The heat dissipation plate has the beneficial effects that the quick adjustment assembly is installed between the first heat dissipation clamping plate and the second heat dissipation clamping plate, so that when the heat dissipation plate is used, a transmission rod can be rotated by rotating a hand wheel in the quick adjustment assembly, and rotation of a corresponding first screw rod is achieved by means of two belts while the transmission rod rotates; after the screw rod I rotates, the sliding plate can conveniently extend out of the sliding cavity under the action of thread transmission, so that the size of the mounting space between the heat dissipation clamping plate I and the heat dissipation clamping plate II can be quickly adjusted; due to the fact that the size of the installation space between the first heat dissipation clamping plate and the second heat dissipation clamping plate can be rapidly adjusted only through one-time rotation in the adjusting mode, the tedious operation that fixing bolts are repeatedly screwed for fixing is avoided; therefore, the clamping and fixing efficiency of the detachable heat dissipation hanging plate for the water-cooling row of the automobile lithium battery pack and the automobile lithium battery is improved, and efficient installation and use of the heat dissipation plate are facilitated.

Description

Technical Field

[0001] The utility model relates to the field of water-cooled radiators for automobile lithium batteries, and particularly relates to a detachable heat dissipation plate for a water-cooled radiator of an automobile lithium battery pack. Background Art

[0002] As a power supply component of new energy vehicles, the lithium battery pack realizes an electric drive driving mode. When installing the lithium battery pack, a heat dissipation hanging plate needs to be equipped to fix it, and at the same time, a water-cooled radiator space is reserved for heat dissipation.

[0003] Chinese Patent with the publication number CN210926226U discloses a detachable heat dissipation hanging plate for a water-cooled radiator of an automobile lithium battery pack, which includes a first plate body and a second plate body. The longitudinal cross-sectional shapes of the first plate body and the second plate body are both concave, and clamping grooves are provided on the inner surface positions of the first plate body and the second plate body. A heat-conducting silica gel pad is coated on the outer surface of the clamping groove. Connecting plates are welded at the top and bottom positions on the outer wall of the first plate body close to the second plate body, and a plurality of groups of screw holes are provided between the front and rear surface positions of the connecting plates. The plurality of groups of screw holes are horizontally distributed. Guide cavities are provided at the top and bottom positions on the side wall of the second plate body close to the first plate body, and the guide cavities are horizontally installed.

[0004] Although the detachable heat dissipation hanging plate for a water-cooled radiator of an automobile lithium battery pack described in the above patent can clamp and fix automobile lithium batteries of different sizes during use and shock-absorb and dissipate heat from the installed automobile lithium batteries, when clamping and fixing the automobile lithium battery with the detachable heat dissipation hanging plate for a water-cooled radiator of the above structure, the size of the heat dissipation plate is mainly adjusted and limited by manual pulling and screwing the bolts twice. Since the processes of plugging and unplugging and screwing the bolts are relatively cumbersome, the clamping and fixing efficiency of the detachable heat dissipation hanging plate for a water-cooled radiator of the above structure with the automobile lithium battery is relatively low, which is not convenient for the efficient installation and use of the heat dissipation plate. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a detachable heat dissipation plate for a water-cooled radiator of an automobile lithium battery pack that can quickly adjust and limit the size between the first heat dissipation clamping plate and the second heat dissipation clamping plate during a single rotation process in view of the current situation of the prior art.

