Description

Technical Field

[0001] This utility model belongs to the field of semiconductor packaging technology, and relates to a packaging structure, particularly a tire pressure chip packaging structure. Background Technology

[0002] A tire pressure monitoring chip (TPMS) is a microelectronic device used to monitor and control the air pressure of a car's tires; it is commonly referred to as a tire pressure sensor chip. The TPMS chip is a crucial component of a tire pressure monitoring system (TPMS), responsible for monitoring tire pressure and transmitting the data in real time to the vehicle's electronic control unit (ECU). When tire pressure is abnormal, the system alerts the driver through warning lights or sounds to ensure driving safety.

[0003] Existing tire pressure monitoring chips lose their detection effectiveness after long-term use, mostly due to the internal dry cell battery running out of power. Simply replacing the battery solves the problem. However, in the traditional packaging process, the battery is wrapped with encapsulating glue, making the tire pressure monitoring chip a disposable product that cannot be replaced or disassembled. Therefore, a tire pressure monitoring chip packaging structure is needed to solve the above problem. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a tire pressure monitoring chip packaging structure. The technical problem this utility model aims to solve is that existing tire pressure monitoring chips are disposable products, and the internal battery cannot be replaced or disassembled after the battery is depleted.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A tire pressure monitoring chip packaging structure includes a lower plastic shell, an upper plastic shell mounted on top of the lower plastic shell, a control main board fixedly mounted on the inner wall of the lower plastic shell, a conductive plate fixedly connected to the surface of the control main board, a pair of conductive pins fixedly connected to the surface of the conductive plate, and a protective power supply mechanism provided on the surface of the upper plastic shell.

[0007] The working principle of this utility model is as follows: by setting a pair of conductive pins to contact the surface of the dry cell battery to provide power, by setting a lower plastic shell and an upper plastic shell to protect the internal control board, and by setting a protective power supply mechanism, the lower plastic shell and the upper plastic shell can be separated, which facilitates the replacement of the dry cell battery and extends the service life of the product.

[0008] The protective power supply mechanism includes a battery holder fixedly connected to the surface of the upper plastic shell. A dry cell battery is installed inside the battery holder. The lower surface of the dry cell battery is pressed into contact with the surface of the conductive needle. A snap-on hole is provided on the surface of the battery holder.

[0009] With the above structure, a battery holder is provided for installing dry cell batteries, and a snap-on hole is provided for easy insertion of tools to remove the dry cell batteries from the battery holder.

[0010] A protective plate is fixedly connected to the lower surface of the battery holder. The protective plate is flexible. A pair of through holes are opened on the surface of the protective plate. A pair of plastic sheets are fixedly connected to the inner wall of the through holes. The conductive pin is installed inside the through holes. The plastic sheets are flexible.

[0011] The above structure, by setting a protective plate and installing a plastic sheet, protects the conductive needle and prevents the injected encapsulating glue from affecting the surface of the conductive needle, thus preventing the conductive needle from contacting the surface of the dry cell battery.

[0012] A plastic clip is fixedly connected to the surface of the upper plastic shell, and a buckle is fixedly connected to the surface of the lower plastic shell. The buckle has a slot on its inner wall. A clip head is fixedly connected to the surface of the plastic clip, and the clip head is adapted to the slot. The plastic clip is flexible.

[0013] With the above structure, by setting a clamping head, when the clamping head and the clamping slot are engaged, the clamping stability is maintained by the toughness of the plastic clamping plate.

[0014] A pair of adhesive rings are installed on the inner bottom wall of the lower plastic shell, and the adhesive rings are adhered and fixed to the lower surface of the control motherboard.

[0015] With the above structure, a pair of adhesive rings are provided to facilitate the stable placement of the mainboard inside the lower plastic shell and to facilitate the application of adhesive.

[0016] A sealing strip is fixedly connected to the upper surface of the lower plastic shell, and the lower surface of the upper plastic shell is in contact with the upper surface of the sealing strip. Multiple protrusions are fixedly connected to the surface of the lower plastic shell.

