[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] Reference below Figure 1-Figure 4 The electronic device 100 according to the embodiment of the present invention is described. For example, the electronic device 100 may be a vehicle-mounted amplifier.

[0042] The electronic device 100 according to the first embodiment of the utility model comprises: a device body 10 and a protective member 20. The device body 10 has a connector 11 for connecting to a device harness 40 on one side along a first direction (eg, direction e1 in the figure), and the first direction intersects the up-down direction.

[0043] Optionally, the device harness 40 and the connector 11 may be detachably connected, for example, the connector 11 has a plug interface oriented in a first direction, and one end of the device harness 40 has a plug terminal that can be inserted into the plug interface.

[0044] Optionally, refer to Figure 1 The device body 10 includes a plurality of connectors 11. For example, the device body 10 includes four connectors 11, and the four connectors 11 are arranged along the second direction (for example, the direction e2 in the figure). The second direction, the first direction, and the up-down direction intersect each other. The four connectors 11 can be connected to four device harnesses 40 respectively.

[0045] For example, refer to Figure 2 The device body 10 includes a housing, a control board 18 and a connector 11. The control board 18 is disposed in the housing. The connector 11 is disposed at one end of the control board 18 along the first direction. A portion of the housing opposite to the connector 11 is formed with an escape opening for escaping the connector 11. The housing may include an upper cover plate 17 and a lower cover plate 19. The control board 18 is located between the upper cover plate 17 and the lower cover plate 19. The upper cover plate 17 and the lower cover plate 19 may be detachably connected, for example, the upper cover plate 17 and the lower cover plate 19 are connected by fasteners 42 such as screws.

[0046] Optionally, refer to Figure 2 A flange 41 is formed at the lower end of the upper cover plate 17, and the flange 41 extends along the circumference of the upper cover plate 17. The inner side edge of the flange 41 abuts against the outer side edge of the lower cover plate 19, so that the fitting point between the upper cover plate 17 and the lower cover plate 19 has a better sealing effect, reducing the entry of external water, dust, etc. into the shell.

[0047] refer to Figure 1 and Figure 2 The protective member 20 has a limiting portion 21, which has an upward limiting effect on the device harness 40. The limiting portion 21 is located on the side of the device body 10 where the connector 11 is provided, and the limiting portion 21 is spaced apart from the connector 11 in the first direction, and the lower surface of the limiting portion 21 is lower than the upper surface of the connector 11. For example, the lower surface of the limiting portion 21 is a first surface 211, and the upper surface of the connector 11 is a second surface 111, and the first surface 211 is lower than the second surface 111. The limiting portion 21 can limit the height of the portion of the device harness 40 connected to the connector 11, for example, the lower surface of the limiting portion 21 can abut against the upper surface of the device harness 40 to prevent the portion of the device harness 40 connected to the connector 11 from moving upward.

[0048] By making the lower surface of the limiting portion 21 of the protective member 20 lower than the upper surface of the connector 11 connected to the device harness 40, the portion of the device harness 40 adjacent to the connector 11 can be limited by the limiting portion 21, so that the portion of the device harness 40 adjacent to the connector 11 is lower than the upper surface of the connector 11 after being limited by the limiting portion 21. In this way, even if there is water on the device harness 40, the water on the device harness 40 will be concentrated at the lower position of the device harness 40 under the action of its own gravity, and the lower position of the device harness 40 is not located at the connection between the device harness 40 and the device body 10 but at the portion of the device harness 40 separated from the device body 10, so as to avoid the position where the device harness 40 is connected to the connector 11 from becoming the lower position of the device harness 40. When there is water on the device harness 40, the water can flow down along the device harness 40 and gather at the lower position of the device harness 40, which can reduce the risk of short circuit failure caused by water flowing into the connector 11 and the device body 10 along the device harness 40, thereby extending the service life of the electronic device 100.

[0049] According to the electronic device 100 of the embodiment of the utility model, the electronic device 100 includes a device body 10 and a protective member 20, and the protective member 20 includes a limiting portion 21 with an upward limiting function for the device wiring harness 40. The limiting portion 21 can limit the upward movement of the portion of the device wiring harness 40 adjacent to the connector 11, and by making the lower surface of the limiting portion 21 lower than the upper surface of the connector 11 connected to the device wiring harness 40, the portion of the device wiring harness 40 adjacent to the connector 11 can be limited by the limiting portion 21 of the protective member 20 to be lower than the upper surface of the connector 11, thereby reducing the risk of short-circuit failure caused by water flowing along the device wiring harness 40 into the connector 11 and the device body 10, thereby extending the service life of the electronic device 100.