[0006] The utility model is implemented through the following technical scheme: the utility model proposes a detachable heat sink for a car lithium battery pack water cooling row, comprising a heat dissipation clamp plate 1, a heat dissipation clamp plate 2 is installed on one side of the heat dissipation clamp plate 1, and a quick-adjustment component is installed on the heat dissipation clamp plate 2 at a portion connected to the heat dissipation clamp plate 1, and the quick-adjustment component comprises a transmission rod rotatably installed in the middle of one side wall outside the heat dissipation clamp plate, a hand wheel installed at an end of the transmission rod away from the heat dissipation clamp plate 2, two belts staggeredly installed in the middle of the transmission rod, a pulley installed at an end of the belt away from the transmission rod, a screw rod 1 installed on the pulley in the middle of the side wall of the heat dissipation clamp plate 2, a sliding cavity provided in a vertically symmetrical manner on a side wall of the heat dissipation clamp plate 2 facing the heat dissipation clamp plate, a slide plate formed on the heat dissipation clamp plate 1 and matched with the sliding cavity, and a screw hole provided on the slide plate and matched with the screw rod 1.

[0007] By adopting the above technical solution, the transmission rod is rotated by turning the handwheel in the quick-adjustment assembly, and the corresponding rotation of the screw rod 1 can be achieved with the help of the two belts while the transmission rod is rotating. After the screw rod 1 is rotated, the slide plate can be easily extended from the slide cavity under the action of the thread transmission, thereby realizing the rapid adjustment of the installation space size between the heat dissipation clamp plate 1 and the heat dissipation clamp plate 2.

[0008] Furthermore, the transmission rod is connected to the belt in a nested manner, and the pulley is connected to the belt in a nested manner.

[0009] By adopting the above technical solution, the pulley is mainly used to transmit the power of the transmission rod to the pulley, so as to realize the rotation of the pulley.

[0010] Furthermore, the screw rod 1 penetrates through the second side wall of the heat dissipation clamping plate and is rotatably connected to the second heat dissipation clamping plate.

[0011] By adopting the above technical solution, it is possible to ensure that the screw rod 1 can be easily rotated and adjusted relative to the heat dissipation clamping plate 2.

[0012] Furthermore, the screw rod 1 is threadedly connected to the screw hole, and the slide plate is slidably connected to the slide cavity.

[0013] By adopting the above technical solution, after the screw rod 1 rotates, the slide plate will be extended under the guidance of the thread transmission and the sliding cavity, thereby realizing flexible adjustment of the installation space size between the heat dissipation clamping plate 1 and the heat dissipation clamping plate 2.

[0014] Furthermore, a thermally conductive silicone pad is bonded to the inner wall of the heat dissipation clamping plate 1 and the heat dissipation clamping plate 2, and a support plate is respectively installed at the bottom end of the heat dissipation clamping plate 1 and the heat dissipation clamping plate 2.

[0015] By adopting the above technical solution, the heat dissipation clamping plate I, the heat dissipation clamping plate II and the heat conduction silica gel pad are the main components for realizing the heat dissipation of automotive lithium batteries. The support plate can leave a space corresponding to the convenient rotation of the pulley at the bottom ends of the heat clamping plate I and the heat dissipation clamping plate II.

[0016] Furthermore, fixing components are respectively installed at the four corners of the outer walls of the heat dissipation clamping plate I and the heat dissipation clamping plate II. The fixing components include a screw sleeve fixed on the heat dissipation clamping plate I, a screw rod II installed in the screw sleeve, a mounting plate installed at the end of the screw rod II away from the screw sleeve, and a fixing bolt fixed on the mounting plate and located on one side of the screw rod II.

[0017] By adopting the above technical solution, adjusting the distance of the screw rod II in the screw sleeve can align the fixing plate with the mounting frame pre-fixed in the vehicle, ensuring that the fixing bolt can be screwed into the corresponding limit hole to achieve the reliable installation of the whole heat dissipation plate.

[0018] Furthermore, shock absorption components are also symmetrically installed on both sides of the heat dissipation clamping plate I and the heat dissipation clamping plate II respectively. The shock absorption components include spring rods fixed on the heat dissipation clamping plate I in a vertically symmetrical manner and a buffer plate installed on the telescopic parts of the two spring rods.

[0019] By adopting the above technical solution, the buffer plate will be buffered under the action of the spring rod when being impacted, so as to avoid damaging the fixed automotive lithium battery.

