[0002] Aging refers to the condition of temperature and humidity exceeding the general use environment, so that the equipment used under such conditions can reach the state that can only be achieved under the temperature and humidity of the general use environment for a long time in a short time. It can detect the stability and service life of the equipment for a long time. Since the failure of electronic products often occurs in the early and late stages of product use, the high-temperature load aging of the product can allow the product to enter a stable working state as soon as possible. High-temperature load aging mainly simulates the harsh use environment and actual use conditions, so that a certain current passes through the original electronic components under a high temperature environment, so that the hidden failures of electronic products can be exposed at the beginning of use, potential faults and defects of the product can be eliminated, and the amplifier with stable functions can be selected. Load aging is one of the reliability processes in the production of car amplifiers. Since the batch of car amplifiers need to be aged in a high-temperature aging room, the ambient temperature is 60℃, and personnel need to enter the aging room to operate. The temperature in the aging room is high, and it is difficult for personnel to operate; in addition, there are many types of car amplifiers, poor versatility, and high tooling prices.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The technical solutions of the present invention are described in many aspects below in conjunction with the drawings and embodiments.

[0021] For the convenience of description below, the terms “left”, “right”, “up”, “down”, etc. mentioned below are consistent with the left, right, up, down, etc. directions of the drawings themselves.

[0022] like Figure 1-5 As shown, the present disclosure provides a burn-in vehicle for a vehicle-mounted power amplifier, wherein the vehicle-mounted power amplifier is a variety of vehicle-mounted power amplifier devices, vehicle-mounted power amplifiers, etc., and the vehicle-mounted power amplifier can be installed in vehicles such as cars and trucks. The burn-in vehicle includes components such as a multi-layer frame, a burn-in box, and a line speed assembly 103. An burn-in box is installed on each layer of the multi-layer frame, and an burn-in box cover 102 is installed on the upper part of the burn-in box. Multiple vehicle-mounted power amplifiers are placed on the burn-in box cover 102. A current connector 206, a total current meter 204, an overload protection circuit breaker switch 205, a first connector, and a second connector are arranged on the side of the burn-in box.

[0023] A plurality of vehicle-mounted power amplifier connection components are arranged on the side of the aging box, and the vehicle-mounted power amplifier connection components include: a third connector for signal transmission, a first aviation plug 211 and an ammeter 212 for power transmission; the third connector is respectively connected with the first connector and the second connector; the first connector is used to distribute the external input signal to each third connector, and each third connector outputs the data to an external computer through the second connector; during the aging process, the working status of the vehicle-mounted power amplifier can be detected by an external computer, and after the aging is completed, the external computer can automatically determine whether each power amplifier is qualified, saving manpower and material resources.

[0024] The line speed assembly 103 includes: a dedicated plug-in for a vehicle amplifier 301, a fourth connector, and a second aviation plug 303; the dedicated plug-in for a vehicle amplifier 301 is connected to the vehicle amplifier, the fourth connector is connected to the third connector; and the second aviation plug 303 is connected to the first aviation plug 211. The first connector and the second connector can be a variety of connectors, such as a heavy-duty connector.

[0025] In some embodiments, Figure 3 As shown, the line speed assembly consists of a dedicated plug-in 301 for a vehicle-mounted power amplifier, a heavy-duty connector 302 for signal transmission, an aviation plug 303 for power transmission, and the like.

[0026] like Figure 1 As shown, the aging car is divided into a four-layer structure, which can carry and age 56 vehicle-mounted amplifiers 101 at the same time. The aging car includes a multi-layer frame of aluminum profiles, an aging box, and a line speed component 103. When performing the vehicle-mounted amplifier aging operation, first place the vehicle-mounted amplifier 101 on the aging box cover 102 outside the aging room, quickly plug and connect the line speed component 103 with the vehicle-mounted amplifier 101, and plug and connect the line speed component 103 with the aging car through the heavy-duty connector 104 and the aviation plug 105.

