Description

Technical Field

[0001] This utility model belongs to the technical field of engine starter controller circuit installation, and particularly relates to an engine starter controller circuit assembly structure. Background Technology

[0002] The engine needs to be controlled by a controller, which consists of control circuit components, including circuit boards and a large number of circuit components mounted on the circuit boards, such as capacitors, resistors, power supplies, and control chips.

[0003] Therefore, in order to protect the control circuit components and prevent them from being damaged by external factors such as dust accumulation, the most common method is to seal the circuit components in a housing structure. The housing structure is mostly made of insulating materials such as plastic and rubber, so as to protect the circuit components by utilizing the protective properties of the housing.

[0004] Currently, most sealed protective housings are single-layer structures. However, during controller operation, the circuit components generate a significant amount of heat, causing the housing temperature to rise, especially in high-temperature environments and during frequent engine start-stop cycles. When the circuit is not in operation, the housing temperature returns to room temperature.

[0005] Therefore, the repeated thermal expansion and contraction of the housing makes the housing structure of the protective circuit components prone to deformation. Furthermore, since the housing is mostly made of plastic, it is prone to aging with increased service life. Factors such as vibrations from engine operation also reduce the structural strength and sealing performance of the housing. This leads to a series of drawbacks. For example, reduced sealing performance (due to thermal expansion and contraction deformation) allows dust from the air to enter the housing and adhere to the circuit components, not only hindering heat dissipation but also further exacerbating the heat impact on the housing. The reduced structural strength of the housing makes it more susceptible to deformation under thermal expansion and contraction during actual use, further reducing sealing performance.

[0006] Therefore, traditional, simple housings simply cannot guarantee sufficient structural strength to protect circuit components.

[0007] Meanwhile, traditional sealed protective housings lack heat dissipation structures, preventing the high temperatures generated by the housing and internal components from dissipating quickly. This not only easily damages the circuit structure but also further increases the damage to the protective housing. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an assembly structure for an engine starter controller circuit.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An engine starter controller circuit assembly structure includes an assembly housing structure that seals and assembles the controller circuit elements;

[0011] The assembly housing structure includes an assembly housing for sealing and assembling circuit components;

[0012] The assembly housing includes an outer shell portion and an inner reinforcing rib structure lined on the inner sidewall of the outer shell portion; the inner reinforcing rib structure includes side reinforcing rib portions provided on both sides, and a connecting rib portion is integrally formed between the inner ends of the side reinforcing rib portions.

[0013] The side reinforcing rib plate includes a first curved rib portion adapted to the shape of the outer shell portion, the first curved rib portion integrally formed with a long horizontal rib portion, the long horizontal rib portion integrally formed with a second curved rib portion, the second curved rib portion integrally formed with a short horizontal rib portion, and the short horizontal rib portion integrally formed with a third curved rib portion.

[0014] The connecting stiffener plate is integrally formed on the third curved stiffener on both sides;

[0015] A wiring panel is fitted to the outer side of the assembly housing.

[0016] Preferably, the assembly housing structure further includes a top cover assembled between the top of the socket panel and the top of the assembly housing;

[0017] The top cover is fastened to the assembly housing by a number of bolts.

[0018] Preferably, the outer shell portion has a first bolt connection portion that matches the shape of the first curved rib portion, a second bolt connection portion that matches the shape of the second curved rib portion, and a third bolt connection portion that matches the shape of the third curved rib portion, respectively integrally formed on both sides;

[0019] The first bolt connection part, the second bolt connection part, and the third bolt connection part are respectively provided with threaded connection grooves;

[0020] The bolts are tightened into their respective threaded grooves.

[0021] Preferably, a limit slot is provided on the side wall of the first bolt connection portion;

[0022] The two sides of the plug panel are respectively limited within the limiting slots.

[0023] Preferably, the power strip panel is equipped with a plurality of wiring sockets that mate with the circuit board.

[0024] Preferably, a heat dissipation base plate structure is fixedly connected to the bottom of the assembly housing.

[0025] Preferably, the heat dissipation base plate structure includes a heat dissipation base plate, and the assembly housing and the plug panel are respectively fixedly installed on the heat dissipation base plate;

[0026] The controller circuit components are mounted on the top of the heat sink base plate.

[0027] Preferably, the bottom of the heat dissipation base plate has a plurality of heat dissipation groove structures.

[0028] Preferably, the heat dissipation tank structure includes several long tanks and short tanks.

[0029] Preferably, the heat dissipation base plate includes a top plate portion of an integrally formed assembly shell, and a metal heat dissipation base plate portion is fixedly connected to the bottom of the top plate portion; the heat dissipation groove structure is formed at the bottom of the metal heat dissipation base plate portion.

[0030] This utility model has the following beneficial effects:

[0031] 1. The shell structure comprises an outer shell and an inner reinforcing rib structure lining the inner wall of the outer shell; the height of the inner reinforcing rib structure is slightly higher than the height of the outer shell. Therefore, the inner reinforcing rib structure creates a double-layer shell structure. The deformation of this double-layer shell structure significantly improves structural strength. Furthermore, the inner reinforcing ribs prevent the entire shell structure from deforming excessively due to thermal expansion and contraction. Thus, this method greatly increases the strength of the shell structure.