[0020] Furthermore, both the heat dissipation clamping plate I and the heat dissipation clamping plate II are connected with the screw rings at the fixed parts of the corresponding spring rods in a threaded manner, and the telescopic parts of the spring rods are welded to the buffer plate.

[0021] By adopting the above technical solution, it can ensure the flexible telescoping of the buffer plate along with the spring rod.

[0022] The utility model has the following beneficial effects compared with the prior art:

[0023] The utility model installs a quick adjustment component between the heat dissipation clamping plate one and the heat dissipation clamping plate two, so that when the heat dissipation plate is in use, the handwheel in the quick adjustment component can be rotated to make the transmission rod rotate. While the transmission rod rotates, the corresponding screw rod one can be rotated by means of two belts. After the screw rod one rotates, the slide plate can be conveniently extended from the slide cavity under the action of screw thread transmission, so as to quickly adjust the installation space size between the heat dissipation clamping plate one and the heat dissipation clamping plate two. Since only one rotation is required in this adjustment method to quickly adjust the installation space size between the heat dissipation clamping plate one and the heat dissipation clamping plate two, the cumbersome operation of repeatedly screwing and fixing bolts is avoided, so that the clamping and fixing efficiency of the detachable heat dissipation hanging plate for the water-cooled row of the automotive lithium battery pack and the automotive lithium battery is improved, and the efficient installation and use of the heat dissipation plate are facilitated.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] like Figures 1-3 As shown, in the present embodiment, a detachable heat sink for a car lithium battery pack water cooling row comprises a heat sink 1, a heat sink 2 7 is installed on one side of the heat sink 1, a quick adjustment component 6 is installed at a portion of the heat sink 2 7 connected to the heat sink 1, and the quick adjustment component 6 comprises a transmission rod 607 rotatably installed in the middle of a side wall outside the heat sink, a hand wheel 601 installed at the end of the transmission rod 607 away from the heat sink 2 7, two belts 602 staggeredly installed in the middle of the transmission rod 607, a pulley 603 installed at the end of the belt 602 away from the transmission rod 607, a screw 1 605 installed at the middle of the side wall of the heat sink 2 7 facing the pulley 603, a sliding cavity 604 symmetrically arranged on the side wall of the heat sink 2 7 facing the heat sink 1, a slide plate 606 formed on the heat sink 1 and matched with the slide cavity 604, and a screw hole 608 arranged on the slide plate 606 and matched with the screw 1 605.

[0033] Among them, the transmission rod 607 is rotated by rotating the hand wheel 601 in the quick adjustment component 6, and the corresponding screw rod 605 can be rotated with the help of two belts 602 while the transmission rod 607 is rotating. After the screw rod 605 is rotated, the slide plate 606 can be easily extended from the slide cavity 604 under the action of the thread transmission, thereby realizing the rapid adjustment of the installation space size between the heat dissipation clamp plate 1 and the heat dissipation clamp plate 2 7.

[0034] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the transmission rod 607 is connected to the belt 602 in a nested manner, and the pulley 603 is connected to the belt 602 in a nested manner. The pulley 603 is mainly used to transmit the power of the transmission rod 607 to the pulley 603 so as to realize the rotation of the pulley 603.

[0035] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the screw 1 605 passes through the side wall of the heat dissipation clamp plate 2 7 and is rotatably connected to the heat dissipation clamp plate 2 7, which can ensure the convenient rotation adjustment of the screw 1 605 relative to the heat dissipation clamp plate 2 7. The screw 1 605 is threadedly connected to the screw hole 608, and the slide plate 606 is slidably connected to the slide cavity 604. After the screw 1 605 rotates, the slide plate 606 will be extended under the guidance of the thread transmission and the slide cavity 604, thereby realizing the flexible adjustment of the installation space size between the heat dissipation clamp plate 1 and the heat dissipation clamp plate 2 7.