[0050] According to some embodiments of the present invention, reference Figure 4 , the lower surface of the limiting portion 21 is higher than the lower surface of the connector 11. By making the lower surface of the limiting portion 21 higher than the lower surface of the connector 11, the entire electronic device 100 can be placed stably, and when the device body 10 is connected to the device harness 40, the device harness 40 has sufficient placement space in the up and down directions, so that the electronic device 100 can also be placed stably when connected to the device harness 40. In addition, while reducing the risk of water flowing into the connector 11 and the device body 10 along the device harness 40 to cause short circuit failure, it can avoid the limiting portion 21 of the protective member 20 from exerting too much downward pressure on the device harness 40, thereby preventing the device harness 40 from being damaged.

[0051] According to some embodiments of the present invention, reference Figure 1 , the spacing between the limiting portion 21 and the connector 11 along the first direction is greater than the size of the connector 11 in the up-down direction. When the electronic device 100 is connected to the device harness 40, the rigidity of the portion of the device harness 40 close to the connector 11 is relatively large. By making the spacing between the limiting portion 21 and the connector 11 along the first direction greater than the size of the connector 11 in the up-down direction, it is possible to avoid the limiting portion 21 from limiting and squeezing the rigid portion of the device harness 40 to cause damage to the connection portion between the device harness 40 and the connector 11, and to make the limiting portion 21 have a large distance from the connector 11, so that the lower position on the device harness 40 is far away from the connector 11, thereby better reducing the risk of water flowing into the connector 11 and the device body 10 along the device harness 40 to cause short circuit failure.

[0052] According to some embodiments of the present invention, reference Figure 1, the spacing between the limiting portion 21 and the connector 11 along the first direction is greater than the size of the connector 11 in the second direction, and the second direction, the first direction, and the up-down direction intersect each other. By making the spacing between the limiting portion 21 and the connector 11 along the first direction greater than the size of the connector 11 in the second direction, it is possible to avoid the limiting portion 21 limiting the rigidity of the device harness 40, and to make the limiting portion 21 have a greater distance from the connector 11, so that the lower position on the device harness 40 is farther from the connector 11, thereby better reducing the risk of water flowing into the connector 11 and the device body 10 along the device harness 40 and causing short circuit failure.

[0053] According to some embodiments of the present invention, reference Figure 3 , the limiting portion 21 extends along the second direction, and the second direction, the first direction, and the up-down direction intersect each other. The limiting portion 21 extends along the second direction, and the device harness 40 can be more fully limited. For example, when the electronic device 100 is connected to a plurality of device harnesses 40, or the width of the device harness 40 in the second direction is large, by extending the limiting portion 21 along the second direction, the device harness 40 can be better limited, and the limiting portion 21 can limit the device harness 40 more fully.

[0054] According to some embodiments of the present invention, reference Figure 1 A routing space 22 for routing the device harness 40 is defined below the protective member 20, and the routing space 22 is located on the side of the device body 10 where the connector 11 is provided. By providing the routing space 22 below the protective member 20, the device harness 40 can have a space for placement below the protective member 20, and by providing the routing space 22 on the side of the device body 10 where the connector 11 is provided, it is convenient for the device harness 40 to be routed along the routing space 22 and connected to the connector 11.

[0055] According to some embodiments of the present invention, reference Figure 1The protective member 20 includes a protective cover plate 23, one end of which is connected to the top of the device body 10 and the other end of which extends in a first direction away from the device body 10. Since the protective cover plate 23 of the protective member 20 is located above the connector 11, it can protect the connector 11 and avoid or reduce the risk of short circuit failure caused by water flowing into the connector 11 and the device body 10 from the top of the device body 10. The wiring space 22 is defined below the protective cover plate 23, and the limiter 21 is connected to the lower side of the protective cover plate 23. In this way, the part of the device harness 40 located in the wiring space 22 can be covered by the protective cover plate 23 in the up and down directions, avoiding or reducing water from falling into or flowing to the part of the device harness 40 located in the wiring space 22, thereby reducing the probability of water on the part of the device harness 40 adjacent to the connector 11, thereby further reducing the risk of short circuit failure caused by water flowing into the connector 11 and the device body 10 along the device harness 40.

