreases along the direction close to the edge of the housing 1. The edge of the housing 1 is provided with multiple housing mounting holes 100. Along the direction toward the housing mounting holes 100, the height of the multiple first reinforcing ribs 131 gradually decreases. Under the premise of strengthening the bottom surface of the cooling channel and assisting the heat dissipation of the capacitor cavity, the design of the housing 1 is minimized and lightweight.

[0045] In this disclosure, such as Figure 5 As shown, a second reinforcing rib 132 is provided between two adjacent first reinforcing ribs 131 on the shell 1. There can be multiple second reinforcing ribs 132 or just one, and multiple second reinforcing ribs 132 can be arranged parallel to the second cavity wall 122. The number, arrangement, and shape of the second reinforcing ribs 132 are not limited, and can further improve the rigidity and heat dissipation effect at the location of the cooling channel.

[0046] Furthermore, in this disclosure, such as Figure 4 As shown, the housing 1 is provided with at least one of the following: a water nozzle interface 14, an external interface 120, a first opening 101 for installing a low-voltage connector 21, a second opening 102 for installing a high-voltage connector 22, and a third opening 103 for installing a vent valve 3. The water nozzle interface 14, the external interface 120, the first opening 101, the second opening 102, and the third opening 103 are located on the same surface of the housing 1. The water nozzle interface 14 is used to introduce cooling medium into the cooling channel to cool the components inside the housing 1. The external interface 120 can be located on the cavity 12 that houses the capacitor, such as... Figure 1 As shown, there are two external interfaces 120. Since the external interfaces 120 need to be precision machined, the external interfaces 120, water nozzle interface 14, low-pressure connector 21, high-pressure connector 22, vent valve 3 and other components that need to be operated are all located on the same side of the housing 1. This can reduce the need to change fixtures during the machining process and facilitate the design and operation of the airtightness test plug tool when the motor controller performs an airtightness test.

[0047] The faucet interface 14 is a non-independent part; it can be an integral structure with the housing 1. It can be die-cast integrally with the housing 1, and the faucet interface 14 can be machined from the die-cast blank, reducing the number of parts, improving the overall integrity of the housing 1, and simplifying the design of the faucet interface 14, eliminating the need for traditional riveting or adhesive joints. In other embodiments, at least one of the external interface 120, the first opening 101, the second opening 102, and the third opening 103 can also be an integral structure with the housing 1, further enhancing overall integrity.

[0048] The axis of the faucet interface 14 is perpendicular to the surface mentioned above, which facilitates its arrangement and installation. The faucet interface 14 can be used for... Figure 1 The threaded connector shown can also be Figure 6 The quick-connect type shown is not limited in this disclosure.

[0049] In this disclosure, the housing 1 has a three-phase interface for mounting a three-phase copper busbar 4, a first opening 101 for mounting a low-voltage connector 21, and a second opening 102 for mounting a high-voltage connector 22, wherein, as Figure 3 As shown, the three-phase interface can be close to the first edge 1001 of the housing 1, the first opening 101 and the second opening 102 are close to the second edge 1002 of the housing 1, and the first opening 101 and the second opening 102 are respectively located at both ends of the second edge 1002, and the first edge 1001 and the second edge 1002 are arranged opposite to each other.

[0050] In this embodiment, the outer shape of the housing 1 can be roughly designed as a cuboid structure. The first edge 1001 and the second edge 1002 can be two long sides arranged opposite each other. In this embodiment, the high-voltage connector 22 can protrude from its location, and the interior can be used to install the filter component 5 described below. This also increases the distance between the high-voltage connector 22 and the three-phase copper busbar 4 and the low-voltage connector 21, keeping the low-voltage connector 21, high-voltage connector 22, and three-phase copper busbar 4 as far apart as possible. The three-phase copper busbar 4 is arranged in... Figure 3 At the top, the low-voltage connector 21 is arranged at the far left, and the high-voltage connector 22 is arranged at the bottom and to the right. This arrangement effectively reduces interference between high and low voltage, and between high-voltage AC and DC, and improves EMC performance.

[0051] According to a second aspect of this disclosure, a motor controller is provided, which includes the housing 1 of the motor controller described above, and the motor controller has all the beneficial effects of the housing 1 described above, which will not be repeated here.

[0052] The motor controller includes components such as a low-voltage connector 21, a high-voltage connector 22, and a vent valve 3, which are installed on the outer surface of the housing 1. The inner surface of the housing 1 is provided with a capacitor, a circuit board 6, a three-phase copper busbar 4, and a filter assembly 5 located near the high-voltage connector 22. The above components can be installed in corresponding openings or interfaces to achieve component fixation and installation.

[0053] According to a third aspect of this disclosure, a vehicle is provided that includes the motor controller provided in this disclosure. The vehicle has all the beneficial effects of the described motor controller and its housing, which will not be repeated here.

Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.