[0036] As Figures 1-2 shown, in this embodiment, heat dissipation clamping plates 1 and 7 are adhesively bonded with heat-conducting silica gel pads 5 on their inner walls. A support plate 4 is also respectively installed at the bottom ends of the heat dissipation clamping plates 1 and 7. The heat dissipation clamping plates 1, 7 and the heat-conducting silica gel pads 5 are the main components for realizing the heat dissipation of automotive lithium batteries. The support plate 4 can leave a space for the corresponding belt pulley 603 to rotate conveniently at the bottom ends of the heat dissipation clamping plates 1 and 7.

[0037] As Figure 1 and Figure 3 shown, in this embodiment, fixing components 2 are respectively installed at the four corners of the outer walls of the heat dissipation clamping plates 1 and 7. The fixing component 2 includes a stud 201 fixed on the heat dissipation clamping plate 1, a screw rod two 203 installed in the stud 201, a mounting plate 204 installed at the end of the screw rod two 203 away from the stud 201, and a fixing bolt 202 fixed on the mounting plate 204 and located on one side of the screw rod two 203. Adjusting the distance of the screw rod two 203 in the stud 201 can align the fixing plate with the pre-fixed mounting frame in the vehicle, ensuring that the fixing bolt 202 can be screwed into the corresponding limit hole to realize the reliable installation of the whole heat dissipation plate.

[0038] As Figure 1 and Figure 3 shown, in this embodiment, shock absorption components 3 are also symmetrically installed on both sides of the heat dissipation clamping plates 1 and 7 respectively. The shock absorption component 3 includes spring rods 302 fixed on the heat dissipation clamping plate 1 in a vertically symmetric manner and a buffer plate 301 installed on the telescopic parts of the two spring rods 302. When the buffer plate 301 is impacted, it will be buffered under the action of the spring rods 302 to avoid damaging the fixed automotive lithium battery. The heat dissipation clamping plates 1 and 7 are both connected to the fixed parts of the corresponding spring rods 302 by screw rings, and the telescopic parts of the spring rods 302 are welded to the buffer plate 301, which can ensure the flexible telescoping of the buffer plate 301 with the spring rods 302.

[0039] The specific implementation process of this embodiment is as follows: When in use, first adjust the installation space size between the first heat dissipation clamping plate 1 and the second heat dissipation clamping plate 7 through the quick adjustment component 6. Then, fix the first heat dissipation clamping plate 1 and the second heat dissipation clamping plate 7 on the outside of the water-cooled row of the automotive lithium battery. Next, just under the action of the fixing component 2, fixedly connect the whole heat dissipation plate with the fixing frame pre-installed in the vehicle, and then the heat dissipation plate can be put into use. During the use process, under the action of the shock absorption component 3, the influence of external impact vibration on the first heat dissipation clamping plate 1 and the second heat dissipation clamping plate 7 can be effectively avoided. By means of the quick adjustment component 6, when the heat dissipation plate is in use, the handwheel 601 in the quick adjustment component can be rotated to make the transmission rod 607 rotate. So, while the transmission rod 607 rotates, the corresponding first screw 605 can be rotated by means of the two belts 602. After the first screw 605 rotates, the slide plate 606 can be conveniently extended from the sliding cavity 604 under the action of screw thread transmission, so as to realize the rapid adjustment of the installation space size between the first heat dissipation clamping plate 1 and the second heat dissipation clamping plate 7. Since in this adjustment method, only one rotation is needed to realize the rapid adjustment of the installation space size between the first heat dissipation clamping plate 1 and the second heat dissipation clamping plate 7, the cumbersome operation of repeatedly screwing the fixing bolts 202 for fixation is avoided, thus improving the clamping and fixing efficiency of the detachable heat dissipation hanging plate for the water-cooled row of the automotive lithium battery pack and the automotive lithium battery, and facilitating the efficient installation and use of the heat dissipation plate.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
