Description

Technical Field

[0001] The present invention relates to the field of tooling and fixtures, and in particular to a shielding tooling for spraying new energy end plates. Background Art

[0002] The new energy end plate is one of the important structural components of the battery module's outer frame. The end plate and side plates are connected together by welding to maintain the pressure of the battery cells in the module. As the most important protection for module safety, the end plate structure must not only ensure that the overall structural strength of the module meets the requirements, but also have very strict requirements related to battery safety, such as the insulation, voltage resistance and flame retardancy of the surface coating. The new energy end plate includes an end plate body and a first end and a second end formed at both ends of the end plate. The surface of the end plate body serves as the spraying area, and the first end and the second end serve as the non-spraying area. During the spraying process, the first end and the second end need to be shielded to prevent the spraying material from entering the first end and the second end. In the traditional spraying process, high-temperature glue is manually applied to the non-spraying area for shielding. After the surface of the end plate body is sprayed, the high-temperature glue is manually removed. The disadvantages of this method are that it wastes manpower, takes a lot of time to shield the non-spraying area and remove the high-temperature glue, the operation is difficult, and the efficiency is extremely low.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0038] The shielding tool for spraying the new energy end plate of the present invention is used to shield the non-coating area of ​​the new energy end plate 100 during the spraying operation of the new energy end plate to prevent the spraying material from being sprayed onto the non-coating area. Figures 1 to 4 The new energy end plate 100 includes an end plate body 110 and a first end portion 120 and a second end portion 130 formed at both ends of the end plate body 110. The surface (upper surface) of the end plate body 110 is a coating area, and the first end portion 120 and the second end portion 130 are the non-coating areas.

[0039] The upper surface of the end plate body 110 is higher than the upper surfaces of the first end portion 120 and the second end portion 130, thereby making the end plate body 110 have a first end face facing the first end portion 120 and a second end face facing the second end portion 130, the lower edge of the first end face is vertically connected to the upper surface of the first end portion 120, and the lower edge of the second end face is vertically connected to the upper surface of the second end portion 130.

[0040] The first end portion 120 includes a first base plate 121, a first side plate 122 formed on one side of the first base plate 121 along the width of the new energy end plate 100, a second side plate 123 formed on the opposite side of the first base plate 121, and a first main body 124 formed on the first base plate 121 and located between the first side plate 122 and the second side plate 123. The lower surface of the first base plate 121 is coplanar with the lower surface of the end plate body 110, the first side plate 122 is coplanar with a first side surface on one lateral side of the end plate body 110, and the first side plate 122 protrudes from the end surface of the first base plate 121 away from the end plate body 110. The second side surface on the other lateral side of the end plate body 110 extends beyond the outer surface of the second side plate 123. A first U-shaped groove 125 is formed between the first main body 124 and the first side plate 122, and a second U-shaped groove 126 is formed between the first main body 124 and the second side plate 123. Since the upper surface of the first end portion 120 is lower than the upper surface of the end plate body 110, and since the first U-shaped groove 125 and the second U-shaped groove 126 pass through the upper surface of the first end portion 120 upward, the notch surfaces of the first U-shaped groove 125 and the second U-shaped groove 126 are lower than the upper surface of the end plate body 110.

[0041] Two first channels 1241 are spaced apart within the first main body 124 along the width of the new energy end plate 100. These channels 1241 are located inside the first and second U-shaped grooves 125, 126 and are arranged parallel to these grooves. These channels 1241 extend through the first main body 124, away from the end plate body 110, to communicate with the outside world. Two sets of second through-holes 1242 are formed on the upper surface of the first main body 124 of the first end portion 120, corresponding to the two first channels 1241. Both sets of second through-holes 1242 extend perpendicularly through the upper surface of the first main body 124 to communicate with the first channels 1241. Each set of second through-holes 1242 consists of at least one second through-hole 1242, with at least one second through-hole 1242 formed at the location of one of the first channels 1241 and at least one second through-hole 1242 formed at the location of the other first channel 1241. In this specific embodiment, each group of second through-holes 1242 includes two second through-holes 1242 , and the second through-holes 1242 , which form a group of two, are distributed on the first main body portion 124 in a matrix.

