Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle-mounted battery pack protection equipment, in particular to a battery bracket for a vehicle chassis. Background Art

[0002] In order to facilitate installation, maintenance, and replacement of new energy vehicle battery packs, they are usually installed on the bottom of the vehicle through a bracket. The battery pack is installed on the bracket, and the bracket is connected to the entire frame of the vehicle chassis. The bracket is an open frame structure that can only be used to fix the battery at the bottom of the vehicle. This structure helps the battery pack to fully contact the outside of the vehicle, thereby facilitating heat dissipation.

[0003] However, in actual use, due to the certain fragility of the battery pack in physical structure, it is easy to be damaged as a whole when it is bumped or damaged in appearance, and it is even prone to explosion. In order to fully protect the battery pack, vehicle users generally install a protective plate on the chassis to completely cover the bottom of the battery pack. Even if the chassis bottoms out or bumps on unpaved roads, the protective plate can protect the battery pack to a certain extent. However, this additional design is not conducive to the heat dissipation needs of the battery pack. When the vehicle is driving at a low speed, the heat is not easy to discharge, which can easily cause the battery to overheat. Based on this, the inventor believes that further technical improvements should be made to the bracket itself. Utility Model Content

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the following technical problems in the prior art: During the installation process of the current vehicle-mounted battery pack, whether the bottom is armored or not, it will cause heat dissipation and protection problems to the battery pack.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a battery bracket for a vehicle chassis, comprising the following parts:

[0031] The frame 1 has an inner side and an outer side connected to each other, which can be understood as the upper and lower parts of the frame 1 respectively, and the inner side, i.e., the upper part, is Figure 1 and Figure 3 The part shown in the perspective is used to install the battery pack, and the outer side, that is, the lower part, is Figure 2 and Figure 4 The part presented in the perspective is facing the ground after installation;

[0032] A heat dissipation component 2 is provided on the frame 1, and the heat dissipation component 2 is used to dissipate heat from the inner side of the frame 1, thereby dissipating heat from the battery pack. The heat dissipation component 2 may be a fan or other component;

[0033] A protective plate 3 movably arranged on the frame 1 and a driving assembly 4 arranged on the frame 1, wherein the protective plate 3 can maintain isolation or release of the inner and outer sides of the frame 1 through the driving assembly 4, that is, respectively achieve shielding or release of the bottom of the battery pack;

[0034] Based on the above, when the battery pack is installed at the bottom of the vehicle through the utility model, the battery pack is arranged inside the frame 1, and the frame 1 is still connected to the vehicle chassis. When the vehicle is driving on an unpaved road, the driving assembly 4 is controlled to drive the protective plate 3 to move to Figure 1 and Figure 2 The battery pack is in the state shown, thereby covering the bottom of the battery pack to protect the battery pack, thereby preventing the battery pack from being bumped on rugged roads such as potholes, unevenness or bumps. At this time, the battery pack is in a relatively closed state, and the heat dissipation component 2 can be used for auxiliary heat dissipation; when the vehicle is driving on a road with higher quality, the protective plate 3 can be moved to the state shown. Figure 3 and Figure 4 In the state shown, the bottom of the battery pack is in an open state, thereby meeting the normal heat dissipation requirements of the battery pack. Compared with the prior art, the bracket provided by the utility model can be manually adjusted to better meet the heat dissipation and protection requirements of the battery pack in a multi-section driving environment, and is more practical;

[0035] In addition, it is worth noting that in the present invention, the installation method of the battery pack on the frame 1 can be selected as needed. For example, when the shock absorption effect of the vehicle is good, the battery pack can be directly set on the frame 1 by hard connection. When the shock absorption effect of the vehicle is average, the battery pack can also be set on the frame 1 by cooperating with some shock absorption components. The use period of the heat dissipation component 2 can also be flexibly selected. It is not only used when the bottom of the battery pack is blocked. For example, when the battery pack does not have a good heat dissipation effect by relying on normal external airflow, the heat dissipation component 2 can also be enabled to further cooperate with heat dissipation.

[0036] Further, see Figure 1-5 One end of the protective plate 3 is rotatably matched with the frame body 1, and an inclined groove 5 is also constructed on the protective plate 3. The driving component 4 includes a sliding frame 401 slidably set on the frame body 1, and a limiting column 402 extending into the inclined groove 5 is constructed on the sliding frame 401. The driving component 4 also includes a power element. The sliding frame 401 can obtain driving force through the power element to slide; when the sliding frame 401 slides through the power unit, the limiting column 402 moves linearly, thereby cooperating with the inclined groove 5 to control the swing of the protective plate 3, so as to realize the control of the active state of the protective plate 3. This structure makes the driving process of the protective plate 3 simple and convenient, and in actual use, the number of the protective plates 3 is set to multiple, so that the movement of all protective plates 3 can be conveniently controlled simultaneously through the cooperation of a sliding frame 401.

