Description

Technical Field

[0001] The utility model relates to the field of stage lamps, and more specifically, to a chassis with a heat insulation function and a stage lamp provided with the chassis. Background Art

[0002] In the prior art, the switch power supply of the stage light is located at the bottom chassis. However, due to the small space of the bottom chassis and the relatively concentrated arrangement of the switch power supply and various components, the temperature generated is relatively high, which leads to a high shell temperature of the bottom chassis of the stage light. Since the shell of the bottom chassis and the handle are mostly integrally formed, the heat is conducted through heat conduction so that the handle has the same temperature as the shell of the bottom chassis. When the handle is used to carry the lamp, it is easy to cause contact burns to the technician.

[0003] In order to solve the above problems, the chassis shell needs to be improved in terms of isolating the temperature difference between the inside and outside, increasing the heat dissipation area, and improving the heat conduction speed. Utility Model Content

[0004] The utility model aims to overcome at least one defect (deficiency) of the above-mentioned prior art and provides a chassis with heat insulation function and a stage light provided with the same, which are used to solve the technical problems that the shell temperature of the chassis at the bottom of the stage light is too high, the chassis has too many heat dissipation directions, technicians who directly contact the shell are likely to be scalded, the temperature isolation between the heat source in the chassis and the shell is insufficient, the heat dissipation area of ​​the shell in contact with the heat source in the chassis is too small, and the heat conduction speed from the heat source in the chassis to the shell is not fast enough.

[0005] The technical solution adopted by the utility model is a chassis with a heat insulation function, which includes a stage light base, a heat dissipation cover and an outer shell. The stage light base is arranged below the heat dissipation cover and abuts against the bottom edge of the heat dissipation cover to form a cavity together. The outer shell is covered outside the cavity, and heat insulation gaps are formed between the left side, the right side, the front side and the rear side of the cavity and the outer shell.

[0006] It is beneficial to cover the heat of the stage light chassis within the cavity, so that the heat is confined within the cavity instead of directly contacting the shell; it is beneficial to further avoid the heat of the stage light chassis being directly transferred to the shell through the thermal insulation gap between the shell and the cavity, thereby reducing the possibility of high-temperature burns caused by direct contact with the shell; it is beneficial to increase the heat dissipation area in direct contact with the heat source through the design of the heat dissipation cover, thereby accelerating the technical effect of heat conduction from the heat source to the heat dissipation cover.

[0007] The heat dissipation cover includes a top plate arranged at the top, a front side plate for mounting a display screen, and a rear side plate for mounting a plug interface. The front side plate and the rear side plate are connected to the top plate through locking members, and the outer shell includes a front shell and a rear shell arranged corresponding to the front side plate and the rear side plate.

[0008] It is beneficial to directly contact the heat source of the stage light chassis through the top plate, so as to realize the rapid dissipation of heat; it is beneficial to provide support for the network cable, wire plug board and display screen in the heat of the stage light chassis through the front side plate and the rear side plate, and also to strengthen the connection stability between the heat dissipation cover and the stage light base.

[0009] The shell comprises a left-hand carrying shell and a right-hand carrying shell with handles located on the left and right sides of the cavity.

[0010] It is beneficial to prevent heat from being transferred to the shell through direct contact through the heat insulation gap formed by the left-hand carrying shell, the right-hand carrying shell and the heat dissipation cover, thereby causing contact burns to personnel; it is beneficial to realize easy transportation of the stage lamp through the left-hand carrying shell and the right-hand carrying shell.

[0011] The top plate comprises lateral walls extending downward along left and right edges, and the lower surfaces of the lateral walls abut against the bottom edge of the stage light base.

[0012] The lateral wall is advantageous for isolating the heat source in the stage light chassis from the left-hand carrying shell and the right-hand carrying shell, thereby preventing direct heat dissipation from causing the shell to be hot when in direct contact with the shell; at the same time, the lateral wall can also firmly fix the stage light base to the left-hand carrying shell and the right-hand carrying shell, thereby further increasing the stability of the stage light base.

[0013] The lateral wall includes a raised corner portion and a recessed middle portion, and the recessed middle portion is arranged between the two raised corner portions.

[0014] It is beneficial to provide support for the top plate through the raised corners, and also to provide support for the front shell, rear shell, left handle plate, right handle plate, front side plate and rear side plate, thereby forming a stable structure covering the stage light base; it is beneficial to isolate the high temperature of the heat source in the stage light chassis through the space between the recessed middle part and the left handle plate and the right handle plate.

[0015] The left-handed carrying shell and the right-handed carrying shell both include a concave surface and a handle, the handle is installed at both ends of the concave surface, the concave surface correspondingly covers the outside of the concave middle part of the lateral wall, and the handle correspondingly spans the outside of the two raised corners.