[0042] The upper surface of the first main body 124 is formed with three first steps 1243 that extend gradually downward, away from the end plate body 110. The top step, closest to the end plate body, has the largest tread, the bottom step, further away from the end plate body, has the second largest tread, and the middle step has the smallest tread. A first protrusion 1244 protrudes from the riser of the bottom step, near the first U-shaped groove 125, away from the end plate body 110. A second protrusion 1245 protrudes from the riser of the bottom step, near the second U-shaped groove 126, away from the end plate body 110. The first and second protrusions 1244 and 1245 form a first recessed portion 1246 between them on the riser of the bottom step, which is recessed toward the end plate body 110. A first inclined surface, inclined downward and away from the end plate body 110, is formed on the tread of the bottom step at one end, near the first recessed portion 1246. The first protrusion 1244 and the second protrusion 1245 protrude from the end surface of the first bottom plate 121 in a direction away from the end plate body 110, so that the lower surfaces of the first protrusion 1244 and the second protrusion 1245, the lower edge of the first side plate 122 and the end surface of the first bottom plate 121 are combined to form a first L-shaped positioning space 1247. The part of the first side plate 122 protruding from the first bottom plate 121, the first protrusion 1244 and the second protrusion 1245 together form a first positioning protrusion protruding in a direction away from the end plate body 110. The lower surface of the first positioning protrusion (i.e., the lower edge of the first side plate 122, the lower surface of the first protrusion 1244 and the lower surface of the second protrusion 1245) is a first positioning surface 1248 for preventing the first end face shielding portion from moving upward.

[0043] The second end portion 130 has the same structure or function as the first end portion 120. The second end portion 130 includes a second bottom plate, a third side plate 132 formed on one side of the second bottom plate along the width direction of the new energy end plate 100, a fourth side plate 133 formed on the other side of the second bottom plate, and a second main body portion 134 formed on the second bottom plate and located between the third side plate 132 and the fourth side plate 133. The lower surface of the second bottom plate is in the same plane as the lower surface of the end plate body 110. The third side plate 132 is in the same plane as the first side surface of the end plate body 110 on one lateral side, and the third side plate 132 protrudes from the end surface of the second bottom plate in a direction away from the end plate body 110. The second side surface of the end plate body 110 on the other lateral side is beyond the outer side surface of the fourth side plate 133. A third U-shaped groove 135 is formed between the second main body portion 134 and the third side plate 132, and a fourth U-shaped groove 136 is formed between the second main body portion 134 and the fourth side plate 133. Since the upper surface of the second end portion 130 is lower than the upper surface of the end plate body 110, and since the third U-shaped groove 135 and the fourth U-shaped groove 136 pass through the upper surface of the second end portion 130 upwardly, the groove opening surface of the third U-shaped groove 135 and the fourth U-shaped groove 136 is lower than the upper surface of the end plate body 110.

[0044] Two second holes (not shown in the figure) are spaced apart along the width direction of the new energy end plate 100 in the second main body portion 134. The two second holes are located inside the third U-shaped groove 135 and the fourth U-shaped groove 136, and are arranged in parallel with the third U-shaped groove 135 and the fourth U-shaped groove 136. The two second holes pass through the second main body portion 134 in a direction away from the end plate body 110 to communicate with the outside. The second hole close to the third U-shaped groove 135 is located on the same line as the first hole 1241 close to the first U-shaped groove 125, and the second hole close to the fourth U-shaped groove 136 is located on the same line as the first hole 1241 close to the second U-shaped groove 126. Two groups of third perforations 1342 are formed on the upper surface of the second main body portion 134 of the second end portion 130 at positions corresponding to the two second holes, respectively. The two groups of third perforations 1342 each pass through the upper surface of the second main body portion 134 in a vertical direction to communicate with the second holes. Each group of third perforations 1342 has at least one, i.e., at least one third perforation 1342 is formed at the position of one second hole, and at least one third perforation 1342 is formed at the position of the other second hole. In this specific embodiment, each group of third perforations 1342 has two, and the two third perforations 1342 in each group are arranged in a matrix on the second main body portion 134.