[0056] In addition, the protective cover 23 as a whole can also have an upward limiting effect on the portion of the device harness 40 located in the routing space 22. The protective cover 23 can limit the upward movement or motion of the portion of the device harness 40 adjacent to the connector 11, and by extending the other end of the protective cover 23 along the first direction toward a direction away from the device body 10, the protective cover 23 can make the waterproof effect of the device harness 40 more sufficient.

[0057] According to some embodiments of the present invention, reference Figure 1 and Figure 2 , the limiting portion 21 is connected to the other end of the protective cover 23. By arranging the limiting portion 21 at the end of the protective cover 23 away from the device body 10 along the first direction, the limiting portion 21 can be far away from the part where the device harness 40 is connected to the connector 11, so as to avoid the limiting portion 21 limiting and squeezing the part with greater rigidity of the device harness 40 and causing damage to the device harness 40. At the same time, the limiting portion 21 is connected to the end of the protective cover 23 away from the device body 10 along the first direction, and the limiting portion 21 can also be used as the edge of the protective cover 23 in the first direction. Through the contact between the limiting portion 21 and the device harness 40, the water of the device harness 40 is reduced from entering the wiring space 22 along the device harness 40 from the first direction, so that the waterproof effect of the protective member 20 can be more sufficient, thereby further reducing the risk of water flowing into the connector 11 and the device body 10 along the device harness 40 to cause short circuit failure.

[0058] According to some embodiments of the present invention, reference Figure 4, the dimension of the wiring space 22 in the first direction is a, a≥30mm. For example, the value of a can be 30mm, 35mm, 40mm, etc. By making the dimension of the wiring space 22 in the first direction a≥30mm, the wiring space 22 can be made larger, the protective length of the protective element 20 for the device harness 40 can be larger, and the protective element 20 can be more fully waterproof for the connector 11, thereby further reducing the risk of short circuit failure caused by water flowing into the connector 11 and the device body 10 along the device harness 40.

[0059] According to some embodiments of the present invention, reference Figure 2 , a first water retaining rib 24 is provided at the other end of the protective cover 23, and the second direction, the first direction, and the up-down direction intersect each other. Water falling on the protective cover 23 may flow along the protective cover 23 in a direction away from the connector 11, and finally drip onto the device harness 40. By providing the first water retaining rib 24 at the other end of the protective cover 23, the water on the protective cover 23 can be prevented from flowing along the first direction to the other end of the protective cover 23 and dripping downward from the other end of the protective cover 23 onto the device harness 40, so that the waterproof effect of the protective element 20 is better. The first water retaining rib 24 is provided on the upper surface of the protective cover 23 and extends along the second direction, which can better prevent the water on the upper surface of the protective cover 23 from flowing along the first direction to the other end of the protective cover 23 and dripping downward from the other end of the protective cover 23 onto the device harness 40.

[0060] In addition, if there is water on the upper surface of the protective cover 23, the first water retaining rib 24 can also guide the water on the upper surface of the protective cover 23 to flow along the second direction to at least one side of the protective cover 23 along the second direction and drip downward. Since the connector 11 of the device body 10 and the part where the device wiring harness 40 is connected to the connector 11 are both located below the protective cover 23, when the water on the upper surface of the protective cover 23 flows along the second direction to at least one side of the protective cover 23 along the second direction and drips downward, it will not fall on the connector 11 and the part of the device wiring harness 40 connected to the connector 11.

[0061] According to some embodiments of the present invention, reference Figure 1 and Figure 2 The protective member 20 further includes a protective side plate 25, which is disposed on opposite sides of the protective cover plate 23 along the second direction and is located at the lower side of the protective cover plate 23. The second direction, the first direction, and the up-down direction intersect each other. The protective side plate 25 can protect the device harness 40 located below the protective cover plate 23 from the second direction, further improving the protective effect of the protective member 20, for example, reducing the probability of water on the protective cover plate 23 flowing along the second direction to the edge of the protective cover plate 23 and entering the wiring space 22 downward, so that the waterproof effect of the protective member 20 can be more sufficient.

[0062] According to some embodiments of the present invention, reference Figure 1 and Figure 2 The protective side plate 25 extends along the first direction and is connected to the limiting portion 21. By extending the protective side plate 25 along the first direction, it can be ensured that the protective side plate 25 can reduce the probability of water on the protective cover plate 23 flowing along the second direction to the edge of the protective cover plate 23 and entering the wiring space 22 downward, so that the waterproof effect of the protective side plate 25 is more sufficient.

[0063] According to some embodiments of the present invention, reference Figure 2 The lower surface of the protective side plate 25 is higher than the lower surface of the limiting portion 21. Avoid the protective side plate 25 from extending too much to interfere with other structures or affect the arrangement of other structures.

