Description

Technical Field

[0001] This utility model relates to the field of automotive control technology, specifically to an installation structure for a passenger vehicle BCM controller. Background Technology

[0002] The Body Control Panel (BCM), also known as the vehicle's computer, is an electronic control unit used in automotive engineering to control the vehicle's electrical systems. It is a crucial component of a car. Common functions of the BCM include controlling power windows, power mirrors, air conditioning, headlights, turn signals, anti-theft locking systems, central locking, and defrosting devices. The BCM can connect to other onboard ECUs via a bus. A key function of the BCM is to simplify operation and reduce manual intervention by passengers, thus minimizing distraction. The automotive body control system encompasses vehicle safety, comfort controls, and information communication systems, primarily designed to enhance the vehicle's safety, comfort, and convenience.

[0003] Chinese Utility Model Patent Publication No. CN212628728U discloses a novel automotive BCM controller. The specification of this new BCM controller reveals that the use of a lower housing, upper housing, support column, control board, mounting block, and sleeve facilitates assembly; the use of a first dustproof plate and a second dustproof plate provides dust protection; and the use of vents, vent pipes, and a fan provides heat dissipation. These features make the new automotive BCM controller more convenient to use. However, this new BCM controller lacks a multi-installation structure between the bottom housing and the top cover, which can hinder quick installation. Furthermore, vibrations during vehicle operation can cause the connection structure to loosen, affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an installation structure for a passenger vehicle BCM controller. It can effectively solve the problems in the prior art where there is no design for various installation structures between the bottom shell and the top cover, which easily leads to difficulties in quick installation between the bottom shell and the top cover, and the connection structure may loosen due to vibration generated during vehicle operation, thus affecting normal use.

[0005] The technical solution adopted by this utility model is: an installation structure for a passenger vehicle BCM controller, including a bottom shell and a top cover. A circuit board is disposed inside the bottom shell. A bracket is fixedly installed at the end of the bottom shell away from the top cover. A groove 1 and a groove 2 are formed along the inner edge of the bottom shell. The diameter of groove 1 is larger than the diameter of groove 2. A reinforcing rib and a positioning seat are fixedly installed at the end of the inner edge of the bottom shell near the bottom. A slot is formed along the inner edge of the positioning seat. A protrusion 1 and a protrusion 2 are fixedly installed at the end of the top cover near the bottom shell. A connection port is provided at the end of the top cover away from the bottom shell. A second bracket is fixedly installed at the outer edge of the top cover. The protrusion 1 and the protrusion 2 correspond to the groove 1 and the groove 2.

[0006] Preferably, a plug is fixedly installed at one end of the top cover near the bottom shell, and the plug and the slot are plugged in.

[0007] Through the above technical solution, by using the cooperation of the insert and the slot, during installation, the insert can quickly align the protrusion one and protrusion two with the groove one and groove two, avoiding the top cover from shifting and causing damage to the circuit board due to pressure, and can achieve rapid positioning of the top cover and the bottom shell.

[0008] Preferably, a connecting lug 1 is fixedly installed on the outer edge of the bottom shell, and a connecting groove 1 is formed through the end of the connecting lug 1 away from the bottom shell. A connecting lug 2 is fixedly installed on the outer edge of the top cover, and a connecting groove 2 is formed through the end of the connecting lug 2 away from the top cover. The connecting lug 1 and the connecting lug 2 correspond one-to-one. A bolt is provided through the end of the connecting lug 2 away from the connecting lug 1. The bolt passes through the connecting groove 1 and the connecting groove 2. A nut is threadedly connected to the outer edge of the bolt.

[0009] With the above technical solution, after the plug is inserted into the slot, the first connecting ear and the second connecting ear are locked with bolts and nuts to form a detachable rigid connection. This ensures that the top cover and the bottom shell fit tightly to prevent dust and moisture from entering the internal circuit board. It also allows the shell to be quickly opened by loosening the bolts during maintenance, which reduces the difficulty of assembly.

[0010] Preferably, there are two identical sets of connecting ear one, connecting groove one, connecting groove two, and connecting ear two in each set, and the connecting ear one, connecting groove one, connecting groove two, and connecting ear two in each set are symmetrically distributed about the center line of the bottom shell.

[0011] Through the above technical solution, the symmetrically distributed connecting ear assembly can balance the locking force between the top cover and the bottom shell, avoid shell deformation due to unilateral force, and effectively disperse impact force in the vehicle driving vibration environment, prevent bolt loosening, and ensure the sealing and structural stability of the BCM controller.

[0012] Preferably, a first card block is fixed at the end of the card holder away from the bottom shell. The first card block is an elastic card block. A card groove is opened at the end of the second card block away from the top cover. The end of the first card block near the top cover adopts an inclined design.

[0013] Through the above technical solution, the inclined end face design of the elastic block one can automatically slide into the slot when the top cover is pressed down, and generate clamping force through elastic deformation to achieve quick installation. The initial locking of the top cover and the bottom shell can be completed without additional tools. When used with bolts, it can enhance the overall sealing performance. When disassembling, simply press the block one to deform it and disengage it from the slot to quickly separate the shell, which greatly improves the installation efficiency.