[0045] The upper surface of the second main body portion 134 is formed with three third steps 1343 that extend gradually downward, away from the end plate body 110. The top step, closest to the end plate body, has the largest tread, the bottom step, further away from the end plate body, has the second largest tread, and the middle step has the smallest tread. A third protrusion 1344 protrudes from the riser of the bottom step, near the third U-shaped groove 135, away from the end plate body 110. A fourth protrusion 1345 protrudes from the riser of the bottom step, near the fourth U-shaped groove 136, away from the end plate body 110. The third and fourth protrusions 1344 and 1345 form a second recessed portion 1346 between them on the riser of the bottom step, which is recessed toward the end plate body 110. A second inclined surface, sloping downward and away from the end plate body 110, is formed on the tread of the bottom step at one end, near the second recessed portion 1346. The third protrusion 1344 and the fourth protrusion 1345 protrude from the end face of the second bottom plate in a direction away from the end plate body 110, so that the lower surfaces of the third protrusion 1344 and the fourth protrusion 1345, the lower edge of the third side plate 132 and the end face of the second bottom plate are combined to form a second L-shaped positioning space (not shown in the figure). The part of the third side plate 132 protruding from the second bottom plate, the third protrusion 1344 and the fourth protrusion 1345 together form a second positioning protrusion protruding in a direction away from the end plate body 110. The lower surface of the second positioning protrusion (i.e., the lower edge of the third side plate 132, the lower surface of the third protrusion 1344 and the lower surface of the fourth protrusion 1345) is a second positioning surface (not shown in the figure) for preventing the second end face shielding portion from moving upward.

[0046] The end plate body 110 includes a first through-hole 111 formed therein, which communicates with the first U-shaped groove 125 and the third U-shaped groove 135. The first through-hole 111, the first U-shaped groove 125, and the third U-shaped groove 135 are all located in a straight line, forming a first passage extending through the length of the new energy end plate 100. The upper wall of the first through-hole 111 (the portion of the wall near the upper surface of the end plate body 110) is higher than the upper surfaces of the first end 120 and the second end 130, so that the upper wall of the first through-hole 111 is higher than the notch surfaces of the first U-shaped groove 125 and the third U-shaped groove 135. The end plate body 110 includes a second through-hole 112 formed therein, which communicates with the second U-shaped groove 126 and the fourth U-shaped groove 136. The second through-hole 112, the second U-shaped groove 126, and the fourth U-shaped groove 136 are all located in a straight line, forming a second passage extending through the length of the new energy end plate 100. The end plate body 110 includes a third through-hole 113 connected to one of the first channels 1241 and the corresponding second channel, forming a third channel that extends through the length of the new energy end plate 100. A fourth through-hole 114 is also formed in the end plate body 110, connecting to another of the first channels 1241 and the corresponding second channel, forming a fourth channel that extends through the length of the new energy end plate 100. The first, second, third, and fourth channels are spaced apart along the width of the new energy end plate 100, serving as both weight-reducing through-holes and cable routing channels. It should be understood that the two first channels 1241 and the two second channels described above are merely exemplary and described as a specific example. In other structures of the new energy end plate 100, the number of first channels 1241 and second channels is not limited to the above number. The number of channels corresponding to the two first channels 1241 and the two second channels also varies adaptively with the number of channels. For example, in one embodiment, there is one first channel 1241 and one second channel, and accordingly, there is also one channel formed.

The first shielding mechanism 200 includes a first end face shielding part 210 detachably covering an end face of the first end portion 120 and a first surface shielding part 220 connected with the first end face shielding part 210 and detachably covering a surface of the first end portion 120; and the second shielding mechanism 300 includes a second end face shielding part 310 detachably covering an end face of the second end portion 130 and a second surface shielding part 320 connected with the second end face shielding part 310 and detachably covering a surface of the second end portion 130.

[0048] The first end face shielding part 210 includes a first end face shielding plate 211 covering an end face of the first end portion 120 and a first positioning recess 212 formed on the first end face shielding plate 211 at a position corresponding to the first positioning protrusion. The first end face shielding plate 211 has a first convex surface 213 with a higher surface and a first concave surface 214 with a lower surface, which can form a "convex" shape or a stepped shape gradually downward away from the end plate body 110. An upper end (the first convex surface 213 and / or the first concave surface 214) of the first end face shielding plate 211 is formed with a first locking hole 211a for locking the first surface shielding part 220, which is an internally threaded hole or a clamping hole. The first positioning recess 212 has a first recess 212a for the first side plate 122 to extend into and two first U-shaped positioning grooves 212b for the first protruding portion 1244 and the second protruding portion 1245 to extend into, and a third positioning protrusion 215 formed between the two first U-shaped positioning grooves 212b and abutting against an inner concave surface of the first recessed portion 1246.