[0064] According to some embodiments of the present invention, reference Figure 1 and Figure 4 , a buffer space 26 is defined between the protective cover plate 23 and the upper surface of the device body 10, and a guide notch 27 connected to the buffer space 26 is formed on the protective side plate 25, and the guide notch 27 is located on at least one side of the buffer space 26 along the second direction. For example, the guide notch 27 can be located on one side of the buffer space 26 along the second direction, and the guide notch 27 can also be located on both sides of the buffer space 26 along the second direction. By defining the buffer space 26 between the protective cover plate 23 and the upper surface of the device body 10, a buffering effect can be played on the water on the upper surface of the device body 10, reducing the water on the upper surface of the device body 10 from flowing around and causing the flow direction and dripping position to be uncontrollable. In addition, the water in the buffer space 26 can be drained by the provided guide notch 27, so that the water in the buffer space 26 flows to the guide notch 27 along the second direction, and flows out from the guide notch 27 to at least one side of the device body 10 along the second direction, reducing the risk of the water on the upper surface of the device body 10 falling down onto the connector 11 and the device harness 40.

[0065] According to some embodiments of the present invention, reference Figure 2, the upper surface of the device body 10 is provided with a second water retaining rib 12. In the first direction, the second water retaining rib 12 is located on the side of the device body 10 close to the wiring space 22, and the protective cover plate 23 is supported on the second water retaining rib 12. The second water retaining rib 12 is provided on the upper surface of the device body 10, which can prevent the water on the upper surface of the device body 10 from flowing along the first direction to the side of the device body 10 close to the connector 11 and flowing downward to the connector 11. In addition, the second water retaining rib 12 can also drain the water, so that the water on the upper surface of the device body 10 flows along the second direction to at least one side of the device body 10 along the second direction and drips downward to at least one side of the device body 10 along the second direction, so that the waterproof effect of the protective member 20 is better. The second water retaining rib 12 is provided on the upper surface of the device body 10 and extends along the second direction, so that the second water retaining rib 12 has a better blocking effect on the flow of water toward the connector 11 and a more sufficient drainage effect on the water along the second direction, and a better waterproof effect on the device harness 40.

[0066] According to some embodiments of the present invention, reference Figure 2 , a supporting rib 28 is provided on the lower side of the protective cover plate 23. In the first direction, the supporting rib 28 is located on the side of the second water retaining rib 12 away from the wiring space 22 and supported on the upper surface of the device body 10. By providing the supporting rib 28 on the lower side of the protective cover plate 23, the protective cover plate 23 can be stably supported on the upper surface of the device body 10, and the supporting rib 28 can also prevent the water on the device body 10 from flowing along the first direction toward other positions of the device body 10. For example, when the above-mentioned cache space 26 is provided between the protective cover plate 23 and the upper surface of the device body 10, the supporting rib 28 can be used as the side wall of the cache space 26, and the supporting rib 28 can prevent the water in the cache space 26 from flowing along the first direction toward the direction away from the second water retaining rib 12 to other positions on the device body 10, and the supporting rib 28 can also guide the water in the cache space 26 to make the water flow along the second direction to at least one side of the device body 10 along the second direction to leave the device body 10.

[0067] According to some embodiments of the present invention, reference Figure 2 and Figure 3The upper surface of the device body 10 is provided with a heat dissipation structure 13, and the heat dissipation structure 13 is located on one side of the protective cover plate 23 along the first direction. For example, the heat dissipation structure 13 may include a plurality of heat sinks, and the plurality of heat sinks may be arranged at intervals along the second direction. The heat dissipation structure 13 may dissipate heat and cool the device body 10 to prevent the internal temperature of the electronic device 100 from being too high. The support rib 28 abuts against the heat dissipation structure 13 in the first direction. By abutting the support rib 28 against the heat dissipation structure 13 in the first direction, the protective cover plate 23 may have a limiting effect in the first direction, and the protective member 20 may be prevented from translating relative to the device body 10 along the first direction, thereby ensuring that the connection between the protective member 20 and the device body 10 is more stable and firm.

