DETAILED DESCRIPTION

[0035] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0037] refer to Figures 1 to 8 As shown, this embodiment provides a mounting structure for expanding the capacity of an electrical box, including a connector 1 and at least one mounting seat 2, wherein the mounting seat 2 is used to mount a relay or a fuse.

[0038] One mounting base 2 is usually equipped with one relay or one fuse. When expanding the capacity, the number of relays and fuses to be added is consistent with the number of mounting bases 2 used.

[0039] For details, refer to 1 to Figure 6 As shown, the mounting base 2 is provided with a first connection portion 3, the connecting member 1 is provided with a second connection portion 4, and the connecting member 1 is connected to the mounting base 2 through the cooperation of the first connection portion 3 and the second connection portion 4. The connecting member 1 is provided with a first mounting portion 11, and the first mounting portion 11 is detachably connected to the second mounting portion 101 on the electrical box 100, so that the mounting base 2 with a relay or a fuse installed can be detachably connected to the electrical box 100.

[0040] During specific use, the fuse or relay to be added is installed on the mounting base 2, and then the mounting base 2 with the relay or fuse installed is connected to the connecting piece 1, so that the mounting base 2, the connecting piece 1 and the relay or fuse to be added are combined to form a whole, and then the whole is connected to the second mounting part 101 on the electrical box 100, so that a new fuse or relay is installed on the basis of the original electrical box, thereby expanding the capacity of the original electrical box.

[0041] That is to say, the fuse or relay that needs to be added can be connected to the original electrical box through the electrical box expansion installation structure provided by this embodiment, especially when the capacity of the original electrical box is insufficient, there is no need to redesign a new electrical box, let alone re-open a mold to make a new electrical box, which saves the design cycle and development cycle, and is more convenient for expansion. At the same time, it also saves the cost required for expansion to a certain extent.

[0042] At the same time, compared with the solution in the prior art that a new electrical box must be redesigned, a new mold must be made to produce a new electrical box, and the capacity can only be expanded once, the electrical box expansion installation structure of this embodiment can achieve multiple expansions of the electrical box 100, which has better applicability and is more in line with the development trend of intelligent vehicles.

[0043] Since the first mounting portion 11 and the second mounting portion 101 are detachably connected, that is, the connector 1 and the electrical box 100 are detachably connected, and since the mounting base 2 is connected to the connector 1 through the cooperation of the first connecting portion 3 and the second connecting portion 4, the mounting base 2 and the electrical box 100 can be detachably connected, so that if the relay or fuse needs to be replaced or repaired, the relay or fuse that needs to be replaced or repaired can be removed from the electrical box 100, which is convenient for replacement or repair. At the same time, it helps to extend the service life of the electrical box 100.

[0044] It should be noted that before expansion, the second mounting portion 101 needs to be provided on the electrical box 100. During expansion, there is no order of connection between the connector 1 and the electrical box 100, the connector 1 and the mounting base 2, and the mounting base 2 and the fuse or relay.

[0045] The mounting structure for expanding the capacity of the electrical box provided in this embodiment is provided with a connector 1 and at least one mounting seat 2, wherein the mounting seat 2 is used to install a relay or a fuse. A first connecting portion 3 is provided on the mounting seat 2, and a second connecting portion 4 is provided on the connector 1, so that the connector 1 and the mounting seat 2 can be connected together through the cooperation of the first connecting portion 3 and the second connecting portion 4. A first mounting portion 11 is provided on the connector 1, and the first mounting portion 11 can be detachably connected to the second mounting portion 101 on the electrical box 100, so that the mounting seat 2 can be detachably connected to the electrical box 100. In this way, as new functions are added, new fuses or relays need to be configured on the electrical box 100. When the capacity of the electrical box 100 is insufficient, the fuses or relays to be added are installed on the mounting seat 2, and the mounting seat 2 is connected to the connector 1 through the cooperation of the first connecting portion 3 and the second connecting portion 4, and then the first mounting portion 11 of the connector 1 is connected to the second mounting portion 101 on the electrical box 100, and the new fuses or relays to be added can be installed on the original electrical box 100, thereby expanding the capacity of the original electrical box. Compared with the solution in the prior art that requires redesigning a new electrical box and then re-molding and making a new electrical box, the time required for expansion is saved and the convenience of expansion is improved. At the same time, the cost required for expansion is saved to a certain extent.