[0032] 2. The side reinforcing ribs include a first curved rib (S-shaped structure, serving as the starting point of the side reinforcing ribs) adapted to the shape of the outer shell. The first curved rib has an integrally formed long horizontal rib (corresponding to the side length of the outer shell). The long horizontal rib has an integrally formed second curved rib (S-shaped structure). The second curved rib has an integrally formed short horizontal rib. The short horizontal rib has an integrally formed third curved rib (S-shaped structure). The aforementioned connecting ribs are integrally formed on the third curved ribs on both sides (i.e., the side reinforcing ribs on both sides are integrally formed to the connecting ribs via the third curved ribs at their ends, forming the entire inner reinforcing rib structure).

[0033] During operation, the S-shaped first to third curved ribs on the internal reinforcing rib structure effectively neutralize and eliminate stress generated when the shell deforms due to heat. This stress is concentrated on the first to third curved ribs of the S-shaped structure. Therefore, during operation, the shell structure frequently deforms due to thermal expansion and contraction. The design of the first to third curved ribs effectively solves the technical defects of reduced shell stability caused by deformation stress and reduced sealing performance due to irreversible deformation of the shell after prolonged and frequent deformation.

[0034] 3. The assembly housing for the engine starter controller circuit disclosed in this utility model not only has high structural strength and high structural stability, but also maintains minimal deformation after being heated for a long time by the working heat of the circuit components, thus maintaining high sealing performance to protect the circuit components.

[0035] 4. Improve heat dissipation through heat dissipation structure, further protecting circuit components and assembly housing. Attached Figure Description

[0048] Example 1

[0049] like Figure 1-7 As shown, an engine starter controller circuit assembly structure includes an assembly housing structure 2 for sealing and assembling the controller circuit element 1. Specifically, the controller circuit element 1 is a control circuit conventionally used in existing engine starter controllers, and its main structure includes a circuit board 11 and circuit elements mounted on the circuit board 11, including working elements such as capacitors and resistors.

[0050] To provide sealed protection for the controller circuit element 1 and improve the structural strength of the sealing protection device, ensuring high sealing performance even after thermal expansion and contraction during prolonged operation and preventing dust from entering the control circuit, this invention employs a structurally improved assembly housing structure 2 to seal the existing controller circuit element 1. By improving the assembly housing structure 2, its structural strength is increased, thereby enhancing its resistance to deformation, extending its service life, and simultaneously improving its sealing performance.

[0051] Specifically, the assembly housing structure 2 includes an assembly housing 22 for sealing and assembling circuit elements; the assembly housing 22 is made of insulating material, including insulating plastic, etc.

[0052] To improve the structural strength of the assembly housing 22, enhance its resistance to deformation, and improve its sealing performance, the following improvements are made:

[0053] The assembled shell 22 includes an outer shell portion 221 and an inner reinforcing rib structure 222 lined on the inner sidewall of the outer shell portion 221; the height of the inner reinforcing rib structure 222 is slightly higher than the height of the outer shell portion 221. Therefore, the inner reinforcing rib structure 222 forms a double-layer shell structure. The deformation of the double-layer shell structure significantly improves its structural strength. Furthermore, the inner reinforcing ribs prevent the entire shell structure from deforming significantly after thermal expansion and contraction. Thus, the strength of the shell structure is greatly increased. Specifically, the inner reinforcing rib structure 222 includes side reinforcing rib portions 2221, which are integrally formed on the left and right inner sidewalls of the outer shell portion 221. Furthermore, a connecting stiffener 2222 is integrally formed between the inner ends of the side stiffener 2221 (i.e., at the front end); the connecting stiffener 2222 is integrally formed on the front side of the outer shell 221 (the entire outer shell 221 and the inner stiffener structure 222 have a similar U-shaped structure).

[0054] Therefore, the overall structural strength of the outer shell 221 is improved by arranging an integrally formed inner reinforcing rib structure 222 along each side of the outer shell.

[0055] In order to cope with the thermal expansion and contraction process, and to provide a buffer for the deformation caused by thermal expansion and contraction, thereby increasing the service life of the entire shell structure and reducing the deformation range, the shape of the side reinforcing rib plate 2221 is improved. After the structural improvement, when the shell structure is heated by the heat generated by the operation of the circuit components, the stress generated by the deformation of the shell structure is reduced after thermal expansion.

[0056] Specifically, the side reinforcing rib plate portion 2221 includes a first curved rib portion 22211 (with an S-shaped structure, serving as the starting point of the side reinforcing rib plate portion 2221) adapted to the shape of the outer shell portion 221. The first curved rib portion 22211 is integrally formed with a long horizontal rib portion 22212 (corresponding to the side length of the outer shell portion). The long horizontal rib portion 22212 is integrally formed with a second curved rib portion 22213 (with an S-shaped structure). The second curved rib portion 22213 is integrally formed with a short horizontal rib portion 22214. The short horizontal rib portion 22214 is integrally formed with a third curved rib portion 22215 (with an S-shaped structure). The aforementioned connecting stiffener portion 2222 is integrally formed on the third curved stiffener portion 22215 on the left and right sides (i.e., the side reinforcing stiffener portion 2221 on the left and right sides, which is integrally formed to the connecting stiffener portion 2222 through the third curved stiffener portion 22215 at the end position to form the entire inner reinforcing stiffener structure 222).