[0049] The first surface shielding part 220 includes a first surface shielding plate 221, a first panel 222 formed at an outer end of the first surface shielding plate 221 and connected with an inner side surface of the first end face shielding part 210, and a third insertion block 223 formed on a lower surface of the first surface shielding plate 221 at positions corresponding to the first U-shaped groove 125 and the second U-shaped groove 126.

[0050] The inner end surface of the first surface shield 221 abuts against the first end surface of the end plate body 110. The lower surface of the first surface shield 221 overlies the upper surface of the first end portion 120. The outer end of the first surface shield 221 is detachably connected to the upper end of the first end surface shielding portion 210. The inner end surface of the first surface shield 221 forms a third inclined surface 2211 that slopes downward and forward. This third inclined surface 2211 causes the height of the first surface shield 221 to decrease as it moves forward, reducing obstruction of the first end surface of the end plate body 110. On the lower surface of the first surface shield 221, a second concave surface 2212 is formed at a position corresponding to the first convex surface 213, while a second convex surface 2213 is formed at a position corresponding to the first concave surface 214. The first convex surface 213 and the second concave surface 2212, as well as the second convex surface 2213 and the first concave surface 214, cooperate in a concave-convex manner to provide positioning before assembly. A first through-hole 221a is formed on the first surface shield 221 at a position corresponding to the first locking hole 211a. During assembly, the second concave surface 2212 of the first surface shield 221 mates with the first convex surface 213 of the first end surface shield 211, and the second convex surface 2213 of the first surface shield 221 mates with the first concave surface 214 of the first end surface shield 211, to prevent displacement of the first surface shield 221. The first locking bolt 221b passes downward through the first through-hole 221a and then locks with the first locking hole 211a. Three matching second steps 2214 are formed on the lower surface of the first surface shield 221 at positions corresponding to the three first steps 1243. The risers of the second steps 2214 abut against the risers of the first steps 1243, and the treads of the second steps 2214 abut against the treads of the first steps 1243. The upper end of the first panel 222 is connected to the lower surface of the first surface shield 221 , and the lower end extends downward to abut against the upper surface of the third positioning protrusion 215 , and the outer side surface of the first panel 222 is tightly attached to the inner side surface of the first end shield 211 .

[0051] The third insert blocks 223 are two in number. One third insert block 223 extends downward from the lower surface of the first side of the first surface shield 221, and the other third insert block 223 extends downward from the lower surface of the second side of the first surface shield 221. The two third insert blocks 223 are inserted into the first U-shaped groove 125 and the second U-shaped groove 126, respectively. The outer surfaces of the two third insert blocks 223 are in close contact with the first side plate 122 and the second side plate 123, respectively. Both third insert blocks 223 have a first front protrusion 2231 that protrudes forward from the inner end surface of the first surface shield 221. The two first front protrusions 2231 are inserted into the first through hole 111 and the second through hole 112, respectively. The upper surfaces of the two first front protrusions 2231 are higher than the notch surfaces of the first U-shaped groove 125 and the second U-shaped groove 126, so as to abut against the upper wall of the first through hole 111 and the second through hole 112.

[0052] The first detachable connection structure includes a first insertion block 410 and a second locking bolt 420 formed below the first surface shield 221. The outer end of the first insertion block 410 is connected to the first end face shielding portion 220, and the inner end is inserted into the channel. A fourth through-hole 430 is formed on the first surface shielding portion 220 at a position corresponding to the second through-hole 1242. A second locking hole 440 is formed on the first insertion block 410 at a position corresponding to the second through-hole 1242. The second locking bolt 420 sequentially penetrates the fourth through-hole 430 and the second through-hole 1242 from top to bottom and then locks with the second locking hole 440. In this embodiment, two first insertion blocks 410 are formed below the first surface shield 221, and the inner ends of the two first insertion blocks 410 are inserted into the third channel and the fourth channel, respectively. A second locking bolt 420 is inserted through the fourth through-hole 430 and then locked with the second locking hole 440 on one of the first insert blocks 410. Alternatively, two second locking bolts can be inserted through the two fourth through-holes 430 and then locked with the second locking holes 440 on the two second insert blocks. The outer end of the other first insert block 410 is inserted into the first end shield 211 and connected to a hook 224. During the spraying operation, the end with the hook 224 is considered the upper end and can be hung on the hanging rod, so that the new energy end plate 100 and the shielding tool are hung vertically on the hanging rod for spraying.