[0046] In other embodiments, the mounting base 2 and the connecting member 1 may be integrally formed by injection molding, for example, with good integrity and high structural strength.

[0047] In some embodiments, reference Figure 1 , Figure 7 and Figure 8 As shown, the first mounting portion 11 is a mounting protrusion, and the second mounting portion 101 is a mounting hole for the mounting protrusion to extend into. The mounting protrusion is snap-fitted with the mounting hole, and the structure is simple, easy to manufacture, and convenient to install and disassemble, and easy to replace.

[0048] In a specific implementation, at least part of the mounting protrusion is elastic, which facilitates the quick connection of the connector 1 to the electrical box 100, thereby further improving the convenience of installation and removal between the connector 1 and the electrical box 100 and the stability of the connection, making capacity expansion more convenient.

[0049] The mounting boss may be made of plastic.

[0050] In some embodiments, reference Figures 2 to 6 As shown, the first connection part 3 is a slot, and the second connection part 4 is a plug-in protrusion inserted in the slot. The plug-in protrusion and the slot are detachably plugged in, and the connection is convenient and stable, which is convenient for expanding the capacity of the electrical box.

[0051] At the same time, if one of the mounting base 2 and the connecting member 1 is damaged, they only need to be disassembled and separated, and the damaged mounting base 2 or connecting member 1 can be replaced, which saves the cost of expansion to a certain extent.

[0052] In a specific implementation, the slot and the insertion protrusion can be inserted and connected together in a sliding manner, for example, which is convenient for connection.

[0053] Among them, the sliding fit direction between the slot and the insertion protrusion, for example, can intersect with the plug-in direction between the mounting protrusion and the mounting hole, so that the overall structure formed by the mounting seat 2, the connector 1 and the relay or fuse, as well as its connection stability on the electrical box are higher.

[0054] In some implementations, reference Figure 6 As shown, one end of the slot in the length direction is blocked to form a blocked end of the slot; the other end of the slot in the length direction is open to form an open end of the slot.

[0055] In some embodiments, reference Figure 2 , Figure 3 and Figure 5 As shown, the plug-in protrusion includes a main body 41 and plug-in wings 42. The main body 41 is connected to the connector 1, and the plug-in wings 42 are arranged on the side wall of the main body 41. Figure 4 and Figure 6 As shown, the slot includes a clamping slot 31 for the main body 41 to extend into and a connecting slot 32 for the plug-in wing 42 to extend into. It has a simple structure, is convenient to connect, and is easy to expand.

[0056] During specific use, the main body 41 is inserted into the clamping groove 31 from one side, and at the same time, the plug-in wing 42 is also inserted into the connecting groove 32. Then, the connector 1 or the mounting seat 2 is held and moved along the extension direction of the slot until the main body 41 and the clamping groove 31 are plugged into place, and the plug-in wing 42 and the connecting groove 32 are plugged into place, so that the connector 1 and the mounting seat 2 can be connected together.

[0057] The extending directions of the clamping groove 31 and the connecting groove 32 are consistent and perpendicular to the length direction of the mounting protrusion.

[0058] In some embodiments, reference Figure 2 , Figure 3 and Figure 5 As shown, there are two plug-in wings 42 , both of which are located on the side of the main body 41 away from the connector 1 and are disposed on two opposite side walls of the main body 41 . There are two connecting grooves 32 , and one connecting groove 32 corresponds to one plug-in wing 42 .

[0059] That is to say, a plug-in wing 42 is respectively provided on both sides of the main body 41, and correspondingly, a connecting groove 32 is respectively provided on the two groove walls of the clamping groove 31. One plug-in wing 42 corresponds to one connecting groove 32, which increases the combination area between the plug protrusion and the slot, thereby further improving the connection strength between the connector 1 and the mounting base 2, and further improving the stability of the expanded fuse and relay on the electrical box 100.

[0060] In some embodiments, reference Figure 4 and Figure 6 As shown, two mounting walls 6 are provided on the mounting seat 2, and the two mounting walls 6 are arranged opposite to each other and at intervals, and a clamping groove 31 is defined between the two mounting walls 6. The connecting groove 32 is opened on the side of the mounting wall 6 facing the clamping groove 31. Such an arrangement makes the clamping groove 31 protrude and exposed on the outside of the mounting seat 2, so as to facilitate the connection between the mounting seat 2 and the connecting member 1.

