Description

Height measuring tool for shell heat radiation boss

Technical Field

The application relates to the technical field of chip heat dissipation, in particular to a height measuring tool for a shell heat dissipation boss.

Background

In the field of automotive controllers, particularly in the current introduction of multi-domain converged automotive electronics and electrical architecture, each controller is populated with a number of high-power chips, and the system around it is also matched to a number of high-power devices. For these devices, a corresponding heat dissipation boss design is required to be made on the internal structure of the controller, and then a heat conducting medium is coated between the chip and the heat dissipation boss to conduct out the heat generated during the operation of the controller. The number of high-power devices in the high-power controller is large, and the number of corresponding heat dissipation bosses is also large.

In the design of the heat dissipation boss, the height is one of the most important index characteristics: if the boss is too high, the boss can be propped against the corresponding chip, so that the chip is damaged; if the boss is too short, the thickness of the heat conducting medium between the chip and the boss can be increased, so that the heat resistance of the heat conducting medium can be increased, even the heat conducting medium cannot be effectively attached to the boss and the surface of the chip, and finally the heat radiation performance of the chip is affected, so that the functions and the safety of the product are damaged. Therefore, strict detection and control are required for the high precision of the bosses, so that the realization of the due functions of the bosses is ensured.

Currently, a height gauge is generally used for measuring the height of the boss, but the method has the following defects for measuring the height and the size of the boss of some controllers with multiple bosses inside:

1. the operation platform of the height gauge has limited size, so that special sizes cannot be guaranteed, and smooth placement and size measurement of large-size devices are not facilitated;

2. when the product cannot be horizontally placed, the height gauge cannot measure the height of the boss of the product;

3. when the placement surface of the measured product is not parallel to each measured heat dissipation boss plane, the height position of each heat dissipation boss plane relative to the large plane of the height gauge cannot be fixed, so that measurement cannot be performed;

4. when the heights of one heat dissipation boss are measured, and then the heights of other heat dissipation bosses are measured, the measured product is required to be moved to enable the new measured heat dissipation boss to correspond to the position of the height gauge probe, and in the moving process, the position of the height reference is moved no matter the local size difference of the product is caused, or the influence of vibration caused in the moving process on the size precision of the probe can possibly cause deviation of the measurement result of the new heat dissipation boss;

5. the heights of a plurality of radiating bosses in the product are required to be measured, the positions of the product are required to be continuously and repeatedly adjusted, and the measuring efficiency is also very low;

6. the height standard of the heat dissipation boss in the controller is usually a standard formed by a plurality of standard facet surfaces and screw locking planes corresponding to chips, but the height gauge measuring method is usually only capable of comparing the height difference of the boss and the adjacent standard facet surfaces, so that the height difference of each standard facet surface and each standard facet surface is ignored, and the measuring result is not hundred percent accurate.

Referring to fig. 1 to 5, an embodiment of the present application provides a height measuring tool 10 for a housing heat dissipating boss, wherein the height measuring tool 10 includes a reference frame 100, a slide rail 200, and a measuring member 300. Further, referring to fig. 6 and 7, the reference frame 100 has a measurement reference plane 100b and an auxiliary plane 100a sequentially distributed along a first preset direction, the measurement reference plane 100b is parallel to the auxiliary plane 100a, and the measurement reference plane 100b is attached to the planes of all the screw holes 20a on the housing 20; the measuring piece 300 can move on the plane where the auxiliary surface 100a is located through the sliding rail 200, the measuring piece 300 can also move on the sliding rail 200 along a first preset direction, a height identification area 300a is arranged on the measuring piece 300, and a reading reference surface 200a parallel to the measuring reference surface 100b is arranged on the sliding rail 200; when the measuring member 300 moves along the first preset direction to contact the heat dissipating boss 20b on the housing 20, the reading reference surface 200a points to the corresponding scale in the height identification area 300a, and the scale in the height identification area 300a is used for indicating the height of the heat dissipating boss 20b relative to the measuring reference surface 100 b.

The height measuring tool 10 described above may be used in a housing 20 for electronic devices, such as a controller or other electronic device requiring heat dissipation. Referring to fig. 8, a plurality of heat dissipating bosses 20b and a plurality of screw holes 20a may be disposed in the housing 20 of the controller, and a circuit board or chip may be mounted to the corresponding screw holes 20a by screws to achieve fixation, wherein the screw holes 20a may be disposed at intervals along the direction of the edge of the housing 20 and/or in the middle region of the housing 20. The planes of all the screw holes 20a on the housing 20 are located in the same plane.