[0053] The structure and function of the second end face shielding portion 310 are the same as or similar to the structure or function of the first end face shielding portion 210. The second end face shielding portion 310 includes a second end face shield covering the end face of the second end portion 130 and a second positioning recess formed on the second end face shield at a position corresponding to the second positioning protrusion. The upper end face of the second end face shield also has a first convex surface of a higher surface and a first concave surface of a lower surface. The first convex surface and the first concave surface of the second end face shield can form a "convex" shape, or can form a step-by-step downward shape away from the end plate body 110. The upper end of the second end face shield is also formed with a first locking hole for locking the second surface shielding portion 320. The first locking hole on the second end face shield is an internal threaded hole or a card hole. The second positioning recess has a fourth positioning surface that abuts the second positioning surface. The second positioning recess has a second groove for the third side plate 132 to extend into, and two second U-shaped positioning grooves for the third protrusion 1344 and the fourth protrusion 1345 to extend into. A fourth positioning protrusion (with the same structure as the third positioning protrusion) is formed between the two second U-shaped positioning grooves and abuts against the inner concave surface of the second recess 1346. The bottom surface of the second U-shaped positioning groove and the bottom surface of the second groove serve as the fourth positioning surface and extend into the second L-shaped positioning space to abut against the second positioning surface.

[0054] The second surface shielding portion 320 includes a second surface shield, a second panel formed at the outer end of the second surface shield and connected to the inner side surface of the second end face shielding portion 310, and a fourth insertion block formed on the lower surface of the second surface shield at a position corresponding to the third U-shaped groove 135 and the fourth U-shaped groove 136.

[0055] The inner end face of the second surface shield abuts against the second end face of the end plate body 110, the lower surface of the second surface shield covers the upper surface of the second end portion 130, and the outer end of the second surface shield is detachably connected to the upper end of the second end face shielding portion 310. The inner end face of the second surface shield forms a fourth inclined surface that is inclined downward and forward. The fourth inclined surface causes the height of the second surface shield to decrease as it moves forward, thereby reducing the obstruction of the second end face of the end plate body 110. A matching multi-step fourth step is formed on the lower surface of the second surface shield at a position corresponding to the multi-step third step 1343. The riser of the fourth step abuts against the riser of the third step 1343, and the tread of the fourth step abuts against the tread of the third step 1343. A second concave surface is formed upwardly on the lower surface of the second surface shield at a location corresponding to the first convex surface of the second end shield, and a second convex surface is formed downwardly at a location corresponding to the first concave surface of the second end shield. The first convex surface of the second end shield engages with the second concave surface of the second surface shield, and the second convex surface of the second surface shield engages with the first concave surface of the second end shield, to provide positioning prior to assembly. A first through-hole is also formed on the second surface shield at a location corresponding to the first locking hole on the second end shield. During assembly, the second concave surface of the second surface shield engages with the first convex surface of the second end shield, and the second convex surface engages with the first concave surface of the second end shield, to prevent displacement of the second surface shield, allowing the first locking bolt to pass downwardly through the first through-hole of the second surface shield and engage with the first locking hole. The upper end of the second panel is connected to the lower surface of the second surface shield, and the lower end extends downward to abut against the upper surface of the fourth positioning protrusion. The outer side of the second panel is closely abutted against the inner side of the second end shield.

[0056] The fourth insert blocks are two in number, one of which is formed by extending downward from the lower surface of the first side of the second surface shield, and the other is formed by extending downward from the lower surface of the second side of the second surface shield. The two fourth insert blocks are respectively inserted into the third U-shaped groove 135 and the fourth U-shaped groove 136, and the outer side surfaces of the two fourth insert blocks are respectively in close contact with the third side plate 132 and the fourth side plate 133. The two fourth insert blocks each have a second front protrusion that protrudes forward from the inner end surface of the second surface shield. The two second front protrusions are respectively inserted into the first through hole 111 and the second through hole 112, and the upper surfaces of the two second front protrusions are both higher than the notch surfaces of the third U-shaped groove 135 and the fourth U-shaped groove 136 so as to abut against the upper hole walls of the first through hole 111 and the second through hole 112.