[0068] According to some embodiments of the present invention, reference Figure 2 , the protective member 20 is detachably connected to the device body 10. By making the protective member 20 detachably connected to the device body 10, after the protective member 20 is removed, it can be avoided that the protective member 20 affects the connection between the device body 10 and the device harness 40. For example, when connecting the device harness 40 to the connector 11 on the device body 10 or removing the device harness 40 from the device body 10, the protective member 20 can be removed from the device body 10 first, and then the device harness 40 is connected or removed, so as to avoid the protective member 20 affecting the connection or removal operation of the device harness 40, so that the connection or removal operation of the device harness 40 is more convenient. In addition, the structure can be switched according to different waterproof requirements, which is convenient for the modular design of the product.

[0069] According to some embodiments of the present invention, reference Figure 2 , one of the protective member 20 and the device body 10 is provided with a first snap-fitting structure 29, and the other of the protective member 20 and the device body 10 is provided with a second snap-fitting structure 14 snap-fitting with the first snap-fitting structure 29. For example, the protective member 20 is provided with a first snap-fitting structure 29, and the device body 10 is provided with a second snap-fitting structure 14 snap-fitting with the first snap-fitting structure 29. For another example, the device body 10 is provided with a first snap-fitting structure 29, and the protective member 20 is provided with a second snap-fitting structure 14 snap-fitting with the first snap-fitting structure 29. By providing the first snap-fitting structure 29 on one of the protective member 20 and the device body 10 and providing the second snap-fitting structure 14 snap-fitting with the first snap-fitting structure 29 on the other, the disassembly and assembly operation of the protective member 20 and the device body 10 is more convenient.

[0070] According to some embodiments of the present invention, reference Figure 1 and Figure 2The protective member 20 includes a protective cover plate 23, one end of which is detachably connected to the top of the device body 10 and the other end of which extends in a first direction away from the device body 10. The protective cover plate 23 can play a waterproof role for the device harness 40 at the top. By extending the other end of the protective cover plate 23 in the first direction away from the device body 10, the protective cover plate 23 can play a more effective waterproof role for the device harness 40, achieving level 3 waterproof.

[0071] A routing space 22 for routing the device harness 40 is defined below the protective cover 23, and the limiting portion 21 is connected to the lower side of the protective cover 23. By providing the routing space 22 below the protective member 20, the device harness 40 can have a space for placement below the protective member 20. By providing the routing space 22 on the side of the device body 10 where the connector 11 is provided, it is convenient for the device harness 40 to be routed along the routing space 22 and connected to the connector 11. In addition, the protective cover 23 as a whole can also have an upward limiting effect on the portion of the device harness 40 located in the routing space 22, and the protective cover 23 can limit the upward movement or motion of the portion of the device harness 40 adjacent to the connector 11.

[0072] Among them, a first clamping structure 29 is provided at one end of the protective cover plate 23, and a second clamping structure 14 is provided on the device body 10. By providing the first clamping structure 29 at one end of the protective cover plate 23 and providing the second clamping structure 14 on the device body 10, when the protective cover plate 23 is matched with the device body 10, the first clamping structure 29 cooperates with the second clamping structure 14, so that the connection between the protective cover plate 23 and the device body 10 is more stable and can meet the requirement of detachability.

[0073] According to some embodiments of the present invention, reference Figure 2 The first clamping structure 29 includes first clamps 30 provided on two opposite sides of the protective cover plate 23 along the second direction, and the second clamping structure 14 includes second clamps 15 provided on two opposite sides of the device body 10 along the second direction. The two second clamps 15 abut against the two first clamps 30 in the up-down direction respectively, and the second direction, the first direction, and the up-down direction intersect each other. By providing the clamps on the two opposite sides along the second direction, the protective cover plate 23 can be prevented from falling off, resulting in insufficient waterproofing, and the connection between the protective cover plate 23 and the device body 10 can be made more secure.

[0074] According to some embodiments of the present invention, reference Figure 1The side walls of the device body 10 on both sides opposite to each other along the second direction are provided with avoidance grooves 16 for avoiding the first buckle 30, which can prevent the second buckle 15 from protruding from the side wall of the device body 10 along the second direction when cooperating with the first buckle 30, reduce the risk of interference between the second buckle 15 and other structures, and make the overall structure of the electronic device 100 more compact.

[0075] The vehicle according to the second embodiment of the utility model comprises: the electronic device 100 according to the first embodiment of the utility model and a device harness 40 , wherein the device harness 40 is connected to the connector 11 .

[0076] According to the vehicle of the embodiment of the utility model, by setting the electronic device 100 according to the above-mentioned first aspect embodiment of the utility model, the electronic device 100 can reduce the risk of short circuit failure caused by water flowing into the connector 11 and the device body 10 along the device wiring harness 40, thereby extending the service life of the electronic device 100.