The following describes how the height of the heat radiation boss 20b of the controller case 20 is measured by the height measuring tool 10, taking the controller as an example:

the reference bracket 100 is first assembled to the housing 20 of the controller, and specifically, the measurement reference surface 100b of the reference bracket 100 is fitted to the plane of all the screw holes 20a of the housing 20. Then, the measuring piece 300 is moved on the plane where the auxiliary surface 100a of the reference frame 100 is located by using the sliding rail 200, and when the measuring piece 300 corresponds to the heat dissipation boss 20b to be measured, the measuring piece 300 is slid along the first preset direction (i.e. the vertical direction from top to bottom shown in fig. 1). When the measuring member 300 contacts the heat dissipating surface (i.e., the surface relatively close to the circuit board/chip) of the heat dissipating boss 20b, the reading reference surface 200a on the sliding rail 200 points to the scale 300a1 on the height marking area 300a of the measuring member 300, and the scale 300a1 is the height of the heat dissipating boss 20b relative to the measuring reference surface 100b of the reference frame 100. Since the measurement reference surface 100b of the reference bracket 100 coincides with the plane of the screw holes 20a of the housing 20, the height of the heat dissipation boss 20b relative to the measurement reference surface 100b of the reference bracket 100 is the height of the heat dissipation boss 20b relative to the plane of all the screw holes 20a on the housing 20. When the height of the next heat dissipating boss 20b is measured, the measuring member 300 is moved by the sliding rail 200, and then the measuring member 300 is used for measuring.

Wherein, a plurality of height measuring tools 10 with different specifications can be designed according to different production batches of the controller. When measuring the height of the heat dissipating boss 20b within the housing 20 of a certain production lot of controllers, a matched height measuring tool 10 may be selected to ensure measurement accuracy.

As can be seen, in the height measuring tool 10 for the heat dissipating boss 20b of the housing 20, the reference bracket 100 can be directly assembled to the housing 20, the heat dissipating boss 20b of the housing 20 can be measured without the housing 20 being horizontally arranged, the measuring member 300 can be moved on the plane of the auxiliary surface 100a of the reference bracket 100 by the sliding rail 200, the height of any heat dissipating boss 20b in the housing 20 can be measured, and when measuring the heights of different heat dissipating bosses 20b, the measuring reference surface 100b of the reference bracket 100 is always attached to the plane of all screw holes 20a in the housing 20, so that the measuring reference surface 100b adopted by different heat dissipating bosses 20b is the same reference surface when measuring the heights, thereby ensuring the measuring precision of different heat dissipating bosses 20 b.

In summary, the height measuring tool 10 not only can rapidly measure the heights of the plurality of heat dissipation bosses 20b, but also can ensure the measurement accuracy of each time.

Referring to fig. 9, in some embodiments of the present application, the height marking area 300a has a plurality of graduation marks distributed at intervals along the first preset direction, and the magnitude of the value corresponding to the graduation marks increases gradually along the direction from the measurement reference surface 100b to the auxiliary surface 100a, where the distance between the position of the zero graduation mark 300a1 on the height marking area 300a and the bottom surface 300b of the measuring element 300 (i.e. the end surface for contacting the heat dissipating boss 20 b) is equal to the distance between the reading reference surface 200a and the measurement reference surface 100 b. So arranged, the measurement of the height of the heat dissipating boss 20b is facilitated. Note that, the zero graduation mark 300a1 refers to a graduation mark having a value of 0.

Optionally, the end surface of the sliding rail 200 remote from the measurement reference surface 100b is a reading reference surface 200a. The reading datum 200a is configured such that a measurement person can read the scale value that the reading datum 200a points to on the altitude identification area 300a.

The scale values can be set on the measuring piece 300 in an integrated mode of printing, carving and the like, and also can be directly embedded into a ready-made ruler on the measuring piece 300.

Referring to fig. 6, in some embodiments of the present application, the reference frame 100 is provided with a mounting portion 120, and the mounting portion 120 is detachably connected to the housing 20. Thus, the reference bracket 100 can be fixed on the housing 20, and the reference bracket 100 can be prevented from shaking during the process of measuring the height of the heat dissipation boss 20b, so that the measurement accuracy can be ensured.

Referring to fig. 6, the mounting portion 120 may be a stud, and the mounting portion 120 is connected to a corresponding screw hole 20a of the housing 20 by a screw member, wherein an end surface of the mounting portion 120 adjacent to the corresponding screw hole 20a of the housing 20 is flush with the measurement reference surface 100 b. This facilitates connection of the mounting portion 120 to the housing 20.

