Example one
Referring to fig. 1a and fig. 1b, fig. 1a is a usage state diagram of an electrical control box according to an embodiment of the present invention, and fig. 1b is an enlarged schematic view of a portion of a structure at a in fig. 1 a.
As shown in fig. 1a and fig. 1b, the electrical control box 100 provided in this embodiment includes a box body assembly 110, the box body assembly 110 includes a box body 111 and a top cover 115, the top cover 115 covers the top surface of the box body 111, an opening 1111 is disposed on a side surface of the box body 111, the electrical control box 100 further includes a cover 120, the cover 120 is connected to the opening 1111, and a receiving cavity is formed between the cover 120 and the box body 111.
Further, the top cover 115 further has a strap 112, and the strap 112 is connected to a circumferential edge of the top cover 115 and is configured to be fastened to the outside of the case body 111 and the cover 120. Thus, the electrical control box 100 can utilize the strap 112 to fasten and limit the components and structures such as the cover 120, so that the components of the electrical control box 100 can be better connected together, and the electrical control box 100 has better sealing performance.
It should be noted that the strap 112 and the top cover 115 may be an integral structure, for example, the strap 112 and the top cover 115 may be formed by integral molding, and here, the connection manner between the strap 112 and the top cover 115 is not particularly limited.
Specifically, the strap 112 surrounds the outer sides of the box body 111 and the cover 120, a gap 113 is formed between the strap 112 and the opening 1111, and a part of the edge structure of the cover 120 is located in the gap 113, so that the part of the edge structure of the cover 120 is inserted into the gap 113.
It should be noted that the electronic control box 100 of the present embodiment may be a sealed electronic control box. Therefore, other foreign matters such as water drops and dust can be prevented from entering the electric control box and damaging electronic elements in the electric control box 100, and the waterproof, dustproof and anticorrosion effects are achieved.
In order to improve the sealing performance inside the electrical control box 100, the electrical control box 100 of the present embodiment further includes an elastic sealing member (not shown), which is located between the edge of the opening 1111 and the cover 120. This enables the cover 120 and the case body 111 to be sealed with an elastic sealing member, thereby engaging with the band 112 to provide a tight coupling between the cover 120 and the case body 111.
Because the box body 111 and the cover 120 are completely hooped and combined by the hoop 112, only one end of the cover 120 extends into the gap 113 to obtain the limit of the hoop 112 before the cover 120 and the box body 111 are assembled in place, and the end of the cover 120 not extending into the gap 113 may incline or tilt relative to the box body 111, thereby affecting the assembly of the whole electronic control box 100. Therefore, after the cover 120 is inserted into the gap 113 formed by the strap 112, the cover 120 and the box body 111 can be pre-positioned and fixed by the pre-positioning structure in the electronic control box 100, so that the cover 120 and the box body 111 can be maintained at the approximately matching assembling position, thereby improving the assembling efficiency and the assembling speed. At least one side wall of the box body 111 is provided with a first pre-positioning structure close to the opening 1111, the cover 120 is provided with a second pre-positioning structure, and the first pre-positioning structure and the second pre-positioning structure form a pre-positioning structure for pre-fixing the cover 120 on the box body 111.
In order to pre-fix the cover 120 and the case body 111 by using the pre-positioning structure, the pre-positioning structure can specifically limit the relative displacement of the cover 120 and the case body 111 in a certain direction, so that the cover 120 and the case body 111 are kept in a subsequent assembly stage, and the cover 120 and the case body 111 can be positioned only by realizing the relative displacement in a single direction. Specifically, the pre-positioning structure limits the relative displacement of the cover 120 and the case body 111 in a first direction, and the cover 120 and the case body 111 are relatively movable in a second direction, wherein the first direction and the second direction are perpendicular to each other, and the cover 120 is inserted between the straps and the side wall of the case body 111 along the second direction. After the pre-positioning of the cover 120 and the box body 111 is completed by the pre-positioning structure, the cover 120 can still be inserted between the strap 112 and the box body 111 until the cover 120 is completely inserted in place. The first direction may be along a z-axis direction in fig. 1a and 3a, the second direction may be along a y-axis direction in fig. 1a and 3a, specifically, the first direction is a width direction of the electronic control box 100 provided in this embodiment in a use state, that is, a thickness direction of the electronic control box 100, the second direction is a height direction of the electronic control box 100 provided in this embodiment in a use state, and an x-axis direction in fig. 1a and 3a is consistent with a length direction of the electronic control box 100 provided in this embodiment in a use state, and in the following description, the first direction and the second direction will not be described again.