[0027] The power supply of the aging room and the aging car are quickly connected through the single-core high-current connector 106, and the power supply device is turned on to supply power to the aging car. Through the connected A2B signal or the CAN signal sent by the computer, the signal can be transmitted to the heavy-duty connector 107 of the aging car body through the shielded line, which is used to be allocated to the interface corresponding to each vehicle-mounted power amplifier, that is, the connector. Turn on the computer to control the CAN signal analyzer and the data analysis and storage device, and transmit it to the heavy-duty connector 109 of the aging car body through the shielded line to be allocated to the interface corresponding to each vehicle-mounted power amplifier, so that the vehicle-mounted power amplifier data can be monitored and stored at all times. After confirming that each vehicle-mounted power amplifier is working normally, manually observe the ammeter 108 corresponding to each vehicle-mounted power amplifier on the aging car, and confirm the current of the vehicle-mounted power amplifier again. After confirming that it is correct, push the aging car to the designated position in the aging room, turn on the locking switch of the wheel 110 of the aging car, so that the aging car cannot move, and the personnel withdraw from the aging room, turn on the timing function of the aging room, and start aging. If you need to replace the aging car amplifier with a new one, there is no need to replace the main structure such as the aging box. You only need to replace the line speed component. The replacement cost is low. The line speed component and the aging car are connected with the aviation plug through a heavy-duty connector. The replacement is convenient and fast, which solves the problem of difficulty in replacing products in the aging room and high temperature that can easily cause burns to people. It saves tooling and labor costs and improves production efficiency.

[0028] A positioning plate 501 and an aluminum shell heat dissipation resistor 502 are arranged in the aging box; the aluminum shell heat dissipation resistor 502 is fixed on the positioning plate 501.

[0030] The external A2B signal or CAN signal is input to the heavy-duty connector 207, and is distributed to the interface of each vehicle-mounted amplifier by the heavy-duty connector 207. The aging data of each vehicle-mounted amplifier is output to an external computer through the heavy-duty connector 208 for collection and analysis. A temperature alarm device 209 is provided for each box. Each vehicle-mounted amplifier in the box is equipped with an amplifier connection component on board, which includes: a heavy-duty connector 210 for signal transmission, an aviation plug 211 for power transmission, and an ammeter 212 for easy replacement and observation. The aging box is equipped with a separate fan switch 213, and the fan is powered separately to avoid affecting other signal transmissions.

[0031] In some embodiments, the multi-layer frame is a four-layer frame, and the material of the multi-layer frame includes aluminum alloy, etc. The frame of the multi-layer frame is a 40*40 European standard aluminum profile 401, which is connected by wildebeests, and four 8-inch silent rubber heavy-duty universal wheels with brakes 403 are connected below through a mounting plate 402.

[0032] like Figure 5 As shown, the positioning plate 501 in the aging box is fixed by positioning bolts. Hexagonal studs are used on the positioning plate to fix the aluminum shell heat dissipation resistor 502 in layers. The aluminum shell heat dissipation resistor 502 is used to simulate the working conditions of each channel of the vehicle amplifier. The aluminum shell heat dissipation resistor 502 is fixed in layers to effectively dissipate heat and occupy a small area. If the number of vehicle amplifier channels increases, it can also be easily improved.

[0033] The aluminum shell scattered resistor 502 is connected to the corresponding interface of the heavy-duty connector through a double-layer wiring trough 503. The power supply is connected to the high-temperature resistant junction box 506 after passing through a single-core high-current fast plug 504 and an overload circuit breaker protector 505, and each aviation plug is connected to each vehicle-mounted power amplifier power interface through the double-layer wiring trough 503 to ensure that the power line and the signal line are separated into two layers.

[0034] The bottom of the aging box is equipped with six powerful fans 507 connected to the temperature control collector 508 to control and collect and store the temperature, and a separate line is used to connect the temperature alarm. The internal power line uses a high-temperature resistant German standard low-voltage line, the main power line uses a high-temperature resistant silicone rubber multi-core soft line, and the signal transmission uses a high-temperature resistant shielded line.

[0035] The aging cart for the vehicle-mounted power amplifier in this embodiment solves the problems of difficulty in replacing products in the aging room and high temperature that may easily cause burns to personnel; the aging cart can be suitable for various vehicle-mounted power amplifiers by only replacing the line speed components, saving tooling and labor costs; aging data can be collected and analyzed during the aging process, and manual testing after aging is not required, saving tooling and labor costs; aging data can be traced back to each power amplifier, which facilitates management and improves production efficiency.
