Description

Technical Field

[0001] The present invention belongs to the technical field of thermal batteries, and in particular relates to an auxiliary tooling and an auxiliary method for a thermal battery electrical assembly process. Background Art

[0002] Thermal batteries have a variety of installation structures, and are generally connected to the cabin body through a mounting frame structure. The mounting frame structure includes an upper pressure plate, a lower pressure plate, a docking column and screws. The unit battery is located between the upper pressure plate and the lower pressure plate, and the docking column is located between the upper pressure plate and the lower pressure plate. The screws pass through the upper pressure plate, the docking column and the lower pressure plate to fasten the unit battery in the space formed by the upper pressure plate, the lower pressure plate and the docking column. The unit battery terminal is welded with wires and then sealed with glue, and then the upper cover is installed on the surface of the upper pressure plate for protection. When the mounting frame structure is connected to the cabin body, depending on the actual structure of the cabin body, it may be connected to the cabin body by the lower pressure plate or the lower pressure plate.

[0003] To save space, the electrical connector serving as the power input and output channel is installed on the upper cover plate on the upper part of the mounting frame. During the electrical connection operation between the electrical connector and the unit battery terminal, since there is no place to place the upper cover plate, it needs to be held manually, which increases the difficulty of operation. In addition, the upper cover plate cannot be avoided from being moved during the electrical installation process, and the wires on the terminal are easily pulled and damaged, posing a hidden danger to subsequent use. Summary of the invention

[0004] The technical problem solved by the present application is: to overcome the deficiencies of the prior art, to provide a thermal battery electrical assembly process auxiliary tooling, and to improve the reliability of thermal battery products with top fixed electrical connectors.

[0005] The present invention uses a thermal battery electrical installation process auxiliary tooling, which clamps the tooling on an upper pressure plate and places an upper cover on the tooling, thereby reducing the difficulty of operation. At the same time, the position of the upper cover remains fixed during the entire electrical installation and glue filling process, which can effectively avoid damage to the connecting wires and improve product reliability.

[0006] The technical solutions provided by this application are as follows:

A slot is opened on the side of pressing block I facing away from pressing block II, and the upper cover plate is arranged in the slot.

[0008] When the pan head screw is connected between the pressure block I and the pressure block II, a step is provided on one side of the pressure block I and the pressure block II that are opposite to each other and used to clamp the upper pressure plate, so that the distance between the relative surfaces of the pressure block I and the pressure block II that clamp the upper pressure plate is greater than the distance between the relative surfaces of the pressure block I and the pressure block II through which the pan head screw passes.

[0009] Along the direction in which the pressing block I and the pressing block II are inserted into the outside of the upper pressing plate, the middle parts of the pressing blocks I and II are screwed with pan head screws.

[0012] The opposing surfaces and step surfaces of the pressing blocks I and II clamping the upper pressing plate are pasted with a protective layer.

[0013] The side of the pressing block I facing away from the pressing block II is slidably connected with a pressing plate, the sliding direction of the pressing plate is parallel to the width direction of the slot, the pressing plate is located in the slot, and a pressing spring is arranged between the pressing plate and an inner wall of one side of the slot.

[0014] The clamping plate is connected to a limiting rod, which is parallel to the sliding direction of the clamping plate. The pressing block I is provided with a limiting hole, and the limiting rod is located in the limiting hole and is slidably connected to the pressing block I.

[0015] The limiting rod is provided with a positioning tooth, and the pressure block I is provided with a positioning hole.

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments disclosed in the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] The present application embodiment discloses a thermal battery electrical process auxiliary tooling and auxiliary method, such as Figure 1As shown, it is used for a thermal battery mounting structure, which is connected to the cabin, and the thermal battery mounting structure includes an upper pressure plate, a lower pressure plate, a connecting structure and an upper cover plate, and the connecting structure includes a docking column and a screw, the unit battery is located between the upper pressure plate and the lower pressure plate, the docking column is located between the upper pressure plate and the lower pressure plate, and the screw passes through the upper pressure plate, the docking column and the lower pressure plate, and the unit battery is fastened in the space formed by the upper pressure plate, the lower pressure plate and the docking column. The unit battery terminal is welded with wires and then sealed with glue, and then the upper cover plate is installed on the surface of the upper pressure plate for protection, and the electrical connector as the power input and output channel is installed on the upper cover plate, and the wires need to be welded between the electrical connector and the unit battery terminal.

[0027] The auxiliary tooling includes a pressing block I1, a pressing block II2 and a pan head screw 3.