[0061] In some embodiments, reference Figure 7 As shown, there are at least two mounting seats 2, and a second connection portion 4 is provided on a side of each mounting seat 2 that is away from the corresponding first connection portion 3. Two adjacent mounting seats 2 are detachably connected through the first connection portion 3 of one mounting seat 2 and the second connection portion 4 of the other mounting seat 2, and the connector 1 is connected to the mounting seat 2 near the electrical box 100.

[0062] That is to say, the installation structure for expanding the capacity of the electrical box of this embodiment may include multiple mounting seats 2, and a slot is provided on one side of each mounting seat 2, and a protrusion is provided on the other side of each mounting seat 2, that is, the slot and protrusion on each mounting seat 2 are respectively arranged on the opposite side walls of the mounting seat 2.

[0063] During specific use, multiple mounting seats 2 can be stacked, and two adjacent mounting seats 2 are connected together through the slot of one of the mounting seats 2 and the plug protrusion of the other mounting seat 2, and the connecting member 1 is connected to the mounting seat 2 closest to the electrical box 100. In this way, multiple mounting seats 2 can be connected to the electrical box 100 at the same time through one connecting member 1.

[0064] Among them, each mounting base 2 is connected to a relay or a fuse, so that multiple relays, or multiple fuses, or mixedly arranged relays and fuses can be connected to the electrical box 100, saving space and achieving a better expansion effect.

[0065] In some implementations, reference Figure 5As shown, on each mounting seat 2, a stop wall 51 is provided on one side of the two plug-in wings 42. The two stop walls 51 can be connected to the sides of the two plug-in wings 42 facing away from the main body 41, and extend outward in directions away from each other. In this way, when the mounting seat 2 and the connecting member 1 are connected in place, the opening end of the corresponding slot abuts against the two stop walls 51, further improving the connection stability between the mounting seat 2 and the connecting member 1.

[0066] In specific implementation, two avoidance grooves 52 for accommodating the stop wall 51 are provided at the notch of the clamping groove 31. The two avoidance grooves 52 are located on the same side as the opening end of the slot, and one avoidance groove 52 corresponds to one stop wall 51. In this way, when the mounting seat 2 and the connecting member 1 are connected in place, the corresponding stop wall 51 abuts against the groove wall of the corresponding avoidance groove 52, which has a better limiting effect.

[0067] In some other implementations, reference Figure 2 As shown, the stop wall 51 can also be arranged on the end surface of the plug-in wing 42 and extend downward.

[0068] In some embodiments, reference Figures 1 to 6 As shown, a first limiting structure 7 is provided on the connecting member 1, and a second limiting structure 8 is provided on the mounting seat 2. The first limiting structure 7 and the second limiting structure 8 are connected in cooperation to limit the relative displacement of the mounting seat 2 and the connecting member 1 when the first connecting portion 3 and the second connecting portion 4 are connected, so that the connection stability between the connecting member 1 and the mounting seat 2 is better, thereby improving the stability of the relay or fuse on the electrical box 100.

[0069] In some embodiments, reference Figures 1 to 6 As shown, the first limiting structure 7 includes a first limiting protrusion arranged on the second connecting part 4, and the second limiting structure 8 includes a second limiting protrusion arranged on the first connecting part 3. When the first connecting part 3 and the second connecting part 4 are connected, the first limiting protrusion and the second limiting protrusion abut against each other. The structure is simple, easy to manufacture, and has a good limiting effect.

[0070] In a specific implementation, along the sliding plug-in direction between the connector 1 and the mounting seat 2, the second limiting protrusion on the mounting seat 2 stops on the back side of the first limiting protrusion on the connector 1, thereby preventing the two from sliding relative to each other in the opposite direction when they are installed in place.

[0071] In some embodiments, reference Figure 1 and Figure 2As shown, a stop flange 9 is provided on the circumferential outer side of the connector 1, and the stop flange 9 is located between the first mounting portion 11 and the second connecting portion 4. The diameter of the stop flange 9 is larger than the diameter of the mounting hole. When the plug-in protrusion on the connector 1 is snapped into place with the mounting hole on the electrical box 100, the stop flange 9 stops on the outer wall of the electrical box 100, increasing the contact area between the connector 1 and the electrical box 100, thereby improving the connection stability between the two, and further improving the stability of the expanded relay or fuse on the electrical box.

[0072] This embodiment also provides an electrical appliance box assembly, which includes a mounting structure for expanding the capacity of the electrical appliance box.