[0016] It is beneficial to prevent technicians from getting burned when lifting the stage lamp through the heat-insulating material of the left-hand carrying shell and the right-hand carrying shell; it is beneficial to form sufficient carrying space through the concave surface to facilitate force; it is beneficial to balance the distribution of force through the handle spanning the two raised corners.

[0017] The distance between the raised corner portion and the recessed middle portion in the left and right directions is smaller than the distance between the handle and the concave surface in the left and right directions.

[0018] By making the recessed thickness of the lateral wall smaller than the protruding thickness of the handle in the left and right directions, the heat transfer distance between the handle and the chassis is further increased, thereby avoiding heat transfer and reducing the possibility of burns to technicians when carrying the stage light.

[0019] It also includes a power module, which is attached to the top plate.

[0020] It is beneficial to transfer the heat to the top plate in a timely manner in the form of direct contact through the power module attached to the top plate, so that the heat inside the chassis can be quickly discharged.

[0021] The surface of the top plate is provided with heat dissipation ribs, and / or the surface of the stage light base is provided with heat dissipation ribs.

[0022] It is beneficial to increase the heat dissipation area of ​​the top plate by the heat dissipation ribs penetrating the left and right edges of the top plate, thereby accelerating the heat exchange speed between the top plate and the outside world; it is beneficial to make the width of the heat dissipation rib greater than or equal to the width of the middle part of the recess, which can avoid damage to the structural stability of the raised corner and widen the heat dissipation area as much as possible; it is beneficial to arrange heat dissipation ribs on the surface of the stage light base to accelerate the heat dissipation speed.

[0023] A stage lamp further comprises a chassis, a support arm pivotally connected to the upper part of the chassis, and a lamp head pivotally connected to the inner side of the support arm.

[0024] It is helpful to improve the heat dissipation effect of the stage light, a high-temperature device, through the heat dissipation structure on the chassis.

[0025] Compared with the prior art, the beneficial effects of the utility model are: limiting the heat dissipation direction of most of the stage light chassis to be directly transferred to the outside of the stage light chassis, avoiding the heat dissipation direction of the chassis to be directly transferred to the handle, causing the technician to directly touch the handle and cause burns, and improving the temperature insulation between the heat source in the stage light chassis and the handle.

DETAILED DESCRIPTION

[0030] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0031] Example 1

[0032] like Figure 1-2 As shown, this embodiment provides a chassis with a heat insulation function, which includes a stage light base 10, a heat dissipation cover and an outer shell. The stage light base 10 is arranged below the heat dissipation cover and abuts against the bottom edge of the heat dissipation cover to form a cavity together. The outer shell is wrapped around the cavity, and heat insulation gaps are formed between the left side, right side, front side and rear side of the cavity and the outer shell.

[0033] In this embodiment, a plurality of heat sources are arranged on the stage light base 10. The bottom of the stage light base 10 includes a boss. The inner and outer sides of the boss are provided with snap-in positions. The heat dissipation cover is snap-into the boss, and the outer shell is snap-into the outside of the boss. Although the heat dissipation cover and the outer shell are both connected to the stage light base 10, an insulating gap is still left between the heat dissipation cover and the outer shell.

[0034] The heat dissipation cover includes a top plate 100 arranged at the top, a front side plate 210 for mounting a display screen, and a rear side plate 310 for mounting a plug interface. The front side plate 210 and the rear side plate 310 are connected to the top plate 100 through locking members, and the outer shell includes a front shell 200 and a rear shell 300 arranged corresponding to the front side plate 210 and the rear side plate 310.

[0035] In this embodiment, the top plate 100, the front side plate 210, and the rear side plate 310 are all die-cast sheet metals. The front shell 200, the rear shell 300, the left-handed shell 400, and the right-handed shell 500 are all shells of the stage light chassis 10 that are in direct contact with the technician. The die-cast sheet metal material is used to directly contact the heat of the heat source in the stage light chassis 10 and guide the heat to be preferentially dissipated toward the top plate 100. The front and rear sides of the top plate 100 are respectively used to connect the front side plate 210 and the rear side plate 310. The front side plate 210 and the rear side plate 310 can not only provide better stability for the connection between the heat dissipation cover and the stage light base 10, but also guide the heat on the front side plate 210 and the rear side plate 310 to be preferentially dissipated toward the top plate 100, further avoiding direct contact of the heat with the shell.

[0036] The housing includes a left-hand carrying housing 400 and a right-hand carrying housing 500 with handles located on the left and right sides of the cavity.

[0037] In this embodiment, the left-hand carrying shell 400 and the right-hand carrying shell 500 are the points of force for technicians to carry the stage light, and are also the parts that technicians directly contact the most. The left-hand carrying shell 400 and the right-hand carrying shell 500 not only reduce the temperature rise caused by heat transfer through the insulation gap, but also can further reduce the possible temperature rise by changing the thermal conductivity of the material.

