Description

Technical Field

[0001] This utility model relates to the field of fuse box technology, and in particular to a fuse box and a vehicle. Background Technology

[0002] The fuse box is a core safety and power distribution management device in the electrical system of a vehicle (including electric vehicles and gasoline vehicles). It is usually installed in the driver's compartment or engine compartment and is used to integrate and manage the vehicle's power distribution, overcurrent protection, and circuit control functions. Its typical structure includes the fuse box body, the fuse box cover, and the mounting positions inside for installing electrical components such as fuses, relays, and electronic control modules (such as the body control module, BCM). It is electrically connected to the vehicle's power bus via a female connector and supplies power to multiple electrical devices such as the lighting system, air conditioning system, airbags, and ADAS system via a male connector.

[0003] As vehicles become increasingly electronic and intelligent, new models often require more electrical features during replacement or upgrades, such as advanced driver assistance systems (ADAS), power seat memory functions, ambient lighting control systems, and in-vehicle communication modules. These new features increase the overall electrical load on the vehicle, leading to a rise in the number of fuses, relays, and control modules required, making the existing fuse box insufficient for expansion needs.

[0004] In related technologies, to address the aforementioned issues, a common approach is to add expansion modules to the fuse box itself to expand functionality. These expansion modules are used to install new electrical components, thus avoiding the need to redesign the entire fuse box and reducing development costs and time. However, the expansion modules in these technologies are connected only through plug-in connections. During vehicle operation, they are susceptible to dynamic loads such as vibration and impact, or when the fuse box is subjected to collisions during transport. These expansion modules are prone to loosening, displacement, or even detachment. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The technical solutions disclosed in the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 5 This utility model discloses a fuse box, which can be applied to the electrical systems of various vehicles such as electric vehicles and fuel vehicles, serving as a core device for vehicle power distribution, overcurrent protection and circuit control.

[0027] The disclosed fuse box is used to install automotive electrical components. The fuse box can be installed in the driver's compartment or engine compartment, and can contain electrical components such as fuses, relays, and electronic control modules (such as the body control module, BCM).

[0028] The fuse box includes a fuse box body 100, a fuse box bottom cover 200, an expansion module 300, and an anti-detachment structure 400. The fuse box body 100 can be an integrally injection-molded insulating shell, with multiple mounting positions inside for installing electrical components such as fuses, relays, and electronic control modules.

[0029] The lower cover 200 of the fuse box is located below the fuse box body 100 along the first direction, such as when the fuse box is... Figure 1 In the state shown, the first direction can be the vertically upward direction, and the first direction can be... Figure 1 The direction indicated by z. The lower cover 200 of the fuse box can be connected to the fuse box body 100 by means of screws, snap-fit ​​structures, etc. For example, the fuse box body 100 may include a first snap-fit ​​part 130, and the lower cover 200 of the fuse box may include a second snap-fit ​​part 220. The first snap-fit ​​part 130 can snap into the second snap-fit ​​part 220 to connect the lower cover 200 of the fuse box to the fuse box body 100.

[0030] The lower cover 200 of the fuse box is connected to the fuse box body 100 to form an electrical appliance housing space, which is used to house and protect the internal electrical components and prevent dust, moisture and foreign objects from entering.

[0031] The expansion module 300 is located outside the electrical appliance housing space and is installed on the side wall of the fuse box body 100. The expansion module 300 may have additional mounting positions for installing new fuses, relays, or control units to meet electrical expansion needs arising from vehicle upgrades or configuration increases. The expansion module 300 can be installed on the side wall of the fuse box body 100 by plugging, snapping, or bonding; this embodiment does not impose specific limitations on the installation method of the expansion module 300.

[0032] The anti-detachment structure 400 is located on the lower cover 200 of the safe box. The anti-detachment structure 400 is hooked and cooperated with the expansion module 300 to hook the expansion module 300 onto the safe box body 100.

[0033] The fuse box disclosed in this application has an anti-detachment structure 400 on the lower cover 200 of the fuse box. When the expansion module 300 is installed on the side wall of the fuse box body 100, the anti-detachment structure 400 hooks and cooperates with the expansion module 300 to hook the expansion module 300 onto the fuse box body 100. This makes the installation between the expansion module 300 and the fuse box body 100 more stable. In this way, when the vehicle is subjected to dynamic loads such as vibration and impact during driving, or when the fuse box is hit during transportation, the expansion module 300 can be prevented from loosening, displacement, or even falling off.