Specifically, in order to limit the relative displacement of the cover 120 and the box body 111 in the first direction, as an alternative, the first pre-positioning structure and the second pre-positioning structure may abut against each other in the first direction, so that after pre-fixing, the first pre-positioning structure and the second pre-positioning structure are obstructed by each other in the first direction, and thus cannot move relative to each other. In order to prevent the cover 120 from deforming during the assembly of the electrical control box 100, in this embodiment, at least one corner of the strap 112 corresponding to the edge of the opening 1111 is formed with a protrusion 1121, the edge structure of the opening 1111 is disposed corresponding to the protrusion 1121, and the protrusion 1121 protrudes in a direction away from the side of the opening 1111 to form an accommodating groove 114 for accommodating an elastic sealing member. Specifically, the receiving groove 114 is formed between the protrusion 1121 and the edge of the opening 1111, and a part of the structure of the cover body 120 and a part of the structure of the elastic sealing member are located in the receiving groove 114. In the electrical control box 100 provided in this embodiment, the protruding portions 1121 at two sides of the strap 112 protrude in a direction away from the opening 1111, so as to form the receiving groove 114 for receiving the partial structure of the cover body 120 and the partial structure of the elastic sealing member, so as to improve the sealing performance inside the electrical control box 100, thereby better protecting the internal working circuit of the electrical control box 100, and preventing the cover body 120 from deforming during the installation process. Wherein, optionally, the protruding direction of the protruding portion 1121 is the same as the first length direction of the electrical control box 100. The first longitudinal direction is a direction perpendicular to the height direction of the electrical control box 100, for example, the Z-axis direction in fig. 1a and 3a, and the height direction of the electrical control box 100 is, for example, the y-axis direction in fig. 1a and 3 a.
It will be appreciated that in an alternative embodiment, the strake 112 has two protrusions 1121, and the two protrusions 1121 are respectively located at two corners of opposite side edges of the corresponding opening 1111 of the strake 112.
It should be noted that, in this embodiment, for convenience of molding, the box body 111, the strap 112 and the cover 120, and the box body 111, the strap 112 and the cover 120 may be sheet metal parts, and here, the manufacturing material and the forming process of the box body 111, the strap 112 and the cover 120 are not particularly limited.
In order to facilitate the processing and molding of the protrusion 1121 and make the appearance of the electronic control box 100 more beautiful, in this embodiment, the shape of the protrusion 1121 is limited.
In some alternative embodiments, the protrusion 1121 is an arc-shaped portion, and the arc-shaped portion is understood herein to mean that two end surfaces of the protrusion 1121, which are opposite to each other in the thickness direction of the electrical control box 100, are curved.
In other alternative embodiments, the protrusion 1121 is a step portion connected by bending, where the step portion is understood to be a bending section formed by continuously bending and closer to the arc-shaped section.
In other embodiments, the projection 1121 may have other shapes as long as the recess direction of the projection 1121 is matched with the direction away from the opening, and the shape of the projection 1121 is not particularly limited.
It can be understood that, in general, the shape of the elastic sealing member is adapted to the shape of the side wall at the opening 1111, and therefore, in order to effectively avoid the space for accommodating the elastic sealing member, so as to provide the elastic sealing member, so that the electric control box 100 provided by the present embodiment has better sealing performance, in a specific embodiment of the present embodiment, the protrusion 1121 spans the inner side and the outer side of the opening 1111 along the thickness direction of the side wall of the box body 111. Specifically, a part of the structure of the projection 1121 is located inside the edge of the opening 1111, and another part of the structure of the projection 1121 is located outside the edge of the opening 1111, so that the projection 1121 spans both the inside and the outside of the edge of the opening 1111 in the length direction of the electronic control box 100. In this way, sufficient space for the elastic sealing member can be provided, so that the interior of the electrical control box 100 has better sealing performance.
In order to further limit the structure of the protrusion 1121, so that the interior of the electronic control box 100 has better sealing performance, in the embodiment, the protrusion 1121 protrudes toward a side of the electronic control box 100 away from the opening 1111, and the protruding direction is parallel to the thickness direction of the electronic control box 100. In this way, the projections 1121, and thus the strakes 112, are easily formed.
In a specific implementation manner of this embodiment, the strap 112 includes a pair of protrusions 1121 that are distributed at intervals, and the arrangement direction of the pair of protrusions 1121 is parallel to the length direction of the electronic control box 100, wherein the length direction of the electronic control box 100 is the same as the x-axis direction in fig. 1a and 3a, the opening 1111 has two side edges that are arranged at intervals in the length direction of the electronic control box 100, and the side edges are arranged corresponding to the protrusions 1121, so that the strap 112 spans across the opening 1111 in the length direction of the electronic control box 100.
In order to limit the position between the box body 111 and the cover 120, so that the box body 111 and the cover 120 are reliably connected and high assembly efficiency is achieved, in this embodiment, a pre-positioning structure is disposed between the box body 111 and the cover 120 to limit the relative position between the box body 111 and the cover 120, and the specific structure and various possible implementation forms of the pre-positioning structure in this embodiment will be further described in detail below in combination with the specific structure of the electronic control box 100.

