[0041] Example 1
[0042] This embodiment is described using a tray packaging including the cavity structure of the present invention as an example. However, the cavity structure provided by the present invention is not limited to tray packaging and can be used for any packaging that requires a cavity structure to secure a product.
[0043] refer to Figure 1 and Figure 2 As shown, a tray packaging includes a tray, and a cavity structure is provided on the top surface of the tray. The cavity structure includes a fixed cavity 5, and movable limit blocks (a first movable limit block 1, a second movable limit block 2, a third movable limit block 3, and a fourth movable limit block 4) are provided in the fixed cavity 5; the movable limit blocks are used to limit the common local characteristic structures of the products; and a limiting cavity for limiting the outer contours of different products is formed by combining the movable limit blocks.
[0044] By using movable limit blocks to limit the common local characteristic structures of different products, and then installing the movable limit blocks in different installation positions of the fixed cavity 5 according to the sizes of different products, products with different sizes but the same local characteristic structures can be limited; according to the number and type of the common local characteristic structures of the products, corresponding movable limit blocks are selected for combination to form a limiting cavity that limits the outer contours of different products.
[0045] Preferably, the size of the fixed cavity 5 is larger than the upper limit of the size range of the product.
[0046] The length, width and height of the fixed cavity 5 are respectively larger than the upper limit of the length, width and height range of the product. The fixed cavity 5 is universal for the entire series of products and does not require targeted development of the fixed cavity 5.
[0047] Preferably, the fixed cavity 5 is provided with at least two installation positions corresponding to each movable limit block, so as to facilitate adjusting the position of the movable limit block according to the size of the product.
[0048] Preferably, the movable limiting block is detachably connected to the fixed cavity 5, so as to facilitate the reuse of the movable limiting block.
[0049] Preferably, a reinforcing rib is provided on the bottom surface of the tray at a position corresponding to the cavity. The reinforcing rib can enhance the strength of the tray, thereby extending its service life.

[0053] When the top surface of the tray is a groove, the corresponding clamping structure on the bottom surface of the tray is a boss. When the top surface of the tray is a boss, the corresponding clamping structure on the bottom surface of the tray is a groove. When the trays are stacked, the clamping structure can make them stack more flat and stable.
[0054] Example 2
[0055] This embodiment provides a controller package for packaging a controller housing. The controller package includes the tray package of embodiment 1.
[0056] The controller in this embodiment is the PEU (Power Electronic Unit), also known as the power control unit, which is one of the core components of a pure electric vehicle and is responsible for controlling the energy conversion and transmission between the battery pack and the motor. The PEU controller usually includes DC / DC, DC / AC and motor control units.
[0057] This embodiment uses a novel characteristic structure of the power control unit housing to extract four common local characteristic structures by taking the intersection method, and designs corresponding movable positioning blocks, which are as follows:
[0058] refer to Figure 4As shown, a first movable stopper 1 for limiting the first direction has a first step surface 101 for limiting and supporting the first common local characteristic structure. The vertical surface of the first step surface 101 is used for limiting, and the horizontal surface of the first step surface 101 is used for support.
[0059] refer to Figure 8 As shown, the first common local feature structure A1 is a lug structure, located at the edge of the controller housing and extending horizontally. The horizontal surface of the first step surface 101 is used to support the lug structure, and the vertical surface of the first step surface 101 abuts the end surface of the lug structure to limit the position in the x-axis direction.
[0060] Preferably, the first movable stopper 1 has two first step surfaces 101, forming a two-stage step structure. Since the first common local characteristic structure of different products differs in height, by designing a two-stage step structure, only one first movable stopper is required to match different products, reducing the number of movable stopper types.
[0061] The first movable limit block is provided with a first bolt hole 102, and the first movable limit block is fixed in the fixed cavity by means of bolts. The position of the first movable limit block in the first direction is adjusted according to the size of the product in the first direction.
[0062] refer to Figure 5 As shown, a second movable limiting block 2 for limiting the second direction has a second step surface 201 for limiting the second common local characteristic structure.
[0063] The second movable limit block is provided with a second bolt hole 202, and the second movable limit block is fixed in the fixed cavity by bolts. The position of the second movable limit block in the second direction is adjusted according to the size of the product in the second direction.
[0064] refer to Figure 8 As shown, the second common local characteristic structure A2 is a groove structure connected to the edge of the controller housing. The plane of the second step surface 201 of the second movable limit block card 2 supports the bottom of the controller housing, and the vertical surface on the second step surface 201 abuts against the side wall of the groove structure in the x-axis direction to limit it in the y-axis direction.
[0065] refer to Figure 6 As shown, a third movable limit block 3 is used to limit the first direction or the second direction. The third movable limit block 3 has a bevel surface 303, and any one of the two adjacent side surfaces 301 and 302 of the bevel surface 303 is used to limit the third common local characteristic structure of the product in the first direction or the second direction.
[0066] refer to Figure 8 As shown, the third common local characteristic structure A3 is a positive corner structure. The side surface 301 or 302 of the third movable stopper 3 limits the third common local characteristic structure A3. By changing the installation position and installation angle of the third movable stopper 3 within the fixed cavity, different side surfaces of the positive corner structure can be limited. For example, when the third movable stopper 3 is installed in the first installation position, the side surface 301 of the positive corner structure is limited in the x-axis direction. Then, after rotating the third movable stopper 3 90° and installing it in the second installation position, the side surface of the positive corner structure can be limited in the y-axis direction.
[0067] The purpose of providing the beveled surface 303 on the third movable limit block 3 is to avoid interference with the structure adjacent to the third common local feature on the controller housing.
[0068] refer to Figure 7 As shown, the fourth movable limit block 4 is used to limit the first direction and the second direction at the same time. The top surface of the fourth movable limit block 4 is provided with a boss 401 for limiting the fourth common local characteristic structure, and the boss has a positive angle.
[0069] refer to Figure 8 As shown, the fourth common local characteristic structure A4 is a negative angle structure located at the bottom of the controller housing. In this embodiment, it is a right-angled reinforcing rib structure, where two reinforcing ribs are perpendicular to each other and form a right angle. The boss 401 on the fourth movable limit block 4 snaps into the negative angle of the right-angled reinforcing rib structure. The top surface of the boss supports the bottom of the controller housing, and the two side surfaces of the boss on the positive angle respectively abut the two reinforcing ribs, thereby simultaneously limiting the position in the x-axis and y-axis directions.
[0070] Preferably, the fourth movable stopper has a third stepped surface 402 at one end and a recessed angle structure 403 at the other end. The third stepped surface 402 at one end of the fourth movable stopper 4 saves material. The recessed angle structure 403 at the other end of the fourth movable stopper 4 is used to engage with the recessed angle structure of the cavity.
[0071] The above four types of movable limit blocks, combined with the two installation positions of each movable limit block, can be combined into three 4 -1=80 combinations, which can currently adapt to all current controller products and future new products. Those skilled in the art can also design new movable limit blocks as needed for expansion.
[0072] The controller package of this embodiment further includes a tray cover and a tray base. The tray cover is snap-fitted to the top surface of the tray, and the tray base is snap-fitted to the bottom of the tray.
[0073] The tray, tray cover and tray base are all made of injection molding, which can improve the strength compared with the blister molding process. The movable limit block is made of elastic material, such as polyurethane, which can not only protect the product, but also play a role in fine-tuning when limiting the product, avoiding the product from not being able to be smoothly placed in the limit cavity due to dimensional error.
[0074] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of this application.