[0028] A through hole is opened in the pressure block I1, and a threaded hole is opened in the pressure block II2. The two are assembled together by a pan head screw 3. Preferably, the pressure block I1 and the pressure block II2 are both made of aluminum alloy; after the pressure block I1 and the pressure block II2 are combined, the opening can clamp the upper pressure plate, and preferably, the opening depth is 5mm; the upper pressure plate of different thicknesses can be matched by adjusting the pan head screw 3, and preferably, the thickness range is adjusted to 12mm~18mm; flexible adjustment pads 4 are attached to the inner sides of the tail ends of the pressure blocks I1 and II2, and the support tooling matches the thickness of the upper pressure plate. Preferably, the flexible adjustment pad is a foam pad. After replacing the flexible adjustment pads 4 of different thicknesses, the size of the opening can be adjusted after the pressure block I1 and the pressure block II2 are combined to clamp the upper pressure plate of different thicknesses; a protective layer 5 is attached to the inner side of the opening after the pressure block I1 and the pressure block II are combined, and preferably, the protective layer 5 is fiber felt to prevent the upper pressure plate from being clamped; a card slot 11 is provided on the outer side of the tail end of the pressure block I1 to place the upper cover plate, and preferably, the slot width is 5mm and the corners are rounded.

[0029] Helper methods include:

[0030] At least two sets of auxiliary tooling for the electrical assembly process of the thermal battery of the present invention are used together. When in use, the pressure blocks I1 and II2 of the two sets of auxiliary tooling can clamp the same side of the horizontal upper platen at the adjustable opening, and after adjusting the pan head screw 3 to fasten the pressure blocks I1 and II2 to one side of the upper platen, the upper cover plate is placed in the card slot 11 of the pressure block I1, and then the electrical connector on the upper cover plate is electrically connected to the unit battery, and glue is poured, etc. After the glue is solidified, the pan head screw 3 is loosened and the tooling is removed. Subsequent operations can be performed, and since the protective layer 5 is attached to the inner side of the tooling, the clamping position of the upper platen will not be damaged.

[0031] The above-mentioned auxiliary tooling and auxiliary methods can reduce the difficulty of operation, while ensuring that the relative position of the upper cover plate and the connecting wires on the terminal will not change during the electrical installation and glue filling process, which can effectively prevent the connecting wires from moving and being damaged, thereby improving product reliability.

[0032] Example 2

[0033] like Figure 2 and Figure 3 As shown, based on the auxiliary tooling of Example 1, a pressing plate 6 is slidably connected to the side of the pressing block I1 away from the pressing block II2, the sliding direction of the pressing plate 6 is parallel to the width direction of the slot, the pressing plate 6 is located in the slot, and a pressing spring is arranged between the pressing plate 6 and an inner wall of one side of the slot.

[0034] The clamping plate 6 is connected to a limiting rod 61 , which is parallel to the sliding direction of the clamping plate 6 . The pressing block I1 is provided with a limiting hole, and the limiting rod 61 is located in the limiting hole and is slidably connected to the pressing block I1 .

[0035] The limiting rod 61 is provided with positioning teeth. Along the direction close to the clamping plate 6, the distance between the surface of each positioning tooth and the axis of the limiting rod 61 gradually increases. The pressing block I1 is provided with a positioning hole. One end of the positioning hole is connected to the limiting hole. A positioning rod is provided in the positioning hole. The positioning rod includes a screw 71, a positioning block 72 and a positioning spring 73. The positioning block 72 is slidably connected in the positioning hole. The positioning block 72 rotates and slides with the screw 71. The positioning spring 73 is located between the screw 71 and the positioning block 72 to push the positioning block 72 to be clamped between the positioning teeth. The screw 71 is threadedly connected to the pressing block I1. The shape of the end of the positioning block 72 facing the limiting rod 61 is engaged with the positioning teeth.

[0036] The screw rod 71 rotates to drive the positioning block 72 to move linearly in the positioning hole, thereby driving the positioning block 72 to disengage from the positioning teeth, or driving the positioning block 72 to be stuck between the positioning teeth.

[0037] When the positioning block 72 is inserted between the positioning teeth, the clamping plate 6 is pushed, and the clamping plate 6 can move toward one side of the clamping slot of the clamping block I1 and compress the clamping spring. At this time, as the clamping plate 6 moves, the positioning block 72 moves along the surface of the positioning teeth away from the limit rod 61 and compresses the positioning spring 73 until the positioning block 72 is separated from one positioning block 72, and the positioning block 72 is pushed by the positioning spring 73 to be inserted between the adjacent positioning teeth. In this process, the clamping plate 6 can only move in one direction and cannot move in the opposite direction. When the clamping plate 6 is close to one side of the clamping block I1, there is a large space between the clamping plate 6 and the other side of the clamping slot of the clamping block I1, which facilitates the upper cover plate to be placed between the clamping plate 6 and the other side of the clamping slot of the clamping block I1.

[0038] After the upper cover is placed in the slot, the screw 71 is rotated, the screw 71 drives the positioning block 72 to disengage from the positioning tooth, and the clamping spring pushes the clamping plate 6 to move until the clamping plate 6 clamps the upper cover, so that the slot of the auxiliary tooling can be used for upper covers of different thicknesses.