[0017] By adopting the above structure, sealing and waterproofing operations are carried out by setting sealing strips, and multiple protrusions are set to increase the surface contact area between the lower plastic shell and the tire, making the lower plastic shell more stable when installed inside the tire.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] In this invention, the plastic clip is manually engaged to release the clip from the slot. The clip is then pulled out of the clip, and an external tool is inserted into the clip hole to easily remove the dry cell battery from the battery holder for replacement. After reinstalling the upper plastic shell, the conductive pin is inserted into the through hole, causing the surface of the conductive pin to press against the surface of the dry cell battery. The dry cell battery supplies power to the conductive pin. This design facilitates battery replacement and extends the lifespan of the tire pressure monitoring chip. Attached Figure Description

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1-6 As shown, a tire pressure monitoring chip packaging structure includes a lower plastic shell 1, an upper plastic shell 2 mounted on top of the lower plastic shell 1, a control main board 5 fixedly mounted on the inner wall of the lower plastic shell 1, a conductive plate 6 fixedly connected to the surface of the control main board 5, a pair of conductive pins 13 fixedly connected to the surface of the conductive plate 6, and a protective power supply mechanism provided on the surface of the upper plastic shell 2.

[0029] The protective power supply mechanism includes a battery holder 7 fixedly connected to the surface of the upper plastic shell 2. A dry cell battery 12 is installed inside the battery holder 7. The lower surface of the dry cell battery 12 is pressed into contact with the surface of the conductive needle 13. A snap-on hole 17 is provided on the surface of the battery holder 7.

[0030] A protective plate 8 is fixedly connected to the lower surface of the battery holder 7. The protective plate 8 is flexible. A pair of through holes 15 are opened on the surface of the protective plate 8. A pair of plastic sheets 14 are fixedly connected to the inner wall of the through holes 15. The conductive pin 13 is installed inside the through holes 15. The plastic sheets 14 are flexible.

[0031] A plastic card plate 3 is fixedly connected to the surface of the upper plastic shell 2, and a buckle 4 is fixedly connected to the surface of the lower plastic shell 1. A card groove 11 is opened on the inner wall of the buckle 4. A card head 10 is fixedly connected to the surface of the plastic card plate 3. The card head 10 is adapted to the card groove 11. The plastic card plate 3 is flexible.

[0032] A pair of adhesive rings 18 are installed on the inner bottom wall of the lower plastic shell 1, and the adhesive rings 18 are glued and fixed to the lower surface of the control main board 5.

[0033] A sealing strip 9 is fixedly connected to the upper surface of the lower plastic shell 1. The lower surface of the upper plastic shell 2 is in contact with the upper surface of the sealing strip 9. Multiple protrusions 16 are fixedly connected to the surface of the lower plastic shell 1.

[0034] The working principle of this utility model is as follows: When separating the upper plastic shell 2 and the lower plastic shell 1, manually snap the plastic clip 3 to bend and deform it, releasing the inverted state of the clip head 10 and the clip groove 11. Then, pull the plastic clip 3 out of the clip 4, insert an external tool into the clip hole 17, and snap it to remove the dry cell battery 12 installed in the battery holder 7 for replacement. After reinstalling the upper plastic shell 2, insert the conductive pin 13 into the through hole 15 so that the surface of the conductive pin 13 is pressed and contacted with the surface of the dry cell battery 12. The dry cell battery 12 supplies power to the conductive pin 13. The plastic sheet 14 prevents the encapsulating glue from covering the surface of the conductive pin 13 during the glue filling process inside the lower plastic shell 1, which would affect the contact effect between the conductive pin 13 and the dry cell battery 12. The sealing strip 9 is installed to perform a sealing and waterproofing operation. Multiple protrusions 16 increase the surface contact area between the lower plastic shell 1 and the tire, making the lower plastic shell 1 more stable when installed inside the tire.

[0035] In summary, in this utility model, by snapping on the plastic card plate 3, the plastic card plate 3 is deformed, and the upper plastic shell 2 and the lower plastic shell 1 are disassembled and separated. Through the snap-on hole 17, a tool can be inserted to remove the dry cell battery 12 for replacement. The dry cell battery 12 supplies power to the conductive needle 13. With the above structure, the dry cell battery 12 can be easily replaced, and the service life of the tire pressure chip can be extended.