The number of the mounting portions 120 may be the same as the number of the screw holes 20a in the housing 20, and the mounting portions 120 may be distributed in the same manner as the screw holes 20a in the housing 20. For example, referring to fig. 8, the number of screw holes 20a in the case 20 is 7, wherein 6 screw holes 20a are provided at intervals at the peripheral edge of the case 20, and 1 screw hole 20a is provided at the middle of the case 20; the number of the mounting parts 120 shown in fig. 6 is 7, in which 6 mounting parts 120 are provided at intervals at the circumferential edge of the reference frame 100, and 1 mounting part 120 is provided at intervals at the middle of the reference frame 100.

The mounting portion 120 may be integrally formed with the reference frame 100, or may be adhered thereto.

Referring to fig. 6, in some embodiments of the present application, the reference frame 100 is a bezel structure. The reference bracket 100 of the frame structure can avoid shielding the heat dissipation bosses 20b in the guarantee housing 20, so that the height of each heat dissipation boss 20b can be measured conveniently.

The shape of the frame structure may be set according to the shape of the edge of the housing 20, referring to fig. 8, if the shape of the edge of the housing 20 is rectangular, the shape of the frame structure shown in fig. 6 is also rectangular.

Referring to fig. 6, the middle of the reference frame 100 may be provided with a beam 130, and the beam 130 is used to provide the mounting portion 120. When the screw hole 20a is provided in the middle of the housing 20, the mounting portion 120 of the beam 130 of the reference frame 100 can be coupled to the screw hole 20a in the middle of the housing 20. Wherein, the beam 130 may be disposed along a second predetermined direction.

Referring to fig. 1, in some embodiments of the present application, a sliding rail 200 is movably disposed on the auxiliary surface 100a of the reference frame 100 along a second preset direction, and a measuring member 300 is movably disposed on the sliding rail 200 along a third preset direction, wherein the second preset direction is perpendicular to the third preset direction. The second preset direction may be the Y direction shown in fig. 1, and the third preset direction may be the X direction shown in fig. 1. So arranged, the measuring member 300 is conveniently moved arbitrarily on the plane in which the auxiliary surface 100a of the reference frame 100 is located.

Further, referring to fig. 1 and 6, in some embodiments of the present application, a plurality of limiting ribs 110 distributed along a second preset direction are further disposed on the auxiliary surface 100a of the reference bracket 100, the sliding rail 200 is disposed between two corresponding limiting ribs 110, and the limiting ribs 110 are used for limiting the sliding rail 200 in a third preset direction. The limiting rib 110 can ensure that the sliding rail 200 can move along the second preset direction.

Regarding the number of the limit ribs 110, it may be set according to the structure of the reference frame 100. For example, referring to fig. 6, if the reference bracket 100 is in a frame structure and the middle part is provided with the beams 130 distributed along the second preset direction, the number of the limiting ribs 110 may be three, where two limiting ribs 110 are disposed on the frame strips of the reference bracket 100 distributed along the second preset direction, and another limiting rib 110 is disposed on the beams 130 in the middle part of the reference bracket 100.

The limit rib 110 may be integrally formed or welded to the auxiliary surface 100a of the reference frame 100.

Further, referring to fig. 10, the slide rail 200 is provided with a guide hole 200b for moving the measuring member 300 in a third preset direction. The sliding rail 200 of this structure is simple in structure and also facilitates the movement of the measuring member 300.

It should be noted that the width of the guiding hole 200b may be slightly larger than the width of the measuring member 300, so that the measuring member 300 can be effectively ensured to move along the third preset direction.

Referring to fig. 10, the sliding rail 200 may have a block shape.

Referring to fig. 9, in some embodiments of the present application, the measuring member 300 includes a holding portion 310 and a measuring portion 320 connected to each other, the holding portion 310 has an outer diameter larger than that of the measuring portion 320, and a height identification area 300a is provided on the measuring portion 320. The large diameter grip 310 facilitates the measurer to grip the post and facilitate measurement. It should be noted that the measuring member 300 of the measuring member 300 may move in the guide hole 200b along the third predetermined direction.

The width of the grip portion 310 may be greater than the width of the guide hole 200b.

In the present application, the reference frame 100, the slide rail 200, and the measuring member 300 of the height measuring tool 10 may be made of a material having good wear resistance and high rigidity, such as metal (aluminum alloy, steel, etc.). This makes the height measuring tool 10 less likely to deform, ensuring the accuracy of the measurement.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