[0037] Further, see Figure 6 The power element here may include a driving motor 403 arranged on the frame 1, and a threaded column 404 rotatably arranged on the frame 1, the threaded column 404 is threadedly matched with the sliding frame 401, and is connected to the driving motor 403. When the driving motor 403 is working, it drives the threaded column 404 to rotate to cooperate with the thread effect to realize the linear movement of the sliding frame 401. Through the cooperation of the thread effect, the position of the sliding frame 401 can be better locked and limited, thereby realizing the limitation of the state of the protective plate 3.

[0038] Further, see Figure 1-4 The frame 1 is constructed with ventilation holes 6 located at two opposite ends of the inner side, and there are multiple ventilation holes 6 at both locations. The heat dissipation component 2 is arranged at the ventilation holes 6. The ventilation holes 6 of the heat dissipation component 2 can be designed as round holes, so as to better cooperate with the installation of the heat dissipation component 2. Through the cooperation of the two ventilation holes 6, when the heat dissipation component 2 is working, the airflow enters the inner side of the frame 1 from one ventilation hole 6 and flows out from the other, so that the airflow can form a relatively stable directional flow inside the frame 1.

[0039] Further, see Figure 1 and Figure 3 Regarding the specific connection position of the battery pack on the inner side of the frame 1, a carrier frame 7 is also fixedly arranged on the frame 1, and the carrier frame 7 can be integrally forged with the frame 1. The inner and outer sides of the frame 1 are separated by the carrier frame 7, that is, the upper part of the carrier frame 7 is used to place the battery pack, and the lower part thereof faces the bottom of the vehicle. When the battery pack is installed, it is directly hard-connected or soft-connected with the carrier frame 7. In addition, when the protective plate 3 moves to isolate the inner and outer sides of the frame 1, the protective plate 3 is directly attached to the bottom of the carrier frame 7, so that it can be leaned on by the function of the carrier frame 7; the cooperation of the carrier frame 7 can further improve the structural strength of the entire frame 1, and at the same time, the protective plate 3 has a supporting effect. When the protective plate 3 is severely hit or bumped by hard objects on the road, the protective plate 3 is forced upward, so that the protective plate 3 can be vertically resisted by the carrier frame 7 to prevent the protective plate 3 from being damaged or deformed and directly touching the battery pack above.

[0040] Example 2

[0041] The utility model provides a use mode of the drive assembly 4 in cooperation with human control in Example 1. The difference between this embodiment and the above is that the drive assembly 4 can also be used in cooperation with a vibration sensor. Specifically, the vibration sensor is used to detect the vibration of the vehicle, and the electrical signal between the vibration sensor and the drive motor 403 is coordinated;

[0042] Based on this, when the vehicle travels on an unpaved road, the entire vehicle will vibrate. When the vibration sensor detects a vibration signal and reaches a threshold state, it indicates that the vehicle has traveled on an unpaved road. At this time, the drive motor 403 can be directly controlled to work through the coordination of electrical signals, so as to ultimately achieve the activity control of the protective plate 3, so that it automatically moves to maintain the shielding state of the battery pack to prevent obstacles in the current road section from causing collision or bumping against the battery pack. When the vibration signal disappears, the protective plate 3 automatically releases the shielding state of the battery pack through this process again, thereby improving the use effect of the utility model;

[0043] Regarding the model of the vibration sensor, for example, the SW-420 type can be used, which can be set in any area of ​​the vehicle other than the wheel part to detect the vibration of the vehicle body. Regarding the coordination of electrical signals, for example, the drive motor 403 and the vibration sensor can be directly connected to the vehicle ECU, so that the collected vibration signal is processed by the vehicle ECU and the corresponding electrical drive signal is sent to the drive motor 403 to realize the automatic movement of the protective plate 3.

[0044] Example 3

[0045] This embodiment continues to provide another use of the drive assembly 4, that is, the drive assembly 4 can also be used in conjunction with a ranging radar. Specifically, the ranging radar is used to measure the ground clearance of the vehicle chassis, and the ranging radar and the drive motor 403 are still coordinated by electrical signals.

[0046] Based on this, through the cooperation of the ranging radar, the distance between the bottom of the vehicle and the ground can be measured in real time. When the distance is less than the threshold, the drive motor 403 is activated to keep the protective plate 3 active to cover the bottom of the battery pack; for example, when the vehicle is driving on an uneven road section or a place with a raised speed bump, the minimum distance between the raised part and the bottom of the vehicle reaches the threshold state. With the cooperation of the electrical signal, the protective plate 3 is active to cover the bottom of the battery pack to prevent the raised part from colliding or bumping the battery pack, and in this state, if Figure 2 As shown, the protective plate 3 is also in a retracted state at this time, so as to reduce the phenomenon that the protective plate 3 itself is bumped or collided with the road surface;

[0047] Regarding the type of ranging radar, the SRR320 model can be used, which can be installed on the chassis of the vehicle. The number can be set to multiple and evenly distributed near the front and rear of the vehicle. Regarding the coordination method of the electrical signals here, the ranging radar and the drive motor 403 can still be directly connected to the vehicle ECU.

[0048] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