[0034] Specifically, the anti-detachment structure 400 may include a connecting arm 410. The first end of the connecting arm 410 can be connected to the lower cover 200 of the safety box, and the second end of the connecting arm 410 can extend along a second direction to the underside of the expansion module 300. The second end of the connecting arm 410 may have a hook groove, and the expansion module 300 may have a hook-fitting post. The connecting arm 410 can hook the hook-fitting post through the hook groove to hook the expansion module 300 onto the safety box body 100. The second direction can be as follows: Figure 1 The direction indicated by 'a' is shown.

[0035] In another implementation, please refer to Figure 3 The anti-detachment structure 400 may include a connecting arm 410 and a hook head 420. The first end of the connecting arm 410 may be connected to the lower cover 200 of the safe box. The second end of the connecting arm 410 may extend along a second direction to the bottom of the expansion module 300. The hook head 420 may be located at the second end of the connecting arm 410 and may extend along a first direction. The hook head 420 may also hook and cooperate with the first side wall 310 of the expansion module 300. The first direction is perpendicular to the second direction.

[0036] In the specific assembly process of the fuse box, the expansion module 300 can be installed on the side wall of the fuse box body 100 first, and then the lower cover 200 of the fuse box can be connected to the fuse box body 100. When installing the lower cover 200, the hook-joint portion 420 can be hooked onto the first side wall 310 of the expansion module 300 first, and then the lower cover 200 of the fuse box can be connected to the fuse box body 100. The connecting arm 410 can be an elastic arm with a certain degree of elasticity. When the hook-joint portion 420 and the expansion module 300 are engaged, the connecting arm 410 can undergo elastic deformation so that the hook-joint portion 420 can hook onto the first side wall 310 of the expansion module 300. The safety box disclosed in this application embodiment is configured with an anti-detachment structure 400 including a connecting arm 410 and a hook head 420. The first end of the connecting arm 410 is connected to the lower cover 200 of the safety box, and the second end of the connecting arm 410 extends along the second direction to the lower part of the expansion module 300. The hook head 420 is located at the second end of the connecting arm 410, so that the hook head 420 hooks and engages with the first side wall 310 of the expansion module 300, thereby realizing the hook engagement between the anti-detachment structure 400 and the expansion module 300.

[0037] To improve the stability of the connection between the fuse box body 100 and the fuse box lower cover 200, the connecting arm 410 may optionally have a support boss 411. The support boss 411 may protrude along a first direction and may be lower than the hook head portion 420. The support boss 411 may form a limiting groove 411a with the second side wall 211 of the fuse box lower cover 200. The end face of the first side wall 310 may support and cooperate with the support boss 411. The third side wall 110 of the fuse box body 100 may extend into the limiting groove 411a.

[0038] The safe box disclosed in this application embodiment has a support boss 411 on the connecting arm 410. The support boss 411 protrudes in a first direction and is lower than the hook joint portion 420. The support boss 411 and the second side wall 211 of the safe box lower cover 200 form a limiting groove 411a, so that when the safe box lower cover 200 is installed, the end face of the first side wall 310 of the expansion module 300 can be supported and engaged with the support boss 411, thereby allowing the support boss 411 to be extended. The lower part of module 300 limits the expansion module 300, thereby further improving the connection stability between the expansion module 300 and the fuse box body 100. The third side wall 110 of the fuse box body 100 extends into the limiting groove 411a, which not only plays a positioning role in the connection between the fuse box body 100 and the fuse box lower cover 200, but also improves the connection stability between the fuse box body 100 and the fuse box lower cover 200 under the limiting cooperation of the third side wall 110 and the limiting groove 411a.

[0039] To further improve the stability of the connection between the fuse box body 100 and the fuse box lower cover 200, and to improve the connection stability between the expansion module 300 and the fuse box body 100, the connecting arm 410 may optionally be a plate-shaped structural component. The connecting arm 410 may have supporting bosses 411 on both sides in a third direction. The third direction may be perpendicular to the first direction and perpendicular to the second direction. The third direction may be as follows: Figure 1 The direction indicated by 'b' is shown.

[0040] The safety box disclosed in this application embodiment provides support bosses 411 on both sides of the connecting arm 410 in the third direction, so that the end face of the first side wall 310 of the expansion module 300 can be supported and engaged with the two support bosses 411, thereby further improving the connection stability between the expansion module 300 and the safety box body 100. The third side wall 110 of the safety box body 100 can extend into the two limiting grooves 411a, which can further improve the connection stability between the safety box body 100 and the safety box lower cover 200.

[0041] To improve the strength of the anti-detachment structure 400, the anti-detachment structure 400 may optionally include a reinforcing rib 430, which may be located below the connecting arm 410 and connected between the connecting arm 410 and the second side wall 211 of the safety box lower cover 200.