The side wall of the box body 111 may be provided with a first pre-positioning structure, for example, as shown in fig. 2 to fig. 3b, the side of the box body 111 along the length direction thereof has a side wall 1112, a wall surface of the side wall 1112 extends along the thickness direction of the electronic control box 100, and an outer surface of the side wall 1112 is provided with the first pre-positioning structure. Correspondingly, the cover body 120 is formed with a flange 121, and the flange 121 extends along the second direction; the second pre-positioning structure matched with the first pre-positioning structure is arranged on the flanging 121.
Specifically, the first pre-positioning structure is a protrusion 1113 disposed on the outer surface of the sidewall 1112, and the second pre-positioning structure is a catch 1211 formed at the end of the flange 121, and a free end of the catch 1211 extends in the first direction and is configured to abut against a side surface of the protrusion 1113.
Wherein at least one of the protrusion 1113 and the catch 1121 extends in the second direction. In this way, either one of the protrusion 1113 and the catch 1121 constitutes a guide surface extending in the second direction, which can allow the protrusion 1113 and the catch 1121 to move relative to each other in the second direction, and further, the guide surface can be constituted by both the protrusion 1113 and the catch 1121. Illustratively, the protrusion 1113 and the catch 1121 may be relatively moved in this direction by sliding.
Optionally, the protrusion 1113 is a convex hull formed by protruding the sidewall of the box body 111 towards the outside of the electronic control box 100.

Illustratively, two first pre-positioning structures are disposed on two oppositely disposed sidewalls 1112 of the cartridge body 111.
Referring to fig. 4, fig. 4 is an enlarged view of a portion of the structure at D in fig. 1 a. As shown in fig. 4, in order to achieve effective connection between the box body 111 and the cover 120, the electronic control box 100 provided in this embodiment further includes a threaded fastener (not shown), such as a screw, a through hole 122 for the threaded fastener to pass through is formed in a position of the cover 120 close to the bottom 1114, specifically, the through hole 122 penetrates through the cover 120 in a thickness direction of the electronic control box 100, wherein the thickness direction of the electronic control box 100 is a width direction of the electronic control box 100 in a use state, that is, a z-axis direction in fig. 1a and 3a, wherein the threaded fastener can pass through the through hole 122 and extend into the box body 111, and correspondingly, a threaded hole corresponding to the threaded fastener can be formed in the box body 111, so that the threaded fastener passes through the through hole 122 and the threaded hole to perform threaded connection, and the box body 111 and the cover 120 can be detachably connected. In this way, the cover 120 is provided with the through hole 122, so that the box body 111 and the cover 120 can be detachably connected through the threaded fastener, and therefore, the box body 111 and the cover 120 can be limited and fixed by the threaded fastener, and the reliability of connection between the cover 120 and the box body 111 and the internal sealing performance of the electronic control box 100 are further improved.
It should be noted that the axial directions of the through hole 122 and the threaded hole are both along the first direction, i.e., the connection direction of the through hole and the threaded hole matches the installation direction defined by the pre-positioning structure.
In order to facilitate the assembly of the box body 111 and the cover 120, the through hole 122 may be a smooth hole with a smooth inner wall, that is, the inner wall of the through hole 122 is a revolution surface.
Further, in order to assemble the box body 111 and the cover 120 together, during the assembly process, the cover 120 needs to be pulled to move relative to the box body 111 in a direction away from the strap 112 to be in the assembled position, and in order to enable the cover 120 to move relative to the box body 111, in a specific embodiment of the present embodiment, the through hole 122 includes a small-diameter section 123 and a large-diameter section 1222, and the large-diameter section 1222 is communicated with a side wall of the small-diameter section 1221. The arrangement direction of the small-diameter section 1221 and the large-diameter section 1222 is the same as the width direction of the electronic control box 100, the small-diameter section 1221 is located on the side of the large-diameter section 1222 close to the top cover 115 and the strap 112, in addition, the inner wall diameter of the small-diameter section 1221 should be smaller than the inner wall diameter of the large-diameter section 1222, and correspondingly, the nut diameter of the threaded connection is larger than the inner diameter of the small-diameter section 1221 and smaller than the inner diameter of the large-diameter section 1222. Thus, when the cover 120 is moved to move away from the strap 112 relative to the box body 111, the threaded fastener enters the small-diameter section 1221 from the position of the large-diameter section 1222, so that the relative position between the box body 111 and the cover 120 is stabilized.
Specifically, when the cover 120 is mounted on the box body 111, firstly, the cover 120 is inclined at a certain angle relative to the box body 111 to insert a part of the structure of the cover 120 into the gap 113, then, the cover 120 is completely placed on the box body 111, then, the cover 120 is pulled to move relative to the box body 111 in a direction away from the strap 112, at this time, the buckle 1211 is engaged with the protrusion 1113, and then, the threaded fastener is screwed to pass through the small-diameter section 1221 and then connected to the box body 111, it should be noted that the head diameter of the threaded fastener here should be larger than the diameter of the small-diameter section 1221, so as to define the relative positions of the threaded fastener, the box body 111 and the cover 120 in the thickness direction of the electronic control box 100.