[0014] Preferably, the end of the top cover away from the bottom shell has a sound-permeable hole, and the end of the top cover near the bottom shell has a dustproof net.

[0015] Through the above technical solution, the sound-permeable hole can ensure that the sound of the buzzer or speaker inside the BCM controller can be transmitted normally, meeting the functional requirements of vehicle alarm prompts, etc. The dustproof mesh covering the inside of the sound-permeable hole can block dust, debris and other impurities from entering the housing, and prevent the circuit board from short circuit or failure due to dust accumulation.

[0016] Preferably, a positioning block is fixedly installed at the end of the bottom shell away from the top cover, and a positioning groove is formed at the end of the positioning block away from the bottom shell.

[0017] The above technical solution, through the design of positioning blocks and positioning slots, can assist in the precise docking of the BCM controller and the vehicle mounting bracket. During installation, the positioning block is inserted into the corresponding slot of the bracket, which can quickly determine the installation position of the controller and avoid loose connections or misaligned interfaces caused by manual alignment errors.

[0018] Compared with the prior art, this utility model provides an installation structure for a passenger vehicle BCM controller, which has the following advantages:

[0019] 1. The passenger vehicle BCM controller uses an installation structure where, after the pin is inserted into the slot, connecting ear one and connecting ear two are locked together with bolts and nuts to form a detachable rigid connection. This ensures that the top cover and bottom shell fit tightly together, preventing dust and moisture from entering the internal circuit board. It also allows for quick opening of the shell during maintenance by loosening the bolts, reducing assembly difficulty. The symmetrically distributed connecting ear assembly balances the locking force between the top cover and bottom shell, preventing shell deformation due to unilateral force. In the vibration environment of vehicle driving, the symmetrical structure can effectively disperse impact force and prevent bolts from loosening.

[0020] 2. The mounting structure of this passenger vehicle BCM controller uses a combination of pins and slots. During installation, the pins can be inserted into the slots to quickly align protrusions one and two with grooves one and two, preventing the circuit board from being damaged due to pressure caused by the top cover shifting. This allows for quick positioning of the top cover and bottom shell. The inclined end face design of the elastic locking block one allows it to automatically slide into the slot when the top cover is pressed down, generating a locking force through elastic deformation, achieving quick installation. Initial locking of the top cover and bottom shell can be completed without additional tools. When used with bolts, it can enhance the overall sealing performance. During disassembly, simply press the locking block one to deform it and disengage it from the slot to quickly separate the housing, greatly improving installation efficiency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides an installation structure for a BCM controller in a passenger vehicle, including a bottom shell 1 and a top cover 14. A circuit board 13 is disposed inside the bottom shell 1. A card holder 6 is fixedly installed at the end of the bottom shell 1 away from the top cover 14. A groove 8 and a groove 9 are formed along the inner edge of the bottom shell 1. The diameter of groove 8 is larger than the diameter of groove 9. A reinforcing rib 10 and a positioning seat 11 are fixedly installed at the end of the inner edge of the bottom shell 1 near the bottom. A slot 12 is formed along the inner edge of the positioning seat 11. A protrusion 15 and a protrusion 16 are fixedly installed at the end of the top cover 14 near the bottom shell 1. A connection port 22 is provided at the end of the top cover 14 away from the bottom shell 1. A card block 23 is fixedly installed at the outer edge of the top cover 14. The protrusion 15 and the protrusion 16 correspond to the groove 8 and the groove 9.

[0031] Specifically, a pin 17 is fixedly installed at one end of the top cover 14 near the bottom shell 1. The pin 17 and the slot 12 are plugged in. The advantage is that, through the cooperation of the pin 17 and the slot 12, during installation, the pin 17 can be inserted into the slot 12 to quickly align the protrusion 15, protrusion 16 and groove 8 and groove 9, avoiding the top cover from shifting and causing the circuit board 13 to be damaged by pressure. This can achieve quick positioning of the top cover 14 and the bottom shell 1.

[0032] Specifically, a connecting ear 1 4 is fixedly installed on the outer edge of the bottom shell 1. A connecting groove 1 5 is opened through the end of the connecting ear 1 4 away from the bottom shell 1. A connecting ear 2 18 is fixedly installed on the outer edge of the top cover 14. A connecting groove 2 19 is opened through the end of the connecting ear 2 18 away from the top cover 14. The connecting ear 1 4 and the connecting ear 2 18 correspond one-to-one. A bolt 20 is provided through the end of the connecting ear 2 18 away from the connecting ear 1 4. The bolt 20 passes through the connecting groove 1 5 and the connecting groove 2 19. A nut 21 is threadedly connected to the outer edge of the bolt 20. The advantage is that after the insert 17 is inserted into the slot 12, the connecting ear 1 4 and the connecting ear 2 18 are locked by the bolt 20 and the nut 21 to form a detachable rigid connection. This can ensure that the top cover 14 and the bottom shell 1 fit tightly to prevent dust and moisture from entering the internal circuit board 13. It can also quickly open the shell by loosening the bolt during maintenance, which can reduce the assembly difficulty.