[0042] The safety box disclosed in this application improves the overall strength of the anti-detachment structure 400 by providing a reinforcing rib 430 below the connecting arm 410 and connecting the connecting arm 410 and the second side wall 211 of the safety box lower cover 200.

[0043] Furthermore, the connecting arm 410 can be a plate-shaped structural component, and the connecting arm 410 can be provided with reinforcing ribs 430 on both sides in the third direction. The third direction can be perpendicular to the first direction and the third direction can be perpendicular to the second direction.

[0044] The safety box disclosed in this application can further improve the overall strength of the anti-detachment structure 400 by providing reinforcing ribs 430 on both sides of the connecting arm 410 in the third direction.

[0045] To further improve the stability of the connection between the expansion module 300 and the fuse box body 100, optionally, there can be multiple anti-detachment structures 400, and the multiple anti-detachment structures 400 can be spaced apart along a third direction, which can be perpendicular to the first direction.

[0046] The safety box disclosed in this application embodiment is provided with multiple anti-detachment structures 400, which are connected and engaged with the expansion module 300 to hook the expansion module 300 onto the safety box body 100, thereby further improving the stability of the connection between the expansion module 300 and the safety box body 100.

[0047] In one optional embodiment, the third sidewall 110 of the fuse box body 100 may be provided with a first plug-in structure 120, and the first sidewall 310 of the expansion module 300 may be provided with a second plug-in structure 320. The expansion module 300 and the fuse box body 100 can be plugged in and engaged along a first direction.

[0048] The fuse box disclosed in this application embodiment has a first insertion structure 120 provided on the third side wall 110 of the fuse box body 100, and a second insertion structure 320 provided on the first side wall 310 of the expansion module 300, so that the expansion module 300 and the fuse box body 100 are inserted and engaged in a first direction. Figure 1 As shown, the expansion module 300 is inserted into the fuse box body 100 from bottom to top, which makes the installation of the fuse box body 100 and the expansion module 300 simpler.

[0049] Specifically, the first plug-in structure 120 can be a plug-in rod extending along the first direction, and the second plug-in structure 320 can be a plug-in hole opened on the first side wall 310 of the expansion module 300. The plug-in rod can be inserted into the plug-in hole, thereby realizing the plug-in cooperation between the expansion module 300 and the fuse box body 100 along the first direction.

[0050] In another embodiment, the first insertion structure 120 may include two first protruding rails 121 extending along a first direction, the two first protruding rails 121 being spaced apart along a third direction, and the two first protruding rails 121 having first slots 121a formed on their opposing inner sidewalls. The second insertion structure 320 may include a first insertion mating part 321, the two opposing ends of which can be correspondingly inserted into the first slots 121a of the two first protruding rails 121.

[0051] The safe box disclosed in this application embodiment is configured by setting the first plug-in structure 120 to include two first protruding rails 121 extending along a first direction, with the two first protruding rails 121 spaced apart along a third direction, and a first slot 121a is provided on the inner sidewall of the two first protruding rails 121, so that the two opposite ends of the first plug-in mating part 321 of the second plug-in structure 320 can be correspondingly inserted into the first slot 121a of the two first protruding rails 121, thereby realizing the plug-in mating of the expansion module 300 and the safe box body 100 along the first direction.

[0052] To further improve the stability of the insertion and engagement between the expansion module 300 and the fuse box body 100, the second insertion structure 320 may optionally include two second protruding rails 322 extending along the first direction, and the two second protruding rails 322 may have second slots 322a formed on their opposing inner sidewalls. The first insertion structure 120 may also include a second insertion mating part 122, and the two opposing ends of the second insertion mating part 122 are correspondingly inserted into the second slots 322a of the two second protruding rails 322.

[0053] The fuse box disclosed in this application, through the insertion and engagement of the first insertion and engagement part 321 and the first slot 121a, and the insertion and engagement of the second insertion and engagement part 122 and the second slot 322a, not only increases the number of insertion and engagement points between the expansion module 300 and the fuse box body 100, but also prevents the expansion module 300 from shaking after being installed on the fuse box body 100 through the two sets of insertion and engagement structures, thereby improving the stability of the insertion and engagement between the expansion module 300 and the fuse box body 100.

[0054] In one optional embodiment, an anti-retraction structure may be provided between the fuse box body 100 and the expansion module 300. The expansion module 300 and the fuse box body 100 are limited by the anti-retraction structure in a direction opposite to the first direction, so as to restrict the expansion module 300 from moving relative to the fuse box body 100 in a direction opposite to the first direction.

[0055] The fuse box disclosed in this application has an anti-retraction structure, which prevents the expansion module 300 from moving relative to the fuse box body 100 in a direction opposite to the first direction after the expansion module 300 is plugged into and installed in place. This makes the connection between the expansion module 300 and the fuse box body 100 tighter and less likely to separate.