[0057] During operation, by designing the first to third curved ribs 22211 to 22215 of the S-shaped structure on the internal reinforcing rib plate structure 222, the stress generated by the shell due to thermal deformation is concentrated on the first to third curved ribs 22211 to 22215 of the S-shaped structure. The curved structure of the first to third curved ribs 22211 to 22215 effectively eliminates this stress (using curved structures to release deformation stress is a common application of curved structures in existing technology, such as the rounding of workpiece corners). Therefore, during operation, the shell structure frequently deforms due to thermal expansion and contraction. The structural design of the first to third curved ribs 22211 to 22215 not only effectively solves the technical defects of reduced shell structure stability caused by deformation stress, but also the reduction in sealing performance due to irreversible deformation of the shell after long-term frequent deformation.

[0058] A wiring panel 23 is mounted and connected to the outer side of the aforementioned housing 22. Specifically, similar to the existing circuit protection housing structure, in order to facilitate the connection of data cables and other components to the working circuit board, the wiring panel 23 is equipped with several wiring sockets that mate with the circuit board. Similar to the existing structure, the wiring sockets are connected to the plugs on the data cables, power cables, and other components.

[0059] The aforementioned assembly housing 22 structure 2 also includes a top cover 21 that is assembled and connected between the top of the plug panel 23 and the top of the assembly housing 22. Specifically, the top cover 21 is fastened to the outer shell 221 by bolts.

[0060] Specifically, the outer shell 221 has integrally formed a first bolt connection part A that matches the shape of the first curved rib part 22211, a second bolt connection part B that matches the shape of the second curved rib part 22213, and a third bolt connection part B that matches the shape of the third curved rib part 22215. The first bolt connection part A, the second bolt connection part B, and the third bolt connection part C are respectively provided with threaded connection grooves; the bolts are respectively fastened in the corresponding threaded connection grooves.

[0061] After the top cover 21 is installed, the plug panel 23 is positioned at the bottom of the top cover 21 and the rear end of the outer casing 221.

[0062] like Figure 3 , Figure 5 As shown, in order to increase the stability of the plug panel 23, a limiting slot 2211 is provided on the side wall of the first bolt connection part A (located at the rear end of the outer shell part 221); the left and right sides of the plug panel 23 are respectively limited within the limiting slot 2211.

[0063] Similarly, limit slots 2211 are also provided on both sides of the bottom of the top cover 21 to limit the upper end of the plug panel 23.

[0064] The power strip 23 is fixed to the heat dissipation base plate by bolts. Specifically, a rib plate 231 protruding inward is integrally formed on the inner side wall of the power strip 23. Bolt mounting parts 23111 are integrally formed at both ends of the bottom of the rib plate 231. The mounting bolts are threaded from the heat dissipation base plate upward to the bolt mounting parts to fasten the power strip 23.

[0065] This method facilitates the disassembly of the plug panel 23 and simultaneously increases the sealing of the assembly through the limiting bayonet 2211.

[0066] Example 2

[0067] like Figure 1-7 As shown, in this embodiment, based on the structure of embodiment 1, in order to improve the heat dissipation of the assembly housing 22, firstly to dissipate heat from the circuit components, and secondly to reduce the thermal deformation of the housing after the housing heats up, a heat dissipation base plate structure 3 is fixedly connected to the bottom of the assembly housing 22.

[0068] The heat dissipation base plate structure 3 includes a heat dissipation base plate, which includes a top plate portion 31 of an integrally formed assembly housing 22, and a metal heat dissipation base plate portion 33 is fixedly connected to the bottom of the top plate portion 31.

[0069] The assembly housing 22 and the connector panel 23 are respectively fixedly mounted on the heat dissipation base plate. Specifically, for the connection of the connector panel 23: the mounting bolts are threaded upwards from the heat dissipation base plate to the bolt mounting part 23111. The assembly housing 22 is integrally formed on the top plate part 31.

[0070] Similar to the existing fixed installation method of controller circuit element 1, controller circuit element 1 is installed at the top of the heat sink base plate. Specifically, the circuit board of controller circuit element 1 is fixedly installed on the top plate 31 by means such as support bolts.

[0071] To improve heat dissipation, the bottom of the aforementioned metal heat sink base plate 33 is provided with several heat dissipation groove structures 32. The heat dissipation groove structures 32 form multiple heat dissipation channels to increase the contact surface with air and improve the heat dissipation effect.

[0072] Since the heat sink base plate has through holes for mounting (to facilitate installation such as bolts), the heat sink structure 32 includes several long slots 321 and short slots 322 (the short slots 322 are used to avoid the location of the through holes) in order to avoid the through holes.

[0073] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