[0057] The second detachable connecting structure comprises a second insertion block formed below the second surface shielding part 320 and a third locking bolt, the outer end of the second insertion block is connected with the second end surface shielding plate, and the inner end is inserted into the channel, the second surface shielding part 320 (second surface shielding plate) is formed with a fifth through hole 530 at a position corresponding to the third through hole 1342, the second insertion block is formed with a third lock hole at a position corresponding to the third through hole 1342, and the third locking bolt is sequentially inserted into the fifth through hole 530 and the third through hole 1342 from top to bottom and locked with the third lock hole. In the embodiment, since the first end part 120 and the shielding mechanism thereof serve as the upper end and are provided with the hook 224, the second end part 130 and the shielding mechanism thereof serve as the lower end, and the hook 224 is not required, therefore, the second insertion block only needs one, and the inner end of the second insertion block is inserted into the third channel or the fourth channel.

Adjusting the position of the first surface shielding plate 221 in the width direction of the new energy end plate 100 to align the first through hole 221a with the first lock hole 211a; 4. Screwing the first locking bolt 221b into the first lock hole 211a;

[0060] 2. Insert the first shielding mechanism 200 (the assembled first end shield 211 and the first surface shield 221) along the length direction of the new energy end plate 100: 1. Align the two third insertion blocks 223 with the first U-shaped groove 125 and the second U-shaped groove 126 respectively; 2. Insert the two third insertion blocks 223 into the first U-shaped groove 125 and the second U-shaped groove 126 respectively and use them as a guide to drive the first surface shield 221 to gradually cover the upper surface of the first end portion 120, and at the same time drive the first end shield 211 to gradually approach the end surface of the first end portion 120; 3. Align the first forward convex portions of the two third insertion blocks 223 respectively Entering the first through hole 111 and the second through hole 112 to abut against their upper hole walls; when the two first forward protrusions are inserted into the first through hole 111 and the second through hole 112, the first U-shaped positioning groove 212b and the first groove 212a on the inner side of the first end face shield 211 are mated with the first positioning protrusion, and the third positioning surface 212c abuts against the first positioning surface 1248; at the same time, the first insertion block 410 is also inserted into the channel, and the second locking hole 440 on the first insertion block 410, the fourth through hole 430 on the first surface shielding portion 220, and the second through hole 1242 on the upper surface of the first end portion 120 are all aligned;

[0061] 3. Assembly: Screw the second locking bolt 420 into the second locking hole 440 to detachably assemble the first shielding mechanism 200 to the first end portion 120 of the new energy end plate 100;

[0062] 4. Assemble the second shielding mechanism 300 according to the above assembling methods 1 to 3.

[0063] Compared with the traditional heating glue masking method, the shielding tool for spraying the new energy end plate of the present invention can be detachably shielded in the non-coating area of ​​the new energy end plate. It is made once and can be reused countless times, which greatly reduces the spraying cost; the shielding tool can be assembled to the corresponding non-coating area through a locking bolt, and the disassembly and assembly time is short, the disassembly and assembly efficiency is high, and manpower and material resources are greatly saved; the U-shaped groove of the new energy end plate is used as a guide, and the corresponding guide insertion blocks (the third insertion block and the fourth insertion block) are designed, which makes the assembly process simpler, further shortens the assembly time, and improves the assembly efficiency; the surface shield can not only fully shield the upper surface of the end, but also When the shielding mechanism is inserted into the end portion, the lower surface of the surface shield cooperates with the upper surface of the end portion, and the third insertion block and the fourth insertion block cooperate with the upper hole wall of the corresponding through hole, so that the upper surface of the end portion serves as the lower limit of the shielding mechanism, and the upper hole wall of the corresponding through hole serves as the upper limit of the shielding mechanism. In the process of inserting the shielding mechanism into the end portion, the shielding mechanism is always limited at the required horizontal height, so that when the forward convex portion of the shielding mechanism is inserted into the corresponding through hole, the corresponding positioning convex portion on the corresponding end portion is matched with the corresponding positioning concave portion on the corresponding end face shield, so that the insertion into the through hole can be positioned immediately, further saving assembly time and making the entire assembly process more worry-free and labor-saving.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