[0038] In this embodiment, the distance between the front side plate 210 and the front shell 200, as well as the distance between the rear side plate 310 and the rear shell 300 are both at least greater than 1 mm, which can effectively block the heat transfer between the front side plate 210, the rear side plate 310 and the front shell 200, the rear shell 300, thereby avoiding burns caused by direct contact of technicians.

[0039] The top plate 100 includes lateral walls 110 extending downward along left and right edges, and the lower surfaces of the lateral walls 110 abut against the bottom edge of the stage light base 10 .

[0040] In this embodiment, the lateral wall 110 serves as a connecting structure, and the front shell 200, the rear shell 300, the left-handed shell 400, and the right-handed shell 500 are all screwed to the top plate 100 to form a stable containing structure.

[0041] In this embodiment, the spacing between the lateral wall 110 and the left-handed shell 400 is 2 mm-5 mm, and the spacing between the lateral wall 110 and the right-handed shell 500 is 2 mm-5 mm. The 2-5 mm gap avoids direct contact and heat transfer, further reduces the temperature rise of the left-handed shell 400 and the right-handed shell 500, and protects technicians from being burned.

[0042] The lateral wall 110 includes a raised corner portion and a recessed middle portion, and the recessed middle portion is disposed between the two raised corner portions.

[0043] In this embodiment, the raised corners extend downward along the four corners of the lateral wall 110 to improve the stability of the heat dissipation cover; the recessed middle portion not only widens the insulation space between the heat source in the stage light chassis 10 and the outer shell to avoid direct contact and transfer of heat; it also provides a carrying space for the stage light chassis 10 to facilitate effort.

[0044] The left-handed carrying shell 400 and the right-handed carrying shell 500 both include a concave surface and a handle, the handle is installed at both ends of the concave surface, the concave surface corresponds to cover the outside of the concave middle part of the lateral wall 110, and the handle corresponds to span the outside of the two raised corners.

[0045] In this embodiment, the handle includes one on the left and one on the right side, and the raised corners are two on the left and two on the right side of the heat dissipation cover, and the handle straddles the two raised corners on the same side; the handle and the concave surface not only form sufficient carrying space, but also reduce the temperature difference between the heat source of the stage light chassis 10 and the outer shell through its heat-insulating material, thereby preventing technicians from getting burned when touching the outer shell.

[0046] The distance between the raised corner portion and the recessed middle portion in the left and right directions is smaller than the distance between the handle and the concave surface in the left and right directions.

[0047] In this embodiment, the thickness of the depression formed by the raised corner and the recessed middle on the left side is smaller than the thickness of the raised depression formed by the handle and the concave surface on the right side, so that the handle is further away from the heat transferred from the lateral wall 110, thereby avoiding heat caused by contact.

[0048] It also includes a power module, and the power module 600 is attached to the top plate 100 .

[0049] In this embodiment, the power module 600 is a whole module placed in the middle of the chassis and covered by the heat dissipation cover. The power module 600 is fitted with the top plate 100 in the heat dissipation cover, so that the heat of the power module 600 can be transferred to the top plate 100 through direct contact, thereby quickly dissipating the heat inside the chassis; thermal conductive paste is filled between the top plate 100 and the stage light base 10, which effectively speeds up the heat dissipation through the top plate 100.

[0050] The surface of the top plate 100 is provided with heat dissipation ribs 120 , and / or the surface of the stage light base 10 is provided with heat dissipation ribs 120 .

[0051] In this embodiment, the heat dissipation rib 120 spans the left and right edges of the top plate 100, and the length of the heat dissipation rib 120 along the front-to-back direction is equal to half the length of the top plate 100 along the front-to-back direction. The heat dissipation rib 120 can effectively increase the heat dissipation area of ​​the top plate 100 and enhance the heat exchange efficiency between the top plate 100 and the air, thereby accelerating the heat dissipation of the top plate 100. In this embodiment, the width of the heat dissipation rib 120 at the left and right edges is greater than or equal to the width of the middle part of the recess, which can avoid damaging the structural stability of the raised corners and widen the heat dissipation area as much as possible. In this embodiment, the heat dissipation rib 120 is a hollow tube, and the hollow tube can be filled with media with different thermal conductivities, thereby accelerating the heat dissipation effect of the heat dissipation rib 120.

[0052] Example 2

[0053] like Figure 3 As shown, this embodiment provides a stage light, which further includes the chassis, a support arm 20 pivotally connected to the upper side of the chassis, and a lamp head 30 pivotally connected to the inner side of the support arm 20 .

[0054] In this embodiment, the stage light includes multiple models, and the chassis is adapted to multiple models of support arms and lamp heads. The heat insulation function of the chassis isolates the stage light, a high-temperature appliance, from heat that is directly transferred to the handle, and promotes the heat dissipation effect of discharging the heat to the top.