[0056] There are many ways to implement the anti-retraction structure. For example, the anti-retraction structure may include an anti-retraction pin, which may be movably disposed on the expansion module 300. The fuse box body 100 may have an anti-retraction insertion hole. After the expansion module 300 and the fuse box body 100 are plugged in and installed in place, the anti-retraction pin may be aligned with the anti-retraction insertion hole, and a portion of the anti-retraction pin may be pushed into the anti-retraction insertion hole, thereby preventing the expansion module 300 from moving relative to the fuse box body 100 in a direction opposite to the first direction.

[0057] In another implementation, please refer to Figure 4 and Figure 5 The anti-retraction structure may include a first elastic arm 510 and an anti-retraction groove 520. The first elastic arm 510 may be provided with a first limiting protrusion 511. One of the first elastic arm 510 and the anti-retraction groove 520 may be provided on the third side wall 110, and the other of the first elastic arm 510 and the anti-retraction groove 520 may be provided on the first side wall 310. The anti-retraction groove 520 may cooperate with the first limiting protrusion 511 for limiting.

[0058] Specifically, during the process of the expansion module 300 and the fuse box body 100 being inserted and engaged in the first direction, the first limiting protrusion 511 can elastically contact the third side wall 110 or the first side wall 310 provided with the anti-retraction groove 520, so that the first elastic arm 510 deforms. The first limiting protrusion 511 moves along the third side wall 110 or the first side wall 310. When the first limiting protrusion 511 moves to the position of the anti-retraction groove 520, under the action of the elastic force of the first elastic arm 510 restoring its elastic deformation, the first limiting protrusion 511 is inserted into the anti-retraction groove 520 and makes limiting contact with the side wall of the anti-retraction groove 520.

[0059] The safe box disclosed in this application has an anti-retraction structure comprising a first elastic arm 510 and an anti-retraction groove 520. The first elastic arm 510 is provided with a first limiting protrusion 511. One of the first elastic arm 510 and the anti-retraction groove 520 is located on the third side wall 110, and the other of the first elastic arm 510 and the anti-retraction groove 520 is located on the first side wall 310. This allows the anti-retraction groove 520 to engage with the first limiting protrusion 511 after the expansion module 300 is inserted into the safe box body 100 along the first direction, thereby preventing the expansion module 300 from moving relative to the safe box body 100 in a direction opposite to the first direction.

[0060] In one optional embodiment, a positioning locking structure may be provided between the fuse box body 100 and the expansion module 300. The positioning locking structure can be used to restrict the expansion module 300 from continuing to move relative to the fuse box body 100 in the first direction after the expansion module 300 is installed in place relative to the fuse box body 100.

[0061] Specifically, the positioning locking structure may include a second elastic arm 610 and a positioning locking groove 620. The second elastic arm 610 may be provided with a second limiting protrusion 611. One of the second elastic arm 610 and the positioning locking groove 620 may be provided on the third side wall 110, and the other may be provided on the first side wall 310. The positioning locking groove 620 may cooperate with the second limiting protrusion 611 for limiting.

[0062] During the insertion and engagement of the expansion module 300 and the fuse box body 100 along the first direction, the second limiting protrusion 611 can slide along the positioning locking groove 620. When the first limiting protrusion 511 moves to the position of the anti-retraction groove 520, the second limiting protrusion 611 can make limiting contact with the side wall of the locking groove 620 to restrict the expansion module 300 from continuing to move relative to the fuse box body 100 along the first direction. Moreover, the second elastic arm 610 can also play a buffering role when the fuse box is impacted, thereby protecting the fuse box.

[0063] Optionally, the locking structure may further include a first positioning step 630 and a second positioning step 640. One of the first positioning step 630 and the second positioning step 640 may be located at the end of the first convex rail 121, and the other of the first positioning step 630 and the second positioning step 640 may be located on the first side wall 310 of the expansion module 300. After the expansion module 300 and the fuse box body 100 are inserted into place along the first direction, the first positioning step 630 and the second positioning step 640 are positioned and engaged to restrict the expansion module 300 from continuing to move along the first direction relative to the fuse box body 100.

[0064] This application also discloses a vehicle, which includes the fuse box disclosed in the above embodiments.

[0065] The vehicle disclosed in this application embodiment, by setting the fuse box disclosed in the above embodiment, enables the anti-detachment structure 400 to hook and cooperate with the expansion module 300 when the expansion module 300 is installed on the side wall of the fuse box body 100, so as to hook the expansion module 300 onto the fuse box body 100.
