[0002] The purpose of a collision power module (CPM) is to ensure the reliable operation of the door unlocking system after a car collision, thereby improving the efficiency of passenger rescue and their chances of survival.

[0003] The assembly steps for traditional collision power modules mainly include the following: Secure the PCBA board to the top cover using M3 copper studs, then spray polyurethane, and finally fit the base to the top cover, securing them diagonally with screws.

[0004] However, due to limitations of some vehicle models, it is not possible to fix the base and the top cover together by installing diagonal screws. This means that installing diagonal screws will cause interference, thus preventing the collision power module from being installed on the car. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a collision power supply module, which aims to change the fixing method between the housing and the bottom cover of the collision power supply, thereby making the collision power supply meet the usage requirements of vehicle models.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A collision power module for use as an emergency unlocking power supply in automobiles, comprising, A housing having an internal housing chamber that extends along the housing's own extension direction and opens to the lower surface of the housing; A PCBA board with a battery enters the housing cavity through an opening on the lower surface of the housing along the vertical direction and is then fixed. The bottom cover has a hanging lug on its upper surface, and the three adjacent side walls of the housing have hanging posts that extend horizontally. When the hanging lug is on the hanging post, the bottom cover is fixed to the lower surface of the housing.

[0007] Preferably, the collision power module further includes a protrusion formed on the upper surface of the housing, and the protrusion having a protrusion chamber that extends along the protrusion's own extension direction until it opens to the lower surface of the protrusion and communicates with the housing chamber. The battery is arranged vertically, and the battery enters the protruding cavity through the housing cavity.

[0008] Preferably, the housing has a long side and a wide side, and the number of hanging posts is multiple, with some distributed on one of the wide sides of the housing and others evenly distributed on the two long sides of the housing.

[0009] Preferably, a hanging column groove is provided on the side wall of the housing, which extends along the vertical direction of the housing, and one end of the hanging column is fixed in the hanging column groove, while the other end extends along the horizontal direction.

[0010] Furthermore, the hanging column groove extends upward in an open manner along the vertical direction.

[0011] Preferably, the contact area between the bottom cover and the housing is further coated with sealant to seal and fix the contact area between the bottom cover and the housing.

[0012] Preferably, the number of fixing ears is three, with two parallel fixing ears provided on one wide side of the housing, and one fixing ear and a plug-in interface provided on the other wide side.

[0013] Preferably, a label is fixedly mounted on the upper surface of the housing.

[0014] Preferably, the lower surface of the housing has a through hole, and a breathable membrane is installed on the through hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. Because the bottom cover of this utility model has a hanging ear on its upper surface, and the three adjacent side walls of the housing have hanging posts that extend horizontally; when the hanging ear is on the hanging post, the bottom cover is fixed to the lower surface of the housing. Thus, according to the requirements of the vehicle model, the hanging ear on the bottom cover of the collision power module can be hung on the hanging post of the housing. Compared with the method of diagonally inserting screws, this avoids the situation where the bottom cover cannot be installed on the housing due to the requirements of the vehicle interior space.

[0016] 2. In this utility model, the hanging groove extends vertically upward in an open manner. The purpose is that after the bottom cover covers the open part of the lower surface of the shell, the hanging ear moves downward through the open hanging groove until the hanging hole on the hanging ear is hooked onto the hanging post, so that the bottom cover covers the open part of the lower surface of the shell. Then, sealant is applied to the contact area between the bottom cover and the shell. That is, after the bottom cover covers the open part of the lower surface of the shell, the sealant is used to seal and fix the contact area between the bottom cover and the shell, so that it has good waterproof, dustproof and other protective performance.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0019] like Figure 1-6 As shown, a collision power module is used for automotive emergency unlocking power, comprising, The housing 1 has a housing chamber inside, and the housing chamber extends along the extension direction of the housing 1 and opens to the lower surface of the housing 1; A protrusion 2 is formed on the upper surface of the housing 1, and the protrusion 2 has a protrusion cavity that extends along the extension direction of the protrusion 2 until it opens to the lower surface of the protrusion 2 and communicates with the housing cavity. PCBA board 3 enters the housing cavity through the opening on the lower surface of housing 1 in a vertical direction and is fixed therein (PCBA board 3 is installed in the housing cavity by screws); PCBA board 3 has battery 4, which extends in a vertical direction and enters the protruding cavity through the housing cavity at the connection between the protruding cavity and the housing cavity; A bottom cover 5 is fixed vertically to the lower surface of the housing 1 to seal the opening on the lower surface of the housing 1; the upper surface of the bottom cover 5 has a hanging ear 51, and the side wall of the housing 1 has a hanging post 101 extending horizontally; when the hanging ear 51 covers the hanging post 101, the bottom cover 5 is fixed to the lower surface of the housing 1; a hanging post groove 102 is provided on the side wall of the housing 1, extending vertically along the housing 1, one end of the hanging post 101 is fixed in the hanging post groove 102, and the other end extends horizontally; furthermore, as... Figure 2 , 3As shown, the hanging groove 102 extends upward in an open manner in the vertical direction; the purpose is that after the bottom cover 5 covers the open part of the lower surface of the housing 1, the hanging ear 51 moves downward through the open hanging groove 102 until the hanging hole on the hanging ear 51 is hooked on the hanging post 101, so as to achieve the bottom cover covering the open part of the lower surface of the housing 1. like Figure 6 As shown, sealant 6 is applied to the contact area between the bottom cover 5 and the housing 1. Then, after the bottom cover 5 covers the open area on the lower surface of the housing, the sealant 6 is used to seal and fix the contact area between the bottom cover 5 and the housing 1, so that it has good waterproof and dustproof protective performance. Alternatively, sealant 6 can be applied before the bottom cover 5 covers the open area on the lower surface of the housing 1, and then the sealant 6 can be applied to the contact area after the bottom cover 5 covers the housing 1. A label 7 is fixedly installed on the upper surface of the housing 1 (the label 7 is fixed by a method disclosed in the prior art, such as adhesive), which can provide relevant information for the impact power module, such as rated power, rated current, rated voltage, manufacturing date, etc. The lower surface of the housing 1 has a through hole 11, and a breathable membrane 8 is installed on the through hole. The purpose is to protect the air pressure balance inside and outside the power module, ensure the integrity of the seal, prevent stress on the housing 1, extend its service life, prevent water and dust from entering from the external environment, and prevent water vapor condensation inside the housing.

[0020] The housing 1 has a long side and a wide side, and a fixing lug 9 is provided on the wide side of the housing for mounting the collision power module on a vehicle; specifically: as follows: Figure 1 As shown, the top cross-section of the housing 1 is rectangular, and there are three fixing ears 9. Two fixing ears 9 are located on the wide side of one end of the housing 1, and the other fixing ear 9 is located on the wide side of the other end of the housing 1 (more specifically, on the edge of the wide side and close to one of the long sides). A pluggable interface 10 is also formed on the wide side. The pluggable interface 10 (which is electrically connected to the PCBA board - not shown in the figure) is close to the edge of the other long side.