[0033] Specifically, there are two identical sets of connecting ear 1 4, connecting slot 1 5, connecting slot 2 19, and connecting ear 2 18. Each set of connecting ear 1 4, connecting slot 1 5, connecting slot 2 19, and connecting ear 2 18 has two identical sets. Each set of connecting ear 1 4, connecting slot 1 5, connecting slot 2 19, and connecting ear 2 18 is symmetrically distributed about the center line of the bottom shell 1. The advantage is that the symmetrically distributed connecting ear assembly can balance the locking force between the top cover 14 and the bottom shell 1, avoiding shell deformation due to unilateral force. In the vibration environment of vehicle driving, the symmetrical structure can effectively disperse the impact force, prevent the bolt 20 from loosening, and ensure the sealing and structural stability of the BCM controller.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, a locking block 7 is fixed at the end of the card holder 6 away from the bottom shell 1. The locking block 7 is an elastic locking block 7. A slot 24 is opened at the end of the locking block 23 away from the top cover 14. The end of the locking block 7 near the top cover 14 adopts an inclined design. The advantage is that the inclined end face design of the elastic locking block 7 can automatically slide into the slot 24 when the top cover 14 is pressed down. The locking force is generated by elastic deformation, which can achieve quick installation. The initial locking of the top cover and the bottom shell can be completed without additional tools. When used with bolts 20, it can enhance the overall sealing. When disassembling, simply press the locking block 7 to deform it and disengage it from the slot 24 to quickly separate the shell, which greatly improves the installation efficiency.

[0036] Specifically, a sound-permeable hole 26 is provided through the end of the top cover 14 away from the bottom shell 1, and a dustproof mesh 25 is provided at the end of the top cover 14 near the bottom shell 1. The advantage is that the sound-permeable hole 26 can ensure that the sound of the buzzer or speaker inside the BCM controller can be transmitted normally, meeting the functional requirements of vehicle alarm prompts, etc. The dustproof mesh 25 covers the inside of the sound-permeable hole, which can block dust, debris and other impurities from entering the housing, and prevent the circuit board 13 from short-circuiting or malfunctioning due to dust accumulation.

[0037] Specifically, a positioning block 2 is fixedly installed at the end of the bottom shell 1 away from the top cover 14. A positioning groove 3 is opened at the end of the positioning block 2 away from the bottom shell 1. The advantage is that the design of the positioning block 2 and the positioning groove 3 can assist in the precise docking of the BCM controller with the vehicle mounting bracket. During installation, the positioning block 2 is inserted into the corresponding groove of the bracket, which can quickly determine the installation position of the controller and avoid loose connection or misalignment of interface due to manual alignment error.

[0038] Working Principle: During use, the insertion post 17 and slot 12 work together. During installation, the insertion post 17 quickly aligns with protrusions 15 and 16 and grooves 8 and 9, preventing the top cover from shifting and causing damage to the circuit board 13. This allows for rapid positioning of the top cover 14 and bottom shell 1. After the insertion post 17 is inserted into the slot 12, connecting ears 4 and 18 are locked together with bolts 20 and nuts 21, forming a detachable rigid connection. This ensures a tight fit between the top cover 14 and bottom shell 1, preventing dust and moisture from entering the internal circuit board 13. It also allows for quick opening of the shell during maintenance by loosening the bolts, reducing assembly difficulty. The symmetrically distributed connecting ear assembly balances the locking force between the top cover 14 and bottom shell 1, preventing deformation due to unilateral force. In vehicle vibration environments, the symmetrical structure effectively disperses impact forces, preventing bolts 20 from loosening and ensuring the BCM (Body Module) remains stable. The controller's sealing and structural stability are enhanced by the inclined end face design of the elastic locking block 7, which automatically slides into the slot 24 when the top cover 14 is pressed down. The elastic deformation generates a locking force, enabling rapid installation without additional tools. The initial locking of the top cover and bottom shell is achieved without additional tools. When used with bolts 20, it enhances overall sealing. For disassembly, simply press the locking block 7 to deform it and disengage it from the slot 24, allowing for quick separation of the housing and significantly improving installation efficiency. The sound-permeable hole 26 ensures normal sound transmission from the buzzer or speaker inside the BCM controller, meeting the functional requirements of vehicle alarm prompts. The dustproof mesh 25 covers the inside of the sound-permeable hole, preventing dust, debris, and other impurities from entering the housing and avoiding short circuits or malfunctions in the circuit board 13 due to dust accumulation. The design of the positioning block 2 and positioning slot 3 assists in the precise docking of the BCM controller with the vehicle mounting bracket. During installation, the positioning block 2 is inserted into the corresponding slot of the bracket, quickly determining the controller's installation position and avoiding loose connections or misaligned interfaces caused by manual alignment errors.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
